Description
Technical Field
The present invention relates to a door device including a door body group including a plurality of door bodies.
Background
An example of such a door device is disclosed in jp 62-164866 a. In the following description of the background art, reference numerals in JP-B-62-164866 are given in parentheses.
In the door device disclosed in jp 62-164866 a, a plurality of door bodies (40) are connected to a belt (30) wound around a pair of pulleys (23). When the plurality of belts (30) are rotationally driven via the plurality of pairs of pulleys (23) by the drive device (21), the plurality of door bodies (40) move in a closed state or an open state according to the rotational direction of the plurality of belts (30).
However, in the door device as described above, it is preferable to provide a guide mechanism for guiding the door body group so that the door body group moves appropriately. However, the provision of the guide mechanism is disadvantageous in that it increases the size of the door device and increases the manufacturing cost.
Disclosure of Invention
Therefore, even in a structure including a guide mechanism for guiding the door body group, it is desirable to realize a door device capable of suppressing the size and manufacturing cost.
In view of the above, the door device is characterized by comprising M groups (M is 1 or 2) of door bodies and a guide mechanism for guiding the M groups of door bodies, wherein the M groups of door bodies are formed so as to include N (N is a natural number of 2 or more) door bodies that move in an opening/closing direction, and can be changed between a closed state and an open state, a position in the opening/closing direction in the closed state of each of the N door bodies is defined as a closed position, a position in the opening/closing direction in the open state of each of the N door bodies is defined as an open position, a side from the closed position toward the open position is defined as an open side, a side from the open position toward the closed position is defined as a closed side, a direction orthogonal to the N door bodies is defined as a front-rear direction, and a direction orthogonal to the opening/closing direction when viewed in the front-rear direction is defined as an opening/closing width direction, wherein one side in the opening/closing width direction is a width direction 1 st side, an opposite side to the width direction 1 st side is a width direction 2 nd side, N door bodies are arranged in line in the opening/closing direction in the closed state and are arranged so as to overlap with each other when viewed in the front-rear direction in the open state, the guide mechanism includes N1 st guide rails, 1 nd 2 nd guide rails, 1 st couplers, and 2 nd couplers, the N1 st guide rails are arranged on the width direction 1 st side with respect to M door body groups and extend in the opening/closing direction, the 1 nd 2 nd guide rails are arranged on the width direction 2 nd side with respect to M door body groups and extend in the opening/closing direction, the 1 st couplers are coupled to each of N × M door bodies and slide along the corresponding 1 st guide rails, the 2 nd coupler is coupled to each of the N × M door bodies and slides along the 2 nd guide rail, each of the N1 st couplers corresponding to each of the M door body groups is disposed on both sides in the opening/closing direction with respect to a center of gravity of the door body corresponding to the 1 st coupler, and the N2 nd couplers corresponding to each of the M door body groups are disposed so as not to overlap each other when viewed in the front-rear direction in the open state and are positioned on the opening side as a distance between the closed position and the open position of the corresponding door body becomes longer.
According to this characteristic structure, the guide mechanism includes N1 st guide rails disposed on the 1 st side in the width direction with respect to the M-group door body group, and 12 nd guide rails disposed on the 2 nd side in the width direction with respect to the M-group door body group. That is, the 1 st guide rails are arranged 1 for each of the N doors on the 1 st side in the width direction with respect to the M-group door group, and the 1 nd guide rails are arranged 1 for the N × M doors on the 2 nd side in the width direction with respect to the M-group door group. In this way, by setting one of the two types of guide rails (the 2 nd guide rail) provided in the guide mechanism to a guide rail common to the N × M door bodies, the number of guide rails can be reduced. Therefore, the size and manufacturing cost of the door device can be suppressed to be small.
The N × M2 nd couplers sliding along the 2 nd guide rail are arranged so that the N2 nd couplers corresponding to the respective door body groups do not overlap with each other when viewed in the front-rear direction in the open state, and are positioned on the open side as the distance between the closed position and the open position of the corresponding door body becomes longer. Therefore, when the N2 nd couplers corresponding to the respective door body groups slide along the 2 nd guide rail, the 2 nd couplers can be prevented from interfering with each other. Therefore, even in the configuration in which the number of the 2 nd guide rails is 1 for the N × M doors, the N × M doors can appropriately move in the opening and closing direction.
