## Abstract

The present invention relates to a beach ball including a light-emitting device which can be disposed in the beach ball and a light-emitting device accommodating groove which can removably accommodate the light-emitting device in the ball such that the beach ball can be played with even at night.

## Claims

### Claim 1

A beach ball formed with a known air injection port and having light-emitting devices and light-emitting device accommodating grooves so that the beach ball can be played with even at night, wherein each of the light-emitting devices comprises:
a light source formed by cutting a PCB board to a minimum size for accommodation of only one LED and thereafter adhering one LED to each one PCB board thus cut;
an electric source comprising a subminiature 3-V mercury cell; and
electric wires which are two elastic thin steel wires, upper portions of which are attached to the underside of the PCB board, and which supply the light source with electricity of the electric source,
wherein the electric wires comprise:
electric source connection portions formed by narrowly bending middle portions of the steel wire inwards so that the middle portions can accommodate the electric source; and
electric wire support portions formed by spreading both end portions of the electric wires outwards so that the end portions can contact with an inner wall of a main body of the light-emitting device accommodating groove.

### Claim 2

A beach ball formed with a known air injection port and having light-emitting devices and light-emitting device accommodating grooves so that the beach ball can be played with even at night, wherein each of the light-emitting device accommodating grooves comprises:
a cover which is produced from transparent or translucent soft synthetic resin or rubber and which has a lid for covering the light-emitting device accommodating groove so that the light-emitting device is not withdrawn after insertion of the light-emitting device into the light-emitting device accommodating groove or for covering the light-emitting device accommodating groove and thus preventing exposure of holes in an outer circumferential surface of the beach ball also after the light-emitting device is withdrawn; and a body which is in the form of a hollow cylinder inserted into a main body, wherein the outer diameter of the body is similar to the inner diameter of the main body and the length of the body is 20 to 30% of the length of the main body, and thus the body is forcedly fitted deeply into the main body to block an inlet of the main body; and
two to five main bodies which are elastic cylindrical body having a closed bottom and produced from transparent or translucent soft synthetic resin or rubber and which are formed integrally with the beach ball,
wherein, on the top of each main body, a flange is formed extending from an outer circumferential surface of the main body, and four pairs of supporting means are formed on an inner wall of middle part of the main body at equal intervals, and a light source accommodating groove for accommodating the light source is formed at a lower end of the main body,
wherein the supporting means is an elongate long groove with such a width that an outer circumferential surface of the electric source and the electric wires can be inserted in the groove or is two elongate protruding lines formed with such a narrow spacing of the width, and the outer circumferential surface of the electric source and electric wire support portions are positioned in the groove or between the two protruding lines and thus are not deviated.
