The locking tool 12 is formed on the back surface of the main body 7 (on the side where the door is attached to the side surface D of the door), and the lower end thereof is vertically and vertically fitted into a recess 15 that is open to the locking recess 10 side. The middle portion thereof is pivotally supported on the main body 7 by the horizontal support shaft 16 so as to be swingable back and forth, and the lower end thereof extends into the locking recess 10 and faces the lower inclined surface 8 of the main body. The stop portion 12a is continuously provided. The spring 13 is, as shown in FIG.
Is urged in the direction in which the hook-shaped locking portion 12a abuts the lower inclined surface 8 of the main body, that is, in the lock position direction, and is locked to the main body 7 above the horizontal support shaft 16 of the locking tool 12. A compression coil spring interposed between the tool 12 and the tool 12 is used.

The lock operation tool 14 has a locking member 17 above the locking tool 12 which is loosely fitted in the main body recess 15 so as to be movable up and down, and a front side of the locking member 17 projects to the front surface of the main body 7. The lifting / lowering operation piece 18 and the click mechanism 19 are provided.

As the horizontal support shaft 16, a spring pin having a C-shaped cross section or the like that can be fixed by simply press-fitting it into the shaft hole can be used.

The mounting position of the floor-side locked body 1 (mounting body 4) with respect to the floor surface 3 is determined so that the operation described below is performed. That is, when the door D moves toward a predetermined position to be positioned (hereinafter referred to as a door locking position), the door side locking means 2 is attached to the side surface Da on the moving direction side, and the floor side locked member 2 is attached. When the door D is at the door locking position, the locking body 1 is arranged directly below the door locking means 2 so that the locked portion 6 faces the door side surface Da side.

When the door D moving toward the door locking position reaches just before the door locking position, the magnet 9 of the door locking means 2 is placed on the tip of the floor locked member 1. As shown by the phantom line in FIG. 1, the floor-side locked body 1 is pulled up by the magnetic attraction force acting between the magnet 9 and the floor-side locked body 1, and the floor-side locked body 1 is pulled up. The stopper 1 swings upward around the horizontal support shaft 5 so that the tip end contacts the inclined lower side surface 8 (lower side surface of the locking recess 10) of the main body 7 of the door side locking means 2. Then, the floor-side locked body 1 and the door-side locking means 2 accompanying the movement of the door D thereafter.
The tip of the floor-side locked body 1 tries to enter into the locking recess 10 of the door-side locking means 2 due to the relative movement with respect to the floor-side locked body 1. The hook-shaped locking portion 12a of the main body inclined lower side surface 8 and the locking tool 12 whose tip is in contact with this.
Since the locking tool 12 swings backward around the horizontal support shaft 16 against the biasing force of the spring 13, the tip of the floor-side locked body 1 is locked. Allow entry into the recess 10.

On the other hand, the lock operation tool 1 of the door lock means 11
As shown in FIGS. 1, 3 and 4, the reference numeral 4 indicates a steel ball 22 of the click mechanism 19 and the upper locking hole 2 in the ascending and retracting position.
The hook-shaped locking portion 12a of the locking tool 12 is held in contact with the upper surface (lower main body inclined surface 8) of the locking recess 10 of the main body 7. In this state, the engaging member is located above the upper end portion 12b of the engaging member 12 above the engaging member 17 of the lock operating tool 14 and directly below the rear portion of the forked portion 17a of the engaging member 17. The upper end portion 12b of the stopper 12 is located, and the lock operation tool 14 (locking member 17) cannot be moved down to the down action position.

As shown in FIG. 4, when the door D reaches the door locking position, the front end of the floor-side locked body 1 abuts on the rear end of the locking recess 10 and the door locking position is reached. Prevent the door D from moving beyond. At this time, the floor-side locked body 1
The tip end locked portion 6 is completely fitted into the locking concave portion 10, the locking tool 12 is returned and rotated by the urging force of the spring 13, and the hook-shaped locking portion 12a is locked on the floor side locked body 1. Since the front end of the floor-side locked body 1 collides with the rear end of the locking recessed portion 10 due to the reaction force or the wind force, the door D is reversed from the door locking position. It is prevented that the hook-shaped locking portion 6 of the locking tool 12 and the locked portion 6 of the floor-side locked body 1 are caught by the hooked locking portion 6 of the locking tool 12. In other words, when the door D moves in the opposite direction from the door locking position, the hook-shaped locking portion 12 of the locking tool 12
The catching between a and the locked portion 6 of the floor-side locked body 1 is a resistance.