As described above, the N2 nd couplers corresponding to the respective door groups are arranged so as to be positioned on the opening side as the distance between the closing position and the opening position of the corresponding door becomes longer. Therefore, each of the N2 nd couplers corresponding to each door body group may be coupled to a position of the door body corresponding to the 2 nd coupler, which is apart from the center of gravity in the opening and closing direction, and it may be difficult to support the door body in a balanced state by the 2 nd coupler alone. However, on the opposite side (the 1 st side in the width direction) from the 2 nd coupler side with respect to the M-group door body group, each of the N × M1 st couplers is disposed across both sides in the opening and closing direction with respect to the center of gravity of the door body corresponding to the 1 st coupler. Therefore, the door body can be supported in a balanced state from the 1 st side in the width direction by the 1 st coupler.

Detailed Description
1. Embodiment 1
Hereinafter, the gate device 100 according to embodiment 1 will be described with reference to the drawings. Fig. 1 and 2 show a front view, a top view, and a bottom view of the gate device 100, respectively. Specifically, in fig. 1 and 2, a front view of the gate device 100 is shown in the center, a top view of the gate device 100 is shown in the upper part, and a bottom view of the gate device 100 is shown in the lower part, respectively.
As shown in fig. 1 and 2, the door device 100 includes M door body groups 10(M is 1 or 2), and a guide mechanism 20 that guides the M door body groups 10. In the present embodiment, the door device 100 includes two door groups 10(M is 2). The two door body groups 10 are formed to be line-symmetrical with respect to a center line C which is an imaginary line parallel to the vertical direction. Therefore, only the door group 10 disposed on one side with respect to the center line C (left side door group 10 in fig. 1 and 2) of the two door groups 10 will be described below, except for the case where it is specifically explicitly described.
The door group 10 is configured to be capable of being changed into a closed state and an open state. The door group 10 includes N (N is a natural number of 2 or more) door bodies 1 that move in the opening and closing direction S. In the present embodiment, the door group 10 includes two doors 1(N — 2). In the present embodiment, the opening/closing direction S is a direction along the horizontal direction.
In the following description, one of the two door bodies 1 that is close to the center line C is referred to as an "inner door body 1A", and the other that is away from the center line C is referred to as an "outer door body 1B". The positions in the opening and closing direction S in the closed state of the inner door 1A and the outer door 1B are referred to as an "inner closing position P1A" and an "outer closing position P1B", respectively. On the other hand, the positions in the opening and closing direction S in the opened state of the inner door body 1A and the outer door body 1B are referred to as an "inner opening position P2A" and an "outer opening position P2B", respectively. In the opening/closing direction S, the side from the inner closing position P1A toward the inner opening position P2A (the side from the outer closing position P1B toward the outer opening position P2B) is referred to as "opening side S1", and the opposite side is referred to as "closing side S2".
A direction orthogonal to the door body 1 (specifically, a direction orthogonal to the surface of the door body 1) is referred to as a "front-rear direction D". One side in the front-rear direction D is referred to as "front side D1", and the other side is referred to as "rear side D2". In addition, when viewed in the front-rear direction of the front-rear direction D, a direction orthogonal to the opening-closing direction S is referred to as an "opening-closing width direction W". One side in the opening/closing width direction W is referred to as "width direction 1 st side W1", and the other side is referred to as "width direction 2 nd side W2". In the present embodiment, the opening/closing width direction W is a direction along the vertical direction.
The inner door 1A and the outer door 1B are arranged in the opening/closing direction S in the closed state (see fig. 1). The inner door body 1A and the outer door body 1B are arranged so as to overlap each other when viewed in the front-rear direction along the front-rear direction D in the opened state (see fig. 2). In the present embodiment, the inner door body 1A is disposed on the rear side D with respect to the outer door body 1B. Here, regarding the arrangement of the two elements, "overlap when viewed in a specific direction" means that when a virtual straight line parallel to the visual line direction is moved in each direction orthogonal to the virtual straight line, most of each element exists in a region where the virtual straight line intersects both of the two elements. Here, "most" means more than half of the area occupied by each element when viewed in a specific direction.
In the present embodiment, two door pockets ( pockets) 11 are provided, which correspond to the two door groups 10, respectively. Each door pocket 11 is formed to close an opening formed on the open side S1 with respect to the outer door body 1B in the closed state (see fig. 1). Each of the door pockets 11 is formed to overlap both the inner door body 1A and the outer door body 1B when viewed in the front-rear direction of the front-rear direction D in the opened state (see fig. 2).
The guide mechanism 20 includes N1 st guide rails 2, 1 nd 2 guide rails 3, N × M1 st couplers 4, and N × M2 nd couplers 5. In the present embodiment, the guide mechanism 20 includes two 1 st guide rails 2, 1 nd 2 guide rails 3, 4 st couplers 4, and 4 nd couplers 5(N ═ 2, and M ═ 2).
