[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION In the present invention, a relatively thin display such as a liquid crystal is pivotally supported by a main body such as a word processor provided with a keyboard or the like so as to be suitable for carrying, and is opened and closed. In addition, the present invention relates to a tilt mechanism in a small electronic device that can be stopped in a tilt state so that a display can be easily viewed.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, for example, as shown in FIG. 4, a tilt mechanism in a small electronic device of this kind is provided with a keyboard or the like of a personal computer on a display body 1 having a thin display surface such as a liquid crystal. Projections 1a are formed on both left and right sides of a position close to both ends of the main body 2 side.

[0003] Opposite to the projection 1a, this projection 1a
Is formed in the main body 2, and the outer surface of the projection 1a and the depression 2 facing the outer surface of the projection 1a.
The shaft 3 is rotatably inserted through the insertion holes 1b and 2b on the inner surface of the a, and the protruding portion 1b of the shaft 3 is fixed to the display body 1 in the protruding portion 1b. It is fixed to the tool 4 so that it cannot rotate.

On the shaft 3, a coil spring 5 wound on the main body 2 side with a smaller diameter than the outer diameter of the shaft 3 and having opposite winding directions on the left and right sides is inserted in a press-contact state. The hooks at both ends are provided on the main body 2 that bears the shaft 3 so that the shaft 3 does not rotate even when the shaft 3 is rotated.
The main body 2 is inserted into a support 6 fixed inside the main body 2.
And the display body 1 are electrically connected by a cable 7.

Therefore, when the display body 1 is to be opened and closed with respect to the main body 2, the shaft 3 also rotates with the opening and closing of the display body 1. At this time, the tightening force of the coil spring 5 on the shaft 3 acts as a brake. Act,
It becomes a load for the opening and closing. Therefore, when the external force for opening and closing is released, the display body 1 is prevented from falling down by the brake, and the tilt state is maintained.

A shaft is rotatably mounted on a main body of a personal computer or the like, and is rotatably mounted substantially at the center of the display body. A configuration is disclosed in which a hook portion includes a plurality of coil springs supported by the main body and having mutually opposite winding directions.

[0007]

In such a tilting mechanism for a small electronic device, a coil spring is provided at both ends of a shaft in a press-contact state, and both ends of the coil spring are fixed to a main body. Alternatively, it is fixed by providing members for fixing both ends of the coil spring. Therefore, the assembling work is complicated, the number of parts is large, and the cost is high.

The present invention solves the above-mentioned problem of the tilt mechanism in the conventional small electronic equipment. The assembly work can be easily performed by attaching the shaft and the coil spring to the support to form one unit. Accordingly, it is an object of the present invention to provide a tilt mechanism in a small electronic device capable of reducing the number of parts and assembling in a previous process.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a shaft which is rotatably mounted on a main body of a personal computer or the like, and which is rotatably mounted substantially at the center of a display body. A tilt mechanism in a small electronic device, comprising a plurality of coil springs whose coil portions are externally inserted into the shaft in a press-contact state and whose both end hook portions are supported by the main body, the coil springs having opposite winding directions. The spring is mounted on one support.

[0010]

[Function] The tilt mechanism in the small electronic device of the present invention is as follows.
The shaft with the coil spring extrapolated to the support in a press-contact state and both ends of the coil spring are fixed to form a single unit, so that the assembly work can be performed easily and the number of parts can be reduced. Can be assembled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, an example in which the present invention is applied to a tilt display device for a personal computer will be described. However, the present invention is not limited to this and can be widely applied to a tilt mechanism in a small electronic device such as a word processor. In the center of the back side of the main body 2 provided with a keyboard, etc.,
The display body 1 provided with the projection 11 and a display such as a liquid crystal is attached to the display body 1.
Is provided with a concave portion 12 which fits into the recess.

In the left and right surfaces 12a of the recess 12, through holes 12b through which a shaft 13 for supporting the main body 2 and the display body 1 are inserted are drilled, and left and right of the projecting portion 11 facing the surface 12a. The side surface 11a is formed with an introduction groove 11b through which the shaft 13 can be introduced from below.

As shown in FIG. 2, a shaft 13 and coil springs 16, 16 can be prepared on a support 15 in advance. Both ends of the shaft 13 are formed as oval portions 13a. The left and right mounting members 14 into which the oval portions 13a are inserted are fixed in the display body 1, and the shaft 13 is mounted in the main body 2. The support member 15 is supported by the left and right cut-and-raised pieces 15a and wound between the left and right cut-and-raised pieces 15a in opposite directions to each other.
Two coil springs 1 wound to a diameter smaller than the outer diameter of the coil spring 1
6 is externally inserted into the shaft 13 in a press-fitted state.

The hooks at both ends of the two coil springs 16 are supported by a support 15 so that when the shaft 13 rotates, the friction between the coil spring 16 and the shaft 13 causes the rotation resistance of the shaft 13 to rotate. However, one of the coil springs 16 acts as a tightening side and the other acts as a slack side for forward and reverse rotation of the shaft 13.

By the action of the coil spring 16, a resistance is generated when the display unit 1 is opened and closed, so that the display unit 1 is not opened and closed unnecessarily and the display unit 1 can be maintained in a tilted state. . In addition, when the display body 1 is opened and closed, the place where the resistance occurs is located at the center of the display body 1, so that an unbalanced load is not applied to the display body 1 and the display body 1 has a very small tendency to curve. Become.

As a result, the distortion applied to the liquid crystal provided on the display body 1 is reduced, so that there is no possibility that the liquid crystal is damaged, and the display body 1 can be opened and closed smoothly.

Further, while two shafts 3 are conventionally used, only one shaft 13 is sufficient and the length thereof can be shortened. Therefore, the space occupied by these shafts is smaller than that of the conventional one, and the space can be saved. The number of parts and the number of assembling steps can be reduced because two supports 6 are sufficient with one support 15.

[0018]

As described above, in the present invention, the shaft for supporting the display body on which the display is provided so as to be openable and closable has been conventionally provided on the left and right sides of the display body. By providing one unit, the number of parts can be reduced and the number of assembly steps can be reduced, which can contribute to cost reduction. In addition, since the shaft and the coil spring are attached to the support to form a single unit, the unit can be easily attached to the main body or the like, and can be prepared in the previous process, and can be assembled in the present process. Work can be done easily.
