The inventor of the present application has studied the technology disclosed in Patent Document 1 and has recognized that there is room for improvement in the following points. The sliding door device of Patent Document 1 changes the thickness dimension of the door body by the guiding action of the guide portions on both sides in the door thickness direction. Since the guide portions on both sides need to act to change the thickness of the door body, they are likely to be subject to structural restrictions. Therefore, there was a problem in that the degree of freedom in designing the sliding door was small. Therefore, improvement of this problem is desired.

An example of the embodiment will be described below. Identical components are given the same reference numerals and redundant explanations will be omitted. In each drawing, for convenience of explanation, some of the constituent elements are omitted as appropriate, and their dimensions are enlarged or reduced as appropriate. The drawings should be viewed according to the direction of the symbols.

For convenience of explanation, as shown in the figure, an XYZ orthogonal coordinate system is defined in which a certain horizontal direction is the X direction, a horizontal direction perpendicular to the X direction is the Y direction, and a direction perpendicular to both, that is, the vertical direction is the Z direction. Further, the X direction may be referred to as the left-right direction or the opening/closing direction, the Y direction may be referred to as the door thickness direction, and the Z direction may be referred to as the up-down direction. Furthermore, the direction approaching the back side member 32, which will be described later, is sometimes referred to as the inside in the door thickness direction, and the direction away from the back side member 32, which will be described later, is sometimes called the outside in the door thickness direction. The notation of such directions does not limit the usage posture of the sliding door device 100, and the sliding door device 100 can be used in any posture depending on the purpose. In the example of FIG. 1, the X direction is along the facing direction of the sliding door 30, and the Y direction is along the facing direction of the sliding door 30.

(Structure) The sliding door device 100 includes a frame 10, a sliding door 30, and a connection mechanism 50. By moving in the X direction, the sliding door 30 can open and close the building opening 2 that penetrates the building wall surface 1 in the Y direction and opens into the building wall surface 1. Here, an example in which a building opening 2 is provided in the frame 10 is shown. 1 and 4(a) show a fully closed state in which the building opening 2 is completely closed by the sliding door 30. 2 and 4(b) show a partially closed state in which the building opening 2 is being opened and closed by the sliding door 30 and the building opening 2 is partially closed, and FIGS. 3 and 4(c) show the sliding door 30 indicates a fully open state in which the building opening 2 is completely opened.

The thickness of the sliding door 30 can be changed in cooperation with the connecting mechanism 50. Specifically, the sliding door 30 changes the door thickness in the process of transitioning between the fully closed state and the partially closed state, and maintains the door thickness in the process of transitioning between the partially closed state and the fully open state. The sliding door 30 decreases in thickness during the transition from the fully closed state to the partially closed state, and increases in thickness during the transition from the partially closed state to the fully closed state.

The frame 10 is fixed to a building frame (not shown). The frame body 10 surrounds the sliding door 30 and supports a back side member 32 of the sliding door 30, which will be described later, so as to be movable in the opening/closing direction. As shown in FIG. 4(a), the frame 10 includes a pair of frame units 10a provided on both sides in the door thickness direction, and a connection frame 10b connecting the pair of frame units 10a. The frame unit 10a includes an upper frame 11, a lower frame 12, and a pair of vertical frames 13. These are framed in a rectangular shape. The upper frame 11 extends in the X direction at the upper part of the frame body 10. The lower frame 12 extends in the X direction at the lower part of the frame body 10. A pair of vertical frames 13 extend in the Z direction from both ends of the upper frame 11 and the lower frame 12 so as to connect them.

As shown in FIG. 4(a), the building wall surface 1 is formed by an outer surface 3 facing outward in the Y direction of each of the pair of frame units 10a, and a partition wall 19 attached to each of the pair of frame units 10a. Ru. The space surrounded by the partition walls 19 on both sides and the vertical frame 13 on the right side constitutes a door pocket 4 that accommodates a sliding door 30.

