Abstract

Abstract A control device for a motor-driven closure panel, for instance an automobile sunroof panel whose closed position is an intermediate position between an open, retracted position and another open, pivoted position, the circuitry for the reversible motor including an impulse relay operating a control switch in one of the two motor connections, the relay coil being connected in parallel to the motor and between the control switch and the pole reversing switch, a position-responsive switch cutting off the relay circuit whenever the panel moves out of its closed position and energizing the impulse relay whenever the panel reaches the closed position.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 184 words
A control device for an electromechanically operated closure panel, for example, of the kind used in so-called power windows, power doors, and power sunroofs of automobiles and the like, comprising in combination a reversible electric motor and power source therefor; transmission means between the motor and the closure panel capable of moving the latter into and out of a closed position; a pole reversing switch arranged between the power source and the connecting leads of the motor; an relay having its winding connected in parallel with the motor between the motor connections and the reversing switch; a control switch actuated by the relay and arranged to open and close at least one of the motor leads between the parallel connections of the relay winding and the motor; a position-responsive switch arranged in one of the connections of the relay winding; means for actuating the position-responsive switch in response to the movement of the closure panel and its transmission means; the actuating means actuating the position-responsive switch and the relay to cut off the motor as soon as the closure panel reaches a predetermined position.
Claim 2
Dependent Claim 184 words
A control device for an electromechanically operated closure panel, for example, of the kind used in so-called power windows, power doors, and power sunroofs of automobiles and the like, comprising in combination a reversible electric motor and power source therefor; transmission means between the motor and the closure panel capable of moving the latter into and out of a closed position; a pole reversing switch arranged between the power source and the connecting leads of the motor; an relay having its winding connected in parallel with the motor between the motor connections and the reversing switch; a control switch actuated by the relay and arranged to open and close at least one of the motor leads between the parallel connections of the relay winding and the motor; a position-responsive switch arranged in one of the connections of the relay winding; means for actuating the position-responsive switch in response to the movement of the closure panel and its transmission means; the actuating means actuating the position-responsive switch and the relay to cut off the motor as soon as the closure panel reaches a predetermined position.
Claim 3
Dependent Claim 107 words
A control device as defined in claim 1, wherein the position-responsive switch is arranged to remain open when it is not actuated by the actuating means, the latter being so arranged in their relative motion to the switch that the switcH is closed when the closure panel is in its closed position, the arrival of the closure panel in the closed position thus causing the position-responsive switch to close, thereby actuating the relay and the control switch to cut off the power to the motor, the closed circuit of the relay winding permitting re-closing of the control switch through opening and re-closing of the pole reversing switch.
Claim 4
Dependent Claim 37 words
A control device as defined in claim 2, wherein the actuating means are so arranged that the position-responsive switch is closed in the closed position as well as in the fully open position of the closure panel.
Claim 5
Dependent Claim 82 words
A control device as defined in claim 1, wherein the position-responsive switch is arranged to remain open when not actuated, the actuating means including at least one actuating cam moving relative to the switch in synchronism with the movement of the closure panel, the cam upon reaching the switch cutting off the power to the motor by energizing the relay and opening the control switch, the cam maintaining the position-responsive switch closed until a new movement of the closure panel is initiated.
Claim 6
Dependent Claim 37 words
A control device as defined in claim 4, wherein the actuating means include an actuating cam which actuates the position-responsive switch in a position of the closure panel which is located intermediate the two extreme panel positions.
Claim 7
Dependent Claim 51 words
A control device as defined in claim 5, wherein the actuating cam has such a length that its cutting off of the motor causes the closure panel to come to a stop in approximately the same intermediate position regardless of the direction from which the panel moves into the intermediate position.
Claim 8
Dependent Claim 29 words
A control device as defined in claim 5, wherein the actuating means also include an actuating cam for at least one of the two extreme positions of panel displacement.
Claim 9
Dependent Claim 100 words
A control device as defined in claim 5, wherein the closure panel represents the roof panel of a so-called automobile sunroof; the transmission means include a bridge which is horizontally displaceable between two end positions, a push-pull cable moving the bridge in response to the rotation of the reversible motor, and linkage means between the bridge and the roof panel which cause the latter to move from an extreme upwardly pivoted position, through a horizontal closed position, into an extreme retracted open position, and vice versa; whereby the intermediate panel position represents the horizontal closed position of the sunroof panel.
