The partial sectional view of an embodiment of the locker that Fig. 3 comprises for embodiment shown in Figure 2;

Fig. 4 a-4c is Fig. 3 along the schematic diagram of motor shown in the A-A line when the different rotary position.

The specific embodiment

Venetian shutter shown in Figure 1 with lower end cross bar 1 and two ropes 7,8.One end of each ropes links to each other with the downside of lower end cross bar 1, and the relative other end links to each other with the upside of lower end cross bar 1.

Lower end cross bar 1 can be directed in a unshowned track, and this track can be to install along window frame sides, as the window frame in the skylight of venetian shutter is installed.

Should be noted in the discussion above that in the annexation of describing in detail hereinafter, suppose that shutter is mounted on the vertical window.

And, should be noted in the discussion above that pitch system and ropes system must explain that with the wide meaning of most probable each in them includes any element like this, this any element is in a side or the opposite side of the air gap that is used to the motor operated separately.

Be directed down to first element is in the bottom of main window frame with change direction from the ropes 7 of the downside of lower end cross bar 1.7 of ropes from here along window frame upwards and be wound on the drive pulley 13.In theory, ropes 7,8 is only twined the drive pulley half-turn, but in the practical operation, owing to from the power of drive pulley 13 to the ropes transmission, can preferably increase a circle or more multi-turn winding.Ropes 7 is drawn towards second element downwards and guides the 3rd element into to change direction 57 to change direction 4 and level from driving 13.Ropes 7 is guided lower end cross bar 1 downwards into and is attached thereto herein.Depend on ropes 7 and be designed to guide into lower end cross bar 1, the distance of ropes horizontal extent is adjustable.

For aesthetic reasons, ropes 7 often is drawn towards in the proximity of scalariform rope 3, and this will describe in detail hereinafter.Ropes 7 can also be extended in its proximity along window frame downwards.The guiding of ropes 8 is similar to the guiding of ropes 7.Therefore, another ropes 8 is drawn towards an element to change direction 28 from the bottom side of lower end cross bar 1.Upwards guide to upper ledge from this element ropes 8, and change direction 6a by two elements, 6b flatly along described upper ledge and vertically upward with twine drive pulley 13.Ropes 8 from drive pulley 13 guided downward to element to change direction 4, level is guided an element into to change direction 58, is directed down to lower end lever 1 in this element place ropes 8 and is attached thereto.

It should be noted that ropes 7,8 is by guiding by the same element that changes direction 4.Certainly also nothing can stop two independent components of use to replace a common elements to change direction.

The above-mentioned element that is used to change direction has several different embodiments, comprises wheel, pulley or cylinder.Can learn obviously from describe in detail that these elements need not be to be easy to running, can comprise what bearing friction or reality were intercepted.

From top given information as can be known, each ropes 7,8 forms one from the upside of cross bar 1 closed-loop to the downside of cross bar 1.By means of these closed-loops, utilize in ropes 7,8 one or another direction and apply a pulling force, cross bar 1 can be raised or reduce.The pulling force that is applied on the ropes 7,8 is by reversible motor 12, dc motor for example, acquisition.The armature of described dc motor is connected on the drive pulley 13 by axle in the embodiment shown.The ring that is formed by ropes 7,8 is made the transmission of the power between ropes 7,8 and the drive pulley 13 become possibility by enough the guiding tightly to obtain enough frictions.

Also be guided out two groups of scalariform ropes 3 from lower end cross bar 1 and extend upwardly inclined element 9 to upper ledge.Each scalariform rope has two side rope 3a, 3b.At both sides rope 3a, have a series of crosspiece 3c between the 3b, slat for blinds 18 is arranged on the crosspiece 3c.For clarity sake, only show a slat for blinds 18 among Fig. 1.In theory, scalariform rope 3 is consistent with inclined element 9, all has identical benchmark model, the two is thought have only to describe its operator scheme subsequently.

Two side rope 3a of

scalariform rope

3,3b are arranged in the upper ledge and are directed and are connected on the cylinder of inclined element 9 in one of two directions around columniform oblique tube 9.According to diameter, the side rope can twine a few in relative direction before being connected to cylinder.

Inclined element 9 is fixedlyed connected with axle 16, and axle 16 is connected with motor 12 again.For more accurate, in the embodiment shown, axle 16 is to be connected to enduringly on the shell of motor 12.

Motor 12 and upper ledge are not to adopt the mode of fixedlying connected, but articulate connected modes by two axles rotations, for example, are connected to the axle of motor armature and are connected to the axle 16 of upper ledge.

