Description

  The present invention relates to a door stop. More specifically, it is a door stop that fixes the door in the fully open position by adsorbing the door side magnet and the magnetic plate installed on the floor so as to be swingable. It relates to doors that can be locked.

  Conventionally, as shown in FIGS. 15 to 16, in order to prevent the door 50 or knob 51 from colliding with a wall or furniture around the door 50, the cabinet 52, etc. by opening and closing the door 50, the door stop 53 is prevented. Is provided on the floor 54 in the vicinity of the door 50.

  The door stop 53 includes a base portion 55 screwed to a male screw (not shown) standing on a floor 54 and a buffer body 56 fixed to the upper portion of the base portion 55.

  Further, in order to keep the door 50 open, the U-shaped stopper 57 inserted into the base portion 55 is pulled out and engaged with the flange portion 59 of the hooked washer 58 provided on the side surface of the door 50. I try to stop.

  However, since the door stop 53 is always erected on the floor 54, if the door 50 is not fixed to the door stop 53, there is a possibility that the door stop 53 may be accidentally kicked by the door stop 53 during walking. is there.

  Moreover, when moving a conveyed product, for example, the cabinet 52, it becomes obstructive, and if the cabinet 52 accidentally collides with the door stop 53, the cabinet 52 may be dented or the door stop 53 may be deformed. Furthermore, it was in the way when cleaning the floor.

  Furthermore, since the conventional door stop 53 is erected on the floor 54 at all times, it appears that foreign matter protrudes on the floor 54, which is not preferable from an aesthetic point of view.

  On the other hand, various types of doors that can be moved in and out from the floor have been studied, and conventionally known doors that can move in and out include a door using a magnet. The door stop using the magnets described in Japanese Patent No. 2990601 and Japanese Patent Application Laid-Open No. 10-1155139 is, for example, to adsorb a magnetic material plate swingably installed on the floor surface to the door-side magnet. The door is fixed in the fully open position.

  However, since the door has a relatively large surface area, if a strong force is applied to the door by wind, the door cannot be held in the fully open position only by the attractive force between the magnet and the plate. There is a problem such as closing well.

  The present invention has been made in order to solve such a problem, and it is a door stop that fixes a door in a fully open position by adsorbing a door side magnet and a magnetic plate swingably installed on a floor surface. Then, it aims at providing the door stop which can lock a door to a full open position easily and reliably.

The door stop of the present invention includes (a) a pedestal fixed to the floor surface,
(B) a plate made of a magnetic material and attached to the pedestal so as to be swingable up and down ;
(D) a magnet body provided on the lower surface of the case;
(E) a door stop having an operating member provided at the upper part of the case ,
At least a portion of the plate is engageable with the lower surface of the case ;
A lock mechanism that protrudes from the lower surface of the case so as to freely protrude and engage with a through-hole formed in the plate, and a claw formed at a lower end of the protrusion member ;
The operating member is provided with a lifting mechanism capable of locking and unlocking at a lower position,
By pushing down the operation member, the operation member is locked at a lower position, and the protruding member is protruded from the lower surface of the case,
The operation member is pushed down again to release the lock at the lower position of the operation member, and the protruding member moves upward from a state of protruding from the lower surface of the case .

  According to the present invention, a door mechanism for swinging the plate on the floor by the attractive force of the magnet and a lock mechanism for detachably engaging the plate with the lower surface of the magnet are provided, so that the door can be easily and reliably mounted. It can be locked in the fully open position. Therefore, since the problem of closing unexpectedly even if the wind hits the door D is eliminated, the door of a high-rise apartment where a strong wind easily hits can be easily and reliably locked in the fully opened position.

  Further, when the door stop is not used, the plate of the main body portion is almost flush with the floor surface, so that the transported object such as walking or cabinet can be stably moved.

  In addition, when the door is not fully opened, the plate is substantially flush with the floor surface, so that the floor surface around the door is flat and the aesthetics can be improved. In addition, it is possible to design the exterior around the entrance, taking advantage of the flatness of the floor.

  The door stop shown in FIG. 1 is mainly composed of a main body portion 1 installed on the floor surface and a magnet 2 fixed to the door D.

