Description

  The present invention relates to a door stop. More specifically, the present invention relates to a door stop that can fix a door in a fully open position by adsorbing a door-side magnet and a plate made of a magnetic material swingably installed on a floor surface.

  Conventionally, as shown in FIGS. 14 to 15, the door 50 or the knob 51 collides with a wall or furniture around the door 50, the cabinet 52, and the like due to opening and closing of the door 50, and 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, the door stop 53 may be accidentally kicked by the door stop 53 during walking. .

  Moreover, when moving a conveyed product, for example, the cabinet 52, when 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 Patent Document 1 and Patent Document 2 is, for example, by adsorbing a magnetic plate, which is swingably installed on the floor surface, to a magnet on the door side so that the door is fully opened. It is fixed.

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

  In addition, it is conceivable to project a rod on the lower surface of the magnet so that the door can be temporarily fixed at the open position, and to form a recess or a through hole for engaging the rod on the magnetic plate. The rod must ride on the front edge of the plate attracted by the magnet and engage with the concave portion or the through hole, which makes it difficult to reliably engage the rod.

  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. Another object of the present invention is to provide a door stop that can easily and reliably lock the door in the fully open position and can reliably engage the plate.

Doorstop of the present invention includes a base fixed to the floor, a plate pivotally mounted on said base, a casing fixed to the vicinity of the lower end portion of the door is retractable accommodated in the housing A rod extending vertically, and a pressed portion connected to the rod for moving the rod up and down, and the plate is made of a magnetic material, and is provided in the housing when the rod protrudes downward. the plate claw provided at the lower end of the rod is engaged with the claw provided at the free end of the plate when the lifted by the resulting magnet, before Symbol pressed portion is the housing and a compression coil spring And the upper end of the rod is configured to be pivotable with respect to the pressed portion by a shaft, and the rod is horizontally disposed at the upper end side of the rod and below the shaft. Attached to engagement direction Second spring for, characterized by comprising provided between the rod and the pressed portion.

  According to the present invention, it is provided at the lower end of the rod by providing a lock mechanism for detachably engaging the plate with the lower surface of the magnet at the door stop that swings the plate on the floor by the attractive force of the magnet. Even when a strong force is applied to the rod by forcibly opening / closing the door D when the claw is engaged with a claw or recess provided at the free end of the plate, Unless the door stop is destroyed, the engagement between the claw provided at the lower end of the rod and the claw or recess provided at the free end of the plate is not released. 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.

  Moreover, since the rod is provided on the lower surface of the magnet so as to be able to protrude and retract, it can be reliably engaged with the plate.

  Further, when the door stop is not used, the plate 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.

  Next, the door stop of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory perspective view showing an embodiment of a door of the present invention, FIG. 2 is a diagram showing an embodiment of a plate used in the present invention, and FIGS. 3 (a) and 3 (b) are diagrams of the present invention.

FIGS. 12 and 13 are cross-sectional explanatory views showing a process in which the rod on the bottom surface of the magnet and the plate engage with each other according to the present invention.

  The door stop shown in FIG. 1 is roughly composed of a pedestal portion 1 installed on the floor and a housing 2 fixed to the door D and fixed near the lower end of the door. Here, the vicinity of the lower end of the door is, for example, within a range of about 10 to 20 cm from the lower end edge of the door, and the casing can be engaged with a plate provided on the floor and a rod of the casing. Provided at height.

  As shown in FIG. 1, FIG. 2 and FIG. 11, the pedestal portion 1 is made of a magnetic material such as iron on a pedestal 3 made of engineering resin such as nylon or polyacetal or zinc alloy fixed to the floor surface with screws or the like. A plate 4 is attached so as to be swingable. The installation method of the pedestal 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.

  As shown in FIGS. 11A to 11C, the pedestal portion 1 includes a pedestal 3, a plate 4, and a shaft pressing plate 3e.

The plate 4 is formed with an engaging portion that can engage with a rod 9 on the lower surface of the housing 2 to be described later. As shown in FIG. 3 (b), in the present embodiment, the engaging portion is a claw 4a provided in a convex shape below the free end of the plate 4, but the shape of the engaging portion is as shown in FIG. A through hole as shown in FIGS. 12 and 13 may be used. The engaging portion can employ a known locking mechanism such as a concave portion or a screw formed on the plate 4 in accordance with the shape of the rod engaged with the engaging portion .

  The plate 4 is made of a magnetic material such as iron or steel. For example, as shown in FIG. 3B and FIG. 11, one thin iron plate is pressed, or two or more metal plates are formed. You may laminate. For example, when a plate is produced using a plurality of metal plates, a concave portion is formed in the uppermost metal plate, and a protruding portion generated below the concave portion of the uppermost metal plate can be inserted into the lower metal plate. What is necessary is just to fix each other by forming a through-hole and caulking these metal plates.

  The shape of the through-hole which is the engaging portion 5 of the plate 4 and the claw 4a formed below the free end side end portion of the plate 4 are not particularly limited in the present invention, and correspond to the shape of the rod 9. The selection should be as follows. That is, the angle and the like of the claw 4a can be changed as appropriate, and the claw 4a can be rounded to adjust the degree of engagement.

