Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tire warmer used in a car race or the like.

[Conventional technology]

In a car race, a tire warmer that heats and keeps a tire at a predetermined temperature in advance is used at the time of starting a tire or replacing a tire during a race. The reason why the tire is preheated is that the tire is softened to improve the grip performance of the tire on the road surface to speed up the vehicle and to improve the cornering.

A conventional tire warmer is one in which a heating element is attached to a belt-shaped sheet, which is wound around the outer peripheral surface of the tire and the heating element is energized to heat and keep the tire warm.

[Problems to be solved by the device]

When heating a tire with a conventional tire warmer,
Even if the tire is heated, the heat is rapidly dissipated through the wheel inside the tire, so that there is a drawback that it is easily cooled. For this reason, not only the thermal efficiency at the time of heating and heat retention is poor, but also the tire may be cooled during the mounting of the tire on the vehicle.

Also, in car racing, it is necessary to heat and keep many tires warm at the same time, but in the conventional tire warmer, it is necessary to wind each tire, so it takes time and the temperature of each tire is uniform. There was a problem that it was difficult to heat and keep warm at various temperatures.

Therefore, it is an object of the present invention to provide a tire warmer in which a heated tire is hard to cool, and moreover, a large number of tires can be uniformly heated and kept warm at one time.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention comprises a combination of a main body provided with a tire support and a lid, a heater is attached to the main body, and a tire storage chamber formed by the main body and the lid is provided. The heater is used for heating.

In addition, a peripheral wall that rises around the main body may be provided, and the lid may include a bellows-type cover and an upper plate that closes the upper end of the cover, and the hem portion of the cover may be inserted inside the peripheral wall. it can.

Further, the above-mentioned main body may be formed in a box shape whose upper surface is opened, and a lid may be attached to the open end edge so as to be openable and closable.

[Action]

In the tire warmer, a required number of tires are placed on the tire support base of the main body, a lid is put on the tire supporter, and then a heater is operated to generate hot air. The heater is controlled so as to heat the entire tire and wheel, and shift to heat retention when a predetermined temperature is reached.

〔Example〕

As shown in FIGS. 1 and 2, the tire warmer of the embodiment comprises a combination of a main body 1 and a lid 2. The main body 1 is provided with a peripheral wall 4 standing around the circular substrate 3, and the peripheral wall 4
A hot air blower 5 as a heater is attached to a part of the above. The blower pipe 6 connected to the blower opening of the warm air blower 5 extends to the central portion of the substrate 3, and its tip is bent upward and is open. A disk-shaped diffusion plate 9 is provided above the tip of the blower pipe 6. Furthermore, blower pipe 6
An intake pipe 6'is provided in the vicinity of, so that the internal air is sucked into the warm air blower 5 and the circulation of warm air is improved.

On the upper surface of the substrate 3, by attaching several plate pieces radially around the open end of the blower pipe 6,
A tire support base 7 is provided. A caster 8 is attached to the lower surface of the substrate 3 so that it can be moved freely in any direction.

The lid 2 is a bellows type cylindrical cover 10 with the upper end closed and the lower end opened.
And an upper surface plate 11 fixed to the inner surface of the closed portion. The cover 10 is made of a heat insulating sheet, and a ring-shaped wire 12 is attached to reinforce the bellows portion (see FIG. 3). Further, three support plates 13 are radially attached to the lower surface of the upper surface plate 11.

The hem part of the cover 10 is inserted along the inner side of the peripheral wall 4 of the main body 1, and when this is folded, as shown in FIG.
10 is folded inside the peripheral wall 4. By making the mounting positions of the plate pieces of the tire support base 7 on the substrate 3 and the support plates 13 of the upper surface plate 11 different, the plate of the tire support base 7 when the cover 10 is folded as described above. The piece and the support plate 13 do not interfere with each other. In the illustrated case, the support plate 13 is taller and is formed at substantially the height of the peripheral wall 4, so that the height of the upper end surface of the lid 2 in the folded state is as shown in FIG. Match the height of the surrounding wall 4.

In order to prevent the lid 2 from coming out in the folded state, the upper end of the belt 14 is fixed to the upper end surface of the lid 2, and the lower end of the belt 14 and the lower surface of the substrate 3 are fixed by surface fasteners 15a and 15b. ing.

It should be noted that recesses 16 and 16 'for avoiding the blower pipe 6 and the intake pipe 6'are provided at the lower end of the cover 10 (see FIG. 1).

The tire warmer of the embodiment has the above configuration,
With the lid 2 removed, a required number of tires 17 are stacked on the tire support 7. The tire 17 is mounted at a position where the bub portion of the wheel 18 thereof is located above the diffusion plate 9 of the blower pipe 6.

Next, the lid 2 is covered, and the support plate 13 is placed on the upper surface of the uppermost tire 17.
And support the lid 2 and put the hem of the cover 10 inside the peripheral wall 4.

After that, when the warm air blower 5 is operated, warm air blows out from the open end of the blower pipe 6 and is diffused by the diffusion plate 9 so that the gap between the outer peripheral surface of the tire 17 and the inner peripheral surface of the cover 10 and the wheel. It circulates in a path that passes through the gap 18 and reaches the upper surface of the cover 10 and returns to the lower end through the space between the support plates 13 at the upper end of the cover 10. As a result, the temperature inside the tire storage chamber rises, and the tire 17 and the wheel 18 are heated at the same time.

Although the temperature of the tire 17 varies depending on the type of the tire and the like, by controlling the hot air blower 5, when the temperature of the tire 17 usually reaches 60 to 70 ° C, the heating is stopped and the temperature is maintained.

In the embodiment, the heater using the warm air blower 5 is shown, but a heater such as a gas stove or a petroleum heater may be used instead.

Next, FIG. 5 shows another embodiment, in this case, the main body 1
Is composed of a box-shaped container, and a lid 2 is provided on one side edge of its open end.
It is attached so that it can be opened and closed freely.

A warm air device 5 which is separate from the main body 1 is attached to one side portion of the main body 1 and blows warm air inside. In addition, inside the main body 1,
A tire support base 7 is provided for supporting tires 17 by arranging tires 17 with the axes of the wheels oriented horizontally. Further, casters 8 are attached to the lower surface of the main body 1.

Also in the case of this embodiment, the lid 2 is covered with the required number of tires 17 leaning on the tire support 7, the warm air blower 5 is operated to heat the tires 17, and then the temperature is maintained.

〔effect〕

As described above, according to the present invention, not only the tire but also the wheel is integrally heated in the tire storage chamber constituted by the main body and the lid, so that the tire is hard to cool.

Further, since it is possible to heat and heat a large number of tires at a time, it is not only efficient, but also the temperature of each tire can be kept constant, and it is convenient because a plurality of tires can be transported while being stored.
