DETAILED DESCRIPTION

[0039] While this disclosure is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosure and is not intended to limit the broad aspect of the disclosure to the embodiments illustrated. It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and features of one embodiment may be employed with other embodiments as one of ordinary skill in the relevant art would recognize, even if not explicitly stated herein. Further, descriptions of well-known components and processing techniques may be omitted so as to not unnecessarily obscure the embodiments of the present disclosure. The examples used herein are intended merely to facilitate an understanding of ways in which the present disclosure may be practiced and to further enable those of ordinary skill in the art to practice the embodiments of the present disclosure. Accordingly, the examples and embodiments herein should not be construed as limiting the scope of the present disclosure, which is defined solely by the appended claims and applicable law.

[0040] Generally, this disclosure describes several embodiments of sliding tray systems 10 that are arrangeable in a variety of different orientations, both alone and in combination. Typically, as shown in FIG. 1A, the sliding tray system 10 is utilized in storage units 11 where the rear of the storage unit 11 is not easily accessible, for example, in elevated storage units 11. As shown in FIG. 1A, users often have to climb ladders to access elevated storage units 11. Such storage areas may have a variety of sizes, such as being approximately five feet wide and approximately seven feet deep, or alternatively over eight feet wide and approximately seven feet deep. Of course alternate size storage areas may be provided, some of which are even deeper in size. When the user is on the ladder it is difficult to access the rear of the elevated storage unit 11 without getting off the ladder and physically entering the storage unit 11. However, the process of getting off the ladder and entering the storage unit 11, and then attempting to get back on the ladder from the elevated storage unit 11 may be difficult and physically challenging to some users. Accordingly, there is a need for a device to allow the user to access the rear of the elevated storage unit 11 without having to physically enter the elevated storage unit 11.

[0041] Referring now to the figures, and initially to FIGS. 1A-9, there is shown an embodiment of a sliding tray system 10 with various accessories that allows a user to safely and easily access the rear of an elevated storage unit 11. The sliding tray system 10 generally comprises a tray 12, first, second and third retaining walls 14, 16, 18, supports 20 for the retaining walls, a plurality of rollers 22, roller supports 24, first and second tracks 26, 28, and a pull strap 30. Additionally, the sliding tray system 10 may include a push bar 31 to assist the user in pushing the tray 12 back in the storage unit 11. The push bar 31 may be removably connected to the ladder with the use of a clamp holder 33 as shown in FIGS. 1A and 1B.

[0042] In one embodiment the tray 12 comprises a well 32 having a bottom wall 34, side walls 36 and flanges 38 extending from the side walls 36 at a top of the well 32. In one embodiment the depth of the well 32, which is approximately the same as the height of the side walls 36, is approximately between one and a half to two inches, however, that dimension may be larger or smaller with different embodiments of the tray 12. The tray 12 has a first end 40 and a second end 42, and a first side 44 and a second side 46. In one embodiment there are side walls 36 adjacent each of the first end 40, second end 42, first side 44 and second side 46 of the tray 12. Preferably, the pull strap 30 is provided adjacent the first end 40 of the tray 12, and the retaining walls 14, 16, 18 are preferably provided adjacent the second end 42 of the tray 12. All or some of the flanges 38 may extend outwardly from the side walls 36 as shown in FIG. 2, or alternately, while not shown in the figures, some of the flanges 38 may extend inwardly from the side walls 36, such as the flanges 38 at the first and second ends 40, 42 of the tray 12. Preferably, the flanges 38 at the first side 44 and second side 46 of the tray 12 extend outwardly to cover the rollers 22 and tracks 26, 28 for safety purposes. Accordingly, in one embodiment the flanges 38 are approximately two inches wide, however, not all of the flanges 38 need to be the same width. In a preferred embodiment, the length or depth of the tray 12 is approximately 41 inches long. Accordingly, when used in a seven foot deep storage unit 11 this embodiment of the tray 12 may take up approximately half of the overall depth of the storage unit 11.

[0043] In one embodiment, the tray 12 is made of 16 gauge galvanized steel, however, alternate materials and material thickness may be utilized. Additionally, in one embodiment the tray 12 is made of multiple components that are welded together. In alternate embodiments, however, certain components of the tray 12 may be made of the same sheet stock that is bent to form the tray 12. Alternately, components of the tray 12 may be made of aluminum, plastic or some other rigid material.

