When the release member 32 is connected to the main body member 14 as described above in this state, the ball 41 is urged toward the release member 32 while being in contact with the release member 32.
Then, the biased ball 41 enters the positioning recess 32c, and the position of the release member 32 is determined. The position of the release member 32 is the protruding position and the retracted position of the release member 32.
The release member 32, the positioning means 40, and the release member storage portion 13b are the release mechanism portion.

Next, the stopper member 11 will be described. As shown in FIGS. 9 and 10, the stopper member 11 is provided with a pedestal 22, and a protruding portion 24 including a swing plate 23 and a moving plate 25. Further, the swing plate 23 is swingably connected by a base 22 and a fixed shaft 26, and the moving plate 25 is swingably connected to the swing plate 23 by a moving shaft 27.
And the protrusion part 24 engages with the recessed part 13 of the said member 10 for doors, and prevents the movement of a door. At this time, the protrusion 24 is protruded by the magnetic force of the magnet 20a, and the protrusion 24 is retracted by gravity.

The pedestal 22 can be fixed, and the stopper member 11 can be fixed by fixing the pedestal 22 to the floor 91. More specifically, the fixing hole 30 is provided in the pedestal 22, and the pedestal 22 is fixed to the floor 91 by inserting the screw 36 into the fixing hole 30 and fixing it to the floor 91.
The pedestal 22 is provided with a storage recess 28 in which the protrusion 24 can be stored. The storage recess 28 is located on the side opposite to the side fixed to the floor 91, and is positioned on the upper side when the pedestal 22 is fixed to the floor 91. Then, as shown in FIG. 9, when the protrusion 24 is stored in the storage recess 28, the upper side of the stopper member 11 becomes substantially planar.
The pedestal 22 is provided with a fixed shaft through hole 48 into which the fixed shaft 26 can be inserted.

The moving plate 25 is a rectangular plate-shaped member. The moving plate 25 is a magnetic material. The size of the moving plate 25 is smaller than the size of the concave portion 13 of the door member 10 and can be stored in the concave portion 13.
The moving plate 25 is provided with a moving shaft insertion hole 52, and the moving shaft 27 can be inserted into the moving shaft insertion hole 52.

The swing plate 23 is a substantially “U” -shaped plate-like member, and a notch portion 23 a inside the swing plate 23 “U” is substantially the same as the outer shape of the moving plate.
Further, the swing plate 23 is provided with a fixed shaft insertion hole 50 and two moving shaft insertion holes 51. The fixed shaft 26 can be inserted into the fixed shaft insertion hole 50, and the movable shaft 27 can be inserted into the movable shaft insertion hole 51. When the rocking plate 23 and the moving plate 25 are matched with the same plate surface, the overall shape is a rectangular shape, which is almost the same shape as the housing recess 28, and the two moving shaft insertion holes 51 are formed. The moving shaft insertion hole 52 is positioned in a straight line and is substantially parallel to the fixed shaft insertion hole 50.

Then, the fixed shaft 26 is inserted by aligning the positions of the fixed shaft through hole 48 of the base 22 and the fixed shaft insertion hole 50 of the swing plate 23. Then, the pedestal 22 and the swing plate 23 are connected and can be swung around the fixed shaft 26.
Further, the moving shaft 27 is inserted by aligning the positions of the moving shaft insertion hole 51 of the swing plate 23 and the moving shaft insertion hole 52 of the moving plate 25. Then, the rocking plate 23 and the moving plate 25 are connected and can be swung around the moving shaft 27. Further, the fixed shaft 26 and the moving shaft 27 are located substantially in parallel.

That is, the moving plate 25 and the base 22 are connected via the swing plate 23 and can be swung at two places, the fixed shaft 26 and the moving shaft 27. Therefore, the distance between the movable plate 25 and the pedestal 22 can be changed by increasing the relative angle between the swing plate 23 and the pedestal 22. Further, the fixed shaft 26 and the moving shaft 27 are substantially parallel, and the relative angle between the moving plate 25 and the swing plate 23 is set to be approximately the same as the relative angle between the swing plate 23 and the base 22. The distance between the moving plate 25 and the pedestal 22 can be changed while the surface of the plate 25 and the surface of the pedestal 22 are parallel.
Further, the moving plate 25 can protrude and retract regardless of the position of the swing plate 23.

  Further, when the pedestal 22, the swing plate 23, and the moving plate 25 are connected as described above and the storage recess 28 of the pedestal 22 is moved upward, the swing plate 23 and the transfer plate 25 are stored in the storage recess 28.

