Abstract
Abstract In this control box, a first switching device (R-1) is actuated when the operator acts on a selector (1) whereby he can choose, on one hand, the direction of the driving of the motor (9) and, on the other hand, by means of a brief or prolonged action, the driving speed of this motor. If the action is prolonged, the switching device (R-1) is inhibited by a second switching device (R-2) controlled by a timing circuit (27) which was initiated at the start of the action. This second switching device then supplies power to the motor (9) through a series resistor (18) so long as the selector (1) is actuated. Application in an electric window raiser of an automobile vehicle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
151 words
A control box for a motor driving a slidable panel of a vehicle, such as a window glass or the like, said motor having terminals, comprising: a supply circuit for the motor, a selector associated with the motor for controlling the supply of power to the motor from said supply circuit for operating the motor selectively in a direction for opening the panel and in a direction for closing the panel, the selector having two sections each of which pertains to one of said directions, means for selecting two speeds of the motor as a function of an initial duration of actuation of the selector which is greater or less than a first predetermined period, said means for selecting the two speeds of the motor further comprising means which, when low speed operation is selected, supplies the motor at high speed during a second predetermined period for starting up the motor.
Claim 2
Dependent Claim
151 words
A control box for a motor driving a slidable panel of a vehicle, such as a window glass or the like, said motor having terminals, comprising: a supply circuit for the motor, a selector associated with the motor for controlling the supply of power to the motor from said supply circuit for operating the motor selectively in a direction for opening the panel and in a direction for closing the panel, the selector having two sections each of which pertains to one of said directions, means for selecting two speeds of the motor as a function of an initial duration of actuation of the selector which is greater or less than a first predetermined period, said means for selecting the two speeds of the motor further comprising means which, when low speed operation is selected, supplies the motor at high speed during a second predetermined period for starting up the motor.
Claim 3
Dependent Claim
33 words
A control box according to claim 1, comprising a timing circuit for ensuring the first predetermined period, said timing circuit being connected in such manner as to determine also the second predetermined period.
Claim 4
Dependent Claim
88 words
A control box according to claim 2, comprising a first switching device for closing the supply circuit of the motor when said selector is actuated, a second switching device capable of cutting off the supply of the first switching device and connected to said timing circuit so as to be actuated after the elapse of the duration of the timing of the timing circuit and also capable of allowing the supply of the motor through a series resistor so long as said selector is actuated beyond said duration.
Claim 5
Dependent Claim
102 words
A control box according to claim 3, comprising switching means for determining the direction of rotation of the motor for driving the slidable panel in either direction of movement of the panel, the switching means being at rest for one of said directions and actuated for the other of said directions under the control of said selector, and the first switching device comprising a relay whose coil is connected in series with a switch which is at rest of a second relay, said switch ensuring in its working position the closure of the supply circuit of said motor through the series resistor.
Claim 6
Dependent Claim
119 words
A control box according to claim 3, wherein said first switching device comprises two relays respectively pertaining to each direction of movement of said slidable panel and provided with a reversing switch which inserts, at rest, the series resistor in the supply circuit of the motor and which, in the working position thereof, only inserts said resistor in the circuit of the motor in respect of a single direction of rotation of the motor, said relays comprising coils connected in collector-emitter circuits of associated transistors, said transistors having bases which are connected to said timing circuit, and said selector being directly inserted in the supply circuit of the motor passing through said reversing switches in the position of rest.
Claim 7
Dependent Claim
40 words
A control box according to claim 1, further comprising a current intensity detector of the magnetic type comprising switching means capable of reversing the supply of the motor when the intensity of the current passing therethrough exceeds a predetermined value.
Claim 8
Dependent Claim
68 words
A control box according to claims 4, further comprising a current intensity detector of the magnetic type comprising switching means capable of reversing the supply of the motor when the intensity of the current passing therethrough exceeds a predetermined value, the switching means of the intensity detector being inserted in a circuit controlling said switching means for ensuring the reversal of the direction of rotation of the motor.
Claim 9
Dependent Claim
106 words
A control box according to claim 5, further comprising a current intensity detector of the magnetic type comprising switching means capable of reversing the supply of the motor when the intensity of the current passing therethrough exceeds a predetermined value, said switching means being connected to a first input of an AND gate which has a second input which is connected in the circuit of the motor ensuring one of the directions of the drive of the motor, said AND gate having an output which is connected in such manner as to close the circuit of the motor for driving the motor in the opposite direction.
Claim 10
Dependent Claim
29 words
A control box accordng to any one of the claims 1 to 8, comprising means for shorting the terminals of the motor as soon as the supply thereto ceases.
Claim 11
Dependent Claim
60 words
A control box according to claim 9, wherein said shorting means comprise a transistor responsive to a reversal of the polarity at the terminals of the motor after the supply of the motor is cut off, said transistor being capable of shorting said terminals and producing a sudden stoppage of the motor immediately after said cutting off of the supply.
Claim 12
Dependent Claim
35 words
A control box according to claim 10, comprising means for actuating the motor in a predetermined direction through switching means other than said detector for the purpose of simultaneously closing a plurality of slidable panels.
