Conventionally, in order to tighten a shoelace of a boot used for skiing, snowboarding, skating, and the like, the following winding device has been proposed: the shoelace can be wound by rotating a handle (round handle) (patent documents 1 to 5).

In addition, in boots for snowboards and the like, there is a desire to adjust tightening of the instep portion of the shoe main body and the portion of the shoe main body above the gaiter portion by the shoelace, and in order to tighten the shoelace of such 2 systems individually, it is necessary to attach 2 winding devices to the shoe in the winding device described in the above patent document.

Therefore, tightening devices capable of tightening 2 systems of shoelaces with 1 tightening device have been proposed (patent documents 6 to 9).

However, the winding device described in patent document 6 has a problem that the entire device is large in size because the rotation shafts of the 2 winding units are not arranged coaxially.

Further, the winding device described in patent document 7 has a problem that it is difficult to grasp the operating state of the winding device when winding each tape by controlling winding of the tape by pressing the pulley with the handle.

In the tightening devices described in patent documents 8 and 9, the position of the gear formed in the handle itself is changed up and down to drive the gears disposed up and down on the handle, and it is necessary to rotate the handle while paying attention to pressing the handle against the gear.

Further, the winding devices described in patent documents 8 and 9 have the following problems: when the pressing force of the dial is weak, the dial may run idle, and the tightening of the shoelace may not be smoothly adjusted.

", the embodiments and the like described below can be more appropriately embodied.

Moreover, the invention is suitable for realising shoes which: the shoe is provided with the winding device, and different shoelace winding operations can be easily performed by simple operations of changing the rotation direction of the handle.

An embodiment embodying the winding device of the present invention will be described below.

Fig. 1 to 6 are views showing a winding device 10 according to an embodiment of the present invention, and fig. 8 is a view showing a snowboard boot S provided with the winding device 10.

The snowboard boots S have a tongue 2 arranged to close an opening 1 from the inside, as in the case of a general snowboard boot, the opening 1 is formed from the upper surface of the instep portion to the front surface of the neck portion or shin portion, and a winding device 10 is provided on the upper front surface of the tongue 2.

A plurality of pairs of lace guides 3 are fixed to the edges of the opening 1 in an opposed manner, and a plurality of cross guide members 4 for guiding the lace W1 are also fixed to the tongue 2.

The cross guide member 4 can prevent the shoelace W1 from rubbing off each other directly or can prevent the shoelace W1 and the tongue 2 from rubbing against each other to damage the tongue 2.

The string-like 2 laces W1, W2 with thin wires are threaded through the lace guide 3 and the cross guide 4, so that different portions of the snowboard boot S can be individually fastened.

Specifically, the 1 st lace W1 can be tightened around the instep to the ankle of the snowboard boot S, and the 2 nd lace W2 can be tightened around the shin of the snowboard boot S.

Next, the winding apparatus 10 according to an embodiment of the present invention will be described.

The winding device 10 includes: a 1 st lace take-up portion D1 for taking up the 1 st lace W1; and a 2 nd tape winding part D2 for winding the 2 nd shoelace W2.

Specifically, the tape winding portions D1 and D2 are cylindrical rollers or reels each having flanges at both ends.

The 1 st tape winding unit D1 is rotationally driven by the 1 st rotating shaft 11 at the base end portion of the 1 st rotating shaft 11 as indicated by hatching in fig. 1, and the 2 nd tape winding unit D2 is rotationally driven by the 2 nd rotating shaft 12 externally fitted in the vicinity of the center portion of the 1 st rotating shaft 11 as indicated by hatching in fig. 2.

Therefore, the 2 nd rotating shaft 12 is disposed coaxially with the 1 st rotating shaft 11, and the 1 st tape winding unit D1 and the 2 nd tape winding unit D2 are independently driven to rotate by the 1 st rotating shaft 11 and the 2 nd rotating shaft 12.

Further, by switching the rotational direction of the handle 50, which will be described later, of the winding device 10 and performing the rotational operation, the driving force of the handle 50 can be automatically distributed, and the 1 st lace W1 and the 2 nd lace W2 can be individually wound by the 1 st lace winding part D1 and the 2 nd lace winding part D2, respectively.

