Abstract

PURPOSE: To provide a skiing boot which is easy to put on, put off, and at the same time, to enable a tongue to be exchangeable by using a fitting device to allow a translatory relative movement between the tongue and the outer casing by depending upon a 90 deg. movement of the tongue against the outer casing of the boot. CONSTITUTION: When this boot is closed, the both upper faces of link parts 32 and 34 are positioned to be on the same face, and a protuberance 74 of a tongue 14 is stored in a groove 66 of the second link part 34. When a bending movement is executed by inclining a shank bone forward, the tongue 14 is turned forward from the closing position to the opening position in the direction of the arrow mark A centering on the axis line 60 to put off the ski boot. Putting on and off the boot can be easily executed by turning the tongue 40 by 90 deg.. The tongue 40 can be easily disassembled by slightly bending the elastic hook 68 in the direction of the arrow mark C and pulling the tongue 14 rearward, i.e., upward, during opening of the ski boot.

2. Description of the Related Art Such a ski boot is described in European Patent 0 439 759 and its equivalent 19
US patent application 07 / 648,05 dated January 31, 1991
No. 6 is described. "Front shoes (Vorne insteiger)"
Ski boots which are formed as and which can be closed with conventional clasps have an outer shell which also has a sole. Furthermore, the shell has at least a toe part covering the toe region, and a front shoe upper part which follows the toe part and laterally covers the instep region and the lower ankle region. There is. The front shoe upper has a vertically long opening at the top,
The opening extends from the posterior edge of the toe to along the ankle, instep and anterior side of the tibia to the edge of the shoe. The opening is wide enough to allow the ankle to be inserted for wearing ski boots. The tongue plays the role of covering this opening, which is connected at the rear edge of the toe of the shoe by means of the coupling device when the shoe is opened, i.e. when the tightening and closing device is opened. , Pivotable towards the toe region at an angle of about 45 ° so that the ankle can be inserted into the shoe, at the same time being transverse to the pivot axis or backwards away from the toe of the shoe. Sliding upwards and upwards, thus ensuring a secure fit to the foot or ankle in the longitudinal direction of the shoe. This is possible because the link bolts, which form the axis for the pivoting movement of the tongue, are slidably accommodated in the longitudinal cutouts by the lateral guide link plates.

This type of tongue fastening in known ski shoes has various drawbacks. First of all, it is difficult to attach the tongue fixing part. Especially, it is difficult to fix the link pin in the notch of the side link plate. This is because this fixing is subject to the tacking process in the finished ski boot. Secondly, such fixed tongues, as already mentioned, can only turn about 45 °, which is too low for comfortable skiing. Third, there is only a very limited amount of length adaptation when the ski boot is closed. This is because when the tightening and closing device is tightened, the tongue and, of course, the link pin are also pressed downwards, which limits the sliding of the link pin.

[0004]

DISCLOSURE OF THE INVENTION The problem underlying the present invention, which is based on the above-mentioned known technique, is that the tongue can be easily inserted and attached and is easy to carry and operate. To provide ski shoes in the same style.

[0005]

SUMMARY OF THE INVENTION According to the present invention, the above object is achieved by providing a coupling device at least approximately in the upper center of a ski boot and having an axial link mechanism with a link portion. The outer shell or tongue is firmly connected to the first link portion, and the tongue or outer shell can slide the second link portion or the outer shell body together with the second link portion in the longitudinal direction of the link portion. It is solved by being connected to.

Other advantageous configurations of the ski boot according to the invention are described in the claims 2 to 6. In the ski boot according to the invention, the coupling device for fixing the tongue to the outer shell is such that the relative pivoting movement and the relative sliding device are performed independently of each other, unlike known ski boots. It is formed and provided in the upper center. This coupling device is formed as a two-part shaft link, by means of which the link is rigidly connected to the shell or toe. The other link part is connected to the tongue or outer shell by means of a generally rigid connecting mechanism such that the relative movement takes place transversely to the axis of the link and generally in the longitudinal direction of the shoe. The above relative movement is also possible when the tightening and closing device is under tightening and the tongue is blocked against turning. This is because the coupling mechanism is hardly compressed by this. That is, the desired length can be adapted even when the shoe is closed.

The relative sliding connection with the tongue or the corresponding link of the outer shell is provided by a groove / wedge-coupling mechanism and a locking device. In this case, the link portion is provided with a groove oriented in a substantially U-shape in plan view, and a wedge body corresponding to a tongue or an outer shell.
Of course, it is also possible to provide the groove on the tongue or outer shell and the wedge on the link portion. By forming the groove / wedge-coupling mechanism in a U-shape, lateral displacement of the tongue can be completely prevented.

A positive connection with the outer shell or tongue link is a snap-fastening or locking connection or a small bolt which is provided integrally with the link-this bolt is of the outer shell or tongue. It projects from the notch and is carried out by a fixing member, for example held by an elastic toothed disc.

