Description

The present invention relates to a hand-held mower.

As a conventional hand-held mower, the thing of the following patent document 1 is known. This mower has a main body frame for holding an engine, a pair of left and right wheels provided at the lower end of the frame, and a cutting blade provided in front of the wheels and rotated by the engine. When using this mower, the operator holds the handle and lifts the mowing blade to a certain height, advances it by hand, and swings the mowing blade to the left and right by operating the handle to mow. .

JP 2003-265013 A

However, this mower has a problem that the operability is poor because the handle with low rigidity is swung left and right to swing the main body frame and the cutting blade left and right. In addition, the vibration of the engine and the vibration of the cutting blade are directly transmitted to the hand through the handle having low rigidity, which may cause white wax disease.
An object of the present invention is to provide a hand-held mower that solves these problems.

A hand-held mower according to the present invention includes a main body frame for holding an engine, a pair of left and right wheels provided at a lower end of the main body frame, a handle connected to the main body frame, and a pair of left and right wheels. A push-type grass mower provided in front and provided with a cutting blade that is rotated by the engine, and in particular, the main body frame is obtained by bending a U-shaped frame in a plan view into an L-shape in a side view. Both ends of the gate-type handle are connected to both open ends of the frame, and the engine and the cutting blade connected to the engine are attached to the main body frame through vibration-proof rubber. It is characterized by.

Moreover, the open both ends of the main body frame and the both ends of the portal handle are connected via an angle adjusting mechanism.

According to the present invention, both ends of the gate-type handle are connected to the open ends of the main body frame obtained by bending a U-shaped frame in plan view into an L-shape in side view. The rigidity of the steering wheel can be increased, and the operability and stable running performance of the steering wheel can be improved. In addition, the engine that is the vibration source and the cutting blade connected to it are attached to the main body frame via anti-vibration rubber, which reduces the vibration transmitted to the hand via the handle, thereby reducing white wax disease etc. Can be made.

The side view of the hand-held type mower according to the present invention. The top view of the said hand-held type mower. The side view (I) and A arrow view (B) of an angle adjustment mechanism. The side view (I) and A arrow view (B) of the attachment part of vibration-proof rubber

Hereinafter, embodiments of a hand-held mower according to the present invention will be described with reference to the drawings.

1 and 2, a hand-held mower according to the present invention includes a main body frame 2 that holds an engine 1, wheels 7 provided at the lower end of the main body frame 2, and both open ends of the main body frame 2. And a cutting blade 3 that is provided in front of a pair of left and right wheels 7 and that is rotated by the engine 1. The cutting blade 3 is made of a string-shaped plastic blade or a disk-shaped metal tooth.

The main body frame 2 is obtained by bending a pipe frame into a U shape in a plan view and further bending it into an L shape in a side view. A pair of left and right wheels 7 is attached to the lower end bent into the L shape via a gate-shaped frame. In addition, both ends of the gate-type handle 4 are connected to both open ends of the main body frame 2 via an angle adjusting mechanism 6. A rubber grip 10 for preventing vibration is applied to the grip portion of the portal handle 4.

  Further, as shown in FIG. 4, reinforcing plates 11 are attached to the rising portions of the L-shaped side view divided on both sides of the main body frame 2 through four anti-vibration rubbers 5 at the top, bottom, left, and right. An engine 1, a cutting blade 3, and a power transmission mechanism that couples them to transmit the rotation of the engine 1 to the cutting blade 3 are attached to a base portion 12 of the plate 11 via four stems 13. . The reinforcing plate 11 is formed by fixing a triangular metal plate to the opposite side of the metal rectangular base portion 12 so that the entire reinforcing plate 11 is a quadrangular pyramid. The below-mentioned holding rod 9 is supported.

The power transmission mechanism includes a clutch case 8, a cylindrical holding rod 9 whose base end is coupled to the clutch case 8, and whose front end projects obliquely downward and forward, and a mounting plate provided at the distal end of the holding rod 9. The drive shaft is rotatably provided inside the holding rod 9, and one end of the drive shaft is connected to the clutch, and the other end is connected to a rotary shaft that rotates the cutting blade 3. Although this rotating shaft is built in the mounting board, since these are well-known structures, those detailed description is abbreviate | omitted here.

  As shown in FIG. 3, the angle adjusting mechanism 6 is constituted by a tooth-type clutch in which two toothed disks are engaged with each other. Then, when the engagement of the toothed clutch is released by loosening the knob nut on the side, the handle 4 can swing up and down as shown by the phantom line in FIG. 1, and the handle 4 is adjusted to a desired inclination angle. Then, if the knob type nut is tightened, the handle 4 is fixed at that angle. Thereby, it can be made to respond | correspond to the height of the operator who uses a mower.
