It is the common unsettled U.S. Provisional Application sequence number 60/864 of " Drapery MasterCarrier with Automatic Disengager " that the application relates to and require the title of submitting on November 7th, 2006, the rights and interests of 702 date of application are for its full content of each purpose here is merged in by reference.

Invention field

The present invention relates to pull the master carrier (master carrier) of crossrange maneuvering valance system (traversing motorized draperysystem), particularly make the master carrier transmission mechanism break away from the ability of the carriage system (carrier train) of support valance or curtain fabric or material.

Background technology

The valance back-up system that allows to open and close up valance is known.Such system generally is made up of the aluminium that comprises a series of rollers or slipper bracket, steel or plastics head track (headrail).These carriages have valance fabric or the material that is connected to them by modes such as valance hook or other elements.According to the form of rivel, these tray chambers separate about three inches.According to the form of rivel system, each carriage may or also may not can be connected to each other directly equally.In the most general form, they connect indirectly by the valance fabric that hangs.Most important carriage or master carrier generally are connected to the valance fabric foremost.

Master carrier generally is connected to the transmission rope of guiding in metal or aluminium head track inside mostly, between the head track sidewall.At each end of head track, transmission rope generally is conducted through the flywheel belt pulley (free-wheel pulley) of non-transmision end and the driven pulley (drive wheel) of driving end.Its prevailing can manually operated form in, transmission rope is vertically guided downwards at driving end, downwards circlewise.By pulling to down an end of rope circlewise, valance will close up, and by drawing the other end, valance will be opened.Some valance systems do not have transmission rope, but by drawing the bar that is connected to transmission bracket to operate.Some systems are started by rope, but by steel wire or bring transmission.

The valance system can be made up of a face (panel) of only opening (unidirectional opening) to an end, and perhaps they can be made up of two faces, and these two are closed up towards the centre and bring in and open (open the centre) by each face being moved to one.Under the very long situation of window, on same head track, can hang face, to open these faces simultaneously with single drive motor more than two.

For fear of too much wearing and tearing with tear the valance fabric, do not recommend usually by drawing valance fabric or material itself to open and closing up the valance panel.Particularly in the system that rope starts, may need sizable power by drawing fabric rather than stay cord that valance is drawn back or closing up required power, thereby cause infringement fabric or system.

It is not that direct type of belt drive is exactly the indirect drive form that known motor provides the valance system of power.In direct type of belt drive, motor is directly connected to head track, and rotary power is sent to transmission rope or driving-belt by gear mechanism.The indirect drive form comprises rope drive motor (cord-drive motor), and it is installed in certain distance below the valance head track usually, and has the perpendicular rings of the transmission rope that extends below head track, and transmission rope is conducted through the pulley that is connected to motor.The rope drive motor is difficult to hide usually, often needs the adjusting of restricting is more safeguarded, and strong unlike direct drive motor usually.Usually, the rope drive motor is used to improve shipper rope transmission valance system more.

Directly transmission valance motor is equipped with usually provides pulley or the sprocket wheel of tractive force with rotation transmission rope, driving-belt or drive line.The master carrier of valance system is linked on driving-belt, transmission rope or the drive line by fixedly connected usually.

Because directly drive motor generally all is hidden in the back of valance fabric fully, therefore for the user, usually and be not easy to see that the valance system has been motorization.Ill-conceived user may attempt to begin to draw fabric to need motor to rotate the curtain that just can open or close up to open or to close up.Yet, stoped such rotation because directly be in transmission connection, so if the user has applied too much power, this just might cause damage to mechanism or fabric so.

In order to prevent this infringement that causes owing to the inadvertent manual operation of user, must there be a kind of method or mechanism to allow the simple manual movement of valance fabric, and can power transmission system not caused damage, for example, disconnect the connection between motor and transmission rope, driving-belt or the drive line by when not having electric current to be applied to motor.There are two kinds of methods to realize this purpose at present: electromagnetic axis decoupler (electro magnetic shaft disconnect) and overlapping main decoupler (overlap masterdisconnect).

The electromagnetic axis decoupler is made up of motor drive shaft, and motor drive shaft connects the power transmission shaft and the rope drive pulley of direct drive motor.By connecting power supply to motor, the magnet in the electromagnetism decoupler is energized and shaft end is moved in the coupling opening of driven pulley, thereby sets up fixedly connected between motor and drive line.The shortcoming of this system is that the most commonly, this system is operated by the drive motor that starts and stop by current sense.They need sizable torque ripple (torque surge) and therefore noisy often.