In a particularly advantageous construction of the ski boot according to the invention, the tongue is designed to be replaceable, so that when the tongue wears out or needs to be replaced by the user. It is possible to insert a new and other style of tongue. For this purpose, tongues of different thickness, in particular tongues of different elasticity, are used, which make it possible to adapt to the foot and thus to reach different holding bodies, for example during slalom or gliding. It will be possible. For this purpose, the coupling device is designed in such a way that the coupling, which allows relative sliding of the tongue or outer shell with the corresponding link part, is ensured by a detachable locking device. This allows the tongue or outer shell to be disengaged from the axle link, thus allowing the tongue to be separated from the other ski boot parts in any case. If the detachable bond is formed between the tongue and the corresponding link, the tongue is removed from the ski boot while the axial link is fastened to the ski boot. When the releasable bond is formed between the outer shell and the corresponding link part,
The tongue is removed from the ski boot with the axle link secured to it. The disengagement of the tongue only has the advantage that a spare tongue can be constructed at a low cost. This is because the tongue does not have a shaft link part. Furthermore, it is easy to disengage the locking device. This is because the locking device is within reach. Separation of the tongue from the other ski boots is done without any problems and no assistance is needed to do this.

The sections allowing the sliding movements of the corresponding links with the tongue or outer shell relative to each other are the parts that abut one another when the tongue or outer shell is maximally slid relative to each other. Limited by the provision of stop and counter faces. This not only avoids a large deviation between the tongue and the outer shell which is very dangerous for the user and the resulting change in conformity, but also allows the groove / wedge to be partially disengaged in such an arrangement. -The ingress of snow into the coupling mechanism is also avoided.

With proper selection of materials for the link portions, a suitable bearing device with integral rotating pins on one link portion and on the other to reduce the number of structural parts required. Can be provided.

Hereinafter, the present invention will be described in detail with reference to the embodiments illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIGS. 1 and 2, a ski shoe 2 has a sole 6
An outer shell body 4 made of a relatively rigid material integrally formed with the toe portion 8 for covering the toe region and a rear side connected to the toe portion 8 and lateral and front sides. It has an instep and a front shoe upper part 10 for covering the ankle area. The ski boot 2 further comprises a conventional rear upper part (not shown) and a conventional tightening and closing device (not shown) for tightening and closing the ski boot 2. The outer shell 4 and the front shoe upper portion 10 are provided with an elongated opening 12 on the upper side, which is shown from the posterior edge of the toe portion 8 through the central instep region and the tibial region. It extends to the edges of the ski boot, which are not open, allowing the foot to be inserted into the ski boot 2. Tongue 14 helps to cover this opening 12,
This tongue is fixed to the rear edge of the shoe toe 8 and is more flexible than the outer shell 4 at least in its longitudinal direction.

In order to secure the tongue 14 to the outer shell 4, a coupling device 30 with a two-part axial link, for example as shown in FIG. It is provided. In this case, this coupling device 30
The first link portion 32 of is fixed to the portion 33, which is rigidly fixed to the outer shell body 4 as shown in FIG. 3 or the outer shell body 4 of the outer shell body 4 as shown in FIGS. It is fixed to a part. Second link part 3 of coupling device 30
4 is fixed to a portion 35, which is rigidly fixed to the tongue 14 as shown in FIG. 3 or fixed to a part of the tongue 14 as shown in FIGS. 1 and 2.

The coupling device 30 conforms to the shape of the foot and the shape of the outer shell and is slightly bent laterally with respect to the longitudinal axis of the ski boot 2. The first link portion 32 has a central portion 36.
With a curved end face 40, which allows the second link part 34 to pivot as the second link part 34 pivots in the direction of arrow A relative to the first link part 32.
Airspace is obtained for the upper edge 42 in front of 4 (see FIG. 2).

The first link portion 32 of the coupling device 30 is arcuately formed at its front end 44 in plan view and has a notch 48 at its rear end 46. The part 5 protruding rearward on the side of the notch 48
0 is horizontal on its inner surface, which is not visible in FIGS. 1 to 3, below and in the direction of the center, is oriented transversely to the longitudinal axis of the ski boot and is open towards the center It has a notch. This notch-as will be explained in more detail below-accommodates the corresponding rotating pin of the second link portion 34.

To firmly connect the first link part 32 of the coupling device 30 with the part 33 and the shell 4, three bolts 52 are provided below this link part 32, which are oriented downwards. These bolts are housed in the parts 33 and corresponding notches 54 in the shell 4 and are held in place by a fixing device, such as a conventional, elastic toothed disc 56. . This mode of fixation has the advantage that it can be disengaged if the coupling device 30 is damaged and must be removed and replaced with a new coupling device.

