In the ratchet 13, two plate-like arm portions 27 are integrally formed on the surface opposite to the teeth 26, and each plate-like arm portion 27 has a hole 29 through which a pin 28 is inserted. There is. A collar portion 30 is integrally formed on the annular inner wall of the base portion 25 so as to project inward.

The top plate 14 has a disk shape, and the top plate 14 has a hole 31 through which the plate-like arm portion 27 is inserted. A tubular portion 32 is integrally formed on one surface of the top plate 14, and an internal thread is formed inside the tubular portion 32. This top plate 1 is separate from this top plate 14
Although the lever 15 is provided on the upper surface of 4, the lever 15 is formed with an insertion hole 33 for inserting the pin 28.

A procedure for assembling the disassembled constituent members shown in FIG. 2 into the states shown in FIGS. 5 and 6 will now be described. First, the reel 12 is put in the annular rib 17 of the base plate 11, and the ratchet 13 is put in the annular reel 12 from above. In this state, the teeth 2 of the reel 12
1 and the teeth 26 of the ratchet 13 come into contact. After that, the spring 34 is housed in the internal space of the ratchet 13, one end of the spring 34 is brought into contact with the collar portion 30 of the ratchet 13, and the other end of the spring 34 is pressed so that the top of the reel 12 or the ratchet 13 is topped. Cover the plate 14. Then, from the lower side of the base plate 11, insert the screw 35 into the through hole 1
9 is inserted, and the screw 35 is screwed into a female screw provided on the tubular portion 32 of the top plate 14, thereby fixing the base plate 11 and the top plate 14. When fixing the base plate 11 and the top plate 14 with the screws 35, the two plate-like arm portions 27 of the ratchet 13 penetrate through the holes 31 of the top plate 14 and project above the top plate 14. Then, the holes 29 of the two plate-like arm portions 27 are aligned with the insertion holes 33 of the lever 15, and the pins 28 are inserted into the holes 29 and the insertion holes 33, and the pins 28 are formed into a plate shape. It is fixed to the arm 27. As a result, the lever 15 is attached to the ratchet 13 so as to be swingable about the pin 28.

As shown in FIG. 6, the ratchet 13 is biased by a spring 34 in a direction away from the top plate 14 (a direction toward the base plate 11). This spring 34 connects the ratchet 13 to the top plate 1
As shown in FIG. 7, in order to urge it away from 4,
No matter which angle the lever 15 swings around the pin 28, the lever 15 always contacts the top plate 14. When the lever 15 swings 90 degrees around the pin 28, for example, the distance from the center point P of the insertion hole 33 of the lever 15 to the contact point (Q and R) of the lever 15 that contacts the top plate 14. To be different. That is,
In FIG. 7, it is assumed that the PQ distance and the PR distance are different (distance PQ <distance PR).

As a result, when the lever 15 is raised in FIG. 7 (when the lever 15 is at the position indicated by the alternate long and short dash line), the pin 28 is relatively separated from the top plate 14 and the base plate 11 and the lever 15 is lowered ( Lever 15
(In the position indicated by the solid line), the pin 28 relatively approaches the top plate 14 and the base plate 11. Lever 1
5 is raised, the ratchet 1 together with the pin 28
3 is raised upward in FIG. 6 (A-A in FIG. 6).
Left of the center line). In this state, the teeth 21 of the reel 12 and the teeth 26 of the ratchet 13 are not meshed with each other, and the reel 12 is set so that it can be freely rotated by hand. In this case, if the reel 12 can freely rotate, the tips of the teeth 21 and the teeth 26 may slightly mesh with each other. On the other hand, when the lever 15 is lowered, the pin 2
8, the ratchet 13 is lowered downward in FIG. 6 (right side of the AA center line in FIG. 6). In this state, the teeth 21 of the reel 12 and the teeth 26 of the ratchet 13 mesh with each other so that the reel 12 can be rotated only in the tightening direction but not in the loosening direction.

Here, the case of wearing shoes will be described.
First, put your foot in the shoe 1 and lower the lever 15 to make the reel 12
The reel 12 is rotated so that the reel can be rotated only in the tightening direction of the string 5. By rotating the reel 12, the string 5 is wound in the outer peripheral groove 22 of the reel 12. That is, in FIG. 1, the laces 5a and 5b are taken into the shoelace tightening tool 4, and the shoelaces are tightened. Even when the reel 12 is released when the desired tightening is reached, the teeth 21 of the reel 12 and the teeth 26 of the ratchet 13 are in close mesh with each other, so the reel 12 does not rotate in the loosening direction, and The string cannot be unraveled. Next, when taking off the shoes, the lever 15 is lifted. This makes reel 1
The meshing between the second tooth 21 and the tooth 26 of the ratchet 13 is disengaged, and the reel 12 is free to rotate. Then, a force for loosening the string 5 that has been tightened acts, and the reel 12 automatically rotates. If the looseness of the lace 5 is small, the lever 15 is pulled up by hand to be automatically pulled out from the shoelace tightening tool 4 and the shoe can be taken off. Even when the reel 12 is rotated too much and the string 5 is tightened too much, the lever 15 is once lifted, and the reel 12 is rotated in the loosening direction to lower the lever 15 at a comfortable position, as in the case of taking off the shoe. Just do it. Also, the lever 1
Instead of 5, it may be a simple ribbon. In this case, when the ribbon-shaped member is pulled upward against the spring 34, the teeth 21 of the reel 12 and the teeth 26 of the ratchet 13 are pulled.
The engagement with and is disengaged, and the string 5 is loosened accordingly.

As described above, according to the shoelace tightening tool of the present invention, the shoelace can be tightened or loosened only by raising and lowering the lever 15 and rotating the reel 12. Therefore, it can be widely applied to sports shoes, such as sports shoes for young children. In addition, most of the components other than the base plate 11 are housed inside the reel 12, and the appearance shape is simple and compact to be compact. Further, since such a compact one is not provided with a return spring, it can be made more compact. Further, when the reel 12 is rotated, the teeth 21 of the reel 12 and the teeth 26 of the ratchet 13 mesh with each other to generate a sound, and the sound causes the consumer to recognize that the string is tightened.
