H 115/2 ski boots

The invention relates to footwear in general and in particular to a ski boot of the rear accessible type which has provisions for adjusting the deflection of the boot which is generated by the force of the ankle of a skier who is in a forward leaning position.

The ski boot according to the invention has a multi-part jacket made up of two complementary parts mated together in a plane passing through a center line which extends from the front to the rear of the boot. In the union, the boot is used according to According to the invention, a slidable clamping device which extends along part of the length of a ribbed path can move to a convenient and relatively simple set up to adjust the amount of deflection in the boot.

Many of the currently available ski boots essentially have one rigid outer jacket generally made of plastic material. Inside the mantle is common a liner is arranged to act as a cushion between the coat and the foot of a skier. When a skier himself is in a forward leaning position at which point the skier's knees are generally above the boot and lying in front of it, pressure is exerted against the front part or upper leather of the boot. In general and in particular In the case of boots that have plastic sheaths, the boot is kept relatively stiff so that it is does not sag. This is particularly the case with experienced skiers and racers who have as little deflection as possible wish in the ski boot. The less sagging the boot shows, the more the ski is susceptible to the skier's feet.

ORIGlNAL INSPECTED

responsive, in which case the skis act as a continuation of the skier's feet.

In other cases, however, ski boots without sagging are not desired by less experienced skiers, as this increases convenience of the skier impaired. Likewise, they wish Skier, any device for regulating the ability to stabilize to have the skis.

Unfortunately, most ski boots do not have a light facility Adjusting the deflection in a boot. Because of the relatively stiff plastic materials used for the jacket Rather, the jacket of the boot is essentially rigid. The only means of any deflection Achievement in the boot are the adjustments made possible by the buckle closure system of a particular boot will. In this regard, however, the buckle closure systems do not serve to completely satisfy the deflection requirements of various skiers. Accordingly it is desirable to provide some other means of providing the desired deflection in the shell of a ski boot results. It is also desirable to have an adjustable deflection device to be arranged, while at the same time a boot is provided, which is relatively easy to manufacture and Unification enables.

The invention therefore relates to a ski boot that has a device for adjusting the deflection in the boot to the extent desired by a particular skier. The ski boot according to the invention not only enables the desired deflection to be achieved, but the boot additionally requires a new and improved method of making and incorporating the same.

The boot according to the invention has a substantially rigid one outer mantle, which consists of two complementary parts, wake up when the mantle is united by appropriate

409839/0274

fastening means, such as screws, connected to one another will. The two parts that make up the upper of the coat are complementary parts that run along their dividing lines be connected to each other. When the boot is assembled, the dividing lines of the jacket parts lie essentially in a vertical plane passing through a center line extending from the front to the rear of the boot. The outer mantle is completed by a rear tongue unit, which can be connected to the united sheath parts.

An adjustable clamp can be along one with flanges provided web slide which is arranged on the front of the unified shell. The clamping device can be in any a number of positions can be arranged in which Position the clamping device, securely fastened with the appropriate Effect that the jacket only allows a certain amount of deflection when the boot is in use.

The boot according to the invention can be equipped with a corresponding lining and a wax fitting system, such as the liner and fitting system of FIG U.S. Patent Application No. 216,080 dated January 7, 1972 Art. In addition, the boot according to the invention with interchangeable rear parts as described in the American patent application No. 231 967 of March 6, 1972 'type described. For the boot according to the invention, however, can also other liners can be used and the present invention can be applied to boots other than those described above from the rear accessible type, find application.

The invention therefore relates to i a ski boot having a shell which is composed of two combined with each other complementary parts, and contains the means by which a skier may alter the deflection of the ski boot.

The invention is described in more detail below with reference on the drawing in which shows:

Figure 1: a side view of the ski boot according to the invention, the rear portion of the boot being cut away to reveal the ribbed lower portion of the to expose a part of the jacket,

Figure 2: a tongue with a lug attached to it, the tongue at the union between the inner Wall of the jacket and the outer wall of the liner is arranged, as shown in Figures 1 and 3 is,

Figure 3: the jacket parts of the ski boot on a larger scale according to the invention, which inevitably opens in a forward inclined position of the skier whereby portions of the flanged ribs on the shell portions outwardly away from each other be pressed so that the boot can flex to the desired extent, and

FIG. 4: on a larger scale, a cross-section along the line 4-4 in FIG. 1.

In Figure 1 of the drawing, a ski boot 10 is shown with a stiff sole 12, which has a front section 14 and a rear section 16 for engagement with the ski binding. The shell 5 of the boot is preferably formed from two complementary parts 17, 18 which mate in a vertical plane 9 passing through a center line extending from the front to the rear end of the boot. The casing parts 17, 18 are fastened to one another along the sole by means of appropriate fastening means, such as screws 8, which are inserted into countersunk bores 7 in part 18 and screwed into bores 6 arranged in part 17. Each shell part is preferably shaped in such a way that the sole 12 consists of one piece, and that the bottom 22 of the shell is

409839/027 ^

Assemble the boot to support the inner lining 24 is used. The lining 24 is arranged inside the jacket 5 and lies between the united coat and the foot of a skier.

The sole 12 is spaced from the floor 22 by means of Ribs 25 connected. Air spaces 26 are provided between the ribs 25 to reduce the weight of the boot by eliminating material from the sole of the same / serving. The ribs are of sufficient strength to withstand the weight of the skier and the forces that arise act on the boot when it is worn. If desired, the weight of the boot for a particular skier to change on request, these air spaces can be filled with material to achieve the desired boot weight.

