One, inner boots 1

3 and 4, the inner boot 1 will be described in detail. It should be pointed out that the following description is only for one of the inner boots 1 (left boot), but it should be understood that the other (right boot) is a mirror image relationship with the described one, and will not be repeated here. .

Boot 1 is a high-top design, including sole part 101, toe part 102, upper part 103, tongue 104 and shoelace 105, upper part 103 includes inner upper part 103L and outer upper part 103M, inner upper part 103L and outer upper part The part 103M is connected at the heel position and is optionally covered with a heel strip (not shown). Each upper part includes a front part 1031 and a rear part 1032. It should be understood that this division of the upper part is only For the convenience of description, the front upper part 1031 is the part of the upper part that roughly covers the foot, and the rear upper part 1032 is the upper part covering the part of the calf upward from the ankle. The tongue 104 is disposed between the outer upper part 103M and the inner upper part 103L and inside the upper part, thereby overlapping the front upper part 1031 and the rear upper part 1032.

The opposite part of the inner upper part and the outer upper part constitutes a shoelace area. In the shoelace area, a plurality of shoelace hooks 106 and 107 are fixed on the upper part, and the shoelace 105 bypasses these

hooks

106 and 107 to fasten the boot 1.

Specifically, referring to FIG. 3, in the shoelace area of the front upper part 1031, a plurality of (two in the figure) first shoelace hooks 106 are fixed, and the first first shoelace hook 106 of the outer front part 1031M is fixed. A lace hook 106 is aligned with the initial first lace hook 106 of the inner front upper portion 1031L, but the second first lace hook 106 of the outer front upper portion 1031M is aligned with the second first lace hook 106 of the inner front portion 1031L The first shoelace hook 106 is staggered. In the rear part, the second lace hook 107 in the outer rear part 1032M and the second lace hook 107 in the inner rear part 1032L are staggered from each other, and are also opposite to the last first shoe of the opposite front part. The belt hooks are staggered.

The first shoelace hook 106 fixed on the front upper part has a U-shaped cross section (cross-section taken perpendicular to the surface of the front upper part), the shoelace 105 is hung in the U-shaped groove, and the U-shaped groove bottom is formed The arc-shaped profile facilitates the two-way sliding of the shoelace. The second shoelace hook 107 fixed on the rear upper part similarly has a U-shaped cross section (cross-section taken perpendicular to the surface of the rear upper part), and the shoelace 105 is hung in the U-shaped groove. The groove bottom or the two opposite inner sides are formed with inverted triangular protrusions or barbs (not shown), so that the shoelace 105 can only be pulled in the tightening direction, while preventing the shoelace 105 from moving in the opposite direction slide.

As shown in Figure 3, the shoelace 105 starts from the first shoelace hook 106 at the beginning of the inner front upper part 1031L or the outer front upper part 1031M, alternately bypasses the shoelace hooks of the opposing upper part, and in the shoelace 105 An engaging device such as Velcro 108 (Velcro) is fixed at the end, and a matching buckle tape (engaging element, not shown) is fixed near the position of the upper part near the shoe mouth. The buckle at the end of the shoelace The strap 108 can be glued to the mating buckle strap, thereby fixing the end of the shoelace. However, other forms of Velcro or hooks can also be used, and the present invention is not limited to Velcro. The starting end of the shoelace 105 extends upward from the first shoelace hook 106 starting from the shoelace 105, and is fixed to the last first shoelace hook 106 of the inner front upper part 1031L and the last first shoelace hook 106 of the outer front upper part 1031M. A fixing part 109 is formed on a part of the shoelace extending between the shoelace hooks 106. The fixing portion 109 can be formed in various ways, for example, a knot in the shoelace, or a metal lock ring is used to press the starting end of the shoelace onto the shoelace part. By fixing the starting end of the shoelace 105 at the fixing part 109, when the shoelace is tightened, the starting end of the shoelace is fixed at the fixing part 109, so that it is pulled on the front part from two directions at the same time. The shoelace is helpful to fasten the front upper part. In addition, the fixing part 109 can only move between the second shoelace hook 106 of the inner front upper part 1031L and the outer front upper part 1031M, and cannot cross the shoelace hook 106, thereby limiting the distance that the shoelace 105 can be pulled. At the same time, when the shoelace 105 is loosened, the fixing portion 109 also cannot cross the last first shoelace hook 106 of the other side of the front upper part, as shown in FIG. 4, so as to prevent the shoelace 105 from being loosened too much. Disengage from the shoelace hook. It should be understood that although the fixing portion 109 is shown between the second shoelace hooks in FIG. 3, the fixing portion 109 may also be formed on other sections of the shoelace. Since the fixing portion 109 is formed, it is pulled When lacing the shoelace, the shoelace part of the front upper part can be simultaneously pulled from two directions, thereby facilitating the tightening of the shoelace of the front upper part.

