Abstract: A rotary bearing for rotably supporting an article-carrying member at a supporting column of a rotary fitting of a cupboard comprises a supporting member having a first component and a second component movably connected to each other. In a closed state of the supporting member, the first and the second component together define a cylinder envelope shaped inner surface encircling an aperture of the supporting member; and they together provide a circular track at a top face of the supporting member. In an open state of the supporting member, the first and the second component provide an access opening to the aperture that has a width of at least about the diameter of the cylinder envelope shaped inner surface. A pin is fixed at one of its ends to the first component of the supporting member, and it extends from the first component of the supporting member into the aperture.

Abstract: A free-of-bearing rotational positioning device for a dewatering basket of a non-treading type wringer bucket, comprising: a bucket body having a projecting seat being extended from the bottom of the bucket body toward inside; a support shaft being covered and secured by the projecting seat, the upper portion thereof jutting out of the top of the projecting seat to create a connection part; a positioning element having a conic part at the top thereof, the conic part being tapered upward, a positioning surface being formed at the bottom of the conic part and extended outward from the periphery of the support shaft; and a dewatering basket having a driven seat at the center of the bottom thereof. The bottom of the driven seat includes a shaft holder made of non-metal material. In mounting the dewatering basket, the driven seat fits from top to bottom over the connection part of the support shaft.

Abstract: A rotary fitting for a corner cupboard comprises a supporting column; fastening members for the supporting column; an article-carrying member rotating about the supporting column; and a rotary bearing between the supporting column and the article-carrying member. The rotary bearing has a first component mounted on the supporting column and having an upper side with at least three circular tracks that extend round the supporting column, and comprise two opposite sloping regions arranged between a lower portion and an upper portion of the track each, the sloping regions which slope in the same direction of all circular tracks being distributed around the supporting column; and a second component mounted on the article-carrying member and having an underside on which one complementary circular track having lower and upper portions and opposite sloping regions is provided per each circular track on the upper side of the first component.

Abstract: A rotary shelf assembly having a plurality of shelves mounted on a vertical post is disposed in a cabinet frame with upper and lower bearing elements supported at opposite ends of the post and coacting with vertically spaced bearing members which are secured to the cabinet frame to support the post for turning about its longitudinal axis. The assembly is adapted to be mounted in the corner of the cabinet frame and, to accommodate this, the shelves have perpendicular edges which generally align with the sides of the cabinet in one angular position of the post and which support a V-shaped door. To adjust the vertical position in the cabinet frame, the lower bearing element is on a slide in the lower end portion of the post and a manual actuator on the post moves a cam which cooperates with a cam follower on the slide to move the slide and hence the lower bearing member downwardly relative to the post.
