Abstract

There is disclosed a portable sound equipment comprising a support body formed in a gentle curve; electronic bodies provided in both ends of the support body, respectively, and exhaustible from the support body and rotatable to be folded or unfolded in an exhausted state; and a hinge unit configured to provide a shaft for the rotation, wherein the hinge unit comprises a connection portion projected from one end of the support body; a hinge rotatably coupled to the connection portion; a cylinder connected to the hinge and loaded in the electronic body; and a hinge spring having one end fixed to the cylinder and the other end supporting the electronic body to generate a restoring force which makes the exhausted electronic bodies become drawn into the support body, and when the electronic bodies are drawn into the support body is caught in the connection portion with respect to the rotational direction.

First claim

What is claimed is:

1. A portable sound equipment comprising:
a support body formed in a gentle curve;
electronic bodies provided in both ends of the support body, respectively, and exhaustible from the support body so as to selectively switch a drawn-out state and a drawn-into state, wherein the electronic body is rotatable to be folded or unfolded in the drawn-out state; and
a hinge unit configured to provide a shaft for the rotation,
wherein the hinge unit comprises,
a connection portion projected from one end of the support body;
a hinge rotatably coupled to the connection portion;
a cylinder connected to the hinge and loaded in the electronic body; and
a hinge spring having one end fixed to the cylinder and the other end supporting the electronic body to generate a restoring force for the electric bodies from the drawn-out state to the drawn-in state, and
wherein the electronic body is caught to the connection portion in case of the drawn-into state such that the electronic body is restricted to rotate.

2. The portable sound equipment of claim 1 , wherein the rotation of the electronic bodies is restricted by the electronic bodies covering a predetermined area of the connection portion and the rotation is facilitated when the drawn-out electronic bodies exposes the area of the connection portion outside.

3. The portable sound equipment of claim 2 , wherein an outer circumference of the connection portion of the support body is smaller than an inner circumference of an inner end of the electronic body.

4. The portable sound equipment of claim 2 , wherein an outer circumference of the connection portion of the support body becomes larger inwardly to fixedly fit the electronic bodies in the support body when the electronic bodies are drawn a specific distance into the support body.

5. The portable sound equipment of claim 1 , further comprising:
a projected end formed in an outer circumference of an outer end of the support body and having the electronic bodies caught thereby, when they are drawn into the support body.

6. The portable sound equipment of claim 1 , further comprising:
a support ring coupled to one side of the cylinder and supporting one end of the hinge spring; and
a support bracket fixedly coupled to an inner end of the electronic body and supporting the other end of the hinge spring.

7. The portable sound equipment of claim 6 , further comprising:
a rib provided in an inner surface of the electronic body; and
a slit provided in an outer surface of the support bracket to be insertedly fitted to the rib.

8. The portable sound equipment of claim 1 , wherein the connection portion further comprises,
an inclined area formed in a corresponding area to the electronic bodies, when the folded electronic bodies are unfolded, and configured to provide a force applied to the electronic bodies along the exhausted direction.

9. The portable sound equipment of claim 1 , wherein the support body comprises,
an upper sheath;
a lower sheath coupled to a lower end of the upper sheath; and
a wire bracket provided between the upper sheath and the lower sheath and configured to fix a predetermined inner area of the connection portion.

10. The portable sound equipment of claim 1 , wherein the connection portion comprises,
a ball bracket having the hinge insertedly fitted thereto; and
a fixing bracket coupled to both sides of the ball bracket.
