Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a stand mechanism for small electronic equipment.

[Summary of the invention]

The present invention relates to a small electronic device in which a metal plate member whose one end is formed into a substantially cylindrical shape is joined to a part of the exterior, and a cladding member which is bent into an L-shape is attached to the substantially cylindrical formed portion of the metal plate member. Insert both ends of the stand to provide elasticity in the axial direction of the cylinder,
By opening and closing the stand using the cylindrical shaft as the rotation axis, it is possible to ensure the safety of the small electronic device body against shocks and the like, the durability of the stand mechanism, and to improve the operability.

[Conventional technology]

FIG. 2 shows a bottom view of a conventional small electronic device.

In FIG. 2, reference numeral 2 denotes a tension stand, 4 a case portion on the bottom of the main body, 5 a case groove, 10 a tab, and 11 horizontal holes into which both ends of the tension stand 1 are inserted.

Bend both ends of the tensioned stand 1 into an L-shape, provide two horizontal holes 11 in the bottom case 4 of the main body, insert the L-shaped portions into each of the horizontal holes 11, and use the horizontal hole axis as the rotation axis to open and close the stand. was doing.

[Problems and objects to be solved by the invention] However, the prior art has the following problems.

i) a body essentially made of plastic of varying strength;
It had a stand structure consisting of a metal stand. Therefore, if an excessive force is applied from an unspecified direction while the stand of a small electronic device is standing, the part of the main body that receives the rotation axis of the tensioned stand l will lose its strength and the main body will be destroyed. Sometimes I put it away.

In addition, due to the difference in hardness between the two materials in the stand structure, wear may occur on the plastic body bearing, which may cause durability issues.
The feeling of articulation when opening and closing the stand was sometimes impaired, and patients were likely to feel uneasy about scratching.

Additionally, due to the wear of the plastic, the installation stability of the stand became unstable, making it easy for the stand to topple over due to weak shocks or vibrations.

ii) Lateral hole 11 for inserting the tensioned stand 1
are made in two places on the bottom case part 4 of the main body, but considering a bearing like the one shown in Fig. 3 <a>, the mold becomes complicated, making it difficult to manufacture the mold, leading to an increase in cost, and in some cases, the mold There are also products that cannot be manufactured by the manufacturer. In addition, in the case of making it as shown in FIG. 3(b), manufacturing of the main body plastic mold is relatively easy, but 1. L of tension stand 1
The character part easily penetrated through the side hole 11, and the stable function of the stand could not be maintained permanently.

In any case, if the bearing part of the cladding stand 1 were made of plastic, the wall would be thin, which would pose a problem in terms of strength, and an attempt to increase the strength would result in an increase in the wall thickness.

[Means for solving problems]

In order to solve the above problems, the stand mechanism for a small electronic device of the present invention is provided by joining a metal plate member whose one end is formed into a substantially cylindrical shape to a part of the exterior of the small electronic device. It is characterized by inserting both ends of a tensioned stand into a roughly cylindrical molded part.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. FIG. 1(a) is a longitudinal sectional view of a small electronic device stand mechanism according to the present invention, FIG. 1(b) is a bottom view of the small electronic device according to the present invention, and FIG. 1(c) is a vertical sectional view of a small electronic device stand mechanism according to the present invention. 1 shows a perspective view of the stand mechanism according to the present invention. In FIG. 1, 1 is a tensioned stand, 2 is a metal plate member, 3 is a roughly cylindrical molded part, 4 is a bottom case part of the main body, and 5 is a case part. Groove 6 indicates caulking.

First, the metal plate member 2 is attached to the bottom case part 4 of a small electronic device.
Then, they are joined by caulking 6. When the tension stand 1 is stored, it is completely hidden in the case part 4 on the bottom of the main body by forming the case part groove 5. This prevents the tensioned stand 1 from wobbling.

Further, 3 indicates a generally cylindrical molded portion of the metal plate member 2.

Both ends of the tension stand 1 are bent into an L shape,
The tension stand 1 is inserted into the generally cylindrical molded part 3, and is opened and closed with this part as the center of rotation.

The tension-like stand 1 includes a substantially cylindrical molded portion 3 of a metal plate member 2.
It has elasticity in the axial direction of the cylinder.

As shown in FIG. 1(b), the approximately cylindrical molded part 3 of the metal plate member 2 has notches 7 and 9 and a protrusion 8 in the opening into which both ends of the cladding stand 1 are inserted. When using the stand, the tensioned stand 1 is at the notch 7 position,
When the stand is not in use, the tensioned stand 1 is at the position of the notch 9.

As is clear from Figure 1, since both materials in the stand mechanism are made of metal, both strength and hardness are high, and when excessive force is applied from an unspecified direction such as an impact, the tensioned stand l becomes elastic. , and the bottom case part 4 and the metal stand 1 of the small electronic device can be prevented from being damaged. Additionally, since there is no longer any wear on the metal contact parts, there is no loss of sense of movement when opening and closing the stand, improving operability.

By using the metal plate member 2, rather than considering plastic molding of the bottom case part 4 of conventional small electronic devices,
It is easy, the total mold cost is low, and the material cost is also low. Further, even if the metal plate member 2 is somewhat small, it can be reliably joined to the bottom case portion 4 of a small electronic device by the caulking 6, so that it does not take up a large amount of mechanical space.

Further, in FIG. 5, notches 7 are provided at two or more locations in the cylindrical molded portion 3 of the metal plate member 2.

This allows the stand position to be switched in multiple stages. Since the bearings at both ends of the tension stand 1 are made of metal, it is possible to provide fine irregularities in the cut 7 due to its hardness.

FIG. 6 shows another embodiment in which a metal plate member 2 is bonded to the bottom case portion 4 of a small electronic device, and a cladding stand 1 is attached to the cylindrical molded portion 3 of the metal plate member 2. A metal plate member 2 is attached by caulking 6 so as to protrude from a bottom case part 4 of a small electronic device.

[Effects of the present invention]

As explained above, the present invention joins a metal plate member whose one end is formed into a substantially cylindrical shape to a part of the exterior of a small electronic device, and connects the metal plate member to the cylindrical formed portion of the metal plate member in an L-shape. By inserting both ends of a tension-like stand bent into a cylindrical shape, the stand is made elastic in the direction of the cylindrical axis, and the stand is opened and closed using the cylindrical axis as the rotation axis. This has the effect of ensuring the durability of the mechanism and improving operability.
