The base 53 is fixed to the floor F with screws 56, an adhesive or the like.
[0023]
The door stopper device A has the above configuration, and the locking shaft 25 is normally housed in the unlocked position, that is, in the case 2, as shown in FIG. At this time, the engagement protrusion 46 of the holding means 45 is engaged with the second engagement portion 42 of the guide groove 40, and holds the guide shaft 21.
[0024]
When the operating means 20, that is, the pressing plate 22 is pressed against the elasticity of the spring (first elastic member) 37, the guide shaft 21 is pushed down, and the locking shaft is pushed through the spring (second elastic member) 33. The 25 locking pins 26 are pushed out. As shown in FIG. 3, the engaging projection 46 of the holding means 45 is engaged with the first engaging portion 41 of the guide groove 40, and the locking shaft 25 is projected and held at the locking position.
[0025]
Further, the operating means 20, that is, the pressing plate 22 is pressed against the elasticity of the spring (first elastic member) 37, and when this pressing is released, the engaging projection 46 of the holding means 45 is moved to the first position of the guide groove 40. The guide shaft 21 and the locking shaft 25 move in the anti-locking direction by the elasticity of the spring (first elastic member) 37. As shown in FIG. 2, the engagement projection 46 of the holding means 45 engages with the second engagement portion 42 of the guide groove 40, and the locking shaft 25 is stored in the non-locking position, that is, in the case 2. Is held.
[0026]
As described above, the door stopper device A can switch the locking shaft 25 between the locked position and the non-locked position only by the pressing operation of the operating means 20, that is, the pressing plate 22. In addition, the engagement protrusion 46 of the holding member 45 rotates the guide groove 40 counterclockwise as shown in FIG. Since the locking shaft 25 slides with respect to the guide shaft 21 and is urged in the locking direction by a spring (second elastic member) 33, when the locking shaft 25 is in the locking position, When a strong force is applied to the locking shaft 25, the locking shaft 25 can slide in the anti-locking direction against a spring (second elastic member) 33, and the locking shaft 25 and the case 2 Can be prevented from being broken.
[0027]
When the base 53 of the floor-side device 50 is fixed to a predetermined position on the floor F below the door-side device 1 when the door D is opened, as shown in FIG. When D is opened, the metal stopper plate 52 rotates so that the tip is pulled up by the magnetic force of the magnet 13 in the case 2, and the tip of the metal stopper plate 52 contacts the bottom wall 8 of the case 2 and is locked. Locked by the projection 8a, the opening and closing of the door D is regulated (see FIG. 6). As described above, when the pressing plate 22 is pressed, the locking pin 26 projects to the locking position, and the locking pin 26 is locked in the locking recess 51 of the metal stopper plate 52 as shown in FIG. You. Therefore, the door D is stopped by the floor-side device 50 in an open state.
[0028]
When the pressing plate 22 is pressed again, the locking pin 26 returns to the non-locking position, and as shown in FIG. 6, the locking pin 26 comes off the locking recess 51 of the metal stopper plate 52, so that the door D Can be rotated in the closing direction. As described above, since a series of operations for fixing the door D to the floor F with the door D opened and releasing the fixing can be performed only by stepping on the pressing plate 22, the legs are forcibly bent and the waist is bent. Since it can be done while standing without doing it, it can be easily performed even by a person with a handicap.
