Embodiments for Carrying out the Invention

[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show the first embodiment of the bracelet of the present invention. As shown in FIG. 2, this bracelet includes a bracelet body 1 and bird intrusion prevention members 2 attached to both longitudinal ends of the bracelet body 1.

[0008] The wristband body 1 is formed of an extruded aluminum alloy material. As shown in FIGS. 1 and 2, it has a cylindrical shape with a square cross-section having an upper wall 5, a lower wall 6, and a pair of side walls 7, 7. Slits 3, which serve as locking portions for the bird intrusion prevention member 2, are formed in the upper wall 5 and the lower wall 6 at both longitudinal ends of the wristband body 1 in a direction intersecting the longitudinal direction. Long holes 10 for inserting bolts 9 for fixing the wristband body 1 to the utility pole 8 are formed in the side walls 7, 7 of the wristband body 1. Further, mounting holes for mounting devices (not shown) such as insulators for receiving electric wires are appropriately formed in the wristband body 1.

[0009] The bird intrusion prevention member 2 is formed by cutting an aluminum profile to a predetermined length. As shown in FIG. 1(a), it has inclined portions 11, 11 that incline outward in the longitudinal direction of the wristband body 1 at the upper and lower portions, and locking portions 4, 4 project upward and downward at the tip ends of the respective inclined portions 11, 11. As shown by the arrow in FIG. 1(a), when this bird intrusion prevention member is pushed into the hollow portion 12 from the small end of the wristband body 1, the upper and lower inclined portions 11, 11 are elastically deformed so as to bend inward, and then the locking portions 4, 4 at the upper and lower ends are elastically locked to the slits 3 of the wristband body 1 and fixed to the wristband body 1 as shown in FIG. 1(b). By attaching the bird intrusion prevention members 2 to both ends of the wristband body 1 in this way, it is possible to prevent birds from entering the hollow portion 12 of the wristband body 1 and building nests.

[0010] This wristband is fixed to the utility pole 8 by bands 13 wound around the utility pole 8, bolts 9, 9, and nuts 14, 14 in the same manner as the conventional one (see FIG. 2). Since the wristband body 1 of this wristband is made of an aluminum profile and is lightweight, the installation work on the utility pole 8 is easy.

[0011] FIG. 3 shows a second embodiment of the wristband of the present invention, and the shape of the bird intrusion prevention member 2 is different from that of the first embodiment. The bird intrusion prevention member 2 is formed in a substantially U-shape having upper and lower horizontal walls 15, 15 and a vertical wall 16 as shown in FIG. 3(a), and a locking portion 4 is formed downward at the tip end of the upper horizontal wall 15, and a locking portion 4 is formed upward at the tip end of the lower horizontal wall 15. As shown by the arrow in Fig. 3(a), when the upper and lower horizontal walls 15, 15 are pushed into the end of the hinge body 1 from the outside so as to fit, the upper and lower horizontal walls 15, 15 are elastically deformed so as to bend outward, and then the locking portions 4, 4 provided at their tips are resiliently locked to the slit 3 of the hinge body 1 and fixed to the hinge body 1 as shown in Fig. 3(b).

[0012] Figs. 4 and 5 show a third embodiment of the hinge of the present invention. As shown in Fig. 4(a), the bird intrusion prevention member 2 is in the shape of a rectangular plate. The bird intrusion prevention member 2 has upper and lower dimensions substantially the same as the upper and lower dimensions of the hollow portion 12 of the hinge body 1, and left and right dimensions smaller than the left and right dimensions of the hollow portion 12 of the hinge body 1. In the hinge of the present embodiment, as shown in Fig. 4, the bird intrusion prevention member 2 is inserted into the hollow portion 12 from the small end of the hinge body 1 and caulked by pressing with a press 17 from above and below. At that time, as shown in Fig. 5(a), by pressing through the pressing portion 22 with a pointed tip, as shown in Fig. 5(b), the pressed portions of the upper wall 5 and the lower wall 6 of the hinge body 1 are plastically deformed so as to bulge inward, and the bird intrusion prevention member 2 is clamped from above and below, and accordingly, the bird intrusion prevention member 2 is fixed to the hinge body 1.

