Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sealing member for a gap extending transversely to the longitudinal axis of the ski boot shell and located between the vamp of the shell and the waistband carrying the closure member. can be inserted into said gap and can be firmly connected to one part of the shell, in particular to the vagina, while being freely located with respect to other parts, in particular to the vagina, and to the vagina. Relates to a sealing member which is adapted to be uncoupled. The gap between the toe and the waistband is directly impinged by the snow and is therefore the first to allow snow to enter the boot. To seal the gap, conventional practice has been to use a spongy material with open pores and to glue this material to the shell. However, movement between the loin strap and the nail strap is unavoidable. Moisture therefore penetrates into the spongy material, and the movement between the waist and toe caps creates a pumping action that facilitates water permeation. Therefore, the effectiveness of the sealing member as described above cannot be guaranteed.

In order to prevent the opening of the spongy seal from being exposed on the front side, it has previously been proposed to fold the spongy material over itself and to glue the folds together. Although the folding allows almost the entire closure envelope of the cancellous portion to reach the front surface, the elasticity of the sealing member is reduced due to the large compressive forces that occur during bending. Due to the reduced elasticity, the skin at this point becomes more prone to breakage, and such a sealing element therefore easily loses its effectiveness.

The object of the invention is to form a perfect seal between the toe and the quarter at the point where snow first strikes, characterized in that the seal is made of an elastic rubber material and has on its free surface a number of ribs extending transversely to the longitudinal axis of the shell. The ribs form a lip which is pressed against the other part, i.e. the quarter, and is therefore deformed, thereby providing a reliable seal. The toe has a smooth surface, so that the seal is advantageously firmly attached to it by gluing or welding. The seal must be provided on both quarters which are superimposed on one another. To achieve this seal, it is desirable to form the ribs appropriately so that the surface of the seal formed by the ribs comes into contact with the quarter. Because the ribs are deformable, the seal can be made of a non-porous elastomeric material, in particular rubber or thermoplastic rubber. However, the seal can also be made of a spongy material with fine closed pores. In this way the deformability of the ribs is improved and the sealing contact pressure of the ribs is ensured.
In both cases, however, when formed to be microporous, the sealing material itself becomes impermeable to moisture due to the impermeability of the obturator tissue.

According to a preferred embodiment of the present invention, the combs of the ribs have an arched shape when viewed from the front, and the height of the sealing member decreases toward the ends on both sides of the longitudinal axis of the shell. is being used. Therefore, it conforms well to the shape of the gap between the nail strap and the waist strap, and the deformation of the sealing part in all directions is performed almost uniformly. If the cross section of the rib decreases toward the rib comb and an acute angle is formed at the rib comb, the tapered rib in one cross section can be easily deformed and have excellent sealing properties. This is particularly advantageous.

One rib, especially the central rib, can be higher than the other ribs. In this way, even when the clamp is not completely closed or is opened, as is often the case when walking, the sealing member is improved because the sealing is performed by at least the higher rib. It can be seen that

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, numeral 1 indicates the toe leather of the ski shoe shell. 2 and 3 represent both waist straps, which are normally formed integrally with the nail strap 1. Reference numeral 4 denotes a closing member formed by a clamp, to which the waist leathers 2 and 3 are securely fastened.

A gap 5 is left between the nail strap 1 and both waist straps 2 and 3. The right waistband 3 is superimposed on the left waistband 2 and defines a stepped upper limit of the gap 5;
This makes it difficult to seal this gap.
A sealing element 6 shown in FIGS. 2 to 4 is therefore inserted into this gap, which sealing element is formed, for example, of solid rubber, thermoplastic rubber or rubber with fine closed pores. has been done. The underside 7 is flat in the undeformed state of the sealing member 6.
This lower side 7 is glued or welded to the vamp 1. The upper side 8 has ribs 10, 11 extending transversely to the longitudinal axis 9 of the boot. The combs 12 of these ribs are formed with an acute angled cross section, so that said ribs can be easily deformed. These ribs contact the waist leathers 2 and 3 to seal the gap 5. As shown in FIG. 4, the combs 12 of the ribs 10, 11 extend in an arcuate manner relative to the underside 7, with the ends 13 at which the height a of the sealing member 6 lies on either side of the longitudinal axis of the shell. It is decreasing towards .
