[0002]

2. Description of the Related Art In a portable information terminal device having a display section on a top surface, a protective cover can be opened and closed on the main body of the apparatus in order to prevent the display section from being destroyed due to collision with another object in a bag. Some are attached to. In recent years, the protective cover has a double-twin mechanism provided with two fork portions for attaching the protective cover so that the protective cover can be rotated to the bottom surface of the device main body, so that it does not interfere with use at all. You can do so.

FIG. 6 is a schematic side view of an information device employing this conventional display section protection cover mechanism. Conventionally, as a display section protection cover mechanism, a fixed stub 3 for pivotally supporting the protection cover 1 substantially at the center of the rear surface of the device body 2;
When the display cover of the protective cover 1 is provided, the movable cover 4 is provided at a position just in contact with the edge of the upper surface of the apparatus main body, and the movable cover 4 is attached to the protective cover 1 so as to be rotatable. You can do as follows.

[0004]

However, since the fixed tongue is mounted in a rotatable state,
When the display unit is covered with the protective cover, the angle of the fixed tongue cannot be adjusted. Therefore, as shown in FIG. 7, the protective cover is made to swing in the vertical (arrow A) direction.

[0005] Further, the clearance between the shaft of the fork part and the shaft hole causes the protective cover to be slightly hit in the lateral direction.

[0011]

Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 1 is a schematic perspective view of an information terminal device employing a display unit protection cover mechanism according to a first embodiment of the present invention. Information terminal equipment body 11
A display unit 12 is provided on the upper surface of the device, and a protective lid 13 is attached to the device main body 11 so as to cover the display unit 12. When the protective lid 13 is closed and covers the display unit 12 (hereinafter, referred to as “closed”), the protective lid 13 is locked by the latch 14. Further, the protection lid 13 is attached to the device main body 11 so as to be freely opened and closed by a hinge mechanism having the following structure. The basic structure is the same as the conventional one.

FIGS. 2 and 3 are views showing the double-branch structure when the information terminal device is viewed from the direction of arrow B in FIG. 1. FIG. 2 shows a state in which the protection lid 13 is open. When,
FIG. 3 shows a state in a closed state.

[0014] A hinge mechanism having a double hinge structure includes a connecting plate 15 for connecting the protection lid 13 to the apparatus main body 11,
The connecting plate 15 includes a movable tongue 16 and a fixed tongue 17 provided at both ends. Movable hinge 16
Is located along the edge of the upper surface of the device main body 11 when the protection lid 13 is closed, and connects one end of the protection lid 13 to one end of the connection plate 15. The length of the connecting plate 15 of the present embodiment is shorter than the edge of the upper surface of the device main body 11 as shown in FIG.
As shown in the figure, when the cover 13 is closed, the movable
6 is formed in a round shape so as not to protrude from the outer frame of the device main body 11. The fixing tongue 17 supports the connecting plate 15 on one side (back side) of the device main body 11.

By the way, the main body of the information terminal equipment is generally made of plastic for various reasons such as cost, weight and strength. However, plastic cannot be manufactured in a shape in which the wall thickness changes drastically, and therefore, it must be molded so as to have as uniform a wall thickness as possible. That is no exception in the protective lid 13.
Therefore, a groove 18 for so-called meat stealing is provided at an end of the protection lid 13 which constitutes a part of the movable hinge 16, and by providing this groove 18, the protection lid 13 is closed. The thickness of the same part is almost uniform.

The present embodiment is characterized in that the structure is designed to prevent rattling by utilizing the groove 18 necessarily formed in plastic molding. That is, a groove 18 provided along one end of the protective lid 13 facing the device main body 11 and connected to the movable tongue portion 16 is used as a lid fixing groove. Groove 1 when closing the protective lid 13 near the edge
A protrusion 19 is provided at a position where the protrusion 19 can be inserted into the position 8. In the present embodiment, a plurality of protrusions 19 are provided.

In the above configuration, when the protection lid 13 shown in FIG. 2 is changed from the opened state to the closed state shown in FIG. 3, the projection 19 is fitted into the groove 18.
Therefore, the positioning of the protection lid 13 and the play of the protection lid 13 in the vertical direction (the direction of arrow C in FIG. 1) can be prevented.

In this embodiment, rattling is prevented by using the groove 18 formed on the plastic molding, but a lid fixing groove is provided separately without using the groove. However, the above effect can be obtained.
Thus, the mounting position of the protrusion is less restricted in design as in the case of the groove.

Embodiment 2 FIG. 4 is a diagram showing a main part of a double-tipped structure of the display unit protecting cover mechanism according to the second embodiment, and is a diagram when the device main body 11 is viewed from an arrow B direction in FIG. What is characteristic in the present embodiment is that the protrusion 20 has a shape that can be easily inserted into and removed from the groove 18. In the present embodiment, this is
This is achieved by providing a rounded tip. In addition, as is apparent from FIG. 4, the protrusion 20 has a rounded top side on the display unit 12 side to facilitate the insertion and removal of the groove, and the opposite top side is focused on the function of preventing rattling. Try to be as round as possible.

Thus, the operability of opening and closing the protection lid 13 can be improved.

Embodiment 3 FIG. 5 is a diagram illustrating a main part of a display unit protection cover mechanism according to Embodiment 3.
The inside of the groove 18 is illustrated. The present embodiment is characterized in that a partition plate 22 for forming a slot 21 to be fitted with the projection 19 is provided in the groove 18. Partition plate 2
2, the projections 19 are fitted into the slots 21 and are engaged from the four side directions.
Can be further prevented from rattling in the lateral direction.

In each of the above embodiments, the case where the cover mechanism for protecting the display unit according to the present invention is employed in the information terminal device has been described. It can also be applied as a cover for the operation unit.

[0023]

According to the present invention, since the projection is provided at a position on the device body side which fits into the lid fixing groove provided on the protection lid side, rattling of the protection lid can be prevented. .

Further, the protection lid can be opened and closed more smoothly by forming the projection into a shape that can be easily inserted into and removed from the lid fixing groove.

Further, since the partition plate for forming the slot for fitting with the projection is provided in the lid fixing groove, the rattling not only in the vertical direction but also in the horizontal direction can be further suppressed.
