A flip hinge for a motor vehicle includes an inner strap affixed to a body of the motor vehicle, an outer strap separate from the inner strap and affixed to a removable panel of the motor vehicle, and an intermediate link extending from the inner strap to the outer strap. The intermediate link is rotatably attached to the inner strap at a first link end by a spring-loaded pivot. The intermediate link is rotatably attached to the outer strap at a second link end by an outer strap pivot. The intermediate link is movable between at least a first position and a second position. The spring-loaded pivot biases the intermediate link towards the second position whenever the intermediate link is not in the first position, and the outer strap is separable from the intermediate link only when the intermediate link is in the first position.

A rebounding pivot module includes a mounting shaft, and a bouncing device set including a barrel having one end tooth shaped, a connecting tube mounted in the other end of the barrel, a connection rod connected to the connecting tube, a socket and a first guide block mounted onto the connection rod, the first guide block having one end beveled, a bouncing barrel mounted around the connecting rod, a second guide block supported on an elastic member in the bouncing barrel and defining therein a guide hole and having one end tooth shaped and abutted at the beveled edge of the first guide block, and a lock device fastened to connection rod that is inserted through the second guide block, the elastic member and the through hole of the bouncing barrel to lock the bouncing barrel to the connection rod.

A dampened hinge assembly has a male leaf and a female leaf. The female leaf has spaced apart first and second end barrels coaxially rotating with respect to a central barrel of the male leaf therebetween. An axial shaft is fixed to the second end barrel of the female leaf at a proximal end of the axial shaft. The axial shaft has a distal helicoidally threaded spindle. A compression gear having a helicoidally threaded bore matching the helicoidal thread of the spindle displaces towards the first end barrel when the leaves move into alignment and towards the second end barrel when the leaves move out of alignment. The dampened hinge assembly may be reconfigured to provide soft closure, end-of-range soft closure and/or backcheck damping.

A door hinge for a laboratory instrument door, the door hinge comprising a hollow body with a first longitudinal axis and a curved side wall comprising a track. At least a part of the track is inclined relative to the first longitudinal axis. The door hinge further comprises a linear guiding element with a second longitudinal axis parallel to the first longitudinal axis. At least a part of the linear guiding element is arranged in the hollow. The linear guiding element and the hollow body are rotatable against each other. The door hinge further comprises a body comprising a protruding pin. The body is movably attached to the linear guiding element so that the body is movable in two opposite directions along the second longitudinal axis and the protruding pin is movable on the track.

An apparatus combining a door hinge and a door closer is provided. In one embodiment, the hinge provides a variable hydraulic damping speed control with spring action closing, as well as an optional stop action. In one embodiment, the hinge of the present invention includes an adjustable compression spring to operate the opening and closing of the door. After the door has closed to approximately 20 degrees or so, the hydraulic component of the door may then control the speed of the door preferably from approximately 20 degrees until closed. The hydraulic component can also be adjusted to vary the speed and force of the door opening and closing. A pair of magnets may be present in the control cylinder of the hinge to provide more force to complete the closing function. Additionally, a stop function allows for the door to remain open and in place in one embodiment.

A self-stowage device may comprise: a housing comprising a slot, the housing having a blind hole disposed in the first end extending to the second end, the housing including an outer surface extending from the first end to the second end, the slot disposed through the outer surface, the slot extending axially and circumferentially about the outer surface; a spring disposed in the blind hole, the spring having a first spring end and a second spring end, the second spring end configured to compress against the second end of the housing; a shaft disposed in the blind hole, the shaft disposed adjacent to the first spring end; and a pin coupled to the shaft, the pin disposed in the slot, the pin and the slot configured to convert a rotary motion of the shaft into a linear motion of the shaft.

The present disclosure is directed to a door hinge mechanism for a vehicle. The door hinge mechanism may include a door configured to open and close relative to the frame, and a hinge secured to an interior of the door and an exterior of the frame. The hinge may be configured to open the door by sliding the door away from the frame and pivoting the door relative to the frame.

The present disclosure a hinge blade structure comprises two hinge blades, a connection sleeve, a fixed rod, a screw sleeve, a plug, a damping positioning pull rod, and an air cylinder. The damping positioning pull rod and the air cylinder are both disposed in the connection sleeve and disposed between the fixed rod and the plug, the air cylinder is relatively secured to the plug, the damping positioning pull rod is relatively secured to the screw sleeve, the damping positioning pull rod is slidably connected to an inner side of the air cylinder along a length direction of the connection sleeve, the damping positioning pull rod and the air cylinder cooperate to define an air chamber, the air cylinder comprises an air chamber vent through hole and an air inlet, and a resistance force generated between the air chamber and the damping positioning pull rod achieves positioning.

A gate unit includes a gate mount adapted to mate with a frame bordering a passageway. The gate mount includes a gate hinge including a stationary pivot support and a movable pivot that is mated in rotative bearing engagement with the stationary pivot support to establish a gate-pivot axis. A gate is coupled to the movable pivot of the gate hinge for pivotable movement with the movable pivot about the gate-pivot axis between a closed position closing a walkway passage formed in the gate mount to block movement of a person through the walkway passage and an opened position opening the walkway passage to allow movement of a person through the walkway passage.

A gate unit includes a gate mount that is adapted to mate with a frame bordering a passageway and formed to include a latch receiver and a gate mounted on the gate mount for pivotable movement about a gate-pivot axis between an opened position opening a walkway passage formed in the gate mount and a closed position closing the walkway passage formed in the gate mount. The gate unit further includes a gate lock configured to lock the gate in the closed position closing the walkway passage formed in the gate mount.
