Mounting system
A mounting system incorporates a supporting panel (1) and a mount (4). The supporting panel incorporates cavities (2, 3) having an aperture (10) in a front face of the panel. The cavity widens from the aperture to a hook receiving portion (11) having upper and lower surfaces, with at least the upper surface incorporating a recess (39) and the lower surface incorporating an inclined bearing surface (38). In use the hook is arranged to be located in the hook receiving portion (11), with a distal portion (15B) of the hook being located within the aperture and rotated so that the hook passes the aperture and locates within the hook receiving portion. Further, to resist withdrawal of the hook from the cavity, the distal and proximal portions are arranged to abut respective ones of the upper and lower surfaces and to become wedged between those surfaces.
The present invention relates to a mounting system. The mounting system is particularly, but not exclusively, suitable for mounting of shelving.
Throughout the specification, the invention is described and defined with reference to the orientation for use where the mounting system has a supporting panel which is disposed in a vertical orientation. This, however, should not be construed as limiting the invention to this orientation as the mounting system may be used in different orientations. Accordingly, reference to a particular orientation, such as “upper” and “lower” is to be construed to encompass these other orientations.
BACKGROUND TO THE INVENTIONOne mounting system on the market is known as SLATWALL. This mounting system has a supporting panel, which is usually 2400 mm wide by 1200 mm high by 18 mm thick. The supporting panel is formed of custom wood which has cut out of it seven horizontal slots. Each slot has a rectangular entrance portion extending the length of the panel. Each entrance portion is about 10 mm high and 4 mm deep. The entrance portion then opens out to a larger interior rectangular cavity which is about 30 mm high and 10 mm deep and arranged symmetrically relative to the aperture so equal parts of the interior rectangular cavity extend above and below the aperture. Seven aluminium extrusions are received within respective ones of the seven slots in order to reinforce the slots. Brackets are then mounted within the slot in order to support shelving.
One problem with this existing system is that when the brackets are supporting shelving, the weight on them tends to cause the bracket to bear on the extrusion in the region above the aperture. In turn, this tends to cause the reinforcing extrusion to bear on the portion of the supporting panel immediately above the entrance portion. This portion of the supporting panel is 10 mm long and only 4 mm thick and is at right angles to the roof of the interior rectangular cavity. Accordingly, force applied to this portion of the panel tends to cause the custom wood to break in the vicinity of where it joins the roof of the interior cavity and results in the reinforcing member and bracket pulling out of the supporting panel. A further problem is that the size of the rectangular cavity is substantial relative to the size of the panel which can lead to the supporting panel bending or bowing. Further, the size of the openings are so big that they detract from the appearance of the mounting system.
Accordingly, it would be advantageous to provide a mounting system which addresses at least one of these problems.
SUMMARY OF THE INVENTIONAccordingly in a first aspect, the present invention provides a mounting system having:
a supporting panel having a cavity therein, the cavity having an aperture in a front face of the supporting panel, the cavity widening from the aperture to a hook receiving portion having upper and lower surfaces; and
a mount having a hook, the hook incorporating a distal and proximal portion and being shaped so that the mount may be fixed to the panel by locating the distal portion within the aperture and rotating the mount so that the hook passes the aperture and locates within the hook receiving portion, wherein to resist withdrawal of the hook from the cavity under the influence of a turning moment induced on the hook by a load applied to the mount, the distal and proximal portions are arranged to abut respective ones of the upper and lower surfaces and to become wedged between those surfaces as the hook moves across at least one of those surfaces under the influence of the turning moment.
In a second aspect, the present invention provides a mounting system having:
a supporting panel having a cavity therein, the cavity having an aperture in a front face of said supporting panel, the cavity widening from the aperture to a hook receiving portion; and
a mount having a hook, the hook being shaped so that the mount may be fixed to the panel by locating a distal portion within the aperture and rotating the mount so that the hook passes the aperture and locates within the hook receiving portion with the distal portion abutting an upper surface of the cavity, wherein to resist withdrawal of the hook by the cavity on applying a load to the mount, the distal portion is caused to be forced into engagement with the upper surface of the cavity.
