Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ski shoe, and more particularly to a ski shoe having a simple structure and ensuring a sufficient forward leaning strength.

[0002]

[Prior art]

 Recent ski boots are composed of an outer shell formed of a rigid plastic material such as polyurethane, and an inner boot mounted in the outer shell to hold the foot without a gap. In addition, in order to hold the foot comfortably and improve the operability of the ski, in front entry type ski shoes, each part of the outer shell corresponding to the ankle and instep areas of the inner boots is tightened with tightening devices. It is tightened to create a sense of unity between the foot and ski boots.

By the way, conventionally, in this type of ski boot, a slit is provided in the rear portion of the shell body constituting the outer shell for the purpose of improving the foot insertion property or the adhesion of the ankle. However, if a slit is provided in the rear part of the shell body in this way, the slit part softly bends when leaning forward, and the ankle's adhesion is obtained, but on the other hand, the strength of leaning forward becomes weaker, and when making a turn by skiing, It was pointed out that the posture was not stable because sufficient strength to maintain the leaning posture was not obtained.

Therefore, recently, many ski shoes are equipped with a forward lean strength adjusting mechanism which also has a forward lean angle adjusting function as disclosed in Japanese Patent Laid-Open No. 142202/1982. FIG. 7 shows a ski boot provided with such a forward lean strength adjusting mechanism. The forward lean strength adjusting mechanism 3 of the ski shoe 1 is provided on the back side of the shell body 7 and the body portion 9 which form the outer shell 5, respectively. The projecting portions 11 and 13 are formed, and between the projecting portions 11 and 13, there are screw threads 15a and 15b extending in opposite directions, and an adjusting knob 17 fixed between the screw threads 15a and 15b. The adjusting spindle 15 is arranged, and a guide pin 21 that engages with the adjusting spindle 15 and holds a spring 19 is held by the protruding portion 11 and the protruding member 13 so as to be slidable in the longitudinal direction.

According to the forward tilt strength adjusting mechanism 3, the adjusting knob 17 is rotated to slide the inner pin 21 in the longitudinal direction, so that the shell body 7 and the body portion 9 are connected to each other. The forward tilt angle of the body 9 can be adjusted around the portion 23, and the compression distance of the spring 19 can be changed to adjust the forward tilt strength of the body 9. In the figure, 25 is a body tightening device.

[0006]

[Problems to be solved by the device]

 However, in the conventional ski shoe 1 as described above, since the forward lean strength adjusting mechanism 3 has a structure projecting to the back side of the ski shoe 1, the upper portion of the ski shoe 1 is covered by the hem of the ski wear. It was pointed out that it was an obstacle and it was difficult to cover and it looked bad.

Further, since the forward lean strength adjusting mechanism 3 protrudes to the outside in this way, it is damaged by an edge or the like during ski operation and adjustment becomes impossible, and, for example, when the skier collides with another skier during skiing. However, there is a risk that the skier may be injured by the adjusting mechanism 3, and there is a problem in terms of safety. Furthermore, in the forward lean strength adjusting mechanism 3, since the compression distance of the spring 19 with respect to the forward lean motion is short, the effect of the spring force cannot be sufficiently exerted, and a sufficient forward lean strength cannot be secured. Was pointed out.

The present invention has been devised in view of the above circumstances, and provides a ski shoe that has a simple structure and ensures sufficient forward lean strength while taking advantage of the slit provided in the rear portion of the shell body. The purpose is to do.

[0009]

[Means for Solving the Problems] In order to achieve such an object, a device according to a first aspect of the present invention provides a shell main body having a slit formed in a rear portion, and tilting via a connecting portion on both sides of the shell main body. In a ski boot in which a tightening device is attached to a front portion of an outer shell that includes a torso that can be attached, a reinforcing member is erected on the shell main body while sandwiching the slit.

