Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine hood stay used to support the engine hood of a vehicle in an open state.

Conventionally, the stay used in the engine hood of a forklift, for example, has a first link 3 attached to the vehicle body 1 side, as shown in FIGS. 1 and 2.
and the second link 4 attached to the engine hood 2 side.
The ends of the first link 3 are connected to each other by a connecting pin 5, and an engaging recess 6 is formed on the end surface of the first link 3, while the second link 4 has a lock pin that can be engaged and detached from the engaging recess 6. 7 is movably attached via a long hole 8. By the way, the engine hood 2 of a forklift differs depending on the vehicle model, or even if the vehicle is the same model, there are cases in which a propane gas cylinder is mounted on the top of the balance weight 9 located on the rear side of the engine hood 2, and cases in which it is not mounted. Or, depending on the presence or absence of obstacles to opening, such as when the radiator protrudes or does not protrude, there is a difference in the range that can be opened, that is, the degree of opening is different. Therefore, it is desirable that the engine hood stay be able to adjust its opening degree when assembling the engine hood. However, since the stay with the structure described above has a constant overall length, the opening cannot be adjusted during assembly, and therefore a dedicated stay must be prepared for each engine hood.

The purpose of the present invention is to provide a vehicle engine hood stay that has a variable overall length and can adjust the opening of the engine hood, in view of the conventional problems as described above. The aim is to standardize the stays for the hood.

Embodiments of the present invention will be described in detail below with reference to FIGS. 3 to 5. The engine hood stay is
As shown in the figure, the first link 11 is rotatably attached to the vehicle body side by a pin 22, and the second link 12 is rotatably attached to the engine hood 23 by a pin 24. The main body part is configured. The first link 11 is formed as if it were divided into two parts from its approximately center to the tip side, and the long piece 11
The short piece 11b is rotatably attached by a pin 13 in an overlapping state at the substantially central portion of the short piece 11b, so that the two pieces 11a and 11b can be moved toward and away from each other. That is, the first link 11 is configured to be divisible from the center to the tip, and both pieces 11a,
A plurality of divisible pin holes 14 are formed at appropriate intervals in the longitudinal direction on the mating surface of 11b, and a roughly U-shaped divisible engagement recess 15 is formed at the tip of the mating surface. There is. Further, a holding band 16 made of a leaf spring for holding both pieces 11a and 11b in a joined state is attached to the long piece 11a of the first link 11 so that its base can be rotated by a pin 17. The band 16 has both pieces 11a,
The short piece 11b is provided so as to cross the short piece 11b, and a hook portion 16a formed at the tip thereof is engaged with the edge of the short piece 11b, thereby holding the two pieces 11a and 11b in a joined state.

On the other hand, on one side of the second link 12, the first
Plate-shaped pin guides 18 are arranged in an overlapping manner with a gap C into which the link 11 can be inserted, and the base end of the pin guide 18 is fixed to the second link 12 by welding or the like. Further, a long hole 19 of the same shape is formed in the second link 12 and the pin guide 18 respectively in the longitudinal direction, and a lock pin that can be engaged and detached from the engagement recess 15 of the first link 11 is formed in this long hole 19. 20 is slidably mounted. Further, a connecting pin 21 is provided at the tip of the second link 12 and the pin guide 18, and the connecting pin 21 is fitted into one of the pin holes 14 formed in the first link 11 to connect both links. , 12 are rotatably connected.

This embodiment is configured as described above,
Therefore, when the engine hood 23 is opened, the lock pin 20 of the second link 12 is engaged with the engagement recess 15 of the first link 11 to lock both links 11 and 12 in a straight line as shown in FIG. Therefore, the engine hood 23 can be supported in an open state, and the engine hood 23 can be closed by removing the lock pin 20 from the engagement recess 15 and allowing both links 11 and 12 to rotate freely. can do.

Now, the engine hood stay of this embodiment has the long piece 1 that constitutes the first link 11 as described above.
A split pin hole 14 is formed on the joint surface between 1a and the short piece 11b.
A plurality of pin holes 14 are provided, and a second
The position of the connecting pin 21 of the link 12 can be changed, so the position of the connecting pin 21 of the link 12 can be changed.
When assembling the engine hood 23, the opening degree of the engine hood 23 can be adjusted as appropriate by changing the pin position as described above and changing the overall length of the stay. That is, when the overall length of the stay is extended, the opening degree can be increased as shown by the solid line in FIG. 5, and conversely, when the stay is shortened, the opening degree can be decreased as shown by the imaginary line in FIG.

As shown by the imaginary line in FIG. 3, the pin position can be changed by first removing the hook portion 16a of the holding band 16 from the short piece 11b to release its restraint, and then separating it into the long piece 11a and the short piece 11b. Connecting pins 21 are appropriately selected and fitted into pin holes 14, and both pieces 11 are assembled.
After joining a and 11b, the hook portion 16a of the holding band 16 is engaged with the short piece 11b again, and the operation is simple.

FIG. 6 shows another embodiment of the present invention, in which a connecting pin is inserted and removed instead of the split pin hole type of the previous embodiment. That is, the connecting pin 21 is selectively inserted into one of the plurality of pin holes 14 formed in the first link 11 and is prevented from coming out with a split pin 25 (or C ring) or the like. As in the previous embodiment, by changing the position of the connecting pin 21, the opening degree of the engine hood 23 can be adjusted.

As detailed above, in the engine hood stay of the present invention, the position of the connecting pin for connecting the first link attached to the vehicle body side and the second link attached to the engine hood side can be changed. By doing this, it is possible to adjust the opening degree of the engine hood by changing the overall length of the stay, and therefore, it is possible to adjust the opening degree of the engine hood by changing the overall length of the stay. Therefore, even if the opening degree of the engine hood is different, it is possible to change the stay length to obtain the corresponding opening degree, and it can be used as a common specification product for various engine hoods with different opening degrees. It is something that can be adapted.
