Abstract
A safety door stopper for use in trip, including a wedge stopper block and a coupler member. The coupler member is used to fix the wedge stopper block under a lower edge of the door board. A bottom face of the wedge stopper block is disposed with an unsmooth face. When the wedge stopper block is fixed under the lower edge of the door board, the unsmooth face is able to enlarge the frictional coefficient between the door board and the ground and enlarge the frictional force. Therefore, the resistance against the door board is increased to make it difficult to push open the door board and ensure safety in trip.
Claims1
A safety door stopper for use during travel comprising a wedge stopper block and a coupler member, the wedge stopper block having a roughed bottom face, the wedge stopper block being coupled with the coupler member, the coupler member being a substantially U-shaped member disposed on a lower edge of the door board and fixed under the lower edge of a door board with the wedge stopper block positioned between the lower edge of the door board and the ground, wherein a lateral side of the coupler member is disposed with multiple semicircular projecting rings and a slope face of the wedge stopper block is formed with multiple holes, whereby a pin member is passed through the projecting rings and inserted into the holes of the wedge stopper block so as to integrally connect the coupler member with the wedge stopper block.
