【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、家庭の芝刈に適するバリカン式の電気芝刈
機に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a clipper-type electric lawn mower suitable for lawn mowing at home.
家庭の庭芝は大部分が大スペースではないため、バリカ
ン式の電気芝刈機が多く用いられている。この電気芝刈
機は、ハウジング内にモータと減速ギアと偏心カムを設
け、モータ回転時偏心カムの回転で可動刃を揺動せし
め、ハウジングに固定された固定刃との間で芝を刈るも
のであり、固定刃はハウジングに４個所のネジで固着す
る構造が一般的である。Most garden turf at home is not in a large space, so a clipper-type electric lawn mower is often used. This electric lawn mower is provided with a motor, a reduction gear and an eccentric cam in the housing, and the movable blade is swung by the rotation of the eccentric cam when the motor is rotating, so that the lawn is cut between the fixed blade fixed to the housing. The fixed blade is generally fixed to the housing with four screws.
この種芝刈機は、狭い庭や、縁刈りに便利なため重宝で
あるが、芝刈時に発生する草葉や、砂、ホコリがハウジ

都度４個所止めのネジを外して刃を取り外し、内部の掃
除をする煩わしさがあった。また刃先の研磨や固定刃・
可動刃ユニットを交換する時も同様な煩わしさがあっ
た。This type of lawn mower is useful because it is convenient for narrow gardens and edging, but grass, sand, and dust generated during lawn mowing intrude into the housing, which requires cleaning. It was troublesome to clean the inside by removing the screws for fixing points and removing the blade. In addition, polishing the blade edge and fixed blades
There was a similar trouble when replacing the movable blade unit.
本考案は上記課題を解決するため、ネジ止めをしないで
刃の脱着を行うようにしたものである。In order to solve the above problems, the present invention is designed such that the blade is attached and detached without screwing.
即ち、モータ１を内装するハウジング２の底部に、固定
刃３を嵌着するスライド溝2aを設け、固定刃３の端部に
透孔3aを設け、該透孔3a方向にバネ５で付勢するピン４

を中心に揺動自在に可動刃６を取付け、且可動刃６の端
部Ｂに開口８を設け、該可動刃６の開口８はモータ１で
回転する偏心カム９にのぞましめ、固定刃３をスライド
溝2aに嵌着時、モータ１で回転する偏心カム９は可動刃
６の開口８内に位置せしめ、可動刃６を揺動する電気芝
刈機としたものである。That is, a slide groove 2a into which a fixed blade 3 is fitted is provided at the bottom of a housing 2 that houses the motor 1, a through hole 3a is provided at the end of the fixed blade 3, and a spring 5 biases the through hole 3a in the direction of the through hole 3a. Pin 4
Is installed in a proper place in the housing 2, while the fixed blade 3 has an axis A
A movable blade 6 is swingably mounted around the movable blade 6, and an opening 8 is provided at an end B of the movable blade 6. The opening 8 of the movable blade 6 is fixed to an eccentric cam 9 rotated by a motor 1. When the blade 3 is fitted in the slide groove 2a, the eccentric cam 9 rotated by the motor 1 is positioned in the opening 8 of the movable blade 6, and the movable blade 6 is swung to function as an electric lawn mower.
固定刃３をハウジング２の底部に設けたスライド溝2aに
挿入嵌着し、バネ５で飛び出しているピン４を鉛筆など
の先で押して固定刃３の進行を妨げないようにしてか
ら、固定刃３をスライド溝2aの奥まで挿入すると、ピン
４はバネ５の力で固定刃３の透孔3aに突出し、固定刃３
の抜け止めとなる。The fixed blade 3 is inserted and fitted into the slide groove 2a provided on the bottom of the housing 2, and the pin 4 protruding by the spring 5 is pushed with a tip of a pencil or the like so as not to hinder the movement of the fixed blade 3. 3 is inserted into the slide groove 2a, the pin 4 projects into the through hole 3a of the fixed blade 3 by the force of the spring 5, and the fixed blade 3
It will prevent it from slipping out.
固定刃３を取り外したい時は、上記順序と逆にピン４を
押して透孔3aから没した状態にしてから、固定刃３をス
ライド溝2aに沿って外ずす方向へ引けば、スライド溝2a
から固定刃は外れる。When you want to remove the fixed blade 3, reverse to the above order, push the pin 4 to make it sink into the through hole 3a, and then pull the fixed blade 3 along the slide groove 2a in the direction to slide it out.
The fixed blade comes off.
固定刃３には可動刃６が軸Ａで取付けられているが、可
動刃６の端部Ｂは開口８が形成しているので、固定刃３
をスライド溝2aに装着しても、モータ１で回転する偏心
カム９は開口８内に収まるものである。The movable blade 6 is attached to the fixed blade 3 by the axis A, but since the opening 8 is formed at the end B of the movable blade 6, the fixed blade 3 is attached.
Even if is mounted in the slide groove 2a, the eccentric cam 9 rotated by the motor 1 can be accommodated in the opening 8.
固定刃３をスライド溝2aに嵌着後は、スイッチ操作でモ
ータ１を回転させれば、減速ギアを介して偏心カム９が
回転し、嵌合する開口８が偏心カム９によって駆動さ
れ、可動刃６も揺動するから、芝草が固定刃３と可動刃
６の切刃の間にて刈り取られるものである。After the fixed blade 3 is fitted in the slide groove 2a, if the motor 1 is rotated by a switch operation, the eccentric cam 9 rotates via the reduction gear, and the fitting opening 8 is driven by the eccentric cam 9 to move. Since the blade 6 also swings, the grass is cut off between the fixed blade 3 and the movable blade 6.

