The pedestal includes a base, a head, first and second support members, a threaded support shaft, and first and second threaded nuts. The invention is easy to install and can be made of all non-metalic parts. The base and the head can be constructed identically to minimize the type of parts needed for manufacturing and inventory. The first and second support members can also be constructed identically, further minimizing the parts needed.
Description
- This application is related to and claims priority from earlier filed U.S. Provisional Patent Application No. 61/176,402 titled Adjustable Locking Spacer, filed May 7, 2009.
- The present invention relates generally to an adjustable leveling pedestal to support raised access flooring, and more particularly, but not by way of limitation, to an adjustable leveling pedestal that allows for infinite height adjustment of the floor by moving stopping members along a shaft.
- Adjustable pedestals for flooring are well known in the art, but suffer from significant drawbacks. For example, prior art adjustable spacers have limited vertical positioning, limited ability to adjust the vertical positioning during loading, and are cumbersome to work with and install. Typical adjustable pedestals are provided with a base, a slotted or notched shaft and a top plate. The shaft is received within, and moves in and out of, the base and locks into position with a clip, rod, cotter pin, or similar mechanism. The spacer is only positionable at heights which correspond to the slots or notches on the shaft.
- Also, typical adjustable pedestals are not adjustable while a load is applied. The downward force of the load precludes vertical adjustment of the adjustable pedestal unless something is provided to support or lift the applied load. Prior art pedestals are also difficult to install and cumbersome to work with.
- Therefore, a need exists for an adjustable leveling pedestal that is selectively adjustable when a load is applied. Simple installation and minimal types of part are also desirable. It is to such an adjustable leveling pedestal that the present invention is directed.
- The present invention provides a pedestal to support access flooring. The pedestal includes a base, a head, first and second support members, a threaded support shaft, and first and second threaded nuts. The first support member is inserted into the base and the second support member is inserted into the head. The threaded support shaft is removably inserted into the first and second support members. The first and second threaded nuts are rotatably attached to the support shaft. The first threaded nut abuts the second support member and the second threaded nut abuts the first threaded nut. The first threaded nut can be rotated to move the second support member.

FIG. 5 is a front elevational view of another presently preferred embodiment of an adjustable leveling pedestal. - Referring now to the drawings, and more particularly to
FIGS. 1A and 1B , shown therein is anadjustable leveling pedestal 10 for raising and leveling access flooring panels (seeFIGS. 4A and 4B ) away from asurface 18. Theadjustable leveling pedestal 10 is provided with a topengaging member 22, a bottomengaging member 24, a firstadjustable stop 26, a secondadjustable stop 30 and asupport shaft 34. - In a presently preferred embodiment, the top
engaging member 22 is fabricated to interface with ahead 14. The topengaging member 22 preferably has a generally square cross sectional area, although it may have many different geometries that would be apparent to one of ordinary skill in the art. It will be understood that the geometry of the topengaging member 22 should cooperate with thehead 14 to provide a substantially secure interface, which can preferably be assembled without tools by inserting the topengaging member 22 into thehead 14. The topengaging member 22 is preferably constructed of a plastic or fiberglass material, but can be fabricated out of any suitable material, such as a resin, other plastic polymer, natural material(s) such as a wood or fiber based material, metal (such as steel, titanium, aluminum or blends thereof) and combinations thereof. The topengaging member 22 is provided with aninterface 42 which is fabricated to connect the topengaging member 22 with thesupport shaft 34. In a presently preferred embodiment, theinterface 42 is a bore fabricated such that thesupport shaft 34 fits snugly within theinterface 42, preferably without using tools. - The bottom
engaging member 24 is preferably similar in construction and function to the topengaging member 22 with a generally square cross sectional area, but can also have any number of differing geometries that would be apparent to one of ordinary skill in the art. It will be understood that the geometry of the bottomengaging member 24 should cooperate with, for example, the geometry of abase 46 to provide a substantially secure interface, preferably without using tools. The bottomengaging member 24 is preferably constructed of a plastic or fiberglass material, but can be fabricated out of any suitable material, such as a resin, other plastic polymer, natural material(s) such as a wood or fiber based material, metal (such as steel, titanium, aluminum or blends thereof) and combinations thereof. The bottomengaging member 24 is provided with aninterface 50 which is also made to connect the bottomengaging member 24 with thesupport shaft 34. In a presently preferred embodiment, theinterface 50 is also a bore fabricated such that thesupport shaft 34 fits snugly within theinterface 50, preferably without using tools. The lengths of both the topengaging member 22 and the bottomengaging member 24 should be of sufficient size and the length of their respective bores should be of sufficient depth to receive portions of thesupport shaft 34. - The
