JPH0751387Y2 - Open support device for rear door of automobile - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for supporting a rear door such as a commercial vehicle, a three-door vehicle and a five-door passenger car and a rear door such as a trunk room, and adjusting the degree of opening. It is a thing.

[Conventional technology]

The rear door of a conventional automobile has a structure in which an automatic opening means such as a cylinder and a spring is provided, and the lock is unlocked so that the door is fully opened all at once.

[Problems to be Solved by the Invention] The rear door of a conventional vehicle cannot be fully opened by the automatic opening means even when a small amount of luggage is loaded, and the degree of opening cannot be adjusted. .

Therefore, if you put your luggage in or out during rainy weather, the rain will enter the inside of the car each time and the inside will get wet, or if you open the rear door in a garage with a low ceiling, the rear door will hit the ceiling and damage the rear door and buildings. Things often happen.

Further, when the luggage in the trunk is too large to close the door, there is an inconvenience that it must be restrained with a string or the like against the automatic opening force.

In order to solve the above problems, the present invention provides a device capable of adjusting the opening degree of a rear door.

[Means for Solving the Problems]

In order to achieve the above object, the present invention has a rotating shaft at the base of a rear door of an automobile, and is capable of passively rotating around the rotating shaft as a fulcrum, and the opening angle of the rear door at the rotating shaft. It is characterized in that a support means for locking the above is provided in several stages.

[Action]

To describe the operation of the present invention, the rear door has a rotation shaft at the base, and can freely rotate about the shaft as a fulcrum.

However, since the automatic opening means is not attached to open the rear door, the rear door does not rotate upward even if the lock is released.
Therefore, the rear door is pushed up manually, but since the pivot shaft has the supporting means for locking the rear door, the user manually rotates it up to an arbitrary angle to lock and open it.

Then, after use, the lock is released and pushed down to close the lock.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

(1) (1) is a bearing bracket fixed to both sides in the trunk of the vehicle body, two substantially fan-shaped plate bodies are provided to face each other, and concave portions (3) (3) are provided in each arcuate end face (2). (3) is formed.

Reference numeral (4) is a trunk door, and the shaft (6) is provided over the brackets (5) and (5) provided on both sides of the base, and at the same time, the arcuate end surface (2) of the bearing brackets (1) and (1). The door (4) is rotatably supported by the vehicle body by being inserted in the center of the vehicle.

(7) is a locking rod, bearing bracket (1)
A spring which is inserted into the long holes (8) and (8) provided in the brackets (5) and (5) in parallel with the centripetal line of the arcuate end faces (2) and (2) of (1) and stretched between the shafts (6). (9) (9) is urged to press the arcuate end faces (2) (2).

Therefore, the rotation of the door (4) causes the locking rod (7).
Is the arcuate end face (2) (2) of the bearing bracket (1) (1)
It comes into contact with and slides.

However, recesses (3) and (3) are formed in the arcuate end faces (2) and (2).
(3) is formed, and this recess (3) is slidable in the upward direction, but has a locking shape in the downward direction. Therefore, if the positive opening of the door (4) is stopped, the spring is opened. (9)
The locking rod (7) is locked in the recess (3) by being biased by (9), and the door (4) is supported to maintain its open portion.

A release piece (10) is loosely fitted to the shaft (6), and the tip of the release piece (10) has an arcuate end surface (2) of the bearing bracket (1).
(2) The upper and lower stoppers (12a) (12) are curved surfaces having a top (11) slightly protruding from the bearing bracket (1) (1) and are located above the locking rod (7).
b) It is possible to rotate between.

When the door is opened, the release piece (10) is pushed by the locking rod (7) to be rotated or supported, but when it hits the upper stopper (12a), it cannot be further rotated, and the pushed locking piece is pushed. When the rod (7) further rotates upward (opens), it rides on the top (11) of the release piece (10).

When the door is closed (rotated downward) in this state, the locking rod (7) is strongly urged to the top (11) by the springs (9) and (9), so that the release piece (10) is accompanied. And the top part (11) of the release piece (10) projects from the arcuate end face (2), so that the top part (11) is rotated downward without being affected by the concave part (3) and the door can be closed and rotated. If you rotate it further downward, the release piece (10) will
Upon hitting b), further downward rotation is prevented, only the locking rod (7) rotates, the locking with the top part (11) is released, and it comes into contact with the arcuate end faces (2) (2). Therefore, the upper stopper (12a) is positioned above the uppermost recess (3a) of the locking rod (7) so as to lock the top portion (11) and the locking rod (7), and the lower stopper (12a). (12b)
Is positioned below the lowermost recess (3b) of the locking rod (7) and before the door is closed, each recess (3) of the door (4) and the locking rod (7) can be positioned. Opening support and closing at the locking angle can be performed.

[Effect of device]

As described above, according to the present invention, since the opening of the rear door can be manually operated and supported at an arbitrary angle, it can be opened according to the surrounding conditions and the necessity of opening, as compared with the conventional automatic maximum opening mechanism. Therefore, it has the effect of preventing unexpected obstacles and unnecessary opening.

Further, since the supporting device is provided on the rotary shaft, the mechanism can be added without much difference from the conventional one, and there is no trouble in appearance and in use.

Further, the structure of the present invention is naturally included in the case where the trunk room is located in the front part of the vehicle body, and can be diverted to the door of the engine room.
