In the same figures designate the same reference numerals or similar Elements.

In 1 is with the reference number 1 a board shown. This board 1 is by conventional techniques (for example, nesting) with the end of an electric motor 2 firmly connected, which allows the lane of a roller shutter, at the height of one with the rotor of the electric motor 2 firmly connected Aufwickelrohrs cooperate, both in the direction of upward movement and the downward movement in rotation.

This board 1 is with a first shot 3 provided, which is intended to be a drum 4 which is substantially cylindrical and is recessed in its center to receive and rotate.

This drum 4 has on its outer peripheral wall a groove 5 in which a traction organ 6 cooperates, this pulling member on the one hand by a in the board 1 provided opening 7 and on the other hand at the height of a box passage 8th which runs in one of the box 9 the roller shutter forming walls is provided to make the tension member accessible to a user.

The drum 4 is also on its outer peripheral wall with a stop 10 for an elastic organ 11 Provided by the type coil spring, this at the level of its other free end inside a in the first recording 3 the board 1 provided opening 12 interacts.

This elastic organ 11 allows the return of the drum 4 in its initial position after a train of the user to the tension member 6 to ensure the rotation of the drum 4 has caused about 1/4 turn.

The combination of the tension member 6 and the elastic organ 11 allows the drum 4 inside the first shot 3 to give a back and forth twisting motion.

The drum 4 is also at the level of its inner peripheral wall with at least one flexible flap 13 provided, wherein the free end of this flexible flap is directed so that it is the entrainment of a ratchet wheel fourteen causes the coaxial inside the drum 4 is mounted.

This ratchet wheel fourteen has a plurality of toothed zones on its outer peripheral surface 15 which communicate with each other either zones of the drive in one direction of rotation of the drum 4 or zones of evasion in the other direction of rotation of the drum 4 form.

The drum 4 is over a connecting rod 16 with a switch device 17 connected in a second in the board 1 intended recording 18 is positioned.

The switch device 17 has a device that by a slider 19 , a piston 20 and a finger 21 is formed.

The second shot 18 has an overall rectangular cross-section and has side surfaces 22 that allow the guide of the slider 19 according to a first direction, to ensure the bottom wall 23 the second shot 18 is substantially perpendicular.

The slider 19 is also with at least one guide surface 24 provided substantially in a second, directed to the previous vertical direction and thanks to which the piston 20 according to this second direction due to complementary guide surfaces 25 can slide.

The piston 20 acts at the height of the free end of the connecting rod 16 so together, that with the drum 4 A connecting rod crank system is created to control the rotational movement of the drum 4 in a translational movement of the piston 20 and thus the entirety of the switch 17 convert.

The piston 20 is with your finger 21 over a groove 26 or the like, in which one perpendicular to the finger 21 prominent projection 27 slides.

The reciprocating translational movement of the piston 20 affects the finger 21 out, with the finger 21 a plurality of electrical contacts, which make it possible to make electrical connections to the electric motor, which is fixedly connected to a tube for winding the roller shutter track, said connections depending on the position of the finger 21 an upward movement of the track of the shutter, a downward movement of this track, their stop either in an intermediate position between a fully moved down or fully moved up position of the web or in an end position due to an upper or lower stroke end of the web with it.

An elastic organ 33 that in the second shot 18 between the slider 19 and the bottom wall 23 this recording 18 is positioned, constantly presses the electrical contacts of the finger to those of the electric motor.

In 1 It is possible to notice that the electric motor 2 further with a variety of noses 28 . 29 is provided, which project either on the front side on the engine or on the outer peripheral side. These noses 28 . 29 , whose object will be explained in the further description, take part in the shutdown of the engine.

In 1a is a detail of the execution of the tension member 6 shown. This has a safety device 30 which allows to limit the tensile forces exerted on the drum. This is made up of two annular parts that interlock. One of the rings has an opening 31 which, in the case of the occurrence of a force of too great magnitude on the tension member 6 can open. The ring with opening separates from that with the drum 4 connected part of the tension member and prevents any destruction of the control device. You can also thanks to this safety device, the length of the tension member 6 easily adapt.

The 2 . 3 . 4 illustrate the different positions that the components that the in 1 form illustrated control device, can take.

