Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luggage opening / closing device for a vehicle such as a passenger car.

[0002]

2. Description of the Related Art In a vehicle of this type, for example, FIG.
As shown in FIG. 1, the luggage door 1 is opened and closed by rotating a hinge arm 2 connected thereto around a support shaft. The hinge arm 2 is urged by the torsion bar 3 in the opening direction of the luggage door 1 as shown in FIG. Thereby, when the luggage door 1 is opened, the luggage door 3 stops at an appropriate degree of opening due to the reaction force of the elasticity of the torsion bar 3.

[0003] The torsion bar 3 includes a reaction force adjusting type and a reaction force fixing type. As shown in FIG. 6, the reaction force adjusting type has a plurality of mounting holes 4 at which the tip of the torsion bar 3 is hooked, and a reaction force corresponding to the mounting holes 4 can be obtained. Such a reaction force adjusting type torsion bar 3 is generally used to cope with an increase in mass (weight) when an option is mounted, or used for static adjustment of reaction force.

[0004]

As described above, in the case of using the reaction force adjusting type torsion bar 3 as described above, it is necessary to select a desired mounting hole 4 and lock the tip of the torsion bar 3 on it. Was troublesome. In addition, it is not always easy to always keep the luggage door 1 at an appropriate opening degree under all conditions when the luggage door 1 is opened.

[0005] In view of the above, it is an object of the present invention to provide a luggage opening / closing device which can always maintain an appropriate opening when a luggage door is opened.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a luggage door is opened and closed by rotating a hinge arm connected to the luggage door around a support shaft. A latch mechanism for locking and holding the luggage door at an arbitrary opening, a lock release mechanism for releasing the lock on the luggage door by the latch mechanism, and a state in which the unlocked latch mechanism can be operated. And a reset mechanism for returning to the normal state. In the invention described in claim 2, the latch mechanism includes a latch that rotates integrally with the hinge arm around the support shaft, and a hook that is disposed near the support shaft so as to engage with the latch. And According to the third aspect of the present invention, the unlocking mechanism includes a cable connected to the tip of the hook, an unlocking handle for driving the hook to rotate via the cable, and a rotational driving position for engaging with the hook and engaging the hook. And a cam to be held. In the invention described in claim 4, the reset mechanism includes a link connecting the latch and the cam, and disengages the hook and the cam when the luggage door is closed. I do.

According to the present invention, when the luggage door is opened, the luggage door can be locked and held at an arbitrary opening by the latch mechanism. Further, by operating the lock release handle of the lock release mechanism, the lock on the luggage door can be released, and when the luggage door is closed, it can be returned to the initial state by the reset mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, members that are substantially the same as or correspond to those of the prior art will be denoted by the same reference numerals.
A preferred embodiment of the luggage opening / closing device according to the present invention will be described. FIG. 1 shows a configuration of a main part in this embodiment. The luggage door 1 is opened and closed by rotating the hinge arm 2 around a support shaft. The hinge arm 2 is urged by the torsion bar 3 through the link 5 in the opening direction of the luggage door 1. The torsion bar 3 is mounted on a support 6 fixed to the body.

An apparatus according to the present invention includes a luggage door 1.
A latch mechanism for locking and holding the latch at an arbitrary opening, an unlock mechanism for unlocking the luggage door 1 by the latch mechanism, and a reset mechanism for returning the unlocked latch mechanism to a lockable state. It is composed.

The latch mechanism includes a latch 8 which rotates integrally with the hinge arm 2 around the support shaft 7, and a hook 9 arranged near the support shaft 7 so as to engage with the latch 8. The hook 9 is rotatably supported around a pin 10 implanted in the support 6, and the spring 11
The hook 9 is urged in the direction of engagement with the latch 8.

The lock release mechanism engages with the cable 12 connected to the distal end of the hook 9, a lock release handle 13 (see FIG. 2) for rotating the hook 9 via the cable 12, and the hook 9. And a cam 14 held at the rotational drive position. The cam 14 is rotatably supported around a pin 15 implanted in the support 6, and a spring 16 urges the cam 14 in the direction of engagement with the hook 9.

The reset mechanism includes a link 17 connecting the latch 8 and the cam 14. A pin 18 implanted in the cam 14 is slidably fitted in the long hole 17a of the link 17. The reset mechanism releases the engagement of the hook 9 and the cam 14 when the luggage door 1 is closed.

The luggage opening / closing device of the present invention is constructed as described above, and its operation will be described below. FIG.
Shows the outline of the operation of the device of the present invention. FIG. 3 (A)
As the luggage door 1 opens (arrow A), the latch 8 rotates together with the hinge arm 2. The hook 9 moves along the engagement portion of the latch 8, and when the latch 8 stops, the two are always in the engaged state. Therefore, the reverse rotation of the latch 8, that is, the closing of the luggage door 1 is restricted, and the latch 8 can be locked and held at an arbitrary opening. The operation in the opening direction of the luggage door 1 is possible.

In FIG. 3B, when closing the luggage door 1, when the lock release handle 13 is pulled (arrow B), the hook 9 rotates against the elasticity of the spring 11 and comes off the latch 8. At the same time, hook 9
The latch 8, that is, the luggage door 1 can be freely opened and closed by the engagement of the cam 14 with the cam 14. In this manner, the luggage door 1 can be unlocked at an arbitrary opening by operating the unlock handle 13.

In FIG. 3C, when the luggage door 1 is closed from the state shown in FIG.
Slide up and push pin 18 at the end of its slot 17a. The engagement between the hook 9 and the cam 14 is released, and the cam 1
4 returns to the initial state. As a result, the latch mechanism is reset, and the luggage door 1 can be locked and held again at an arbitrary opening.

As is apparent from the above description, when the luggage door 1 is opened and closed, it is possible to reliably prevent the luggage door 1 from dropping halfway due to disturbance factors such as the vehicle attitude when stopped and wind. This state can be maintained by locking at an arbitrary opening degree as shown in A). In addition, since locking can be performed at an arbitrary intermediate opening degree, the luggage door 1 can be reliably held in the fall area shown in FIG. 4B.

The luggage door 1 can be operated in the opening direction from the intermediate opening position, and can be operated in the closing direction after the lock is released by operating the lock release handle 13. If the luggage door 1 has a sufficient holding force when fully opened, there is no need to balance the torsion bar 3 in the middle range, so fine tuning is not required.
This makes it possible to eliminate the conventional construction of the torsion bar 3. Furthermore, even if the mass of the luggage door 1 is increased due to a retrofit component such as a light license, it is possible to effectively cope with the increase and always obtain a proper operation.

[0018]

As described above, according to the present invention,
In this type of luggage opening and closing mechanism, when the luggage door is opened, the luggage door can be locked and held at an arbitrary opening by the latch mechanism, and the lock on the luggage door can be released by operating the lock release handle. Usability can be realized.
Particularly, by preventing the luggage from dropping at an intermediate opening, there is an advantage that high safety is ensured.