[0044] In one embodiment the sliding tray system 10 has a plurality of retaining walls. In one embodiment the retaining walls are secured to the flanges 38 of the tray 12 adjacent the first side, second side and second end of the tray 12. As best shown in FIGS. 2, 7 and 8, in one embodiment the retaining walls 14, 16 and 18 are positioned adjacent the second end 42 of the tray 12. The retaining walls 14, 16 and 18 preferably assist in preventing any boxes or other materials that the user may put on the tray 12 from falling backwards behind the tray 12. The retaining walls 14, 16 and 18 may comprise a wall member 50, a top flange 52 and a bottom flange 54. Additionally, in one embodiment the first and third retaining walls 14 and 18 have a side flange 56. If necessary, in a preferred embodiment, the retaining walls 14, 16 and 18 are fixedly connected together, such as by welding, however, in alternate embodiments the retaining walls 14, 16 and 18 are separate components. In a preferred embodiment the retaining walls 14, 16 and 18 are secured to the flanges 38 of the tray 12, such as with fasteners. Further, in one embodiment supports 20, such as auxiliary supports 20, are used to assist in providing rigidity to the top of the overall retaining wall structure. For example, as shown in FIG. 2, in one embodiment an auxiliary support 20 may join the top of the first retaining wall 14 with the top of the second retaining wall 16 at an area toward the center of the second retaining wall 16, and similarly in one embodiment another auxiliary support 20 may join the top of the third retaining wall 18 with the top of the second retaining wall 16 at an area toward the center of the second retaining wall 16. Further, in one embodiment the second retaining wall 16 may be made of two components that are secured together at a joint 58 to create a single retaining wall 16.

[0045] Referring to FIGS. 7 and 8, in one embodiment the retaining walls 14, 16 and 18 may not extend the entire length of the depth of the tray 12, and thus in one embodiment the retaining walls adjacent the first and second sides of the tray do not extend from the second end of the tray all the way to the first end of the tray. In one embodiment, the length or depth of the tray 12 is approximately 41 inches long, and the length of the first and third retaining walls 14 and 18 is approximately 24 inches. Further, in one embodiment the height of the retaining walls 14, 16 and 18 is approximately 36 inches high. This height of the retaining walls 14, 16 and 18 is typically less than the overall height of the storage unit 11, however the height of the retaining walls 14, 16 and 18 may be shorter or higher depending on the application.

[0046] In one embodiment, the retaining walls 14, 16 and 18 are made of 22 gauge galvanized steel, however, alternate materials and material thickness may be utilized. Additionally, in one embodiment the retaining walls 14, 16 and 18 are made of multiple components that are welded together. In alternate embodiments, however, certain components of the retaining walls 14, 16 and 18 may be made of the same sheet stock that is bent to form the retaining walls 14, 16 and 18. Alternately, components of the retaining walls 14, 16 and 18 may be made of aluminum, plastic or some other rigid material. And, in alternate embodiments supports may not be needed.

[0047] The sliding tray system 10 typically has a plurality of rollers 22 as shown in FIGS. 2 through 8 and 11. The rollers 22 are preferably connected to the tray 12, and in various embodiments are connected either to an exterior wall of the bottom wall 34 of the well 32 of the tray 12 or to the exterior wall of the side walls 36 of the tray 12. In one embodiment, roller supports 24 are connected or fixed to the tray 12, such as the exterior of the tray 12, and the roller supports 24 secure the rollers 22 to the tray 12. In one embodiment, the roller supports 24 comprise first and second roller supports 24 adjacent the first end 40 of the tray 12, and third and fourth roller supports 24 adjacent the second end 42 of the tray 12. In one embodiment, one of the plurality of rollers 22 is secured to each of the first, second, third and fourth roller supports 24, respectively. Preferably, the roller supports 24 allow the rollers 22 to be adjustable therein to properly align the tray 12 with respect to the tracks 26, 28. In one embodiment, the rollers 22 comprise a wheel 60 and a shaft 62. The wheels 60 are rotatable with respect to the shaft 62. And, in one embodiment the shaft 62 extends into the roller support 24 and is secured to the roller support 24 and linearly moveable to be adjustably positioned within the roller supports 24 for adjustment purposes to adjust the distance of the rollers from the side walls of the well of the tray 12. As shown in FIGS. 5 and 6, the wheels 60 of the rollers 22 are generally provided under the side flanges 38 of the tray 12.

