DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, another embodiment of an armrest device for a construction machine according to the present invention will be described with reference to FIGS. 7 to 9. In order to avoid duplication of description, the same reference numerals are given to the same components as in the previous embodiment, and the same description is omitted.

Figure 7 is a cross-sectional view of another embodiment of the armrest device of the construction machine according to the present invention, a view corresponding to Figure 2 showing the previous embodiment. As shown in FIGS. 7 to 9, one end of the connection member 50 faces the operation panel 40, and the other end of the connection member 50 is rotatably installed with respect to the armrest 20. Armrest 20 is preferably rotatably installed in the left and right direction (LRD) or up and down direction (UDD) with respect to the armrest 20 as in the previous embodiment. A small diameter portion 56 having a reduced diameter is formed at an end portion of the connection member 50 facing the operation panel 40. This reduction in diameter is to form a step, the step surface by the step is directed to the operation panel 40 side. The first protrusion 59b is formed on the step surface facing the operation panel 40. It is preferable that a plurality of first protrusions 59b be formed, and in the case where the connecting member 50 has a cylindrical shape, the first protrusion 59b has a tooth-like shape arranged in a ring shape.

The slide block 58 is hollow, and the small diameter part 56 of the connection member 50 is slidably inserted in this hollow. That is, the slide block 58 is installed to be slidable with respect to the connecting member 50, but the movement range is limited by the first protrusion 59b in the direction of the armrest 20. A fourth nut 57 is coupled to an end of the operation panel 40 side of the connection member 50 in order to prevent the slide block 58 from being slid toward the operation panel 40 and separated from the connection member 50. On the other hand, a spring 58a is inserted between the fourth nut 57 and the slide block 58, and the spring 58a exerts an elastic force so that the fourth nut 57 and the slide block 58 are separated from each other. . That is, the spring 58a presses the slide block 58 to the armrest 20 side. The second projection 59a is formed at the end of the slide block 58 at the armrest 20 side. The second protrusion 59a is formed to be engaged with the first protrusion 59b of the connection member 50, and a plurality of second protrusions 59a may be formed similarly to the first protrusion 59b. If the first protrusion 59b is a sawtooth arranged in a ring shape, it is preferable that the second protrusion 59a is also a sawtooth arranged in a ring shape so as to conform to the first protrusion 59b.

The operation panel fixing bracket 42 is fixed to the slide block 58. The operation panel fixing bracket 42 is also fixed to the operation panel 40 by the fixing bolt 43.

When no external force is applied in such a configuration, as shown in FIG. 8, since the spring 58a pushes the slide block 58 toward the armrest 20 side, the first protrusion 59b and the second protrusion. (59a) is meshed. In this state, the operation panel 40 is suppressed from rotating about the connecting member 50 as the central axis.

However, as shown in FIG. 9, when the user pulls the operation panel 40 in the direction of the arrow, the slide block 58 moves to compress the spring 58a, and at the same time, the second protrusion engaged with the first protrusion 59b. 59a is separated from the first protrusion 59b. At this time, the user rotates the operation panel 40 as necessary with the connection member 50 as the central axis. Then, when the force pulling the operation panel 40 is removed, the second projection (59a) is the first projection while the slide block 58 is moved to the armrest 20 again by the restoring force of the compressed spring (58a). The rotation of the operation panel 40 is suppressed while engaging the 59b. Therefore, the rotation angle of the operation panel 40 can be adjusted according to the user's body shape by using the connection member 50 as a central axis through such an operation process.

If the previous embodiment is to enable the two-axis rotational movement of the operation panel 40 with respect to the armrest 20, the present embodiment is characterized in that it further enables one-axis rotational movement. In addition, in the present embodiment, the configuration for enabling additional axial rotational motion, that is, the first projection 59b, the second projection 59a, the spring 58a, the slide block 58, and the fourth nut 57 ) Is added to the configuration of the connection unit 90 of the previous embodiment, and consequently constitutes a part of the connection unit 90.

While the invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described.
