Abstract

PURPOSE:To prevent contamination of oil filler port as well as to improve the extent of appearance quality by forming a part of an engine hood with a door member capable of covering the oil filler port, and opening or closing the door member in use of a feeler jutting out of the back of this door member and a plate spring being engaged thereto. CONSTITUTION:A part of a side wall rear end in an engine hood 16 is pivotally attached to a car body 10 independently, forming it into a door member, free of opening or closing, capable of covering an oil filler port 12. When the door member 20 is closed, the oil filler port 12 is covered, and sealed by a sealing member 32, while energizing force of a plate spring 30 via a feeler 22b of a first hinge 22 is made to act as moment in the normally closed direction. On the other hand, the door member 20 is pulled, the door member 20 is lightly opened by elastic deformation in the plate spring 30 with rotation of the feeler 22b and resilient energization after going beyond a dead center. In addition, the rotation of the feeler 22b is regulated by a bending part 30a of the plate spring 30, thus the door member 20 is kept in a specified opening position.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fuel filler port positioning device for industrial vehicles, which always covers the fuel filler port to protect it from rainwater and mud baths, and when refueling. This invention relates to a fuel filler port number positioning device that allows a wide range of fuel filler ports to be exposed with easy operation.

[Prior Art] Generally, an industrial vehicle such as a forklift or a shovel loader as shown in FIG. A fuel filler port 52, which is covered with a cap, is provided in a protruding manner. The rear end portion of the side wall of the engine hood 54 is
As shown in the enlarged view of FIG. 6, a curved recess 56 is provided to expose the fuel filler port while avoiding interference. In addition,
58 is an embankment weir that prevents leaked oil from entering the engine room.

[Problems to be Solved by the Invention] However, if the fuel filler port is always exposed as described above, it not only causes rainwater to enter the tank, but also prevents the fuel tank from being surrounded by the recessed wall of the hood. Some people dislike the area around the fuel filler port because it becomes a gathering place for oil droplets, muddy water, dust, etc. and spoils the appearance. Furthermore, since there is a limit to the drawing process that makes the hood recessed, there are problems such as interference with the refueling gun, which deteriorates workability, and the hood itself is easily damaged.

The present invention aims to solve a technical problem of modifying a part of the engine hood so that the fuel filler port is always hidden except when refueling.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention forms a part of the rear end of the side wall of the engine hood into a door member for several fuel fillers that can be opened and closed independently and pivotally connected to the vehicle body. However, a novel configuration is adopted in which a leaf spring is provided which engages with a feeler protruding from the back surface of the door member and biases and holds the door member in both open and closed states.

As an embodiment of the present invention, it is more preferable in terms of sealing performance and workability that the door member is formed into a substantially right triangular shape, and the oblique side of the door member defines a boundary with the engine hood that separates the door member.

[Function] Therefore, the above-mentioned door member always maintains a closed state aligned with the engine hood due to the biasing force of the leaf spring, and the fuel filler port is completely positioned, and only the door member is easily held in the open state when refueling. As a result, the fuel filler port can be widely exposed for convenient refueling work.

[Example] Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 schematically shows the rear part of a forklift. The vehicle body frame 10 is separated from left and right with a central engine room in between, and a fuel oil tower (not shown) is integrally formed on one side. The vehicle body frame 10 has a fuel filler port 12 covered with a cap and a dam 14 that surrounds the fuel filler port 12 in a semicircular shape. 1
Reference numeral 6 denotes an engine hood that can be expanded around the rear edge of its upper surface as a pivot, and is seated on the vehicle body frame 10 while covering the engine room. A part of the upper part of the side wall wide end portion of the engine hood 16 is in contact with the rear column 18 of the head guard,
The portion below it is obliquely cut away so as to widely expose the fuel filler port 12. A door member 20 that supplements the missing portion is installed so that it can be opened and closed independently. The structure related to the door member 20, which is the main part of the present invention, is shown in FIGS.
This will be roughly explained in detail based on FIG.

The door member 20 is formed into a substantially right triangular shape with a curved edge 20a around the entire circumference, and has three bosses 22a extending at intervals on its inner surface, and a tenter further extending from between the bosses 22a. 22
A first hinge 22 with b is fixed. On the other hand, there is a spacer 2 on the inner surface of the rear column 18 of the Radguard.
4, and the three bosses 26a extending at intervals are connected to the boss 22 of the first hinge 22.
A spring pin 28 is fixedly inserted into the spring pin 28, and the door member 20 is pivotally connected to the rear column 16 so as to be able to open and close independently. 3
0 is connected to the second hinge 26 and is always connected to the tentacle 22b.
A bent portion 3 that is a leaf spring that interferes with the contactor 22b and biases and holds the door member 20 in two open and closed states through the contactor 22b.
It is equipped with 0a. In addition, 32 is the curved edge 20 of the door member 20.
A is a seal member attached to the entire area a, and when the door member 20 is in the closed state, the upper surface of the vehicle body frame 10, the rear strut 1
8 and a curved edge 16a provided in the oblique cutout portion of the engine hood 16, respectively.

Therefore, in the normal state, by closing the door member 20, the fuel filler port 12 is completely positioned and protected from direct rainwater, and at the same time, due to the connection with the sealing action of the seal member 32, the door member 20 is sufficiently closed to the engine hood. It functions as part of 16. In addition, the door member 20 in the closed state has a first
The biasing force of the leaf spring 30 via the feeler 22a of the hinge 22 is
Since it always acts as a moment in the closing direction (clockwise in the figure), the door member 20 is maintained in a stable closed state without reacting to vehicle vibrations (FIG. 3).

When refueling, for example, if the door member 20 is pulled by using the sealing gap with the upper surface of the vehicle body frame 10, the tentacle 2
The door member 20 is easily opened due to the elastic deformation of the leaf spring 30 accompanying the rotation of the leaf spring 2b and the repulsive force after the leaf spring 22b passes the dead center, and the contact 22b is opened at the end of the bent portion 30a of the leaf spring 30. By restricting rotation, the door member 20 is held in a predetermined open position (FIG. 4). Thus, fuel filler port 12
are widely exposed, and the refueling operation can be carried out smoothly and easily without causing interference between the engine hood 16 and the refueling gun.

Furthermore, when the engine hood 16 is opened for maintenance and inspection of engine-related equipment, the door member 20 is opened first, and after the work is completed, the door member 20 is closed after the engine hood 16 is restored. If you do this, both parts 1
6.20 unnecessary interference can be avoided. In addition, in the above-mentioned embodiment, the door member 20 is
Although the explanation has been made regarding the form in which the door member 20 is opened and closed, it is also possible to make a part of the door member 20 concavely curved as appropriate, or to attach a simple knob or the like to facilitate opening and closing.

[Effects of the Invention] As described in detail above, the present invention forms a part of the rear end of the side wall of the engine hood into a door member for storing a number of fuel fillers that can be opened and closed independently and pivotally connected to the vehicle body. Since the door member is biased to be held open and closed by a leaf spring, the fuel filler port is completely located within the engine hood and is reliably protected from rainwater and a bath of mud. Along with
By eliminating the fuel filler port from view, the appearance of the vehicle can be further simplified. Moreover, since the door member is biased and held in both the open and closed states, it is possible to maintain a stable closed position at all times without responding to the movement of the vehicle.
