As shown in Figure 1, dull and stereotyped puller 10 comprises driver 1, pulling cable 2, retaining washer 3 and shutdown switch 4.Another kind of flat panel controller 10 shown in Fig. 1 a, its shutdown switch 4a is installed in rightabout.Fig. 2 and 3 at length shows the structure of driver 1, and it comprises reduction gear box 11 and motor 12, guiding pulley 13, coiling drum 14, control circuit 15 and shell 16.Motor 12 has an output shaft 121.On coiling drum 14 central cross, axle 141 is housed.This 141 can be fixed on the relative shell wall of shell 16 or be installed on the bearing of shell wall (nothing is drawn).The former allows to wind the line drum 14 around axle 141 rotations.And the latter needs both to be joined together and is fixed on the bearing to rotate.Motor 12 will and drive by control circuit 15 controls.Control circuit 15 might not be installed in the shell 16.It also can be installed in the another one housing and by suitable electric wire and be connected with the electric device that motor 12 and other are installed in shell 16.

As Fig. 1,1a, shown in 2 and 3, shell 16 is flat rectangular boxes, has L shaped notch 161 at an end of shell 16.The wherein a part of narrower one side that is bored in this flat casing 16 of notch 161, and almost across whole width.And its another part extends to the long sub-fraction on one side of shell 16.Shutdown switch 4 is installed near notch 161 inboards, and shutdown switch 4 has one to touch spiral arm 41, touches spiral arm 41 and has development length and the L shaped curve shape the same with notch 161.Have a less L shaped notch 411 along touching spiral arm 41.Because notch 161 is opened to both direction, so notch 411 also has two opening directions, and one is out at narrower one side of shell 16 notch 411 ', and another is out the long notch 411 on one side at shell 16 ".Pulling cable 2 wears out by notch 411 in the shell 16 of driver 1.Notch 411 " rightmost should surpass the vertical center line certain-length of guiding pulley 13.This two notches 411 ' and 411 " have guaranteed that towards running mouthful length jointly pulling cable 2 can be multi-direction and drawn in or pull out by twining guiding pulley 13 with the angles near 180 degree.Because such characteristics make this dull and stereotyped puller 10 have multiple flexible purposes and function.This will discuss in following paragraph.

Shell 16 has three installing holes 162 so that dull and stereotyped puller 10 is installed and is adapted to different purposes uses.Shutdown switch 4 and notch 161 can be arranged on the top of shell 16 center lines or its below.If shutdown switch 4 and notch 161 are the tops that are in it, installing hole 162 will be provided with in its lower section.This design with shutdown switch 4 (being notch 161 and notch 411) and installing hole 162 relative positions, will make at an easy rate dull and stereotyped puller 10 (window) that be implemented in the different purposes that below will discuss install and the requirement of operation, installed or with fashionable dress no matter be.But in any case, other are different from installing hole 162 and install and finished after designer that the method for dull and stereotyped puller 10 also can be easy to be known this type of technology considers these different purposes.

Pulling cable 2 is a kind of soft ropes, can use metal, and plastics or other material are made.The different-diameter of coiling drum 14 will provide different pulling cable 2 total lengths with the number of turns that pulling cable 2 centers on its winding.The pulling cable 2 of the different length that goes out from coiling drum 14 in-draws also will provide different maximum dull and stereotyped operating distances, can flexible operating flat plates with different sizes (as window) purpose to reach.This will go through in the paragraph afterwards.At pulling cable 2 a terminal cylindrical card cap 2a and the retaining washers 3 installed, the former diameter is bigger than the A/F of diameter that spurs cable 2 and notch 411.Retaining washer 3 will be fixed on the flat board with screw, as window or door etc., so that driver 1 and they couple together and transmit driving power.The lock ring that the also available a kind of arbitrarily button of retaining washer 3 breaks off relations replaces, it is used in combination with a annulus on being installed in driven flat board, just can make the user make pulling cable 2 and dull and stereotyped the disengaging at an easy rate, thereby make the flat board as window or door not use the dull and stereotyped puller 10 also can be easily with its dismounting.

