JP2000297574A - Hinge with click and friction function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To keep a specified position of a display without the provision of an additional rotation restricting mechanism through engagement between a recess and a protrusion made by clicking by providing the recess and protrusion on both movable side fixed plate and main body side fixed plate of a hinge, and pressing the same with a spring. SOLUTION: In a hinge to keep a display of a note-type personal computer, video camera or the like turnable, a thick wall waved spring 3 and a thin wall waved spring 4 are arranged in series through a flat washer 5 so that a movable side fixing plate 1 is pressed against a main body side fixing plate 2. When the display is opened, a projection 1a of the fixed plate 1 frictionally slides on the flat part 2b of the fixed plate 2 by being pressed by the springs 3, 4 to thereby keep the display at an arbitral position. When the display is closed, the protrusion 1a of the plate 1 and a recess 2a of the plate 2 are clickwise actuated to be fitted each other to thereby allowing the protrusion 1a to aubt on a side inclination part of the recess 2a for keeping the display in a closed consition. Accordingly, the purpose is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

This hinge is used for opening and closing a display device of a notebook personal computer, a liquid crystal display device of a video camera, a lid and a door of an electric pot and an electric pot, and the like.

[0002]

2. Description of the Related Art For example, in a display device of a notebook personal computer,
Hinges were used that only applied friction using only heavy springs.

[0003]

In the case where a hinge that merely applies friction is used, a slight gap is left even when the display device is closed, so that a separate hooking function is provided to ensure that the display device is closed. However, in this case, it is necessary to remove the hook once and then open it, which is troublesome.

[0004]

According to the present invention, a spring with a large load for applying friction and a spring with a small load acting only when closed but large deflection can be arranged in series.
The movable-side fixed plate and the main-body-side fixed plate pressed by the spring were provided with convex portions and concave portions each having an inclined portion on the side surface.

[0005]

According to the structure described above, since a rotational force in the closing direction is applied to the inclined portions on the side surfaces of the convex portions and the concave portions, no gap is formed when closed, and it is not necessary to provide a special hook. At the same time, when you open it, you only have to pull it, so you don't have to worry about it.

[0006]

1 shows an entire hinge, and FIG. 2 shows an exploded view. The movable side fixed plate 1 is provided with a convex portion 1a (convex on the back side), and when closed, it is located at a position that matches the concave portion 2a of the main body side fixed plate 2. Further, the thick plate spring 3 and the thin plate spring 4 apply pressure to the movable-side fixed plate 1 with a simple flat washer 5 interposed therebetween, and the gap between the movable-side fixed plate 1 and the main-body fixed plate 2 is increased. Is configured to generate a frictional force.
Therefore, when the movable-side fixed plate 1 is open, the protrusion 1a
Is opposed to the flat portion 2b of the main body side fixing plate 2, the thin plate spring 4 is largely bent, and the thick plate spring is thick.
The spring 3 is deflected by applying a pressure corresponding to a necessary frictional force. When the movable-side fixed plate 1 approaches the closing position, the convex portion 1a is opposed to the side inclined portion 2c of the concave portion 2a, and the wave spring 4 having a small thickness acts greatly, so that the movable-side fixed plate 1 moves in the closing direction. Since it is moved and clicked, there is no gap at the closed position. FIG. 3 shows an example in which a similar function is applied to a hinge of a liquid crystal display device of a video camera. The opening and closing plate 11 for opening and closing the liquid crystal display device is provided with a friction and click function, and the rotation of the liquid crystal display device is controlled. In addition, the friction and click functions are provided by the rotating plate 12.
In order to protect a harness connecting the liquid crystal display device and the main body, the cam 13 is provided between the main body fixing plate 14 and the opening / closing plate 11 and the rotating plate so that the liquid crystal display device is not opened and closed at an angle of 90 °. It is to prevent the movement of 12.

[0007]

According to the above construction, only a spring capable of obtaining a large deflection and a spring capable of obtaining a large load are arranged in series, so that only a small space is required. By providing a concave portion on the opposed plate and providing a click function at the side inclined portion of each concave / convex portion, there is no gap at the closed position and there is an advantage that a separate closing mechanism is not required. .
