自動車や自動二輪車の速さを競うカーレースにおいては、スタート時或いはレ ース途中におけるタイヤ交換時において、予めタイヤを所定温度に加熱・保温す るタイヤウォーマーが使用される。タイヤを予め加熱するのは、走行開始の初期 においてはタイヤが比較的硬いことにより、路面に対するグリップ性やコーナリ ング性が劣るためである。タイヤを予め加熱しておけば、走行開始時にタイヤが 柔軟化しているため、走行性が向上する利点がある。 In car races where cars and motorcycles compete for speed, the When changing tires during a race, heat and keep the tires at the specified temperature in advance. Tire warmers are used. Preheat the tires at the beginning of driving. Because the tires are relatively hard, they have poor grip on the road surface and cornering. This is because the handling properties are poor. If you heat the tires in advance, they will be warmer when you start driving. Since it is flexible, it has the advantage of improving running performance.
【０００３】 このような目的で使用される従来のタイヤウォーマーは、帯状シートの内部に ヒーターを取付けたものであり、これをタイヤの外周面に巻付け、ヒーターに通 電することによりタイヤを加熱・保温するようになっていた。0003 Conventional tire warmers used for this purpose have a A heater is attached, which is wrapped around the outer circumference of the tire and passed through the heater. The tires were heated and kept warm by electricity.

しかし、上述の従来のタイヤウォーマーによりタイヤを加熱・保温する場合、 タイヤの外周面は幅方向にわん曲しているのに対し、タイヤウォーマーは平坦な 帯状のものであってそれ自体の柔軟性のみでタイヤのわん曲面に沿わせるように している。このため、タイヤに対する密着性が悪く、加熱効率が低い欠点があっ た。 However, when heating and keeping tires warm using the conventional tire warmer described above, The outer circumferential surface of a tire is curved in the width direction, whereas a tire warmer is flat. It is a band-shaped material that can be made to follow the curved surface of the tire using only its own flexibility. are doing. This has the disadvantages of poor adhesion to tires and low heating efficiency. Ta.
【０００５】 そこで、この考案はタイヤに対する密着製の良好なタイヤウォーマーを提供す ることを課題とする。[0005] Therefore, this idea provides a tire warmer that adheres well to the tire. The challenge is to

【課題を解決するための手段】 上記の課題を解決するために、この考案は柔軟な帯状シートにヒータを取付け 、そのシートをタイヤの外周面に着脱自在に装着するようにしたタイヤウォーマ ーにおいて、上記の帯状シートの両側辺に所定の間隔をおいてシート中心方向の 切込みを多数設け、前記切込みをその先端に至るに従い次第に切欠み幅を小さく 形成し、各切欠みの対向辺を引き寄せて縫着した構成としたものである。[Means to solve the problem] In order to solve the above problems, this invention attaches a heater to a flexible strip sheet. , a tire warmer whose sheet is removably attached to the outer circumferential surface of the tire. - In the above-mentioned belt-shaped sheet, place a predetermined interval on both sides of the sheet in the direction of the center of the sheet. A large number of notches are provided, and the notch width gradually decreases as the notches reach the tip. The opposite sides of each notch are drawn together and sewn together.

シートの両側辺に多数設けられた各切込みの対向辺を引き寄せて縫着し、その シートの両端を突き合わせると、シートの中心部はタイヤの最大周長に相当する 長さを有する。その中心部からシートの両側辺に至るに従い周方向の長さが次第 に短くなり、両側辺においてはタイヤの加熱すべき部分の最小周長に等しくなる 。 The opposite sides of each of the many notches on both sides of the sheet are drawn together and sewn together. When the two ends of the sheet are brought together, the center of the sheet corresponds to the maximum circumference of the tire. It has a length. The length in the circumferential direction increases from the center to both sides of the seat. on both sides, equal to the minimum circumference of the part of the tire to be heated. .
【０００８】 このため、タイヤの周方向及び半径方向の形状に沿い易くなり、密着性が向上 する。[0008] This makes it easier to follow the shape of the tire in the circumferential and radial directions, improving adhesion. do.

