Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a ski shoe type boot which has a casing or shell and leg portions that are rotatable in the front and rear directions with respect to the shell, and which is inserted from the rear. The leg portion includes a sleeve that surrounds the anterior part of the tibia and opens to the rear, and is rotatable in an anterior-upward direction and a posterior-downward direction with respect to the sleeve, and when the boot is worn. , comprising a cover fixed to the sleeve by closure means, said sleeve having in its front region a pair of slots extending downwardly from the upper edge of said sleeve.

[Prior art and its problems]

"Boots that are inserted from the rear" require that by closing the cover the
In this case, pressure is applied to the asymmetrical tibia that is displaced laterally,
This also has the problem of compressing the leg into the central location where it assumes the X position. To compensate for this phenomenon, when a skier crouches during normal skiing motion, he or she will lower the outside edge of the ski and raise the inside edge of the ski. This is especially harmful for inexperienced skiers when making turns or turns, during snow plow movements, and especially during rotational speeds J.

[Means for solving problems]

The present invention provides a way for the leg portion and sleeve to conform to the anatomically correct position and shape of the tibia when the cover is closed. In ski boots of the above type, this purpose is achieved according to the invention by providing two (hard) flaps to hold the upper parts of the sleeve together, these flaps surrounding the upper region of the sleeve and These flaps are pivotally interconnected so that they can be adjusted or displaced in opposite directions by movement of the foot.

According to another feature of the invention, a slot is further provided in the longitudinal center of the sleeve. This additional slot is shorter and wider than the two transverse slots, so that the 211M section is in mirror image relation to the longitudinal midplane of the ski boot and allows the sleeve to be fixed even if there are some irregularities. , tibia solution! '! 2. It is made to match the geometrical shape very closely.

Advantageously, the device for holding the sleeve parts together fixes the sleeve parts in their mutual position after the cover has been closed.

Finally, it is an object of the invention to hold the sleeve parts together by providing 2 (+#) flaps which surround the upper region of the sleeve and extend from both sides of the sleeve; They are rotatably connected at their free ends.

The present invention has a casing or shell and a leg part which is rotatable in the direction of movement of the shoe about an axis perpendicular to the direction of the shoe (this is a cuff surrounding the 11j Hijikata part of the tibia). or a sleeve, and a cover mounted rotatably around an axis perpendicular to the direction of travel opposite the sleeve and connected to the sleeve of the boot by means of a closure. We provide ski boots that fit.

The sleeve is provided with a 1" throat extending downwardly from the upper edge in the central front area over its entire surface, and has 2+flit flaps displaceable in opposite directions, these flaps being pivoted or by means of guide members. They are connected and can be fixed in any position.

〔Example〕

The invention will now be explained in more detail by way of example embodiments and with reference to the drawings.

The embodiment of the present invention has an inlet at the heel end and has a casing or shell (1) and a vertical hole or leg portion (3) that is rotatable in the front and rear directions with respect to the shell. death,
In this example, a sleeve (4
), and has a cover (5) at the heel end, which cover (5) is preferably pivotally attached to said sleeve and which, in the position of use, closes the sleeve (4) by means of closure means, for example in the form of a tension belt. It is said that it can be freely combined with. The inner boot part or shoe (6) is inserted into the ski boot and has a heel part (7) which is rotatable with the cover (5).
). When the boot is worn, the cover (5) is held on the sleeve (4) by a tension heald. One end of the belt can be attached to one of the lateral walls of the leg part (3), and the other end can be adjustably fixed to the other lateral wall of the leg part (3). In conventional ski boots, the skier's leg (9), shown in cross-section in FIG. ) outside the central plane (E), but this gap is eliminated by the ski boot according to the invention.

To this end, the sleeves (4) are arranged on both sides of the longitudinal midplane (E) and spaced apart from each other with slots and throats (12).
, (13), which extend from the upper edge of the sleeve (4) over a portion of its height. They also form a section (14) as shown in the third figure, which fits the tibial axis indicated by the dash-dotted line (15) and thus compensates for the gap (11), so that the inner boot (6) - fully abuts the leg of

Flaps (18) and (18') are used to hold the section (14) and the other parts of the sleeve together during downhill riding, i.e. when the skier bends his knees; Similar to 4), it may be made of plastic material and such flaps may be made of a sleeve (
4) from the side walls (19) and (20) to Throno) (12)
and (13), for example, the iif++ flap is attached where the tightening belt is similarly attached. In this example, the flaps (18) and (18') of both legs are at the center position so that they are in a pictorial relationship with the vertical central plane, and the gap (2) is located between both flaps (18'). ) and (18'). These flaps extend along the road edge of the sleeve (4) and their free ends are connected by a guide or pivot member (21), so that when one flap is pushed up, the other -E must be directed and vice versa (see Figure 3). The rotating member (21) bridges the gap between the free ends of the two flaps (18), (18') and is pivotally connected to each of the two flaps.

Both flaps are in this example independent components connected to the sleeve (4), but these components are extruded integrally with the lateral walls (19) and (20) of the sleeve (1). Molding is also an F+J capability.

As indicated by the dashed line in FIG.
) shorter is preferable. This method provides a better fit to the internal foramen, especially if there is an irregularity in the legs.
E.

