Description

本発明は、自動二輪車や鞍乗型四輪車両(バギー車両、ATV等)のような車両において、エンジンや排気装置等の熱源に対して遮熱を行うための断熱シートおよびそれを用いた車両用カバー部材に関するものである。   The present invention relates to a heat insulating sheet for shielding heat from a heat source such as an engine or an exhaust device in a vehicle such as a motorcycle or a saddle-ride type four-wheeled vehicle (buggy vehicle, ATV, etc.), and a vehicle using the same. The present invention relates to a cover member for use.

自動二輪車等の小型車両では樹脂製カバー部材が多用されており、エンジンや排気装置の近傍に配置される樹脂製カバー部材には耐熱性向上のため熱源側に臨む面に断熱シートが貼着される場合が多い。   In small vehicles such as motorcycles, resin cover members are frequently used, and a heat insulating sheet is attached to the surface facing the heat source for improving the heat resistance of the resin cover members arranged in the vicinity of the engine and the exhaust device. There are many cases.

自動二輪車における樹脂製カバー部材の断熱シート貼着例として特許文献1に記載されているものがある。ここでは、エンジンの上部に設けられるカバー部材の内側に断熱シートが貼着されている。   There exists what is described in patent document 1 as an example of sticking the heat insulation sheet | seat of the resin-made cover members in a motorcycle. Here, the heat insulation sheet is stuck inside the cover member provided in the upper part of an engine.

特開平11−192988号公報
Generally, a heat insulating sheet is obtained by laminating and bonding an inner sheet made of a heat-resistant material such as glass fiber or foaming resin (silicon or the like) to an aluminum sheet, and the inner sheet portion is bonded to the cover member side.
Japanese Patent Laid-Open No. 11-192988

しかしながら、耐熱材質からなるインナーシートはそれ自体の強度が弱くて脆いため、例えば自動二輪車や鞍乗型四輪車両のフェンダーの内側に断熱シートを貼着した場合、高速回転する車輪から飛散する泥水や小石等との衝突および高圧洗車時における水圧等により断熱シートがフェンダーから剥離しやすいという難点があった。特に厚手の断熱シートは端面に水圧が加わると剥離しやすい。反面、薄い断熱シートは剥離しにくいが断熱性能が低い。   However, since the inner sheet made of a heat-resistant material is weak and brittle, for example, when a heat insulating sheet is attached to the inside of a fender of a motorcycle or a saddle-type four-wheel vehicle, muddy water splashes from a wheel that rotates at high speed. There is a problem that the heat insulating sheet is easily peeled off from the fender due to a collision with pebbles or the like and water pressure during high-pressure car washing. In particular, a thick heat insulating sheet is easily peeled off when water pressure is applied to the end face. On the other hand, a thin heat insulating sheet is difficult to peel off, but its heat insulating performance is low.

本発明は、上記問題点を解決するためになされたものであり、断熱性能が高くて被断熱部材からの剥離や貼付不良が起こりにくい断熱シートおよびそれを用いた車両用カバー部材を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a heat insulating sheet that has high heat insulating performance and is unlikely to cause peeling or sticking failure from a member to be heat-insulated, and a vehicle cover member using the heat insulating sheet. With the goal.

上記目的を達成するため、本発明に係る断熱シートは、気質を含む耐熱材質からなるインナーシートの一面にアルミ系合金製の薄膜からなるアウターシートを重ね合わせ、アウターシートの外形輪郭をインナーシートの外形輪郭から所定幅を有してはみ出させてインナーシートの外周全周に亘って連続する延出代を形成し、この延出代とインナーシートの他面とに粘着手段を設けてインナーシートとアウターシートを被断熱部材に貼着可能にしたことを特徴とする。   In order to achieve the above object, the heat insulating sheet according to the present invention has an outer sheet made of an aluminum alloy thin film superimposed on one surface of an inner sheet made of a heat-resistant material including a temperament, and the outer contour of the outer sheet is formed on the inner sheet. An extension allowance extending over the entire outer periphery of the inner sheet is formed by protruding from the outer contour with a predetermined width, and an adhesive means is provided between the extension allowance and the other surface of the inner sheet, The outer sheet can be attached to the heat insulating member.