  As shown in FIGS. 1 and 8, the main body portion 1 has a plate 4 made of a magnetic material such as iron swingably attached to a pedestal 3 made of zinc alloy or the like fixed to the floor surface with screws or the like. ing. The installation method of the main body portion 1 is not particularly limited in the present invention, and may be installed on the floor as shown in FIG. 1 or may be embedded in a buried hole formed in the floor.

  In FIG. 8, the plate 4 whose upper surface side is shown in (a) and whose lower surface side is shown in (b) is formed by processing a thin iron plate. Since the front end 4a of the plate 4 is folded back to the lower surface and the side edges 4b are bent downward at a right angle (see FIG. 9), the rigidity of the entire plate 4 is greatly improved.

  In addition, the pair of bearing portions 4 c are integrally formed with the plate 4 by winding the rear end of the plate 4 in a rearward direction. A round bar-shaped rotating shaft 4d is inserted into the bearing portion 4c.

  The pedestal 3 is formed with a rectangular opening 3 a that accommodates the plate 4. The plate 4 is inserted into the opening 3a of the base 3 from below, and both ends of the rotating shaft 4d are rotatably inserted into a pair of bearing recesses 3b opened downward.

  As shown in FIG. 8B, the pair of bearing recesses 3b are closed by a shaft pressing plate 3c fixed to the lower surface of the base 3 with screws or the like, so that the rotating shaft 4d is the bearing recess 3b of the base 3. There is no worry about falling off. In addition, a projecting piece 3d is projected forward from the central portion of the shaft pressing plate 3c. The projecting piece 3d prevents the plate 4 from dropping downward and supports the rotating shaft 4d from below. Further, a rib is formed at the tip of the projecting piece 3d in parallel with the rotating shaft 4d, and the plate 4 can resist the force in the direction away from the rotating shaft 4d.

  Further, the plate 4 is formed with a rectangular engagement hole 5 that engages with a protruding member 9 that appears and disappears on the lower surface of the magnet 2 on the door D side described later. In the present embodiment, the shape of the engagement hole 5 and the cross-sectional shape of the later-described protruding member 9 that engages with the engagement hole 5 are described by taking a rectangular shape as an example. However, the engaging hole 5 may be a round hole and the protruding member 9 may be a cylinder.

  As shown in FIGS. 1 to 3, the magnet 2 includes a case 6 fixed to the lower surface of the door D with a screw or the like, and a pair of magnet bodies 7 embedded so as to slightly protrude from the lower surface of the case 6, An operation member 8 inserted into the upper part of the case 6 so as to be movable up and down, a substantially square columnar protruding member 9 fixed to the operation member 8 and inserted into the through hole 6a of the case 6 so as to be movable up and down, and the case 6 A compression coil spring 10 that is housed inside and biases the operation member 8 and the protruding member 9 upward, and a back cover 11 that covers the back surface of the case 6.

  The lower surface 6c of the case 6 is inclined so as to rise as it goes rearward, so that the plate 4 and the magnet body 7 swinging upward can be brought into close surface contact with each other. Further, a portion 6b extending downward along the door D is formed at the back end of the lower surface 6c of the case 6, and the tip of the plate 4 attracted to the magnet body 7 collides with the portion 6b. It is like that. The portion 6b of the case 6 is preferably made of a synthetic resin or has rubber or the like attached to the surface so as to be able to absorb the impact at the time of collision with the plate 4.

  In the present embodiment, the locking mechanism for locking the plate 4 to the lower surface of the magnet 2 (that is, the lower surface 6 c of the case 6) is composed of a protruding member 9. A claw 9 a is formed at the lower end of the protruding member 9 so as to be easily engaged with the engagement hole 5 of the plate 4. Further, the lower surface 9b of the protruding member 9 is inclined so as to descend toward the rear so that the claw 9a can easily slide on the surface of the plate 4 and engage with the engaging hole 5.

  In the present embodiment, as shown in FIGS. 2 to 3, the pair of magnet bodies 7 are disposed on both sides of the through-hole 6 a along the width direction of the case 6. The pair of magnet main bodies 7 may be arranged along the front-rear direction of the case 6 without being limited thereto.

