Further, a magnetically permeable yoke 17 and a magnet 18 supported by the yoke 17 are alternately arranged and fitted, and further, a cushioning material 19 similar to the cushioning material 16 is fitted.
Then, the side opposite to the side where the yoke 17 of the cushioning material 19 is located is brought into contact with the lower surface of the distal end portion 2b of the arm 2, and the mounting screw 20 is inserted from the mounting hole 12 into the through hole 15c and tightened, thereby attaching the stopper 3 to the arm 2 Be fixed to. then,
The cushioning members 16 and 19 are compressed and expanded by the rotation of the mounting screw 20, and are formed so as to slightly protrude outward from the outer periphery of the magnet 18 and the yoke 17. Thus, the stopper 3 and a receiving member described later constitute a silence structure that silences a collision sound at the time of contact, and also constitutes a buffer structure that attenuates the contact impact at the time of contact.

The hinged door 24 is rotatably supported on a side frame 25 by a hinge 26. And, on the upper side of the hinged door 24, one receiving member 27 can be provided.

The receiving member 27 having one door stop is shown in FIGS.
As shown in FIG. 6, a door stop 29 and a back plate 30 are provided. The door stopper 29 is made of metal, has a substantially square planar shape, and has a mounting portion 29b having several mounting holes 29a.
And a receiving portion 29 bent downward from the mounting portion 29b.
c so as to form a substantially L-shape.
A curved portion 29d corresponding to the outer periphery of the stopper 3 is provided at the center of the width of 9c. On the other hand, the back plate 30 has a resin block shape, and has a concave portion 30a corresponding to the curved portion 29d formed on one side. The back plate 30 is bonded to the door stop receiver 29 by combining the curved portion 29d and the concave portion 30a.

Next, a method of attaching the door stop 1 and the receiving member 27 will be described with reference to FIGS. For the door stop 1, the screw 50 is inserted into one of the mounting holes 4 and temporarily loosely temporarily fixed to the lower surface of the upper frame 23. Then, while the mounting hole 4 is rotated in the X direction using the mounting hole 4 as a rotation axis, the situation of the place of use is determined. Set the mounting angle arbitrarily according to. At this time, by forming a state where the curved portion 29d of the receiving member 27 is held in contact with the stopper 3 so as to be held, the mounting portion 29 of the receiving member 27 is formed.
b and the back plate 30 are brought into contact with the upper part of the opening door 24, and while the opening angle is adjusted, the mounting angle of one door stop is arbitrarily set, and at the same time, the upper side of the opening door 24 of the receiving member 27 corresponding thereto. Is set while sliding in the Y direction. Then, the door stop 1 is fastened by inserting the screw 51 into some other mounting holes 6 to 10 and tightening the screw 50 of one mounting hole 4 to fix the door stop 1 to the lower surface of the upper frame 23. As shown in FIG. 1, a state is formed in which the stopper 3 side protrudes toward the opening side of the opening door 24. On the other hand, as shown in FIG. 1, the receiving member 27 is provided with a screw 5 in the mounting hole 29a of the mounting portion 29b.
2, the receiving member 27 can be fixed to the upper surface of the door 24. When the holding of the stopper 3 and the receiving member 27 is released after the door stop 1 and the fixing of the receiving member 27 are completed, the opening and closing of the hinged door 24 becomes possible.

When the hinged door 24 is opened, as shown in FIG. 1, the receiving member 27 and the stopper 3 come into contact at an opening angle position of about 90 degrees. At that time, the cushioning materials 16 and 19 are placed before the door 18 and the magnet 18 and the yoke 17.
9, the silence structure and the cushioning structure mitigate the collision sound at the time of contact and also reduce the contact impact. When the stopper 3 comes into contact with the receiving member 27, the receiving member 27 is attracted to the magnet 18 and the yoke 17 of the stopper 3, and the contact state between the stopper 3 and the receiving member 27 is maintained. The holding of the contact state exerts a considerable holding force because the magnet 18 and the yoke 17 of the stopper 3 contact the curved portion 29d and have a large contact (adsorption) area. However, this holding force cannot withstand the normal closing operation force of the hinged door 24.

By the way, depending on the situation of the living space, the hinged door 24 can be widely opened without being obstructed by walls or furniture. In the case of such a hinged door 24,
After rotating about one mounting hole 4 as described above to set a large mounting angle, the screws 51 are inserted into the other mounting holes 7 to 11 and tightened to be fixed to the lower surface of the upper frame 23. The state shown in FIG. In this case, the other mounting holes 7 to 11
Uses five pieces as in the case shown in FIG. 1, so that one door stop can be attached without reducing the attachment strength.

In all the illustrated embodiments described above, the door stop structure of the left-opening hinged door 24 has been described. However, the present invention is not limited to the door stop structure of the left-opening hinged door 24, but arranges the other mounting holes 5 to 11 symmetrically with respect to the longitudinal straight line of the arm 2 passing through one mounting hole 4. Therefore, as shown in FIGS. 11 and 12, the present invention can be applied to the case of the right-opening hinged door 24 as well as the case of the left-opening hinged door 24.

[0038]

As described above, according to the door stop structure of the present invention, the door stop is turned around one mounting hole,
At the rotation position, the door stop is attached by one mounting hole and several other mounting holes, and the opening angle of the door is set arbitrarily. The angle can be set arbitrarily, and the cost can be reduced.

Further, since the door can be used for either the left or right door simply by changing the direction of rotation of the door stop, the cost can be further reduced.

Further, when the hinged door is opened, the stopper is received by the receiving member and is held in the open position by the catch structure, so that the hinged door can be prevented from being damaged and the hinged door can be opened without deteriorating the safety of the feet. Position can be maintained.

Further, according to the door stop mounting method of the present invention, it is possible to easily install the door stop without any skill while simultaneously adjusting the opening angle of the hinged door and adjusting the installation angle of the door stop. In particular, even when the door stop and the receiving member are set, it is easy to set the mounting position of the receiving member corresponding to the stopper,
