Description
【０００１】[0001]
本考案は、自転車のハンドルグリップを覆うようにその前方側に装着し、走行 中に乗車者の手を暖める自転車用防寒器具にかかる、自転車のハンドルグリップ 用カバ−に関するものである。 The present invention relates to a bicycle handlegrip cover, which is attached to a front side of a bicycle handlegrip so as to cover the handlebar, and which covers a bicycle cold weather device that warms a passenger's hand while traveling.
【０００２】[0002]
従来より、実開平２−７５３９１号公報、実開平４−４９５８９号公報等にて 、冬季の手の平を防寒するためにハンドルグリップ自体に発熱体を内蔵して手の 平側から暖めるものや、筒状発熱体をグリップのほぼ全体に内蔵した構造のもの が開示されている。 図５はその例であって、ハンドルバ−１の先端に装着されたハンドルグリップ ２内に発熱体９を埋め込んでなるものである。 Conventionally, in Japanese Utility Model Laid-Open No. 2-75391, Japanese Utility Model Laid-Open No. 4-49589, etc., in order to prevent the palm of the hand from getting cold in the winter, the handle grip itself has a heating element built in to heat it from the palm side. A structure in which a heating element is built into almost the entire grip is disclosed. FIG. 5 shows an example thereof, in which the heating element 9 is embedded in the handle grip 2 attached to the tip of the handle bar-1.
【０００３】[0003]
しかるに、このような従来の技術は、種々の問題点があった。 例えば、グリップ２自体又はグリップ２の表面を暖めるので、手の平側は暖ま るが手の甲側は寒風に曝されて十分な温感が得られないし、グリップ２を全体的 に暖めるので熱効率が悪く、消費電力が大きいという欠点がある。従って、消費 電力が大きいので、人力発電の自転車では温感までに時間を要し実用性に欠ける ということが言われている。 However, such a conventional technique has various problems. For example, since the grip 2 itself or the surface of the grip 2 is warmed, the palm side is warmed, but the back side of the hand is exposed to cold wind, and a sufficient warmth cannot be obtained. It has the drawback of high power consumption. Therefore, since it consumes a large amount of power, it is said that a human-powered bicycle takes time to feel warmth and is not practical.
【０００４】 本考案は、上記したような問題点を解決しようとするものであって、特に、発 熱体の輻射熱によって、手がその甲側から全体的に暖められる自転車のハンドル グリップ用カバ−を提供しようとするものである。The present invention is intended to solve the above-mentioned problems, and in particular, the handle grip cover of a bicycle in which the hand is entirely warmed from the back side by the radiant heat of the heating element. Is to provide.
【０００５】[0005]
従来技術の以上のような問題点を解決するため、本考案は次のような構成を採 用したものである。 即ち、発電機を備えた自転車のハンドルグリップ部において、グリップエンド 側からみた横断面形状がほぼ湾曲状をなし、グリップ部及びブレ−キレバ−を、 覆い隠すように設けたカバ−であって、ハンドルバ−への取付け部であるＵ字状 カラ−部を一体に形成し、当該カバ−本体の内面（グリップ側を向いた面）に発 熱体と、熱線反射層と、断熱層と、を備えたことを特徴とする、自転車のハンド ルグリップ用カバ−にかかるものである。 そして、好ましくは、グリップエンド側からみた横断面形状がほぼ放物線形又 は楕円形であって、その焦点軸近傍にハンドルグリップが位置するように装着さ れた自転車のハンドルグリップ用カバ−にかかる。 In order to solve the above problems of the prior art, the present invention adopts the following configuration. That is, in a handle grip portion of a bicycle equipped with a generator, a cross-sectional shape viewed from the grip end side has a substantially curved shape, and the cover portion is provided so as to cover the grip portion and the break lever. A U-shaped collar portion that is an attachment portion to the handlebar is integrally formed, and a heat generating body, a heat ray reflecting layer, and a heat insulating layer are formed on the inner surface (the surface facing the grip side) of the cover body. The present invention relates to a cover for a handle grip of a bicycle, which is characterized by being provided. And, preferably, the cross-sectional shape viewed from the grip end side is substantially parabolic or elliptical, and the handle grip cover of the bicycle mounted so that the handle grip is located near the focal axis thereof. .
