Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure for supporting a driver seat of a forklift.

(Prior Art) Conventionally, as shown in FIG.
The driver seat 4B is attached to the engine hood 3, which covers the engine in the center of the vehicle body, so that the front and rear positions can be finely adjusted. However, in a small forklift truck, the front field of view may be greatly obstructed by the load when loaded. In order to solve this problem, the driver's seat and driving device may be placed at a position about 400 mm higher than a normal forklift to ensure a forward field of view when loaded, in which case Supported the driver seat 4A by the device disclosed in JP-A-61-282296 (see FIG. 10). That is, a supporting member 6 which can be horizontally swung is pivotally supported on one side of the head guard pillar 2, and the supporting member 6 is detachably locked to the other head guard pillar 2 so that the driver seat 4A This is a device in which the seat stand 4S to be attached is supported by the support member 6.

(Problems to be solved by the invention) However, in the driver seat having the above-described configuration, in order to open the engine hood, the pin holding the support member is removed on one side of the vehicle body, and then the support member is held on the opposite side. It was troublesome to walk. On the contrary, when fixing the driver seat, it is troublesome for the operator to adjust the height when aligning the support member with the locking position and the position of the hole for inserting the pin for locking. . Further, even when manufacturing a forklift, it is necessary to provide pedestals for pivotally supporting or locking the support members on the left and right head guards respectively, and it is important to ensure the dimensions and alignment accuracy when assembling the pedestals. It was difficult.

In view of the above problems, the present invention makes it easy to retract the driver seat when opening and closing the engine hood.
Further, it is a technical problem to be solved to provide a driver seat support structure having a structure that can easily secure dimensional accuracy during manufacturing.

(Means for Solving the Problems) The present invention takes the following means in order to solve the above problems.

That is, the support member that supports the seat stand to which the driver seat is attached is attached to the hole for lifting the counter weight.

(Operation) According to the driver seat support structure of the present invention by the above-mentioned means, the operator can bring the driver seat to the retracted position without moving greatly when opening the engine hood. In addition, when closing the engine hood, the driver seat can be easily aligned with the driving position. Further, the head guard is not required to be modified in manufacturing, and the accuracy of dimensions, position and the like can be easily obtained, which facilitates manufacturing.

(Embodiment) An embodiment embodying the present invention will be described below with reference to FIGS. 1 to 8.

<Embodiment 1> As shown in FIG. 1, in a driver's cab 25 surrounded by a head guard pillar 20 of a stilt-type forklift 10, a general forklift 12 (first The floor surface 30 is formed at a position higher than that (see FIG. 9). A handle 26 for operating the forklift 10, a shift lever 27, a pedal 28, and the like are arranged on the stay 35. The engine hood 31 is a radiator cover 2 that is bolted between the head guard pillars 20 and 20.
It is rotatably attached to 1 by a hinge 22,
At the time of engine inspection, a plate 38 rotatably attached to a stay 35 by a hinge 37 is flipped forward and then the engine hood 31 is flipped backward. In this portion, the stay 36 as shown in FIG. 2 and the front wall surface 39 as shown in FIG. 3 with its cross section partially cut away are the supporting shafts of the engine hood (rotating shaft of the hinge 22).
The engine hood 32 may be configured to have a certain distance from the engine hood 32.

A driver seat 40 is mounted above the engine hood 31 so as to be positionally adjustable in the front-rear direction with respect to a seat stand 41, and the seat stand 41 is fixed to a hanging hole 51 of a counterweight 50 by a bolt 52. The support member 60 is slidable laterally with respect to the support member 60.
Is attached so as to be rotatable about the axis (see FIG. 6). The support member 60 includes a main pipe 61 and a sub pipe 62, and a support bracket 42 fixed to a central portion of the seat stand 41 is slidable with the main pipe 61.
Are arranged so as to wrap around (see FIGS. 4 and 5). Side walls 43 are formed at the left and right ends of the seat stand 41, and a cushioning member 45 made of rubber or other resin is fixed to the rear end portion 44 of the side wall 43 in the machine crossing direction. The seat stand 41 is configured to be supported via the member 45 (see FIG. 6). The buffer member 45 may be fixed to the sub pipe 62 instead of the side wall 43. Also, the main pipe 61 has grooves at appropriate intervals.
63 is formed, and the seat stand is fitted in the groove 63.
A lock pin 64 provided on 41 is engaged to fix the driver seat 40 in the left-right direction.
The lock pin 64 is always biased by a spring 65 to a position where it can be engaged, and when the driver seat 40 is moved left and right, the pin 64 should be pulled to disengage and move (see FIG. 7). .

In the driver seat support structure of the first embodiment configured as described above, when the engine hood 31 is opened, the driver seat 40 is lifted, pivoted around the main pipe 61 to be retracted rearward, and thereafter, It is sufficient to open the engine hood 31 as described above.

The driver seat configured in this manner can be moved laterally, and if the attachment or luggage is large and obstructs the visual field in the front, the visual field can be secured by laterally moving. Further, the weight of the driver is applied to the counterweight during the cargo handling work, which contributes to the stability of the vehicle body.

Second Embodiment The structure of the forklift 11 according to this embodiment has already been described in the first embodiment.
The forklift 10 is similar to the above forklift 10 and different parts of the configuration will be mainly described below.

As shown in FIG. 8, a driver seat 46 is mounted above the engine hood 33 of the forklift 11 of the present embodiment so as to be positionally adjustable in the front-rear direction with respect to the seat stand 47. The counter weight 50 is attached to the first support member 66 by a support bracket 48 fixed to a seat stand 47 so as to be rotatable about a first support member 66 fixed to a suspension hole 51 of the counterweight 50 by a bolt 52. A second support member 67 is arranged on the lower front portion of the seat stand 47. Both ends of the second support member 67 are connected to the lower portion of the seat stand 47 and the upper portion of the engine hood 33 by a connecting portion 49, respectively.

In the driver seat support structure of the second embodiment configured in this way, when the engine hood 33 is opened, either the driver seat 46 or the engine hood 33 is lifted to have the connecting portions 49 at both ends. Second support member
Both the driver seat 46 and the engine hood 33 can be rotated to the retracted position by the 67. For this reason, the effort for opening and closing the engine hood is reduced, which is convenient.

In addition, although the second support member 67 has been described as a single one in this embodiment, it may be composed of a plurality of two or more.

(Effect of the Invention) As described in detail above, according to the present invention, the operator does not have to move greatly when opening and closing the engine hood, and there is no difficulty in positioning for fixing the driver seat. . Furthermore, the accuracy of the size and position of each member for supporting the driver seat is easy to obtain, and the manufacture is easy. As described in detail above, the present invention has excellent effects.