According to a second aspect of the present invention, in the ski boot according to the first aspect, the lower end portions on both sides of the trunk portion are extended in the heel direction of the shell body to form a connecting portion with the shell body. The ski boot according to claim 3 is provided on the lower rear side of the outer shell, and in the ski boot according to claim 1 or 2, the reinforcing member can be displaced in the vertical direction of the shell body. It is characterized by

[0011]

[Action]

 According to the ski boots according to each claim, when the front leans, the reinforcing member increases the front lean strength for preventing the slit portion from bending more than necessary and maintains the forward lean posture, and when the back leans, the reinforcing member is used. This prevents the slits from expanding and improves the holding power of the ski boot.

In the ski boot according to claim 2, the lower end portions on both sides of the trunk portion are extended in the heel direction of the outer shell, and the connecting portion with the shell body is provided on the lower rear side of the outer shell. Since it is installed, a long distance is provided between the body tightening device and the body tightening device, and the lapping range is widened. As a result, the body is tightly tightened. Further, in the ski boot according to the third aspect, the forward leaning strength of the trunk is adjusted by changing the mounting position of the reinforcing member in the vertical direction of the outer shell.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a first embodiment of a ski shoe according to claims 1 and 2, wherein 27 is a ski shoe, and the ski shoe 27 is a hard and tough polyurethane similar to conventional ski shoes. The outer shell 29 is made of a plastic material such as the above, and the inner boot 31 is mounted inside the outer shell 29.

The outer shell 29 is mainly composed of a shell main body 33 that covers the lower part of the ankle and a body part 35 that integrally covers the lower part of the ankle and the lower part of the calf, and the body part 35 is As shown in FIGS. 1 and 2, the lower end portions on both sides thereof extend in the heel direction of the shell body 33 and are connected to the lower rear side of the shell body 33 via a pin 37. Further, the trunk portion 35 can be tilted in the front-rear direction according to the forward leaning posture of the skier via the connecting portion 39.

On the other hand, the shell body 33 includes a shell bottom portion 41 having a split overlapping portion that is split left and right from the upper opening to the instep region, and a shell bottom portion 41 covering the split overlapping portion from the toe side of the shell bottom portion 41 to the body. It is composed of a shin pad 43 arranged on the front surface of the portion 35, and one slit 45 is formed in a substantially U shape at the rear portion of the shell bottom portion 41 as shown in FIG.

The shin pad 43 is a ladle-shaped tongue piece whose tip side is formed wide along the tip shape of the shell bottom portion 41, and is made substantially the same as the front surface portion by the same material as the shell bottom portion 41. It is formed into a shape, and is attached to the toe side of the shell bottom 41 and the lower part of the upper region with screws 46. Then, a through hole 49 through which the tightening cable 47a of the tightening device 47 that tightens the instep region of the shell body 33 penetrates, and a locking member 47b of the tightening device 47 is arranged on the shin contact member 43 in the shin contact member 43. A recess 51 is formed so that the upper region of the shell body 33 is tightened by the tightening operation of each tightening device 47.

Similarly, the front portion of the body portion 35 is also divided into left and right to form a divided overlapping portion, which is overlapped with each other, and the upper and lower two tightening devices 53 attached to the divided overlapping portion can be operated. Then, the body portion 35 is tightened together with the shin pad 43. Thus, in addition to the above-described structure, the ski shoe 27 according to the present embodiment has a reinforcing plate (reinforcing member) 55 at the rear portion of the shell bottom portion 41 with the slit 45 interposed therebetween as shown in FIGS. 2 and 3. It is characterized by being installed.

The reinforcing plate 55 is a band-shaped hard plate made of carbon fiber reinforced resin, and is formed into a curved shape along the ankle shape of the skier. As shown in FIG. 2, the reinforcing plate 55 is located slightly below the upper opening 45a of the slit 45 and is fixed to the shell bottom 41 with a fixing pin 57. The slit 45 is prevented from flexing more than necessary (tightening to the ankle) at the time, and the reinforcing plate 55 prevents the slit 45 from expanding when tilting backward.

