Description

本発明は、櫛歯状の一対の刃を相対的に摺接させることで毛の切断を行うバリカンに関するものである。   The present invention relates to a hair clipper that cuts hairs by relatively sliding a pair of comb-shaped blades.

バリカンにおける刃は、一般的には固定刃と往復駆動される可動刃とからなる櫛歯状の一対の刃で構成され、櫛歯状の部分における溝に導入した毛を櫛歯状の部分における側縁で切断するものである。このために、櫛歯状の一対の刃は、特開平10−127961号公報(特許文献1)などに示されているように、相対的に摺接する構成となっているわけであるが、切れ味の向上等を求めて上記相対摺接速度を速めた時、摺接部の摩擦による発熱が問題となる。発熱で刃の温度が上昇して刃が接する肌に熱さを感じさせることになるためである。   The blade in the clipper is generally composed of a pair of comb-shaped blades composed of a fixed blade and a movable blade that is driven to reciprocate, and the hair introduced into the grooves in the comb-shaped portion is formed in the comb-shaped portion. Cut at the side edge. For this reason, the pair of comb-shaped blades are configured to be relatively slidable as shown in Japanese Patent Application Laid-Open No. 10-127961 (Patent Document 1). When the relative sliding contact speed is increased in order to improve the above, etc., heat generation due to friction of the sliding contact portion becomes a problem. This is because the temperature of the blade rises due to heat generation and the skin touched by the blade feels hot.

このような温度上昇を防ぐものとして、特開2003−126571号公報(特許文献2)には、刃の駆動用のモータに内蔵させたファンによる送風で冷却を行うものが提案されている。モータを内蔵するハウジングの外周部に設けた送風口から刃が位置する前端に向けて送風を行う上記公報に記載のものでは、羊毛などを刈り取るための動物用バリカンとしては問題はなくとも、人体の頭髪などをカットするためのものとしては、刈った毛が送風によって飛散することが問題となる。また、送風はハウジングの外面を流れるために、ハウジング内のモータの回転を往復運動に変換する部分に熱が溜まりやすく、これ故に冷却効率もさほど高くない。
特開平10−127961号公報 特開2003−126571号公報
In order to prevent such a temperature rise, Japanese Patent Application Laid-Open No. 2003-126571 (Patent Document 2) proposes cooling by blowing air from a fan built in a blade driving motor. The thing described in the above publication that blows air from the blower opening provided in the outer peripheral portion of the housing containing the motor toward the front end where the blade is located is not a problem as an animal clipper for cutting wool or the like. As a thing for cutting the head hair etc., it is a problem that the cut hair scatters by ventilation. Further, since the air flows through the outer surface of the housing, heat is likely to accumulate in a portion where the rotation of the motor in the housing is converted into a reciprocating motion, and therefore the cooling efficiency is not so high.
JP 10-127961 A JP 2003-126571 A

本発明は上記の従来の問題点に鑑みて発明したものであって、摩擦熱による刃の温度上昇を効果的に且つ他の問題を招くことなく抑制することができるバリカンを提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a clipper capable of effectively suppressing the temperature rise of the blade due to frictional heat without causing other problems. It is what.

上記課題を解決するために本発明に係るバリカンは、先端が櫛歯状に形成されている一対の刃と、これら一対の刃を相対的に摺接させる駆動手段とを備えたバリカンであり、上記一対の刃のうちの往復駆動される刃の駆動方向両端近傍位置に、フィンを立設しているとともに、刃が装着されたハウジングは、フィンの往復動方向の延長線上付近にスリットを備えていることに特徴を備えている。 In order to solve the above problems, a clipper according to the present invention is a clipper provided with a pair of blades whose tips are formed in a comb-like shape, and a driving means for relatively slidingly contacting the pair of blades. Of the pair of blades, fins are erected in the vicinity of both ends in the drive direction of the reciprocating blade, and the housing on which the blades are mounted has a slit in the vicinity of the extended line in the reciprocating direction of the fin. It has a feature in being.

刃が往復駆動される時、上記フィンが風を起こして内部に溜まった空気をハウジング外に放出するために、刃の温度上昇が防止されるものであり、この時、ハウジングに設けたスリットのためにフィンによる内部空気の放出をより効果的に行うことができるWhen the blades are driven back and forth, the fins generate wind and the air accumulated inside is released to the outside of the housing, so that the temperature of the blades is prevented from rising . Therefore, the internal air can be released more effectively by the fins .

