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.

  Conventionally, a door stopper (or door stop device) as shown in FIG. 7 is provided to prevent the doors from colliding with a wall or the like and being damaged when the door of the entrance or room is opened. . The door stopper S is provided with a base material S1 made of metal or the like fixed to the floor, a buffer member S2 such as rubber mounted at an upper position where the door comes into contact with the base material S1, and a door base S1. And a hook-shaped lifting stopper S3 locked to the door.

  However, since this kind of door stopper is usually provided so as to protrude from the floor near a wall, there are inconveniences such as obstructing floor cleaning and catching an injured foot. Moreover, in order to hold the door in the open state, a person must perform the operation of locking the lifting stopper S3 to the locking portion of the door or removing the locked lifting stopper S3. Since the lifting stopper S3 and the locking portion of the door are located at a low place, the waist must be bent or bent, resulting in a problem that the load is extremely complicated and burdensome.

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

  In order to solve the above-mentioned problem, the present invention provides a door stopper which regulates the degree of opening of a door and holds the door in an open state, wherein a locking portion comprising a magnet provided on one of a door and a floor, A movable portion provided on the other side of the door or the floor, which is attracted by the magnet and is locked by the locking portion, and is detached from the locking portion by applying a force to the door in a closing direction; And a lock unit for preventing the door from being closed and unlocking the door by an unlocking operation.

  According to such a configuration, when the door is opened to a certain position, the movable portion is attracted by the magnet of the locking portion and locked to the locking portion, thereby restricting the opening of the door and opening the door. Can be kept in a state. In this state, if a force is applied to the door in the closing direction, the suction of the movable portion by the magnet is released, the movable portion is unlocked, and the door can be closed.

  Therefore, the movable part may be structured to be attracted by the magnet and locked to the locking part. In normal times, when the movable part is provided on the floor side, it is possible to prevent the movable part from projecting from the floor. Conversely, when the magnet of the locking part is buried in the floor surface and the movable part is provided on the door side so that it can move only when the magnet is attracted and lock to the locking part, it locks from the floor surface It is possible to prevent the magnet of the section from projecting, and it is possible to prevent the magnet from getting in the way of cleaning the floor surface or being caught by the foot with a very compact configuration.

On the other hand, if the lock portion is operated while the door is held in the open state, the door can be blocked by the lock portion, so that an external force such as a strong wind acts in the direction of closing the door. In addition, it is possible to easily prevent the door from being closed without permission.

  In addition, the present invention provides an operation body in which the lock portion is provided on the door and is operated to perform a lock operation and an unlock operation, and an operation body that operates to prevent the door from being closed by a lock operation of the operation body. It is characterized by becoming. Then, by closing or unlocking the operating body, the closing of the door is prevented or released by the operating body. At this time, even if the lock portion is disposed in a low place, the operation portion can be operated with the foot, so that the waist does not need to be bent or bent, and the blockage of the door can be blocked and released by a simple operation. Can be.

  Further, the present invention is characterized in that the operating body is provided on the door side so as to be vertically movable, and a lower end thereof engages with the floor side when moving down to prevent the door from being closed. In this case, since the operating body may be provided at the lower part of the door so as to be vertically movable, a compact configuration can be realized.

  Further, the present invention is characterized in that the operating body is provided with a holding unit that allows the operating body to move downward when the operating body is locked, and holds the operating body in an upward moving state when the operating body is unlocked. I have. In this way, if the operating body is locked only when necessary, the holding means can move the operating body downward to prevent the door from being closed, and otherwise, the operating body is unlocked. If this is the case, the operating body can be held in the up-moved state.

  In addition, the present invention provides a rotating base, wherein the movable portion is disposed on the floor and forms substantially the same surface as the floor surface, and one end of the movable portion is rotatably supported by the base so as to form substantially the same surface as the floor surface. A plate, wherein the locking portion comprises a case attached to the door, and a magnet held in the case, wherein a part of the lock portion is accommodated in a case of the locking portion, When the door is opened, the rotating plate is attracted by the magnet, and the upper end of the rotating plate is moved upward and locked on the inner wall of the case, thereby preventing the opening of the door.