support shaft 34 of theadjustable leveling pedestal 10 is provided with afirst end 58 and asecond end 62. Thesupport shaft 34 is preferably made of fiberglass and threaded along its entire length (all threading not shown inFIGS. 1A and 1B ). Thesupport shaft 34 should be of a size that can be snugly fit intointerfaces engaging member 22 and the bottomengaging member 24, respectively, but can be removed with minimal force, preferably without using tools. Thesupport shaft 34 is constructed so as to cooperate with both the firstadjustable stop 26 and the secondadjustable stop 30 to provide height adjustability for theadjustable leveling pedestal 10. Thesupport shift 34 includesthreads 66 that are operable to engage the firstadjustable stop 26 and the secondadjustable stop 30. Other shaft configurations (such as partially threaded) that allow thesupport shaft 34 to engage the firstadjustable stop 26 and the secondadjustable stop 30 may likewise be utilized. - The first
adjustable stop 26 is preferably a plastic flanged nut (flange not shown) for receiving an end of thesupport shaft 34. The flange of the firstadjustable stop 26 is preferably oriented such that the flange abuts the top engagingmember 22. The firstadjustable stop 26 may be fabricated out of any suitable material, for example, a resin or plastic polymer, natural material(s) such as a wood or fiber based material, metal (such as steel, titanium, aluminum or blends thereof), fiber or glass based materials and combinations thereof. As mentioned above, the flange of firstadjustable stop 26 is constructed so as to engage with at least a portion of the top engagingmember 22 in order to hold thetop engaging member 22 in a fixed configuration relative to thebottom engaging member 24. In operation, the firstadjustable stop 26 is secured against a bottom surface 78 of the top engagingmember 22 by turning the firstadjustable stop 26 until it abuts the bottom surface 78 of the top engagingmember 22. - The second
adjustable stop 30 is preferably a standard nut similar in construction and operation to the firstadjustable stop 26. The secondadjustable stop 30 is positioned below the firstadjustable stop 26 and operates to substantially preclude downward movement of the firstadjustable stop 26 along thesupport shaft 34 after the secondadjustable stop 30 has been tightened against the firstadjustable stop 26. - In operation, the first
adjustable stop 26 and the secondadjustable stop 30 are threaded onto thesupport shaft 34. Thefirst end 58 of thesupport shaft 34 is inserted into theinterface 42 of the top engagingmember 22 and thesecond end 62 of thesupport shaft 34 is inserted into theinterface 50 of thebottom engaging member 24, preferably without using tools. To secure thetop engaging member 22, the firstadjustable stop 26 is turned until the flange contacts the bottom surface 78 of the top engagingmember 22. To lock the firstadjustable stop 26 and therefore top engagingmember 22, the secondadjustable stop 30 is turned until it contacts the bottom of the firstadjustable stop 26. The cooperative use of the firstadjustable stop 26 and the secondadjustable stop 30 allow for infinite adjustability and fine adjustments to the overall length of theadjustable leveling pedestal 10. - To selectively increase the height of the top engaging
member 22, thetop engaging member 22 is moved upwardly along thesupport shaft 34 by turning the firstadjustable stop 26 to raise thetop engaging member 22. To lock the firstadjustable stop 26 and therefore top engagingmember 22, the secondadjustable stop 30 is turned until it contacts the bottom of the firstadjustable stop 26. To selectively lower the height of the top engagingmember 22 the secondadjustable stop 30 is turned in the opposite direction, moving the secondadjustable stop 30 downwardly along thesupport shaft 34. Next, the firstadjustable stop 26 is turned in the opposite direction moving the firstadjustable stop 26 downwardly along thesupport shaft 34. Thetop engagement member 22 is then moved downwardly along thesupport shaft 34 until the bottom of the top engagement member contacts the firstadjustable stop 26. The firstadjustable stop 26 and the secondadjustable stop 30 can be turned by hand or using a wrench or other suitable tool. - The
