The mounting portion 3 is fixed to the door 1 with a fixing screw 3a.

A central portion in the vertical direction of the mounting portion 3 is formed into a semicylindrical insertion portion 4, and a pressure adjusting rod 5 and a winding spring 5a are inserted into the insertion portion 4. The lower end side of the pressure adjusting rod 5 is formed in a pointed shape, and one end of a winding spring 5a is fixed to a position of an intermediate portion thereof. The winding spring 5a is urged upward to be vertically adjustable. Is held.

The pressure adjusting rod 5 is fixed at a desired position in the vertical direction by an adjusting screw 5b provided on the upper side of the insertion portion 4.

On the other hand, the elastic body 6 is a floor surface F on the lower end side of the door 1.
It is placed on top. The elastic body 6 is formed of a wedge-shaped rubber, and a pressing ball 6b is rotatably mounted in a cylindrical insertion portion 6a formed in the inner plane direction.

A gap 6c is formed on the upper surface side of the insertion portion 6a. The lower end of the pressure adjusting rod 5 enters through the gap 6c and can press the pressing ball 6b.

In the above-mentioned structure, in order to hold the door 1 open to a desired degree of opening against the force of the spring, the door 1 is opened.
Open the inside of the opening 1a from the lower end side of the door 1 and the floor surface F.
While arranging the elastic body 6 in a wedge shape in the gap S between and while moving the pressing adjustment rod 5 downward, and pushing the pressing ball 6b by pushing the lower end of the rod 5 into the insertion portion 6a through the gap 6c, The pressing ball 6b presses the elastic body 6 and the elastic body 6 bends and comes into close contact with the floor surface F. When the pressing adjusting rod 5 is fixed by the adjusting screw 5b in this state, the door 2 is held at a desired opening degree.

In this way, since the pressure adjusting rod 5 and the elastic body 6 for holding the opening of the door 1 are arranged at the lower end side of the door 1, not only do not disturb the entry and exit of people, but also the pressing force. The elastic body 6 is bent by the pressing of the adjusting rod 5 and the floor surface F
Since it is closely attached to the door 1, the fixing force is strong, and the door 1 is not easily closed due to the urging force of the spring in the closing direction of the door 1, wind pressure, contact of the door 1 with a person or the like.

FIG. 4 is a side view of the second embodiment. In this embodiment, the pressure adjusting rod 5 and the elastic body 6 are rotatably integrated.

That is, the tip of the pressure adjusting rod 5 and the elastic body 6
The pressing ball 6b embedded in the above is connected, and the elastic body 6 rotates up and down with the pressing ball 6b as the center of rotation.

Since it can be moved from the state of entering into the gap S between the lower part of the floor and the floor surface F in a wedge shape (dashed line) to the state of parallel to the surface of the door 1 (solid line), it is an obstacle when opening and closing the door 1. Can be stored without having to.

Further, FIG. 5 is a side view of the third embodiment. In this case, a magnet 3A is provided on the mounting surface side of the mounting portion 3. In the third embodiment, when the door 1 is made of iron, it can be attached to and detached from the door 1, so that it can be easily attached and detached. Further, when the pressure adjusting rod 5 is made of iron, the magnet 3A pulls the pressure adjusting rod 5 toward the door 1 and integrates it with the door 1. Therefore, the pressing force of the pressure adjusting rod 5 becomes reliable, and the elastic body 6 is secured. It can be firmly brought into close contact with the floor surface F, so that even if there is a biasing force of the spring in the closing direction of the door 1, wind pressure, contact of a person with the door 1, etc., the door 1 is further prevented from being closed and is in an open state. Can be held.

In the above embodiment, the door 1 is provided with the spring (not shown) for urging it in the closing direction, but it is needless to say that the door 1 can be held in the open state even if it is not provided. Yes.

[0023]

As is apparent from the above description, according to the door open-holding device of the present invention, the door is held open by the pressure adjusting rod and the contact portion arranged on the lower end side of the door. The door can be held open without interfering with the entrance and exit of the door, etc., and the pressure adjustment rod flexes the contact part to adhere to the floor surface and the fixing force increases, so wind pressure, contact with people's door, etc. Even if there is, it can be prevented from easily closing. In addition, since the elastic body is integrally formed on the tip of the pressure adjusting rod so as to be freely rotatable, the elastic body can be housed integrally with the pressure adjusting rod on the surface of the door.
It can be stored compactly without disturbing the opening and closing of the door. Further, the elastic body formed in the shape of a wedge not only allows the elastic body to be easily inserted between the door and the floor surface, but can also increase the fixing force. In addition, since the mounting portion made of a magnet can be attached to and detached from the iron door, it can be easily attached and detached. Further, when the pressure adjusting rod is made of iron, the magnet of the mounting part pulls the pressure adjusting rod toward the door side and integrates it with the door, and the pressing force of the pressure adjusting rod is large, so the elastic body is firmly attached to the floor surface. The door can be reliably held in the open state.