The usage method of the door stopper 1 is demonstrated.
First, the door stopper 1 is attached to the door 90. Specifically, the screw hole 37 is screwed in the state in which the concave portion 13 of the door member 10 faces the floor 91 and the through-hole direction of the shaft hole 38 is parallel to the door 90 and the floor 91. The door member 10 is attached by inserting the screw 36 and fixing the screw 36 and the door 90 together.
Next, the stopper member 11 is arranged on the movement track of the door member 10 when the door 90 rotates, and the penetration direction of the fixed shaft through hole 48 is perpendicular to the movement direction of the door member 10. In a state in which the fixed shaft 26 is in front of the moving shaft 27 in the moving direction of the door member 10, the screw 36 is inserted into the fixing hole 30 to fix the screw 36 and the floor 91 to the stopper. The member 11 is attached.
At this time, the vertical distance between the door member 10 and the stopper member 11 is set within a range in which the protrusion 24 can engage with the recess 13.

And the movement of the door stopper 1 at the time of fixing the position of a door is demonstrated using FIGS. 11 to 14, the left side is the door 90 side, and when the door 90 is opened, the door member 10 moves to the right.
When the door member 10 and the stopper member 11 are separated from each other, as shown in FIG. 11, the protrusion 24 (the swing plate 23 and the moving plate 25) of the stopper member 11 is received in the storage recess 28 of the base 22. Yes. In the state shown in FIG. 11, the release member 32 of the door member 10 is in a retracted state and is positioned by the positioning means 40.

  When the door 90 is opened from the state shown in FIG. 11, the protrusion 24 (the swing plate 23 and the moving plate 25) is attracted to the magnet 20a provided in the inclined portion 15 as shown in FIG. Engage with part 15.

When the door 90 is further opened from the state shown in FIG. 12, the protruding portion 24 slides with the inclined portion 15, and the protruding portion 24 advances in the upper left direction relative to the door member 10. The magnet is attracted to the magnet 20b disposed in the vicinity of the one side surface portion 18. If the door 90 is kept open as it is, the door member 10 moves to the right, and the protrusion 24 is attracted by the magnet 20b disposed in the vicinity of the first side face portion 18, so that the protrusion 24 is recessed 13. the top surface portion and 17 and the sliding proceeds relatively leftward against the door member 10, the rotation of the door 90 is stopped by abutting the first side surface portion 18 or the receiving member 9. The protrusion 24 engages with an engagement space 21 formed by the top surface portion 17 and the receiving member 9. FIG. 13 shows this state.

  In the state shown in FIG. 13, the moving plate 25 is magnetized by the magnet 20b disposed in the vicinity of the first side surface portion 18, and the end on the moving shaft 27 side has a different polarity from the exposed surface of the magnet 20b. The end 25a has the same polarity as the exposed surface of the magnet 20b. Therefore, the end 25a of the moving plate 25 is attracted to a surface at a position facing the exposed surface of the magnet 20a provided on the inclined portion 15. As a result, the movable plate 25 reliably and firmly holds a posture parallel to the floor 91.

  As described above, when the moving plate 25 is engaged with the recess 13 and is parallel to the floor 91, when the door 90 tries to rotate in the opening direction, the moving shaft 27 of the moving plate 25. Since the end portion on the side abuts against the receiving member 9 or the first side surface portion 18, the door 90 cannot rotate. Further, when the door 90 is about to rotate in the closing direction, the end portion 25a of the moving plate 25 abuts against the second side surface portion 19, and thus the door 90 cannot similarly rotate. Therefore, in this state, the position of the door 90 is firmly locked.

Here, since the receiving member 9 is provided in the recess 13, when the door 90 is opened from the state shown in FIG. 12, for example, the door 90 rotates at an unexpectedly high speed. The protrusion 24 is located above the bent portion of the receiving member 9 even when it does not slide with the top surface portion 17 or when it is not attracted to the magnet 20b disposed near the first side surface portion 18. If it contacts the first side surface portion 18 or the receiving member 9 at the position, a part of the protruding portion 24 is disposed in the engaging space 21 constituted by the top surface portion 17 and the receiving member 9. Therefore, it is possible to more reliably prevent the door 90 from rotating in the opening direction.
Further, even when the protruding portion 24 and the moving plate 25 are separated from the magnet 20b from the state shown in FIG. 13 because the magnetic force of the magnet 20b is weakened, the receiving member 9 moves downward of the protruding portion 24. Therefore, it is possible to more reliably maintain the state in which the door 90 is prevented from rotating in the opening direction.

  To release the locked state and close the door 90, first, the release member 32 is operated from the state shown in FIG. Then, when the moving plate 25 is pressed by the release member 32, the end portion 25a of the moving plate 25 is lowered downward. Therefore, the movable plate 25 is not in a posture parallel to the floor 91, and the end portion 25a is in contact with the release member 32. Further, in this state, the contact of the end portion 25a with the second side surface portion 19 is prevented. FIG. 14 shows this state.

