DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings by taking a so-called rear entry type ski boot as an example. FIG. 1 is a side view of a rear entry type ski shoe according to an embodiment of the present invention. In this ski shoe, the shell forming the outer shape includes a front shell 1, a rear shell 2, an instep shell 3, and a toe shell 4. Further, the shoe sole is connected to the instep shell 3, and the main sole 5 forming the bottom of the instep shell 3
And a toe sole 6 connected to the toe shell 4 and forming the bottom of the toe shell 4. The toe shell 4 and the toe sole 6 are flexibly connected to the instep shell 3 and the main sole 5. This is the greatest feature of this embodiment.

That is, in the conventional rear entry type ski boot, the upper shell 3 and the toe shell 4 are generally formed integrally. Further, the shoe sole was a flat plate-like sole formed integrally. On the other hand, in this embodiment, the toe shell 4 and the instep shell 3 are connected by the hinge pins 7 on the left and right side surfaces of each, and the toe portion is bendable.

A slide sole 10 is connected to the rear portion of the toe sole 6 via a link mechanism 9. Guide grooves (slide guides) 11 for guiding the slide sole 10 are formed on both left and right sides of the main sole 5. These link mechanism 9 and slide sole 10
The guide groove 11 will be described later in detail. Further, a cover bellows 12 is attached to a connecting portion between the instep shell 3 and the toe shell 4, and is closed so that water or the like does not enter the inside of the shoe through the connecting portion between the instep shell 3 and the toe shell 4.

A tightening lever 13 is attached to the rear shell 2. The tightening lever 13 is attached by a support pin 14 so as to be rotatable around its upper end, and the ski boot can be tightened in a hold state by tilting the lever 13 to the illustrated state. Further, the hold state can be released by lifting the tightening lever 13 in the direction of the arrow 1A.

Inner boots 15 are housed in these shells, as in conventional ski boots. Although not shown, a tightening wire is connected to the tightening lever 13, and the wire is pulled by the operation of the lever 13 to surely hold the foot put in the shoe.

Further, in this embodiment, the fixing wire 17 is connected to the tightening lever 13, and when the tightening lever 13 is tightened, the fixing wire 17 is pulled and slides as described later. The sole 10 is adapted to be pulled rearward.
FIG. 2 is a side view of the ski boot in which the toe shell 4 is bent upward by a predetermined angle with respect to the instep shell 3.

As shown in FIG. 2, the toe sole 6 and the toe shell 4 can be bent with respect to the main sole 5 and the instep shell 2. At the maximum bending, the toe sole 6 is bent at an angle θ with respect to the main sole 5. To do. Since the cover bellows 12 closes the space between the upper shell 3 and the toe shell 4, water or the like does not enter the shoe from the connecting portion between the upper shell 3 and the toe shell 4. Further, since the cover bellows 12 is a bellows as its name suggests and is expandable and contractible, it does not hinder the bending of the tow shell 4.

Next, the bendable mechanism in this embodiment will be described with reference to FIGS. 3 and 4.
FIG. 3 is a perspective view of a main part of a connecting mechanism between the main sole 5 and the toe sole 6, and FIG. 4 is a side view of the connecting mechanism. With reference to FIGS. 3 and 4, a link mechanism 9 is connected to the rear portion of the toe sole 6, and a slide sole 10 is connected to the rear portion of the link mechanism 9.

More specifically, connecting protrusions 18 projecting rearward are formed on the left and right sides of the rear portion of the toe sole 6, respectively. The link mechanism 9 includes a first roller 19 and a second roller
It has a roller 20 and a pair of links 21 connecting the first roller 19 and the second roller 20.
Roller 19, second roller 20 and pair of links 21
Are connected by connecting pins 22, respectively.
The first roller 19 is connected to the connecting protrusion 18 of the toe sole 6 by a connecting pin 22. Further, the slide sole 10 is formed with connection protrusions 24 on both left and right ends of the tip, and the connection protrusions 24 are connected to the second roller 20 by connection pins 22. Therefore tosole 6
The slide sole 10 and the slide sole 10 are bendable via the link mechanism 9.