Therefore, when the door D locked at the door locking position is moved in the opposite direction, the hook-shaped locking portion 12a of the locking tool 12 and the locked portion of the floor-side locked body 1 are locked. By giving the door D an operating force sufficient to overcome the resistance caused by being caught by the hook 6, the hook-shaped locking portion 12a of the locking tool 12 is locked by the floor-side locked body 1.
It is pushed down by the locked portion 6 of the
The tip portion (locked portion 6) of the floor-side locked body 1 is separated from the inside of the locking recess 10 while being swung rearward against the urging force of the door 3, and the door D is moved in the opposite direction. Will be forgiven. Door D
When 7 moves and the door side locking means 2 separates from the position above the floor-side locked body 1, the floor-side locked body 1 that has been pulled up by the magnetic attraction force pivots downward due to gravity. Then, as shown by the solid line in FIG. 1, it is housed in the mounting body 4.

The locking force of the door D at the door locking position, that is,
Since the resistance force due to the hooking of the hook-shaped locking portion 12a of the locking tool 12 and the locked portion 6 of the floor-side locked body 1 changes depending on the strength of the spring 13, the initial compressive stress of the spring 13 is adjusted. If possible, the door D at the door locking position can be used if necessary.
The locking force of can be adjusted.

When the door D is positioned at the door locking position, that is, when the floor-side locked body 1 is fitted into the locking concave portion 10 of the door-side locking means 2 and is in a butting state, the locking tool 12 is used. As shown in FIG. 4, when the hook-shaped locking portion 12a of the hook and the locked portion 6 of the floor-side locked body 1 are engaged with each other, as shown in FIG.
Is swung backwards against the urging force of the spring 13 and its upper end 12b is located in the middle lower side of the bifurcated portion 17a of the locking member 17 of the lock operation tool 14, so in such a state. Then, the lifting / lowering operation piece 18 of the lock operation tool 14 is lowered from the ascending / retracting position to the descending action position against the resistance of the click mechanism 19, and the forked portion 17a thereof is moved to the upper end 12 of the locking tool 12.
It can be fitted to b. As a result, the locking tool 12 cannot substantially swing rearward, and the locked part 6 of the floor-side locked object 1 pushes the hook-shaped locking part 12a of the locking tool 12 downward to push it away from the door. The locking tool 12 blocks the forward movement of the locking means 2 from the locking recess 10 and the door D is completely locked at the door locking position.

When moving the door D, the click mechanism 1
The lock operation tool 14 of the door lock means 11 held in the lowering action position by 9 is raised from the lowering action position to the upper retracted position against the resistance of the click mechanism 19, and the click mechanism 19 raises the retracted position. By holding the locking member 12 in the state of FIG. 4, the forked portion 17a of the locking member 17 of the lock operation tool 14 is released upward from the upper end portion 12b of the locking tool 12, and the locking tool 12 is free. Therefore, as described above, the door D is moved against the resistance force due to the hooking of the hook-shaped locking portion 12a of the locking tool 12 and the locked portion 6 of the floor-side locked body 1. You can

The lock operating tool 14 for the locking tool 12
Is not limited to the above configuration. The lock operating tool 32 of the door locking means 11 shown in FIGS. 7 and 8 is a locking tool (the locking tool 12 in this embodiment does not have an upper end portion 12b extending above the horizontal support shaft 16). The lateral locking member 33 is supported on the rear surface side of the main body 7 of the door locking means 2 so as to be reciprocally movable within a certain range in the left-right horizontal direction so as to be adjacent to the rear surface of 12. The left and right ends protruding from the main body 7 of the lateral movement locking member 33 have pressing operation portions 34a, 34
b. In addition, as shown in FIG. 7, the lateral movement locking member 33 is moved by pushing one pressing operation portion 34a to a position where it abuts on one side surface of the main body 7 to move the lateral movement locking member 33 to the retracted position. When the switch is switched to, the thin portion 35 adjacent to the back surface of the locking tool 12 and the other pressing operation portion 34b are pressed and moved to a position where they abut on the other side surface of the main body 7 as shown in FIG. A thick portion 36 adjacent to the back surface of the locking tool 12 when the dynamic locking member 33 is switched to the operating position is provided.

