Description

Winding device for blinds {APPARATUS FOR WINDING A BLIND}

The present invention relates to a winding device for blinds, and more particularly, to a winding device for blinds which reduces a user's workload and weight.

In offices, homes, and restaurants, blinds are used as curtains. Generally, blinds are widely used to block light emitted from the outside to the interior side, or to block the view from the outside in consideration of privacy and aesthetics by installing the blind separately on the interior side of a door or window. .

As shown in FIG. 1, the general blind is wired by the follower 20 receiving the force from the drive unit 10 when the user applies a force to the drive unit 10 including the ball chain 12. The predetermined slits S are raised and lowered as the P is pulled or released.

The configuration and operation of such a general blind will be described schematically with reference to FIG.

The drive unit 10 includes a sprocket 14 having a ball chain 12 wound around its outer circumferential surface, a drive gear 16 and a side cover 18 coupled to one surface of the sprocket 14. The side cover 18 is composed of a left side cover 18a and a right side cover 18b, and a tubular housing 19 having a driven gear 19a formed on an inner circumferential surface of one side of the left side cover 18a is formed. do. The drive gear 16 protrudes into the housing 19 through a hole formed in the left side cover 18a, and a predetermined distance is formed from the driven gear 19a formed on the inner circumferential surface of the housing 19.

On the other hand, the driven part 20 is driven gear 22 mounted in the gap formed between the drive gear 16 and the driven gear 19a, and prevents the driven gear 22 from being separated from the inside of the housing 19 The latching protrusion 24a protrudes from one surface so as to be caught by the rotating driven gear 22 so as to receive the rotational force, and a driving wheel 24 having one end of the upper bar 30 fixedly coupled to the center thereof.

General operation of the blinds including the above configuration will be described schematically. When the user pulls the ball chain 12, the sprocket 14 and the drive gear 16 are rotated, and the driven gear interlocked between the drive gear 16 and the driven gear 19a according to the rotation of the drive gear 16. (22) is rotated, the driven gear 22 is caught by the engaging projection (24a) and the rotational force is transmitted to the drive wheel (24). Accordingly, the upper bar 30 coupled to one end of the driving wheel 24 also rotates to wind or unwind the wire (see FIG. 1), and the slit (see FIG. 1) is raised or lowered.

However, this general blind is the wire is wound on the top bar 30 as the user raises the slits with the slits fully released from the top bar 30, at this time the weight of the slit was supported by the wire itself There is a problem in that the weight that the user must bear is increased, and in particular, in the case of wood blinds made of slit wood, the weight felt by the user is added. In addition, the number of revolutions of the upper bar 30 is determined by the number of revolutions of the drive wheel 24, and the number of revolutions of the drive wheel 24 is determined by the number of revolutions of the driven gear 22. Since the rotation speed of the 22 is much smaller than the rotation speed of the drive gear 16, in order to elevate the slit by the amount desired by the user, the length of the ball chain 12 must be pulled to increase, and thus the user There was a problem that the work load increased.

The matters described as the background art are only for the purpose of enhancing the understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the related art already known to those skilled in the art.

The present invention reduces the weight felt when the user pulls the ball chain by using a spring spring to solve this conventional problem, and transmits the driving force directly to the rotary shaft without transmitting power by a separate driven gear. The purpose of the present invention is to provide a blind winding for reducing the user's workload.

The blind winding according to the present invention for achieving this purpose is a housing in which one side is open and the other side is formed with a through hole; Sprockets are formed on the outer circumferential surface in the circumferential direction and in contact with the outside of the other surface of the housing; A ball chain wound around one end of the groove to rotate in an endless track; A rotation shaft having one end fixedly coupled to the sprocket 200 and formed to extend in a transverse direction through a through hole of the housing; A blind positioned parallel to the lower side of the rotary shaft and including a plurality of slits connected by wires having one end fixed to the rotary shaft; One end is fixed to the rotating shaft that traverses the inside of the housing 100, and the other end includes a spring spring fixed to one surface of the housing.

An insertion hole is formed in one side of the housing, and the other end of the spring spring is fixed to an outer circumferential surface of the housing through the insertion hole.

A disc is formed in the center and coupled to an open side of the housing, a coil spring mounted on an inner circumferential surface of the housing hole of the disc, and fixed to the rotary shaft by being fitted to both ends of the coil spring. The outer circumferential surface may further include a brake including a disk shaft on which an engaging protrusion is formed so as to be caught.

The rotary shaft may include a rotary bar having one end fixedly coupled to the sprocket, and a support bar having one end passing through the disc shaft, and a connecting member having the rotation bar and the support bar provided between the housing and the disc.

The spring is characterized in that the width increases from one end to the other end.

The spring is characterized in that the thickness increases from one end to the other end.

The present invention can reduce the weight when the user pulls the ball chain due to the above technical configuration. Furthermore, since the driving force is directly transmitted to the rotary shaft, the user's workload is reduced, and since complicated parts such as driven gears can be omitted, cost is reduced and assembly performance can be improved.

Hereinafter, with reference to the accompanying drawings looks at with respect to the blind winding in accordance with a preferred embodiment of the present invention.

As shown in Figure 3, the blind winding according to the present invention includes a housing 100, sprocket 200, ball chain 300, rotary shaft 400, blind 500 and spring spring 600 do.

