ABSTRACT:
BACKGROUND OF THE INVENTION
Corner protectors are well known to the art. Essentially they are protective structures or bumpers adhered or mechanically fastened to walls of high traffic areas to protect walls from being damaged by impacts from rolling carts, wheeled equipment, and the like. Exemplary prior art corner protector assemblies are shown in U.S. Pat. Nos. 5,363,617; 4,903,449; 4,706,426; and 4,196,552.
SUMMARY OF THE PRESENT INVENTION
The present invention is directed to improvements in existing designs. The new corner protector assembly provides for the use of decorative wood panels as a major component of the corner protector assembly. In addition, the design of the invention provides a flush appearance and uniquely combines the aesthetics of wood with impact absorbing characteristics of vinyl. The entire new assembly may be easily and efficiently manufactured employing simple aluminum extrusion techniques, simple vinyl co-extrusion techniques, and simple woodworking techniques. Importantly, installation of the entire new assembly, including wall-mounted aluminum extruded retaining member and wood bumper panels which are slidingly assembled at the corner into the retaining member, is quickly and easily completed by snapping a vinyl cushioning member into the retaining member between the wood bumper panels. Should repair or replacement of the wood panels become necessary, the new design permits quick and easy removal of the panels by simply removing the snap-in cushioning member and sliding the panels out.
More specifically, the new and improved decorative corner guard assembly includes decorative wood panels secured within an elongated extruded aluminum retaining member which is mounted in a recess formed in intersecting walls at a high traffic corner to be protected from impacts by carts or other wheeled equipment. The retaining member is anchored to the intersecting walls of the corner by a suitable adhesive or mechanical fasteners.
In a preferred embodiment of the invention, the retaining member includes locating projections and end wall portions which locate and receive decorative wood bumper panels by lateral sliding engagement and support the panels proximate to the corner. A projecting locking bar is formed at the apex of the retaining member between the bumper panel retaining sections. A resilient co-extruded vinyl locking rail having a hard inner locking clip portion and a softer outer cushioning portion is quickly and easily snapped over the locking bar to complete the assembly. The vinyl locking rail includes biasing wings which engage the inner side walls of the wood bumper panels and contribute to the integrity, rigidity, and stability of the entire assembly. Additionally, the locking rail is contoured to mate with corresponding contoured surfaces on the inner side walls of the bumper panels.
For a better appreciation of the new quick-assembly corner protector, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.