【０００６】 ハンドルグリップ用カバ−は、横断面が放物線形又は楕円形等の湾曲形状をな し、（面）発熱体、熱線反射層、断熱層等を内面側の凹面に支持、固定する骨組 み部である。 そして、走行時に前方から風を受ける外面部は、空気抵抗を減じるために前方 （風上）に向かって凸状の流線形をなし、又、カバ−の外面部の表面は滑らかに 形成したものがよい。かかるハンドルグリップ用カバ−は、一体に形成しやすく 表面が滑らかな射出成形用繊維強化合成樹脂（ＦＲＰ）が材質的に適する。The handle grip cover has a curved cross section such as a parabolic shape or an elliptical shape, and is a skeleton that supports and fixes a (plane) heating element, a heat ray reflection layer, a heat insulation layer, etc. on the inner concave surface. It is only part. The outer surface that receives wind from the front during running has a convex streamline toward the front (upwind) to reduce air resistance, and the surface of the outer surface of the cover is formed smoothly. Is good. For such a handle grip cover, a fiber-reinforced synthetic resin (FRP) for injection molding, which is easy to be integrally formed and has a smooth surface, is suitable as a material.
【０００７】 発熱体としては、好ましくは面発熱体であって、手を暖める熱源の発熱部であ る。従って、熱照射部の面積を広くとるためシ−ト状がよく、上記カバ−本体の 内側に複数個取付ける。そして、発熱部が露出しない構造とし、手が触れても火 傷することがないようにするのが好ましい。特に熱効率の高い遠赤外線発熱体が 適当である。The heating element is preferably a surface heating element and is a heating portion of a heat source for warming the hand. Therefore, since the area of the heat radiating portion is wide, the sheet shape is good, and a plurality of sheets are attached inside the cover body. Further, it is preferable that the heat generating portion is not exposed so as not to be burned even if it is touched by the hand. Far-infrared heating elements with high thermal efficiency are particularly suitable.
【０００８】 又、熱線反射層は上記発熱体から放射される熱線が、裏側のカバ−本体側に逃 げるのをできるだけ防止すると共に、発熱体及びグリップ部の手から放射される 熱線を反射し、手に熱を集中させるために設けた金属製（又はメッキされた）の 薄板部材である。特に熱反射性の高いアルミニウム蒸着品や光沢メッキ品が耐熱 性も高く適当である。The heat ray reflection layer prevents heat rays emitted from the heating element from escaping to the cover body side on the back side as much as possible, and reflects the heat rays emitted from the hands of the heating element and the grip portion. However, it is a thin plate member made of metal (or plated) for concentrating heat on the hand. In particular, aluminum vapor-deposited products and gloss-plated products, which have high heat reflectivity, are suitable because they have high heat resistance.
【０００９】 更に、断熱層は上記カバ−本体と熱線反射層との間に挟まれるもので、熱伝導 率の低いガラスやセラミック系の繊維をシ−ト状に成形したものが耐熱性が高く 好ましい部材である。又、ウレタン発泡成形品は断熱効果が高いという特徴があ り、これも又好適な材料である。Further, the heat insulating layer is sandwiched between the cover body and the heat ray reflecting layer, and a sheet made of glass or ceramic fiber having a low thermal conductivity has a high heat resistance. It is a preferable member. Further, the urethane foam-molded product is characterized by having a high heat insulating effect, which is also a suitable material.
【００１０】[0010]
本考案は、グリップ部及びブレ−キレバ−を、覆い隠すように設けたカバ−本 体の内面に発熱体と、熱線反射層と、断熱層と、を備えたものであって、特にカ バ−本体の横断面形状を放物線又は楕円形状に形成し、その内面側に発熱体と熱 反射層と断熱層とを設け、更に、グリップに向かって集中的に熱が集められるた め、冬季寒風下走行時にも手全体を暖めて快適に自転車を使用するための自転車 のハンドルグリップ用カバ−を提供するものである。 The present invention comprises a heating element, a heat ray reflecting layer, and a heat insulating layer on the inner surface of the cover body which is provided so as to cover the grip portion and the breaker lever, and in particular, the cover is provided. -The body is formed in a parabolic or elliptical cross-section, and a heating element, a heat reflection layer, and a heat insulation layer are provided on the inner surface side of the body. It is intended to provide a cover for a handlebar of a bicycle, which warms up the entire hand and allows the bicycle to be used comfortably even when traveling downhill.

