Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heating device used when fitting an inner boot interposed between the shell of a ski boot and a foot, and for accommodating the inner boot. an accommodating part, a hot air device for producing hot air, and an air blower connected to an outlet of the hot air device, guided into the accommodating part, and having an opening inside the accommodating part formed in a thickness that can be inserted into an inner boot. By means of an inner boot heating device consisting of a tube,
The fitting process for inner boots can be carried out in a short time.

``Prior Art and Problems to be Solved by the Invention'' The shell of ski boots is formed hard, and the shape of the foot differs from person to person, so there is a gap between the shell and the foot. An inner boot is provided to hold it comfortably and without loosening.

As this type of inner boots, those using gum pads are provided. Inner boots using this gum pad were designed to deform the gum pad to fit the shape of the foot. The gum that makes up the gum pad becomes flexible when heated, so the fitting process for inner boots was performed after warming them by placing them in a kotatsu or thermostatic box.

However, with inner boots made of this type of gum pad, there is a problem that the shape of the gum pad changes during use.

Therefore, in order to deal with this problem, the present inventors proposed an inner boot using a thermoplastic resin as a fitting material. These inner boots are made of fluidized thermoplastic resin and fit to the shape of the foot.

However, when trying to fit the proposed inner boots using a thermostatic box as in the past, it takes time to complete the fitting process because it is difficult to raise the temperature inside the inner boots, and it is difficult to heat the fitting material evenly. However, there was a problem in that it was not possible to perform a satisfactory fitting process.

"Means for Solving the Problems" In the present invention, there is provided a storage part that stores inner boots, a hot air device that produces hot air, and a hot air device that is connected to an outlet of the hot air device and that is guided into the surface storage portion and is housed therein. The above-mentioned problem has been solved by an inner boot heating device comprising an air pipe whose opening on the inner side is formed in a thickness that allows it to be inserted into the inner boot.

The housing part constituting the inner boot heating device of the present invention is
The part that forms the enclosed space for accommodating the inner boot, and the member that surrounds the inner boot, can be made of various materials such as a sheet-like material such as cloth or a plate such as a heat insulating board.

The hot air device preferably blows out hot air at about 100 to 200°C, particularly about 150°C. In addition, the air volume of the hot air device is 1 m per pair of inner boots.
It is desirable that the speed is 3/min or more.

A single hole or a large number of holes may be formed in the opening of the air pipe on the accommodating side.

Further, the opening on the housing section side of the blast pipe may be formed in an appropriate shape such as an L-shape.

The hot air blown from the hot air device may be circulated back to the hot air device via the storage section, or may be released into the atmosphere from the storage section.

"Operation" To carry out a fitting process using this inner boot heating device, first, the inner boot is housed in the housing section.

Then insert the air pipe into the inner boot. When the hot air device is driven in this state, hot air is blown into the inner boot and the inside of the inner boot is heated. In addition, the hot air blown into the inner boot flows out from the inner boot and raises the temperature inside the storage section, so that the inner boot is also heated from the outside. As a result, the inner boot is heated from both sides with the inside being slightly warmer than the outside.

"Example" Hereinafter, the inner boot heating device of the present invention will be described in detail with reference to the drawings.

(Embodiment 1) FIG. 1 shows a first embodiment of the inner boot heating device of the present invention, and reference numeral 1 in the figure indicates a housing portion.

This accommodating part 1 is a part that accommodates an inner boot 2.2. This housing part 1 is in the shape of a rectangular parallelepiped, with five sides surrounded by heat-insulating wall plates 3, and the remaining one side consisting of a door 4.4 made of a heat-insulating plate. Moreover, an exhaust port 5 is formed in one of the wall plates 3 . . . forming the accommodation portion I.

Reference numeral 6 in FIG. 1 is a hot air device. This hot air device 6 has a blowing temperature of 150°C and a blowing air volume of 2 m3/mi.
It is of n. A blast pipe 7 is connected to this hot air device 6.

One end of the blower pipe 7 is connected to the outlet of the hot air device 6, and the other end is led into the housing part l. This blower pipe 7 is made of a flexible tube formed into two forks. The two divided sides of the air pipe 7 are guided from the wall plate 3 into the housing part 1 without touching the upper surface of the housing part l.

Opening part 7a7a of this air pipe 7 on the side led to the housing part l
As shown in FIG. 2, the diameter is such that it can be inserted into the inner boot 2.

Using this inner boot heating device, an inner boot containing a fitting material made of ethylene-vinyl acetate-methyl methacrylate resin (manufactured by Sumitomo Chemical: Acrift CK5006) was subjected to fitting treatment.

First, open the door 4.4 of the housing part l of the heating device, and
Insert the inner boot 2.2 into the inner boot 2.2, and then insert the opening 7a of the air pipe 7 into the inner boot 2,2.

7a was inserted. Next, the door 4.4 of the housing section 1 was closed, and in this state, the hot air device 6 was driven to blow hot air into the inner boot 2.2. The temperature of the hot air blown is approximately 1
The temperature was 50°C. The housing part l of the heating device allows the hot air blown into the inner boots 2.2 to
By flowing out from the inside, the temperature was raised to about 70-80°C.

As a result, the inner boot 2.2 is heated from the inside and outside,
The fitting material inserted into the inner boot 2.2 became flowable in about 5 to 15 minutes.

For comparison, when the same inner boot 2 was housed in a thermostatic box maintained at a temperature of 80° C., it took about 1 hour for the fitting material to become flowable.

As a result, according to the inner boot heating device of the present invention,
It was confirmed that the fitting process could be completed in a short time.

(Embodiment 2) FIG. 3 shows a blow pipe 7 of a second embodiment of the inner boot heating device of the present invention.

The opening 7a of the blower pipe 7 is bent into an L-shape, and the tip thereof is closed. A large number of small lowers b... are bored around it.

In this inner boot heating device, since the opening 7a is formed in an L-shape, the air pipe 7 can be inserted deep into the inner boot 2, and a large number of small lower b...
- Since hot air is blown out from the inner boot 2, the inside of the inner boot 2 can be heated more uniformly.

Note that the inner boot heating device of the present invention can be suitably used to heat an inner boot alone, but is not limited thereto, and can also be used to heat treat an inner boot inserted into a ski boot.

"Effects of the Invention" As explained above, the inner boot heating device of the present invention includes a storage part that stores an inner boot, a hot air device that produces hot air, and a hot air device that is connected to the outlet of the hot air device and that The inner boot can be uniformly heated from the inside and outside because it is guided by the air pipe and has an opening inside the accommodating part formed in a thickness that can be inserted into the inner boot.

Therefore, according to this inner boot heating device, the fitting process can be performed in a short time and satisfactorily.
