Description

  In the present invention, an adsorption board having a key-like hook is adsorbed on a wall surface to suspend an object, or attached to a bottom surface of a leg portion of a chair or the like, and adsorbed to a floor surface of a bathroom or a bathtub to prevent the chair from moving. The present invention relates to a suction disk having a skid prevention function.

  Suction cups with key-like hooks are used to hang brushes directly on the walls of bathrooms and kitchens, or to attach a stand to keep frequently used items such as soap and detergent close at hand. Yes. However, heavy items such as soaps and detergents often place an excessive load on the suction disk, and the suction position of the suction disk shifts over time, or often drops at the end. Various attempts have been made to solve this problem.

  For example, in Patent Document 1, in a suction disk apparatus that holds and holds a supported member on a suction surface of a support, a second suction disk is provided on the suction surface side of the suction disk. A board device is disclosed. In patent document 2, it consists of an outer suction disk and an inner suction disk, and the inner suction disk is disposed within the outer peripheral edge of the outer suction disk, and the outer peripheral edges of the outer suction disk and the inner suction disk are substantially the same plane. There is disclosed a suction disk that is located inside and connected to each other, and configured such that both the outer suction disk and the inner suction disk are attracted to the suction surface. Furthermore, Patent Document 3 discloses a suction disk in which a plurality of small suction disks having a suction disk peripheral height lower than that of the suction disk peripheral height at the time of non-adsorption are integrally formed in the suction concave surface of the large suction disk. Has been.

As described above, suction plates having a suction plate further provided on the suction inner surface of the suction plate are well known, but these known parent-child type suction plates have an inner suction facing the same direction as the outer suction plate in the suction plate. Since the board is provided, it is difficult to prevent the skidding sufficiently when sliding in the lateral direction. When an elderly person or a person with a physical disability takes a bath, an adsorption board is adsorbed on the floor surface of the bathroom or in the bathtub so that the chair can safely sit on the floor. The appearance of a bath chair having a skid-preventing function is desired in order to make the height of the surface uniform and make it easy to enter the bathtub.
