Definitions

• the present invention relates, in general, to pinwheels for leisure, decorative or exhibition purposes, and, more particularly, to a decorative pinwheel having a retractable inner pinwheel, which is constructed so that inner and outer sheets having radial cut lines overlap each other, the overlapping inner and outer sheets are connected to a pivot unit, rotary cut lines are provided in the inside ends of the cut lines of the outer sheet in an arc shape, and respective blades are folded and fitted to the pivot unit, so that the inner pinwheel protrudes through the rotary cut lines or is retracted to its original position, thus allowing the pinwheel to be changed into a pinwheel having a plurality of rotary blades, and providing a better three-dimensional effect, and the rotating speed of the pinwheel can be increased or reduced using variation in air resistance depending on the amount that the retractable pinwheel protrudes, thus allowing the pinwheel to be used more efficiently and effectively.
• Background Art
• pinwheels which are used as children's toys or decorations for advertisement or publicity, have a plurality of blades which are made of plastic resin or paper. The blades are secured to a pin or a shaft.
• the blades of the pinwheel are formed by folding a single sheet. That is, the sheet, comprising a square plane, is prepared, and is cut in directions from the center of the sheet to free ends thereof at regular angular intervals, thus forming a plurality of blades. Through holes are formed in the center of the sheet and the free ends of the blades. Next, the free end of each blade is folded towards the center of the sheet so that the central through hole of the sheet communicates with the through holes formed in the free ends of the blades. In this state, a pin or shaft is inserted into the through holes so that the free ends of the blades are secured to the center of the sheet.
• each of front and rear ends of the shaft for supporting the blades is covered with a cap or the like.
• pinwheels have been widely used as toys for babies or children. Further, pinwheels are installed in a variety of event halls, exhibition halls, or gas stations, and have been widely used as an auxiliary means of attracting public attention or arousing public interest.
• pinwheels have a fixed shape. Recently, pinwheels have been used in many places. However, if the decorative pinwheels installed in a given place have the same shape, people may become bored with the pinwheels. Thus, the pinwheels having the same shape may have a reduced advertisement, exhibition, or decorative effect.
• the pinwheels since most general pinwheels are formed by folding one sheet, the pinwheels have a similar shape and construction. Thus, the general pinwheels do not have beautiful and unique designs. In order to produce new shapes, design, or color, many sheets overlap each other, and/or several sheets having completely different shapes overlap each other. However, this results in increased production costs, and reduces manufacturing efficiency, thus hindering mass production.
• an object of the present invention is to provide a pinwheel, which deviates from an existing fixed or uniform shape, thus having a novel shape, and provides an excellent decorative effect when the pinwheel rotates, and which enables control of the rotating speed of the pinwheel, thus realizing a better three-dimensional shape and more spectacular rotation.
• an object of the present invention is to provide a pinwheel, in which an inner sheet and an outer sheet, each having radial cut lines therein, are separately provided, and rotary cut lines are provided in the inside ends of the radial cut lines of the outer sheet in an arc shape, and blades separated from each other by the radial cut lines of the inner and outer sheets are simultaneously connected to a pivot unit, so that an inner pinwheel formed by the inner sheet is positioned inside an outer pinwheel formed by the outer sheet, and the inner pinwheel formed by the inner sheet can be axially protruded from and retracted into the outer pinwheel formed by the outer sheet.
• a decorative pinwheel having a retractable inner pinwheel has a better three-dimensional effect and a decorative effect, thus providing a more beautiful appearance and beautiful rotation when the pinwheel is rotated, and controls the rotating speed of the pinwheel using variation in resistance to wind depending on the protruding distance of a pinwheel formed by an inner sheet, thus being more efficiently utilized to suit the place or purpose.

• the process of assembling the pinwheel according to the present invention is as follows. As shown in FIG. 3, after the inner sheet 20 is placed on the outer sheet 10, the inner and outer sheets are rotated in opposite directions. At this time, the lower ends of the cut lines 21 and 21' in the inner sheet 20 are alternately inserted into the rotary cut lines 15 and 15' formed in the lower ends of the cut lines 11 and 11' in the outer sheet 10.

• the pinwheel when the blades 22 and 22' of the inner sheet 20 are pushed into the blades 12 and 12' of the outer sheet 10 and are rotated, the pinwheel has a general pinwheel shape. Conversely, when the blades 22 and 22' of the inner sheet 20 are rotated to protrude out from the blades 12 and 12' of the outer sheet 10, the number of blades of the pinwheel is doubled. [52] Therefore, the shape of the pinwheel is changed by the protrusion or retraction of the inner sheet 20, or the appearance of the pinwheel is changed according to the protruding distance of the blades, so that various shapes of pinwheels are obtained according to the intended purpose.
