Description

  The present invention relates to a door stopper that holds a door of a hinged door type or a sliding door type in an open state or a closed state.

  The well-known door stopper is a bar-shaped door that has a leg cap fixed to the installation part with the floor by crowning or bonding, etc., in order to keep the hinged door in the open state. There are some which can set the tension member diagonally.

  When the door is in the open state, the tension member provided with the leg cap is set so as to resist the force acting in the closing direction, and holds the door in the open state.

With known door stoppers, the strut members with leg caps can be set only in the direction against the force in the closing direction of the hinged door type door, so the force against the force in the door opening direction of the hinged door type door Does not occur and does not function as a door stopper against the force in the door opening direction.

Therefore, when trying to open the door from the outside with the door closed, a so-called crime prevention effect that makes it difficult to open the door cannot be expected.

Further, the sliding door type door has a structure in which no force can be generated against the force in either the opening direction or the closing direction.

  With the well-known door stopper, the hinged door type door can be held in the open state, but the hinged door type door is held in the closed state, so it is not possible to generate a force against the force acting in the opening direction. Therefore, there is a problem that the sliding door type door cannot be kept closed.

In addition, even if a well-known door stopper is attached to a sliding door type door, no force can be generated against the force in the opening and closing directions, and the hinged door can be in either the open or closed state. There is a problem that cannot be held.

It is an object of the present invention to solve these problems and to provide a door stopper that can be held in either the open door state, the closed door state, or both of the hinged door type door and the sliding door type door.

  In contrast to the structure in which the tension member of the well-known door stopper is set only in the direction against the force acting in the closing direction of the hinged door type door, the tension member of the present invention is the door of the hinged door type door. By adopting a structure that can be set in a direction that resists the force acting in the direction, it is possible to generate a force that resists the force acting in either direction of opening and closing of the hinged door.

  In addition, for a sliding door type door, a force that works in either direction of opening and closing of the sliding door type door by adopting a structure that can set the tension member in a direction that resists the force acting in either direction of opening and closing. It is possible to generate a force that resists the above.

  As described above, the product of the present invention sets the tension member so that the conventional door stopper generates a force that only resists the force in the closing direction of the door of the hinged door type. A structure that can be set to generate a force that resists the force solves the problem.

  With a structure that allows the tension member to be set in multiple directions, it is possible to generate a force that resists the force that acts in the opening and closing directions of the door, regardless of whether it is a sliding door type or a sliding door type door. It is possible to provide a door stopper that can be held in either an open state or a closed state, both in a door type and a sliding door type.

  The best shape of the door stopper of the present invention is that a rod-shaped beam portion provided on a mounting substrate attached to the door is provided with a rotating portion that can rotate along a plane parallel to the floor surface, and a tension member is attached to the rotating portion. An attachment portion is provided, and a tension member is attached to the attachment portion, and a leg cap set on the floor surface is installed at the tip of the tension member.

To counteract the force acting on the door, rotate the rotating part provided on the beam, direct the thrust member in the direction of the force acting on the door, and install the leg cap on the floor surface. It can be obtained by friction force generated between them.

  As described above, the embodiment of the present invention has a structure in which the direction of the tension member and the leg cap is rotated and can be freely set in the direction of the force acting on the door, thereby resisting the force acting on the door in multiple directions. It is possible to generate a force, and it is possible to provide a door stopper that can be held in an open door state or a closed door state in any door of a hinged door type or a sliding door type.

  Embodiment 1 of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of a door stopper 1 of Example 1. The door stopper 1 is provided on a mounting board 2 that can be mounted on a door, a beam part 3 provided on the mounting board, and a beam part 3.
