  • Patent number: 8083269
    Abstract: The apparatus comprises a gripping-operating unit including a gripping subassembly, a base subassembly for mounting the components of the unit and an operating subassembly. The gripping subassembly includes a gripper, from which, at one of its vertical extremity, a lever, integral with the gripper, extends horizontally. The base subassembly generally includes an elongated body and a positioning-attachment element connected to the latter. The operating subassembly comprises a spring guide block with opposed channels, a helical compression spring, located in one of the channels, and a pushing pin having a tooth like extension. Should the lever act on the pushing pin, the later, via the tooth like extension, operates against the helical compression spring, and simultaneously moves beyond the spring guide bloc. When a lock is used, a subassembly strike-stopper and a lock actuator-stopper deactivator subassembly are included.

  • Patent number: 7757869
    Abstract: A flexible deformable retainer has top and bottom horizontal walls and lateral vertical walls, the latter being perpendicular to a slatwall track, respectively to top and bottom horizontal walls of the latter. Top and bottom horizontal walls have edges abutting a central flat body of a hanger's bracket and each outward edge has a removal cutoff. Lateral vertical walls are used for insertion into vertical slits provided in a hanger's bracket. Each lateral vertical wall includes a curvature configured for snapping into a vertical slit. The retainer is able when the hanger is bumped vertically, to engage, via upper edges of its lateral vertical walls, a horizontal top of an intermediate channel of the slatwall track. A gap is provided between a horizontal top of the latter and the upper edges of retainer's lateral vertical walls.

  • Patent number: 7717279
    Abstract: A slatwall track, which comprises a horizontally elongated assembly of uniform thickness and has a front and a back side, incorporates an upwardly extending member, retracted from the front side, for intermeshing with a downwardly extending member, coplanar with the front side, of another above located slatwall track. The slatwall track further incorporates one or more channel subassemblies for supporting items. The channel subassemblies are generally followed downwardly by rigidity boxes. A member for stopping projecting backwardly from the downwardly extending member limits an upward movement of a lower slatwall rack during intermeshing. The spacing between an outside extremity of the member for stopping and a wall to which the slatwall track is secured and the spacing between the upwardly extending member and the same wall are equal and correspond to a thickness of a panel intended to be inserted, between two slatwall tracks, into these spacings.
