  • Patent number: 5467491
    Abstract: An improved bedding anchor, which comprises a somewhat U-shaped hook with a plastic retainer strip. An end of the bed sheet or like sheet material is wrapped around the retaining strip and the retaining strip with the end of the bed sheet wrapped therearound is inserted in the U-shaped hook. An elastic strip is connected to the hook at one end and at its other end. At the other end of the strip is a retaining pad which is preferably formed of a foam-like member, and is inserted between a box springs and a mattress. Preferably, a separate bedding anchor is located at each of the corners of a bed to retain the sheet in a taut condition.

  • Patent number: 5345631
    Abstract: An apparatus for raising one end of a bed which comprises the placement of elevator blocks under the support legs of one end of a conventional bed. The elevator block comprises top and bottom ends that are non-parallel planar surfaces. The planar surface of the top end is inclined to allow for proper mating of the top end of the elevator block with a bed leg in the bed's raised position. Provision is also made for a removable insert in a cavity of the top end of the elevator block, so that bed legs can sit either within the cavity for increased stability or upon the top of the insert, depending upon the size of the bed leg. The use of slip-resistant materials on the surfaces contacting either the floor or bed leg also add to the stability of the bed in the raised position.

  • Patent number: 5222979
    Abstract: A shaped block that can be used for chiropractic treatment. The block has a base, a rear end face, an upper face parallel to the base and merging with the upper edge of the rear end face, a rectangular front end face merging with the front end of the base, and an upper oblique portion between the upper face and the front end face inclined between 60.degree. to 85.degree.. The oblique portion has a first upper inwardly curved section descending from an inner edge of the upper face, an intermediate flat face portion following the first curved section and raised above the plane of the oblique portion, and lifted 7.degree. to 9.degree. at the lower end, and a lower curved section between the intermediate flat face and the second end face. Irregular faces connect these parts together into a block. The faces of the curved section are anti-skidding so as to engage human body portion under treatment while preventing it from sliding along the curved surfaces. The block is made of soft rubbery material.
