[Prior art]

2. Description of the Related Art Conventionally, a cover that covers the upper surface of an operating member such as a switch provided on the fender of a work vehicle such as a tractor is already known from Japanese Utility Model Publication No. 58-42198.

[Problem that the invention attempts to solve]

However, when the cover is opened to operate an operating member such as a switch, the cover is not locked, and the cover support rattles due to the vibration of the aircraft, causing deformation and damage. There were also defects such as the cover being turned upside down when opened, and water pooling in the upside down cover during rain, which had to be removed each time.

The technical problem of this invention is to make it possible to lock the cover in the open position with a simple mechanism, but also to prevent rainwater from accumulating on the cover when it is open, and to prevent the cover from accumulating due to vibrations of the aircraft. To ensure that a support part is securely locked in an open position without being shaken or deformed or damaged.

[Means for solving problems]

The operation control unit cover locking device for a work vehicle according to the present invention, which was devised to solve the above problems, is as follows.

An operation panel for controlling the work equipment is provided on the side of the driver's seat, and a cover that covers an instruction operation member for automatic control on the operation panel is provided so as to be openable and closable, and the cover is attached to a handle member disposed near the operation panel. In a working vehicle in which a cover is configured to be detachable and can be fixed in an upright position, a convex portion is formed on the upper surface of the cover, and a support portion of the cover is arranged below a handle member to provide elastic support. The cover is attached to a member, and the convex portion of the cover is resiliently locked to the handle member from below.

[Function] During operation, the cover 12 is kept in a horizontal closed state to protect the instruction and operation member for automatic control.
2, the cover 12 can be easily held in an upright position by simply opening the cover 12 upward and pressing it toward the handle member 13.

Therefore, the instruction operating member can be operated smoothly and reliably while the cover 12 is stably held upright.

〔Example〕

An example of the present invention will be described based on the drawings.
Reference numeral 1 denotes a running body of an agricultural tractor having front wheels 2 and rear wheels 3, and a link mechanism 4 is provided at the rear of the running body 1 to support a working machine (not shown) so as to be able to move up and down. . 5a and 5b are rear wheels 3
The fender covers the upper surface, front surface, and inner surface of the vehicle, and the upper surface portion is formed substantially horizontally, and the front portion is sloped forward and downward. A seat 6 is provided in the center between the left and right fenders 5a and 5b. In addition, 7 is a bonnet that covers the engine part, 8 is a driving handle, and 9 is a step part.

Reference numeral 10 denotes an operation panel for controlling the working machine, which is provided along the outer shape of the fender 5b on the right side, and the horizontal part of the panel 10 has various instruction and operation members for automatic control, such as switches and volumes. S is provided, and the inclined portion of the operation panel 10 serves as a guide portion for the position control lever 11.

The instruction operation member S is configured to be operated by opening a cover 12 provided above it so as to be freely openable and closable.

The cover 12 is made of a transparent plastic material and has a convex portion 12a formed on the top surface so that the setting status of the instruction/operation member S can be seen.To explain the mounting structure in detail, 13 is formed in the shape of a gate when viewed from the side. This is a handle member having an elastic grip 13a made of hard rubber or the like on its upper side. Reference numeral 14 denotes a support member provided below the handle member 13 and having the outer end of the cover 12 hinged 15 at its central portion;
In some cases, as shown in FIG. 5, a notch 14a is provided in the hinged portion of the cover 12 to make the width narrower and provide elasticity so that the cover 12 is easily bent.

The front and rear bases of the handle member 13 and the support member 14
Bolts 16 are attached to the front and rear bases of the fender 5b along with the ends of the operation panel 10 on the outer side of the upper surface of the fender 5b.
It is screwed by 16.

Here, the cover 12 is urged in the closing direction by a rubber plate 15b provided on the back side of the hinge 15 portion, so that it does not rattle even when the body vibrates greatly. An elastic member such as a coil spring may be used instead of the rubber plate 15a.

The hinge 15 is provided so that its axis is located approximately directly below the grip 13a, and the cover 12
When the handle member 1 is opened upward against the elasticity of the rubber plate 15a, the convex portion 12a touches the handle member 1 as shown by the chain line in FIG.
The cover 12 is in elastic contact with the lower edge of the elastic grip 13a of No. 3, and the entire cover 12 is locked in an upright position that does not exceed the vertical direction.

Here, the support member 14 that supports the cover 12 is
If the entire grip is made of a thick member with a uniform width as shown in FIG. 6, the rigidity will be too high and the elastic grip 1
Only the elastic force of 3a can move the cover 12 to the handle member 13.
It may be difficult to make smooth ballistic locking on the
Furthermore, if the support member 14 is made of a thin member with a uniform width, it may deform at an early stage and may not be able to hold the cover 12 in an open state. If only this part is formed narrowly, the convex part 12 of the cover 12
Since the support member 14 also elastically deforms when the handle a comes into contact with the elastic grip 13a, the cover 12 is securely and elastically locked to the handle member 13.

The present invention is constructed in this way, and when carrying out agricultural work etc., the cover 1 is always kept on during operation.
2 is in a closed state to prevent rainwater from splashing on the instruction/operation member S for automatic control or from accidentally touching it by an operator, and the lower plane of the upper surface of the cover 12 is used as an elbow rest, and a convex The portion 12a can also be used as an elbow rest by serving as a non-slip portion for the elbow.

When the cover 12 is opened laterally to release the driver's seat side as required for driving, the cover 12 is opened upward against the closing direction bias of the rubber plate 15a and pushed toward the handle member 13. The convex portion 12a of the cover 12 comes into elastic contact with the lower portion of the grip 13a of the handle member 13, and is securely locked, so that it will not wobble or come off. Furthermore, since the cover 12 is held in an upright position that does not exceed the vertical direction, rainwater will not accumulate on the back surface of the cover 12 even in the event of rain.

Therefore, the opening/closing operation of the cover 12 and the adjustment operation of the instruction operation member S when opening the cover 12 can be easily performed with one hand.

[Effect of idea]

The present invention uses a handle member provided on the fender to lock the cover in the open position without providing a separate locking member, making the entire structure extremely simple. However, in order to prevent rainwater from accumulating on the back of the cover by keeping the cover open in an upright position that does not exceed the vertical direction, the cover is supported on an elastic support member, and a convex portion is provided on the top of the cover. When the cover is opened, the convex portion is elastically locked to the handle member, so the cover is securely locked without rattling due to vibrations of the aircraft, and this prevents deformation or damage of the cover support. is prevented. Further, the convex portion of the cover can be used to prevent the driver's elbows from slipping, and the upper surface of the cover can be used as an elbow rest, which has the advantage that the driver can work in a comfortable posture.

Furthermore, the cover member is located below near the handle member,
Even if other objects come into contact with the cover member unexpectedly, this can be prevented by the handle member, and the cover member can be prevented from being damaged.
