BACKGROUND ART

Generally, a ski slides at a high speed, and a skier wears a bright color ski clothes and a goggle for implementing a certain field of vision for thereby preventing a certain crash accident.

However, when a user plays skiing at night, since a skin gear is not recognized at night, an accident may be increased. Even when a safety staff standbys, it is impossible to prevent an accident.

DISCLOSURE OF INVENTION

Overcoming the above problems encountered in the conventional art, the object of the present invention is to provide a luminescent ski which is implementing a certain decoration effect and which is easily recognized at night by providing a luminescent unit.

It is another object of the present invention to provide a luminescent ski which does not need an additional operation such a switch operation or a battery exchange that a luminescent unit is blinked using a current which is generated by a movement of a ski.

In order to achieve the above objects of the present invention, in a ski formed of a plate and a binding, a luminescent ski, comprising: a permanent magnet which is rotatably installed in an upper portion of the plate by a rotation wing having the same rotary shaft; an induction coil which is fixedly installed in a surrounding portion of the permanent magnet; and a luminescent unit with a light emitting diode which is connected with an extension of the induction coil, wherein the permanent magnet and the induction coil are detachable in the interior of the binding or to a rear surface of the same.

In order to achieve another object of the present invention, the luminescent unit includes a plurality of transmission windows through which a light of the light emitting diode transmits to the outside.

PREFERRED EMBODIMENT

The preferred embodiments of a luminescent ski according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective diagram illustrating a luminescent ski according to the present invention, and FIGS. 2 and 3 are diagrams illustrating a generator of a luminescent ski.

The luminescent ski is formed of plates (10), bindings (20) and luminescent unit. The above luminescent part is formed of a generation unit (30) and a luminescent unit (40).

The generation unit (30) is formed of a housing (31), a rotation wing (32), a rotary shaft (33), a permanent magnet (34) and an induction coil (35).

The housing (31) is a body in which the rotary shaft (33), the permanent magnet (34) and the induction coil (35) are supported and installed. A protection member (36) which is engaged to the plate (10) and is preferably provided behind a binding (20) is formed in a surrounding portion of the housing (31) and the rotation wing (32) for protecting the rotation wing (32).

In addition, the housing (31) is detachable in the interior or to a rear portion of the plate (10).

The rotation wing (32) is provided in an end outer surface of the rotary shaft (33) and is rotated by wind, and a plate or a propeller-shaped wing which is slanted in a certain direction is formed in an outer surface of the rotary shaft (33) in a radial direction.

The rotary shaft (33) forms a rotation center axis of the rotation wing (32) and passes through one side of the housing (31) in parallel and is engaged with the permanent magnet (34) in the interior of the housing (31). In addition, as shown in FIG. 3, an engaging shoulder (33a) is formed in an outer surface of the housing (31) in order for the rotary shaft (33) to be moved in an inner direction or outer direction of the housing (31). In addition, a bearing (33b) is installed for implementing a smooth operation of the rotary shaft (33).

The permanent magnet (34) is vertically installed in the interior of the housing (31) in such a manner that the permanent magnet (34) is rotatable about a center axis of the rotary shaft (33). As shown in FIG. 4, A N-pole and S-pole are alternately formed in an same outer surface, and a through hole engaged with the rotary shaft (33) is formed in a same inner surface for thereby forming a circular shape. At this time, a rotational force of the rotation wing (32) is transferred as a result of a rotation force of the permanent magnet (34) through the rotary shaft (33).

The induction coil (35) is installed in the interior of the housing (31) fixedly with a certain width from the permanent magnet (34) and generates an induction current by an induction electromotive force which is generated by a variation of a magnetic force by a rotation movement of the permanent magnet (34).

The luminescent unit (40) is formed of a plurality of light emitting diodes which are installed in an upper surface of the plate (10) for being connected with the induction coil (35) extended to the outside of the housing (31) and which are blinked by an induction current applied from the induction coil (35). Preferably, a transmission window (41) is provided in an upper surface of the plate (10) so that the light of the light emitting diode is transmitted to the outside. In the embodiment of the present invention, a plurality of circular transmission windows (41) are provided in an upper surface of the plate (10), and the light emitting diodes are installed in the interior of the transmission window (41).

The luminescent unit (40) may be formed of a plurality of light emitting diodes which emit various color light or may be formed in such a manner that the transmission window (41) generates various colors for thereby enhancing a visional effect.

A reflection plate may be installed in a lower portion of the light emitting diode, so that the luminescent unit is more visible by a blinking operation of the light emitting diodes.

The luminescent operation of the luminescent ski according to the present invention will be described below.

When a user skies on a slope, wearing a luminescent ski, the rotation wing (32) of the generator (30) is rotated by wind, and a driving force of the rotation wing (32) is transferred to the permanent magnet (34) through the rotary shaft (33), and the rotation wing (32) and the permanent magnet (34) are rotated together.

As the permanent magnet (34) is rotated, an induction current is generated in the induction coil (35) by a variation of the magnetic force of the N-pole and S-pole alternately formed in an outer surface of the permanent magnet (34). The thusly generated induction current is applied to the light emitting diode connected with an extension of the induction coil (35), so that the light emitting diodes are lighted.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
