Description

  The present invention relates to a door knob that can be easily replaced with one touch.

  Conventionally, doors and knobs are fixed to the doors with screws, etc., so that they can be replaced when the doors or knobs are damaged or severely soiled, but generally they are almost never replaced. It is fixed to the door.

  On the other hand, there is a technique in which the opening / closing member can be easily opened / closed by being easily detached from the opening / closing member and allowing the door / knob to be retrofitted to the opening / closing member without contaminating the mounted surface. This technique includes a suction cup main body that can be adsorbed to a mounting surface of an opening / closing member, and a knob member that is attached to a central portion of the suction cup main body on the side opposite to the suction surface (see, for example, Patent Document 1). .)
