Abstract: A rise assist apparatus comprising a handrail in the form of a convoluted section attached to a vertical pole, and stabilized by a bed frame attachment member and a floor contacting base frame. Alternatively, the rise assist apparatus may be wall mounted, being stabilized by a system of mounted wall brackets. The rise assist apparatus further includes an upper curved, horizontal leveraging handle, which extends from the pole-like support structure. Specifically, the rise assist apparatus allows the user to build momentum by pushing off the upper hand grip, and allows the user to control the momentum by regaining balance, and readjusting posture, by gripping the lower handrail member. Additionally, the user can use the curved grip with one hand, while simultaneously reaching for the handrail during the rising movement thereby allowing the user to support himself or herself as they rise out of bed.

Abstract: Invention provides a self latching, object-holding fixture designed to release a held object whenever the object is turned slightly in either direction. Fixture has a shaped housing and the object to be held has a mated opening of a similar matching shape. Placing an object to be held locks the object to the fixture by spring-loaded latching action. The fixture housing covers a fixed spring holding base that is anchored by any suitable means to a support surface. Covering that fixed-position base, except for exposed spring-loaded keeper latches, is a rotatable casing having a pair of spring compression cam surfaces carried by the casing. Using a cam follower action, these cam surfaces selectively cause the spring to collapse in response to the rotation of the casing holding in either direction of casing rotation. As the object/casing is turned slightly, this cam follower/spring collapse action releasably disengages the keepers from the object being held.
