DESCRIPTION OF EXAMPLE EMBODIMENTS
[0050] Referring to Figures 1 through 4, an exemplary embodiment of the flange protector 10 comprises a body member 34, a projection member 46, and at least one attachment member 52. Projection member 46 is coupled to said body member 34 and is configured to form a sealing engagement with a bore 16 of a flanged conduit 12. The at least one attachment member 52 is coupled to said body member 34.
A flanged conduit 14 contains a flange 12 disposed on at least one end of the conduit 14, and a bore 16 extending longitudinally through the conduit 14 and the flange 12. The flange 12 has a front surface 22, a rear surface 24, and a peripheral surface 26 extending along the periphery therebetween. The bore 16 is defined by the inner surface 20 of the conduit 14.
[0051] Flange 12 may include at least one bolt hole 28 disposed through the body of the flange 12 intermediate the bore 16 and the peripheral surface 26 of the flange 12. A plurality of bolt holes 28 may be arranged around the bore 16 as needed. The at least one bolt hole 28 is a generally cylindrical opening which spans the distance between the front surface 22 and the rear surface 24. A bolt hole bore 25 extends through the bolt hole 28 and is defined by an internal surface 27. The bolt hole 28 has a front opening 23 proximate the front surface 22 of the flange 12, and a rear opening 29 proximate the rear surface 24 of the flange 12. A purpose of at least one bolt hole 28 is to provide a means for securement of the flange protector 10 and/or other flanged conduits 14 or the like. A further purpose may allow ventilation through the bolt holes 28 as needed.
[0052] Flange 12 may include a raised face member 30. The raised face 30 extends outward, away from the front surface 22 of the flange 12 proximate the bore opening 17. The raised face 30 at least partially encircles the bore opening 17 and is disposed intermediate the bore 16 and at least one bolt bore 28. The raised face member 30 is defined by an outer edge 31 extending along the outer perimeter of the raised face 30 intermediate the raised face 30 and the bore hole 28, and an inner edge 32 extending along the inner perimeter of the raised face 30 intermediate the raised face 30 and the bore 16. In some embodiments the inner edge 32 may be aligned with the inner surface 20 of flanged conduit 14.
[0053] The body member 34 of the flange protector 10 comprises a generally planar structure having an outer surface 40 and an opposite inner surface 42. Body member 34 has a perimeter. Referring to Figure 2, the body member 34 may comprise varying thicknesses along its length. The variations may occur due to the configuration of the front surface 22 of the flange 12 and/or the configurations of the flange protector 10 itself.
[0054] The inner surface 42 of the flange protector 10 may be raised from the front surface 22 of the flange 12 wherein there is no significant contact between the inner surface 42 and the front surface 22. A purpose of the lack of significant contact is to help prevent damage to the front surface 22 of the flange 12. This purpose may, in part, allow for proper connection between adjacent conduits during installation.
[0055] Alternatively, the surfaces 42 and 22 may have at least some contact therebetween. Alternatively, the inner surface 42 may lay at least partly flush against the front surface 22 of the flange 12.
[0056] The body member may contain a raised face depression 44 corresponding to the raised face on the flange 12. The depression 44 may provide a gap 11 between the raised face 30 and the depression 44, or may lie adjacent to the raised face 30. The depression 44 may lie flush with the surrounding inner surface 42 of the protector 10 or may extend into the body member to a greater degree than the surrounding inner surface 42. Alternatively, depending on the thickness of the body member surrounding the raised face depression 44, the depression 44 may extend further than the inner surface 42.
[0057] The projection member 46 is positioned along the inner surface 42 of the body member 34. The projection member 46 may be integrally formed with the body member 34, fixedly or removably attached to the body member 34, or a combination of the foregoing. The projection member 46 is generally shaped and sized to cooperate with the bore 16 of the flanged conduit 14. The projection member 46 is disposed proximate the bore 16 of the conduit 14 when the flange protector 10 is positioned with respect to the flange 12. At least a portion of the projection member 46 may be inserted within the bore 16. The interaction between the portion of the projection member 46 within the bore 16 and the bore 16 may form a seal; however, the formation of a seal is not necessary.
