The invention relates to a hinge assembly for a switch cabinet, comprising a housing-side hinge half and a door-side hinge half, which are connected to one another such that they swivel in relation to one another, wherein the housing-side hinge half has a mounting flange for securing to a vertical profile of a switch cabinet housing, as well as two hinge bolts extending in a vertical direction, arranged at a distance to one another in the vertical direction and facing one another with the free ends thereof, wherein the hinge bolts are accommodated in a respective bolt seat of the housing-side hinge half, wherein the hinge bolts are accommodated in their respective bolt seat such that they cannot move at least in the vertical direction, and in that they protrude from the respective bolt seat via their free ends, wherein the door-side hinge half has a bolt-receiving means with a vertical measurement that is less than or equal to the distance of the free ends of the hinge bolts.

Friction hinge (21) for the pivotable connection of two components, comprising at least one first hinge sleeve (24) which is arranged in alignment with at least one further hinge sleeve (22), a shaft (11) which runs through the hinge sleeves (22, 24), and at least one friction spring for exerting a friction torque on the movable shaft (11), wherein at least two mutually aligned friction springs (10, 10′) are connected to the first hinge sleeve (24) via radial shoulders (16, 16′) and exert a friction torque on the shaft (11) mounted in the further hinge sleeve (22).

Friction hinge (21) for the pivotable connection of two components, comprising at least one first hinge sleeve (24) which is arranged in alignment with at least one further hinge sleeve (22), a shaft (11) which runs through the hinge sleeves (22, 24), and at least one friction spring for exerting a friction torque on the movable shaft (11), wherein at least two mutually aligned friction springs (10, 10′) are connected to the first hinge sleeve (24) via radial shoulders (16, 16′) and exert a friction torque on the shaft (11) mounted in the further hinge sleeve (22).

The invention relates to a hinge assembly for a switch cabinet, comprising a housing-side hinge half and a door-side hinge half, which are connected to one another such that they swivel in relation to one another, wherein the housing-side hinge half has a mounting flange for securing to a vertical profile of a switch cabinet housing, as well as two hinge bolts extending in a vertical direction, arranged at a distance to one another in the vertical direction and facing one another with the free ends thereof, wherein the hinge bolts are accommodated in a respective bolt seat of the housing-side hinge half, wherein the hinge bolts are accommodated in their respective bolt seat such that they cannot move at least in the vertical direction, and in that they protrude from the respective bolt seat via their free ends, wherein the door-side hinge half has a bolt-receiving means with a vertical measurement that is less than or equal to the distance of the free ends of the hinge bolts.

A hinged system includes a preassembled hinge module for pivotally coupling a first component to a second component. The preassembled hinge module includes a shaft, a torque element frictionally engaging the shaft, and a housing. The housing includes a cover, a side wall, and a rear wall that define an interior space enclosed within the housing. The interior space receives the torque element inside the housing. The cover defines a first aperture, and the rear wall defines a second aperture, the first aperture and the second aperture aligned with a pivot axis of the shaft. The shaft extends through at least the first aperture, the interior space, and the second aperture. The shaft is separate from, and configured to be mounted to, the first component. The housing is separate from, and configured to be mounted to, the second component.

A partition for an animal includes a wire panel having an edge rod, a dual axes swivel connector and a wire member is disclosed. The dual axes swivel connector is pivotally connected to the edge rod of the wire panel. The wire member is mountable to a first structure. The second groove of the dual axes swivel connected is receive the wire member for forming a hinge so that the wire panel may partition a first area from a second area.

The invention relates to a hinge comprising a first part (11) that can be pivoted relative to a second part (12) about a pivot axis (a), wherein the first part (11) comprises at least one bore (13) and the second part (12) at least one recess (15a, 15b), wherein, in a final assembly position, at least pin one (17a, 17b) that is coaxial to the pivot axis (a), has a first longitudinal portion in the bore (13) and with a second longitudinal portion in the recess (15a, 15b), and the pin (17a, 17b) can be moved between a pre-assembly position, in which the pin (17a, 17b) is in the bore (13) or in the recess (15a, 15b) with a larger overlap with respect to the final assembly position, and the final assembly position. The special feature is that at least one holding element (18) can extend through a passage (31) in a seat (28) in such a way that the pin (17a, 17b) can be moved by the holding element (18) from the pre-assembly position into the final assembly position and that, in the final assembly position, the holding element (18) is positioned in such a way that it prevents a return movement of the pin (17a, 17b) from the final assembly position into the pre-assembly position.
