Description

The present invention relates to a rear insertion type (rear entry type) ski boot.

Ski boots are already known which include a lower shell (shoe body) fitted with a two-part torso surrounding the lower leg of the skier. The rear portion of the torso is tiltable rearward so that the torso is sufficiently open to allow the skier to insert his or her foot into the shoe from the rear of the shoe about the lower transverse axis. Hinged to the bottom. Such ski boots include a flexible member such as a wire for clamping the front and rear portions of the trunk to each other to close and tighten the lower leg of the skier. A separate flexible member for internal foot tightening engages the interior of the shoe and pushes the foot down as well as backward as it passes over the skier's ankle and pulls. As described above, the flexible member for tightening the inner foot is "pretre court de t
Secure the tightening of the foot in an area called "alon)".

In a known rear-insertion type ski boot as described in Pinzhou Patent No. 0053340, the two flexible members for lower leg tightening and internal foot tightening are on the outside of the shoe, and
It is connected to the operation mechanism attached to the back of the rear part of the body,
Once the foot is inserted into the shoe, simultaneous tension is exerted on the two tightening members. Therefore, by acting a single pivoting lever, the circumference of the heel (p
In the rimtre court de talon) area, lower leg tightening and internal foot tightening are performed simultaneously. For this reason, known ski boots can only be used for full tightening or full release. By the way, in order to increase the comfort of the skier, it is clear that one of the tightening members can be tightened while the other is loosened.

Accordingly, the present invention relates to improving a ski boot of the type described above, and in particular to the use of such a ski boot by allowing two flexible members to be placed in tension with each other as needed. The purpose is to improve the conditions.

To achieve this object, the rear-insertion type ski boot of the present invention has a lower shell (shoe body) having a torso portion, which includes a front portion and a rear portion, which surrounds a lower leg of a skier, mounted thereon. And (the rear portion of the torso is hinged to the lower portion of the shoe body about the lower transverse axis); the lower leg is clamped to clamp the front and rear portions of the torso together. One flexible member; around the heel (primtre court de talo
n) with a second flexible member that clamps the foot within the shoe in the area (which member engages on the inside of the shoe and pushes the foot down and aft past the skier's ankle); And attached to the rear surface of the rear portion of the body,
Means for tensioning the two tightening flexible members, the means provided for tensioning the two tightening flexible members being arranged in a vertical relationship relative to one another on the rear portion of the body. And two independent operating levers hinged about at least one transverse axis and to which each of the tightening flexible members is connected.

The two operating levers may be hinged about a single transverse axis, or in addition, they may be hinged respectively about two separate axes arranged one above the other.

According to the arrangement of the present invention, it is possible to release only the upper pivot lever and loosen the single tightening member connected to the lever. The lower lever remains fixed in the tightening position.

The upper and lower pivot levers can each be connected to a flexible member which ensures internal foot and leg lower leg tightening in the area of the prime court de talon, respectively. In this case, the release of the single upper operating lever has the effect of loosening only the internal foot tightening. This arrangement is particularly advantageous in that it allows skiers to tighten their feet before the start of the competition, which improves blood circulation and comfort in the feet. Moreover, the ski boot is in a state of being properly held on the lower leg of the skier as a whole by the tension applied to the tightening member at the lower leg.

According to a variant of the invention, the upper and lower actuating levers are respectively connected to a flexible member to ensure the tightening of the lower leg and the internal foot tightening in the area of the rimtre court de talon. To In this case, the upper operating lever ensures only the release of the lower leg. Therefore, the skier can walk with the torso of the shoe open, and the foot of the skier is kept fixed inside the shoe because the internal tightening members are always in tension.

Hereinafter, although various embodiments of the present invention will be described with reference to the accompanying drawings, these embodiments are presented only as examples and do not limit the scope of the present invention.

The ski boot shown in FIGS. 1 to 3 is of a rear-insertion type, and is usually a trunk composed of the lower parts 1 and 2 of the shoe body (shell) (that is, the front part 3 and the rear part 4). Including part 2. The rear part 4 of the torso 2 is hinged on the lower part of the shoe body about a lower horizontal transverse axis 5. Further, the ski shoe 1 is provided with inner shoes (inner boots) 6 in order to ensure comfort, and the feet of the skier enter therein.

The ski boot shown in FIG. 1 also comprises two elastic flexible members, such as wires, namely a wire 7 for tightening the lower leg and a wire for internally tightening the foot in the area around the heel of the heel. including.

According to the invention, the tension of the tightening wires 7 and 8 is 2
This is done by applying action to the pivoting operation levers 9 and 10 of. This pivot control lever is shown in Figs.
In the non-limiting embodiment shown, hinged about one common horizontal transverse axis 11. The shaft 11 is carried on a bearing 12 which is fixed in the upper area of the rear face 4a of the rear part 4 of the body. If desired, the bearing 12 can be vertically adjusted and, for this purpose, can slide in a vertical window (slot) 13 provided in the rear surface 4a.

In the embodiment shown in FIG. 1, the upper operating lever 9 is connected to the internal foot tightening wire, while the lower operating lever 10 is connected.
Is connected to the lower leg tightening wire 7. However, this arrangement may be reversed, as will become apparent later.

The internal leg tightening wire 8 is fixed to a nut 14 mounted so as to slide along the upper lever 9. The nut
14 engages a threaded shaft 15 which extends longitudinally on the lever 9 and whose outer end terminates in a tensioning button 16. This button 16 therefore makes it possible to change the position of the sliding nut 14 (and thus the tension of the internal foot-tightening wire 8). As it goes away from the nut 14, the wire 8 forms a loop 8a, which is provided on both sides of the window 13 in the upper area of the rear surface 4a and which has two holes forming a turning portion. Pass 17 This hole is located above the hinge coupling shaft 11. This wire 8 then extends downwards from both sides of the shoe in the interior of the rear part 4, after which the tightening stress distribution plate 18 is passed so that it passes above the instep where it is accommodated. It extends upward.

