Further, in FIG. 4, in order to make it easy to distinguish the configuration of each part, the first cable 21 is shown by a two-dot chain line, and the second cable 22 is not shown.

As shown in FIG. 4, two leading carriages 33 are arranged for each set of first cables 21. Each leading carriage 33 may have a position sensor (not shown) that detects the position in the first direction D1. The leading carriage 33a of one of the two leading carriages 33 (hereinafter, referred to as the first leading carriage) 33a is arranged on the inner peripheral surface 103a side. Further, the other traveling carriage (hereinafter, referred to as a second leading carriage) 33b is arranged on the inner peripheral surface 103b side.

The first leading carriage 33a moves in the section of the first cable 21 from the inner peripheral surface 103a to the central portion of the opening 103. Of the film members 10 arranged on the inner peripheral surface 103a side, the end portion on the center side of the first direction D1 (hereinafter, referred to as the front end side end portion 11) is fixed to the first leading carriage 33a.

The first leading carriage 33a moves the leading end portion 11 of the film member 10 in the traveling direction by traveling in the first direction D1. For example, when the first leading carriage 33a moves from the inner peripheral surface 103a side to the center side of the opening 103, the leading end portion 11 of the film member 10 moves to the center side of the opening 103 according to the first leading carriage 33a. .. Therefore, the film member 10 extends and spreads in the first direction D1. Further, for example, when the first leading carriage 33a moves from the center side of the opening 103 to the inner peripheral surface 103a side, the leading end portion 11 of the film member 10 moves to the inner peripheral surface 103a side according to the first leading carriage 33a.

The second leading carriage 33b moves in the section of the first cable 21 from the inner peripheral surface 103b to the central portion of the opening 103. Of the film members 10 arranged on the inner peripheral surface 103b side, the end portion on the center side of the first direction D1 (hereinafter, referred to as the front end side end portion 12) is fixed to the second leading carriage 33b.

The second leading carriage 33b moves the leading end portion 12 of the film member 10 in the traveling direction by traveling in the first direction D1. For example, when the second leading carriage 33b moves from the inner peripheral surface 103b side to the center side of the opening 103, the leading end portion 12 of the film member 10 moves to the center side of the opening 103 according to the second leading carriage 33b. .. Therefore, the film member 10 extends and spreads in the first direction D1. Further, for example, when the second leading carriage 33b moves from the center side of the opening 103 to the inner peripheral surface 103b side, the leading end portion 12 of the film member 10 moves to the inner peripheral surface 103b side according to the second leading carriage 33b. To do. Therefore, the film member 10 is folded in the first direction D1 and contracts.

A plurality of intermediate bogies 34 are provided on the inner peripheral surface 103a side and the inner peripheral surface 103b side in one set of the first cables 21. The intermediate bogie 34 provided on the inner peripheral surface 103a side is arranged between the inner peripheral surface 103a and the first leading bogie 33a, and travels in the section between the inner peripheral surface 103a and the first leading bogie 33a. Further, the intermediate bogie 34 provided on the inner peripheral surface 103b side is arranged between the inner peripheral surface 103b and the second leading bogie 33b, and travels in the section between the inner peripheral surface 103b and the second leading bogie 33b. ..

The number of intermediate bogies 34 is set for each first cable 21, for example, according to the length of the first cable 21 in the first direction D1. For example, in the first cable 21 arranged at the center of the second direction D2 and its vicinity thereof, since the length of the first direction D1 is relatively long, a large number of intermediate carriages 34 are arranged. On the other hand, in the first cable 21 arranged at the end of the second direction D2 and its vicinity, the length of the first direction D1 is relatively short, so that the number of intermediate carriages 34 is small.

The traveling carriage driving unit 32 includes a wire 35, a wire driving unit 36, a pulley 37, a ridge cable 38, a ridge cable adjusting unit 39, and a moving pulley 40. Further, the traveling bogie drive unit 32 has a control unit (not shown) that controls each unit. The wire 35 connects the first leading carriage 33a and the second leading carriage 33b. The wire 35 is formed, for example, in an endless shape, and is bridged between a wire driving unit 36 arranged on the inner peripheral surface 103a side and a pulley 37 arranged on the inner peripheral surface 103b side. The wire drive unit 36 may be arranged on the inner peripheral surface 103b side, and the pulley 37 may be arranged on the inner peripheral surface 103a side.