  In the present embodiment, as shown in FIG. 3, the pair of magnet bodies 7 are arranged so as to extend in the vertical direction, but the present invention is not limited to this, and extends in the horizontal direction. You may arrange | position so that only one magnet main body 7 may extend in a horizontal direction.

  Further, the door stop according to the present embodiment includes an elevating mechanism 12 inside the back cover 11 so that the operation member 8 and the protruding member 9 can be easily locked or released at a predetermined lower position.

  As shown in FIGS. 2 and 4, the elevating mechanism 12 is provided on the rear surface of the case 6 and a locking body 13 having a locking portion 13 a rotatably attached to the rear surface of the operation member 8. An abutment body 14 capable of abutting on the engagement body 13 and an engagement body 13a of the engagement body 13 provided above the abutment body 14 on the rear surface of the case 6 And a protrusion 15.

  The elevating mechanism 12 locks the operating member 8 and the protruding member 9 as follows. First, when the pedal 16 of the operating member 8 is pushed down with the foot, the locking body 13 descends in the groove 6d formed on the rear surface of the case 6, and the contact body 14 contacts the locking body 13 and locks. The body 13 is rotated (see FIG. 5).

  After that, when the foot is released from the pedal, the operating member 8 is raised by the urging force of the compression coil spring 10, but when the locking portion 13 a of the locking body 13 is locked to the protrusion 15, the operation member 8 is moved to a predetermined lower position. (See FIG. 6). At this time, the lower end of the protruding member 9 protrudes slightly downward from the case 6 (see FIG. 9).

  Further, when the operation member 8 is pushed down again with the foot, the contact member 14 further rotates the locking body 13 as shown in FIG. 7, whereby the operation member 8 can be unlocked.

  Also, as shown in FIGS. 4 to 7, the protrusion 8 a that protrudes from the rear surface of the operation member 8 is inserted into a slit 6 g that is formed on the rear surface of the case 6 and extends in the vertical direction. Can move up and down approximately the length of the slit 8a, but does not fall out of the case 6.

  When using the door stop of the present embodiment, as shown in FIG. 9, first, the pedal 16 of the magnet 2 is stepped on with a foot, the protruding member 9 is protruded downward and locked, and in this locked state, the door D To the fully open position.

  When the door D reaches the fully open position, as shown in FIG. 10, the plate 4 swings upward and is attracted to the lower surface of the magnet 2, and the protruding member 9 is engaged with the engagement hole 5 of the plate 4. Match. As a result, the door D is easily and reliably locked in the fully open position, and does not close unexpectedly even if wind hits the door D.

  On the other hand, when it is desired to release the lock of the door D, if the pedal 16 is stepped again with the foot, the protruding member 9 moves upward and the lock is released. Therefore, after the lock is released, the door D is easily closed. be able to.

  Even in the unlocked state, if the door D is opened to the fully open position, the plate 4 is attracted to the magnet 2, so that the door D is held in the fully open position with a weak force. Therefore, it is convenient when it is desired to temporarily hold the door D in the fully open position, such as when carrying in a package.

  The door stop shown in FIGS. 1 to 10 locks the door D when the protruding member 9 of the magnet 2 engages with the engagement hole 5 of the plate 4. Without being limited, as an opposite example, a projection for locking the door D may be provided on the plate 4 side.

  That is, as another embodiment of the present invention, in the door stop shown in FIGS. 11 to 12, the lock mechanism is formed on the upper surface of the plate 4, and the through hole 6 a formed on the lower surface 6 c of the case 6 of the magnet 2. It is comprised from the protrusion 17 which can be engaged, and the protrusion member 9 which is a plate press part which pushes down the plate 4 below. The door stop shown in FIGS. 11-12 differs from the door stop shown in FIGS. 1-10 by the point which provided the protrusion 17 instead of forming the engagement hole in the plate 4, About another structure, FIG. 10 to 10 are common to the door stops shown in FIG.

  The protrusion 17 on the plate 4 is formed with a slope in a downward direction as it approaches the door D so that the lower surface 6c of the case 6 on the magnet 2 side can easily slide.

