  Many of the known bird-proof nets have a structure in which a branch line for holding the net is passed through a hole of a cap fixed to the support and a net is stretched on the branch line. It is difficult to correct the looseness of the branch line or to replace the branch line with a device that penetrates the branch line into the hole of the fixed cap. In addition, bird nets that use a cap-shaped cap that is provided with an open cutout in the periphery and that can be removed from the column are also known, but a cap-shaped cap provided with an open cutout in the periphery There is a problem that the net is easily caught on the protrusion of the open cut portion of the cap, and not only the work is troublesome but also the net is damaged. The invention of the present application solves the problems of these conventional bird nets, and a bird net support cap that can be used for a middle column and a peripheral column and can easily be corrected for loosening of a branch line or replacement of a branch line. It is to provide.

The present invention solves the problems of conventional bird nets. First, it has a cap-shaped cap provided with an open cut portion in the peripheral portion and a peripheral rising portion surrounding the periphery of the cap-shaped cap. In addition, a cap for supporting a bird's net comprising a saucer that can be removably engaged with a cap and a cap is provided.
Second, the bird net described above is provided with a hole provided concentrically with the outer periphery of the saucer on the bottom surface of the saucer, and a releasable latch for locking the side face net is provided in the pore. A support cap is provided.
Thirdly, the locking device for locking the side net is slidable along the pore and can be screwed at one end in a J shape so that it can be fixed at any position. The above-described bird net support cap having the structure is provided.
Fourthly, the above-mentioned bird net support cap is provided in which the rope fixture is detachably locked to the engaging portion of the tray and the support column.

The bird net according to the present invention has a peripheral rising portion surrounding the periphery of the cap and has a tray that is removably engaged with the cap and the column, so that it can be applied not only to the central column but also to the peripheral column. A cap of a bird net that can be provided is provided. In the first aspect of the invention, since the tray is removable with respect to the cap and the support column, when the replacement of the support column or the branch line or the slack of the branch line is adjusted, It can be easily removed, and the bottom of the cap-shaped cap is provided with a tray having a peripheral rising portion that surrounds the peripheral end of the cap-shaped cap, thereby preventing the net from being damaged by the cap-shaped cap.
In the second and third inventions, the bottom surface of the tray is provided with a pore concentrically with the outer periphery of the tray, and the locking tool for locking the side net can be removed and slid into the pore. It is provided and can be suitably used not only as a central pillar but also as a peripheral pillar.
According to the fourth aspect of the present invention, the support can be stably erected by fixing the locking tool to the engaging portion of the tray that can be removably engaged with the support.

  There is known a bird net that can be provided with a cap-shaped cap having an open cut in the peripheral portion at the tip of the support so as to be detachable from the support (FIG. 6). Certainly, this bird net can easily separate the cap from the branch line or support, so you can forget to pass the branch line through the hole in the cap or correct it when the branch line breaks or loosens when you are using it. Simpler and more convenient than traditional bird nets. However, the bird net having a structure in which the cap can be detachably attached comes into contact with the branch line and the net in a state where the open cut part is provided, so the branch line or the net is caught at the corner of the open cut part and the branch line or the like. There was a problem of damaging the net. To prevent breakage of the branch line and net, the wire was tied around the cap and held firmly, but the work of winding the wire and unwinding the wire was difficult, and the part where the wire was wound Cause damage to the net. Moreover, the cap that can be removed with respect to this column is used in a state where the peripheral cut is open, so the movement in the lateral direction of the branch line can be controlled, but it cannot be controlled downward. It is impossible to use a bird net with a cap as a peripheral pillar.

The present invention has a peripheral rising portion surrounding the periphery of the cap-shaped cap with respect to the cap-shaped cap provided with an open cut portion in the peripheral portion, and is provided with a detachable tray for the cap-shaped cap and the support column. The above-mentioned conventional problem is solved by using a bird net support cap, and the bird net support cap provided with the side net locking device of the present invention can be used not only as a peripheral column but also as a concentric circle with the outer periphery of the tray. The side net locking tool provided in the pores provided intermittently in the shape can be removed and used as a middle pillar.