In a preferred form of this aspect, the hook includes a proximal portion which is arranged to abut a lower surface of the cavity, wherein in resisting withdrawal of the hook from the cavity, the hook becomes wedged between the roof and the lower surface.
A mounting system according to these aspects of the present invention have substantial practical benefits. By having an arrangement where the hook becomes wedged between the upper and lower surfaces to resist its removal from the cavity, the hook is forced into compression causing the reaction loading to be distributed across regions of the supporting panel disposed both above and below the cavity. This substantially reduces the localised loading effect which was present in the previous systems.
The inventor has found that by using the wedging action, it is possible to produce the supporting panel from custom wood or even particle board for use in retail shop fittings without requiring the need for any reinforcing extrusion provided within the cavity. This not only substantially reduces the costs of manufacture but also allows much more flexible design of the mounting system. For example, the panels may be curved. In addition, depending on any loading requirements, the supporting material may also be made from different materials such as corrugated cardboard or the like.
In one embodiment, on insertion of the hook into the cavity, the distal and proximal portions are arranged to abut the upper and lower surfaces so as to place the hook in compression. This arrangement prestresses the hook and thereby limits the play in the mount. It also provides a better “feel” as the mount is placed in register within the hook receiving portion of the supporting panel.
In one form, the hook receiving portion of the cavity is shaped so that the lower surface extends upwardly in a direction towards the aperture. The orientation of this surface provides at least part of the wedging action that is induced on the hook as it resists being withdrawn under the influence of the applied loading on the mount.
In one form, the hook is arranged to pivot about its distal portion on locating the hook within the hook receiving portion. In a particular embodiment, the upper surface incorporates a recess that is configured to receive the distal portion of the hook. In this arrangement, an outer surface of the distal portion engages a complementary shaped portion of the recess wall so as to facilitate pivoting of the hook about its distal portion when located in that recess.
In a particular embodiment, the hook is formed by a pair of arcuate portions which are joined together to define a generally v-shaped hook. One of the pair of arcuate portions includes the distal portion of the hook, and the other arcuate portion includes the proximal portion.
In a particular embodiment, an outer surface of one of the arcuate portions has a constant radius of curvature having the axis of radius disposed in the other arcuate portion. In a particular arrangement, the axis of the constant radius of curvature of the other arcuate portion (which includes the proximal portion) is arranged to be the point at which the hook pivots about its distal portion in installing the hook in the cavity. Furthermore, in a particular embodiment, the lower surface is also arcuate having a constant radius of curvature which is complementary to the outer surface of the arcuate portions.
The geometry of the above arrangement is such that installation of the hook is controlled.
Preferably, at its highest, the cavity is between 1.5 and 3 times as high as at the aperture and most preferably about 2.5 times as high.
Preferably, the cavity is formed by an elongate slot which defines an extended hook receiving portion adapted to receive a plurality of hooks of respective ones of a plurality of mounts.
Preferably, the panel has a plurality of substantially parallel elongate slots.
Alternatively, the mounting system includes a plurality of cavities spaced horizontally apart from one another when the panel is located in a substantially vertical plane.
Preferably, the height of the aperture is less than three times the thickness of the hook.
Preferably, the supporting panel has a plurality of rows of spaced apart cavities.
Preferably, the mount is part of a bracket. Preferably, the bracket includes a flange which locates flush against the support surface. In use on loading the bracket, it causes a turning moment to be induced about the lower edge of the flange. This turning moment is resisted by the hook in the cavity engaging the cavity walls.
In one embodiment described above, the hook is formed by a pair of arcuate portions which are joined together to define a generally v-shaped hook. Preferably, the points defining the ends of the arcuate portions are disposed relative to one another such that if the points were joined by straight lines, the lines would define a substantially equilateral triangle.
Preferably, the hook receiving portion is formed in part by the cavity having a rear surface opposite the aperture, the rear surface having a complementary shape to the one of the arcuate portions which provides the hook end.
