Description
The invention relates to apparatus a~apted for attach-ment to a base structure, to provide support for objects.
More particularly, the apparatus accordiny to the present invention relates to a bracket, having fastening means, which permit the bracket to be located, and fixedly maintained at any desired location on a supporting structure. The novel bracket assembly is particularly suitable for providing support ~or shelfs used to store or display objects.
Conventionally, shelfs are supported by angle brackets, the brackets being attached to ths shelf and supporting walls or posts by means of screws, bolts, etc. Other known shelf attach-ment arrangements include clips or fasteners, which are located within slots provided in housings that are themselves mounted to walls or posts.
With conventional systems as briefly discussed above, the manner in which the shelf is mounted renders it inconvenient to effect any adjustment in shelf position. As a practical mat-ter therefore, there is a need for a support system for shelves or the like that can be readily adjusted upon a support structure without the necessity of using tools, or effecting any damage to the supporting structure.
Accordingly, the invention provides fastening apparatus attachable to a base for supporting at least an object, the apparatus, comprises a clip, slideably mounted upon the base in such a manner thak portions of the clip extend at least partially about the base. The second component is an arm pro-vided at its end adjacent the clip with a cam profile, which, upon pivoted movement of the arm from a first substantially vertical~ inoperative position, to a second substantially hor-izontal and operative position, engages with and clamps the apparatus to the base in between the clip and the cam, whereby weigh-t as from an object being supported by the apparatus serves to maintain the apparatus in operative engagement with the base.
In one simple embodiment of the present invention, the clip is substantially U-shaped in plan view, having parallel and vertical front and rear base enveloping sides, the front side having a horizontal length at least one third that of the rear side. The aforementioned first side being provided with a flanged portion extending substantially normal and outwardly thereof, the arm being pivotally attached to the flange portion to operably extend outwardly and parallel therewith.
In a further embodiment of the present invention, the rear side of the clip component is also formed to have a flanged portion extending normally thereto such that the two flanged portions extend in the same direction and lie sub-stantially parallel one with the other.
In a final embodiment of the invention the body ; portion of the clip is substantially circular in plan, the ends of the clip are provided with outwardly extendable, par-allel flanges and the arm is pivotal.ly located between each flange portion to extend radily outwardly therefrom.
The invention will now be described by way of example only, reference being had to the accompanying drawing, in which:
Figure 1 is a perspective view of a first, right handed version of the apparatus according to the invention, with the locking arm in its operative position;
Figure 2 illustrates schematically, the apparatus according to Figure 1, in its operative mode, attached to a verticle right angle support;
Figure 3 illwstrates schematically, a left handed version of the apparatus according to Figure l, attached ~o a square section support, the arm shown in its inoperative posi-tion;
Figure 4 shows, in plan view, an alternative structure according to the invention adapted for attachment to support of this section;
Figure 5 illustrates schematically, a further embod-iment of the pxesent invention, in a form suitable for attachment to a support of circular cross-section and;
Figure 6 is a prospective view of a preferred locking arm.
Referring more specifically to the drawings, where for ease of understanding, like numbers have been utilized to identify like component parts, it can be seen that the apparà tus according to -the present invention comprises two, co-operating components, namely a clip, or body portion 10, and a locking arm 12.
While three separate embodiments of the invention are shown in the drawings, Figure 4 shown in plan view, the apparatus in its simplest configuration. In -this embodiment, the body of the clip 10 is shaped to loosely encompass a rela-tively thin section 13, such as for example, a fibreboard sheet.
The main body of the clip 10 is substantially U-shaped in plan view having substantially parallel, spaced apart front and rear sides lO(a), lO(b). As can be seen from Figure 4, the horizontal length of the front side lO(a) is approximately one third the length of the rear side lO(b). The front side lO(a) is provided with a flanged portion lO(c) which extends normal to side lO(a) and serves to provided ~or the pivoted support of a locking arm 12, the latter bei.ng depicted by Figure 6. As also can be seen from Figure 4, arm 12 is located such that its forward end lO(d) projects into the space lO(b).
~ he embodiment according to Fiyure 4 shows the apparatus in its "locked" configuration. As mentioned above, the body portion lO loosely embraces the support structure 13 such that when the locking arm 12 is in its horizontal opera-tive position, end 12(a) contacts the structure 13 and draws the rear side lO(b) of clip 10 into tight engagement with the structure 13. It will therefore be appreciated that in this, and each subsequently to be described embodiment, the thickness of structure 13 will determine the distance shown by arrow A of Figure 4, of the pivot point 14 from end lO(d) thus ensuring that the apparatus will effectively lock in this operative position.
In a second embodiment of the present invention, as shown in Figures 1-3 the main body portion of clip lO has an additional flanged portion lO(f) which extends at right angles from rear side lO(b), substantially parallel with flanged portion lO(c~. This design, as seen from Figure 2 and 3 serves to facilitate attachment of the apparatus to either a right angle support 13 (Figure 2) or to a square section support 13 (Figure 3).
Under normal circumstances, where the apparatus according to the invention is utilized to support a shelf, right and left handed versions are required. In this regard Figures 1, 2 & 4 show a right handed configuration, where Figure 3 shows a left handed configuration.
With arm 12 raised as shown in Figure 3, it will be appreciated that the apparatus can be readily positioned at any location on the supporting structure 13. When attachment is required to a square sectioned support as shown in Figure 3, the apparatus ma~ be placed in contact with suppork 13, from the side and locked into place. However, in the embodiment accord-~p~
ing to Figure 2, the apparatus must be attached via the top, or conversely, the hottom of the support 13, and slid to its preferred location.
In the embodiment according to Figure 5, the bod~
of the clip 10 is of circular configuration to enable the apparatus to be fastened to, for example, a pipe 13. In this form, adjacent ends of the clip 10 are each provided with out-wardly extending flanges and the arm 12 is pivotally located between the flanges to extend in its locked condition, hori-zontally and outwardly thereof.
Looking now to Figure 6, this figure shows a preferred form of locking arm 12. End 12(a) of arm 12 is formed with two angled surfaces 12(b) and 12(c) which co-operate to form a locking profile or camming surface. The excess of material at 12(d~ allows arm 12 to lock the apparatus to the support structure 13 with no subsequent weight being applied to the arm. As will be appreciated, when the apparatus is used to support an object, such as a shelf, the weight of the object applied to the arm 12 serves to enhance the locking action of end 12(a) with the supporting structure 13. Arm 12 can be pivotally attached to - 20 the main body portion of clip 10 by any preferred means, for example a bolt and nut.(not shown).
Further modifications and alternative embodiments of the invention will be apparent to those skilled in the art in view of the foregoing description. Accordingly, this descrip-tion is to be construed as illustrative only and is for the purpose of teaching those skilled in the art, the manner of carrying out the invention. It is further understood that the form of the presently preferred embodiment. Various changes may be made in the shape, size and general arragement of components, for example equivalent elements may be substituted ~3 6~D~
for those illustrated and described herein, parts may be used independently of the use of other features, all as will be apparent to one skilled in the art after having the benefits of the description of the invention.
