Description
FIELD

One embodiment of a selective retention system is provided. The system may be used for selectively retaining items on another structure.


BACKGROUND

It is known to add storage-type equipment to vehicles, such as utility and working vehicles, to adapt them to specific applications. For example, a trades-person may have a cargo-type van equipped with shelving, cabinets, drawers and other items designed to carry and store the various tools, equipment and parts needed for a general or particular task. The shelving, cabinets, drawers and other items might be broadly termed organizational applications. Various types of vehicles may be similarly adapted to accommodate the tools, equipment and parts for any number of trades or purposes.


A disadvantage associated these the current organizational applications is that they may not be adapted to adequately or appropriately store or retain items thereon. For example, while the prior art may include shelves, often items placed on a shelf in a vehicle will move during operation of the vehicle as the items have not been properly secured. This can result in the items not only becoming disorganized, but they may also be damaged, or damage the organizational applications, or the vehicle itself. Some known organizational applications might have dividers or other structures to compartmentalize the items, but often these dividers or structures are not sufficient to adequately or appropriately secure the items.


In view of the disadvantages associated with the prior art, it would be advantageous for an organizational application to have a structure that securely, but selectively, permits items to be located thereon.


SUMMARY

In one embodiment, a selective retention system may have at least one side retention rail comprising an attachment portion and a retention portion, wherein the retention portion has a plurality of teeth. The system may also have an end retention rail comprising an attachment portion and a retention portion, wherein the retention portion has at least one aperture.


In another embodiment, a selective retention system may have a first side retention rail and a second side retention rail. Each side retention rail may have an attachment portion, a retention portion and a transition portion connecting the attachment portion with the retention portion. Each retention portion may have a plurality of teeth.


In another embodiment, a selective retention system may have a first side retention rail and a second side retention rail. Each side retention rail may have an attachment portion, a retention portion and a transition portion connecting the attachment portion with the retention portion. The retention portion of the first side retention rail may have a first set of teeth. The retention portion of the second side retention rail may have a second set of teeth facing the first set of teeth. The system may have an end retention rail positioned at least partially between the first and second side retention rails. The end retention rail may have first and second transition portions extending from first and second attachment portions, respectively, to connect with a retention portion. The retention portion of the end retention rail may have an aperture. All the retention portions may be coplanar with one another.

Turning now to FIGS. 1-3, one embodiment of a selective retention system 10 is depicted. The system 10 may have at least one side retention rail 12 comprising an attachment portion 14 and a retention portion 16. In some embodiments, the attachment portion 14 may be a length of material, which may be plate-like in its construction, that extends along the side retention rail 12. The attachment portion 14 may extend along the entire length of the side retention rail 12, or only a portion thereof. In some embodiments, the length of the attachment portion 14 may be greater than a width of the attachment portion 14. It may be that the attachment portion 14 has a substantially constant width along its length. The width may be defined between an inner edge 18 and an outer edge 20. In other embodiments, the width of the attachment portion 14 may vary.


The attachment portion 14 may have an upper surface 22 and a lower surface 24, where the two surfaces 22, 24 may be separated by a substantially constant thickness. The upper and lower surfaces 22, 24 may be substantially planar which may contribute to its plate-like construction. The attachment portion 14 may exist substantially in a single, first plane. Further, in some embodiments, the attachment portion 14 may have a substantially rectangular shape, although other shapes may be used.


At least one aperture 26 may be located in the attachment portion 14. The at least one aperture 26 extends from the upper surface 22 to the lower surface 24. In some embodiments, two apertures 26 are provided along the length of the attachment portion 14. The apertures 26 may be adapted to receive mechanical fasteners therethrough to connect the attachment portion 14 to a substrate 28. Apertures 26, however, are not required as the attachment portion 14 may be connected to the substrate 28 through other structures or devices, including but not limited to welding and/or adhesives.


