Looking at the above documents from the viewpoint of the springs used, the torsion springs that are commonly known are used in [Documents 1] to [3], plate-shaped springs are used in [Documents 4], and steel wire springs in [Documents 5]. In [Document 6], the shape of the cross section is formed in an oval shape to reduce the thickness of the spring. In [Document 7], one or both ends of the elastic spring is spirally wound a plurality of times to reduce the thickness of the spring. There has been effort.

However, the thickness of the torsion springs used in Documents 1 to 3 is twice the thickness of the steel wire, and the plate-shaped spring used in Document 4 is much thicker than the steel wire. The steel wire spring used in 5] is ideal because the thickness of the spring is the same as the thickness of the steel wire, but the length of the elastic part is small, so the steel wire hardly plays the role of the elastic body. The elliptical steel wire used in [6] is still the thickness of the spring is twice the thickness of the steel wire, and winding one end or both ends of the elastic spring used in [7] spirally a plurality of times is [ As shown in Fig. 5 of Fig. 1 or Fig. 10 of Fig. 2, the leftmost part and the rightmost part of the main body plate and the other end are adjacent to each other, so that one end or both ends are spiraled. There is a problem that can not be positioned to cold several times.

The present invention is to solve the problems of the prior art as described above, both ends of the elastic spring to maintain a straight line wound around the clockwise direction in the center and then wound in a counter-clockwise winding, by placing a spiral of the spring The purpose of the present invention is to provide a spring having a thickness corresponding to the thickness of the thinner spring, a slide assembly and a sliding type mobile phone using the same.

The spring according to the present invention comprises a first leg portion formed at one end of a straight line or close to a straight line, a first elastic portion formed in a curve extending counterclockwise by a predetermined length from an end of the first leg portion, and the first elastic portion. And an inflection point formed at the distal end of the elastic portion, a second elastic portion formed in a curve extending clockwise by a predetermined length from the inflection point, and a second leg portion formed in a straight line or near the straight line from the end of the second elastic portion.

In addition, the spring according to the present invention, the first leg portion formed in a straight line or close to a straight line at one end, the first elastic portion formed in a curved curve in a counterclockwise direction by a predetermined length from the end of the first leg portion, A side portion is attached to each other at the distal end of the first elastic portion, and includes a second elastic portion formed in a curve extending in a clockwise direction by a predetermined length, and a second leg portion formed straight or close to the straight line from the end of the second elastic portion.

Preferably, the inflection point is thickened or thickened in the planar direction formed by the first elastic part and the second elastic part, thereby preventing the cutting of the inflection point.

The ends of one or both of the first leg portion and the second leg portion are bent perpendicularly to a plane forming the first elastic portion and the second elastic portion, or form the first elastic portion and the second elastic portion. It is preferable that the ring portion is formed in the same plane or horizontal plane.

Any one or two of the first leg portion and the second leg portion may be bent at least one or more times by a predetermined angle in the middle.

It is preferable to manufacture the slide assembly which concerns on this invention using the above springs.

The sliding type mobile phone according to the present invention is preferably manufactured using the spring and the slide assembly as described above.

The cross section of the steel wire used in the present invention can be used in various ways such as circular, elliptical, square, hexagon, triangle.

Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1, the spring according to the present invention includes a first leg portion 10, a first elastic portion 20, an inflection point 30, a second elastic portion 40, and a second leg portion 50. . The bent portion or the ring portion formed at the end of the first leg portion 10 or the second leg portion 50 is omitted.

The first leg portion 10 is formed to be straight or close to a straight line. If necessary, the first leg portion 10 may be configured such that a slightly curved or middle portion is bent by a predetermined angle.

The first elastic portion 20 extends from the end of the first leg portion 10 and rotates in a counterclockwise direction (meaning that it is curved). In the drawing, the first elastic portion 20 is formed about 1.5 turns counterclockwise. The length of the first elastic portion 20 can be adjusted as needed.

An inflection point 30 is positioned at the end of the first elastic portion 20. The inflection point 30 is a point named for convenience to distinguish the first elastic portion 20 and the second elastic portion 30 rather than a special component.

Near the inflection point 30 may be thickened as necessary, or thickened in the same direction as the plane on which the spring is placed so that the cross section becomes elliptical. When the operation of the spring is repeated, it may occur when the inflection point 30, which is structurally weak, may be damaged, but the damage may be prevented by thickening the inflection point 30.

After passing the inflection point 30, the second elastic portion 40 is rotated in a clockwise direction.

The second elastic portion 40 is formed about 1.3 turns.

The second leg portion 50 extends and is formed at the end of the second elastic portion 40. The length of the second elastic portion 40 can be added or subtracted as needed.

The second leg portion 50 extends and is formed at the distal end of the second elastic portion 40.

The second leg portion 50 is formed to be straight or close to a straight line. If necessary, the second leg portion 50 may be configured such that a slightly curved or middle portion is bent by a predetermined angle.
