Abstract

PURPOSE:To reduce the number of parts used in a cover structure and the man-hour required for assembling the structure and, at the same time, to prevent the cover, hinge, etc., of the structure from being damaged by malfunctions by providing a rib which comes into contact with the first slope of a projection and bends the projection when the cover is opened and comes into contact with the second slope of the projection after clearing the top of the projection and is fixed to a case when the cover is completely opened. CONSTITUTION:When a cover 1 is opened, a hinge 2 rotates around a rotating axis (c) fixed to a case 3 and a rib (b) comes into contact with the projection (b) of the hinge 2. As the cover 1 is opened further, the rib (b) comes into contact with the slope (d) of the projection (a) and bends the projection (a). When the cover 1 is completely opened, the rib (b) comes into contact with the slope (e) of the projection (a) on the opposite side after passing the top of the slope (d) and the cover 1 is fixed in the opened state. When the rib (b) is pushed in the cover 1 closing direction at the time of closing the cover 1, the rib (b) pushes the projection (a) from the opposite-side slope (e) and clears the slope (e) of the projection (a).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotatable cover structure for a computer terminal device or the like.

[Conventional technology]

Conventionally, this type of cover structure has a hinge 2 with a rotatable shaft and an L-shaped hole 7 for fixing the cover 1 in an open state, as shown in Fig. 3. It has a link 4 rotatably fixed at one end on the side of the cover 1 to be
A pin 5 slidable in an L-shaped hole 7 is fixed to the case 3.

By opening the cover 1, the link 4 slides on the bottle 5, and the bottle enters the tip of the L-shaped hole 7 of the link 4, thereby supporting the cover 2 in the open state.

[Problem to be solved by the invention]

The conventional cover structure described above requires three parts: a hinge, a link, and a pin, and these parts must be assembled, resulting in high costs. Also, when attempting to close the cover from an open state, it is necessary to lift the link upwards, release the fixation, and then close the cover.
The operator is forced to use both hands. Another drawback is that if you try to close the cover without releasing the fixation, the cover, hinges, links, etc. may be damaged. [Means for Solving the Problems] The cover structure of the present invention includes a hinge that rotates around an axis fixed to a case and holds the cover, a first and second sloped surface with one end fixed to the hinge, and a hinge that rotates around an axis fixed to a case and holds the cover. a protrusion that bends due to elastic deformation and has an apex between 1 and 2; and a rib that abuts the second slope and is fixed to the case. [Example] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a side view of one embodiment of the present invention. The cover 1 is connected to the case 3 by a hinge 2 so as to be rotatable and openable, and a side surface of the hinge 2 has a mark A shown in FIG.
As shown in cross-section A, there is a protrusion a with a slope d, and only one end of the protrusion a is connected to the hinge 2, and the protrusion a bends within an elastic range.

At the upper part of the side surface of the case 3 adjacent to the hinge 2, a rib b is provided which hits the slope d of the protrusion a of the hinge 2 and presses the protrusion a of the hinge 2.

When the cover 1 is opened, the hinge 2 is connected to the rotation axis C with the case 3.
The protrusion a of the hinge 2 comes into contact with the rib b. When the cover 1 is further opened, the rib b comes into contact with the protrusion a and the slope d, causing the protrusion a to bend. When the cover 1 is fully opened, the rib b passes over the top of the slope d of the protrusion a, and the rib b comes into contact with the slope e on the opposite side, thereby fixing the cover 1 in the open state.

When closing the cover 1, if force is applied in the direction of closing the cover 1, the rib b will push the protrusion a from the opposite slope e, and the rib b will cross the slope e of the protrusion a.

〔Effect of the invention〕

As explained above, the present invention has the effect of reducing the number of parts, reducing assembly man-hours, and preventing damage to the cover, hinge, etc. due to incorrect operation by providing the cover fixing WI structure made of protrusions on the hinge. ．．

Claims (1)

[Claims] a hinge that rotates around an axis fixed to the case and holds the cover; a protrusion that has one end fixed to the hinge and has first and second sloped surfaces and an apex therebetween, and is bent by elastic deformation; and the case. When the cover is opened, the protrusion contacts the first slope and bends the protrusion, and when the cover is fully opened, the protrusion crosses the apex and contacts the second slope and is fixed to the case. A cover structure comprising a rib.
