Abstract: According to the invention, there is provided a damper for a flapdoor that does not show any damping effect when its movable shaft of the damper is rotated with the door in one sense whereas it effectively damps the rotary movement of the flapdoor when the movable shaft is rotated with the door in the other sense, wherein a one-way clutch for engaging or disengaging the movable shaft with a movable member depending on the sense of rotation of the movable shaft to cause a viscous shearing drag in the viscous fluid contained in the damper and a power source constitute so many integral parts of a coil spring. A damper for a flapdoor having such an arrangement can have a simplified configuration as compared with a damper provided with a separate coil spring as power source and a separate one-way clutch and therefore can be realized with reduced dimensions.

Abstract: According to the invention, there is provided an ingenuously contrived mechanism for controlling the travel of a movable structural member along rails comprising a pair of traveler devices removably engaged with the respective rails and a pair of travel controller that dampen the force pulling the movable member back into the fixed member. With such devices, the movable member can be easily separated from and returned to the fixed member that houses it without requiring any particular operation. Such a mechanism is particularly suited for a cabinet drawer.

Abstract: According to the invention, there is provided a door hinge comprising a spring that plays the role of both a torsion spring and a compression spring, wherein its resilient force is used for axially pressing a movable cam against a matching fixed cam it comprises and thereby facilitating the opening and closing motion of the door with which it is used by giving said cams such specific configurations that the spring accelerates the opening motion of the door from a given angular position of the door and locks the door at a particular open position and at a closed position.

Abstract: A cabinet lid stay is provided including a pair of arms pivotally coupled with each other for relative angular displacement at first ends of the arms and the second end of one arm is pivotally connected to a stationery cabinet portion through utilization of a damper construction while the second end of the second arm is pivotally connected to the cabinet lid through utilization of a pivot connector including a twist lock connection with a fixture mounted to the cabinet lid, the twist lock connection between the second arm and the fixture defining a relative rotation pivot axis of release therefore disposed in the plane of the arms. In addition, the first arm and mounting therefore to the stationery cabinet portion includes coacting structure by which pivoting movement of the first arm relative to the stationery cabinet portion may be adjustably limited to thereby limit the angular positioning of the cabinet lid when in its full open position.

Abstract: There is provided a lift coat hanger comprising an ingenious damper that can be selectively operated with a view to decelerate the rotary motion of the arm and softly stopping it as it comes to the open or closed position, while the construction of the overall lift coat hanger is made rather simple and hence can be realized at a reduced cost.

Abstract: A damper comprising within a casing filled with viscous fluid a number of movable discs to be moved in response to the transmitted external force and a number of not interlocked fixed discs arranged in an alternative arrangement, wherein both movable and fixed discs are axially deflectable can maintain even clearances between the movable and the fixed discs due to the alignment effect of the discs without undergoing unreasonable stress that can damage the discs. The allowable limit of deflection of the fixed and movable discs can be made adjustable so as to modify the total drag of the damper. Sources of resilient restoring force may be provided to enhance the capability of adjustment. Moreover, the number or the size of the movable and/or the fixed discs can be made alterable to effectively modify the drag of the damper.

Abstract: There is provided a slide rail assembly, comprising an elongated inner rail and similarly elongated outer rail each having a U-shaped section and a pair of rounded lateral edge portions arranged vis-a-vis with the corresponding respective lateral edge portions of the other rail as well as a plurality of revolving bodies held between the juxtaposed rounded edge portions of the inner and outer rails, wherein the inside of said juxtaposed rounded lateral edge portions have a radius of curvature which is identical with that of the revolving objects so that the latter are arranged freely revolvably between the juxtaposed lateral edge portions with an appropriate space provided between any two neighboring revolving objects and each of the inner and the outer rails further comprises an intermediate rounded grooves running along the longitudinal axis of the rail to hold a number of intermediate revolving objects between the pair of intermediate rounded grooves, the inside of said rounded grooves and said intermediate

Abstract: The hinge is particularly adapted to permit a relatively thick door to be swung open without interference from the surrounding door mounting frame. A pair of arms pivotally connect the door to the frame, with the inner end of one of the arms being mounted on pin means having an axis about which the door rotates. Through the provision of various embodiments of connecting means and guide means, the pin means connecting the inner arm to the body travels in an arcuate, outward path when the door is opened, thereby moving the plane of the entire door outwardly to permit the room necessary to accommodate essentially full opening of the door. The pin means, during its arcuate movement, is guided by various forms of guide means to precisely define the arcuate path of travel.

Abstract: A stopper which has a rod projected from the lower end opening in a hollow body to be slidable in upward and downward directions and mounted to be urged by the lifting force of a spring, a pedal attached to the rod, and an actuator formed symmetrically with recesses and rotatably supported to one side of the rod. The body is formed with a guide slot 8 adapted so that the actuator is disposed in a predetermined direction slidably in upward and downward directions therein, a rotary controller for rotating the actuator in a predetermined angle, and a connector for engaging the actuator at a predetermined angle, the rod formed to be able to be axially contracted and elongated and returned. Thus, the stopper can lock and release the lock merely by depressing the pedal, thereby improving the operability and permitting locking in a predetermined stroke.

Abstract: A double panel sliding door arrangement where the two panels will lie in one plane when shut, said arrangement comprises upper and lower rails disposed on upper and lower wall portions of a door mounting frame to laterally move and guide right and left door panels by means of rollers provided at the upper and lower ends of the right and left sliding panels. The rails each have at the right and left sides thereof an oblique portion bent backwards, a rail switching portion and a guide portion in such a manner that one panel can be shifted beforehand, and to switch the rail. The sliding panels can be fully closed without a gap between the panels with only one rail without the necessity of chamfering the inner ends of the panels.

Abstract: A stopper for a caster which has a push-button slidably inserted into a mounting hole radially perforated at a frame for journaling wheels, and a stopper rotor so mounted rotatably in parallel with an axle at the push-button as to be elastically urged by a spring in an outward direction and for stoppers formed at the ends thereof on the peripheries of the wheels. An actuator is formed at the stopper rotor, and a cam groove is formed in the mounting hole of the push-button for stepwisely engaging the actuator by the pressing operation of the push-button and the recoiling operation of the spring. Thus, the wheels can be readily locked and unlocked effectively with only one push-button repeatedly operated in pressing the push-button.