In some embodiments, the apertures 26 may be located in end portions of the attachment portion 14. It may be that except for the apertures 26, the attachment portion 14 extends continuously without interruption between the end portions. Some embodiments may have the attachment portion 14 as a uniform, integrally formed and one-piece structure.


The attachment portion 14 may be connected to the retention portion 16 by a transition portion 30. In some embodiments, the transition portion 30 may extend along, and perhaps be formed from or with, the inner edge 18 of the attachment portion 14. The transition portion 30 may extend the length of the attachment portion 14 or only a portion thereof. All, or a portion, of the transition portion 30 may be angled with respect to the attachment portion 14, such as at an angle of between approximately 45-90 degrees. The transition portion 30 may extend upwardly and outwardly from the first plane of the attachment portion 14.


The transition portion 30 may have a constant width as it extends along the attachment portion 14. Further, in some embodiments, the transition portion 30 may extend continuously without interruption along its length. The transition portion 30 may be generally rectangular in shape and be uniform, integrally formed and one-piece in its construction. The transition portion 30 may also have a substantially constant thickness along its length defined between an upper surface 31a and a lower surface 31b. The upper and lower surfaces 31a, 31b may be substantially planar.


The retention portion 16 may have an inner edge 32 and an outer edge 34. The inner edge 32 may extend along, in whole or in part, the transition portion 30.

The retention portion 16 may exist substantially in a single, second plane.


In some embodiments, the retention portion 16 may extend parallel to, but not be coplanar with, the attachment portion 14. In these embodiments, the second plane may be located above the first plane. It may be that in some cases, the retention portion 16 does not overlap, such as vertically overlap, with the attachment portion 16.


The outer edge 34 of the retention portion 16 may have a plurality of teeth 40. The teeth 40 may cause the width of the retention portion 16 to vary along the length of the retention portion 16. The teeth 40 may be co-planar with the retention portion 16 and they may be unitary, one-piece and integrally formed with the retention portion 16. The teeth 40 may extend along the entire length of the retention portion 16 or any portion thereof.


In one embodiment, the teeth 40 may be formed in whole or in part by a leading edge portion 42 of the retention portion 16 that may have a reduced width area 44. A first ramp 46 may extend from the reduce width area 44 at an angle away from the inner edge 32. The angle may be such as about 30-60 degrees. The first ramp 46 may transition to a plateau area 48. The plateau area 48 may be substantially linear; the plateau area 48 may extend parallel the reduced width area 44. The reduced width area 44 may have a width that is smaller than the width of the plateau area 48.


The plateau area 48 may transition to a second ramp 50. The second ramp 50 may be angled toward the inner edge 32 such at about 30-60 degrees. The angle and/or length of the second ramp 50 may be the same or different than the first ramp 46.


The first ramp 46, plateau portion 48 and the second ramp 50 may form one tooth of the plurality of teeth 40. Other teeth designs may be used. For example, teeth of other shapes and sizes may be used. In one example, the leading edge portion 42 may be removed.


The second ramp 50 may transition to a valley portion 52. The valley portion 52 may extend in a substantially linear fashion, and be parallel the leading edge portion 42 and/or the plateau area 48. The valley portion 52 may extend along the length of the retention portion 16 approximately the same length as the plateau area 48. The valley portion 52 may be substantially the same width as the reduced width area 44.


The valley portion 52 may separate a first tooth 54 from one or more additional teeth 40 in the retention portion 16. The teeth 40 may be the same, substantially the same or they may be different in size and shape.


In some embodiments, a final tooth 56, located adjacent a trailing edge portion 58, and opposite the leading edge portion 42, may be provided in the retention portion 16. The final tooth 56 may be provided with a first ramp 60, which may transition to a plateau portion 62. In some embodiments, the plateau portion 62 may transition to a rear wall 64 of the retention portion 16. The rear wall 64 may extend substantially transverse the length of the retention portion 16. The plateau portion 62 of the final tooth 56 may have the same or substantially the same width as the plateau areas 48 of the first tooth 54.


