  An embodiment of the present invention will be described with reference to FIGS. 1 is a front view, FIG. 2 is a left side view, FIG. 3 is a right side view, FIG. 4 is a plan view, FIG. 5 is a partial plan view, and FIG. 6 is a perspective view for explaining operations in a separated state. is there.

  As shown in these drawings, a door stopper engaging portion 10 is attached to the lower corner of the other end of the door 1 that is rotatably supported by a hinge on one end, and the degree of opening of the door 1 is almost fully open ( For example, the movable portion 30 of the door stopper is embedded in the floor surface below the locking portion 10 when it is about 90 ° or about 180 °.

  The locking portion 10 includes a case 11 attached to the door 1 and a magnet 25 held in the case 11. The case 11 is a cover having a substantially rectangular plate-shaped main portion 12 that is screwed directly to the door 1 and a lower surface side that covers the portion excluding the left end portion of the main portion 12 and is attached to the main portion 12. 13. Reference numeral 14 denotes a plurality of screw insertion holes formed in the main portion 12.

  A magnet space 15 that accommodates the magnet 25 is formed in the lower right portion of the cover 13, and a boss 16 that is inserted through the central through hole 26 of the magnet 25 and supports the magnet 25 is integrated inside the cover 13. It is planted in. By the way, this magnet 25 is constituted by a rectangular parallelepiped magnet main body 27 and two rectangular yoke plates 28 disposed so as to sandwich the magnet main body 27, as shown in FIGS. ing.

  Further, a rectangular through hole 17 into which the operation body 41 constituting the lock portion 40 is inserted is formed on the left end surface of the cover 13. Further, an operating body space 18 in which the operating body 45 constituting the lock portion 40 is housed so as to be movable up and down is formed at a position in front of the left end portion in the cover 13. Further, at the lower end of the main portion 12, a long locking body 19 is integrally formed on the left and right sides having an L-shaped cross section with the upper end protruding forward. The rotating plate comes into contact.

  Next, as shown in FIGS. 1, 2, and 5, the movable portion 30 is formed on the base 31 and a rectangular thin base 31 that is disposed at a predetermined position on the floor and screwed. Since the rectangular recess 32 and the rotating plate 34 that is disposed in the recess 32 and processed into a roll shape are rotatably supported via the support shaft 33, the base 31 is thin. The base body 31 hardly protrudes from the floor surface and is substantially flush with the floor face, and the rotating plate 34 forms the same face as the top face of the base body 31 when not attracted to the magnet 25 and is almost flush with the floor face. Is made.

  Here, an elliptical through-hole 35 is formed at the left end of the rotating plate 34 so that the lower end of the operating body 45 can be freely inserted and removed. The lock part 40 is comprised with the body 45 and the spring mentioned later. Reference numeral 37 denotes a plurality of screw insertion holes for fixing the base 31 to the floor.

Therefore, when the door 1 is opened to a substantially fully opened state, the rotating plate 34 is attracted by the magnet 25 of the locking portion 10 on the door 1 side, and the rear end portion of the rotating plate 34 moves upward, and the locking body 19. The door 1 is held in an open state since the door 1 is prevented from being further opened and the rotating state of the rotating plate 34 by the magnet 25 is maintained. On the other hand, in order to close the door 1 from this state, by applying a little force to the door 1 in the closing direction (see FIG. 6), the suction of the rotating plate 34 by the magnet 25 is released, and the door 1 is easily closed. Rotate in the direction.

  Subsequently, as shown in FIGS. 1, 4, and 6, the operation body 41 of the lock unit 40 has an L shape in plan view, and the wide left end portion is exposed to the outside from the through hole 17 of the cover 13. The right end is pivotally supported by a convex boss 22 (see FIG. 3) integrally formed on the inner surface of the cover 13 at a position above the magnet space 15 in the cover 13.

