Definitions

  • the present invention relates to an electric curtain, particular to an electric curtain via accurately controlling a stop position of its covering sheet.
  • a conventional electric curtain 1 comprises a rail 10, a rolling shaft 11 pivoted on the rail 10, a power 12 applied to motivate the rolling shaft 11, and a controlling device 13 applied to control the power 12.
  • the rolling shaft 11 includes a covering sheet 111 rolled thereon.
  • the controlling device 13 includes a turning member 131 synchronizing with the rolling shaft 11, a sensor 132 applied to correspondingly sense the rotation of the turning member 131, a processing unit 133 connected to the sensor 132 to control the power 12, a counter 134 connected to the sensor 132, and a memory unit 135 connected to the processing unit 133.
  • the processing unit 133 After setting up, users draw down the covering sheet 111 again by the power 12 driving the rolling shaft 11, and then the turning member 131 is synchronically rotated for permitting the sensor 132 capable of detecting the rotation thereof and rendering the counter 134 to count the rotation number.
  • the processing unit 133 prevents the power 12 from running to impede the dropping of the covering sheet 111.
  • the processing unit 133 would trigger the power 12 to rotate the rolling shaft 11 until the revolution number counted by the counter 134 equals to the standard value saved in the memory unit 135. Therefore, the covering sheet 111 would be retracted to the upper limit position base on above preset standard data.
  • the conventional operating rationale mainly depends on the counting value executed by the counter 134 relative to the standard data saved in the memory unit 135 for lifting and dropping the covering sheet 111, so that the processing unit 133 accordingly determines the timing for stopping the power 12.
  • an accumulative imprecision of the counter 134 may be probably generated since a mal-sensing may affect the function of the sensor 132, or a facile transmission inertia between the power 12 and the rolling shaft 11 may incur an inaccurate motion and result errors produced therebetween.
  • the actual rotating quantity of the turning member 131 would inevitably deviate from the number counted by the counter 134 in a long term of using to cause the electric curtain 1 unable to precisely furl and drop the covering sheet 111 to the desired upper and lower limit positions.
  • the counter 134 forcedly interrupts the counting and has to restart its counting while resuming the power supply. In such situation, the counter 134 usually confuses the revolution number of furling the covering sheet 111 with the revolution number of lowering the covering sheet 111 and makes an inaccurately counting and even a shutdown of the controlling device 13. Thus, the conventional electric curtain 1 needs to reset the setting, which causes an inconvenient using and requires improvements.
  • the object of the present invention is to provide an electric curtain that assists in accurately suspending the covering sheet at a preferable position in each operation and increasing a convenience of using.
  • the electric curtain in accordance with the present invention mainly provides with a rail, a rolling shaft pivoted on the rail, a power located relative to the rail for driving the rotation of the rolling shaft, a zero device disposed at one side of the power, and a controlling device connected to the zero device and the power.
  • the zero device has a turning member concurrently rotated with the rolling shaft, an actuating member disposed correspondingly to the turning member, a sensor correspondingly positioned to the actuating member, and a counter connected to the sensor.
  • the controlling device includes a receiver connected to the sensor, a processing unit respectively connected to the receiver and the power, and a memory member connected to the processing unit.
  • the sensor When a covering sheet is rolled by the rolling shaft to stop at its upper limit position to trigger the actuating member every time, the sensor would generate a signal and send it to the processing unit, for which to control the counter to resume its counting to zero so as to recount the succeeding descending operation base on a standard value stored in the memory member.
  • the processing unit for which to control the counter to resume its counting to zero so as to recount the succeeding descending operation base on a standard value stored in the memory member.
  • the rolling shaft 31 includes a covering sheet 311 swiveled thereby, and the covering sheet 311 is restricted to stop extremely at an upper limit position a and a lower limit position b.
  • the zero device 33 includes a turning member 331 concurrently rotated with the rolling shaft 31, an actuating member 333 preferably installed on the turning member 331, a sensor 334 positioned correspondingly to the actuating member 333, and a counter 335 connected to the sensor 334.
  • the controlling device 34 includes a receiver 341 connected to the sensor 334, a processing unit 342 respectively connected to the receiver 341 and the power 32, and a memory unit 343 connected to the processing unit 342.
  • the power 32 could be triggered by a starter 321 which is directed to a wireless remote control or directed to a wired switch used by pressing.
  • the starter 321 in the illustration adopts a wireless remote control.
  • the actuating member 333 and the sensor 334 are coaxially disposed on an axle as illustrated.
