[0013]
The door stop shown in FIG. 1 is mainly composed of a main body portion 1 installed on a floor surface, a magnet 2 housed in a door D, and an operation unit 3.
[0014]
As shown in FIG. 1 and FIG. 2, the main body portion 1 is made of a magnetic material such as iron or steel on a base 4 made of engineering resin such as nylon or polyacetal, zinc alloy, etc. fixed to the floor surface with screws. The plate 5 is attached so as to be swingable about the rotation shaft 5a. A lower protrusion 5 b that protrudes downward is provided at the tip of the plate 5. The installation method of the main-body part 1 is not specifically limited in this invention, You may install in a floor surface as FIG. 1 shows, or you may embed in the embedding hole formed in a floor. .
[0015]
The magnet 2 and the operation unit 3 are set to be thinner than the thickness of the door D so that the magnet 2 and the operation unit 3 can be accommodated in the door D.
[0016]
As shown in FIG. 3, the magnet 2 includes a casing 6, a magnet body 7, a hook 8 that engages with the plate 5, a compression coil spring 9 that biases the hook 8 in a direction to engage with the plate 5, and a hook 8. Are combined with a horizontal slide member 10 for locking at a position engaged with the plate 5.
[0017]
The magnet body 7 is made of a permanent magnet and is housed inside the casing 6, and is configured to exert a magnetic force on the plate 5 through the wall of the casing 6.
[0018]
As shown in FIG. 2, the hook 8 has a hook portion 8 a protruding upward that can be engaged with the lower protrusion 5 b at the tip of the plate 5. An engagement protrusion 8 b that engages with the upper end of the compression coil spring 9 protrudes from the center of the hook 8. Further, on the front surface of the hook 8, a horizontal passage 8c extending in the horizontal direction (the width direction of the hook 8; the direction perpendicular to the paper in FIG. 3) is formed above the engagement protrusion 8b.
[0019]
By temporarily fixing the plate 5 using the hook 8, the door D can be temporarily fixed easily and reliably regardless of the strength of the magnet 2. In a state where the plate 5 is attracted to the magnet 2 by the hook 8, the hook 8 can move downward against the urging force of the compression coil spring 9, so that the plate 5 has a weak locking force that can be pulled out. Temporarily locked to the magnet.
[0020]
The horizontal slide member 10 is slidably accommodated in a recess 6 b formed in the casing 6 of the magnet 2. The horizontal slide member 10 is provided with at least one convex portion 11. The protrusion 11 can be locked so that the hook 8 cannot be lowered from the state in which the hook 8 is engaged with the plate 5 by moving into the horizontal passage 8 c of the hook 8.
[0021]
Specifically, as shown in FIG. 4A, when the hook 8 is not engaged with the plate 5, the horizontal passage 8 c of the hook 8 is positioned higher than the convex portion 11 of the horizontal slide member 10. Therefore, the horizontal movement of the horizontal slide member 10 and the operation of the operation unit 3 are prohibited. At this time, the height of the center of the horizontal passage 8 c only needs to be slightly higher than the height of the center of the convex portion 11, and the entire horizontal passage 8 c may not be higher than the convex portion 11.
[0022]
Next, as shown in FIG. 4B, when the hook 8 is engaged with the plate 5 (see FIG. 11), the hook 8 is lowered, and the horizontal passage 8c of the hook 8 is protruded from the horizontal slide member 10. By being almost the same height as the portion 11, the horizontal slide member 10 is slidable.
[0023]
In a state where the horizontal slide member 10 is slidable, as shown in FIG. 4C, the operation unit 3 described later is operated from the outside and the horizontal slide member 10 is pressed in the horizontal direction by the operation rod 19. The convex portion 11 of the horizontal slide member 10 can be moved into the horizontal passage 8 c of the hook 8. Thereby, the hook 8 can be locked at a position engaged with the plate 5.
[0024]
In the door stop of the present invention, since the hook 8 performs both temporary fixing and strong locking of the door, there is no need to separately provide a temporary fixing mechanism and a locking mechanism as in the prior art, and the entire apparatus can be downsized. Is possible.
[0025]
Further, in the present embodiment, as shown in FIG. 3, since the compression coil spring 12 for returning the horizontal slide member 10 to the original position is provided inside the recess 6b of the casing 6, the horizontal slide member When 10 no longer receives the operating force from the operating rod 19, as shown in FIG. 4 (b), the convex portion 11 can be returned to the position where it is out of the horizontal passage 8c.
