  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described with reference to the drawings.

  FIG. 1 shows a door 10 having a door stop according to the present invention. The door 10 is attached to a door frame 12 provided on a wall 11 by hinges 13, 13 and the like. A door-side member 30 per door is housed and attached to the lower end of the door 10 so as to be partially broken and show the inside. 20 is a floor and 21 is a pedestal for a door. The pedestal 21 slightly protrudes from the floor surface 20, but the upper surface is flat and is made of a magnetic material so that the magnet attracts it.

  2 is a view taken in the direction of the arrow Y in FIG. 1, and the pedestal 21 is fixed to the floor 20 at a position where the door 10 is almost fully opened. Arrow X represents the door opening direction.

  FIG. 3 is a cross-sectional view of the side surface of the lower end portion of the door 10, in which the door-side member 30 per door according to the present invention is housed. The door-side member 30 is mainly composed of a stopper 31 housed in the case 36 and is built in and fixed to the lower end of the door 10. The stopper 31 is rotatably attached to a rotary shaft 32 projecting from the case 36, is configured of an elastic body, and has a magnet 35 built therein. The magnet 35 is embedded in a portion closest to the floor surface 20 in a state where the stopper 31 is incorporated in the door side member 30. Reference numeral 33 denotes a spring member such as a torsion coil spring, which urges the stopper 31 in the direction of the arrow P and normally holds the stopper 31 so as not to contact the floor surface 20. Reference numeral 34 denotes a protrusion that restricts the stopper 31 from rotating further in the arrow P direction. The protrusion 34 is formed of a screw or the like, and the distance between the stopper 31 and the floor surface 20 can be adjusted so that the length of the protrusion 34 can be changed. Reference numeral 37 denotes a spring which urges the stopper 31 in the direction of arrow P. The shape of the stopper 31 is substantially triangular, and the hole through which the rotation shaft 32 passes is provided near one vertex of the triangle, and the length of the two sides other than the lower side surface S corresponding to one side of the triangle facing the vertex is long. Unlikely, the length of the side surface contacting the protrusion 34 is configured to be longer than the length of the other side surface.

  As shown in FIG. 5A, the pedestal 21 is a plate made of a magnetic material having a flat upper surface, and is fixed to the floor with bolts 22 and 22. FIG. 5B shows another embodiment of the pedestal 21 with a groove 23 on the upper surface. 5 (c) and 5 (d) show still another embodiment of the pedestal 21, FIG. 5 (c) is a plan view, and FIG. 5 (d) is a side view. Yamagata 24 is applied. Both the groove 23 and the chevron 24 are effective in increasing the frictional force between the stopper 31 and the pedestal 21.

  The door-to-door operation configured as described above will be described below mainly with reference to FIGS. As shown in FIG. 3, the door side member 30 and the floor surface 20 in the closed door 10 as shown in FIGS. 1 and 2 are in contact with the protrusion 34 by the urging force of the spring member 33 as shown in FIG. The floor surface 20 is not in contact. When the door 10 is opened in the door opening direction indicated by the arrow X, the door-side member 30 reaches above the pedestal 21. FIG. 4A shows the state at this time. Since the pedestal 21 is made of a magnetic material, the magnet 35 is attracted by a magnetic force, and the stopper 31 resists the spring force of the spring member 33 around the rotation shaft 32. Then, it rotates in the direction of arrow Q, and the lower side surface S of the stopper 31 slightly contacts the upper surface of the base 21. When the door 10 further moves in the opening direction, the stopper 31 is further rotated by friction on the upper surface of the base 21, and the stopper 31 wedges between the lower end of the door 10 and the base 21 while resisting the spring force of the spring 37. It stops in the state shown in FIG. 4 (b). That is, movement in the door opening direction is restricted. This is because the length of the lower side surface S from the rotation shaft 32 on the lower side surface S that contacts the upper surface of the base 21 is increased with the rotation of the stopper 31, so that the distance between the lower end of the door 10 and the base 21 is increased. This is because a wedge-like effect is exhibited between the lower end of the door 10 and the pedestal 21 when it becomes longer than the length. When closing the door 10, it is sufficient to release the hand from the door 10, and since a door closer (not shown) is normally installed on the door 10, the state of the door side member 30 and the base 21 is shown in FIG. Moving to 4 (a), the door 10 is closed. The spring 37 is for assisting the function of the door closer at this time.

