Description

  The present invention relates to a door stopper that regulates the degree of opening of a door and holds the door in an open state.

  In order to prevent the doors from colliding with a wall or the like when they are opened, the door stopper (or door stop device) as shown in FIG. 7 is conventionally provided. . The door stopper S is attached to the base material S1, a base material S1 made of metal or the like fixed to the floor, a cushioning member S2 such as rubber attached at an upper position where the door contacts the base material S1, and the base material S1. And a hook-shaped anti-slip tool S3 that is locked to the door.

  However, this kind of door stopper is usually provided on the wall so as to protrude from the floor, so that there are inconveniences such as obstructing the cleaning of the floor or catching a foot to get injured. Moreover, in order to hold the door in an open state, a person must perform an operation of locking the anti-staking tool S3 to the locking part of the door or removing the anti-locking tool S3. Since the anti-turning tool S3 and the locking portion of the door are in a low place, there is a problem that the waist must be bent or bent, which is very complicated and burdensome.

  The problem to be solved by the present invention is that the door can be kept open at the same time that the door is further opened, and the door can be closed by a simple operation even when a strong external force is applied in the door closing direction. The object is to provide a door stopper that can be blocked.

In order to solve the above-described problems, the present invention is a door stopper that regulates the degree of opening of the door and holds the door in an open state, and includes a locking portion and a movable portion, and the movable portion is placed on the floor. A base that is disposed and is substantially flush with the floor, and a rotating plate that is rotatably supported by the base so as to be substantially flush with the floor, and the locking portion is a case attached to the door; A magnet held in the case and a lock part provided in the case are provided. When the door is opened, the rotating plate of the movable part is sucked by the magnet and locked to the rotating plate, and the door is closed. The lock part has an operating body rotatably provided on the case, and an operating body for locking and unlocking the operating body . and, said operating body, the locking operation of the operating body Rotates in the direction, the is attracted by the magnet engages the rotating plate that is engaged with the engaging portion to lock the rotary plate, to prevent obstruction of the door in an open state, the working body, The rotating body is rotated in the other direction by the unlocking operation of the operating body, and the engagement of the rotating plate attracted by the magnet and locked to the locking portion is released to unlock the rotating plate, and is in an open state. The door is not blocked.

According to such a configuration, when the door is opened up to a certain point , the rotating plate of the movable part is attracted by the magnet of the locking part to lock the locking part, thereby restricting the opening of the door, The door can be kept open. In this state, when a force is applied to the door in the closing direction, the suction of the rotating plate of the movable part by the magnet is released, the locking of the rotating plate is released, and the door can be closed.

Therefore, the rotating plate of the movable part may be structured to be attracted by the magnet and locked to the locking part, and in normal times, when the movable part is provided on the floor side, the rotating plate of the movable part does not protrude from the floor. It is possible to prevent the floor surface from being obstructed or being caught by a foot with a very compact configuration.

On the other hand, if the lock part is locked when the door is held open, the lock part can prevent the door from being closed, so an external force such as strong wind acts in the door closing direction. However, it is possible to easily prevent the door from being closed arbitrarily.

Further, the present invention, the locking unit is actuated in order to prevent the operating body that is locking operation and unlocking operation, the closure of the door to lock the rotary plate by the locking operation of the operating body, the operating body And an actuating body that releases the lock of the rotating plate by the unlocking operation and does not prevent the door from being closed . In this case, the door is blocked or released by the operating body by locking or unlocking the operating body. At this time, even if the lock part is arranged in a low place, the operation part can be operated with a foot, so there is no need to bend or bend the waist, and the door can be blocked and released by simple operation. Can do.

Further, the present invention, the actuating member is rotatably provided in the case, when rotated in one direction, it is sucked by the magnet moves upward, engaging the rotary plate that is engaged with the engaging portion The rotary plate is locked to prevent the door from being closed in the open state. In this case, it is only necessary that the operating body be rotatably provided at the lower portion of the door, so that a compact configuration can be realized.

Further, the present invention is characterized in that the operating body can be rotated in one direction when the operating body is locked, and the operating body can be rotated in the other direction when the operating body is unlocked. In this way, if the operating body is locked only when necessary, the operating body can rotate in one direction to prevent the door from being closed, and otherwise it can be operated by unlocking the operating body. It is possible to prevent the body from rotating in the other direction and preventing the door from being blocked.

Further, the present invention, the movable portion, and the base substantially flush with each other and the disposed to the floor on the floor, a rotary plate which is rotatably supported on the base so as to form a substantially flush with the floor made, the locking portion includes a casing attached to the door, and a magnet held in the casing, a lock portion provided in the case, when the door is opened, the by the magnet The rotating plate of the movable portion is sucked, and the locking portion is locked to the rotating plate to restrict the opening of the door .

  By doing so, the base of the movable part and the rotating plate do not protrude from the floor surface, and it becomes a very compact configuration without obstructing the cleaning of the floor surface or catching the foot.

According to the present invention , the rotating plate of the movable part may be structured to be attracted to the engaging part by being attracted by the magnet, and in normal times, when the movable part is provided on the floor side, the rotating plate of the movable part is separated from the floor. it can der because possible not to protrude, very not to snag a foot or to obstruct the cleaning of the floor surface can provide a door stop for a compact construction.

  Furthermore, if the lock part is locked when the door is held in the open state, the door can be blocked by the lock part, so that an external force acts in the door closing direction by a simple operation. However, if it is applied to the entrance door, etc., it can be prevented from closing the door due to strong wind, and it is possible to easily take in and out the luggage. It is very convenient.

In addition, according to the present invention , the operating body can be locked or unlocked to prevent or release the door from being closed by the operating body. There is no need to bend or bend, and the door can be blocked and released by simple operations.

Further, according to the present invention , since the operating body only needs to be provided on the case so as to move up and down, a compact configuration can be realized.

Further, according to the present invention , by locking the operating body only when necessary, the operating body can be moved down by the holding means to prevent the door from being closed. If the operation is unlocked, the operating body can be held in the upward movement state.

In addition, according to the present invention , the base of the movable part does not protrude from the floor surface, and does not obstruct the cleaning of the floor surface or get caught by a foot, so that the configuration is very compact.

  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.

  In addition, a rectangular through hole 17 into which the operation body 41 constituting the lock unit 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 accommodated 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 in FIG. 1, the right end of the operating body 41 is engaged with a leaf spring 49 as a holding means in the cover 13, and the 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 in which the tip of the hook-like operating body engages with an engaging portion provided on the floor side is conceivable.

  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.