The wire 35 is moved in the circumferential direction by the wire driving unit 36. As the wire 35 moves in the circumferential direction, the first leading carriage 33a and the second leading carriage 33b move in conjunction with each other. When one of the wires 35 is arranged at the center of the first direction D1 of the opening 103, the first leading carriage 33a and the second leading carriage 33b are in contact with the first direction D1 at the central portion. They are connected in a different positional relationship. In such a positional relationship, for example, in a state where the endless wire 35 is extended in one direction, the first leading carriage 33a is connected to one end and the second leading carriage 33b is connected to the other end. Is feasible. When the wire 35 is moved around by connecting in this way, for example, the first leading carriage 33a and the second leading carriage 33b are brought into contact with the first direction D1 at the center of the first direction D1 of the opening 103. Can be in a dolly state.

The moving pulley 40 can move in the first direction D1 along a rail (not shown). The rail is arranged along the inner peripheral surfaces 103a and 103b of the opening 103.

Further, each ridge cable 38 is provided with a lock portion 60 at the extension portion 38a. The lock portion 60 is a portion to which the locking portion 70 described later is locked. One lock portion 60 is arranged on each side of the second direction D2 of the stretched portion 38a. The lock portion 60 will be described later.

The ridge cable adjusting unit 39 adjusts the length of the extension portion 38a. The ridge cable adjusting unit 39 adjusts the length of the extending portion 38a to move each intermediate bogie 34 connected to the extending portion 38a in the first direction D1. That is, the ridge cable adjusting unit 39 adjusts the length of the extension portion 38a to synchronize the intermediate bogies 34 arranged on the different first cables 21 and move them in the first direction D1. Further, the ridge cable adjusting portion 39 adjusts the length of the stretched portion 38a to arrange the position of the lock portion 60 at a predetermined target position P (described later) in a state where the film member 10 is closed.

FIG. 5 is a diagram showing a state in which the film member 10 is in the process of opening and closing. As shown in FIG. 5, for example, when closing the roof device 100, the control unit orbits the wire 35 by the wire driving unit 36. As a result, the first leading carriage 33a moves from the position on the inner peripheral surface 103a side to the center side of the opening 103. Further, the second leading carriage 33b moves from the position on the inner peripheral surface 103b side to the center side of the opening 103. At this time, the control unit can move the film member 10 so that the curvatures of the leading end portions 11 and 12 are gradually reduced by individually adjusting the orbiting speed of the wire 35 for each wire driving unit 36. it can.

Further, when the first leading carriage 33a and the second leading carriage 33b move to the center side of the opening 103, the control unit opens the intermediate carriage 34 for each first cable 21 in the order of proximity to the leading carriage 33. Move to the center side of 103. In this case, the control unit gradually shortens the length of the extension portion 38a by the ridge cable adjusting unit 39. As a result, the intermediate bogies 34 adjacent to the second direction D2 are synchronized and smoothly move to the first direction D1. Further, the control unit moves the moving pulleys 40 arranged at both ends of the second direction D2 in synchronization with the first direction D1 in accordance with the movement of the first leading carriage 33a and the second leading carriage 33b. By this operation, the extension portion 38a hung on the moving pulley 40 moves in parallel with the first direction D1, and the intermediate bogie 34 moves more smoothly. Further, as the length of the extension portion 38a is shortened, the position of the lock portion 60 moves toward the end portion side in the second direction D2.

FIG. 6 is a diagram showing a state of the membrane member driving unit 30 when the membrane member 10 is closed. As shown in FIG. 6, when the roof device 100 is closed, the first leading carriage 33a and the second leading carriage 33b are connected at the central portion of the opening 103 in the first direction D1 and are on the inner peripheral surface 103a side. The leading end 11 of the film member 10 and the leading end 12 of the film member 10 on the inner peripheral surface 103b side are joined without a gap. As a result, the opening 103 is closed by the film member 10 so that rain or the like does not leak. Further, the intermediate bogies 34 adjacent to each other in the second direction D2 are arranged on a straight line parallel to the second direction D2. Further, the moving pulley 40 is arranged at a predetermined position when the membrane member 10 is closed. Note that FIG. 6 schematically shows the configuration of each part, so that the traveling carriage 31 on the inner peripheral surface 103a side and the traveling carriage 31 on the inner peripheral surface 103b side are displaced in the second direction D2. However, since they actually travel on the same first cable 21, the positions of the second directions D2 are the same. Further, the lock portion 60 provided in the extension portion 38a is arranged at or near the preset target position P.

