A key duplicating machine includes: a support structure, a front operational area which is accessible by the operator and which is removably covered and separated, at least partially, from the external environment by a covering and/or protection crankcase movable with respect to said structure of support. At least one key cutter and/or another cutting element, and at least one terminal (12) for locking a key, are housed in the front operational area, a rear containment area, covered and separated from the external environment by a casing mechanically fixed to the support structure, and a control and command unit having a mechanism for moving said crankcase for covering and/or protecting the front operational area, the crankcase being configured to be mounted on a fixed structure of the duplicating machine so as to be able to be moved with respect to the fixed structure.

A sliding door for a vehicle, which is applicable to a door portion to which a straight rail is difficult to be applied, may include a door rail mounted in a door which is configured to be closed to a vehicle body in a vertical direction of the vehicle; a vehicle body rail mounted in the vehicle body to which the door is configured to be closed in a longitudinal direction of the vehicle; and a moving arm having one end portion which is movably coupled along the door rail in the vertical direction to open or close the door in a transverse direction of the vehicle body during moving, and the other end portion which is movably coupled along the vehicle body rail in a longitudinal direction to allow the door to be slidingly moved in a longitudinal direction of the vehicle body during moving.

An automatic door opening system including a door having a top portion, a bottom portion, a hinged portion, and an opening portion. The system includes an opener connected to the door adjacent the opening portion and configured to selectively receive electrical current. The system includes a magnet disposed on the opening portion of the door such that the magnet is adjacent the opener when the door is in the closed position. The system includes a microcontroller in electric communication with the electromagnet wherein a memory contains processor-executable instructions to receive a door activation input and, in response to receiving the door activation input, activate the electromagnet to apply a magnetic force against the magnet and push the door between the closed position and the open position. The system may also include a closer configured to selectively return the door to the closed position.

An embodiment vehicle hinge driving apparatus includes an actuator, a housing connected to the actuator, an output shaft having an axis aligned with an axis of the housing, a transmission mechanism configured to transmit a torque from the actuator to the output shaft, and a brake unit configured to provide a brake torque to the output shaft.

The disclosure relates to a sliding door operator system (1) for opening and closing an opening (2), comprising: a track (3) configured to be mounted at an upper part (21) of the opening (2), one or more sliding door(s) 10 slidably connected to the track (3) and comprising a door leaf (4) configured to be moved along the track (3) between an open (o) and closed (c) position, and a drive unit (5) mounted on the door leaf (4), moveably connected to the track (3) and arranged to move the door leaf (4) between the closed position (c) and the open position (o). The disclosure further relates to a drive unit (5) for moving a sliding door leaf (4) between an open and a closed position (O, C) and a control system (11) for regulating one or more sliding door (10).

The invention concerns a drive unit for moving a door relative to a door's opening. The drive unit comprises a drive motor and a wheel transmission assembly arranged for transfer of power to a drive wheel configured for engagement with a running surface for moving the door. The wheel transmission comprises a transfer wheel driven by the drive motor. A movable wheel carrier comprises a first running wheel and a second running wheel arranged in in engagement with the transfer wheel. The movable wheel carrier is arranged for displacement between a free wheel position where the first and second running wheel are arranged disengaged from the drive wheel for no power transfer to occur from the drive motor to the drive wheel, at least one running position where either of the first and second running wheel is positioned in engagement with the drive wheel for the transfer of power from the drive motor to the drive wheel.

A door operator having an automatic roller closes and opens a door attached to a doorjamb by a door hinge. The roller is actuated by a motor and housed within a protective roller casing affixed to the bottom of a door. The door operator may be integrated with a smart home, thereby allowing a user to close and open a door by voice command. The door operator may be retrofitted to existing doors. A door may also be modified such that only a magnet holds the door closed and a closed position such that the smart home door closing apparatus may be used to open a door. The roller may translate between an extended position engaging the floor below a door and a retracted position above the floor, either inside or adjacent to the door itself.
