These winding devices are capable of tightening shoelaces even while wearing gloves, and are widely used as a highly convenient device especially for snowboard boots.
And, as shoelaces used for these winding devices, wire ropes having a low coefficient of friction are generally used. When the bootlaces are tightened by these winding devices, The portion above the heel of the shoe body is tightened uniformly.

  However, in boots for snowboards, etc., there is a desire to separately adjust the tightening degree of the upper part of the shoe main body and the upper part of the shoe main body by shoelaces, and there are two systems corresponding to each part. Boots equipped with shoelaces and two winding devices corresponding to them have been proposed.

  Accordingly, in a boot using a conventional shoelace winding device, in order to be able to individually tighten different parts of the shoe body, the front part and side part of the shoe body or the rear part and side part of the shoe body, etc. It is necessary to attach a winding device to each, and the structure of the boot becomes complicated and large, the weight of the boot increases, the appearance of the boot is impaired, the manufacturing cost of the boot increases, etc. The problem is inevitable.

Further, in the conventional shoelace winding device, there is a problem that the operation of the winding device becomes complicated in order to individually tighten different portions of the shoe body.
In addition, although the thing provided with the two winding parts of shoelaces in one winding apparatus is proposed (refer FIGS. 28-30 of patent document 3), this winding part is integrated. Since they rotate at the same time, the tightening degree of the two shoelaces cannot be individually adjusted.

Next, the detailed structure of the winding device 20 will be described.
The winding device 20 rotates a rotation driving mechanism X that rotates the first drum D1 for winding the first shoelace W1, and a second drum D2 for winding the second shoelace W2. Rotation drive mechanism Y is provided.
The rotational drive mechanism X and the rotational drive mechanism Y have the components arranged in the reverse direction, and rotate the first drum D1 and the second drum D2 in different directions. The shoelaces W1, W2 are wound up.

  The winding device 20 is connected to a rotary shaft 30 for rotating the first drum D1 that winds up the first shoelace W1 when the handle 21 provided on the front surface of the housing 20a is pulled toward the front side. When the handle 21 is pushed in (see FIG. 1A), the second drum D2 that winds up the second shoelace W2 is connected to the rotary shaft 50 for rotating (see FIG. 1). 1 (B)).

  The rotary shaft 50 is mounted so as to be fitted to the outside of the rotary shaft 30, and both the rotary shafts 30 and 50 have the same rotation center and are selectively rotated by the handle 21. It has become.

  When the first shoelace W1 is wound around the first drum D1, the handle 21 pulled forward as shown by the arrow F in FIG. 1A is rotated counterclockwise in FIG. To do. On the other hand, when winding the second shoelace W2 around the second drum D2, as shown by the arrow R in FIG. 1 (B), the handle 21 pushed backward is rotated clockwise in FIG.

  Therefore, when the first shoelace W1 and the second shoelace W2 are tightened, the wrist is alternately rotated in different forward and reverse directions while holding the handle 21, so that the hand is not released from the handle 21. The first shoelace W1 and the second shoelace W2 can be tightened continuously and quickly.

That is, in the winding device 20 of the present invention, the rotation direction of the handle 21 for tightening the first shoelace W1 and the second shoelace W2 is set to different directions, forward and reverse, so that the wrist is detached from the handle 21. It is possible to omit the operation of separating and rotating the wrist uselessly.
As a result, the winding device 20 of the present invention can be particularly convenient when employed in boots used for skiing, snowboarding, and the like performed while wearing thick gloves.

The handle 21 has a shaft hole 22 at the center, an annular handle gear 23 is formed on the front side of the handle 21 around the shaft hole 22, and an annular handle gear 24 is formed on the rear side. .
A bevel gear 31 as a first gear connected to the rotary shaft 30 is mounted in front of the handle 21, and the bevel gear 31 and the handle gear 23 are pulled in a state where the handle 21 is pulled forward. Can be engaged (see FIGS. 1A, 4 and 5).

On the other hand, behind the handle 21, a bevel gear 51 as a second gear connected to the rotary shaft 50 is disposed, and the bevel gear 51 and the handle gear 51 are pushed in a state where the handle 21 is pushed rearward. 24 can be engaged.
Therefore, switching means for distributing the driving force by the handle 21 to the first drum D1 or the second drum D2 by the handle 21 and the bevel gears 31, 51 according to the forward and reverse rotation directions of the handle 21. Is configured.
The teeth of the handle gears 23 and 24 and the bevel gears 31 and 51 are chamfered at their tips (in this embodiment, R is chamfered about 0.5 mm) and has excellent durability. (See FIG. 6).