The N1 st guide rails 2 are formed to extend in the opening and closing direction S. The N1 st guide rails 2 are disposed on the 1 st widthwise side W1 with respect to the M groups of door bodies 10. In the present embodiment, the two 1 st guide rails 2 are arranged in the front-rear direction D.
In the following description, the 1 st guide rail 2 disposed on the front side D1 of the two 1 st guide rails 2 is referred to as a "front guide rail 2F", and the 1 st guide rail 2 disposed on the rear side D2 is referred to as a "rear guide rail 2R".
Each of the N × M1 st couplers 4 is coupled to a corresponding one 1 of the N × M door bodies 1. That is, 1 st coupler 4 is coupled to 1 door body 1. In the present embodiment, 1 st coupler 4 is coupled to the inner door 1A of each door group 10, and 1 st coupler 4 is coupled to the outer door 1B of each door group 10.
In the present embodiment, each 1 st coupler 4 includes two 1 st coupling members 41. The two 1 st coupling members 41 are disposed on both sides in the opening/closing direction S with respect to the center of gravity G of the door body 1. Here, the center of gravity G of the door body 1 coincides with the center of mass of the door body 1. In the present embodiment, the center of gravity G of the door 1 is located at the center of the door 1 in the opening/closing direction S and at the center of the opening/closing width direction W. The two 1 st coupling members 41 are disposed on both sides of the center of gravity G in the opening/closing direction S so as to be the same distance from the center of gravity G of the door body 1. In this way, each of the N1 st couplers 4 corresponding to each of the M groups of door bodies 10 is disposed on both sides (the opening side S1 and the closing side S2) in the opening and closing direction S with respect to the gravity center G of the door body 1 corresponding to the 1 st coupler 4.
Each of the N × M1 st couplers 4 slides along the corresponding 1 st guide rail 2. Specifically, each of the N1 st couplers 4 corresponding to the respective door body groups 10 slides along the corresponding 1 st guide rail 2 of the N1 st guide rails 2.
In the following description, the 1 st coupler 4 coupled to the inner door body 1A is referred to as a "1 st inner coupler 4A", and the 1 st coupler 4 coupled to the outer door body 1B is referred to as a "1 st outer coupler 4B". The 1 st coupling member 41 of the 1 st inner coupling 4A is referred to as a "1 st inner coupling member 41A", and the 1 st coupling member 41 of the 1 st outer coupling 4B is referred to as a "1 st outer coupling member 41B".
As shown in fig. 3, the 1 st inner coupler 4A and the 1 st outer coupler 4B are arranged apart from each other in the front-rear direction D so as not to interfere with each other when sliding in the opening-closing direction S. The 1 st inner connector 4A slides along the rear guide rail 2R. On the other hand, the 1 st outer coupler 4B slides along the front guide rail 2F.
In the present embodiment, the front guide rail 2F and the rear guide rail 2R are fixed to the 1 st fixing member 21. The 1 st fixing member 21 has an inverted U-shaped cross-sectional shape when viewed in the opening/closing direction of the opening/closing direction S. The 1 st fixing member 21 includes a 1 st front fixing portion 21a and a 1 st rear fixing portion 21b facing the 1 st front fixing portion 21a at the rear side D2. The front guide rail 2F is fixed to the 1 st front fixing portion 21a so as to protrude from the surface of the rear side D2 of the 1 st front fixing portion 21a to the rear side D2. Further, the rear guide rail 2R is fixed to the 1 st rear fixing portion 21b so as to protrude from the surface of the front side D1 of the 1 st rear fixing portion 21b to the front side D1.
The 1 st inner connecting member 41A includes a 1 st inner sliding portion 411A that slides on the rear guide rail 2R, and a 1 st inner connecting portion 412A that connects the 1 st inner sliding portion 411A and the inner door body 1A.
In the present embodiment, the 1 st inner slide portion 411A is configured to hold the rear guide rail 2R from the front side D1. The 1 st inner slide 411A includes a plurality of rolling elements (not shown) disposed so as to sandwich the rear guide rail 2R from both the 1 st side W1 in the width direction and the 2 nd side W2 in the width direction. The 1 st inner slide portion 411A and the rear guide rail 2R of the present embodiment can be configured by a known linear motion guide.
In the present embodiment, the 1 st inner connecting portion 412A is formed in a plate shape extending to connect the 1 st inner sliding portion 411A and the inner door body 1A. The 1 st inner connecting portion 412A is connected to each of the end portion of the front side D1 of the 1 st inner slide portion 411A and the end portion of the 1 st side W1 of the inner door body 1A in the width direction.
