Description

Winding roller for curtain {ROLLER FOR CURTAIN}

The present invention relates to a winding roller for curtains, and more particularly to a winding roller for curtains that protects the rotary support ends that are easy to disassemble and assemble by a simple structure and support both ends of the film.

In general, a winding roller for a curtain, which is attached to the front of a refrigerated showcase used in a supermarket or a hypermarket, to prevent cold air exposure, or attached to a window of a home, is applied to the inside of a roller where the curtain is wound. It is a tart and has the feature of opening and closing quickly and easily.

However, such a conventional winding roller has a complicated structure, high production cost of parts, easy assembly and low production efficiency. In particular, if there is a slight angle error when the curtain is wound or unrolled on the roller, the curtain may be wound at an inclined angle and may deviate from the outside of the support of both guides or rollers. The problem of breaking the guide and the fixing member may occur.

Accordingly, an object of the present invention is to provide a winding roller for a curtain that can be easily assembled by the reduced number of parts and a simple structure, thereby reducing the manufacturing cost.

Another object of the present invention is to provide a winding roller for a curtain which can prevent the guides on both sides from being damaged while the curtain wound on the winding roller is wound at the correct position.

In order to achieve the above object, the present invention has a curtain wound on the outside of the roller supported by the support of both sides, and in the winding roller for curtain to return the rotation of the roller to the elastic force of the coil spring, A roller 20 having a predetermined protruding band 20a protruding in the longitudinal direction, and fitted to both ends of the roller, and having protruding edges 30a and 32a outwardly and having the protruding band 20a assembled to the outside. Guides 30 and 32 having mouth grooves 30b and 32b formed therein; A spring fixture 26 fixed to one end of the coil spring 22 and fitted into the roller 20 and having a concave groove 26a on the outside thereof; Another spring fixing member 24 is assembled to the other end of the coil spring 22 is characterized in that the square insert 18 is fitted to the outside while being assembled and fixed to the support 18.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view of a main part in a winding roller for a curtain according to a preferred embodiment of the present invention, and a guide 30 for supporting the roller 20 inside the supports 12 and 14 fixed to both sides of the support frame 10. And a spring fixing member 24, a coil spring 22 is inserted between the spring fixing member 24 inside the roller 20 to support the roller.

Figure 2 shows the central cross section in the state of the roller assembly of the present invention, the handle 29 is attached to the outer end of the curtain wound to the outside of the roller. According to the drawing, the coil spring 20 is inserted into the roller 20 in which the curtain is wound to the outside, the spring fixing body 24, 26 is fixed to both sides of the coil spring 20. At this time, the spring fixing member 26 fixed to the right end of the coil spring is located at the middle point of the roller 20, and the spring fixing member 24 fixed to the other end is assembled to the left end of the roller 20. The outer center has a square hole 24a. And guides 30 and 32 having protruding edges 30a and 32a outward are assembled at both ends of the roller 20, where the guide 30 assembled to the left side of the roller 20 It is assembled between the inner spring fixture 24.

On the other hand, the inside of the roller 20 has a predetermined protruding band (20a) formed along the longitudinal direction, the guides 30, 32 of both sides to be assembled to the roller 20, and the internal spring fixing body ( 26 has recessed grooves 30b, 32b, and 26a along the circumferential surface, respectively. Therefore, the both guides 30 and 32 and the spring holder 26 in the center are the same rotation when the roller 20 rotates.

Thereafter, the supports 12 and 14 are supported on the outer sides of the guides 30 and 32 on both sides, and the support frames 10 are attached to the supports 12 and 14 on both sides. Here, in the center of the support 12 on the left side, there is a penetrating square hole 12a, which is the same as the square hole 24a in the inner spring fixture 24, and the square insert 18 is also inserted from the outside. . The insert 18 has a screw hole therein and a screw 16 is fitted to engage the spring fixture 24. In addition, the support 14 on the right side has a shaft bar 14a protruding to the center and is inserted into the hole 31 of the guide 32 to support the rotation of the guide 32.

Referring to the operation of the present invention configured as described above are as follows.

First, the support frame 10 of the present invention is fixed to the front frame of the showcase or the upper side of the window, and in the opposite direction, a conventional locking mechanism (not shown in the drawing) to hang the handle 29 of the curtain is attached.

In this state, the rollers 20 are rotated while the curtains 28 wound around the rollers 20 are pulled when the handle 29 is pulled out to block the cold air and direct sunlight according to the purpose of use. At this time, the spring fixture 24 on the left side is fixed by the insert 18, but the spring fixture 26 on the right side rotates along the roller 20. Therefore, the coil spring 22 therein is continuously pulled in accordance with the rotation of the roller is generated a tensile force. After all the curtains are unfolded, the lower handle 29 is caught by the locking hole to perform the purpose of the curtain, and when walking the curtain by removing the handle from the locking jaw by the tension force of the coil spring 22 ( 20 returns the curtain 28 while rotating in the opposite direction.

As described above, the present invention is a means for fixing one end of the spring while being inserted along the protrusion band of the roller, that is, the assembly of the spring fixture is easy, the overall structure is simple and economical to lower the manufacturing cost Has an effect. In addition, it is durable and not easily broken, and easy to disassemble and assemble, it is easy to repair and adjust the elastic force of the coil spring.
