Description

DETAILED DESCRIPTION OF THE INVENTION A lateral guiding device for a ski boot, the front end of which has a fixed heel and the heel of which is free to move at least in the vertical direction; Please guide me in a #lol way.

This is about the Nordic skis that were created.

Various devices have already been proposed which are capable of ensuring lateral guidance of the Nordic skis relative to the skis. These devices are attached to the ski and serve to guide the lateral forces of the boot when the boot is unfolded and when the boot is set flat on the ski. This is due to longitudinal guide ribs cooperating with identically shaped grooves on the bottom of the boot to ensure that the guide, i.e.
(A one direction) The centering rib is L-shaped along the sole support area 1. Such a guide device is described in the applicant's French Patent No. 2.443.853. This guiding device, which includes a central longitudinal rib mounted on the ski, is operated with live operation to secure the guiding rib on the ski. In addition, the present invention has the drawback that the skier's feet are in an awkward position relative to the snow surface.
In addition to ensuring that the ski boots provide excellent directional guidance, the skier's feet are positioned as high as possible relative to the entire snow surface, while the feet are placed flat on the skis. It is an attempt to eliminate the above-mentioned drawbacks by establishing a particularly simple construction of the guide device, which makes it possible to maintain a C-free condition.

For this reason, this 1411 11110 directional guide device of a ski boot, in which the front end of the 1'C is fixed on the top of the Nordic ski 4 and whose bright part is free to move at least in the vertical direction, has guide ribs on the upper surface of the ski. At the same time, the bottom of the ski boot is formed with a groove that has a cross-section approximately the same as the guide rib and that gradually covers the rib as the foot is placed flat on the ski, and the upper surface of the groove. The guide rib is located at the same height as the rest of the upper surface of the ski, and on both sides, the lateral disengagement portions formed simultaneously on the llj surface and the upper surface of the ski allow the guide rib to reach its limit. There are signs that it is.

By way of non-limiting example, and with reference to the accompanying drawings,
Various embodiments of the invention are described.

Referring to Figure 1, although it is not shown in the drawing,
A Nordic ski boot 1 can be seen which is fixed at its front end to a Nordic ski 2 via all known types of excessive fastenings. The h part of this Nordic ski hei 1; is free at least in the vertical direction to allow the foot to tilt towards the MiT, as indicated by the arrow F (FIG. 1). M of this foot
The movement is performed by holding the heel and kicking it in half. Conversely, the unfolding (levelling) of the foot is carried out by placing the boot 1 flat on the ski 4.

While Nordeitsk ski boot 1 is performing the deployment movement,
1) The device according to the present disclosure, which is provided to ensure the lateral deflection of the boot before it is placed flat on the ski, is provided by means of longitudinal guide ribs. 3. The ribs of the cage are on both sides, and the upper surface 2a of the plate 2 is
and the hollowed out part in the 1911 surface force direction drilled in the vertical side surface 2b at the time of 1a1, '1-na, t-mo,, disengagement...
G'I'1 is limited by lJ4. Therefore, the upper surface 5 of the guide rib 3 is at the same height as the remaining part of the upper surface 2a of the ski.2) In fact, the upper surface 5 of the guide rib 3 is at the same height as the remaining part of the upper surface 2a of the ski j9. Although some
The width is narrower.

The ribs 3 can be obtained by SJ construction together with the anvil part of the ski, or they can be accentuated by cutting out two transverse grooves 4 in the reed, the material of which the ski is made.

In the embodiment shown in FIGS. 1 to 3, the inner rib 3 has an isosceles trapezoidal pheasant cross section. In other words, the width X1 of the front end of the flat upper surface 5 is
It is equal to the rear end width X2. In this way, this upper surface 5 has a long sword shape on a plane. Furthermore, the rib 3 is bounded on both sides by sloped flanks 6 9 which are connected to a horizontal support surface 7 passing through the eye 1] surface 2bK of the ski. These two surfaces 6 and 7 form a dihedron forming an obtuse angle to form a lateral locking station control 4.
It becomes. (III!I) The width y1 of the horizontal support surface 70 forming a part of the surface release portion 4, the height hl below the plane of the upper surface 2a of the ski, and the angle a1 of the slope 6 with respect to the vertical are The front end of the rib 3 for (c) is equal to the corresponding values yl, h2, and a2 at the rear end of the opposite rib.

As can be seen more clearly in FIG.
works together with the inner rib 3. The vertical groove 8 has approximately the same shape as the guide rib 3 in its wT concave.

