Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a vehicle hood lock device.

(Prior Art) Conventionally, as a bonnet lock device for a vehicle, for example, as disclosed in Japanese Utility Model Publication No. 61-159570.
A bonnet striker attached to the bonnet, a fork lever rotatably attached to the vehicle body via a bonnet lock base, and a fork lever enabling and disengaging the bonnet striker, and rotatably attached to the bonnet lock base, A claw lever for holding the fork lever in an engaged state, and a cutout portion for allowing a wire member, one end of which is connected to an operation member in the vehicle compartment, to be inserted into the bonnet lock base, and the claw lever. A lower end of the wire member and an opening that allows the other end of the wire member to be connected to a claw lever,
By the pulling operation of the wire member by the operating member,
It is known that the claw lever is pivotally operated with respect to the fork lever in a direction to release the engaged and held state, and then the bonnet striker and the fork lever are disengaged from each other to open the bonnet. An antitheft bracket that covers the lower end of the claw lever and the wire member (the other end) from below is attached to the lower part of the opening of the bonnet lock base. The antitheft bracket allows a radiator grill, etc. Preventing the lower end of the claw lever from being pushed by a long and narrow tool such as a screwdriver or wire inserted from above, so that the claw lever is not tampered with in the direction of releasing the engagement holding state with respect to the fork lever. I have to. Further, the connection between the claw lever and the wire member is performed by rotating the claw lever in the direction of releasing the engaged and held state with respect to the fork lever, and the lower end of the claw lever is moved forward from the opening of the bonnet lock base. It is done by exposing it to.

Further, there is also one in which, after the claw lever is connected to the wire member, a clip member is attached to the cutout portion of the bonnet lock base to close the cutout direction to prevent the wire member from falling off.

(Problems to be solved by the invention) However, in the above-mentioned conventional one, the opening of the bonnet lock base in front of the lower end of the claw lever necessary for connecting the claw lever and the wire member is the lower end of the claw lever. Since only the portion is covered with the anti-theft bracket from below, the wire member in the bonnet lock base is exposed outward (forward) from the opening. Therefore, when the wire member is pulled by a long tool such as a screwdriver or wire inserted from the front such as the radiator grille through the opening of the bonnet lock base, the lower end of the claw lever is pressed like the fork. There is a problem in that the lever is illegally rotated in a direction to release the engaged and held state, so that the hood is released and the mounted parts in the engine room are stolen.

Therefore, in order to solve the above problems, the front end surface of the anti-theft bracket is once extended forward from the front end surface of the bonnet lock base, and then the upper end surface is moved upward.
A side gap is provided between the bonnet lock base and the anti-theft plate by extending the side end faces sideways so that the claw lever and the wire member can be connected through this gap and the bonnet lock It is conceivable to cover the opening of the base from the front to prevent entry (insertion) of a long and narrow tool such as a driver or wire from the front through the opening. However, even in this case, the wire member can be seen (exposed) from an oblique direction (oblique side, obliquely upward, etc.) through the gap between the anti-theft plate that covers the opening from the front and the bonnet lock base. Therefore, as long as the wire member is visible, there is a risk that the wire member will be illegally pulled by taking some means (for example, bending the wire in accordance with the gap).

The present invention has been made in view of the above points, and an object of the present invention is to make an opening of the bonnet lock base without a gap after connecting the claw lever and the wire member by appropriately improving the clip member. By closing the claw lever, the connection between the claw lever and the wire member can be performed smoothly without any support, and the pulling operation of the wire member by a tool with a thin tip can be reliably prevented to prevent the mounted parts in the bonnet. It seeks to prevent theft.

(Means for Solving the Problem) In order to achieve the above object, a solution means of the present invention is a bonnet striker attached to a bonnet, and a bonnet lock base rotatably attached to a vehicle body through a bonnet lock base.
It is premised on a vehicle bonnet lock device that includes a fork lever that allows the bonnet striker to be engaged and disengaged, and a claw lever that is rotatably attached to the bonnet lock base and that holds the fork lever in an engaged state. . The bonnet lock base has a notch for allowing a wire member, one end of which is connected to an operating member in the vehicle compartment, and a lower end of the claw lever to be opened forward, and the other end of the wire member to be a claw lever. And an opening that can be connected to. Further, a clip member for closing the notch to prevent the wire member from slipping off is attached to the notch, and an antitheft plate for closing the opening in a substantially sealed state is integrally provided on the clip member. It is what

(Operation) According to the present invention, according to the present invention, the anti-theft plate is provided integrally with the clip member attached to the cutout portion of the bonnet lock base after the claw lever and the wire member are connected. Since the opening of the bonnet lock base is closed in a substantially airtight state with no gap, the connection between the claw lever and the wire member from the opening is smoothly performed without any support, and the connection with the claw lever is also made. After being made, the wire member is completely shielded by the anti-theft plate and cannot be seen from the opening. For example, a radiator grill or the like can be used for a long tool such as a screwdriver or wire (for example, the wire is bent to fit the gap). However, even if an attempt is made to insert it, it will be blocked by the anti-theft plate that closes the opening without a gap. For this reason, pulling of the wire member by an elongated tool such as a screwdriver or a wire is reliably prevented, and in the same way as when the lower end of the claw lever is pressed, it is illegal to release the engagement holding state with respect to the fork lever. It cannot be rotated.