[0058] The projection member 46 contains a base 45 distal the body member 34. The projection member 46 also contains a peripheral surface 47 extending around the projection member 46 intermediate the body member 34 and the base 45.
[0059] The projection member 46 may have a varying outer diameter 48. For example, the outer diameter 48 may be greatest proximate the body member 34 and may taper slightly inward along the peripheral surface 47 wherein the outer diameter 48 may be smallest proximate the base 45. This type of configuration may allow for at least partial insertion of the projection member 46 within the bore 16. [0060] Further, the projection member 46 may be constructed of at least semi- compressible material allowing for a seal between the peripheral surface 47 and the inner surface 20 of the flanged conduit 14 when at least a portion of the projection member 46 is positioned within the bore 16. The tapering of the projection member 46 is not necessary to produce a seal between the peripheral surface 47 and the inner surface 20 of the flanged conduit 14. Several configurations are possible such as, but not limited to, a fairly uniform peripheral surface 47, increasing girth of the outer diameter 48 proximate the base 45 in relation to the outer diameter 48 proximate the body member 34, a projection member 46 comprised of expandable material, and the like.
[0061] Projection member 46 may be collapsible in that it forms a seal on top of bore 16 with bellows, springs or the like to bias it. Additionally, projection member 46 may not be biased and may sit on top of bore 16.
[0062] Alternatively, the projection member 46 may not enter the bore 16. Alternatively, the projection member 46 may not touch the front surface 22 of the flange 12.
[0063] A purpose of the projection member 46 may be for insertion into and protection of inner bore 13 of flange 12. A further purpose of the projection member 46 may include forming a seal with the bore 16. Another purpose of the projection member 46 may be to aid in proper positioning of the flange protector 10 in relation to the flange 12.
[0064] Referring to Figures 1 through 4, at least one attachment member 52 is provided to secure the flange protector 10 to the flange 12. Various versions of attachment members 52 may be utilized separate and apart from the exemplary embodiments contained within this disclosure. A purpose of the attachment member 52 is to aid in securing the flange protector 10 to the flange 12. A further purpose of the attachment member 52 may be to provide spacing between the body member 34 and the front surface 22 of the flange 12.
[0065] The attachment member 52 depicted in Figures 1 through 4 is an elongated attachment member 82. The elongated attachment member 82 protrudes from the inner surface 42 of body member 34. The elongated attachment member 82 contains a head 49, elongated body 53, and means for coupling said elongated attachment member 82 to a receiving member 58. In the exemplary embodiment, a fastener 54 is used to couple said elongated attachment member 82 to a receiving member 58.
[0066] The head 49 is attached, integrally, fixedly, and/or removably, to the body member 34. The head 49, as depicted, is a generally cylindrical structure, though other configurations may be utilized. A purpose of head 49 is to connect attachment member 52 to raised body 34 of flange protector 10.
[0067] The elongated body 53 is a generally elongated structure that is attached to the head 49 at one of its at least two ends. Alternatively, the head 49 and elongated body 53 are integrally formed, or of varying or similar outer diameters.
[0068] The elongated body 53 ends in the fastener 54. The fastener 54 is distal the head 49. The fastener 54 contains at least one barb 57. The barbs 57 allow for connection of the fastener to the flange protector 10, or other structure, to secure the protector 10. The barbs 57 are inserted into a receiving member 58. The receiving member 58 is positioned on the flange protector 10. The receiving member 58 is sized and structured to accept at least a portion of the fastener 54.
[0069] As shown, at least part of the body member 34, proximate the attachment member 82, extends beyond the peripheral surface 26 of the flange 12. The extension 38 provides a position for the receiving member 58. The extension 38 may be angularly disposed with respect to the body member 34. The extension 38 may be integrally formed with the body member 34, or otherwise fixedly or removably attached thereto.
[0070] The fastener 54 is inserted at least partially thorough the receiving member 58, thereby securing the attachment end 55 of the attachment member 82. The at least one barb 57 may interact with at least one groove, not shown, contained within the receiving member 58.