The attachment portion 14, the transition portion 30 and the retention portion 16 may be unitary, one piece and integrally formed, or these individual portions 14, 30 and 16 may be separately formed and then joined together such as by welding or with mechanical fasteners.

The rails 12 and/or 68 may be used to secure one or more devices 102 in the same or similar manner as noted above.



FIG. 5 also depicts a pair of rails 12 on an upper exterior surface of the vehicle 114, such as the roof 124. The rails 12 are shown attached to the roof 124 in one orientation and location on the roof 124, but other locations, numbers and orientations are permissible. For example, there may be more than one pair of rails 12 and the rails 12 may or may not be aligned with one another along the roof 124. The rails 12 may be attached to the vehicle 116 in the same or similar manner as discussed above including use of the end retention rail 68 or not. The rails 12 may be used as noted above.



FIGS. 6 and 7 depicts one embodiment of a vehicle interior 126, such as a cargo portion of a vehicle interior. The interior may be defined by the side walls 128, doors, such as rear doors 118 and/or side doors, floor 130, roof 132 and/or partitions 132.


In one embodiment, one or more pairs of rails 12 may be attached to the interior side wall 128 in the same or similar manner as described above. Further, the end retention rails 68 may or may not be used with the rails 12. The rails 12 are depicted laterally offset from one another, but the rails 12 may be located at any position, orientation or number on the side wall 128 with respect to one another. The rails 12 and/or 68 may be used to secure one or more devices 102 in the same or similar manner as noted above.



FIG. 6 also depicts the optional situation where a pair of rails 12 may be located on a partition 134 separating the cargo area from the driver's area. A generic partition 134 is depicted and the partition 134 may of any size, shape or orientation in the vehicle.


In the depicted embodiment, a single pair of rails 12 is shown in the partition 134. While a single pair is shown, the additional pairs may be included at any position, orientation and number. This is true for any of the depicted embodiments. The rails 12 may be attached to the partition 134 as described above to function also as noted above. The rails 12 and/or 68 may be used to secure one or more devices 102 in the same or similar manner as noted above.


Rails 12 may also be attached to the interior surface of the roof, as depicted in FIG. 7, in any number, location and/or orientation. The same figure shows one embodiment of rails 12 being attached to an interior surface of a door of the cargo area.


Rails 12 may also be attached to the floor 130 of the vehicle 116 in any number, orientation and position. Additionally, or alternatively, the organizational applications may be attached to the floor 130, or the walls, and/or the partition 134, and the rails 12 can be attached to the applications as noted above.


Further, versions of organizational applications are depicted in FIGS. 1-7, other applications with rails 12 and/or 68 may be used therewith. For example, the rails 12 and/or 68 may be used with drawers (including floor drawers), cabinets (including file cabinets), ladder racks, bins, consoles, dividers, door kits, door storage devices, tank storage, toolboxes and/or window screens. The rails 12/68 may be used in any number, orientation and/or position with, on and/or in any of these applications including where multiple applications are located in the same vehicle. The rails 12 and/or 68 may be used to secure one or more devices 102 in the same or similar manner as noted above.


From the foregoing, it can be appreciated that a system for selectively but securely storing devices 102 and the like on an organizational application is provided. The system temporarily secures items to an organization application so that the items remain in their placed condition and location until they are intentionally removed therefrom. Namely, the side retention rails 12 secure the container 102 laterally while the end retention rail 68 secures the container 102 front to back (or up and down). This is true regardless of the orientation of the system, such as when it is oriented substantially horizontally, substantially vertically and at any angle in between. And, when it is desired to remove the device 102, the system permits for its quick and easy removal.



FIGS. 1-4 depict one embodiment of an organizational application, such as a shelf. While a shelf of one size and shape, having certain features, is depicted in FIGS. 1-4, other shelves may be used. By way of example only, shelving units may have shelves of other heights, widths, number of shelves and different end panel shapes, sizes and designs including no end panels.
