Hinged door fixing apparatus for preventing hinged door from being automatically closed

A hinged door fixing apparatus comprising:

• a base fixed to a wall to come in contact with a buffer having a buffer ball at an end thereof and mounted on a hinged door when the hinged door opens, in order to prevent a doorknob or an edge of the hinged door from directly hitting against the wall when the hinged door opens;
• and
• a holder combined with the base and instantaneously and elastically holding the buffer ball when the buffer hits against the base,
• wherein the holder includes:
• holding bars spaced from each other to form a space for inserting the buffer ball therebetween;
• guides disposed respectively between the holding bars and the base, guiding the holding bars such that the space is adjusted depending on whether the buffer ball is inserted, and hinged to the base;
• and
• elastic members disposed between the guides and providing elasticity for instantaneously holding the buffer ball when the buffer ball is inserted into the space to the holding bars through the guides.

A hinged door fixing apparatus that is mounted on a wall to hold a buffer having a buffer ball at an end thereof and mounted on a hinged door to prevent a doorknob or an edge of the hinged door from directly hitting against the wall when the hinged door opens, the apparatus comprising:

• first and second holding bars vertically spaced from each other with a predetermined gap to insert the buffer ball therebetween;
• an elastic module disposed between the first and second holding bars and providing elasticity to insert and fix the buffer ball between the first and second holding bars;
• and
• support members disposed at both ends of the first and second holding bars so that the gap between the first and second holding bars is adjusted by the elastic module,
• wherein the support members each have:
• a first support plate having a first cam groove in which a first cam follower coupled to an end of the first holding bar is inserted;
• and
• a second support plate having a second cam groove that has a symmetric structure to the first cam groove and in which a second cam follower coupled to an end of the second holding bar is inserted.

A hinged door fixing apparatus that is mounted on a wall to hold a buffer having a buffer ball at an end thereof and mounted on a hinged door, which opens and closes an internal space with a window and slams shut due to wind flowing inside through the window, in order to prevent a doorknob or an edge of the hinged door from directly hitting against the wall when the hinged door opens, and that keeps the hinged door open to prevent the hinged door from slamming shut by wind flowing between the wall and the open hinged door from the wind, the apparatus comprising:

• a housing plate having a receiving groove defined by a bottom and sides and having an inlet formed through the bottom to insert and pull out the buffer ball;
• a pair of long rollers disposed to face each other at the inlet in the receiving groove to hold the buffer ball that is inserted and pulled out;
• roller support members respectively coupled to and covering both ends of the rollers such that the rollers can rotate in the receiving groove;
• and
• elastic members providing elasticity to the roller support members between the roller support members and inner sides of the receiving groove,
• wherein the roller supports are in close contact with inner surfaces of facing side of the receiving groove and are guided when the buffer balls is inserted and pulled out through the inlet,
• the housing plate includes stoppers protruding from the bottom, inside the roller support members, to stop the roller support members such that the rollers are maintained with a predetermined gap therebetween in the receiving groove,
• the housing plate has guide grooves for guiding the elastic members on the bottom, and
• the apparatus further includes a cover plate combined with the housing plate to cover the receiving groove.
