[Problems to be solved by the device]

 In the conventional remote control transmitter 1, since the cover 5 is located at the position indicated by the imaginary line in FIG. 4 in use, there is a problem in that the control surface 3 cannot be prevented from being soiled by paint and other scattered objects. there were.

In addition, since the cover 5 is in the position of the imaginary line in FIG. 4 in the use state, the center of gravity of the remote control transmitter 1 moves in a direction away from the operator, resulting in poor weight balance and good usability. There was also the problem of not having it.

An object of the present invention is to provide a new remote control device that solves the problems of the above remote control transmitter.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the remote control device for a work vehicle of the present invention is a remote control device for a work vehicle in which an operating machine is mounted on the vehicle and the vehicle or the work machine is operated by a handheld remote control transmitter. In a remote control transmitter having a cover for covering the control surface on which the operation switches and the like of the remote control transmitter are arranged, the cover is made of a planar elastic body, and one end of the cover is placed at an appropriate position of the remote control transmitter. It was configured by attaching to the.

[0010]

[Action]

 In the remote control device for a working vehicle of the present invention configured as described above, since the cover for covering the control surface on which the operation switches of the remote control transmitter are arranged is made of a planar elastic body, the cover does not change when the control surface is used. As it is located on the upper part, the control surface and operation switch etc. do not get dirty.

[0011]

【Example】

 A remote control device for a working vehicle according to the present invention will be described with reference to FIGS. Reference numerals 2 to 4 shown and described in FIG. 4 as a conventional technique have the same meanings in the following description, and therefore the description thereof is omitted and the same reference numerals are used.

Reference numeral 11 is a remote control transmitter, 12 is a cover, and 13 is a double-sided tape (a sticking means within the scope of the utility model registration claim). The remote control transmitter 11 has a switch 4 and a pilot lamp (not shown) arranged on the control surface 3 of the case 2, and in order to prevent damage and dirt on the switch 4, the pilot lamp and the control surface 3, the control surface 3 A cover 12 is provided to cover the. The cover 12 is made of a planar elastic body (for example, transparent vinyl), and when one end of the cover 12 normally holds the remote control transmitter 11 in a use state, the remote control transmitter 11 has a It is affixed with double-sided tape 13 in place on the side far from the operator. The periphery of the cover 12 is in contact with the case 2.

When using the remote control transmitter 11, the remote control transmitter 11 is taken out from the storage place in the proper place, the other end of the cover 12 is turned over, and the finger is operated between the cover 12 and the case 2 on the vertical surface 3. Insert it up and operate the switch 4. This will drive the vehicle or work implement. When you are done, remove your fingers from between the cover 12 and the case 2 and store the remote control transmitter 11 in place.

Even when used in this way, the cover 12 is made of a planar elastic body, and therefore the cover 12 is located above the control surface 3, so that the control surface 3, the operation switch 4, etc. Not only does it not get dirty, but the movement of the center of gravity of the remote control transmitter 11 hardly occurs, so it is very easy to use.

When the cover 12 is transparent and the pilot lamp is monitored or the position of the operation switch 4 is checked, when the cover 12 is dirty, the cover 12 attached with the double-sided tape 13 is easy. It can be removed and replaced with a new cover 12 easily. Therefore, when the pilot lamp is monitored or the position of the operation switch 4 is checked, there is no problem that the cover 12 cannot be checked due to dirt.

Further, since the hinge 6 and the lock 7 which are conventionally used are not required, the number of parts is reduced and the operation is simple because there is no unlocking and locking operation of the lock 7.

The cover 12 may be a flat plate as shown in FIG. 1 or a three-dimensionally shaped one as shown in FIG. 3, and the attaching means 13 may be a double-sided tape or a magic fastener. . In the present embodiment, the attachment location is on the side of the control surface 3 of the case 2, but the cover 12 may be foldable and may be on another surface.

By the way, when the wired remote control transmitter 22 is adopted in the aerial work vehicle 20 as shown in FIG. 5 to FIG. 6, the conventional remote control transmitter 22 is located near the intersection of the sides of the platform 21 in a plan view. A fixed point 24 of the cable 23 is provided so that the remote controller transmitter 22 can be used on the platform 21. When moving and using the remote control transmitter 22 on the platform 21 according to the work location, in order to support all work locations, the length of the remote control cable 23 should be at least the plane view of the platform 21. The diagonal length (r) is required.

However, if the fixed point 24 of the remote control cable 23 is set to the fixed point 25 located at the midpoint of the long side of the platform 21, the length of the remote control cable 23 is longer than the conventionally required length (r). A short length (R) is sufficient. In particular, the greater the difference between the long side and the short side of the platform 21 in plan view, the greater the difference between the length (r) and the length (R), and the greater the saving effect of the remote control cable 23, the more the surplus. The risk of getting caught in the remote control cable 23 is reduced and safety is improved.

Further, when the remote control transmitters 1, 11, 22 are not used, such as when transporting a work vehicle, a hangar 30 for storing these remote control transmitters 1, 11, 22 is installed on the floor surface of the platform 21. If it is provided at the bottom of the, it is convenient for storing and taking out.
