In the present embodiment, when the first opening / closing body D1 and the second opening / closing body D2 are moved from the closed position to the open position, the opening / closing body is operated by driving the drive unit Dr and operating the wire W. Open D. Similarly, when closing the opening / closing body D from the open position to the closed position, the drive portion Dr is driven to operate the wire W.

  In the present embodiment, the first opening / closing body D1 is opened / closed by the first wire W1 operated by the first drive unit Dr1. The second opening / closing body D2 is operated by the second wire W2 operated by the second drive unit Dr2. Hereinafter, the first drive unit Dr1 and the first wire W1 for driving the first opening / closing body D1 will be described as an example, but the second drive unit Dr2 and the second wire W2 have the same configuration. Therefore, description is omitted.

  The first drive unit Dr1 generates a driving force for opening and closing the opening / closing body D1, and operates the first wire W1. The drive unit Dr1 is not particularly limited as long as the wire W1 can be operated. For example, as shown in FIG. 2, the drive unit Dr1 can be rotated forward and backward by the motor MT, and the end of the wire W1 is locked. And a drum DM around which the wire W1 is wound. In the present embodiment, as shown in FIGS. 1 and 2, the drive unit Dr1 is provided on the upper surface of the opening / closing body opening / closing mechanism M, but the position where the drive unit Dr1 is provided is not particularly limited. The opening / closing body opening / closing mechanism M may include an operation device (not shown) such as a switch or a sensor for driving the drive unit Dr1. When the drive unit Dr1 is driven, the wire W1 is wound and fed out.

  As described above, the wire W is directly or indirectly connected to the upper portion of the opening / closing body D, and is driven by the drive unit Dr to move the opening / closing body D. In the present embodiment, the first wire W <b> 1 that opens and closes the first opening / closing body D <b> 1 is connected to the first support member 21. More specifically, the first wire W1 is composed of two wires, and one of the first wires W1 is connected to one end (second closed) of the first guide member 31 from the first drive unit Dr1. (Position guide portion 31b side). One wire is routed from one end of the first guide member 31 along the first guide member 31 and connected to the engagement portion E (see FIG. 3) of the first connection portion 21a. The other wire of the first wires W1 extends from the engaging portion E of the first connection portion 21a to the other end of the first guide member 31 (on the first closed position guide portion 31a side). The other end of 31 extends to the first drive unit Dr1.

  Although the kind of wire W used is not specifically limited, In this embodiment, the control cable is used. As shown in FIG. 2, the control cable includes an inner cable Wa routed in a loop between the drum DM of the drive unit Dr and the first connection portion 21 a, and the drive unit Dr and the first guide member 31. And an outer casing Wb provided between the one end and the other end. Between the both ends of the first guide member 31 and the outer casing Wb, a direction changing member 4 for changing the direction of the inner cable Wa is provided. The direction changing member 4 directs the inner cable Wa coming out of the outer casing Wb so as to extend along the first guide member 31. The direction changing member 4 is not particularly limited as long as the direction of the inner cable Wa can be changed and guided, and a tube-shaped guide member, a guide member having an arc surface, a pulley, or the like can be used.

  In the present embodiment, the wire W is moved by the drive of the drive unit Dr, the first connection portion 21a is moved along the first guide member 31, and the second connection portion 21b is moved along the second guide member 32. By moving, the first opening / closing body D1 is opened / closed. In addition, the wire W is moved by the drive of the drive portion Dr, the fourth connection portion 22b is moved along the second guide member 32, and the third connection portion 22a is moved along the first guide member 31. The second opening / closing body D2 is opened / closed. More specifically, when opening the first opening / closing body D <b> 1, when the drive unit Dr is driven, the wire W routed along the first guide member 31 is the second with respect to the first guide member 31. The opening / closing body D1 moves to the opening direction side of the moving direction X. When the wire W moves to the opening direction side, the first connecting portion 21a connected to the wire W moves in the moving direction of the first opening / closing body D1 along the first guide member 31, as shown in FIGS. Move to the opening direction side of X. In the present embodiment, the first connection portion 21a and the second connection portion 21b are connected via the first support member 21 such as the first extension portion 21d, the first attachment portion 21c, and the second extension portion 21e. Yes. Therefore, the second connection portion 21b moves along the second guide member 32 as the first connection portion 21a moves. When the first opening / closing body D1 is closed, an operation opposite to that at the time of opening is performed, and the first opening / closing body D1 is closed.

