1. Field of Invention
This invention relates to supporting and displaying construction sheet material and more particularly to an apparatus for supporting and displaying construction sheet material.
2. Description of Related Art
Sheets of construction sheet material are commonly stored and displayed on racks such that sheets are oriented on edge and thus can be displayed and stored in, loaded on, and removed from a stack without being damaged such as by their own weight and such that the floor area that the sheets occupy is minimized. Such racks commonly include a support for supporting the sheets from below and a structure against which the sheets can lean. Loading and unloading of the sheets from these racks is commonly done using a crane or other lifting device via an attachment to the sheets from above.
When sheets of construction material are stacked on these racks, however, only the outermost sheet in each stack is displayed and can be unloaded from the rack. Adding additional upper stacks of sheets above lower stacks allows more than one sheet of construction material to be displayed simultaneously without increasing the floor area that the material occupies; however the increased height of the rack causes instability and can limit access to sheets on the lower stacks. The present invention addresses these problems.
In accordance with one aspect of the invention there is provided an apparatus for supporting and displaying construction sheet material. The apparatus includes a base having first and second parallel spaced apart lower front support areas having distal and proximal end portions respectively. The first and second parallel spaced apart lower front support areas are configured to support at least one sheet of construction sheet material. The apparatus further includes a front upright support connected to the base to extend rearwardly at an angle to the base. The front upright support has third and fourth parallel spaced apart lower front support areas adjacent the proximal end portions of the first and second parallel spaced apart lower front support areas.

It will be appreciated that the front upright support 30 is comprised of first and second front elongated upright channel members 120 and 122 respectively also formed of 4 inch steel channel. Thus, the third and fourth parallel spaced apart lower front support areas 34 and 36 are comprised of channels 124 and 126 into which may similarly be placed cushions formed of wood blocks (not shown) in a manner similar to that shown and described in connection with the first and second parallel spaced apart lower front support areas 14 and 16.

At the proximal end portion 520, the first and second sidewalls 508 and 510 are cut at an angle to have angled surfaces 530 and 532 respectively and such that a tongue portion 534 is formed by part of the web 512 extending past the angled surfaces of the first and second sidewalls. The tongue portion 534 has a length matching a depth of the first front elongated upright channel member 120 such that a rear surface 536 of the tongue portion contacts a surface 538 of the web of the first front elongated upright channel member and such that the tongue portion extends between sidewalls 540 and 542 of the first front elongated upright channel member. The angled surfaces 530 and 532 contact respective edges 544 and 546 of the sidewalls 540 and 542 of the first front elongated upright channel member 120 and are welded thereto. The tongue portion 534 is also welded to the surface 538 of the web of the first front elongated upright channel member 120. The first support member 500 is oriented relative to the first front elongated upright channel member 120 such that the first support member is generally horizontal when the apparatus 10 is in use.
To help support heavy loads such as granite sheets, the first upper front support area 40 is provided with the second support member 502. The second support member 502 is also formed of a length of steel channel having an angled end face 550, a tongue portion 552 and angled wall portions 554 and 556. The angled end face 550 is disposed at an opposite end of the second support member 502 from the tongue portion 552 and the adjacent angled wall portions 554 and 556. In this embodiment the tongue portion 552 and the angled wall portions 554 and 556 are dimensioned such that the tongue portion is received between the sidewalls 540 and 542 of the first front elongated upright channel member 120 to contact the surface 538 of the web thereof and such that the angled wall portions 554 and 556 contact the respective edges 544 and 546 of the first front elongated upright channel member 120 when the angled end face 550 is disposed in the horizontal plane, in contact with a back surface 560 of the web 512 of the first support member 500. The angled end face 550 of the second support member 502 is welded to the back surface 560 of the first support member 500 and the tongue portion 552 and the angled wall portions 554 and 556 are welded to the surface 538 of the web and the respective edges 544 and 546 of the first front elongated upright channel member 120 respectively.
The cushion 516, which in this embodiment is comprised of a first upper front wood member, is thus held captive between the stopper member 504 and the surface 538 of the web of the first front elongated upright channel member 120. The cushion 516 is dimensioned such that a portion 558 thereof extends out of the channel 514 past first and second upper edges 562 and 564 of the first and second sidewalls 508 and 510 to prevent construction sheet material placed on the cushion from touching the first and second sidewalls of the channel.

In the embodiment shown, the first and second front elongated upright channel members 120 and 122 are connected together by first and second crossbraces 140 and 142 which may be held in place by bolts, rivets or welding, for example.
Also in this embodiment, it is contemplated that the apparatus would lean against a vertical surface such as a wall 150 such that respective upper contact points 152 and 154 of the first and second front elongated upright channel members 120 and 122 contact the wall while the base 12 rests on a floor 156 adjacent the wall but spaced apart therefrom due to the angle 32 of the base relative to the first and second front elongated upright channel members 120 and 122 of the front upright support 30. Wall spacers, one of which is shown at 158, may be secured behind the first and second front elongated upright channel members 120 and 122 to secure the apparatus in spaced apart relation to the wall 150 especially when construction sheet material is being loaded onto and removed from the apparatus 10.

In addition, because every sheet of construction sheet material placed on the lower front support areas 14 and 16 is effectively positioned in front of any sheets of construction material placed on the first and second parallel spaced apart upper front support areas 40 and 42, the sheets of construction material on the lower front support areas can be easily accessed and manipulated with a crane, or other similar lifting device, that requires vertical access to its payload, without inducing tipping of the apparatus.
