Abstract: A rotary damper has a damper body having a receiving portion, and a rotor rotatably disposed in the receiving portion of the damper body. A space between an inner circumferential surface of the receiving portion and an outer circumferential surface of the rotor is divided into a plurality of pressure chambers. A rotation speed of the rotor is controlled to be at a low speed by a flow resistance of fluid filled in each of the pressure chambers when the fluid flows through gaps between an inner surface of the receiving portion and an outer surface of the rotor opposed to each other in a direction of a rotation axis of the rotor. The damper body and the rotor are relatively movable in the direction of the rotation axis of the rotor.

Abstract: Provided is a door opening and closing device that includes: a main opening and closing device body attached to a housing; a mounting member attached to a door; an arm pivotably provided to the main opening and closing device body, the arm applying force to the door via the mounting member in an opening direction and/or a closing direction; a slider provided to the main opening and closing device body to be slidable in one direction; an urging unit for urging the slider in the one direction; a transmission mechanism for transmitting urging force of the urging unit to the arm; and a door restraint link pivotably linked to the arm at a position away from the center of pivot of the arm, pivotably linked to the mounting member, and slidably linked to the main opening and closing device body so that the door moves in a certain manner.

Abstract: The upper end of a cover is provided at the upper end of a hanger body so as to be capable of rotating in the vertical direction. The cover is adapted to be capable of rotating between a closed position at which the cover abuts on the front surface of the hook of the hanger body and an open position at which the cover is rotated upward by a predetermined angle from the closed position. When located at the closed position, the cover closes an upper open section which opens an engagement recess to the outside. An insertion hole (is provided in the cover. The latch of a padlock is inserted through both the insertion hole and the engagement recess. The abutting of the latch against the backward facing back surface of the hook prevents the cover from rotating from the closed position to the open position side.

Abstract: Provided is a hook which is capable of holding multiple objects or an object having a large size of width by efficiently using a space inside the hook, reliably preventing the hanged object from dropping, and allowing the hanged object to be taken out easily. A hook body has a latch that locks an arm biased toward an outside of the hook body by an arm biasing mechanism, and regulates a displacement of the arm, thereby closing an opening portion. While the latch is biased by a latch biasing mechanism so as to face the opening portion and be present at an arm regulating position for locking the arm, the latch is displaced from the arm regulating position against a biasing force of the latch biasing mechanism so as to unlock the arm.

Abstract: In a rotary damper 1 including a cam surface 3f formed in a lower end surface of a large-diameter portion 3b of a rotor 3 and including a cam surface 4f formed in an upper end surface of a piston 4, the cam surface 4f being capable of contacting the cam surface 3f, the cam surfaces 3f, 4f pressed to contact each other by a coil spring 9 biasing the piston 4, the piston 4 is prohibited from being moved toward the large-diameter portion 3b beyond a predetermined second position. Coil spring 9 does not rotationally bias the piston 4. The coil spring 9 biases the piston 4 only such that the piston 4 approaches the large-diameter portion 3b.

Abstract: A toggle type fastener to releaseably couple a fixed object and a movable object to each other includes a pedestal that is structured to be fixed to the movable object, a toggle lever pivotally coupled to the pedestal, a latching arm pivotally coupled to the toggle lever, a looseness prevention element that prevents movement of the movable object. The looseness prevention element is attached to the latching arm and sized to be hooked to a hooked member that is structured to be fixed to the fixed object.

Abstract: Provided is a stay which is capable of stabilizing movement of a component part used for transmitting, or not transmitting, the torque of one of a first member and a second member to the other. When a second member (12) rotates relative to a first member (11) in one direction, a cam base (36) moves away from a disk (34) in the direction of the rotation axis (C), and the second member (12) and the cam base (36) rotate relative to the first member (11) and the disk (34). When the second member (12) rotates relatively to the first member (11) in the other direction, the cam base (36) moves towards the disk (34) in the direction of the rotation axis (C), and the second member (12), the cam base (36) and disk (34) rotate relative to the first member (11) with resistance force.

Abstract: Provided is a door opening/closing device unit which is capable of preventing shifting of the mounting position of a connecting rod to door opening/closing devices and facilitating the mounting work. The door opening/closing device unit has at least one support member 8 mountable on a housing 1, a pair of door opening/closing devices 4 for moving a door 2 relative to the housing 1 and a connecting member 5 for connecting the door opening/closing devices so as to synchronize operations of the door opening/closing devices. First the support member 8 is mounted on the housing 1, and then, at least one of the paired door opening/closing devices 4 connected by the connecting member 5 is mounted on the one support member 8.

Abstract: In a hinge device 1, a door-side mounting member 6 is rotatably connected to a housing-side mounting member 3 via an inner link 4 and an outer link 5. To prevent the inner link 4 and the outer link 5 from being rattled, one protrusion 72 of a torsion coil spring 7 as a rotationally biasing mechanism is pressed against one side plate 41 of the inner link 4 via a cam member 91 and the other protrusion 73 of the torsion coil spring 7 is pressed against the other side plate 52 of the outer link 5.

Abstract: A stowable folding door device includes a slider to move the folded door in a depth direction of an article of furniture, a hook supported by the slider so as to rotate about a first rotation shaft and to engage with an engaging section provided on the article of furniture, and a lever supported by the hook to rotate about a second rotation shaft. Upon folding up the foldable door, the lever rotates in a first direction about the first rotation shaft together with the hook while contacting the rear surface of the foldable door, and the engagement between the hook and the engaging section is released. When the foldable door closes an opening of the article of furniture, the lever rotates relative to the hook in the direction opposite the first direction about the second rotation shaft while contacting the rear surface of the foldable door.

Abstract: The upper end of a cover (6) is provided at the upper end of a hanger body (2) so as to be capable of rotating in the vertical direction. The cover (6) is adapted to be capable of rotating between a closed position at which the cover (6) abuts on the front surface of the hook (2e) of the hanger body (2) and an open position at which the cover (6) is rotated upward by a predetermined angle from the closed position. When located at the closed position, the cover (6) closes an upper open section (2i) which opens an engagement recess (2j) to the outside. An insertion hole (6g) is provided in the cover (6). The latch (Ja) of a padlock is inserted through both the insertion hole (6g) and the engagement recess (2j). The abutting of the latch (Ja) against the backward facing back surface of the hook (2e) prevents the cover (6) from rotating from the closed position to the open position side.
