Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a ski boot including an outer shell and an inner boot made of synthetic resin, and the outer shell is partially adapted to the shape of the foot. The present invention relates to a ski boot straightening device.

(Prior Art) Most of the present ski shoes are composed of an outer shell and an inner boot. In this case, the outer shell is formed by a pair of molding processes from a hard synthetic resin such as vinyl or plastic, while the inner boot is made of a foamed foam material and has a surface finished with leather or a fluid object (gel). Material) is built in, and designed in consideration of fit. By the way, the shape of the human foot is infinite, and the unevenness of the foot is absorbed to some extent by this flexible inner boot,
It is configured to fit the shape of a hard outer shell, but depending on the person, a part of the foot such as the ankle may hit the ski shoe, that is, the outer shell, and a sufficient fit may not be obtained, and it sometimes becomes painful. was there. In such a case, a soft material was attached to the inner boots around the contact part to weaken the hit, but since the shape of the outer shell does not fit the foot, it still seems to be worn for a long time. My legs hurt. Further, since the outer shell is made of synthetic resin, there is also a method in which hot air is blown to the portion hitting from the outside to soften the portion and press it from the inside so that the portion hit by the foot is projected outward.

(Problems to be solved by the invention) However, this method heats and deforms the outer shell by applying hot air at about 150 ° C, so the surface of the outer shell is melted by heat and the appearance deteriorates. Even if it protruded to the outside, it was not an effective means because it returned to the original state again due to its restoring force during natural cooling.

Therefore, the present invention has been made based on the above-mentioned problems, and an object thereof is to provide a straightening device for a ski shoe, which can surely deform a portion of the outer shell that comes into contact with a foot without damaging the appearance. Is.

[Means for Solving the Problems] (Means for Solving the Problems) The present invention is an arm having one end fixed to a base and into which an outer shell of a ski boot can be inserted, and an arm provided at the other end of the arm from the inside of the outer shell. A heating unit for applying heat and a pressing unit which is provided on the base so as to face the heating unit and presses the outer shell around the heating unit from the outside are provided.

(Operation) The portion of the outer shell which the foot touches is warmed from the inside by the heating unit, and the periphery of the outer shell is pressed to thermally deform the portion which hits the heating unit to correct the portion where the dent foot hits.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings. 1
Is a base, and the support column 2 is hung vertically upward. Reference numeral 3 denotes a first arm which is horizontally fixed to the column 2 and into which an outer shell 4 of a ski boot can be inserted, and a heating portion 5 having an approximately spherical upper surface protruding upward is provided at a tip thereof. A heater 6 is built in the heating unit 5, and is energized by turning on a power switch 8 of a control box 7 provided on the base 1, and its temperature is adjusted by turning a temperature adjusting knob 9.

Reference numeral 10 denotes a second arm which is horizontally fixed to the support column 2 in parallel with the first arm 3, and a female screw portion 11 is provided at a tip end thereof in a vertical direction so as to face the heating portion 5. Reference numeral 12 denotes a male screw rod that is screwed to the female screw portion 11 and can move up and down. A handle 13 is provided at the upper end of the male screw rod 12 and a substantially spherical universal joint 14 is provided at the lower end thereof. Reference numeral 15 is a pressing portion that presses the outer shell 4 from the outside, and a recess 16 into which the universal joint 14 is fitted is continuously provided on the upper portion thereof. The pressing portion 15 is made of a flexible material and has a center hole 17 at a position facing the heating portion 5, and is formed in an annular shape.

The operation of the present invention constructed as above will be described in detail below.
If you feel uncomfortable or have a pain when a part of your foot hits the ski boot, wear the outer shell 4 to the first arm 3
The heating part 5 is brought into contact with the inside of the outer shell 4 where a part of the foot hits. Then, as shown in FIG. 2, the handle 13 is operated to lower the male screw rod 12 to lower the pressing portion 15.
The outer shell 4 is pressed by. As a result, the outer shell 4 is sandwiched between the heating portion 5 and the pressing portion 15, the contact portion is pushed upward by the heating portion 5, and conversely, the periphery of the contact portion is pushed downward by the annular pressing portion 15. In this state, the power switch 8 is turned on to energize the heater 6 to warm the heating section 5. At this time, the temperature of the heating portion 5 is preferably about 150 to 200 ° C. when the outer shell 4 is made of vinyl, and about 100 to 150 ° C. when the outer shell 4 is made of plastic, and is appropriately set according to the material. When the heating part 5 is warmed in this way, the part of the outer shell 4 on which the foot hits is warmed from the inside and becomes soft, and the heating part 5 and the pressing part 15 sandwich and press it, so that the hitting part is It is pushed outward due to thermal deformation and dents. It is sufficient that this dent has a size of 1 to 2 mm. Then, after denting, the heater 6 is de-energized, and the outer shell 4 is naturally cooled while being sandwiched between the heating part 5 and the pressing part 15, and then the pressing part 15 is raised when sufficiently cooled. And remove the outer shell 4.

In this way, the portion of the hard outer shell 4 which is touched by the foot is locally pressed by the heating portion 5 to be thermally deformed, so that the ski boot can be straightened without damaging the surface. Further, even after the heat is applied, since the sandwiched state is maintained during the natural cooling, it is prevented from returning to the original state, and the correction can be surely and easily performed.
Further, since the pressing portion 15 freely swings to the left, right, front and back, etc. by the universal joint 14, it can be pressed reliably even if the outer shell 4 has a non-horizontal outer shape.

Although one embodiment of the present invention has been described in detail above, it can be appropriately modified within the scope of the present invention. For example, although the heating unit 5 has a fixed type in which the heater 6 is incorporated, the heating unit may be previously set to a high temperature, but the heating unit may be detachably provided to the first arm 3. Further, although the pressing unit 15 is moved up and down, the heating unit 5 may be moved up and down.

[Effects of the Invention] As described in detail above, according to the present invention, by applying the heating portion to the inner side of the outer shell and pressing the outer shell from the outer side, the outer shell is surely deformed without damaging the appearance of the outer shell. It is possible to provide a straightening device for a ski shoe that can avoid hitting the foot.
