1 is an exploded perspective view of a string length adjusting device according to a first embodiment of the present invention, Figure 2 is a plan view of the coupled state of FIG.

As shown in these figures, the string length adjusting device of the present embodiment, the first and second housings (100,200) and the first and second housings (200, 200) which are provided to be coupled to each other detachably coupled to each other when the side portion is penetrated. The winding unit 300 is provided to be partially accommodated in the 100,200.

The first and second housings 100 and 200 are portions that form an appearance of the string length adjusting device when they are coupled to each other.

Each of the first and second housings 100 and 200 may be bent from side surfaces of the first and second plate portions 110 and 210 and the first and second plate portions 110 and 210 to be detachably coupled to each other. 2 skirt portions 120 and 220 are provided.

Therefore, when the first and second housings 100 and 200 are coupled, the remaining area except for the first and second skirt parts 120 and 220 becomes an empty space.

The same applies to the first and second skirt portions 120 and 220, but in particular, the first and second plate portions 110 and 210 may be made of a material having a thin thickness and capable of retaining its own elasticity.

Looking at the direction of elasticity, the first and second plate surface parts 110 and 210 may have elasticity in a direction capable of elastically pressing the winding unit 300 disposed therebetween.

The first and second plate surface parts 110 and 210 are manufactured to have an approximately circular shape in which the overall shape is convex at the center in the rectangular shape. However, the present invention is not necessarily limited to the drawings, and the first and second plate surfaces 110 and 210 may have a simple rectangular shape.

The first and second skirt portions 120 and 220 are used as portions for coupling the first and second housings 100 and 200 to each other. The mutual coupling structure of the first and second skirts 120 and 220 preferably has a hook engagement coupling structure, which will be described later.

Of course, since the drawings shown in FIG. 1 do not limit the scope of the present invention, both the first and second skirt portions 120 and 220 are not necessarily provided in both the first and second housings 100 and 200.

For example, only the first plate portion 110 is formed in the first housing 100, and the second skirt portion 220 formed in the second housing 200 includes the first plate portion of the first housing 100 ( 110 may be applied to the structure coupled to the hook type side. Of course the opposite is also true.

Meanwhile, the winding unit 300 provided to be partially accommodated in the first and second housings 100 and 200 may protrude from the disc portion 310 and the upper surface of the disc portion 310 to form the first housing 100. The head portion 320 partially accommodated on the inner surface of the first plate portion 110 and the lower surface of the disc portion 310 protrude from the inner portion of the second plate portion 210 of the second housing 200. And a winding rod 330 in which a line (not shown in this embodiment, L in FIG. 4) inserted through the first and second housings 100 and 200 is wound and unwound.

The first and second housings 100 and 200 may be partially accommodated in the first and second housings 100 and 200, and may be coupled between the first and second housings 100 and 200, and may be rotated in positions. Inner surfaces of the first and second plate portions 110 and 210 of the first and second groove portions 110a and 210a to which the upper end of the head 310 and the lower end of the winding rod 330 are fitted are formed.

And a disc contacting each other so that the string L can be wound and unwound on the winding rod 330 based on the rotation in the forward and reverse directions of the winding unit 300 located in the first and second housings 100 and 200. One of the upper surface of the portion 310 and the inner surface of the first plate surface portion 110 has a projection 311, the other is formed with a projection groove 111 to selectively fit the projection 311.

In the present embodiment, both the projection 311 and the projection groove 111 is provided in plurality, the projection 311 is on the upper surface of the disc portion 310, and the projection groove 111 is the first plate surface portion 110 It is formed on the inner surface of the.

However, the objection is not to limit the scope of the present invention. That is, the protrusions 311 and the protrusion grooves 111 may be formed in the first plate portion 110 and the disc portion 310, respectively. Particularly, in the case of the protrusions 311, the protrusions 311 and the protrusion grooves 111 may be provided. It can be fully implemented.

On the other hand, in the present embodiment to wind or unwind the rope (L) in the winding rod 330, the winding unit 300 must be rotated in the forward and reverse directions.

To this end, the diameter of the disc portion 310, which is one configuration of the winding unit 300 in the present embodiment, the first and second plate portions 110 and 210 having the largest diameter in the first and second housings 100 and 200. It is formed larger than the diameter of the outer circumferential surface is exposed to the outside of the first and second plate portion (110,210), the outer circumferential surface of the exposed disc portion 310 is a string (L) when rotating in the forward and reverse direction of the winding unit 300 It is used as a handle for winding and unwinding.

In other words, when proceeding to rotate the winding unit 300 in the forward and reverse direction, grab the outer surface of the hatched hatched portion shown in Figure 2 (this part is the exposed portion of the outer peripheral surface of the disc portion 310) Just do it. Therefore, it may be more advantageous for the operation to make the diameter of the disc portion 310 as wide as possible under the same conditions.

In more detail, when the first and second housings 100 and 200 are combined, the remaining area except for the first and second skirt portions 120 and 220 becomes an empty space, and the hatched hatches shown in FIG. Since the outer circumferential surface of the disc portion 310, which is a portion, is exposed, the user may grasp and rotate this portion.

When such a structure is applied, the user can rotate the take-up unit 300 while holding a larger area, so that it is possible to implement the winding and unwinding operation of the string L with less force and easier form. will be.

For reference, in the present embodiment, the description thereof is omitted, but may be in the form of winding the outer surface of the winding rod 330 when the rope (L) is wound, or a separate hole (hole) in the winding rod 330 After forming, the string L may be wound to the outer surface of the winding rod 330 through this hole.

