Description

Snowboard boots and snow boots

technical field

The present disclosure relates to a snowboard boot, and more particularly to a snowboard boot comprising an outer boot and an inner boot, wherein the inner boot can be adapted to everyday life like a normal boot for walking, driving, etc., and is easily integrated with the outer boot. Boot fit, thus suitable for snowboarding needs. If it is matched with special thermal insulation outer boots with enhanced thermal insulation, it is more suitable for long-distance walking in a low-temperature environment and the needs of long-term outdoor activities.

Background technique

Snowboarding, also known as skateboarding, originated in the United States in the mid-1960s, and its production is related to surfing. Sherman Poppin tied two skis together in 1965, and accidentally created a new "snowboard" with two feet stepping on a whole board. Snowboarding is also known as winter surfing. Instead of a pair of skis, one ski uses the body and feet for steering.

As shown in Figure 1, there are two anchors fixed at intervals on the snowboard. The skier stands sideways on the snowboard and buckles the ski boots on the anchors, and controls the movement of the snowboard by leaning back and forth. As shown in Figures 1 and 2, two bindings are installed on the snowboard 10 and include a strap 15 and a high back 16, the strap 15 can be tightened on the vamp of the snowboard boot 12, and the high back 16 The back of the snowboard boot 12 is supported, thereby fixing the snowboard boot to the snowboard.

Existing snowboards mostly adopt soft boots, although this soft boots are relatively light and soft compared with ski boots. But for the needs of controlling the snowboard, it is still relatively hard and bulky, only specially suitable for snowboard ski boots, therefore, it is not convenient to use in daily life. In addition, if the hardness between the boot shaft and the vamp of such soft boots is low, it is not conducive to controlling the snowboard when skiing. In addition, there is also a snowboard boot that includes an inner boot and an outer boot, but the inner boot is difficult to pull out and put in from the outer boot, resulting in inconvenience in the use of this snowboard boot. In addition, this includes an inner boot. Ski boots with outer boots also have the problem of low stiffness, which is not conducive to ski control.

In addition, snowboarding is different from double-boarding. Snowboarding requires the skier to use the body to control the skiing action, forward direction, speed, etc. Therefore, the requirements for the hardness of ski boots are higher than those of double-board skiing. , In addition, different skiers may need different hardness due to skills and other reasons, but the current ski boots cannot adjust the hardness of ski boots. Another problem with traditional ski boots is that the hardness of the ski boots gradually decreases with the prolongation of use time, thus failing to meet the hardness requirements.

Accordingly, a need exists for improved snowboard boots.

In the back part, small locking buckles 107 and large locking buckles 108 are fixed, wherein the corresponding small locking buckles 107 are staggered from each other, and at the position of the upper near the shoe opening, large locks are respectively fixed on the inner side and the outer side. Buckle up 108.

As shown in Figure 5, the shoelace buckle 106 is similar to a flat saddle shape, including a notch 1063, so that it can be fixed on the upper of the shoe through the loop 1062, and on the outer surface of the shoelace buckle 106, a plurality of protrusions 1064 are arranged. Protrusion 1064 is formed with a tip, for example, to increase attachment to loop 1062 . A winding channel 1061 is formed on the inner side of the buckle 106, and the winding channel 1061 is, for example, arc-shaped, thereby reducing the resistance when the shoelace is pulled.

As shown in Fig. 3, on the inner and outer back part 1032, a plurality of small locking buckles 107 are arranged, and as shown in Fig. 6A and 6B, the small locking buckles 107 include a base plate part with a larger diameter and a roughly circular shape. 1071. The main body part 1072 extending upward from the bottom plate part 1071 forms a wire slot 1073 at the approximate center of the thickness direction of the main body part 1072. The cross section of the wire slot 1073 is generally arc-shaped and shrinks inward, that is, Roughly wedge-shaped, thereby reducing the friction of the shoelace and preventing the shoelace from backing out and loosening as the shoelace snaps in. In addition, the wire groove 1073 does not have to be arranged around the entire circumference of the main body portion of the small locking buckle, but can be arranged on about three quarters of the circumference. The small locking buckle 107 is fixed on the shoe upper by various suitable methods such as riveting and bonding, and the present disclosure is not limited to any specific form.

As shown in Figure 3 and Figures 7A to 7D, a large locking buckle 108 is fixed symmetrically on the upper part of the shoe near the shoe opening, and the large locking buckle 108 is arranged to allow the shoelace to be locked in the tensioning direction. and prevent the laces from unraveling. 7A to 7D show various views of the large locking buckle 108, wherein, FIG. 7A shows a perspective view of the large locking buckle 108, and FIG. 7B shows a cross-sectional view taken along line B-B in FIG. 7D , 7C shows a cross-sectional view taken along line C-C in FIG. 7D, while FIG. 7D is a top view of locking buckle 108 with a portion removed along line D-D in FIG. 7B to show the lace in/out channel.

