A hinge system is described having at least one first hinge leaf with a single bore, suitable for fixing in an elongated opening or a row of openings in a thin wall, such as a door leaf or door frame of a metal cabinet or housing, wherein the first hinge leaf comes to lie against the margins of the breakthrough or the row of breakthroughs on one side of the thin and with a plate which comes to lie against the margins of the breakthrough or the breakthroughs on the other side of the thin wall, and with a screwed connection which presses together the two surfaces lying on the marginal surfaces, wherein, in the region of the breakthrough, projections extend from the hinge leaf or the plate which extend into or through the breakthroughs, wherein recesses are formed in the plate or the hinge leaf to receive the projections, wherein the projections are guided by the surfaces of the inner edges of the breakthroughs, wherein the threaded bore for the free end of screw passed through a projection provided with a bore.

A spacer assembly includes a housing that is configured to couple to a component. The housing includes a central bore. A bumper is coupled to the housing. The bumper includes a bumper support including a shaft that extends within the central bore, and a bumper head coupled to the bumper support.

A handle assembly for a door or window comprises a handle and a second element, installable on opposite sides of the door or window, and a pin element rotatable around a pin rotation axis and insertable into the handle or in the second element at variable depths. The handle assembly further comprises a friction reducing group positioned coaxially to the pin element and positionable between the handle and the door or window in the axial direction of the pin rotation axis. Clamping devices constrain the handle and/or the second element on the pin element at adjustable distances along the axial direction according to the thickness of the door or window, so that when the handle assembly is installed on the door or window, an axial clamping pressure of the handle and of the second element is maintained on the respective side of the door or window. An installation method of the handle assembly on the door or window is also provided.

A device for a power opening tailgate of a vehicle includes an attachment means mountable to a vehicle wall at a first side of the vehicle wall for supporting a working cylinder for opening the tailgate, and a component for reinforcement of the vehicle wall. The reinforcement component is mountable to the vehicle wall at a second side of the vehicle wall, which second side is opposite to the first side of the vehicle wall, and the attachment means and the reinforcement component are mechanically connectable to each other via a through hole of the vehicle wall.

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 hinge includes a fore-aft adjustment bracket, a lateral adjustment bracket, and a vertical adjustment bracket including a fore-aft adjustment opening, a lateral adjustment opening, and a vertical adjustment opening, respectively. The hinge also includes an upper housing member coupled to the fore-aft adjustment bracket, and a lower housing member coupled to the lateral adjustment bracket and the vertical adjustment bracket. The hinge further includes a hinge pin accommodated in a hinge pin opening defined by the upper and lower housing members, a pair of guide pins accommodated in a pair of arcuate channels in the lower housing, and a fore-aft adjustment eccentric fastener, a lateral adjustment eccentric fastener, and a vertical adjustment eccentric fastener configured to extend into the fore-aft adjustment opening, the lateral adjustment opening, and the vertical adjustment opening, respectively.

In at least one implementation, a nut for a hinge pin includes a head and a sidewall portion extending from the head to a free end. The sidewall portion includes at least one void that defines part of at least one sidewall section. The void extends radially through the sidewall portion and along at least part of the axial extent of the sidewall portion including the free end so that the free end of the sidewall portion is not circumferentially continuous.

A hinge system is described having at least one first hinge leaf with a single bore, suitable for fixing in an elongated opening or a row of openings in a thin wall, such as a door leaf or door frame of a metal cabinet or housing, wherein the first hinge leaf comes to lie against the margins of the breakthrough or the row of breakthroughs on one side of the thin and with a plate which comes to lie against the margins of the breakthrough or the breakthroughs on the other side of the thin wall, and with a screwed connection which presses together the two surfaces lying on the marginal surfaces, wherein, in the region of the breakthrough, projections extend from the hinge leaf or the plate which extend into or through the breakthroughs, wherein recesses are formed in the plate or the hinge leaf to receive the projections, wherein the projections are guided by the surfaces of the inner edges of the breakthroughs, wherein the threaded bore for the free end of screw passed through a projection provided with a bore.

A pulley mounting structure includes a pulley assembly and a slide rail which has a top part, a bottom part and an opening between the top part and the bottom part; the pulley assembly includes a support body and a pulley rotationally mounted to the support body, the pulley is inserted into the slide rail through the opening and in sliding fit with the bottom part of the slide rail; the support body has a limit part, and is configured to be rotatable from an initial mounting position to a working position relative to the slide rail around a central axis of the pulley, so that the limit part can at least partially enter into the slide rail in the initial mounting position and rotate to face the top part in the working position, the limit part is configured to abut against the top part in the working position.

A spacer assembly includes a housing that is configured to couple to a component. The housing includes a central bore. A bumper is coupled to the housing. The bumper includes a bumper support including a shaft that extends within the central bore, and a bumper head coupled to the bumper support.
