A hinge includes a first hinge member including a first barrel, a second hinge member including a first end barrel opposite a second end barrel, a spring having a first axially extending end and a second axially extending end opposite the first axially extending end, a spring tensioner having a first depression for receiving the first axially extending end of the spring and a second depression for receiving a driver. A retainer is coupled to the spring tensioner and includes an opening that is penetrable by the driver when the driver is being received in the second depression. A method of adjusting the hinge includes compressing an end of the spring and twisting the same.

A hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

Provided is a hinge that includes a first leaf assembly including a first front leaf component coupled to a first rear leaf component for accommodating therebetween a portion of a panel having a first pair of holes. A first pair of fasteners may extend between the first front and rear leaf components and through the pair of holes in the panel to clamp the portion of the panel to the first leaf assembly. A second leaf assembly, hingedly coupled to the first leaf assembly about a hinge axis, may include a second front leaf component coupled to a second rear leaf component for accommodating therebetween a portion of a second panel having a second pair of holes. A second pair of fasteners may extend between the second front and rear leaf components and through the pair of holes in the second panel to clamp the portion of the second panel to the second leaf assembly. A spring may be coupled to the first and second leaf assemblies to bias the first and second leaf assemblies to move from an open position to a closed position. A dampener having a longitudinal axis may slow movement of the first and second leaf assemblies to the closed position, wherein the longitudinal axis of the dampener is located between the hinge axis and the first panel.

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 door hinge comprising: a frame mount configured to be mounted to a door frame which is disposed about a doorway; and a door mount configured to be mounted to a door which is to selectively close off the doorway; wherein the door mount is pivotally connected to the frame mount about an axis of rotation, and further wherein the door hinge is configured such that when the frame mount is mounted to a door frame, and when the door mount is mounted to a door, the axis of rotation of the door hinge is disposed outwards of the point of attachment of the door hinge to the door frame, and laterally outboard of the doorway.

A damper device includes an outer cylinder, an inner cylinder disposed inside the outer cylinder and having an inner chamber, a lower open end, and an upper closed end wall with a vent hole, a piston disposed in the inner chamber and having a passageway, a check valve coupled to the passageway to permit only upward flowing of a working fluid in the inner chamber through the passageway, and a piston rod having a lower rod end disposed outwardly of the outer cylinder, and an upper rod mounted to permit the piston to slide with the piston rod. The sliding of the piston rod is dampened by sliding of the piston in the inner chamber. A hinge assembly including the damper device is also disclosed.

In embodiments, a hinge includes a first hinge element for arrangement on a closing element and a second hinge element for arrangement on a frame, the first and the second hinge elements being connected to each other to pivot about a hinge axis, and at least one actuating element for adjusting the spacing of the hinge axis relative to at least one of the first and the second hinge elements.

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.

In embodiments, a hinge includes a first hinge element for arrangement on a closing element and a second hinge element for arrangement on a frame, the first and the second hinge elements being connected to each other to pivot about a hinge axis, and at least one actuating element for adjusting the spacing of the hinge axis relative to at least one of the first and the second hinge elements.

A damper device includes an outer cylinder, an inner cylinder disposed inside the outer cylinder and having an inner chamber, a lower open end, and an upper closed end wall with a vent hole, a piston disposed in the inner chamber and having a passageway, a check valve coupled to the passageway to permit only upward flowing of a working fluid in the inner chamber through the passageway, and a piston rod having a lower rod end disposed outwardly of the outer cylinder, and an upper rod mounted to permit the piston to slide with the piston rod. The sliding of the piston rod is dampened by sliding of the piston in the inner chamber. A hinge assembly including the damper device is also disclosed.
