Description

[Detailed description of the invention] The present invention relates to a round, expandable, round-shaped butthole for attaching seeds, etc., to a main stream of seeds, etc., and a large number of them extend from the front part of a cylindrical outer frame 1 whose both ends are overlapped and connected to each other. A front edge 3 is formed by bending the strips 2 inwardly at right angles with respect to the outer frame 1, and overlapping adjacent strips 2 with each other to form a front edge 3. At the same time, a presser plate 5 is arranged on the back side of the opening, the end plate 4 and the presser plate 5 are integrally connected through the opening, and the inner circumferential end of the front edge 3 is bent forward to engage. A locked edge 7 is provided with a retaining edge 6 and is formed by bending the peripheral edge of the mirror plate 4 backward.
This relates to a round butt end winding which is arranged on the outer periphery of the locking edge 6 so as to be locked with the locking edge 6.

In the conventional round-shaped butthole A' whose diameter can be expanded and contracted, the first
Front edge 3' formed by overlapping strips 2' as shown in the figure.
Since there was only a mirror plate 4' placed on the back side of the
There is a disadvantage that the inner circumferential edge of the front edge 3' is visible and the appearance is unsightly, and there is also a disadvantage that rainwater easily enters.

This invention was made in view of the points mentioned above, and the purpose of this invention is that the inner circumferential edge of the front edge is not visible due to the mirror plate placed on the front side, giving a good appearance and preventing rainwater from penetrating. It offers round-shaped Kiguchimaki.

The present invention will be explained in detail below using examples.

As shown in FIG. 7, on one side of the strip plate B, a large number of notches 9 are made through the back folded piece 8 to form a large number of strips 2, and on the other side of the strip plate B. A front folded piece 10 is formed.

This band-shaped plate B is wound into a cylindrical shape to form an outer frame 1, and a connecting part 11 provided at one end of the outer frame 1 and a connected part 12 provided at the other end are slidably overlapped. be.

A front protruding flange portion 13 is formed by folding back the back folding piece 8 on the front end side of the band-shaped plate B, and each strip piece 2 is bent inward at a right angle with respect to the outer frame 1. At the same time, adjacent strips 2 are overlapped with each other to form a front edge 3, and a locking edge 6 is formed by bending the tip of each strip 2 at a right angle toward the front.

A front folding piece 10 at the rear end of the outer frame 1 is folded forward.

A peripheral edge rising portion 14 is formed on the outer periphery of the disc-shaped mirror plate 4 and projects toward the front side.A locked edge 7 extends rearwardly from the peripheral edge rising portion 14. Flange 1 on the outer periphery
5 is extended, and a mirror plate 4 is provided on the front side of the opening of the front edge 3.
The locking edge 7 is positioned outside the locking edge 6.

A presser plate 5 having spring properties is arranged on the back side of the opening of the front edge 3, and the end plate 4 and the presser plate 5 are connected by a connecting member 16.

The round book opening A constructed as described above is made of a copper plate, a steel plate, a resin-coated metal plate obtained by coating a thin metal plate with a synthetic resin, a metal plate with an uneven pattern, or the like.

Next, the operation of the round main mouth roll A of the present invention will be explained.

By changing the amount of overlap between the connecting portion 11 and the connected portion 12, the diameter of the outer frame 1 can be freely changed.

At this time, as shown in FIG. 2, the state in which the locking edge 6 of the outer frame 1 and the locked edge 7 of the end plate 4 are locked is the maximum diameter, and as shown in FIG. The minimum diameter is when the more extended flange 15 touches the forward protruding flange 13 of the outer frame 1.

Therefore, when installing, change the diameter of the round butt end wrap A to match the end 17 of the seed, etc., and
The outer frame 1 is fitted onto the outer frame 1, and nails 18 or the like are driven from the outer periphery of the outer frame 1 to fix it.

As described above, the front edge of the present invention is formed of strips, so it can be bent into any shape by changing the overlapping margin of the strips, and the outer frame can be bent into any shape by changing the overlapping margin at both ends of the outer frame. Not only can the diameter of the frame be freely adjusted, but since the front side of the opening on the front edge is closed off with a mirror plate, the inner edge of the front edge is not visible, giving it a good appearance and preventing rainwater from seeping in. There is no need to worry about it, and since the holding plate is placed on the back side of the opening in the front edge and the end plate and the holding plate are integrally connected through the opening, even if the end plate is on the front side, the end plate cannot be moved. It can be securely attached to the outer frame, and the inner peripheral end of the front edge is bent forward to provide a locking edge, and the peripheral edge of the end plate is bent backward to form a locking edge. Since it is arranged on the outer periphery of the locking edge so that it can lock with the locking edge, when the diameter of the outer plate is maximized, the locked edge and the locking edge lock, and from the outer frame to the end plate. It has the advantage that there is no risk of it coming off.
