Description

{PINWHEEL SCULPTURE}

More particularly, the present invention relates to a vane pivot dynamic molding, and more particularly, to an outer shape of a vane pivot so that the outer shape of the vane pivot can be formed and molded so that the outer appearance of the pivot vane can be formed. And to provide a nighttime lighting effect.

In general, a vane blade has a rotary vane for rotation on its outer side with respect to a central rotary shaft, and the rotary vane rotates about a circumferential surface with respect to the center of the seat surface, And a central rotation shaft is coupled to an upper end of a support.

The above-mentioned pinwheel can be used as a playground for infants and children, and is installed not only in a playground but also in various venues, exhibition halls, and the like, and is used as an application for attracting people's attention through rotation and doubling their interest.

In other words, when the pressure of the air, that is, the wind pressure, is generated in the blades forming the rotary vane, the air moves to the outer blades. At this time, wind pressure is applied to the blades formed by the blades, And is rotated in one direction.

When such a vane is mounted on a molding, the vane is used in combination with a support stand erected on the floor or the top of the molding.

However, most of the above-mentioned vane covers have a regular outer shape. Therefore, when the vane covers are installed on the front or upper side of the molding objects, most of the molding objects are installed in the same shape, and there is a problem of feeling the beauty of the appearance rather than the beauty of the appearance and the advertising effect come.

To solve this problem, various kinds of vane covers have been introduced. For example, a conventionally known vane cover has been disclosed in Korean Patent Registration No. 10-0758919, which discloses a decorative vane cover having a detachable vane cover.

This is achieved by providing an outer sheet having a rotary blade by a radial perforated line and a through hole at the end of the rotary blade and a through hole having a rotary blade by a radial perforated line and a through hole at a rotary blade end, And the rotary blades are simultaneously bendingly coupled to the rotary support shafts by using the through holes and the through holes so that a circular cutting line extending in one direction is formed on the inner end of the outer cut line, The center of the perforated line is configured to coincide with the center of the circle of the coupling hole, so that the perforated line has a three-dimensional shape through the double rotary blades.

In addition, a pinwheel sculpture has been proposed in Korean Utility Model Registration No. 20-0452191.

This is due to the fact that; A rotating part rotatably connected to the supporting stand so as to be rotatable relative thereto and rotating by itself by wind force; A power storage unit in which the rotation output of the rotation unit is converted into a voltage and stored; A light emitting unit driven by electric power stored in the power storage unit and emitting light; And a control unit for applying electric power stored in the power storage unit to the light emitting unit. The power supply unit can illuminate a surrounding area using natural energy such as wind power and solar energy, and can store electric power generated through natural energy.

However, in the case of the above-mentioned vane pivot, the rotary vane is made to emit light through the electric power stored by the rotation of the rotary vane, resulting in a monotonous appearance.

In addition, a pinwheel was disclosed in Korean Utility Model Registration No. 20-0432850.

This enables the rigidity to be maintained by forming a film layer on the surface of the blade member, and the center of gravity and the prevention of abrasion can be prevented through a support rod, a bushing and a plurality of balls and washers, . In addition, since various colors, patterns, and luminous layers can be formed on the blade, it is possible to further satisfy the interest of the user who uses the blade, thereby greatly improving the merchantability.

However, most of the above-mentioned prior art vane pads are formed by folding blades that are rotary blades into sheets of a synthetic resin material at the time of manufacture, which is a problem in that they are difficult to manufacture as large-sized sculptures, and manufacturing costs are increased.

In addition, when applied as a sculpture, the rotation has to be stabilized and continuously performed by the wind, which has been problematic in that it is rotated only by relatively large wind pressure due to friction of the rotating part.