Sliders 27 are provided on both left and right side portions 26 of the slide sole 10. On the other hand, guide grooves 11 are formed on the left and right side surfaces of the main sole 5, and the slider 27 is engaged with the guide grooves 11.
The slider 27 is guided by the guide groove 11 and is held so as to be slidable back and forth. Further, a pair of toe arms 28 extend upward and rearward from the left and right sides of the upper surface of the toe sole 6. Further, a pair of main arms 29 extends upward and forward on both left and right sides of the top surface of the main sole 5. The tip of the toe arm 28 and the tip of the main arm 29 are rotatably connected by a hinge pin 7.

Due to the above-described connection relationship, as shown in FIG. 3, when the tip of the toe sole 6 is bent so as to be lifted upward, the toe sole 6 rotates about the hinge pin 7, and the slide sole accordingly. 10 slides forward. Then, when the slider 27 moves forward along the guide groove 11 and reaches a predetermined position, the slide sole 10 cannot move forward any further, and as shown in FIG. 5 is the maximum bending state.

On the contrary, when the toe sole 6 is returned to the horizontal state,
The slide sole 10 moves rearward, the slider 27 moves rearward by being guided by the guide groove 11, and when the toe sole 6 becomes horizontal, the slider 27 cannot move further rearward, as shown in FIG. The toe sole 6 and the main sole 5 are in a straight horizontal state. And when trying to bend the toe sole 6 downward from the horizontal state,
The toe arm 6 and the slide sole 18 do not allow the toe sole 6 to bend further downward, and the toe sole 6 does not bend further than the horizontal state.

In the above description, the toe sole 6 has a pair of toe arms 28 extending from the left and right sides toward the upper rear.
Although the main sole 5 is provided with a pair of main arms 29 extending upward and forward from the left and right sides, the toe arm 28 may be integrally formed with the toe shell 4. .. Also, the main arm 2
9 may be integrated with the instep shell 3. Alternatively, as shown in FIGS. 3 and 4, the toe arm 28 and the main arm 29 are formed, and the toe shell 4 is formed from above.
Alternatively, the upper shell 3 may be covered.

FIG. 5 is a view for explaining the structure and operation of the slide sole 10. As shown in FIG. 5, the rear end portion of the slide sole 10 is a scraper 30 that is sharply sharpened. When the rear end of the slide sole 10 is the scraper 30 as described above, there is an advantage that the scraper 30 scrapes off snow, mud and the like adhering to the bottom surface of the main sole 5 every time the slide sole 10 moves rearward. .. Therefore, even if snow or mud adheres to the bottom surface of the main sole 5, the toe sole 6 can be bent without any trouble.

Further, in this embodiment, a fixed wire 17 is connected to the slide sole 10. The fixed wire 17 passes through the inside of the main sole 5 as shown in FIG.
It is guided upward along the rear sole 2 and connected to the tightening lever 13. And the tightening lever 13
When the tightening operation is performed, the fixed wire 17 is pulled,
The slide sole 10 is pulled backward, so that the slide sole 10 cannot slide forward. This has the advantage that the tow shell 4 can be prevented from being accidentally bent when the tightening lever 13 is tightened and the ski shoe is in the downhill state.

Of course, even if such a fixing wire 17 is not provided, when the ski shoe is mounted on the ski binding, the binding presses the upper part of the ski boot and the upper part of the rear part of the ski boot, so that there is no problem. .. Further, the bending of the toe shell 4 with respect to the instep shell 3 at the time of downhill does not cause the ski boot to be accidentally detached from the binding. Therefore, in terms of safety, it is no different from conventional ski boots.

When the toe sole 6 and the toe shell 4 are bendable with respect to the main sole 5 and the instep shell 3 as described above, walking is very easy. Especially when climbing stairs or a steep slope, the toe sole 6 bends and
The entire bottom surface of the ground touches the ground, making it very easy for stairs to rise. Therefore, even a beginner or a woman can walk safely without slipping.