As shown in Figures 7A to 7D, the large locking buckle 108 includes a larger diameter base portion 1081, a body portion extending from the base portion 1081, the body portion includes a bottom portion 1082 and a cover portion 1083, between the base portion 1082 and the cover A wire winding groove 1084 is formed between the upper parts 1083, as shown in Figure 7B and 7C, the cross section of the wire winding groove 1084 is wedge-shaped, and the opening size becomes smaller toward the center of the large locking buckle 108, thus, in When the shoelace is wound on the locking buckle 108, as the shoelace is tightened, the shoelace will be wedged into the depth of the wedge-shaped winding groove 1084, thereby preventing the shoelace from loosening.

As shown in Figure 7D, there are also shoelace in/out passages 1085, preferably two, which are symmetrically arranged on both sides of the locking buckle 108, thereby allowing the shoelace to pass from any One direction protrudes into the winding groove 1084 and winds in any direction. Lace entry/exit channel 1085 preferably includes tapered openings at both ends to allow for easy threading of shoelaces.

Below with reference to Fig. 3 briefly describe the winding method of shoelace:

The starting end of the shoelace 105 is knotted, so that the length of the shoelace can be adjusted by adjusting the position of the knot. After knotting, the starting part of the shoelace starts to wrap around the first pair of shoelace buckles 106 from the toe, and after extending through the shoelace buckles 106, the shoelaces 105 alternately wrap around the small locking buckles 107, due to the small locking The buckle 107 is formed with a groove with a circular arc cross section, which is beneficial to the smooth sliding of the shoelace 105 . After extending over the small locking buckle 107, the shoelace 105 is wrapped around the large locking buckle 108. According to the user's preference, the shoelace 105 can be wound around the large locking buckle 108 from any direction, and the remaining length of the shoelace 105 Wind the large locking buckle 108 for one or more turns, and then fix the tail end of the shoelace 105 on the upper of the shoe. In order to fix the tail end of the shoelace 105, for example, an engaging device such as a Velcro strap 109 (Velcro) is provided on the tail end of the shoelace, and a matching buckle strap ( engaging elements, not shown), the buckle strip 109 at the tail end of the shoelace can be glued to a mating buckle strip, thereby securing the end end of the shoelace. However, other forms of Velcro or hooks can also be used, and the present invention is not limited to Velcro.

As shown in Figures 3 and 4, in the state shown in Figure 4, the skier can easily insert his foot into the boot 1, the shoelace will not come off from the shoelace buckle 106 but will remain on the shoelace On the belt buckle 106, like this, the skier can grasp it with one hand, because the small locking buckle 107 and the large locking buckle 108 have a wedge-shaped cross section, play a role in preventing the shoelace from retreating and loosening, and preventing it from being pulled tightly If the shoelace 105 is loosened, the shoelace 105 can be easily tightened to a predetermined degree even with one hand even if the shoelace is loosened temporarily.

Although a specific embodiment of the inner boot according to the present disclosure has been described in detail above, it should be pointed out that the present disclosure is not limited thereto, and the outer boot of the present disclosure can be combined with any other form of inner boot, for example, an ordinary daily Inner boots for daily life, used together. Additionally, although the inner boot is described herein with reference to a snowboard boot, it should be understood that the inner boot can also be mated with the outer boot of a ski boot to form a snowboard boot.

Two, outer boots 3

The outer boot 3 according to the present disclosure will be described below with reference to FIGS. 8 to 13B . The outer boot 3 is made of harder material to meet the needs of controlling the snowboard in skiing. The material is for example: TPU (thermoplastic polyurethane elastomer rubber), PVC, PE, PP, etc., wherein TPU is the preferred material due to its excellent low temperature performance.

As shown in FIGS. 8 and 9 , the outer boot 3 includes a sole 31 , an upper 32 , a tongue 33 , and a boot 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 also includes a lateral side toe portion 321 and a medial side toe portion 321, the middle portion 322 includes a lateral middle portion 322 and a medial middle portion 322, and a heel portion 323 A lateral heel portion 323 and a medial heel portion 323 are included. The boot shaft 34 is a one-piece shaft closed at the rear side, which is only open at the front side to receive the tongue 33 .

The tongue 33 is hinged to the rear end of the toe portion 321 , whereby the tongue 33 can pivot forward so that the outer boot 3 is in an open configuration (as shown in FIG. 11 ). In this configuration, the inner boot 1 can be easily inserted into the outer boot 3 or taken out of the outer boot 3 . After the inner boot 1 is inserted into the outer boot 3 or after the inner boot 1 is taken out of the outer boot 3, the tongue 33 can be pivoted back to the closed position (as shown in FIGS. in the front opening of the boot, thereby placing the outer boot 3 in the closed configuration. In order to maintain the closed configuration of the outer boot 3, a closed tightening locking assembly 35 is provided on the upper part of the outer boot tube portion 34, and the closing tightening locking assembly 35 includes a locking wire 351 and a tightening locker 352, This locks the tongue 33 in the closed position (as shown in FIGS. 8 and 9 ).

Thus, when the tongue 33 needs to be opened to place the outer boot 3 in the open configuration, the tightening lock 352 can be released, so that the tongue 33 can stretch out from the front opening of the boot tube 34 and In an open configuration (see FIG. 11 ), in one embodiment, a biasing device (not shown), such as a torsion spring, may be provided at the junction of the tongue 33 and the toe portion 321 to push the tongue 33 biased to the open position. After the inner boot 1 is inserted, tighten the locking device 352 to tighten the locking wire 351 again, so that the outer boot 3 is in a closed configuration (as shown in FIGS. 8 and 9 ).