The second link portion 34 of the coupling device 30 is provided with a protrusion 58 on its front surface, which protrusion fits within the notch 48 in the first link portion 32. This protrusion 5
In each of the side faces, which are not visible in FIGS. 1 to 3, of 8 there is integrally a rotary pin which is oriented horizontally and laterally with respect to the longitudinal axis of the ski boot 2 and which projects outwards. Is formed in. The rotating pin is housed in the notch described in detail above the first link portion 32. Both rotating pins define an axis 60 which forms the center of rotation of the second link portion 34 relative to the first link portion 32.

The side surface 62 and the rear surface 6 of the second link portion 34.
4 have U-shaped grooves 66 running around them. Formed in the central region of the rear surface 64 and below the groove 66 is an arched closed hook 68 with a central cut-out 69 in the second link portion 34. The upper surface of the portion of the hook 68, which is continuous with the cut-out 69 and is continuous with the cut-out 69, is formed as an inclined surface 70. Following the hook 68, another inclined surface 72 is formed in the central region of the lower surface of the front link portion 34 (see FIG. 1). The dimensions of the hook 68 are chosen in consideration of the nature of the material so that this hook is elastically deformable in the longitudinal direction.

The portion 35 (FIG. 3) and the front portion of the tongue 14 (FIGS. 1 and 2) are provided with a U-shaped projection 74 which in a wedge-shaped fashion is the second link portion 34.
It fits in the groove 66. The lower surface of the tongue 14 and the portion 35 that is continuous with the projection 74 at the rear are formed as inclined surfaces 76.

The manner of operation of the parts of the boot 2 or of the coupling device 30 described thus far is as follows. Figure 1
When the ski boot is closed, as shown in Figure 3, the upper surfaces of both link portions 32 and 34 are positioned so that the surfaces are actually equal without tilting in the direction of each other. The protrusion 74 of the tongue 14 is housed in the groove 66 of the second link portion 34.

The tongue 14 slides obliquely rearward and upward, for example, when flexion is performed by tilting the tibia forward, or in conformity with the volume of the foot or the volume of the socks. In this case, the protrusion 74 begins to slide in the groove 66. In this case, since the groove / wedge body-coupling mechanism 66, 74 is formed in a U-shape, sluggish sliding is effectively avoided.
Section B-The tongue 14 is most slidable only in this section-
The locking nose 78, which has an inclined surface 76 formed underneath it, abuts the edge of the hook 68, which acts as an opposing surface of the cut-through 69, as shown in FIG. Limited by The dimensions of the sliding portion are selected such that when the tongue 14 is in its rearmost or uppermost position, the frontmost portion of the protrusion 74 is still in the groove 66. It This prevents complete relaxation of the groove / wedge-coupling mechanism 66,74.

In order to take off the ski boot, first, after opening the tightening and closing device (not shown), the tongue 14 is moved forward from the closed position shown in FIG. 1 around the axis 60 in the direction of arrow A. It is swung to the open position shown in FIG. 2, that is, the wearing position. It can be easily put on and taken off by swiveling the tongue 14 about 90 °, unlike the tongue which in a known ski of the same type is only able to swivel 45 °. The pivoting movement of the tongue 14 does not depend on the above-mentioned translational movement of the tongue 14. 1 tongue for swiveling movement
The position of 4 in relation to the second link portion 34 plays an important role.

The tongue 14 causes the elastic hook 68 to bend somewhat in the direction of arrow C (FIG. 2) when the ski boot 2 is open and at the same time pulls the tongue 14 backwards, ie upwards. Therefore, it is possible to easily disassemble. Similarly tongue 1
It is also possible to insert 4 easily. In this case, it is not necessary to bend the hook 68. This is done by automatically sloping surfaces 70 and 76 sliding up and down.

As mentioned at the outset, the coupling device can also be constructed in a different configuration than that described in connection with FIGS. For example, it is possible to provide a locking coupling mechanism also for firmly coupling the first link portion 32 and the outer shell body 4. This makes it easier to supplement the coupling device in case of failure. The additional locking coupling mechanism is configured to allow translational relative movement between the parts to which it is coupled. This is the case when joining the tongue 14 with the second link portion as described above. This actually doubles the length fit compared to the ski boots described above. It is also possible to make the locking coupling mechanism non-sliding so that it can be conveniently carried, as in the ski boot described above.

[0026]

As described above, according to the present invention, the tongue 14 is swung by 90 ° with respect to the outer shell 4, and the translational relative movement between the tongue 14 and the outer shell 4 is dependent on this. By allowing and configuring a coupling device 30 that is easily assembled, it is comfortable to wear and can be taken off, allows for a significant length of fit in the closed condition, and is simple In this way, a ski boot is obtained which makes it possible to remove the tongue and replace it with another tongue, without the use of auxiliary means.
