A supporting member includes: a rotatable spindle supported in a first housing; a cylindrical first guide fixed in a second housing, and guiding a relative movement of the spindle in an axial direction; a second guide fixed in the first housing, having an inner diameter larger than a first guide's outer diameter, and relatively movable in the direction to the first guide; and a nut being a stepped shaft-like member including an insertion portion inserted into the first guide, a protruding portion protruded from the first guide, and a narrow portion provided therebetween. The first guide includes a caulking portion to the nut at an opening end. The caulking portion includes a portion extending to intersect in the direction along a step between the insertion portion and the narrow portion, and another portion parallel to the direction along an outer circumferential surface of the narrow portion.

The clamping assembly for a glass door includes an outer clamping body, an inner clamping body, an automatic homing mechanism and a positioning unit. An upper jaw for clamping the glass door is provided on the top of the outer clamping body, and a first side wall and a second side wall are recessedly formed at the bottom of the outer clamping body. A first lower jaw is formed between the first side wall and the second side wall. The inner clamping body is disposed in the first lower jaw. A second lower jaw is formed at the bottom of the inner clamping body. The automatic homing mechanism is disposed in the second lower jaw. The positioning unit penetrates the first side wall to abut against the first recess on the inner clamping body.

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.

Hinge for the support and the maneuvering of doors, made up of two wing elements and provided with means for attachment to a frame part and respectively to a door portion, as well as mutually reinforcing means in a pivoting zone, the means being constituted by appendices internally hollow in the form of a cylindrical body projecting from the wing elements, characterized in that at least one of the appendices of the wings provides on the inner surface axial grooves suitable for housing a push-engagement element housed inside a pivot pin of the wing elements and protruding from it.

Self-closing pivot hinges and devices such as doors for closing off an opening between two rooms or in a building fa?ade using such hinges include a spring that extends into a hinge housing along the longitudinal direction of the hinge housing, which lends a self-closing function, and a cam element and a ball that is pressed against the cam element by the spring. The cam element is shaped so that it creates support positions in which the ball rests.
