Interlocking tabs and notches and interfitting registration locks are provided so that intermediate layers can use back-to-back roll supports that have been securely joined together. The roll support is preferably formed from a strong, flexible, thermoformable resinous polymeric plastic material.

Description

TECHNICAL FIELD

This disclosure relates to improvements in support cradles useful for the stable support of roll stock, including, for example, improved support cradles used in the support of cylindrical rolls of paper or the like.

BACKGROUND

“Roll stock” is a term that is used in various industries to describe cylindrical rolls or tubular rolls of an elongate, thin material that may be advantageously stored and shipped by winding the elongate material into a multilayer, wound or rolled generally cylindrical configuration. Such items include paper products, plastic film products, thin gauge metals, roofing sheets, and various other thin, elongate strips of materials.
Many cylindrical or tubular shaped rolls are packed on pallets for storage and for shipping. Packing of roll stock is often provided via tiers of rolls. Once method of storing and shipping roll stock involves securely locating such rolls in a horizontal configuration above pallets. In order to safely and securely stabilize and support cylindrical or tubular rolls in a horizontal position, stacking supports have often been employed.
In the field of roll supports, there still remains a need for an improved roll stacker design which can be manufactured utilizing a material that minimizes the storage space requirements of roll supports, so as to free up warehouse space. Further, a strong, weather-proof, preferably recyclable material that can be utilized in the production of compactly stackable roll supports is desirable. Finally, it would be desirable to provide a roll support design that assures that when roll supports are used in a “back-to-back” configuration, such roll supports can be secured each to the other to provide a reliable, securable, stackable configuration.
Especially when securing multiple roll stock pieces in a horizontal fashion, it would be a distinct and important improvement to provide roll supports that are quickly and easily secured each to the other, so that adjacent upper and lower roll supports are effectively prevented from slipping apart. Thus, the important advantages of a roll support product providing such desirable features in a workable roll support cradle design can be readily appreciated.

An attempt has been made to draw the figures in a way that illustrates at least those elements that are significant for an understanding of the various embodiments and aspects of the invention. However, various other elements of a roll cradle with locking tabs, especially as applied for different variations of the functional components illustrated, as well as different renditions of artistic aspects of such functional components, may be utilized in order to provide a robust roll cradle design with secure interlocking tabs. Further, various features, including optional or alternate features, may be utilized in order to provide a compact, efficiently nestable, reliable structural material for a roll stacking support with locking tabs.

