  • Patent number: 4318195
    Abstract: A convertible furniture unit having upper and lower platforms which are mounted for conjoint movement. In different embodiments the upper platform comprises a bed or table and the lower platform can be structures such as a desk, a credenza and desk, and the like. Releasable locks are provided for holding the upper platform in a prone position while the lower platform is lowered. When the locks are released a torsion bar arrangement automatically applies a yieldable force urging the upper platform toward the upright position as the lower platform is raised while maintaining a horizontal attitude. Terminal movement of the upper platform is cushioned by an air pocket created in the recess of an upright housing. The upper and lower platforms are held in a upright mode by over center positioning of the pivot points which permits the upper platform to be manually pulled downwardly to convert the unit to another mode.

  • Patent number: 4315352
    Abstract: A locking device for bracelets and necklaces having two ends, each provided with a chain link, includes a first plate and a second plate which are pivotably coupled together for movement about a common pivot axis between an opening and locking position. The plates each have an aperture formed therethrough aligned with the pivot axis through which one of the chain links may extend and the first plate has a hook-like end portion for receiving the other of the chain links. The second plate has an arcuate slot formed therein running in a concentric manner with respect to the pivot axis which defines an arched portion on an end portion of the second plate disposed distal to the pivot axis relative to another end portion thereof. The arched portion also runs concentrically with respect to the pivot axis and, in the locking position, is received through the other chain link received in the hook-like end portion of the first plate.

  • Patent number: 4313243
    Abstract: A bight of a cable is wrapped around a sliding wedge thimble which, when one or both of the cable parts is pulled, jams the cable parts between convergent sides of the wedge thimble and opposed convergent sides of a casing. A key, when engaged through registering keyways of the wedge thimble and casing, limits the sliding movement of the wedge thimble so that the latter does not jam the cable parts but, rather, permits the cable to slip lengthwise around it. The key is tapered, and the keyways are so arranged that they serve to unjam the cable when the key is forced through the keyways.