As described above, according to the present embodiment, the length of the string L can be adjusted conveniently and effectively while having a simple and simple structure.

Hereinafter, another embodiment of the present invention will be described with reference to the accompanying drawings, in which the following embodiments, some structures are applied as an embodiment different from the first embodiment, the winding of the line (L) and The parts used as handles when unwinding are the same as the outer circumferential surface of the disc part 310. Therefore, the description of this part will be replaced with the description of the first embodiment.

3 is an exploded perspective view of a string length adjusting device according to a second embodiment of the present invention;

In the present embodiment, a spring 400 for pressing the winding unit 300 toward the first housing 100 is further provided between the winding rod 330 and the second groove 210a.

The spring 400 is disposed between the winding rod 300 and the second housing 200 to elastically press the winding unit 300 toward the first housing 100.

Of course, as described above, when the second housing 200 is made of a material that plays the role of a spring, that is, even if the second housing 200 is made of thin plastic having elasticity, the operation is sufficiently possible. When the spring 400 is applied as in this embodiment, since the spring 400 elastically presses the winding unit 300 toward the first housing 100 side, the winding unit 300 tries to rotate arbitrarily. The phenomenon can be prevented. That is, since the engagement operation of the above-described protrusion 311 and the protrusion groove 111 is not released arbitrarily, the phenomenon that the string L is arbitrarily released is prevented.

In particular, the structure as shown in FIG. 3 may be more advantageous to apply to the structure of the screw parts 410 and 420 of the embodiment shown in FIG. 4, deviating from the structure of the protrusion 311 and the protrusion groove 111.

Meanwhile, although not shown in FIG. 3, when the spring 400 is simply disposed between the winding rod 300 and the second housing 200 as shown in FIG. 3, since the spring 400 may be separated, the spring 400 may be blocked. To this end, it is preferable to further form a separate fitting protrusion (not shown) fitted to the spring 400 at the lower end of the winding rod 300 and the second groove 210a, but it is not necessary to do so.

For reference, although the spring 400 is made of a coil spring, it may be replaced by a leaf spring.

4 is a schematic cross-sectional view of a string length adjusting device according to a third embodiment of the present invention.

In the case of the first embodiment described above, the protrusion 311 is selectively fitted to one of the upper surface of the disc portion 310 which is in contact with each other and the inner surface of the first plate surface portion 110, and the protrusion 311 is selectively fitted to the other. Protrusion groove 111 was formed.

However, the structure of the projection 311 and the projection groove 111, the first screw portion 410 formed on any one of the upper surface of the disc portion 310 and the inner surface of the first plate portion 110, which are in contact with each other, It may be changed to the structure of the second threaded portion 420 is formed on the other one and screwed to the first threaded portion 410 and mutually.

That is, it may have a structure as shown in enlarged in Figure 4, in this case, the first and the first so that the winding unit 300 is not randomly rotated in the direction in which the unwinding line (L) wound on the winding rod 330 The two threaded portions 410 and 420 are machined in a slanted direction. In other words, the first and second threads 410 and 420 have a form of one way threads eccentrically to one side.

As such, when the first and second threaded portions 410 and 420 have the form of one-way threads, the slant is wound toward the gentle side, that is, in the direction in which the string L is wound on the winding rod 330. Although the unit 300 can be easily rotated, the winding unit 300 is limited to the rotation in the opposite direction.

The number and size of the first and second threads 410 and 420 may be appropriately designed as necessary.

On the other hand, due to the structural features of the first and second threaded portion (410, 420) winding unit 300 is not arbitrarily rotated, that is, if necessary, that is, the string (L) should be loosened.

In this case, since the winding unit 300 is difficult to simply rotate, the release unit 500 may be used. In other words, the release unit 500 serves to easily or forcibly release the engagement state of the first and second screw portions 410 and 420 which are screwed to each other.

The release unit 500 may be implemented in various forms, but in the present embodiment, the release unit 500 may include a through hole formed in the center of the first plate surface part 110 to partially expose the head 320. It is disposed in the region 510 may be applied as a pressing member (not shown) to elastically press the head 320 to the second housing 200 side. The pressing member is preferably made of a material having a predetermined elastic force.

When such a release unit 500 is applied, if you want to forcibly release the engagement state of the first and second screw portions 410 and 420 engaged with each other, it is easy to proceed simply by forcing the pressing member.

Of course, in addition to this, a separate hook member may be forcibly inserted into the space between the first and second screw portions 410 and 420 while forcibly releasing the engagement of the first and second screw portions 410 and 420. These can be applied by borrowing the technology already filed by the applicant.

5 is a schematic cross-sectional view of a string length adjusting device according to a fourth embodiment of the present invention.

If the head 320 is exposed to the outside as shown in FIG. 4, a separate rotation knob 600 may be further inserted into the exposed head 320 region.

As such, according to the present embodiment, there is provided a line length adjusting device which has a simple and simple structure and which can conveniently and effectively adjust the length of the line L.

Although the present invention has been described in detail with reference to the drawings, the scope of the present invention is not limited thereto.

The drawings cited in the above-described embodiments are only shown for convenience of description and the shape of the drawings may not limit the scope of the present invention. Therefore, the position, shape and number of the coupling elements, as well as the thickness or shape of each illustrated component can be appropriately changed.

In addition, in the above-described embodiment, the string has been described as passing through the side portions of the first and second housings in which the skirt portion is not formed.