The tightening locker 352 can be, for example, a locker as disclosed in the applicant's previous Chinese application No. 201920465886.5 or any locker as disclosed in the applicant's previous PCT application PCT/CN2018/102522, these The application is hereby incorporated by reference in its entirety and will not be described in detail.

In order to lock the outer boots, a plurality of wire grooves 353 are arranged on the upper, so that the locking wire 351 passes through multiple positions along the wire grooves 353 from the boot surface and the upper surface, and in particular, the locking wires 351 passes through a plurality of locations on the tongue 33, for example three locations including a first location at approximately the top of the tongue, a second location near the tongue's kink point, and at The third position near the hinged position of the tongue and the toe, by passing through the locking wire 351 at the above three positions, when the locking wire 351 is tightened by the locking device 352, the tongue 33 can be firmly tied to the On the boot tube 34.

On one side of the surface of the tongue 33, a guard plate 36 is also provided. The guard plate 36 is formed by a material with a hardness higher than that of the tongue. It is fixed to the tongue by fasteners such as rivets and screws. As an example, as shown in Figure 7, a plurality of bosses 361 are formed on the side of the guard plate 36 facing the tongue 33, and threaded holes (not shown) are formed in the bosses 361, and screws (not shown) are used to The shield 36 is secured to the tongue 33 through the tongue 33 . At the same time, the boss 361 forms a gap between the tongue and the guard plate, through which the above-mentioned locking wire 351 passing through the first position and the second position can extend, thereby, when the tongue 33 is pivoted forward to When the outer boot is placed in the open configuration, the locking line 351 can freely move up and down in the gap, thereby preventing the locking line 351 from hindering the tongue 33 from opening.

Since the guard plate 36 is formed of a harder material than the tongue 33, the guard plate 36 increases the stiffness of the entire outer boot 3, thereby allowing the skier to better manipulate the outer boot to control the snowboard. In addition, the existence of the guard plate 36 can also play a protective role, preventing snow from entering the outer boots during skiing, and also plays the role of keeping out wind and keeping warm.

The outer boot 3 is also provided with a hardness adjustment assembly, 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 skis. The hardness adjustment assembly 40 will be described in detail below with reference to FIGS. 12A to 13B .

As shown in FIGS. 8 to 11, the outer boot 3 includes a boot shaft 34 and a vamp 32. The boot shaft 34 is connected to the vamp 32 at a pivot point 341 by rivets or other fasteners, so that the skier can When the ski boot is tilted, the boot shaft 34 can pivot slightly around the pivot point 341 , as shown by the double arrow B in FIG. 13 .

As shown in Figures 12A and 12B, in order to clearly see the stiffness adjustment assembly 40 therein, a portion of the shoe structure is removed. On each side (inside and outside) of the outer boot, a channel 41 is formed at the rear end of the boot shaft 34, in which a spring 42 is accommodated, the lower end of which spring 42 is fixed to the lower end of channel 41 and the upper end of the spring is fixed to The hardness adjustment wire 43, for example, is by hardening the part in the spring of the adjustment wire 43 and welding the upper end of the adjustment wire 43 to the spring upper end, or the upper end of the adjustment wire 43 can be fixed with a block 48 whose diameter is larger than The inner diameter of the spring coils, thereby snapping onto the upper end of the spring, is not a limitation of this disclosure. And the other end of the hardness adjustment line 43 is fixed on the hardness adjustment mechanism in the heel (see FIGS. 12A and 12B ), so that when the skier leans forward, the boot shaft pivots slightly around the pivot point 341, thereby adjusting the hardness. The wire 43 pulls the spring 42, and the elastic force of the spring 42 provides the outer boot (or the ski boot including the inner boot) with stiffness or elastic force for leaning forward.

As shown in Figures 13A and 13B, in the rear end of the sole 31, an accommodation space is formed, and a hardness adjustment mechanism is accommodated in the accommodation space. The hardness adjustment mechanism includes an adjustment block 44, a threaded rod 45, and a guide rail 46. The adjustment block 44 can be Slide along the guide rail 46 , and the threaded rod 45 is threadedly connected with the adjustment block 44 , so that the adjustment block 44 can be driven to move back and forth along the guide rail 46 by turning the threaded rod 45 . The hardness adjustment wire 43 is fixed on the adjustment block 44, or the hardness adjustment wire 43 can bypass the adjustment block 44 and extend to the other side of the outer shoe to be connected to the upper end of the spring on the other side. An adjustment hole 47 is formed at the rear end of the sole, whereby an adjustment wrench (screwdriver or hex wrench) can be inserted into the adjustment hole 47 to drive the threaded rod 45 to rotate, thereby moving the position of the adjustment block 44 . The forward movement of the adjustment block 44 will pull the stiffness adjustment wire 43, thereby tensioning the spring 42, and the tensioned spring 42 will provide greater stiffness to the ski boot.
