Description

  The present invention relates to a lid locking device such as a filler lid for a vehicle and an opening / closing device using the same, and can open / close the lid relatively easily and reliably.

2. Description of the Related Art Conventionally, an automobile filler lid device using a locking means having a push-lock / push-return type locking piece is known (page 2, column 4, lines 14 to 18 of Patent Document 1, FIG. 1).
The lid is pivotally supported at the opening so as to be openable and closable, and is urged in the opening direction by urging means that is a leaf spring (Patent Document 1, page 2, column 4, lines 35-46, FIG. 1).

The said latching means is arrange | positioned in the direction orthogonal to the depth direction of an opening part (3 page 5 column 1-3 lines of patent document 1, FIG. 1).
On the back of the lid door, there is provided an engaging member that pushes to the locking piece of the locking means (page 3, column 5, lines 15 to 17 of Patent Document 1, FIG. 1).
When the lid in the open state is closed, the engaging member pushes the locking piece of the locking means, so that the lid is locked in the closed state.

Thereafter, when the closed lid is pushed in, the engaging member on the back of the lid of the lid pushes the locking piece of the locking means, so that the locked state of the locking means is released, and the lid is a leaf spring. Open by the biasing force of the biasing means.
In addition to Patent Document 1, examples of the locking device for the lid include Japanese Utility Model Publication No. 47-1032, Japanese Patent Publication No. 7-116884, and US Pat. No. 5,836,638. Japanese Utility Model Publication No. 47-1032 has a structure in which the door is pulled when the closed door is opened. Japanese Patent Publication No. 7-116884 and US Pat. No. 5,836,638 have a structure in which the device slides in the depth direction of the opening.

In the conventional lid device described above, the locking means is arranged in a direction orthogonal to the depth direction of the opening, so that the opening is smaller than when the locking means is arranged parallel to the depth direction of the opening. There is an advantage that the depth of the part can be shortened.
However, since the above-described conventional lid device has no action of pushing back the engagement member on the back of the lid of the lid by the locking piece of the locking means when unlocked, the lid is separately biased in the opening direction. Therefore, a biasing means that is a leaf spring is required, and there is a first problem that the structure becomes complicated.

Conversely, the conventional lid device has a second problem that the lid is inadvertently fully opened by the urging means.
Further, since the conventional lid device merely pushes the locking piece of the locking means on the inclined surface of the engaging member on the back of the lid door, the locking means can be unlocked and locked. There is a third problem that the reliability and stability of the operation are low because the device is likely to become unstable and the amount of lock is small.

First, as shown in FIG. 1, in order to close the opened lid 20, the lid 20 may be pushed toward the opening 31 (see FIG. 8).
When the lid 20 is closed, the lock portion 32 on the back surface of the lid 20 comes into contact with the contact portion 93 having a long length at the front end portion of the latch 90 (see FIG. 7).
When the lid 20 is further closed, the latch 90 rotates about the rotation shaft 91 between the case 60 and the slider 70 via the link mechanism 120 against the spring restoring force of the coil spring 80. Retreat inside 60.

At this time, the lock pin 140 located in the introduction path 132 of the cam groove 130 moves relative to the position of the cam groove 130 due to the retreat of the slider 70, so that it proceeds from the introduction path 132 to the forward path 133. .
When the lid 20 is further closed, the slider 70 is further retracted, and although not shown, the lock pin 140 stops at the end of the forward path 133.

When the force to close the lid 20 is released, the slider 70 advances slightly by the spring restoring force of the coil spring 80, and as shown in FIG. 3, the slider 70 advances toward the recessed portion 131b of the heart island 131, The lock device 40 is locked by being fitted in the recess 131b.
