本考案は例えば手押しによつて走行せしめる芝
刈機のハウジング構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing structure for a lawn mower that is driven, for example, by hand.
一般に芝刈機のブレードは地面に対し1゜30′程
度前傾せしめることが、芝をむらなく刈り取る上
で好ましく、一方芝刈作業中に石などの障害物が
芝刈機のブレードに当たらないように、最近では
ブレードを収納するハウジングの下端をブレード
よりも下方に位置せしめて、石などをハウジング
下端によつて除くようにしている。 In general, it is preferable to tilt the lawn mower blade approximately 1°30' forward relative to the ground in order to mow the lawn evenly. Recently, the lower end of the housing that houses the blade is positioned below the blade so that stones and the like can be removed by the lower end of the housing.
ところで、ブレードとハウジング下端とは一般
に平行となるように設定されるため、上記の如く
前傾したブレードを収納するハウジングの下端は
たとえブレードよりも下方に位置せしめたとして
も、後方が上がつて地面との隙間が大きくなるた

解消するにはハウジング下端をブレードと平行と
せず地面と平行とすればよいのであるが、このよ
うにすると、走行に伴うハウジング下端と芝草と
のフリクシヨンが大きくなり、手押し荷重が大き
くなる不利がある。 By the way, the blade and the lower end of the housing are generally set to be parallel, so even if the lower end of the housing housing the blade that is tilted forward as described above is positioned below the blade, the rear end will rise. Because the gap between it and the ground becomes larger, it is possible that stones and other objects could get in. To solve this problem, the lower end of the housing could be made parallel to the ground instead of parallel to the blade, but this would have the disadvantage of increasing the friction between the lower end of the housing and the grass as it travels, and increasing the hand-holding load. There is.
本考案は走行に伴うフリクシヨンは主に走行方
向と直交するハウジング下端と芝草との間で発生
し、走行方向と略一致するハウジング側部下端と
芝草との間で発生するフリクシヨンは小さい点に
着目して本考案を成したものであり、その目的と
する処は、作業中に石などの障害物がブレードに
当たることを有効に防止でき、且つ走行に伴う荷
重を軽くし得る芝刈機のハウジング構造を提供す
るにある。 This invention focuses on the fact that the friction that occurs during driving mainly occurs between the lower end of the housing that is perpendicular to the running direction and the grass, and that the friction that occurs between the lower end of the housing side that is approximately in line with the running direction and the grass is small. The purpose of this invention is to provide a housing structure for a lawn mower that can effectively prevent obstacles such as stones from hitting the blade during operation, and that can reduce the load associated with running. is to provide.
斯る目的を達成すべく本考案は、前傾したブレ
ードを収納するハウジングの側部下端をブレード
よりも下方に位置せしめるとともに地面と平行と
し、且つハウジング後部の仕切板の下端をハウジ
ング側部下端よりも上方に位置せしめたことを構
成上の特徴とする。 In order to achieve such an objective, the present invention has the lower end of the side of the housing that accommodates the forward-inclined blade positioned below the blade and parallel to the ground, and the lower end of the partition plate at the rear of the housing is positioned below the lower end of the side of the housing. A structural feature is that it is located above the
以下に本考案の実施例を添付図面に基づいて説
明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
第1図は手押しによつて走行せしめられる芝刈
機の一部を破断して示した側面図、第2図は同芝
刈機の底面図である。 FIG. 1 is a partially cutaway side view of a lawn mower that is driven by hand, and FIG. 2 is a bottom view of the lawn mower.
芝刈機1はアルミニウム合金などを一体的に成
形してなるハウジング2上にエンジン3が載置さ

左右一対のハンドル4,4が延出され、これらハ
ンドル4,4間に刈り取つた芝を収納するグラス
バツク5が取り付けられる。 In the lawn mower 1, an engine 3 is mounted on a housing 2 integrally formed of aluminum alloy or the like. A pair of left and right handles 4, 4 extend diagonally rearward from the rear of the housing 2, and a grass bag 5 for storing cut grass is attached between these handles 4, 4.
一方、ハウジング2にはブレード6を囲むスク
ロール部7が形成され、このスクロール部7の側

