Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch operating member of an electric mower such as a lawn mower.

[Prior art]

In the electric cutting machine, as shown in FIG. 8, a general-purpose switch 4 is provided near the grip 3 of the handle 2.
However, this is extremely dangerous because if it is switched to the ON side, it cannot be stopped immediately when a danger occurs suddenly because it keeps the ON state even if no operating force is applied. . For this purpose, only when the lever 5 is tilted sideways as shown in FIG. 9 or as shown in FIG.
The switch 4 is turned on only when the user pulls the switch 4 toward the end of the grip 3. When the hand is released from the lever 5, the lever 5 is returned by the bias of the spring and the switch 4 is turned off, so that the mowing machine can be stopped quickly.

[Problems to be solved by the invention]

However, in these cases, the hand that operates the switch is always limited to one hand, and the position where the grip is held is also limited, so that, for example, the power cord is not trapped. It is very difficult to operate the switch while handling the power cord with an empty hand and press the reaper to mow the lawn. The present invention has been made in view of such a point, and an object of the present invention is to provide a switch operating member of an electric reaper that is safe and has excellent usability.

[Means for Solving the Problems]

Thus, the present invention provides that the grip provided at the upper end of the handle of the reaper is composed of a pair of side pieces and a grip part connecting between the two side pieces, and is substantially parallel to the grip part, and A substantially U-shaped lever having substantially equal lengths and side pieces extending from both ends thereof is disposed close to the grip portion, and both side pieces of the lever are slidable on both side pieces of the grip. The switch is supported and the switch is opened and closed by the slide of the lever which is slidable in a direction orthogonal to the longitudinal direction of the grip portion, and the lever is urged by a spring member in a direction in which the switch is turned off. It is characterized by having [Operation] According to the present invention, since the lever has a length substantially equal to the entire width of the grip portion, the lever can be operated and the switch can be turned on regardless of where the grip portion is held, Also, if you release your hand from the lever, the lever will return by the spring and the switch will be turned off, and since both sides of the lever are slidably supported by both sides of the grip, The lever slides smoothly even if a lever having a length substantially equal to the entire width is operated. [Embodiment] Hereinafter, the present invention will be described in detail based on the illustrated embodiment. As shown in FIG. 1, the electric reaper has a reaper (not shown) disposed on a lower surface side. Body housing with wheels 11 and rollers 12 attached
Body 1 with grass basket 13 detachable on the back side of 10
And a handle 2 having one end connected to the main body 1. The handle 2 here is formed of a U-shaped base portion 20 and a pair of extension portions 21, 21 each having one end connected to both upper end portions of the base portion 20.
The upper ends of the 21 are connected to each other by a grip 3 formed in a rectangular frame shape. As shown in FIG. 2, the grip 3, to which a pair of side pieces 32, 32 is fixed at the upper end of the extension parts 21, 21, is attached to the grips 32,
32 and a grip portion 30 and a connecting piece 31 connecting the upper end and the lower end of the extension portions 21 and 21 are formed in a rectangular frame shape. The switch 4 and the breaker 6 are arranged inside the connecting piece 31 from which the feed wiring 16 to the main body 1 is drawn out. The lock handle 7 is slidably attached to the grip portion 30. The lever 5 for turning on and off the switch 4 disposed in the connecting piece 31 is disposed near the grip 30 in the space between the grip 30 and the connecting piece 31 in the grip 3, and the grip 30 is provided. It is formed as a U-shape which extends from the both ends to the side pieces 52, 52, respectively.
Are slidably accommodated in the respective side pieces 32, 32, and guide portions 54, 54 provided at the tips of the respective side pieces 52, 52,
The slide guide is received by a plurality of waterproof ribs 33 formed in the grip 3, and the lever 5 is urged away from the grip portion 30 by the return springs 56, 56. A projection 55 attached to one of the guides 54 faces the push button of the switch 4. The lock handle 7 arranged in the grip portion 30
Is always in a position pushed in one direction by the bias of the spring 72. At this time, as shown in FIG. 2, a pair of projections 50, 50 projecting from the center of the lever 5 In order to abut on the protrusion 70 in the above, even if the user tries to pull the lever 5 toward the grip part 30 with the hand gripping the grip part 30,
