DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure.

[0002]

2. Description of the Related Art A conventional hinge structure will be described.

FIG. 5 is a perspective view of a conventional hinge structure.
FIG. 6 shows a cross section of a hinge structure attached to a floor member and a lid body.

In the figure, a hinge structure a comprises a fixed hinge b attached to a floor member e by bolts or the like, and an opening / closing hinge c attached to a lid body f by bolts or the like.
Are connected to each other by a pin d at an intermediate portion thereof, so that the lid body f is rotated to put in and out the stored items.

[0005]

However, in the above-mentioned conventional hinge structure a, there is no lock mechanism for locking the rotation of the opening / closing hinge c, so that the lid body f cannot be stopped during opening / closing. Since the lid body f must be held by hand, there is a problem that it takes time to take in and out the stored items.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a hinge structure which can be locked at an intermediate position between opening and closing.

[0007]

In order to achieve the above object, a hinge structure according to the present invention comprises a loop portion provided on one hinge member, and a pin provided on the other hinge member is inserted through the loop portion so as to be vertically movable. The other hinge member has a configuration in which a contact surface that abuts on a loop portion of one hinge member when the hinge member rotates to limit the rotation of the other hinge member is provided.

[0008]

According to this structure, when the other hinge member is rotated while the pin is moved downward, the contact surface of this hinge member comes into contact with the loop portion of one hinge member and the rotation of the other hinge member is stopped. Because of the restriction, the other hinge member can be locked at the intermediate position between the open and closed positions.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a luggage room having a hinge structure according to the present invention, FIG. 2 is a perspective view of the hinge structure, and FIG. 3 is an exploded perspective view of the hinge structure.

In FIG. 1, reference numeral 10 denotes a hinge structure, 1 denotes a fixed hinge which is one hinge member, and 4 denotes an opening / closing hinge which is the other hinge member.

A partition plate 13 is provided on a floor member 12 of the luggage room 11, and a front edge of the partition plate 13 is connected to the floor member 12 via a hinge structure 10, and a rear end of the partition plate 13 is provided. By flipping up the portion 14 in the direction of the arrow, a storage space 15 for small articles is secured behind the partition plate 13.

The hinge structure 10 includes a fixed hinge 1 fixed to the floor member 12, an opening / closing hinge 4 fixed to the front end of the partition plate 13, and a pin 8 connecting the fixed hinge 1 and the opening / closing hinge 4. It consists of

A loop portion 3 having a loop 2 is formed at the center of the fixed hinge 1, and a stopper portion 6 having a contact surface 5 is formed at a position corresponding to the loop portion 3 of the opening / closing hinge 4. I have. Further, bearing portions 7 for gripping pins 8 are formed at both ends of the opening / closing hinge 4, and the fixed hinge 1 and the opening / closing hinge 4 are connected by gripping the pins 8 inserted into the loop portion 3. ing.

The pin 8 can be moved up and down in the loop 2, and the contact surface 5 of the stopper portion 6 is set so as to contact the side surface 9 of the loop portion 3 when the opening / closing hinge 4 rotates 90 °. ing.

The hinge structure 10 constructed as described above
4A, the pin 8 of the opening / closing hinge 4 is located above the loop 2 in the state before the rotation in FIG.
Is in a horizontal state. Next, when the opening / closing hinge 4 is rotated in the direction of the arrow in FIG.
The contact surface 5 is inclined while moving down inside. When the opening / closing hinge 4 is further rotated in the direction of the arrow, as shown in FIG. 4 (c), the pin 8 moves down in the loop 2, and the contact surface 5 contacts the side surface 9 of the loop portion 3 of the fixed hinge 1. The rotation of the open / close hinge 4 is limited by the contact. When the hinge 4 is returned to the position shown in FIG. 4D from this state and the hand is released, both hands can be used freely.

The hinge 4 is lifted upward to move the pin 8 upward in the loop 2 while the hinge 4 is moved upward.
Is pivoted in the opening direction, the opening / closing hinge 4 can be fully opened. Further, by performing the operation opposite to the above, the opening / closing hinge 4 can be returned to the original state.

Therefore, since the opening / closing hinge 4 can be locked at the intermediate position between the opening and closing, the opening / closing hinge 4 can be locked.
There is no need to manually hold the partition plate 13 to which is attached, and small articles can be easily taken in and out while the opening / closing hinge 4 is locked. Further, by locking the opening / closing hinge 4 at the intermediate position, a storage space for small items can be secured, and there is also an effect of suppressing movement of objects during traveling.

[0019]

As described above, according to the present invention, the pin provided on the other hinge member is inserted into the loop portion provided on one hinge member so as to be movable up and down, and the other hinge member is
By providing a contact surface that contacts the loop portion of one hinge member during rotation of the hinge member and restricts rotation of the other hinge member, the other hinge member is rotated while the pin is moved downward. Then, the contact surface of the hinge member abuts on the loop portion of one hinge member to limit the rotation of the other hinge member, so that the other hinge member can be locked at the intermediate position between opening and closing.