また、本発明に係る断熱シートは、アウターシートの、インナーシートが重ね合わせられる部分と延出代との境界部に、インナーシートの外形縁を外気に臨ませる欠除部を設けた。   Moreover, the heat insulation sheet which concerns on this invention provided the lack part which makes the external edge of an inner sheet | seat face outside air in the boundary part of the part and the extension allowance of the outer sheet | seat of an outer sheet | seat.

さらに、本発明に係る断熱シートは、前記欠除部を、環状縁を有する開口孔を分散させることにより形成し、この開口孔の位置を、インナーシートの外形縁のうち曲率の小さな部分や直線部分に設けた。   Further, in the heat insulating sheet according to the present invention, the notched portion is formed by dispersing an opening hole having an annular edge, and the position of the opening hole is a portion having a small curvature or a straight line in the outer edge of the inner sheet. Provided in the part.

さらに、本発明に係る車両用カバー部材は、気質を含む耐熱材質からなるインナーシートの一面にアルミ系合金製の薄膜からなるアウターシートを重ね合わせ、アウターシートの外形輪郭をインナーシートの外形輪郭から所定幅を有してはみ出させてインナーシートの外周全周に亘って連続する延出代を形成し、この延出代とインナーシートの他面とに粘着手段を設けてなる断熱シートを、車体内方の熱源に臨みかつ外部への開口部が近接する面に貼着したことを特徴とする。   Further, in the vehicle cover member according to the present invention, an outer sheet made of a thin film made of an aluminum alloy is superposed on one surface of an inner sheet made of a heat-resistant material including a temperament, and the outer contour of the outer sheet is changed from the outer contour of the inner sheet. A heat insulating sheet is formed that has a predetermined width and protrudes over the entire outer periphery of the inner sheet to form an extending margin, and is provided with adhesive means on the extending margin and the other surface of the inner sheet. It is characterized by being attached to a surface facing an internal heat source and having an external opening.

そして、本発明に係る車両用カバー部材は、アウターシートの、インナーシートが重ね合わせられる部分と延出代との境界部に、インナーシートの外形縁を外気に臨ませる欠除部を設けた。   In the vehicle cover member according to the present invention, a notch portion that allows the outer edge of the inner seat to face the outside air is provided at the boundary between the portion of the outer seat where the inner seat is overlapped and the extension allowance.

また、本発明に係る車両用カバー部材は、前記欠除部を、環状縁を有する開口孔を分散させることにより形成し、この開口孔の位置を、インナーシートの外形縁のうち曲率の小さな部分や直線部分に設けた。   Further, in the vehicle cover member according to the present invention, the notched portion is formed by dispersing an opening hole having an annular edge, and the position of the opening hole is a portion of the outer edge of the inner seat having a small curvature. And in the straight part.

さらに、本発明に係る車両用カバー部材は、前記車両用カバー部材を後輪を覆うリヤフェンダーとした。   Furthermore, in the vehicle cover member according to the present invention, the vehicle cover member is a rear fender that covers a rear wheel.

そして、本発明に係る車両用カバー部材は、前記断熱シートおよび別な断熱部材を互いに隣接させて車両用カバー部材に貼着し、別な断熱部材の外縁部の上に断熱シートの延出代を重ねて貼着した。   In the vehicle cover member according to the present invention, the heat insulating sheet and another heat insulating member are adjacent to each other and adhered to the vehicle cover member, and an extension margin of the heat insulating sheet is provided on an outer edge portion of the other heat insulating member. We stuck and stuck.

本発明に係る断熱シートによれば、アウターシート外周の延出代がインナーシートの外形輪郭からはみ出して被断熱部材に貼着されるため、インナーシートの端面が外部に露呈して水圧等を受けることがなく、断熱シートが被断熱部材から剥離することを防止できる。また、インナーシートを構成する耐熱材質の厚みを増すことができるので断熱性能を向上させることができる。   According to the heat insulating sheet according to the present invention, since the extension margin of the outer periphery of the outer sheet protrudes from the outer contour of the inner sheet and is attached to the heat insulating member, the end surface of the inner sheet is exposed to the outside and receives water pressure or the like. It can prevent that a heat insulation sheet peels from a to-be-insulated member. Moreover, since the thickness of the heat resistant material which comprises an inner sheet | seat can be increased, heat insulation performance can be improved.