Due to the measure according to the invention, the sleeve (4) is displaced above the throat (and ankle) shown in the third figure, so that the cover (4)
5), the sleeve (4) conforms to the anatomically correct position and shape of the tibia. This position of the sleeve (4) is held by the device illustrated in Figures 746-13, so that the pivoting member (21) is fixed in this position, for example.

Upon displacement of both flaps (18) and (18'), the pressure exerted on the leg increases due to the flap moving upwards, while the pressure due to the flap moving downwards decreases. The ski is therefore uniformly loaded over its width, so that the ski can also be guided well.

In the embodiment shown in the fourth figure, two flaps (18)
and (1B') constitute an extension (3') of the leg part of the shoe, which extension (3') surrounds at least the front part of the sleeve: the flaps (18) and (1B') An inverted “Y” shaped slot allows the above extension (
3').

In the embodiment of the ski boot shown in FIG. 5, the pivot element (21) is covered by an extension (22) of the lower transverse element (23), and the lateral thrower 1-(24)
) in the pivot member (21) and in the longitudinal slot (25)
is provided on the extension member (22). A bottle (26) passes through both slots, extending from the pressure plate (26') and having a detent hole (26'') at its free end.A shaft (28)
) passes through the dot hole (26'') and the clamping means eccentrically passes through the cylindrical fork-like end of the tension lever (27), which acts as an eccentric lever.

Because the two throwers l-(24) and (25) extend perpendicularly to each other and lie suspended in the pivot member (21) and the extension member (22), these components are under tension. As long as the lever (27) is up, the flap (18)
) and (1B') can be freely displaced from each other. However, if the lever (27) is pushed towards the shoe, the pressure plate will be pulled towards the pivoting member (21) and the forked end of the lever (27) will be pushed towards the extension member (21).
2) Press/apply. Rotating member (21) and horizontal member (2
3) are fixed to each other by frictional force, and the sleeve cannot be displaced quickly.

The skier puts on the shoes, closes the cover (5) and bends the knees to assume the downhill riding position; this causes the lever (27) to be opened, i.e. pivoted away from the shoe; The sleeve can assume the position shown in the third figure. The lever (27) then moves ζ against the boot.
When pressed, the eccentricity fixes the transverse member (23) in the position taken by the legs, as described above. The skier is therefore well supported in the shoe and therefore has good guidance of the ski. As soon as the downhill run is finished, the skier can assume a more comfortable position in the shoe by releasing the lever (27).

Finally, it is also possible to omit the flaps (18) and (18') and attach the pivoting member (21) directly to the slotted sleeve. Instead of the eccentric means mentioned above,
Any other securing means may also be used.

According to figure f314, there are two flaps (18) and ([
') lie with their free ends one above the other. The end of the flap (18') in this case is provided with a slot (30) which extends upwardly from the top in a straight or curved manner. This throat is pierced or pierced by a bottle (31) which is fixed at one end to the pressure plate (32) and has an upper flap (
18) is bored or passed through a hole (34) at its free end but has a wide bend (33) at its other end.

In this embodiment, the pivot member (21) or pivot member (21a) and the transverse member (23) are replaced by slots (30) and bins (31), which slots and bins hold both flaps together. What does it do to keep the same effect?

It is also possible to achieve mutual fixation of both flaps (18) and (18') by frictional force by using a screw instead of the head (33) and screwing the knurled nand onto this screw. .

In the ski boots shown in Figures 16 to 20, the two leg flaps (18) and (18') are connected by pivot members (21) and (21a) of 2flA1, which are spaced apart from each other in the vertical direction. and the upper rotating member (21)
is arranged approximately in the vertical center of the two leg flaps (18) and (1B'). Two rotating members (21) and (
21a) is rotatably connected at both ends to the leg flaps (18) and (18'), for example by means of a bed (40).

In the gap (2), install a threaded pole l-(35) (first
8), which is fixedly riveted at its inner end to the upper coupling pivot member (21) and supports an adjustment nand (34), which is connected to the locking knob (34).
36) so as not to rotate. round toothed plate (
33) is removably attached to the adjustment pad (34) and is prevented from coming off by a collar (37) or the like. As you can see from Figures 19-20, the toothed slope (33)
is provided with a lug (38) in its T-section which extends downwardly in the longitudinal mid-plane and has an axle (35) at its left end, which axle is connected to the lower connecting pivot member (21a). It is assembled rotatably (Figs. 16-17).

The two leg flaps (18) and (18') have a gap (
2) Along each edge of the tooth profile (41)
and (41'), which correspond to and are engaged with the tooth profile of the toothed treatment (33), which will be explained in more detail below.

Before the skier inserts his or her foot into the boot, the locking knob (
36) is 6'ffJ' on threaded pol I-(35)
Tightened by J naso l- (34), toothed plate (33)
and the toothed rings 1i+ (41) and (41') are disengaged from each other.

When the skier puts his foot into Wataru's ski boots, the 17th
As shown, flaps (18) and (18') are displaced in opposite directions as the irregularity of the foot compresses the sleeve laterally. For this reason - one slot, in this case slot (13), is compressed and the other slot, in this case slot (12), is expanded.

Thus, the flap (14) formed between the slots (12) and (13) is laterally displaced and the entire boot conforms to the shape of the leg, so that the leg is firmly and comfortably supported in the shoe. be done. When the ski boots are in this position,
The locking knob (36) is rotated until the toothed plate (33) engages the two toothed rims (41) and (41'), thereby fixing the boot in the fixed position with the foot.
