Abstract: A planar assembly support includes a pillar and bed fixable on a surface. A bed center hole is provided with an inner screw thread. An inner locking member has a protruded retaining ring and an outer screw thread on a lower portion outer peripheral face, and fixedly locks on the bed via a threaded connection with the inner screw thread of the bed. The outer screw thread may consist of at least two sections of a convex spiral constituting less than a complete revolution. The pillar and inner locking member can be dismantled together from the bed. The bed left on the surface occupies a smaller space and, therefore, reduces the risk of tripping, while providing convenient mounting and dismantling without damage to the surface. A lock/release mechanism may be provided to prevent inadvertent rotation of the pillar in an unscrewing direction with respect to the bed.

Abstract: A sliding and swiveling device includes a mounting plate, a moving seat, a moving assembly, and a rotating assembly. On the moving scat is provided an inner annular-toothed portion. The rotating assembly includes a fixedly toothed sleeve, a movably toothed ring, a first protruding strip, a camshaft, etc. In the toothed sleeve is provided an annular-toothed portion. On the toothed ring is provided an annular-toothed portion, and the upper surface thereof is provided a protruding pillar. The first protruding strip and camshaft are fitted on the mounting plate, which can be engaged each other or not. The mounting plate can freely rotate in twenty locking positions within 360 degrees around the toothed sleeve. Because the camshaft is also positioned on the mounting plate, the sliding and turning of the chair are both operated in the same place along with the movement thereof, thus it's convenient for users.

Abstract: A seat assembly featuring a seat support assembly having a seat mount assembly and a pedestal post assembly which pivotally supports the seat mount assembly and includes a first component and a second component with the second component being adjustable in height with respect to the first component. The seat support assembly includes a rotation locking assembly with a releasable rotation lock which locks the seat mount assembly from rotating with respect to the pedestal post assembly. Also included is a rotation prevention device or arrangement that is supported by the pedestal post assembly and acts to prevent relative rotation between the first and second components while not interfering with height adjustability between the first and second components. In a preferred embodiment, the first and second components are part of a fluid spring system which has an air spring that varies in height by way of a fluid cushion.

Abstract: A support stand, support stand assembly, and method of making the same with the support stand featuring a base with central hub-like reception area either capped or uncapped at its bottom and a supporting rod that has a diameter less than that of the side wall defining the reception area so as to form an annular gap. An elastomer material, which is preferably a liquid urethane that cures at room temperature, is poured into the gap so as to form an energy management member which acts as a flexible cushioning element by helping to dampen and diffuse rocking forces of the supporting rod with respect to the base. The energy management member also acts to glue the supporting rod to the base through the bonding properties.

Abstract: A plug-in-lock assembly particularly useful for locking in fixed position a pleasure boat seat with respect to the deck of the boat. The plug-in-lock assembly features a base assembly and stem combination. The base assembly features a base within which is formed a reception cavity and a bushing ring supported by the base and extending into the reception cavity. The bushing ring has an interior surface which contacts with the stem once inserted. The base assembly also includes a center post positioned within the reception cavity and supported by the base. The center post has a top surface and a side wall with the side wall being spaced from an interior surface of the base defining the reception cavity so as to define a stem reception gap between said wall and interior surface. The invention also features a method for assembling the plug-in-lock assembly.

Abstract: An apparatus which includes a swivel base formed of a first plate and a second plate. The first and second plates each have a central aperture which is defined by a hook-shaped section of the second plate which extends over an interior edge of the first plate defining the first plate's central aperture. The hook-shaped section is preferably circumferentially continuous and fixes the first and second plates together while allowing for sliding engagement between the first and second plates. Bearing members, such as circumferentially spaced ball bearings, are provided externally to the hook section and between the plates to facilitate sliding and load distribution. One of the plates includes hollow reception ports for holding the bearing circumferentially in place with respect to that plate while the opposite plate has a continuous riding ring in which the bearings are free to rotate.

Abstract: A pedestal for receiving and fixing a shaft having a main body that has an upper reception portion and a lower base portion. The upper reception portion includes at least one side wall which defines a reception cavity for receiving the shaft. The side wall of the upper reception portion includes a gap which extends axially and a first and a second web positioned to opposite sides of the gap and on an interior surface of the side wall. The side wall includes a through-hole extending from the interior surface of the side wall and opening out an exterior surface of the side wall. The pedestal further includes a gap closing member which is supported by at least one of the webs and extends across the gap and is accessible by way of the through-hole such as via one end of the closing member.

Abstract: A sliding and swiveling device that includes a sliding plate having a surface for supporting an attachment unit such as a chair and two laterally spaced sliding portions. The device further includes a holder which has a pair of laterally spaced sliding sections that are in a sliding relationship with respect to the two sliding portions of the sliding plate. The holder also includes a sleeve portion which is dimensioned for receiving a sleeve member in a swivel relationship. The device also features a first locking assembly for releasably locking the sliding plate and holder against rotation with respect to the sleeve member. A second locking assembly is provided for releasably locking the sliding plate and holder against longitudinal sliding. The device features a handle member and an assembly for triggering a release of the first locking assembly upon adjustment of the handle member in a first direction (e.g.

Abstract: A kind of SWIVEL AND SLIDE assembly including a Slide Base, Swivel Part, Slide Part, Lock Part, and Channels at both sides of the Slide Base. The Swivel Part includes a first Swivel Base and a second Swivel Base. The first Swivel Base includes the Slide Feet extending into the Channel, the female circle of the Ring Part, the Lunar Groove and the Pedestal. The second Swivel Base includes the male circle of the Ring Part, the Lunar Groove and the Swivel Lock Slots. Overlapping of the male circle and female circle is fixed by the rolling balls. By installing a Lock matched with the Lock Slot the swiveling can be started or stopped. This invention provides well distributed pressure when swiveling, easy operation, and reliable lock.

Abstract: A transparent shoe box has a box body proper and a box cover. All box bodies and box covers are made of transparent plastic. At the edge of one side, the box body and the box cover are joined together, forming a connecting overlapping edge. In a preferable design, along the center-line of the bottom of the box body and the box cover, there is one or more cylindrical protruding members. In addition, there are two shoe-holders corresponding basically to the size of the feet of the shoe users. Each of the shoe-holders includes a shoe-prop and a protruding or raised part. At the end surface of the protruding or raised part there is a polygonal recess. The shoe-holders can, by dint of the recess on the protruding or raised part, be inlaid and firmly mounted on the protruding member located on the bottom of the box proper or on the box cover. Furthermore, each shoe is placed tidily and apart from each other at a certain position specified by the type of box.