The 1 st outer connecting member 41B includes a 1 st outer sliding portion 411B that slides on the front guide rail 2F, and a 1 st outer connecting portion 412B that connects the 1 st outer sliding portion 411B and the outer door body 1B.
In the present embodiment, the 1 st outer slide 411B is configured to hold the front guide rail 2F from the rear side D2. The 1 st outer slide 411B includes a plurality of rolling elements (not shown) disposed so as to sandwich the front guide rail 2F from both sides of the 1 st width direction W1 and the 2 nd width direction W2. The 1 st outer slide portion 411B and the front guide rail 2F of the present embodiment can be configured by a known linear motion guide.
In the present embodiment, the 1 st outer connecting portion 412B is formed in a plate shape extending so as to connect the 1 st outer sliding portion 411B and the outer door body 1B. The 1 st outer connecting portion 412B is connected to each of the surface of the rear side D2 of the 1 st outer slide portion 411B and the surface of the 1 st side W1 in the width direction of the outer door body 1B.
As described above, the 1 st inner coupler 4A and the 1 st outer coupler 4B are arranged apart from each other in the front-rear direction D so as not to interfere with each other when sliding in the opening-closing direction S. Therefore, as shown in fig. 2, even when the door body group 10 is in the open state, the 1 st inner coupler 4A and the 1 st outer coupler 4B do not interfere with each other. In the present embodiment, when the door body group 10 is in the open state, the two 1 st inner connecting members 41A and the two 1 st outer connecting members 41B overlap each other when viewed in the front-rear direction along the front-rear direction D, but do not overlap each other when viewed in the opening-closing width direction along the opening-closing width direction W.
As shown in fig. 1 and 2, the 2 nd guide rail 3 is formed to extend in the opening and closing direction S. The 2 nd guide rail 3 is disposed on the 2 nd side W2 in the width direction with respect to the M groups of door bodies 10.
Each of the N × M2 nd couplers 5 is coupled to a corresponding one 1 of the N × M door bodies 1. That is, 1 of the 2 nd couplers 5 is coupled to 1 of the door bodies 1. In the present embodiment, 1 of the 2 nd couplers 5 is coupled to the inner door 1A of each door group 10, and 1 of the 2 nd couplers 5 is coupled to the outer door 1B of each door group 10. In the present embodiment, each 2 nd coupler 5 includes two 2 nd coupling members 51.
In the following description, the 2 nd connector 5 connected to the inner door body 1A is referred to as a "2 nd inner connector 5A", and the 2 nd connector 5 connected to the outer door body 1B is referred to as a "2 nd outer connector 5B". The 2 nd coupling member 51 of the 2 nd inner coupling 5A is referred to as a "2 nd inner coupling member 51A", and the 2 nd coupling member 51 of the 2 nd outer coupling 5B is referred to as a "2 nd outer coupling member 51B".
Each of the N × M2 nd couplers 5 slides along the 2 nd guide rail 3. In the present embodiment, the two 2 nd inner couplers 5A and the two 2 nd outer couplers 5B slide along the 1 nd 2 nd guide rail 3.
As shown in fig. 2, in the present embodiment, the 2 nd inner joint 5A and the 2 nd outer joint 5B are arranged so as not to overlap each other when viewed in the front-rear direction along the front-rear direction D when the door body group 10 is in the open state. Further, the position of the 2 nd outer connector 5B in the opening and closing direction S relative to the outer door body 1B is on the open side S1 with respect to the position of the 2 nd inner connector 5A in the opening and closing direction S relative to the inner door body 1A. In the example shown in fig. 1, the two 2 nd inner connecting members 51A are disposed closer to the closing side S2 than the center of gravity G of the inner door body 1A. On the other hand, the two 2 nd outer connecting members 51B are disposed on both sides in the opening/closing direction S with respect to the center of gravity G so that the distances from the center of gravity G of the outer door body 1B are the same. Here, the distance between the inner closing position P1A and the inner opening position P2A of the inner door body 1A is longer than the distance between the outer closing position P1B and the outer opening position P2B of the outer door body 1B.
In this way, the N2 nd couplers 5 corresponding to each of the M door body groups 10 are arranged so as not to overlap each other when viewed in the front-rear direction along the front-rear direction D in the open state, and are positioned on the open side S1 as the distance between the closed position and the open position of the corresponding door body 1 becomes longer. Therefore, even in the structure in which the 2 nd couplers 5 all slide along the 1 nd 2 nd guide rail 3, the 2 nd couplers 5 do not interfere with each other.
