Abstract: A connecting device for structured elements with an improved force fit connection, of the type comprising a bolt with a floating nut and a sleeve portion near the head. The sleeve portion is adapted to be force fitted into a first structural member, is outwardly deformable and has a plurality of circumferential ribs. The bolt widens towards the sleeve end, so that when the threaded end is rotated by means of the floating nut into a second structural member, the sleeve is expanded inside the first member and enhances the force fit connection.

Abstract: A lock of the type generally described in Australian Patent Specification No. 552,608, comprising a bearing housing, a holding member and an eccentric pin, generally disposed and mechanically inter-related in the manner described in said specification, the holding member having a slot through which extends the journal of the eccentric pin; characterized in that the slot is so configured as to ensure that inadvertent rotation of the pin beyond the normal locking position is avoided.

Abstract: A lock of the type generally described in Australian Patent Specification No. 552,608, comprising a bearing housing, a holding member and an eccentric pin, generally disposed and mechanically inter-related in the manner described in said specification, the bearing housing having forwardly directed means adapted to extend through a slot of a profile bar or the like to which, in use, the lock is to be secured, and the holding member having a hook element at the forward end thereof; characterized in that the forwardly directed means is so configured as to provide a positive lock behind or around the slot on the opposite side of the slot to that which the hook element assumes when the lock is secured to the profile bar or the like.

Abstract: A shelving system comprising a shelf bracket of light weight material adapted to be fixed to an elongated substantially vertical slotted member. The bracket includes an insert of high tensile strength a portion of which is firmly embedded in the bracket at or near the top load carrying edge thereof. The insert has a free end extending from the bracket. Abutment means are provided adjacent the bottom edge of the bracket. The free end of the insert is shaped to engage the slot in the slotted member, while the abutment means abuts against the slotted member. A load placed on the bracket causes it to be firmly fixed in position relative to the slotted member through cantilever action.
