LOUIS G. BOBROWSKI BY pmw 4 f his ATTORNEYS SHELF BRACKET ASSEMBLY BACKGROUND OF THE INVENTION This invention relates to shelf-supporting brackets, and more particularly, to a shelf-supporting bracket adapted to be secured to support posts which generally extend from floor to ceiling.

As a matter of simple convenience and in keeping with the constantly changing trends in modern design, an increasing need arises for furnishings which are capable of being easily assembled and dismantled for adaptation to variations in room decoration, such as with bookcases, room dividers and open compartment hutches. Heretofore, when shelves have been positioned between upright support posts, it was necessary to first insert hooklike members into vertical uprights, then lower the shelves onto these members and secure onto the other with screws. To keep these screws concealed from above it was necessary to engage and drive them from below, an awkward operation. To rearrange shelves it was necessary to remove these screws and disassociate the shelves from their hook members before the latter could be repositioned, following which the screws would again have to be inserted. Other types of shelf assemblies which do not require the use of tools for assembling have generally proved unsatisfactory in that the assembled unit has generally been unstable and means have not been provided to prevent the shelf from accidentally being shifted.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a shelf assembly which overcomes the above-mentioned disadvantages of the prior art.

It is another object of this invention to provide a durable, sturdy and inexpensive shelf bracket which is capable of accommodating considerable variation in shelf size, bracket positioning and support post spacing and which may be assembled or dismantled with relative ease.

The present invention contemplates the use of aa shelf bracket assembly separable into two parts. One part, the bracket, is T"-shaped and is preattached to the underside of the shelf by the use of screws or the like. The otherpart, the hook plate assembly upon which the shelf bracket is mounted, is adapted to be selectively positioned in the slots of upright standards. Further, this hook plate assembly is channeled to receive and laterally restrain the T"-shaped bracket depending from the shelf. This full lateral restraint permits the positioning of shelves in between pairs of uprights.

The two-part construction allows the shelf to be lifted'bodily upward when it is desired to rearrange the ensemble. It is not necessary to withdraw any screws. When the new positions of the hook plate assemblies have been determined, theshelf, with "T" brackets still attached, is repositioned. It can thus be seen that a great variety of shelf locations can be achieved" without it ever again being necessary to disturb the screw fastenings.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the illustrative embodiment of a shelf bracket arranged according-to the present invention, as shown in FIG. 1-4, there is provided an upright support post 10 of the type which is adapted to extend from floor to ceiling. Secured into a longitudinal slot formed in one side of the support post 10 is an anchor means, here shown as a standard 12 which may be of conventional construction and, accordingly, comprises a plurality of vertically spaced slots 12a, 12b, 12c-12n.

A shelf supporting assembly 14 arranged according to the present invention is adapted to be mounted on the standard 12 with the centerline of the shelf bracket assembly 14 coinciding with the centerline of the support post 10. The shelf bracket assembly 14 comprises a generally 'I-shaped bracket member 16 which includes a stem 18 having a rectangularly shaped slot 20 formed therein for telescopic engagement with a bracket mounting means. The upper portion of the bracket member 16 comprises a web 22 with extending flanges 22a and 22b. The ends of the flanges 22a and 22b have apertures formed therein for receiving corresponding screws 24a and 24b which bolt the bracket member 16 to the underside of a shelf 25.

As best shown in FIG. 3 and 4, the shelf bracket assembly 14-further includes a bracket mounting means or hook plate assembly 26 for attaching the entire shelf bracket assembly 14 to the standard 12. The hook plate assembly 26 comprises a hook plate 27 with lug members 28a, 28b and 280, each lug member having a locking portion 29a--29c, for engaging the segments 1 la, 11b and 11c of the standard 12, and a generally l-sh'aped support member 30 with side channels 30a and 30b and having a longitudinally extending, generally T- shape opening 31 formed therein for receiving the hook plate 27. The hook plate 27 and the support 30 are locked together at their lower extremity by a stake 32 protruding from the support member 30 and integral with it and extending into the hole 33in the hook plate27. With the hookplate 27 and the support member 30 staked together, interference gaps 34a and 34b whose'dimension'is less than the material thickness of the segments 11a and 11b of the standard 12 are provided between the locking portions 294 and 29b of the lug members 28b and 28b, and the support member 30.

As best seen in FIG. 4, to assemble the'shelf supporting bracket'assembly of the present invention, the hook plate 27 is '-inserted through the T"-shaped opening 31 formed in the 33, thus locking the two members together. The extrusion operation is carried out in such a manner thatstake 32 acts to produce a fulcrum about which the hook plate 27 can be bent relative to the support member 30 in the area of opening 31. As shown in FIG. 3, with the hook plate assembly 26 fully assembled, the upper end surface of the hook plate 27 extends slightly above the upper end surface of the support member 30. The hook plate assembly 26 is mounted onto the standard 12 at a predetennined vertical height by inserting the lug members 28a28c through three of the slots 12a-l2c formed in the standard 12 and exerting a downward force on the hook plate assembly 26 causing the locking portions 29a- 29c of the lug members 28a-28c to engage the standard and further causing the hook plate 27 to bend slightly about stake 32. This bending is resisted at point 38 resulting in a secure in-, terlock between the standard 12 and the hook plate assembly 26 when fully seated, and thus accidental shifting, or otherwise dislodging, is resisted.

