Description

[Detailed description of the invention] This invention relates to a tightening device for opening/closing members installed in a vehicle, and the tightening is released when the vehicle receives an impact and the mounting part of the tightening device is significantly deformed. This provides a tightening device that will never cause problems.

In conventional cab-over type automobiles, as shown in FIGS. 1 and 2, a seat 4 is mounted on an engine cover 3 which is connected to a vehicle body 1 by a hinge 2 and can be opened and closed. many.

This engine cover 3 is designed to be flipped upward when inspecting and servicing the engine.

At a position opposite to the free end of the engine cover 3, a tightening device A is provided which is connected to the free end and tightens the engine cover 3 into the closed state.

As shown in FIG. 2, in this tightening device A, a catch bundle 7 is pivotally supported by a pin 70 on a bracket 5 fixed to the vehicle body, and a catch ring 6 is attached to the catch bundle 7.
and a hook 8 provided at the free end of the engine cover 3 are configured to engage and disengage.

By the way, the conventional tightening device A prevents the engine cover 3 from being deformed due to deformation of the vehicle body 1 and the engine cover 3 due to the inertia of the seat 4 on which a passenger is seated when the automobile receives a large impact.
If the free end side of the catch ring 6 is displaced forward, there is a risk that the catch ring 6 will come off from the hook 8.

The present invention was devised to eliminate such inconveniences, and the catch ring 6 is provided with a sub-catch ring, and the hook 8 is provided with a locking piece protruding in the direction of the sub-catch ring, so that it can be opened and closed. The hook 8 together with the engine cover 3 which is a component
Even in the event that the hook 8 and the catch ring 6 are disengaged due to displacement, the locking piece and the sub-catch ring engage to prevent the engine cover 3 from opening.

Embodiment B in which the present invention is applied to the engine cover tightening device will be described below with reference to FIGS. 3 to 6.

As shown in FIGS. 3 and 4, a vehicle body 1 serving as a fixing member
A single-shaped bracket 5 is fixed to the top by welding or the like.

The base of the catch handle 7 is rotatably supported at the tip of the bracket 5 via a pin 70.

A rectangular catch ring 6 is rotatably attached to the catch handle 7.

Both ends of a U-shaped sub-catch ring 60 are welded to the lower surface of the tip of the catch ring 6, and the center portion thereof crosses the inside of the catch ring 6.

On the other hand, a hook 8 rising upward is fixed to the free end of the engine cover 3, which is an opening/closing member.

A locking piece 9 is welded to the lower surface of the proximal end of the hook 8, and the tip thereof is slightly inclined upward and protrudes in the direction of the catch handle 7. This protrusion is located in front of the catch ring 6 when the device is in the tightened state. It enters the catch ring 6 from below and extends upwards of the sub-catch ring 60, and its tip edge is located slightly closer to the hook 8 than the sub-catch ring 60.

Note that 31 in the figure (FIG. 4) is a cushion rubber provided on the lower surface of the engine cover 3.

In the tightening device B having the above configuration, in order to close the engine cover 3 and tighten it integrally with the vehicle body 1, as shown in FIG. 7 and the catch ring 6 are set to the dashed line position, and the catch handle 7 is rotated about the pin 70 to the solid line position, so that the catch ring 6 is also moved to the solid line position, whereby the vehicle body 1 and the engine cover 3 are integrated. tightened.

By the way, in this tightening device B, if the engine cover is deformed or displaced due to an impact as shown in FIG. 5 and its tip moves forward, and the hook 8 moves forward accordingly, the catch ring 6 is further away from hook 8, but
The locking piece 9 moves forward in the direction of the catch handle 7 than the sub-catch ring 60 and blocks the upper part of the sub-catch ring 60, and engages with the sub-catch ring 60 when the catch ring 60 moves in the removal direction, that is, upward. The positional relationship is as follows.

Therefore, even if the engagement between the catch ring 6 and the hook 8 becomes loose and the catch handle 7 rises as shown by the broken line, the sub-catch ring 60 abuts the locking piece 9, causing the catch ring 6 to hook into the hook. 8, the engine cover 3 will not become unlocked.

Further, as shown in FIG. 6, when the displacement of the engine cover and the hook 8 is large, the tip of the locking piece 9 collides with the bracket 5, which bends the bracket 5 and absorbs the impact. 6 and the hook 8 are regulated.

Then, the locking piece 9 and the hook 8 return in the direction away from the bracket 5 due to the springback of the engine cover 3, and the hook 8 returns to the position indicated by the broken line in the figure.
Since the catch ring 6 can be replaced by the catch ring 6, safety can be more completely ensured.

Of course, at this time, the sub-catch ring 60 is located below the locking piece 9 and prevents the catch ring 6 from coming off.

As described above, the present invention is applied to an engine cover tightening device for a cab-over type automobile. A device for tightening an opening/closing member to a fixed part of a vehicle includes a sub-catch ring and a locking piece that engage with each other to prevent the release when the opening/closing member is displaced and the tightening is released. They are characterized by being provided on the catch ring and the hook, respectively, and contribute to ensuring the reliability of the device and the safety of the occupants even when the vehicle is subjected to large deformation due to impact or the like.

Claims (1)

[Scope of utility model registration request] Tightening of an opening/closing member in which a catch bundle is pivotally attached to a bracket fixed to a fixed member of a vehicle, and a catch ring is pivotally attached to the catch bundle to engage and disengage from a hook of an opening/closing member attached to the fixed member so as to be openable and closable. In the device, a sub-catch ring is provided at the tip of the catch ring so as to cross the inside of the catch ring, and the hook is provided with a sub-catch ring that enters the catch ring from below the catch ring when the device is fastened and is directed upward from the sub-catch ring. A protruding locking piece is provided to prevent the catch ring from coming off the hook as the locking piece blocks the upper part of the sub-catch ring when the opening/closing member moves toward the catch bundle due to a vehicle collision, etc. 1. A tightening device for an opening/closing member, characterized in that it is configured to prevent this.