[0071] Alternatively, any known or later discovered attachment means may be utilized to attach the attachment member 82 to the receiving member 58. The fastener 54 may have a varying outer diameter to facilitate the coupling with the receiving member 58 as needed. [0072] Attachment member 52 may be constructed of a generally sturdy material that offers some flexibility. Attachment member 52 may be a tie wrap, tie strap, or other connection device or other known or hereafter discovered member. A purpose of attachment member 52 is to assist in securing flange protector 10 to flange 12.
[0073] The exemplary embodiment depicted in Figurers 1 through 4 includes a hood member 36 that at least partially encloses the side surface 26 of the flange 12. A hood member 36 is not necessary and may be omitted from the apparatus, see Figures 13 and 19 for exemplary embodiments that do not contain a hood member 36.
[0074] The hood member 36 may effectively shroud at least a portion of the interface between the body member 34 and the flange 12. The hood member 36 is an extension of the body member 34, and may be an integrally formed extension or fixedly or removably attached to the body member 34. The hood member 36 generally conforms to the size and shape of the respective portion of the flange 12. With the exemplary flange 12 as shown and disclosed, the hood member 36 contains a front portion 64 located proximate the outer surface 22 of the flange 12; a side portion 66 located proximate the peripheral surface 26 of the flange; and a rear portion 68 located proximate the rear surface of the flange 12. A purpose of the hood 36 is to protect the connection surface 22, peripheral surface 26 and rear surface 24 of flange 12. A second purpose of hood 36 is to hold flange protector 10 in place on flange 12. A further purpose of the hood 36 may be to prevent access to debris, water, and other contaminates within any gaps 65 that may be formed between the outer surface 22 of the flange 12 and the inner surface 42 of the protector 10.
[0075] The front portion 64 of the hood 36 may be angled in relation to the adjacent portion of the body member 34. The side portion 66 extends from the front portion 64 generally along the side 26 of the flange 12. The rear portion 68 extends from the side portion 66 and is angled in relation to the side portion 66. The rear portion 68 extends over at least a portion of the rear surface 24 of the flange 12. Hood 36 covers at least a twelfth of said perimeter of said body member 34.
[0076] In operation, the flange protector 10 is aligned with the flange 12 during an aligning step. At least one attachment member 52 is aligned with at least one bolt hole 28. The projection member 46 may be aligned with the bore 16. [0077] The flange protector 10 is installed on the flange 12 in an installing step. The installing step comprises installing a flange protector 10 onto a flanged conduit 14 having a bore 16 extending at least partially therethrough. Installation entails placing the protector 10 onto the front surface 22 of the flange 12 and attaching at least one attaching member 52 in an attaching step. The attaching step comprises inserting the elongated body 53 of the attaching member 82 through a bolt hole 28. The elongated body 53 may have sufficient length to extend completely through the bolt hole 28 and exit through the rear opening 29 of the bolt hole 28. The attachment step further comprises coupling the fastener 54 to the receiving member 58 proximate the attachment end 55. A sealing step comprises sealing said bore 16.
[0078] Alternatively, the projection member 46 may be inserted, at least partially, within the bore 16.
[0079] A sealing step may be performed when desired. The projection member 46 is conformed to sealingly engage the inner surface 20 of the flanged conduit 14 and is at least partially inserted therein. A seal is effectively formed between the bore 16 and the projection member 46. The seal may occur between the peripheral surface 47 of the projection member 46 and the inner surface 20 of the flanged conduit 14, or by other means.
[0080] The projection member 46 may be comprised or an at least semi- compressible material facilitating the sealing step.
[0081] A purpose of insertion component 46 is to protect inner bore 13 of flange 12 from debris and external exposure. A second purpose of insertion component 46 is to assist in securing flange protector 10 on flange 12.