The shaft portion 32 of the bevel gear 31 is provided with two rows of front and rear concave grooves 33 and 34 formed in a circular shape, and is inserted through the shaft hole 22 of the handle 21. And the spring 25 arrange | positioned along the axial hole 22 of the said handle | steering-wheel 21 selects the front-and-rear position of the handle | steering-wheel 21 selectively by fitting to the said concave grooves 33 and 34, and either bevel gear 31, 51 can be selectively engaged (see FIG. 4).
Therefore, it is easy to grasp the state of the handle 21 position.

The rotary shafts 30 and 50 are provided with sun gears 35 and 55, respectively, and the sun gears 35 and 55 mesh with the three planetary gears 36 and 56, respectively. The planetary gears 36 and 56 are rotatable while their positions are held by planetary carriers 37 and 57 integrated with the drums D1 and D2. The planetary gear 36 is engaged with an outer gear (not shown) formed on the inner peripheral surface of the annular gear 38.
Similarly, the planetary gear 56 engages with an outer gear 58 a formed on the inner peripheral surface of the annular gear 58.

The drums D1 and D2 (planet carriers 37 and 57) and the rotary shafts 30 and 50 are not fixed to each other, and the annular gears 38 and 58 and the rotary shafts 30 and 50 are not fixed to each other. .
On the other hand, an inner gear (not shown) formed on the inner peripheral surface of the annular gear 38 is engaged with three retaining claws 39a provided at 120 degrees apart from the static friction force control member 39. It has become.
Similarly, on the inner gear 58b formed on the inner peripheral surface of the annular gear 58, three stop claws 59a provided at 120 degrees apart from each other are engaged with the static friction force control member 59. .

  In the state where no great tension is applied to the drums D1 and D2 from the shoelaces W1 and W2, the rotation of the rotary shafts 30 and 50 is performed from the retaining claws 39a and 59a of the static friction force control members 39 and 59 to the annular gears 38 and 59. 58, the drums D1 and D2 are quickly driven to rotate at the same angle as the rotation of the rotary shafts 30 and 50.

  On the other hand, when the shoelaces W1 and W2 are gradually tightened and a large tension is applied from the shoelaces W1 and W2 to the drums D1 and D2, the rotation of the rotary shafts 30 and 50 causes the static friction force control members 39 and 59 to rotate. Can no longer be transmitted to the annular gears 38 and 58, and is transmitted as the rotation of the planetary gears 36 and 56.

Here, gears 38c and 58c with which the lock pieces 40 and 60 are engaged are formed on the outer peripheral surfaces of the annular gears 38 and 58, and the annular gears 38 and 58 as ratchets tighten the shoelaces W1 and W2. It can be controlled so that it only rotates.
Therefore, the rotation of the planetary gears 36 and 56 drives the drums D1 and D2 as rotations obtained by decelerating the rotation of the rotation shafts 30 and 50 (with increased torque).

  As shown in FIG. 8, the ratchet by the lock pieces 40 and 60 is formed by switching the switch 26 attached to the front surface of the casing 20 a of the winding device 20 to the left and right positions. The rotation lock states 38 and 58 can be simultaneously released, and the lock pieces 40 and 60 can be controlled to rotate only in the direction in which the shoelaces W1 and W2 are tightened.

  When the lock piece 40, 60 is driven by the switch 26, a switching shaft 26a fixed to the back surface of the switch 26 is inserted into a long hole 27 formed in the left-right direction at the upper portion of the housing 20a. 26 a is driven along the sliding surfaces 41 and 61 of the lock pieces 40 and 60.

  The shapes of the annular handle gears 23 and 24 formed on the front side and the rear side of the handle 21 and the bevel gears 31 and 51 are as follows: 1) In order to quickly switch the rotation direction of the handle 21, 2) the gears 3) Rotation of the handle 21 so that the gears can be disengaged when the handle 21 is turned in the wrong direction. It is desired that the gear surface be appropriately inclined so as to intersect with a plane orthogonal to the axis.