As shown in fig. 4, in the present embodiment, the 2 nd guide rail 3 is fixed to the 2 nd fixing member 31. The 2 nd fixing member 31 has a U-shaped cross-sectional shape when viewed in the opening and closing direction of the opening and closing direction S. The 2 nd fixing member 31 includes a 2 nd front fixing portion 31a and a 2 nd rear fixing portion 31b facing the 2 nd front fixing portion 31a at a rear side D2. The 2 nd guide rail 3 is fixed to the 2 nd front fixing portion 31a so as to protrude from the surface of the rear side D2 of the 2 nd front fixing portion 31a to the rear side D2.
As shown in fig. 4 and 5, the 2 nd inner connecting member 51A includes a 2 nd inner sliding portion 511A that slides on the 2 nd guide rail 3, and a 2 nd inner connecting portion 512A that connects the 2 nd inner sliding portion 511A and the inner door body 1A.
In the present embodiment, the 2 nd inner slide portion 511A is configured to hold the 2 nd guide rail 3 from the rear side D2.

In the example shown in fig. 4, the outer slide coupling 514B has the same shape as the inner slide coupling 514A.
As shown in fig. 1 and 2, in the present embodiment, the door apparatus 100 further includes a power transmission mechanism 30 that transmits power to the M-group door body group 10.
The power transmission mechanism 30 is disposed on at least one of the width direction 1 st side W1 and the width direction 2 nd side W2 with respect to the M-group door body group 10. In the present embodiment, the power transmission mechanism 30 is disposed on the 2 nd side W2 in the width direction with respect to the two door body groups 10.
The power transmission mechanism 30 includes N pulley pairs 6, N belts 7, and N × M belt couplers 8. In the present embodiment, the power transmission mechanism 30 includes two pulley pairs 6, two belts 7, and 4 belt couplers 8(N is 2, and M is 2).
Each of the N pulley pairs 6 is constituted by the 1 st pulley 61 and the 2 nd pulley 62. That is, the N pulley pairs 6 include N1 st pulleys 61 and N2 nd pulleys 62.
The N1 st pulleys 61 are coaxially arranged. Further, the N1 st pulleys 61 are configured to rotate integrally. As shown in fig. 4, in the present embodiment, the 1 st shaft 61a, which is a common rotation shaft of the two 1 st pulleys 61, is coupled to the two 1 st pulleys 61. The 1 st shaft 61a is rotationally driven by a motor 63 fixed to the 2 nd rear fixing portion 31b of the 2 nd fixing member 31. Also, as the 1 st shaft 61a rotates, the two 1 st pulleys 61 rotate. In the present embodiment, the 1 st shaft 61a is disposed in the front-rear direction D from the 2 nd rear fixing portion 31b to the 2 nd front fixing portion 31a of the 2 nd fixing member 31.

In the present embodiment, the 2 nd shaft 62a, which is a common rotation shaft of the two 2 nd pulleys 62, is coupled to the two 2 nd pulleys 62. With the rotation of the 2 nd shaft 62a, the two 2 nd pulleys 62 rotate. In the present embodiment, the 2 nd shaft 62a is arranged along the front-rear direction D.
The N1 st pulleys 61 and the N2 nd pulleys 62 are arranged apart from each other in the opening/closing direction S. In the present embodiment, the two 1 st pulleys 61 and the two 2 nd pulleys 62 are disposed on the rear side D2 of the 2 nd guide rail 3 (see fig. 4). That is, in the present embodiment, the 2 nd guide rail 3 is disposed further to the front side D1 than the two pulley pairs 6. In this way, the 2 nd guide rail 3 is disposed on one side in the front-rear direction D with respect to the N pulley pairs 6.
The outer diameters of the 1 st pulley 61 and the 2 nd pulley 62 constituting the 1 pair pulley pair 6 are the same. Further, the N1 st pulleys 61 have outer diameters different from each other. Of course, the N2 nd pulleys 62 also have different outer diameters from each other. In the present embodiment, one of the two 1 st pulleys 61 has the same outer diameter as one of the two 2 nd pulleys 62. The other outer diameter of the two 1 st pulleys 61 is the same as the other outer diameter of the two 2 nd pulleys 62. Further, the outer diameters of the two 1 st pulleys 61 are different from each other. The outer diameters of the two 2 nd pulleys 62 are also different from each other.
In the following description, the two 1 st sheaves 61 having a large outer diameter are referred to as "1 st large diameter sheaves 61L", and the two 1 st sheaves 61 having a small outer diameter are referred to as "1 st small diameter sheaves 61S". The two 2 nd sheaves 62 having a larger outer diameter are referred to as "2 nd large diameter sheaves 62L", and the two sheaves having a smaller outer diameter are referred to as "2 nd small diameter sheaves 62S".