[0048] As shown in FIGS. 2-4 and 7-8, to provide for the sliding tray system 10 to traverse from the front of the storage unit 11 to the rear of the storage unit 11, the sliding tray system 10 includes opposing first and second tracks 26, 28. In one embodiment the first track 26 is adjacent the first side 44 of the tray, and the second track 28 is adjacent the second side 46 of the tray. In one embodiment, the tracks 26, 28 generally comprise a U-shaped member with a bottom wall 70, side wall 72 and top wall 74 to receive and retain the wheel 60 of the rollers 22. The rollers 22 can traverse linearly in the first and second tracks. The tracks 26, 28 generally extend from the front of the storage unit 11 to the rear of the storage unit 11 to allow a user to move the sliding tray 12 from the front of the storage unit 11, as show in FIGS. 7 and 9, to the rear of the storage unit 11, as shown in FIGS. 8 and 10, and then back as desired.

[0049] In one embodiment, the tracks 26, 28 have an opening 76 in the top wall 74 of the tracks 26, 28 toward a front 78 of the tracks 26, 28 to allow for insertion of the front and rear rollers 22, respectively, of the sliding tray system 10. The tracks 26, 28 also have feet 80. In one embodiment the feet 80 comprise an angle bracket. The feet 80 are secured to the tracks 26, 28 and then also secured to the floor of the storage unit 11 to secure the tracks 26, 28 therein, and, in a preferred embodiment, to raise the tracks 26, 28 a distance off the floor of the storage unit 11. Referring to FIG. 3, to position the tray 12 with the attached rollers 22 in the tracks 26, 28, the rear rollers 22 are first inserted through the opening 76 in the top wall 74 of the tracks 26, 28. The tray 12 is then moved toward the rear of the tracks 26, 28 until the front rollers 22 can be inserted into the opening 76 in the top wall 74 of the tracks 26, 28 as shown in FIG. 4.

[0050] To connect the retaining walls 14, 16 and 18 to the tray 12, it is preferred to use a stopper 84 as shown in FIGS. 5 and 6. The stopper 84 is secured to the front roller(s) 22 of the tray 12 and prevent the tray 12 from moving back and forth in the tracks 26, 28 to allow the retaining walls 14, 16 and 18 to be more easily secured to the tray 12 as explained herein. After the retaining walls 14, 16 and 18 are secured to the tray 12 the stopper 84 can be removed. In an alternate embodiment, the opening 76 in the top wall 74 of the tracks 26, 28 may be covered with a plate (not shown).

[0051] After the tray 12 is properly inserted in the tracks 26, 28 and the retaining walls 14, 16 and 18 are secured to the tray 12, the tray 12 may be loaded by a user in the front of the storage unit 11 and then slid back to the rear of the storage unit 11, as shown in FIGS. 9 and 10, so that additional items can be located in the front of the storage unit 11, but not on the tray 12. Then, when one wants to access the items on the tray 12 the user can slide the tray 12 back to the front of the storage unit 11 as shown in FIG. 10.

[0052] In various embodiments, including when the width of the tray 12 is large, a supplemental roller system 90 may be employed to provide additional support for the tray 12. For example, as shown in FIGS. 11-13, in one embodiment, auxiliary rollers 92 may be secured to the bottom wall 34 of the tray 12. In one embodiment two auxiliary rollers 92 positioned toward the first and second ends 40, 42, respectively, of the tray 12 are utilized. In an alternate embodiment, however, only one auxiliary roller 92 is employed toward a middle of the tray 12. In on embodiment, the auxiliary rollers 92 are positioned about a centerline of the tray 12. The auxiliary rollers 92 may be secured directly to the tray 12, or a supplement support 94 may be secured to the tray 12 to provide additional rigidity to the tray 12 and the auxiliary rollers 92 may be secured to the supplemental support 94. Additionally, in another embodiment a flat track 96 may be secured to the floor of the storage unit 11, as shown in FIG. 11, to provide a support surface for the rollers 94. However, in alternate embodiments one or both of the supplemental support 94 and/or the flat track 96 may not be needed.
