[0012]
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.
[0013]
As shown in FIGS. 1 and 5, the main body 1 is made of a magnetic material such as iron or steel on a base 3 made of engineering resin such as nylon or polyacetal, zinc alloy or the like, which is fixed to the floor surface with screws or the like. The plate 4 is attached so as to be swingable about the rotation shaft 4a. 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. .
[0014]
The plate 4 has a lower protrusion 7 (see FIGS. 1 and 5) that can be engaged with a hook 6 (see FIGS. 3 and 5) of a temporary fixing mechanism 5 provided on the lower side of the magnet 2 described later. It is formed by projecting the tip part of 4 downward. The lower protrusion 7 may be formed by folding the front end of the plate 4 to the lower surface side.
[0015]
Further, an engaging recess 10 that can engage with a claw 9 a (see FIGS. 3 and 5) of a stopper 9 of the lock mechanism 8 described later is formed near the center of the plate 4. The engagement recess 10 may be a part of the plate 4 that is recessed, or may be a through hole.
[0016]
As shown in FIGS. 1 to 7, the magnet 2 is set to be thinner than the door D so that the entire magnet 2 can be accommodated inside the door D. As a main part, an inner case 13 to which the magnet main body 12, the temporary fixing mechanism 5 and the lock mechanism 8 are attached is inserted from below. Furthermore, an operation button case 15 that houses the operation buttons 14 is attached to the side of the outer case 11.
[0017]
As shown in FIG. 2, the magnet 2 of the present embodiment has mounting holes 11 a for the operation buttons 14 formed on both sides of the outer case 11.

[0018]
Moreover, the magnet body 12, the temporary fixing mechanism 5 and the lock mechanism 8 attached to the inner case 13 can be finely adjusted in the height direction by rotating the height adjusting screws 31 supported on both sides inside the outer case 11. It has a possible configuration. Specifically, the height adjustment screw 31 is screwed into the height adjustment block 32 inside the inner case 13, and the pins 33 projecting at four positions of the height adjustment block 32 are provided on the upper portion of the inner case 13. A slit 34 extending obliquely is inserted so as to be guided.
[0019]
Therefore, if a screwdriver is inserted into the insertion hole 15a of the operation button case 15 from the outside of the door D and the height adjustment screw 31 is rotated, the height adjustment block 32 moves in the horizontal direction and the pin 33 is inclined. A mechanism such as the inner case 13 and the magnet main body 12 attached to the inner case 13 can be moved up and down while being guided by the slit 34 extending in the direction to finely adjust the height. Thereby, the positional relationship in the vertical direction between the claw portion 9a of the stopper 9 and the engaging recess 10 of the plate 4 can be adjusted according to the situation at the site so that reliable locking can be performed. It is preferable that the insertion hole 15a is normally sealed with a sealing member made of synthetic resin or rubber so that foreign matter does not enter.
[0020]
As shown in FIGS. 3 and 5, the lower surface 13 a of the inner case 13 is inclined so as to rise as it goes rearward, so that the plate 4 that swings upward and the magnet body 12 can come into close surface contact with each other. It is like that.

[0022]
As shown in FIG. 5, the temporary fixing mechanism 5 includes an upwardly projecting hook 6 that engages with a lower protrusion 7 of the plate 4 and a hook for temporarily fixing the plate 4 attracted to the lower surface of the magnet 2. And a compression coil spring 16 for biasing 6 upward. The temporary fixing mechanism 5 temporarily fixes the plate 4, so that the door D can be temporarily fixed easily and reliably regardless of the strength of the magnet 2. When the plate 4 is attracted to the magnet 2 by the temporary fixing mechanism 5, the plate 4 can be temporarily locked to the magnet with a weak locking force that can be pulled out.
[0023]
As shown in FIG. 5, the lock mechanism 8 locks the plate 4 locked to the temporary fixing mechanism 5 by an operation from the outside by hand or the like stronger than the locking force of the temporary fixing mechanism 5. The plate 4 is locked and released by force.