[0082] The structure of body member 34 and/or projection member 46 may allow for protection of the flange 12 while minimizing contact with the front surface 22 and the raised face 30, if present, of the flange 12. Minimizing contact may prevent damage to the flange 12 and may prevent the flange protector 10 from becoming substantially frozen to the flange 12 in sub-freezing temperatures. Additionally, minimizing contact of raised face 34 with flange 12 may allow moisture to exhaust from at least one bolt hole 28 while still protecting the front surface 22 of the flange 12. [0083] When a hood member 36 is included, a hooding step is performed wherein the hood 36 is slidably inserted over the side 26 of the flange 12 during the aligning step, so that the hood 36 at least partially aligns with the side 26 of the flange 12. In the installed orientation, a gap 67 may be defined by the distance between the inner surface 42 of the hood 36 and the peripheral surface 26 of the flange 12. The gap 67 may prevent substantial contact between the hood 36 and the flange 12. The contact may be limited to the front edge 56 of the flange 12 proximate the front surface 22 and the rear edge 62 of the flange 12 proximate the rear surface 24. A purpose of gap 67 may be to minimize the possibility that flange protector 10 will become substantially frozen to flange 12 in sub-freezing temperatures. A further purpose of the gap 67 is to prevent substantial contact between the hood 36 and the flange 12.
[0084] In the exemplary embodiment shown in Figures 1 through 4, the body member 34 only contacts the flange 12 along the front edge 56, the rear edge 62, and proximate the opening 17 of the bore 16.
[0085] Referring to Figure 3, when the flange protector 10 is installed on a flange 12, the rear portion 68 of the hood 36 generally covers the upper portion 78 of the rear surface 24. The hood 36 may be sized and structured to at least partially encircle the conduit 14.
[0086] A removing step encompasses either pushing or pulling the fastener 54 away from the receiving member 58 and withdrawing the attachment member 52 from the at least one bolt hole 28. This method allows flange protector 10 to be reused. Alternatively, the elongated body 53 may be cut. The seal, if a seal was utilized, between the projection member 46 and the bore 16 will be broken. The body member 34 will be pulled away from the flange 12. If a hood member 36 is present, the body member 34 will be removed in the direction of the hood 36.
[0087] Referring to Figures 5 through 7, an alternative attachment member 52 is shown. Specifically, the attachment member 52 includes an insertion member 70 having an insertion end 74 and an opposite upper end 76. The attachment member 52 is shaped and sized to generally conform to at least a portion of at least one bolt hole 28. The outer diameter of the insertion member 70 may be smaller than, equal to, or greater than the inner diameter 78 of the bolt hole 28. The relation of the outer diameter of the insertion member 70 and the inner diameter 78 is dependent on the type of interaction needed between the attachment member 52 and the bolt hole 28, and the material of the attachment member 52. For example, the insertion member 70 may be tapered inwardly toward the insertion end 74 in order to prevent at least a portion of the attachment member 52 proximate the inner surface 42 of the body member 34 from entering the bolt hole 28. This would allow for gap 11 between the inner surface 42 of the body member 34 and the front surface 22 of the flange 12, preventing substantial contact at least in the area proximate the bolt hole 28.
[0088] The attachment member 52 extends away from the body member 34, proximate the inner surface 42. The attachment member 52 may be integrally formed with the body member 34, or fixedly or removably attached thereto. The attachment member 52 may be comprised of an at least semi-compressible material to aid in its attachment to the flange 12. The outer diameter of the peripheral surface 71 of the attachment member 52 may vary, such as tapering inward toward the insertion end 74, to aid in its coupling with the bolt hole 28.
[0089] Attachment member 52 may have an outer opening 75 proximate the upper end 76. The opening 75 may lead to a corresponding orifice 79, or, alternatively, the attachment member 52 may be a generally solid piece. A purpose for the opening 75 may be to allow for compression of the insertion member 70 in order to effect a secure fit between the insertion member 70 and the bolt hole 28.
[0090] Referring to Figure 6, the extension 38 is shown as being angled in respect to the body member 34. No straps are required for this configuration.
[0091] Referring to Figure 7, the hood 36 at least partially covers the rear surface 24 of the flange 12. The hood 36 is shown to conform to at least a portion of the conduit 14; however, other configurations are possible.
