A document cover closer and office equipment using the same are disclosed. The document cover closer includes an attaching part, which includes an attaching base and two side plates. The attaching part is attached to a main body. A supporting part includes a back plate and two side plates. The side plates of the supporting part are rotatably coupled via a hinge shaft to the side plates of the attaching part. A lift part includes a back plate and two side plates. The side plates of the lift part are pivotally attached via a coupling shaft to the free end side of the side plates of the supporting member. An actuating part is provided on the pivotally attaching portion of the lift part so as to rotate about the coupling shaft when the lift part rotates.

A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. The bottom end includes a knurled outer surface. A stop cam is positioned about the knurled outer surface and has an inner surface that conform to the knurled outer surface so that it may be positioned in a plurality of rotatable positions relative to the central tube. The stop cam also has an exterior surface which includes a detent. The different rotational positions of the stop cam upon the knurled outer surface changes the relative position of the detent in relationship to the central tube. A cam follower assembly is coupled to the lower mounting plate and has a cam follower plate with a cam follower that rides upon the stop cam and engages the detent recess to hold the door in an open position.

A multi-link door hinge capable of facilitating the closing of a door and implementing the shock-absorbing performance of the door during the closing thereof. To this end, the multi-link door hinge includes: a main frame mounted to a main body of an object having a door; a door frame mounted to the door; a body frame rotatably connected to a first side of the main frame; an inner link and an outer link connecting the door frame to the body frame; a plate spring link allowing the outer link to be rotatably connected to the main frame; a locking piece rotatably mounted between side walls of the inner link; an elastic member; and a hook, a first side of which is fixed in the body frame and a second side of which is configured to be held in a second side of the locking piece.

A door security device for an in-swing door includes a mounting plate secured to the door jamb adjacent the door outside edge, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a locking swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked angular positions in relation to the hinge pin vertical axis, the locking swing plate biased by force of gravity to a lowermost position, and the mounting plate having a first receiver wall defining the lowermost position of the locking swing plate in the locked position perpendicular to a first rear surface of the mounting plate and defining the uppermost position of the locking swing plate in the unlocked position away from the locked angular position.

A gate includes a gate barrier, an upper hinge configured to rotatably support the gate barrier about a rotation axis, and a lower hinge configured to rotatable support the gate barrier about the rotation axis. The upper hinge portion may include a first upper hinge portion having a first receptacle and a first ramp disposed adjacent the first receptacle, and a second upper hinge portion having an upper hinge projection configured to engage the first receptacle to inhibit rotation of the first upper hinge portion. The lower hinge may include a first lower hinge portion coupled to the gate barrier, the first lower hinge portion having a receptacle and a lower hinge projection extending from a base of the receptacle, and a second lower hinge portion having an annular projection configured to engage the receptacle and receive the lower hinge projection.

An arm structure of an electronic device is provided. The arm structure includes an arm body, a first cam disposed on one side of the arm body and including a first hole into which at least a portion of a rotating shaft providing a folding operation of the electronic device is inserted, a peak and a valley being formed around the first hole, a second cam arranged side-by-side on a same axis as the one side of the arm body, spaced apart from the first cam, and including a second hole into which at least a portion of the rotating shaft is inserted, a peak and a valley being formed around the second hole, and a connecting part disposed on another side of the arm body and fastened with a rotating part providing rotation of the electronic device.

A tailgate stop apparatus. The apparatus includes a base member configured to be fixed with respect to a primary gate assembly of a multiple-gate tailgate. The apparatus includes a stop member coupled to the base member, wherein the stop member is movable between a tailgate-engaged position configured to inhibit an inner gate panel of an inner gate assembly of the multiple-gate tailgate from being moved to a closed position, and a tailgate-disengaged position configured to allow the inner gate panel to be moved to the closed position.

The disclosure relates to a cooking appliance capable of reducing noise generated when a door is closed using a buffer member that is easily fixed to a hinge unit. The cooking appliance includes a main body, a cooking chamber provided to have a front surface opened inside the main body, a door to open and close the cooking chamber, a hinge unit coupled to the main body to rotatably support the door, and a buffer member fixed to the door to buffer an impact generated when the door is closed by contacting the hinge unit when the door is closed.

Provided is a single-axis hinge with a damper mechanism and a catch mechanism for allowing either one of a first member and a second member to be attached to a portion having a small attachment space. The single-axis hinge (2) includes the first member (11) attached to the main body, and the second member (12) which is attached to the door and can rotate with respect to the first member (11) around a shaft (13) facing a vertical direction. The catch mechanism (6) has a spring (8) and gives rotational force in a closing direction to the door in the vicinity of a closed position. The damper mechanism (7) has a linear damper (9) and damps rotation of the door when the door is closed. The catch mechanism (6) and the damper mechanism (7) are disposed on either one of the first member (11) and the second member (12).

A household appliance hinge includes a mounting portion and a mounting tab including a cam profile. A door mounting lever is pivotally connected to the mounting tab of the mounting portion. A spring-biased control system is connected to the door mounting lever and includes a spring-biased cam follower system including a cam follower that: (i) engages the cam profile in an engagement position and for all positions of the door mounting lever between the engagement position and a first operative position; and, (ii) separates from the cam profile for all positions of said door mounting lever located between the engagement position and a second operative position. The hinge is self-latching.