上記フィンは、刃に直接形成するほか、モータの回転運動を往復運動に変換するための部材で且つ刃に取り付けられる部材に設けてもよい。   In addition to forming the fin directly on the blade, the fin may be provided on a member for converting the rotational motion of the motor into a reciprocating motion and attached to the blade.

上記フィンは刃の往復動方向にほぼ直交する方向に長いものとして形成したものや、往復動方向に斜交するものを好適に用いることができる。   As the fins, those formed long in a direction substantially perpendicular to the reciprocating direction of the blade and those oblique to the reciprocating direction can be suitably used.

本発明は、刃の摩擦熱で加熱された刃付近の内部空気が、往復駆動される刃に設けたフィンで起こされる風でハウジング外にスリットを通じて効果的に放出されるために、刃の温度上昇が抑えられるものであり、しかも回転駆動されるファンを用いて冷却する場合のような刈った毛が飛散してしまうという問題を招くこともない。 In the present invention, since the internal air in the vicinity of the blade heated by the frictional heat of the blade is effectively discharged through the slit to the outside of the housing by the wind generated by the fin provided on the reciprocating blade, the temperature of the blade The rise is suppressed, and there is no problem that the cut hair is scattered as in the case of cooling using a fan that is driven to rotate.

以下、本発明を添付図面に示す実施形態に基いて説明すると、図2に示すように、このバリカン4は、モータ(図示せず)を内蔵する本体部5と、本体部5の前端に着脱自在に装着される刃ブロック3とからなるもので、刃ブロック3は共に前端が櫛歯状に形成されている固定刃1及び可動刃2と、固定刃1が固定される固定板11と、可動刃2上に固定された案内板12と、案内板12を介して可動刃2を固定刃1に押さえつけている押さえばね14とからなるもので、上記案内板12はその幅方向中央部にカム溝13(図4参照)を備えている。上記モータによって回転駆動される偏心軸(図示せず)がカム溝13に係合することで、モータの回転運動が可動刃2の往復直線運動に変換されるものである。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. As shown in FIG. 2, the clipper 4 is attached to and detached from a main body 5 containing a motor (not shown) and a front end of the main body 5. The blade block 3 includes a blade block 3 that is freely mounted. The blade block 3 includes a fixed blade 1 and a movable blade 2 each having a front end formed in a comb-tooth shape, a fixed plate 11 on which the fixed blade 1 is fixed, The guide plate 12 includes a guide plate 12 fixed on the movable blade 2 and a pressing spring 14 that presses the movable blade 2 against the fixed blade 1 via the guide plate 12. The guide plate 12 has a central portion in the width direction. A cam groove 13 (see FIG. 4) is provided. An eccentric shaft (not shown) that is rotationally driven by the motor engages with the cam groove 13 so that the rotational motion of the motor is converted into a reciprocating linear motion of the movable blade 2.

また、上記可動刃2は、固定刃1に対して往復動方向においてスライド自在となっているだけでなく、刈り高さの調節を可能とするために前後方向においてもスライド自在に保持されて、本体部5からの操作によって上記押さえばね14を介して可動刃2を前後方向にスライドさせることができるようになっているのであるが、ここでは前後スライドに関する構成の説明は省略する。   The movable blade 2 is not only slidable in the reciprocating direction with respect to the fixed blade 1, but is also slidably held in the front-rear direction in order to enable adjustment of the cutting height. Although the movable blade 2 can be slid in the front-rear direction via the pressing spring 14 by an operation from the main body 5, the description of the configuration related to the front-rear slide is omitted here.

なお、図1及び図3で示す可動刃2は前方側に移動して固定刃2との摺接面積が最も大きくなっている状態を、つまりは可動刃2の往復動時の摩擦による発熱が最も多くなっている状態を示している。   The movable blade 2 shown in FIGS. 1 and 3 moves forward and has the largest sliding contact area with the fixed blade 2, that is, heat generated by friction during the reciprocating motion of the movable blade 2. It shows the state that is the most.