[0092] In operation, the attaching step encompasses inserting at least one insertion member 70 at least partially within a bolt hole 28. The attaching step may include applying pressure to the upper end 76 in order to provide a secure fit between the insertion member 70 and the bolt hole 28.
[0093] The removing step, regarding disassembling the attachment member 52, includes removing the insertion member 70 from the interior of the bolt holes 28. This may be accomplished by pulling on the area near the attachment member 52, pushing the insertion end 74 through the bolt hole 28, or using by using tool. If a seal was formed between the attachment member 52 and the bolt hole 28, it would be broken in order to remove the protector 10.
[0094] Referring to Figure 8, the attachment member 52 is similar to the attachment member 52 of Figure 5; however, an elongated attachment member 82 is utilized in addition to the insertion member 70. The insertion member 70 contains an aperture 73 extending therethrough intermediate the opening 75 and the insertion end 74. The aperture 73 is sized to allow passage of the elongated body 53 and fastener 54 but not the head 49 of the elongated attachment member 82.
[0095] The head 49 of the elongated attachment member 82 has an outer diameter that is at least partially greater than a portion of the inner diameter of the aperture 73. This allows for insertion of the elongated body 53 through the aperture 73 but prevents passage of entire head 49.
[0096] The insertion member 70 may have an opening 75 leading to a corresponding orifice 79. The outer diameter of the head 49 is smaller than the orifice 79. This allows for the placement of the head 49 within the orifice 79. The orifice 79 may contain a shoulder 72 proximate the insertion end 74. The shoulder 72 abuts the underside 79 of the head 49 to prevent passage therethrough.
[0097] Alternatively, head 49 is not present and the elongated attachment member 82 is sized and shaped to fasten to itself through the bolt hole 28 and a receiving member 58.
[0098] Alternatively, the aperture 73 may extend longitudinally through a solid insertion member 70 with the head 49, if one is utilized, of the elongated attachment member 82 resting on the surface 40 of the insertion member 70.
[0099] In operation, the attaching step encompasses inserting at least one insertion member 70 at least partially within a bolt hole 28. The attaching step may include applying pressure to the upper end 76 in order to provide a secure fit between the insertion member 70 and the bolt hole 28. The attachment end 55 of the elongated attachment member 82 is then inserted through the aperture 73 and threaded through the bolt hole 28. The fastener 54 is at least partially inserted through the receiving member 58. The receiving member 58 may be disposed within the extension 38 of the body member 34, on the elongated attachment member 82 itself, or at a separate location that will provide for secured placement of the fastener 54. The head 49, if present, may be fully inserted within the orifice 79, if present, or at least partially inserted therein.
[0100] The removing step, regarding disassembling the attachment member 52, includes either pushing or pulling the fastener 54 away from the receiving member 58 and withdrawing the elongated attachment member 82 from the at least one bolt hole 28. Removing the insertion member 70 from the interior of the bolt holes 28. This may be accomplished by pulling on the area near the attachment member 52, pushing the insertion end 74 through the bolt hole 28, or using by using tool. If a seal was formed between the attachment member 52 and the bolt hole 28, it would be broken in order to remove the protector 10. Alternatively, the elongated body 53 may be cut. A purpose of the interaction between the fastener 54 and the receiving member 58 is to secure the elongated attachment member 82 in place. The elongated attachment member 82 is structured so that the elongated body 53 may only contact the flange 12 at the bottom edge 60 of the bolt hole 28, and the rear edge 62 of the flange 12 when the fastener 54 is connected to the receiving member 58. A purpose of the elongated attachment member 82 is to assist in securing the flange protector 10 to the flange 12.
[0101] Referring to Figure 9, an alternative embodiments for the projection member 46 and the attachment member 52 are shown. Further, the body member 34 is depicted without the optional extension segment 38 or hood member 36.
[0102] The walls 99 and base 45 of the projection member 46 define a depression 93 formed in the surface of the body member 34. The base 45 of the projection member 46 may be configured for sealing engagement with the bore 16. Alternatively, the base 45 may be at least partially inserted into the bore 16 without forming a seal. Alternatively, the base 45 may not be inserted into the bore 16.
