Description

[Detailed Description of the Invention] The present invention relates to an automobile trunk opening assisting device for pushing up the trunk door to a certain extent to facilitate opening of the automobile trunk.

Conventionally, torsion bars, spiral springs, and the like have been installed in the trunks of automobiles to bias the trunk door in the opening direction. However, when a member such as an air spoiler is attached to the top surface of the trunk door, the weight of the member does not balance the load characteristics of the torsion bar or spiral spring, and the torsion bar or spiral spring does not work and locks the trunk door. This caused the inconvenience that it could not be canceled. In this case, it is possible to change the load characteristics of the torsion bar and spiral spring, but if the air spoiler is removed after such changes, there is a risk that the balance characteristics will be disrupted and the trunk door will open suddenly. It was hot.

The present invention eliminates the above-mentioned drawbacks by providing an auxiliary device that works to push the trunk door up within a certain range at the initial stage of opening the trunk. a base member having a collar-shaped stopper screwed onto the lower end of a shaft extending downward from the head; and an opening slidably attached to the shaft of the base member. It is characterized in that it consists of a slider member made of a bottomed cylindrical body with its part facing downward, and an elastic member detachably disposed between the base member and the slider member. Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

In FIG. 5, a trunk room consisting of a trunk body 2 and a trunk door 3 is formed at the rear of the automobile 1. In this trunk room, luggage can be taken in and out by opening the trunk door 3 using a torsion bar, a spiral spring, etc. (not shown), and the trunk door 3 and the trunk body 2 are connected to a hook, etc. A locking mechanism (not shown) is installed to maintain the closed state of the door. In this case, the trunk door 3
It has a double structure of a trunk lid 3a and a trunk lid rain hose 3b, and an air spoiler 4 is attached to the upper surface of the rear end of the upper trunk lid 3a. Therefore, the trunk door 3 may not open due to the weight of the air spoiler 4, and for this reason, a door opening assist device 10 as shown in FIG. 1 is used.

This door opening assisting device 10 consists of a base member 11, a slider member 12, and an elastic member 14 that urges the slider member 12 downward. The slider member 12 is elastically fitted into the drain hose 3b, and is slidably attached to the shaft portion 11b of the base member 11. The slider member 12 is made of a bottomed cylindrical body with an opening facing downward, and its lower end is close to the trunk body 2, so that it comes into contact with the trunk body 2 by sliding. and,
A collar-shaped stopper 13 is screwed into the lower end of the shaft portion 11b of the base member 11, and the slide member 12
The slide amount in the downward direction is regulated within the length of the shaft portion 11b of the base member 11, and the slider member 12 is prevented from coming off. The resilient member 14 pushes down the slider member 12 toward the trunk body. Therefore, in this embodiment, it is made of a coil spring, and the base member 11
It is located between the base member 11 and the slider member 12 in a state in which it is compressedly inserted onto the shaft portion 11b of the slider member 12 . Here, to prevent buckling of the coil spring,
As shown in FIG. 4, the shaft portion 11b of the base member 11 is appropriately formed with a protrusion 15 that contacts the inner diameter portion of the coil spring 14.

Such a door opening assisting device 10 has a base member 11 in a hole in which a rubber damper is attached, for example.
It can be easily attached by fitting the head 11a of the rubber damper, and since it is attached by replacing it with a rubber damper, its removal and attachment are easy. Further, in order to easily fit the rubber damper into the hole, the head portion 11a of the base member 11 is formed into a tapered shape and has a slit 16 as shown in FIG. 2. Further, the lower part of the head 11a is also formed in a tapered shape to absorb the thickness of the trunk lid drain hose 3b and prevent it from wobbling.

In this embodiment as described above, when the trunk door is locked and closed, the slider member 12
is compressed by the trunk body and the trunk door, and the elastic member 14 maintains a compressed state, so the trunk door does not open. On the other hand, when the lock is released, the slider member 12 presses the trunk body due to the action of the resilient member 14, thereby pushing the trunk door upward and opening the door. Since this pressure acts only within the slidable range of the slider member 12, the trunk door does not open suddenly. Moreover, the base member 11
Since a collar-shaped stopper 13 is screwed into the lower end of the holder, by adjusting the vertical position of this stopper 13, the elastic force of the elastic member 14 can be adjusted. Even if the weight of the trunk door changes due to the installation of a spoiler or antenna, the pushing force can be finely adjusted accordingly, ensuring that the resiliency always corresponds to the weight of the trunk door. In this case, the loosening of the stopper 13 is stopped by the frictional force at the screwed portion with the base member 11 due to the elastic force. Furthermore, if the stopper 13 is removed and the engagement between the base member 11 and the slider member 12 is released, the resilient member 14 can be attached or removed. Therefore, large changes in the weight of the trunk door can be avoided by replacing the resilient member 14. You can also respond.

Note that the elastic member is not limited to a coil spring.
Other springs, elastic bodies, etc. may also be used.

According to the present invention described above, the trunk door can be opened even when a heavy member such as an air spoiler is attached to the trunk door, and the trunk door can be opened suddenly even when an air spoiler is not attached. Furthermore, even if the weight of the trunk door changes due to the installation of various air spoilers, etc., by finely adjusting the vertical position of the stopper, the elastic force will be adjusted according to the weight of the trunk door. It has the effect of being convenient and convenient.