Fig. 2-8 describes the structure of shutdown switch 4 in detail.Can find out that by these figure shutdown switch 4 also comprises spring 42, axle 43, limit switch 44 and support 45.Fig. 6 is clear have been described support 45 and bends the part 452 that downwards by a C shape support member 451 and two and form.By two holes 453 of bending downwards on the part 452 that, support 45 usefulness rivet rivetings or screw are fixed on the wall on shell 16 both sides.Between the upper and lower of C shape support member 451, a pulley spindle 131 that makes with the screwed bolt in bottom is housed, pulley 13 is inserted in and (Fig. 6 does not have and draws around its rotation, referring to Fig. 2 and 3), and a spacer 132 by placing pulley spindle 131 bottoms 131 ' produces it and supports positioning action.The edge of pulley 13 passes notch 41 and stretches out the certain distance of shell 16, therefore goes up and is drawn in when pulling out when pulling cable 2 twines it, and it will support and guide the motion that spurs cable 2 with the wide-angles near 180 degree.Pulley spindle 131 bottoms 131 ' down and at last are locked by a cap nut 133 by a hole extension on the bottom of C shape support member 451.The diameter of spacer 132 is less than the diameter of pulley 13, thereby to shake-up spiral arm 41 1 activity spaces inside and that outwards move, the while, it was also with less pivoting friction support pulley 13.A through hole 455 is arranged so that allow pulling cable 2 to pass through at the middle part of C shape support member 451.At the upper space place of C shape support member 451, a limit switch 44 is installed by hole 454 usefulness screws 442.

From Fig. 2,6 and 7 can clearlyer see, another one axle 43 also is loaded between the upper and lower of C shape support member 451, but its top is extended the outside on the top of C shape support member 451, so that mounting spring 42.Shake-up spiral arm 41 prolongs vertical direction a slotted hole, and this borehole jack is gone in the axle 43 and centered on its rotation.Spring 42 is inserted in axle 43 outstanding tops, and spring 42 extended ends are fixed on axle 43 tops, as shown in Figure 7.The other end of spring 42 is ridden over the longwell inboard of shake-up spiral arm 41 so that it is pushed to the outside simultaneously.The other end that touches spiral arm 41 is prolonging the extension and the last inboard of inserting shell 16 of notch 161, thereby makes spring 42 can not release shell 16 with touching spiral arm 41.The medial roof of touching spiral arm 41 leans against on the contact arm 441 of limit switch 44.Therefore, when touching spiral arm 41 when axle 43 is inwardly advanced, it will promote contact arm 441 to the right, thereby trigger limit switch 44.Because the slotted hole structure that shutdown switch 4 is above-mentioned, cylindrical card cap 2a also can promote to trigger and touch spiral arm 41 and trigger limit switch 44 by when a plurality of different angles and direction are drawn in.This will make this dull and stereotyped puller 10 become possibility for being fit to the following multiple flexible purposes that will discuss again further.In addition, the elastic force of the spring 42 of selection should be greater than the mobile frictional force of pulling cable 2, but less than the driving force of motor.Therefore, the mobile frictional force of pulling cable 2 can not spur and trigger shutdown switch 4, but has only the driving force of motor to pass through cylindrical card cap 2a just stretchy and triggering shutdown switch 4.When pulling cable 2, promptly cylindrical card cap 2a is drawn out when outside, touches spiral arm 41 and crucial lever 441 and is back into the home position in order to triggering next time by spring 42.

Shown in Fig. 2 and 3, gear-box 11 is made up of series of gears.The one end combines with motor by the motor gear 111 on motor drive shaft 121, and other end one gear wheel 112 is installed on the axle 141 of coiling drum 14.Can there be other several groups of gears to twist together mutually in the centre of these two gears.The quantity of gear train is by slowing down and moment requirement decision.This designer who is easy to be known this type of technology considers that these factors are selected.Gear 111 on the motor drive shaft 121 is coupled with gear 113 again.The gear wheel 112 of afterbody in fact be connected together with the drum 14 that winds the line and round same coiling drum 14 the axle 141 the rotation.Both can become one or link together with suitable connected mode with mold.As being example with Fig. 2 and 3, gear-box 11 has three grades, and when motor 12 during with counter rotation, coiling drum 14 will prolong the clockwise direction rotation by the power transmission of gear, so that draw in pulling cable 2 and then trigger shutdown switch 4.

