Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to the structure of a catch portion of a luggage door device used in vehicles such as automobiles.

[Prior art]

Generally, the catch part of an automobile luggage door device is fixed to the rear end of the luggage door, and this has the disadvantage that the catch part gets in the way of workers when opening the luggage door to take in and take out luggage.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a luggage door device which has a simple structure and whose catch portion can be rotated upward when the luggage door is opened.

[Concept of the invention] The feature of the invention is that a catch part is provided at the tip of the luggage door so as to be rotatable via a rotary shaft, and a guide member is fixed to the inner surface of the luggage door. The other end is a rigid wire fixed to an arbitrary point on the body above the bisector of the rotation angle when the luggage door is fully opened.

[Example of idea]

Embodiments of the present invention will be described based on the drawings. 1 and 2 show the configuration of an embodiment of the luggage door device according to the present invention. In these figures, 1 is a luggage door attached to be openable and closable by a door hinge 4, and the front end of the luggage door 1 is A catch section 2 is provided at the section via a rotating shaft 8.

Furthermore, an outer wire 5 formed into a tubular shape is fixed to the inner surface of the catch portion 2 at several locations by clamps 7.

Then, an inner wire 6 made of a rigid material such as stainless steel is inserted through the outer wire 5, and one end of the inner wire 6 is connected to an arbitrary point of the catch part 2, for example, point Q, and the other end is connected to the rotation angle when the luggage door 1 is fully opened. It is fixed at an arbitrary point on the body above the bisector of , for example, point D.

The outer wire 5 restrains the movement of the inner wire 6 when the luggage door is opened and closed, and functions as a guide member.

In the above configuration, when the luggage door is opened or closed, the catch portion 2 and the inner wire 6 cause relative displacement because their respective rotation trajectories are different.

Utilizing this relative displacement, the inner wire 6 pushes up the catch part 2 when the luggage door is opened, thereby rotating the catch part 2 upward.

This principle will be explained with reference to FIG.

In the figure, A is the end of the luggage door 1, and B is the end of the luggage door 1.
is the center of the door hinge 4, D is the fixed point of the inner wire 6 on the body, O is the position of the rotating shaft, Q is the fixed point of the inner wire 6 in the catch part 2, P is the position of the tip of the door catch part, and the solid line is The one-dot chain line shows the state of the inner wire 6 when the luggage door 1 is closed, and the one-dot chain line shows the state when the luggage door 1 is open.

In the figure, if the length of the inner wire 6 when the luggage door is closed is ls, then ls=++ (1), and this length does not change even when the luggage door 1 is open.

On the other hand, if lo = ′+′′+′′ when the luggage door 1 is opened/closed, then when the door 1 is opened, ls−lo=−′(=
The inner wire 6 is pulled out from the outer wire 5 by Δl).

As a result, the inner wire 6 connects the catch portion 2 with Q
This acts to push up the catch portion 2 at the point, causing the catch portion 2 to rotate upward.

[Effect of idea]

According to the present invention, the structure is simple and the catch portion can be rotated when the luggage door is opened, thereby ensuring the safety of the worker.