以下本考案を図面をもって更に詳細に説明する。 図１は、本考案の一例を示す全体斜視図である。 図中、１はハンドルバ−であり、この両端部にハンドルグリップ２が装着され る。そして、ハンドルグリップ用カバ−３をハンドルグリップ２及びブレ−キレ バ−４を覆ってハンドルバ−１に取り付けられている。５はＵ字状カラ−部であ り、ハンドルグリップ用カバ−３と一体に形成され、取付金具６よってハンドル バ−１に取り付けられる。 Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is an overall perspective view showing an example of the present invention. In the figure, 1 is a handlebar, and handlebar grips 2 are attached to both ends thereof. A handle grip cover 3 is attached to the handle bar 1 so as to cover the handle grip 2 and the brake lever-4. Reference numeral 5 is a U-shaped collar portion, which is formed integrally with the handle grip cover 3 and is attached to the handlebar 1 by a mounting bracket 6.
【００１２】 図２は図１の断面拡大図であり、図３は、カバ−部の一部拡大図である。 図示したように、ハンドルグリップ２の前方側にて、ハンドルグリップ２及び ブレ−キレバ−４を覆い隠すようにハンドルバ−１にハンドルグリップ用カバ− ３が取り付けられる。このハンドルグリップ用カバ−３は、ＦＲＰ製品であり、 前記のＵ字状カラ−部５を一体に形成し、更に、横断面が放物線形をもつ湾曲形 状３1 をなし、走行時に前方から風を受ける外面部３2 は、空気抵抗を減じるた めに前方（風上）に向かって凸状の流線形をなしている。 このハンドルグリップ用カバ−３における湾曲形状３1 は、後述する熱線をハ ンドルグリップ２に集中するためのものである。FIG. 2 is an enlarged sectional view of FIG. 1, and FIG. 3 is a partially enlarged view of the cover portion. As shown in the figure, a handle grip cover 3 is attached to the handle bar 1 so as to cover the handle grip 2 and the break lever 4 on the front side of the handle grip 2. This cover 3 for handle grip is an FRP product, which is integrally formed with the above-mentioned U-shaped collar portion 5 and further has a curved shape 3 1 having a parabolic cross-section, which is used from the front during running. outer surface portion 3 2 which receives the wind forms a convex streamlined in order to reduce the air resistance toward the front (upwind). Curved shape 3 1 in cover -3 for the handle grip is for concentrating the heat rays to be described later Ha nd dollars grip 2.
【００１３】 さて、ハンドルグリップ用カバ−３の湾曲形状３1 面に先ず断熱層７が添着さ れる。 この断熱層７は、耐熱性の高いセラミック系の繊維をシ−ト状に成形したもの を用いたが、これに断熱効果の高いウレタン発泡成形品を更にもちいて二層構造 にすれば、より断熱効果が向上し、カバ−３側に伝わる熱量を更に減らせること は言うまでもない。[0013] Now, first, the heat insulating layer 7 is affixed to a curved shape 3 1 side of the handle gripping cover -3. The heat insulating layer 7 is formed by forming a sheet of ceramic fiber having high heat resistance into a sheet, but if a urethane foam molded article having a high heat insulating effect is further used to form a two-layer structure, it is more effective. It goes without saying that the heat insulating effect is improved and the amount of heat transferred to the cover-3 side can be further reduced.
【００１４】 この断熱層７上に熱線反射層８を形成する。ここではアルミニウム蒸着品をも ちいた。この熱線反射層８は、後述する（面）発熱体から放射される熱線が、裏 側のカバ−３側に逃げるのを防止すると共に、面発熱体及びグリップ部の手から 放射される熱線を反射し、手に熱を集中させるために設けたものである。The heat ray reflective layer 8 is formed on the heat insulating layer 7. Here, aluminum vapor deposition products were used. The heat ray reflection layer 8 prevents heat rays radiated from a (surface) heating element described later from escaping to the cover-3 side on the back side, and at the same time prevents the heat rays radiated from the surface heating element and the hand of the grip portion. It is provided to reflect and concentrate heat on the hand.
【００１５】 特に、手を暖める熱源の発熱部９は面発熱体が好ましく、熱照射部の面積を広 くとるためシ−ト状をなし、上記カバ−３の内側に複数個取付けられている。特 に好ましくは、熱効率の高い遠赤外線発熱体が適する。In particular, the heat generating portion 9 of the heat source for warming the hand is preferably a surface heating element, and has a sheet shape in order to increase the area of the heat radiating portion, and a plurality of heat generating portions are attached inside the cover-3. . Particularly preferably, a far-infrared heating element having high thermal efficiency is suitable.
