1,068,464. Furniture joints. A. G. NIJHUIS. April 7, 1965 [Sept. 29, 1964 No. 14807/65. Heading A4H. [Also in Division E1] A corner joint comprises two frame members 1, 2 interconnected by a corner joint piece having two angularly disposed legs 7 which are each a jam fit in a substantially rectangular aperture 3 in a corresponding end of a frame member, each aperture 3 having one opposite pair of surfaces 4, 5 with the same cylindrical curvature which are jammingly engaged by a corresponding pair of surfaces 8, 9 on each leg 7 and the other pairs of opposite surfaces 10, 11 and 12, 13 being formed with sufficient clearance to permit on assembly a limited rotation of the legs 7 with a relative sliding of the cylindrical surfaces 4, 5 and 8, 9. The legs 7 or apertures 3 may be formed with central longitudinal ribs (14) (Fig. 4, not shown) providing an engagement between the non cylindrical surfaces 10, 11 and 12, 13. Alternatively, each leg may be split longitudinally to receive a compressible wedge member (16 or 18) (Figs. 5, 6, not shown) which may also provide the ribs. When wedges are used, suitable bores (19) (Fig. 2, not shown) are provided in the frames 1, 2 to receive pins. The wedge may be conical and threaded (Fig. 12, not shown). The legs 7 may be glued in the apertures 3. One cylindrical surface of the leg may be provided by a separate wedge (Fig. 10, not shown). The legs 7 may be hinged together to provide an adjustable corner angle. In another embodiment (Fig. 13, not shown) one non cylindrical wall of the aperture may be formed by a detachable plate (28) which has hooked edges for a sliding engagement with guides in a corresponding frame member. The frames 1, 2 are formed with flanges 6 or other means to receive a pane of glass, panel or wooden lath. |