The off device of prior art exists with two kinds of forms mostly.First kind of form loads adapter sleeve (spring loaded nipple) by the spring that is connected to mobile master carrier to be formed, and master carrier mates with recess in the electrical connector of installing against the inside of porose driving-belt.Because aspect, space, micro-dimension make system very responsive to wearing and tearing, and only allow very light valance mass loading.

Other general known form is made up of the master carrier that with the single lever arm (levered arm) that is provided with single multipurpose spring is characteristics.By pulling down the far-end of valance, the lever arm discharges stop pin from the part that is connected to driving-belt of master carrier.Like this, the valance fabric has moved with regard to available hand.

The shortcoming of this system is to have only a spring to handle valance loading functional and locking spring function.This requires spring action to be eager to excel to being enough to carry the valance load, its is kept being withdrawn into suitable position in position and with arm, but eager to excel in whatever one does to making it can stop stop pin to slip back in its connector.The use that is used for this dual-purpose single spring has seriously limited the maximum permissible load on the arm.This is normally constrained to the normal load of maximum 0.5kg at present.

The load limitations that influenced by the principle of the single arm of prior art and single spring has seriously limited motorization valance system.In a lot of examples, motorised systems is used to eliminate the manual needs to huge and heavy valance system.Weight limits seriously defines range of application.And because the ability of spring will be easy to surpass Maximum Allowable Weight, this will make load reduce the lever arm and discharge master carrier and driving-belt between connection.When connecting power supply, this will cause the fault of motorised systems.

Goal of the invention

Therefore the objective of the invention is to overcome at least some above-mentioned shortcomings of prior art systems.

Further purpose of the present invention is that the normal load ability is separated from locking mechanism, and making to increase load capacity, and can not reduce locking ability.

Summary of the invention

According to an embodiment of the invention, what a kind of valance (motordriven drapery) that is used for the motor transmission was provided breaks away from engagement type master carrier sub-assembly (disengageable master carrierassembly), and it has master carrier device part and locking device part.Locking device partly has the inclined-plane of entering (entrance ramp) and brake (detent) or groove (pocket), and the size of this groove is set to hold the mesh component that is installed to master carrier device part.The master carrier device partly has:

Be used to support the supporting arm at the guiding edge (leading edge) of valance fabric, supporting arm is by the first elastic component support, amount by the elasticity support that provided, that be used for supporting arm of first elastic component is changeable to adapt to the valance fabric of Different Weight, make supporting arm can support the guiding edge of valance fabric, and when having manual operation power to be applied to the guiding edge of fabric, do not remained on the engagement operations position, when manual operation power is applied to the guiding edge of fabric, then be displaced to the disengaging engagement by first elastic component; And

Mesh component, its size is set to fit in the braking tank (detentpocket) of locking device part, mesh component is flexibly promoted by one second elastic component, and this second elastic component is arranged between the part of the moveable part of supporting arm and described mesh component.

Second elastic component has elasticity, makes:

When mesh component is aimed at the braking tank and when supporting arm during in its position of engagement, mesh component is pushed to its position of engagement, is arranged in locking device braking tank partly;

Supporting arm causes second elastic component to be shifted fully mesh component is shifted out the braking tank of locking device part to the displacement of its disengaged position, partly breaks away from engagement to allow the locking device part from the master carrier device; And

During engagement process again, when mesh component when entering of locking device part travelled on the inclined-plane, direct force by mesh component that this inclined-plane is applied to makes mesh component move towards disengaged position, the motive force that opposing is applied by second elastic component, simultaneously, supporting arm is in its position of engagement.

The specific embodiment

At length, forward accompanying drawing now to, at first forward wherein Fig. 1, Fig. 2 and Fig. 3 to, described a embodiment according to master carrier transmission combination part of the present invention (master carrier drive block assembly) 100.The master carrier device assembly (master carrier block assembly) 100 that can be slidably disposed on head track 102 inside is made up of two critical pieces: be connected to the locking device part 101 of driving-belt (not shown) and be connected to the master carrier device part 105 of the front end of curtain fabric (not shown).

Forward Fig. 4 A-4C and Fig. 5 A-5D now to, the front view of the embodiment of master carrier device has been described, wherein need to carry of the spring function separation of the spring function of valance load from locking mechanism, this locking mechanism is connected to locking device part 101 with master carrier device 105 with can breaking away from engagement, and locking device part 101 is connected to the driving-belt (not shown).In said embodiment, the present invention has further used the

bimetallic arm

110 and 115 that is installed to master carrier apparatus main body 116.One of them short arm 110 is to be installed to main body 116 to the not removable and non-spring-loaded mode of master carrier device 105.The valance that these short arm 110 carryings are overlapping except about last inch all wt.Because it does not need for movably or spring is installed, if therefore it is to be the appropriate design of valance load, it will not be subjected to the restriction of weight.