  Therefore, as shown in FIGS. 9 (A) to 9 (H), the inclination angle of the gear surface of the bevel gear 51 (31) is appropriately changed to change the operability of the handle 21 and the gear (handle gears 23 and 24, bevel gear 31). , 51) Table 1 below shows the results of a comparative study on durability.

From the results of the above comparative study, the inclination angle of the gear surfaces of the handle gears 23 and 24 and the bevel gears 31 and 51 is preferably about 50 to 70 degrees, and the best result is about 60 degrees (57 degrees). Could get.
That is, by tilting the gear surfaces of the handle gears 23 and 24 and the bevel gears 31 and 51 by about 60 degrees (57 degrees), 1) the amount of movement of the handle 2 when switching the handle 21 back and forth is reduced. The switching operation of the handle can be speeded up, 2) the necessary engagement state between the handle gears 23 and 24 and the bevel gears 31 and 51 can be reliably obtained, and 3) the handle 21 is Even when the gears are turned in the wrong direction, the meshing of the gears can be smoothly released.

Next, a method for manufacturing the snowboard boot 10 provided with the shoelace winding device 20 of the present invention will be described.
In order to manufacture the boot 10 provided with the shoelace winding device of the present invention, a sole 11 similar to a normal snowboard boot, and a shoe (having a shoe body upper part 12, a shoe body upper part 13 and an opening part 15). A main body 14 and an inner 16 are provided.

  A second shoelace through hole H2 to a fourth shoelace through hole H4 are formed in the shoe main body 14 along the opening 15 thereof. These shoelace through holes H2 to H4 can be suitably prepared by a conventional manufacturing method in which a shoelace guide that forms a substantially “U” -shaped pipe line that opens to the side is embedded in the shoe body 14. .

Next, the tongue 1 provided with the upper part 3 which comprises the downward part of the bending part 2, and the shin part 4 which comprises the upper part of the bending part 2 is prepared.
And the winding device 20 is fixed to the front surface of the shin portion 4 of the tongue 1, and the upper end portion of the tube 7 having rigidity is connected to the winding device 20 inside the tongue 1. A lower end portion is connected to a first shoelace through hole H1 provided in the tongue 1.
The tongue 1 is attached so as to close the opening 15 from the inside of the shoe main body 14 by sewing the tip 3 a of the tongue 1 manufactured as described above to the shoe main body upper portion 12.

The winding device 20 can be manufactured in advance by arranging the components constituting the rotary drive mechanism X and the rotary drive mechanism Y as shown in FIG.
Then, the shoelaces W1 and W2 are passed through the shoelace holes H1 to H4 and the tube 7 etc., and the first shoelaces W1 are respectively inserted into the shaft portions of the first drum D1 and the second drum D2 of the winding device 20. The both ends of the second shoelace W2 are fixed, and the shoelaces W1, W2 are wound up by the winding device 20 so that the shoelaces W1, W2 can be tightened.

  In this embodiment, the handle gears 23, 24, the bevel gears 31, 51, and the annular gears 38, 58 are manufactured from nylon resin containing glass fiber, and the rotary shafts 30, 50, the planetary carriers 37, 57, the first The second drums D1 and D2, the sun gears 35 and 55, and the planetary gears 36 and 56 are made of an aluminum alloy.

The boot 10 equipped with the shoelace winding device 20 configured as described above adjusts the winding amount of each shoelace W1, W2 individually, and independently tightens the shoelaces W1, W2. In addition to being able to change, two shoes laces W1 and W2 for tightening different parts of the boot 10 can be quickly wound up without releasing the hand holding the handle 21 of the winding device 20 and these shoes The strings W1, W2 can be tightened (see FIG. 10).
Furthermore, the boot 10 can draw the tongue 1 toward the boot wearer's upper part and can always directly and effectively tighten the boot wearer's upper part and the bent part of the ankle. The performance could be demonstrated stably.

  Next, Table 2 below shows the results of tests performed to compare the effect of using the winding device of the present invention with the case of using a winding device having a conventional structure.

  Here, “Test 1” in Table 2 indicates the angle at which the handle turns when one shoelace is wound by the variable speed winding device employing the planetary gear mechanism disclosed in Patent Document 2. This is a measurement of the winding amount of the string, the number of times the handle is wound up to the end of tightening the shoelace, and the total time from the start of winding to the end of winding.

