1 is a perspective view of a string length adjusting device according to a first embodiment of the present invention, FIG. 2 is an exploded view of FIG. 1, and FIGS. 3 and 4 are views showing operation as an assembled view of FIG. 2.

As shown in these drawings, the line length adjusting device 100 of the present embodiment includes a winding unit 110, first and second housings 120 and 130, a handle 140, and an elastic pressing unit 151. And these are assembled.

The winding unit 110 is provided with a rotating shaft 111 constituting a rotating shaft core, a disk portion 112 having a plurality of rotating protrusions 113 formed on a bottom thereof, and extending in a radial direction of the rotating shaft 111, and a disk portion. It is provided with a winding rod 114 is provided to protrude to the opposite side of the rotation shaft 111 in the central region of the 112 and the winding portion 115 is formed on one side of the winding winding.

The rotating shaft 111 is a portion constituting the rotating shaft core of the winding unit 110, is formed to have a small length, and is partially inserted into the shaft insertion portion 121 of the first housing 120. At this time, as shown in Figure 4, even if the handle 140 is raised in the B direction for the unwinding operation of the string, the rotary shaft 111 and the shaft insertion in the line so as not to be completely separated from the shaft insertion portion 121 It will be desirable to determine the size of the portion 121.

The disc part 112 is a part of the central plate of the winding unit 110. It may be common, but not necessarily, to be disc shaped. In other words, the line length adjusting device 100 of the present embodiment may be formed in a circular shape as shown in FIG. 1, but may be changed into a shape such as a square tube or a triangular tube. It can be changed sufficiently.

The winding rod 114 is a part which forms a shaft. In the center of the winding rod 114, a winding portion 115, in which a string is wound, is provided in the form of a hole, and the string may be wound in the winding portion 115 of the hole shape. The upper end of the winding rod 114 may be slightly exposed to the surface of the second housing 130 or may not be exposed.

The first and second housings 120 and 130 are parts forming an appearance, and the first and second housings 120 and 130 may be hooked to each other for convenience of disassembly and assembly. Of course, a threaded coupling method may be applied.

In the central region of the upper surface of the first housing 120, the shaft insertion part 121 is formed to partially insert the rotation shaft 111, and a plurality of the rotation protrusions 113 are selectively accommodated on the outer side of the first housing 120, respectively. A plurality of projection receiving grooves 123 for preventing the rotation of the 110 is formed.

In the present embodiment, the plurality of rotating protrusions 113 and the plurality of rotating protrusions 113 are one type of gear teeth, and have a one-way threaded shape in which rotation in the opposite direction is limited. Therefore, when the handle 140 is rotated in one direction, the winding unit 110 is rotated and the rope is wound around the winding unit 115, even if the rotation stops, and the shapes of the plurality of rotating protrusions 113 and the plurality of rotating protrusions 113. The line wound by the characteristic is not loosened. Gear tooth shape may be various, such as the shape of a square, pentagonal, trapezoidal cross-section, including the triangular threaded teeth shown. Therefore, the drawings are not intended to limit the scope of the present invention.

Of course, in order to be able to implement such an operation, in addition to the shape features of the plurality of rotating protrusions 113 and the plurality of rotating protrusions 113, the winding protrusions 110 may not be randomly separated from the protrusion receiving groove 123. ), The elastic pressing unit 151 for elastically pressing the first housing 120 side should work together.

In this embodiment, the plurality of rotating protrusions 113 and the plurality of rotating protrusions 113 are manufactured to have a one-way threaded shape in which rotation in the opposite direction is limited, but according to the second embodiment of FIG. 5 In the length adjusting device 200, these shapes are manufactured in hemispherical shapes 113a and 123a. However, even if the length adjusting device 200 is manufactured as shown in FIG. However, if it is manufactured to have a one-way threaded tooth shape as in the present embodiment, it will be better to use it where a rather strong fixing force is required, such as sneaker laces. Of course, you may manufacture so that it may have a general screw tooth shape instead of a one-way threaded tooth shape.

The second housing 130 is a portion coupled to the first housing 120 with the winding unit 110 interposed therebetween so that the winding unit 110 is accommodated therein. In the present embodiment, the second housing 130 is formed larger than the first housing 120, but the reverse case is also possible. The through hole 131 is formed at a position corresponding to the winding rod 114 on the surface of the second housing 130.

