Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fitting device for improving the fitting properties of ski boots, particularly rear-entry type ski boots.

[Conventional technology]

The rear entry type ski shoe consists of an outer shell made of synthetic resin, an inner boot inserted into the outer shell, a shell body that covers the outer shell from the ankle down, and
A front cuff that covers the ankle to shin area,
It is composed of three parts: the rear cuff that covers the area from the heel to the calf, and the rear cuff is provided so that it can be opened and closed rearward, so that when putting on or taking off the shoes, The rear cuff opens backwards.

[Problem that the invention seeks to solve]

Conventionally, in the case of rear-entry ski boots such as those mentioned above, the ski boot and the foot are fixed only by tightening the buckle that connects the rear cuff and the front cuff. There was a problem in that the legs in the lower part were not sufficiently fixed, resulting in a lack of fit.

SUMMARY OF THE INVENTION Therefore, the present invention aims to improve the structure of the fit in the shell body that covers the area below the ankle in a rear entry type ski boot.

[Means for solving problems]

In order to solve the above problems, this invention
A pair of flexible synthetic resin plates are fixed at their lower ends to both sides of the inner surface of the shell body, with their upper ends facing each other at the upper center of the inner surface of the shell body, and the upper ends of the pair of synthetic resin plates are are connected to each other through a pantograph mechanism so that they can be pulled together and pushed down, and an operating lever for this pantograph mechanism is provided on the outer surface of the shell body.

[Effect]

If you operate the pantograph mechanism using the above operating lever and push down while pulling the upper ends of the synthetic resin plates together, the front side from the top of the foot to the side will be pressed by the synthetic resin plate, so the foot will be firm. Fixed.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The ski shoes 1 have outer shells 2 made of synthetic resin.
and an inner boot 3 inserted into the outer shell 2.

The outer shell 2 is composed of three members: a shell body 4 that covers the area below the ankle, a front cuff 5 that covers the area from the ankle to the calf, and a rear cuff 6 that covers the area from the heel to the calf. Both lower ends of the front cuff 5 and rear cuff 6 are attached to the shell body 4 slightly below both the inner and outer ankle portions by pins 7, respectively. The rear cuff 6 is rotatably attached to the shell body 4 and can be opened and closed rearward.

A pair of flexible synthetic resin plates 8, 8' are inserted between the inner surface of the shell body 4 and the inner boot 3, and the upper ends of the pair of synthetic resin plates 8, 8' are above the inner surface of the shell body. The lower ends of the shell body 4 are fixed to both sides of the inner surface of the shell body 4 by rivets 9 so as to face each other at the center thereof. The synthetic resin plates 8, 8' are 20
This synthetic resin plate 8 is formed to have a width of about 30 mm.
A synthetic resin plate 10 may be inserted along the upper surface of the inner boot 3 between the lower surface of the inner boot 3 and the lower surface of the inner boot 3, and the pressure may be applied via the synthetic resin plate 10.

The upper ends of the pair of synthetic resin plates 8, 8' are connected via a pantograph mechanism 11 so that they can be pulled together and pushed down.

Examples of the pantograph mechanism 11 are as follows.

First, as a first example, shown in FIGS. 2 and 3, a pair of links 12,
12' are assembled in an X-shape so that they can be bent freely at the center, and the lower ends of these links 12, 12' are
Pivotally attached to the upper ends of the pair of synthetic resin plates 8, 8',
The upper ends of the links 12, 12' are rotatably supported by a pair of movable blocks 14, 14', which are screwed onto a threaded rod 13 rotatably supported on the upper central portion of the inner surface of the shell body 4, respectively. . The threaded rod 13 has threaded portions in opposite directions on the left and right, i.e.
A right-handed threaded portion and a left-handed threaded portion are provided, and blocks 14 and 14' are screwed into the right-handed threaded portion and the left-handed threaded portion, respectively. Further, one end of this threaded rod 13 is drawn out to the outer surface of the shell body 4,
An operating lever 15 is attached to the end thereof so as to be able to rise and fall freely with respect to the shell body 4. A recess 16 for accommodating the operating lever 15 is formed on the outer side of the shell body 4.

Raise the operating lever 15, and
When the screw rod 13 is rotated by holding the screw rod 5, the pair of movable blocks 14, 14', which are screwed into threaded portions of the screw rod 13 in different directions, move closer to each other or move away from each other. When the threaded rod 13 is rotated so that the movable blocks 14, 14' approach each other, the X-shaped links 12, 12' gradually move so as to overlap each other, and along with this, the synthetic resin plates 8, 8' The upper ends of are pulled together and pushed downward. In this way, the upper ends of the synthetic resin plates 8, 8' are pulled together and pushed downward, so that the entire upper surface of the foot is pressed through the inner boot 3, and the foot is firmly fixed to the shell body 4. Ru.

Next, as a second example of the pantograph mechanism 11, there is one shown in FIGS. 4 and 5. The structure of this one is as follows.

That is, as in the first example, a threaded rod 17 having threads in opposite directions on the left and right and a left-hand thread is rotatably supported in the upper center of the inner surface of the shell body 4. One end is Ciel body 4
The operating lever 1 is pulled out to the outer surface of the
8 is provided to be able to rise and fall freely with respect to the shell body 4. A fixing block 19 is fixed to the center portion of the threaded rod 17, and the upper ends of arcuate links 20, 20' are rotatably supported on the fixing block 19. The arc-shaped link 20,
The lower end of 20' is rotatably supported by the upper end of the synthetic resin plates 8, 8' via a support plate 21, respectively. The right-hand threaded portion and the left-hand threaded portion of the threaded rod 17 are as follows:
Movable blocks 22 and 22' are screwed together, respectively. Further, an arcuate through hole 23 is formed in the side surface of the arcuate links 20, 20'. On the sides of the movable blocks 22, 22',
A sliding pin 24 is provided which is slidably fitted into the through hole 23 of the links 20, 20'. In addition,
The links 20, 20' are arranged before and after the threaded rod 17.
They are provided in pairs so as to sandwich the threaded rod 17 therebetween.

In this second example, when the operating lever 18 is raised and the threaded rod 17 is rotated by holding the operating lever 18, a pair of movable blocks 22, 22 which are screwed into threaded portions of the threaded rod 17 in different directions are connected to each other. ′ become closer to each other or move away from each other. When the threaded rod 17 is rotated so that the movable blocks 22, 22' approach each other, the sliding pins 24 of the movable blocks 22, 22' move upward within the through holes 23 of the links 20, 20'. Along with this, link 2
0 and 20' use the upper end as a rotation axis and the lower end thereof gradually moves inward. As a result, the synthetic resin plate 8,
Since the upper ends of the shoes 8' are pushed downward while being drawn together, the entire upper surface of the foot is pressed through the inner boot 3, and the foot is firmly fixed to the shell body 4.

In addition, in FIGS. 3 and 5, the reference numeral 25 indicates the bearing 17 of the threaded rod 13.

In the above embodiments, the fitting device is provided in the instep portion of the shell body, but the position where the fitting device is provided is not particularly limited, and it may be provided in the ankle portion.

〔effect〕

As described above, according to the present invention, in a rear-entry type ski boot, the foot inside the shell body is firmly fixed from the top surface to the entire side surface thereof, so that the foot is prevented from shifting in the left-right direction inside the shell body. This has the effect of significantly improving the fit.
