2. Description of the Related Art A hinge 16 is provided near a side edge of a door 1 on a door frame.
2. Description of the Related Art A door of a type (hereinafter, referred to as a "sliding door type") which is mounted on a shaft via a shaft or the like and which is opened and closed by pushing and pulling a door with a shaft mounting portion as a base end is widely used.

In the case of the hinged door, if no gap is provided between the lower end of the door and the floor of the building, the lower end of the door may be opened or closed each time the door is opened or closed due to the phenomenon of falling with time. End up rubbing the floor.

Therefore, in most cases, a design is made so that a gap L is formed between the lower end of the door 1 and the floor surface 20, and air is circulated from the gap to hinder the shielding inside and outside the door. (See FIG. 8).

In view of the above, as means for securing the lower end of the door 1, a side stile of the door frame is formed at the lower end of the door frame 2 or a door stop member 21 is provided on the floor of the building. Or the like was erected (see FIG. 9).

[0006]

In the case where the side stile and the door stop member of the door frame are formed on the floor surface as described above, when passing through the door portion, a person passing through the door stall or the door stop. In hospitals, nursing homes, nursing homes, etc. where there are many opportunities to use wheelchairs and stretchers, when wheelchairs, stretchers, etc. pass, the steps are hindered by steps, There were problems such as receiving a large shock for overcoming.

According to the present invention, there is provided a door which can completely close a gap near the door when the door is closed without providing any rising member on the floor surface, thereby improving the shielding property of the door portion. It is intended to provide a gap closing device.

[0008]

A means for solving the problems of the present invention is a device for closing a gap between doors which is mounted near a lower end of a door of a hinged door type. A slide bar for detection is attached to the base member so as to be horizontally movable and substantially parallel to the lower end surface of the door, and a return spring for constantly biasing the slide bar toward the opening / closing base end side of the door is provided on the slide bar. At a predetermined position, the tip of the slide bar slightly protrudes outward from the door-side end surface located at the door opening / closing base end side, and the rolling bar is positioned eccentrically from the center of the long plate-shaped rolling bar. A pivot portion is formed, the pivot portion is pivotally attached to the base member, and a short end of the rolling rod on the side shorter than the pivot portion is pivotally attached to one end of the laterally movable rod; The other end of the shaft is axially attached to the slide bar, and is longer than the pivot portion of the rolling rod. A long end of the rolling rod is locked in a horizontally long hole of a bracket member provided at an upper portion of the vertical sliding member, and a closing member is attached to a lower portion of the vertical sliding member. Device.

[0009]

According to the present invention, the floor near the target door is formed as a flat surface without any irregularities, so that when the door is opened, there is no adverse effect on the movement of the wheelchair or the stretcher, and the door is not damaged. When the slide bar is closed, the tip of the slide bar comes into contact with the inside corresponding surface of the door frame, and the pressing force transmitted from this corresponding surface pushes the slide bar against the elastic force of the return spring and moves laterally. The laterally movable rod also laterally moves with the lateral movement.

[0010] When the laterally movable rod moves laterally, the short end of the rolling rod pivotally attached to one end of the laterally movable rod is pulled in the direction of movement of the slide bar (obliquely upward to the right in FIGS. 3 to 6). Can be

At this time, since the pivot of the rolling rod is pivotally attached to the base member, the rolling rod rolls clockwise in FIGS. 3 to 6 around the pivot, and the long end of the rolling rod is formed. The part is pushed with a large moving width in a direction opposite to the moving direction of the slide bar (obliquely lower left in FIGS. 3 to 6),
Finally, the upper and lower sliding members are extruded below the base member,
The closing member attached to the vertical sliding member closes the gap between the doors.

The pivot portion of the rolling rod having a long plate shape is formed at a position eccentric from the center, and the pivot portion is pivotally attached to the base member. Despite the small movement width, the movement width of the long end of the rolling rod can be secured large, so that the vertical sliding width of the vertical sliding member also increases. In this way, it is possible to reliably close the gap at the lower end of the door.

[0013]

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto.