【００１６】 図４は本考案の電熱装置としての回路ブロック図である。 図中、１１は発電機であり、面発熱体、制御部等の回路素子の電源となる。１ ２は整流回路であり、当該整流回路を介して二次電池１３を充電する。この二次 電池１３は走行停止中の一時電源となる。１４はスイッチ、１５はポジスタであ り、面発熱体９の温度制御用回路素子である。このポジスタ１５は温度が上昇す ると抵抗値も上昇するという特性を有する。１６は保護用ダイオ−ド、１７は制 御用トランジスタ−、１８は面発熱体部のリレ−（スイッチ）である。FIG. 4 is a circuit block diagram as an electric heating device of the present invention. In the figure, 11 is a generator, which serves as a power source for circuit elements such as a surface heating element and a control unit. A rectifier circuit 12 charges the secondary battery 13 through the rectifier circuit. The secondary battery 13 serves as a temporary power source while the vehicle is stopped. A switch 14 and a posistor 15 are circuit elements for controlling the temperature of the surface heating element 9. The posistor 15 has a characteristic that the resistance value also rises as the temperature rises. Reference numeral 16 is a protection diode, 17 is a control transistor, and 18 is a relay (switch) for the surface heating element.
【００１７】 さて、図４に示す制御回路の作用を説明すると、スイッチ１４を閉じるとトラ ンジスタ−１７が導通し、リレ−１８が作動しリレ−接点が閉じ発電機１１の出 力により面発熱体９が発熱する。 又、カバ−３の温度が所定値より上昇した場合は、カバ−３に設けてあるポジ スタ１５の抵抗値が上昇してリレ−１８を駆動しているトランジスタ１７が不導 通となり、リレ−接点が開き面発熱体９への電力供給が中止される。 その後、カバ−３の温度が下がれば、ポジスタ１５の抵抗が低下し再びトラン ジスタ１７が導通状態となり、リレ−接点が閉じて面発熱体９が発熱する。The operation of the control circuit shown in FIG. 4 will be described. When the switch 14 is closed, the transistor 17 becomes conductive, the relay 18 operates, the relay contact closes, and the output of the generator 11 causes surface heat generation. The body 9 generates heat. When the temperature of the cover-3 rises above a predetermined value, the resistance value of the posistor 15 provided in the cover-3 rises and the transistor 17 driving the relay 18 becomes non-conductive, and the relay 17 becomes non-conductive. -The contacts open and the power supply to the surface heating element 9 is stopped. Then, when the temperature of the cover 3 decreases, the resistance of the posistor 15 decreases, the transistor 17 becomes conductive again, the relay contact closes, and the surface heating element 9 generates heat.
【００１８】[0018]
上記に示す構成により本考案は次のような効果がある。 発熱体の輻射熱によって、手がその甲側から全体的に暖められるためソフトな 暖かさが感じられ、熱線反射層表面によって、手から放射された熱線が手に戻っ て手に再吸収されるので、熱効率が高いものである。 そして、ハンドルグリップが当該カバ−（横断面）の焦点軸近傍に配置される ように、当該カバ−をハンドルバ−に取り付けているので、発熱体や手から放射 される熱線が効率よく手に集中し熱効率が高い。 The present invention having the above-mentioned configuration has the following effects. The radiant heat of the heating element heats the hand as a whole from the back side of the hand, making it feel soft, and the surface of the heat ray reflection layer returns the heat rays emitted from the hands to the hands and reabsorbs them. , High thermal efficiency. Since the cover is attached to the handlebar so that the handle grip is located near the focal axis of the cover (cross section), heat rays radiated from the heating element or the hand are efficiently concentrated on the hand. The heat efficiency is high.
【００１９】 又、当該カバ−の（横断面）形状が放物線や楕円形状の流線形であるので、走 行方向から受ける風による空気抵抗は小さい。そのため、当該カバ−を取り付け ることによる自転車乗車時の走行抵抗は無視できる。そして、寒風に直接手が曝 されることがないので、冬季でも比較的快適に自転車を使用できる。Further, since the (transverse cross section) shape of the cover is a parabolic or elliptical streamline, air resistance due to wind received from the running direction is small. Therefore, the running resistance when riding the bicycle due to the installation of the cover can be ignored. Moreover, since the hands are not directly exposed to the cold wind, the bicycle can be used relatively comfortably even in winter.
