Description

[Detailed description of the invention] The present invention relates to a cornflower used to decorate the tip of a pole such as a carp streamer during the May Festival.

As shown in Fig. 1, this type of conventional arrow wheel has an arrow connecting plate a through which a bush b through which the arrow shaft is inserted is inserted, and a symmetrical two-part receiving member c which can be superimposed together with the bush. and a cover member d, each having radial arrow fitting grooves c' and d',
A pipe-shaped arrowhead e is inserted into the arrowhead fitting groove c′ of the receiving member c.
After that, cover the cover member d and insert the other part of the arrowhead into the arrowhead fitting groove.
d', and then screws f are passed through the receiving member c, the arrowhead e, and the cover member d, and the screws are tightened and fixed as shown in the figure. It was stable and required skill to assemble.

As will be explained in the examples below, in the present invention, before a cover member is placed on a member corresponding to the receiving member, a pressure plate integrally provided with a bushing is attached to the shaft hole formed on the receiving member side. This has been improved so that it can be fitted and placed over each arrow, and can be engaged from each arrow projecting in the radial direction using only the receiving member.

A preferred embodiment of the invention will be described with reference to FIGS. 2-6.

The tip of the barrel 2 of the arrow 1 is slightly tapered and a third T-shaped engagement piece 3 is attached to the tip.
It is formed as shown in the figure, and the arrowhead 5 at the outer end of the arrowhead slightly protrudes from the blade 4 as is known in the art.

The arrow connecting plate 6, which has a circular or polygonal shape, through which the bush 9 is inserted into the shaft hole 8 of the central boss portion 7 on a arrow shaft (not shown), has a two-piece shape of a receiving member 10 and a cover member 11, which can be superimposed. (See Figure 7).

A plurality of arrow fitting grooves 12 are provided in the receiving member 10 in the radial direction, and a cross-shaped engagement groove 13 into which the above-mentioned engagement piece 3 is fitted is provided at the center end of each fitting groove 12.

Reference numeral 14 is a pressure plate having a half-cutting bush 15, which is the length of the bushing 9 cut in half, on the lower surface of the center, the radius of which is set so that it slightly protrudes from the position of each of the engagement grooves 13, and the pressure is A second engaging groove 16 is provided on the lower surface of the fixed plate 14 to match each engaging groove 13 above, and a short groove 17 is further provided in the radial direction from the outer edge of the fixed plate.

Another half-cutting bush 21 is fitted into the shaft hole 8 on the side of the cover member 11, or a bush provided integrally with the compression plate 14 is fitted. Further, a second fitting groove 22 is provided that matches the arrowhead fitting groove 12 of the receiving member 10,
Furthermore, the depression groove 23 in contact with the compression plate 14 is
It is formed around the half-cut bush 15 on the lower surface of 4.
Reference numeral 24 denotes a connecting ring that connects all the bolts 5 in an annular manner.

In this embodiment, approximately half the circumference of the arrowhead 2 is fitted into the fitting groove 12 from the arrow of the receiving member 10, and at the same time, approximately half the circumference of the engagement piece 3 is fitted into the engagement groove 13, and then,
Insert the half-cutting bush 15 of the pressing plate 14 into the shaft hole 8 on the receiving member 10 side and press down to connect the second engagement groove 16 and cut groove 17 to the engagement groove 13 of the arrowhead 2 and the arrowhead fitting groove 1.
The arrow shaft 2 is inserted into the exposed portion of the arrow shaft 2 and crimped, and the cover member 11 is placed over the arrow shaft 2 as shown in FIG. Fasten the receiving member 10 and cover member 11 with screws 25 at a part unrelated to the bolt 2.
Connect by. When packed in a box, without covering the cover member 11, the arrowhead 2 is centered around the engagement piece 3 sandwiched between the engagement groove 13 and the second engagement groove 16.
While fitting into the cut groove 17, stand it up as shown in FIG. This uprighting allows the bag to be transported as it is in the box, and at the time of sale, the arrowheads 2 are placed in the radial direction as shown in FIG. 7 and covered with the cover member 11, and fixed with screws 25.

As has been made clear from the above description, the present invention has a half-cut bush 15 (or bush 8) of the compression plate 14 that is covered by the cover member 11.
The arrow 1 can be supported by the receiving member 10 by simply fitting it into the shaft hole 8 on the receiving member 10 side and pressing it down. Therefore, the receiving member and the cover member are connected by inserting the cover member and using a screw that also passes through the arrow head. Compared to the conventional structure, which is assembled in the form of a arrow wheel, a large number of arrow wheels 2
This has the effect that the assembly can be easily locked using only the receiving member 10.
