Description

[Detailed Description of the Invention] Industrial Application Field This invention relates mainly to the footrest of a small hydraulic excavator among construction machines.

Prior Art FIG. 4 is a side view of a small hydraulic excavator equipped with a conventional footrest 1. In the figure,
2 is a lower traveling body of a small hydraulic excavator, 3 is an upper revolving body, and 4 is a driver's seat 5 disposed on the upper revolving body 3 for a driver. FIG. 5 is a front view taken along line AA in FIG. 4. In the figure, 6 is a floor plate member of the upper revolving structure 3, 7 is a tread member of the footrest 1, and 8 is a stay member to which the tread member 7 is fixed. FIG. 6 is a perspective view of essential parts showing the vicinity of the footrest 1.

The footrest 1 is a floor plate member 6 in front of the driver's seat 4.
It is fixedly installed. The left and right feet of the driver 5 are allowed to come into contact with the tread member 7 of the footrest 1.

Problems to be solved by this invention Since a small hydraulic excavator is a working machine for performing light work, the width W of the machine body is very small as shown in FIG. The left and right footrests of the prior art are fixedly provided within the range of the vehicle width W. Therefore, when the driver is seated in the driver's seat and operates a small hydraulic excavator with his left and right feet on the footrests, it is difficult to operate the control lever group A (see Figure 5) located between the driver's crotches. Ta. As a result, the driver's driving operations became inconvenient, and he was unable to press his left and right feet firmly enough, leading to early fatigue.

This idea improves the above issues ergonomically,
To provide a footrest that allows a driver to press both his left and right feet and to operate a group of operating levers located between the driver's crotches in a comfortable posture.

Means for Solving the Problems The means of this invention taken to solve the above problems are as follows: (a) An additional tread member is provided rotatably via a hinge member on the outer edge of each of the fixed tread members of the left and right footrests. (b) When the additional tread member is not used, the additional tread member can be folded over the upper surface of the fixed tread member so that it can be stored, and (c) When the additional tread member is used, the additional tread member is placed outward of the fixed tread member. rotation reversal,
Further, the upper surfaces of both the tread members are configured to be able to be locked in a substantially flush state.

Function A: When the additional tread member is not in use, for example, when the small hydraulic excavator is stopped, the additional tread member can be folded over the top surface of the fixed tread member and stored in a retracted state. Therefore, in the above case, the footrest can be placed within the width of the vehicle.

(b) When using the additional tread member, invert the additional tread member outward from the fixed tread member with the axis of the hinge member as the center of rotation. Since the additional tread member protrudes in the left and right outer directions of the vehicle width, the driver can place his/her feet on the additional tread member by sufficiently widening his/her crotch.

Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings. FIG. 1 is a front view of a small hydraulic excavator showing an embodiment of the footrest 9 according to this invention. In the figure, the same reference numerals are given to the same components as in the prior art. 3'
10 is a fixed tread member of the footrest 9, and 11 is an additional tread member. FIG. 2 is a perspective view of essential parts showing the stored state of the footrest 9 of this invention. FIG. 3 is a perspective view of essential parts showing the state in which the footrest 9 of this invention is used. In the figure, 12 is a hinge member of the footrest 9.

Next, the structure of the footrest 9 according to this invention will be described with reference to FIGS. 1 to 3. An additional tread member 11 is rotatably provided at the outer edge of each fixed tread member 10 of the left and right footrests 9 via a hinge member 12. When the additional tread member 11 is not in use, the additional tread member 11 is folded over the upper surface of the fixed tread member 10 so that it can be stored; Additional tread member 11
The structure is configured such that the rotation can be reversed and the upper surfaces of both the tread members 10 and 11 can be locked in a substantially flush state. Note that in the footrest 9, the additional tread member 11 is rotatably provided with respect to the fixed tread member 10, but the additional tread member 11 may be provided so as to extend outwardly of the fixed tread member.

Next, the functions of the footrest 9 according to this invention will be described. When the additional tread member 11 of the footrest 9 is not in use, for example when a small hydraulic excavator is stopped, the additional tread member 11 is folded over the top surface of the fixed tread member 10 and stored as shown in FIG. Can be stored in any condition. Therefore, in the above case, etc., move the footrest 9 to the vehicle width W.
can be kept within the range of Further, when using the additional tread member 11, the additional tread member 11 is rotated about the axis of the hinge member 12 in the outer direction of the fixed tread end member 10 (in the direction of arrow B in FIGS. 1 and 3). Invert. The additional tread member 11 protrudes in the left-right outward direction of the vehicle width W, and its outer width dimension is the dimension W as shown in FIG.
The driver 5 can place his/her feet on the additional tread member 11 by sufficiently widening his/her crotch.

Effects of the invention In the footrest according to this invention, the additional tread member is rotatably provided with respect to the fixed tread member, and when the additional tread member is not in use, it is folded over the top surface of the fixed tread member and placed in a stored state. When the additional tread member is used, the additional tread member is rotated in the outward direction of the fixed tread member so that it protrudes beyond the vehicle width of the aircraft body. As a result, the driver can sit in the driver's seat, fully spread his crotches and press both his left and right feet, and can easily operate the group of operating levers located in his crotches in a comfortable posture.

Therefore, in the construction machine equipped with the footrest according to this invention, the driving posture of the driver, especially the posture of the driver's legs, is improved ergonomically, reducing driver fatigue, and at the same time improving driving comfort. Improve.
