Abstract: A roller assembly for use in a telescoping slide assembly having at least two slide members that are slidably interconnected for movement along the longitudinal axis of the slide assembly, the roller assembly comprising a plurality of rollers for maintaining vertical spacing between the interconnected slide members, a spacer maintaining lateral spacing between the interconnected slide members, formed to include a first vertical side wall having a first opening, a second vertical side wall having a second opening, and a laterally extending open-ended aperture interconnection the first and second openings, the second means further including a bearing loosely received in the laterally extending open-ended aperture for lateral sliding movement relative to the spacer and arranged to extend through each of the first and second openings, and side walls for longitudinally aligning the plurality of rollers, positioned to lie adjacent to the rollers for longitudinally aligning the rollers so that the rollers roll along

Abstract: A hand controller for use with a home electronic video game produces electrical control signals in response to manipulation of a control stick extending through an aperture in the controller housing. The control stick is attached to an actuator stem which forms part of a multi-position switch assembly within the housing. The switch assembly includes a helical coil spring which is attached at one end to an interior surface of the housing and is arranged to concentrically receive the actuator stem so as to support the actuator stem and control stick in an upright non-actuated position. Displacement of the control stick and actuator stem causes the helical spring to contact one or more of a plurality of electrical contact pads disposed generally concentrically around the spring. This causes appropriate control signal to be produced for application to the video game.

Abstract: An integral plastic fastener for a plastic article in the form of a cylindrical lug extending from the article and a hollow core in the central portion of the lug, the length of the core being greater than the length of the lug, extending into the plastic article. The diameter of the lug preferably is the same along its length.

Abstract: A seat belt buckle assembly having a plastic cover and a plastic push button actuator. The underside of the cover is provided with three channels adjacent its forward end and a ledge which extends over part of the channels. The push button has three forwardly extending legs which are received in the channels of the cover to provide a pivot point for the button and limit lateral shifting.