[0026]
In the present embodiment, an example in which the operation unit 3 is arranged on the left side of the magnet 2 like a right-open door D as shown in FIG. 1 is described, but the present invention is not limited to this. For example, by disposing the operation unit 3 of the magnet 2 on the right side, the left opening door (not shown) can be used similarly to the right opening door D described above. Moreover, in the door stop of this Embodiment, since the convex part 11 is provided in both sides of the horizontal channel | path 8c as FIG. 4 shows so that it can respond even when the door D opens left and right. Even if the horizontal slide member 10 is pressed from either the left or right direction by the operating rod 19, the protrusion 11 can be moved into the horizontal passage 8c to lock the hook 8. Accordingly, not only when the operation unit 3 is arranged on the left side of the magnet 2 as in the right-opening door D as shown in FIG. 1, but also on the right side of the magnet 2 as in the left-opening door (not shown). Even when 3 is arranged, the hook 8 can be locked and released by operating the operation unit 3 from the outside.
[0027]
The operation unit 3 is for pushing the horizontal slide member 10 of the magnet 2 from the outside to the lock position (see FIG. 4C). In the operation unit 3 shown in FIG. 1 and FIGS. The lock button 16 and the lock release button 17 protrude to the outside from the opening of the outer surface 15 a exposed to the outside from the side surface of the door D of the casing 15, and the through hole 18 a of the back cover 18 on the inner back surface side of the casing 15. The operating rod 19 protrudes through.
[0028]
Specifically, as shown in FIGS. 5 to 6, the operation unit 3 according to the present embodiment is provided with an operation rod 19 for pressing the horizontal slide member 10 in the horizontal direction and a tongue piece 20. A lock button 16 that is pushed to extend the operation rod 19; a compression coil spring 21 that is a lock button urging means that applies a urging force to the lock button 16 in a direction opposite to the direction of the push operation; The swing arm 22 that is an operating rod biasing means that imparts a biasing force to the direction opposite to the direction of the pushing operation to 19, the torsion coil spring 23 that applies a rotational biasing force to the swing arm 22, and the lock button 16 to a predetermined locking position. A slidable slide plate 25 provided with a claw 24 that engages the tongue 20 of the lock button 16 when pressed, and the slide plate A compression coil spring 26 which is a slide plate urging means for applying a biasing force in a direction in which the claw 24 engages the tongue piece 20, and the slide plate 25 causes the claw 24 to release the engagement with the tongue piece 20. For this purpose, the lock release button 17 is operated to be pushed, and a compression coil spring 27 which is a lock release button urging means for applying an urging force to the lock release button 17 in a direction opposite to the push operation. The slide plate 25 is formed with a substantially rectangular through hole 25a (see FIGS. 5 to 6) for allowing the operation rod 19 to pass therethrough. The swing arm 22 is rotatably supported by a support shaft 30 supported at both ends on the side wall of the casing 15, and is pressed against the lock button 16 side by a torsion coil spring 23 attached to the support shaft 30. Note that the upper end surface 17a (see FIG. 6) of the lock release button 17 is colored with red or the like in order to make it easy to see whether or not the lock button 16 is depressed, that is, whether or not the door is locked. Also good.
[0029]
As shown in FIG. 7, the operating rod 19 is engaged with the groove 19b of the pedestal 19a so that the tip 22a of the swing arm 22 is engaged. Can reciprocate up and down. Note that the engagement between the tip 22a and the groove 19b does not hinder the vertical movement of the operating rod 19 because the groove 19b has a circumferential surface. The pedestal 19a of the operation rod 19 is accommodated in the recess 16a (see FIG. 8) of the lock button 16.
[0030]
In the slide plate 25 of the present embodiment, as shown in FIGS. 9 to 10, the claw 24 for engaging the metal tongue piece 20 made of steel or the like protruding from the lock button 16 is provided on one surface. Projected from. Slopes 28 are formed on both sides of the claw 24. Since the slope 28 of the slide plate 25 is in surface contact with the slope 29 (see FIG. 8) formed on the lock release button 17, the direction of the pressing force applied to the lock release button 17 from the outside is determined by the slide plate 25. The claw 24 can be converted from the tongue piece 20 in the direction of releasing the engagement.
[0031]
Below, an example of the usage method per door of this Embodiment is demonstrated.