As shown in FIGS. 3 and 4, in the state shown in FIG. 4, the skier can easily insert the foot into the boot 1, and the shoelace will not be detached from the first shoelace hook 106 but held on the shoelace. On the hook 106, the skier can use one hand to hang the shoelace on the second shoelace hook 107 and pull the shoelace 105. Because the shoelace hook 107 has an inverted triangular protrusion or barb, it prevents it from being tightened. The shoelace 105 is loosened, and there is no need to hold the shoelace with the hand. Even if the hand is temporarily loosened, it will not cause the shoelace to loosen. Therefore, the shoelace 105 can be easily tightened to a predetermined level even with only one hand.

Hereinafter, the sole 2 of the boot 1 according to the present invention will be described with reference to FIGS. 5 and 6. The sole 201 can be fixed to the upper part in any known manner, and play a supporting role. The bottom surface of the sole 201, that is, the surface in contact with the bottom surface has a non-slip pattern. For ease of description, the sole 201 is divided into a toe area 210, a forefoot area 220, a middle area 230, and a heel area 240.

The toe area 210 includes a plurality of concentric protrusions 211, and these concentric protrusions 211 may have a triangular cross-section to provide the boot 1 with anti-slip properties. In addition, in the forefoot area 220, a plurality of

annular protrusions

221 and 222 are provided. The annular protrusions include large annular protrusions 221 arranged in three rows of four, four and two, and a plurality of annular protrusions arranged in the middle of the three rows of large annular protrusions 221. Small annular protrusions 222, these annular protrusions have a relatively thin wall thickness, so that when the boot 1 steps on the ice, the

annular protrusions

221 and 222 are deformed like suction cups, and the sole of the boot 1 is adsorbed on the ice. It plays a role in preventing ice and sliding. In the heel area 240, similarly includes a plurality of annular protrusions 241, shown as four in the figure, arranged in a diamond shape, the function of these annular protrusions 241 is similar to that of the

annular protrusions

221 and 222 in the forefoot area 220 effect. By forming annular protrusions in the forefoot area and the heel area that support the feet of the skier, the skier wearing the boots 1 can have good adhesion even when walking on the ice surface and prevent slipping.

In addition to the above-mentioned annular protrusions, a plurality of grooves 250 are formed on the bottom surface of the sole. These grooves 250 can play a role in drainage and snow drainage. As can be seen from the cross-sectional view, the grooves 250 have a trapezoidal shape and face the bottom. The opening gradually expands, and the middle trapezoid bottom forms a rounded corner, thereby preventing snow from accumulating in the grooves 250, or the grooves 250 may also have an arc-shaped cross section to prevent snow from accumulating in the grooves.

In addition, in order to improve comfort, cavities 260 are formed in the sole, and these cavities can be filled with high-pressure gas to form an air cushion.

2. Outer boots 3

Hereinafter, the outer shoe 3 according to the present disclosure will be described with reference to FIGS. 7A to 10B. The outer boots 3 are made of harder materials to meet the needs of controlling the snowboard during skiing. The material is, for example, TPU (thermoplastic polyurethane elastomer rubber), PVC, PE, PP, etc., among which TPU is a preferred material due to its excellent low temperature performance.