  Here, in the present embodiment, as shown in FIG. 2, the first closed position guide portion 31 a and the second closed portion guide portion 31 a and the second connected portion 21 b are respectively guided when the first opening and closing body D1 is opened and closed. It has a curvature different from that of the 3 closed position guide portion 32a. Moreover, in this embodiment, the 3rd connection part 22a and the 4th connection part 22b are each guided when opening / closing the 2nd opening-and-closing body D2, and the 2nd closed position guide part 31b and the 4th closed position guide part 32b differ. Has curvature. As described above, in the present embodiment, the two connection portions guided respectively by the first and second guide members 31 and 32 when the one opening / closing body D is opened and closed are guided by the closed position guide portions curved with different curvatures. The As shown in FIG. 10, when the first connection portion 21a is operated by the wire W1, a force F1 is received in the tangential direction of the curved surface of the first closed position guide portion 31a. At this time, since the first connecting portion 21a and the second connecting portion 21b are connected by the first support member 21, the second connecting portion 21b also has the same direction as the tangential force F1 in the first connecting portion 21a. The force F2 is added. In the present embodiment, the curvature of the third closed position guide portion 32a through which the second connection portion 21b is guided is different from that of the first closed position guide portion 31a. Therefore, when a force F2 in the same direction as the tangential force F1 in the first connection portion 21a is applied to the second connection portion 21b, as shown in FIG. 10, a portion of the second connection portion 21b is provided. The abutted body (for example, thrust roller TR) abuts on the abutting portion of the third closed position guide portion 32a (for example, the inner wall of the front surface portion 324 of the third closed position guide portion 32a). More specifically, as shown in FIG. 10, the force F2 applied to the second connection portion 21b is equal to the tangential force F21 of the third closed position guide portion 32a guiding the second connection portion 21b and the third force F21. It can be decomposed into a force F22 in a direction perpendicular to the tangential direction of the closed position guide portion 32a. The force F21 becomes a force for the second connecting portion 21b to move the third closed position guide portion 32a, and the force F22 is applied to the tangent to the curved surface of the third closed position guide portion 32a. It is a force that tries to move in the vertical direction. Therefore, a force F22 is applied to the second connection portion 21b along with the force F21 that moves the third closed position guide portion 32a and the contact body of the second connection portion 21b toward the contact portion of the third closed position guide portion 32a. . Accordingly, the second connecting portion 21b moves along the third closed position guide portion 32a while being pressed against the third closed position guide portion 32a. For this reason, the second connecting portion 21b moves stably along the curvature of the third closed position guide portion 32a, and swinging when the opening / closing body D is opened / closed is suppressed, thereby enabling smooth opening / closing. Further, when the opening / closing body D is opened / closed, the second connection portion 21b moves in the front-rear direction Z while maintaining contact with the contact portion on the same side (front side in the present embodiment) of the third closed position guide portion 32a. Therefore, swinging of the opening / closing body D during opening / closing is suppressed, and smooth opening / closing is possible. In the present embodiment, the contact body of the second connection portion 21b is shown as the thrust roller TR, but if the second connection portion 21b can move while contacting the third closed position guide portion 32a, Other configurations such as a low friction material may be used. In the present embodiment, the contact portion of the third closed position guide portion 32a is shown as the inner wall of the front surface portion 324 of the third closed position guide portion 32a, but may be the inner wall of the back surface portion 312.

  On the other hand, unlike this embodiment, for example, when the curvatures of the first closed position guide portion 31a and the third closed position guide portion 32a are the same, the open / close body D is relative to the front surface of the open / close body D in the closed position. While moving in the front-rear direction Z in a parallel state, it moves in the moving direction X of the opening / closing body. Therefore, a force is applied to one connecting portion in the tangential direction of the curved closed position guide portion by a wire, and when one connecting portion moves, the other connecting portion also bends in the same direction as one connecting portion. A force is applied in the tangential direction of the closed position guide. At this time, when the curvatures of the two closed position guide portions are the same, the other connection portion moves in the same direction as one of the connection portions driven by the wire, and the swing of the opening / closing body D is moved within the closed position guide portion. It cannot be held down by wall surfaces. Further, even if the other connecting portion comes into contact with the inner wall surface of the closed position guide portion, the connecting portion comes into contact with the front side in the front-rear direction Z, or comes into contact with the rear side. Since the direction is not fixed, it is difficult to regulate the swing of the opening / closing body D. Therefore, in order to suppress the swinging of the opening / closing body D, a driving force such as a handle is applied to a position of the opening / closing body D away from the guide member 3 (for example, an intermediate position in the vertical direction of the opening / closing body D). It is necessary to provide a site to act. In the present embodiment, the first closed position guide part 31a and the third closed position guide part 32a have different curvatures, and the second closed position guide part 31b and the fourth closed position guide part 32b have different curvatures. As a result, the direction of contact can be the same in the front-rear direction, so that the swinging can be regulated stably.

