Disclosed is a door device that can ensure necessary catch function and/or assist function and give a neat impression is provided. The hinge includes a first part to be attached to a main body and a second part to be attached to a door. The door device includes a base, an arm rotatably supported on the base and a spring for applying torque to the arm in the closing direction and/or in the opening direction thereof. The base of the door device is attached to the first part of the hinge.

Door device

Provided is a retracting device which can decrease a difference of restoring force of a tension coil spring between a retracted position and a stop position. The retracting device of the present invention includes a base, a sliderwhich can catch a triggerand move from the stop position to the retracted position with respect to the baseand a tension coil spring (B) for relatively moving the sliderwhich has caught the triggerfrom the stop position to the retracted position with respect to the baseto apply force for assisting the closing operation to a sliding door. The tension coil spring (B) is an initially-tensioned spring in which a coil closely contacts and which has initial tension in a direction in which the coil closely contacts when it is in a natural length.

Retracting device

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 rotates relative to a first member in one direction, a cam base moves away from a disk in the direction of the rotation axis, and the second member and the cam base rotate relative to the first member and the disk. When the second member rotates relative to the first member in the opposite direction, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and disk rotate relative to the first member with resistance force.

Stay

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.

Rotary damper and hinge device with damper

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.

Hinge for furniture

In a hinge device, a door-side mounting memberis rotatably connected to a housing-side mounting membervia an inner linkand an outer link. To prevent the inner linkand the outer linkfrom being rattled, one protrusionof a torsion coil springas a rotationally biasing mechanism is pressed against one side plateof the inner linkvia a cam memberand the other protrusionof the torsion coil springis pressed against the other side plateof the outer link

Hinge device

A rotary damper includes a damper body having a cylindrical configuration and a rotor rotatably disposed in the damper body. The rotor is non-rotatably connected to an inner link so that the rotor is rotatable together with the inner link. Two teeth constituting a part of a gear are formed in an outer circumferential surface of the damper body. A tooth of a gear member rotatable together with an outer link is engaged with the teeth. By this arrangement, the damper body and the rotor can be rotated in opposite directions.

Hinge device with damper

A hinge apparatus has a first attachment member to be attached to a housing, a second attachment member to be attached to a door; and first and second links, respective basal end portions of the first and the second links rotatably attached to the first attachment member, respective distal end portions of the first and the second links rotatably attached to the second attachment member. The first attachment member, the second attachment member, the first link and the second link constitute a link mechanism. The first attachment member has a base member to be attached to the housing, and a connecting member removably attached to the base member. The basal end portions of the first and the second links are rotatably attached to the connecting member. The connecting member, the second attachment member, the first link and the second link constitute a link mechanism.

Hinge apparatus and container apparatus

A moveable holder for connecting a moveable member to a stationary member includes two pivoting arms mountable between the members. The moveable member has a position abutting the stationary member and a position spaced away from the stationary member. One of the arms is spring-loaded such that the moveable member is easily urged to either the abutting position or the spaced-away position when the moveable member is located at a neutral position intermediate to the abutting position and the spaced-away position.

Movable holder

A hinge device has a base, a body removably provided at the base, and a mounting member rotatably connected to the body. The base has a base member, a first movable member disposed at the base member such that the first movable member is movable in a first direction and non-movable in a second direction orthogonal to the first direction, and a second movable member disposed at the first movable member such that the second movable member is movable in the second direction and non-movable in the first direction, and the body removably attached to the second movable member. A first position adjustment mechanism is provided between the base member and the first movable member. The first position adjustment mechanism adjusts position of the first movable member with respect to the base member in the first direction.

Hinge device and base for hinge device

One end portion of a connecting memberis connected to a first housingsuch that the connecting memberis rotatable about a first rotation axis L. The other end portion of the connecting memberis connected to a second housingsuch that the connecting memberis rotatable about a second rotation axis Lparallel to the first rotation axis L. The first and the second housingsare arranged such that when the second housingis rotated up to a predetermined intermediate position, opposite end portions of the first housingin a direction perpendicular to the first and the second rotation axes L, Lare protruded from the second housingin the said direction.
