Abstract
Abstract When attaching cabinet parts together such as the sides of the cabinet to the top or bottom panels or partitions between top and bottom panels or between side panels, it is difficult to produce a firm joint particularly if particle board or plywood is used in the construction, without the use of screws, nails, glue and the like. This prevents easy assembly or disassembly and makes shipping and storage space consuming and expensive. By providing an undercut slot or recess in one part and a substantially parallel sided groove in the edge of the other part, a plastic extrusion can be used to secure the two panels together substantially at right angles to one another. The extrusion is provided with an anchoring key portion which is hammered or forced into frictional engagement within the parallel sided groove. An outwardly flanging attaching portion is formed on the underside of the anchoring portion which slidably engages axially within the undercut slot of the other panel so that lateral movement of the two panels is prevented in either direction and these two panels are held firmly together.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
232 words
In a construction which includes a first planar panel part and a second planar part detachably secured to one side of said first panel part by one edge thereof and held at an angle thereto, said first panel part having an elongated undercut slot formed in said one side thereof, said second panel part having a substantially parallel sided, elongated groove formed in said one edge thereof; an integral, one piece means detachably, rigidly securing said second panel part to said first panel part, said means comprising an elongated anchor portion elongated in cross section for substantially non-detachable, force fit frictional engagement within the substantially parallel sided groove of said second panel part and having an upper edge substantially flush with said one edge of said panel part when installed thereon, and an elongated resilient attaching portion extending longitudinally from and integral with said anchor portion on said upper edge of said anchor portion and including a base portion extending substantially transverse to and beyond each side of said anchor portion, the external cross sectional shape and dimensions of said attaching portion being similar to and slightly wider than the cross sectional shape and dimensions of said undercut slot such that said attaching portion slidably and removably engages said undercut slot axially and resiliently secures said panel parts rigidly together in a direction other than axially with respect to said undercut slot.
Claim 2
Dependent Claim
232 words
In a construction which includes a first planar panel part and a second planar part detachably secured to one side of said first panel part by one edge thereof and held at an angle thereto, said first panel part having an elongated undercut slot formed in said one side thereof, said second panel part having a substantially parallel sided, elongated groove formed in said one edge thereof; an integral, one piece means detachably, rigidly securing said second panel part to said first panel part, said means comprising an elongated anchor portion elongated in cross section for substantially non-detachable, force fit frictional engagement within the substantially parallel sided groove of said second panel part and having an upper edge substantially flush with said one edge of said panel part when installed thereon, and an elongated resilient attaching portion extending longitudinally from and integral with said anchor portion on said upper edge of said anchor portion and including a base portion extending substantially transverse to and beyond each side of said anchor portion, the external cross sectional shape and dimensions of said attaching portion being similar to and slightly wider than the cross sectional shape and dimensions of said undercut slot such that said attaching portion slidably and removably engages said undercut slot axially and resiliently secures said panel parts rigidly together in a direction other than axially with respect to said undercut slot.