In the present embodiment, the 1 st small-diameter sheave 61S is disposed further toward the front side D1 than the 1 st large-diameter sheave 61L. The 2 nd small-diameter pulley 62S is disposed further toward the front side D1 than the 2 nd large-diameter pulley 62L.
Each of the N belts 7 is an endless belt in a ring shape. Each of the N belts 7 is wound around the pulley pair 6. That is, the 1 belt 7 is wound around and hung between the 1 st pulley 61 and the 2 nd pulley 62 constituting the 1 pair of pulley pairs 6.
In the following description, the belt 7 wound around the 1 st large-diameter pulley 61L and the 2 nd large-diameter pulley 62L is referred to as a "large-diameter belt 7L", and the belt 7 wound around the 1 st small-diameter pulley 61S and the 2 nd small-diameter pulley 62S is referred to as a "small-diameter belt 7S".
Each of the N × M belt couplers 8 is configured to couple 1 door 1 corresponding to the N × M doors 1 and the belt 7 corresponding to the door 1 to each other. In the present embodiment, 1 belt coupler 8 couples the inner door body 1A and the large diameter belt 7L of each door body group 10, and 1 belt coupler 8 couples the outer door body 1B and the small diameter belt 7S of each door body group 10. In the following description, the belt coupler 8 that couples the inner door body 1A and the large-diameter belt 7L to each other is referred to as "large-diameter belt coupler 8L", and the belt coupler 8 that couples the outer door body 1B and the small-diameter belt 7S to each other is referred to as "small-diameter belt coupler 8S".
Here, the belt 7 wound around the pulley pair 6 is formed with a pair of straight portions extending in the opening and closing direction S. The moving directions of the pair of straight portions of the belt 7 when rotationally driven are different from each other. In the present embodiment, one of the two inner door bodies 1A is coupled to one of the pair of straight portions of the large-diameter belt 7L via the large-diameter belt coupler 8L. On the other hand, the other of the two inner door bodies 1A is connected to the other of the pair of straight portions of the large-diameter belt 7L via the large-diameter belt connector 8L. One of the two outer door bodies 1B is connected to one of the pair of straight portions of the small-diameter belt 7S via a small-diameter belt connector 8S. On the other hand, the other of the two outer door bodies 1B is connected to the other of the pair of straight portions of the small-diameter belt 7S via the small-diameter belt connector 8S.
Further, the outer diameter of each of the N1 st pulleys 61 is set in correspondence with the distance between the closing position and the opening position of the door body 1 corresponding to the 1 st pulley 61. In the present embodiment, the outer diameter of each of the 1 st large-diameter pulley 61L and the 2 nd large-diameter pulley 62L is set in proportion to the distance between the inside closing position P1A and the inside opening position P2A of the inside door body 1A. The outer diameter of each of the 1 st and 2 nd small- diameter pulleys 61S and 62S is set in proportion to the distance between the outer closing position P1B and the outer opening position P2B of the outer door body 1B.
In this way, in the present embodiment, when the 1 st large-diameter pulley 61L and the 1 st small-diameter pulley 61S are rotationally driven via the 1 st shaft 61a by the motor 63, one of the two door body groups 10 moves so as to approach or separate from the other. At this time, since the outer diameter of each 1 st pulley 61 is set as described above, each door 1 moves between the closed position and the open position appropriately even if the distance between the inner closing position P1A of the inner door 1A and the inner opening position P2A is different from the distance between the outer closing position P1B of the outer door 1B and the outer opening position P2B.
In the present embodiment, each belt coupler 8 includes two belt coupling members 81. In the following description, the belt connecting member 81 of the large-diameter belt connector 8L is referred to as a "large-diameter belt connecting member 81L", and the belt connecting member 81 of the small-diameter belt connector 8S is referred to as a "small-diameter belt connecting member 81S".

The large-diameter side coupling 813L is coupled to an end of the large-diameter side fixing portion 811L on the 2 nd side W2 in the width direction. In the example shown in fig. 4, the large diameter side coupler 813L projects from the coupling portion between the large diameter side coupler 813L and the large diameter side fixing portion 811L toward the front side D1, and projects therefrom toward the 1 st side W1 in the width direction. The extended end of the large-diameter side coupling 813L is coupled to the end of the rear side D2 of the 2 nd inner sliding portion 511A.
