  • Patent number: 6163924
    Abstract: A swivel caster assembly is provided with a releasable locking mechanism which selectively locks the caster assembly against rotation. A leg bushing used to support the leg of an associated appliance such as a baby stroller is rotatably supported by a caster body. The caster body has an upwardly extending locking lug recess, a transverse access aperture passing through the recess, and a transverse axle aperture. A locking lug is slidably received within the recess, and is maneuvered to a fully extended locking position and a retracted unlocking position by an arm member pivotally secured to the caster body. Force transfer between the arm member and the lug is through a spring. A locking collar is secured to the leg bushing and has a downwardly opening notch for engaging the upper end of the locking lug when extended. A pair of detent bosses extend outwardly from the caster body and engage with detent apertures formed in the arm member.

  • Patent number: 6094780
    Abstract: An ergonomic tool handle (21) which is useful for a terminal insertion hand tool, gardening hand tools, knives, box cutters, screwdrivers and other pushing or pulling type hand tools. The tool handle (21) of the present invention is contoured to promote neutral posture between the hand and wrist as well as complementing the shape of the closed hand to distribute longitudinal tool forces evenly throughout the hand and arm of the user. The tool handle (21) accomplishes this neutral posture and contoured fit by featuring a humplike crown (28) which fits snugly into the pocket of the palm, a relatively flat underside (29) around which the user's finger tips (55-57) are wrapped and two sides (51, 52) with convex regions (30, 31) in diagonally offset relation. By moving one's hand up or down the tool handle (21), one size of tool handle (21) can ergonomically fit approximately 95% of male and female hand sizes.

  • Patent number: RE37190
    Abstract: A universal handle for household and other hand-held implements, the handle being adapted to ergonomically render the implement to which it is applied useable by individuals who have difficulty in firmly grasping a conventional handle. The universal handle, which is fabricated of elastomeric material having good thermal insulation and cushioning properties, includes an internal cavity to socket the core shank of the implement. The handle has an elliptical cross section, the opposing sides of the handle adjacent its upper end each having a concave depression, in each of which an array of spaced, flexible fins is anchored to define a depressible grip site. When the fingers of a user's hand are clenched about the handle, the internal region of the resultant fist conforms to the form of the handle to provide a good grip thereon, the thumb and forefinger pressing into the grip sites to enhance the user's grip on the handle.
