Title: Drive means for movable parts of vehicle coach work and the like
IPC: E05F15/14
Filed: 1971-11-10
Abstract: 1345197 Control of DC motors W BAIER W BAIER L SCHOBER AND E SCHLUMPRECHT 10 Nov 1971 [5 Jan 1971] 52183/71 Heading H2J [Also in Division E2] The sliding roof of a vehicle is controlled by an electric motor 6 energizable in one or other direction by operation of a reversing switch 1 connecting the motor to a D.C. supply 15, 16, the energizing circuit being completed through a switch 14 which is actuated by an impulse relay 12 when the latter is energized through a switch 13 actuated by a control member 11 movable by the motor. The circuit connections shown in the Figure correspond to the closed position of the roof, Fig. 4 (not shown), which is lowered and then opened, Fig. 3 (not shown), by operation of the switch 1 to engage contacts 2, 3, the resultant energization of the relay 12 closing the switch 14 to drive the motor 6 in the appropriate direction. The motor movement disengages the member 11 from the switch 13, Fig. 2 (not shown), whose opening does not affect the condition of members 12, 14, the motor being driven until the switch 1 is released to return to its centre (off) position or the arrival of the roof at its fully-open position actuates a slipping clutch to prevent the motor stalling before it is switched off. Operation of the switch 1 to engage contacts 4, 5 runs the motor in the reverse direction to close the roof, the attainment of the closed position causing the member 11 to close the switch 13 which energizes the relay 12 to open the switch 14. To raise the roof, Fig. 5, (not shown), the switch 1 is operated to engage contacts 4, 5 in the closed roof position shown in Fig. 1, the consequent energization of relay 12 and closure of switch 14 causing the motor to run in its closing direction, which now effects the raising action until switch 1 is released or the slipping clutch is operated. The motor rotation again moves the member 11 to allow the switch 13 to open, Fig. 2 (not shown), the subsequent reversal of the rotation by operation of switch 1 to lower the roof causing the switch 13 to be closed and members 12, 14 to de-energize the motor. If desired, means (not shown) may be provided to close the switch 13 when the roof reaches a fully-open position, e.g. either extreme position of the member 11, the switch being open as the member travels to these positions.