[0103] In the depicted exemplary embodiment, the projection member 46 forms a seal or alternatively at least partially inserts into the bore 16. Gap 11 is defined by the inner surface 42 of the body member 34 and the front surface 22 of the flange 12. The seal or at least partial insertion of the base 45 within the bore 16 may prevent debris, water, or other contaminates that may enter the gap 11 from entering the bore 16 of the conduit 14.
[0104] A peripheral guard 112 may be disposed radially outside of peripheral surface 98. A purpose of peripheral guard 112 is to provide additional protection for connection surface 22 of flange 12. Alternative embodiments may be constructed without peripheral guard 112.
[0105] The attachment member 52 is comprised of at least one deflectable leg 96 extending from the inner surface 42 of the body member 34. The deflectable leg 96 may be formed integral with the body member 34, or may be fixedly or removably attached thereto.
[0106] The deflectable leg 96 has an attached end 100, an opposite free end 102. The deflectable leg 96 may be made from plastic or other flexible material. The attached end 100 includes a seating portion 104 which is sized and structured for at least partial insertion into at least one bolt hole 28 of the flange 12. The seating portion 104 may be sized wherein a portion of the outer diameter of the seat 104 is greater than at least a portion of the inner diameter 78 of the bolt hole 28. This disparity allows the seating portion 104 to prevent the inner surface 42 of the body member 34 from substantially contacting the front surface 22 when installed on a flange 12. Alternatively, the outer diameter of the deflectable leg 96 may vary, such as having the outer diameter of the seating position 104 less than the inner diameter 78, allowing for some contact or for substantial contact between the inner surface 42 of the body member 34 and the front surface 22.
[0107] A clip portion 106 is disposed intermediate the free end 102 and the attached end 100. The clip portion 106 includes a locking edge 110 protruding generally laterally away form the free end 102. The clip portion 106 is sized so that it may pass through at least one bolt hole 28 and at least partially emerge through the rear opening 29 of the bolt hole 28. The locking edge 110 is disposed along the clip 106 of the deflectable leg 96 such that it may couple with at least a portion of the rear surface 24 of the flange 12 proximate the bottom edge 60 of the bolt hole 28. This coupled interaction allows for securement of the flange protector 10 onto the flange 12 once installed. [0108] Referring to Figure 9A, an alternative embodiment of the deflectable leg 96 is shown. The flange 12 is shown with a gap 7 contained within the body 4 of the flange 12. The gap 7 is disposed intermediate the front surface 22 and the rear surface 24 of the flange 12. The deflectable leg 96 is sized such that it is capable of at least partial insertion into the bolt hole 28. The locking edge 110 of the attachment member 52 couples with the intermediate edge 130 of the flange 12 securing the flange protector 10 to the flange 12.
[0109] In operation, the attaching step includes inserting at least one attachment member 52 comprising a deflectable leg 96 into at least one bolt hole 28 until the locking edge 110 of the deflectable leg 96 functionally couples with the appropriate edge 60 or 150 located on the flange 12. The deflectable leg 96 may be inserted through the bolt hole 28 wherein at least a portion extends past the rear opening 29 of the bolt hole 28, or the deflectable leg 96 may insert only a portion of the way through the bolt hole 28.
[0110] The seating portion 104 may come to rest in the bolt hole 28 at the point where it approximates inner diameter 78 of bolt hole 28. A purpose of the at least one deflectable leg 96 is to secure the embodiment of Figure 12 in place on flange 12.
[0111] Seating portion 104 may be sized and structured to prevent the inner surface 42 of the body member 34 from contacting the front surface 22 and the raised face 30 of the flange 12. The body member 34 may cover at least one bolt hole 28 when installed on a flange 12.
[0112] The removal step may include manipulating the free end 102 of the deflectable leg 96 such that the locking edge 110 is uncoupled from the edge 60 or 150. Finger pressure, or other means, may be utilized as needed. Once the locking edge 110 no longer substantially engages the edge 60 or 150 the deflectable leg 96 may be pushed or pulled through the bolt hole 28. This method allows the apparatus to be reused. Alternatively, the clip portion 106 may be severed from flange protector 10, allowing the remaining portion of the deflectable leg 96 to be passed back through the bolt hole 28.
