Abstract: This support or coupling device for suspending objects such as shelves or the like from rods comprises a front member formed with a rod-receiving groove and a back member for pressing and locking the rod in this groove. The two members are assembled by means of a screw-threaded cylindrical projection formed on one of them and of a tapped hole engageable by this projection. A central inner element projects from the inner face of the back member and the arrangement is such that this back member bears at three spaced and aligned points on the rod. A single handtool consisting of a key provided with a pair of studs is used for tightening and loosening the assembly by engaging these studs into corresponding holes formed in the back member. A disk-like member formed with an integral screw-threaded plug is used for fastening the object to the device by engaging this plug into a matching tapped hole formed in the front member.

Abstract: A shelf supporting apparatus comprising vertical cables extending between upper and lower anchoring members, attachment members being connected to the cables for receiving and supporting shelves and each cable being associated with a tensioning spring. Each lower anchoring member comprises two sockets housing a piston and the tensioning spring, the piston having an axial bore through which the cable extends. The upper anchoring member comprises a pair of screw engaging sockets housing a stop member to which the upper end of the cable is secured. Each attachment member is of unitary construction and has a slot for engaging the cable with screw holes at each end of the slot into which cable gripping screws can be engaged. The bulk of the anchoring members is reduced to a minimum.
