As shown in these figures, the row length adjusting device of this embodiment includes a fixed housing 110, a rotary housing 120, and a coupling unit 130 for coupling the fixed and

rotary housings

110 and 120.

A through hole 111 through which the winding part 122 of the rotary housing 120 passes is formed in the central region of the fixed housing 110. And a fixing flange 112 is formed at the lower end of the fixed housing 110. The fixing flange 112 is used as a part to be fixed when fixing the line length adjusting device according to the present embodiment.

The fixing housing 110 is provided with a line passing hole 115 through which a line (not shown) passes. Although one row through hole 115 is shown in FIG. 1, a pair of row through holes 115 are provided. Of course, the position of the through hole 115 may be different from that of FIG.

In the upper region of the fixed housing 110, first and second toothed shapes machined in different shapes along the thickness direction of the fixed housing 110, that is, the direction in which the fixed and

rotary housings

110 and 120 are coupled to each other ( 113,114 are formed.

The first toothed shape 113 is processed into a shape in which the latch 121 of the rotary housing 120 is rotatable in the forward and reverse directions (clockwise and counterclockwise directions), and the second toothed tooth 114 is the rotary housing 120. Latch 121 is machined into a shape rotatable only in one direction.

The first toothed tooth 113 is positioned above the second toothed tooth 114. When the latch 121 of the rotary housing 120 is disposed and engaged with the first toothed tooth 113, the latch 121 is firstly engaged. Rotation in both forward and reverse directions is possible through the toothed shape 113, but when the latch 121 of the rotary housing 120 is disposed and engaged with the second toothed shape 114, it is rotated only in either the forward or reverse direction. This is made possible by the tooth shapes of the first and second

toothed teeth

113 and 114. With such a structure, the latch 121 can be engaged with the second toothed tooth 114 to wind the string, and the latch 121 is Engagement with the first toothed mold 113 makes it possible to unwind the string.

The rotary housing 120 is a part that is coupled to the fixed housing 110 and is a part that is rotated when the actual device is operated. That is, as the rotary housing 120 is rotated relative to the stationary housing 110, the string is wound (rolled up) or unrolled (unwinded).

The rotary housing 120 is formed with a latch 121 that selectively engages and interacts with the first and second

toothed shapes

113 and 114 described above. The latch 121 has a hook shape in which its free end is elastically movable radially inward or outward.

In the present embodiment, four latches 121 are provided to be spaced apart from each other along the circumferential direction of the rotary housing 120, the number of which does not limit the scope of the present invention.

In addition, the through hole 123 is formed in the rotary housing 120 in which the latch 121 is formed, and the through hole 123 does not necessarily need to be formed in the rotary housing 120. The through hole 123 may be used as a passage for checking the arrangement of the latch 121.

In the rotary housing 120, a winding portion 122 is formed as a portion in which a string is wound. In this embodiment, the winding part 122 has a rod shape integrally formed in the rotary housing 120, and is disposed in a shape accommodated in the above-described through hole 111.

The winding portion 122 is further coupled to the line position maintaining disk portion 124 for maintaining the position of the line while preventing the downward movement of the line. Of course, even if the row position maintaining disk portion 124 is not formed, there is no problem in operation, but if the row position maintaining disk portion 124 is provided, the winding position of the string is due to the row position maintaining disk portion 124. It can be constant, eliminating kinking and obstructions.

The plate surface of the rotary housing 120 is formed with a plurality of rope fixing holes 125 to which the rope is fixed. After the string is fixed by the plurality of string fixing holes 125, the string may be wound around the winding part 122 by rotating the rotary housing 120, and this string fixing hole 125 must also be formed. It is not.

On the other hand, the coupling unit 130, the latch 121 is coupled to the interior of the fixed housing 110 so as to selectively engage and interact with any one of the first and second toothed shape (113,114) radially inward or outward An elastically movable spring 131 and a bolt 133 are coupled to the winding portion 122 to form a body with the winding portion 122, and the latch 121 is engaged with the first toothed shape 113. And a cap 132 disposed in the upper region of the spring 131 (see FIG. 6), and in the lower region of the spring 131 when the latch 121 engages the second toothed 114. .

In this embodiment, the spring 131 may be implemented by wire forming, but the shape does not need to be limited to the shape of FIG. 1.

By this configuration, the fixed and

rotating housings

110 and 120 are coupled using the coupling unit 130.

In this state, the rotary housing 120 is pressed in the direction of the arrow of FIG. 5. Then, the cap 132 constituting the body with the rotary housing 120 is disposed in the lower region of the spring 131 by the operation of the spring 131, the latch 121 is engaged with the second toothed 114. . Since the second toothed tooth 114 is a one-way tooth, when the rotary housing 120 is rotated in one direction in the state as shown in FIG. 5, the string may be wound around the winding part 122, for example, such as a running shoe lace.

On the contrary, if you want to loosen the string such as the shoe laces, pull the rotary housing 120 in the direction of the arrow of FIG. Then, the latch 121 is engaged with the first toothed shape 113 while the cap 132 constituting the body with the rotary housing 120 is disposed in the upper region of the spring 131 by the operation of the spring 131. . Since the first toothed shape 113 is a tooth shape capable of rotating in both the forward and reverse directions, when the rotary housing 120 is rotated in the above-mentioned reverse direction in the state as shown in FIG. 6, the rope wound around the winding part 122 can be released. At this time, there is no phenomenon that the cap 132 is separated by the jaw 116 formed inside the fixed housing 110.