At the least significant end relative with motor, axle 16 is provided with a barrier element restrictive axes 16 relative upper ledges can revolvable angle.In the embodiment of Fig. 1, barrier element comprise one with axle 16 first cogwheels 10 of fixedlying connected, described cogwheel and another cogwheel 11 meshes.Another cogwheel is arranged on the axle 19 to rotate freely the mode of not considering with 10 engagements of first cogwheel.Axle 19 relative upper ledges are fixed.

A discontinuous place 20 is shown on the tenon of another cogwheel 11.This discontinuous place can be the space width of a disappearance, or one than other tooth depths or wide tooth.

When axle 16 and first cogwheel 10, in the first direction rotation of rotation, another cogwheel 11 freely rotates along this direction.By the continuous rotation of first cogwheel 10, discontinuous place 20 rotates to first cogwheel, 10 position engaged at last and stops being further rotated of the two.From this position, axle 16 can not rotate again, but can return back to relative position.Rotation in relative direction is limited in an identical manner, because rotation can guide to the discontinuous place that runs into opposite side continuously.

In described embodiment, only used a kind of with identical discontinuous place, because the periphery of cogwheel is best suited for using.Yet, use two and also can select, can there be one this moment and the middle periphery that does not use.

Hereinafter, electric operating means just is based on that shutter position shown in Figure 1 describes, and cross bar 1 or lath are not positioned at extreme position among the figure.

Motor 12 is, as mentioned above, for example is a reversible dc motor, and motor armature rotates the direction of rotation of relative framework to be undertaken oppositely by the reversed polarity that voltage is provided.Hereinafter, adopt the word of motor direction of rotation.Can be interpreted as the direction of motion of the relative motor casing of motor armature.

If the executive component of shutter is designed in given position, be subjected to motor 12 supply current affects, this process to motor 12 supply electric currents realizes by means of electric executive component, and this electric current flows through cable 14.The electricity executive component can be a switch with three positions, for example neutral gear disconnects rubs position and two trigger positions, a trigger position is supplied the electric current of a polarity to motor 12, and another trigger position is to the electric current of motor 12 supply relative polarities.Like this, motor 12 can be in or another direction startup of rotation.

If switch is to operate by this way, i.e. the electric current of motor 12 first direction that obtains rotating, motor armature is in an assigned direction rotation with respect to motor casing.

Yet described motor 12 is not to fixedly connected with upper ledge, but with respect to the rotatable setting of upper ledge.Therefore, should provide two kinds of situations in theory, promptly motor casing is fixed and motor armature rotation, with relative situation, for example, motor casing rotation and armature is maintained fixed.

Operating means designs in this mode of resistance, as the friction and ropes system 7,8 in order to the

change direction

4,6a, 6b, 27,28,57,58 inertia force, rope 7,8 twines pulley, the frictional force of bearing 17 and the power of lower end cross bar 1 in guide rail all think to be higher than the resistance from the leaning device with scalariform rope 3 and barrier element.

Therefore the inertia force from frictional force and ropes system shown in Figure 1 all keeps ropes system position and armature regardless of the direction of rotation of motor, and motor casing rather than armature are moved.

Therefore, motor casing, axle 16, inclined element 9 and cogwheel 10 rotate together, and rotate cogwheel 11 simultaneously.

Utilize the rotation of axle 16, cylinder 9 rotates by this way, i.e. side rope 3a, one of 3b are wound on the cylinder and another is untied from cylinder.This just can obtain the banking motion of lath 18, because side rope 3a, one of 3b is raised and another is lowered, and the scalariform crosspiece at lath place just has been tilted like this.

If it is reverse to be fed to the polarity of electric current of motor, but the whole system of motor casing, axle 16, the rotation of inclined element 9 and barrier element relative direction are because resistance is the form of frictional force and inertia force and separate with direction of rotation in the embodiment of the present invention.

By console switch, just can be to the electric current of one of motor 12 supply or another polarity, lath 18 is tilted in one or another direction.

If motor current keeps the long enough time period a given polarity, the motor casing system, axle 16, inclined element 9 and barrier element intercept in above-mentioned mode up to barrier element with regard to rotating.

It should be noted that cable 14 is to design in the mode that the motor casing rotation is not stoped.In an illustrated embodiment, this design comprises that the length with cable 14 adapts to the maximum swing of motor casing, but those skilled in the art are to be understood that the design that also can use other, for example collector shoe.

When the such prevention axle 16 of barrier element, motor casing becomes fixing, and motor armature begins to rotate drive pulley 13.This just causes the pulling force to rope, and as previously mentioned, according to the direction of rotation of motor, this pulling force causes that sheer pole rises or descends.

If shutter does not need to promote fully or descend, when lower end cross bar 1 arrived the precalculated position, the electric current of motor just was interrupted.