  Next, another embodiment of the present invention will be described. In FIG. 6, the same components as those in FIG. 3 are given the same numbers, but the door-side member 50 per door has a stopper 51. The stopper 51 is rotatably attached to a rotating shaft 32 projecting from the case 36 and incorporates a magnet 35, but the material is not limited to an elastic body but may be a rigid body. The magnet 35 is embedded in a portion closest to the floor surface 20 in a state where the stopper 51 is incorporated in the door side member 50. The shape of the stopper 51 is a substantially isosceles triangle, and a long hole 52 is provided in a portion near the apex of the isosceles triangle in a direction perpendicular to the lower side surface T corresponding to the base of the isosceles triangle. The rotary shaft 32 and the lower side surface T side of the stopper 51 are urged in a repulsive direction by a spring 53 that is passed through the hole 52 and attached to the long hole 52. With this configuration, even if the stopper 51 is a rigid body, it has elasticity in a direction perpendicular to the lower side surface T. The distance from the rotating shaft 32 to the lower side surface T is not the same, and the distance on the line passing through the rotating shaft 32 and perpendicular to the substantially central plane of the lower side surface T is the longest (strictly speaking, both end portions of the plane) The both ends of the lower side surface T are formed as rounded curved surfaces R. Reference numeral 54 denotes a spring member such as a spring which urges the stopper 51 in the direction of arrow P and normally holds the stopper 51 so as not to contact the floor surface 20.

  The door-to-door operation configured as described above will be described below mainly with reference to FIGS. The state of the door side member 50 and the floor surface 20 in the door 10 in the closed state as shown in FIGS. 1 and 2 is such that the stopper 51 abuts against the protrusion 34 by the biasing force of the spring member 54 as shown in FIG. The floor surface 20 is not in contact. When the door 10 is opened in the door opening direction indicated by the arrow X, the door-side member 50 reaches above the pedestal 21. The state at this time is shown in FIG. 7A. Since the pedestal 21 is made of a magnetic material, the magnet 35 is attracted by the magnetic force, and the stopper 51 is moved to the spring force of the spring member 54 around the rotation shaft 32. Against the rotation in the direction of arrow Q, the lower side surface T (curved surface R) of the stopper 51 slightly contacts the upper surface of the base 21. When the door 10 further moves in the opening direction, the stopper 51 is further rotated by friction on the upper surface of the base 21, and the stopper 51 wedges between the lower end of the door 10 and the base 21 while resisting the spring force of the spring member 54. It stops in the state shown in FIG. 7 (b). That is, movement in the door opening direction is restricted. This is because the length of the lower side surface T from the rotating shaft 32 on the lower side surface T contacting the upper surface of the base 21 is increased with the rotation of the stopper 51, so that the distance between the lower end of the door 10 and the base 21 is increased. This is because a wedge-like effect is exhibited between the lower end of the door 10 and the pedestal 21 when it becomes longer than the length. Since the stopper 51 is given an elastic force by a spring 53 and the central portion of the lower side surface T is a flat surface, the force balance between the closing force of a normally installed door closer not shown and the spring force of the spring member 54 is not shown. The door 10 can be stably stopped and held in the opened state in the state of FIG. When the door 10 is closed, if the door 10 is lightly pushed in the closing direction by hand, the balance is lost, and the state of the door side member 50 and the pedestal 21 moves from FIG. 7B to FIG. Moves in the closing direction and closes.

  The door stop according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims. For example, in the above description, the stopper 51 is formed such that both ends of the lower side surface T are curved surfaces R. However, the curved surface R close to the magnet 35 is effective in the present invention, and both ends of the lower side surface T are effective. The curved surface R should just be formed in at least one of these.