In the state shown in FIG. 14, the door 90 can be closed by applying a force in the closing direction with respect to the door 90.
More specifically, when a force is applied in the closing direction to the door 90 in the state shown in FIG. 14, the door member 10 moves to the left, so that the end 25a of the moving plate 25 slides with the release member 32, and then tilts. Slide with part 15. This is because the inclination of the part of the release member 32 and the inclined portion 15 with respect to the floor 91 is substantially the same. Further, when a force is applied to the door 90 in the closing direction, the door stopper 1 including the projecting portion 24 does not hinder the movement of the door 90, so that the door 90 can be closed.
That is, the protruding release member 32 has an effect of preventing the end portion 25a of the moving plate 25 from coming into contact with the second side surface portion 19, and the protruding portion 24 does not prevent the movement when the door 90 moves in the closing direction. Has an effect to induce.

Here, the case where the release member 32 is in the protruding state in the state shown in FIG. 11 will be described. When the release member 32 is rotated in the direction in which the door is opened while being in the protruding state, the protruding portion 24 is attracted to the magnet 20 a provided in the inclined portion 15 and is engaged with the inclined portion 15.
Next, the projecting portion 24 slides with the release member 32 after sliding with the inclined portion 15. Further, the protruding portion 24 advances in the upper left direction relative to the door member 10 and is attracted to the magnet 20 b disposed in the vicinity of the first side surface portion 18. If the door 90 is kept open as it is, the door member 10 moves to the right, and the protrusion 24 is attracted by the magnet 20b disposed in the vicinity of the first side face portion 18, so that the protrusion 24 is recessed 13. The top surface portion 17 of the door 90 slides to the left relative to the door member 10 and comes into contact with the first side surface portion 18 or the receiving member 9 to stop the rotation of the door 90. The protrusion 24 engages with an engagement space 21 formed by the top surface portion 17 and the receiving member 9.
That is, even if the release member 32 is in the projecting state, it does not affect the action and effect of preventing the door 90 from rotating in the opening direction. Therefore, regardless of the state of the release member 32, the door 90 does not rotate in the opening direction from the position where the stopper member 11 is disposed.

Since the door stopper 1 is configured in this way, it can be used as follows.
By using the release member 32 in the retracted state, the door 90 can be fixed in an unrotatable state at an arbitrary position on the rotation track. In addition, this state is firmly maintained while the release member 32 is in the retracted state, but can be easily released by setting the release member 32 to a protruding state.
By using the release member 32 in the protruding state, the rotation of the door 90 can be restricted so as not to open from the designated position.

  Moreover, since the magnet 20a is provided in the inclined part 15, when the door member 10 approaches the stopper member 11, compared with the structure in which only the magnet 20b is provided, the door member 10 and the stopper are provided. Since the protrusion 24 starts to protrude from a state where the distance between the members 11 is further away, it is possible to more reliably prevent problems such as the protrusion not being in time when the door 90 rotates at a faster speed than expected. it can.

In the above description, the receiving member 9 has a shape in which a part of a plate-like member having a substantially “L” side surface is bent by about 90 degrees, but this angle is not limited to 90 degrees. For example, you may incline toward the direction facing the top surface part 17 or the top surface part 17. FIG.
Further, the shape of the receiving member 9 is not limited to the above-described shape. For example, a member whose side surface of the receiving member 9 has a substantially “U” shape may be used. Accordingly, the shape of the receiving member storage portion 13 c may be changed to a shape corresponding to the shape of the receiving member 9.
That is, it is only necessary to assist the determination of the position where the protrusion 24 is engaged when engaging the protrusion 24 of the stopper member 11 and to maintain the posture of the protrusion 24 after the engagement.

  The door member 10 described above is attached to the surface of the door 90, but a space may be provided inside the door 90 and attached thereto.

  In the above description, the release member 32 is integrally formed with the operation portion 32a, but the operation portion 32a may be a separate member. That is, it is only necessary that the release member can be switched between the entry state and the withdrawal state by operating the operation unit 32a.

In the above description, two magnet storage units are provided, but the number of magnet storage units is not necessarily two. The number, position, and shape of the magnets to be arranged are arbitrary, and as many magnet storage units as the number of magnets to be arranged may be provided. That is, when the door 90 rotates in the opening direction and the door member 10 approaches the stopper member 11, the protrusion 24 can be reliably protruded, and when the protrusion 24 and the recess 13 are engaged, the movable plate 25. It is sufficient to function so as to hold the posture change and the posture after the posture change.
In the above description, the protrusion 24 of the stopper member 11 is constituted by the swing plate 23 and the moving plate 25, and the swing plate 23 is connected to the base 22 so as to be swingable by the swing shaft 26. The moving plate 25 is swingably connected to the swing plate 23 by the moving shaft 27 and can be stored in the storage recess 28 so that the upper side of the stopper member 11 is substantially flat. Is not limited to this. That is, it is only necessary that the protruding portion 24 protrudes and can be engaged with the concave portion 13 of the door member 10. Therefore, the positions of the rocking shaft 26 and the moving shaft 27 to be connected and the shapes of the rocking plate 23 and the moving plate 25 may be changed. For example, the moving plate 25 may be provided with a bowl-shaped portion that engages with the opening of the release member storage portion 13b.
