BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to mounting fixtures and more particularly to a slotwall mounting assembly having a number of vertically spaced, elongated, horizontally extending rails that define slots or channels between the rails adapted to receive one or more mounting brackets. Walls made from such rails are generally known or referred to as “slotwalls.”
2. Description of the Related Art
Slotwalls are used in a wide variety of applications for storing and displaying products, tools, and accessories. Examples of the industries in which slotwalls are used include retail display, closet storage, garage storage, and office furniture. As is well known, a slotwall is a wall panel formed from metal, pressed board, plastic or other suitable material having a plurality of regularly spaced, horizontally extending rails. Each rail includes an upper surface and a lower surface, and a lip extending from one or both of the surfaces to form channels of L- shaped or T-shaped cross section between the rails. Various different accessories such as brackets, shelves, baskets, and the like are available which are specially designed for fitting into the grooves of the slotwall so that items can be conveniently hung or otherwise supported thereon.
A typical mounting bracket for a slotwall includes a flat body and some type of cantilever element for fitting into one of the grooves. The body generally lies flat against the slotwall, so that accessories such as hooks, racks, and shelves can be attached to its outer face. The cantilever element is generally an L-shaped mounting flange that extends perpendicularly from an upper portion of the body and then forms a corner that turns upwards. The L-shaped mounting flange fits into a slotwall channel such that a horizontal portion sits on the upper edge of a first horizontal rail, and a vertical portion is positioned behind a downwardly extending lip of the horizontal rail immediately above.
The major disadvantage of conventional slotwall mounting brackets is how easy they can be dislodged from the slotwall after installation. While the mounting brackets remain in position well under load, they are easily moved and can be dislodged from the slot when subjected to upward forces. The same rotation action that easily allows the mounting brackets to be easily installed in the slotwall also allows the mounting brackets to rotate away from the wall when an upward force is applied to the end of the mounting bracket.
U.S. Pat. No. 7,228,977 owned by the Whirlpool Corporation discloses a complicated form of a slotwall mounting bracket for solving the accidental dislodging of the mounting brackets. A hanger bracket is described which can be mounted on the panel and is shown with a hook device attached to the hanger bracket. The hanger bracket includes a central support portion, a generally “J” shaped hook extending from an upper edge of support portion, and a generally “J” shaped hook extending from a lower and opposite edge of the support portion. The generally “J” shaped hooks each include a first leg extending generally perpendicular from the edge of support portion and a second leg extending downwardly from the distal end of the first leg yet generally parallel to support portion. Thus, the hanger bracket has two downward opening “J” shaped hooks on opposite edges of the support portion. The hanger bracket also includes a spring arm extending from the upper edge of the support portion and splits the upper generally “J” shaped hook into two portions. The spring arm extends upwardly in direction opposite that of the legs.
The generally “J” shaped hooks are of a height to be received within the slots of the slotwall so that the downwardly extending legs are positioned into and deep behind the lips of the T-shaped slot formed in the wall. The hanger bracket is then translated downwardly so that the downwardly extending legs are positioned behind the lips of the T-slot and the first leg contacts the upper edge of a generally “T” shaped slat. The legs bear against the underside of the lower adjacent half slats in the undercuts and are biased against the slat by the spring arm. The spring arm is positioned behind the upper adjacent slat in the undercut and engages the back of the slat to leverage the lower “J” shaped hook toward the front of the slotwall. Thus, the hanger bracket transfers a load on a hanging device through the hanger bracket to the slotwall panel by the contact of legs on the edge of the slats, the contact of legs against the inside edge of the slats and the force of spring arm pushing the legs against the edges of the slats.
A substantial difference exists between the hanger bracket disclosed in the '977 patent and that of the invention described below. Most notably is the fact that the '977 patent utilizes two downwardly depending “J” shaped hooks that are received over the upper edges of the T-shaped slats substantially simultaneously, and sliding over the slat edges, to hold the bracket in position. The spring arm positioned behind the lower lip of the upper slat also requires the user to exert force and keep the lower “J” shaped hook within the T-shaped slot during installation. The bias applied by the spring then urges the lower “J” shaped hook into compression with the lower slotwall slat to stay in position.
