Patent ID: 8096728

Claim:
A connectable panel comprising: a frame having first and second parallel and spaced apart edges, said first edge including at least one connector apparatus comprising: first and second spaced apart generally coplanar walls; and a support between said first and second walls; said first wall comprising: a first guiding surface; and a first stopping surface extending at a first angle to said first guiding surface; said second wall comprising: a second guiding surface opposite at least a portion of said first guiding surface and generally facing towards said first guiding surface; a second stopping surface extending from said second guiding surface away from said first guiding surface; and a third stopping surface extending at a second angle to said second stopping surface, at least a portion of said third stopping surface opposite said first stopping surface; said support having a fourth stopping surface generally opposite said second stopping surface and disposed at third and fourth angles to said first and third stopping surfaces respectively; and at least one projection projecting away from said second edge, said projection having first and second opposite ends, said first end coupled to said second edge and said second end having a retainer thereon; wherein said first and second guiding surfaces of said at least one connector apparatus are positioned to permit passage therebetween of said projection of a first adjacent connectable panel; wherein said first, second, third, and fourth stopping surfaces of said connector apparatus are positioned to hold said projection of the first adjacent connectable panel releasably therebetween and to prevent said retainer of the first adjacent connectable panel from passing therebetween; and wherein said frame and said connector apparatus define a cavity for receiving said retainer of the first adjacent connectable panel when said projection of the first adjacent connectable panel is moved between said first and second guiding surfaces and when said projection of the first adjacent connectable panel is positioned between said first, second, third, and fourth stopping surfaces of said connector apparatus.
