Description

[Detailed Description of the Invention] This invention relates to a stay device for an opening/closing lid of an automobile bonnet or the like.

Conventionally, one end is rotatably connected to the vehicle body via a hinge member, and the other end is opened by lifting the bonnet, etc., between the vehicle body and an opening/closing lid such as a bonnet. As a stay device that locks and supports in position,
For example, the one published in Utility Model Publication No. 39-20102-1 is known.

However, in this structure, when closing the opening/closing lid that is locked in the open position, it is troublesome that the opening/closing lid must be lifted once in the opening direction.

In order to solve the above-mentioned conventional drawbacks, this invention has an extremely simple structure that allows the opening/closing lid to be opened and closed with one-touch operation, and also supports the opening/closing lid securely in the open position and allows for easy opening/closing operation. It is an object of the present invention to provide a stay device for a lid that can be easily opened and closed.

In order to achieve the above object, this invention connects an arm pivotally attached to the vehicle body side and an arm pivotally attached to the lid body side to an intermediate link with a pin, and connects the intermediate link and one arm to the vehicle body. is located on the locking and holding side from the connection line that connects the arm pivot point on the vehicle body side and the lid side when the lid is opened, and the connection pin between the other arm and the intermediate link is located on the opposite side of the connection line and releasing the lock. A stopper is formed on the intermediate link to abut on both arms to maintain the open state when the lid is opened, and a stopper is formed on the intermediate link and the arm on the vehicle body side to open the lid. To provide a stay device for an opening/closing lid characterized in that a spring is stretched to always bias a stopper of an intermediate link toward a vehicle body side arm.

Further, in this invention, the connecting pin between the intermediate link and the vehicle body side arm is movable in an L-shaped groove bored with the end of the vehicle body side arm, and the connecting pin moves in the groove to connect the intermediate link and the body side arm. An opening/closing lid stay device characterized in that the pin is on the locking and holding side from the connecting line, and the connecting pin with the intermediate link of both arms is on the locking and holding side, thereby achieving a safety lock when the lid is opened. It provides:

This invention will be explained in detail below with reference to embodiments shown in the drawings.

One end of the arm 1 is rotatably attached to a bracket 3 via a bin 2, and the bracket 3 is fixed to the inner surface of a lid body 4 made of a bonnet, while one end of the arm 5 is attached to a bracket 7 via a bin 6. The bracket 7 is rotatably fixed to the vehicle body 8.

The other end of the arm 1 is rotatably connected to an intermediate link 9 shaped as shown in FIG. 2 via a connecting pin 10, and an L-shaped pin groove 11 is bored in the other end of the arm 5. , a connecting pin 12 rotatably attached to the intermediate link 9 is slidably fitted into the pin groove 11 to connect the arm 5 and the intermediate link 9.
are connected.

The intermediate link 9 has stoppers 13 and 14 bent in an L-shape in the opposite direction on both upper and lower sides in the figure. 1a, while lower stopper 1
4 is in contact with the side end surface 5a of the vehicle body side arm 5.

Further, a spring 15 is stretched between the intermediate link 9 and the vehicle body side arm 5, and the lid body side arm 1 and the lid body 4 are connected to the intermediate link 9 via the connecting pin 10 by the spring 15 on the opening direction side. It is biased towards.

Connecting pin 1 between the above-mentioned lid side arm 1 and intermediate link 9
0 is located on the lock holding side X on the lid hinge side from the connecting line 1 connecting the pivot pin 2 of the arm 1 and the pivot pin 6 of the arm 5 when the lid body 4 is in the open position, and Unless the pin 10 crosses the line of the connecting line 1, it will be biased by a spring 15 and will not operate in the closing direction.

At this time, the connecting pin 1 between the vehicle body side arm 5 and the intermediate link 9
2 is located on the lock release side Y opposite to the connecting line 1 of the arm pivot pins 2 and 6.

However, when the connecting pin 12 is moved to the right side of the pin groove 11 in the figure from the open state of the lid 4, the connecting pin 12 is also located on the locking holding side X from the connecting line 1, and the lid 4 is opened. It is designed to be safely locked in position.

The opening/closing operation of the stay device having the above structure will be explained with reference to FIGS. 3 to 8.

When the front hinge type lid body 4 is in the closed state, the arms 1 and 5 are folded down with the side connected to the intermediate link 9 facing backward, as shown in FIG.

When the lid 4 is opened from this state, the arms 1 and 5 are opened in the vertical direction, as shown in FIG.

When the arms 1 and 5 are opened until they are in a substantially straight line, the stopper 13 of the intermediate link 9 opens the arm 1 as shown in FIG.
comes into contact with the side end surface of.

The other stopper 14 of the intermediate link 9 is a spring 15
The arm 5 is biased against the side end surface of the arm 5.

In this way, in the open position shown in FIG. 5, the stopper 14 of the intermediate link 9 abuts the arm 5 and the stopper 13 abuts the arm 1, and the rotation of the intermediate link 9 is biased by the spring 15 between the stopper 14 and the arm. At the same time, the stopper 13 of the intermediate link 9 prevents the arm 1 on the lid side from rotating in the closing direction.

At this time, the connecting pin 1 between the lid side arm 1 and the intermediate link 9
0 is the locking holding side X from the connecting line I of arm pivot pins 2 and 6
, and unless the connecting pin 10 moves beyond the point of the connecting line 1 to the locking release side Y, the lid body 4 will not close and operate.
The stay device is locked in the open position shown in the figure, and the lid body 4 is supported in the open position.

Further, if the connecting pin 12 is moved from the open state to the right side of the pin groove 11 in the figure, the connecting pin 12 will be on the locking and holding side X from the connecting line 1 between the arm pivot pins 2 and 6.

As shown in FIG. 6, when the connecting pins 10 and 12 between the arms 1 and 5 and the intermediate link 9 are both located on the locking side X from the connecting line 1, a more reliable safety lock is applied. The lid body 4 is supported in the open position.

When closing the lid 4 from the open state shown in FIG. 5, when the lid 4 is pushed down, the arm 1 rotates downward using the connecting pin 12 as a fulcrum, and the connecting pin rotates downward accordingly. , the connecting pin crosses the point of the connecting line 1, and as shown in FIG. 7, the connecting pin 10.
12 is located on the unlocking side Y from the connecting line 1.

Since the spring 15 urges the intermediate link 9 toward the arm 5 on the vehicle body side, the spring 15 operates in the closing direction and automatically opens the arms 1 and 5 as shown in FIG.
is bent, and the lid body 4 is closed as shown in FIG.

As is clear from the above explanation, according to the opening/closing lid stay device in which two arms related to this invention are bendably connected via an intermediate link, the lid body can be reliably supported in the open position, and the lid can be simply opened. It can be opened and closed with just one touch, just by opening and closing the body.

Furthermore, a safety lock can be applied to ensure safety when opening/closing the lid.

Further, this device has the advantage of having a simple structure, a small number of parts, and being able to be provided at low cost.
