DOOR STOPPER

PROBLEM TO BE SOLVED: To improve a function by holding a door in a desired position by making an elastically deformable sphere bite in between a closed door and a floor surface while deforming/rotating the sphere. SOLUTION: A sphere is made unrollable by lowering the center of gravity of the whole by positioning a weight in the lower part of the sphere by constituting a stopper 1 by sealing, for example, a weight such as water and air in an elastic hollow sphere composed of rubber. Therefore, when the stopper 1 is placed in a desired position on a floor 6 on the side of an opening door 5, the position is held. Next, when the door 5 is moved in the door closing direction, the stopper 1 is deformed by entering between the door 5 and the floor 6 while performing deformation/rotation to hold the door 5 in an opening state in the position by pressing the door 5 by elasticity. When trying to strongly close the door 5, the stopper 1 slips out to the opposite side by passing under the door 5. When the door 5 is opened, the door 5 is similarly held. Therefore, the door can be easily held without damaging the door and a floor surface.