  Further, as shown in FIG. 1 in particular, the operating body 45 of the lock portion 40 is a rectangular parallelepiped shape located between the upper end portion 45a and the lower half portion 45b, and the upper end portion 45a and the lower half portion 45b. The spiral spring 46 is wound around the upper end 45a of the operating body 45, and both ends of the spring 46 are connected to the upper and inner surfaces of the cover 13 and the operating body 45 in the operating body space 18. The operating body 45 is urged downward through the engaging portion 45c. At this time, the actuating body 45 is arranged so that the lower end surface of the actuating body 45 in the downward movement state is positioned slightly above the upper surfaces of the rotating plate 34 and the base body 31 before being attracted by the magnet 25. It is desirable to do.

  By the way, a boss 42 (see FIG. 1) is integrally formed at a substantially central portion of the operation body 41, and an operation body is formed in an elongated hole 47 formed vertically at the center portion of the engaging portion 45c of the operating body 45. The boss 42 of 41 is loosely inserted and engaged, and the operating body 41 rotates around the boss 22. When the left end portion of the operating body 41 is pushed up, the boss 42 of the operating body 41 comes into contact with the upper surface of the long hole 47, and the operating body 45 moves up against the spring 46 as will be described in detail later. Kept in a state. On the other hand, when the left end portion of the operating body 41 is pushed down, the operating body 45 is moved downward by the bias of the spring 46.

  At this time, as shown particularly in FIG. 1, the right end of the operating body 41 engages with a leaf spring 49 as a holding means in the cover 13, and this leaf spring 49 has a substantially concave shape. Is latched by the latching portion on the right inner surface of the cover 13 and the central portion protrudes to the left and is curved, and the right end of the operating body 41 is in sliding contact with the curved central portion.

  When the door 1 is held in the open state by the suction of the rotating plate 34 by the magnet 25, when the lock operation of the operating body 41, that is, when the left end portion of the operating body 41 is pushed downward, the right end of the operating body 41 is Slidably contact the curved portion of the leaf spring 49 from below to above, and the operating body 45 is moved downward by the bias of the spring 46 and the lower end of the operating body 45 is inserted into the through hole 35 of the rotating plate 34. At this time, when the right end of the operating body 41 gets over the curved portion of the leaf spring 49, a so-called click feeling is generated, so that the operator can feel that the locking operation has been performed.

  Furthermore, since the left end portion of the operation body 41 abuts the lower surface of the through-hole 17, the lowering of the left end portion of the operation body 41 is restricted, so that the right end of the operation body 41 stops at a position where it has crossed the curved portion. Since the lower end of the operating body 45 is held in a state where the lower end of the operating body 45 is fitted in the through hole 35 of the rotating plate 34, the door 1 is blocked even if an external force such as strong wind acts on the door 1 in the closing direction. is there.

  When the operating body 41 is unlocked, that is, when the left end of the operating body 41 is pushed upward, the operating body 45 resists the spring 46 while the boss 42 of the operating body 41 abuts the upper surface of the long hole 47. The lower end of the operating body 45 is pushed out from the through hole 35 of the rotating plate 34 to release the locked state (unlocked state), and the operating body 45 is held in the upward movement state.

At this time, the right end of the operating body 41 is in sliding contact with the curved portion of the leaf spring 49 from the top to the bottom. However, when the right end of the operating body 41 gets over the curved portion, the operating body 41 is moved by the spring force of the leaf spring 49.
It is desirable to set the spring forces of the leaf spring 49 and the spring 46 so that the clockwise moment applied to the spring exceeds the counterclockwise moment applied to the operating body 41 by the spring force of the spring 46.

  Therefore, for example, when applied to a front door, when the door 1 is opened to a substantially fully open position, the rotating plate 34 of the movable part 30 on the floor side is attracted and rotated by the magnet 25 of the locking part 10 on the door 1 side. The upper end of the plate 34 is moved upward and locked to the stepped portion 20 of the locking body 19, thereby opening the door 1 only by restricting further opening of the door 1 and opening the door 1. It is possible to hold and remove the luggage from the entrance very easily.

