Abstract

PURPOSE:To improve operating efficiency and stability and further safety by locating a gripping part between a head part and a power source part which are heavy materials and providing the under side of the grip with a guard part. CONSTITUTION:When a current is passed through a motor 10 by operating a switch handle 31 while gripping a gripping part 3 and simultaneously pressing a lock button 32 in a lawn mower, a rotating blade 11 is rotated and driven with the motor 10. Lawn entering a space between combs into the shape of comb teeth in the upper cover 5 and the lower cover 6 is cut with the rotating blade 11. At this time, the gripping part 3 is located between a head part 1 containing a blade driving means such as the motor 10 which is a heavy material and a power source part 2 which is similary a heavy material. Thereby, the center of gravity is near the gripping part 3 and lawn grass cutting operation can be performed in a stabilized state. Since a guard part 4 located below the gripping part 3 with a space therebetween prevents hands gripping the gripping part 3 from contacting cut lawn grass, stones, etc., the operation is safely carried out without cutting the hands with the cut lawn grass, etc.

Description

[Detailed description of the invention]

(Industrial Field of Application) The present invention relates to a lawn mower, particularly a small-curve J2 mower for home use.

[Conventional technology]

There are small lawn mowers that can be used with one hand and are powered by batteries. This is lower rf+j lul
The shape i7 is made up of a heel part 1, in which a blade is arranged on the l, and a blade driving means such as a motor is built into the upper part, and a grip part that is connected at one end to the upper part of the hep 1 part.
-, the battery is built into the grip.

[Invention or problem to be solved]

In this case, since the center of gravity is located at the center of gravity of a part of the blade that has a built-in blade drive means such as a motor, which is a heavy object, it has poor operability and lacks stability. There is a problem in that the gripping hand may be damaged by grass clippings or the like. The present invention has been made in view of these points, and its purpose is to provide a lawn mower that has good operability, stability, and safety.

[Means to solve the problem]

Accordingly, the present invention provides a grip section that extends between the head section in which the blade is disposed on the lower surface and the blade driving means such as a motor is built in the upper part, and the power supply section equipped with the battery. A feature of the present invention is that a car section 1, which is located below the chrysophyte section, is distributed between the two lower portions with a space interposed therebetween. [Function] According to the present invention, since the grip portion is located between the head portion, which is a heavy object, and the power source portion, the center of gravity is located near the grip portion, which improves stability and operability. ,
Also, the presence of the card section makes it highly secure. ``Embodiment'' The present invention will be described in detail below based on the illustrated embodiment. This lawn mower is composed of a head section 1, a power supply section 2, a grip section 3, and a force section 1/section 4. As shown in Fig. 2, the head section has a built-in motor inside its upper part and a rotary blade installed on the bottom side, and is attached to the output shaft of the motor. The rotation of the motor 10 is transmitted to the rotary blade 11 by meshing the wheel 14 fixed to the J shaft 13 of the LI!1 turning blade 11.Installation To install the rotary blade 11 on the shaft 13/\, presser plates 1 to 16 fixed to the mounting shaft 13 with screws 17 press the rotary blade 1 against the sleeve 15 that covers the mounting shaft 13. This is done by 3.Therefore, on the upper side of the circumference of the rotary blade 11, there is an upper power hardener 5.
In the lower direction, a torque carrier 6 is provided. In the figure, 60 is attached to the lower cover. The upper side surface and the lower surface 111 of this part 1 to part 1 are provided with one end of the cleaner part 3 and each of the car parts 1 and 4. Furthermore, a sliding switch handle 3■ and a lock button 32 are arranged, and a switch body 33 is arranged inside the clip part 3. Furthermore, a flaker 40 is disposed inside the other end of the guard portion 4 . The power supply section 2 is configured as a rechargeable battery pack, and is connected to the grip section 3 and the other end of the card section 4. In addition, head 1, part 1, grip part 3 and force -
1 part 4 of the outer shell {1, integrally formed by the housing 7 divided into two parts. In the lawn mower formed as described above, the motor 10 is energized by gripping the grip part 3 and operating the switch handle 1/ru 3l while pressing the lock KJ32. The rotary knife 11 is driven to rotate, and the grass that is inserted between the comb teeth of the upper cover 5 and the lower cover 6, which are formed in a comb shape, is cut by the rotary knife 11. At this time, the head section which houses the blade drive means such as the motor 10, which is heavy, is also heavy! A grip part 3 is installed between the power supply part 2, which is an L object, and the center of gravity is therefore near the grip part 3, allowing mowing work to be carried out in a stable state. The card portion 4, which is formed wider than the grip portion 3 and is located with a space below the grip portion 3, is designed to prevent grass clippings, stones, etc. from coming into contact with the hand holding the grip portion 3. You won't end up cutting your hand because of it. In addition, since it is built in the grip part 3 or is related to a switch, we have taken into account the ease of pressing and holding, as shown in Fig. 3 and Fig. 71. In addition, the grip part 3 has a narrow finish. Even if it is made thin in this way, since the card portion 4 acts as reinforcement, there will be no strength problem. FIG. 5 and subsequent figures show an example in which a lawn debris scattering prevention cover 8 is detachably attached to the head portion 1. The anti-scattering cover 8 arranged along the outer peripheral surface of the head part 1 is fixed by a screw 82 that is inserted through a protrusion 81 at the center of the inner peripheral side and pushed into the head part 1, This prevents grass debris cut by the rotation of the machine from scattering toward the worker's hands, fingers, and face.

【Effect of the invention】

As described above, in the present invention, firstly, a grip section is provided between the head section which incorporates a blade driving means such as a motor, which is a heavy object, and the battery power supply section, which is also a heavy object.
Since the center of gravity is located near the grip, mowing work can be done in a stable and easy-to-operate manner.Also, since there is a cart section below the grip, the hand holding the grip does not have to move the mowing lawn. It is highly safe because it does not come into contact with rocks or stones, and there is no risk of injury to your hands. Furthermore, the head section and power supply section are connected not only to the grip section but also to the gar 1 section. Even if the grip part is made thin with emphasis on ease of grip, it will not cause problems in strength, and therefore the grip part will be easy to grip and workability will be high. can be easily performed.