The frame body 10 includes an intermediate horizontal frame 14, a partition frame 15, and a catcher 16. The intermediate horizontal frame 14 is provided between the pair of vertical frames 13. The building opening 2 is formed inside the lower frame 12, the left vertical frame 13, the intermediate horizontal frame 14, and the partition frame 15. The partition frame 15 extends in the Z direction between the upper frame 11 and the lower frame 12 at the center of the upper frame 11 and the lower frame 12. The catcher 16 is provided on the left vertical frame 13.

A door roller rail 17 is provided at the bottom of the intermediate horizontal frame 14 to suspend and hold each door roller 53a (see FIG. 9, etc.) of a door hanger 53 of a connection mechanism 50, which will be described later, so as to be movable in the X direction. The lower frame 12 is provided with a first guide rail 18 for guiding a steady rest 44 provided at the lower end of the sliding door 30. A glass partition wall 19 is installed between the partition frame 15 and the right vertical frame 13. The partition wall 19 may be made of a non-transparent material such as gypsum board or plywood. The steady rest 44 may be provided on the frame 10 or the floor material.

The catcher 16 is configured to be able to hold the sliding door 30 in the closed position. Here, the "closed position" refers to the position of the sliding door 30 when the sliding door device 100 is in a fully closed state or a partially closed state. The catcher 16 holds the sliding door 30 so as to maintain the closed position. The catcher 16 is configured to separate from the back side member 32 when a load in the opening direction that is greater than the holding force of the back side member 32 is applied to the back side member 32 while holding the back side member 32 of the sliding door 30, which will be described later. Ru. The catcher 16 of this embodiment is a magnet.

The catcher 16 can restrict further movement of the sliding door 30 in the closed position in the closing direction. Therefore, in addition to the function of holding the sliding door 30, the catcher 16 has the function of a stopper for the sliding door 30.

The sliding door 30 is arranged inside the frame 10. The sliding door 30 is configured so that its thickness can be changed. The sliding door 30 includes surface materials 31 provided on both sides in the door thickness direction, and a back side member 32 provided between the surface materials 31 on both sides. The sliding door 30 is attached to the frame 10 by, for example, a Kendon operation. The upper part of the sliding door 30 is fitted into a guide groove (not shown) of the intermediate horizontal frame 14. The sliding door 30 is supported by the frame 10 via a connecting mechanism 50 so as to be movable in the X direction.

The surface material 31 includes an upper stile 33, a lower stile 34, a pair of vertical stile 35, and a guide frame 36. The surface material 31 is a panel member in which a surface material 37 is attached to a rectangular frame. The upper stile 33 extends in the X direction above the surface material 31. The lower stile 34 extends in the X direction below the surface material 31. A pair of vertical frames 35 extend in the Z direction from both ends of the upper frame 33 and the lower frame 34 so as to connect them. The guide frame 36 extends between the pair of vertical frames 35 in the X direction. As shown in FIG. 9, the guide frame 36 has a second guide rail 36a for guiding a second roller 62 of a moving mechanism 58, which will be described later. The second guide rail 37 is formed on the lower surface of the guide frame 36 in the X direction. However, the present invention is not limited thereto, and the second guide rail 37 may be formed only in the movable region of the door thickness changing roller 65. The surface material 31 is movably supported with respect to the back side member 32 via a connection mechanism 50 .

The stile 35 on the left side of the facing material 31 has a grip 38 for the user to operate the sliding door 30. The grip portion 35a is formed by providing a long and thin rod-like member 38b in a cutout portion 38a formed in the center of the left vertical stile 35 in the Z direction so that the user can grip it with his or her hand. The rod-shaped member 38b extends in the Z direction so as to connect the upper vertical stile 35 and the lower vertical stile 35 separated by the cutout portion 38a.