[0113] Referring to Figures 10 through 13, alternative embodiments of the hood 36 and attachment member 52 are shown. [0114] The hood member 36 extends axially around the perimeter 176 of the body member 34, and extends from the perimeter 176 of the body member 34 proximate the inner surface 42. The hood member 36 forms a generally annular protrusion that provides coverage of the gap 11 between the inner surface 42 of the flange protector 10 and the front surface 22 of the flange 12. A purpose of this coverage is to prevent debris, water, and other contaminants from entering the gap 11.
[0115] The body member 34 has at least one ridge 122 formed along the outer surface 34. The at least one ridge 122 extends radially from the depression 93. It should be noted that the depression 93 is not required, the projection member 46 depicted in any of the exemplary or alternative embodiments herein, or any other version that encompasses the scope of this disclosure, may be used. The at least one ridge 122 has at least one receiving member 58 extending at least partially through the body member 34. The at least one receiving member 58 is designed to engage at least a portion of the fastener 54 of at least one attachment member 52. A purpose of the ridge 122 may be to reinforce the flange protector 10.
[0116] The connection end 134 of at least one attachment member 52 may be integrally formed with the hood 36, or fixedly or removably attached thereto. Generally, the position of the attachment member or members 52 corresponds to the position of at least one ridge 122. The elongated body 53 extends from the connection end 134 and ends at the attachment end 55 positioned distal the hood 36.
[0117] In operation, the aligning step includes aligning at least one receiving member 58 with at least one bolt hole 28.
[0118] The installing step includes affixing the flange protector 10 onto the front surface 22 of a flange 12 such that the hood 36 extends at least partially over the side 26 of the flange 12 and at least one receiving member 58 aligns with at least one bolt hole 28.
[0119] The attaching step includes inserting the attachment end 55 of the attachment member 52 into the bolt hole 28 through the rear opening 29. Inserting the fastener 54 at least partially within the receiving member 58 such that at least one barb 57 is engaged therein. Alternatively, other known or later discovered means may replace the barbs 57 described herein in order to effect attachment. The attachment end may extend through the body member 34 as shown in Figure 14.
[0120] The hood 36 may only contact the peripheral surface 26 of the flange 12 at a connection point 126 proximate the front edge 56 of the flange 12. Beveled surface 132 may not contact the peripheral surface 26 of the flange 12. The beveled surface 132 is designed to minimize contact between the attachment member 52 and the peripheral surface 26 of the flange 12. Minimizing contact of at least one attachment member 52 with the flange 12 may prevent substantial freezing of the attachment member 52 to the peripheral surface 26 of the flange 12 in sub-freezing temperatures.
[0121] Referring to Figure 12, the exemplary embodiment of Figure 10 is shown without a flange 12 in order to assist the reader in understanding how at least one attachment member 52 is wrapped back toward the inner surface 42 of the body member 34.
[0122] The removing step may include pulling or pushing the fastener 54 from the receiving member 58 and slidably removing the flange protector 10 from the flange 12. This method allows the embodiment of Figure 10 to be reused. Alternatively, the attachment member 52 may be cut along the elongated body 53 or elsewhere in order to facilitate removal.
[0123] Referring to Figures 14 through 17, an alternative embodiment of Figure 10 is shown. At least one receiving member 58 protrudes from the inner surface 42 of the body member 34. At least one receiving member 58 is positioned to correspond to at least one bolt hole 28 of a flange 12. The receiving member 58 may be integrally formed with the body member 34, or fixedly or removably attached thereto. The receiving member 58 extends radially from the body member and is shaped and configured to fit at least partially within a corresponding bolt hole 28.
[0124] The outer diameter of the receiving member 58 may be tapered wherein the upper end 143 of the receiving member 58 is greater that the inner diameter 78 of the bolt hole 28. This prevents the receiving member 58 from completely entering the bolt hole 28 providing a gap 11 between the front surface 22 of the flange 12 and the inner surface 42 of the body member 34. Alternatively, the receiving member 58 may be configured to fully extend within the bolt hole 28 allowing for contact between the front surface 22 and inner surface 42.