  In the present embodiment, the first closed position guide portion 31a and the third closed position guide portion 32a have different curvatures, so that the opening / closing body D is inclined with respect to the moving direction X as shown in FIG. While being opened and closed. When the opening / closing body D moves in the front-rear direction Z and the movement direction X in a state parallel to the movement direction X (when the curvature is the same), the opening / closing body D is supported on the upper side, The opening / closing body D swings around a parallel axis. On the other hand, in the present embodiment, as shown in FIG. 7, the opening / closing body D moves so as to be inclined with respect to an axis parallel to the moving direction X, and the first connecting portion 21 a and the second connecting portion 21 b The amount of movement in the direction Z is different. Therefore, swinging of the opening / closing body D around the axis parallel to the movement direction X is unlikely to occur.

  Note that “the curvatures are different” means that, of the two connecting portions that move when moving one opening / closing body D, a force F1 in the tangential direction of the closed position guide portion is applied from one wire to the other connecting portion. Sometimes, when a force F2 in the same direction as the force F1 is applied to the other connecting portion, the closed position guiding portion that guides the other connecting portion so that the force F2 applied to the other connecting portion can be received. The curvature of is different. The degree of the difference in curvature is not particularly limited as long as the force F2 can be received. Here, when the first closed position guide portion 31a moves from the closed position to the open position, the second opening / closing body side end portion of the first opening / closing body D1 and the first opening / closing body side end portion of the second opening / closing body D2 are arranged. The first opening / closing body D1 overlaps the second opening / closing body side end of the first opening / closing body D1 and the first opening / closing body side end of the second opening / closing body D2 in the X direction of FIG. 7 so as not to collide. It is preferable to have a curvature that moves in the Z direction by at least the thickness of the second opening / closing body D2 when moving to the position. At this time, the third closed position guide portion 32a is provided with the second connecting portion. It is preferable that the second connecting portion 21b has a curvature such that the second connecting portion 21b relatively moves while a part of 21b abuts the third closed position guide portion 32a.

  The curved surfaces of the first to fourth closed position guide portions 31a, 31b, 32a, and 32b are not limited to circular arc surfaces, and may be curved so that the opening / closing body D can be opened and closed. It may be a curved surface combining an ellipse or a plurality of arcs. In addition, the curvature in this specification can be made into the curvature of an arc in the case of an arc surface, and in the case of an ellipse or a combination of a plurality of arc surfaces, the first to fourth closed position guides formed as curved surfaces. It can be set as the average curvature in the portions 31a, 31b, 32a, and 32b.

  In the present embodiment, the curvature of the first closed position guide portion 31a and the curvature of the fourth closed position guide portion 32b are larger than the curvatures of the second closed position guide portion 31b and the third closed position guide portion 32a. . In this case, as shown in FIG. 7, when the opening / closing body D is opened, the opening direction side of the opening / closing body D moves forward in the front-rear direction Z first with respect to the closing direction side. Therefore, when the openable / closable body D is opened and closed, it is easy to open and close so as not to collide with each other, and when the two open / close bodies D are in the closed position as shown in FIG. The interval in the movement direction X can be shortened.

  Moreover, in this embodiment, as FIG. 2-4 shows, the 1st connection part 21a and the 4th connection part 22b are respectively on the base end side of the 1st connection part 21a and the 4th connection part 22b. The first connection portion 21a and the fourth connection portion 22b have hinge portions H that swingably follow the first closed position guide portion 31a and the fourth closed position guide portion 32b, respectively. The second connection portion 21b and the third connection portion 22a are fixed to the first support member 21 and the second support member 22, respectively. In this case, by having the hinge portion H, even when the curvatures of the first and fourth closed position guide portions 31a and 32b are large, the hinge portion H swings along the first and fourth closed position guide portions 31a and 32b. The first and fourth connecting portions 21a and 22b can easily follow the curve. Further, the second and third connecting portions 21b and 22a are moved to follow by being fixed to the first and second support members 21 and 22 without providing a swinging member such as a hinge portion. The second and third connection portions 21b and 22a do not wobble when moving the second and third closed position guide portions 31b and 32a, and the swinging of the opening / closing body D can be further suppressed.