According to the present invention, a door closing device is provided near the lower end of a hinged door, and the mounting is completed by directly mounting the base member 4 of the present device to the door 1. Of course, it is also possible to incorporate the base member 4 into the door 1 so that both are integrally used.

First, the slide bar 3 for detecting the contact state between the door 1 and the door frame 2 (ie, the closed state of the door) is substantially parallel to the lower end surface of the door 1 so as to be horizontally movable. It is attached to the base member 4.

Although most of the slide bar 3 is accommodated in the base member 4, its tip 3 a is disposed so as to slightly project outward from the side surfaces of the base member 4 and the door 1.

The front end 3a is brought into contact with the corresponding surface 2 immediately before the door 1 is closed, that is, immediately before the opening / closing base side surface 1a of the door 1 contacts the corresponding surface 2a of the door frame 2 (just before the door is closed).
a, and the slide bar 3 is brought into contact with
It is pressed in the direction opposite to the opening / closing base end side of the door by the protruding width, and moves in parallel in that direction.

Here, a return spring 5 which constantly urges the slide bar toward the opening / closing base end side of the door is attached to the slide bar 3 at a predetermined position. When pushed in at 2a, the slide bar 3 performs the above-described parallel movement against the urging force of the return spring 5.

Next, when the slide bar 3 is slid rightward in FIGS. 3 to 6, the other end 6b of the horizontally movable rod 6 is axially attached to the slide bar 3, so that the horizontally movable rod 6 is also moved rightward. Pulled.

As a result, the short end 7a of the rolling rod 7, which is pivotally mounted on one end 6a of the horizontally movable rod 6, is also pulled in the same direction as the parallel movement direction of the slide bar. Further, since the pivot portion 8 of the rolling rod 7 is pivotally attached to the base member 4,
Will roll clockwise about the pivot 8, and the short end 7a will be pulled obliquely upward and to the right in FIGS.

For this reason, the long end 7b located in the opposite direction to the pivot 8 when viewed from the short end 7a is inevitably rolled obliquely downward and left in FIGS.

Here, the rolling rod 7 has a long plate shape, and the pivot 8
Are formed at the eccentric position, the length of the short end 7a is short, and the length of the long end 7b is long. There is a feature that even if the movement width is small, the movement width on the long end 7b side is large.

When the long end 7b of the rolling rod 7 rolls as described above, the pin 9 protruding from the long end 7b is inserted into the horizontally long hole 12 of the bracket member 11 provided above the vertical sliding member 10. , The vertical sliding member 10 slides vertically within the base member 4.

The upper and lower sliding members 10 have a downward U-shaped cross section, and a natural rubber having appropriate flexibility
The closing member 13 made of synthetic rubber, synthetic resin or the like is attached so as to be integrated. That is, the upper and lower sliding members 10
It has a function of sliding up and down while supporting the closing member 13.

The closing member 1 made of silicon rubber or the like
When the space portion 14 is formed inside the space 3, the whole structure is rich in flexibility and more preferable for closing the gap L.

Next, a case where a closed door is opened will be described. When the knob 15 of the door 1 is pushed and turned in the state of FIG. 4, the opening / closing base side surface 1 a of the door 1 becomes the corresponding surface 2 a of the door frame 2.
You will be away from As a result, the tip 3a of the slide bar 3 pressed by the corresponding surface 2a is released, so that the slide bar returns to the state shown in FIG. 3 by the urging force of the return spring 5, and thereafter moves up and down in the reverse order to the above description. Sliding member 10
Is returned into the base member 4.

Therefore, when the door 1 is opened and closed, the opening / closing member 13 is separated from the floor and stored in the base member 4.
The bottom of the door does not rub against the floor.

[0028]

Thus, according to the present invention, when the door is closed, the gap at the lower end of the door can be completely closed by the closing member, so that the door is excellent in soundproofing, dustproofing, airtightness and opening the door. Immediately before, since the closing member rises with the vertical sliding member 10 and is stored in the lower part of the door, there is a feature that the floor rubbing phenomenon does not occur.

Of course, since no disturbing irregularities are formed on the floor surface, there is an effect that passage through the door portion is extremely excellent in safety and the like.
