Two connecting elements are arranged in the mediate portion of the base; each connecting element is pivoted to one of the support rods. The other two support rods which are not pivoted to the connecting elements are also connected with a respective one of the connecting elements. Two holders, two pivotal rods, two mediate rods and two mediate supports used to support the base are provided wherein the pivotal rods are pivoted to both the connecting elements and the mediate supports at two ends and the mediate rods are pivoted to the holders at one end and connected to the mediate support at the other end, and the support rods pivoted to the connecting elements are further connected to the holders such that the bed can be collapsed into a compact one after one pulls the base upward from the mediate portion thereof.

Abstract: A bedding cover is described for use on a bed. The cover has a flap positioned at its center, and extends laterally from one side to the other. The flap may be folded to cover one or the other ends of the cover, and is large enough to fully cover the selected end. The flap has the bedding pattern of one end of the cover on one side and of the other end of the cover on the other side so that when it is folded to cover the first side, the entire surface of the cover presents a uniform appearance, and when it is folded to cover the other side, the entire surface of the cover presents a uniform appearance also, but of a selected different design or color, etc. In a second embodiment, the reverse side of the cover may be constructed to provide a third and a fourth appearance when the cover is turned over.

Abstract: The invention is directed to a latch releasing mechanism for a container having a hinged or removable lid. A latching arm is disposed adjacent the container lid to prevent an opening of the lid, and a cable connects the latching arm to the locking mechanism. The elements of the latching mechanism comprise a slide plate to which the cable is fixed; a spring for urging the slide plate to a latched position, a guide member for guiding the slide plate, and a trigger ball which blocks movement of the slide am in the latched position. When the container is tilted forward by a predetermined angle, the trigger ball becomes dislodged from the latching position to enable movement of the slide plate, and subsequent movement of the latching arm. When the latching arm is moved out of the path of travel for the container lid, the contents of the container may be removed.

Abstract: An improved double-locking mechanism for handcuffs is disclosed. In the preferred embodiments, a standard pawl and multi-piece slide-bolt assembly have been modified to prevent premature sliding of the bolt into its "double-locking" position, and to prevent dislodging of the bolt back into its "non-locking" position. The unique slide bolt, or the nearby lock casing, is angularly offset to create a fulcrum. The bolt also has an underlying tab that is designed to rest in either of two side-by-side locator notches atop a cuff's pawl. One notch firmly locates the bolt in a double-locking position, while the other notch normally keeps it in a non-locking position. To shift the bolt into its double-locking position, an authorized user presses any suitable actuator (e.g., the tiny end of a handcuff key or a ball-point pen end) against an exposed inclined end of the bolt. This pivots the bolt about the fulcrum and against the casing, so that it lifts the tab out of the non-locking locator notch.

Abstract: A modular door handle assembly has a door handle on a rotatable handle shaft mounted on a housing having a face with a bore for receiving the handle shaft. Dual-function studs retain a cover on the housing and have provision for mounting the door handle assembly to a door. Other provisions, within the housing, provide for operating a door latch in response to rotation of the door handle together with a mechanism for returning the handle to a parked position upon release of the handle from rotating force and a locking feature for releasably locking the door handle assembly to prevent operation of the door latch. The handle return and locking features are both driven by a pair of dual acting springs. The modular design simplifies repair and replacement of the assembly.
