The present invention relates to a winding device, and more particularly, to a winding device that allows the user to operate a traction line at any angle, as well as to smoothly and smoothly lift a roll screen or curtain regardless of its size or weight. .

Conventional winding devices are configured to transmit the rotational force directly to the winding roller when the driving pulley is rotated by pulling the traction line, so that the load due to the weight of the screen or curtain is caught on the driving pulley and is operated when it is large and heavy. It took a lot of effort, and there was a defect such as frequent failures due to excessive manipulation.

In addition, in order to prevent the winding roller from being reversely rotated and the rolled screen or curtain unrolled, a braking piece was mounted and a traction line was attached.If the braking piece is overloaded, its function is lost and the reverse rotation is effectively performed. There were also disadvantages that could not be prevented.

In addition, when the attachment state is changed from vertical to horizontal or vice versa, the winding device must be disassembled to change the exposure direction of the tow line, and the tow operation angle of the tow line is limited to the vertical line. There were also drawbacks such as many restrictions on operation.

The present invention has been devised in view of the above-described points of the conventional winding device, and an object thereof is to provide a winding device that can always smoothly and smoothly lift with a small force regardless of the size or weight of a roll screen or curtain. .

Another object of the present invention is to provide a winding device in which the roll screen or the curtain is arbitrarily prevented from being released and the installation angle or the range of the operation angle of the traction line is widened.

This object of the present invention is achieved by providing a winding device in which the rotational force of the driving pulley rotated by the operation of the tow line is shifted and transferred to the take-up roller, and the towing operation angle of the tow line is freely changed and the reverse rotation is reliably prevented. This winding device is equipped with a planetary gear device for shifting the rotational force of the driving pulley to the winding roller, and a braking member for preventing the winding roller from rotating backward.

The planetary gear device includes a movable sun gear integrally formed at the center of the driving pulley, a plurality of planetary gears which are squeezed onto the electric shaft tube to be inscribed by the movable sun gear, and a gear pipe part attached to the outer surface of the main body so that the planetary gears are externally oriented. It consists of fixed sun gears formed on the inner circumferential surface of the.

The braking member is a torsion spring and is coupled to the outer circumferential surface of the shaft pipe portion attached to the inner surface of the main body.

The outer side of the driving pulley is axially coupled to the cylindrical cover body provided with a distribution hole of a traction line spanning the driving pulley, and the tubular tube portion is coupled with a tubular body coupled with the front end of the electric shaft tube. A binding tube to which one end of the winding roller is bound is coupled.

Therefore, when the winding roller is rotated by manipulating the traction line, the rotational force is transmitted to the planetary gears by the movable sun gear, and since the planetary gears are internal and external to these gears between the movable and fixed sun gears. Rotating and rotating the electric shaft tube is rotated in this process, while the rotational speed is reduced while the rotational force is strong, the rotational speed of the electric shaft tube is slower than the rotational speed of the drive pulley, As it rotates with a large force, it can smoothly lift large and heavy roll screens and curtains, and when the winding roller tries to reverse rotation, the binding tube tightens the torsion spring, so that this spring is firmly adhered to the outer peripheral surface of the shaft part. As it prevents the binder pipe from rotating in reverse, it is impossible to reverse the winding roller. Prevention is, the cover body being gyeoninjul this distribution is geotyieoseo a shaft coupled to be rotated free it is possible to operate at any angle depending on the angle of exposure is changed gyeoninjul freely.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an example of a conventional winding device.

The winding apparatus includes a main body 1 having a polygonal engaging hole 1a and a supporting plate body 2 having a polygonal engaging piece 2a coupled to the engaging hole 1a, with a shaft hole 2b formed in the center thereof. On one side, a shaft 3a coupled to the shaft hole 2b protrudes, and on the other side, a binding shaft 3b protruding from one end of the take-up roller is protruded and the pulley 4 extends over the pulley 4; A shaft hole 5a through which the binding shaft 3b penetrates is formed at the center thereof, and a cover 5 having a distribution port 5b of the tow line 4 formed at the outer circumferential surface thereof, and an inner shaft portion of the distribution port 5b. It consists of the braking pieces 6 provided with the through-hole 6a of 4).

