Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ski boot, and more particularly to a ski boot having a mechanism for adjusting forward lean strength.

[0002]

[Prior art]

 Ski shoes in recent years are composed of an outer shell molded from a rigid plastic material such as polyurethane, and inner boots mounted inside the outer shell to hold the foot without gaps. In addition, in order to comfortably hold the foot 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 get a sense of unity between the foot and ski boots.

By the way, conventionally, a ski shoe of this type is provided with a slit on the back side of a shell body constituting an outer shell for the purpose of improving the foot putting property or the adhesion of the ankle. However, if a slit is provided on the back side of the shell body in this way, the forward leaning strength is weakened, and it is not possible to obtain sufficient strength to maintain the forward leaning attitude when making a turn by skiing. It was pointed out that was not stable.

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. 8 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 main body 7 and the trunk portion 9 forming 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 addition, 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. At that time, it was pointed out that this was a hindrance, it was difficult to cover, and it looked bad.

In addition, since the forward lean strength adjusting mechanism 3 projects to the outside in this way, it is damaged by an edge or the like during ski operation and adjustment becomes impossible. For example, when a 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 such circumstances, and prevents the forward leaning strength adjusting mechanism from protruding from the outer periphery of the ski boot to prevent damage to the forward leaning strength adjusting mechanism due to edges or the like. An object of the present invention is to provide a ski boot equipped with a forward lean strength adjusting mechanism capable of ensuring sufficient forward lean strength.

[0009]

[Means for Solving the Problems] In order to achieve such an object, a device according to claim 1 comprises a shell main body and a body portion tiltably attached to both side portions of the shell main body through connecting portions. In a ski boot equipped with a tightening device on the front portion of the outer shell, an upper connecting portion that connects the shell body and the trunk portion is separately provided above the connecting portion, and the upper connecting portion is attached to the outer shell. It is characterized in that it can be displaced vertically.

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. It is provided on the lower rear side of the outer shell, and an upper connecting portion is provided above the connecting portion. The invention according to claim 3 is the ski boot according to claim 1 or 2, wherein the upper connecting portion is a plurality of engaging holes provided in the shell body in the vertical direction of the outer shell. It is characterized in that it is composed of a plurality of engaging holes provided on the body side corresponding to these engaging holes and an engaging member engaging these.

[0011]

[Action]

 According to the ski shoe of the first aspect, by displacing the upper coupling portion to the lower side of the outer shell, the forward lean strength is reduced. That is, in the ski shoe according to the present invention, the connecting portion serves as the fulcrum and the upper connecting portion serves as the point of action. However, if the distance between both connecting portions is short, the forward leaning strength is weak due to the leverage principle, and The forward tilting strength increases as the distance between the connecting portions increases.

Therefore, by displacing the upper coupling portion above the outer shell, the forward tilt strength is largely changed. 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. As compared to the conventional case, a longer distance is provided between the body tightening device and the lapping range, and as a result, the body is tightened more firmly.

Further, in the ski boot according to a third aspect, the forward leaning strength of the trunk is adjusted by changing the engagement position of the engagement hole between the shell body and the trunk in the vertical direction of the outer shell. Become.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a ski shoe according to claims 1 to 3, wherein 27 is a ski shoe, and the ski shoe 27 is a hard and tough polyurethane similar to a conventional ski shoe. The outer shell 29 is made of the plastic material and the inner boot 31 mounted in the outer shell 29.

The outer shell 29 is mainly composed of a shell main body 33 that covers a lower part from 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 forward and backward through the connecting portion 39 in accordance with the forward leaning posture of the skier.

On the other hand, the shell main body 33 includes a shell bottom portion 41 having a split overlapping portion which 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. And a shin pad 43 arranged on the front surface of the portion 35. The above-mentioned shin pad 43 is a ladle-shaped tongue whose tip side is formed wide along the tip shape of the shell bottom 41, and is made of the same material as the shell bottom 41 and in a shape substantially matching the front surface thereof. And is attached to the toe side of the shell bottom 41 and the lower part of the upper region with screws 45. 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 configuration, the ski shoe 27 according to the present embodiment has the upper connecting portion 55 that connects the shell body 33 and the body portion 35 above the connecting portion 39 as shown in FIG. The outer shell 29 is characterized in that it is separately provided on the rear side of both sides.