In other words, it is an isosceles trapezoid. As can be seen from Figure 3, if the Nordic ski boot 1 is placed 1t' flat on the ski at the end of its deployment period, the acid
The navy blue groove 8 provided in the downward direction is the guide central rib 8.
1) It becomes like this. Incline of trapezoidal groove 8 111, 11 +
M] 8 a is one of the guide ribs while the foot is expanded into the root soil.
Around 6 the upper teeth gradually slide 17, as a result of which the centering of the boot is ensured. In this way, in the longitudinal direction and in the central part of the waterfall, at the foot of the shoe 9, there are two lateral ties 8.
79! The two side force ribs 1υ that penetrate into the removed part 4 are limited. In the row, ski boots 1vi, at the end of the foot expansion, 2
Preferably, the ski rests only by means of the lateral force ribs 10, which in this case are supported by their horizontal lower surfaces on the corresponding horizontal surfaces 7 of the two lateral anchorage releases 4. will be done. The reversal is higher than the depth 0 of the groove 8 and the height of the inner rib 3, so the base of the groove 8 is
8biq 2, above the inner rib 3 [at a distance from the river 5. This corresponds to when the cylindrical length hl or J]2 of the guide rib 3, the spacing between the top surface 5 and the horizontal support 7 becomes smaller than the depth 8 full. Furthermore, it is noted that the outer edge 100 of the rib 10 is located in the plane of the side surface 2b of the ski. With such an arrangement, the lower part of the ski sole is wider than the width of the ski. There are no words to say.

3rd Aln 1 - Variant [shows, according to which shoes]
The single face 8b of the sub-groove 8 itself is supported on the upper surface 5 of the intra-row rib 3. In this case, a gap exists between the lower surface 10 of the rib on the A1I11 side of the sole and the horizontal surface 7- of the side groove 4.・Figure 4 shows tree size 41. In another embodiment, the guide ribs 3 have a contour that tapers towards the rear. ■Instead of ICB, its trapezoidal cross section turns backward and gradually becomes smaller. From this, the upper surface 5b1 of the inner rib 3 has a nun-like shape of the cedar that converges toward the rear. In other words, its front end C (leaving width X1 is smaller than the width X2 of the rear end). On the other hand, the quotient at the front end of the rib 3 h 1 fd, the quotient h 2 at the rear end of the rib 3, and the angle of inclination a1 in the direction 6.
and a2 also take the same value.

In yet another smaller configuration shown in FIG. a2) Zuno...
The support surface 7 is no longer horizontal; on the contrary, its illumination
In other words, the height hl between the @ end of the earthen floor 5 and the front end of the support enclosure 7 is the height hl between the rear end of the upper surface 5 and the support wall 7. It is lower than the height h2 between the rear end of the surface 7 and the rear end of the surface 7.

In a further embodiment shown in FIG. 6, the guide ribs 3 also have a tapered contour as they turn backwards, and the side surfaces 6 also have a tapered contour.
The slope of J- is al=a2), and furthermore, the support surface 7 is sloped downward from the front to the rear (h2 (h2)), but its width is constant (y1=
y2).

In the further embodiment illustrated in FIG. 7, the guide ribs 3 exhibit the same features as the guide ribs in FIG.
x 1 > x 2 : y 1 = y 2; hl h2). However, the slope of the inclined side surface 6 increases from the front to the rear. In other words, al is smaller than a2. The angle a1 that separates the slope of the slope @6 defining the guide rib 3 can be varied starting from a value of 0. In this case, the inclined surface 6 is perpendicular to the support surface 7.

Another real 'ML' shown in Figure 8! In this embodiment, the upper surface 5 of the guide rib 3 has a curved surface 11 with a constant radius of curvature or a radius of curvature that varies over its entire length, and a vertical surface 12 perpendicular to the support surface 7. f
] It is connected to Shibumochi-ku 7, which has a slope that becomes lower toward the rear. Since the upper surface 5 of the inner rib 3 has a trapezoidal shape that converges rearward, the curved surface 11 is drawn by a radius of curvature, and its length increases from the front toward the drinking direction. It has become.

In another embodiment, shown in Figure 9, the horizontal upper surface 5 of the guide rib 3 is joined by a triangular flat surface 14 pointing towards the front, then by a cylindrical front σ 115, supporting surface 7 It is connected to the lead lFi plane 12 perpendicular to . The narrow surface 15
are two horizontal f) lines 15a and 1 extending in the longitudinal direction.
5b, the upper generatrix h'41 S a is common to the surface 14 and constitutes one side of the triangle formed by this surface, and the other lower longitudinal generatrix 15b is vertical. This is common to surface 12.

In another embodiment shown in FIG. 10, the guide rib 3
The upper surface 5 includes a plurality of sections having different widths from the front to the rear.

The front part of the claw 9 is composed of a wide front rectangular section 5a, a trapezoidal planar middle section 5b, and a narrow rear rectangular section 5c. Each of these sections 5' of the upper surface 5
a, 5 bs 5 c are each connected to the support surface 7 by an inclined surface 6a, 5b, .f3c with a corresponding slope.

FIG. 11 shows an embodiment of an internal rib 3 with a progressively increasing profile, i.e. a guide rib whose cross section increases from front to rear. In this case, the width X1 at the front end of the horizontal upper surface 5 is narrower than the width X2 at the rear end. This leaner arrangement is awkwardly reversed to that shown in FIGS. 1 and 4.

Similarly, all of the embodiments of Figures 5.6.7.8.9.10 can be reversed. In some cases, the front and rear parts may be swapped, or vice versa.

FIG. 12 shows that the guide rib 3 can extend simply over a short area A of the ski, or over a longer area B, or over the entire length C of the ski. It shows. Such a 7i knee width should be sufficient to allow one person to change the ski boot for different sizes and 1B.
