Description
~3~Z35~
Background of the Invention Field of the lnvention This invention relates to a bracket and shelf assembly and is directed more particularly to such an assembly of the "knock~down" type, that is, one that may be readily assembled, disassembled, and reassembled.
Description of the Prior Art It is known in the art to provide bracket members which may be connected to vertical posts or the like, and to which are attached shelf members.
In many instances, the bracket members are provided with hook portions adapted to engage portions of a shelf member to secure the shelf member to the bracket member. In some instances, the bracket member may be provided with one or more moveable ... i 13~;~3~i1 components adapted to lock the shelf member in place. Examples of such assemblies are shown and descr~bed in U.S. Patent Nos.
4,658,968 issued April 21, 1987; 4,658,969 issued April 21, 1987;
and 4,669,692 issued June 2, 1987, all in the name of Arthur R.
Mas~rodicasa. The above prior art assemblies are particularly well adapted for the mounting of wire shelves which are readily engaged by the bracket hook portions.
In the case of solid shelving, it is known to provide shelf members having holes on the underside thereof adapted to receive pins upstanding from bracket members. An example of such an arrangement may be seen in U.S. Patent No. 2,890,012, issued June 9, 1959, in the name of ~acob Deitch.
An object of the present invention is to provide a bracket and shelf assembly in which the bracket and shelf members are provided with button and hole means by which the bracket and shelf members may be connected together.
A further object of the invention is to provide such an assembly in which the button means comprises a shaped button disposed on one component of the assembly and so configured, in conjunction with the other component, to enable the two components to be locked together by a sliding action.
With the above and other objects in view, as will hereinafter appear, a feature of the present invention is the provision of a bracket and shelf assembly comprising first and second bracket members, and a shelf member, each of the bracket members being adapted for attachment to a vertical member and to extend transversely of the vertical member, the first and second bracket members or the shelf member comprising a first component provided with button means extending therefrom, the other component of the first and second bracket members or the shelf member being provided with opening means therein, the opening means being adapted to receive the button means to join the bracket members to the shelf member, the opening means being elongated to permit relative sliding movement between the shelf member and the bracket members, the button means comprising a button having a frusto-conically shaped portion extending from a cylindrically shaped shoulder portion, the smaller diameter portion of the frusto-conically shaped portion being joined to the shoulder portion, the extent of the shoulder portion beyond the first component being less than the thickness of a planar portion of the other component having the opening means therein, the opening means comprising an elongated slot having a first portion of a substantially circular configuration and of a diameter exceeding the large diameter of the button member and a second portion elongated and having a width less than the diameter of the larger diameter of the button and greater than the diameter of the shoulder portion of the button, such that edges of the opening of the slot second portion are wedged between the first component and the walls of the frusto-conical portion of the button as the o~her component is slid along the button means.
The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims. It will be understood that the particular device embodying the invention is shown by way of illustration only and not as a limitation of the invention. The principles and features of this invention may be employed in various and numerous embodiments without departing from the scope of the invention.
Brief Description of the Drawings Reference is made to the accompanying drawings in which is shown an illustrative embodiment of the invention from which its novel features and advantages will be apparent.
In the drawings:
FIG. 1 is an exploded perspective view of one form of bracket and shelf assembly illustrative of an embodiment of the invention;
FIG. 2 is a side elevational view thereof;
FIG. 3 is a sectional view taken along line Ill - 111 of FIG. 2; and FIG. 4 is an enlarged side elevational view of a button portion of the invention.
13(~35~ --Descr~ption of the Preferred Embodiments Referring to the drawings, it will be seen that an illustrative bracket ~nd shelf ~ssembly inc!udes bracket means 2 comprising first and second bracket members 4, 6 compr~sing elongated support portions having base portions 8 and flange portions 10 extending substantially normal to the base portions.
The bracket members 4, ~ are prov~ded with attachment means 12 which facilitate attachment of the bracket members to vertical posts ~not shown) in a manner known in the art.
The attachment means 12 may be formed on the base portion 8 or may, as ~llustrated, be formed on a swivel plate 14 which is pivotally attached to the base portion 8 by a pin 16 and permits angular adjustment of the bracket member in a manner known in the art. A spring-biased set pin 18 is provided to lock the base portion 8 at a selected position.