One surface of the housing 100 is open, and the other surface is formed with a through hole (100a). On the other surface of the housing 100, the extension part 110 is bent in the longitudinal direction thereof, and a space in which one end of the sprocket 200 and the ball chain 300 to be described later is formed is formed. Therefore, the housing 100 is provided with a space formed by one open surface and another space formed by the extension 110.

The sprocket 200 is mounted in a space formed on the other surface of the housing 100. The sprocket 200 is formed with a groove 200a on the outer circumferential surface thereof. In addition, one side of the sprocket 200 is inserted into the through hole 100a of the housing 100 so that the rotary shaft 400 can be easily inserted to form a fitting hole protruding so that the rotary shaft 400 can be easily fitted. Can be.

The groove 200a formed on the outer circumferential surface of the sprocket 200 is caught by one end of the ball chain 300 which rotates on the groove 200a in an infinite orbit. That is, the upper end of the ball chain 300 is caught in the groove 200a of the sprocket 200, the lower end is formed so that the user can pull. The side cover 900 is coupled to the extension 110 of the housing 100 in a state in which the ball chain 300 is caught in the sprocket 200 and the groove 200a of the sprocket 200.

The rotary shaft 400 is formed long in the lateral direction, and one end of the rotary shaft 400 is fixedly coupled to one surface of the sprocket 200 by passing through the through hole 100a of the housing 100. When the fitting holes 210 are formed on one surface of the sprocket 200, one end of the rotary shaft 400 may be more easily coupled to the sprocket 200.

Rotating shaft 400 formed in such a transverse direction is located in the upper cover 910, the lower surface is open. Slit 510 formed in the transverse direction is continuously positioned in the longitudinal direction of the rotary shaft 400, each slit 510 is sewn with a wire (W) end is coupled to the rotary shaft 400 blind ( 500). Therefore, when the rotary shaft 400 is rotated so that the wire W is wound or unwound by the rotary shaft 400, the blind 500 is also elevated.

The spring spring 600 is mounted inside the open one surface of the housing 100. One end located inside the spring spring 600 is fixedly coupled to the rotary shaft 400, and the other end located outside the spring spring 600 is fixedly coupled to the housing 100. The spring spring 600 is mounted in an undeformed state in which the blind 500 is fully raised, and is gradually deformed as the spring 500 is wound around the rotating shaft 400 when the blind 500 is lowered. If 500 is completely lowered, the degree of deformation is maximum. Therefore, when the ball chain 300 is pulled to raise the blind 500 again, since the restoring force of the spring spring 600 may be used, the weight felt by the user is reduced.

In addition, it is preferable to form an insertion hole 100b on one side of the housing 100. Since the space inside the open one surface of the housing 100 is narrow, it is very difficult to fix the other end of the spring spring 600. Therefore, when the other end of the spring spring 600 passes through the insertion hole 100b and is fixed to the outer surface of the housing 100, convenience of work is enhanced.

On the other hand, when the user lifts the blind 500, the blind winding for the blind 500 may further include a brake 700 so as to stop at the desired position.

The brake 700 includes a disk 710, a coil spring 720 and a disk shaft 730. The disk 710 is coupled to an open surface of the housing 100, and a receiving hole 710a is formed at the center thereof, and the coil spring 720 is mounted at the receiving hole 710a. Both ends of the coil spring 720 are bent in the direction of the center of the receiving hole 710a. In addition, the disk shaft 730 to which the rotary shaft 400 is fitted is located on the receiving hole (710a), the outer circumferential surface of the disk shaft 730, the locking projection so that both ends of the coil spring 720 can be caught during rotation 732 is formed. Therefore, when the user pulls the ball chain 300 to elevate the blind 500, the sudden or excessive rotation of the rotation shaft 400 causes the locking protrusion 732 formed on the disc shaft 730 to become the coil spring 720. This is prevented by jamming both ends of the.

Rotating shaft 400 is preferably composed of a rotation bar 410 and a support bar 420 to improve the assembly. Rotating bar 410 is one end is fixedly coupled to the sprocket 200, when the fitting hole is formed in the sprocket 200, one end is fitted to the fitting hole is coupled. In addition, the support bar 420 is fitted to the disk shaft 730 and extends. In order to transfer the rotational force of the rotation bar 410 to the support bar 420, the other end of the rotation bar 410 and one end of the support bar 420 are connected using the connection member 800 having a hole in the center thereof.

On the other hand, as shown in Figure 4, the spring spring 600 is preferably formed so as to increase in width from the other end (outside) to one end (inside). The spring spring 600 is mounted in a state in which the slits 510 constituting the blind 500 are completely deformed and then deformed while the slits 510 are lowered to reach the bottom end thereof. Then, when the blind 500 is raised, the longer the length of the rise, the weight of the slits 510 is added, so that the restoring force required for the spring spring 600 increases. Considering this point, if the spring spring 600 is formed to increase in width from the outside to the inside, a larger restoring force can be obtained as the blind 500 rises.

In addition, as shown in FIG. 5, when the spring spring 600 is formed to increase in thickness from the other end (outside) to one end (inside), the same effect as varying the width of the spring spring 600 is obtained. Can be.

Although the present invention has been shown and described in connection with specific embodiments, it is understood that the present invention can be variously modified and changed without departing from the technical spirit of the present invention provided by the following Utility Model Registration Claims. It will be obvious to those of ordinary skill in the industry.