Therefore, as shown in FIG. 7, when the thin portion 35 of the lateral movement locking member 33 is located at the retracted position adjacent to the rear surface of the locking tool 12, the lateral movement locking member 33 is located on the floor side. Locking body 1
The locking tool 12 in a state of locking the locked portion 6 of the

When the lateral movement locking member 33 is located at the acting position adjacent to the back surface of the second locking member 2, the locking tool 12 that locks the locked portion 6 of the floor-side locked body 1 resists the spring 13. Then, the floor-side locked body 1
It is configured to prevent the door D positioned at a predetermined position (door locking position) by the floor-side locked body 1 and the door-side locking means 2 from being rocked in a direction away from the door D. ing.

Further, a click mechanism is also provided for the lateral movement locking member 33 of the lock operation tool 32 having the above-mentioned structure so as to hold the lateral movement locking member 33 in the acting position which is laterally moved to one side and the retracted position which is laterally moved to the other side. However, since it is possible to hold the position by friction with the main body 7 or the like, the click mechanism is not necessary. Further, the lateral movement locking member 33 connects the main body 7 to the door side surface Da.
Although it can be held laterally movable at a predetermined position of the main body 7, the lateral movement locking member 33 is provided with a long hole 37 along the lateral movement direction as shown in the drawing.
The lateral movement locking member 33 can be attached to the main body 7 from the back side of the main body 7 with a stopper 38 such as a screw penetrating the main body 7. Further, also in the lock operation tool 32 using the lateral movement locking member 33, as in the previous embodiment, the locking tool 1 is used.
The lock operation tool 32 (the lateral movement locking member 33) holds the locking tool 12 in the locked position only when the locking operation tool 32 (the lateral locking member 33) is engaged with the locked part 6 of the floor-side locked object 1. It is desirable to be able to switch to the working position. The lateral movement locking member 33 can be arranged on the front side above the horizontal support shaft 16 of the locking tool 12.

In the embodiment shown in FIGS. 9 and 10, the locking tool 12 of the door locking means 11 uses a spring (a torsion coil spring is used, but a tension coil spring, a leaf spring or the like may be used) 39. Energized in the unlocking direction. Therefore, the lock operation tool 40 of the door lock means 11
Similarly to the lock operation tool 14 described above, the locking member 17 attached to the main body 7 and the lifting operation piece 18, and the click mechanism 19 for positioning the locking member 17 at the ascending / retracting position and the descending action position. However, instead of the forked portion 17a, the lower end of the locking member 17 acts on the upper end portion 12b of the locking tool 12 in the unlocked position when descending from the ascending / retracting position to the descending action position. A cam portion 41 for forcibly swinging the locking tool 12 to the lock position is provided so as to project.

As described above, when the locking tool 12 is urged in the unlocking direction by the spring 39, the door D is moved beyond the door locking position by locking the door side locking means 2. Recess 1
Although it is possible to position the door D at the door locking position in a state in which the front end of the floor-side locked body 1 with respect to 0 is blocked by the engagement, the door D moves in the opposite direction from the door locking position. There is little resistance to doing. However, it is necessary to completely lock the door D, which is positioned by the abutment of the tip of the floor-side engaged body 1 with the engaging recess 10 of the door-side engaging means 2, at the door engaging position. At this time, the lock operation tool 40 (the lifting operation piece 18) in the ascending / retracting position is lowered to the lowering action position against the resistance of the click mechanism 19 so that the lower end cam portion 41 of the locking member 17 locks it. The upper end portion 12b of the tool 12 is pressed and moved rearward, so that the locking tool 12 is placed between the hook-shaped locking portion 12a and the upper surface of the locking recess 10 (the lower inclined surface 8 of the main body) on the floor side. The locked portion 6 of the locked body 1 can be switched to the lock position where it is clamped and held, and the door D can be completely prevented from moving in the opposite direction from the door locking position. When it is desired to move the door D, the lock operation tool 40 (the lifting operation piece 18) in the lowering operation position is moved up against the resistance of the click mechanism 19 to the up and down position, and the lower end cam portion of the locking member 17 thereof. 41 is the upper end 12 of the locking tool 12
It suffices to disengage the lock 12 from b and return the locking tool 12 to the unlocked position by the biasing force of the spring 39.