Since the ski shoe 27 according to the present embodiment is configured in this way, in order to ski, the foot is inserted into the inner boot 31 and the tightening devices 47 and 53 are tightened as in the conventional case. Good. At this time, since the slit 45 is provided in the rear portion of the shell body 33, the foot insertion property is good as in the conventional case. Then, at the time of gliding, the trunk portion 35 tilts in the front-back direction via the connecting portion 39 in accordance with the movement of the skier, but as described above, at the time of forward leaning, the reinforcing plate 55 bends the slit 45 portion more than necessary. In addition, the reinforcing plate 55 prevents the slit 45 from expanding when tilting backward.

Furthermore, in the conventional example shown in FIG. 7, in order to make the forward lean strength adjusting mechanism 3 effectively function, a certain distance is secured between the forward lean strength adjusting mechanism 3 and the connecting portion 23. There is a need. Therefore, as shown in the figure, conventionally, the connecting portion 23 is arranged near the ankle of the outer shell 5. However, due to the structure in which the connecting portion 23 is arranged near the ankle, the connecting portion 23 and the body tightening device are arranged. It has been pointed out that the distance R ₁ with 25 cannot be secured, the lapping range is narrowed, and sufficient tightening force of the body 9 cannot be obtained.

However, in this embodiment, as shown in FIG. 1, the lower end portions on both sides of the body portion 35 are extended in the heel direction of the shell body 33 to form a connecting portion 39 with the shell body 33. Since it is provided on the lower rear side of the outer shell 29, a longer distance R ₂ is provided between the body portion 35 and the tightening device 53 of the body portion, and the lapping range is widened as a result, so that the body portion 35 is firmly tightened. It will be.

As described above, in the ski shoe 27 according to the present embodiment, the reinforcing plate 55 is installed on the rear portion of the shell bottom portion 41 with the slit 45 sandwiched therebetween, and the slit 45 portion is bent more than necessary when tilted forward. Since the slit 45 part is prevented from expanding when tilting backwards, a sufficient forward leaning strength to maintain a forward leaning posture can be obtained as compared with a conventional ski boot having a slit in the rear portion of the shell body. Further, even when the vehicle is tilted backward, the holding force of the ski shoe 27 is improved to facilitate holding of the body, and the structure is simple and lightweight. Of course, the provision of the slit 45 also provides good foot insertion.

Furthermore, in the ski shoe 27 according to the present embodiment, since there is no structure protruding from the outer periphery of the ski shoe 27 unlike the forward inclination strength adjusting mechanism 3 of the ski shoe 1 shown in FIG. It is easy to cover the upper part of the ski shoe 27 with the hem of the keywear, and the appearance of the ski shoe 27 is improved. In addition, the structure may be damaged due to an edge or the like during skiing, resulting in inoperability. Absent.

In addition, according to the present embodiment, the lower end portions on both sides of the body portion 35 are extended toward the heel of the shell body 33 to connect the shell body 33 to the shell body 33 corresponding to the conventional connecting portion 23. Since 39 is provided on the lower rear side of the outer shell 29, a longer distance R ₂ is provided between the tightening device 53 and the lapping range is widened as compared with the conventional one, and as a result, the tightening effect of the body portion 35 is dramatically increased. It will be improved.

Further, since it is possible to adjust the strength of the ski shoe 27 by changing the material of the reinforcing plate 55, if the reinforcing plate 55 has a replaceable mounting structure, the skier's skill level and slope conditions can be improved. Accordingly, it becomes possible to obtain the optimum forward tilting strength. FIG. 4 shows a second embodiment of the ski boot according to claims 1 and 2. In the first embodiment, a substantially U-shaped slit 45 is provided at the rear of the shell body 33 (shell bottom portion 41). The present invention is applied to one ski shoe 27 provided in this embodiment, but in the present embodiment, one vertical slit 63 is provided at the rear of both sides of the shell bottom 61 that constitutes the shell body 59 with the shin pad 43. In the ski shoe 65, a reinforcing plate 55 is installed behind the shell bottom 61 with both slits 63 sandwiched therebetween.

Since the other structures are the same as those of the first embodiment, the same components are designated by the same reference numerals and the description thereof will be omitted. Thus, according to this embodiment, the intended purpose can be achieved as in the case of the first embodiment. 5 and 6 show an embodiment of a ski shoe according to claims 1 and 3, and this embodiment will be described below with reference to the drawings. The same parts as those shown in FIG. No. and their explanations are omitted.

