Abstract

PURPOSE: To easily put on a ski boot by sufficiently inclining a rear single flat part externally without preventing the turning motion of a boot leg con nected to a shell in inserting the boot. CONSTITUTION: For putting on a boot, a boot shell 2 is provided to determine the rear opening thereof, together with a hinged boot leg 15 connected to the boot shell 2 continuously in such a state as superposed on a vamp, and cutout parts 7 and 18 formed at the back of the boot leg 15. Furthermore, the rear opening of the boot shell 2 is movably closed with a single flat part 25 in such a state as rotatable for the boot shell 2. In this case, the single flat part 25 is hinge connected to the boot leg 15 in a zone different from the zone of the boot leg 15 hinged to the boot shell 2. According to this construction, the boot can be easily put on.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a boot shell portion that defines a rear opening for wearing a boot, and a boot shell portion that is continuous with the instep portion of the foot in an overlapping relationship. The boot leg portion (shank portion) is hingedly connected to the boot shell portion, and the notch portion is formed at the rear of the boot leg, and the rear opening of the boot shell portion is connected to the boot shell portion. The present invention relates to a rear entry ski boot movably sealed by a flap in pivoting relation to the shell.

(Prior Art) Ski boots of the type into which the foot is inserted from the rear end or the type of ski boots that are inserted at the rear have been widely accepted in the market. This is because the ski boots described above are easy to put on and take off, and the tightening strength can be adjusted more easily than other types.

Such ski boots usually have a shell portion of fixed volume. Within this shell part, the part intended to accommodate the foot is constructed as a fully enclosed monolithic container. The shell portion also has a rear flap and a bootleg portion hingedly connected thereto.

In the prior art, as related to the applicant's product,
The sole is placed either by the same set of hinge pins provided for the boot leg or, depending on the choice, slightly behind the front, but in any case by a pair of hinge pins attached to the shell. is hingedly connected to the shell part.

The disadvantage of the frontal arrangement for attaching the flap to the shell is that the outward tilting movement when opening the flap obstructs the bottom edge of the flap, the so-called "heel" of the shell.
There are some restrictions depending on the department. In fact, only this design allows one sole to partially tilt backwards when inserting the innerboot, and limiting the outward tilting movement is important when inserting the foot into the innerboot. Obviously it's a hindrance.

A rearward arrangement with a flap attached to the shell part with separate hinge pin groups partially overcomes the above-mentioned disadvantages. However, such a design hinders the freedom of swing of the boot leg relative to the shell because the center portions of the pivot axes of the boot leg and sole are different.

These problems are accompanied by further disadvantages common to rear-entry ski boots consisting of a fixed-volume shell, such as those commonly employed.

Here, the volumetrically fixed shell part uses a connection or compression means that provides a relatively low degree of integration of the foot into the shell part to secure the foot. Note that a void or low pressure area is provided between the foot and the shell portion to allow movement of the foot within the inner boot.

The problem to be solved by the present invention is to provide a rear sole with a structure that allows the rear sole to be sufficiently tilted outward without hindering the pivoting movement of the boot leg connected to the shell when inserting the boot. An object of the present invention is to provide an insert-type ski boot.

[Structure of the Invention] (Means for Solving the Problems) The present invention for solving the above problems includes a boot shell portion defining a rear opening for wearing one boot, and a boot shell portion of the boot shell portion. One boot leg part (shin part) connected in a hinged manner to the boot shell part in a continuous manner overlapping with the instep part of the first foot, and a notch formed at the rear of the boot leg part. a rear opening of the boot shell portion is movably sealed by a flap in pivoting relation to the boot shell portion; The boot leg portion may be hingedly connected to a region different from the aR region hinged to the boot shell portion.

BRIEF DESCRIPTION OF THE DRAWINGS Aspects and advantages of the present ski boot will be more clearly understood from the following detailed description of preferred and non-limiting embodiments, which may be read, without limitation, in conjunction with the accompanying drawings, in which: FIG.

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

As shown in FIG. 1, which is an overall view of a rear-insertion type ski boot which is an embodiment of the present invention, the ski boot 1 is made up of a variable volume shell portion 2 (1"It), and is equipped with conventional levers, etc. The middle portion (back) '3 is not completely enclosed by the two overlapping tongue portions 3a, 3b which can be tightened to a maximum degree by operating the tightening means 4.

``--The configuration described above provides for the construction of shell sections in the assembled state by varying the volume of shell section 2 so as to secure the ski boot to the skier's foot more effectively than would be provided by a fixed volume boot shell. Together with the inner shoe interposed between 2 and the foot inserted into the ski boot 1, this allows the shell part 2 to be brought into a tight fit.

The shell part 2 is designed so that the foot can actually be inserted into the ski boot 1, representing the characteristics of a rear-insertion type ski boot.
It is made elastically deformable by providing a slit section 6 and extends upward within an instep section (middle part of the foot) 5 in which a notch section 7 is formed at the rear.

In the so-called heel region of the shell part 2, the shell part 2
The shaped body 10 lifted from the outer wall of the notch 7
is formed between the bottom edge of the boot and the heel 9 of the boot.

As shown in FIG. 3, a detailed enlarged partial perspective view indicated by arrow ■° in FIG. 1, two slots 11 are shown.
are formed symmetrically within the instep portion 5 of the shell portion 2, the function of which will be described later.