The door positioning device composed of and is used as a door stop for positioning the door D at the rotation limit position. However, the door positioning device of the present invention can also be used as a door positioning device that prevents a hanging type folding door or sliding door whose lower portion is not guided by a guide rail from swinging inward and outward at the closed limit position. In this case, since the moving direction of the folding door or the sliding door near the closing limit position is substantially parallel to the door side surface Da, the tip end of the floor-side locked body 1 engages with the door-side locking means 2. It will enter relative to the stop recess 10 from the lateral direction.

Further, in the door positioning device of the present invention, the door side locking means 2 can be embedded in the lower end of the door D. In this case, the main body 7 may be used also as a door constituent member, or the main body 7 as a separate member may be embedded in the lower end of the door D.

The door positioning device of the present invention can be implemented and used as described above, and according to the door positioning device of the present invention, a door moved to a predetermined position can be magnetically moved. The floor-side locked body, which is obliquely erected by the suction force, is fitted and abutted against the locking recess of the door-side locking means to stop the door, and reliably prevent the door from moving beyond that position. However, if you want to completely lock (lock) the door at that position, you can simply switch the locking device of the door lock means in the unlocked state to the locked state, and simply touch the door at the specified position. It is possible to use the function of just stopping and the function of completely fixing (locking) the door at a predetermined position.

According to the second aspect of the present invention, the door locking means includes the floor-side locked body for locking the door at a predetermined position and the locking tool provided on the door-side locking means. The structure on the floor side is simpler and easier to carry out, as compared with the case where parts or portions dedicated to the door locking means must be provided separately from the locked body on the floor side. Become. In this case, according to the configuration of claim 3, the locked portion required at the tip of the floor-side locked body can be easily configured,
Moreover, at the same time, since the tip end portion of the locked body can also be reinforced, the locked body can be inexpensively constructed from a metal plate having a relatively thin plate thickness.

Further, according to the structure of claim 4, even if the door is not completely fixed at the predetermined position by the door locking means, the door locked in the predetermined position will not be returned by an external force below a certain level. The door can be held automatically, and the door will not easily move or sway due to wind, etc., and a reliable contact-stopping effect can be obtained. In addition, it is possible to completely fix the door in the stopped state, if necessary, which improves usability. In this case, according to the configuration of claim 5, since the locking tool of the door locking means is erroneously switched to the lock position before the door is stopped, the door is moved to the predetermined position and contacted. The inconvenience of being unable to stop is eliminated.

Further, the structure described in claim 6 is suitable when it is not necessary to elastically hold the door at the position where it is stopped, and when it is desired to completely fix the door at the position where it is stopped. Since only the locking tool is switched to the lock position, the floor-side locked body is locked to lock the door, but the locking tool and the floor-side locked body are normally engaged. It is possible to avoid the generation of noise and wear due to exercise.

According to the seventh aspect of the present invention, the locking tool of the door locking means can be switched between the locked state and the unlocked state by the lock operation tool, but the lock operation tool moves up and down. Since it is a moving object and the door is locked by pushing it down, it has good operability and can be operated without error. Further, according to the configuration of claim 8, since the lock operation tool reciprocates in the horizontal direction in the left-right direction, there is no need for a click mechanism or the like for holding the lock operation tool at the working position or the retracted position. It is unlikely that the lock operation tool will unexpectedly move and the locked state will be released, and a reliable operation can be expected while simplifying the configuration.

According to the ninth aspect of the present invention, the door can be locked easily with the same feeling as in the conventional door contact using the hook, and the configuration is simple and can be implemented at low cost.
