Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door opening device with an automatic hinge fixing device.

Although most swing doors are generally mounted on a vertical surface, there are also swing doors that are mounted on an inclined surface, for example in the front of a vehicle, as shown in FIG. When a door attached to an inclined surface is opened inward in this way, the center of the hinge can be placed inside the vehicle body, so the door opening device can be easily constructed. However, when opening outward, the normally used single-axis flat hinge cannot be configured unless the hinge 2 is along the slope as shown in Figures 2 and 3, so the door 1 can be opened horizontally. If you cannot open the door and it opens, you will need to push the opening door 1 up from a certain point.
Furthermore, it is extremely difficult to operate since it may open spontaneously from a certain point due to its own weight. Furthermore, if you want to open the door horizontally, it is impossible with a normal flat hinge, so in order to make it possible to open and close with a single-axis hinge, you need a structure where the center of the hinge is provided outside the vehicle body, or Alternatively, it is necessary to use a very large hinge as a hidden hinge, which is difficult in terms of vehicle construction.

In order to solve the above-mentioned problems, the present invention aims to horizontally and easily open a door attached to an inclined surface, and for this purpose, the hinge axes are provided vertically, and each hinge has two axes. Double hinged,
The hinge is a hidden hinge that cannot be seen from the outside when the door is open and closed, and a hinge fixing device is provided to automatically fix one shaft of the double hinge.

Hereinafter, the present invention will be described with reference to FIGS. 4 to 11, focusing on a structure in which the door mounting surface is inclined in a dogleg shape as shown in FIGS. 2 and 3. Fig. 4 is a plan view showing an embodiment of the door opening device of the present invention, Fig. 5 is a plan view showing details of the main parts of Fig. 4 with the door closed, and Fig. 6 is a plan view showing the door opening device. Fig. 7 is a detailed view of the main parts with the door pushed out, Fig. 8 is a BB view of Fig. 5 (links are shown in a long view), Figure 9 is a CC view of Figure 6, and Figure 10.
The figure is a sectional view taken along the line DD in FIG. 8, and FIG. 11 is a sectional view taken along the line EE in FIG.

As shown in FIGS. 4 and 5, the hinges 4 and 5 are double hinges having two axes, a shaft 4a and a shaft 5a, respectively. The hinges 4 and 5 are connected, for example, by a pivot hinge system in which the hinge 5 has a shaft and the hinge 4 has a hole. Connect hinge 4 to body 1
It is fixed to the hinge receiver 6 on the 4 side with a machine screw, and the hinge 5 is fixed to the swing door 3 with a machine screw. As shown in FIGS. 5 and 8, the hinge fixing device includes a link 7 having an elongated hole 7b, a link receiver 5b, a shaft 8, a spring 9, and a knob 1.
0, and mandrel supports 11 and 12. The lower end of the mandrel 8 has a stopper shaft 8a, and the link 7 has a stopper hole 7a. The link receiver 5b has an integral structure with the movable part of the hinge 4,
It is connected to the link 7 by a pin 13, so that the link 7 can freely rotate. Mandrel bridge 11,1
2 is fixed to the hinge receiver 6 on the vehicle body 14 side with a small screw. Thus, the axes 4a of the upper and lower hinges are aligned in the vertical direction.

When the door 3 is closed, the mandrel 8 is located at the elongated hole 7b of the link 7, as shown in FIGS. FIG. 6 shows a state in which the swing door 3 is pushed outward, and from the state shown in FIG.
During the rotation, the swing door 3 rotates around the shaft 5a and enters the state shown in FIG. When the hinge 4 rotates, the link receiver 5b moves and the link 7 moves, and the stopper hole 7a of the link 7 moves as shown in FIG.
moves to the position of the mandrel 8 and becomes the state shown in FIGS. 9 and 11, the stopper shaft 8a of the mandrel 8 matches the stopper hole 7a of the link 7, and the spring 9 causes the stopper shaft 8a to move into the stopper hole 7a. The link 7 and the hinge 7 are fixed to the axle receiver 11. Once the hinge 4 is fixed, the door 3 can be opened without hitting the vehicle body 14 even though the hinge is hidden by rotating the door 3 around the shaft 5a, resulting in the state shown in FIG. 7. become. In this case, since the positions of the hinge axes are aligned vertically, the door 3 is opened horizontally.

The operation when closing the door 3 will be explained with reference to FIG.
When the knob 10 is pushed down against the spring 9, the stopper shaft 8a of the mandrel 8 is disengaged from the stopper hole 7a of the link 7, and the link 7 becomes free to move. The door 3 can be closed, resulting in the state shown in FIG.

Since the present invention is as described above, it has the effect that a door attached to an inclined surface can be horizontally and easily opened outward.