  In the present embodiment, the second closed position guide portion 31b has a second closed position guide bottom surface portion on which the vertical rolling element R3 of the third connection portion 22a rolls, and the third closed position guide portion 32a is The second connecting portion 21b has a third closed position guide bottom surface portion 321a (see FIG. 10) on which the vertical rolling element R2 rolls. The vertical rolling element R3 of the third connection portion 22a and the vertical rolling element R2 of the second connection portion 21b move in the closing direction or the opening direction near the closed positions of the first opening / closing body D1 and the second opening / closing body D2. At this time, the second closed position guide bottom surface portion 321a and the third closed position guide bottom surface portion 321a move in a direction having an angle with the rolling direction. Specifically, the direction in which the vertical rolling element R2 moves from the two-dot chain line state shown in FIG. 10 to the solid line state is the rolling direction of the vertical rolling element R2 (vertical rolling element R2 in FIG. 10). In a direction perpendicular to the rotation axis of As a result, the rolling elements R2 and R3 slide sideways on the second closed position guide bottom surface portion and the third closed position guide bottom surface portion 321a in the vicinity of the closed position of the opening / closing body D. Therefore, it is possible to easily follow the large movement of the rolling elements R1 and R4 on the first closed position guide portion 31a and the fourth closed position guide portion 32b, and the side slip becomes resistance to swinging. The swinging of the opening / closing body D can be suppressed. In the present embodiment, the rolling elements R2 and R3 are slid on the bottom surfaces of the second and third closed position guide portions 31b and 32a having a small curvature, the sideslip width is small, and the rolling elements R2 and R3 are moved. Is stable.

  Further, in the present embodiment, as shown in FIG. 9, when the opening / closing body D is opened, the first extending portion 21d and the fourth extending portion 22e intersect each other. The opening / closing body D can be opened without interference between the existing portion 21d and the fourth extending portion 22e. In this way, the first extending portion 21d and the fourth extending portion 22e intersect each other so as not to interfere with each other, thereby providing two connecting portions (for example, the first extending portion) provided on one support member. In the case of the first support member 21 of the opening / closing body D1, the interval between the first and second connection portions 21a, 21b) can be increased. By widening the interval between the connecting portions that support the opening / closing body D, the weight of the opening / closing body D can be easily supported, and the support state of the opening / closing body D is stabilized. Then, by widening the interval between the connecting portions that support the opening / closing body D, a rotational moment around an axis perpendicular to the surface of the opening / closing body D is less likely to occur. Therefore, when the opening / closing body D is opened / closed, the opening / closing body D is less likely to rattle, and the opening / closing body D can be moved more smoothly.

  Further, in the present embodiment, as shown in FIG. 2, the distance between two connection portions provided on one support member is increased by the configuration of the first and fourth extending portions 21d and 22e described above. be able to. Therefore, the length of the 1st and 2nd guide members 31 and 32 can be shortened. Therefore, according to the present embodiment, the opening / closing body D can be stably supported, and the lengths of the first and second guide members 31 and 32 can be shortened. Space becomes possible.

  Moreover, in this embodiment, the 1st and 2nd guide members 31 and 32 are arrange | positioned so that it may have the overlap area | region OL mentioned above. Thereby, for example, the first and second guide members 31 and 32 are compared with the case where the first and second guide members 31 and 32 are shifted horizontally in the front-rear direction Z (the vertical direction in FIG. 2) of the opening member 1. 2 The space occupied in the front-rear direction Z of the guide members 31 and 32 can be reduced. Therefore, for example, when installing other members (not shown) on the upper surface of the opening member 1 or the like, a wide installation space can be secured. In the present embodiment, the second guide member 32 is disposed on the upper side and the first guide member 31 is disposed on the lower side. However, the vertical relationship between the first guide member 31 and the second guide member 32 is reversed. Thus, the first guide member 31 and the second guide member 32 may be arranged.