As shown in FIGS. 7A and 7B, the outer boot 3 includes a sole 31, an upper 32, a tongue 33, and a shaft 34, wherein the upper 32 includes a toe portion 321, a middle portion 322, and a heel portion 323. More specifically, the toe portion 321 further includes a lateral toe portion 321L and a medial side toe portion 321M, the middle portion 322 includes a lateral middle portion 322L and a medial middle portion 322M, and a heel portion 323 Including the outer heel part 323L and the inner heel part 323M. The boot 34 includes an inner boot portion 34M and an outer boot portion 34L.

The tongue 33 is hinged to the rear end of the toe portion 321, so that the tongue 33 can pivot forward so that the outer boot 3 is in one of the open configurations. In this configuration, the inner shoe 1 can be easily inserted into the outer shoe 3 or taken out of the outer shoe 3. After the inner boot 1 is inserted into the outer boot 3 or after the inner boot 1 is removed from the outer boot 3, the tongue 33 can be pivoted back to the closed position (as shown in FIGS. 8A and 8B), whereby the outer boot 3 Place in closed configuration. In order to maintain the closed head shape of the outer shoe 3, a closing and tightening and locking assembly 35 is provided on the upper part of the outer boot barrel portion 34L. The closing and tightening and locking assembly 35 includes a locking wire 351, a hook 352, and a tightening and locking assembly. 353 (described in detail below), thereby locking the tongue 33 in the closed position (as shown in FIGS. 8A and 8B).

Therefore, when the tongue 33 needs to be opened to place the outer boot 3 in the open configuration, the tightening lock 353 can be released and the locking wire 351 can be removed from the hook 352, thereby the tongue 33 can be opened. In one embodiment, a biasing device (not shown), such as a torsion spring, may be provided at the connection of the tongue 33 and the toe portion 321 to bias the tongue 33 to the open position. After the inner shoe 1 is inserted, the locking wire 351 is hung on the hook 352 again and the locking wire 351 is tightened by the tightening lock 353, so that the outer shoe 3 is in a closed configuration (as shown in Figures 8A and 8B) Show).

The outer boot 3 is also provided with a hardness adjustment component, which can adjust the hardness of the outer boot 3 according to the needs of the user (skier), so that the user can better control the snowboard.

The stiffness adjustment assembly 36 includes an opening groove 361 formed near the junction between the rear portion of the upper 32 and the boot barrel 34. The opening groove 361 extends from the rear end of the heel portion 323 all the way forward and slightly upward to approximately the boot Half of the size of the barrel 34 in the front-rear direction is provided with the opening groove 361 to impart a certain elasticity between the boot barrel 34 and the upper 32. The hardness adjustment assembly 36 also includes an adjustment wire 362 and an adjuster 363 for adjusting the tension of the adjustment wire 362 (described in detail below).

The adjustment line 362 starts from the toe part 321, extends on the inner side and the outer side of the upper 32, and extends upward across the opening groove 361 at the heel part 323, and reaches the adjuster 363. The user can change the tension of the adjusting wire 362 by rotating the adjuster 363, thereby changing the elasticity between the boot barrel 34 and the upper 32, and thus the hardness of the entire outer boot.

In one embodiment, a wire tube (not shown) is provided on the upper 32, and the adjustment wire 362 extends inside the wire tube, so as to prevent the adjustment wire 362 from being hung on other objects or entangled or knotted by itself.

Hereinafter, another embodiment of the outer shoe will be described with reference to FIGS. 9A to 10D. In the embodiment of FIGS. 9A to 10B, the same parts as the outer boots described in FIGS. 7A to 8B bear the same reference numerals, and will not be repeated.

The tooth cover 46 is evenly provided with a plurality of penetrating openings around the circumferential direction, and each of the openings 4610 is provided with a pawl 462 (three in the figure), and the pawl 462 extends to the side of the tooth cover 46 facing the spool 43 , And can swing around the root of the pawl 462 in the opening 4610, and a spring 463 is also provided. The spring pierces a plurality of pawls 462 (three in the figure) together and moves the pawls 462 radially outward Bias, so that when the tooth cover 46 is installed in the box body 42, the pawl 462 can engage with the ratchet teeth 422 on the inner periphery of the opening edge of the box body 42 so that the tooth cover 46 can only rotate in one direction, and Therefore, the engagement of the teeth of the gear cover 46 with the groove 431 of the spool 43 drives the spool 43 to rotate in only one direction, for example, the direction in which the locking wire 351 is wound on the spool 43, that is, the first Direction or winding direction.