Returning to FIG. 1, the boot leg part (shin part) 15 is hingedly connected to the opposite sides of the shell part 2 by two hinge pins 16 in the so-called ankle region.

The boot leg part 15 is wrapped around the instep part 5, and the rear notch part 7 forms an additional notch part 18! j, open your mouth so that you can see it.

A respective slot 20 is formed on each side of the boot leg part 15 which is arranged to align properly with the slot 11 in the shell part 2. Regent 21 fits through the pair of slots 11.20. Here, the bootleg part 15 is firmly oriented 11 to the side of the instep part 5 of the shell part 2, with a limited degree of freedom in terms of swing compared to a rearward arrangement.

As shown in FIG. 2, which is a detailed enlarged perspective view of a portion indicated by arrow H in FIG. Two bracket formations, designated 22, are provided at the base of the notch 18.

Between the open ends 22a is a flap 25 with a protruding end for covering the opening defined by the notch 7.18.
A hinge pin 24 is placed for the purpose.

The two bracket formations 22, together with the shaped body 10 used as an adjacent member, also serve as a stop for the rearward pivoting movement of the bootleg part 15 on the shell part 2.

The hinge pin 24 is fitted into a plastic material 14 by pressure fitting in its corresponding socket 24a or into a plastic material 14 in which the boot leg part 15 is shaped to provide additional pivot support for the sole part 25. The connection between the bracket formations 22 provides a secure connection between the bracket formations 22, and also serves as a mutual connection between the bracket formations 22, which is effective in stiffening the rear end of the boot leg portion 15.

Returning to FIG. 1, two small bendable straps, indicated at 26, extend across the notch 18 into the open section, and at the open ends of the straps 26 rest against the buttleg section 15 on the front side. The corresponding hook is the ring 29 that is engaged with the part 30.
It has conventional tightening lever means 28 with.

The strap 26 is integrally formed on the side wall of the boot leg 15 or is otherwise attached to the same.

The flap 25 has an enlarged portion 31 penetrated by a clearance hole 32 into which the hinge pin 24 is inserted in loosely mated relation to its bottom portion. Said palm 25 terminates at the opposite end in the form of a plate adapted to provide support (commonly referred to in the special field as a "damage") to the skier's calf.

Said flanges 25 form a rear seal for the boot 1, with a closed portion resting against the shell part 2 and the boot leg part 15 at the notch 7.18, and approximately 90 mm towards the rear.
can be swung between the opening portion and the tilted opening portion.

In the closed part, the sole part 25 is held firmly against the shell part 2 and the boot leg part 15 by the strap 26.

In order to put on the ski boots 1, the tightening lever means 28 is moved so that both straps 26 are released, so that each hook is connected to the part 3.
0 and is also opened so that the lever clamping part 4 can extend the shell part 2 with the upper part 3 to its maximum volume state.

The sole 25 is therefore tilted rearwardly relative to the boot leg 15 around the hinge pin 24, thereby uncovering the opening defined by the notch 7.18.

Even in the above-mentioned stage of opening the band 26 and the respective fastening means, the boot leg part 15 remains sealed against the shell part 2 by means of the provided rivets 21. Therefore, the movement to put on the ski boots 1 is not hindered.

After putting on the boots 1, the sole portion 25 is returned to the position adjacent to the shell portion 2 due to the presence of the foot inside the boot 1, and the sole portion 25 is operated by the strap portion 26 and the corresponding lever tightening portion. It is completed by manually re-engaging 28.

The shell part 2 is tightened to the foot by manipulating the tightening means 4 and the boot leg part 15 via its corresponding means 28.

In use, the boot leg portion 15 together with the sole portion 25 can swing about the hinge pin 16.

This swinging movement is limited by the amount of play provided by the slot 11.20 and the bracket formation 22 adjacent the feature 10.

The main advantage of the ski boots of this embodiment is that the ability to tilt the sole over the rear, which opens fully to the rear, facilitates the operation of putting on the boots; additional advantages include:
The variable volume shell part 2 can be used to provide improved control of the ski by more effectively securing the foot within the ski boot.

Furthermore, by holding the boot leg part 15 tightly fastened to the side of the shell part 2 via the rivets 21, it is possible to prevent the boot leg from being fastened even if the boot is not fastened. , and a higher degree of freedom for movement is achieved.

Therefore, when inserting the boot portion, the rear heel portion can be sufficiently tilted outward without interfering with the pivoting movement of the boot leg portion connected to the shell portion.

This is achieved by the sole being hingedly connected to the boot leg in an area different from the area hingedly connecting the boot leg to the shell, advantageously the boot shell having a variable volume. However, rather than being completely enclosed, the tightening means are provided in such a way that the tightening portion of the shell portion can be individually adjusted.

The present invention is not limited to the above-described embodiments, but can be implemented in any appropriate manner by making appropriate design changes.

[Effects of the Invention] As explained above, according to the present invention, the boot shell portion defining the rear opening for wearing the boots overlaps with the instep portion of the boot shell. one boot leg part (shank part) that is hingedly connected to the boot shell part and one notch part formed at the rear of the boot leg part; a rear opening of the boot shell portion is movably sealed in pivoting relation to the boot shell portion by a flap, the flap being an area in which the boot leg portion is hinged to the boot shell portion; The rear heel is hingedly connected to the boot leg in a different area so that when inserting the boot, the rear heel can be tilted sufficiently outwardly without impeding the pivoting movement of the boot leg connecting to the shell. You can do it.