[0024]
As shown in FIG. 5, the lock mechanism 8 of the present embodiment includes the stopper 9 that is movably attached up and down, and a horizontal that can move in the horizontal direction in order to regulate the vertical position of the stopper 9. The moving member 17 (refer to FIGS. 4 to 5 and FIGS. 7 to 12) and the operation button 14 which is an operation unit for applying an operating force for horizontally moving the horizontal moving member 17 are configured.
[0025]
In the present embodiment, a claw 9 a is formed at the lower end of the stopper 9 so as to be easily engaged with the engagement recess 10 of the plate 4. Further, the lower surface 9b of the stopper 9 is inclined so as to descend toward the rear so that the claw 9a can easily engage with the engaging recess 10 by sliding on the surface of the plate 4.
[0026]
As shown in FIGS. 4 to 5, a space 18 is formed on the facing surface between the stopper 9 and the inner case 13, and a compression coil spring 19 is inserted into the space 18. Therefore, the stopper 9 is positioned so as to be stable in a state where the claw 9a protrudes downward by the biasing force of the compression coil spring 19. As shown in FIG. 5, when the stopper 9 is brought close to the plate 4 in a state of protruding from the lower surface of the inner case 13, the front end of the plate 4 is moved while the tip of the stopper 9 is temporarily retracted inside the inner case 13. The tip of the stopper 9 protrudes to the outside again and can be easily and reliably engaged with the engaging recess 10 of the plate 4 by the restoring force of the return compression coil spring 19 after riding.
[0027]
As shown in FIGS. 4 to 5 and 7, a rotating shaft 9 c extending in the thickness direction of the door D protrudes from the upper portion of the stopper 9, and a roller 20 is rotatably supported on the rotating shaft 9 c. Yes. A coupling may be inserted between the rotating shaft 9 c and the roller 20 in order to facilitate the rotation of the roller 20.
[0028]
As shown in FIGS. 4 to 5 and 7, the horizontal moving member 17 is accommodated in the inner case 13 so as to be horizontally movable, and is operated from the outside through the mounting holes 11 a and 13 b of the outer case 11 and the inner case 13. 14 is operated to move in the horizontal direction.
[0029]
As shown in FIGS. 4 and 7, the horizontal moving member 17 is formed with a groove 21 having different depths at the upper edge, and the roller 20 above the stopper 9 can roll inside the groove 21 in the groove 21. Are engaged. When the roller 20 is positioned at the deepest central portion 21a of the groove 21, the stopper 9 descends, and the claw 9a protrudes downward as shown in FIG. 5, while the shallow side portions 21b or 21c of the groove 21 protrude. When the roller 20 is positioned, the stopper 9 rises while compressing the compression coil spring 16, and the claw 9 a is retracted inside the inner case 13.
[0030]
Furthermore, the door stop of the present embodiment includes a horizontal positioning mechanism 22 so that the horizontal movement member can be easily and reliably positioned in the horizontal direction.
[0031]
As shown in FIGS. 8 to 11, the horizontal positioning mechanism 22 includes a locking body 23 having a locking portion 23 a rotatably attached to the inner wall surface of the inner case 13, and a groove 17 a on the rear surface of the horizontal moving member 17. The provided contact body 24 that can contact the locking body 23 and the groove 17a on the rear surface of the horizontal moving member 17 provided at a position farther than the operation button 14 than the contact body 24, It is comprised from the protrusion 25 for latching the latching body 23a of the latching body 23. FIG. The arrangement opposite to that of the horizontal positioning mechanism 22 of the present embodiment, that is, a rotatable locking body 23 is provided on the horizontal moving member 17 side, and the contact body 24 and the protrusion 25 are provided on the inner case 13 side. Also good.
[0032]
Further, another groove 17 b is formed on the rear surface of the horizontal moving member 17. Inside the groove 17b, a holding plate 26 protruding from the inner wall surface of the inner case 13 into the inside of the groove 17b and a compression coil spring 27 attached between one end of the groove 17b and the holding plate 26 are housed. Yes. Accordingly, the horizontal moving member 17 is always urged by the compression coil spring 27 in the direction opposite to the pressing direction by the operation button 14 (see arrow P in FIG. 10).