In a further aspect, the present invention relates to a mounting system having:
a supporting panel having a cavity therein, the cavity having an aperture in a front face of the supporting panel, the cavity widening from the aperture to a hook receiving portion having an upper surface incorporating a recess disposed inwardly from the aperture, and a lower surface which extends upwardly in a direction toward the aperture; and
a mount having a hook, the hook incorporating a distal and proximal portions and being shaped so that the mount may be fixed to the panel by locating the distal portion within the aperture so that it locates within the recess and thereafter rotates about its distal portion to be fully received within the cavity, wherein the recess has a wall surface that is shaped to complement an outer surface of the distal portion so that the hook is able to pivot about its distal portion when locating the hook in the hook receiving portion.
In a preferred form, the lower surface is arcuate having a constant radius of curvature having an axis substantially coincident with the axis about which the distal portion pivots.
In a preferred form, the proximal portion of the hook incorporates an arcuate outer surface which has a constant radius of curvature having its axis disposed at the distal portion.
In a further aspect, the invention relates to a supporting panel for use in a mounting system as described in any form above. In yet a further aspect the invention relates to a mount for use in a mounting system as disclosed in any form above.
In yet a further aspect the invention relates to a supporting panel for a mounting system, the supporting panel incorporating a cavity arranged to receive a hook for a mount, the cavity having an aperture in a front face of the supporting panel, and widening from the aperture to a hook receiving portion, wherein the upper surface of the cavity includes a recess spaced from the aperture, and a lower surface of the cavity incorporates an arcuate surface having a constant radius of curvature having its axis disposed generally in the recess.
In yet a further aspect the invention relates to a mount for a mounting system, the mount having a hook formed by a pair of arcuate portions which define a generally v-shaped hook, wherein one of the pair of arcuate portions includes a distal portion of the hook, and the other arcuate portion includes a proximal portion of the hook, the proximal portion having an outer surface having a constant radius of curvature having its axis disposed at the distal portion.
BRIEF DESCRIPTION OF THE INVENTIONIt is convenient to hereinafter describe the embodiments of the present invention with reference to the accompanying drawings. It is to be appreciated that the particularity of the drawings and the related description is to be understood as not superseding the generality of the preceding broad description:
In the drawings:
A prior art mounting system which is known as SLATWALL and is available from AUSTRALIAN SLATWALL INDUSTRIES PTY LTD. The prior art mounting system has a supporting panel which has seven horizontal slots therein. Each slot extends the length of the panel.
In use, a mount 104 of a bracket is placed within the slot. In use the mount will generally support a bracket which in turn will support shelving. When force is applied to the mount 104 by weight on the bracket it tends to cause the end 106 of the mount to bear on the portion 107 of the reinforcing extrusion 103 located above the aperture 101. This in turn causes the reinforcing portion to bear on the flange 105 located above the aperture 101. This, in turn tends to cause the flange to break and the reinforcing extrusion 103 and bracket to pull out of the supporting panel.
Further, the relative size of each of the slots consisting of aperture 101 and rectangular hole 102 is such that it tends to weaken the supporting panel and causing it to bend or bow.

Referring now to
The mount 4 forms part of a bracket as shown in
Referring to
The ends of the arcuate portions 15 are disposed relative to one another such that if they were joined by lines they would form a substantially equilateral triangle. In addition, the outer surface 34 of the arcuate portion 9A and the outer surface 35 of the second arcuate portion 9B, have a constant radius of curvature. Furthermore, the axis of the radius of curvature of the surface 35 lies at the distal portion 15B whereas the axis of curvature of the outer surface 34 of the arcuate portion 9A is in the vicinity of the juncture 15C between the second arcuate portion 9B and the flange 6.
In the illustrated embodiment, each of the surfaces 36, 37 include arcuate portions 38 which are inclined inwardly towards the aperture 10. Each of the upper and lower surfaces 36, 37 also includes a recessed portion 39. These recessed portions include a shoulder portion 40 which faces away from the aperture 10 and a curved bridging portion 41 which extends from the respective shoulder portions to the rear surface 13 of the cavity.