Further, in the present embodiment, the large-diameter side connecting portion 812L includes the 2 nd inner connecting portion 512A of the 2 nd inner connecting member 51A as a component. That is, the large-diameter belt connecting member 81L shares the 2 nd inner connecting portion 512A and the 2 nd inner connecting member 51A. In the example shown in fig. 4, the inner slide coupling 514A, the large diameter side coupling 813L, and the 2 nd inner slide portion 511A are fixed to each other by bolt fastening in a state where the coupling portion of the inner slide coupling 514A to the 2 nd inner slide portion 511A is in contact with the coupling portion of the large diameter side coupling 813L to the 2 nd inner slide portion 511A from the rear side D2.
In this way, in the present embodiment, the large-diameter belt coupling member 81L is configured to utilize a part of the 2 nd inner coupling member 51A. Therefore, the 2 nd inner connector 5A connected to the same inner door body 1A overlaps the arrangement region in the opening/closing direction S of the large-diameter belt connector 8L.
As shown in fig. 4, the small-diameter-tape connecting member 81S includes a small-diameter-side fixing portion 811S to which the small-diameter tape 7S is fixed, and a small-diameter-side connecting portion 812S that connects the small-diameter-side fixing portion 811S and the outer door body 1B.
In the present embodiment, the small-diameter side fixing portion 811S is configured to hold a straight portion of the small-diameter tape 7S in a sandwiched manner from both the 1 st side W1 in the width direction and the 2 nd side W2 in the width direction.
In the present embodiment, the small-diameter side connecting portion 812S includes a small-diameter side coupling 813S coupled to the small-diameter side fixing portion 811S. In the present embodiment, the small-diameter-side coupling 813S is formed in a plate shape. The small-diameter side coupling 813S is coupled to an end of the small-diameter side fixing portion 811S on the 2 nd side W2 in the width direction. In the example shown in fig. 4, the small-diameter side coupler 813S projects from the coupling portion between the small-diameter side coupler 813S and the small-diameter side fixing portion 811S toward the front side D1, and projects therefrom toward the 1 st side W1 in the width direction. Further, the projecting end of the small-diameter side coupling 813S is coupled to the end of the rear side D2 of the 2 nd outer sliding portion 511B.
Further, in the present embodiment, the small-diameter side connecting portion 812S includes the 2 nd outer connecting portion 512B of the 2 nd outer connecting member 51B as a component. That is, the small-diameter belt connecting member 81S shares the 2 nd outer connecting portion 512B and the 2 nd outer connecting member 51B. In the example shown in fig. 4, the outer slide coupling 514B, the small-diameter side coupling 813S, and the 2 nd outer slide portion 511B are fixed to each other by bolt fastening in a state where the coupling portion of the outer slide coupling 514B to the 2 nd outer slide portion 511B is in contact with the coupling portion of the small-diameter side coupling 813S to the 2 nd outer slide portion 511B from the rear side D2.
In this way, in the present embodiment, the small-diameter belt connecting member 81S is configured to utilize a part of the 2 nd outer connecting member 51B. Therefore, the 2 nd outer coupling 5B and the small diameter belt coupling 8S coupled to the same outer door body 1B overlap each other in the arrangement region in the opening/closing direction S.
As shown in fig. 4, in the present embodiment, the belt 7 and the door body 1 coupled to each other by the belt coupler 8 are disposed so as to overlap each other when viewed in the opening/closing width direction along the opening/closing width direction W. Specifically, the large-diameter belt 7L and the inner door body 1A are disposed so as to overlap each other when viewed in the opening/closing width direction along the opening/closing width direction W. Further, the small diameter belt 7S and the outer door body 1B are disposed so as to overlap each other when viewed in the opening/closing width direction along the opening/closing width direction W.

In this way, by setting one of the two types of guide rails (the 2 nd guide rail) provided in the guide mechanism to a guide rail common to the N × M door bodies, the number of guide rails can be reduced. Therefore, the size and manufacturing cost of the door device can be suppressed to be small.
The N × M2 nd couplers sliding along the 2 nd guide rail are arranged so that the N2 nd couplers corresponding to the respective door body groups do not overlap with each other when viewed in the front-rear direction in the open state, and are positioned on the open side as the distance between the closed position and the open position of the corresponding door body becomes longer. Therefore, when the N2 nd couplers corresponding to the respective door body groups slide along the 2 nd guide rail, the 2 nd couplers can be prevented from interfering with each other. Therefore, even in the configuration in which the number of the 2 nd guide rails is 1 for the N × M doors, the N × M doors can appropriately move in the opening and closing direction.
