Description

Arm rest for construction machine

The present invention relates to an arm rest for a construction machine, and more particularly, a functional switch (for example, a traffic light, a light flashing switch, a buzzer, etc.) mounted to a console box is used as an arm rest of a seat. The present invention relates to an arm rest for a construction machine installed in an arm rest to secure a driver's visibility to a switch so that they can be conveniently operated.

As shown in Figure 1, a typical excavator,

The lower traveling body 1,

An upper swinging body 2 rotatably mounted on the lower traveling body 1,

Cab cap 3 and engine compartment 4 mounted on upper pivot 2,

A work device 11 consisting of a boom 5, an arm 6, and a bucket 7 rotatably mounted to the upper swinging body 2 and driven by the respective hydraulic cylinders 8, 9, 10 is provided. Include.

The general excavator cab cap shown in Figure 2,

Arm rests 13 and 14 rotatably mounted on the left and right sides of the sheet 12,

The console box is mounted to the cab cap 3 to one side of the sheet 12 and includes an operation lever (RCV lever) 15 for operating a work device such as a boom and a switch 16 such as an air conditioner operation switch. 17) and,

A console box mounted to the cab cap 3 on the other side of the sheet 12 and provided with an operation lever (RCV lever) 18 for operating a work device such as an arm and a switch 19 such as a light flashing switch ( 20) with,

And a travel pedal 21 and a travel lever 22 mounted to the cab cap 3 toward the front center of the sheet 12.

In this case, since the console boxes 17 and 20 are positioned under the arm rests 13 and 14, respectively, it is inconvenient to operate various functional switches 16 and 19 installed on the upper surfaces of the console boxes 17 and 20. You will take it. In other words, if the physical body is relatively small, such as a female driver, the arm does not touch, so in order to operate these switches (16, 19) to take the hassle of bending the body forward.

In addition, since the above-described functional switches 16 and 19 cover the driver's field of view due to the arm rests 13 and 14, in order to use the functional switches 16 and 19, the arm rests 13 and 14 are moved to the cab cap 3. After rotating to the rear side, the switches 16 and 19 are operated, which causes inconvenience.

An embodiment of the present invention relates to an arm rest for a construction machine, in which various functional switches mounted on a console box are mounted on an arm rest to maintain a constant distance between the switch and the driver so that the switch can be easily operated.

Embodiments of the present invention relate to an arm rest for a construction machine that ensures the visibility of a functional switch mounted to the arm rest to provide convenience to the driver.

Arm rest for construction machinery according to an embodiment of the present invention,

In the arm rest for construction machinery mounted to the left and right sides of the sheet provided on the cab cap rotatably,

Seating grooves formed on the upper surface of the arm rest,

A functional switch mounted on the seating groove,

It includes a switch cover which is coupled to the guide groove formed on the left and right seating groove slidingly openable.

Arm rest for a construction machine according to another embodiment of the present invention,

Seating grooves formed on the upper surface of the arm rest,

It includes a functional switch consisting of a membrane switch mounted to the seating groove.

Arm rest for a construction machine according to an embodiment of the present invention configured as described above has the following advantages.

By installing a light flashing switch on the arm rest to minimize the distance between the switch and the driver, reliability can be secured by easily operating the switch regardless of the driver's body type.

In addition, since the visibility of the functional switch mounted on the arm rest is secured, it is not necessary to operate the arm rest to operate the functional switch, thereby providing convenience to the driver.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are intended to explain in detail enough to enable those skilled in the art to easily carry out the invention, and thus It is not intended that the technical spirit and scope of the invention be limited.

Arm rest for a construction machine according to an embodiment of the present invention shown in Figures 3 and 4,

Seating grooves 23 formed on the upper surfaces of the arm rests 13 and 14, and

A functional switch (e.g., an air conditioner switch, a light flashing switch, etc.) 24 mounted to the seating recess 23, and

And a switch cover 26 coupled to the guide grooves 25 formed at the left and right sides of the seating recess 23 in a forward and rearward direction (referring to a driving direction of the equipment).

At this time, the cab cap configuration except for the functional switch 24 mounted on the seating grooves 23 formed in the arm rests 13 and 14 and the switch cover 26 coupled to the seating groove 23 so as to be openable and closed, Since the configuration is substantially the same as the configuration of the cab shown in Figure 2, the detailed description of their configuration and operation will be omitted, and the reference numerals for the overlapping configuration is the same.

Hereinafter, an example of the use of the arm rest for a construction machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4, when operating the functional switch 24 to use the air conditioner and the like provided in the construction machine, such as an excavator, the guide groove 25 formed on the left and right of the seating groove 23 Accordingly, after the switch cover 26 is opened by sliding movement toward the rear of the equipment, the functional switch 24 mounted in the seating groove 23 can be operated.

As the functional switches 24 are mounted on the upper surfaces of the arm rests 13 and 14, respectively, and the driver's visibility is secured, the functional switches 24 are rotatably mounted on the left and right sides of the sheet 12 to operate the functional switches 24. An operation for rotating the arm rests 13 and 14 to the rear of the cab 3 is unnecessary.

In addition, by minimizing the distance between the driver and the functional switches 24 mounted on the arm rests 13 and 14, the physical figure (e.g., arm length), such as a female driver, is relatively smaller than a man. Even in the case of the sheet 12, the functional switch 24 can be easily operated without bending the body forward.

On the other hand, although not shown in the drawings, the switch cover 26 is coupled to the mounting groove 23 formed in the above-described arm rest (13, 14) so as to open and close, the mounting groove 23 and the switch cover 26 Correspondingly, it can be mounted to be opened and closed by a hinge means (for example, a hinge) mounted by a corresponding arm and a pair.

Arm rest for a construction machine according to another embodiment of the present invention shown in Figure 5,

Seating grooves 23 formed on the upper surfaces of the arm rests 13 and 14, and

It comprises a functional switch 24 consisting of a membrane switch (membrane switch) mounted to the seating groove (23).

As a result, opening and closing of the switch cover 26 is unnecessary to operate the functional switch 24, and the operability of the functional switch 24 formed by the membrane switch is improved, thereby providing convenience to the driver.

At this time, since the membrane switch constituting the functional switch 24 is used in the art, a detailed description of the configuration and use examples thereof will be omitted.

According to the arm rest for a construction machine according to an embodiment of the present invention as described above, by mounting a light flashing switch on the arm rest to minimize the distance between the switch and the driver, regardless of the physical body of the driver Easy to operate Since the visibility of the functional switch mounted on the arm rest is secured, there is no effort to lift the arm rest to operate the functional switch, thereby providing convenience to the driver.
