Definitions
- the subject of the present invention is an automatic stop device for an electric motor after a certain number of revolutions, comprising at least one threaded bar on which a sliding nut is mounted, means for coupling to the motor driving in rotation one of these elements, bar or nut, means for immobilizing the other of said elements in rotation, and a switch actuated when the sliding nut arrives at the end of travel on the threaded part of the bar.
- Such devices are used in particular to ensure the stopping, at a predetermined position, of roller shutters, blinds and motorized doors.
- These stop devices generally work both on closing and on opening and comprise two threaded bars mounted in parallel and each provided with a sliding nut.
- the threaded bars are either fixed in rotation or driven in rotation.
- the sliding nuts have the shape of toothed pinions driven in rotation by a common splined shaft, itself driven by the motor.
- the threaded bars are driven in rotation by the motor, while the sliding nuts are held in rotation by a smooth bar on which they move, as described in patent FR 2 412 483.
- the counting capacity of the number of revolutions of such devices is determined by the number of threads on the threaded part of the bar and the precision of the stop is a function of the displacement of the sliding nut for a bar turn, that is to say the size of the thread pitch of the threaded part.
- the space available to house the stop device in an installation is often limited and the threaded bar cannot exceed a certain length and if we still want to keep sufficient counting capacity, we are often obliged to reduce the size of the step at the expense of the precision of the stop which is sometimes insufficient.
- any improvement of one of these characteristics is done to the detriment of at least one of the other characteristics.
- the object of the invention is to provide an automatic stopping device which makes it possible to improve one of the three characteristics above without reducing the quality of the other characteristics.
- the automatic stop device is characterized in that the threaded bar has, at one of its ends, a second threaded part, substantially shorter than the first part, of diameter greater than the diameter of the first threaded part and the thread of which has a pitch substantially greater than the pitch of the thread of the first threaded part, that the device comprises a second sliding nut linked to the first nut and cooperating with the second threaded part of the bar, and means for securing the two rotating nuts while allowing limited relative axial displacement of the nuts, when the second nut engages the second threaded portion of the bar, the switch being actuated, directly or indirectly, by the second nut after a certain displacement thereof on the second threaded part of the bar.
- the second nut In the counting phase, the second nut is simply driven by the first sliding nut and it is only when the first nut reaches the end of travel that the second nut, by moving over the second threaded part, comes to actuate the switch stop.
- the pitch of the second threaded part being larger than the pitch of the first part, the second nut, still immobilized in rotation by the first nut, then moves faster than the first nut.
- the counting and stopping functions are thus separated and provided respectively by the first and second threaded parts of the bar.
- the threaded bar can be fixed in rotation or rotary.
- the first and second threaded parts of the bar are separated by a section of reduced diameter whose length is such that the first nut can escape from the first threaded part after the second nut has engaged on the second threaded part and the two nuts are linked in rotation by means of flexible elements capable of moving apart and allowing their relative rotation in the event that a torque continues to be exerted on the first nut, respectively the threaded bar in the case where the bar is rotated after the second nut has come to a stop.
- the threaded bar is free axially against the action of a spring, so that when the second nut is in abutment against the switch, the bar can move, by reaction, against the action of the spring.
- Figure 1 is an axial sectional view of a stop device according to a first embodiment.
- Figures 2, 3 and 4 show three successive positions of the nuts of one of the threaded bars of this first embodiment.
- FIG. 5 is a sectional view along V-V of FIG. 2.
- Figure 6 is an axial sectional view of a stop device according to a second embodiment.
- Figure 7 is an axial sectional view of a stop device according to a third embodiment.
- FIG. 8 is a detailed view of the nuts of FIG. 7, in section along VIII-VIII of FIG. 9.
- FIG. 9 is a view of the same detail in section along IX-IX of FIG. 8.
- Figure 10 is a half view in axial section of a stop device according to a fourth embodiment, in a first position of the nuts.
- Figure 11 is a view similar to that of Figure 10 showing the nuts in a second position.
- Figure 12 is a view similar to Figure 10 showing the nuts in a third position and the threaded bar in another axial position.
- Figure 13 is a partial view, in axial section, of a stop device according to a fifth embodiment, in which the threaded bars are rotated.
- Figure 14 is a partial view in axial section of a sixth embodiment, in which the threaded bars are rotated and axially displaceable.
