Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge mechanism with a lock mechanism, and more particularly to a hinge mechanism used for opening and closing a door or a panel arranged in a housing structure.

[0002]

2. Description of the Related Art Conventionally, as a hinge mechanism, there is a hinge mechanism used for opening and closing a door or a panel arranged in a housing structure.
Some have a stopper attached to lock these doors and panels in the open state. In particular, a sonar signal processing device mounted on a ship has a casing structure as described above, but doors and panels are attached so that the inside of the casing is not exposed because drip-proof property is required, The lock structure as described above is used for those doors and panels.

As the above-mentioned lock structure, as shown in FIG. 8, a first support member 11 and a second support member 12 are provided.
A hinge pin 13 that connects the first support member 11 and the second support member 12 to each other; a cap nut 17 that is screwed onto the tip of the hinge pin 13; and a spring 18 that biases the cap nut 17 in a predetermined direction (outside). There is one composed of and.

The first support member 11 is shown in FIGS.
As shown in (d), a through hole 11a and a polygonal hole 15 are provided, and the hinge pin 13 has a polygonal part 13a and a screw part 13b as shown in FIG. 9 (a). It is provided.

In the above hinge mechanism, the hinge pin is inserted through the through hole 11a and the polygonal hole 15 of the first supporting member and the through hole 14a and the polygonal hole 16 of the supporting plate 14 of the second supporting member. A cap nut 17 is screwed into a threaded portion 13b at the tip of 13.

Since the cap nut 17 is normally biased outward by the spring 18 arranged between the cap nut 17 and the support plate 14, the polygonal portion 13a of the hinge pin 13 has the polygonal shape of the first support member. Hole 15 and support plate 1 of the second support member
4 and the polygonal holes 16 respectively, and the first support member 1
The first and second support members 12 cannot be opened and closed.

First support member 11 and second support member 12
When opening and closing, and, the hinge pin 13 is pushed from the side of the cap nut 17 against the biasing force of the spring 18, and the polygonal portion 13a of the hinge pin 13 is pushed into the polygonal hole 15 and the second portion of the first supporting member. It is necessary to extrude through the polygonal holes 16 of the supporting plate 14 of each of the supporting members.

First support member 11 and second support member 12
When locking with and open, hinge pin 13
Polygonal part 13a and the polygonal hole 1 of the first support member
5 and the hinge pin 13 is rotated and adjusted so as to fit into the polygonal hole 16 of the support plate 14 of the second support member,
Release the hand from the cap nut 17 to release the pushing.

Regarding the lock structure of this hinge mechanism,
This is described in detail in JP-A-3-005585.

[0010]

In the above-mentioned conventional hinge mechanism, since the polygonal portion of the hinge pin and the polygonal hole of the support member are fitted to each other to lock the opening / closing operation, the door is opened / closed. When the door is used, the door must be opened and closed while unlocking the door, that is, while pushing the cap nut, both when opening and closing the door.

Further, since the polygonal hole provided in the support member has to be a regular polygon, the lock angle of the hinge mechanism can be set only every fixed angle.

Therefore, an object of the present invention is to solve the above problems and to provide a hinge mechanism with a lock mechanism that can be locked so as not to be closed at a constant angle and that can be opened without performing a lock releasing operation. To provide.
