BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt cylinder cover for covering a tilt cylinder of a forklift.

[0002]

2. Description of the Related Art In a general forklift, a tilt cylinder for tilting a mast forward and backward passes through a hole in a front protector at the front of the driver's seat and is supported by a tilt pin on a support bracket installed on the floor of the driver's seat. It is rotatably supported.

[0003]

However, in the conventional general forklift, the holes of the tilt cylinder and the front protector are exposed because the holes of the tilt cylinder and the front protector are exposed. There is a space between the seat and the floor, leaving room for improved safety.

With respect to this problem, it is sufficient to install a tilt cylinder and a tilt cylinder cover for covering the hole. However, a screw hole for bolting is provided on the support bracket or the floor of the driver's seat, or a mounting hole for mounting. It was necessary to install the bracket separately, and in particular, mounting the tilt cylinder cover on the existing forklift required a considerable amount of work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tilt cylinder cover mounting structure in which the tilt cylinder cover can be mounted very easily.

[0006]

To achieve the above object, a tilt cylinder cover mounting structure according to the present invention is used in a tilt cylinder in which a tilt cylinder is supported by a tilt pin on a support bracket on a floor of a driver's seat. It is characterized in that a tilt cylinder cover for covering the above is supported by at least one end of the tilt pin.

[0007]

In the above structure, the tilt pin functions as a supporting member for mounting the tilt cylinder cover, and it is not necessary to provide a mounting bracket or a screw hole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

FIG. 1 shows a first embodiment of the present invention. A forklift to which the present invention can be applied is a general type, and a tilt cylinder 1 is supported by a support bracket 3 installed on a floor 2 of a driver's seat. A through hole 4 extending in the lateral direction is formed at the end portion of the tilt cylinder 1, the through hole 4 is aligned with the through hole 5 of the support bracket 3, and the tilt pin 6 is inserted into the through holes 4 and 5. Thus, the tilt cylinder 1 is rotatably supported by the support bracket 3. Also,
The tip of the tilt cylinder 1 is connected to a mast (not shown) through a hole 8 provided in the lower portion of the front protector 7 at the front of the driver's seat.

In the first embodiment of the present invention, the inner end portion of the tilt pin 6 is fixed to the tilt cylinder cover 9. The tilt cylinder cover 9 is composed of an upper horizontal portion 10 and a side vertical portion 11 depending from an inner edge of the upper horizontal portion 10, and the tilt pin 6 is fixed to the rear portion of the side vertical portion 11. ing.

When the tilt cylinder cover 9 in which the tilt pin 6 is integrated as described above is attached,
Similarly to the case where the tilt cylinder 1 is attached to the support bracket 3, first, the tilt pin 6 is inserted into the through holes 4 and 5 of the support bracket 3 and the tilt cylinder 1, and then to the side vertical portion 11 of the tilt cylinder cover 9. The bolt 13 is passed through the small hole 12 provided to support the bracket 3
It is screwed into the screw hole 14. By this bolting, the tilt cylinder cover 9 is fixed to the support bracket 3 and is supported at two points by the tilt pin 6 and the bolt 13, so that the tilt cylinder cover 9 is prevented from rotating. Furthermore, since the tilt cylinder cover 9 integrated with the tilt pin 6 is fixed to the support bracket 3, the tilt pin 6 is prevented from falling off at the same time.

Since the tilt cylinder cover 9 thus attached covers the upper part and the inner side of the hole 8 of the tilt cylinder 1 and the front protector 7, there is no possibility that the foot is caught on the lower side of the tilt cylinder 1 or the like.

In the illustrated embodiment, reference numeral 15 is a receiving plate for supporting the front portion of the tilt cylinder cover 9, and by providing this receiving plate 9,
It is also possible to use the upper horizontal portion 10 of the tilt cylinder cover 9 as a footrest. When using the tilt cylinder cover 9 as a footrest,
It is more effective to attach a rubber pad to the top surface.

The form of the tilt cylinder cover 9 is not limited to that shown in FIG. 1, but the rear part may be closed so as to cover the end of the tilt cylinder 1 and the support bracket 3, for example. In this case, there is an advantage that the uneven portion is reduced and it is difficult to catch a foot when getting on and off.

FIG. 2 shows a second embodiment of the present invention. In this embodiment, unlike the first embodiment described above, the tilt pin 6'and the tilt cylinder cover 9'are not integrated, and a screw hole 2 is formed on the end face of the tip of the tilt pin 6 '.
0 is processed.

In such a structure, when the tilt cylinder cover 9'is attached, the tilt pin 6'is inserted into the through holes 4 and 5 of the support bracket 3 and the tilt cylinder 1 on the floor 2 of the driver's seat, and the tilt cylinder cover 9 '. The bolt 22 is passed through the small hole 21 provided in the side vertical portion 11 'and screwed into the screw hole 20 of the tilt pin 6'. Further, in order to prevent rotation of the tilt cylinder cover 9 ', the front portion of the upper horizontal portion 10' of the tilt cylinder cover 9'is placed on the receiving plate 15 'of the front protector 7 and fixed by the bolt 23. .

In this second embodiment, the tilt pin 6 '
Since the tilt cylinder cover 9 ′ is bolted to the tip of the tilt cylinder cover 9 ′, the tilt cylinder cover 9 ′ also serves to prevent the tilt pin 6 ′ from coming off, and the tilt pin 6 ′ can reliably support the tilt cylinder 1. .

Further, FIG. 3 shows a third embodiment of the present invention. In this embodiment, the tilt pin 6 ″ includes the support bracket 3 and the through holes 4, 5 of the tilt cylinder 1.
, The plate 30 extending radially outward from one end thereof is bolted to the support bracket 3. Further, the tilt cylinder cover 9 ″ is provided on the upper horizontal portion 1
Side vertical portions 11 "hang from both side edges of 0", and an inverted U-shaped bearing 31 is formed on the inner surface of the rear portion of each side vertical portion 11 ". Both ends of the tilt pin 6". Of the tilt cylinder cover 9 ″ by fitting the corresponding bearing 31 into the protruding portion 32.
Is supported by a tilt pin 6 ″. The front part of the tilt cylinder cover 9 ″ is bolted to the receiving plate 15 ″ of the front protector 7, so that the tilt cylinder cover 9 ″ is a hole in the tilt cylinder 1 and the front protector 7. 8 is installed in a state of covering up.

[0019]

As described above, according to the present invention, since the tilt cylinder cover is supported by the tilt pin, in order to mount the tilt cylinder cover, a screw is attached to the support bracket or the floor of the driver's seat. No need for holes or mounting brackets. In particular, in the existing forklift, the tilt cylinder cover can be attached only by the work of substantially replacing the tilt pin, which is very effective.

Further, after the tilt cylinder cover is installed, the space between the tilt cylinder and the floor of the driver's seat or between the tilt cylinder and the hole of the front protector is closed to improve the safety and the tilt cylinder. Since the cover can also be used as a footrest,
The driving environment is also improved.