の駆動軸10は垂直方向に対し、約1゜30′傾斜し
ている。したがつてブレード6は約1゜30′前傾し
て保持され、ブレード6とハウジング2の側部下
端8とは平行となつていない。 On the other hand, a scroll portion 7 surrounding the blade 6 is formed in the housing 2, and a lower side end 8 of the scroll portion 7, that is, a lower side end 8 of the housing 2 is parallel to the ground G and located below the blade 6. ing. Further, the blade 6 is attached to a blade holder 9.
The drive shaft 10 of the engine 3 is fixed to the drive shaft 10 of the engine 3 through the drive shaft 10, and the drive shaft 10 is inclined at an angle of about 1°30' with respect to the vertical direction. The blade 6 is therefore held tilted forward by approximately 1° 30', and the blade 6 and the lower lateral end 8 of the housing 2 are not parallel.
また、ハウジング2の後部下面には仕切板11
が設けられる。この仕切板11の下端12は内方
に折曲しており、且つハウジング2の側部下端8
よりも上方でブレード6の後端よりも下方に位置
している。 In addition, a partition plate 11 is provided on the rear lower surface of the housing 2.
will be provided. The lower end 12 of this partition plate 11 is bent inward, and the side lower end 8 of the housing 2
It is located above the blade 6 and below the rear end of the blade 6.
以上において、ハンドル4を握り、ハンドル4

リクシヨンは僅かであり、走行を妨げることはな
い。 In the above, grip the handle 4 and
The lawn mower 1 is pushed forward and run while rotating the blade 6 by tilting the operating lever 13 provided at the front forward. Then, since the lower side end 8 of the housing 2 is parallel to the ground below the blade 6, obstacles such as pebbles can be prevented from entering the scroll part 7. Even if the lower side end 8 of the housing 2 Even if a pebble shorter than the gap between the housing 2 and the ground G enters, the blade 6 will not be damaged because the blade 6 is located above the side lower end 8 of the housing 2. Here, since the lower end of the side of the housing 2 is substantially along the running direction of the lawn mower 1, the friction with the grass that occurs as the lawn mower 1 runs is slight and does not hinder the running of the lawn mower 1.
一方、芝刈機1の走行方向と略直交する仕切板
11の下端12は前記側部下端8よりも上方に位

2とハウジング2の側部下端8との距離Lの関係
をl≦Lとすれば、刈り取つた後の芝草が仕切板
11の下端12に触れることがないので、仕切板
11の下端12と芝草との間のフリクシヨンを完
全に無くすことができる。 On the other hand, since the lower end 12 of the partition plate 11, which is substantially perpendicular to the running direction of the lawn mower 1, is located above the side lower end 8, the lower end 12 of the partition plate 11 and the grass that are generated as the lawn mower 1 runs are separated from the lower end 12 of the partition plate 11. The friction between them is extremely small and does not increase the pushing load. Further, since the lower end 12 of the partition plate is bent so as to cover the rear end 6b of the blade 6 from below, foreign matter will not enter during the operation. In particular, the tip 6a of the blade 6 and the housing 2
and the lower end 8 of the partition plate 11 and the lower end 1 of the partition plate 11.
2 and the side lower end 8 of the housing 2 is l≦L, the grass after mowing will not touch the lower end 12 of the partition plate 11, so that the lower end 12 of the partition plate 11 and Friction between the grass and the grass can be completely eliminated.

動力で芝刈機を走行させることができる。 Although an example in which the housing structure of the present invention is applied to a lawn mower that is driven by hand has been described above, the present invention can also be applied to a lawn mower that is driven by the driving force of an engine. By doing so, the lawn mower can be run with less power.