In the figure, like reference numeral 67, the ski shoe is composed of an outer shell 69 and an inner boot 31 like the ski shoe 27. The outer shell 69 includes a shell body 71 that covers a portion below the ankle and an ankle. The lower shell of the shin and the lower belly of the calf are integrally formed with a body portion 73, and the connecting portion 75 between the shell body 71 and the body portion 73 has an outer shell similar to that of the conventional ski shoe 1 shown in FIG. It is provided near the ankle of 69.

At the rear portion of the shell bottom portion 77 that constitutes the shell main body 71 together with the shin pad 43, one slit 79 is formed in a substantially U shape as in the embodiment shown in FIG. The reinforcing plate 55 is attached to the rear portion of the shell bottom portion 77 with the slit 79 interposed therebetween so as to be displaceable in the upward and downward directions. That is, as shown in FIG. 6, three mounting holes 81, 83, 85 are formed at equal intervals in the vertical direction at the rear of the shell bottom 77 with the slit 79 sandwiched between them. A reinforcing plate 55 is attached to the shell bottom portion 77 via a mounting pin 87 that can be attached to and detached from 85.

By attaching the reinforcing plate 55 to the attaching holes 81 and 83, the reinforcing plate 55 is attached to the upper part of the slit 79 as shown by the solid line in FIG. 6, and the reinforcing plate 55 is attached to the attaching holes 83 and 85. Then, the reinforcing plate 55 is attached to the lower part of the slit 79 as shown by the chain double-dashed line. The ski shoe 67 according to the present embodiment is configured in this way, and like the above-described embodiments, the reinforcing plate 55 prevents the slits 79 from flexing more than necessary when leaning forward, and strengthens when leaning backward. The plate 55 prevents the slit 79 from expanding. However, when the reinforcing plate 55 is attached to the mounting holes 81 and 83, the reinforcing plate 55 has a slit when compared to when the reinforcing plate 55 is attached to the mounting holes 83 and 85. Forty-five parts of the ski boot 67 are prevented from being bent more than necessary, and the reinforcing plate 55 further prevents the slits 45 parts from expanding when tilting backward, so that the ski boot 67 has a greater forward tilting strength.

Therefore, generally, an advanced person wants a ski shoe having a large forward leaning strength, and a beginner wants a soft ski shoe having a small forward leaning strength. However, in order to increase the forward leaning strength of the ski shoe 67, As described above, the reinforcement plate 55 may be attached to the attachment holes 81 and 83, and the reinforcement plate 55 may be attached to the attachment holes 83 and 85 to reduce the forward tilting strength.

As described above, according to this embodiment, it is possible to obtain the optimum forward lean strength according to the skier's technical level and the slope condition by changing the mounting position of the reinforcing plate 55. Even when leaning backward, the holding force of the ski shoe 67 is improved to make it easier to hold the body, and the structure is simple and lightweight. Further, since the slit 75 is provided, the foot can be easily inserted as in the conventional case.

Furthermore, even in the ski shoe 67 according to the present embodiment, there is no structure protruding from the outer periphery of the ski shoe 67 as compared with the ski shoe 1 shown in FIG. This makes it easier to cover the upper portion of the shoe 67, improves the appearance of the ski shoe 67, and prevents such a structure from being damaged by edges or the like during skiing and making it inoperable.

Although not shown, the reinforcing plate 55 in the embodiment of FIG. 1 can be displaced in the vertical direction as in the embodiment of FIG. 6 like the ski boots of claims 1 to 3. According to such a ski shoe, compared to the conventional case, a longer distance is provided between the tightening device and the lapping range, and as a result, the torso is firmly tightened and the reinforcing plate By changing the mounting position, it is possible to obtain the optimum forward lean strength according to the skier's skill level and the slope conditions.

Further, the material of the reinforcing plate 55 is not limited to the above-mentioned carbon fiber reinforced resin, but it is also possible to use a hard material such as FRP, hard urethane, hard rubber or the like.
