BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a door body moving device of the present invention will be described below with reference to the drawings.

1 to 6 show a first embodiment of the door body moving device of the present invention.
This door body moving device, like the door body moving device disclosed in Patent Document 1, is provided on either one side of the door frame F or the door body D (in this embodiment, on the door frame F side). An apparatus main body 1 having an arm 11 that rotates under force, and an arm 11 provided on the other side of either the door frame F or the door body D (in this embodiment, the door body D side). It consists of a guide member 2 having a first opening 21 through which the distal end portion 12 is introduced and withdrawn, and a first guide groove 22 for guiding the distal end portion 12 of the arm 11 connected to the first opening 21 .
When the door body D is in the half-open state, the distal end portion 12 of the protruding arm 11 is introduced into the first guide groove 22 from the first opening 21 of the guide member 2 and enters the first guide groove 22. The door body D is moved from the half-open state to the closed state by being guided along.

The device main body 1 of the door moving device has the same basic structure as the device main body 1 of the door moving device disclosed in Patent Document 1. As shown in FIG.
Specifically, the apparatus main body 1 has an arm 11 , a roller forming a distal end portion 12 of the arm 11 , a link member 13 , an urging means 14 and a damper 15 .
Further, the guide member 2 of the door moving device has the same basic structure as the guide member of the door moving device disclosed in Patent Document 1. As shown in FIG.
Specifically, the guide member 2 guides the first opening 21 through which the distal end portion 12 of the arm 11 is introduced and withdrawn, and the distal end portion 12 of the arm 11 connected to the first opening 21 through the guide portion 21a. It has a body portion 20 and a cover 27 provided with a first guide groove 22 for guiding.

As a result, as shown in FIGS. 1, 4(a1) to 4(a2), and 5, when the door body D is changed from the fully open state to the closed state, when the door body D is in the half-open state, the projecting state is introduced into the first guide groove 22 from the first opening 21 of the guide member 2 via the guide portion 21a and guided along the first guide groove 22. However, at this time, the biasing force of the biasing means 14 in the direction of closing the door D and the deceleration force of the damper 15 automatically move the door D from the half-open state to the closed state.

On the other hand, when the door D is fully opened from the closed state, the front end portion 12 of the arm 11 moves toward the guide member 2 against the biasing force of the biasing means 14 in the closing direction of the door D and the deceleration force of the damper 15 . However, when the door body D is in a half-open state, the distal end portion 12 of the arm 11 moves from within the first guide groove 22 to the first guide groove 22 of the guide member 2. The arm 11 protrudes through the opening 21 . After that, the door body D can be moved from the half-open state to the fully open state.

Here, as a means for maintaining the arm 11 in the projecting state, by locking the base end portion of the arm 11, an arm position consisting of a plate spring that prevents the arm 11 from swinging due to the biasing force of the biasing means 14 is provided. A holding means 16 is provided.

Further, as shown in FIGS. 2, 3, 4(b1) to 4(b2) and FIG. 6, the guide member 2 of the door moving device is provided with a guide member similar to the guide member of the door moving device disclosed in Patent Document 1. In addition to the basic structure of 1, when the door body D is moved from the half-open state to the closed state, it is in the stored state without being guided along the first guide groove 22, that is, in the malfunction state. A second opening 23 into which the distal end portion 12 of the arm 11 is introduced and one end of which is connected to the second opening 23 and the other end of which is connected to the first opening 21 are provided as auxiliary means for restoring the broken arm 11 to a normal operation state. A second guide groove 24 is provided for guiding the distal end portion 12 of the continuous arm 11, and when the door body D is moved from the closed state to the half-open state, the distal end portion 12 of the arm 11 is guided by the second guide groove. 24 and led out from the first opening 21, the arm 11 is in a projecting state.

As a result, the distal end portion 12 of the arm 11, which is in the retracted state without being guided along the first guide groove 22, that is, is in the malfunction state, is moved until the door body D is closed. When the door body D is moved from the closed state to the half-open state after that, the arm 11 in the malfunctioning state is introduced into the second guide groove 24 through the second opening 23. The distal end portion 12 is guided along the second guide groove 24 and led out from the first opening 21 so that the arm 11 is in a projecting state, thereby preventing the arm 11 from malfunctioning. By automatically returning to the projecting state from the housed state along the apparatus main body 1, normal operation can be performed when the door body D is next closed.

Here, the guide member 2 of the door moving device is provided with a spring member 25 for receiving the tip portion 12 of the arm 11 at the end portion of the first guide groove 22 .
As a result, impact and noise generated when the door body D is closed can be reduced.

Further, the second opening 23 is provided with a restricting means 26 for preventing the distal end portion 12 of the arm 11 introduced from the second opening 23 into the second guide groove 24 from being led out from the second opening 23. I'm trying
The restricting means 26 includes a movable body 26a forming an operated piece 26b against which the distal end portion 12 of the arm 11 abuts, which closes the second opening 23, and the movable body 26a is attached in a direction to close the second opening 23. It consists of a spring member 26c for biasing and a slide cover 26d for guiding the moving body 26a.
As a result, when the distal end portion 12 of the arm 11 in the malfunctioning state is moved until the door body D is closed, the distal end portion 12 of the arm 11 contacts the operated piece 26b, thereby moving the moving body 26a. is moved against the biasing force of the spring member 26c and introduced into the second guide groove 24 through the second opening 23, and then by the moving body 26a returned by the biasing force of the spring member 26c. Closing the second opening 23 prevents the distal end portion 12 of the arm 11 from being pulled out from the second opening 23 .

