Abstract

PROBLEM TO BE SOLVED: To provide a lid opening/closing assisting mechanism of a small electronic apparatus with a simple structure, less parts, and no additional part where a case lid easily opened/closed with fingers, related to a small electronic apparatus requiring a case lid. SOLUTION: A case lid opening/closing assisting mechanism of a small electronic apparatus is provided which comprises a case lid 1, a push button 4, a rubber key 6, a board 5, and case 2 and 3 where the push button 4, the rubber key 6, and the board are housed. Pushing the push button 4 releases engagement between a holding claw 4a and a hooking claw 1a of the case lid, and a key top 6a integrally molded with the rubber key 6 for general input which has been pushed by the hooking claw 1a of the case lid 1 is elastically restored, allowing the hooking claw 1a of the case lid to push up the case lid 1 in opening direction. Further, the holding claw 4a of the push button 4 pushes up the hooking claw 1a of the case lid 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case cover opening and closing assist mechanism for a small electronic device having a case cover.

[0002]

2. Description of the Related Art A conventional small electronic device having a case lid requires a force for lifting the case lid as a means for easily catching a finger when opening and closing, and requires a metal as a separate part to obtain elasticity. It is necessary to have a torsion spring, a plate-shaped spring, a coil compression spring, a plastic molded spring, or another part for raising the case lid. there were.

[0003]

The conventional small-sized electronic device with a case lid requires another special part to make it easy to open and close the case lid with a finger so as to make it easy to open. However, there has been a problem that the cost increases and the assembling process also increases.

[0004] It is an object of the present invention to provide a small electronic device in which the case lid can be easily opened and closed without increasing the number of parts.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a case cover, a push button for fixing the case cover, a case for storing the push button, and a case cover opening direction. A case lid opening / closing assist mechanism for a small electronic device composed of rubber having a convex shape for lifting.

In this configuration, the convex rubber is
When the push button is pressed to open the case lid, the engagement between the hook claw of the case lid and the holding claw of the push button is released, and the elastic force of the convex rubber is applied to the case lid. The case lid rises by pushing up the tip of the hook. Further, when the push button returns, the holding claw of the push button pushes up the hooking claw of the case lid.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of an auxiliary opening / closing mechanism for a case lid according to the present invention.

FIG. 1 is a plan view of a small electronic device according to an embodiment of the present invention. 1 is the case lid, 2 is the upper case,
3 is a lower case, 4 is a push button, 5 is a board | substrate, and 6 is a rubber key.

FIG. 2 shows the portion B in FIG. 1 in detail.

FIG. 3 shows the side B of FIG. 1 from the side.

FIG. 4 is a cross-sectional view taken along the line AA ′ of FIG. 1 and shows a state where the case lid 1 and the push button 4 are held.

FIG. 5 is a sectional view taken along the line AA 'in FIG. 1, and shows a state in which the case cover 1 is pushed up when the push button 4 is operated.

On the back side of the case lid 1, a hook 1a is provided to prevent the case lid 1 from opening. The case 2 is provided with a hole 2b through which the hook 1a of the case lid and the holding nail 4a of the push button 4 pass. Case 3
Is provided with a surface 3a for guiding the push button 4.

The push button 4 is provided with a rod-shaped arm 4b. The rod-shaped arm 4b has an elastic force and extends in a direction perpendicular to the sliding direction of the push button 4. The vertical direction is held by a surface 2c provided on the case 2 and a surface 3a provided on the case 3, and a fixing rib 2a is provided on the case 2 to accommodate the bar-shaped arm 4b. Further, a hole 4c provided in the rubber key 6 for passing the key head 6a is provided. Further, a holding claw 4a for fitting with the hook claw 1a of the case lid is provided in a direction perpendicular to the sliding direction of the push button.

The substrate 5 is fixed to the case 2. The rubber key 6 is a normal general input key, and is used for the case cover 1.
The key head 6a for pushing up the hook 1a is integrally formed, and is fixed between the case 2 and the substrate 5.

Next, the operation of the auxiliary mechanism for opening and closing the case lid configured as described above will be described.

When the case cover 1 is opened, when the protrusion of the push button 4 is pressed in the state shown in FIG. 4, the engagement between the holding claw 4a and the hook claw 1a of the case cover 1 is released, and the protrusion of the rubber key 6 is performed. The resilient force of the key head 6a of the part releases the resilient force to push the hook 1a of the case lid 1 in the direction of opening the case lid 1. (State shown in FIG. 5) By the time the push button 4 is completely returned to the original position, the holding claw 4a of the push button 4 further pushes up the hook 1a of the case lid 1. (State shown in FIG. 6) As a result, the gap between the case lid 1 and the case 2 is greatly opened, so that it becomes easy for a finger to hook and the case lid 1 is easily opened.

In closing the case lid, when the case lid 1 is pushed downward in the state of FIG. 6, the hook 1a of the case lid 1 starts to be fitted with the holding claw 4a of the push button 4. Further, while pushing down the convex portion 6a of the rubber key 6, the hook 1a of the case lid and the holding claw 4a of the push button 4 are fitted, and the case lid 1 is held. (State shown in FIG. 4) In the embodiment, a key head 6 similar to a rubber key with a click is used.
Although a is provided, other elastic members can be used. For example,
It may be made of an elastic rubber body having a low rubber hardness.

[0019]

The present invention is embodied in the form described above, and has the following effects. In the opening / closing assist mechanism for the case lid of small electronic equipment, the case lid pops up in the opening direction by pressing the push button for opening and closing the case lid, and the case lid pops up, making it easier for the fingers to hook the edge of the case lid. The lid can be easily opened and closed.

By forming the rubber key for popping up the case lid in the opening direction integrally with other general input keys, parts can be reduced, assemblability can be improved, and cost can be reduced.