As seeing in Fig. 5 A and Fig. 5 D, different with prior art system, the engagement among the present invention/disengaging engagement capability is to realize by the

spring

120 and 125 that uses two separation in the master carrier apparatus main body 116.Long arm 115 is supported the guiding edge of valance fabric (not shown).The arm 115 of length can surpass fixing short arm 110 and stretch out about one inch, thereby need only support the load of the fabric strip that about this last inch left and right sides is wide.

Long arm 115 is around the rotation of pivot 130 pivots and by the weight of strong load-carrying spring 120 supports with opposing valance fabric, described spring 120 is arranged in the cylinder 121 in the master carrier device, in the back of the pivot 130 of long arm 115, on the rear end 135 of long arm 115, upwards press.Long arm 115 also can be held in position by the front that spring 120 is arranged on pivot 130, and it has just upwards been pressed in the bottom of the front 132 of the arm of growing 115 like this.Though the parallel position of long arm 115 is not enforceable, in said embodiment, long arm 115 can be roughly parallel to a rail 102, and this position is determined by the brake apparatus on the master carrier apparatus main body 116 (stop) 117.

The elasticity of spring 120 can be regulated to be suitable for different vertical load bearing capacitys by dog screw (set screw) 139.In this way, required out-of-gear power can be regulated according to the weight of selected valance fabric.And, if necessary, can utilize the spring of varying strength further to increase or reduce load capacity to be suitable for designed different valances or head track.

With reference to figure 4A, 5B and 6A, master carrier device assembly 100 has been described, wherein be in the position of its normal " up " than long arm 115, pin 140 extends, because it will mesh with locking device part 101.Stop pin 140 can remain to valance driving-belt locking device part 101 with master carrier device 105 by the groove 145 in the locking device part in the middle of extending into.When meshing by this way, this stop pin is maintained at position suitable in the groove by the locking spring 125 separation, light-duty that is arranged in the groove 145 in the master carrier device 105 usually, is upwards squeezed the bottom that heads on pin 140 by the rear end 135 that is pressed in the pivotally supported long arm 115 on spring 125 bottoms.Only need the slight vertical force that makes progress on the pin 140 to keep selling 140 upwards and be engaged in the groove 145 from this light spring 125.

As described in Fig. 4 C, 5A and 6B, will cause that with the front portion that pulls the valance fabric elongated end of long arm 115 is dragged down.This allows the light spring 125 lax and reductions on the pin 140, thereby reduces pin 140 and make it break away from engagement from the valance groove 145 of deciding device part 101 with lock.This in abrupt release the connection between master carrier device 105 and the driving-belt locking device part 101, thereby allow smoothly manual unlocking and close up valance, and can not rotate driving-belt or infringement power transmission system, as described in Fig. 6 C.

Shown in Fig. 4 B, Fig. 6 D and Fig. 6 E, when hope recovered the motor transmission of valance, the startup of drive motor will guide the inclined-

plane

150 and 155 that enters that (or backward) forward of locking device part 101 tilts towards the master carrier device automatically.Shown in Fig. 4 B and Fig. 6 D, when position that long arm 115 is in its normal " up " (promptly, when valance is not when pulling), the light spring tension of second light spring 125 can allow to sell 140 and be withdrawn in its cylinder 123, even at this moment arm 115 is in the position of " up ".When being in the position of " up " than long arm 115, only need the light pressure on pin 140 tops to shift pin 140 onto disengaged position downwards, the same with the situation of locking device engagement process again partly.Then, shown in Fig. 6 E, punctual when 140 pairs of groove 145 and pins, spring 125 will make pin 140 extend in the groove 145, rebulid the pressure traction of electro-motor transmission.

As Fig. 1, Fig. 2 and shown in Figure 3, for example, stop pin 140 has a rotatable wheel 147 in that its front end is configurable, and wheel 147 can travel on the inclined surface that enters inclined-plane 150 and/or 155 of the locking device part 101 that is connected to the band (not shown).Rotatable wheel 147 can guarantee that pin 140 turns back in the groove 145 of locking device part 101 very smoothly, so that master carrier device 105 is reconnected to locking device part 101.

The default end of power transmission system stops not to be subjected to manual operations to influence, because the position is to be determined by the rotation of driving-belt.This can guarantee that the ongoing of valance accurately open and stacked position, and can keep final default expectation valance end position.These end positions can be by Silent Stop ^TM(trade mark of BTX.Inc. product, this product are used to control the valance stop position of electro-motor transmission valance) or other means are preset and are controlled.
