The power supply of the motor is ensured by the guiding rail (4) and by a power supply member which is parallel to said guiding rail, wherein said power supply member is formed by the rail (4) which is mounted on the ceiling and intended for receiving the door (1). The chain (35) is attached rigidly to one end of the rail mounted on the ceiling. At its other end (Fig. 6), the chain is clipped into said ceiling-mounted rail (4) and is provided with clamping members (41, 42, 44). The chain (35) is also part of the power supply member.</p> |
