On both sides of the gripping plate 72, vertical plates 91, 91 are provided downward, and horizontal plates 92, 92 are provided at the lower ends of the vertical plates 91, 91. The vertical plates 91, 91 are formed at substantially the same height as the front locking plate 82 and the rear locking plate 83, and the front locking plate 82 and the rear locking plate 83 are more than the stopper plates 50 than the adjustment plates 81, 81. The substrate 51 is formed so as to be substantially thicker.

  The door stopper 1 described above is provided in a recess D1 formed at the lower end of the door D as shown in FIG. 9A (a), and the insertion hole 7a in the first case 2 as shown in FIG. 9A (b). It is fixed to the door D by inserting the attachment screw E into the door D and screwing it into the door D. As shown in FIG. 9A (c), the substrate 51 of the stopper device 50 is attached to the lower part of the interval adjusting device 70. The substrate 51 is brought into contact with the lower end (lower contact portion) 81a of the adjustment plate 81 of the distance adjusting device 70 on the upper surface thereof, and the front locking plate 82 of the distance adjusting device 70 is engaged with the locking recess 63 of the substrate 51. The locking protrusion 85 is locked, the locking protrusion 86 of the rear locking plate 83 is locked to the locking recess 65 of the substrate 51, and the engagement pins 79 of the distance adjusting device 70 are engaged with the engagement holes 61, 61 of the substrate 51. , 79 are engaged and attached to the interval adjusting device 70.

  As shown in FIG. 9A (d), the engagement plate (spacing adjusting member) of the spacing adjusting device 70 is placed on the lower surface 10a of the engaging members 11 and 12 of the second case 10 of the door stopper 1 with the substrate 51 mounted. ) 71 is brought into contact with the upper surface (upper contact portion) 71a, and the distance adjusting device 70 is slid to engage the engagement piece (engagement portion) 76 with the engagement recesses 11a and 11a of the engagement member 11. The interval adjusting device 70 can be attached to the lower surface 10 a of the second case 10.

  The second case 10 is movable in the vertical direction within the first case 2, but is fixed by the fixing screw 36, so that the fixing screw 36 is loosened to make it movable. As shown in FIG. 9B (e), when the distance adjusting device 70 is pushed down, the second case 10 is similarly pulled out downward as shown in FIG. 9B (f), and the substrate 51 is brought into contact with the floor surface F. In contact, the downward movement stops. By tightening the fixing screw 36, the second case 10 is fixed so that the first case 2 cannot move. This ensures that the distance between the magnet (magnet) 42 in the second case 10 and the floor surface F is constant regardless of the distance between the door D and the floor surface F.

  As shown in FIG. 9B (g), when the distance adjusting device 70 is held so as not to move and the door D is rotated, the door stopper 1 is moved to the lower surfaces of the engaging members 11 and 12 of the second case 10. 10a slides on the upper surface (upper contact portion) 71a of the engaging plate (spacing adjusting member) 71 of the spacing adjusting device 70, while the engaging recesses 11a, 11a of the engaging member 11 engage with the engaging piece of the spacing adjusting device 70. It disengages from the (engagement portion) 76 and disengages from the interval adjusting device 70. The substrate 51 can be fixed to the floor surface F by screwing screws 78, 78 from the notches 77, 77 of the interval adjusting device 70 into the floor surface F through the screw through holes 60 of the substrate 51.

  As shown in FIG. 9B (h), since the substrate 51 is fixed to the floor surface F by screws 78, 78, when the distance adjusting device 70 is pulled upward, it is moved forward from the locking recess 63 of the substrate 51. The locking projection 85 of the locking plate 82 is removed, the locking projection 86 of the rear locking plate 83 is removed from the locking recess 65 of the substrate 51, and the engagement pins 79, 79 are inserted from the engagement holes 61, 61 of the substrate 51. Separated and detached from the substrate 51. Thus, the board | substrate 51 can be reliably attached under the rotation track | orbit of the door stopper 1, and also the height with the magnet (magnet) 42 of the door stopper 1 can always be made constant.

  The stopper device 50 is assembled by attaching the attachment shafts 54 and 54 of the stopper plate 52 to the bearing portions 62 and 62 of the substrate 51 so as to be rotatable and attaching the cover 68 to the substrate 51. In addition, the board | substrate 51 can be mounted | worn with the space | interval adjustment apparatus 70 in the state which attached the stopper board 52 so that rotation was possible. The pair of adjustment plates 81 are arranged on both sides so as to sandwich the stopper plate 52, and the lower end (lower contact portion) 81a contacts the upper surface of the substrate 51. Therefore, the stopper plate 52 is incorporated into the substrate 51 from the beginning. But there is no problem.

  When the door D is rotated in the opening direction and the door stopper 1 moves above the stopper device 50, the stopper plate 52 is pulled upward by the magnet (magnet) 42, and the tip 55 of the stopper plate 52 is moved to the door stopper 1. The second case 10 is locked to the locking portion 16f (15f). In this state, when the operation plate 25 is operated to push the operation plate 22 against the elasticity of the snap spring 28, the tip of the lock plate 21 protrudes into the engagement opening 53 of the stopper plate 52 and engages therewith. Lock the rotation of D. Therefore, the door D is restricted from rotating in the closing direction as well as the opening direction. The lock plate 21 is positioned in this state by the elasticity of the snap spring 28. The door D is thus restricted from being opened by the door stopper 1.

  When the operation plate 25 is operated and the operation plate 22 is pulled up against the elasticity of the snap spring 28, the tip of the lock plate 21 is separated from the engagement opening 53 of the stopper plate 52, and the engagement is released. unlock. Therefore, the door D can be turned in the closing direction. The lock plate 21 is positioned in this state by the elasticity of the snap spring 28. When the door D is rotated in the closing direction, the door stopper 1 is separated from the stopper device 50, so that the stopper plate 52 returns to the original position.

  INDUSTRIAL APPLICATION This invention can be utilized for the door stopper locked in the state which opened the door to open and close.