[0033]
As shown in FIGS. 9 to 12, the horizontal positioning mechanism 22 locks the stopper 9 as follows. In the initial state of FIG. 9, the roller 20 on the stopper 9 shown in FIG. 4 is located in the deep portion 21a at the center of the groove 21, so that the stopper 9 is in the lower position, and the claw 9a of the stopper 9 is the inner case. It protrudes downward from the lower surface of 13. However, since the roller 20 is only placed on the horizontal movement member 17, the stopper 9 can move slightly upward alone.
[0034]
From the initial state shown in FIG. 9, first, when the operation button 14 is pushed with a finger, as shown in FIG. 10, the horizontal moving member 17 moves to the left in FIG. Is moved to the right, and the contact body 24 contacts the locking body 23 to rotate the locking body 23.
[0035]
Thereafter, when the finger is released from the operation button 14, the horizontal movement member 17 and the operation button 14 move to the right by the urging force of the compression coil spring 27, as shown in FIG. When the stop portion 23a is locked to the protrusion 25, the stop portion 23a is locked at a position shifted to the left by a predetermined distance from the initial state of FIG. At this time, the roller 20 above the stopper 9 shown in FIG. 4 is located in the shallow portion 21b on the right side of the groove 21, so that the stopper 9 moves upward and the claw 9a of the stopper 9 retracts upward.
[0036]
Furthermore, when the operation button 14 is pushed again with the finger, the contact body 24 further rotates the locking body 23 as shown in FIG. The state can be canceled and the initial state of FIG. 9 can be restored again.
[0037]
Next, an example of a method of using the door stop according to the present embodiment will be described with reference to FIGS. 1 and 4 to 5. First, when the door D is temporarily fixed, the operation button 14 is pushed once with a finger to lock the horizontal moving member 17 at a position shifted to the left as shown in FIG. 11, and the claw 9a of the stopper 9 is retracted upward. After that, when the door D is opened, as shown in FIG. 5, the plate 4 lying on the floor rises by the attractive force of the magnet 2 and is attracted to the lower surface of the magnet 2. At the same time, the lower protrusion 7 provided at the tip of the plate 4 is engaged with the hook 6 of the temporary fixing mechanism 5, whereby 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.
[0038]
When releasing the temporary fixing of the door D, simply closing the door D as it is, the plate 4 easily comes out of the lower surface of the magnet 2 and the temporary fixing of the door D is released.
[0039]
Even if the door D is not temporarily fixed by the temporary fixing mechanism 5, 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. The door D can be temporarily fixed with a holding force that is even weaker than that of the stopping mechanism 5.
[0040]
On the other hand, when the door D is to be locked firmly in the open state, such as when strong winds are blowing, the operation button 14 is pushed once more to return to the initial state of FIG. With the protruding state, the door D is opened to the fully open position.
[0041]
When the door D reaches the fully open position, the plate 4 swings upward and is attracted to the lower surface of the magnet 2, and the stopper 9 engages with the engaging recess 10 of the plate 4 while moving slightly up and down. 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.
[0042]
On the other hand, when it is desired to release the lock of the door D, if the operation button 14 is pushed again with a finger, the stopper 9 moves upward and the lock is released. Therefore, the door D is easily closed after the lock is released. be able to.
[0043]
In the present embodiment, an operation button operated by a finger from the outside has been described as an example of the operation unit. However, the present invention is not limited to this, and the horizontal movement member can be operated horizontally. If so, it is possible to employ an operation unit of another mode. For example, instead of a manual operation button, an electromagnetic solenoid may be adopted as the operation unit and a solenoid operation switch may be provided near the door knob.
[0044]
【The invention's effect】
According to the present invention, the door-side magnet is provided with a temporary fixing mechanism and a locking mechanism, and the magnet, the temporary fixing mechanism, and the locking mechanism are accommodated inside the door without protruding from the surface of the door. be able to. Therefore, the surface of the door becomes flat and the appearance is improved. Moreover, since a magnet etc. do not protrude from the surface of a door, the malfunction that a pedestrian or a load contacts a magnet is also eliminated.