So shows 2 the position of the control device in the "upward movement" position of the web of the roller shutter. The switch is operated by the piston with a reciprocating movement from bottom to top and from top to bottom (in 2 is the piston at the top), one after the other the positions "stop" ( 3 ), "Upward movement" ( 2 ), "Halt", "downward movement" ( 4 ), Stop, upward movement, etc. happens. This work cycle is in 6 shown.

Any action of the user on the tension member 6 moves the drum 4 the ratchet wheel fourteen by a quarter turn, which via the connecting rod-crank system, a translation of the slider 19 and the finger 21 upward or downward translation.

3 shows the stop state of the engine. The finger 21 is in a central position and in a stable condition. On each side of the tab 27 arranged elastic organs 32 are only in this operating position at rest. In the other positions "upward movement" or "downward movement" remains one of the elastic organs 32 burdened, the other is relaxed.

Upon disappearance of the load of the tension member 6 brings the elastic organ 11 the drum 4 back to their initial position, the toothed zones 15 of the ratchet wheel fourteen dodge, the finger 21 remains in its position and returns to the tension member only after a finite number of times by the user 6 back to its "halt" position (cf. 6 ). It automatically returns to the "stop" position only in the event of a counteracting moment occurring, with one of the loaded organs 32 now the finger 21 returns to its stable position.

The position "stop", the in 3 is a user-wanted position "stop", which actually corresponds to an intermediate position of the roller shutter track between a fully shut down or fully raised position of this track.

4 shows the position of the piston 20 and the finger 21 in a position "downward movement" of the roller shutter track.

The position of the switch 17 that allows the "upward movement" or "downward movement" of the roller shutter track to be carried out is purely conventional and actually depends on the electrical connections that exist between those of the finger 21 worn contacts and arranged on the electric motor contacts are made. The in the 2 and 4 modes of operation could also be reversed without departing from the scope of the invention.

In 5 the position of various elements forming the device for controlling the electric motor has been set to a "stop" position due to the occurrence of an upper stroke end or a lower stroke end or an unwanted blockage of the roller shutter track in the direction of "upward movement" or "downward movement.""presented.

You notice that the engine 2 at least one protruding nose 28 . 29 includes, which allows the slider 19 inside the second shot 18 the board 1 according to the first direction to move straight and the piston 20 from the lead 27 of the finger 21 Uncouple the electrical supply of this motor by returning this finger 21 to the position "stop" to interrupt.

Namely, when the web of the shutter comes up or down, or encounters an obstacle between these two positions, the roller shutter track transmits to the winding tube a reaction force which tends to slightly rotate the rotor part with respect to the stator part of the motor. This counteracting moment causes an angular movement of the noses 28 and 29 on the front or on the circumference of the engine 2 are arranged. The noses 28 come with chamfered walls 34 on the piston 20 are provided in contact and cause its return movement according to the first direction, since that with the piston 20 firmly connected slider 19 in the second shot 18 is slidably mounted according to this direction.

The lead 27 Now step on the piston 20 provided groove 26 off and the finger 21 thanks to the elastic organs 32 return to the stable position.

A following train on the tension member 6 the system puts fingers 21 /Piston 20 of the switch 17 back again.

As in 6 shown, it is necessary on the tension member 6 to exert an effect to cause an upward or downward movement on the engine.

The circumferential nose 29 is with a knife 35 provided at the height of a stop 36 interacts with the stop 36 with the help of at least one elastic organ 40 in a third recording 37 that in the board 1 is provided, is held in position.

The zones 38 the interaction between the stop 36 and the knife 35 Incidentally, they include inclined walls 39 whose degree of inclination differs depending on the direction of rotation of the motor.

You can do this in this way thanks to these sloping walls 39 differentiate the trip threshold between the upper or lower stops as it is known that virtually no force is required in the downward movement of the roller shutter track. The stop 36 allows rotation of the motor only at a certain value of the counteracting torque. Due to the different degrees of inclination between the inclined walls 35 you can by simply turning the stop 36 Regardless of whether the electric motor is mounted on the take-up tube in the roller shutter box on the right or left, the direction of the upward movement or the downward movement.