7 to 11 show a second embodiment of the door body moving device of the present invention.
In this door body moving device, when the door body D is moved by the guide member 2 from the half-open state to the closed state, the door body D is not guided along the first guide groove 22 and enters the retracted state. That is, as an auxiliary means for restoring the malfunctioning arm 11 to a normal state, the door body D is guided along the first guide groove 22 when moved from the half-open state to the closed state. A second opening 23 connected to a first guide groove 22 into which the distal end portion 12 of the arm 11 in the stored state is introduced. The second opening 23 is provided with an inclined surface 28a. and a first auxiliary member 28 which is pushed down against the biasing force of the spring 28b by contacting the tip portion 12 of the arm 11, and the first auxiliary member 28 interlocks against the biasing force of the spring 29b. and a second auxiliary member 29 constituting a part of the side wall of the first guide groove 22, which is pushed down by the arm 11 when the door body D is moved from the closed state to the half-open state. The portion 12 is guided along the first guide groove 22 and led out from the first opening 21 so that the arm 11 is in a projecting state.

Here, the first auxiliary member 28 has a projection 28c formed on the rear surface thereof, and the projection 28c is fitted into a guide groove 29c formed on the front surface of the second auxiliary member 29, whereby the second auxiliary member 29 is interlocked with the first auxiliary member 28 .
The upper edge of the inclined surface 28a of the first auxiliary member 28 is always higher than the flat upper surface 29a of the second auxiliary member 29, so that the distal end portion 12 of the arm 11 is positioned at the first position. A smooth transition from the inclined surface 28a of the second auxiliary member 28 to the upper surface 29a of the second auxiliary member 29 is possible.

In this door body moving device, similarly to the door body moving device of the first embodiment, when the door body D is moved from the fully open state to the closed state, when the door body D is in the half open state, the protruding arm 11 is The tip portion 12 is introduced into the first guide groove 22 from the first opening 21 of the guide member 2 and is guided along the first guide groove 22 until the door body D is moved from the half-open state to the closed state. I am trying to move it automatically.
At this time, the first auxiliary member 28 and the second auxiliary member 29 are in a raised position due to the biasing force of the springs 28b, 29b, and the rear surface 29d of the second auxiliary member 29 is aligned with the first guide groove 22. , to guide the distal end portion 12 of the protruding arm 11. As shown in FIG.

On the other hand, when the door D is fully opened from the closed state, the distal end portion 12 of the arm 11 is guided along the first guide groove 22 of the guide member 2, and when the door D is in the half-open state, The distal end portion 12 of the arm 11 is pulled out from the first guide groove 22 through the first opening 21 of the guide member 2, and the arm 11 is brought into a projecting state. After that, the door body D can be moved from the half-open state to the fully open state.

On the other hand, when the distal end portion 12 of the arm 11 is not guided along the first guide groove 22 and is in a stored state, that is, when a malfunction occurs, the distal end portion 12 of the arm 11 is , the door D is introduced into the first guide groove 22 via the second opening 23, the first auxiliary member 28 and the second auxiliary member 29 when the door D is moved to the closed state. Then, when the door body D is moved from the closed state to the half-open state, the distal end portion 12 of the malfunctioning arm 11 is guided along the first guide groove 22 to open the first opening 21. By pulling out the arm 11 from the main body 1, the arm 11 in the malfunctioning state is automatically returned to the protruded state from the stored state along the apparatus main body 1, so that the arm 11 is in the protruded state. In addition, normal operation can be performed when the door body D is closed.

In this case, normally, as shown in FIGS. 9A and 9B, when the door body D is moved to the closed state, the tip of the arm 11 is placed on the inclined surface 28a of the first auxiliary member 28. When the portion 12 abuts, the first auxiliary member 28 is pushed down against the biasing force of the spring 28b, and in conjunction with this, the second auxiliary member 29 is pushed down against the biasing force of the spring 29b. As a result, the distal end portion 12 of the arm 11 is introduced into the first guide groove 22, and the first auxiliary member 28 and the second auxiliary member 29 are returned to their raised positions by the biasing forces of the springs 28b and 29b. I am trying to

On the other hand, if the tip portion 12 of the arm 11 is not normally introduced into the first guide groove 22 due to an installation error of the guide member 2 or the like, the door body D is closed as shown in FIG. 9(c). , the distal end portion 12 of the arm 11 comes into contact with the inclined surface 28a of the first auxiliary member 28, thereby pushing down the first auxiliary member 28 against the biasing force of the spring 28b. , the second auxiliary member 29 is pushed down against the biasing force of the spring 29b, so that the distal end portion 12 of the arm 11 moves to the position of the second auxiliary member 29, and the first auxiliary member 28 alone returns to the raised position by the biasing force of the spring 28b, so that the distal end portion 12 of the arm 11 is introduced into the first guide groove 22 while the second auxiliary member 29 remains pushed down. I'm trying to be
In this case also, when the door body D is moved from the closed state to the half-open state after that, the distal end portion 12 of the malfunctioning arm 11 is guided along the first guide groove 22 to the first position. By causing the arm 11 to protrude from the opening 21, the arm 11 in the malfunctioning state is automatically returned from the stored state along the device main body 1 to the protruded state, By returning the second auxiliary member 29 to the raised position by the biasing force of the spring 29b, the door body D can be operated normally when the door body D is closed next time.

Other configurations and functions of this embodiment are the same as those of the door body moving device of the first embodiment.

Although the door body moving device of the present invention has been described above based on the embodiments thereof, the present invention is not limited to the configurations described in the above embodiments, and can be modified as appropriate without departing from the scope of the invention. It is configurable.