Figure 4 and 5 have been described another kind of gear-box 11 ', and it adopts a bevel gear as motor gear 111 '.What motor gear 111 ' was mutually stranded therewith is a umbrella shape gear wheel 112 ".It is to carry out with the angle of 90 degree that the power of two bevel gears transmits.Therefore, the rotation direction of motor 12 ' is vertical with gear-box 11 ' rotation direction.Also can adopt other power to transmit gear such as spiral or the imperial crown gear that angle is 90 degree, and this a pair of gear also can be arranged on other tooth level position of gear-box 11 '.But for three grades of such reduction gear boxes, when motor 12 ' rotates in a clockwise direction, coiling drum 14 ' also will prolong the clockwise direction rotation to reach above same purpose by the power transmission of gear in any case.

Because the length of general motor greater than its diameter, can reduce the width of shell 16 with bevel gear, and then reduce the overall width of driver 1.Therefore dull and stereotyped puller 10 can be installed in those windows or limited local use of door surrounding space.The advantage of this width smaller will be apparent when we discuss its different purposes.The general friction that is run into hand rotation motor axle is very little, as long as the speed reducing ratio of gear-box 11 designs below suitable value, general people can both pull out pulling cable 2 in driver 1.

Fig. 1 a has showed the design of another shutdown switch 4 towards different driver 1, thus its pulling cable 2 have different operations towards and angle.The detailed design structure will be discussed at this, but for those designers that know this type of technology at an easy rate with gear-box 11, motor 12 and coiling drum 14 are realized by it is reorientated around center line Q Rotate 180 degree.As by shutdown switch 4 positions shown in Fig. 1 a (be positioned at center line Q top), pulling cable 2 will similarly pull out twining from the top of coiling drum 14 and by with its pulley 13 in level height about the same.

Fig. 9 has showed the circuit diagram of the control circuit 15 of detailed dull and stereotyped puller 10.Circuit is that the employing d.c. motor is that example is discussed.Alternating current motor also can adopt but circuit will be different.Control circuit 15 comprises microprocessor 121, motor 12, and limit switch 44, hand switch 122 triggers sensor 123 (as rain sensor, photoelectric sensor, timer and remote controller or the like), FET 124 and resistance 125 and 126.Power supply can be 5 volts of dc sources and gives power driving circuit for control signal electricity and 12 volts of roads.The gate pole 124 of FET is connected to a wherein I/O (output) port of microprocessor 121, and its source ground.A wherein port one 2 of motor is connected to 12 volts of power supplys and another is connected to the drain electrode of FET 124.A wherein port of hand switch 122 and the normal opened contact of limit switch 44 are connected respectively to a wherein I/O (input) port of microprocessor 121.They also are connected to the 5V power supply respectively by resistor 125 and 126 simultaneously, and the whole ground connection of their other end.Trigger sensor 123 the similar mode of connection is also arranged.The different sensors that trigger have difference, perhaps need power supply to operate or are connected to positive source by resistance.When the contact arm 441 of limit switch 44 was depressed, limit switch 44 was switched to connection from cut-offfing state, and this just transmits a pulse signal to microprocessor 121.The operation principles of control circuit 15 and process will come into question as follows.

Before discussion, we suppose that pulling cable 2 has been drawn out certain length, and promptly cylindrical card cap 2a has left shutdown switch 4 one segment distances.When triggering sensor 123 is triggered, it will produce a pulse signal and give microprocessor 121.Its output that joins with FET 124 will be connected from ' cut-off switch to ' program this moment of finishing according to microprocessor 121 ', so FET 124 conductings, motor 12 starts.The polarity of motor port is to connect like this: when the direction by Fig. 9 passed to voltage, motor 12 will be by rotation (or motor 12 ' rotates in the direction of the clock) counterclockwise.It is with driving gearbox 11 (or gear-box 11 ') simultaneously.And then drive coiling drum 14 in the direction of the clock and rollback pulling cable 2, compressed into by cylindrical card cap 2a and trigger limit switch 44 and produce a pulse signal and give microprocessor 121 up to shutdown switch 4.According to program, when microprocessor 121 detects such signal, it will cut off the output that it is connected to FET 124, thereby the latter will be switched to from conducting state and cut-off, thereby cut off motor 12 and gear-box 11 and coiling drum 14.But if pulling cable 2 is not drawn out certain distance and cylindrical card cap 2a still is pressed on the shutdown switch 4, microprocessor 121 will can not detect any pulse signal from the input port that is connected to shutdown switch 4.Even when triggering sensor 123 is triggered, it also will not do any reaction according to program.Hand switch 122 is to be used for manually booting and operating to replace by triggering the automatic operation that sensor 123 triggers.Its operation principles and process with described above be the same.