図１に示すように。実施例のタイヤウォーマーは、所定幅の内シート１と外シ ート２の間にヒータ３を取付け、内外両シート１、２の両側辺を縫着し、一端の 内面と他端の外面に雌雄の係着具４、５を取付けたものであり、ヒータ３に通電 するための電源コード６を備えている。また、内シート１の内面に温度センサー ７を取付け、そのセンサー７の出力により、電源コード６に接続した温度調節器 ９をオン・オフ制御するようになっている。 As shown in Figure 1. The tire warmer of the embodiment has an inner sheet 1 of a predetermined width and an outer sheet 1 of a predetermined width. Attach the heater 3 between the sheets 2, sew both sides of the inner and outer sheets 1 and 2, and Male and female fasteners 4 and 5 are attached to the inner surface and the outer surface of the other end, and the heater 3 is energized. It is equipped with a power cord 6 for In addition, a temperature sensor is installed on the inner surface of inner sheet 1. 7 is installed, and the temperature controller connected to the power cord 6 according to the output of the sensor 7. 9 is turned on and off.
【００１０】 上記のタイヤウォーマーは、図２に示すように、タイヤ８の外周面に沿って被 せられ、両端部を重ねて係着具４、５により固定するようになっており、ヒータ ３に通電することによりタイヤ８を加熱・保温する。0010 As shown in FIG. 2, the tire warmer described above is coated along the outer peripheral surface of the tire 8. The heater is The tire 8 is heated and kept warm by energizing the tire 3.
【００１１】 上記の内シート１と外シート２は、柔軟な耐熱性のシートにより構成され、タ イヤ８の外形面への密着性を良好にするため、次のような構成になっている。[0011] The above-mentioned inner sheet 1 and outer sheet 2 are made of flexible heat-resistant sheets. In order to improve the adhesion to the outer surface of the ear 8, the following configuration is adopted.
【００１２】 即ち、内シート１（外シート２についても同様）は、図３に示すように、長さ をＬ（タイヤ８の最大周長Ｌ1 に両端部の重なり部９、９を加えた寸法）、幅を Ｗ（タイヤ８の加熱すべき半径方向の幅Ｗに等しい。図４参照）とする。この内 シート１を製作する手順は、まず図３に示すように内シート１の両側辺に一定の 間隔をおいて多数の切込み１１を両側辺の対向する位置に設ける。この切込み１ １の幅は側辺において最大であり、内シート１の中心に近づくに従い次第に狭く なっており、切込み１１の対向辺１２、１２は円弧状になっている。この切込み １１の形状は次のようにして決定される。That is, as shown in FIG. 3, the inner sheet 1 (the same applies to the outer sheet 2) has a length L (the maximum circumference L 1 of the tire 8 plus the overlapping parts 9 and 9 at both ends). dimension), and the width is W (equal to the radial width W of the tire 8 to be heated; see FIG. 4). The procedure for manufacturing the inner sheet 1 is as shown in FIG. 3, in which a large number of incisions 11 are first made at opposite positions on both sides of the inner sheet 1 at regular intervals. The width of this cut 11 is maximum at the side edge, and gradually becomes narrower as it approaches the center of the inner sheet 1, and the opposing sides 12, 12 of the cut 11 are arcuate. The shape of this cut 11 is determined as follows.
【００１３】 いま、図４に示すように、タイヤ８の幅方向の中心（最大周長の部分）におけ る半径をＲ1 とし、そのＲ1 の部分から半径方向に所定幅離れた点の半径を順次 Ｒ2 、Ｒ3 、Ｒ4 とし、加熱すべき部分の最小周長となる部分の半径をＲ5 とす る。Now, as shown in FIG. 4, the radius at the widthwise center (maximum circumference portion) of the tire 8 is R 1 , and the radius at a point a predetermined width away from the R 1 portion in the radial direction is Let R 2 , R 3 , and R 4 be in order, and let R 5 be the radius of the portion having the minimum circumference of the portion to be heated.
