For example, when the user or assistant turns the button dial 1340 in one direction (eg, clockwise), the wire winding 1342 coupled to the button dial 1340 also turns in one direction. As a result, the wire 1350 may be wound while the leaf spring 1339 provided in the wire winding part 1341 is contracted (ie, compressed).

Of course, if the user or assistant turns the button dial 1340 in a direction opposite to one direction (for example, counterclockwise), the wire winding 1342 coupled to the button dial 1340 is also in the opposite direction. As a result, the wire 1350 may be unwound while the leaf spring 1335 provided in the wire winding part 1341 is expanded (that is, restored).

Here, as shown in FIG. 13, the wire winding part 1341 has a wire insertion hole 1341a into which a wire 1350 is inserted, and at the center thereof, a movement of the button-type dial 1340 (ie, A protrusion 1341b selectively connected to the button-type dial 1340 may be provided according to the withdrawal.

That is, when the button dial 1340 is connected to the protrusion 1341b, the wire winding 1342 rotates by the rotation of the button dial 1340, and the button dial 1340 is separated from the protrusion 1341b ( That is, in the case of separation, the wire winding part 1341 may be rotatable without being restricted by the button-type dial 1340.

In addition, when the user or the assistant pulls the button-type dial 1340 downward or upward, the latch hook 1335 may be fastened or detached from the latch ring 1237. For reference, the button-type dial 1340 may be withdrawn step by step (that is, step 1 withdrawal and step 2 withdrawal (steps withdrawn upward than step 1)).

As such, the sub-frame unit 5 of the muscle strength assisting apparatus 1 according to the embodiment of the present invention may have the above-described features and configurations.

Hereinafter, referring to FIGS. 14 to 24, a method of adjusting the belt 1250 according to withdrawal or rotation of the aforementioned button-type dial 1340 will be described in more detail.

14 to 24 are schematic views for explaining a belt adjusting method according to withdrawal or rotation of the button-type dial of FIG.

First, referring to FIGS. 13 to 16, the button-type dial 1340 is pulled out one step upward (that is, in the 'UL' direction) (ie, the upper end of the button-type dial 1340 moves from the R2 line to the R3 line). ), The protrusion 1341b is separated from the button-type dial 1340, and the wire winding 1341 is rotatable without being restricted by the button-type dial 1340. Accordingly, the user detaches and pulls the belt coupling part 1230 from the end of the first sub waist support part 1200 in the 'B' direction to fix his waist, and then inserts the second sub waist support part 1300. It can be inserted into the hole 1332. Of course, even in this case, the tension of the leaf spring 1339 may act on the belt 1250 via the wire 1350.

That is, when the belt coupling part 1230 is detached from the end of the first sub waist support part 1200 and inserted into the insertion hole 1332 to fix the waist of the user, the belt coupled to the belt coupling part 1230 ( 1250 is drawn out of the first sub waist support 1200 through the belt withdrawal hole 1232, and the belt coupling part 1230 is inside the distal end of the second sub waist support 1300 through the insertion hole 1332. It may be coupled to the wire winding structure 1330 installed in.

More specifically, the belt coupling plate 1236 is coupled to the belt coupling member 1336 through the insertion hole 1332, the latch hook 1237 of the belt coupling plate 1236 is a latch hook of the belt coupling member 1336 (1337) can be fastened.

In summary, when the user pulls out the button-type dial 1340 one step upward (that is, in the 'UL' direction), the connection between the button-type dial 1340 and the wire winding part 1341 is released. Accordingly, the user can pull the belt coupling portion 1230, and when the pulled belt coupling portion 1230 is inserted into the insertion hole 1332, the belt coupling member 1336 is moved by the belt coupling plate 1236. The latch hook 1337 may be fastened to the latch ring 1237 while being tilted.

Through this, the user can easily fix his waist to the muscle strength assistance device (1).

Subsequently, referring to FIGS. 13 and 17 to 19, the button-type dial 1340 is pulled downward (ie, 'L' direction) with the belt engaging plate 1236 coupled to the belt engaging member 1336. (I.e., when the top of the button-type dial 1340 moves from the R3 line to the R2 line) and then rotates in the winding direction of the wire 1350 (ie, the 'WD' direction), it is within the tension range of the belt 1250. Wire 1350 may be wound into the leaf spring 1339 (ie, wound in the 'UB' direction).

That is, when the user pulls the button-type dial 1340 downward (that is, 'L' direction), the button-type dial 1340 and the wire winding part 1338 (that is, the protrusion 1341b) may be connected. In addition, when the user rotates the button dial 1340 in the winding direction (ie, 'WD' direction) of the wire 1350 in a state in which the button dial 1340 and the wire winding part 1341 are connected, the wire 1350. ) Can be tightened more tightly as the leaf spring 1339 is wound.

On the other hand, referring to Figs. 13, 20 and 21, the button-type dial 1340 is pulled back one step upward (i.e., in the 'UL' direction) (i.e., the top of the button-type dial 1340 is the R2 line. Is moved to the R3 line), the protrusion 1341b is again separated from the button-type dial 1340, and the wire winding 1134 is again rotatable without being constrained by the button-type dial 1340. In addition, the tension force of the leaf spring 1339 acts on the belt 1250 through the wire 1350, and the belt 1250 tries to be wound back into the guide passage (for example, 1205, 1105, etc.).

However, the fastening state between the latch hook 1237 of the belt coupling plate 1236 and the latch hook 1335 of the belt coupling member 1336 is maintained as it is, and thus, the belt coupling plate 1236 is also a belt coupling member 1336. ), The belt 1250 may not be wound into the guide passage (eg, 1205, 1105, etc.).

In summary, when the user pulls the button-type dial 1340 back upward (that is, in the 'UL' direction) to release the belt 1250, the button-type dial 1340 and the wire winding part 1341 While the connection is released, the restriction of the leaf spring 1339 provided in the wire winding part 1341 is released. However, due to the fastening state between the latch ring 1237 and the latch hook 1357, the belt 1250 is a guide passage (e.g., For example, 1205, 1105, etc.).

Finally, referring to FIGS. 13 and 22 to 24, the button-type dial 1340 is moved upward (ie, 'UL' direction) with the belt engaging plate 1236 coupled to the belt engaging member 1336. When the two-stage withdrawal is performed, the latch hook 1335 of the belt coupling member 1336 may be detached from the latch ring 1237 of the belt coupling plate 1236, and the wire 1350 may be wound up again by the plate spring 1335. .

That is, when the user pulls the button-type dial 1340 up two steps (ie, 'UL' direction) (ie, the upper end of the button-type dial 1340 moves from the R3 line to the R4 line), the belt engaging member The latch hook 1335 is disengaged from the latch hook 1237 while the shaft 1342 for fixing the 1336 is interlocked with the button-type dial 1340 and pulled upward (ie, 'UL' direction). In addition, as the latch hook 1335 is separated from the latch ring 1237, the belt coupling part 1230 is also detached from the insertion hole 1332, and is unloaded by the restoring force of the leaf spring 1335 provided in the wire winding part 1321. Wire 1350, which was once again, may be automatically wound (ie, moved in the 'UB' direction) to the leaf spring 1339. For reference, the bottom surface of the wire winding structure 1330 (ie, the wire winding body 1338) may also be moved upward in the R5 line along with the axis 1342.

Through this, the user can easily loosen the belt 1250. In addition, the belt 1250 is automatically wound and stored in the sub-frame unit 5, so that the user or assistant may prepare for the next wearing without additional cleanup.