Therefore, such a winding device rotates the drive pulley 3 by manipulating the traction line 4, so that the rotational force is transmitted directly to the winding roller fastened to the binding shaft 3b. The load was caught by the drive pulley 3 as it was, and a lot of power was required to operate, and the winding operation was not performed smoothly.

In addition, since the lid 5 is fixedly coupled to the support plate 2, in order to change the attachment state of the main body 1 from vertical to horizontal or vice versa, in order to change the exposure direction of the tow line 4 to a vertical line. It was necessary to separate the support plate body 2 from the main body 1, change the direction of the distribution port 5b of the cover body 5, and refit it.

In addition, since the traction operation angle of the traction cord 4 is limited to the vertical line as shown in FIG. 2, since the operation must be performed directly under the traction line 4, there are many restrictions on the installation position of the main body 1 and the user's operation position selection. It became.

In addition, when the winding roller is about to be reversed arbitrarily, the braking piece 6 hangs the traction line 4 so that the reverse rotation of the driving pulley 3 is prevented so that the winding roller is not reversed. When the overload is applied, the sliding phenomenon occurs, so the braking piece 6 cannot stiffly pull the tow line 4, thereby losing the braking function.

In addition, the center of the tube portion is in communication with the axial through-hole 16, the control jaw 17, 17 'is formed on both sides of the outer surface of the coupling piece (11).

Then, the driving pulley 20 and the cover body 30 surrounding and enclosing the pulley are rotatably compressed on the outer surface of the coupling piece 11.

In the main surface portion of the drive pulley 20, the hooking groove 21 of the traction cord 40 is formed roundly, and an inner surface of the coupling portion 22 to which the gear pipe portion 13 is coupled is concave and formed in the center thereof. The gear 23 is integrally formed to protrude.

In addition, on the inner circumferential surface of the coupling portion 22, a binding protrusion 24 fitted into the binding groove 15 protrudes roundly, and a shaft pin through hole 25 is formed in the center thereof.

The cover 30 has a cylindrical shape, and a binding shaft pin 31 having a binding jaw 32 formed at the front end at the center of the inner surface protrudes through the through hole 25 to be coupled to the through shaft. A control protrusion 33 which is selectively walked at (17) (17 ') is formed to protrude, and a distribution hole 34 of the traction cord 40 is installed to vertically penetrate the center of the control protrusion.

On the other hand, the shaft through-hole 16 is coupled to the transmission shaft tube 50, the braking member 60 is coupled to the outer surface of the shaft tube portion (14).

At the rear end of the transmission shaft tube 50, a support disk 51 having a diameter larger than that of the shaft through-hole 16 is integrally formed, and in the center of the disk, a binding shaft pin 31 is formed with a through-hole 52. On the outer circumferential side of the ball, a plurality of shaft pins 53 protrude at regular intervals.

In the shaft pins, planetary gears 54 are fixed to the movable sun gear 23 and the fixed sun gear 12 inward and outward.

In addition, a binding surface 55 is formed in a planar shape at a position corresponding to each other on the outer peripheral surface of the tip end portion of the transmission shaft tube 50, and the binding protrusions 56 protrude on the outer peripheral surface between these binding surfaces.

And, in the middle of the binding surface 55, the cutting grooves 57 are formed to open to the tip.

The braking member 60 is a torsion spring, and the hook portions 61 and 61 ', which bend both ends outward, are isolated at appropriate intervals.

On the other hand, the shaft tube portion 14 is coupled to the transmission tube 70 and the binding tube 80 of the winding roller 110.

In the transmission tube 70, a binding hole 71 through which the binding surface 55 is penetrated is installed, and on the outer circumferential surface, the engaging portions 72, 72 'are hooked by hooks 61, 61'. It is isolated at intervals slightly larger than the interval between them.

Therefore, when the transmission tube 70 is coupled to the shaft tube portion 14, the locking step (72, 72 ') is located outside the hook portions (61, 61').