  11-12, when the door D is opened to the fully open position with the protruding member 9 raised, the plate 4 swings upward and is attracted to the lower surface of the magnet 2, and the projection 17 engages with the through hole 6 a of the case 6. As a result, the door D is easily and reliably locked in the fully open position, and does not close unexpectedly even if wind hits the door D.

  On the other hand, when the door D is to be unlocked, if the foot 16 is depressed, the protruding member 9 moves downward and the plate 4 is pushed down to release the lock. Can be easily closed.

  In the door stop shown in FIGS. 11 to 12, the magnet 2 is described as an example in which the protruding member 9 protrudes and protrudes inside the through hole 6 a, but the present invention is not limited to this, and the magnet 2. As long as a concave portion that can be engaged with the protrusion 17 is formed on the lower surface of the plate and either the magnet 2 or the plate 4 is provided with a plate pressing portion that pushes the plate 4 downward, various modes can be adopted. For example, as the plate pressing portion, a lever provided on the magnet 2 or a pedal extending in the width direction of the plate 4 (perpendicular to the plane of FIG. 12) may be employed instead of the protruding member 9.

  As still another embodiment of the present invention, in the door stop shown in FIGS. 13 to 14, the lock mechanism extends in the width direction of the plate 4 from the peripheral surface of the plate 4, and the lower surface 6 c of the case 6 of the magnet 2. Are formed of a widthwise protrusion 19 that fits into the recessed portion 18 formed in the projection 18 and a protruding member 9 that is a plate pressing portion that pushes the plate 4 downward. The other configurations are shown in FIGS. The door stop has the same configuration as that shown in FIGS. 1 to 10 except that the plate 4 does not have an engagement hole.

  The plate 4 shown in FIG. 13B has a trapezoidal shape as a whole by integrally forming a pair of widthwise protrusions 19 on the side surface of the plate 4. Accordingly, the strength of the width direction protrusion 19 is increased and the molding is easy.

  Further, the concave portion 18 formed on the lower surface 6c of the case 6 of the magnet 2 is a trapezoidal shape complementary to the plate 4 so that the concave portion 18 can be fitted to the tip portion of the plate 4 together with the pair of widthwise protrusions 19. Presents.

  Further, as shown in FIGS. 13A and 14, the pair of width direction protrusions 19 of the plate 4 can easily get over the lower edge of the front surface 6 e of the case 6 on both side edges of the concave portion 18 of the lower surface 6 c. Thus, a slope (slope) 6f is formed.

  13 to 14, when the door D is opened to the fully open position with the protruding member 9 raised, the plate 4 swings upward and is attracted to the lower surface of the magnet 2. The entire plate 4 including the width direction protrusion 19 is fitted in the recess 18 of the case 6. As a result, the door D is easily and reliably locked in the fully open position, and does not close unexpectedly even if wind hits the door D.

  On the other hand, when the door D is to be unlocked, if the pedal 16 (see FIG. 9) is stepped on with the foot, the protruding member 9 moves downward and the plate 4 is pushed down to release the lock. After that, the door D can be easily closed.

  13 to 14, the plate 4 including the pair of widthwise protrusions 19 and the concave portion 18 on the magnet 2 side are trapezoidal, but the present invention is not limited to this, and the plate 4 Any aspect can be adopted as long as the door D can be locked by engaging the widthwise protrusion 19 on the side with the recess 18 on the magnet 2 side.

  In the door stop shown in FIGS. 13 to 14, as in the door stop shown in FIGS. 11 to 12, the magnet 2 is described as an example in which the protruding member 9 appears and disappears inside the through hole 6 a. The present invention is not limited to this, and a concave portion 18 in which the widthwise projection 19 can be engaged is formed on the lower surface of the magnet 2, and a plate pressing portion that pushes the plate 4 downward on either the magnet 2 or the plate 4. If it is provided, various aspects can be employ | adopted. For example, as the plate pressing portion, a lever provided on the magnet 2 or a pedal extending in the width direction of the plate 4 (perpendicular to the plane of FIG. 12) may be employed instead of the protruding member 9.