By providing the grip portion 38, the user can easily apply a load to the sliding door 30 in the opening/closing direction by gripping the grip portion 38. Therefore, the sliding door 30 can be easily accommodated in the door pocket 4 in the partially closed state, and the sliding door 30 can be easily pulled out from the door pocket 4 in the opening direction in the fully open state. Furthermore, since the user can easily apply a load to the sliding door 30 in the door thickness direction by grasping the grip part 38, it is easy to move the surface material 31 outward in the door thickness direction when changing from a partially closed state to a fully closed state. can be pulled to.

The back side member 32 is disposed on the back side of the surface material 31 in the door thickness direction, and is connected to the frame 10 so as to be able to transmit a load in the door thickness direction. The back side member 32 is configured to move the sliding door 30 in the opening/closing direction by receiving a load in the opening/closing direction. The back side member 32 is supported by the frame 10 so as to be movable in the opening/closing direction. The back side member 32 supports the surface material 31 so as to be movable in the door thickness direction via a moving mechanism 58 which will be described later. The back side member 32 is made of metal and is held by the catcher 16 in a fully closed state or a partially closed state.

The back side member 32 includes an upper frame 39, a lower frame 40, a pair of vertical frames 41, a middle frame 42, and a guide portion 43. The upper frame 39 extends in the X direction at the upper part of the back side member 32. The lower frame 40 extends in the X direction at the lower part of the back side member 32. A pair of vertical frames 41 extend in the Z direction from both ends of the upper frame 39 and the lower frame 40 so as to connect them. The middle frame 42 extends between the pair of vertical frames 41 in the X direction. On the lower surface of the lower frame 40, a plurality of steady rests 44 are arranged apart from each other in the X direction. The steady rest 44 is placed on the first guide rail 18 of the frame 10.

The guide portions 43 are provided on the upper surface of both ends of the upper frame 39 of the back side member 32, respectively. As shown in FIG. 9, the guide section 43 has a third guide rail 45 for guiding a first roller 57 of a support 54, which will be described later.

The third guide rails 45 on both the left and right sides have a predetermined length in the opening/closing direction. When the first roller 57 moves from one end of the third guide rail 45 along the third guide rail 45 by this predetermined length dimension, the first roller 57 moves from one end of the third guide rail 45 to the third guide rail 45. The other end of the rail 45 is contacted. Due to this contact, the guide portion 43 receives a load in the opening/closing direction via the support 54.

The connection mechanism 50 connects the surface material 31 to the back side member 32 so as to be movable in the door thickness direction. The connection mechanism 50 moves the surface material 31 in the door thickness direction relative to the back side member 32 when a load in the door thickness direction is input to the surface material 31. The connection mechanism 50 includes a moving body 51 and a door thickness changing mechanism 52.

The movable body 51 is configured to be movable in the opening/closing direction together with the sliding door 30 when it is at the end position of its range of motion relative to the sliding door 30. The movable body 51 is configured to be movable relative to the sliding door 30 in the opening/closing direction within its movable range in response to an input load. The moving body 51 includes a door hanger 53, a support 54, a connector 55, and a connection member 56. The distance that the movable body 51 moves relative to the sliding door 30 corresponds to the length dimension of the third guide rail 45. The range of movement of the movable body 51 relative to the sliding door 30 is determined by the third guide rail 45.

The door hanger 53 is configured to be movable in the opening/closing direction by receiving a load in the opening/closing direction. When the door hanger 53 receives a load in the opening/closing direction, each door roller 53a of the door hanger 53 runs on the door roller rail 17. As a result, the sliding door 30 moves in the opening/closing direction, and the opening/closing operation is performed. The door hanger 53 is provided within the intermediate horizontal frame 14.

The support 54 connects the door hanger 53 and the sliding door 30 and supports the sliding door 30 so as to be slidable in the opening/closing direction. The supports 54 are provided at both ends of the door hanger 53, respectively. A first roller 57 is provided at the lower end of the support 54 . The first roller 57 is connected to the third guide rail 45 so as to be slidable in the opening/closing direction.

The connecting tool 55 connects the door hanger 53 and the connecting member 56. The connector 55 is provided at the center of the door hanger 53.