さらに、アウターシートに設けた欠除部からインナーシートの外形縁が外気に臨むので、断熱シートを被断熱部材に貼着する際にインナーシートに含まれる空気が欠除部から脱気されやすく、貼着不良を防止できるとともに、断熱シートの内部に浸入した水分を欠除部から排出させることができ、この点でも断熱シートの剥離を防止することができる。   Furthermore, since the outer edge of the inner sheet faces the outside air from the notched part provided in the outer sheet, the air contained in the inner sheet is easily degassed from the missing part when the heat insulating sheet is attached to the member to be insulated, The sticking failure can be prevented, and moisture that has entered the inside of the heat insulating sheet can be discharged from the lacking portion. Also in this respect, the heat insulating sheet can be prevented from peeling off.

欠除部はアウターシートの延出代とインナーシートとの境界部に設けられるため、インナーシートの変形を許容するものであり、断熱シートを曲面に容易に貼着させることができて剥離もしにくい。   Since the notched portion is provided at the boundary between the outer sheet extension allowance and the inner sheet, the inner sheet can be deformed, and the heat insulating sheet can be easily attached to the curved surface and is not easily peeled off. .

また、本発明に係る断熱シートを用いた車両用カバー部材によれば、カバー部材の断熱性能を向上させるとともに、断熱シートがカバー部材から剥離したり貼付不良になることを防止することができる。特に使用条件が最も過酷な場所の一つであるリヤフェンダーに適用することにより、リヤフェンダーに信頼性の高い断熱性を付与することができる。   Moreover, according to the vehicle cover member using the heat insulating sheet according to the present invention, it is possible to improve the heat insulating performance of the cover member and to prevent the heat insulating sheet from being peeled off from the cover member or being stuck poorly. By applying it to a rear fender, which is one of the places where the use conditions are particularly severe, it is possible to impart a highly reliable heat insulation to the rear fender.

この鞍乗型四輪車両1のリヤフェンダー29には本発明に係る断熱シートが貼着されており、リヤフェンダー29自体が本発明に係る車両用カバー部材に該当している。図1および図2に示すように、右側のリヤフェンダー29のすぐ内方に、熱源となる排気装置47のエキゾーストパイプ48が配設されているため、この熱源に臨むリヤフェンダー29を熱害から保護するべく、リヤフェンダー29の前部の内面に断熱シート61,62,63が貼着されている。   A heat insulating sheet according to the present invention is attached to the rear fender 29 of the saddle-ride type four-wheel vehicle 1, and the rear fender 29 itself corresponds to the vehicle cover member according to the present invention. As shown in FIGS. 1 and 2, an exhaust pipe 48 of the exhaust device 47 serving as a heat source is disposed immediately inside the right rear fender 29, so that the rear fender 29 facing the heat source is protected from heat damage. Insulation sheets 61, 62, and 63 are attached to the inner surface of the front portion of the rear fender 29 for protection.

図3はリヤフェンダー29の右側の前部付近を下方から見た斜視図である。ここに示すように、リヤフェンダー29の右側前部内面には3枚の断熱シート61,62,63が貼着されている。このうち、前寄りの断熱シート61は従来からある一般的なシート状の断熱部材であり、この断熱シート61の後側に隣接する2枚の断熱シート62,63が本発明に係る断熱シートである。   FIG. 3 is a perspective view of the vicinity of the right front portion of the rear fender 29 as viewed from below. As shown here, three heat insulating sheets 61, 62, 63 are attached to the inner surface of the right front portion of the rear fender 29. Among these, the front heat insulating sheet 61 is a conventional general sheet-shaped heat insulating member, and the two heat insulating sheets 62 and 63 adjacent to the rear side of the heat insulating sheet 61 are the heat insulating sheets according to the present invention. is there.

図4は断熱シート62の平面図であり、図5は図4のV-V線に沿う断熱シート62の縦断面図である。なお、断熱シート62と63は形状が違うだけで同一構造である。   4 is a plan view of the heat insulating sheet 62, and FIG. 5 is a vertical cross-sectional view of the heat insulating sheet 62 along the line V-V in FIG. The heat insulating sheets 62 and 63 have the same structure except for the shapes.