[0032]
In the initial state shown in FIG. 1 and FIG. 4A, that is, in a state where the hook 8 is not engaged with the plate 5, the horizontal passage 8 c of the hook 8 is at a position higher than the convex portion 11 of the horizontal slide member 10. Thus, the horizontal movement of the horizontal slide member 10 and the operation of the operation unit 3 are prohibited. Thereby, before the plate 5 is attracted | sucked to the magnet 2, the malfunctioning of the operation part 3 (specifically locking the hook 8 accidentally by the horizontal slide member 10) can be prevented reliably.
[0033]
Next, as shown in FIG. 11, when the door D is temporarily fixed, if the door D is opened as it is from the state of FIG. 1, the plate 5 lying on the floor is attached to the magnet body 7 in the magnet 2. It rises by magnetic force and is attracted to the lower surface of the magnet 2. At the same time, the lower protrusion 5b provided at the tip of the plate 5 is engaged with the hook portion 8a of the hook 8, so that the door D can be temporarily fixed easily and reliably. 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.
[0034]
In addition, in the state shown in FIG. 11, the hook 8 moves slightly downward, so that the horizontal passage 8 c of the hook 8 becomes substantially the same height as the convex portion 11 of the horizontal slide member 10, so that the horizontal slide member 10 is It becomes possible to slide.
[0035]
When releasing the temporary fixing of the door D, the door 5 is simply closed from the state of FIG. 11, and the plate 5 is released from the lower surface of the magnet 2 while being disengaged from the hook 8. Temporary fixing is released.
[0036]
Even if the door D is not temporarily fixed by the hook 8, if the door D is opened to the fully open position, the plate 5 is attracted to the magnet 2, so that the door D is held at the fully open position with a weak force. The door D can be temporarily fixed with an even weaker holding force.
[0037]
On the other hand, when the door D is to be locked firmly in the open state such as when strong wind is blowing, if the lock button 16 is pushed with a finger as shown in FIG. 6, the operation rod 19 and the torsion coil spring 23 are urged. The swing arm 22 moves to the inner back side of the casing 15. When the lock button 16 is pushed to a predetermined lock position, the tongue 20 of the lock button 16 is engaged with the claw 24 of the slide plate 25, so that the lock button 16, the operation rod 19 and the swing arm 22 are locked. Stop at position.
[0038]
When the operating rod 19 protrudes as shown in FIG. 6, the operating rod 19 protrudes, and as shown in FIG. 4C, by pressing the horizontal slide member 10 in the horizontal direction by the operating rod 19, The convex portion 11 of the horizontal slide member 10 can be moved into the horizontal passage 8 c of the hook 8, and the hook 8 can be firmly locked at a position where it is engaged with the plate 5. As a result, the door D is easily and reliably locked in the fully opened position, and does not close unexpectedly even if wind hits the door D.
[0039]
On the other hand, when it is desired to unlock the door D, if the lock release button 17 is pressed with a finger from the state shown in FIG. 6, the slope 29 of the lock release button 17 as shown in FIGS. By pressing the slope 28 of the slide plate 25, the slide plate 25 is moved downward in FIG. 6, and as a result, the engagement between the claw 24 and the tongue piece 20 can be released. Thereby, the operating rod 19 is returned to the initial position of FIG. 5 by the urging force of the torsion coil spring 23 via the swing arm 22, and the lock of the hook 8 is released. The lock button 16, the lock release button 17 and the slide plate 25 are also returned to their initial positions by the urging forces of the return compression coil springs 21, 27 and 26, respectively.
[0040]
After the hook 8 is unlocked, the door D returns to the temporarily fixed state shown in FIG. 11, so that the door D can be easily closed by applying a slight force. When the door D is closed, since the plate 5 is pulled out from the hook 8, the hook 8 moves slightly upward and returns to the state shown in FIG. 4A. Therefore, the horizontal movement of the horizontal slide member 10 and the lock button 16 are performed. Cannot be operated.
[0041]
In the above embodiment, the door stop provided with the temporary fixing mechanism and the lock mechanism has been described as an example, but the present invention is not limited to this, and the door stop provided only with the temporary fixing mechanism. It may be. That is, the door stop according to another embodiment of the present invention includes (a) a base 4 fixed to the floor surface, and (b) a magnetic body, and is attached to the base 4 so as to be swingable up and down. A plate 5; (c) a magnet 2 fixed to the door; (d) a hook 8 attached to the magnet 2 and engaged with the plate 5; and (e) an engagement of the hook 8 with the plate 5.