[0013] Figs. 6 and 7 show a fourth embodiment of the hinge of the present invention. The bird intrusion prevention member 2 is formed of an aluminum profile and has a cross-sectional X-shaped portion 22 located on the diagonal of the hollow portion 12 of the hinge body 1 as shown in Fig. 6(a), and the tip portions of the respective radially extending sides thereof are in contact with the corner portions of the hollow portion 12 of the hinge body 1 respectively. As shown in Fig. 6, for the armband of the present embodiment, the bird intrusion prevention member 2 is inserted into the hollow portion 12 from the mouth of the armband body 1, and pressed from above and below by a press 17 to be caulked. At this time, as shown in Fig. 7(a), by pressing through the pressing portion 22 with a pointed tip, as shown in Fig. 7(b), the pressed portions of the upper wall 5 and the lower wall 6 of the armband body 1 are plastically deformed so as to bulge inward, and the bird intrusion prevention member 2 is clamped from above and below. Accordingly, the bird intrusion prevention member 2 is fixed to the armband body 1. The bird intrusion prevention member 2 has a cross-sectional X-shaped portion 22, and the tip portions of the respective sides of the X-shaped portion 22 abut against the corner portions of the hollow portion 12 of the armband body 1, respectively, so that the posture of the bird intrusion prevention member 2 is stabilized when inserted into the hollow portion 12 of the armband body 1, and thus caulking fixation can be efficiently performed.

[0014] Fig. 8 shows a fifth embodiment of the armband of the present invention. The bird intrusion prevention member 2 is provided with fin pieces 23 between the diagonal pieces of the X-shaped portion 22 in addition to the cross-sectional X-shaped portion 22 similar to the fourth embodiment. A gap 24 is provided between the tip of each fin piece 23 and the armband body 1. The armband of the present embodiment has a cross-sectional X-shaped portion 22 in the bird intrusion prevention member 2, and the tip portions of the respective sides of the X-shaped portion 22 abut against the corner portions of the hollow portion 12 of the armband body 1, respectively. Thus, similar to the fourth embodiment, the posture of the bird intrusion prevention member 2 is stabilized when inserted into the hollow portion 12 of the armband body 1, and caulking fixation can be efficiently performed. Further, since fin pieces 23 are provided between the diagonal pieces of the X-shaped portion 22, the hollow portion 12 of the armband body 1 is partitioned more finely by the bird intrusion prevention member 2. Therefore, even if the cross-section of the armband body 1 becomes larger, bird intrusion can be prevented.

[0015] As described above, the present armband (first and second embodiments) includes an armband body 1 and a bird intrusion prevention member 2. The armband body 1 is formed of an aluminum profile and has a locked portion 3 of the bird intrusion prevention member 2 at the longitudinal end. The bird intrusion prevention member 2 has locking portions 4 provided at both ends elastically locked to the locked portion 3 from the inside or outside of the armband body 1 to be fixed to the armband body 1. Therefore, bird nesting can be prevented. The bird intrusion prevention member 2 can be easily attached without using tools or the like, and there is no worry of coming off. Also, in this arm guard (first and second embodiments), since the arm guard body 1 is formed of an aluminum profile, it is lighter and easier to handle than the conventional steel one. Also, because it is made of an aluminum profile, it has excellent weather resistance, so maintenance costs can be reduced and it is also advantageous in terms of cost. Since the engaged portion 3 of the arm guard body 1 is formed in a slit shape, the bird intrusion prevention member 2 can be securely attached, and it can be easily formed by pressing.

[0016] This arm guard (third to fourth embodiments) includes an arm guard body 1 and a bird intrusion prevention member 2. The arm guard body 1 is formed of an aluminum profile, and the bird intrusion prevention member 2 is inserted into the hollow portion 12 from the end of the arm guard body 1 and caulked from the periphery to be fixed to the arm guard body 1, so that bird nesting can be prevented. The bird intrusion prevention member 2 can be easily attached simply by inserting it into the hollow portion 12 of the arm guard body 1 and caulking it from the periphery, and there is no worry of it coming off. Also, in this arm guard (third to fourth embodiments), since the arm guard body 1 is formed of an aluminum profile, it is lighter and easier to handle than the conventional steel one. Also, because it is made of an aluminum profile, it has excellent weather resistance, so maintenance costs can be reduced and it is also advantageous in terms of cost. In the arm guard of the third embodiment, since the bird intrusion prevention member 2 is in a plate shape, the bird intrusion prevention member 2 can be manufactured at low cost. In the arm guards of the fourth and fifth embodiments, the bird intrusion prevention member 2 has a cross-sectional X-shaped portion 22, and the tip portions of each side of the X-shaped portion 22 abut against the corner portions of the hollow portion 12 of the arm guard body 1 respectively, so that the posture of the bird intrusion prevention member 2 is stabilized when it is inserted into the hollow portion 12 of the arm guard body 1, and thus caulking-based fixing can be performed efficiently.

[0017] The present invention is not limited to the embodiments described above. The cross-sectional shape of the arm guard body may be a rectangle, a trapezoid, or the like. The shape and material of the bird intrusion prevention member can be changed as appropriate. The utility poles include power poles and telecommunication poles. The use of the arm guard of the present invention is not particularly limited, and in addition to those for installing electric wires and cables, it may also be for attaching antennas, road signs, etc.