Thereupon, the shelf 25 is mounted on the shelf supporting bracket 22 by bolting the underside thereof to the flanges 22a and 22b. As shown in FIG. 2, the rectangularly shaped slot formed in the stem 18 of the bracket 16 is aligned with the channels 30a and 30b of the support member 30. The shelf bracket 16 is then lowered onto the support member 30 with the sidewalls of the stem 18 defining the slot 20 in engagement with the channels 300 and 30b of the support member 30. The shelf bracket 16 is lowered until the web 22 of the bracket 16 rests on top of the hook plate 27. In this position, the shelf 25 cannot be accidentally shifted in a horizontal direction, tilted or lowered. When it becomes desirable to reposition the shelving it is only necessary to raise the shelf upward until the slots in the bracket stems are no longer confined within the side channels a and 30b. Thereupon, the hook plate assembly may be moved to a new position, after which the shelf with its T brackets is lowered into engagement with the hook plate assembly.

In an alternate embodiment of a shelf-supporting bracket for the shelf bracket 14, as shown in FIG. 5, the ends of sidewalls of the stem 18 defining the slot 20 may be curled to form lip members and &2. The lip members 40 and 42 snap over the end of the support member 38 to resist upward movement by the shelf-supporting bracket.

In another embodiment of a shelf supporting bracket, as shown in FIG. 6, there is provided a shelf-supporting bracket 50 which includes a slotted stern 52 integral with an obliquely extending web 54 terminated at its opposite ends by a pair of flanges 54a and 54b. The hook plate and support therefor adapted to support the shelf-supporting bracket 50 are of the type described with reference to FIG. 1-5 and, accordingly, need not be described herein. The configuration of the bracket 50 makes it possible to provide for example, a shelf at an angle of variable height upon which to display magazines, and the like, although the shelf bracket of FIG. 6 may also be put to other uses.

Further typical embodiments of a shelf-supporting bracket assembly according to the present invention are shown in FIG. 7-l2. In particular, FIG. 7 shows a one-piece hook plate assembly 60 comprising a plurality of lug members 63a63c, similar to those hereinbefore described and shown in FIG. 3 and 4, integral with a main body portion 62 which includes a rectangularly shaped slot 61 formed therein. The slot 61 in the hook plate assembly 69 is formed to receive the correspondingly shaped, solid stem 64 of a generally T-shaped shelf bracket 65, shown in FIG. 8.

In FIG. 9 a shelf bracket 70 arranged according to the present invention is adapted to receive a plug-in type hook plate assembly 76, as seen in FIG. 10. The shelf bracket 70 is similar to the shelf bracket 16 described in FIG. 1 and 2, accordingly, is generally T"-shaped and includes a stem 71 having a rectangularly shaped opening 72 formed therein into which is inserted the hook plate assembly 76. However, the stem 71 includes a base member 73 which is integral with the flanges thereof and which prevents any vertical movement of the shelf bracket 70 when the hook plate assembly 76 is in position. The hook plate assembly 76 is similar in design and construction to hook to hook plate assembly 26 shown in FIG. 3 and includes a hook plate 79 with lug members 800-801: and a support member 77. The support member 77 of the hook plate assembly 76 is adapted for insertion into the opening 72 of the shelf bracket 70. To this end, the lateral extent of the inside flanges 78a and 78b of the support member is slightly less than the width of opening 72 in the bracket 70 and the width of the outside flange 83 of the support member 77 is slightly greater than the width of the opening 72. Thus, the hook plate assembly 76 is allowed to pass through the opening 72 in the stem 71 until the ridges 82a and 82b of the flange 83 abut the downwardly depending flanges 74a and 74b, respectively, of the bracket stem 71. This arrangement is especially useful when vertical movement of the shelf bracket is impractical for assembling or dismantling the shelf unit, such as for a shelf which is to abut or be positioned near the ceiling of a room.-

As shown in FIG. 11, to insure a tight engagement of the hook plate assembly to the standard, portions of elastomeric material 94 and 95 may be attached to the hook plate at the spaces 92 and 93 between the lug members 91a, 91b, and 91b, 91c. The elastomeric portions 94 and 95 define interference gaps with the locking portions of the lugs. When the lugs are inserted into the slots of the standard, the elastomeric portions 94 and 95 are squeezed against the face of the standard and thereby resist relative motion between the hook plate assembly and the anchor means.

Other alternate spring means may be devised to accomplish the same purpose. In FIG. 12, leaf springs a and 1101) (110a being illustrative) are attached to the hook plate under the lip 111 of the flange 112. These springs act to resist the horizontal movement of the hook plate and to aid the locking action of the hook plate to the anchor means.

Although the invention has been described herein with references to specific embodiments, many modifications and variations therein will readily occur to those skilled in the art. Accordingly, all such variations and modifications are intended to be within the scope of the invention as defined by the following claims.