【００１４】 上記の半径Ｒ1 の部分における周長（最大周長）をＬ1 （＝２πＲ1 ）とし、 順次半径Ｒ2 、Ｒ3 、Ｒ4 、Ｒ5 における周長をＬ2 、Ｌ3 、Ｌ4 、Ｌ5 とする 。The circumference (maximum circumference) at the radius R 1 is L 1 (=2πR 1 ), and the circumference at the radii R 2 , R 3 , R 4 , R 5 is L 2 , L 3 . , L 4 and L 5 .
【００１５】 更に、一側辺上の切込み１１の数をＮとすると、各切込み１１の最大幅は、Ｌ1 −Ｌ5 ／Ｎとなる。そこで、切込み１１の先端の位置を基準として、その両側 に等寸法をとって、全体としてＬ1 −Ｌ5 ／Ｎの幅となる点をプロットし、順次 Ｌ1 −Ｌ4 ／Ｎ、Ｌ1 −Ｌ3 ／Ｎ及びＬ1 −Ｌ2 ／Ｎとなる点をプロットして各 点を結べば、対向辺１２、１２の形状が得られる。Furthermore, if the number of cuts 11 on one side is N, the maximum width of each cut 11 is L 1 -L 5 /N. Therefore, using the position of the tip of the notch 11 as a reference, take equal dimensions on both sides and plot the points that have a width of L 1 -L 5 /N as a whole, and sequentially calculate the width of L 1 -L 4 /N, L 1 By plotting the points where −L 3 /N and L 1 −L 2 /N and connecting the points, the shapes of the opposing sides 12, 12 can be obtained.
【００１６】 なお、生地を裁断する際は、縫い代１３を残す。[0016] Note that when cutting the fabric, leave a seam allowance of 13.
【００１７】 上記の対向辺１２、１２をひ引き寄せて相互に縫着すると、切込み１１の最大 幅の部分が最も大きく引き寄せられ、切込み１１の先に至るに従い次第に引き寄 せ量が小さくなり、先端においては引き寄せ量が零になる。[0017] When the opposing sides 12 and 12 are pulled together and sewn together, the maximum depth of the cut 11 is The width part is pulled the most, and as it reaches the tip of the notch 11, it is gradually pulled The amount of pulling becomes small, and the amount of pulling becomes zero at the tip.
【００１８】 このため、内シート１は長さ方向の両側辺の部分が最小周長Ｌ5 となる（但し 、重なり部９、９を除く）。また内シート１の中心部分の長さは、最大周長Ｌ1 となる。Therefore, the inner sheet 1 has a minimum circumference L 5 on both sides in the length direction (excluding the overlapping portions 9 and 9). Further, the length of the center portion of the inner sheet 1 is the maximum circumferential length L1 .
【００１９】 この場合、切込み１１の数Ｎが少なく、切込み１１相互間の間隔が長くなると 、シート両側辺の形状がタイヤ８の周方向の円弧に沿い難いので、切込み１１の 数Ｎは、タイヤへの密着性を損わない程度に適宜の数に定められる。[0019] In this case, if the number N of notches 11 is small and the distance between the notches 11 is long, , since the shape of both sides of the seat is difficult to follow the circular arc in the circumferential direction of the tire 8, the cut 11 is The number N is determined to be an appropriate number so as not to impair the adhesion to the tire.
【００２０】 上記のようにして製作された内シート１と外シート２とを、両者の間にヒータ ３を挟んで相互に縫着すると、図１に示すように、半径方向には樋状にわん曲し 、周方向には円弧状の形状をもったタイヤウォーマーが得られ、図２のようにタ イヤ８の外周面に装着すると、その外形面に密着する。[0020] A heater is placed between the inner sheet 1 and outer sheet 2 manufactured as described above. When 3 is sandwiched and sewn together, it curves in the radial direction like a gutter, as shown in Figure 1. , a tire warmer with an arcuate shape in the circumferential direction is obtained, and the tire warmer has a circular arc shape in the circumferential direction. When attached to the outer circumferential surface of the ear 8, it will come into close contact with the outer surface.
【００２１】[0021]
以上のように、この考案のタイヤウォーマーはタイヤの外形面に対する密着性 が良好であるため、タイヤ全体を効率よく加熱することができる効果がある。 As mentioned above, the tire warmer of this invention has excellent adhesion to the outer surface of the tire. Since the temperature is good, the entire tire can be heated efficiently.
