Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a device for preventing the free end of the ratchet band from slipping off from the band metal fittings for ski boots.

Figures 1 and 2 are used to tighten the opening/closing part of conventional ski boots.
As shown in the figure, a band metal fitting 4 is fixed to one side of the opening/closing part, and one end of a ratchet band 5 is fixed to the other side of the opening/closing part, and the band 5 has an inclined surface 5b and a step 5.
A ratchet band is used in which the ratchet teeth of the ratchet band 5 are formed on the ratchet teeth of c and are configured so that the ratchet teeth of the ratchet band 5 engage with the locking portions of the step 8b and the inclined surface 8c of the locking member 8 of the band metal fitting 4. However, if the ski boots are loosened too much when putting them on or adjusting the comfort of the shoes, or if the rear tongue member 3 of the ski boots is rotated significantly backwards, the free end 5a of the band may When wearing ski boots or wearing skis, the freedom of bending the body is restricted, and in cold conditions, when the temperature is low, hands become stiff with or without gloves, making it difficult to perform manual operations. Therefore, both methods have the disadvantage that it is difficult to insert the free end of the band into the band fitting, and the insertion is not easy.

In view of the above-mentioned drawbacks, the purpose of the present invention is to provide a ratchet band for ski boots, which includes a simple retaining member attached to the free end of the band to prevent the free end of the band from accidentally slipping out of the band fitting. The purpose is to propose a locking device.

Hereinafter, the present invention will be explained with reference to the illustrated embodiment. The ratchet band slip-off prevention device of a ski boot is shown in FIGS. A rear tongue-like member 3 provided so as to overlap on both sides of the opening and closing part 2a, a band fitting 4 fixed to one side of the opening and closing part 2a, and a ratchet band 5 having one end fixed to the other side of the opening and closing part 2a. A retaining member 6 is attached to the free end 5a of the holder.

As shown in FIGS. 4 and 5, the band fitting 4 is composed of an elongated frame 7, a locking member 8, a fixing fitting 9 for fixing to the shoe 1, and a holding fitting 10 for the ratchet band 5. Pins 11, 11 on one side from the center
A locking member 8 and a restraining metal fitting 10 are rotatably supported, and a fixing metal fitting 9 is mounted on one side of the frame 7 with pins 12, 12.
It is rotatably supported.

At both longitudinal ends of the lower side of the locking member 8, there is a flat portion 8a, two steps 8b in the middle, and two inclined surfaces 8.
c are respectively formed, and fine irregularities 8d are formed on the upper surface.

The ratchet band 5 has an inclined surface 5b on its surface.
A ratchet tooth is formed at the step 5c, and a fixing part 5d to the shoe is formed at one end.

As shown in FIGS. 7 and 8, the retaining member 6 is made of a metal plate and is bent into an inverted square shape when viewed from one side, with an opening 6a formed on one side, and a lower side 6b protruding long toward the front. , an inclined tongue piece 6d protrudes rearward from the upper side 6c.

When the above-mentioned retaining member 6 is attached to the ratchet band 5, it is attached to the ratchet band 5 as shown in FIG.
After the free end 5a is inserted between the lower side of the locking member 8 of the band fitting 4 and the holding fitting 10, the free end 5a
The retaining member 6 is fitted into an arbitrary position on the side so as to expand the opening 6a from the side, and the tongue piece 6
d along the inclined surface 5b of the ratchet tooth, and the step 5
It is installed by being perforated at c.

The free end 5a of the ratchet band 5 as described above.
is inserted into the band fitting 4, the step 5c of the ratchet teeth of the ratchet band 5 is engaged with the step 8b formed at an arbitrary position on the locking member 8 of the band fitting 4, and the locking member 8 is stopped. In FIG. 6, by pushing down the arrow a position on the upper surface of one side, the engagement between the steps 5c and 8b is released, and the ratchet band 5 can be pulled out in the loosening direction.

Even if the ratchet band 5 is loosened by the above operation, if the retaining member 6 is attached to the ratchet band 5, the front end of the upper side 6c of the retaining member 6 is engaged with the step 8b, and the free end 5a is It is possible to prevent the band from coming off from the metal fitting 4.

Therefore, the band fitting 4 and the ratchet band 5 are attached to the ski boot 1, and the frame 7 of the band fitting 4 is attached.
Lift one side and press the upper surface of one side of the locking member 8 to loosen the ratchet band 5 and release the rear tongue member 3 to insert the foot into the ski boot 1 as shown in FIG.
The length of the ratchet band 5 is such that even if it is pushed open backwards as shown by the dotted chain line, the ratchet band 5 is prevented from slipping out from the band fitting 4 as shown in the upper example, and the opening/closing amount of the opening/closing portion 2a is loosened. It is regulated by

In the above description, the retaining member 6 is made of a metal plate material, but it may be made of other materials, or may be made of a synthetic resin material and fixed to the free end 5a of the ratchet band 5 in advance.

Furthermore, in the above explanation, the opening/closing part 2a is provided on the rear side of the main body 2 of the ski boot 1 so that the rear tongue-like member can rotate rearward. May be implemented.

Since the present invention is constructed as described above, the ratchet band does not easily come off from the band fitting due to the retaining member attached to the ratchet band.
This eliminates the trouble of having to insert the ratchet band into the band metal fittings when it comes off, and has excellent practical effects such as being able to arbitrarily regulate the amount of opening and closing of the opening/closing part depending on the position where the retaining member is attached to the ratchet band. It is possible to provide a ratchet band slipping prevention device for ski boots that achieves the following functions.
