Structures for edge treatment and for decoration of counters and panels, and for the assembly thereof

Abstract

There is disclosed a family of structurally related extrusions which find broad utility as edge and comer trim and connectors for counter tops, cabinet faces and other sheet-like panels. The extrusions serve as joinders or couplers to cover and to protect exposed edges of the panels, to increase the load capacity of the panels, and to enhance the visual appearance thereof. In a preferred embodiment of the invention the extrusion defines spaced parallel arms forming a U-shaped channel into which an elongate edge of the panel is slidably received. Integrally-formed extensions of the arms define flanges forming coextensive opposed upper and lower slots for securing a decorative plate-like band to seat therewithin along a lineal expanse of the elongate extrusion. A wall bridging between upper and lower arms of the extrusion is formed with post means for insertion of a screw-like fastener therethrough for securing the extrusion in place against the presented end face of the sandwiched panel. In another embodiment of the invention the extrusion constitutes an integrally formed structural combination of two pairs of the basic components of the invention to define a unitary assembly for capping and securing a corner-defining juncture of a pair of structural panels. The provision of shims, readily insertable into the panel-receiving channel of the extrusion, imparts important versatility to the extrusion, facilitating accommodation of countertops, sheets or panels of various thickness dimensions.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001] The present invention relates to edge and joint treatment for panels or sheets. More particularly, the invention is directed to a series of versatile, multi-functional extrusions, etc., of metal or of plastics materials, or other compositions for attachment to lineally extending end sections or faces of panels or sheets including counter tops, table tops, shelving and cabinet walls.[0002] The extrusions pertain, generally, to cabinetry, and more specifically to an edge treatment for plywood, particle board, glass and related structures. The extrusions of the present invention are readily securable to structures to provide multiple benefits and enhancements, both physically and aesthetically, and beyond benefits accorded through other edging treatments.[0003] Prior art edgings of plastics materials are, in general, securable only through relatively weak frictional forces. Edgings of wood fail to cover surface chipping or any rough edges of ...

AI Technical Summary

Benefits of technology

[0009] An important feature of the invention, importing broad versatility and enhanced general utility to the extrusions, is the provision of shims of varied and selectable thickness and configuration. When necessary, the shims are effectively used to take up any excess "height" or space remaining in the channel of the extrusion before or after the sheet or panel has been inserted in place.

[0011] In another embodiment of the invention the extrusion is integrally formed with a depending, generally L-shaped leg for imparting increased strength to the extrusion, and which also permits the ganging of strips through utilization of a clasp to attach two separate strips in a parallel mode.

Problems solved by technology

Edgings of wood fail to cover surface chipping or any rough edges of the sheet goods to which they may be attached.

Moreover, the attachment process is exceedingly time demanding, requiring additional treatments such as gluing, nailing, putty and sanding.

Many of the presently employed aluminum or steel edgings are objectionally frail or flimsy, with exposed securing screws.