adjustable leveling pedestal 10 is constructed so as to be used for spacing floor panels 14 a distance away from asurface 18. When utilized for spacing floor panels 14 a distance away from thesurface 18, theadjustable leveling pedestal 10 is preferably provided with a channel (not shown) that is bolted to thehead 44. Preferably, the channel can be slid onto the bolts connecting it to the head (or heads) without the use of tools. This can be accomplished by proper spacing of the bolt and a nut so that during installation of the flooring system the channel can be simply slid onto the nut. The channel is preferably long enough to be bolted to as many adjustable leveling pedestals 10 as are needed to support thefloor panels 14 and thereby occupy the area desired for the raised access flooring. In another preferred embodiment, the channel includes a soft material such as foam rubber attached to the top side. The soft material provides an interface between the channel and thefloor panels 14 that prevents thefloor panels 14 from moving and prevents unwanted noise when loads are applied to thefloor panels 14. In another preferred embodiment, thebase 46 is secured to thesurface 18 with an adhesive, as will be readily apparent to one skilled in the art. As stated previously, thebase 46 is configured to mate with thebottom engaging member 24. In one embodiment, thebase 46 is constructed having a vertical support 108 having arecess 112 for receiving thebottom engaging member 24, and abase flange 114 for connecting the base 46 to thesurface 18. Thebase flange 114 is preferably of a square cross section that includes four holes. The adhesive, in addition to securing the base flange 114 (and thereby the base 46), extrudes through the holes to additionally secure thebase 46. Thebase 46 is constructed from any suitable rigid and durable material, for example, a resin or plastic polymer, natural material(s) such as a wood or fiber based material, metal (such as steel, titanium, aluminum or blends thereof), fiber or glass based materials and combinations thereof. Thebase flange 114 of the base 46 may also be secured to thesurface 18 via a fastener such as, for example, threaded fasteners, screws, nails, rivets, in addition to the adhesive. - The
head 44 is substantially identical in construction to thebase 46, though only thehead 44 is typically bolted, such as to the channel (not shown). In one preferred embodiment, thehead 44 is constructed having avertical support 110 having arecess 120 for receiving thetop engaging member 22, and ahead flange 128 for connecting thehead 44 to the channel. Thehead flange 128 of thehead 44 is preferably of a square cross section that includes four holes (not shown) and is preferably bolted to the channel. In a preferred embodiment, the channel runs along the interface ofadjacent floor panels 14 and supports the weight of thefloor panels 14. Thefloor panels 14 are preferably made from fiberglass, and if constructed from such material thefloor panels 14 remain securely on the channel. - Referring now to
FIG. 3 , shown therein is a plurality offloor panels 14, each of which is provided with four adjustable leveling pedestals 10, oneadjustable locking spacer 10 positioned on eachcorner 116. Although a raised floor can be assembled in this fashion, the added benefit of using the channel and a fewer number of adjustable leveling pedestals cannot be realized. - Referring now to
FIG. 4B , shown therein is a misaligned pair of floor panels 14 (channel is not shown). When installingfloor panels 14, if thesurface 124 is not level, thefloor panels 14 will not be level. - When
floor panels 14 are uneven, the height of one or more of thefloor panels 14 may be either raised or lowered to align thefloor panels 14 via theadjustable leveling pedestal 10. By way of non-limiting example, afloor panel 14 having anadjustable leveling pedestals 118A and 118B and abuts anotherfloor panel 14 having anadjustable leveling pedestal floor panel 14 having theadjustable leveling pedestal 122B is positioned at a height lower than thefloor panel 14 having theadjustable leveling pedestal 118A and 118B due to, for example, variations of thesurface 124. To adjust the height of thefloor panel 14 having theadjustable leveling pedestal 122B, the firstadjustable stop 138 of theadjustable leveling pedestal 122B is moved upwardly along thesupport shaft 130, therefore moving the top engaging member 134 upwardly and in-turn, increasing the height of thefloor panel 14. When the desired height of thefloor panel 14 is achieved, the secondadjustable stop 126 is moved upwardly along thesupport shaft 130 until it abuts the bottom of the firstadjustable stop 138. This process may be repeated, extending and retracting theadjustable locking spacer 122B until thecorrect floor panel 14 height is achieved (seeFIG. 4A ). - Referring now to
FIG. 5 , shown therein is another presently preferred embodiment of theadjustable leveling pedestal 200 with channel 202. Ahead 204 is preferably bolted to the channel 202. Similar toFIGS. 1A and 1B , theadjustable leveling pedestal 200 includes a first adjustable stop 208 and a secondadjustable stop 216, secured to a threadedsupport shaft 212. - From the above description, it is clear that the present invention is well adapted to carry out the objects and to attain the advantages mentioned herein as well as those inherent in the invention. While presently preferred embodiments of the invention have been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art and which are accomplished within the spirit of the invention disclosed.