This is prevented, so that the push button of the switch 4 is turned off by being pushed by the projection 55. When the lock handle 7 is slid against the spring 72, the projection 50 is opposed to the recess 71 formed in the lock handle 7 at this time, and the lever 5 can be pulled toward the grip 30 side. Becomes When the lever 5 is pulled, as shown in FIG. 3, the projection 55 comes off from the push button of the switch 4, so that the switch 4 is turned on and the mowing device in the main body 1 is operated. When the hand is released from the lever 5, the lever 5 is returned by the bias of the pair of return springs 56, 56, and the switch 4 is turned off. In the middle of both side pieces 52, 52 of the lever 5, a thin neck part 5 is provided.
3 and 53 are formed, and the elasticity of the spring is hardly applied to the tip of the side piece 52. Therefore, when the lever 5 and the side pieces 52, 52 are integrally formed, the two side pieces 52, 52 are formed. It is possible to prevent a situation in which a smooth sliding operation of the lever 5 such as an inward fall or an outward open due to distortion after molding is hindered, and the lever 5 can be operated with the grip portion 30 being held. However, since the lever 5 performs a smooth sliding operation, and is returned by the pair of return springs 56, the return operation is also performed smoothly. On both sides 32, 32 of the grip 3, there must be a slit through which the lever 5 passes. Rain water may enter the grip 3 through this slit.
The rainwater is guided to the drain hole 34 side by the waterproof rib 33, and does not enter the connection piece 31 in which the switch 4 and the breaker 6 are arranged. The small hemispherical projection 51 formed on the tip end surface of the projection 50 of the lever 5 can slide between the projection 50 and the lock handle 7 even when the operation of sliding the lock handle 7 while pulling the lever 5 is performed. The dynamic resistance is reduced so that the unlocking operation of the lock handle 7 can be performed smoothly. The return push button 60 of the breaker 6 projects from the surface of the connecting piece 31 on the grip portion 30 side in a state covered with the waterproof rubber 61. 4 and 5 show another embodiment. Here, the lever 5 bends a metal bar into a C shape,
A guide plate 57 is fixed to both ends, and the lock handle 7 is arranged on the connecting piece 31 side. Connecting piece 31
The lock handle 7 slidably attached to the
A pair of lock levers 72, 72 projecting to both sides are provided.
And the lever 5 is locked. in this case,
Since the locking of the lever 5 is performed in two places, the locking becomes more secure. When the lock handle 7 is slid, the lock levers 72, 72 are opposed to the grooves 58, 58 formed in the guide plates 57, 57, so that the lever 5 can be operated. Further, when the lock handle 7 is provided on the connecting piece 31 side in this way, the unlock operation and the operation of the lever 5 cannot be performed simultaneously with one hand, so that the safety is also high in this respect. . The breaker 6 in this embodiment is attached to the center of the lock handle 7 to improve visibility,
The operability of the breaker 6 is improved. By the way, when the lever 5 is formed by bending a metal rod as described above, the diameter of the lever 5 cannot be increased so much. The grip is deteriorated when the grip 5 is pulled, but this is achieved by forming the eaves 38 that cover the lever 5 when the grip 5 is pulled toward the grip 30, as shown in FIG. Can be improved. In addition, as shown in FIG. 7, the improvement can be achieved by mounting a large-diameter hollow curler 59 on the lever 5. In particular, if the curler 59 is freely rotatable with respect to the lever 5, the curl 59 is rotated in accordance with the movement of the finger as the lever 5 is pulled, so that the operational feeling is improved.

【The invention's effect】

As described above, in the present invention, since the lever has a length substantially equal to the entire width of the grip portion, the switch can be turned on by operating the lever regardless of where the grip portion is held. In order to turn the switch on and off by sliding a long lever that is almost the same length as the entire width of the grip, the lever slides smoothly even if you operate the wide lever. There is, for this reason, it is possible to operate the lever and turn on the switch reliably regardless of where the grip is gripped, and the usability is good because the position where the grip is gripped is not limited, and When the hand is released from the lever, the lever is returned by the spring bias and the switch is turned off, so that the lever can be used safely.