A load in the opening/closing direction is applied to the connecting member 56 from the drive device 20 via the connecting tool 55 . Both ends of the connecting member 56 are connected to left and right load converting mechanisms 60, which will be described later, of the door thickness changing mechanism 52, respectively. The connecting member 56 is arranged between the facing members 31 on both sides.

Since the door hanger 53, the support 54, the connector 55, and the connection member 56 are integrally connected, they move integrally in the opening/closing direction. Therefore, when the movable body 51 is moving relative to the sliding door 30 in the opening/closing direction within its movable range, that is, when the first roller 57 is moving between both ends of the third guide rail 45, When the sliding door 30 is closed, it moves relative to the sliding door 30 in the opening/closing direction. When the first roller 57 contacts the end of the third guide rail 45 and the movable body 51 reaches the end position of its movable range, this relative movement stops. When the movable body 51 is at the end position on the opening direction side of the movable range, that is, when the first roller 57 is in contact with the right end of the third guide rail 45, the door hanger 53, the support 54, and the connector 55 The connecting member 56 is movable integrally with the sliding door 30 in the opening/closing direction.

The door thickness changing mechanism 52 includes a moving mechanism 58, a rotating member 59, and a load converting mechanism 60. The door thickness changing mechanism 52 is arranged between the facing materials 31 on both sides.

The moving mechanism 58 moves the facing material 31 in the door thickness direction when a load in the door thickness direction is input to the facing material 31. Furthermore, when a load in the door thickness direction is input, the moving mechanism 58 converts the load in the door thickness direction into a rotational force and transmits it to the rotating member 59 . On the other hand, when a rotational force is input, the moving mechanism 58 converts this rotational force into a load in the door thickness direction and transmits it to the surface material 31. Four moving mechanisms 58 of this embodiment are arranged at intervals in the vertical direction and the opening/closing direction.

As shown in FIGS. 5A and 5B, the moving mechanism 58 includes a first rotating bar 61a and a second rotating bar 61b. The moving mechanism 58 is configured in a cross shape by intersecting the longitudinal centers of the first and second rotating bars 61a and 61b. At this intersection, the first and second rotating bars 61a and 61b are connected by the rotating member 59 through respective insertion holes (not shown).

The first rotating bar 61a is fixedly connected to the rotating member 59 so as to rotate integrally with the rotating member 59. A second roller 62 guided by a second guide rail 36a of the guide frame 36 is provided at one end of the first and second rotating bars 61a and 61b. A support shaft 63 that rotatably supports the first and second rotation bars 61a and 61b with respect to the guide frame 36 is provided at the other ends of the first and second rotation bars 61a and 61b. The first rotating bar 61a is provided on the upper side, and the second rotating bar 61b is provided on the lower side. The second rotating bar 61b is provided on the middle frame 42.

When a load in the door thickness direction is applied to one surface material 31, the load in the door thickness direction is transmitted to one end of the first and second rotating bars 61a and 61b via this surface material 31. As a result, the first and second rotating bars 61a and 61b rotate in opposite directions around the rotating member 59. Due to this rotational movement, a load in the door thickness direction is transmitted to the other surface material 31 via the other ends of the first and second rotating bars 61a and 61b. Further, due to the force in the X direction of this rotational movement, one ends of the first and second rotating bars 61a and 61b move in the X direction along the second guide rail 36a via the second roller 62. On the other hand, the other ends of the first and second rotating bars 61a and 61b are supported by the support shaft 63, and therefore do not move in the X direction. As a result, the angle between the first rotary bar 61a and the second guide rail 36a changes, and the surface material 31 on both sides moves in the door thickness direction.

The rotating member 59 is a rod-shaped member, and transmits the rotational force input from one of the moving mechanism 58 and the load converting mechanism 60 to the other. The upper end of the rotating member 59 is connected to a first link member 64a and a second link member 64b of the load conversion mechanism 60, which will be described later. The rotating member 59 is connected to the back side member 32 through insertion holes (not shown) formed in the upper frame 39 and middle frame 42 of the back side member 32, respectively.

