  • Patent number: 8061776
    Abstract: A walk-in and folding apparatus for a seat includes a locking link installed on a cushion frame by an elastic hinge, and connected with a locking unit via a first wire so as to, upon rotation, release the locked locking unit, and a walk-in pin installed on a frame of a seat back by another elastic hinge, protruding towards the locking link so as to, upon folding of the frame of the seat back, force the locking link to rotate, and connected with a folding lever in such a manner as to rotate in association with the same so as to, upon a folding action caused by operation of the folding lever, rotate so that it does not interfere with the locking link.

  • Patent number: 5727403
    Abstract: A revolving shaft disposed at a bottom of a stationary tub has first axial grooves. A washing tub revolvable on the revolving shaft has a spiral guide groove formed at its lower inner surface. A pulsator is rotatably mounted on a bottom in the washing tub. The pulsator has guide projections which are formed on its outer side of the pulsator and guided along the guide groove of the washing tub, and has second axial grooves which are spline-engaged with the first axial grooves of the revolving shaft. A variable pulsator is disposed on the pulsator of the revolving shaft, and has third axial grooves spline-engaged with the first axial grooves and a compressed spring therein so that the bottom of the variable pulsator is tightly contacted with a top of the pulsator by its elasticity. When the revolving shaft is revolved, the bottom of the variable pulsator is moved up and down depending on the upward and downward movement of the pulsator, so that the variable pulsator is expanded and shrunk in width.

  • Patent number: 5680779
    Abstract: Described is a washer having a driving unit which is installed at the lower portion of a rotation axis and rotates the rotation axis, a feed unit which is axially connected to the rotation axis and moves up and down as the rotation axis rotates, and a wash plate which is fixedly installed at the upper portion of the feed unit and has an up-and-down motion as the rotation axis rotates. An up-and-down motion of the wash plate enables even distribution of a heart-type water flow, which then contributes to the prevention of tangling of wash articles at the central portion of a wash tub as well as clinging of wash articles to a pulsator. By using a washer of the present invention, increased washing efficiency can be expected.