心カム９の凸部は抵抗なく開口８に納まる。The configuration will be described below with reference to the drawings showing an embodiment. 1 is a motor housed in a housing 2, 3 is a fixed blade fitted in a slide groove 2a provided at the bottom of the housing 2, and 3a is an end of the fixed blade 3. Through holes 4 provided in the portion are pins which are constantly pushed up by a spring 5, and when the fixed blade 3 is fitted in the slide groove 2a, the pins 4 engage with the through holes 3a. 6 is a movable blade attached to the fixed blade 3 by the axis A, 8 is an opening provided at the end B of the movable blade 6, 7 is a reduction gear that slows down the rotation of the motor 1, and 9 is geared with the reduction gear 7 around the periphery. It is an eccentric cam that forms a gear, and has a convex portion that reaches the fixed blade 3. When the fixed blade 3 is inserted and fitted in the slide groove 2a, if the positional relationship between the fixed blade 3 and the movable blade 6 is set in advance so as to match the convex portion of the eccentric cam 9, the convex portion of the eccentric cam 9 will have resistance. Fits in the opening 8 instead.

との間で芝草を刈取るものである。Reference numeral 10 is an operation switch, and 11 is a power cord. When the operation switch 10 is closed, the motor 1 rotates and the eccentric cam 9 slowly rotates via the reduction gear 7. Since the convex portion of the eccentric cam 9 is fitted in the opening 8 of the movable blade 6, when the eccentric cam 9 rotates, the opening 8 portion is swung by the eccentric cam 9, and the movable blade 6 is fixed on the axis A. Since the movable blade 6 is attached to the blade 3, the blade edge of the movable blade 6 makes an oscillating motion, and the lawn grass is mowed with the blade edge of the fixed blade 3.
以上のような構成、作用を有する本考案は、刃の脱着を
一々ネジなどを用いないで行うことが出来るものであ
り、ピンとバネの作用で刃が容易に抜けることがないも
のである。According to the present invention having the above-described structure and operation, the blade can be attached and detached without using any screws or the like, and the blade does not easily come off due to the action of the pin and the spring.
従って刃の内側に芝などが入っても、道具を用いないで
取り外しが容易であるから、気楽に掃除が行えるもので
ある。Therefore, even if turf or the like enters the inside of the blade, it can be easily removed without using a tool, so that cleaning can be performed easily.
