Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is a cover for machinery storage rooms such as engines of construction machinery (hereinafter referred to as A device for holding the hood open (hereinafter referred to as a hood) (referred to as an open lock device).

0002

[Conventional technology]

Figures 10 and 11 show side views of conventional hood open lock devices. FIG. 10 shows the hood a in a closed state, and an open lock device c is provided on the side of the machine storage chamber b. d is a handle. When the hood a is opened in the direction of the arrow A, the hood a opens to the position indicated by the two-dot chain line a ₁ with the hinge e as the center, as shown in Fig. 11, and the lower end of the stay g moves from the position g ₁ shown in Fig. 6. When the hood a is moved almost horizontally along the groove h to the position g ₂ and the hood a is gently lowered, the lower end of the stay g moves from the position g ₂ along the lower part of the groove h due to the weight of the stay g. After moving to position _g3 , hood a is automatically locked in the state shown by _a2 .

0003

[Problem that the idea aims to solve]

In the conventional hood open lock device shown in FIGS. 10 and 11, as described above, when the hood a is opened to the state _a1 shown by the two-dot chain line in FIG. Since it is rotated to state ₂ and locked, the angle α shown in FIG. 11 is quite large, and in one specific example is about 10 degrees. Therefore, if there is no obstacle indicated by the symbol i in Fig. 11, a support rod found on the hood of an ordinary car would be sufficient, but if there is an obstacle i, the above angle α increases and the angle α shown in Figs. Although there were examples of such prior art, there was a major problem in that the opening angle (indicated by the symbol β in Fig. 11) required for work and inspection of the machine storage room b was small, resulting in poor maintainability.

0004

[Means and actions for solving the problem]

This idea was made in view of the above, and has a groove 51 on the side of the machine storage room. An L-shaped bracket 50 is provided, and one end of a stay 60 is rotatably attached to the hood. The parallel plate portion 62 of the stay 60 is connected so that it fits into the groove portion 51 and moves while being guided. The L-shaped bracket 50 has a bottom part so that it comes into contact with the hood when it is fully opened. 52, and the stay 60 has a lower end L portion 63, which abuts when the hood is open and locked. As shown in FIG. By doing this, the opening angle when the hood is fully opened and when the hood is opened. The difference between the opening angle and the opening angle when the machine is in the open position has become extremely small, making it difficult to inspect and maintain the machine storage room. It makes it easier.

【Example】

Embodiments of this invention will be described below based on the drawings. Figure 1 is based on this idea. FIG. 2 is a side view for explaining the open lock device of the hood 10, with the hood 10 closed. The open lock device 30 is installed on the side of the machine storage room 20. Ru. 40 is a handle. And the L-type, which is the main component of the open lock device 30. Perspective views of the bracket 50 and the stay 60 are shown in FIGS. 2 and 3. L type bracket 50 is fixed to the side of the machine storage room 20. 70 in Figure 1 is fixed to the hood 10. The stay 60 is rotated by the pin part 61 in the pin hole 71 at the lower end of the lever. The parallel plate portion 62 of the stay 60 is mounted in the groove portion 51 of the L-shaped bracket 50. They become addicted to it and are restricted from exercising. 80 is for pivoting the rotation of hood 10 It's a hinge.

[0006] In Figure 1, when the hood 10 is opened in the direction of arrow A, the stay 60 rotates in the direction of arrow B. However, when it is fully opened, it becomes the state shown in FIG. 4, and the opening angle at this time is indicated by γ. So The details of the C part are shown in FIG. 5, and the view taken in the direction of the D arrow in FIG. 5 is shown in FIG. Note that in Figure 6 FIG. 5 is a cross-sectional view taken along line E-E. Then, leave hood 10 fully open. As shown in FIG. The hood 10 is fully opened when the hood 10 comes into contact with the

[0007] If the hood is gently lowered from this state, it will be in the state shown in Figure 7. The opening angle at the time is indicated by δ, the details of the F part are shown in Fig. 8, and the view from the G arrow in Fig. 8 is shown in Fig. 9. . Note that FIG. 8 is a cross-sectional view taken along line H--H in FIG. 9 . Then, remove the hood 10 from Figure 7. In the open lock state shown in Figure 8, the upper part of the L-shaped bracket 50 is The surface portion 53 and the lower end groove portion 64 of the stay 60 are in contact, and the hood 10 is in an open lock state. It becomes a state.

[0008] In this embodiment, the opening angle γ when the hood 10 is fully opened and the The difference from the opening angle δ in the open lock state is about 1 degree, which is different from the above conventional technology. It is much smaller than the approximately 10 degrees in the engine room, so it is useful for maintenance work and inspection of the engine room Maintainability is improved because the opening angle δ of the hood in the open lock state required for will improve accordingly.

[0009]

[Effect of the idea]

This device is constructed as described in detail above, and the hood in the open lock state is The opening angle of the door can be made larger than before, making it easier to carry out maintenance work inside machinery storage rooms, etc. This has the great effect of making inspection easier and significantly improving maintainability. Ru.
