  • Patent number: 7735541
    Abstract: A sheet material tensioning apparatus includes frame members interconnected one with another to define a closed contour. The apparatus applies tension to sheet material by imposing a separation between frame members to expand the closed contour. Beneficially, the sheet material tensioning apparatus includes an edge-bridging mechanism, such as a spline, to span the gap between the separated frame members. The edge-bridging mechanism maintains the continuity of the edge supporting the sheet material. The sheet material apparatus may include a crossbar assembly to add rigidity to long frame members, while maintaining planar alignment even under considerable compression.

  • Patent number: 7444771
    Abstract: A device for continuously or intermittently displaying graphic material, such as advertisements on the side or rear of a moving vehicle. The vehicle is provided with various sensors which determine the speed of the vehicle as well as whether the vehicle has been parked for a predetermined period of time. Based upon the output of the sensors, the movement of scrolled display containing graphics such as advertisements would be controlled.

  • Patent number: 5158310
    Abstract: A display system (299) includes a visual display unit (300) mounted on a shopping cart (12d). In one preferred embodiment, a low-intensity ultrasonic signal is emitted by a transmitter (308) positioned at a desired location within a store for reception by a transducer (306) mounted on the shopping cart. The signal from the transducer (306) is transmitted to a switching circuit (316) to activate visual indicators in the form of directional lights (320, 322) thereby to direct the shoppers attention to a particular item located adjacent the transmitter (308).

  • Patent number: 5114349
    Abstract: An element for a didactic play, of the type capable of showing several surfaces carrying different representations, which may possibly be combined with the representations of other elements forming a set, in order to compose writings, images or the like, comprising a support, a prismatic body pivoted on the support and carrying on its faces some representations, and a control member carried by the support and capable, when operated, of acting on the prismatic body by causing a rotation thereof along the angle by which each face of the element is replaced by the subsequent face. The control member is formed by a push-button whose operation causes a rotation of the prismatic body in a preestablished direction by acting, by means of a pawl being a part of an inner operating member, onto an arrangement with escapement wheel carried by an end of the prismatic body. The set of such elements moreover includes a tray suitable for containing a number of elements, ordered by lines and columns.

  • Patent number: 5072956
    Abstract: A powered display is mounted on a shopping cart (12'") and powered by movement of the shopping cart. In one preferred embodiment of the present invention, the powered display includes an electronic display (260). Rotational power from a wheel (22'") of the shopping cart is transmitted through a bowden cable (16'") to a generator (262). The generator converts the rotational power to electrical energy to power the electronic display.

  • Patent number: 4930795
    Abstract: A rotary display (10) for printed advertisements (40) is mounted on a shopping cart (12) and advanced by movement of the shopping cart. The rotary display includes an elongated rotary display drum (14) on which the advertisements are disposed. The display drum is drivingly linked by the meshing of a follower gear (62) with a drive gear (60) that is attached to one end (54) of a bowden cable (16). The opposite end of the bowden cable is drivingly linked to a wheel (22) of the shopping cart by a follower gear (64) that meshes with a drive gear (66) mounted on the wheel. Rotation of the shopping cart wheel is transmitted via the bowden cable to the display drum to cause rotational display of the advertisements contained thereon.
