A hinge system for a panel includes a first plate configured for coupling to a structure, a second plate rotatably coupled to the first plate and disposed on a first side of the panel, a third plate disposed on a second side of the panel opposite the first side, and a slider piece disposed within the panel, the slider piece having a first slot disposed therein. The second plate is coupled to the third plate via at least one fastener, wherein the at least one fastener is configured to slide within the first slot of the slider piece such that the panel may translate relative to the second and the third plates.

A mounting position adjustment mechanism for a rotating door that is mounted to be rotatable around a shaft includes a base member, a support member, an adjuster, and a fixing member. The base member is configured to be fixed to a door body of the rotating door. The support member is coupled to the base member at one end side of the shaft to be movable along a door surface of the rotation door in a direction orthogonal to the shaft. The adjuster is configured to adjust a position of the support member with respect to the base member in the direction orthogonal to the shaft. The fixing member is configured to fix the support member to the base member at two or more positions on the one end side of the shaft.

A household refrigeration apparatus has a housing with a door that is pivotally mounted to the housing by a hinge. The hinge has a pivot and a separate base part, at which the pivot is rotatably supported around a rotational axis. A height adjusting device is formed at the hinge for adjusting the door in the height position in height direction relative to the housing. The pivot includes an annular coupling disk of the height adjusting device, which is coupled to a coupling receptacle formed in the base part. An individual height position of the pivot is adjusted depending on the rotational position of the coupling disk around the rotational axis relative to the coupling receptacle. The coupling disk has a coupling element with ramp-like oblique flanks on both sides, by which the coupling element axially plunges into the coupling receptacle in the direction of the rotational axis.

Described is a coupling device for a joining together adjacent dock segments of a dock installation including an elongate pin portion and at least one clamp portion, each positionable on respective dock segments. The pin portion has at least one elongate first clamp surface aligned along its length with a central longitudinal first axis, the pin portion being configured to be received in a corresponding pin-receiving region adjacent the clamp portion. The pin-receiving region is at least partially bordered by at least one second clamp surface which is aligned with a second axis. The clamp portion is configured to be actuated between an open pin-receiving configuration, at least partially opening the pin-receiving region along the second axis, and a pin-engaging configuration with the first clamp surface engaged with the second clamp surface. The second axis is configured to be substantially parallel with the first axis, and with a lateral axis of at least one of the dock segments, for securing the pin portion therewith, so that the pin portion is rotatable relative to the clamp portion about the first axis to accommodate relative movement between the adjacent dock segments.

Described are various embodiments for coupling devices for dock installations.

A hinge, in particular a multi-joint hinge, has a mounting plate fixable on a body or a door and a side part, which is held on the mounting plate and on which a hinge part is pivotably mounted, wherein the side part is displaceable on the mounting plate in a longitudinal direction via a depth adjustment unit and the side part is pivotable in relation to the mounting plate by a vertical adjustment unit.

A door hinge assembly includes a first part with a first knuckle, a second part with a second knuckle, and a pin. The pin pivotably extends through the first knuckle and fixedly extends through the second knuckle. A first adjustment member threadedly connected to the first inner threaded portion in the first knuckle to move the pin and the second part up and down. A sleeve is mounted to the second knuckle and has a slot in which the second leaf is inserted. The first part has an index area which is located corresponding to the lower end of the sleeve to indicate the axial distance that the door hinge assembly is made. A cover unit is connected to the second leaf. A second adjustment member threadedly extends through the second leaf and adjusts the door hinge assembly back and forth.

A trunk hinge includes a mounting plate configured to be attached to a vehicle, a pivot block pivotally coupled to the mounting plate, a strut pivotally coupled to the mounting plate, a hinge arm pivotally coupled to the strut, and an adjustment mechanism connecting the pivot block to the hinge arm. The adjustment mechanism can enable relative movement between a reference point of the pivot block and the hinge arm.

An adjustable hinge mechanism provides a hinging movement between first and second objects. The hinge mechanism includes a supporting component having a main body being operatively mountable onto the first object. The hinge mechanism also includes an intermediate component having a main body being operatively mountable onto the first object and being moveable with respect to the supporting component along at least opposite first and second horizontal directions. The hinge mechanism also includes a swivelling component being operatively mountable onto both the intermediate component and the second object, and being operatively moveable with respect to the supporting component along at least opposite first and second vertical directions.

Described are various embodiments for coupling devices for dock installations.
