Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a locking device for an automobile bonnet, trunk hood, etc.

(Prior Art) There is a device of this type that hooks a mushroom-shaped striker from the orthogonal direction (such as Utility Model Application No. 61-20758), and is often used in engine hoods and the like.
In addition to the striker that ultimately locks the hood, some of such devices are equipped with a secondary locking mechanism to prevent the hood from opening immediately even if the lock is released. However, the conventional sub-lock mechanism has a separate structure from the main lock mechanism, and has to be reinstalled after the main lock is assembled, resulting in poor workability. Furthermore, since the sub-lock mechanism operates after the main lock is released, its vertical dimensions must necessarily be large, making it difficult to install it on vehicles with low noses.

(Technical Problem) The purpose of the present invention is to solve the above-mentioned problems, and to provide a hood lock device in which the main lock mechanism and the sub-lock mechanism are integrated, and the restrictions on applicable vehicle types are eliminated or significantly reduced by shortening the vertical dimension. Our goal is to provide the following.

(Technical means) The present invention that achieves the above object includes a striker 2 protruding from the hood side via a striker board 1,
A main locking mechanism 5 has a latch lever 4 attached to the vehicle body using a mounting board 3 to lock the striker 2, and a safety latch 6 that can be locked to the mounting board 3 is pivotally supported on the striker board 1. and an externally operable sub-lock mechanism 8,
This hood lock device is characterized in that a locking portion 9 is provided on a part of the mounting board 3 facing the safety latch 6 and protrudes toward the striker board 1.

(Example) To explain with the illustrated example, the striker board 1 and the mounting board 3 are formed horizontally, and have a configuration in which the main lock mechanism 5 is arranged on one side and the sub-lock mechanism 8 is provided on the other side. . First, the main locking mechanism 5 is attached to the hood-side striker board 1 at the proximal threaded portion 1.
In order to receive the striker 2 which is attached by nuts 11 and 12 with 0 and its head 13, the striker enters through the notch 15 of the cylindrical striker guard 14 attached to the vehicle body side mounting board 3 and the head 13 is inserted.
The latch lever 4 is always biased in the locking direction by a lock spring 17 attached using a main shaft 16 which is pivotally supported on the mounting board 3.

Next, the secondary locking mechanism 8 is provided with a rotatable safety latch 6 which is pivotally supported by a horizontal shaft 19 on a hanging piece 18 provided on the other side of the striker base plate 1, and this safety latch 6 is attached to a tip hook portion. 6a, and is always biased in the locking direction by an auxiliary lock spring 20 attached using the horizontal shaft 19, but the operation part 7 provided at the base end can be operated against the spring 20. The lock can be released by

Between the hook portion 6a of the safety latch 6 and the locking portion 9 of the mounting board 3 with which it locks, there is a space S corresponding to the movement of the hood side when the main locking mechanism 5 is in the unlocked state. However, in the present invention, this space S is obtained by bending the mounting board 3 so as to protrude toward the striker board 1 to form the locking part 9 (see Fig. 3). . Further, in order to prevent the protruding locking portion 9 from coming into contact with the upper striker board 1, the locking portion 9 is narrowed to a dimension necessary and sufficient for the latch hook portion 6a, and at the same time, the width of the locking portion 9 is narrowed to a size necessary and sufficient for the latch hook portion 6a. A recessed portion 21 is provided in the. Note that 22 is a convex portion provided on the locking portion 9, and is provided as necessary to avoid contact with the hook portion 6a.

In each figure, 23 is a coil spring interposed between the striker board 1 and the spring receiver 24 of the striker 2, 25 is a stopper for the latch lever 4, 26 is a wire for unlocking the latch lever 4, and 27 is the attachment of the striker board 1. hole, 28 is the mounting board 3
A similar hole is shown in the figure.

(Operations and effects of the invention) In the present device having the above configuration, the striker 2 of the main locking mechanism 5 is connected to the striker guard 14.
The safety latch 6 of the sub-locking mechanism 8 is in a double lock state facing the locking part 9 of the striker board 1 from below, and the wire 26 is pulled and the striker 2 is locked from the latch lever 4. When the hood is removed, the hood release mechanism (not shown) works and the striker board 1 side tries to move away from the mounting board 3, but the hook part 6a of the sub-locking mechanism 8 is locked to the locking part 9, so the hood cannot be removed any more. The hood is prevented from opening, and the hood can be opened by operating the operating section 7.

Therefore, the locking portion 9 to which the safety latch 6 of the sub-lock mechanism 8 locks is located closer to the striker board 1 than the mounting board 3.
Since the safety latch 6 protrudes relative to the mounting base plate 3 and thereby brings both boards 1 and 3 closer together, the size of the safety latch 6 is reduced, and the space occupied by the safety latch 6 below the mounting base plate 3 is also significantly reduced.

Therefore, according to the present invention, the main and sub lock mechanisms 5,
8 is integrally installed between the same members, this solves the problem of having to adjust the installation dimensions and install the sub-lock mechanism after installing the main lock mechanism, which significantly improves work efficiency. In addition, the locking part 9 of the sub-lock mechanism 8 protrudes upward, and the vertical dimension of the safety latch 6, which does not protrude downward, is reduced, resulting in remarkable effects such as being applicable to vehicle models with a low nose. Demonstrated.
