Japanese Utility Model Publication No. 62-164866 (Fig. 2)

By the way, in the door device as described above, it is preferable to provide a guide mechanism for guiding the door group so that the door group moves appropriately. However, the provision of the guide mechanism is disadvantageous in that it causes an increase in the size of the door device and an increase in the manufacturing cost.

Therefore, it is desired to realize a door device that can reduce the size and manufacturing cost even if it has a configuration including a guide mechanism for guiding the door group.

In view of the above, the characteristic configuration of the door device is
A gate group of M group (M is 1 or 2);
a guide mechanism for guiding the M group of door bodies,
Each of the M groups of door bodies includes N doors (N is a natural number of 2 or more) that move in the opening/closing direction, and is configured to change between a closed state and an open state,
The position in the opening/closing direction of each of the N door bodies in the closed state is defined as a closed position, the position in the opening/closing direction of each of the N door bodies in the open state is defined as an open position, and the closed position is defined as The side from the open position to the open position is the open side, the side from the open position to the closed position is the closed side, the direction orthogonal to the N doors is the front-rear direction, and the front-rear direction along the front-rear direction. The direction perpendicular to the opening and closing direction when viewed is defined as the opening and closing width direction, one side in the opening and closing width direction is defined as the first side in the width direction, and the opposite side of the first side in the width direction is defined as the second side in the width direction,
The N door bodies are arranged so as to line up in the opening and closing direction in the closed state, and are arranged so as to overlap each other in the front-rear direction view in the open state,
The guide mechanism is
N first guide rails arranged on the first side in the width direction with respect to the M group of door bodies and extending along the opening and closing direction;
one second guide rail arranged on the second side in the width direction with respect to the group of M doors and extending along the opening/closing direction;
a first connector that is connected to each of the N×M doors and that slides along the corresponding first guide rail;
a second connector that is connected to each of the N×M doors and slides along the second guide rail;
Each of the N first couplers corresponding to each of the M group of door bodies is arranged on both sides in the opening/closing direction with respect to the center of gravity of the door body corresponding to the first coupler. ,
The N second connectors corresponding to each of the M groups of door bodies do not overlap each other in the open state when viewed in the front-rear direction, and the corresponding door bodies in the closed position and the open position do not overlap each other in the open state. arranged to be positioned on the open side as the distance from the position increases ,
further comprising a power transmission mechanism disposed on at least one of the first side in the width direction and the second side in the width direction with respect to the group of M doors, and transmitting power to the group of M groups of doors;
The power transmission mechanism is
N pulley pairs composed of N first pulleys arranged coaxially and rotating together and N second pulleys arranged coaxially and rotating together;
N belts each wound around N pairs of said pulleys;
a belt connector that connects each of the N belts and the door body corresponding to the belt,
the outer diameters of the first pulley and the second pulley constituting one pulley pair are the same;
The outer diameter of each of the N first pulleys is set according to the distance between the closed position and the open position of the door body corresponding to the first pulley,
The power transmission mechanism is arranged on the first side in the width direction with respect to the door group of the M group,
The first connecting member and the belt connecting member connected to the same door body overlap each other in the opening/closing direction .

According to this characteristic configuration, the guide mechanism includes N first guide rails arranged on the first side in the width direction with respect to the M group of door bodies, and N first guide rails arranged on the first side in the width direction of the M group of door bodies. and one second guide rail arranged on two sides. That is, on the first side in the width direction with respect to the M group of door bodies, one guide rail is arranged for each of the N gate bodies, for a total of N first guide rails. On the second side in the width direction, one second guide rail is arranged for the N×M door bodies. In this way, one of the two types of guide rails provided in the guide mechanism (the second guide rail) is a guide rail common to the N×M doors, thereby reducing the number of guide rails. can be done. Therefore, the size and manufacturing cost of the door device can be kept small.
In addition, in the N×M second couplers sliding along the second guide rail, the N second couplers corresponding to each door group do not overlap each other when viewed in the front-rear direction in the open state. In addition, as the distance between the closed position and the open position of the corresponding door body increases, it is positioned on the open side. Therefore, when the N second couplers corresponding to each door group slide along the second guide rail, it is possible to prevent the second couplers from interfering with each other. Therefore, even if only one second guide rail is provided for the N×M doors, the N×M doors can be moved appropriately in the opening/closing direction.
Further, as described above, the N second connectors corresponding to each door group are arranged so as to be positioned on the opening side as the distance between the closed position and the open position of the corresponding door increases. there is Therefore, each of the N second connectors corresponding to each door group may be connected to a position away from the center of gravity of the door body corresponding to the second connector in the opening/closing direction. It is difficult to support the gate body in a balanced state by the tool alone. However, on the side opposite to the second connector side (the first side in the width direction) with respect to the M group of door bodies, each of the N×M first connectors corresponds to the first connector. It is arranged over both sides in the opening and closing direction with respect to the center of gravity of the door body. Therefore, the door can be supported in a balanced state from the first side in the width direction by the first connector.
Further, according to the above characteristic configuration, by rotating either one of the first pulley and the second pulley, the N×M doors are opened and closed via the N belts. can be moved in any direction.
Further, the outer diameters of the first pulley and the second pulley that constitute one pulley pair are the same, and the outer diameter of each of the N first pulleys is the same as that of the door body corresponding to the first pulley. It is set according to the distance between the position and the open position. Therefore, even if each of the N first pulleys and the N second pulleys is arranged coaxially and rotates integrally, the distance between the closed position and the open position differs in each door group. Each of the N doors can be appropriately moved between the closed position and the open position.
Moreover, according to the above characteristic configuration, the first connector and the belt connector connected to the same door can be arranged close to each other in the opening/closing direction. As a result, it becomes easy to keep the arrangement area in the opening/closing direction small for the first coupler and the belt coupler.

