Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a sliding door or door installed in a front door of a building, a sliding door installed in a window sliding door, and a self-closing mechanism of the door.

[0002]

2. Description of the Related Art Conventionally, as in the invention disclosed in Japanese Patent Laid-Open No. 60-208586, "In a sliding door having an upper and lower guides and moving along the guides, the upper and lower portions of the sliding door are respectively closed in the closing direction. There is a self-closing sliding door that connects the bell to a bell with one fin. "

[0003]

However, there is a drawback in that the fin portion of the bell deteriorates and deforms during use and does not function well. Further, there is a drawback that the closing speed of the sliding door, the door and the like is constant and not smooth, and it is not easy to adjust the closing speed of the sliding door, the door and the like to be smooth. Further, the conventional self-closing sliding door has a drawback that it cannot be easily repaired if it breaks down.

Therefore, according to the present invention, the sliding door or door is automatically closed after it is opened, and even when the sliding door or door is closed, no unpleasant noise is generated from the sliding door or door, and the door is closed quietly and smoothly. It is an object of the present invention to provide a sliding door and a self-closing mechanism for a door whose closing speed can be easily adjusted.

[0005]

1 to 8 show a first embodiment of the sliding door and door self-closing mechanism of the present invention, and FIGS. 9 to 11 show a second embodiment of the sliding door and door self-closing mechanism of the present invention. 12 and 13 show a third embodiment of the sliding door and door self-closing mechanism of the present invention, and FIGS. 14 to 16 show a fourth embodiment of the sliding door and door self-closing mechanism of the present invention. Show.

FIGS. 1 to 8 show a first embodiment of a sliding door and a door self-closing mechanism according to the present invention. FIG. 1 is a front view of a first embodiment of a sliding door and a door self-closing mechanism according to the present invention. The sliding door and the door self-closing mechanism 1 of this example is a rope having left and right sliding doors 2a and 2b attached to a sliding door frame 7, a first pulley 4 and a second pulley 4a, and a chain weight 6 attached to the other end. Three
It consists of and.

Upper frame 7a, left frame 7b, right frame 7c and lower frame 7
The first pulley 4 is fixed to the upper part of the left frame 7b of the sliding door frame 7 made of d, and the second pulley 4a is fixed to the right frame 7c or the sliding door frame 7
Fix it to the wall where is attached.

Then, a rope stop 5 is attached to the upper left portion of the left sliding door 2.
One end of the rope 3 is fixed by, and a chain weight 6 is attached to the other end of the rope 3. One end is fixed to the left sliding door 2,
A rope 3 having a chain weight 6 attached to the other end is suspended on the first pulley 4 and the second pulley 4a. Reference numeral 10 is a chain weight 6
Is a storage case for storing.

FIG. 2 is a front view showing a state in which the left sliding door of the sliding door and the self-closing mechanism of the door shown in FIG. 1 are partially opened.
