Abstract:
A hinge unit applies resilience differently according to the angle at which the hinge unit is opened, and an image forming apparatus has a cover attached by the hinge unit. The hinge unit includes a lower frame connected to a scan unit of a main body of an apparatus; an upper frame engaged with the lower frame through a hinge shaft and connected to a cover; and first and second resilient members serially arranged within the upper frame. When the cover pivots toward the scan unit at less than a predetermined angle, the hinge unit provides relatively minor resistance, whereas when the cover pivots toward the scan unit at the predetermined angle or greater, the hinge unit provides relatively greater resistance, thereby appropriately coping with the moment by weight of the cover. As a result, the improved hinge unit may enable a user to open and close the cover more comfortably.
Abstract:
A hinge mechanism includes a shaft (1), a cam follower (12), a cam (2), an antifriction member (3), a washer (4) and an elastic member (5). The cam follower is fixed relative to the shaft and has a cam follower surface. The cam has a cam surface (24) and a cam hole defined therein. The cam is rotatable relative to the cam follower. The shaft runs through the cam, the washer and the elastic member, in turn. The antifriction member has one end touching the cam and an opposite end touching the washer. The cam surface abuts against the cam follower surface due to the elastic force of the elastic member. As the friction coefficient between the antifriction member and washer is smaller than that between the cam and the washer, the hinge mechanism generates a smaller friction therebetween, so the waste of energy is very small.
Abstract:
Damper for movable furniture parts with a housing and a cylinder disposed in the housing, in which a piston with a piston rod is movably supported therein, with at least one set of gears supported movably on the housing, via which the cylinder and/or a stop for the piston rod can be adjusted relative to the housing.
Abstract:
The invention concerns a cabinet hinge with an automatic opening device, especially for cabinet doors with a hinge cup, which is connected with a hinge to a hinge arm, which is, being adjustable and lockable, connected to a base plate, which is connected to a cabinet body; whereby, the hinge includes an inner and outer joint lever, which are fastened to the hinge cup, as well as the hinge arm, with each one pivoting joint pin, which causes a kind of parallelogram-joint to be formed between the hinge cup and the hinge arm, by which means the cabinet door relative to the cabinet body can be swung out; whereby, at least one elastic resilient spring element directly affects at least one joint pin of outer and/or inner joint lever and causes a torque for opening of the cabinet door from the closed position through a defined opening-angle area, and; whereby, the resilient spring element is fastened to the hinge cup, whereby, at least one resilient spring element affects through a sliding wedge directly or indirectly at least one join pin of the outer and/or inner joint lever. Specifically, the spring element is contained totally inside the hinge cup and includes at least one one-step piston rod-cylinder unit, which allows a relative movement of the sliding wedge towards the hinge cup and its top part during the opening process of the door by means of a spring and during the closing process by means of the strength of the user. The advantage of the spring element position on or in the hinge cup is that considerably more room is available for a heavy spring and heavy doors can be equipped with the automatic opening device, according to the invention.
Abstract:
A closure assembly (40) of an opening in a building including at least two mutually pivoted panels (41, 42, 43) mounted with the mutual pivot axis (44) at least substantially vertical. The panels are movable between a closed condition whereby the at least two panels at least substantially in mutual alignment provide at least a partial closure of the opening in or substantially parallel to the plane of the opening, and an opened condition whereby the at least two panels, mutually disaligned by having pivoted mutually towards each other, are substantially clear of the plane of the opening. A proximate panel (41) is pivoted by a vertical pivot axis substantially in the plane of the opening at adjacent a vertical periphery of the opening (45). The distal region of distal panel (42) is supported by at least one supporting runner. The supporting runner is guided by a support track (51) which is skewed with respect to the plane of the opening and has the affect of spacing the supporting runner out of the plane of the opening at the vertical periphery.
Abstract:
Parallel plane rotation hinge for a portable device. The hinge includes a pin defining a rotational axis and a cam having an inner cam track and an outer cam track. A bushing is rotationally fixed and axially slidable with respect to the pin, and includes inner and outer followers for respectively rotationally engaging the inner and outer cam tracks. A biasing member is disposed about the pin to bias the bushing against the cam.

Abstract:
A hinge assembly for a door of a kimchi storage device is disclosed. The hinge assembly has a support member 60 including a first contact surface 62a sloping down on the upper surface thereof and a second contact surface 62b sloping down thereon next to the first contact surface 62a and prevents the door 5 from coming off the upper surface of the body 6 of the kimchi storage device by maintaining the closed position of the door tightly and prevents cold air leakage by maintaining a sealed state. Also, in an embodiment of the present invention, a hinge housing 70 has a guard portion 71 formed at an upper end portion thereof, the guard portion 71 having an inwardly curved shape and being extended from the upper end of the hinge housing 70 toward inside of the turn member 20, thereby covering a gap formed in a conjunction area between the hinge housing 70 and the turn member 20.
Abstract:
A hinge member includes a rotatable cam element with a first cam face and a slidable cam element with a second cam face associated with the first cam face in such a manner that the second cam face moves away from the first cam face when the slidable cam element is cammed by the rotatable cam element due to an applied external force. A biasing member is connected to the slidable cam element so as to accumulate a returning force when the second cam face moves away from the first cam face and so as to urge the second cam face to move toward the first cam face when the external force ceases to be applied on the rotatable cam element.
