An actuator is provided and includes first and second shafts, a friction plate affixed to the second shaft, a one-way clutch that includes an inner diameter portion affixed to the first shaft, an outer diameter portion and a one-way clutch portion interposed between the inner and output diameter portions and a bearing. The bearing is disposed such that a compressive load path is formed from the first shaft, through the bearing and the outer diameter portion and to the friction plate and the second shaft. The one-way clutch portion is configured for free-wheeling during forward rotation of the first shaft that permits forward rotation transmission to the second shaft and for jamming during reverse rotation of the first shaft to create a drag event on the friction plate that inhibits reverse rotation transmission to the second shaft.

A rod bearing is mounted to a roller sliding along a rail to drive a sliding door of a vehicle body. The rod bearing includes an outer side portion formed in a ring shape and made of the same metallic material as the rail and an inner side portion made of a plastic material. The rod bearing has a hybrid type composite structure in which a material of the outer side portion and a material of the inner side portion are different from each other.

The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6).

A hinge for coupling a closure member to a support includes a first hinge member and a second hinge member pivotably mounted on the first hinge member through the intermediary of two rolling bearings that are placed between different abutments. The hinge further includes a damping mechanism for damping a closing movement of the closure member; and an energy storing mechanism for storing energy when opening the closure member and using the energy to close the closure member. One of the rolling bearings supports the weight of a right-handed closure member while the other of the rolling bearings supports the weight of a left-handed closure member if the first hinge member is always fixed to the same element.

An inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth.

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 roller assembly for supporting a sliding security grille from an above-mounted track is disclosed. The roller assembly has a shank for securing the roller assembly to a panel of the sliding security grille and a rotatable collar that couples the shank to the wheels of the roller assembly to allow the axial rotation of the wheels about the shank. The roller assembly also includes an axle support that couples the wheels to the rotatable collar, and the axle support is sized to interfere with the lips of the track to limit the axial rotation to keep the wheels aligned in the longitudinal direction of the track.

Door hinge, configured by a base body (3) having a flat surface (4), to be joined, by means of an adhesive or screws, to the upper and lower base of the piece of furniture, and a circular cavity (8) to receive, fitted therein, the lower or upper edge end (2a) of the door, either directly through insertion of a projection (9) of the door, dimensioned for that purpose, or through a rotation cylindrical part (11). The rotation cylindrical part (11) is an independent piece or it is joined integrally to the upper or lower edges end (2a) of the door (2) or it is part of the door itself. The edge of the base body (3) of the hinge (1) is provided with a recess (13) suitable for receiving, fitted therein, a projection (14) of the door in a matching position, intended to secure closing thereof.

An automatic door operator and a drive mechanism thereof are disclosed. The drive mechanism of the automatic door includes a planetary reducer driven by an electric motor, and a drive shaft driven by a planetary reducer. The planetary reducer includes a housing and a planetary gear train mounted in the housing. The planetary gear train includes a final-stage planet carrier configured to output torque, and a center of the final-stage planet carrier is provided with a torque output hole. A first end of the drive shaft is detachably inserted in the torque output hole and is non-rotatably connected to the torque output hole, and a second end of the drive shaft extends out of the housing. The drive mechanism of the automatic door operator is advantageous to the miniaturization design of the automatic door operator.