断熱シート62(63)はインナーシート65の一面にアウターシート66を重ね合わせたものである。インナーシート65は発砲樹脂(例えばシリコン)や厚手のガラス繊維および耐熱不織布のような気質を含む耐熱材質からなり、その厚さは例えば3mm〜5mm程度である。一方、アウターシート66はアルミ系合金製の薄膜であり、インナーシート65の一面に貼着されている。アウターシート66は単なるアルミ系薄膜に留まらせず、例えばガラス繊維や金属線等で補強した金属薄膜としてもよい。   The heat insulating sheet 62 (63) is obtained by superposing an outer sheet 66 on one surface of the inner sheet 65. The inner sheet 65 is made of a heat-resistant material including a temperament such as foaming resin (for example, silicon), thick glass fiber, and heat-resistant nonwoven fabric, and the thickness thereof is, for example, about 3 mm to 5 mm. On the other hand, the outer sheet 66 is a thin film made of an aluminum alloy, and is adhered to one surface of the inner sheet 65. The outer sheet 66 is not limited to a simple aluminum-based thin film, and may be a metal thin film reinforced with, for example, glass fiber or metal wire.

アウターシート66の外形輪郭はインナーシート65の外形輪郭から所定幅を有してはみ出しており、インナーシート65の外周全周に亘って連続する延出代67が形成されている。この延出代67の幅は10mm〜20mm程度であるが、必ずしも全周に亘って一定の幅に形成しなくでもよい。   The outer contour of the outer sheet 66 protrudes from the outer contour of the inner sheet 65 with a predetermined width, and an extension allowance 67 that is continuous over the entire outer periphery of the inner sheet 65 is formed. The extension allowance 67 has a width of about 10 mm to 20 mm, but it does not necessarily have to be formed with a constant width over the entire circumference.

そして、この延出代67とインナーシート65の他面とに粘着手段として両面テープ69,70が貼着されている。この両面テープ69,70の代わりに接着剤を塗布する等してもよい。これにより、インナーシート65とアウターシート66が被断熱部材であるリヤフェンダー29に貼着可能となる。   Then, double-sided tapes 69 and 70 are adhered to the extension allowance 67 and the other surface of the inner sheet 65 as adhesive means. An adhesive may be applied instead of the double-sided tapes 69 and 70. As a result, the inner sheet 65 and the outer sheet 66 can be attached to the rear fender 29 that is a heat-insulated member.

アウターシート66の、インナーシート65が重ね合わせられる部分と延出代67との境界部には複数の欠除部が設けられている。この欠除部は例えば環状縁を有する開口孔(ここでは円孔)72を分散させることにより形成されている。各開口孔72はインナーシート65の外形縁のうち曲率の小さな部分や直線部分に位置するように設けられている。   A plurality of notches are provided at the boundary between the portion of the outer sheet 66 where the inner sheet 65 is overlapped and the extension allowance 67. This notched portion is formed, for example, by dispersing opening holes (here, circular holes) 72 having an annular edge. Each opening hole 72 is provided so as to be located in a portion having a small curvature or a straight portion in the outer edge of the inner sheet 65.

図6に示すように、断熱シート62(63)が両面テープ69,70の粘着力によりリヤフェンダー29に貼着されると、厚みのあるインナーシート65が薄膜状のアウターシート66に包まれる状態となる。そして、アウターシート66に設けられた欠除部としての開口孔72からインナーシート65の外形縁が外気に臨む。   As shown in FIG. 6, when the heat insulating sheet 62 (63) is attached to the rear fender 29 by the adhesive force of the double-sided tape 69, 70, the thick inner sheet 65 is wrapped in the thin film outer sheet 66. It becomes. Then, the outer edge of the inner sheet 65 faces the outside air from the opening hole 72 as a lacking portion provided in the outer sheet 66.

以上のように構成された断熱シート62,63によれば、アウターシート66外周の延出代67がインナーシート65の外形輪郭からはみ出してリヤフェンダー29に貼着されるため、インナーシート65の端面が外部に露呈することがなく、よって高速回転する後輪14から飛散する泥水や小石等が断熱シート62,63に衝突したり、高圧洗車時における水圧が断熱シート62,63に加わってもインナーシート65が剥離することがない。そして、このようにインナーシート65の剥離の懸念がないため、インナーシート65を構成する耐熱材質の厚みを増して耐熱性能を飛躍的に向上させることができる。   According to the heat insulating sheets 62 and 63 configured as described above, the extension allowance 67 on the outer periphery of the outer sheet 66 protrudes from the outer contour of the inner sheet 65 and is attached to the rear fender 29. Is not exposed to the outside, so that muddy water, pebbles and the like scattered from the rear wheel 14 rotating at high speed collide with the heat insulating sheets 62, 63, or even when water pressure during high-pressure car washing is applied to the heat insulating sheets 62, 63 The sheet 65 does not peel off. And since there is no fear of peeling of the inner sheet | seat 65 in this way, the thickness of the heat-resistant material which comprises the inner sheet | seat 65 can be increased, and heat-resistant performance can be improved greatly.