Another solution to the inadvertent dislodgement of slotwall mounting brackets is disclosed in U.S. Pat. No. 4,507,753 assigned to Ready Metal Manufacturing. Described therein with reference toFIGS. 10,14 and15, a hanger is attached by welding to a pair of opposed grooves in the panel. The upper extremity of the plate is bent to provide an angular seating member engageable in an upper groove betweenadjacent slats20. To the lower part of the plate is slideably attached a locking plate having an offset rectangular end portion that is received in a lower groove. The slideable plate has side flanges embracing side edges of plate and is slotted. The plate may be slotted to permit passage of a rivet or set screw to engage the sliding plate. To attach this hanger to the slotwall, a flange is disposed in an upper groove and the angular portion is slid down into position in the lower groove to secure the hanger in a selected position on the wall.
A slight variation of the '753 invention is described with reference to FIGS.10 and16-18. There the hanger is engageable in the upper and lower grooves adjacent a slat. The slideable plate which is slotted has no embracing side flanges as in the above described embodiment. The plate at its lower extremity has rearwardly bent flanges for seating in the lower groove. The hanger can be dislodged by simply sliding the lower extremity upward so that the rearwardly bent flanges are lifted up from the behind the slat flange.
A major disadvantage associated with both embodiments disclosed in the 753 patent is that multiple parts and assembly are required. Moreover, the operation of installing and removing the slotwall mounting brackets is necessarily a two-handed operation. The increase number of parts, the manual assembly of the components, and the two handed operation for installing and removing the brackets makes them more expensive to manufacture, more difficult to handle.
There has been a long felt vet unresolved need to a slotwall mounting bracket that can be easily attached to a slotwall rail using a single hand yet once attached is not easily dislodged by a casually applied upward force commonly associated with passers-by. In addition, the invention described below is easily removed from the slotwall rail with the application of a specific force to quickly and easily move the slotwall mounting bracket to a new location.
SUMMARY OF THE INVENTIONThe aforementioned problems are overcome by the present invention, wherein a slotwall mounting bracket assembly is provided with a locking flange that snap-fits onto an edge of a slotwall rail to prevent the mounting bracket from rotating away from the slotwall and hold the mounting bracket in place on the slotwall.
In one embodiment, the slotwall mounting bracket includes a generally planar body, an upper L-shaped mounting flange, and a lower locking flange. The mounting flange extends from the body and hooks into a first slotwall groove, supporting the mounting bracket on the upper surface of a horizontal rail on the slotwall. The locking flange extends from the body and snap-fits over the lip extending downwardly at the bottom surface of the horizontal rail, preventing the mounting bracket from inadvertently rotating upward and off from the slotwall.
In a more specific embodiment, the locking flange includes a first portion, a second portion, and a third portion. The first portion extends generally perpendicularly from the body. The second portion extends at an angle upwardly from the first portion such that the second portion fits around the downwardly extending lip to hold the mounting bracket on the slotwall. The third portion extends from the second portion to provide a ramp at the leading edge of the locking flange to lever the locking flange over the lip and lock over the lip in snap-fit engagement. One or more of the portions may define one or more voids to increase the flexibility of the locking flange relative to the body and reduce the effort required to snap fit the locking flange about the lip. The cutout also provides a pry point to aid in removal of the mounting bracket from the slotwall.
In a further embodiment, the body of the mounting bracket includes a rear surface facing the slotwall and a front surface opposite the rear surface. The front surface includes one or more protrusions that provide a surface for welding an accessory mount to the mounting bracket. The accessory mount enables a variety of conventional accessories to be attached to and supported by the mounting bracket, avoiding the purchase or remanufacturing of modified slotwall accessories, making the present invention easily adaptable to existing slotwall accessories.
These and other objects, advantages, and features of the invention will be readily understood and appreciated by reference to the detailed description of the current embodiment and the drawings.