DETAILED DESCRIPTION

Turning now to FIG. 1, a perspective view of a roll support 20 is provided. In addition to the embodiment provided in FIG. 1, in other embodiments, such roll supports 20 may generally utilize, at least in part, configurations as described in detail in several of my earlier patents, namely (a) U.S. Pat. No. 6,322,034, issued Nov. 27, 2001, (b) U.S. Pat. No. 6,209,839, issued Apr. 3, 2001, and (c) U.S. Pat. No. 6,474,613 B2, issued Nov. 5, 2002, the disclosures of each of which are incorporated into this detailed description in their entirety by this reference.
As better appreciated by reference to FIG. 9, roll supports 20 are designed for receiving and supporting stacked tiers of tubular or cylindrical roll stock 22. When used singularly, a roll support 20 _Acan be placed below a first tier T₁(for example, rolls 22 ₁and 22 ₂of roll stock 22) when such first tier T₁of roll stock 22 is placed on a pallet 24 for shipment. When multiple tiers of roll stock 22, for example, T₁, and T₂(for example, rolls 22 ₃and 22 ₄) as illustrated in FIG. 9, are placed on a pallet 24 for shipping, then “back-to-back” roll supports 20 _Aand 20 _Bmay be utilized between tiers of roll stock, such as between tier T₁and tier T₂. Another embodiment for the commonly encountered use of a plurality of roll support in such fashion may be seen in FIG. 1 of the U.S. Pat. No. 6,474,613 B2, just noted above, where a roll support is provided to support up to four rolls, horizontally, and may be stacked, for example, three tiers high, or more.
Roll supports 20 as illustrated in FIG. 1 can be manufactured in stand alone, nestable and stackable units. This allows for compact nesting, which thus allows compact storage of roll supports after their manufacture and before their use to support roll stock. In order to take maximum advantage of this quality of the roll supports disclosed herein, roll supports 20 can be manufactured from a strong, flexible, resinous plastic polymeric material. Resinous plastics which may be utilized for the roll support 20 include high-density polymers that produce a strong, yet flexible final product. A resinous plastic polymer material that can be thermoformed can be utilized to provide a desired final shape for a suitable roll support apparatus 20. On suitable resinous plastic material found to be useful is polyethylene terephthalate material, commonly known by the abbreviation “PET”. Instead of providing a cushioning support, as would be desired when protecting a fragile article such as glass, or light bulbs or the like, roll supports 20 for most roll stock applications must be strong and resistant to deformation. Such applications are ideal for PET, since PET resin forms a high strength product with good strength in all directions. Also, many businesses now prefer that materials be manufactured from recycled materials. The disclosed roll supports 20 are easily fabricated from recycled plastic materials. In the manufacture of roll supports, suitable recycled plastics are relatively easy to reprocess. PET, as with a great variety of plastic materials, is initially segregated at time of disposal, after which it is typically kept clean and uniform during the entire recycling process. This process substantially enhances the likelihood of retaining desirable material properties in a finished roll support made from recycled materials.
Another important property which is achieved by the use of PET is that a single roll support 20 can easily be stacked over another roll support 20 with only a slight increase in height. As shown in FIG. 1, the thickness T of the roll support can be as little as from approximately 40 Mils to approximately 60 Mils (or from about 0.04 inches to about 0.06 inches). In one embodiment, the thickness T can be limited to not exceed the lower end of this range, or 40 Mils (0.040 inches). Thus, with such manufactured thickness, roll supports 20 may be stacked from approximately 16 per inch, to about 20 per inch, and even up to as dense as about 26 per inch. Of course, it is desirable from a storage and nesting perspective that thicknesses be provided which occur at the lower end of the stated thickness range. This very small thickness, when nested, is a significant advantage over roll supports that utilize other materials of construction. The nesting compactness just mentioned provides a substantial and significant savings in shipping and storage space, as compared to prior art papier-mâché or other foam or plastic materials. Thus, it is important to note that warehouse space saved in the storage of nested and still unused roll supports can be allotted to other storage needs. Alternatively, the saved storage or shipping space can be used to store or transport additional roll supports and allow the purchase of higher quantities to realize bulk rate cost savings and substantially reduce freight costs.
Attention is again directed to FIG. 1, wherein one embodiment for a roll support 20 for receiving and supporting two or more pieces of roll stock 22 is illustrated. The roll support 20 includes a base 30, which extends along a longitudinal axis indicated by centerline 32. The base 30 includes laterally spaced apart first 34 and second 36 foot portions. Also, base 30 includes first 38 and second 40 end portions, as well as one or more interior portions 42.
As indicated in FIG. 3, a plurality of roll support cradle portions 44 are provided. Each of the roll support cradle portions 44 include an outward surface 46 shaped as an arcuate segment of pre-selected dimensions adapted for securely receiving a piece of roll stock 22 of substantially complementary shape. Also, the roll support cradle portions 44 have a first outer end 50 and a second outer end 52. A first end wall portion 54 and a second end wall portion 56 are provided. The first end wall portion 54 and the second end wall portion 56 extend from the base 30 to the first outer end 50 and the second outer end 52 of the roll support cradle portion 44. Opposing sidewall portions 60 and 62 are provided for each one of the plurality of roll support cradle portions 44. Each of the opposing sidewall portions 60 and 62 are sloped inwardly toward centerline 32 and outwardly from said base 30 and thus toward, and supporting, the companion roll support cradle portion 44.
Along the first foot portion 34 of the base 30, at least one locking tab 64 is provided. Shaped in a cooperative working fashion with tab 64, at least one notch 66 defined by edgewall portions 68 is provided. As more clearly seen in FIG. 2, the notch 66 in second foot portion 36 is defined by edgewall portions 68 to provide an outwardly opening notch 66. The outwardly opening notch 66 includes first 70 and second 72 neck portions. The first 70 and second 72 neck portions provide an inwardly projecting area tending to narrow, along a selected notch edgewall portion, at least some of the outwardly opening notch 66. Overall, the notch 66 is formed in the second foot portion 36 in a manner that in the region of notch 66, the second foot portion 36 has an inner end 74, and the notch edgewall portion 68 includes a proximal edge 76 that is adjacent the inner end 74. Thus, the notch 66 is, in one embodiment, formed in a generally hour-glass shaped opening having a top and a narrowed neck, wherein the proximal edge 76 provides the top of the generally hour-glass shape, wherein the first 70 and second 72 notch neck portions cooperate to provide the narrowed neck portion of the hour-glass shape. Overall, the first 70 and second 72 neck portions are sized and shaped for interlocking detachable engagement with one of the at least one tabs 64.
