The hinge comprising at least one leaf part mounted to a movable leaf and equipped with at least one hinge axle or seat and at least one frame part mounted to immovable frame and equipped with at least one seat or hinge axle characterized in that the hinge axle (6) has a cross-sectional mushroom shape inscribed in a circle, a seat (7) has a cylindrical shape with the longitudinal channel and the channel shape corresponds to the shape of the stem of mushroom-shaped hinge axle (6) and the radius of the cylindrical seat (7) corresponds to the radius of the circle described on the mushroom-shaped hinge axle (6).

Provided is a torque hinge which can be easily assembled. A torque hinge includes a restricting member 3 having a hole 31, a shaft 4 passed through the hole 31 of the restricting member 3, a friction member 6 engaged with the shaft 4 in an interference fitting state so as to generate torque due to friction to the shaft 4 which relatively rotates and fitted in the hole 31 of the restricting member 6, and a fixing shaft 41 for unrotatably fixing the friction member 6 to the restricting member 3, the fixing shaft 41 intervening between the friction member 6 and the restricting member 3. The fixing shaft 41 presses a wedge-shaped rotation locking portion 44 of the friction member 6 onto an inner surface of the hole 31 of the restricting member 3.

A threaded bolt for a hinge arrangement includes a cylindrical main body. On an outer circumferential surface thereof the cylindrical main body has a first frustoconical projection and a second frustoconical projection, which adjoins the first frustoconical projection. The diameter of a side of the first frustoconical projection that faces toward the second frustoconical projection is smaller than the diameter of a side of the second frustoconical projection that faces toward the first frustoconical projection. The first frustoconical projection comprises at least one tooth on its outer circumferential surface, which tooth protrudes radially beyond an imaginary continuation of the second frustoconical projection.

A door system for a processing machine, including a secondary frame having a stop, a door with a leaf and a shaft mounted movable in rotation about a tilting axis on the secondary frame between a closed position where the leaf extends vertically and an open position where the leaf extends horizontally and where, in the closed position, the shaft is in the lower portion of the leaf, and where the shaft has on its periphery, a protrusion, where in the closed position, the protrusion is not pressed against said stop and where, in the open position, the protrusion is pressed against said stop.

An omni-directional connection assembly broadly includes a hinge pin and one or more connection brackets. The hinge pin comprises a base section, a pair of primary walls, and a pair of opposed projections. The primary walls form a primary slot therebetween for receiving an engagement portion of a first panel therein. The opposed projections are spaced from the primary walls and form elongated passageways for allowing the primary walls to bend slightly outward for receiving the engagement portion of the first panel. The connection brackets are U-shaped for being positioned over the hinge pin and including flanges for attaching the connection brackets to a second panel. The first and second panels are then connected together at angles of between 0 and 180 degrees or more.

A rotary shaft link device has a simplified structure occupying less room and is easy to assemble and includes a transmission unit disposed on a first shaft, a reaction unit disposed on a second shaft and a link unit disposed between the transmission unit and the reaction unit. Two ends of the link unit are formed with driving sections engaged with the transmission unit and the reaction unit. The link unit is assembled in the rail of the restriction plate. When the first shaft is rotated, the link unit responsively moves from a first position to a second position to drive the reaction unit and the second shaft to synchronously rotate. According to the specification of the product, the number of the link devices can be easily adjusted to achieve the object of modularized assembly.

A self-aligning pin. The pin has a shaft and a curved end section with the diameter of the shaft and the curved end section being equal to one another.

A hinge construction includes a hinge bracket that includes a hinge pin supporting plate and at least one opening extending through the hinge pin supporting plate. Also included in the hinge construction is a hinge pin that is held at the at least one opening. The hinge pin includes a hinge pin outer surface, a hinge pin bore extending through the entire length of the hinge pin and a hinge pin slot extending along the entire length of the hinge pin from the hinge pin outer surface to within the hinge pin bore. The at least one opening can be tapered, and the hinge pin outer surface can include a hinge pin outer surface first portion that also is tapered so as to be congruent with the at least one tapered opening. The hinge construction allows elements such as electrical wiring to be routed through the hinge construction.

A furniture connector connects two or more pieces of furniture together or may connect furniture to a wall, embodied, for example, as an adjustable room partition or modular storage unit. The furniture connector has a first spoke and a second spoke, which may be connected to a furniture piece or wall via respective locking mechanisms. The first and second spokes are joined by a pin, along a longitudinal axis of the pin. The connector allows the positions of two attached furniture pieces (or a furniture piece and a wall) to be adjusted about the longitudinal axis at a variety of discrete angles; once set to a desired angle, the connector limits the relative rotational movement of the first spoke and second spoke (about the longitudinal axis.) Other embodiments are also described and claimed.