DETAILED DESCRIPTION OF THE INVENTIONFor purposes of the following description, the terms “upper,” “lower,” “left,” “rear,” “front,” “vertical,” “horizontal” and derivatives of such terms shall relate to the invention as oriented inFIG. 12. However, it is to be understood that the invention may assume various alternative orientations and configuration, except where expressly specified to the contrary. It is also to be understood that the devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the inventive concepts of this invention. Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting unless expressly stated otherwise.
I. Overview
A slotwall mounting bracket in accordance with a preferred embodiment of the present invention is shown inFIGS. 1 and 3 generally designated10. The mounting bracket includes a generallyplanar body12, a mountingflange14, and a lockingflange16. In operation, the mountingflange14 is inserted into a first slotwall groove18 (shown inFIG. 11), and rotated in position so it hangs on theupper surface22 of ahorizontal rail24 in theslotwall20. The lockingflange16 is received over thelower edge26 of therail24 in snap-fit engagement. The force exerted by the snap-fit engagement of the lockingflange16 over thelower edge26 of therail24 is sufficient to prevent inadvertent dislodgment of theslotwall mounting bracket10 from theslotwall groove18.
II. Structure
As noted above, theslotwall mounting bracket10 is mounted on theslotwall20.Slotwall20 is widely known and therefore will not be discussed in detail here. But in brief, theslotwall20 is generally made from pressed board such as medium density fiberboard (MDF), or from plastic or extruded metal such as steel or aluminum.FIGS. 11 and 12 show theslotwall20. In the illustrated embodiment, theslotwall20 includes a plurality of vertically spaced horizontal rails24. Eachslotwall rail24 generally includes anupper surface22, alower surface28, and alip26 extending downwardly from thelower surface28. Therails24 each define aheight13 from theupper surface22 to thelower surface28. A plurality ofslotwall grooves18 having an L-shaped cross-section are formed between the horizontal rails24. In an alternative embodiment (not shown), therails24 may include a lip extending from both the upper and lower surface, such that the grooves each have a T-shaped cross section. As illustrated, the downwardly extendinglip26 includes a roundedtip30.
As shown inFIGS. 3-7, the mounting bracket includes abody12, a mountingflange14, and a lockingflange16. Thebody12 is generally planar and includes afront surface34,rear surface36,top edge38, andbottom edge40. Thebody12 includes aheight15 between the top38 and bottom40 edges that is approximately equal to theheight13 of ahorizontal rail24 on theslotwall20. In the illustrated embodiment, thefront surface34 includes a plurality of protrusions in the form ofribs44 that extend transversely across thebody12. Theribs44 add strength to thebody12 and also provide a welding surface for attaching an accessory mount, such as mounting forks50 (shown inFIG. 10) a hook, a bracket, or a variety of alternatives. Anadditional rib45 may extend around the periphery of thefront surface34 for added strength. The mountingflange14 extends from the top edge of thebody12 in a generally perpendicular direction. Mounting flanges are widely known, and are typically L-shaped for extending into aslotwall groove18. As shown inFIG. 3, the mountingflange14 includes afirst member52 that extends from thebody12. Asecond member54 extends upwardly from thefirst member52 approximately perpendicular to thefirst member52. Thesecond member54 may include acurved end56 that angles back toward thebody12.
As shown, the lockingflange16 extends in a generally perpendicular direction from thebottom edge40 of thebody12; however, the flange may extend at a variety of different directions. The distance between the mountingflange14 and the lockingflange16 is approximately the same as theheight13 of each of thehorizontal rails24 of theslotwall20. As a result, in the case where theheight15 of the body is greater than the height of therail24, the lockingflange16 may extend from thebody12 at a location inward of thebottom edge40. The lockingflange16 is generally shaped to correspond to the roundedtip30 on the downwardly extendinglip26 of ahorizontal rail24, such that the lockingflange16 can snap fit about the roundedtip30 when the mountingbracket10 is rotated into place. As illustrated, the lockingflange16 includes afirst portion60 extending from thebody12, and asecond portion62 that angles upwardly from thefirst portion60. Athird portion64 may extend from thesecond portion62 and curve downwardly from thesecond portion62 to form a ramp for the leading edge of the lockingflange16. In addition, as shown inFIG. 9, the lockingflange16 may define acutout66 to increase the flexibility of the lockingflange16 relative to thebody12. As illustrated, thecutout66 is located in thefirst portion60; however it may be located anywhere in the lockingflange16.
