Abstract: A push-bar includes a cross-bar which has two ends and a longitudinal cross-bar axis from end to end, and a mounting member mounted on each end of the cross-bar and extending along a mounting member axis. Each mounting member defines an aperture for receiving therein and encircling a wheelchair handle and includes a clamp mechanism for engaging a wheelchair handle disposed in the aperture.

Abstract: A multi-part screw cap construction for a container, comprising a thin-walled cup-like shell, an insert member having an annular side wall receivable in the shell, and a one-piece weight member constituted essentially as a single wire coil disposed completely within the shell at a location between its closed end and the end of the insert member, so as to provide a "weighted feel" to the cap. The coil is secured against looseness or vibration by suitable adhesive or cement, and the insert member can be pressed into the shell and adhered thereto by the adhesive while the latter is still tacky. The insert member is cup-like, and internally threaded for cooperation with the external threads on the neck of the container.