The binding tube 80 is coupled to surround the transmission tube body 70, and a through hole 81 is formed at the center of the front end surface through which the tip portion of the transmission shaft tube 50 passes.

In addition, the outer circumferential surface is formed with binding grooves 82 in which the binding protrusions formed in the end of the winding roller 110 are formed, and the braking protrusion 83 protrudes inwardly on the inner circumferential surface.

The braking stepped portions 84 and 84 'at both ends of the braking protrusion have a smaller spacing than the spacing of the hook portions 61 and 61'.

Therefore, when the binding tube 80 is coupled, the braking protrusions 83 are positioned between the locking step portions 72 and 72 ', and the braking step portions 84 and 84' are hooked portions 61 and 61 '. ) Will be located inside.

That is, the hook portion 61 is located between the engaging step 72 and the braking step 84, the hook portion 61 'is located between the engaging step 72' and the braking step 84 ', At the same time, an appropriate gap t (t ') is formed between the hook portion 61 and the braking step 84, or between the hook portion 61' and the braking step 84 'according to the rotational direction due to the difference in these gaps. Retained (see also sixth (a) and sixth (b)).

The winding device according to the embodiment of the present invention configured as described above is assembled as shown in FIG. 4, and at the time of assembly, the front end portion of the electric shaft tube 50 first opens the shaft through-hole 16 of the main body 10 from the outside to the inside. The support disk 51 is inserted into the gear tube portion 13 so as to penetrate through the outer surface of the shaft through hole 16, and the planetary gears 54 are fixed to the respective shaft pins 53 to fix the fixed sun gears 12, respectively. Next, the planetary gears 54 are internally coupled to the movable sun gear 23 at the same time as the gear tube 13 is coupled to the coupling portion 22 of the driving pulley 20.

In this way, the binding protrusions 24 formed on the inner circumferential surface of the coupling portion 22 are fitted into the binding grooves 15 formed on the outer circumferential surface of the gear tube portion 13 so that the driving pulley 20 is the gear tube portion 13. At the same time, it is bound to the gear tube portion 13 as the axis, and the planetary gears 54 are engaged to engage them between the movable and fixed sun gears 23 and 12.

In this state, the tow line 40 is applied to the latching groove 21 of the driving pulley 20, and both ends of the tow line are drawn out from the inside to the outside through the distribution hole 34 of the cover body 30, and the cover The cover body 30 is driven through the shaft pin through-hole 25 of the driving pulley 20 and the through-hole 52 of the electric shaft pipe 50 through the mounting shaft pin 31 of the inner surface of the sieve 30. Combine on the outside.

When coupled in this way, the driving pulley 20 is completely covered by the cover body 30, and the binding jaw 32 at the tip of the binding shaft pin 31 passes through the through holes 25 and 52 through the through hole. Since it is hooked on the inner end surface of the 52, the cover body 30 is coupled freely and freely by the binding shaft pin 31 while being coupled not arbitrarily.

Next, the braking member 60 is coupled to the outer circumferential surface of the shaft tube portion 14, and the transmission tube 70 is positioned so that the locking step jaws 72 and 72 ′ are positioned outside the hook portions 61 and 61 ′ at both ends thereof. ) Is coupled to the shaft tube portion 14, and at the same time to pass through the binding hole 71 of the binding surface 55 of the tip of the electric shaft tube (50).

In this case, by the surface binding of the binding surface 55 and the binding hole 71, the transmission shaft tube 50 and the transmission tube 70 are coupled to rotate together.

In this state, when both braking stepped portions 84 and 84 'of the braking protrusion 83 are coupled to the binding tube 80 so as to be positioned inside the hook portions 61 and 61', the binding tube is a transmission tube 70. ) Is completely wrapped and at the same time the tip end of the electric shaft tube 50 passes through the through hole 81 so that the binding protrusions 56 of the tip are walked on the outer circumferential surface of the through hole 81, thereby (70) And binding tube 80 is rotated coupled to the shaft tube portion 14 so as not to be separated arbitrarily.