Below we will with window frame be fixed on the interior wall and pull-type window of revolving of how secondary sash and Straight pull window are arranged is example, and carry out detailed discussion in conjunction with the embodiment that various operations of closing and application and employing are installed in shell guiding device outward.But the principle of this invention also is to be applicable to the operation of other dull and stereotyped as doors etc. and use.

Figure 10 has showed that a fan is equipped with the Straight pull window 20 of dull and stereotyped puller 10, and driver 1 is installed on its following underframe of window frame 201, and window frame 201 has edge protection 201 ' to skid off to prevent sash 202.Retaining washer 3 is installed on the instrument bezel of sash 202, location, its installation site should with notch 411, promptly notch 411 ' on same horizon, also remains on it on par line to guarantee pulling cable 2.Such installation will guarantee level and smooth pulling pulling cable 2, and avoid because crooked pulling cable 2 is touching on the spiral arm 41 triggering that leads to errors of the too big frictional force of generation.The aforementioned notch of mentioning 411 is on center line Q and the relative position structure of installing hole 162 under it helps to have realized such purpose.In case driver 1 is mounted (bolt or other securing member) appropriate location on the following underframe of window frame 201 by installing hole 162 apparently, notch 411 ' will be guaranteed to exceed edge protection 201 ' at an easy rate.Therefore as according to above-mentioned installation requirement install, will finally keep the pulling cable 2 or its direction of motion to remain on the same level line.In addition, the relative fixed position of driver 1 and retaining washer 3 should be carried out in the following manner: in sash 202 complete fastening positions, 3 distance should be than little to the distance of retaining washer 3 from cylindrical card cap 2a from notch 411 ' to retaining washer.This will guarantee that an operating distance that holds water is given cylindrical card cap 2a so that it is at the sash 20 smooth shutdown switch 4 that triggers of almost pent moment.Concrete dull and stereotyped puller 10 operating process will details are as follows.

Before dull and stereotyped puller 10 started, sash 202 was opened with hand push, spurred promptly that cable 2 is pulled out in it and control circuit 15 is in the preparation starting state.When dull and stereotyped puller 10 starts by triggering sensor 123 controlled circuit 15, pulling cable 2 will be pulled back to left direction, and therefore, sash 202 is pulled to fastening position.When it almost is closed, cylindrical card cap 2a will touch notch 411 ' and promote shutdown switch 4, and promptly limit switch 44, from ' cut-off ' to ' close ', thereby stop the running of motor 12 or 12 '.Last sash 202 stops and closing.

Therefore locate before the window within the walls at some dwelling houses, safe window bar or safety grid are installed, the slit between itself and window is very little.The narrow width design of driver 1 will make installation under such condition and operation become may with easily.

Figure 11 has showed the Straight pull window 21 that dull and stereotyped puller 10 and are installed in the outer guiding device of shell has been installed.It has the sash 213 ' and 213 of two same width ".Its driver 1 is installed on the left frame of window frame 211, its notch 411 " towards outwards and its be positioned the outside at window frame 211 edges to cooperate the use of pulley gear 212.As shown in figure 11, pulley gear 212 is installed on the center-right position of the upper ledge of window frame 211, and pulling cable 2 twined pulley gear 212 and pull back and be fixed on the instrument bezel on the left side of sash 213 ' by retaining washer 3 at last.Pulley gear 212 devices have a semicircular guard shield 212a to go out its pulley 212b to prevent 2 landings of pulls wire cable.Guard shield 212a and pulley spindle 2/2c are fixed together or it are injection molded into one and be fixed on the upper ledge of window frame 211 with screw 214 then.In this usage, cylindrical card cap 2a is installed in the distance and sash 213 of the position of pulling on the cable 2 from retaining washer 3 " width approximately equate or slightly grow, to guarantee that it is at sash 213 ' the pent instantaneous trigger shutdown switch 4.Describe identical among concrete installation site requirement and operating process and Figure 10.

