Abstract: A lift apparatus includes a folding frame assembly and a pair of support members which are connected to the folding frame assembly by a linkage. The apparatus is mounted on a coffee table base and is capable of an open position in which the table top of the coffee table is lifted to a height appropriate for a dining table. The support member supports a hinged leaf which increases the size of the table top when in the open position.

Abstract: A retaining element for swinging weights includes two supporting parts which are spaced apart along a covering. The covering is pivotable around a shaft of rotation between two angular positions. A short arm, which is fixed against pivoting on the shaft of rotation, extends obliquely to the direction of extension of the covering and the direction between the supporting parts. One of the supporting parts is pivotally connected through a rod, to the free end of the oblique arm. Stretchable elements extend between the spaced supporting aparts. Pivoting of the covering between its angular positions pulls the supporting parts apart or permits them to move together, varying the tension on the stretchable elements. The second supporting part is supported on a threaded rod which permits adjustment of the tension of the stretchable elements.

Abstract: For adjusting the tilt height of one end of a bed, a bed frame, a tiltable frame section attached to the frame, a longitudinally oriented bar secured to the section, a bar receiving means having an opening through which the bar passes supported on the frame, the receiving means opening being orientable from a position at which it misaligns with the bar and blocks sliding of the bar therethrough to a position at which it aligns with the bar and permits the bar to slide through, thereby permitting the frame section to gradually recover from tilted orientation.