The handle 140 is a part for rotating the winding unit 110 from the outside of the second housing 130 so that the cord may be wound around the winding part 115. A method of manufacturing the handle 140 integrally with the winding unit 110 may also be considered, but in this case, the assembly may not be easy, and the size of the handle 140 may be reduced, as in the present embodiment. It may be desirable to provide an assembly. Handle 140 may be coupled to the winding rod 114 through the through hole 131 on the outside of the second housing 130, the coupling may be a screw method (141, 116), or press-fit method as shown in the drawing It may be.

On the other hand, the elastic pressing unit 151 is the inner end portion 151a so that the rotary projections 113 are not randomly separated from the projection accommodation groove 123, that is, the cord wound on the winding unit 115 is not unwound randomly. In contact with the winding unit 110 serves to elastically press the winding unit 110 to the first housing 120 side. Of course, when the same as Figure 3, that is, when winding the string, the inner end portion 151a of the elastic pressing portion 151 elastically presses the disc 112, the handle 140 in the direction B of Figure 4 When pulling the elastic portion 151 is opened to the outside as shown in the dotted line of the enlarged portion of Figure 4 the disc portion 112 is located above the inner end portion 151a of the elastic pressing portion 151 112 is substantially separated from the elastic pressing unit 151. Therefore, it is possible to loosen the line in the state as shown in FIG.

In this embodiment, the elastic pressing unit 151 is integrally formed on the side wall of the second housing 130 to elastically press the disc part 112 of the winding unit 110 toward the first housing 120 side. It can be prepared as). Of course, the elastic side wall 151 does not necessarily need to be integral with the second housing 130, and may be provided as a separate type. The elastic pressing unit 151 may be arranged in plural at equal angle intervals along the circumferential direction, and as shown in the figure, a part of the side wall of the second housing 130 is cut off, and the elastic side wall 151 is elastic when molded. What is necessary is just to manufacture in curved shape so that it may have. The more elastic pressing unit 151, the more the force to press the disc portion 112 is helped to secure the string more firmly.

At least one side wall of the first and second housings 120 and 130 has a through-hole 132 through which a line passes. Unlike FIG. 1, a through-hole 132 is not formed, and the elastic side wall 151 is not formed. It is also possible to allow the string to pass through the space.

An operation of the string length adjusting device 100 having such a configuration will be described with reference to FIGS. 2 to 4.

First, in the disassembled state as shown in FIG. 2, the cord is wound into the winding unit 115 while being assembled as shown in FIG. 3. In this state, when the handle 140 exposed to the outside is held and rotated in one direction, for example, in a clockwise direction, the string is wound in the winding unit 115 as shown in FIG. 3. Even if the winding is desired and the handle 140 is released, the elastic pressing unit 151 is elastically pressurized in a direction in which the plurality of rotating protrusions 113 are not separated from the plurality of rotating protrusions 113 so that the line is arbitrarily selected. It is not unwound.

Next, to unwind the string, pull the handle 140 slightly in the B direction as shown in FIG. When the handle 140 is pulled in the direction B of FIG. 4, as shown in the dotted line of the enlarged part of FIG. 4, the elastic pressing unit 151 is opened to the outside, and the disc part 112 has an inner end portion of the elastic pressing unit 151 ( By being positioned above the 151a, the disc part 112 is substantially separated from the elastic pressing part 151 and the plurality of rotating protrusions 113 are separated from the plurality of rotating protrusions 113. As such, when the force applied to the disc part 112 is removed, the entire winding unit 110 including the disc part 112 can be freely rotated, so that the wire was wound by pulling both ends of the wire in the state shown in FIG. 4. It is released. In the case of Figure 4 is merely shown excessively for the convenience of the drawing, the winding unit 110 does not actually need to be up a lot of distance (up).

As described above, according to the present invention, there is an advantage that the length of the string can be easily and effectively adjusted as well as the length and release of the string can be easily and conveniently while having a simple and simple structure.

Particularly, since the present invention is a method in which the string can be unwound only by pulling the handle 140 rather than the applicant's prior art method of pressing the handle 140, the string is unwound. As the handle 140 is inadvertently pressed, it is possible to compensate for the disadvantage of unwinding the line undesirably.

6 is a view of a string length adjusting device according to a third embodiment of the present invention.

Referring to this figure, in the case of the line length adjusting device 300 according to the third embodiment of the present invention, both ends of the elastic pressing unit 152 of one side of the winding rod 114 and the second housing 130 are provided. It is applied by the compression spring 152 which is arrange | positioned at the inner surface, respectively. 6, there is no problem in providing the effect of the present invention. Of course, the first embodiment and the third embodiment may be applied together, but in the case of the present embodiment, unlike the first embodiment, the shape of the winding unit 110a should be slightly changed.