Further, by operating the release switch 17 provided at the upper portion of the winding device 10, the engagement state of the 2 sets of pawls 18 and the ratchet 19 interlocked with the release switch 17 can be released, and the tightening of the 2 shoelaces W1 and W2 can be simultaneously released.

Here, the state of the release switch 17 and the pawl 18 shown on the left side of fig. 6 is a state in which the shoelaces W1 and W2 can be tightened, and the state of the release switch 17 and the pawl 18 shown on the right side of fig. 6 is a state in which the tightening of the shoelaces W1 and W2 has been released.

The distal end portion (outer end portion) 11a of the 1 st rotating shaft 11 is formed in a hexagonal prism shape on the outer surface, and the 1 st gear member 20 can be coupled and fixed to the distal end portion 11a of the 1 st rotating shaft 11 by fitting the distal end portion 11a into a hexagonal hole 20a through which a cylindrical portion 21 formed at the center of the disk-shaped 1 st gear member 20 passes.

On the inner surface side of the 1 st gear member 20, a 1 st gear G1 is formed in a zigzag shape arranged in a radial pattern on the circumference.

Further, the distal end portion (outer end portion) 12a of the 2 nd rotating shaft 12 is formed into a hexagonal prism-shaped outer surface, and the 2 nd gear member 30 can be coupled and fixed to the distal end portion 12a of the 2 nd rotating shaft 12 by fitting the distal end portion 12a into a hexagonal hole 30a that passes through the center of the disk-shaped 2 nd gear member 30.

A 2 nd gear G2 having a saw-tooth shape and arranged radially on the circumference is formed on the outer surface side of the 2 nd gear member 30.

Here, the 1 st gear G1 and the 2 nd gear G2 are separated from each other, and the direction of the saw teeth is reversed in the assembled state as the winding apparatus 10.

A disk-shaped sliding gear member 40 is disposed between the 1 st gear member 20 and the 2 nd gear member 30, and the sliding gear member 40 includes a 3 rd gear G3 and a 4 th gear G4 which mesh with the 1 st gear G1 and the 2 nd gear G2, respectively.

A circular shaft hole 41 inserted through the center of the sliding gear member 40 is rotatably and slidably loosely inserted into the distal end portion 11a of the 1 st rotating shaft 11.

In this embodiment, the sliding gear member 40 is pivotally supported by the cylindrical portion 21 formed in the center of the 1 st gear member 20.

The 3 rd gear G3 and the 4 th gear G4 of the sliding gear member 40 are formed in opposite directions, so that the 1 st rotating shaft 11 and the 2 nd rotating shaft 12 can be driven to rotate in different directions.

Therefore, when the slide gear member 40 is assembled to the winding apparatus 10, it is not necessary to consider the front-back direction of the slide gear member 40, and the assembling workability is improved.

In addition, the forming positions of the respective saw teeth G of the 3 rd gear G3 and the 4 th gear G4 are set to be different from each other so as to be shifted from each other, so that the thickness of the disc-shaped sliding gear member 40 is made uniform as much as possible, and the strength is not partially lowered.

A total of 4 engaging protrusions 45 are formed on the outer peripheral surface of the slide gear member 40 so as to protrude at positions 90 degrees apart from each other.

In the present embodiment, the engagement projection 45 is formed in a quadrangular shape (having a parallelogram in cross section) having 2 parallel sides contacting side surfaces of the inclined groove 55 described later and 2 parallel sides along the axial direction of the slide gear member 40, and thus the strength and the wear resistance are improved.

The 1 st gear 20, the 2 nd gear member 30, and the sliding gear member 40 are disposed in a bottomed cylindrical gear housing 51, and the gear housing 51 is formed in a handle 50 having a disk-like external shape.

The gear housing 51 has 4 inclined grooves 55 formed on its inner surface along the inner peripheral surface thereof in a spiral manner, and the engagement protrusions 45 are engaged with each other so as to be slidable in the inclined grooves 55.

The inclined groove 55 is formed on the inner surface of the gear housing portion 51 from the opening portion formed on the inner side of the gear housing portion 51 toward the bottom portion, and a lock member 66 is further provided, the lock member 66 restricting a range in which the engagement protrusion 45 disposed in the inclined groove 55 from the opening portion side of the gear housing portion 51 is slidable in the inclined groove 55, and preventing the engagement protrusion 45 from coming off from the inclined groove 55.