More preferably, in the removable inner boot 15 (see FIG. 1) provided in the shell, it is preferable that the upper part and the toe part are easily bent. That way, shell 3 and toe shell 4
The inner boots are easily bent in accordance with the bending of the skis, and the ski boots can be made easier to walk. FIG. 6 is a perspective view of a tip portion of a ski boot according to another embodiment of the present invention. A feature of the embodiment shown in FIG. 6 is that a stopper mechanism different from that using the above-mentioned fixed wire 17 is provided in order to prevent the instep shell 3 and the toe shell 4 from bending.

More specifically, an operating lever 31 is provided at the top end of the upper shell 3. This operation lever 31 is, for example, 90 ° as shown by an arrow A3.
A lever that rotates to move the first position and 90
It can take a second position which is rotated. Then, in the first position, the instep shell 3 and the toe shell 4 are locked so that they cannot bend, and in the second position, the instep shell 3 and the toe shell 4 are unlocked so that they can freely bend.

Next, the lock mechanism connected to the operation lever 31 will be described with reference to FIG. As shown in FIG. 7, a pair of remote control wire members 32 are connected to the operation lever 31, and a stop piece 33 is provided at the tip of each wire member 32. This stop piece 33
Can be displaced in the direction of arrow A4 by the wire member 32.

On the other hand, an engaging recess 34 is formed at the connecting portion of the toe arm 28 and the main arm 29 in a state where the instep shell 3 and the toe shell 4 are not bent. The engagement recess 34 is formed by closing the gap when the instep shell 3 and the toe shell 4 are bent and the toe arm 28 and the main arm 27 rotate about the hinge pin 7.

The above-mentioned stop piece 33 is displaced between a state where it is engaged with this engagement recess 34 and a state where it is not engaged. Therefore, when the operating lever 31 is set to the lock position (first position), the wire member 32 pushes the stopper piece 33 according to the operation of the operating lever 31, and the stopper piece 33 engages with the engaging recess 34. In this state, since the toe arm 28 and the main arm 29 cannot rotate so as to close the gap of the engagement recess 34, the instep shell 3 and the toe shell 4 are reliably prevented from bending.

On the other hand, if the operating lever 31 is set to the unlocked open position (second position), the wire member 32 disengages the stopper 33 from the engaging recess 34, and the toe arm 2
Since the 8 and the main arm 29 are in a state where they can freely rotate about the hinge pin 7, the instep shell 3 and the toe shell 4 are bendable. FIG. 8 is a perspective view of a tip portion of a ski boot according to still another embodiment of the present invention.
In this embodiment, a button switch 35 having a lock mechanism is incorporated in the hinge pin 7. When the button switch 35 is pressed once, it is in a state of preventing the instep shell 3 and the toe shell 4 from bending, and when it is pressed once more, it is in the original state and is in a state of not preventing the instep shell 3 and the toe shell 4 from bending. ..

FIG. 9 is a diagram showing an example of the mechanism of such a button switch. An engagement protrusion 36 is attached to the button switch 35. When the button switch 35 is pressed once, the engagement protrusion 36 engages with the engagement recess 34 formed by the toe arm 28 and the main arm 29. On the other hand, when the button switch 35 returns to the original state, the engagement protrusion 36 can be disengaged from the engagement recess 34. Therefore, if the button switch 35 is pressed once and brought into the pushed-in state, the instep shell 3 and the toe shell 4 are
Is in a non-flexible state, and when the button switch 35 is pressed again to return it to the original state, the instep shell 3 and the toe shell 4 are in a bendable state.

The mechanism in which the button switch 35 is depressed by pressing once and returned by pushing it again can be realized if the button switch 35 is provided with a known spring mechanism or the like (not shown). .. In the above embodiments, the rear entry type ski boot was taken up and an example was explained focusing on the bending structure of the toe sole and the main sole, but the present invention is not limited to the above embodiments.

For example, the present invention is applicable not only to rear entry type ski shoes but also to so-called front buckle type ski shoes. Further, the present invention is
Not only for skis but also for snowboard shoes, especially so-called hard type snowboard shoes.