FIG. 7 is a diagram showing a configuration when the end portion of the opening 103 in the second direction D2 is viewed from the first direction D1. FIG. 7 shows a state when the film member 10 is closed. As shown in FIG. 7, when the film member 10 is closed, the stretched portion 38a is in a state where the lock portion 60 is arranged at or near the target position P on the inner peripheral surface of the opening 103. Further, on the inner peripheral surface of the opening 103, a locking portion 70 for locking to the locking member 60 and the moving pulley 40 are arranged. The moving pulley 40 has a main body portion 40a, a pulley portion 40b, a traveling portion 40c, and a driving portion 40d. In the moving pulley 40, the end portion of the extension portion 38a of the ridge cable 38 is hung on the pulley portion 40b fixed to the main body portion 40a. The traveling portion 40c is arranged inside the main body portion 40a, and can travel along the rail 43 by being driven by the driving portion 40d. The moving operation of the moving pulley 40 is controlled by a control unit (not shown).

By locking the lock portion 60 with the locking portion 70, the movement of the extension portion 38a in the extending direction is restricted. Therefore, the length and tension of the stretched portion 38a are maintained. FIG. 7 shows a state in which the lock portion 60 is locked to the locking portion 70. However, when the locking state by the locking portion 70 is released, the locking portion 60 has a stretched portion 38a. It becomes possible to move in the extending direction. The lock portion 60 has an annular member 61. The annular member 61 has a rectangular opening 62. The opening 62 is formed in a size that allows the hook member 71 of the locking portion 70 to be inserted.

FIG. 8 is a diagram showing an example of the lock portion 60. FIG. 8 shows a configuration when the lock portion 60 is viewed from the upper surface side. As shown in FIGS. 7 and 8, the annular member 61 is in a state where the opening 62 penetrates in the thickness direction, that is, in the direction in which the extension portion 38a extends and in the direction orthogonal to each of the first direction D1. There is. The thickness direction of the annular member 61 is the direction in which the hook member 71 is inserted. The annular member 61 has a locking surface 61a, side surfaces 61b and 61c, and a slope 61d on the inner peripheral portion of the opening 62. The locking surface 61a is a surface that is locked to the hook member 71. The locking surface 61a is arranged on the end side of the extension portion 38a in the second direction D2.

FIG. 9 is an enlarged cross-sectional view showing a part of the locking surface 61a. As shown in FIG. 9, the locking surface 61a has a shape curved so as to project toward the slope 61d from the end portion in the thickness direction of the annular member 61 to the central portion. Therefore, the locking surface 61a has a curved shape so as to project toward the hook member 71 when the hook member 71 is locked. The locking surface 61a is provided with a plurality of first teeth 65 arranged side by side in the thickness direction of the annular member 61.

Further, as shown in FIG. 8, the side surfaces 61b and 61c are arranged on both sides of the opening 62 in the first direction D1. The side surfaces 61b and 61c are arranged so as to be close to or in contact with both side surfaces of the hook member 71 in the first direction D1 when the hook member 71 described later is inserted into the opening 62. With this configuration, when the hook member 71 is inserted into the opening 62, the side surfaces 61b and 61c suppress the annular member 61 and the hook member 71 from being displaced relative to the first direction D1. Further, the slope 61d is arranged in a state of being inclined with respect to the thickness direction of the annular member 61. The slope 61d suppresses the hook member 71 from interfering with the annular member 61 when the hook member 71 is inserted into the opening 62.

On the other hand, as shown in FIG. 8, the locking portion 70 includes a hook member 71, an arm 72, a shaft member 73, a bearing portion 74, and a drive portion 76. The hook member 71 is inserted into the opening 62 of the annular member 61. The arm 72 is connected to the hook member 71. The shaft member 73 is fixed to the arm 72 and can rotate about an axis parallel to the first direction D1. The bearing portion 74 rotatably supports the shaft member 73.

FIG. 10 is an enlarged view showing a part of the locking portion 70. As shown in FIG. 10, the hook member 71 has a locking surface 71a along an insertion direction (or an insertion / removal direction) from the root side to the tip side connected to the arm 72. The locking surface 71a is locked to the locking surface 61a of the annular member 61. The locking surface 71a is provided over a wider range than the thickness direction dimension of the annular member 61. Therefore, when the hook member 71 is inserted into the annular member 61, a part of the locking surface 71a is locked to the locking surface 61a of the annular member 61 in the insertion direction.

The locking surface 71a has a shape that is concavely curved over the entire insertion direction so as to correspond to the locking surface 61a. The locking surface 71a is provided with a plurality of second teeth 75 arranged side by side in the insertion direction. The second tooth 75 is formed so as to mesh with the first tooth 65 when the hook member 71 is inserted into the annular member 61. When the plurality of second teeth 75 are in mesh with the plurality of first teeth 65, the relative movement between the hook member 71 and the annular member 61 in the insertion direction of the hook member 71 is restricted. ..