After coupling in this way, if the outer diameter is slightly larger than the inner diameter of the distal end portion of the electric shaft tube 50 and the fixing pins (90) protruding from the fixing projections (91) fitted in the incision groove (57) are attached to the distal end peripheral surface. , The binding pipe 80 is more tightly coupled by the binding protrusion 56 and the fixing pin 90.

The winding device according to the embodiment of the present invention, which is assembled as described above, uses one end of the winding roller 110 of the roll screen 100 to be attached to the binding pipe 80, and installs the roll screen 100 as shown in FIG. When it is to be raised and lowered, the pull line 40 may be pulled in the required direction. At this time, the driving pulley 20 may be rotated forward to raise the roll screen 100, and may be reversed to lower.

When the driving pulley 20 is rotated in this way, the rotational force is transmitted to each of the planetary gears 54 by the movable sun gear 23 as shown in FIG. 5, and the planetary gears are movable and fixed sun gears ( 12) inside and outside, so they rotate and revolve between them.

Accordingly, when the planetary gear 54 revolves, the electric shaft tube 50 is rotated, and the rotational force is transmitted to the electric tube body 70 by the binding surface 55 and the binding hole 71 which is bound in surface contact with it. do.

Of course, in this process, the rotational speed of the drive pulley 20 is decelerated in proportion to the difference in the number of gear teeth by the movable and fixed sun gears 23, 12 and the planetary gears 54, but inversely the rotational force is Get stronger.

On the other hand, when the rotating tube 70 is rotated according to the rotation direction, that is, counterclockwise as shown in FIG. 6 (a), the locking step 72 'is the hook portion 61 of the braking member 60. ') Is pushed, as the hook portion pushes the braking step 84' of the braking protrusion 83, the binding pipe 80 is rotated, and the winding roller 110, which is bound thereto, rotates. The braking member 60 is rotated without the braking action because the hook portion 61 'is pushed in the releasing direction rather than tightening the braking member 60.

In addition, this action occurs even when the driving tube 70 is rotated in the clockwise direction as shown in FIG. 6 (b) to push the hook portion 61.

Therefore, when the driving pulley 20 is rotated forward and backward to rotate the electric tubular body 70, the rotational force is normally transmitted to the winding roller 110 via the binding pipe 80, so that the roll screen 100 is elevated. It will be made.

However, when attempting to directly rotate the overload due to the weight of the roll screen 100 or the take-up roller 110, at this time, the binding tube 80 is clocked according to the rotation direction, that is, as shown in the virtual arrow of FIG. If it is to be rotated in the direction, the direction in which the braking step 84 pushes the hook portion 61 'becomes the direction for tightening the braking member 60. Therefore, the braking member is tightened to firmly rest on the outer circumferential surface of the shaft tube portion 14. Because of the binding, the binding tube 80 is prevented from rotating.

This action also occurs when the binding tube 80 is to be rotated counterclockwise as in the virtual arrow of FIG. 6 (b).

Therefore, the winding roller 110 is to be braked so that it can not be directly rotated without operating the tow line 40.

On the other hand, since the lid 30 is axially coupled to be freely rotated by the binding shaft pin 31, as shown in FIG. 7, the operation angle of the tow line 40 is changed freely according to the position of the user so that the operation is performed. It is very convenient, and the degree of change is controlled so as not to be excessively changed by the control jaw 17, 17 'and the control protrusion 33 selectively hooked on these jaws.

Winding device according to the embodiment of the present invention that is operated as described above, the rotational force of the drive pulley is shifted by the sun gears and planetary gears at the same time to be strengthened and transmitted to the winding roller to easily carry a heavy roll screen or curtain with a small force As well as being able to lift, there is an advantage that the lifting operation is always performed smoothly and smoothly.

In addition, since the operation angle of the tow line is changed freely according to the user's position, it is not limited to the installation position or the operation position, which is very convenient, and the cover body is disassembled to change the exposure direction of the tow line when the installation position is changed. There is no need to combine, which makes installation very simple.

In addition, since the winding roller is reliably braked without using the traction line, it is a very useful design such that the closed roll screen or the curtain is dropped as well as the closed end is arbitrarily lowered.