As FIGS. 1 and 4 show more clearly, the jacket part 18 has lugs 27 which are at the front and rear ends of the jacket part lie. When combining these approaches are used in corresponding grooves 28, which on the front and rear The end of the shell part 17 lie. A groove 29a is also arranged along a substantial part of the length of the jacket part 17. A corresponding one Approach 29 is along a substantial part of the M fraction part 18 and fits tightly in the groove 29a. During the union, the lugs 27 are fitted into the grooves 28 and the lug 29 is fitted into the groove 29a, after which screws 8 are used to secure the formation of the sole 12 by securing it of the shell parts 2 17,18 to complete. If desired, glue can be used to make the lugs in the grooves to cement, so that a substantially leak-free connection between the shell parts in the area of the sole 12 is provided.

When the parts 17 and 18 are connected to one another, the front ends thereof serve to form the upper leather of the T-boot. Each part has a rib 30, 31 which extends from the section of the shell part which has a rounded outline extends outside. The rib 31 has a flange 32 and the rib 31 has a flange 33. The flanges protrude from each other outwards and are essentially perpendicular to the ribs.

/. η α ο ο <ί / η *>? /.

When the jacket parts 17, 18 are united, the ribs 30, 31 against each other so that they lie essentially in the vertical plane 9 which passes through the center of the boot. A slide 34 is arranged to slide along at least a portion of the path 35 passing through the flanged provided ribs 30,31 is formed. That part of the track 35 which is closest to the toe area of the boot is used Rivets 36 or other corresponding fastening means in order to securely connect the ribs 30,31 to one another. On the opposite At the end of the track 35 a number of holes 37 are arranged at selected locations along the part of the track which is not included Rivets are provided so that the jacket is split.

The slider 34, which can slide along the track, contains a screw 38 which passes through one of the selected holes 37 can go through. The slide 34 consists of the web 60 and two legs 61, 62 which extend outward from the web. Each of the legs 61, 62 has an inwardly directed flange 63 at its outer end. The leg 61 is threaded to receive the fastening screw 38, while the leg 62 has a bore 64, the diameter of which is slightly larger than the head diameter of the screw 38. The bore 64 is aligned with the threaded bore in the leg 61.

The desired deflection properties in the boot can can be achieved by arranging the slide 34 at a special hole 37 «

When a skier wishes to change the deflection in the ski boot, the screw 38 is unscrewed and out of the hole 37 removed. The slide 34 is then moved along the path 35 to another of the holes 37. The screw 38 is back in the Hole inserted and screwed into the threaded hole in the leg 61 until the head of the screw is within the bore 64 of the Leg 62 is arranged. When the pusher 34 is near the top of the track 35, it will be the least amount allows the deflection, while the deflection in the boot will increase when the slide 34 along the path 35 against

£ 09839/0274

the toe area of the boot is moved.

If, in the manner shown in FIG. 3, pressure is applied to the lining and the jacket of the boot is exercised through the ankle of a skier, the jacket parts 17, 18 can attach Separate the ribs 30,31 along the path 35 up to the point where the ribs are firmly connected to one another by the slide .34. Therefore, if a skier wants more deflection in the boot, it is only necessary to adjust the slide 34 along the track 35 to move down to a special hole 37 into which the screw 38 is screwed to secure the slide in its To fix position »

A tongue 40 is arranged between the outer wall of the liner 24 and the inner wall of the jacket 5 in order to prevent that snow comes into contact with the lining 24 when the ribs 30, 31 are separated. The tongue 40 is preferably shaped and can be made from the same or different materials as the jacket. An extension 41 is firmly connected to the tongue 40 and protrudes outward from the lower end of the same. The approach 41 adjoins the lower edge 43 of the tongue. The outline the tongue essentially follows the outline of the jacket and the lining in the area where the tongue is inserted into the boot will.

According to FIG. 1, the tongue 40 is behind the ribs 30, 31 and arranged on the front of the liner 24, which consists of a foam liner and a wax-filled bladder. The tongue extends along part of the length of the panel 35 and protrudes at 44 slightly beyond the top of the shell.

Each of the ribs 30, 31 is recessed at 50 by at least half the thickness of the projection 41 and corresponding to the shape of the Shaped approach. When the casing parts 17, 18 are combined, the projection 41 is arranged in the recesses 50 of the ribs 30, 31 and the bore 49 is connected to the rivet bore 36 in each casing

A09839 / 027A

part aligned, whereupon a rivet or other fastener connects the approach and the shell parts with one another.

When the shell of the boot is flexed, the area exposed between the ribs is protected by the tongue 40, as shown in FIG. The tongue serves to prevent the penetration of snow between the jacket and the lining 24 into the area exposed by the opened ribs; moreover, when the boot is bent, the jacket parts at the location of the ribs 30, 31 will not rub against the lining but rather touch the front side 51 of the tongue 40.

The boot according to the invention has a device which adjusts the deflection in the boot as desired by a skier. The coat of the boot is on split a part that starts at the top of the boot and extends towards the bottom of the boot. An institution, such as slider 34, is provided to open the split shell at any of a number of selected ones To connect positions along the split part, so that when pressure is exerted on the jacket, it moves along the split separates to the point where the connecting device securely connects the split parts together.

The invention is not limited to the embodiment shown and described, for example, the various modifications can experience without departing from the scope of the invention,
