Abstract

PURPOSE: To allow fan blades to slide on a circumference without using any eyelet, eliminate the need of cutting the sides of the blades for being clamped and kept in an open state, and fix the blades automatically when the blades are wide spread. CONSTITUTION: An A-blade 1 as an inserted fan blade, and a B-blade 2 as a receiving fan blade are formed respectively and a support point 5 is formed at the center of the lower zone of each blade 1 and 2. The A-insertion piece 7 of the blade 1 is inserted in the receiving groove 10 of the blade 2, thereby holding both blades 1 and 2 in a jointed state. Also, the piece 7 is deeper inserted, thereby spreading the blades 1 and 2, and the blades 1 and 2 are kept in a spread state, due to the collision of an A-leading end 8 with an 'a'- receiving end 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple fan which is devised so that it can be opened like a fan and the opened state can be fixed as it is.

[0002]

2. Description of the Related Art A conventional simple fan is (Design Registration No. 562718) of the same applicant, and this is one in which a plurality of fan blades are fixed by metal fittings called eyelets so that they can slide circumferentially. , A cut was provided on the side edge of the fan leaf, and the open state was fixed by sandwiching this cut on the side edge of the adjacent fan leaf.

[0003]

It was best to fix the fan blades with eyelets in order to slide them circumferentially.
The work itself of hitting the eyelets was a time-consuming task. In order to fix the open state, it was a method of making a notch and sandwiching and fixing the edge of the adjacent fan leaf. However, this method of pinching is troublesome since it is performed in units of individual fan blades each time it is opened and closed, and this trouble is doubled as the number of fan leaves increases. In order to solve the problem of the present invention, taking the above into consideration, it is possible to fix and slide the circumference without using an eyelet, and to fix it without using a notch at the time of use. It was made in.

[0004]

[Means for Solving the Problems] Two fan leaves, A leaf and B leaf, are provided, and a fulcrum is provided at the center of the lower region of each fan leaf. A leaf is cut downward from the fulcrum. The slide edge is provided by a notch that draws a circle upward from the end of this notch, and the end portion of the slide edge is provided as the A entry end. In the B leaf, a receiving groove is provided by cutting in the upward direction from the fulcrum, and a guiding groove is provided by a partial circumferential cutting with this receiving groove placed in the center. The circumferential shape of this guiding groove is the thickness of the sheet from the slide edge. Draw the outer circumference only by the amount. The A insertion piece is inserted into the receiving groove while being guided by the guiding groove, and the end of the guiding groove in the inserting direction is provided as the a receiving end, and the point where the A entering end and the a receiving end meet is changed. , The angle at which the fan blades slide around the circumference can be adjusted.

In order to increase the number of fan leaves, a C leaf having a shape in which the A leaf is turned upside down is provided, and the B insert piece which is the insert piece in the opposite direction to the A leaf is inserted into the receiving groove of the B leaf and the receiving side. B leaf which is the leaf of B is provided with b receiving end at the end of the guiding groove on the side opposite to the a receiving end, and by adjusting the position where b receiving end abuts B receiving end of the upper end of B insertion piece. , C leaf slides in the direction opposite to A leaf, and one fan leaf can be added.

To further increase the number of fan leaves, one B leaf, which is a receiving leaf, is added to provide a B'leaf, and an end of the guiding groove having no receiving end is extended by the same circumference to provide an extending groove. Since the contact point with the inlet end of the insertion piece inserted from the back side is extended depending on the length of the extending groove, the B leaf and the B'leaf are fixed in a deviated state. The fan blades can be further increased by changing the length of the groove and the length of the slide edge.

[0007]

[Function] By providing the guide groove, the receiving groove opens greatly, so the insertion piece can be easily inserted. By inserting the insertion piece further deeper, the insertion end and the receiving end hit each other, so that it is not inserted further deeply, any angle It is opened and fixed with. To the receiving groove,
Since it can be inserted from the opposite direction, it is possible to increase the fan blades having the insert pieces in the opposite direction. If the extension groove is provided and the guide groove is extended, the contact point with the inlet end can be moved, so that the B leaf, which is a leaf, can be increased and the B ′ leaf can be provided.