As described above, the N2 nd couplers corresponding to the respective door groups are arranged so as to be positioned on the opening side as the distance between the closing position and the opening position of the corresponding door becomes longer. Therefore, each of the N2 nd couplers corresponding to each door body group may be coupled to a position of the door body corresponding to the 2 nd coupler, which is apart from the center of gravity in the opening and closing direction, and it may be difficult to support the door body in a balanced state by the 2 nd coupler alone. However, on the opposite side (the 1 st side in the width direction) from the 2 nd coupler side with respect to the M-group door body group, each of the N × M1 st couplers is disposed across both sides in the opening and closing direction with respect to the center of gravity of the door body corresponding to the 1 st coupler. Therefore, the door body can be supported in a balanced state from the 1 st side in the width direction by the 1 st coupler.
Preferably, the vehicle door further includes a power transmission mechanism disposed on at least one of the width direction 1 st side and the width direction 2 nd side with respect to the M groups of door bodies to transmit power to the M groups of door bodies, the power transmission mechanism including N pulley pairs and N belts, and a belt coupling device, wherein the N pulley pairs include N1 st pulleys that are coaxially arranged and integrally rotate and N2 nd pulleys that are coaxially arranged and integrally rotate, the N belts are wound around the N pulley pairs, respectively, the belt coupling device couples each of the N belts and the door body corresponding to the belt, outer diameters of the 1 st pulley and the 2 nd pulley that form the 1 pulley pair are the same, and an outer diameter of each of the N1 st pulleys is set in accordance with a distance between the closed position and the open position of the door body corresponding to the 1 st pulley.
According to this configuration, only one of the 1 st pulley and the 1 nd 2 nd pulley is rotated, and the N × M door bodies can be moved in the opening/closing direction via the N belts.
The outer diameters of the 1 st pulley and the 2 nd pulley constituting the 1 pair of pulleys are the same, and the outer diameter of each of the N1 st pulleys is set in accordance with the distance between the closed position and the open position of the door body corresponding to the 1 st pulley. Therefore, even in the configuration in which the N1 st pulleys and the N2 nd pulleys are coaxially arranged and integrally rotated, it is possible to appropriately move each of the N door bodies having different distances between the closed position and the open position to the closed position and the open position in each door body group.
Preferably, in the configuration including the power transmission mechanism, the power transmission mechanism is disposed on the 1 st side in the width direction with respect to the M groups of the door bodies, and the arrangement region in the opening/closing direction of the 1 st coupler and the belt coupler coupled to the same door body overlaps.
According to this aspect, the 1 st coupler and the belt coupler coupled to the same door body can be arranged close to each other in the opening/closing direction. This makes it easy to reduce the arrangement area of the 1 st coupler and the tape coupler in the opening and closing direction.
Further, it is preferable that the power transmission mechanism is disposed on the 2 nd side in the width direction with respect to the M groups of the door body groups, and the 2 nd connector coupled to the same door body overlaps with the arrangement region in the opening/closing direction of the belt connector.
According to this aspect, the 2 nd coupler and the belt coupler coupled to the same door body can be arranged close to each other in the opening/closing direction. Thus, when the N door bodies in each door body group move in the opening and closing direction, the 2 nd connector and the belt connector connected to the same door body can be made less likely to interfere with the 2 nd connector and the belt connector connected to another door body.
Further, it is preferable that the power transmission mechanism is disposed on the 2 nd side in the width direction with respect to the M groups of the door bodies, and the 2 nd guide rail is disposed on the one side in the front-rear direction with respect to the N pulley pairs.
According to this configuration, the 2 nd guide rail and the N pulley pairs can be easily arranged 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 suppressed to be small.
Further, it is preferable that the belt and the door body coupled to each other by the belt coupler are disposed so as to overlap each other when viewed in an opening/closing width direction along the opening/closing width direction.
According to this aspect, the belt and the door body coupled to each other by the belt coupler can be disposed close to each other in the front-rear direction. Therefore, the dimension of the door device in the front-rear direction can be suppressed to be small.
Preferably, the opening/closing direction is a direction along the vertical direction, and the door further includes a counterweight guide mechanism and N counterweight pieces, the N counterweight pieces being respectively connected to N belts so as to be balanced with respect to the N door bodies, the counterweight guide mechanism guiding the N counterweight pieces, the counterweight guide mechanism including a counterweight guide rail extending in the opening/closing direction, and a counterweight coupler connected to each of the N counterweight pieces and sliding along the counterweight guide rail.
According to this aspect, the N balance weights are coupled to the N belts, respectively, so as to be balanced with respect to the N door bodies. This makes it possible to reduce the driving force required to move each of the N door bodies in the opening/closing direction.
Further, according to the present configuration, each of the N balance weights is configured to move along the weight guide rail via the weight coupler. Thus, when the N door bodies move in the opening and closing direction, the N balance weights can also move in the opening and closing direction appropriately.
