JP2000103594A - Driver's seat door of reach type fork lift - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate inspection and maintenance of equipment and improve working efficiency by bending a door at nearly a right angle at the middle part to form into a shape covering from the rear face of a vehicle to the side of a driver's seat, fixing the door to a vehicle frame by hinges, and opening/ closing it by a door lock. SOLUTION: A door lock 8 is formed so as to pinch a guide groove to be rotatable against the guide groove, and provided with upper and lower links always energized with a spring. When a door is closing, a bracket fitted to a vehicle frame enters the guide groove, pushes the upper and lower links to open, and it is fitted in a prescribed engaging part to lock the door. The door lock 8 is fitted to the end part of the door 13, but the door bent at nearly a right angle at the middle part is rotationally moved to close, the door lock 8 is arranged slantingly against the door 13 so as to be locked along the locus 16 of the door. Further the fitting frame 17 of the door lock 8 is provided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door of a driver's seat for covering main equipment in a reach type forklift.

[0002]

2. Description of the Related Art A reach-type forklift is provided with an arm having a front tire mounted at an end thereof, extending forward of a vehicle, and moving a cargo-handling device equipped with a lift and tilt mechanism back and forth along the arm to perform cargo-handling. This is a forklift that excels in front-to-back stability and has a small turn and is used for work inside buildings and the like.

In this reach type forklift,
As shown in FIGS. 5 and 6, main devices 3 such as a traveling and cargo handling device are arranged on the side of the driver's seat 2, and these devices 3 The door 5 is stopped and can be opened and closed on the rear surface of the vehicle, and is covered with a driver's side cover 6 which is attached to the frame 4 of the vehicle with bolts. In the figure, 8 is a door lock, 9 is a top cover, 10 is a running handle, 11 is a brake rod,
Reference numeral 12 denotes an operation pedal of the brake rod.

The traveling and cargo handling equipment of this type of vehicle requires daily inspection and maintenance, and the door 5 is opened for inspection and maintenance. 5 can be opened from the rear side of the vehicle 1. Inspection and maintenance from the side of the driver's seat 2 required removal of the driver's side cover 6 attached with bolts, which was troublesome and low in work efficiency. Further, since the door 5 and the driver's seat side cover 6 are separated, the number of parts is increased and the cost is increased.

[0005]

A cover on the side of the driver's seat of a reach-type forklift can be easily opened and closed in the same manner as a door on the rear side of a vehicle, and inspection and maintenance of equipment can be facilitated to improve work efficiency. It is another object of the present invention to reduce the number of parts to reduce costs.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a door for covering main equipment of a reach type forklift, which is bent at a substantially right angle at a central portion so as to cover from a rear surface of a vehicle to a side surface of a driver's seat. The door is hinged to the vehicle frame and opened and closed by a door lock. Further, the door lock is arranged to be inclined with respect to the door so that the door is locked along the path of the door.

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a schematic view of a reach-type forklift equipped with a door according to the present invention as viewed from the rear, and FIG.
It is a top view which shows the driver's seat part along X-ray. In addition,
The same parts and parts as those of the conventional type are denoted by the same reference numerals. In the figure, reference numeral 13 denotes a door whose central portion is bent at a substantially right angle, and has a shape that covers the rear surface of the vehicle and the side surface of the driver's seat. The door 13 is rotatably hinged to the vehicle frame 4 and is locked by a door lock 8 when the door is closed.

The door lock 8 has a guide groove, and upper and lower links which are rotatable so as to sandwich the guide groove and are always urged by a spring. The bracket attached to the frame 4 enters the guide groove, pushes up and down the upper and lower links, fits into a predetermined engaging portion, and locks the door, and is usually used as a door lock of a vehicle. ing.

The door lock 8 is attached to the end of the door 13. In the present invention, the door, which is bent at a substantially right angle at the center, is rotated and closed. As shown in FIG. 2, the trajectory 16 of the door 13 (FIG. 2)
Is arranged at an angle to the door 13 so as to be locked along. Reference numeral 17 denotes a mounting frame for the door lock 8. Reference numeral 18 denotes a trajectory of the guide groove of the door lock 8, and a bracket attached to the vehicle frame 4 is arranged along the trajectory 18.

FIG. 4 shows a side surface of the door 13 along the line YY in FIG. 1. A notch 14 is provided at a lower portion of the door 13, and when the door is opened and closed, the brake rod 11 and the pedal are provided. 12 to avoid interference. Reference numeral 15 denotes a notch provided at an upper portion of the door 13, and the handle of the door lock 8 is operated through the notch 15.

When the door 13 is opened and closed with the above-described configuration, the door 13 is rotated by utilizing the space of the driver's seat 2 as shown by a locus 16 in FIG. The rear side of the vehicle and the side of the driver's seat are simultaneously opened or closed by one operation. Also, door lock 8
Is locked along the trajectory 16 of the door 13, so that it is securely locked.

[00012]

According to the present invention, a door which is bent at a substantially right angle at the center and covers the rear surface of the vehicle and the side surface of the driver's seat is hinged to the vehicle and the door is locked. Equipment can now be inspected and maintained from the rear of the vehicle and the side of the driver's seat. For this reason, the complicated work of removing the bolted cover is eliminated, and the work can be performed efficiently. Further, since the conventional door and cover are integrated, cost can be reduced by reducing the number of parts.
