Cabinet construction

Claim 2

A cabinet construction comprising a frame having generally rectangular end gables connected at each corner by longitudinally extending rails, said end gables each having opposite side faces and corner notches, said opposite side faces having kerfs arranged in pairs with one pair spaced from each notch to define a tongue, said rails each having an inner face and end edges containing transversely extending rabbets, a rib projecting into each rabbet adjacent the inner face, said tongues being received in the rabbets with the ribs lodged in some of the kerfs, said inner faces each having a plurality of transverse grooves regularly spaced apart along the length of the rail between the rabbeted end edges thereof, and locking means including a member inserted into a transverse slot for securing each rail end to an end gable.

Claim 3

Cabinet construction as claimed in claim 1, and including an intermediate gable in the frame, said intermediate gable being identical to the end gable and having tongues entered into transverse grooves of the rails.

Claim 4

Cabinet construction as claimed in claim 1, in which said inner face of each rail has a longitudinal groove extending through the transverse grooves therein, said transverse grooves each having opposing ribs adjacent the inner face, said members each being a bar nut retained in its transverse groove by the opposing ribs thereof, a bolt engaging each bar nut and extending parallel to the longitudinal groove, said end gables each having a hole adjacent each corner notch and through which a bolt extends to project outwardly of said gable.

Claim 5

Cabinet construction as claimed in claim 3, in which each of said bar nut has an end edge and is provided with a longitudinal slot extending into said end edge to approximately the centre of said bar nut, said longitudinal slot having opposing faces provided with thread-like striations engaging the threads of a bolt.

Claim 6

Cabinet construction as claimed in claim 1, in which each of said gables has front and rear edges and a vertical row of holes adjacent each of said edges, a load-carrying inner assembly mounted within the frame, and hanger means fitted to a selected hole of a vertical row of holes for securing a part of the inner assembly to a gable.

Claim 7

Cabinet construction as claimed in claim 5, in which said inner assembly includes a vertical support connecting rails at the rear of the frame, said vertical support having a T-shaped spline housed within transverse grooves of the connected rails.

Claim 8

Cabinet construction comprising a frame having generally rectangular end gables connected at each corner by longitudinally extending rails, said end gables each having opposite side faces and corner notches, said opposite side faces having kerfs arranged in pairs with one pair spaced from each notch to define a tongue, said rails each having an inner face and end edges containing transversely extending rabbets, a rib projecting into each rabbet adjacent the inner face, said tongues being received in the rabbets with the ribs lodged in some of the kerfs, said inner faces each having a plurality of transverse grooves regularly spaced apart along the length of the rail between the rabbetted end edges thereof, said inner face of each rail having a longitudinal groove extending through the transverse grooves therein, said transverse grooves each having opposing ribs adjacent the inner face, a bar nut and bolt connecting each rail end to an end gable, each of said bar nuts being housed within a transverse groove for engagement by a bolt extending inwardly through a gable alongside the longitudinal groove in the rail.

Claim 9

Cabinet construction comprising a frame having generally rectangular end gables connected at each corner by longitudinally extending rails, said end gables each having opposite side faces and corner notches, said opposite side faces having kerfs arranged in pairs with one pair spaced from each notch to define a tongue, said rails each having an inner face and end edges containing transversely extending rabbets, a rib projecting into each rabbet adjacent the inner face, said tongues being received in the rabbets with the ribs lodged in some of the kerfs, said inner faces each having a plurality of transverse grooves regularly spaced apart along the length of the rail between the rabbetted end edges thereof, said inner face of each rail having a longitudinal groove extending through the transverse grooves therein, said transverse grooves each having opposing ribs adjacent the inner face, a bar nut and bolt connecting each rail end to an end gable, each of said bar nuts being housed within a transverse groove for engagement by a bolt extending inwardly through a gable alongside the longitudinal groove in the rail.

Claim 10

Cabinet construction as claimed in claim 7, and including a door hung on an end gable by hinge mEans, said hinge means comprising a plate secured to an inner face of the end gable to project beyond an end edge thereof, a stem hingedly secured at one end to the projecting end of the plate and having a transverse threaded hole, said door having an end edge provided with an opening to receive the stem, and a threaded fastener extending into the door to enter the transverse threaded hole.
