る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a rotary cover structure for a power tiller, and more specifically, the present invention relates to a rotary cover structure for a tiller. Improvement of the rotary cover structure of a power tiller, in which left and right covers are provided that can be freely opened and closed in a fixed rocking position, and side covers are provided on the outer ends of these covers, respectively, so that the swinging position can be fixed and rocked around the axis in the longitudinal direction of the machine. Regarding.
従来は、上記した左右開閉カバー及びサイドカ
バーの揺動及び揺動位置固定の構造としては、例
えば、実開昭55−126702号に開示されている如
く、サイドカバーの揺動及び揺動固定構造が、開
閉カバーのそれと独立して設けられていた。
Conventionally, as a structure for swinging and fixing the swinging position of the above-mentioned left and right opening/closing cover and side cover, for example, a structure for swinging and fixing the swinging position of the side cover is disclosed in Japanese Utility Model Application Publication No. 55-126702. However, it was provided independently from that of the opening/closing cover.
こうした従来の構造を簡略化すべく、サイドカ
バーの揺動及び揺動固定の構造と開閉カバーのそ
れとを部材を兼用することを考えた。
In order to simplify this conventional structure, we considered using a member for both the rocking and rocking fixing structure of the side cover and that of the opening/closing cover.
即ち、前記ロータリフレームの前記開閉カバー
よりも上方位置に、機体前後方向軸芯をもつ一本
の固定ピンを設け、前記開閉カバーの上面にブラ

前記長孔を前記固定ピンに摺動自在に嵌入すると
ともに、他端を前記連結ボルトに回動自在に連結
して設け、且つ一端側に長孔を有するサイドカバ
ーアームを、前記長孔を前記連結ボルトに摺動及
び固定自在に連結し、それらの他端を前記サイド
カバーに枢着したのである。 That is, a fixing pin having an axis in the longitudinal direction of the machine body is provided at a position above the opening/closing cover of the rotary frame, and brackets are fixed to the upper surface of the opening/closing cover. A connecting bolt and a nut are provided respectively, and an opening/closing cover arm having a long hole at one end is provided.
A side cover arm is provided in which the elongated hole is slidably fitted into the fixing pin, and the other end is rotatably connected to the connecting bolt, and the elongated hole is connected to the elongated hole. They were slidably and fixedly connected to the connecting bolts, and their other ends were pivotally connected to the side cover.
こうすることによつて、前記ブラケツト及び連
結ボルトは、開閉カバーアームの一端とサイドカ
バーアームの一端とを枢支及び摺動固定自在に連
結するのに兼用できる。 By doing so, the bracket and the connecting bolt can be used to connect one end of the opening/closing cover arm and one end of the side cover arm in a pivotable and slidable manner.
しかし乍ら、上記改良構造では、前記連結ボル

イドカバーアームの摺動とが共に固定されるの
で、開閉カバーのみを上方に揺動させようとして
開閉カバーアームの回動固定を解除しようとすれ
ば、サイドカバーの摺動も自由となり、両カバー
の揺動角度を各々所望の角度に調節するのは面倒
である。 However, in the improved structure described above, when the connecting bolt is tightened, both the rotation of the opening/closing cover arm and the sliding movement of the side cover arm are fixed, so it is difficult to open/close when attempting to swing only the opening/closing cover upward. If an attempt is made to release the fixation of rotation of the cover arm, the side cover will also be free to slide, making it troublesome to adjust the swing angles of both covers to desired angles.
そこで、こうした問題を解決する方法として、
第５図に示す如く、前記連結ボルト１３′を段付
きに構成し、以つて連結ボルトの締付けによつて
も、開閉カバーアームの回動は許し乍らサイドカ
バーアームの摺動のみを固定することが考えられ
た。 Therefore, as a way to solve these problems,
As shown in FIG. 5, the connecting bolt 13' is structured in a stepped manner, so that even when the connecting bolt is tightened, only the sliding movement of the side cover arm is fixed while allowing the opening/closing cover arm to rotate. I thought about that.
しかし、このような段付ボルト１３′は削り出
し加工が必要でコスト高になるという欠点があ
る。 However, such a stepped bolt 13' requires machining, resulting in high cost.

摺動のみが固定されるように構成したのである。
In order to solve the above-mentioned problems, the present invention uses a dual-purpose structure in which the above-mentioned bracket and connecting bolt can be freely rotated and slidably fixed to the opening/closing cover and the side cover, and the connecting bolt of the opening/closing cover arm is fixed to the opening/closing cover arm. A collar having a width longer than the wall thickness of the opening/closing cover arm is provided in the insertion hole so as to be relatively rotatable, and only sliding of the side cover arm relative to the connecting bolt is fixed by tightening the connecting bolt and nut. It was configured like this.
前記連結ボルトとナツトとを締付ければ、開閉
カバーのボルト挿入孔に遊転自在に介装されたカ

締弛緩によつて、開閉カバーの揺動に係わりなく
行うことができる。
When the connecting bolt and nut are tightened, the collar, which is freely rotatably inserted into the bolt insertion hole of the opening/closing cover, has a width longer than the wall thickness of the opening/closing cover arm. Only the side cover arm is pressed against the bracket and fixed without any pressure. As a result, the swinging of the side cover is fixed, but the rotation of the opening/closing cover arm is always free, so the opening/closing cover can be rocked without releasing the locking of the side cover. can. In addition, the side cover can be fixed by tightening and loosening the connecting bolts and nuts, regardless of the swinging movement of the opening/closing cover.

Therefore, the bracket for swinging and fixing the opening/closing cover and the side cover can also be used as the connecting bolt and nut, reducing the number of parts, and it can be obtained by cutting a commercially available pipe to size. By simply using the collar, the angles of the opening/closing cover and the side cover can be adjusted without interference with each other, which has the advantage of being inexpensive.
