1,037,570. Furniture joints. S. WINIKOFF. Dec. 30, 1964 [April 22, 1964], No. 52861/64. Heading A4H. [Also in Divisions E1 and F2] Couplings for tubes comprise plug elements 44 with axial screw threaded apertures 68 which is inserted into the ends of the tubes and retained there by frictional contact, connector members 46 having a body portion 70 with an aperture 76 and an end portion 72 consisting either of a stud 78 or of a cavity into which a stud 78 may be screwed, and another stud 48 having a body diameter less than the diameter of the hole 76 for screwing into another plug element 44. The stud 48 is attached to the connector 46 by a nut 80. The plug 44 may be recessed at 66 to receive the square bottom of the connector end 72; contact with the walls of the tube may be made by raised lands 60 on the plug, or the plug may simply be milled around the contact surface. The plug may have a flange 56 or nut. In an alternative form of connector (Fig. 2, not shown) a stud 78, or a screwed recess to receive one is provided at either end of the connector body 70. Various structures such as a frame for a shed or the like and a clothing rack are illustrated (Figs. 12 and 22 respectively, not shown) with details of joints used. |