The lower leg tightening wire 7 is itself a lower pivot lever.
A loop 7a that is hooked at the lower end of 10 is formed. The loop
The two linear portions of 7a extend upward between two parallel and almost vertical side ridges 19 that are integral with the back surface 4a, and are areas where the window 13 and the bearing 12 are provided. Extend along. Then, the two linear portions of the loop 7a of the wire 7 are directed to the outside of the shoe in a substantially horizontal direction while passing through the hole 21 which is provided in the vertical ridge 19 and constitutes the turning portion of the wire. get out. This hole 21 is the hinge coupling axis 11.
Above and at approximately the same height as the hole 17 through which the wire traverses. The ends of the two linear parts of the wire 7 are connected in an adjustable position with a hooking member provided in the upper area of the front part 3 of the body 2.

The upper lever 9 and the lower lever at the full tightening position of the shoe
Both of 10 are pressed downward against the lower area of the back surface 4a. As shown in FIG. 2, the lower lever 10 has a rear surface 4a.
The upper lever 9 is pressed against the lower lever 10.

For this purpose, the lower lever 10 is preferably formed with a hollow central part, in which the upper lever 9 is stowed in a fixed or full clamping position. In this fixed position, lever 9 and
Both 10 apply tension to both tightening wires 7 and 8. This tensile strength is adjustable. That is, the tension applied to the internal tightening wire 8 can be adjusted by the button 16 that moves the nut 14, while the tension applied to the lower leg tightening wire 7 is the position of the hooking member provided on the front portion 3 of the trunk. Can be adjusted by selecting a suitable method.

The pivot levers 9 and 10 are hinged about a common shaft 11 so as to form a kind of knuckle mechanism. In other words, looking at the upper holes 17 and 21, which constitute the turning portions of the respective wires 8 and 7, and the hinge coupling transverse axis 11 common to the operating levers 9 and 10, the lower lever is seen.
As for 10, the lower end 10a of the lever 10 to which the wire 7 is connected in the fixed position, as shown in FIG.
Is below the plane P that passes through the hole 21 forming the turning portion of the wire 7 and the hinge coupling axis 11. Therefore, the tension of the wire 7 causes the wire to move to the lever.
The restoring stress (arrow f) exerted on the lower end of 10 tends to keep the lever fixed to the back surface 4a. That is,
The lever 10 is kept closed in the fixed position. The same applies to the upper lever 9. That is, in the fixed position, the nut 14 to which the wire 8 is connected
Is also below the plane P that substantially passes through the hole 17 forming the turning portion and the common hinge connecting axis (pivot) 11.

The holes 17 forming the turning portions of the wires 7 and 8 and
Since 21 is located well above the common pivot 11 of both levers 9 and 10, the downward pivoting of both levers increases the distance between holes 17 and 21 and the movable ends of levers 9 and 10, ie , When the levers 9 and 10 are in the plane P, represented as the maximum distance traveled. Therefore, the same applies to the tension applied to the wires 7 and 8 by the levers 9 and 10.

In order to release the tightening of the shoe in this overall construction, it is sufficient to pivot both levers 9 and 10 counterclockwise about the common axis 11. Once the wires 7 and 8 have passed past the equilibrium position defined by the plane P passing through the hinge connecting axis 11, they are loosened and pivoted towards the height of the levers 9 and 10. become able to. The overall tightening of the shoe, namely the lower leg tightening and the inner foot tightening, directs the two levers 9 and 10 downwards to a fixed position in which the levers are kept pressed against the lower area of the back surface 4a. Pivot with your hands.

The ski boot according to the invention offers the advantage that, in addition to the simultaneous tightening of the lower leg and the foot, it is possible to perform only the tightening of the foot to release the lower leg. In fact, it can be seen from FIG. 2 that the lower lever 10 can be held in a fixed position. That is, in the fixed position the lever 10 is pressed against the lower area of the back surface 4a and, conversely, only the upper lever 9 is pivoted upwards (ie counterclockwise), which causes the foot Only secure the tightening release.

The present invention also provides one advantage for athletes. In other words, before the start of the competition, the athlete can keep his or her feet in a non-tightened state, so that the blood circulation and comfort of the foot can be ensured while the shoe is held tightly against the lower leg. can do.

FIG. 4 shows a modification of the present invention. According to this, the upper lever 9 is connected to the wire 7 to ensure tightening of the lower leg, while the lower lever 10 is connected to the wire 8 to ensure internal foot tightening. In this case, only the foot can be held by the wire 8. That is, while holding the lower lever 10 in the fixed position with respect to the back surface 4a, the upper lever 9 is released in the release position to loosen the lower leg tightening wire 7. In this position, the trunk 2 is open so that the skier can walk comfortably and the wire 8 is held tight so that the shoe always holds its foot.

FIG. 5 shows another modification of the present invention. In this embodiment, the upper lever 9 and the lower lever 10 are each arranged in a vertical relationship with respect to each other and mounted on a support member 24 fixed to the rear surface 4a of the rear part 4 of the torso 4 on separate horizontal traverses. It is hinged about axes 22 and 23. Fifth
In the figure, the lower lever 10 is in a fixed position, in this position it is pressed and held against the rear face 4a, and in this position the wire 7 ensures a tight tightening of the lower leg of the skier.
Apply tension to. The upper lever 9 itself is released from the restraint, and is in a position inclined upward in the figure. In this position the wire 8 is loosened and the skier's foot is not tightened in the shoe.