Afterwards, by handling shutter momently in relative direction, just lath may be set in predetermined obliquity, because front frictional force and the inertia force described, above-mentioned action causes that just barrier element removes from the obstruct position.

Therefore may activate the prolongation of a direction of rotation makes motor 12 inclined slabs 18 until being intercepted, perhaps pass through prolongation actuating to another direction of rotation, until being intercepted, reduce athletic meeting and begin automatically by this moment at another direction inclined slab 18 for motor 12.

At one time, can be by to the of short duration actuating of a direction or another direction, motor 12 is for venetian shutter is set to the precalculated position, and do not influence any lifting or reduce motion.

By being cylinder 9 and/or cogwheel 10,11 select a suitable diameter, be used to set lath required time of 18 suitable angles of inclination and lifting or reduce shutter in case of necessity between between select suitable speed change value, need not carry out regularly to motor current, also need not utilize additional gear to realize transmission between motor 12 and leaning device or motor 12 and the drive pulley 13.

Even the leaning device at embodiment shown in Figure 1 has cylinder, the both sides rope 3a of

scalariform rope

3,3b twines around cylinder, also can use a pair of arm that goes out from aixs cylinder, and the scalariform rope is installed on the arm.In this case, barrier element can change the obstruct arm into.

With regard to barrier element, can be a pair of be connected with motor casing 12 and with fixing stop part 68

interactional arms

69,70, as Fig. 3 and hereinafter will describe of the present invention another

Shown in the embodiment.

Embodiment shown in Figure 2 has a slightly different ropes system, and this ropes system 7,8 does not form a closed-loop, but terminates in lower end cross bar 1 place.In order to obtain the winding regulated of ropes 7,8, the winding of these winding reel axles 71 is provided by outer rope, and wherein ropes 7,8 is stratiform when twining.

In the present embodiment, change

direction

6c, 57,58 necessary element can be no more than three, can obtain frictional force in these elements.

One of these elements, the element that just is used to change direction 6c can be replaced by the winding of ropes 6,7, represents with four-headed arrow in Fig. 2.

Because in the present embodiment, has the position of less obtained frictional force, if bearing 67 can provide a sizable part for the total frictional force of Hoisting System then be best.

Herein, must be noted that and in first embodiment of the present invention, can stop bearing 17 that most frictional force is provided without any element in theory.

Therefore will reduce rope wear and tear, also just no longer need to guarantee that rope has fixing tensile force for cylinder or rope lid.

No matter the ropes system is by the frictional force of bearing 17,67 gained, or the directed force of rope plays the part of a key player, and this can not change the necessarily higher relatively fact of frictional force.This just means the resistance that obtains from inertia force and frictional force not only than big from the inertia force of frictional resistance and pitch system, but also must be enough greatly so that ropes 7,8 remains in position, and this also is subjected to the influence of the action of gravity of lath and lower end cross bar.

Thereby for avoiding in lifter motion in order to overcome gravity and to make motor size excessive for the frictional force of offsetting gravity must apply relatively large power, influenced by the pulling force of the gravity of lath and lower end cross bar at the scalariform rope, the most handy locker locking scalariform rope

In the embodiment shown in Fig. 3-4, such locker is that to be inserted into ropes intrasystem.

Fig. 3 is a sectional view, there is shown the section of spool shaft 71 and winding scalariform rope 7,8, and for ease of the function of understanding system, the rope 7,8 of scalariform shown in the figure is downward with respect to the surface that drawing passes spool shaft.

Locker comprises a bearing support 67,67a, and motor reel 65 articulates thereon.Bearing has an internal friction, like this from the overall resistance of frictional force and inertia force then from resistance height, as hereinafter describing than pitch system.

On motor reel, form a carriage 65a, in rotary course, this carriage 65a possibility some effects helical spring 63, and another carriage 66 of some effects, this another carriage 66 is connected with hollow spool shaft 71, and this hollow spool shaft and ropes 7,8 connect.

Another carriage 66 is fixed on has two shaft portion 64a, on the axle of 64b.A shaft portion 64a is pivotally attached in the hole of motor reel 65, and another shaft portion 64b is connected on the cogwheel 72, this cogwheel 72 and suitable protuberance 73 engagements that are arranged in the spool shaft 71.

As shown in FIG., carriage, the axle of spring and locker is arranged in the hollow spool shaft 71 in the mode that locker integral body does not occupy unnecessary position.

In embodiment of the present invention shown in Figure 3, the barrier element of a pair of

arm

69,70 or a pair of screw form is set on the motor casing.Yet, it will be appreciated by those skilled in the art that also and can use other forms of barrier element, as shown in Figure 2.

