Description

[Detailed Description of the Invention] The present invention relates to a swinging door that is attached to a door frame so that the door can be opened and closed.

A swing door has a structure in which one vertical stile of the door is rotatably attached to one side of the door frame using a hinge, etc., so the door is supported on a cantilever, and the weight of the door is reduced by long-term use. This causes the door body to sag and interfere with the door frame, making it difficult to open and close the door, or causing problems such as the door not closing.

In addition, dirt tends to accumulate in the corners between the vertical frame and the bottom frame of the door frame, that is, the lower corners, and when removing the dirt from the indoor side to the outdoor side, dirt accumulates in the lower corners. It is difficult and undesirable to remove the dust accumulated in the lower corner.

This invention was developed in view of the above circumstances, and its purpose is to prevent interference between the door and the door frame when opening and closing the door due to the door sagging, and also to prevent dirt accumulated in the lower corners of the door frame. To provide a swinging door that allows the user to easily take out the door.

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

Figure 1 is a front view of the swinging door, and the door frame A is the upper frame 1,
A lower frame 2 and a pair of vertical frames 3, 3 are framed in a rectangular shape, and a middle crosspiece 4 is attached between the pair of vertical frames 3, 3 to form a transom part 5 and a door frame part 6.
It is an expression of.

Door B has an upper stile 7, a lower stile 8, and a pair of vertical frames 9, 9 framed in a rectangular shape, and a panel 10 is attached inside the frame.One vertical frame 9 is attached to the door frame A. Attach the door B to one vertical frame 3 via the hinge 11, and attach the door B to the door frame part 6 of the door frame A.
It can be rotated freely.

The pair of vertical frames 3, 3 are attached to the frame C, and the vertical airtight members 12, 12 in contact with the pair of vertical frames 9, 9 of the door B are attached.

Reference numeral 13 denotes a latch lock provided on the other vertical frame 9, which is engaged with a lock 14 provided on the other vertical frame 3 to lock and fix the door B to the door frame A in a closed state.

The lower frame 2 has an outdoor side wall 2a, a connecting wall 2b, a rising wall 2c, an upper wall 2d, and an indoor side wall 2e to form a staircase shape with the outdoor side lowered, and the rising wall 2c has a groove 15. A lower horizontal airtight material 16 is attached to the groove 15, and a groove 17 is formed which is continuous to the connecting wall 2b by the connecting wall 2b, the rising wall 2c, and the groove 15.

20 is a door stop member attached to the lower corner of the vertical frame 3 and the lower frame 2 on the side having the latch lock, and includes a locking piece 21 that fits in the groove 17, the connecting wall 2b and the vertical frame. The upper surface of the main body 22 is an inclined surface 22' that slopes downward toward the outdoor side.

That is, from the partition part 22a in contact with the inner part of the lower corner of the main body 22 to the outdoor side edge part 22b and the inner side edge part 2.
2c, and the height of the partition portion 22a is
The height is such that it contacts the lower surface 8a of the lower stile when the door B is installed in the correct state (not hanging down).

When the door B is closed, the lower surface 8a of the lower stile is successively pushed up along the inclined surface 22' of the main body 22 of the door stop member 20, and is pushed up and supported in the correct state when the door B is closed.

Therefore, even if the door B is used for a long period of time, it is possible to prevent the door B from sagging.
Since the door can be pushed up along the inclined surface 22' of the door and held in the correct state, door frame A and door B will not interfere with each other, making it difficult to open and close the door, and furthermore, door B will not be unable to close. .

Further, since the door stop member 20 is attached to the lower corner portions of the vertical frame 3 and the lower frame 2, it is possible to prevent dirt from accumulating in the lower corner portions and to easily throw out the accumulated dirt. This makes it easier to remove trash from inside the room.

In addition, as shown in FIG. 6, the main body partition part 22a of the door stop member 20 is a horizontal surface on which the lower stile lower surface 8a of the door B rests when the door B is closed, supporting the door B in the correct state in a stable state. It may be configured to do so.

Further, the door stop member 20 has a locking piece 21 as shown in FIG.
The cover piece 23 that covers the main body 22 and the lower frame outdoor side wall 2a is fixed, and the upper surface 23a of the cover piece 23 is attached to the inclined surface 2 of the main body 22.
2' and a downwardly curved curved surface,
As shown in FIG. 8, the lower surface 30a of the connecting piece 30 that connects the lower stile 8 and the vertical stile 9 may be formed into a slope that slopes upward toward the room.

In this way, when closing door B, the connecting piece 30
Since the inclined lower surface 30a of the cover piece 23 is pushed up along the inclined upper surface 23a of the covering piece 23, even if the door B droops down considerably, the door B can be pushed up to the correct state and closed.

The present invention is as described above, and even if the door B hangs down, when the door is rotated in the closing direction, the lower end of the door is successively pushed up along the slope of the door stop member 20, so that it interferes with the door frame A. This also prevents the door B from sagging.

Moreover, even if door B were to sag, it would not become difficult to open and close, and it would not become impossible to close door B.

Further, since the door stop member 20 is provided at the lower corner, it is difficult for dirt to accumulate at the lower corner, and it can be easily removed.
