Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever protection band.

[0002]

2. Description of the Related Art In a shoe such as a ski shoe, which is composed of an integrally molded shell and is fastened with a tightening lever after the shoe is put on, the tip of the shell is attached to the outer region in front of the shell by an adhesive or a rivet. Lever protection bands that can be stopped are now well known.

Such a band slightly protrudes from the side surface of the shell. An important requirement that this band must possess is to protect the tightening lever on the shell against accidental blowouts and impacts.

[0004]

However, such bands have some problems. First of all
In addition, the known method used for fixing the lever protection band to the shell is that the protection of the lever as its job cannot be completely achieved.

Thus, the use of fastening means such as pins, screws, snaps, or adhesives allows the lever protection band to be partially or wholly peeled off if it is subjected to a sudden impact. The result is that the protection function is lost.

Secondly, in the manufacture of the shell, the lever protection band cannot always be fixed in a good condition, but an extra step is required to carry out the fixing.

Therefore, an object of the present invention is to eliminate the above-mentioned conventional problems by providing a protective band capable of optimally protecting the lever against a sudden impact.

[0008] Among them, a particularly important object is to provide a protective band which is free from partial or total peeling or failure during its use, even in the event of a sudden impact on an unsharp object. That is.

Another object is to provide a protective band that can be placed in an optimal position on the shell. Another important objective is to provide a protective band that is structurally simple, easy to industrialize, reliable and safe to use, and low in manufacturing cost.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in the drawings. The present invention is not limited to this.

Further features and advantages of the invention will become apparent from the particular detailed description illustrated by the non-limiting examples, accompanied by figures, as follows. That is, FIG.
Is a perspective view of the lever protection band, FIG. 2 is a tip view of the lever protection band, FIG. 3 is a bottom view of the lever protection band, FIG. 4 is an inside view of the lever protection band, and FIG. 5 is lever protection installed inside the tip of the shell. FIG. 5 is a sectional view of the band taken along the plane VV of FIG. 4.

In these figures, the lever guard band is indicated generally by the reference numeral 1 and the tip 3 of the shell 4 is shown.
Can be joined laterally to the front area 2 of
The purpose is to protect a lever 5 arranged to traverse the shell 4.

The lever protection band 1 is cage-shaped and comprises an arcuate central body 6 having a second end 8 and a first end 7 having a larger cross section than the second end 8. Has been done.

The recess 10 is formed on the side surface 9 of the arcuate central body 6 facing outward of the shell 4. The inner surface 11 is provided on the opposite surface of the recessed portion 10, and the inner surface 11 is provided with a pair of centering holes 12a, 12b for molding for molding the shell 4 at a predetermined position.
Are formed substantially symmetrically or mirror-symmetrically with respect to the longitudinal center axis.

A plurality of transverse lower portions 13 are provided on the inner surface 11 so that they can be fixed to the shell 4.

The connecting surface 15 is the upper edge 14 of the arcuate central body 6.
And the connection surface 15 is formed with a plurality of openings 16 of various shapes.

The connecting surface 15 is provided at the center with a handle wing 17 for fixing to the shell 4 and directed towards the heel region 180.

Two guides 18a and 18b for fixing to the bottom of the shell 4 are provided on the side opposite to the connecting surface 15 on the side surface 9.
It projects almost at a right angle to. The guides 18a, 1
8b are arranged parallel to each other and connected laterally by a bridge 19.

The lever protection band 1 is located in the mold of a shell 4 obtained by molding it in a fixed position.

Preferably, the pair of centering holes 12
a, 12b, a connecting surface 15 for connecting to the upper edge portion 14 of the arcuate central body 6, and guides 18a, 18b for gripping
With the bridge 19, optimum centering with respect to the shell 4 can be achieved.

Therefore, complete encapsulation of the lever protection band 1 in the shell 4 is achieved and an integrated unit is obtained.

The lever protection band 1 includes the shell 4
Located in the region of the tip 3 of the shell, and only its first end 7 projects from the side of the shell 4. The first
The end 7 is arranged on the outer side of the foot and in front of the lever 5 in order to protect the lever 5.

Instead, the second end 8 is flush with the side of the shell 4 and the upper edge 1 of the arcuate central body 6 is
4 and the lower edge portion 20 in the same manner.
It is the same surface as the side surface of.

The use of the invention is as follows. Once inserted into a suitable mold, the lever protection band 1 is optimally centered by the effect of the presence of the pair of centering holes 12a, 12b and the gripping guides 18a, 18b and bridge 19.

Further, once molded in a fixed position, the existence of the connecting surface 15, that is, the opening 16 and the handle wing 1
Due to the effect of 7, optimum retention in the shell 4 is achieved.

Preferably, while skiing downhill, if the shoe hits a natural or artificial obstacle, such as a stone or slalom pole, the lever protection band 1 will be the first. The lever 5 is protected by the effect of the lever protection band 1 by colliding with an obstacle and receiving an impact.

Therefore, the lever protection band 1 protects the lever 5 from the above-mentioned problems and purposes, that is, the lever 5 against a sudden impact such as opening or breaking of the lever 5, so that the tightening lever 5 is optimized. Achieve good protection,
I understand that.

The lever protection band 1 according to the present invention is naturally capable of accepting numerous partial changes and changes, provided that they are all within the scope of the same inventive concept. Of course, the materials and dimensions of the individual elements that make up the structure may be most appropriate according to particular requirements.

[0040]

According to the present invention, the lever can be optimally protected against a sudden impact. Further, during use, even if a sudden impact is mainly applied to a non-sharp object, partial or total peeling or failure does not occur. Furthermore, it can be placed in an optimal position on the shell. Further, it is structurally simple, easy to industrialize, reliable and safe in use, and further, manufacturing cost can be reduced.
