[0003]

However, the prior art has the following problems. In the conventional birds and beasts harm prevention tool, the above-mentioned protrusions are arranged quite densely because it is necessary to prevent the birds from being caught between the protrusions. Was a factor that put a load on. Further, in order to arrange the protrusions densely, it is necessary to increase the number of protrusions to be planted per unit length, so that there is a problem that it takes time and effort to plant the protrusions on the outer periphery of the tubular body.

The present invention has been made in order to solve these problems, and the purpose thereof is to reduce the number of projections and to reduce the weight as compared with the prior art, and to obtain a sufficient effect of preventing damage to birds and animals. It is to provide a preventive device for damage to birds and animals.

[0005]

In order to achieve the above object, the present invention provides a tubular body, which can be mounted on the outer periphery of a wire such as an electric wire, and an outer periphery of the tubular body. A plurality of projections, which prevents birds and animals from leaning against the wire by the projections, wherein the projections are trunks provided in a substantially centrifugal direction of the tubular body, and the trunks. And a branch portion that is provided so as to be substantially parallel to the axial direction of the tubular body.

BEST MODE FOR CARRYING OUT THE INVENTION According to the bird and beast damage preventing device of the present invention,
Since a protrusion is provided on the outer circumference of the tubular body, this protrusion becomes an obstacle for birds and small animals, making it difficult for them to get caught in the wire rod and to move on and off the wire rod. Disappear. And, in particular, since this projection has a trunk portion and a branch portion, even if this projection is installed relatively sparsely with respect to the tubular body, the branch portion becomes an obstacle between the installation positions of the projections, and The effect can be secured sufficiently. Moreover, if the protrusions are installed sparsely, the number of protrusions arranged per unit length can be reduced, so that it does not take much time to manufacture the bird and animal damage prevention device, and the trunks are arranged closely. The animal and animal harm prevention equipment is lighter than when
There is an advantage that the load on the electric wires and the like is reduced.

According to the bird and beast damage prevention device of the second aspect, since the projection is a flexible projection, it flexes easily when an external force is applied, and even if an operator touches it by hand, It does not hurt, and even if a bird or the like comes into contact with it, it will not hurt. In addition, even if the bird and beast damage prevention tool falls due to the breakage of the electric wire for some reason, the flexible projection does not damage what was at the drop position.

By the way, since the flexible projection may be stepped on by a bird or the like, in such a case, the desired effect may not be obtained with the conventional projection. In the case of toys, if the executive is stepped down,
Birds are uncomfortable and have the effect of dispersing the birds, because the branches that were facing sideways are turned upwards.

Further, according to the bird and beast damage preventing device of the third aspect, since the collar portion is provided on the outer periphery of the tubular body, the effect of preventing the small animals from coming and going is further enhanced. Also, since the flexible protrusions are projected from the outer edge of the collar portion, if a large number of flexible protrusions are integrally formed with one collar portion, only one collar portion can be attached to the tubular body. Then, the attachment of a large number of flexible protrusions is completed, and the bird and animal damage prevention device can be easily manufactured.