  With this configuration, the base body and the rotating plate of the movable portion do not protrude from the floor surface, do not hinder the cleaning of the floor surface, do not get caught by the feet, and have a very compact configuration.

  As described above, according to the first aspect of the present invention, the movable portion may be structured to be attracted by the magnet and locked to the locking portion. It is possible to prevent the part from protruding from the floor, and conversely, embed the magnet of the locking part on the floor surface, and move the movable part so that it is movable only when the magnet is attracted and locked to the locking part. Even when installed on the door side, it is possible to prevent the magnet of the locking part from protruding from the floor surface, so it is very compact so that it does not interfere with cleaning the floor surface or get caught by feet A door stopper having the configuration can be provided.

  Further, when the lock is operated while the door is held open, the door can be prevented from being closed by the lock. Therefore, an external force acts on the door in the closing direction by a simple operation. Even if it is applied to a door at the entrance, it can prevent the door from being closed by a strong wind, making it easy to take in and out of luggage. It is very convenient.

  According to the second aspect of the present invention, it is possible to prevent or release the closing of the door by the operating body by performing the locking operation or the unlocking operation of the operating body. Therefore, it is not necessary to bend or bend over the waist, and it is possible to prevent and release the blocking of the door by a simple operation.

  According to the third aspect of the present invention, since the operating body may be provided vertically below the door so as to be vertically movable, it is possible to realize a compact configuration.

  According to the fourth aspect of the present invention, the operating body is locked only when necessary, whereby the operating body can be moved downward by the holding means, and the closing of the door can be prevented. In other cases, if the operating body is unlocked, the operating body can be held in the upward movement state.

  According to the fifth aspect of the present invention, the base of the movable portion does not protrude from the floor surface, does not interfere with the cleaning of the floor surface, does not get caught by the foot, and has a very compact configuration. It becomes.

  One 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 operation in a separated state. is there.

  As shown in these figures, a locking portion 10 of a door stopper is attached to a lower corner of the other end of the door 1 whose one end is rotatably supported by a hinge, and the degree of opening of the door 1 is almost fully opened ( For example, the movable portion 30 of the door stopper is buried on the floor surface below the locking portion 10 when the angle 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 has a substantially square plate-shaped main part 12 which is directly screwed to the door 1 and a cover having an open lower surface which is attached to the main part 12 so as to cover a part except for the left end of the main part 12. 13. Reference numeral 14 denotes a plurality of screw insertion holes formed in the main part 12.

  A magnet space 15 for accommodating the magnet 25 is formed in a lower right portion in the cover 13, and a boss 16 inserted in a through hole 26 in the center of the magnet 25 and supporting the magnet 25 is integrally formed inside the cover 13. It has been planted in. As shown in FIGS. 1 and 3, the magnet 25 includes a rectangular parallelepiped magnet main body 27 and two rectangular yoke plates 28 disposed so as to sandwich the magnet main body 27. ing.

  In the left end surface of the cover 13, a rectangular through hole 17 through which the operating body 41 constituting the lock portion 40 is inserted is formed. Further, an operating body space 18 in which an operating body 45 constituting the lock portion 40 is vertically movably housed is formed at a position near the left end in the cover 13. Further, at the lower end of the main portion 12, a left and right long locking body 19 having an L-shaped cross section whose upper end protrudes forward is integrally formed, and a step portion 20 of the locking body 19 has a movable portion 30 described later. Of the rotating plate comes into contact with each other.

