A pivot mechanism for guiding in rotation comprises a mobile element connected to a fixed element through flexible connections; with the flexible elements being configured to guide the mobile element according to a rotational movement in a plane, around a pivoting axis perpendicular to the plane; with each of the flexible connections comprising an intermediary junction provided with an expansion slot, the expansion slot being configured to expand during the rotation of the mobile element, so that the mobile element can pivot according to a second angular amplitude that is greater than a first angular amplitude achieved without said expansion slot; with the intermediary junctions being connected to one another by a coupling member; each of the coupling members being configured so as to prevent a movement out of the plane and a lateral movement in the plane of the mobile element. The pivot mechanism has a very high rotational amplitude.

Devices to couple a drive hub to a driven hub. The devices may comprise a drive hub contoured end connected to a first end of a spacer column and to a spacer drive hub flange. A portion of the drive hub contoured end may project radially out from the spacer column with a first contoured side and a first flat side and may allow movement in an axial direction and transmit torque and an axial load. The devices may comprise a driven hub contoured end connected to a second end of the spacer column and to a spacer driven hub flange. A portion of the driven hub contoured end may project radially out from the spacer column with a second contoured side and a second flat side and may allow movement in an axial direction and transmit torque and an axial load.

In a railing system comprising a railing panel frontage which extends continuously along the course of the railing and consists of a plurality of mutually adjacent railing panels, in order to increase an additional resistance and security against destruction, an additional securing element, which, given a properly erected railing, extends between a handrail profile, resting on the railing panels, and a structural body or a holding profile disposed on the structural body and connects the handrail profile to the structural body or the holding profile, is provided.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically.

Resin pallets having a deck and a base, where the deck and base are joined by an interlock, which is optionally reversible, are described. Methods of making such pallets by assembling the pallets by interlocking parts to form the pallets, in an optionally reversible method, are also described.

A bed comprises a fixed width deck section, a wing movably coupled to the fixed width section, and a rack and pinion mechanism for extending and retracting the wing.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.