また、アウターシート66に設けた欠除部としての開口孔72からインナーシート65の外形縁が外気に臨むので、断熱シート62,63をリヤフェンダー29に貼着する際にインナーシート65に含まれる空気を開口孔72から脱気しやすく、これにより断熱シート62,63の貼着不良や空気の膨張による剥離を防止できる。しかも、断熱シート62,63の内部に浸入した水分を開口孔72から排出させることができるため、この点でも断熱シート62,63の剥離や劣化を防止することができる。   Further, since the outer edge of the inner sheet 65 faces the outside air from the opening hole 72 as a notch portion provided in the outer sheet 66, it is included in the inner sheet 65 when the heat insulating sheets 62 and 63 are attached to the rear fender 29. Air can be easily degassed from the opening hole 72, thereby preventing the sticking of the heat insulating sheets 62 and 63 and peeling due to air expansion. And since the water | moisture content permeated into the inside of the heat insulation sheets 62 and 63 can be discharged | emitted from the opening hole 72, peeling and deterioration of the heat insulation sheets 62 and 63 can also be prevented also in this point.

開口孔72はアウターシート66の延出代67とインナーシート65との境界部に設けられるため、インナーシート65の変形を許容するものであり、断熱シート62,63を曲面状のリヤフェンダー29にも容易に貼着させることができて剥離もしにくい。   Since the opening 72 is provided at the boundary between the extension allowance 67 of the outer seat 66 and the inner seat 65, the inner seat 65 is allowed to be deformed, and the heat insulating sheets 62 and 63 are attached to the curved rear fender 29. Can be easily attached and is difficult to peel off.

このような断熱シート62,63を、車体内方の熱源(排気装置47)に臨むと同時に外部への開口部(ホイールアーチ)が近接することにより使用条件が最も過酷な場所の一つであるリヤフェンダー29に適用することにより、リヤフェンダー29に信頼性の高い断熱性を付与することができる。そして、例えばリヤフェンダー29と排気装置47との間隔を詰めて車体のコンパクト化にも貢献することができる。   Such heat insulating sheets 62 and 63 face one of the heat sources (exhaust device 47) inside the vehicle body, and at the same time the opening to the outside (wheel arch) is close, so that it is one of the places where the use conditions are the most severe. By applying it to the rear fender 29, the rear fender 29 can be provided with highly reliable heat insulation. Further, for example, the distance between the rear fender 29 and the exhaust device 47 can be reduced, which can contribute to the compactness of the vehicle body.

ところで、図3に示すように、後寄りの断熱シート62,63の延出代67の部分を前寄りの断熱シート61の外縁部の上に重ねて貼着することにより、従来構造の断熱シート61の縁部を延出代67により保護し、断熱シート61のリヤフェンダー29からの剥離を効果的に防止することができる。   By the way, as shown in FIG. 3, the heat insulation sheet of the conventional structure is formed by overlapping and pasting the portion of the extension allowance 67 of the rear heat insulation sheets 62 and 63 on the outer edge of the front heat insulation sheet 61. The edge part of 61 can be protected by the extension allowance 67, and peeling from the rear fender 29 of the heat insulation sheet 61 can be prevented effectively.

なお、リヤフェンダー29のみならず、他のカバー部材にも断熱シート62,63と同様な断熱シートを貼着してもよい。さらに、鞍乗型四輪車両1に限らず自動二輪車や自動車のような他車種および船舶等にも本発明を適用することができる。   Note that a heat insulating sheet similar to the heat insulating sheets 62 and 63 may be attached not only to the rear fender 29 but also to other cover members. Furthermore, the present invention can be applied not only to the straddle-type four-wheel vehicle 1 but also to other vehicle types such as motorcycles and automobiles, ships, and the like.
