席の下方に設けてある乗用型作業車に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a riding vehicle such as a lawnmower, and more specifically, the present invention is directed to a method of reducing the load acting on the entire seat of the driver's seat through an elastic spring. The passenger seat is configured to be elastically supported with respect to a support base, and is provided with a detection switch located below the driver's seat for detecting downward displacement of the seating portion and determining the presence of the driver. Regarding work vehicles.

Conventional work vehicles are equipped with safety measures that prevent them from operating unattended;
For example, as disclosed in Japanese Utility Model Application Publication No. 60-131432, the case of the detection switch is bolted to a mounting plate fixed to the bottom surface of the seat (seating part),
A detection plate that is elastically supported by the mounting plate is installed above the operator that protrudes upward from the case, and when the detection plate is displaced downward due to the driver's load, the operator is displaced downward and detected. configured to operate;
The detection plate was configured to come into contact with the upper end of the mounting plate when the displacement reached the operating limit.

た。
In the conventional structure described above, when the weight of the driver is considerably large or when a sudden weight burden is applied, the detection plate comes into contact with the mounting plate to prevent excessive force from being applied to the detection switch. However, since the switch case is configured to come into contact with a mounting plate that is a rigid body, when the driver sits down, the shock caused by the contact between the rigid bodies is transmitted to the driver, making him feel like a foreign body. There was a risk that the sitting sensation would be worsened, and there was room for improvement.
本考案は上記不具合点を解消することを目的と
している。 The present invention aims to solve the above-mentioned problems.
本考案の特徴構成は、冒頭に記載した乗用型作

ある。
The characteristic configuration of the present invention is that, in the riding-type work vehicle described at the beginning, a support member for the detection switch is disposed on the seating portion side, and this support member is elastically supported so that it can be retracted downward with respect to the seating portion. There is a certain point.

異物感を感じることが無い。
Even if the operating force is applied to the detection piece of the detection switch beyond its operating limit when the driver is carrying a heavy load or a sudden load is applied, the support member that supports the detection switch will not touch the seating area. On the other hand, since it elastically retreats downward, there is no feeling of a foreign body due to contact between rigid bodies.
その結果、支持台に弾性スプリングを介して着

きた。
As a result, although the seating part is elastically supported by the support base via an elastic spring and has cushioning performance when seating, the problem is caused by contact between rigid bodies due to the detection operation of the switch that detects the seating state. This reduces the feeling of a foreign body, making it more comfortable to sit on.

う構成してある。 The traveling body 1 is provided with a safety measure such that the engine 8 is automatically stopped when a driver is not seated in the driver's seat 7. That is, a limit switch 10 is provided below the driver's seat 7 as a detection switch for detecting the downward deformation of the seating portion 9 made of a cushioning material and determining the presence of the driver. If the presence of a person is not determined, the engine 8 is configured to be stopped by a linkage mechanism (not shown). The lower front side of the driver's seat 7 is pivoted around the horizontal axis on the body side support stand 20, and the rear side is elastically supported via an elastic spring 21 for the load acting on the entire seat 9. It is structured like this.

ある。 The support member 15 is elastically supported by the driver's seat 7 so as to be retractable downward. To be more specific, headed bolts 17, 17, which are loosely inserted into the upper surface 16 of the outer peripheral part of the support member 15, are screwed onto the lower end part 11 of the seat, and coil springs 1 are attached to the bolts 17, 17.
8, 18 are fitted externally, and these coil springs 18, 18
are interposed between the bolt heads 19, 19 and the upper surface 16 of the support member 15, and the support member 1
5 is vertically movable and biased upward by coil springs 18, 18. When excessive weight is applied to the limit switch 10, the support member 15 is configured to be able to retreat downward against the biasing force of the coil springs 18, 18.
