Abstract: Construction assembly for spatial structure intended to be releasably fastened to an element, the construction assembly includes a support and a screw. The support has a threaded hole, a front surface and an abutting surface. The screw is movable with respect to the support in coupled translation and rotation between a retracted position and a protruding position. In a fixing position, the screw protrudes from the front surface of the support, the screw abuts against the abutting surface of the support, and the screw is able to rotate with respect to the support around the longitudinal axis without translating along the longitudinal axis.

Abstract: Construction assembly (1) for spatial structure comprising a support (10), a screw (50) and a drive shaft (60). The support (10) has a peripheral surface (30, 72) extends along a longitudinal direction (X). The support (10) comprises a first hole (12) extending through said peripheral surface (30) and a second hole (22) receiving the screw (50). The drive shaft (60) is pivotally mounted with respect to the support (10) along the cross axis (Y). The cross axis (Y) is not parallel to the longitudinal direction (X) and extends through the first hole (12) of the support (10), and rotation of the drive shaft (60) around the cross axis (Y) is mechanically linked to rotation of the screw (50) around the longitudinal axis (X).

Abstract: A display unit back wall includes in a structure reinforced by stiffener bars two parallel uprights forming at least part of a slideway for a plurality of stacked slats, the two uprights forming the two lateral sides of a U-shape unitary construction frame. A crossmember is fixed to the bottom ends of the two uprights. The stiffener bars fixed to the uprights and to the crossmember are all within the peripheral edge of the frame. The U-shape unitary construction frame is made from channel-section, and each side of the slideway is formed between one of the two flanges of the upright and a facing side of the associated stiffener bar.

Abstract: A channel is adapted to receive partly nested objects in a queue which a clamp/pusher member associated with a return spring urges towards an anterior abutment wall, the pusher member is associated with a slide member sliding in a central guide corridor, while the return spring forms at least one outward run in each of the two side passages between at least one direction-changer pulley wheel and an anchor point. A plurality of merchandisers may be mounted on a strip member for the purposes of aligning the merchandisers with the shelving and securing them to it.