Figure 12 has showed the Straight pull window 22 that dull and stereotyped puller 10 is installed.Driver 1 is installed on the instrument bezel on the right of the sash 221 that can be pulled, and notch 411 is " towards left.Retaining washer 3 is installed on the inner edge of window frame 222 upper ledges, and this can be seen by the Figure 12 after partly removing from window frame 222 edge protections 222 '.Certainly retaining washer 3 also can be fixed on the outside of edge protection 222 ' (drawn as dotted line).Like this, dull and stereotyped puller 10 will be installed in the center line of the glass edge that departs from sash 221 and stretch out certain distance and rubbed by window frame and arrive to avoid spurring cable 2.Because dull and stereotyped puller 10 is to be installed on the sash 221, it will move together with it.Describe identical or similar in other concrete installation site requirement and operating process and Figure 10 and 11.Clearly, pulling cable 2 is from notch 411 " pull out, and cylindrical card cap 2a heading on notch 411 " triggers, rather than 441 '.More than two Figure 11 and 12 different purposes, showed the advantage of driver 1 narrow width again.If not so, sash will be blocked by window frame before being opened fully at it.So maximum that the advantage of this narrow width can make sash beat.

The shutdown switch 71 of dull and stereotyped puller 70 also can be replaced by photoelectric sensor and be used for different purposes described above.Therefore by by advance or decontrol mode of braking that window frame triggers limit switch will become with photoelectric sensor by its transmitter the emission light beam and connect this folded light beam of survey by receiver at last by the sash frame surface reflection and come trigger control circuit to finish.It also can be replaced by position sensor, and as the magnetic position switch sensor, it has two parts, and the one, magnet, another is a switch.After considering above-mentioned different purposes, the designer who uses concrete design of this magnetic position switch sensor and structure should be known this type of technology at an easy rate finished.The flexibility of present embodiment not only is confined to above-mentioned applicable cases.As long as the flat board that is pulled in the position that is movable to and the signal cable of above-mentioned limit switch or photoelectric sensor enough length is arranged, and the flat board that moves can be direct or indirect in a manner described their are triggered, it just can be provided with stop at any item and locate.This just mean the flat board that is pulled such as window necessarily stop be positioned at a point or, also can be other different position in the position of closing.So just make this invention that more other purposes are arranged.

Figure 19 has showed that this invention adopts an embodiment of dull and stereotyped puller 80, and it has a shutdown switch 81, and the latter is installed on the case body of its driver 82.Same, driver 82 has a notch 821 so that allow pulling cable 83 be drawn in and to pull out.Therefore it has and above-mentioned notch 721 identical functions and the profile mentioned.Shutdown switch 81 is also the same with above-mentioned shutdown switch 71 contact arm 811.In this embodiment, shown in Figure 20 and 21, shutdown switch 81 is by coupling together in a rotatable device 84 and driver 82.So just make shutdown switch 81 can be positioned on different positions to be fit to the requirement of different trigger angle.

Shown in Figure 20 and 21, rotatable device 84 is installed within the driver 82 and is positioned at below the shutdown switch 81.It comprises a mounting bracket 841, axle 842, male positioning disk 843 and female positioning disk 844, spring 845 and spring supporting disk 846.Axle 842 and male positioning disk 843 can be made of one with injection moulding.Axle 842 extends up through a hole (nothing is drawn) on driver 82 tops, and mounting bracket 841 couples together with a screw and axle 842 at last.Adopt bolt also to pass through in two holes of mounting bracket 841 and shutdown switch 81, both are connected.Axle 842 also extends and passes the centre bore of female positioning disk 844 downwards.In the bottom of axle 842 is to be connected by other fixed form of screw with spring supporting disk 846.Spring 845 is twining axle 842 and is being positioned between spring supporting disk 846 and the female positioning disk 844.Figure 21 has also further showed a pulley 822 and its mounting bracket 823, and its function and design are identical or similar with aforementioned dull and stereotyped puller 10.Hole 824 by dress driver 82 also is to be positioned at below pulley 822 and the notch 821, so that reach same with respect to the best orientation between the instrument bezel of window frame and sash.Certain driver 82 can exceed the window frame top than in the past more.At male positioning disk 843 a whole circle small column is arranged.And have one to put in order the hole of enclosing the same radius equal number on the female positioning disk 844 with these small columns.All holes and small column be aligned to identical spacing with on identical circle footpath in case small column by swimmingly and allow two positioning disks with different rotary angle patchhole in.These Kongzuis fortunately its hole circle limit bevel(l)ing so that allow small column easily be guided hand-hole.In addition, even more ideal is that the head of small column is made hemispherical and made its easier entering in the hole.For adjust shutdown switch 81 towards angle, at first with it, be that male positioning disk 843 pulls to, then it rotated to desired angle, at last it is put down that male positioning disk 843 and female positioning disk 844 are closed at the location, position of immediate hole and small column edge.

