PURPOSE: A built-in type door stopper having a vertically appearing and disappearing structure is provided to convenience in use by configuring not to protrude to the outside, to have luxurious exterior and to have excellent universality capable of overcoming the height difference between the bottom and the door. CONSTITUTION: A built-in type door stopper having a vertically appearing and disappearing structure includes a built-in body(10), a cover body(20), an elevation shaft(30), an elevation spring(40), a support unit(50), a latching piece(60) and a button release unit(70). The built-in body is embedded in a door and is installed. The cover body is connected with the rear side of the built-in body. The elevation shaft elevates from the inside of the built-in body and appears and disappears from the opened lower side of the built-in body. The elevation spring gives the up and down direction elasticity to the elevation shaft. The support unit is combined with the lower part of the elevation shaft and contacts with the bottom plane when protruding. The latching piece is located inside of the built-in body and maintains the lowering state of the elevation shaft. The button release unit arbitrarily moves the latching piece and elevates the lowered elevation shaft with a elastic force. |