The other end surface of the tooth cover 46, that is, the end surface opposite to the end surface on which the teeth are provided, is provided with a recessed portion 464. The recessed portion 464 is approximately oblong. Protruding pillars 465 are provided in the vicinity of the part. An oblong locking member 47 is arranged in the recessed portion 464, and two long-direction ends are sleeved on the protruding column 465. The locking member 47 is made of, for example, a wire spring.

The main shaft 423 is a hollow shaft, the long bolt 41 passes through the boot tube from the inner surface of the boot tube and through the hollow main shaft 423, and the lock nut 48 is tightened on the threaded end of the long bolt 41. The lock nut 48 includes two parts, namely, a small diameter part 481 and a large diameter part 482. When the lock nut 48 is tightened, the lock piece 47 is clamped on the shoulder between the small diameter portion 481 and the large diameter portion 482, thereby assembling the tooth cover 46 and the spool 43 in the wire box 42.

The knob 49 is buckled on the tooth cover 46 (see FIG. 13), and the knob 49 is connected with the tooth cover 46, so that the knob 49 can be rotated at a certain angle relative to the tooth cover 46 in the circumferential direction, but together with the tooth cover in the axial direction mobile. In order to connect the knob 49 with the tooth cover 46, a plurality of bosses 491 are provided on the inner periphery of the opening edge of the knob 49. The bosses 491 can slide in along the L-shaped guide grooves 467 provided on the outer circumference of the tooth cover 46, and When the boss 491 of the knob 49 continues to rotate along the L-shaped guide groove 467, the boss 491 can slide into the slit 461. At this time, the elastic piece 468 arranged in the L-shaped guide groove 467 bounces to prevent the boss 491 Exit from the L-shaped guide groove 467. By means of the engagement between the boss of the knob 49 and the slit 461, the knob 49 can be rotated relative to the gear cover 46 at a limited angle, but can move along the axial direction together with the gear cover 46. On the edge of the opening of the knob 49 on the circumferential rear side of the boss 491, a recess 493 can be provided, so that after the knob 49 is installed on the gear cover 46, the recess 493 exposes a part of the elastic sheet 468, by using a tool ( For example, a screwdriver passes through the recess 493 to press down the elastic sheet 468, and the boss 491 of the knob 49 can be retracted into the L-shaped guide groove 467 and withdrawn from the guide groove 467, thereby removing the knob 49 from the tooth cover 46 Take it down.

The knob 49 is provided with a shift fork 492 on the end face opposite to the tooth cover 46. The shift fork 492 is inserted into the oblong locking member 47, and as the knob 49 rotates relative to the tooth cover 46, the shift fork will lock the locking member. 47 is expanded so that the size of the opening of the locking member 47 exceeds the diameter of the large-diameter portion 482 of the locking nut 48, so that the tooth cover 46 can move outwardly away from the spool 43 along the locking nut 48. In order to prevent the tooth cover 46 from disengaging from the lock nut 48, the diameter of the central hole 466 of the tooth cover 46 may be smaller than the diameter of the large diameter portion 482, so that the moving range of the tooth cover 46 is restricted by the central hole 466 of the tooth cover 46 It cannot be disengaged from the lock nut 48. In order to increase the moving distance of the gear cover 46, a large-diameter counterbore (not shown in the figure) may be formed on the outer periphery of the central hole 466, so that the large-diameter portion 482 of the lock nut 48 can be moved into the large-diameter counterbore.

When the knob 49 is rotated and the knob 49 is pulled outward to drive the tooth cover 46 to move outward, the teeth on the tooth cover 46 are disengaged from the groove 431 of the spool 43, and thus the rotation of the spool 43 is no longer restricted. At this time, the locking wire 351 can be unfolded from the spool 43 and pulled out from the tightening locker. When the locking wire 351 is released, the spool 43 naturally rewinds due to the restoring force of the clockwork spring 44, and the locking wire 351 is wound back to the spool to prevent the locking wire 351 from staying outside the tightening locker and hanging Tangle or knot on other objects or on itself.