  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 pedestal 3 from below, and the shafts 16 projecting on both sides of the rear end of the plate 4 are rotatably inserted into a pair of bearing recesses 3b opened downward.

  As shown in FIG. 11A, the pair of bearing recesses 3b are closed by the shaft pressing plate 3e that is caulked to the lower surface of the pedestal 3 or fixed by adhesion or the like, so that the shaft portion 16 is pedestal. There is no fear of dropping from the bearing recess 3b. Further, as shown in FIG. 11 (c), a projecting piece 3f is projected forward from the center of the shaft pressing plate 3e. The projecting piece 3f prevents the plate 4 from dropping downward.

  As shown in FIGS. 11, 12, and 13, the lower surface of the base 3 is provided with a contact portion 3 c that can contact the rear end of the plate 4 when the plate 4 collides with the magnet 7. Therefore, the impact received by the plate 4 when it collides with the magnet 7 can be received by the contact portion 3c, and damage to the shaft portion 16 (see FIG. 11B) of the plate 4 can be prevented.

  Further, as shown in FIGS. 11B, 12, and 13, a buffer body 20 made of a thin rubber layer or the like is provided on the lower surface of the plate 4. Therefore, when the transition from the upper position of the plate 4 shown in FIG. 13 to the lower position of the plate 4 shown in FIG. 12, the shock absorber 20 on the lower surface of the plate 4 reduces the collision between the plate 4 and the floor surface. Generation of a loud metal sound can be prevented.

  Moreover, the shaft portion 16 of the plate 4 is formed with an inclined portion 16a for restricting the swing angle of the plate 4 so as to rise toward the rear of the plate 4 (rightward in FIG. 11B). ing. Therefore, if the plate 4 swings upward to a predetermined swing angle (for example, about 30 degrees), the inclined portion 16a comes into surface contact with the lower surface of the base 3 so that the swing angle of the plate 4 is accurately regulated. be able to.

  As shown in FIGS. 1 to 3 and FIGS. 4 a to 4 d, the housing 2 includes a case 6 fixed to the lower surface of the door D with screws or the like, and a pin described later so as to slightly protrude from the lower surface of the case 6.

  In the present embodiment, an example in which a pair of magnets 7 is provided is described. However, the present invention is not limited to this, and includes one magnet having a strong magnetic force. In this case, the entire housing 2 can be made compact.

  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 7 collides with the portion 6b. It has become. 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.

  The location of the portion 6b can be changed as appropriate. In the embodiment shown in FIG. 2, the rod 9 protrudes downward at the distal end from the door D so that the rod 9 protrudes downward. It can also be provided.

  As described above, the pair of magnets 7 is provided so as to be rotatable around the pins 17 inside the case 6, so that when the plate 4 made of a magnetic material is swung upward and is attracted to the magnets 7, By slightly rotating the magnet 7 pushed by 4 (see FIG. 3), it is possible to automatically correct errors such as door play and door-to-door mounting errors, and the magnet 7 always faces the plate 4. It is possible to touch.

  In this embodiment, an example in which the magnet 7 is rotatable is shown, but the present invention is not limited to this, and the magnet 7 may be fixed to the case 6.

  In the present embodiment, the locking mechanism for locking the plate 4 to the lower surface of the magnet 7 (that is, the lower surface 6 c of the case 6) is composed of a rod 9. A claw 9 a is formed at the lower end of the rod 9 so as to be easily engaged with the engaging portion 5 of the plate 4. Further, the lower surface 9b of the rod 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 portion 5.

  Since the rod 9 is integrally attached to the pressed portion 8 so as to protrude and retract downward, it is easy to engage the engaging portion 5 of the plate 4 with the rod 9.

  Specifically, as shown in FIG. 3, the rod 9 is pivotable about an axis 9 e and can be engaged with a claw 4 a provided below the free end of the plate 4. The nail | claw 9a formed in the part is formed. In this case, in order to ensure the engagement of the rod 9, a spring 9d that is urged in the horizontal direction is provided between the rod 9 and the pressed portion 8, and the spring 9d moves the rod 9 in the engagement direction. Energized.

  Further, the rod 9 may be a gear (for example, worm wheel, pinion) in which the lower end of the rod 9 is non-rotatable, and a gear (worm, rack) that can be engaged with the rod 9 may be formed on the plate 4. It is.

  Further, as shown in FIG. 4a, as another aspect of the rod 9, the pressed portion 8 and the rod 9 can be integrally formed. In this case, as shown in FIGS. 12 and 13, an engaging portion 5 having a through hole is formed in the plate 4 that engages with the rod 9, and the engaging portion 5 and the rod 9 engage with each other.

  As shown in FIG. 4b, the rod 9 and the pressed portion 8 can be fixed by a known fixing means such as an adhesive, welding, or a screw. As another aspect, a slit 9c extending in the vertical direction of the rod 9 is formed as shown in FIG. 4c, and pins 18 having both ends fixed to the case 6 are directed in the direction perpendicular to the paper surface of FIG. 4c. Therefore, the rod 9 can move up and down by a predetermined stroke.

  The rod 9 shown in FIGS. 4b and 4c can be engaged with the engaging portion 5 shown in FIGS. 12 and 13 in the same manner as the embodiment shown in FIG. 4a.
