ABSTRACT:
A doorstop includes a base secured to a floor; the base containing a buffer in relation to the direction of a door panel; a magnetic member being inserted into the center of the buffer; an elastic member being disposed to the inner end of the magnetic member; the elastic member enabling the buffer to engage in reciprocal compression; and when the door is opened, a door panel contacts the doorstop; impact applied by the door panel being absorbed and offset by a coil disposed to the inner end of the buffer; and the door panel being attracted to the magnetic member to prevent possible bouncing back by the door panel.