  Similarly, “Test 2” in Table 2 is a handle in the case where one shoelace is wound up by a conventional shoelace winding device that does not have a speed change mechanism as disclosed in Patent Document 1 and the like. The angle at which the shoe turns, the winding amount of the shoelace, the number of times the handle is wound, and the total winding time are measured.

  Similarly, “Test 3” in Table 2 indicates that two shoelaces are formed by a boot equipped with two conventional shoelace winding devices that are not equipped with a speed change mechanism as disclosed in Patent Document 1 and the like. The angle at which the handle turns, the amount of shoelace wound, the number of times the handle is wound, and the total winding time are measured.

  Similarly, “Test 4” in Table 2 shows the angle at which the handle turns when the shoelace winding device 20 embodies the present invention winds up two shoelaces, the amount of shoelace winding, , And the total time of winding.

Therefore, it was confirmed that the present invention can rapidly wind up two shoelaces as compared with a conventional shoelace winding device.
That is, by using one winding device of the present invention, even if two shoelaces are used, the two shoelaces are wound up and tightened in approximately the same time as when one shoelace is wound up. I was able to.

  The present invention is not limited to the above-described embodiment, and by operating the handle 81 that employs a ratchet mechanism as shown in FIG. It may be embodied as a winding device 80 capable of rapidly winding two pairs of shoelaces by alternately rotating them alternately.

That is, in the winding device 80 of the second embodiment, when the gears 82 and 83 are connected to the rotary shaft 30 and the rotary shaft 50, respectively, and the handle 81 is rotated forward, only the rotary shaft 30 is used. The present invention can be embodied by enabling rotation and allowing only the rotation shaft 50 to rotate when the handle 81 is reversely rotated.
Unlike the winding device 20 of the first embodiment, the winding device 80 does not need to manually switch the position of the handle 81 back and forth, so that the operation of winding the shoelace becomes easy. There is a risk that the mechanism for unlocking is slightly complicated.

  In this specification, the shape of the handle is not particularly limited as long as it functions as an operation unit for rotationally driving the rotation drive mechanisms X and Y, and a disc-shaped or polygonal dial is used. In addition, a tab, a trident, a cross, a star or the like may be used.

In the present invention, it is sufficient that the two winding portions can be alternately driven by reversing the rotation direction of the handle, and the rotation directions of the two winding portions may be the same or opposite directions. Good.
However, as in this embodiment, the configuration of the rotary drive mechanism X is the same as the configuration of the rotary drive mechanism Y by setting the winding directions of the shoelaces W1 and W2 by the two winding portions to different forward and reverse rotational directions. It can be as simple as turning it back and forth.
Further, it is optional to roll up the first shoelace or the second shoelace with the rotation direction of the handle as the normal rotation.

  In the embodiment of the present invention, the first and second drums D1 and D2 are arranged on the same axis, and the rotary drive mechanism X and the rotary drive mechanism Y are arranged in the front and rear. For example, the first drum D1 and the second drum D2 may be arranged on different axes, and for example, the rotation drive mechanism X and the rotation drive mechanism Y may be arranged on the same plane.

  The present invention is not limited to a winding device for tightening wired shoelaces as in the above embodiments, but a winding device for winding two shoelaces that tighten different portions of the shoe body upper 12. The present invention may be embodied in a specific manner, or may be embodied in a winding device that winds up two pairs of shoelaces that fasten different portions of the shoe body upper portion 13.

In addition, as a result of repeating the test, the operation method of this embodiment is easy to handle by pushing the handle, rotating the handle in the clockwise direction, pulling the handle, rotating the handle in the counterclockwise direction, and tightening the shoelace. I understood that.
When the winding device is installed on the upper part of the shoe main body, it goes without saying that the handle switching operation by the winding device 20 is not in the front-rear direction but in the vertical direction.

The present invention is not limited to the above embodiments, and may be implemented using the shoelace winding device of the present invention for boots used for skiing, skating, mountain climbing, riding a motorcycle, and the like.
Furthermore, the material, shape, dimensions, strength, installation position, thickness, size, number, and the like of each part of the winding device may be appropriately changed without departing from the spirit of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used as a shoelace winding device for boots used for skiing, snowboarding, skating, mountain climbing, motorcycle riding, and the like.