In the locking portion 70 configured as described above, the hook member 71 rotates when the arm 72 rotates about the rotation axis of the shaft member 73. Therefore, for example, by setting a predetermined position on the movement path of the hook member 71 as the target position P and arranging the annular member 61 at the target position P, the hook member 71 is rotated to hook into the opening 62 of the annular member 61. The member 71 is inserted, and the locking surface 71a is locked to the locking surface 61a.

When the hook member 71 is locked to the annular member 61, the tensioning portion 38a is previously pulled toward the end side of the second direction D2 by the ridge cable adjusting portion 39, and the hook member 71 is inserted into the annular member 61. It is possible to prevent the first tooth 65 and the second tooth 75 from interfering with each other by eliminating the pulled state after the above.

FIG. 11 is a diagram showing an example of a state in which the locking portion 70 is locked to the locking portion 60.

A part of the arranged second teeth 75 meshes with the first teeth 65 of the locking surface 61a of the annular member 61. When the second tooth 75 meshes with the first tooth 65, the annular member 61 and the hook member 71 are restricted from relative movement or misalignment in the insertion / extraction direction. At this time, the connection surface 71b of the hook member 71 connected to the arm 72 is in a state parallel to the annular member 61. In this case, the annular member 61 is in a state of being arranged at the first position P1.

FIG. 13 is a diagram showing an example of a state in which the locking portion 70 is locked to the locking portion 60. Further, FIG. 14 is an enlarged view showing the positional relationship between the annular member 61 and the hook member 71. 13 and 14 show a state in which the tip portion of the hook member 71 is locked to the annular member 61.

As shown in FIGS. 13 and 14, when the tip portion of the hook member 71 is locked to the annular member 61, the hook member 71 is arranged at the tip of the plurality of second teeth 75 of the locking surface 71a. A part of the second teeth 75 meshes with the first teeth 65 on the locking surface 61a of the annular member 61. When the second tooth 75 meshes with the first tooth 65, the annular member 61 and the hook member 71 are restricted from relative movement or misalignment in the insertion / extraction direction. At this time, the connection surface 71b of the hook member 71 connected to the arm 72 is in a state of forming a predetermined angle α with respect to the annular member 61. Further, in this case, the annular member 61 is in a state of being arranged at the second position P2 deviated by the distance L from the first position P1.

As described above, in the hook member 71, the second tooth 75 is formed over a range in which the dimension in the insertion / removal direction is larger than the thickness of the annular member 61 and the thickness in the insertion / removal direction is longer than the thickness of the annular member 61. When the position of 60 is between the first position P1 and the second position P2, that is, within a predetermined distance L, the hook member 71 can be locked to the annular member 61. Therefore, when the target position P of the lock portion 60 is set between the first position P1 and the second position P2, even if the position of the lock portion 60 deviates from the target position P, the position of the lock portion 60 remains. When the hook member 71 is within the range from the first position P1 to the second position P2, the hook member 71 can be securely locked to the annular member 61. When the position of the lock portion 60 exceeds the range from the first position P1 to the second position P2, for example, the ridge cable adjusting portion 39 sets the position of the lock portion 60 to at least the first position. It may be adjusted between P1 and the second position P2.

As described above, the roof device 100 according to the present embodiment moves the intermediate carriage 34 in the first direction D1 while adjusting the length of the extension portion 38a of the ridge cable 38 according to the opening degree of the membrane member 10.

As a result, it is possible to suppress the deterioration of the runnability of the intermediate bogie 34, and it is possible to stably perform the opening / closing operation. Further, in the state where the film member 10 is closed, the lock portion 60 of the stretched portion 38a is arranged at a predetermined target position P, and the locking portion 70 is locked to the lock portion 60, whereby the roof device 100 is closed. Even when a load such as strong wind or snow is applied in this state, it is possible to prevent the intermediate carriage 34 from being displaced. Further, since the lock portion 60 can be locked to the lock portion 60 when at least the extension portion 38a is arranged within a predetermined distance L in the extending direction with respect to the target position P, the lock portion 60 is at the target position. Even if the distance is within a predetermined distance L from P, the lock portion 60 can be reliably locked, so that the position of the intermediate carriage 34 can be reliably suppressed from being displaced.

Further, in the roof device 100, in a state where the locking portion 70 is locked to the locking portion 60, the locking portion 70 restricts the movement of the locking portion 60 in the direction in which the extension portion 38a intersects in the extending direction. Even when a load such as strong wind or snow is applied while the lock portion 60 is locked, the locked state can be maintained.

Further, in the roof device 100, since the lock portion 60 has the annular member 61 and the locking portion 70 has the hook member 71 that can be inserted into the annular member 61, the hook member 71 can be inserted into the annular member 61. , The locking portion 70 can be securely locked to the locking portion 60.