In the present embodiment, the lock member 66 is embodied so as to cross the inclined groove 55 in a blocking manner by 4 legs formed to protrude from the back surface of the cover member 60, and the cover member 60 is engaged with the outer surface side of the handle 50 to be integrated with the handle 50.

Further, the distal end portions of the legs are engaged with the hole portions 56 formed on the peripheral edge of the opening portion of the handle 50, so that the state of attachment of the legs (lock members 66) to the inner peripheral surface of the handle 50 is stabilized.

Further, by separating the lock member 66 from the handle 50 as in the present embodiment, the handle 50 can be easily pulled out from the mold by rotating the handle 50 when molding the handle 50.

With the above configuration, as shown in fig. 4, of the height (length) t1 formed in the axial direction of the rotating shafts 11 and 12 of the inclined groove 55, the height (distance) at which the engaging protrusion 45 can move in the inclined groove 55, that is, the distance by which the slide gear member 40 can slidably move is a range (t1-t2) obtained by subtracting the height t2 from the opening of the handle 50 to the position at which the lock member 66 is disposed from the height t 1.

The teeth G of the gears G1 to G4 have the same height, and the sliding gear member 40 and the 1 st gear member 20 or the 2 nd gear member 30 are in close contact with each other so as to have the largest contact area at 2 limit positions when the sliding gear member 40 slides (see fig. 5).

As described above, the arrangement of the gears G1 to G4 enables the sliding gear member 40 to be automatically moved in the axial direction of the 1 st and 2 nd rotating shafts 11 and 12 by a simple operation of changing the rotational direction of the handle 50, and the gears meshing with the gears of the sliding gear member 40 can be switched to either the 1 st gear G1 or the 2 nd gear G2 to be driven to rotate independently.

Therefore, when tightening the 1 st shoelace W1 and the 2 nd shoelace W2, the handle 50 is maintained and rotated in the different forward and reverse directions, so that the 1 st shoelace W1 and the 2 nd shoelace W2 can be tightened continuously and quickly without releasing the hand from the handle 50 and without changing the position of the handle 50 by pushing and pulling the handle 50 again.

Here, the states of the handle 50 and the gears G1 to G4 shown on the left side of fig. 5 represent the following: when the handle 50 is turned leftward, the gear G1 and the gear G3 are engaged with each other, and the 1 st rotation shaft 11 and the 1 st tape winding portion D1 are rotationally driven; the states of the handle 50 and the gears G1 to G4 shown on the right side of fig. 5 show the following: when the handle 50 is turned rightward, the gear G2 and the gear G4 mesh with each other, and the 2 nd rotation shaft 12 and the 2 nd tape winding portion D2 are driven to rotate.

Further, a bolt hole 11b is formed in the tip end portion 11a of the 1 st rotating shaft 11, and a bolt 11c is fixed to the bolt hole 11b, so that the 1 st gear member 20 and the like do not fall off from the 1 st rotating shaft 11 and the 2 nd rotating shaft 12.

The winding apparatus 10 and the snowboard boots S according to the present invention can be easily manufactured by a conventionally known casting technique, a resin molding technique, a sewing technique, and the like, and the winding apparatus 10 can be easily manufactured by arranging and sequentially assembling the respective members as shown in fig. 3 and the like.

The teeth G of the gears G1 to G4 each have a shape in which a triangular prism having a right triangle cross section is arranged in a lateral direction, and one side surface of the teeth that meshes with the other gears is perpendicular to the gear forming surface, and the teeth G are arranged radially at equal intervals around the axial centers of the 1 st gear member 20, the 2 nd gear member 30, and the sliding gear member 40.

In the present embodiment, the gears G1 to G4 are made of a nylon resin containing glass fibers, the 1 st and 2 nd tape winding units D1 and D2 are made of zinc die casting, and the ratchet 18 is made of stainless steel.

The snowboard boot S provided with the winding device 10 configured as described above can adjust the amount of winding of each of the laces W1, W2 individually, and not only can change the tightening state of each of the laces W1, W2 independently, but also can quickly wind 2 laces W1, W2 for tightening different portions of the boot S and tighten the laces W1, W2 without releasing the hand holding the handle 50 of the winding device 10.