III. Operation
In operation, the present invention is mountable ontoconventional slotwall20 in a few simple steps, while accommodating a variety of accessories and preventing unwanted rotation and movement. Installation of the present invention requires first hanging the mountingflange14 on theslotwall20, and then snap-fitting the lockingflange16 to the slotwall.
The first step of installing a slotwall mounting bracket in accordance with the present invention is hanging the mountingflange14 on theslotwall20. To begin, a desired height and location on theslotwall20 are chosen. The mountingbracket10 is then held manually such that thebody12 is perpendicular to theslotwall20, with thesecond member54 of the mountingflange14 aligned with the chosenhorizontal slotwall groove18. The mountingflange14 is then inserted in to thegroove18 and is rotated until thesecond member54 extends upwardly behind the downwardly extendinglip26 of afirst slotwall rail24 and thefirst member52 is supported on theupper surface22 of a secondhorizontal slotwall rail24.FIG. 11 shows the mountingbracket10 in a partially installed position in phantom lines. In the final position, shown in solid lines inFIG. 11 and inFIG. 12, therear surface36 of the body bears against theslotwall20.
As the mountingbracket10 is manually rotated into the final position, the lockingflange16 approaches the roundedtip30 of the downwardly extendinglip26 of the secondhorizontal rail24. The ramped leadingedge64 of the lockingflange16 engages the roundedtip30 and slides along the roundedtip30 to lever thesecond portion62 of the locking flange on to a portion of the roundedtip30 and lock the mountingbracket10 in place on theslotwall20. As the lockingflange16 engages the downwardly extendinglip26 and is slid over the roundedtip30, the lockingflange16 is levered over the edge and flexes slightly outward, and then returns or “snaps” back into place securely around the roundedtip30. With the mountingbracket10 in place and the lockingflange16 in snap-fit engagement with the downwardly extendinglip26, the mountingbracket10 is securely attached to theslotwall20 and is not likely to be inadvertently dislodged by an inadvertent upward force. The locked position of the mountingbracket20 also now permits an item to be suspended or hung from the mounting accessory or hanger extending from thefront surface34 of the mountingbracket body12.
Removal of theslotwall mounting bracket10 is essentially the opposite of installation. First, thefront surface34 is pulled away fromrail24 such that the downwardly extendinglip26 of the lockingflange16 is wedged over thelip30 and become disengaged. To assist, thecutout66 may receive a tool to assist in levering the locking flange off from the lip. With the lockingflange16 disengaged, the mountingbracket10 may be rotated upwardly about the mountingflange14 so that the mountingflange14 may be removed from theslotwall20. When removing the mountingbracket10, the bottom40 of thebody12 is pulled away from theslotwall20 so that the mountingflange14 rotates about the downwardly extendinglip26 of the first or upperhorizontal rail24. Rotation is complete when thebody12 is again perpendicular to theslotwall20, and the mountingbracket10 can then be removed from thegroove18.
In summary, once a desired height and location for placement of the mountingbracket10 is determined, the mountingbracket10 can be attached to theslotwall20 to hang the mountingbracket10 and any accessory such that they will not be knocked off of theslotwall20.
The above description is that of a current embodiment of the invention. Various alterations and changes can be made without departing from the spirit and broader aspects of the invention as defined in the appended claims, which are to be interpreted in accordance with the principles of patent law including the doctrine of equivalents. Any reference to claim elements in the singular, for example, using the articles “a,” “an,” “the” or “said,” is not to be construed as limiting the element to the singular.