  Next, as shown in FIGS. 1, 2, and 5, the movable portion 30 is formed on the rectangular thin base 31 disposed at a predetermined position on the floor and screwed, and formed on the base 31. A rectangular recess 32 and a rotating plate 34, which is disposed in the recess 32 and has a rolled front end rotatably supported via a support shaft 33, are formed, and the base 31 is thin. The base 31 hardly protrudes from the floor and forms substantially the same plane as the floor, and the rotating plate 34 also forms the same plane as the upper surface of the base 31 when not attracted by the magnet 25, and is substantially flush with the floor. Make

Here, at the left end of the rotating plate 34, an oval-shaped through hole 35 into which the lower end of the operating body 45 is removably inserted is formed. The lock portion 40 is configured together with the body 45 and a spring described later. Reference numeral 37 denotes a plurality of screw insertion holes for fixing the base 31 to the floor.

  Accordingly, 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 of the rotating plate 34 moves upward to lock the locking member 19. The door 1 is held in the open state because the contact of the door 1 with the step portion 20 is prevented, and further the opening of the door 1 is prevented, and the suction state of the rotating plate 34 by the magnet 25 is maintained. On the other hand, to close the door 1 from this state, a slight force is applied to the door 1 in the closing direction (see FIG. 6), whereby 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, the operating body 41 of the lock portion 40 has an L-shape in plan view, as shown particularly in FIGS. 1, 4 and 6, and has a wide left end extending from the through hole 17 of the cover 13 to the outside. The right end is rotatably 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, the operating body 45 of the lock portion 40 has an upper end portion 45 a and a lower half portion 45 b having a columnar shape, and a rectangular parallelepiped located between the upper end portion 45 a and the lower half portion 45 b. The spiral spring 46 is wound around the upper end portion 45a of the operating body 45, and both ends of the spring 46 are connected to the upper inner surface of the cover 13 in the operating body space 18 and the engaging portion of the operating body 45. The operating body 45 is urged downward via the engaging portions 45c, each being locked on the upper surface of 45c. At this time, the operating body 45 is arranged so that the lower end face of the operating body 45 in the downward movement state is located slightly above the upper surfaces of the rotating plate 34 and the base 31 in a state before being attracted by the magnet 25. It is desirable to do.

  Incidentally, a boss 42 (see FIG. 1) is integrally formed substantially at the center of the operating body 41, and the operating body 41 is inserted into a vertically long slot 47 formed at the center of the engaging portion 45c of the operating body 45. A boss 42 of 41 is loosely inserted and engaged, and the operating body 41 rotates about the boss 22. When the left end 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 elongated hole 47, and the operating body 45 moves upward against the spring 46 as described later in detail. Held in state. On the other hand, when the left end 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, the right end of the operating body 41 is engaged with a leaf spring 49 as a holding means in the cover 13 as shown in FIG. 1, and this leaf spring 49 has a substantially concave shape. Is locked by a locking portion on the inner surface on the right side of the cover 13, the central portion projects 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 open by the suction of the rotating plate 34 by the magnet 25, the lock operation of the operating body 41, that is, when the left end of the operating body 41 is pushed down, the right end of the operating body 41 Slides upward from the bottom of the curved portion of the leaf spring 49, and the operating body 45 is moved downward by the bias of the spring 46, so that 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 operation 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 lock operation has been performed.

  Further, since the left end of the operating body 41 abuts on the lower surface of the through hole 17, the pressing down of the left end of the operating body 41 is restricted, so that the right end of the operating body 41 stops at a position over the curved portion, The lower end of the operating body 45 is held in a state of being inserted into the through hole 35 of the rotating plate 34 to be in a locked state, and the closing of the door 1 is prevented 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 is opposed to the spring 46 while the boss 42 of the operating body 41 is in contact with the upper surface of the elongated hole 47. When the operating body 45 is pushed up, the lower end of the operating body 45 comes out of the through hole 35 of the rotating plate 34, the locked state is released (unlocked state), and the operating body 45 is held in the upward moving state.

  At this time, the right end of the operating body 41 slides on the curved portion of the leaf spring 49 from top to bottom. When the right end of the operating body 41 gets over the curved portion, the operating force of the operating body 41 is applied by the spring force of the leaf spring 49. It is desirable to set the spring force of each of the leaf spring 49 and the spring 46 such that the clockwise moment applied to the operating body 41 exceeds the counterclockwise moment applied to the operating body 41 by the spring force of the spring 46.

