By the wide portion 20A, the bridging piece portion 20 is reinforced, and the strength and rigidity of the portion supporting the load of the wire W and the pole portion 3 are improved.

The use method (action) of the above-described bird flying prevention apparatus of the present invention will be described.
As shown in FIG. 1, the base part 2 is installed on a handrail, and the binding band B is inserted through the window parts 4 and 4 and wound around the handrail. At this time, it is desirable that the binding band B is moved to either the left or right of the window parts 4 and 4 and the center part is left open. While the one end of the binding band B is pulled and locked with a locking tool, the base portion 2 is fastened and fixed. At this time, the binding band B comes into contact (pressure contact) with the inner projecting piece portions 21 and 21, and transmits the tightening force as a pressing force with an appropriate strength to a wide area. Further, since the corner portions 14, 14 are rounded, the force does not concentrate on the binding band B, and the risk of breakage is extremely low even when tightened strongly.

The base portion 2 is in contact with the handrail with four small protrusions 5, 5, 5, and 5 and supports the tightening force in a concentrated manner (at four points). It is installed stably without rattling and preventing slipping.
Next, the pole portion 3 is screwed to the base portion 2 and the nut is firmly tightened using a tool such as pliers. A ring is formed through the wire W in the two perforations 3a and 3b of the pole portion 3, and the sleeve is swaged and stopped. The ring of the wire W is hooked on the spring 40, the spring 40 is hooked on the holes 3a and 3b of the other pole portion 3, and the two wires W are installed. It is also desirable that the number of perforations 3a, 3b and wires W be 3 to 6 (books). Thus, by providing a plurality of wires W, it is possible to prevent both a relatively large bird such as a pigeon and a relatively small bird such as a sparrow from flying. Since the base part 2 is reinforced by forming the wide part 20A on the bridging piece part 20, the holding strength of the pole part 3 is improved, and deformation is caused when an external force is applied to the wire W or the pole part 3. The pole part 3 is firmly supported without doing.
Although not shown in the drawings, when the support column 1 is installed on a flat surface, screws are used to insert the screws into the plurality of holes 9 to fix the base portion 2.

  The design of the present invention can be changed. For example, as shown in FIG. 5, the base portion 2 may have a semicircular arc shape in a side view. Moreover, as another example of the base part 2, as shown in FIG. 6, it is also preferable that the intermediate connection parts 23 and 23 are bent at a right angle. As another example, as shown in FIG. 7, the intermediate connecting portions 23, 23 are bent horizontally from the upper ends of the leg pieces 22, 22, so 23 may be formed in the same plane. In any shape, the base part 2 having an arch shape in a side view can be stably installed on the curved surface, and a single metal plate piece 10 is punched and folded by pressing. It has the same configuration in that the horizontal inner projecting piece portions 21 and 21 are integrally formed by bending.

  As described above, the bird flying prevention apparatus according to the present invention is a bird flying prevention apparatus that prevents the birds from flying by laying the wire W between the plurality of support posts 1 and 1 that are spaced apart from each other. In this case, the support columns 1 and 1 have an arch-shaped base portion 2 having a pair of window portions 4 and 4 through which the binding band B is inserted, and a vertical configuration on the base portion 2 so that the wire W is suspended. Since the base portion 2 is integrally formed with the horizontal inner projecting piece portions 21 and 21 by plastic working (pressing) of one piece of the metal plate 10, The columns 1 and 1 can be stably installed on the railings of the stairs and pipes, and it is possible to reliably prevent birds from flying and stopping. The base portion 2 of the column 1 can be stably placed on the curved surface and can be easily fixed to a handrail, a pipe or the like. The base portion 2 can receive the tightening force of the binding band B with a wide area by the horizontal inner protruding piece portions 21 and 21, and can improve the stability of the support column 1. Therefore, the efficiency of the installation work is remarkably improved and the work time can be shortened. Moreover, since the base part 2 is formed from one piece of the metal plate 10 by plastic working, it can be easily manufactured at a low cost with a small number of steps.

  In addition, since the base portion 2 is bent so that the outer ends of the inner protruding piece portions 21 and 21 form rounded corner portions 14 and 14, even when the binding band B is strongly tightened, The binding band B is hardly damaged and can be installed over a long period without breaking.

  In addition, since the base portion 2 is provided with the small protrusions 5 at the four locations of the lower end portion 12, the fastening force of the binding band B is intensively supported at four points, and the surface of an uneven pipe or the like is provided. It is fixed without rattling and the stability of the column 1 can be improved.

  In addition, the base portion 2 has a bridging piece portion 20 to which the pole portion 3 is fixed, and a wide portion 20A is formed at an intermediate position in the left-right direction of the bridging piece portion 20, so that the holding strength of the pole portion 3 is increased. The base part 2 can support the pole part 3 reliably without being deformed. In addition, the bridging piece 20 can be formed simultaneously with the partial punching of the inner projecting piece 21, 21.

  Further, since the inner projecting piece portions 21 and 21 are formed with a plurality of mounting hole portions 9 penetrating in the vertical direction, the support column 1 can be easily installed on a flat surface. That is, the support column 1 can be installed in correspondence with both a curved surface such as a handrail and a pipe, and a flat surface.
