  • Patent number: 6702411
    Abstract: A waste receptacle or other household items are placed upon a movable shelf or drawer under the counter in a space covered by an openable door. The shelf or drawer is movable between a first, retracted, mounted position stowed within the cabinet and a second, deployed, position removed from the cabinet. The user can withdraw the shelf or drawer hands-free from the cabinet and place items within the waste receptacle or drawer by simply opening the cabinet door. To stow the tray or drawer, the user simply pushes the tray or drawer back within the cabinet, into the retracted position. A novel latch assembly retains the drawer or tray, and, hence the receptacle or other item(s), in the retracted position, and the door can be closed to conceal the same. Upon closing the door, a lever attached to the door causes the latch mechanism to unlatch, releasing the drawer, which then abuts against the cabinet door.

  • Patent number: 6350096
    Abstract: A binding assembly structured to secure a plurality of material sheets having a series of binding aperture on a corresponding series of binding elements of the type that include a wide perimeter flange. The binding assembly includes an alignment assembly which maintains the binding elements generally vertically oriented, a guide assembly which positions an edge of the material sheet in generally aligned relation with a perpendicular axis region of the binding elements, a displacement assembly which urges the material sheet and the binding elements into coupled engagement with one another at the corresponding binding apertures on the material sheet, and an actuation assembly which initiates operation of the displacement assembly.

  • Patent number: 5600951
    Abstract: A hydraulic transmission system including a hydraulic piston drivingly connected to a cam through a plunger shaft, the plunger shaft being connected to the cam through a lever arm such that rotation of the cam results in reciprocating movement of the plunger shaft between a withdrawn and an inserted position, fluid being drawn into a hydraulic chamber of the hydraulic piston upon pulled movement of the plunger shaft to the withdrawn position, and fluid being pushed out of the hydraulic piston upon pushed movement of the plunger shaft to the inserted position. Fluid exiting the hydraulic piston is directed into a turbine chamber so as to drivingly rotate a first and a second rotor matingly disposed therein. The first rotor includes a first plurality of tooth elements about a periphery thereof which define a first plurality of trough elements, and the second rotor includes a second plurality of trough elements disposed about a periphery thereof which define a second plurality of tooth elements.

  • Patent number: 5056578
    Abstract: A carrier assembly and support frame of the type used to movably support one of a plurality of vertically oriented slats in a vertical blind assembly and incorporating a plurality of gears which interact with one another and with a splined tilt rod to cause rotation of the supported slat upon rotation of the tilt rod. Two of the gear structures comprise elongated rack gears movable both with one another upon rotation of the tilt rod and relative to one another to define a clutch mechanism if the slat is obstructed from rotation about its own longitudinal access.

  • Patent number: 4848435
    Abstract: This invention relates to a vertical blind assembly of the type typically having a plurality of vertically oriented slats each supported from a carrier assembly in a manner which selectively provides for the angular orientation of each of the slats in synchronized relation to one another about their longitudinal axis and also for the travel of the slats and the associated and supported carrier assembly along the length of a header structure further within each of the carrier assemblies is structured to include a clutch mechanism which automatically provides for a realignment of any inadvertently displaced or jammed slates and associated support stems or components associated therewith and a simplified control means and end, rod support for attachment of a tilt rod for manipulating both the aforementioned angular orientation of the slats relative to one another and their travel along the length of the header structure.