That is, both ends of the compression spring 152 should be disposed on one side of the take-up rod 114 and the inner surface of the second housing 130. For this arrangement, one side of the take-up rod 114 has a spring jaw 114a. On the inner surface of the second housing 130, a spring groove 130a is formed.

However, when the compression spring 152 is used as the elastic pressing unit 152 as shown in FIG. 6, the first and second housings 120 and 130 may be wound up to unwind the cord wound around the winding unit 115. It may be desirable to further provide a take-up release part (not shown) disposed inward to allow the plurality of rotating protrusions 113 to be separated from the plurality of rotating protrusions 113. The take-up release part may be simply provided as a hook type provided in the handle 140 and disposed in the first and second housings 120 and 130 through the through hole 131. Of course, some of the techniques previously filed by the applicant can be used.

7 is a view of a string length adjusting device according to a fourth embodiment of the present invention.

Unlike the above-described embodiment, in the case of the line length adjusting device 400 of the present embodiment, the line drawn through the side surfaces of the first and second housings 120 and 130 is exposed to the outside through the handle 140 region. . In order to apply this structure, the remaining area of the winding portion 115 excluding the hole as the winding portion 115 and the handle 140 communicates with the hole to expose the string to the outside of the second housing 130 ( 170) should be further formed. The application of this structure has the advantage of making the job of unwinding the cord easier.

8 to 11 are diagrams illustrating a string length adjusting device according to a fifth embodiment of the present invention.

In the case of the line length adjusting device 500 of the present embodiment, unlike the above-described embodiments, the handle 240 has a cylindrical shape, and the first tooth 240a is formed on the outer surface thereof. The first tooth 240a has a one-way screw shape and is continuously formed along the thickness direction of the handle 240, but may be a gear shape, or may be partially formed along the thickness direction of the handle 240. .

The cap 160 is detachably coupled to the outer surface of the handle 240. In this case, the inner surface of the cap 160 is formed with a second tooth (160a) is meshed with the first tooth (240a) formed on the outer surface of the handle 240, the position spaced apart from the second tooth (160a) When the cap 160 is pulled together, the locking step 160b is formed on one side of the handle 240 (the bottom in this embodiment) so that the handle 240 can be pulled together with the cap 160. At this time, the interval between the second tooth (160a) and the locking step (160b) in the inner surface of the cap 160 is preferably provided larger than the thickness of the handle 240. Although the second tooth 160a is schematically illustrated in the drawing, it may be regarded as having the same shape as the first tooth 240a of FIG. 8.

In this configuration, the cap 160 is coupled to the handle 240 by pressing in the C direction as shown in FIG. 10 in a separated state as shown in FIG. 9. Then, the second tooth (160a) located in the upper portion of the cap 160 is meshed with the first tooth (240a) formed on the outer surface of the handle 240, the handle is rotated based on the engagement While 240 is also rotated together, as a result, the winding unit 110 can be rotated, thereby winding the string.

On the contrary, to unwind the string, the cap 160 is pulled in the D direction as shown in FIG. 11. Then, at one end, the second tooth 160a positioned above the cap 160 is separated from the first tooth 240a formed on the outer surface of the handle 240. Subsequently, when the cap 160 is pulled in the D direction, the locking jaw 160b located at the lower portion of the cap 160 is caught by the lower end of the handle 240, and in this state, the winding unit 110 including the handle 240 is wound. ) Is up in the D direction. In particular, in the case of Figure 11, the first tooth (240a) and the second tooth (160a) is separated from each other, because the handle 240 can be freely rotated in the cap 160, diarrhea cap ( 160) Even if you grab the string and pull it, the string is easily released. Of course, only a certain amount of the string can be released by only pulling the cap 160 by the elasticity of the wound string. If such a structure is applied, it may be more advantageous to loosen the string.

For reference, in the case of FIGS. 8 to 11, the cap 160 is illustrated in a cylindrical shape. However, since the cap 160 may be cylindrical and only the portion coupled to the handle 240 may be attached, a square bar or a square bar may be added so as to easily grip the cap. The shape of 160 need not be limited to the figures.

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

Although omitted in the above embodiment, the mounting portion may be further provided on one surface of the housing as a means for mounting the cord length adjusting device, for example, shoes or clothes. The mounting portion may be a Velcro, a snap button, or an annular clip.