The following briefly describes the operation process of closing and tightening the locker 353:

After inserting the inner boot 1 into the outer boot 3, the user (skier) hangs the locking wire 351 on the hook 352 and turns the knob 49, which drives the tooth cover 46 to rotate in the first direction (winding direction ), at this time, the teeth 469 on the end surface of the tooth cover 46 are embedded in the groove 431 of the spool 43, thereby driving the spool 43 to rotate in the first direction (winding direction), thereby winding the locking wire 351 on the spool 43 on.

When the knob 49 is rotated, the tooth cover 46 is in a state where the locking member 47 is clamped on the shoulder between the small diameter part 481 and the large diameter part 482 of the lock nut 48. The pawl 462 of the tooth cover 46 and the line The ratchet teeth 422 of the box 42 are engaged, thereby allowing the tooth cover 46 to rotate in the first direction, that is, the winding direction, thereby allowing the spool 43 to wind the locking wire 351 tightly. However, due to the one-way engagement between the pawl 462 and the ratchet teeth 422, the ratchet teeth 422 of the wire box 42 prevent the tooth cover 46 from rotating in the opposite direction (the second direction or the loosening direction), whereby the tooth cover 46 passes The teeth on the end face are embedded in the groove 431 of the spool 43 to prevent the spool 43 from rotating in the second direction or the direction of loosening the locking wire 351. Through this unidirectional winding action, the locking wire 351 is tightened, In turn, the outer shoe 3 is maintained in the closed configuration.

When it is necessary to place the outer shoe 3 in the open configuration, turn the knob 49 in the opposite direction. First, the boss 491 rotates in the slit 461. At this time, the boss 491 has not yet abutted on the elastic sheet 468. The gear cover 46 is not driven to rotate. During this period of rotation, the fork 492 of the knob 49 stretches the locking member 47 so that the opening of the locking member 47 is larger than the diameter of the large-diameter portion 482, and then the knob 49 is pulled so that the tooth cover 46 and the knob 49 follow together The lock nut 48 moves outward, so that the teeth on the end surface of the tooth cover 46 escape from the groove 431 of the spool 43, so that the spool 43 is released. In this case, since the spring force of the spring 44 is small, the user (skier) can easily pull the locking wire 351 out of the tightening locker 353 and remove it from the hook 352, so that the outer boot 3 can be placed in an open configuration. After the user loosens the locking wire, with the help of the spring 44, the locking wire is automatically collected into the wire box 42 of the tightening lock 353 to prevent the locking wire 351 from staying outside the wire box 42 and hanging Tangle or knot on other objects or on itself.

Four, hardness adjustment components

As mentioned above, the hardness of the outer boots 3 can be freely adjusted according to the needs of the user (skier). This is because in snowboarding, the skier needs to control the snowboard through the ski boots to achieve various skiing actions. Unlike skis that control the skis by tilting the skier's body left and right, snowboarding needs to control the snowboard by the forward and backward pitching of the skier's body, which requires a higher hardness of the joint position of the boot tube and the upper of the ski boot. , And the more skilled the skier, the greater the hardness required. Therefore, by adjusting the hardness of the outer boots 3, the skier can better perform its abilities and complete various skills and actions.

The hardness adjustment component includes an opening groove 361 disposed near the junction of the upper 32 and the boot barrel 34, an adjustment wire 362 wired on the surface of the upper 32 and the boot barrel 34, and a hardness adjuster 363 that adjusts the tension of the adjustment wire 362 . Thus, the user can adjust the tension of the adjustment wire 361 by turning the knob 58 of the hardness adjuster 363, thereby adjusting the hardness of the entire upper and the boot shaft, that is, the hardness of the ski boot, so as to achieve a satisfactory level of hardness.

The structure of the hardness adjuster 363 is similar to the structure of the tightening locker 353, which is described below with reference to FIG. 12, in which for convenience and brevity, only the difference between the hardness adjuster 363 and the tightening locker 353 is described in detail. For the same structure of the two, a brief introduction is given.