As shown in FIG. 3, the upper connecting portion 55 is provided with two circular engaging holes extending rearward from both side portions of the shell body 33 and provided rearward of both side portions of the shell body 33. 57, 59, two circular engagement holes 61, 63 provided in the body portion 35 corresponding thereto, and an engagement member 65 for engaging them as shown in FIG. The engaging holes 57 and 59 and the engaging holes 61 and 63 are provided in the vertical direction of the outer shell 29, respectively.

The engagement member 65 is attached to the inside of the shell bottom portion 41, and an engagement plate 69 provided with a cylindrical nut portion 67 that can be fitted into the engagement holes 57 and 59 is provided. The head 71a of the screw 71 has a larger diameter than the engaging holes 61 and 63. The screw 71 is inserted into the fitting holes 61 and 63 and can be screwed into the nut portion 67. Then, as shown in FIG. 4, the mounting position of the engaging plate 69 in the engaging holes 57 and 59 is changed to change the screwing position of the screw 71 so that the forward lean strength of the body portion 35 can be adjusted. Has become.

In addition, in FIG. 1, reference numeral 73 denotes a slit formed on the back side of the shell body 33. As shown in FIG. 2, in the ski shoe 27 according to the present embodiment, a substantially U-shape is formed on the back side of the shell body 33. One slit 73 is formed. Further, in FIG. 4, reference numeral 75 denotes a blind cover, for example, as shown in FIG. 4, when an engaging plate 69 is attached to one engaging hole 59 and the engaging hole 63 is connected with a screw 71, the other engaging member is engaged. The joint holes 57 and 61 communicate with each other and open.

Therefore, the engaging holes 61, 63 on the body portion 35 side are provided with engaging portions 61a, 63a capable of engaging with the engaging piece 75a provided at the insertion side end of the blind cover 75. In FIG. 4, the locking piece 75 of the blind cover 75 is locked to the locking portion 61a of the engaging hole 61 so that the engaging hole 61 is closed by the blind cover 75. . Since the ski shoe 27 according to the present embodiment has such a structure, in order to ski, the foot may be inserted into the inner boot 31 and the tightening devices 47 and 53 may be tightened as in the conventional case.

Generally, an advanced person wants a ski shoe having a large forward leaning strength, and a soft ski boot having a small forward leaning strength is desired as a beginner, but the forward leaning strength of the ski shoe 27 is set to be small. As shown in FIG. 4, the engaging plate 69 is attached to the engaging hole 59 below the shell main body 33, and the engaging plate 63 is connected to the engaging hole 63 on the body portion 35 side with a screw 71. May be attached to the engagement hole 61.

When the lower engaging holes 59 and 63 are thus connected by the screw 71, the connecting portion 39 serves as a fulcrum and the upper connecting portion 55 serves as an operating point. When the distance is short, the forward tilt strength is weak due to the leverage principle, and when the distance between the connecting portions 39, 55 is long, the forward tilt strength is strong. Therefore, when the upper engaging holes 57, 61 are connected by the screw 71. In comparison, the ski shoe 27 has a weaker forward lean strength.

Therefore, the shell main body 33 and the body portion 35 are further integrated by connecting the upper engaging holes 57 and 61 with screws 71 instead of connecting the engaging holes 59 and 63. The ski shoes 27 having a high inclination strength can be obtained. Furthermore, in the conventional example shown in FIG. 8, it is necessary to secure a certain distance between the forward lean strength adjusting mechanism 3 and the connecting portion 23 in order to effectively function the forward lean strength adjusting mechanism 3. is there. 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 the present 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 outer shell 29 and the tightening device 53, and the lapping range is widened, and as a result, the body portion 35 is firmly tightened.
