The present invention relates to reliably performing an opening portion operation and a closing operation without using a cam and a member sliding on the cam, by including a body-side member fixed to a box body; a door-side member fixed to a door, a link mechanism connecting the body-side member to the door-side member, and a catch mechanism interposed between the link mechanisms, between the body-side member and the link mechanism, or between the door-side member and the link mechanism, and configured to bias the door-side member in a closing direction or an opening portion direction, wherein the catch mechanism includes a coil spring provided on one side of two members that are connected so as to be rotatable relative to each other through a shaft member, and a transfer arm configured to transfer an elastic restoring force of the coil spring to an other side of the two members, and the transfer arm is connected to be rotatable at a point spaced apart from the shaft member on the other side of the two members.

An appliance lid hinge assembly includes a cam arm pivotally connected a base. A cam arm control system includes a spring rod adapted to move in a sliding reciprocal manner. A spring urges the spring rod toward an extended position. The spring rod is movable toward a retracted position. The cam arm is engaged with the spring rod through a cam follower such that: (i) pivoting movement of the cam arm in an opening direction corresponds with movement of the spring rod from the retracted position toward the extended position; and, (ii) pivoting movement of the cam arm in a closing direction opposite the opening direction corresponds with movement of the spring rod from the extended position toward the retracted position. An optional damper exerts a damping force on the spring rod or other part of the cam arm control system when the cam arm moves in a closing direction.

A back door structure includes a first arm, a second arm, a damper stay, and a supporting member. The first arm is fixed to an upper section of a vehicle body rear section, and is fixed to an upper section of a back door. The second arm is fixed to the upper section of the vehicle body rear section, and is fixed to the upper section of the back door. The damper stay is fixed to the back door, is fixed to the vehicle body rear section, and biases the back door in an opening direction. The supporting member is fixed to the second arm, is fixed to the back door, and biases the second arm substantially toward a vehicle upper side in a fully closed state of the back door.

A device can include a hinge mechanism rotatably coupling a first portion of the device to a second portion of the device. The hinge mechanism is configured to automatically open the device. The device can also include a damper configured to control a rate at which the hinge mechanism automatically opens the device. The hinge mechanism can include a spine hinge, a rolling contact hinge, a film hinge, or a geared link hinge.

The description relates to hinged devices, such as hinged computing devices. One example can include a hinge assembly that rotatably secures a first portion and a second portion relative to a hinge axis and defines a planar conductor path between the first and second portions through the hinge assembly. The example can also include a pop-up arm that compresses a spring when the first portion and the second portion are rotated to a closed orientation, and wherein the compressed spring creates a bias to rotate the first and second portions from the closed orientation to an open orientation.

A hinge device for opening and closing a relatively lightweight cover, as well as office equipment using such a hinge device. A hinge device includes an attaching part attached to the office equipment side, the supporting part attached to the cover side, a hinge shaft for rotatably coupling the attaching part and the supporting part, a slider provided inside the supporting part so as to be slidable in a direction perpendicular to an axial direction of the hinge shaft, a cam portion formed on the attaching part, a cam bearing portion formed on the slider, an urging means for urging the slider toward the attaching member and bringing the cam bearing portion into a pressurized contact with the cam portion.

A vehicle comprising a plurality of walls defining a volume adapted to house passengers and/or merchandise and at least one electric battery pack to supply energy for the operation of the vehicle, said at least one electric battery pack being housed in a respective seat made in at least one of the walls and defining with the latter a housing volume comprising at least one cover configured to assume a first operating position in which the volume communicates with the outside environment and a second operating position in which the volume is isolated from the outside environment; the vehicle comprising security means configured to enable the covers to move from the first operating position to the second operating position when a temperature of the electric battery pack and/or a temperature inside the volume exceed/s a pre-set threshold temperature value.

A hinge is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations. The hinge, provided with a first wing member linked to a first linked object and a second wing member linked to a second linked object, and rotatably linking the second linked object to the first linked object, is provided with a sensor which detects prescribed change in the external environment in the hinge or around the hinge, and a control unit which externally transmits, over a communication network, information on the change in the external environment detected by the sensor, wherein the sensor is configured from at least one of: a rotation speed sensor for detecting the rotation speed of the second wing member relative to the first wing member; a vibration sensor for detecting the amount of vibration; a load sensor for detecting load; an angle sensor for detecting the opening angle of the second wing member relative to the first wing member; a temperature sensor for detecting temperature; and an air pressure sensor for detecting atmospheric pressure.

A hinge for door leaves of furniture and the like, which comprises a fixed part that can be connected to a body of a piece of furniture and a movable part that can be connected to a door leaf of the piece of furniture, the fixed part and the movable part being mutually connected in an oscillating manner by way of an articulation system that comprises at least one articulation axis and a rocker, the hinge comprising elastic means for opening the hinge which are functionally connected to the at least one rocker; the fixed part of the hinge is shaped so that it can be inserted into a seat defined within the thickness of an upper or lower wall of a piece of furniture.

A door hinge device comprises a hinge base and an auxiliary door-closing mechanism mounted on a door and fitted with the hinge base. The auxiliary door-closing mechanism comprises a shell, an elastic member for driving the door to be automatically closed during the door closing process, a sliding member, and a guiding member for guiding the sliding member to move in the deformation direction of the elastic member during the door opening and closing process. One end of the elastic member is connected to the shell, an accommodating part for accommodating the sliding member when the door is in a closed state and a guiding bevel obliquely extending forwards to approach the auxiliary door-closing mechanism are arranged on the periphery of the hinge base in a concave manner, and the sliding member is in a compressed state when moving along the guiding bevel.
