JPS602052Y2 - Forklift floor structure - Google Patents

Description

[Detailed explanation of the idea] This invention relates to the floor structure of a forklift.

Generally speaking, forklifts are known to have a floor structure as shown in the introduction of the Nissan battery forklift UB02 model and CYO2FF vehicle in Nissan Service Bulletin No. 383, published by Nissan Motor Co., Ltd., June 1932.

Therefore, the present applicant previously published Utility Model Application No. 54-66853 (Japanese Utility Model Application No. 55-167882), in which Figs.
We have already proposed the structure shown in the figure.

That is, as shown in the first and second figures, the front side panel 1 is arranged in a rearward tilted state at an angle where the operator can most easily operate operating devices such as the instrument panel 8 and the steering wheel 9. It is formed at an angle at an appropriate angle.

Therefore, the floors that are placed across the upper side of the side frames 2 from the front side panels 1 on both sides are the front floor 3 that is placed on the front side panel 1 and the rear floor that is placed on the side frames 2 as shown in the figure. 4 are molded separately, and these front floor 3 and rear floor 4 are attached by butting each other.

In addition, normally, a step 5 for getting on and off the side frame 2 is formed in consideration of the ease of getting on and off the operator. It is constructed by forming a notch in the wall and joining an L-shaped step panel 6 to this notch.

In this way, the front side panel 1 of the side frame 2
When the step 5 is formed in a concave manner at the connecting portion with the step 5, the joining position of the end of the rear floor 4 is restricted to the end surface of the front axle mount plate 7, which is the inner bottom wall of the step 5.

Therefore, when connecting the rear floor 4 and the front axle mount plate 7, as shown in FIG. Taking this into consideration, the end of the rear floor 4 is set to fit within the thickness of the upper end surface of the front axle mount plate 7, and the end of the rear floor 4 is connected to the upper end surface of the front axle mount plate 7.

Therefore, in order to properly connect the end of the rear floor 4 to the upper end of the front axle mount plate 7 within its thickness, high precision is required in assembling the side frame 2, front side panel 1, etc. High precision was also required for the machining of the 4 itself, which was accompanied by difficulties in terms of the car body structure.

Furthermore, since the upper wall of the side frame 2, which can be used as a rear floor, is cut out in order to form the step 5, the area of the rear floor 4 is narrowed, which deteriorates the operator's work efficiency and riding comfort. Furthermore, when getting on or off the vehicle with one's feet on the step 5, there is a risk of injury due to hitting one's legs against the upper edge of the front axle mount plate 7 and the side edges of the rear floor 4.

In addition, in FIG. 1, 10 is a counter eight, 11 is a top handle for storing an engine or battery (not shown), 12 is a seat provided on the top surface, 13 is an overboard guard, 1
4 indicates wheels.

In view of the conventional situation, the present invention further improves the 1984-6 Meibutsu No. 1984 application and expands the floor area, especially the area of the rear floor where the operator's feet are placed when getting on and off and working. The present invention provides a floor structure that can improve the ease of getting on and off the vehicle.

That is, in the present invention, as illustrated in FIGS. 4 and 5, a step 5 for getting on and off is formed in a concave manner at the joint part of the side frame 2 with the front side panel 1, and The side end extends 15 facing the upper side of the step 5 within an appropriate range that does not interfere with getting on and off the rear floor 4.
The back surface is bonded and fixed to the upper end surface of the front axle mount plate 7, and a downward folded edge 16 is formed on this extending end portion 15.

As shown by the imaginary line in Fig. 5, bracket B is welded to the upper end of front axle mount plate 7, and bolt C is welded to the upper end of front axle mount plate 7.
The rear floor 4 may be fixed by.

In this way, the extension of the rear floor 4 side end toward the step 5 side does not restrict the joining position of the rear floor 4 with the upper end surface of the front axle mount plate 7, so that the machining accuracy of the rear floor 4 and the side frame 2 and front This is not only extremely advantageous in manufacturing the vehicle body since there is no major restriction on the assembly accuracy of the side panels 1, etc., but also allows the area of the rear floor 4, which is most frequently used, to be expanded.

As mentioned above, the extending end has a downward folding edge 16.
Because of this, even if you hit the folded edges 16 with your legs when getting on and off with your feet on the step 5, you can prevent injuries caused by hitting the edges as in the past, and the ease of getting on and off can be further improved. It has practical effects.

Note that it is even more effective to prevent injuries if a cushioning material is attached to the folded edge as shown by the imaginary line.