The load conversion mechanism 60 converts the rotational force input from the rotating member 59 into a load in the opening/closing direction and transmits it to the movable body 51. Furthermore, the load conversion mechanism 60 converts the load in the opening/closing direction inputted from the moving body 51 into rotational force and transmits it to the rotation member 59 . One end of the load conversion mechanism 60 on the closing direction side is connected to the rotating member 59 , and the other end of the load conversion mechanism 60 is connected to the connection member 56 via a connection shaft 65 . Since the load conversion mechanisms 60 on both the left and right sides are connected to both ends of the connection member 56, when a load in the door thickness direction is applied to the surface material 31, the load conversion mechanisms 60 on both the left and right sides perform the same operation.

As shown in FIGS. 7(a) and 7(b), the load conversion mechanism 60 is a link mechanism having first to fourth link members 64a to 64d in the form of elongated plates. The first to fourth link members 64a to 64d have the same length dimension. The load conversion mechanism 60 has a rectangular shape with each of the first to fourth link members 64a to 64d as one side. The first link member 64a and the fourth link member 64d operate while maintaining a mutually parallel state, and the second link member 64b and the third link member 64c operate while maintaining a mutually parallel state.

One end of the first link member 64a and one end of the second link member 64b are connected by a rotating member 59. The other end of the first link member 64a and one end of the third link member 64c are connected by a pin 66a. The other end of the second link member 64b and one end of the fourth link member 64d are connected by a pin 66b. The other end of the third link member 64c and one end of the fourth link member 64d are connected by a connecting shaft 65.

The first link member 64a is fixedly connected to the rotating member 59 so as to rotate together with the rotating member 59. Therefore, when one of the rotating member 59 and the first link member 64a rotates, the rotational motion is transmitted to the other.

Connection mechanism 50 includes first and second support members 67 and 68 that support moving mechanism 58. The first support member 67 is provided at a portion of the rotating member 59 directly below the middle frame 42 . The second support member 68 is provided in the rotating member 59 directly above the first rotating bar 61a. The first and second support members 67 and 68 sandwich and support the rotating member 59 via the middle frame 42, thereby suppressing vertical movement of the rotating member 59 and, by extension, the moving mechanism 58.

(Operation of moving mechanism) As shown in FIGS. 5(a) and 5(b), the distance between the surface materials 31 on both sides is L1, and the angle between the first rotating bar 61a and the second guide rail 36a is Let it be θ1. As shown in FIG. 5(a), in the fully closed state, the distance L1 is the largest and the angle θ1 is the smallest.

The operation of the moving mechanism 58 when shifting from the fully closed state shown in FIG. 5(a) to the partially closed state shown in FIG. 5(b) will be described. In the fully closed state, for example, when a user pushes one surface material 31 inward in the door thickness direction, a load on the inside in the door thickness direction is input to one surface material 31. At this time, this load is transmitted to the first and second rotating bars 61a and 61b via this surface material 31. As a result, the first and second rotating bars 61a and 61b rotate clockwise and counterclockwise about the rotating member 59, respectively. Due to these rotational movements, the load on the inside in the door thickness direction is transmitted to the other surface material 31 via the other ends of the first and second rotating bars 61a and 61b. As a result, as shown in FIG. 5(a), force is applied to the surface materials 31 on both sides in a direction toward each other via both ends of the first and second rotating bars 61a and 61b. As a result, the second roller 62 moves in the closing direction along the second guide rail 36a so that the angle θ1 becomes larger, and the surface materials 31 on both sides move closer to each other. Therefore, as a result of the distance L1 becoming smaller, the thickness of the sliding door 30 becomes smaller. After that, the sliding door 30 becomes partially closed and stops rotating. As shown in FIG. 5(b), in the partially closed state, the angle θ1 is the largest and the distance L1 is the smallest.

