Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is composed of (a) a shell with sole leather, (b) a rear cuff and a front cuff, and is provided in the area of the inner ankle and the outer ankle. ,
(c) a shoe upper connected to the shell by at least one pivot center pin; The present invention relates to a ski boot having a sliding surface formed therein, and (d) a lid for covering a groove formed between the edge of the front cuff of the shoe upper and the edge of the recessed part of the shell.

[Conventional technology]

In ski boots according to the prior art, the edge of the front cuff on the side in contact with the instep of the shoe can be adjusted without causing strain in the front cuff or shell of the shoe upper, no matter how the upper of the ski boot is turned. , in order to make contact with the shell without any gaps,
A sliding surface is provided for sliding the edge on the shell. This sliding surface is formed by a recess in the shell in the form of a surface of rotation about the pivot pin of the front cuff, with the aforementioned edge as a generatrix. This convex rolling surface in the instep area naturally increases the height of the instep area of the boot. This makes it particularly difficult to cover the groove formed between the edge of the front cuff of the shoe upper and the edge of the recess of the shell, depending on the inclination angle of the shoe upper. In other words, this lid is coaxial with the sliding surface provided to slide the edge of the front cuff on the side that contacts the top of the foot, thereby forming a natural saddle-like shape of the top of the foot. The result is an opposing convex swelling that is accentuated in the area of the top of the foot.

[Problem to be solved by the invention]

The object of the present invention is to improve ski boots of the type described in the opening part of this specification by using simple means so that the edge of the front cuff that contacts the instep of the foot can slide. The relatively flat profile of the ski boot, which is well adapted to the natural shape of the instep, can be maintained without giving up on forming the sliding surface of the front cuff as a rotating surface around the pivot pin of the front cuff. The purpose is to do so.

[Means to solve the problem]

The present invention involves attaching a pin parallel to the pivot center pin of the front cuff of the shoe upper and at a certain distance in front of the pivot center pin, and connecting a lid that can pivot around the pin to the shell. This solves the above problems.

[Effect]

In this way, the rotation axis for rotating the lid is
Since it is placed a certain distance in front of the pivot center pin of the front cuff of the shoe upper, the angle of inclination of the pivot course of the lid is smaller than the angle of inclination of the sliding surface for sliding the edge of the front cuff of the shoe upper. Become. Therefore, the edge of the front cuff that contacts the instep of the foot and the lid rotate around different pivot pins.
As a result of each different trajectory, the contours of the boot better match the natural shape of the top of the foot. Moreover, the ski boots can be made into relatively flat type shoes.

Compared to a lid fixed to the shell, a pivotable lid has the advantage that the lid does not interfere with the pivotability of the front cuff. In order to prevent the groove formed between the edge of the front cuff of the shoe upper and the edge of the recessed part of the shoe shell from being covered in an irregular manner by the pivotable lid, the lid is attached by the front cuff. It can also be rotated. In this way, when the upper is returned from the maximum pivoting position to the upright position, the lid follows the front cuff and reliably covers the groove, which increases in area. In order to rotate the lid along with the front cuff in this manner, a protrusion may be provided, for example, in the region of the top of the foot.

Sandwich the pivot center pin of the front cuff in between,
It is particularly preferred that the lid is connected to the front cuff on the side opposite to the side on which it is connected to the shell. This is because when the lid is connected to the front cuff like this,
This is because the lid and the front cuff have different lever arm lengths, so the lid is forced to be guided so that it can only turn at a smaller turning angle than the front cuff. Therefore, the adjustment distance of the lid with respect to the shell and the adjustment distance of the lid with respect to the front cuff can be kept to a minimum.

If a sliding seat is formed on the front cuff for sliding the edge of the lid that contacts the shoe upper, and the sliding seat is centered on the connecting pin that connects the lid to the front cuff. If the lid is formed in the form of a rotating surface, as a result of connecting the lid to the front cuff, it is possible to keep the lid in contact with the front cuff without any gaps under any rotational conditions. Become. Therefore, even though the lid and the front cuff have different pivot pins, the lid can contact both the front cuff and the shell without gaps. Moreover, this is true regardless of the turning state.