- Figure 15 is a partial view, in axial section, of an alternative embodiment of the sliding nuts, in a first position.
- Figure 16 shows the same variant in a second position.
- the device shown in Figure 1 comprises two parallel threaded bars 1 and 2, of opposite pitch, mounted in a tubular frame 3 around which is rotatably mounted a sleeve 4 intended to receive a winding tube (not shown) of blind or roller shutter.
- This sleeve 4 is provided with an internal toothed crown 5 meshing with a pinion 6 secured to a grooved shaft 7 extending in parallel to the threaded bars 1 and 2 and meshing with two toothed nuts of opposite pitch 8 and 9 mounted respectively on the threaded bars 1 and 2, more precisely on a first threaded part 10, respectively 11, of these threaded bars.
- the sliding nut 8 is integral in rotation with a second nut 12, the internal diameter of which is greater than the diameter of the threaded part 10 so that it can move freely on this threaded part 10.
- This nut 12 is against intended to be screwed onto a second threaded part 13 of the threaded bar 1 located after the part 10, of diameter greater than the diameter of the part 10 and not larger than the pitch of the part 10.
- the sliding nut 9 is integral in rotation with a second nut 14 identical to the nut 12 but with opposite steps and intended to be screwed onto a second threaded part 15 of the threaded bar 2, identical to the part 13 but of not opposed.
- the threaded bars 1 are terminated by a smooth part 16, respectively 17 by which they are journalled in a wall 18 of the frame.
- smooth parts 16 and 17 are further mounted sliding transmission parts 19 and 20 cooperating respectively with a switch 21 and 22.
- the other ends of the threaded bars 1 and 2 are extended so that they can be rotated for adjustment the position of the nuts 8 and 9 on their threaded bars, in a manner known per se.
- Figure 1 shows the sliding nuts 8 and 9 in two different positions, as well as the second nuts 12 and 14 in two different positions relative to the first nuts 8 and 9.
- the nuts are shown in more detail in Figures 2 to 5 which represent them in three successive positions by means which will describe the operation of the automatic stop device with regard to its new characteristics.
- the first nut 8 is provided with two sets of flexible tabs 23 to 26 and 27 to 30 extending parallel to the axis of the bar 1 around the second nut 12 by enclosing this nut.
- the ends of the legs of the first set 23 to 26 have a bent portion 31 in the direction of the bar, so as to axially retain the second nut 12 against the first nut 8 or at least near this nut 8.
- the second set of tabs 27 to 30 is provided with internal ribs 32 engaged in V-shaped grooves 33 of the nut 12. The nut 12 is thus secured in rotation with the nut 8 by the tabs 27 to 30.
- the operation of the device is as follows: during the counting period of turns, that is to say during the movement of the door or the winding, respectively the unwinding of the roller shutter, the first nut 8 moves in a known manner along the first threaded portion 10 of the threaded bar, carrying with it the second nut 12. This position is shown in FIG. 2. At a certain moment, when the first nut 8 arrives near the end of the first threaded portion 10 adjoining the second threaded portion 13, the second nut 12 engages with the thread of the second threaded portion 13.
- the nut 12 is preferably oriented angularly relative to the nut 8 so as to ensure the precision of the engagement of the thread of the nut 12 on the thread of the second threaded part 13. This position is represented in FIG. 3.
- the second embodiment represented in FIG. 6 differs from the first embodiment only in that the threaded bars 1 ′ and 2 ′ have the possibility of moving axially to actuate the switches 21 and 22.
- the bar threaded 1 ′ is pushed by a spring 34 working in compression between the wall 18 of the frame and the end of the threaded part 10.
- the second threaded part 13 of the bar is located at the end of the threaded part 10 opposite to the 'switch 21. This threaded portion 13 abuts against a transverse wall 35 of the frame.
- the bar 1 ′ is extended by a profiled part 36, for example with a hexagon, engaging by sliding in a tubular part with the same internal profile 37 which can be rotated from the outside for adjusting the the position of the nut 8, in a manner known per se.
- This tubular piece of adjustment is held in position by a spring 38.
- this second embodiment is similar to the first embodiment.
- the second nut 12 When the second nut 12 reaches the end of its travel, it abuts against a fixed stop 39 and, by reaction, it is the threaded bar 1 ′ which moves back and actuates the switch, as shown for the bar 2 ′ and the nuts 9 and 14.
