BLOW-IN REFRAINER
Document Type and Number:
WIPO Patent Application WO/2023/149480
Kind Code:
A1
Abstract:
The present invention refrains litters such as fallen leaves from being blown into predetermined premises. A blow-in refrainer includes a base and a plurality of stopper pieces. The base is shaped like an elongate plate disposed on a floor surface and extending in a first direction. The plurality of stopper pieces are provided on an upper surface of the base in juxtaposition in the first direction. Each of the stopper pieces is shaped like a flat plate that protrudes upward from the upper surface of the base and that extends along the first direction and that is elastically deformable. This allows the blow-in refrainer to recover even when trodden on by a vehicle or the like while refraining entry of litters and the like.