Figure 22 has showed the window 28 with two fan sash 281 that dull and stereotyped puller 80 is installed.Its driver 82 is installed on its following underframe of window frame 282.And pulling one end of cable 83 and brake 283 1 are reinstated on the lower frame that screw is fixed on sash 281.The size of brake 283 is big is enough to touch contact arm 811 during to left pulling sash 281 at pulling cable 83.Dull and stereotyped puller 80 of installing and locating and brake 283 (also promptly spurring cable 83) need carry out in the following manner: when sash 281 near the moment that stops, brake 283 will touch and trigger shutdown switch 81.By suitably adjusting the orientation angle of brake 283, dull and stereotyped puller 80 can be used for as at Figure 10,12,14,15 with the different purposes shown in 16.As shown in figure 13 revolve pull-type window, touch shutdown switch 81 because of the lower frame of sash 232 ' can be used as, thereby just needn't use brake 283.But,, just be not suitable for using dull and stereotyped puller 80 because of shutdown switch 81 and sash 213 ' have a segment distance in purposes shown in Figure 11.

By means of rotatable device 84, photoelectric sensor also can replace shutdown switch 81 and operate above-mentioned various uses.At this moment the lower frame of brake 283 or sash 281 (shown in Figure 13 revolve pull-type window) will be used for reflecting the light beam that produces from the transmitter of photoelectric sensor and send control circuit at last to receiver.It also can be replaced by position sensor, and as the magnetic position switch sensor, it has two branches, and the one, magnet, another is a switch.After considering above-mentioned different purposes, the designer that the concrete design of using this magnetic position switch sensor and structure should be known this type of technology at an easy rate finished.Be installed in the position of drawing as Figure 19 dotted line as shutdown switch 81 is changed into, at this moment dull and stereotyped puller 80 also can be used at Figure 10 14,15 and 16 purposes under the situation that needn't use brake 283 as dull and stereotyped puller 70.But its shutdown switch 81 must be adjusted in the face of the front of sash and so dull and stereotyped puller also need carry out suitable location, promptly is installed on the A line, to guarantee the allowing window frame of sash trigger shutdown switch 81.Contact arm 811 also should stretch out enough length so that sash touches it or decontrols it in addition.As adopt photoelectric sensor, equally also will carry out same adjustment.

Figure 23 has showed dull and stereotyped puller 90 with two gear-boxes 91 and 91 ' and motor 92 and 92 ' and the structure of shutdown switch 93 and 93 ', in two groups one on the right of shell 94 and another on the left side.A shared control circuit 95 is installed in the centre position.Dull and stereotyped puller 90 with this structure is very suitable for the pull-type window 29 that revolves with two fan sash 291 and 291 ' as shown in figure 24.Because its specific purpose, its shutdown switch 93 and 93 ' also is that it is that the notch (do not have among the figure and illustrate) of pulling cable 96 and 96 ' turnover only needs facing one direction, promptly towards the direction of sash 291 and 291 '.Shutdown switch 93 and 93 ' is by touching spiral arm 931 and 931 ' and formation such as limit switch 932 and 932 ' and have the similar 26S Proteasome Structure and Function of above-mentioned dull and stereotyped puller 10.The pulling cable 96 and 96 ' of same type is wrapped in the coiling drum 97 and 97 ' and pull out and walk around pulley 98 and 98 ' of same type respectively, is connected respectively at last on the lower frame of sash 291 and 291 '.Because the dual-element project organization, any sash 291 and 291 ' can be pushed away respectively with hand open or one be opened and another is still closed.No matter where sash 291 and 291 ' is reached respectively, behind a triggering sensor-triggered control circuit 95, they all will be pulled to the position of closing.In the moment that (latter do not have at Figure 24 illustrate) that be positioned on the cylindrical card cap 961 and 96 ' of pulls wire cable 96 triggered shutdown switch 93 and 93 ', they will stop at the position of closing fully separately.In this embodiment, control circuit 95 will increase by two input I/O, give the limit switch that increases another hand switch to increase for one.It also will increase an output I/O and give the FET that increases to drive the motor that increases.The design of the program of the microprocessor of embodiment for this reason, the designer that also can be easy to be known this type of technology is finished.