As shown in FIG. 14, the hardness adjuster 363 includes a box body 52, which is similar to the box body 42 of the tightening lock 353, and is also in the shape of a cylinder with one end open, and a spine is formed on the inner periphery of the edge of the opening. Teeth 523, and include a hollow main shaft 522 in the center of the bottom surface. There are two openings (one shown in the figure) 521 at the bottom of the circumferential wall of the box body 522, and the adjustment wire 362 enters the box body 52 from the two openings 521 and is wound on the bobbin 54.

The difference from the tightening lock 353 shown in FIG. 11 is that the main shaft 522 is not provided with a winding spring in the box 52, but a tension spring 53 is provided. The tension spring 53 is, for example, a spring The open circle formed by the steel wire is formed with

wire loops

531 and 532 at two opposite ends of the opening, and a circle 533 is formed in the middle part. The circle 533 in the middle part is used to increase the elasticity of the tension spring 53. The two wire ends of the adjustment wire (not shown in FIG. 14) respectively enter from the two openings 521 and pass through the

wire loops

531 and 532, and are wound on the spool 54 so that the spool 54 is in the first direction (or wound When rotating in the direction), tighten the adjustment wire 362 from both ends at the same time. While the spool 54 is winding the adjustment wire 362, the two

wire loops

531 and 532 are pulled in a direction approaching each other, whereby the tension spring 53 imparts tension to the adjustment wire 362.

The spool 54, the gear cover 55, the locking member 56, the locking nut 57, and the knob 58 have the same structure as the corresponding structure in the tightening and locking device 353, so they will not be described again.

When it is necessary to further tighten the adjustment wire 362 and thereby increase the hardness of the outer shoe 3, turn the knob 58 in the first direction (winding direction), the knob 58 drives the gear cover 55, and the gear cover 55 drives the spool 54 to rotate, thereby tightening调线362。 Regulation line 362. Since the pawl 552 of the tooth cover 55 is engaged with the ratchet tooth 523 of the box body 52, the tooth cover 55 is prevented from reversing, and thus the spool 54 is prevented from rotating in the direction of releasing the adjustment wire 362.

When the adjustment wire 362 needs to be loosened, the knob 58 is rotated in the opposite direction, and the knob 58 initially rotates in the slit 551, so that the shift fork of the knob 58 stretches the locking member 56 and the opened locking member 56 is no longer affected. The shoulder of the lock nut 57 is constrained, so that the knob 58 and the tooth cover 55 can be pulled outward along the main shaft 552, so that the teeth of the tooth cover 58 are disengaged from the groove 541 of the spool 54 so that the spool 54 can rotate freely At this time, the tension spring 53 relaxes the tension in the adjustment wire 362 under the action of its own elastic restoring force.

5. Outer boot sole 31

The outer boot 3 is mainly used as a transition piece between the inner boot, the snowboard and the holder, which can improve the control hardness of the snowboard, and does not affect walking on the snow after being separated. Therefore, the sole 31 of the outer boot 3 is provided There are a number of patterns, bumps and pits in order to improve the occasional adhesion of the outer shoe 3 and to quickly discharge the snow that may be brought in by the inner shoe.

As shown in FIG. 15, the sole 31 is provided with bumps 311 at the inner and outer edges of the forefoot and the back of the foot, and two rows of bumps 311 are also provided at the centerline of the sole 31. A dimple 312 is included between the edge bump and the bump at the center line.

At the toe and heel positions, a continuously closed raised rib 313 is provided, and the raised rib 313 encloses a recessed space 314.

In addition, the position of the upper of the outer boot close to the sole includes a plurality of spaced openings (not marked). The openings may be located on the inner and outer sides of the outer boot to discharge snow that may be carried in by the inner boot.

By setting bumps and ribs, the outer boots can better grasp the surface of the snow, and by setting pits and recessed spaces, it can provide space for accommodating snow and prevent snow from accumulating between the sole and the ground. So as to avoid the decrease of the adhesion of the sole.