a guide mechanism for guiding the M group of door bodies,
Each of the M groups of door bodies includes N doors (N is a natural number of 2 or more) that move in the opening/closing direction, and is configured to change between a closed state and an open state,
The position in the opening/closing direction of each of the N door bodies in the closed state is defined as a closed position, the position in the opening/closing direction of each of the N door bodies in the open state is defined as an open position, and the closed position is defined as The side from the open position to the open position is the open side, the side from the open position to the closed position is the closed side, the direction orthogonal to the N doors is the front-rear direction, and the front-rear direction along the front-rear direction. The direction perpendicular to the opening and closing direction when viewed is defined as the opening and closing width direction, one side in the opening and closing width direction is defined as the first side in the width direction, and the opposite side of the first side in the width direction is defined as the second side in the width direction,
The N door bodies are arranged so as to line up in the opening and closing direction in the closed state, and are arranged so as to overlap each other in the front-rear direction view in the open state,
The guide mechanism is
N first guide rails arranged on the first side in the width direction with respect to the M group of door bodies and extending along the opening and closing direction;
one second guide rail arranged on the second side in the width direction with respect to the group of M doors and extending along the opening/closing direction;
a first connector that is connected to each of the N×M doors and that slides along the corresponding first guide rail;
a second connector that is connected to each of the N×M doors and slides along the second guide rail;
Each of the N first couplers corresponding to each of the M group of door bodies is arranged on both sides in the opening/closing direction with respect to the center of gravity of the door body corresponding to the first coupler. ,
The N second connectors corresponding to each of the M groups of door bodies do not overlap each other in the open state when viewed in the front-rear direction, and the corresponding door bodies in the closed position and the open position do not overlap each other in the open state. It is arranged to be positioned on the open side as the distance from the position increases.

According to this configuration, the guide mechanism includes the N first guide rails arranged on the first side in the width direction with respect to the M group of door bodies, and the second guide rail in the width direction with respect to the M group of door bodies. and a second guide rail arranged on the side. That is, on the first side in the width direction with respect to the M group of door bodies, one guide rail is arranged for each of the N gate bodies, for a total of N first guide rails. On the second side in the width direction, one second guide rail is arranged for the N×M door bodies. In this way, one of the two types of guide rails provided in the guide mechanism (the second guide rail) is a guide rail common to the N×M doors, thereby reducing the number of guide rails. can be done. Therefore, the size and manufacturing cost of the door device can be kept small.
In addition, in the N×M second couplers sliding along the second guide rail, the N second couplers corresponding to each door group do not overlap each other when viewed in the front-rear direction in the open state. In addition, as the distance between the closed position and the open position of the corresponding door body increases, it is positioned on the open side. Therefore, when the N second couplers corresponding to each door group slide along the second guide rail, it is possible to prevent the second couplers from interfering with each other. Therefore, even if only one second guide rail is provided for the N×M doors, the N×M doors can be moved appropriately in the opening/closing direction.
Further, as described above, the N second connectors corresponding to each door group are arranged so as to be positioned on the opening side as the distance between the closed position and the open position of the corresponding door increases. there is Therefore, each of the N second connectors corresponding to each door group may be connected to a position away from the center of gravity of the door body corresponding to the second connector in the opening/closing direction. It is difficult to support the gate body in a balanced state by the tool alone. However, on the side opposite to the second connector side (the first side in the width direction) with respect to the M group of door bodies, each of the N×M first connectors corresponds to the first connector. It is arranged over both sides in the opening and closing direction with respect to the center of gravity of the door body.

Further, the outer diameters of the first pulley and the second pulley that constitute one pulley pair are the same, and the outer diameter of each of the N first pulleys is the same as that of the door body corresponding to the first pulley. It is set according to the distance between the position and the open position. Therefore, even if each of the N first pulleys and the N second pulleys is arranged coaxially and rotates integrally, the distance between the closed position and the open position differs in each door group. Each of the N doors can be appropriately moved between the closed position and the open position.

In a configuration including the power transmission mechanism,
The power transmission mechanism is arranged on the first side in the width direction with respect to the door group of the M group,

As a result, when the N doors in each door group move in the opening/closing direction, the second connector and the belt connector connected to the same door are replaced by the second connector connected to another door. It is possible to make it difficult to interfere with the tool and the belt connector.

Further, the power transmission mechanism is arranged on the second side in the width direction with respect to the door group of the M group,
It is preferable that the second guide rail is arranged on one side in the front-rear direction with respect to the N pulley pairs.

According to this configuration, it becomes easy to dispose the second guide rail and the N pulley pairs close to each other in the opening/closing width direction. Therefore, the dimension of the door device in the opening/closing width direction can be kept small.

Further, it is preferable that the belt and the door body, which are connected to each other by the belt connector, are arranged so as to overlap each other when viewed in the opening/closing width direction along the opening/closing width direction.

According to this configuration, the belt and the door connected to each other by the belt connector can be arranged close to each other in the front-rear direction. Therefore, the dimension of the door device in the front-rear direction can be kept small.