Figure 25 and 26 has showed another embodiment.Its dull and stereotyped puller 100 adopt coiling drums 101 replace pulleys guide pulling cable 102 towards a plurality of direction wide-angles draw in and pull out.As shown in figure 25, the vertical edges of minor face (side) notch 103 is positioned at the left side certain distance on the surface, the left side of coiling drum 101.The vertical edges of long limit (front) notch 104 is positioned at the right certain distance of axis of the axle 105 of coiling drum 101.The outstanding forward certain distance in surface of drum 101 in addition winds the line.All these have guaranteed that all pulling cable 102 has the pulling angle of 180 degree.For avoiding dust to enter the service behaviour that shell 106 the insides influence driving element, this embodiment has adopted a movably over cap 107.It respectively has two columniform pins 108 in its bottom and top on the left side.Pin 108 can be pressed into and by its hole inner bottom part hide into the automatic pop into position of spring.The hole 109 that two correspondences are respectively arranged in the upper and lower of notch 103 and notch 104 is to accept the insertion of pin 108.Cable 102 passes notch 103 if the purposes of dull and stereotyped puller 100 requires pulling, and over cap 107 just should block notch 104 after insertion.Otherwise notch 104, notch 103 will be blocked in this way.It is loose and kink together that over cap 107 also helps to prevent to spur cable 102 in addition.

This embodiment has adopted similar gear-box 110, and motor 111 and control circuit 112 are to obtain the same operation function.Though the same shutdown switch of each and shutdown switch 4 can be installed in notch 103 and 104 positions, its structure will be just unusual complexity and expensive.Therefore shutdown switch 71 and 81 or be used in next paragraph the current sensor that comes into question will be more suitable in dull and stereotyped puller 100 as shutdown switch.In addition, the different window purposes of the embodiment of guiding device will be with discussed above identical outward to utilize dull and stereotyped puller 100 and shell.

Figure 27 has showed that an employing current sensor 127 stops the embodiment of motor as shutdown switch.Two ports of current sensor 127 are connected between the source electrode 124 and ground of FET, the 3rd port of current sensor 127 be connected to limit switch 44 connect identical little-the I/O port (input) of processor 121.

Figure 28 has further described the detail circuits figure of current sensor 127.Its sensor resistance device 152 is connected between the source electrode and ground of FET 124.One port of resistor 153 is connected to the source electrode of FET 124 and the tie point between the sensor resistance device 152, and the other end is connected to the anti-phase input utmost point of comparator 157 and passes through capacitor 154 ground connection.Resistor 155 and 156 forms a voltage divider, and the positive of the comparator 157 input utmost point is connected to tie point between the two.Therefore the positive input utmost point at comparator 157 forms a reference voltage.When the electric current of motor rose to some values and its voltage that forms by resistor 152 and exceeds the summation of minimum trigger voltage of reference voltage above-mentioned and comparator 157, comparator 157 just its output changed into from ' height ' ' low '.Microprocessor 121 will receive this signal, and its control program is to make according to such requirement, and promptly when it receives this signal, it changes into its output from ' height ' ' low ' thereby cut-out FET 124.Finally, it is with the motor that shuts down.Below the working method of current sensor 127 will be discussed according to different purposes.