  On the other hand, the holding force of the door 1 due to the magnet 25 being attracted to the door 1 such as a strong wind blows when the door 1 is held in the open state by attracting the rotating plate 34 by the magnet 25 in this way. When some external force exceeding 1 is applied in the closing direction of the door 1, the suction of the rotating plate 34 by the magnet 25 of the door 1 is released and the door may be closed arbitrarily. In such a case, by pushing down the operating body 41, the operating body 45 moves downward against the spring 46 and the lower end thereof is inserted into the through hole 35 of the rotating plate 34. It is possible to prevent the door 1 from being obstructed by a strong wind or the like by a simple operation without performing a special operation such as bending and hooking.

  Further, even if the operating body 41 is pushed down and the operating body 45 is moved downward when the door 1 is closed, and the door 1 is opened in that state, as described above, Since the end surface is positioned slightly above the upper surface of the rotating plate 34 and the base 31, the rotating plate 34 is attracted by the magnet 25 and the rear end portion of the rotating plate 34 tends to move upward. The lower end of the operating body 45 slides on the upper surface of the rotating plate 34 until the lower end of 45 is fitted into the through hole 35 of the rotating plate 34. Therefore, the opening of the door 1 can be continued without damaging any member until the lower end of the operating body 45 is fitted into the through hole 35, and the lower end of the operating body 45 is fitted into the through hole 35. At the same time, the rear end of the rotating plate 34 moves upward and engages with the stepped portion 20 of the engagement body 19, thereby restricting the opening of the door 1 and simultaneously locking the door 1 to the opened state.

  Therefore, according to the above-described embodiment, the movable portion 30 does not protrude greatly from the floor as in the prior art, and the rotating plate 34 is substantially flush with the floor surface in a normal state, which obstructs the cleaning of the floor. The door 1 can be controlled to open very easily and the door 1 can be held in an open state simply by opening the door 1 to a fully open state. It is possible to provide a door stopper having a configuration that is very compact and easy to handle.

  Further, since the operation body 41 is locked, that is, by simply depressing the operation body 41, the door 1 in the open state can be blocked and held in the locked state, so that a strong wind or other external force is applied to the door 1 in the closing direction. Even if it acts, the door 1 can be reliably held in an open state, which is very convenient. At this time, since the left end portion of the operation body 41 is led out of the cover 13, the operation body 41 can be easily pushed down or pushed up with a foot.

  Further, the leaf spring 49 allows the operating body 45 to move downward when the operating body 41 is locked, and keeps the operating body 45 in the upwardly moving state when the operating body 41 is unlocked. Therefore, it is possible to operate the operating body 41 only when it is necessary to lock it.

In the above-described embodiment, the case has been described in which the actuating body 45 moves up and down in conjunction with the rotation of the operating body 41, thereby locking or unlocking the door 1 in the open state. The lower part engages with the floor when rotating the working body in one direction to prevent the door 1 from being blocked, and the engagement is released when the working body rotates in the other direction. May be. As an engagement in this case, a mode is conceivable in which the tip of the hook-shaped actuator is engaged with an engaging portion provided on the floor side.

  Moreover, you may comprise so that operation body itself may engage with a floor side by the lock operation and unlocking operation of the operation body provided in the door side.

  Further, in the above-described embodiment, the case where the locking portion made of a magnet is provided on the door side and the movable portion is provided on the floor side is opposite. However, the locking portion made of a magnet is movable on the floor side. It goes without saying that the portion may be provided on the door side.

  In addition, a push button and an engaging member that protrudes from the floor surface toward the door by pressing the push button are provided on the floor so that the door can be freely opened and closed, and the door is opened by engaging the engaging member with the door. Of course, it may be locked or unlocked.

  Furthermore, in the embodiment described above, the leaf spring 49 is used as the holding means, but the holding means is not limited to this, and in short, the operating body can be rotated in one direction when the operating body is locked, and the operating body What is necessary is just to be able to hold | maintain the state rotated to the other direction at the time of unlocking operation.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

As described above, the door stopper that restricts the degree of opening of the door 1 and holds the door 1 in the open state includes the locking portion 10 and the movable portion 30. The movable unit 30 includes a base 31 disposed on the floor and a rotating plate 34 that is rotatably supported by the base 31. The locking part 10 includes a case 11 attached to the door 1 and a magnet 25 held in the case 11.
