Patent ID: 10174506

Abstract:
The present invention relates to an elastic foothold for stairs comprising: an upper plate, wherein one or more first coupling protrusions are formed on a side of a bottom surface, one or more first block insertion parts having second coupling protrusions are formed on the other side of the bottom surface, and a first anti-slip part is formed on a side of a top surface; a lower plate, wherein first coupling grooves corresponding to the first coupling protrusions are formed on a side of the bottom surface so as to be male/female-coupled to a side of the upper plate, and one or more second block insertion parts having third coupling protrusions are formed on the other side of the bottom surface; one or more first blocks that are inserted and coupled to the first block insertion parts, that have second coupling grooves formed on a bottom surface so as to be male/female-coupled to the second coupling protrusions, and that have third coupling grooves formed on a top surface; one or more second blocks that are inserted and coupled to the second block insertion parts, that have fourth coupling grooves formed on a bottom surface so as to be male/female-coupled to the third coupling protrusions, and that have fifth coupling grooves formed on a top surface; and one or more first elastic members, wherein both ends are respectively fixed to the fourth coupling grooves and the fifth coupling grooves between the first blocks and the second blocks. According to the present invention, an elastic foothold for stairs that can be fixed to stairs and that minimises shock applied to feet when climbing up and down the stairs so as to be able to prevent harmful effects on joints such as knees of a walker can be provided.
