A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

The bearing structure for shelving comprises: —a vertical upright comprising a first metal section provided with at least a first longitudinal side and with at least a second longitudinal side, the first longitudinal side and the second longitudinal side being flat, continuous and transverse to each other; —a longitudinal cross-piece; —an angular bracket to be interposed between the vertical upright and the longitudinal cross-piece and comprising a first longitudinal face and a second longitudinal face, the first longitudinal face and the second longitudinal face being flat, contiguous and transverse to each other; wherein it comprises first connecting means arranged on the first longitudinal side and the first longitudinal face, and second connecting means, arranged on the second longitudinal side and the second longitudinal face, the first connecting means and the second connecting means coupling the angular bracket to the vertical upright.

A frame unit includes first and second bars spaced apart from each other, third bars disposed between the first and second bars, and connectors removably connecting the third bars with the first and second bars. A connector includes a body fixedly connected with the first or second bar, a casing defining an interior to receive an end of a third bar, and a slot allowing insertion of the end of the third bar into the casing. The interior defined by the casing has narrow and wide sides corresponding to the narrow and wide sides of the end of the third bar. As such, when the end of the third bar is inserted into the casing, the end of the third bar is prevented from any translational movement within the casing. The connectors allow quick and easy connection of bars, and in the meantime enhance the stability of the frame unit.

A shelf support, especially for loft shelving, comprises an elongate member intended to support a shelf, the member having a respective socket at each of two mutually opposite ends, and two mounting brackets each comprising two spaced-apart arms and each insertable into a respective one of the sockets to be positionable therein with the arms projecting away from the member in the length direction of the member so as to provide securing projections for embracing and securing to a respective mount on which the support is to be mounted.

A connector and a frame structure using the same, wherein the connector at least comprises a socket, a bolt and an expansion bolt; the socket comprises a connection end, and a slot, which extends along a length direction of the socket from an end surface of the connection end, is provided on the socket; the bolt comprises a bolt main body that is adapted to the slot, a front end of the bolt main body is provided with at least two expansion arms, and the bolt main body is internally provided with an expansion channel which traverses the bolt main body along a length direction; and the expansion bolt comprises an expansion bolt main body that matches the expansion channel, a front end of the expansion bolt main body is provided with an acting end that interacts with the expansion arm, and the socket and the bolt are tightly connected by means of an expansion force that is generated by the acting end opening the expansion arms. The aforementioned connector achieves quick disassembly and assembly, and also has the advantages of reliable connection, convenient disassembly and assembly and long service life.

A display stand connector can include a first part including a body member for attachment to a first part of a display stand and a protuberance extending from at least one surface of the body member. A second part of the display stand connector can include a base for attachment to a second part of the display stand, the base including a slot. The body member of the first part is locatable within the slot so as to connect the first and second parts of the display stand. The display stand connector is made from a pulp material.

A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.