そして、往復駆動されることで固定刃1に摺接する可動刃2は、その往復動方向の両端部近傍位置に、夫々フィン6を備えている。図示例では案内板12の前端両側縁から立設されたものとして形成されている上記フィン6は、可動刃2の往復動方向にほぼ直交する前後方向に長く且つ後端側が往復動方向と斜交するように傾斜しており、このために可動刃2が往復動を行う時、フィン6は風を起して内部の空気を本体部5の外殻及び刃ブロック3の固定板11で構成されるハウジング外に放出する。ハウジングの側面に形成した図3に示すスリット16は、フィン6が起こす風を抵抗なく通過させるためのもので、ハウジング前端と可動刃2との間の隙間に加えてフィン6の往復動方向の延長線上付近に上記スリット16が存在することで、内部空気の放出がより効果的になされるようになっている。   The movable blades 2 that are in sliding contact with the fixed blade 1 by being reciprocated are provided with fins 6 at positions near both ends in the reciprocating direction. In the illustrated example, the fin 6 formed as standing from both side edges of the front end of the guide plate 12 is long in the front-rear direction substantially orthogonal to the reciprocating direction of the movable blade 2 and the rear end side is inclined with respect to the reciprocating direction. For this reason, when the movable blade 2 reciprocates, the fins 6 generate wind and the internal air is constituted by the outer shell of the main body 5 and the fixed plate 11 of the blade block 3. Discharged out of the housing. The slit 16 shown in FIG. 3 formed on the side surface of the housing is for allowing the wind generated by the fin 6 to pass through without resistance. In addition to the gap between the front end of the housing and the movable blade 2, the slit 6 in the reciprocating direction of the fin 6 is provided. Due to the presence of the slit 16 in the vicinity of the extension line, the internal air can be released more effectively.

なお、案内板12の幅方向中央部に位置するカム溝13部分の壁面も可動刃2の往復動時に風を起こすことになるが、ハウジングの内面との距離が遠い位置にあるために、内部空気を外部に放出して刃の温度上昇を防ぐという点においては、殆ど機能しない。   The wall surface of the cam groove 13 located at the center in the width direction of the guide plate 12 also generates air when the movable blade 2 is reciprocated. However, since the distance from the inner surface of the housing is far away, It hardly functions in that air is discharged outside to prevent the blade temperature from rising.

ちなみに、フィン6の高さHを1mm、ハウジング前端と可動刃2との間の隙間及びスリット16の幅Wを1mmとした時、図示例のバリカンでは、フィン6を設けていないものに比して、肌に接することになる固定刃1の温度が5℃以上低くなり、このために固定刃1が肌に接しても熱いと感ずることはなかった。   By the way, when the height H of the fin 6 is 1 mm, the gap between the front end of the housing and the movable blade 2 and the width W of the slit 16 are 1 mm, the clipper in the illustrated example is compared to the case where the fin 6 is not provided. Thus, the temperature of the fixed blade 1 that comes into contact with the skin was lowered by 5 ° C. or more. Therefore, even if the fixed blade 1 was in contact with the skin, it was not felt that it was hot.

フィン6は往復動を行う関係で、その長手方向が往復動方向とほぼ直交する前後方向となるようにしておくことが好ましいが、一部が往復動方向と斜交したり、図6に示すように全体が斜交しているものであってもよい。斜交角度に応じて、フィン6で起こされる風が出て行く方向が変化することになるが、ハウジング16の側面にスリット16を形成する場合、往復動方向にほぼ直交するフィン6が温度上昇の防止の点で効果的であった。   Since the fin 6 reciprocates, it is preferable that the longitudinal direction thereof is the front-rear direction substantially orthogonal to the reciprocating direction. However, a part of the fin 6 obliquely crosses the reciprocating direction, as shown in FIG. As shown in FIG. Depending on the oblique angle, the direction in which the wind generated by the fins 6 changes changes. However, when the slit 16 is formed on the side surface of the housing 16, the temperature of the fins 6 almost perpendicular to the reciprocating direction increases. It was effective in terms of prevention.

また、図示例では樹脂成形品である案内板12にフィン6を設けることで、部品点数の増加を招くことなくフィン6を設けることができるようにしているが、金属板である可動刃2からの切り起こしやアウトサート成形によって可動刃2に直接フィン6を設けてもよいものである。   In the illustrated example, the fin 6 is provided on the guide plate 12 which is a resin molded product so that the fin 6 can be provided without increasing the number of parts. However, from the movable blade 2 which is a metal plate. The fins 6 may be provided directly on the movable blade 2 by cutting and raising or outsert molding.