〔Example〕

Embodiments of the invention are shown in the accompanying drawings.

The ski boot shown in the drawings is mainly composed of a shell 2 having a sole leather 1 and a shoe upper 3.
The shoe upper 3 is composed of a rear cuff 4 and a front cuff 5. The rear cuff 4 can be connected to the front cuff 5 by a clamp (not shown).
This rear cuff is connected to the shell 2 by a pivot pin 6 in the region of the medial and lateral malleolus. The front cuff 5 is attached to the shell 2 by a pivot pin 7 separately from the rear cuff 4, and is supported by the sliding surface 9 of the shell 2 via the edge 8 on the side that contacts the instep of the foot. There is. This sliding surface 9 is formed by a recess 10 in the shell 2 in the form of a surface of revolution about the pivot pin 7, with the edge 8 of the front cuff 5 of the shoe upper as its generatrix. When the front cuff 5 turns around the turning center pin 7, no matter what turning state it is in,
The edge 8 is in contact with the sliding surface 9 of the shell 2. The width of the groove 12 formed between the edge 8 of the front cuff 5 of the shoe upper and the edge 11 of the recessed part 10 of the shell varies depending on the turning state of the front cuff 5 from time to time. This groove 1
In order to elastically support the front cuff 5 on the shell 2, a flexible spring 13 is fitted into the shell 2, which straddles the shell 2 in the region of the instep and is composed of two wire frames whose ends are connected to each other. It is. Further, a lid 14 is connected to the shell 2 to cover the groove 12 described above. A pin 15 for connecting the lid 14 is provided parallel to the pivot center pin 7 of the front cuff. When the ski boot is viewed in the vertical direction, the pin 15 is located in front of the pivot center pin 7, so the inclination angle of the virtual rotating surface as the movement course of the lid 14 in the region of the instep is the same as the inclination of the sliding surface 9. smaller than the corner. As a result, it is possible to adapt the contour of the ski boot well to the natural shape of the instep of the foot and to make the ski boot of a flat type.

The lid 14 rests on the one hand on a sliding seat 16 provided on the front cuff 5 and on the other hand on a sliding seat 17 provided on the shell 2. A sliding seat 17 provided on the shell 2 is formed as a rotating surface around a pin 15 for connecting the lid 14. Therefore, the contact between the lid 14 and the shell 2 is maintained even during the rotation of the lid 14.

When the front cuff 5 of the shoe upper pivots, the lid 14 is forced to follow it and continue to cover the groove 12 reliably, so that the lid 14 is not only connected to the shell but also connected to the front cuff by a connecting pin 18. It is also connected to 5. The connecting pin 18 is located on the opposite side of the pin 15 for connecting the lid 14 to the shell 2 with the pivot center pin 7 in between. By connecting the lid 14 not only to the shell but also to the front cuff 5 of the shoe upper, the pivot angle of the lid 14 with respect to the shell on the one hand and the pivot angle of the lid 14 with respect to the front cuff 5 on the other hand can be adjusted. , which is almost half of the rotation angle of the front cuff 5.
The sliding seats 16 and 17 can be made narrower accordingly. By connecting the lid 14 to the front cuff 5 of the shoe upper using the connecting pin 18 in this way,
It is also possible to form the sliding seat 16 in the form of a rotating surface about this connecting pin 18. If the sliding seat 16 is formed in this way, the edge of the lid 14 on the side that contacts the shoe instep can be brought into contact with the sliding seat 16 without any gap, regardless of the turning state of the lid 14 and the front cuff 5. It becomes possible to keep it.

The sliding seats 16 and 17 can be formed by recessing the surface of the front cuff 5 and the shell 2 from parts other than 16 and 17 by the thickness of the lid 14, so as can be easily inferred from the drawings. This results in a ski boot contour that approximately matches the natural shape of the instep.

〔effect〕

Because the ski boot of the present invention has the above-described construction, it better conforms to the natural shape of the instep of a skier's foot and is relatively flat compared to prior art ski boots.