Tabs 64 are configured as a laterally extending flap having a body 80 that extends from a connection end 82 to an outer end 84. The tabs 64 extend stiffly from the connection end 82 to the outer end 84. However, to provide a manually interlockable method of joining a first and a second support apparatus together to form an intermediate roll support unit 20 _C, seen in FIG. 3, or as further noted in FIG. 9, the tab 64 is at least slightly moveable by pivoting such as is indicated by reference arrows 86 and 88 in FIG. 4, by pivot motion of the outer end 84 with respect to the connection end 82.
In one embodiment the tabs 64 include first 90 and second 92 ear portions. The first 90 and second 92 ear portions located at longitudinally spaced apart locations on the body 80 of tabs 64. In one embodiment, the first 90 and second 92 ear portions extend stiffly from the body 80 along a common plane. However, the first 90 and second 92 ear portions are at least slightly displaceable above and below the common plane, which common plane may, in one embodiment, be defined by the plane of the first foot portion 34.
As illustrated in FIG. 9, an intermediate support apparatus 20 _Cmay be provided for location between two or more lower (T₁) and two or more upper (T₂) pieces of roll stock 22. Such an intermediate roll support apparatus is configured by joining, in secure interlocking relationship, a first support apparatus 20 _Aand a second support apparatus 20 _B. In such a design, the first support apparatus 20 _Aand the second support apparatus 20 _Bare each sized and shaped for complementary back-to-back interlocking engagement. At least one of the at least one locking tabs 64 on the first support apparatus 20 _Ais attached to at least one of the at least one notches 66 in the second support apparatus 20 _B. Also, at least one of the at least one locking tabs 64 on the second support apparatus 20 _Bis attached to at least one of the at least one notches 66 in the first support apparatus 20 _A. The stiffness of the selected material of manufacture should allow the tab 64 to snap fit into notch 66, by interference between neck portion 70 and ear 70, and between neck portion 72 and ear 92.
As is noted in FIG. 3, the roll support cradle portions 46 may, in one embodiment, be slightly spaced apart from the base 30. However, by using the materials of construction described herein above, the vertical stacking space taken up by the roll support 20 is minimized, since the roll support cradle portion 46 may be vertically spaced apart from the upper surface 30 _Uof base 30 by a distance V of as little as about 0.25 inches.
For ease of manufacture, each of the opposing sidewall portions 60 and 62 may be angled outward away from the base 30 and inward toward the longitudinal centerline of the roll support 20 at an angle sigma (Σ) of about 20 degrees (see FIG. 8) with respect to a plane 96 perpendicular to said first base. Further, to strengthen the roll supports 20, the first end wall portion 54 may further include a plurality of strengthening flutes 98. In one embodiment, the strengthening flutes 98 are configured as a long, rounded groove in the first end wall portion 54. As illustrated in FIG. 1, three strengthening flutes 98 are provided in the first end wall portion 54. Likewise, the second end wall portion further 56 may include a plurality of strengthening flutes 102, as seen in FIG. 2. Each of the strengthening flutes 102 may, in one embodiment, comprise a long, rounded groove in the second end wall portion 56. As illustrated for the embodiment shown in FIG. 2, three strengthening flutes 102 are provided in the second end wall portion 56.
As also seen in FIGS. 1 and 2, in one embodiment, one or more strengthening ridges 104 may be provided. The one or more strengthening ridges 104 extend between the second end wall portions 56 of adjacent roll support cradle portions 44. As illustrated in FIG. 2, at least two strengthening ridges may be provided between the second end wall portions 56 of adjacent roll support cradle portions 44.
When roll supports 20 _Aand 20 _Bare joined in interlocking fashion to provide an intermediate roll support apparatus 20 _C, in one embodiment it has been found useful to provide sets of registration locks that are sized and shaped for reliably and securely positioning roll supports 20 _Aand 20 _Bin back-to-back mating engagement. In such embodiments, the base 30 further comprises, along the first foot portion 34, a first set of registration locks 110. Similarly, the base 30 further comprises, along second foot portion 36, a second set of registration locks 112. As illustrated, complementary thimble shaped dimples may be adequate to accomplish the desired registration lock interface. Note that in the embodiment illustrated in FIG. 1, along first foot portion 34 adjacent or toward first end 38, registration locks 110U are provided in an downward manner, extending below base 30, and along first portion 34 adjacent or toward second end 40, registration locks 110M are provided in an upward configuration, extending above base 30. Similarly, but in a fashion for complimentary mating engagement when duplicate roll supports 20 are turned for back-to-back assembly, along the second foot portion 36 adjacent or toward first end 38, registration locks 110M are provided in an upward configuration, extending above base 30, and along first portion 34 adjacent or toward second end 40, registration locks 110U are provided in an downward manner, extending below base 30,
A method providing intermediate roll stocking supports 20 _Cmay be practiced by providing a first support apparatus 20 _A, providing a second support apparatus 20 _B, and then interlocking the first support apparatus 20 _Awith the second support apparatus 20 _B. This may be accomplished by (1) engaging at least some of the at least one or more tabs 64 in the first support apparatus 20 _Awith at least one of the one or more notches 66 in the second support apparatus 20 _B, then (2) engaging at least some of the at least one or more tabs 64 in the second support apparatus 20 _Bwith at least one of the one or more notches 66 in the first support apparatus 20 _A. Then, by interfittingly registering in mating engagement the first set 110 and the second set 112 of registration locks in the first support apparatus 20 _Awith the first set 110 and the second set 112 of registration locks in the second support apparatus 20 _B. Overall, interlocking the first support apparatus 20 _Awith the second support apparatus 20 _B, and interfittingly registering the sets 110 and 112 of registration locks, forms an intermediate roll stocking support 20 _Cin a back-to-back, stable interlocked configuration.
It is to be appreciated that the various aspects and embodiments of a roll cradle with locking tabs and registration locks as described herein is an important improvement in the state of the art. The locking tab for roll cradle just described herein is simple, robust, reliable, and susceptible to use whenever roll cradles are employed in a back-to-back configuration.