  Therefore, for example, when the door 1 is opened to a substantially fully open position when applied to a door at the entrance, the rotating plate 34 of the movable portion 30 on the floor side is attracted by the magnet 25 of the locking portion 10 on the door 1 side, thereby rotating the door 1. The upper end of the plate 34 moves upward and locks on the step portion 20 of the locking body 19, thereby only opening the door 1, restricting further opening of the door 1, and simultaneously opening the door 1. , And the luggage can be taken in and out of the entrance very easily.

  On the other hand, merely holding the door 1 in the open state by attracting the rotating plate 34 by the magnet 25 in this manner causes the holding force of the door 1 by the attraction of the magnet 25 to the door 1 such as a strong wind blowing. When an external force exceeding the above is applied in the closing direction of the door 1, the magnet 25 of the door 1 may release the suction of the rotating plate 34 and the door may close without permission. In such a case, when the operating body 41 is pressed down, the operating body 45 moves down against the spring 46 and its lower end is inserted into the through hole 35 of the rotating plate 34, so that the user bends the waist. It is possible to prevent the door 1 from being closed by a strong wind or the like by a simple operation without performing a special operation such as hooking and hooking a hook.

  Further, 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 face is located slightly higher than the upper surfaces of the rotating plate 34 and the base 31, the rotating plate 34 is attracted by the magnet 25 and the rear end of the rotating plate 34 tends to move upward. The lower end of the operating body 45 slides on the upper surface of the rotary plate 34 until the lower end of the rotary member 45 is fitted into the through hole 35 of the rotary plate 34. Therefore, the opening of the door 1 can be continued without causing any damage to the members until the lower end of the operating body 45 fits into the through hole 35, and the lower end of the operating body 45 fits into the through hole 35. At the same time, the rear end of the rotating plate 34 is moved upward and locked to the stepped portion 20 of the locking body 19, so that the opening of the door 1 is restricted and the door 1 can be locked in the open state.

  Therefore, according to the above-described embodiment, the movable portion 30 does not greatly protrude from the floor as in the related art, and the rotating plate 34 forms substantially the same surface as the floor surface in a normal state. The appearance is good without becoming bent or being caught on the foot, and the opening of the door 1 can be regulated very easily and the door 1 can be held in the open state only by opening the door 1 almost fully open. It is possible to provide a door stopper having a very compact and easy-to-handle configuration.

  Further, since the closing of the door 1 in the open state can be prevented and the locked state can be maintained by merely locking the operating body 41, that is, pushing down the operating body 41, a strong wind or other external force acts on the door 1 in the closing direction. Even if it operates, the door 1 can be securely held in the open state, which is very convenient. At this time, since the left end of the operating body 41 has a structure led out of the cover 13, the operating 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 allows the operating body 45 to be held in the upward moving state when the operating body 41 is unlocked. It is possible to operate the operating body 41 only when it is necessary to lock it.

  In the above-described embodiment, a case has been described in which the operating 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. Are rotatably provided so that the lower portion engages with the floor when the operating body rotates in one direction to prevent the door 1 from being closed, and the engagement is released when the operating body rotates in the other direction. You may. As the engagement in this case, a mode in which the tip of the hook-shaped operating body is engaged with the engagement portion provided on the floor side is considered.

  Further, the operation body itself may be configured to engage with the floor side by a lock operation and an unlock operation of the operation body provided on 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 described. Conversely, the locking portion made of the magnet is movable on the floor side. It goes without saying that the part may be provided on the door side.

  Further, a push button and an engaging member protruding from the floor surface toward the door by pushing the push button are respectively provided on the floor so as to be freely retractable, and the engaging member is engaged with the door to open the door. Of course, it may be locked or unlocked.

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

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

It is a front view of one embodiment of the present invention. It is a left view of one embodiment of the present invention. It is a right view of one embodiment of the present invention. It is a top view of one Embodiment of this invention. It is a top view of one part of one Embodiment of this invention.
