Description

  The present invention relates to a bird damage prevention device that can prevent a bird from stopping on an electric wire or the like.

The conventional bird harm prevention device has the same axial center and two or more ring bodies for passing electric wires and the like, and is integrally formed with these ring bodies, and outside the peripheral surfaces of these ring bodies. A connecting portion that connects each ring body, and an arm portion that is provided at a position symmetrical to the connecting portion with respect to the axial center of the ring body and that is formed integrally with the ring body. The arm portions provided on the ring bodies located at both ends are provided with their tips extending to positions that are shorter than the distance between these ring bodies, and in the vicinity of the tips of the arm portions. Is configured with a magnet fixed thereto.

For this reason, when it is attached to an electric wire, etc., the closing ring must be fixed with bolts, which is dangerous and troublesome at work in high places, and the closing ring opens only about 90 degrees of the cylinder. Therefore, the work of inserting an electric wire or the like into the inside is difficult, and there is a drawback that the electric wire or the like cannot be inserted into the ring if the diameter of the electric wire or the like is large.
JP 2000-201612 A

    In view of the above-described conventional drawbacks, the present invention can be easily attached to an electric wire or the like without using a tool, and can be attached to an electric wire or the like having substantially the same diameter as the opening. The purpose is to provide harm prevention equipment.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention provides a bar member, a plate-like thread attachment piece formed so as to protrude upward from the upper part of at least both ends of the bar member, and the thread attachment pieces at least at both ends. A pair of support bars attached to the bar and preventing a bird from resting on the bar member, and projecting downward from the lower portions of both end portions of the bar member, and having a semicircular arc-shaped support portion formed at the lower end portion And a semicircular arc-shaped support portion formed by inserting an electric wire or the like into the semicircular arc support portions of the pair of support bars and then engaging with the support portions in a detachable manner. The bird damage prevention tool is constituted by a pair of cover bodies provided with weights via bar members in the lower part.

  As is clear from the above description, the present invention has the following effects.

(1) A bar member, a plate-like thread attachment piece formed so as to protrude upward from the upper part of at least both ends of the bar member, and the bird attached to the thread attachment piece at least at both ends A pair of support bars that protrude downward from the lower portions of both ends of the bar member and have a semicircular arc-shaped support portion formed at the lower end, and a pair of support bars After inserting an electric wire or the like into the semicircular arc-shaped support part, the upper part attached via the engaging means for detachably engaging with the support part is formed with the semicircular arc-shaped support part, and the lower part via the bar member Since it is composed of a pair of cover bodies provided with weights, it can be attached by positioning the electric wires or the like within the support portions of the pair of support bars and engaging the pair of cover bodies with the engaging means. .
Therefore, compared with the conventional screwing operation of the bolt, it can be attached by a safe and simple operation.

(2) According to the above (1), since the thread is attached to the upper thread attachment piece, even if the bird tries to rest on the bar member, it can be efficiently prevented from being interrupted by the thread and resting. .

(3) By (1) above, the bar member can be rotated around the electric wire to be attached, and the thread can be positioned at the upper part by the weight of the pair of cover bodies at normal times, ensuring bird's rest In addition to being able to prevent, when snow is attached, it rotates when the weight balance is lost, and the attached snow can be dropped.

(4) According to the above (1), the support portions of the pair of support bars are formed in a semicircular arc shape. Therefore, even if an electric wire having a size close to the diameter of the support portion is inserted into the support portion, A pair of cover bodies can be attached to the support bar.
Therefore, the range of the thickness of the electric wire etc. which can be attached to an electric wire etc. can be expanded.

(5) Claim 2 can also use the bar member which can obtain the same effect as said (1)-(4), and is lightweight and sufficient intensity | strength can be used.

(6) In claim 3, the same effects as in the above (1) to (4) can be obtained, and even if the length is relatively long, the same effect can be surely obtained by the thread attaching piece and the support part at the center. Can be done.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.
