    Abstract: A wheel assembly adapted to travel along guide rails or tracks. The assembly includes a roller formed of porous sintered metal, a shaft attached to a supporting body and an adapter to which both the roller and shaft are connected. The adapter includes a cylindrical inner portion with an axial socket to receive the shaft and a cylindrical inner portion of a smaller diameter to define an annular inner shoulder. A spring retainer secures the roller to the adapter.

    Abstract: A sectional door is disclosed that includes a safety system. The safety system includes a shield apparatus, an improved support track, reverse angle track shields, and hemmed roller track edges to prevent injury or harm to body parts errantly placed within or around the support track during the opening or closing of the sectional door. The sectional door includes a plurality of door sections hingedly joined in an edge-to-edge relationship to form the completed sectional door. The sectional door further include support rollers attached to the door sections, and a pair of support tracks, in which the support rollers are confined. Each support roller further includes a circular or rectangular roller shield that is mounted to the axle of the support roller outside of the support track where it is proximate the support track in such a manner as to limit or prevent any fingers from engaging within the support track with the support rollers. The dimensions of the protective shield is larger than the support rollers so as to provide adequate shielding for the support roller. Protective shield wings are provided to enclose the support track and prevent objects from interfering with the roller as well as to provide transport guidance within the support track where track sections meet. Further, the outer edge of the protective shield is blunted or protected in a manner to prevent harm during operation. The reverse angle track shields are constructed of a solid metal piece so as to prevent objects from passing between the support track and a mounting surface. Additionally, the adjacent edge of the support track is also formed into a folded single hem, either outwardly or inwardly, to prevent fingers from being cut as the fingers are brushed aside by the roller shield.

    Abstract: An apparatus for supporting one or more theatrical panels and, in a more specific aspect, a carriage assembly adapted for such task in association with a horizontal track having an upper guide surface and a lower guide surface, provide horizontal movement quietly, smoothly, with low frictional resistance and in a highly-linear fashion with low rock and sway. A horizontal track comprising an upper guide surface and a lower guide surface supports a carriage assembly having a plurality of upper guide wheels and a plurality of lower guide wheels. The upper guide wheels are supported in rolling contact with the upper guide surface and the lower guide wheels are supported in rolling contact with the lower guide surface. The axles supporting the upper guide wheels are preferably horizontally offset from vertical lines extending through any of the axles supporting the lower guide wheels. The guide wheels are preferably resilient at least at the surface and grooved to engage the guide surfaces.

    Abstract: A sliding door suspension system and a sliding door assembly for supporting a heavy sliding door from a door frame includes a rail horizontally mounted to the door frame. The suspension system includes a roller assembly which rollingly engages the rail and supports the heavy door. The roller assembly includes an axle or shaft having a bearing surface. The axle has at least one threaded end for securing the roller assembly and for attaching the roller assembly to a door hanger from which the heavy door is suspended. The roller assembly further includes a roller with a concentric hollow bore for seating a bearing assembly or bushing through which the axle extends in supportive engagement with the bearing assembly. The rail has a convex arcuate upper roller guide surface. The roller has a concave arcuate roller guide engaging surface which conforms to and engages the upper surface of the rail. The roller assembly also includes a door height and alignment adjusting member which threadably engages the axle. In one embodiment, the door height adjusting member comprises an eccentric sleeve, whereas in an alternative embodiment, the door height adjusting member comprises an adjuster block.
