The stopper 9 has a connecting member 20, as shown in FIG. The connecting member 20 has a shaft shape,
A large diameter portion 20b is integrally formed at one end of the small diameter shaft portion 20a,
A shaft hole 20c is provided at the center of the shaft, and a small-diameter shaft portion 20a is provided.
Is provided with a notch 20d on the outer periphery of the upper part. The connecting member 2
A small-diameter shaft portion 20a is fitted with a high-compression-expansion cushioning material 21 such as synthetic rubber, for example, from the large-diameter portion 20b side. Are alternately arranged and fitted, and further, a cushioning material 24 similar to the cushioning material 21 is fitted.

Then, the side opposite to the side where the yoke 22 of the cushioning member 24 is located is brought into contact with the lower surface of the distal end portion 8b of the arm 8, and the mounting screw 27 is inserted through the mounting hole 18 into the shaft hole 20c and tightened. Is fixed to the arm 8.
At this time, the rotation of the mounting screw 27 causes the cushioning materials 21 and 24 to rotate.
Is compressed and expanded so as to slightly protrude outward from the outer periphery of the magnet 23 and the yoke 22. Thereby, the stopper 9 and a receiving member described later constitute a silence structure that silences a collision sound at the time of contact, and a buffer structure that attenuates the contact impact at the time of contact.

In the door stop 7 described above, the one through hole 10 is aligned with the one screw hole 3 of the base plate 2, and then, as shown in FIG. After that, the mounting angle is arbitrarily set according to the situation of the place of use while rotating about the through hole 10. Then, some other through-holes 13.15.1.
While inserting the screw 31 into each and tightening,
The door stop 7 is fixed to the base plate 2 by tightening the screw 30 of one through hole 10, and the stopper 9 side is provided so as to protrude toward the open side of the opening door 32.

The hinged door 32 is attached to a side frame 35 by a hinge 36.

The mounting position of the receiving member 37 is moved in accordance with the movement of the door stop 7.

After that, when the hinged door 32 is opened, as shown in FIG.
And the stopper 9 come into contact with each other. In this way, the door 32
Can be greatly changed from approximately 85 degrees to approximately 133 degrees.

Incidentally, in all the illustrated embodiments described above, the door stop structure of the left-hand swing door 32 has been described. However, the present invention is not limited to the door stop structure of the left-opening hinged door 32, and the other through holes 11 to 17 are symmetrical with respect to the longitudinal center axis S of the arm 8 passing through one through hole 10. Since it is arranged, as shown in FIGS. 11 and 12, it can be applied to the case of the right-handed swing door 32 as well as the case of the left-hand swing door 32.

In all the illustrated embodiments described above,
The base plate 2 is formed horizontally long, the screw holes 3 are formed in the longitudinal direction of the base plate 2, and the door stop 7 is laterally moved in the longitudinal direction of the base plate 2 and attached to the screw holes 3, thereby changing the opening angle of the hinged door 32. Configuration. However, the present invention is not limited to changing the opening angle of the hinged door 32 by laterally moving the door stop 7 in the longitudinal direction of the base plate 2 and attaching the door stop 7 to the screw hole 3. For example, the configuration shown in FIG. You can also.

That is, the base plate 2 to which the door stop 7 is attached has a plurality of other screw holes 3 formed on the same circumference around one screw hole 3 as shown in the figure. A screw (not shown) is inserted into the through hole 4 to be mounted or embedded on the lower surface of the upper frame.

When the door stop 7 is attached to the base plate 2, as described above, one through hole 10 is aligned with the center screw hole 3, and then a screw is inserted and temporarily loosely temporarily fixed. The mounting angle is arbitrarily set according to the situation of the place of use while rotating about the hole 10. Then, screws are inserted into some of the other through holes 13, 15, and 17, respectively, and tightened.
Tighten the No. 0 screw to fix it.

Then, when the opening angle of the hinged door 32 is changed later by changing the living space, the other through holes 13.
Remove screws 15 and 17. Then, the door stop 7 is turned around the one through hole 10 to change the mounting angle, and is fixed again at the turning position. Thereby, the opening angle of the hinged door 32 is, for example, from approximately 85 degrees to approximately 1 as described above.
It can be greatly changed to 33 degrees.

[0040]

As described above, according to the door stop structure of the present invention, when the opening angle of the hinged door is changed later,
Since it is only necessary to remove the door stop and attach it to another mounting hole, the opening angle of the hinged door can be changed stepwise and easily according to a change in living space.

Further, since the door stop is attached to the base plate, it is possible to secure sufficient mounting strength to withstand the impact of the hinged door, and to change the opening angle of the hinged door without leaving a scratch on the upper frame.

Further, since the horizontally long base plate is formed symmetrically along the line bisecting the length dimension, it can be used for both left and right, cost can be reduced, and attachment work can be performed regardless of the mounting direction. Can be easy.

Furthermore, the cost can be reduced because the door can be used on either the left or right door simply by changing the turning direction of the door stop.
