It contacts the head 55 of the releasing means 50. The inner surface 75 of the front wall 72 of the cover member 70 is in sliding contact with the guide protrusions 28 a and 28 b provided on the front surface 3 of the case 2, and does not contact the front surface 3 of the case 2.
The release member 50 is covered by the cover member 70,
It is invisible. A guide protrusion 73a is formed on the inner surface of the left wall 73 of the cover member 70, and a guide protrusion 74a is formed on the inner surface of the right wall 74, while a guide recess 5a for guiding the guide protrusion 73a is provided on the left surface 5 of the case 2. Two
A guide concave portion 6a for guiding the guide protrusion 74a may be provided on the right surface 6 of the above to restrict the movement range of the case 2 (see FIG. 15).

When the door D is opened and the case 2 is the stopper device 8
19A, the metal stopper member 82 is pulled up by the magnetic force of the magnets 65 and 66 in the case 2, and the tip 88 of the stopper member 82 is moved to the lower surface 8 of the case 2 as shown in FIG. Abut. Locking protrusion 36
Since the inclined surface 37 is formed at the front part of FIG.
As shown in FIG. 19B, the tip 88 of the stopper member 82 slides along the inclined surface 37, and comes into contact with the lower surface 8 between the locking projection 36 and the convex portion 35, as shown in FIG. 19C.

Even if the door D is to be opened, the state shown in FIG.
As shown in (d), since the tip 88 of the stopper member 82 is locked to the convex portion 35, the door D cannot be opened.
On the contrary, when the door D is to be closed, as shown in FIG. 19 (e), the engaging edge portion 85 of the stopper member 82 causes the engaging protrusion 3 to move.
Since it is locked in the locking recess 38 of 6, the door D cannot be closed. In this way, when the case 2 of the door D is located above the stopper device 80, the metal stopper member 8
2 is pulled up and comes into contact with the lower surface 8, is sandwiched between the locking projection 36 and the convex portion 35, and is held in the state in which the door D is opened, and this series of operations is all automatically performed. Reliable and hassle free of manual labor.

When the cover member 70 is pushed down to close the door D, the pressing shaft 51 moves downward against the elasticity of the elastic member 52, and the lower portion of the pressing shaft 51 is formed in the opening 33 formed on the lower surface 8. Protruding from the end 88 of the stopper member 82.
Move downward. As shown in FIG. 19F, the engaging edge portion 85 of the stopper member 82 is pushed down to a position where it does not engage with the engaging recess 38 of the engaging protrusion 36, and the contact of the stopper member 82 with the lower surface 8 is released. It When the door D is closed, as shown in FIG. 9 (g), the stopper member 82
Since the locking edge portion 85 is not locked in the locking concave portion 38 of the locking projection 36, it is separated from the stopper device 80.

As described above, in the door stopper device 1, when the case 2 of the door D is positioned above the stopper device 80, the magnets 65 and 66 in the case 2 pull up the metallic stopper member 82 to move the stopper member 82. The tip 88 contacts the lower surface 8 of the case 2. Even if the door D is to be opened, the tip 88 of the stopper member 82 is locked to the convex portion 35 of the case 2, so that the door D cannot be opened. On the contrary, when the door D is to be closed, the locking edge portion 85 of the stopper member 82 is locked in the locking concave portion 38 of the locking projection 36, so that the door D cannot be closed. As described above, when the door D is located above the stopper device 80, opening / closing is automatically restricted.

When the pressing shaft 51 is pushed down against the elasticity of the elastic member 52, the lower part of the pressing shaft 51 is stopped by the stopper member 82.
Of the stopper member 82 is released from the contact with the lower surface 8 of the stopper member 82, and the locking edge portion 85 of the stopper member 82 is no longer locked in the locking recess 38 of the locking projection 36. Can be closed. in this way,
The door D is held in the open state by the stopper device 80, and in order to release this holding, it is sufficient to push down the cover member 70, that is, the pressing shaft 51, without forcibly bending the legs and bending the waist. It can be easily done by just stepping on the foot while standing.

Since the magnets 65 and 66 are housed in the case 2 and the magnets 65 and 66 are not exposed, the door stop device 1 can be improved in appearance and dust can enter the case 2. Can be prevented. Further, the stopper member 82 contacts the lower surface 8 of the case 2 and the magnet 6
Since there is no direct contact with the magnets 5, 66, the metallic noise generated by the impact of the direct contact, the damage of the magnets 65, 66,
It is possible to prevent damage to the stopper member 82, abrasion of the stopper member 82 and the magnets 65 and 66 due to the stopper member 82 slidingly contacting the magnets 65 and 66, and generation of rust due to scratches, which enables long-term use. .
