Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation switch device in a cargo handling vehicle or the like.

[0002]

[Prior art]

 FIG. 4 shows a configuration of an operation switch device in a conventional cargo forklift, a walkie-type low lift, or other cargo handling vehicle. The operation switch device 10 switches the cargo handling tool up (UP) or down (DOWN) on the surface of the seat 5 made of polyester resin or elastic plastic, and switches the driving mode to power mode, economy mode, or the like. The operation unit 9 indicating the obtained operation instruction is printed.

5 (A) and 5 (B) are schematic cross-sectional views taken along the line BB of FIG. 4, in which a position corresponding to the lower surface of the operating portion 9 is guided by the substrate 6 to move vertically. A movable plate 7 that is movable is provided, and a switch 8 is fixed to the lower surface of the movable plate 7.

Therefore, as shown in FIG. 5B, when the operating portion 9 is pressed by the operator's finger, the operating portion 9 is elastically deformed and the switch 8 can be turned on and off. It is configured so as to be capable of driving a predetermined controlled object.

[0005]

[Problems to be solved by the device]

 By the way, the above-mentioned operation switch 10 has the advantage that it has no irregularities on the surface and gives a clean impression, and that the switch 8 can be turned on and off with an extremely slight operating force. On the other hand, it has the following drawbacks.

That is, since the surface portion of the operation switch device 10 is not provided with any concavo-convex portion, the operator who operates the operation switch device 10 must always visually confirm the operation portion 9 operated by himself / herself. I have to. Such a confirmation work is a great burden for an operator who has to carry out the work if he / she always has to visually check the distance, height, etc. from the load, cargo handling tools, shelves, etc. during the cargo handling work. It is lacking and not preferable for safety.

The present invention has been devised in view of the above-mentioned circumstances, and an object thereof is to identify an operation switch section that employs a seat switch without visually recognizing the operation switch section and to adopt a conventional seat switch. Another object of the present invention is to provide an operation switch device for a cargo handling vehicle or the like that can achieve the above-mentioned functions by slightly modifying the operation switch part.

[0008]

[Means for Solving the Problems]

 The present invention is an operation switch device having an operation part displayed on an elastic sheet, and a switch provided on the lower surface of the operation part, wherein the operation part is provided on the seat. It is based on a structure that is equipped with a guide plate having an operable opening.

[0009]

【Example】

 The first embodiment of the present invention will be described below with reference to FIGS. 1 and 2, and the same components as those of the conventional device will be designated by the same reference numerals.

As shown in the drawing, the operation switch device 1 according to the present invention exemplifies a case where a guide plate 2 is attached on a sheet on which a plurality of operation portions 4 are printed.

A circular opening 3 is formed in the guide plate 2 in this example so that the operation portion 4 printed and printed on the sheet 5 can be operated from above. FIG. 2 schematically shows a cross section taken along the line AA in FIG. 1, but as is apparent from this, when the operator's finger is groped on the guide plate 2, the operator's finger is guided to the guide plate 2 and the operating portion is operated. You can search for 4.

Even when there are a plurality of operation units 4 as in this example, the operator can usually remember which position the operation unit 4 is and which operation system, while repeating the work. Therefore, when the entire palm is touched so as to cover the operation switch device 1, the respective operation parts 4 can be recognized by the respective opening parts 3, and further, the arbitrary operation part 4 can be operated by the memory. .

Next, a second embodiment of the present invention will be described with reference to FIG. In this example, the openings 3A corresponding to the operation unit 4 on which the letters “UP” indicating the ascending of the cargo handling implement and the operation unit 4 on which the letters “DOWN” indicating the descending are displayed are respectively formed. The operation unit 4 having a substantially triangular shape and having "UP" is processed so that the apex angle is upward, and the operation unit 4 having "DOWN" is processed so that the apex angle is downward. The following are examples.

That is, by making the shape of the opening 3A to be a shape that can be thought of as an operation idea performed by the operation of the operation unit 4, the "UP" is given by the tactile sensation of the finger when touching the opening 3A. And, it becomes easy to find an arbitrary operation unit 4 of “DOWN”.

Although described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. In the second embodiment, “UP” , Only "DOWN" has been illustrated, but it goes without saying that the operation unit 4 other than this can also be adopted. Specifically, it may be possible to make a shape similar to a wrapper in “HORN” that emits a warning sound, a large circle in the “POWER” mode, and a small circle in the “ECONO” (energy saving mode). .

[0016]

[Effect of device]

 As a result of adopting the above-described configuration, the present invention can identify the operation switch section using the seat switch by the tactile sensation of the operator's finger without visually observing the operation switch section. This can be achieved by a very slight modification in which only the guide plate 2 is attached to the switch part.

In addition, in the second embodiment, the shape of the opening is formed so as to evoke an idea of operation performed by the operation of the operation unit, so that the tactile sensation of a finger when touching the opening is provided. Thus, it becomes easier to find an arbitrary operation unit. Furthermore, the function of the seat switch, which can be turned on and off by a slight operation force, is not impaired.
