Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a locking device that can hold a vehicular lid in a slightly open half-open position.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a semi-open holding lock device that holds a lid supported in an openable and closable manner at the front of a cabin of a truck or the like in a semi-open position slightly opened from a fully-closed position is shown in FIG. The hook member (14) having the hook portion (14a) that can be engaged with the striker (13) fixed to the lid (12) side on the base member (11) fixed to the side can be rotated by the shaft (15). It is configured to be pivotally attached.
[0003]
When the lid (12) is in the half-open position, the hook member (14) inserts a hand through the gap between the lid (12) and the vehicle body, and performs a release operation to disengage the hook portion (14a) from the striker (13). A handle portion (14b). The lid (12) is in the fully closed position (A) engaged with the fully closed lock device provided separately from the half open holding lock device, and when the fully closed lock device is opened from the driver's seat. Further, the striker (13) is engaged with the hook member (14) of the locking device for holding the half-open state, and is held in a slightly open half-open position (B) and a fully opened position (not shown). .
[0004]
[Problems to be solved by the invention]
However, when the lid (12) moves to the overstroke position (D), which is further overstroked from the fully closed position (A), the hook member (14) has two points. Sufficient layout space between the lid (12) and the hook member (14) so that the hook member (14) and the lid (12) do not interfere even when moved to the full operating position (C) indicated by the chain line It is necessary to ensure.
[0005]
If this layout space is not enough, when the lid (12) is suddenly closed, the lid (12) reaches the overstroke position (D) and the striker (13) rebounds when it passes through the hook part (14a). As a result, the hook member (14) may reach the full operating position (C), and the operation portion (14b) of the hook member (14) may interfere with the lid (12), thereby damaging the painted surface of the lid (12). is there.
[0006]
The present invention has been made in view of the above-described problems of the prior art, and has a simple configuration that prevents interference between the hook member and the lid and can save space. It aims to provide a locking device.
[0007]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) It is pivotally attached to the vehicle body, and has a hook portion that can restrain the lid at a half-open position by engaging with a striker fixed to a lid that is openably and closably supported by the vehicle body at one end. A hook member that has a handle portion for releasing the hook portion from the striker and is movable between a standby position where the hook portion can be engaged with the striker and a full operation position where the hook portion is released from the striker. In the vehicular lid locking device provided, when the lid further moves in the door closing direction from the closed position, the striker contacts the hook member to prevent the hook member from moving to the full operating position. A stopper member is provided.
[0008]
(2) In the above item (1), the stopper member is provided at a portion located between the pivot of the hook member and the hook portion.
[0009]
(3) In the above item (1) or (2), the stopper member is formed by fitting an elastic body to a bent portion obtained by bending a part of the hook member.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
In FIG. 1, (1) is a lid that is supported so as to be openable and closable at the front of a cabin such as a truck, and (2) is a fully-closed locking device that holds the lid (1) in the fully closed position (E). A base plate (4) fixed to the vehicle body (3), which is a locking device for holding the lid (1) in the half open position (D) slightly opened when the (not shown) is opened. A hook member (6) pivotably attached to the base plate (4) by a horizontal shaft (5), and a spring for biasing the hook member (6) in the engaging direction (counterclockwise in FIG. 1) (7) and a stopper member (8) provided on the hook member (6).
[0011]
The hook member (6) has a hook portion (6a) that can be engaged with and disengaged from the striker (9) fixed to the lid (1), and an operation portion (6b) that extends downward. ) Between the standby position shown in FIG. 2 where the striker (9) can be engaged and the full operating position (G) shown by the two-dot chain line in FIG. 1 where the hook (6a) is detached from the striker (9). It is movable.
[0012]
The stopper member (8) has an elastic body (8a) such as rubber on a bent portion (6c) obtained by bending a part of the hook member (6) located between the hook portion (6a) and the shaft (5). When the lid (1) is in the fully closed position (E) when engaged with the fully closed locking device, the striker (9) comes into contact with the backlash of the lid (1). Suppress.
[0013]
When the lid (1) is in the open state, the hook member (6) is held at the standby position by the urging force of the spring (7). When the lid (1) is closed in this state, the striker (9) comes into contact with the inclined portion (6d) of the hook portion (6a), and the hook member (6) is resisted against the biasing force of the spring (7). , After forcibly moving in the release direction (clockwise in FIG. 2), which is the direction of the full operation position (G), enters the position engageable with the hook portion (6a), and the lid (1) Is held in the fully closed position (E) by engaging a fully closed striker (not shown) with the fully closed locking device.
[0014]
When the lid (1) is suddenly closed and moved from the fully closed position (E) shown in FIG. 1 to the overstroke position (F) moved further in the door closing direction, the hook member (6) has two points in FIG. Even before attempting to move to the full operating position (G) indicated by the chain line, the striker (9) comes into contact with the elastic body (8a) of the stopper member (8) and the hook member (6) is fully operated ( G) is prevented from moving in the direction, and the hook member (6) is stopped at the stop position (H) indicated by the solid line in FIG. Therefore, the hook member (6) does not move to the full operating position (G) and the handle portion (6b) does not interfere with the lid (1) as in the prior art.
[0015]
【The invention's effect】
According to the present invention, the following effects can be achieved.
(a) According to the first and second aspects of the invention, with a simple structure only, interference between the hook member and the lid can be prevented when the lid is suddenly closed, and damage to the painted surface of the lid can be prevented. At the same time, the space of the vehicle can be saved.
[0016]
(b) According to the invention described in claim 3, it is possible to prevent the contact noise from being generated when the striker contacts the stopper member.
