Abstract: A synchronous movement device applied to dual-shaft system includes a first shaft and a second shaft, which are assembled with each other and synchronously rotatable. The synchronous movement device further includes a driver disposed on the first shaft and a reactor disposed on the second shaft and a link unit connected between the driver and the reactor. When the first shaft drives the driver to rotate, the driver pushes the link unit to move along the first and second shafts to forcedly push the reactor to rotate in a direction reverse to the moving direction of the driver. Accordingly, the first and second shafts are synchronously rotated.

Abstract: A parallelism control device applied to dual-shaft system for fixing the parallelism of the rotary shafts and facilitating the assembling process. The device includes an assembly of a first and a second rotary shafts and a fixing unit capable of providing torque effect. Each of the first and second rotary shafts has a fixed section and a pivoted section mounted on an electronic apparatus. The fixing unit has a substantially C-shaped cross section and includes a first and a second sections, a connection section in connection with the first and second sections and a split between the first and second sections. The first and second sections and the connection section are fixedly assembled with the pivoted sections of the first and second rotary shafts so as to avoid deflection of the first and second rotary shafts and fix the parallelism thereof.

Abstract: A transmission stabilization device applied to dual-shaft system for stabilizing and smoothening the transmission and reducing wear of the components. The transmission stabilization device includes a first rotary shaft, a second rotary shaft and a transmission unit, which are assembled with each other. Each of the first and second rotary shafts has a fixed section mounted on an electronic apparatus, a pivoted section assembled with a torque module and a connection section. The transmission unit is drivingly engaged with the connection sections. The transmission unit is mounted on a fixing shaft. When the first or second rotary shaft rotates, the transmission unit is moved along the fixing shaft with the rotation of the first or second rotary shaft. The transmission stabilization device can prevent the transmission unit from swinging so as to overcome the problem of retardation of transmission of the conventional device.

Abstract: A locking hinge assembly for an injector is disclosed. The injector includes a forward handle member, a rear handle member and a hinge connecting the first and second members and defining an axis of rotation. The locking hinge assembly includes a hinge element slidable along the axis of rotation between a locked position and an unlocked position. The hinge element is coupled to the forward handle member and the rear handle member at the hinge, and the hinge element includes at least one groove. Additionally, a locking element is provided and positioned about the hinge. The locking element is configured to be received in the groove such that rotation of the forward handle member and rear handle member about the axis of rotation is prevented when the hinge element is in the locked configuration.

Abstract: A hinge has a guiding component, a sliding component and a pivoting device. The guiding component has a base and a track. The base has a top, a free end, a pivoting end and a pivoting portion. The pivoting portion is formed on the pivoting end. The track is mounted on the top of the base near the free end and has two wings. The wings protrude out respectively and traversely from the track. The sliding component is slidably mounted around the track and has a bottom and two recesses. The recesses are formed on the bottom of the sliding component, are opposite to each other and are respectively mounted around the wings. The pivoting device is pivotally mounted to the pivoting portion of the guiding component. Therefore, the guiding component is mounted slidably on the guiding component and pivotally to the pivoting device.

Abstract: An automatic closing door hinge, an automatic closing door mechanism, and a hinge of the automatic closing door mechanism, for smoothly opening a door or closing, with damping, a door. For example, an automatic door closing mechanism has a hinge having a pair of wing plates one of which has a cylinder in a circular cylindrical form received therein a piston, the other wing plate fixing an upper portion of an operation rod engaged with the piston, the piston being to be advanced and retracted through the operation rod associatively with a rotation of the other wing plate. The automatic closing door mechanism comprises a cam formed on the piston. An engaging part provided in the operation rod and movable in the cam. The cam and the engaging part engaging between the piston and the operation rod. A sphere arranged in a recess formed in an outer surface of the piston. A recess groove formed lengthwise in the cylinder. The sphere rolls along the recess groove, to allow the piston to slide within the cylinder.

Abstract: A self closing gate comprising a pair of first and second parallel and spaced vertically extending stationary posts. The gate is mounted between the posts for rotation about the first post between positions closing the space between the posts and opening the space. A pivot assembly is mounted on the first post between one end of the gate and the first post, the pivot assembly comprising an outer rotatable housing tube and a stationary and vertically extending shaft. A stationary housing tube is mounted below and aligned with and for supporting the rotatable housing tube, the bottom annular edge of the rotatable housing tube and the top of the stationary tube being at a bias so that when the gate is opened it will rise. Gravity will close the gate when released.

Abstract: An improved automatic door closure is provided for a door which has a door post mounted by two or more members attached to a door jamb. The door closure comprises a roller which is mounted on the door jam, a cam which is mounted on the door post so that it will rotate with the door post but is capable of limited movement relative to the post in an axial direction, and a spring for urging the cam against the roller as the door is swung between open and closed positions. The cam is contoured so as to cause it and the roller to coact with spring arranged to cause the door to return from open to closed position without any operator applied force. In a preferred embodiment of the invention, the door closure apparatus comprises a compression spring for urging the door to close, and an adjustable mechanism for varying the force exerted by that spring.

Abstract: A swinging door hinge assembly comprises a primary hinge and a secondary hinge. By way of an axle rotating on a staircase-shaped axle seat in the primary hinge, the door can be opened in either direction, slowly closed, or opened at a wide angle for a long time. The secondary hinge includes an inner and an outer eccentric axle bushing by which the secondary hinge can automatically adjust its axis to be in alignment with that of the primary hinge, i.e., in a co-axial alignment in case of the door hinge assembly generating any eccentric condition. Otherwise, the door cannot be operated smoothly in case the two hinges are not co-axially aligned. The door hinge assembly may be easily assembled or disassembled, between the left and right side primary hinge pieces, and also between the left and right side secondary hinge pieces.