  • the processing unit 342 receives the signal transmitted by the sensor 334, the processing unit 342 would properly stop the operation of the power 32 and control the counting of the counter 335 turning to zero.
  • the counter 335 would preset its counting.
  • the lower limit position b is directed where the covering sheet 311 is dropped to its extreme lowest position.
  • the turning member 331 would be concurrently rotated with the rolling shaft 31 to motivate the actuating member 333 to deviate from the sensor 334 as shown in Fig. 4 .
  • the counter 335 would not only synchronically count the rotating quantity of the actuating member 333 on the turning member 331 detected via the sensor 334 but also concurrently convert the quantity into a data.
  • the data would be saved in the memory unit 343 as a standard data basis for the next dropping of the covering sheet 311.
  • the power 32 drives the rolling shaft 31 to gradually move the actuating member 333 on the turning member 331 close to the sensor 334 until the actuating member 333 and the sensor 334 are aligned as shown in Fig. 6 .
  • the sensor 334 would detect the rotation of the actuating member 333 on the turning member 331 to transmit a signal to the receiver 341 to promote the processing unit 342 for stopping the power 32 from running and simultaneously zeroing the counting of the counter 335.
  • the counter 335 would resume its counting every time when the covering sheet 311 is drawn downward, thereby avoiding the mechanical inertia and cumulative errors that causes inexact downward and upward motions of the covering sheet 311 after using for a long period.
  • the present invention preferably obtains a precise controlling of the stop position of the covering sheet without frequent adjustments or settings of the covering sheet 311 in a long term of using, thus increasing a using convenience.
  • a second preferred embodiment of the present invention comprises elements, operations and functions similar to the first preferred embodiment, in which the electric curtain 3 still comprises a rail 30, a rolling shaft 31, a power 32, a zero device 33, and a controlling device 34.
  • an adjusting member 336 is disposed at one side of the zero device 33 for preferably adjusting the position of the sensor 334.
  • a governor 337 can be alternatively installed between the adjusting member 336 and the zero device 33 for controlling the output power of the adjusting member 336.
  • the position of the sensor 334 can be more delicately amended to collaborate with the actuating member 333 for achieving the merits of precisely controlling the covering sheet at the desired position, obtaining an efficient speedy adjustment, and attaining a convenient operation.
  • a third preferred embodiment of the present invention comprises elements, operations and functions similar to the first preferred embodiment, in which the electric curtain 3 still comprises a rail 30, a rolling shaft 31, a power 32, a zero device 33, and a controlling device 34.
  • the arrangement of the interrelated elements in the zero device 33 can be either performed in the configuration like the first and second preferred embodiments or performed in the configuration like this embodiment.
  • the actuating member 333 of the zero device 33 in this embodiment is set as a discrete part to separate from the turning member 331 on which a plurality of apertures 332 are equidistantly defined, and the sensor 334 is still correspondingly situated with respect to the turning member 331.
  • the sensor 334 would be able to sense the rotation of the turning member 331, and the actuating member 333 would be triggered by the furling of the covering sheet 311 stopping at the upper limit position a.
  • the covering sheet 311 is firstly dropped to the lower limit position b for the sensor 334 to simultaneously sense the relative rotation of the turning member 331, enhancing the counter 335 to convert the rotation into a data for the memory unit 343 to save as a standard data basis serving for the succeeding dropping basis of the covering sheet 311.
  • the processing unit 342 would thence impede the power 32 from operating and stop the covering sheet 311 at a proper position when the rotating number of the turning member 331 counted by the counter 335 equals to the standard data basis saved in the memory unit 343.
  • the covering sheet 311 when the covering sheet 311 is retracted or furled to the upper limit position a, the covering sheet 311 propels the actuating member 333 for the sensor 334 to directly emit a signal; whereby, the receiver 341 receives the signal from the sensor 334, and the processing unit 342 accordingly impedes the driving of the power 32 and concomitantly resumes the counting of the counter 335 to zero. Therefore, the counter 335 recounts when every time the covering sheet 311 is dropped.
  • the present invention takes advantages of the actuating member of the zero device cooperating with the correlated sensor.
  • the covering sheet furled to the upper limit position would force the sensor to emit a signal to the controlling device for stopping the power and returning the counting of the counter to zero, which benefits a newly counting in pursuance of a next descent of the covering sheet.
  • the present invention decreases an accumulative error resulting from inaccurate movements of the covering sheet after using for a long time for ensuring a precise suspension of the covering sheet and promoting an operative convenience.