The method of operable lock buckle device is described with reference to Fig. 3 and Fig. 4, and Fig. 4 shows among Fig. 3 the sectional drawing along the A-A line.

As starting point, suppose that pitch system is in the centre position, barrier element is not also in work.

From this position, to motor supply electric current, motor casing will be one or another direction rotation, and design is the same together, because the higher resistance that has surpassed the form of the inertia force when motor casing stops with frictional force and pitch system of the frictional force between bearing 67 and the motor reel 65.

Motor reel can remain on the same position, and pitch system tilts lath 18 between two extreme positions, and barrier element is started working.

After barrier element was started working, for example, screw

rod

69,70 shown in Figure 3 knocked stop part 68, and cogwheel 11 perhaps shown in Figure 2 knocks the discontinuous place of the between cog of cogwheel 12, and the resistance of retardation motion just significantly increases.This just makes that motor casing stops, and motor reel 65 overcomes the frictional force in the bearing 67, thereby realizes promoting or reducing slat for blinds 18 and lower end cross bar 1 by ropes.In theory, whether the result of this action depends on a hereinafter described locker, or changes the direct connection between motor reel 65 and the spool shaft 71 into.

With reference to Fig. 4 locker is described.In Fig. 4, bearing support 67 has a column part 67a.Column part 67a center at bearing support 67 is provided with a through hole, and motor reel 65 is articulated in wherein by frictional force.In the center of motor reel 65, a hole is set so that another axle 64 to be set.A carriage 65a is set on motor reel 65,, a carriage 66 is set on the 64b equally at axle 64a.Two

carriages

65,66 modes with the virtual cylinder center of its column part 67a that rotatablely moves at same motor reel 65 and bearing support 67 are provided with, and so that the two complements each other to form both sides and depends on that all the mode of its relative direction of rotation makes by helical spring 63.

At columnar portion 67a and two carriage 65a of bearing support 67, on 66, a helical spring setting homocentric with it.The end separately of helical spring 63 have radial in order to carriage 65a, 66 interlocks depart from part 630,631.

Position shown in Fig. 4 a, shown in arrow g, carriage 66 is subjected to the gravity effect in the clockwise direction of ropes 7,8.Therefore, carriage 66 is oppressed the helical spring radial part 631 that departs from the clockwise direction and is made the columnar portion 67a of helical spring 63 extrusion axis bearings 67.This is also effectively with axle 64a, and 64b and spool shaft 71, ropes 7,8, slat for blinds 18 and lower end cross bar 1 remain on the given position.

Because the friction between motor reel 65 and the bearing support 67, as long as pitch system does not arrive an extreme position that is intercepted by barrier element, pitch system is intercepted by baffling device herein, and the arbitrary position between Fig. 4 a-4c is all fixed.Start working in an extreme position of system when barrier element, the rotation of motor casing then has been blocked, and the substitute is motor reel 65 and hold element 65a to begin rotation.

If motor reel 65 turns clockwise, hold element 65a and move to position shown in Fig. 4 b from position shown in Fig. 4 a.By continuous rotation, carriage 65a compressing the radial of helical spring 63 departed from part 630, thereby causes that carriage unclamps with respect to the columnar portion 67a of bearing support 67.Helical spring 63 columnar portion 67a with respect to bearing 67 under motor torque that transmits by carriage 65a and the gravity effect that transmits by carriage 66 begins rotation afterwards.Three all parts, as two carriage 65a, 66 and spring 63 rotate together, simultaneously the lath 18 and the lower end cross bar 1 of shutter are lowered.

This motion can be stopped at any time, if motor direction of rotation 12 subsequently by reverse because affact two carriage 65a respectively, the gravity on 66 and the influence of frictional force just can reach the position shown in 4b down, lath is tilted.

When if lath 18 is tilted to relative obstruct position fully, motor reel can overcome the frictional force in the bearing support 67 again, and motor reel can move on to position shown in Fig. 4 c through position shown in Fig. 4 a from position shown in Fig. 4 b.

Herein, carriage 65a presses nearly helical spring second radioactivity to depart from part 631, will depart from part 630 identical modes and unclamps helical spring 63 to utilize first in an opposite direction like this.

Carriage 65a overcomes action of gravity and promotes slat for blinds 18 and lower end cross bar 1 by departing from part 631 extruding carriages 66 like this.

In three all embodiments, intercepted at motor casing before the extreme position of lath inclination, motor reel is fixed, and motor casing is fixed when motor reel rotates afterwards.

This area the skill personage all can understand, and all can make leaning device be connected with motor armature and hoisting mechanism is connected with motor casing under the thought of the present invention not deviating from.