[0125] Alternatively, as depicted in Figure 21, gap 11 may result from the angling of the body member intermediate the projection member 46 and the side wall 139 in relation to the top of the walls 99 of the depression 93. It should be noted that the depression 93 is not required, the projection member 46 depicted in any of the exemplary or alternative embodiments herein, or any other version that encompasses the scope of this disclosure, may be used. The angling allows for a gap 11 preventing substantial contact between the body member 34 and the front surface 22 of the flange 12. Contact does occur at the upper edge 56 of the flange 12. In this embodiment, the outer diameter of the receiving member 58 may be equal to or smaller than the inner diameter 78 of the bolt hole 28 while still providing a gap 11 between the flange protector 10 and the flange 12.
[0126] Alternatively, the receiving member 58 may not extend even partially within the bolt hole 28.
[0127] The attachment member 52 is coupled to the body member 34 proximate at least one bolt hole 28 by the connection end 134. The connection end 134 may be integrally formed from the body member 34, or fixedly or removably attached thereto. The elongated body 53 extends from the connector 134, ending in an attachment end 55 that is distal the body member 34. The fastener 54 contains at least one barb 57. Alternatively, the attachment member 52 and receiving member 58 may include threads, or any other known or later discovered fastener may be utilized.
[0128] An aperture 146 is disposed within the receiving member 58 intermediate the body member 34 and the insertion end 140. The aperture 146 has at least one groove 148 positioned within its interior. The aperture 146 is sized to accept at least a portion of the fastener 54.
[0129] A gap 160 may be disposed along a portion of the side 147 of the aperture 146 proximate the at least one groove 148. A function of the gap 160 is to allow the size of the receiving member 58 to be manipulated. This manipulation may act to at least temporarily increase the size of the aperture 146 to accept insertion of an enlarged attachment member 52. [0130] In operation, the aligning step includes aligning at least one receiving member 58 with at least one bolt hole 28.
[0131] The installing step includes installing at least one receiving member 58 proximate at least one bolt hole 28.
[0132] The attaching step includes inserting the attachment end 55 of at least one attachment member 52 at least partially through the rear opening 29 of a bolt hole 28. At least partially inserting the fastener 54 into the aperture 146 such that the fastener 54 may functionally couple with the receiving member 58. Functional coupling may include allowing at least one groove 148 of a receiving member 58 to engage at least one barb 57 of an attachment member 52 causing the attachment member 52 to be secured in the receiving member 58.
[0133] The removal step includes pulling on the elongated body 53 with force sufficient to separate the barbs 57 of attachment member 52 from the corresponding grooves 148 of the receiving member 58. This method of removal allows the apparatus to be subsequently used. Alternatively, elongated body 53 may be cut, allowing the apparatus 10 to be removed from the flanged pipe 12.
[0134] In alternative embodiments, the apparatus may have more or fewer receiving members 58 and attachment members 152. In alternative embodiments, raised body 138 may completely cover the depression 93.
[0135] In alternative embodiments, the apparatus may have more or fewer attachment members 52 and more or fewer corresponding receiving members 58.
[0136] In alternative embodiments, the apparatus may have more or fewer removable attachment members 82 and more or fewer corresponding receiving members 58.
[0137] In alternative embodiments, the apparatus may have more or fewer bore plugs 70 or deflectable legs 96.
[0138] In alternative embodiments of any of the above described embodiments, flange protector 10 may be made to fit different flange 12 sizes and configurations, including but not limited to those without raised faces 30. [0139] In alternative embodiments of any of the above described embodiments, flange protector 10 may include a body member 34 that substantially contacts the front surface 22 of the flange 12.
[0140] In alternative embodiments of any of the above described embodiments, the projection member 46 may be fixedly or removably attached to the body member 34.
[0141] Throughout the description and claims of this specification, the words "comprise" and "contain" and variations of the words, for example "comprising" and "comprises", means "including but not limited to."
