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.

The invention relates to a hinge (10) comprising a pivotable hinge part (12), a fixed hinge part (14) and a biasable spring element, wherein the pivotable hinge part (12) is pivotably mounted on the fixed hinge part (14) about a pivot axis (S) via a bearing (16), and wherein the biasable spring element is arranged on the bearing (16). The invention is characterized in that the spring element is designed as a flat spiral spring (18).

The invention relates to a hinge (10) comprising a swivellable hinge part (12), a stationary hinge part (14) and a tensionable spring element (34), wherein the stationary hinge part (14) is designed with a first bearing (16) as well as a second bearing (18), wherein the bearings (16, 18) have swivel axes (S1, S2) that are offset to one another. According to the invention, the swivellable hinge part (12) is mounted on the stationary hinge part (14) via the first bearing (16) such that it can swivel about a swivel axis (S1), and the tensionable spring element (34) is arranged on the stationary hinge part (14) via the second bearing (18).

A hinge is coupled to a first component and a second component. The hinge supports the second component for movement relative to the first component between a closed position covering an opening through the first component and an opened position displaced from the opening. The hinge includes a first bracket coupled to the second component, a second bracket coupled to the first component, a support link coupled to the first and second brackets, and a control link coupled to the first and second brackets. Rotation of the support link relative to the first bracket causes rotation of the first component relative to the second component and relative to the support link.

Disclosed herein is a refrigerator. The refrigerator comprising, a housing comprising a storage compartment, a door configured to open or close the storage compartment, a rotating bar provided at the door to be rotatable and configured to be located at a first position when the door opens the storage compartment and to be located at a second position lower than the first position when the door closes the storage compartment, and a guide part provided at the housing and configured to guide rotating of the rotating bar.

The present invention discloses anon-power driven window capable of adjusting ventilation rate. When the sash is unlocked, due to combined action of the sash's gravitational torque and the expansion of a torsion spring against the sash, the window keeps open. The window is designed having a bigger size in the lower section below the pivot than that in the upper section. Subject to the outdoor wind blowing, the moment by the outdoor wind tends to shut the window. In addition, the upper screen is installed in the outer side of the pane above the pivot, while lower screen is installed to the inner side of the pane below the pivot. Thus the lower sash is exposed into the outdoor air and can be easily blown by the outdoor wind. Consequently, the stronger is the outdoor wind, the smaller is the effective opening of the window for ventilation, and vice versa.

A foldable pet apparatus has a rigid platform member, a rigid barrier member, and a support member. The rigid barrier member is attached to one end of the rigid platform member by a hinge. The support member is attached to the rigid platform member at its other end with a hinge. The support member may be attached to a vertical wall below a pet door opening. When the foldable pet apparatus is in a deployed position, the rigid platform member provides a place for a pet to stand after it passes through the pet door. The rigid barrier member prevents the pet from going straight off of the end of the rigid platform member. The pet must turn to the right or left to leave the platform. When the foldable pet apparatus is in the collapsed position, it blocks the pet door opening.

A spring assembly of a hinge assembly for a closure panel of a vehicle, the spring assembly comprising: a spring support bracket for connecting to a bracket of the hinge assembly; a spring mounted on the spring support bracket, the spring having an output end, the spring for biasing operation of the hinge assembly in order to move the closure panel towards an open position, the spring assembly including a holder mounted on the spring support bracket such that the holder is movable between an engaged position with the output end and a disengaged position with the output end; wherein when the output end is engaged with input end, the spring assembly is mountable to the hinge assembly.

A temperature activated door spring device includes a spring having a coil with a contiguous upper arm and lower arm. The coil includes an inner hinge pin hole and has a circumferential edge sized to mount on the top of a hinge knuckle. A collar is affixed within the inner hinge pin hole wherein the inner hinge pin hole is encompassed by the collar sized to accept an inserted hinge pin. A pellet hole is located proximate an extended end of the upper arm, wherein the pellet hole is sized to accept a fusible pellet. An upper portion of the pellet hole traverses through the upper arm and a lower portion of the pellet hole traverses through the lower arm so that when a fusible pellet is inserted into the pellet hole it holds the upper arm and the lower arm together in a spring loaded position.

A hinged safety gate can include a gate frame and a retainer assembly. The gate frame can have a distal upright member, an upper cross-arm, and a lower cross-arm. The hinged safety gate can have a retainer assembly that is configured to be attached to a proximal end of the gate frame and to hingedly couple the gate frame to a stationary vertical surface, permitting the gate frame to swing between an open position and a closed position. The gate frame is horizontally adjustable in two different manners relative to the retainer assembly to accommodate a range of access area widths.
