The magnetic member 8 is a so-called magnetic catch that is attached to a hinged door of furniture, etc., and is attached to a magnet mounting seat 81.

The sliding end of the hanging door 1 of the magnet mounting seat 81 is pivotally connected to the magnet holding seat 64, and is rotatable within a predetermined range.

The present invention is constructed as described above, and when the hanging door 1 is opened to a desired position and the operating knob 78 is lifted upward, the operating rod 61 moves upward and the magnetic member 8 is attached to the lower surface of the fixed frame 3. Due to the suction force, the operating rod 61 does not move downward, and the hanging door 1 does not move either, so that the open position is maintained.

If you want to increase or decrease the opening size in the open state due to the above situation, move the hanging door 1 to the desired position against the suction force while keeping it in the same state. good.

Also, if you want to fully close the hanging door 1, press the operation knob 7.
When the magnet member 8 is lowered together with the operating rod 61, the end of the magnet mounting seat 81 is pivotally connected to the magnet holding seat 64 so as to be rotatable within a predetermined range. The fixed frame 3 is removed from one end side in the sliding direction.
When the magnet mounting seat 81 stops rotating and descends, the magnet member 8 also completely separates from the fixed frame 3 and returns to its original state (the state shown in FIG. 4) due to its own weight. do.

Then, the hanging door 1 is automatically closed by the automatic closing device 5.

In the embodiment, the operating portion 7 is composed of the operating knob mounting seat 73 and the operating knob 78, but the operating knob 78 may be simply held directly on the hanging door 1, or the magnetic member 8 Although the magnet is attached to the magnet holding seat 64 via the magnet mounting seat 81, it may also be pivotally connected so as to be rotatable within a predetermined range.

That is, the configurations of the magnetic member 8, the operating rod 61, the operating section 7, the way of connecting the magnetic member 8 and the operating rod 61, etc. can be changed as appropriate without departing from the gist of the present invention. mounting position,
The configuration of the automatic opening/closing device 5 can also be changed as appropriate.

[Effects] As described above, the present invention has the operating knob facing the surface of the hanging door, so it can be operated in a comfortable posture, and the magnetic member is supported by the hanging door so that it can move up and down. Therefore, by simply adhering the magnetic member to the fixed frame, the automatic closing of the hanging door can be stopped by the adsorption force of the magnet.

Furthermore, since the magnetic members are attracted and separated by moving the operating knob up and down, the fixed frame located above the hanging door and formed to support the hanging door can be used as the attraction side of the magnet. And since the fixed frame supports the hanging door, it is necessarily provided across the sliding direction of the hanging door, so the hanging door can maintain its open position even if it is in any open position. I can do it.

In addition, since a fixed frame configured to support the hanging door is used on the side where the magnetic member attracts, separate members are provided to maintain the open position according to each open position, as in the past. It is not necessary and can be manufactured at low cost.

In addition, when you want to widen or narrow the opening size of the hanging door when it is stopped, there is no need to operate the operating section each time, and you can move the hanging door to the desired position against the attraction force of the magnet. Just move it.

Furthermore, the end of the magnetic member is directly or indirectly pivotally connected to the operating rod supported by the hanging door so as to be rotatable within a predetermined range.
When separating the magnetic member from the fixed frame,
Since the parts are separated sequentially from the end side with approximately half the force of the adsorption force, even if the adsorption force of the magnetic member is too strong against the automatic closing force of the hanging door, it can be separated without feeling any resistance. It is very easy to select the magnetic member, and it is also easy to separate the magnetic members.