The cavity 2 is shaped to receive and allow the hook 5 to pass the aperture 10 of the cavity and locate within the hook receiving portion 11 of the cavity while also allowing the aperture 10 to be relatively narrow. For example, where the hook arcuate portions 9 are approximately 1.5 mm thick it is possible to pass the hook through an aperture which is about 4 mm high. Thus, the height of the aperture can be less than three times the thickness of the hook.
The process of locating the hook 5 within the cavity 2 is best illustrated in FIGS. 8 to 10.
Turning firstly to
A particular feature of the above arrangement is that this guided action of location of the hook within the cavity 11 is such that it inhibits the hook damaging the outer edges 42 of the aperture 10. In addition, the arcuate portions 9A are designed to be slightly oversized so that when the hook 5 is located within the hook receiving portion 11, it is caused to be compressed between the bearing surface 38 and the bridging surface 41. This arrangement prestresses the hook and thereby limits the play in the mount. It also provides a better feel as the mount is placed in register with the cavity receiving portion of the supporting panel.
In use, when weight is applied to the bracket 8, it tends to induce a turning moment as the bracket tries to pivot about the bottom 43 of the flange 46 (see
This induced turning moment is resisted by the engagement of the hook 5 within the hook receiving portion 11. Specifically, this turning moment is resisted by the engagement of the hook end 15B with the bridging portion 41 and by engagement of the outer surface 35 with the bearing surface 38. Because of the geometry of both the cavity and the hook 5, the induced turning moment 9 causes the arcuate portion 9B to try to ride over the surface 38. This causes the end 15B of the hook to be driven into tighter engagement with the roof portion 41 thereby placing the hook 5 in compression and distributing the reactive force on both a portion 1C of the panel disposed above the slot and a lower portion 1B of the supporting panel 1 disposed below the slot. As a result, these reactive forces are distributed more evenly across the supporting panel thereby minimising concentration of stresses in the panel 1.
By being able to distribute the load across both the regions 1C and 1D, the prospects of the panel breaking is greatly reduced. As such, the inventor has found that when the supporting panels are made from custom wood using the dimensions of the preferred embodiment they have sufficient strength for most retail applications without requiring the need for any separate reinforcing extrusion as in the prior art.
The following are the results of tests conducted by the applicant. In the test conditions two brackets were placed at 600 mm centres and inserted in the cavity on 18 mm MDF (custom wood). A shelf was located over the brackets and a weight W was applied to the shelf and evenly distributed over that shelf.
Different brackets were tested with A being the length of bracket, B being the length of back-plate, C the width of the back-plate and W being the vertical load of near breaking point.
The test results show that the mounting system is able to accommodate loading, which is clearly beyond that usually experienced in retail applications.
A variation on the configuration of the cavity is illustrated in
The advantage of providing the arrangement in
It will be apparent to persons skilled in the art that various modifications may be made to the present invention without departing from the scope of the invention. One such alternate embodiment is illustrated in
It will be apparent to persons skilled in the art that the upper portion 32 in this case is angled and hence that, the bearing surface on which the hook end bears does not need to be perpendicular to the front face 16 of the board. As the hook receiving portion widens gradually from the aperture 20, it means that the force required to cause failure of the panel must be much more substantial than in the prior art even if some of the force applied by the end of hook 25 is applied in a direction towards the front face 16 of the board 1.
Other variations will be apparent to persons skilled in the art, for example, the hook of each mount does not need to be continuous and could be formed by a plurality of spaced hook portions. Further, while it is preferred that the aperture be kept as narrow, in some applications a narrow aperture will not be essential and the ratio of the height of the aperture to the highest portion of the cavity can be in the range of approximately 1.4-4:1 but more preferably in the range of 1.5-3:1.
It will be apparent to persons skilled in the art that they may make various variations to the mounting systems of the first and second embodiments without departing from the scope of the present invention. Such variations are considered to be within the scope of the invention described herein.