We can be used in the Straight pull window of describing among Figure 10 and the pull-type window that revolves described in Figure 13 is discussed different operating purposes with the dull and stereotyped puller of current sensor 127.It is identical with dull and stereotyped puller 10 that dull and stereotyped puller face shaping like this and size can be done.Unique difference is exactly dull and stereotyped puller any mechanically operated shutdown switch and the cylindrical card cap the same with cylindrical card cap 2a as shutdown switch 4 not among this embodiment.But other as the location of dull and stereotyped puller with install similar or identical.Equally, our cable 2 of supposition pulling earlier has been drawn out certain length.Be triggered when triggering sensor 123, by same program, motor 12 is with entry into service.Sash 202 is pulled to the position of closing then.Touch moment of the left frame of window frame 201 at sash 202 left side instrument bezels, because the ever-increasing resistance that leans sash 202, thereby increased load on motor 12, cause its electric current to increase at last.In case when the voltage of its generation exceeds the summation of voltage above-mentioned, comparator 157 will change into from ' height ' ' low ', so microprocessor 121 will detect this signal and cut off FET 124.Last motor 12 and sash 202 will stop.As being used for the purposes as shown in Figure 13 with the dull and stereotyped puller of current sensor 127, it will be closely similar with the situation of the above discussion.It will be with similar or the same for what Figure 13 discussed in front by dress and location.Similarly, be triggered when triggering sensor 123, by same program, motor 12 pulls to the position of cutting out with entry into service and with sash 202.Touch moment of window frame 231 at the instrument bezel of sash 232 ',, thereby increased load on motor 12, cause its electric current to increase at last similarly because the ever-increasing resistance that leans sash 232 '.In case when the voltage of its generation exceeds the summation of voltage above-mentioned, comparator 157 will change into from ' height ' ' low ', so microprocessor 121 will detect this signal and cut off FET 124.Last motor 12 and sash 232 ' will stop.As will being used for Figure 11 with the dull and stereotyped puller of current sensor 127, the purposes shown in 12,14,15 and 16, it will be similar with the situation of the above discussion or the same, will do not done further to discuss at this.Same as adopt a resistance to stop device as location resistance stopping device 245 and 246 ' (246 "), if the flat board that is pulled in the position that is movable to, the resistance stop that it just can stop between the device by resistance on any default position is located.This just mean the flat board that is pulled such as window necessarily stop be positioned at a point or in the position of closing, also can be in other different position.

Supposing all that in the above description pulling cable 2 has been drawn out the certain length of enclosure, also is sash certain distance that has been opened.If but it is to be closed, with the above-mentioned Circuit Design of mentioning, microprocessor 121 can't distinguish and judge whether the sash of window is closed or open.Therefore, when triggering that sensor 123 is triggered or hand switch 122 is pressed, it will react and start.But it will detect immediately from the overcurrent signal of current sensor 127 generations and cut off motor 12.Be triggering and the operation of avoiding the above-mentioned insignificant dull and stereotyped puller of mentioning, can adopt a position sensor to notify microprocessor 121 those fan windows to be opened and solve.Among Figure 27 with the drawn connection line of itself and control circuit of dotted line.We will be that example is discussed with magnetic position switch 128, and it also is operable that certain other types and this have the sensor of identical function.As shown in figure 29, magnetic position switch 128 has two parts, the one, magnet 128 ", another is a switch 128 '.Switch 128 ' can be the normal opened contact switch, and therefore, its formation one and hand switch 122 series connection add resistance and are connected to a same circuit of 5V power supply.One port is connected to the I/O port (input) of microprocessor 121 and another ground connection.As shown in figure 29, magnet 128 " be installed on the fan sash, and switch 128 ' can be installed on the dull and stereotyped puller 1.These two elements should be located by this way, and promptly when sash was pulled to the position of closing, the close enough that these two elements should be drawn was so that switch 128 ' is sensed magnet 128 " changes of magnetic field and impel its normal opened contact from ' cut-off ' to ' engage '.In addition, certain distance in case sash is open, magnet 128 " will leave the distance that switch 128 ' equates, so the normal opened contact of switch 128 ' will be transformed into from ' engage ' ' cut-off '.In this embodiment, microprocessor 121 will be programmed in the following manner: promptly only be transformed into from ' engage ' at normal opened contact that it detects switch 128 ' ' cut-off ' after, it just is in SBR, promptly just can react the signal of hand switch 122 or triggering sensor 123.Adopt such element and so programming, can eliminate insignificant triggering and operation.Servo and stepper motor control also may be utilized to save the flip flop equipment of limit switch and its labyrinth.But because expensive servo and stepper motor and their control circuit will make its cost of goods manufactured and exceed much than stopping sash with current sensor 127.