Attached to the flange portions 10 and upstanding therefrom are button means 20 comprising button members 22. Each button member 22 is provided with a cylindrically-shaped shoulder portion 24 (FIGo 4) which is adjacent the bracket flange portion 10. Extending from the cylindrically-shaped shoulder portion 24 is a frusto-conically shaped portion 26. At the free end of the frusto-conically shaped portion 26 is a cylindrically-shaped cap portion 28, The heighth of the shoulder portion should be less than the thickness of the shelf, to be described hereinbelow. In practice, it has been found that a shoulder portion having a diameter d of .290 inch and a heighth h of .040 inch has performed well.
It has been found that an angle a at which the walls of the frusto-conically shaped portion extend from a base line b defined by the shoulder portion is critical. An angle a of 52 has been found to provide reasonably easy sliding between the bracket and shelf member, to be further described hereinbelow, and at the same time a safe and secure locking engagement. It is believed that an angle a in the range of 47 to 57 would be appropriate.
The frusto-conically shaped portion 26 may be about .080 inch in heighth H ~bove the shoulder portion 24. The cap port~cn 28 may have a diameter D of about .410 ~nch and a heighth h' of about .030 inch. The diameter D (.410 inch) of the cap portion 28 is also the large diameter of the frusto-conically shaped portion 26, and the diameter d of the shoulder portion 24 is also the small diameter of the frusto-conically shaped portion 26.
The bracket members are preferably entirely of metal, but may be formed of a rigid plastic material.
The assembly further includes a shelf means 30 comprising a shelf member 32, preferably constructed of sheet metal or rigid plastic. The shelf member 32 is provided with opening means 34 comprising elongated slots 36. Each of the slots 36 includes a first portion 38 of a substantially circular configuration and of a diameter exceeding the diameter D of said button member cap portion 28 and a second portion 40 elongated and having a width less than the diameter D of the cap portion 28 and greater than the diameter d of the shoulder portion 24 of the button member 22.
In operation, the bracket members 4, 6 are attached to vertical support members (not shown) and, if desired, the angularity of the brackets set by use of the set pin 18 and swivel plate 14. The shelf member 32 is then placed on the flange portions 10 of the bracket members 4, 6 such that the cap portions 28 of the button members 22 enter the first portions 38 of the slots 36. The shelf member is then pulled to the left, as viewed in FIGS. 1 and 2, such that the second portions 40 of the slots 36 slide by the button members 22 and, more specifically, the edges of the slot second portions 40 engage the walls of the frusto-conically shaped portion 26 of the button members 22 (FIG.
3).
The shelf 32 is of a thickness exceeding the heighth h of the shoulder portion 24 of the button members 22. Accordingly, the slot edges impinge upon the walls of the button portion 26 and are forced thereby into tighter engagement with the flange portions 10 of the bracket members, as illustrated in FIG. 3. Thus, the shelf member is wedged into a secure frictional engagement with bracket means 2.
~3(~Z3S~
lt is to be understood that the present invention is by no means limited to the particular construction herein disclosed and/or shown in the drawings, but also comprises any modifications or equivalents within the scope of the disclosure. For example, while the invention has been illustrated with the button means on the bracket members and the openings in the shelf member, it will be apparent that the assembly could employ openings in the bracket means and downwardly extending button means on the underside of the shelf member. In instances in which a smooth shelf surface is required, without buttons protruding into the storage area, such reversal of the connecting elements is preferred. Thus, a first of either of the basic components, that is, either the shelf or the bracket means, may be provided with the button means and the other of the shelf or the bracket means may comprise a second component having the complemental opening means.

Attached to the flange portions 10 and upstanding therefrom are button means 20 comprising button members 22. Each button member 22 is provided with a cylindrically-shaped shoulder portion 24 (FIGo 4) which is adjacent the bracket flange portion 10. Extending from the cylindrically-shaped shoulder portion 24 is a frusto-conically shaped portion 26. At the free end of the frusto-conically shaped portion 26 is a cylindrically-shaped cap portion 28, The heighth of the shoulder portion should be less than the thickness of the shelf, to be described hereinbelow.