- This smooth section 40 does not prevent the second nut 12 from coming into engagement with the second threaded part 13, but before it has come into abutment against the transmission part 19, the first nut 18 escapes from the threaded part 10 and turns freely around the reduced diameter section 40, however continuing to rotate the second nut 12, until the latter actuates the switch 21. If, at this instant, the first nut 12 continues to be driven in rotation, for whatever reason, the ribs 32 (FIG. 4) of the flexible tabs, here three in number, 27 to 29 ( Figures 8 and 9) escape from the V-grooves 33 under the effect of the resistive torque and the flexible tabs move apart allowing the rotation of the nut 8 relative to the nut 12.
- the nut 8 can thus continue turning without axial displacement and without risk of blockage which could damage the stop device.
- a spring 41 compressed by the nut 8, ensures the engagement of the nut on the threaded part 10. The same applies to the nut 9.
- An intermediate section of reduced diameter could also be provided on the bars 1 ′ and 2 ′ of the second embodiment shown in FIG. 6.
- Figures 10, 11 and 12 show a fourth embodiment in four successive positions.
- This fourth embodiment is derived from the third embodiment shown in Figure 7. It differs from the third embodiment in that the threaded bar 1 ⁇ is axially movable, as in the second form of execution shown in Figure 6. There are therefore certain elements identical to those of Figure 6 which are designated by the same references.
- This fourth embodiment however differs from the second embodiment in that it is the second nut 12 which actuates the switch 21, by means of a transmission part 19, and not the threaded bar, by reaction. Note that for the same dimensions of the nuts 8 and 12, the length of the reduced diameter section 40 ′ is less than the length of the sector 40 in FIG. 7, the length of the sector 40 ′ being little greater than the length of the thread of the nut 8 and approximately equal to the length of the thread of the second nut 12.
- Figure 10 shows the device when the set of two nuts 8 and 12 arrives at the end of the first threaded part 1 allocate.
- FIG. 11 represents the position of the nuts 8 and 12 at the moment when the second nut 12 has just actuated the switch 21 via the transmission part 19. It can be seen that the first nut 8 is still in engagement on the thread of the 1 ⁇ bar. If, at this instant, for any reason, the second nut 12 continues to be rotated by means of the first nut 8, the threaded bar 1 ⁇ moves back by compressing its spring 38 and the first nut 8 escapes the corresponding threaded part of the bar 1 ⁇ , as shown in FIG. 12. The nut 8 then turns freely on the section 40 ′ and its elastic tabs allow it to separate in rotation from the second nut 12.
- a return spring 41 ensures, on return, the engagement of the first nut 8 on the first threaded part of the bar.
- the invention also extends to devices in which the threaded bars are driven in rotation and the nuts are immobilized in rotation.
- Figures 13 and 14 partially show such embodiments.
- the nut 9 is immobilized by a fluted shaft 42 normally fixed in rotation, but which can be driven manually in rotation for adjusting the position of the nut 9.
- the other main nut 8 meshes with a splined shaft similar to the shaft 42.
- this embodiment is identical to the first embodiment.
- the threaded bars 1 ′ and 2 ′ are also rotated and axially movable, while the toothed rings of the nuts 8 and 9 are each engaged with a fluted shaft 42 normally immobilized in rotation.
- this embodiment is similar to the embodiment shown in Figure 6, that is to say that the switches 21 and 22 are actuated by the axial displacement of the threaded bars 1 ′ and 2 ′ by compressing the return springs 34.
- Securing the rotating nuts by means of flexible lugs could be achieved with different profiles.
- the nut 12 could have a polygonal outline and the legs of the first nut would simply come to bear on the faces of the second nut.
- the same tabs could provide axial retention and securing in rotation.
- the coupling of the first and second sliding nuts could be carried out in many other ways.
- An alternative embodiment is shown, by way of example, in FIGS. 15 and 16.
- the second nut 120 is provided with two rods 121 and 122 parallel to the bar threaded 1 and passing through the first nut 80.
- a spring 43, respectively 44 working in compression between the first nut 80 and a circlip 45, respectively 46, fixed to the end of each of the rods 121 and 122.
- the second nut 120 is thus secured in rotation with the nut 80, but can move axially relative to the latter, as shown in FIG. 16, by compressing the springs 43 and 44.