The operation of the moving mechanism 58 when shifting from the partially closed state shown in FIG. 6(a) to the fully closed state shown in FIG. 6(b) will be described. In the partially closed state, for example, when a user grasps the grip portion 38 and pulls one surface material 31 outward in the door thickness direction, a load on the outside in the door thickness direction is input to one surface material 31. At this time, this load is transmitted to the first and second rotating bars 61a and 61b via this surface material 31. As a result, the first and second rotating bars 61a and 61b rotate counterclockwise and clockwise about the rotating member 59, respectively. Due to these rotational movements, the load on the outside in the door thickness direction is transmitted to the other surface material 31 via the other ends of the first and second rotating bars 61a and 61b. As a result, as shown in FIG. 6(a), force is applied to the surface materials 31 on both sides in the direction of separating them from each other via both ends of the first and second rotating bars 61a and 61b. As a result, the second roller 62 moves in the opening direction along the second guide rail 36a so that the angle θ1 increases, and the surface materials 31 on both sides move away from each other. Therefore, as a result of the distance L1 increasing, the thickness of the sliding door 30 increases. After that, the sliding door 30 becomes fully closed and stops rotating. As shown in FIG. 6(b), in the fully closed state, the angle θ2 is the smallest and the distance L1 is the largest.

Note that the rotational motion of the first rotating bar 61a is transmitted to the rotating member 59. As a result, the rotating member 59 rotates in the same direction as the rotation direction of the first rotating bar 61a. Therefore, when transitioning from the fully closed state to the partially closed state, both the first rotating bar 61a and the rotating member 59 rotate clockwise. On the other hand, when transitioning from the fully closed state to the partially closed state, both the first rotating bar 61a and the rotating member 59 rotate counterclockwise.

(Operation of load conversion mechanism) As shown in FIGS. 7(a) and 7(b), the distance between the connecting shaft 65 and the rotating member 59 is L2, and the angle formed by the first link member 64a and the X-direction axis Let be θ2. As shown in FIG. 7(a), in the fully closed state, the distance L2 is the smallest and the angle θ2 is the largest.

The operation of the load conversion mechanism 60 when shifting from the fully closed state shown in FIG. 7(a) to the partially closed state shown in FIG. 7(b) will be described. When a load on the inner side in the door thickness direction is input to one of the surface members 31 in the fully closed state, the first rotating bar 61a rotates clockwise and the rotating member 59 rotates clockwise, as described above. Since the rotating member 59 is fixedly connected to the first link member 64a, the first link member 64a rotates clockwise together with the rotating member 59. As a result, the angle θ2 becomes smaller and the distance L2 becomes larger. Along with this, the connecting shaft 65 moves in the opening direction, and therefore the connecting member 56 moves in the opening direction. After that, the sliding door device 100 enters a partially closed state and stops rotating. As shown in FIG. 7(b), in the partially closed state, the distance L2 is the largest and the angle θ2 is the smallest.

The operation of the load conversion mechanism 60 when transitioning from the partially closed state shown in FIG. 8(a) to the fully closed state shown in FIG. 8(b) will be described. When a load on the outside in the door thickness direction is input to one of the surface members 31 in the partially closed state, as described above, the first rotating bar 61a rotates counterclockwise and the rotating member 59 rotates counterclockwise. do. As a result, the first link member 64a rotates counterclockwise together with the rotating member 59. As a result, the angle θ2 becomes larger and the distance L2 becomes smaller. Along with this, the connecting shaft 65 moves in the closing direction, and therefore the connecting member 56 moves in the closing direction. After that, the sliding door device 100 enters a partially closed state and stops rotating. As shown in FIG. 8(b), in the partially closed state, the distance L2 is the smallest and the angle θ2 is the largest.

(Operation of sliding door) The operation of the sliding door 30 from the fully closed state to the fully open state and again to the fully closed state will be explained.

Referring to FIGS. 9 and 10(a), in the fully closed state, the back side member 32 is held by the catcher 16, and the first roller 57 is in contact with the left end of the third guide rail 45. At this time, as shown in FIG. 10(a), the sliding door 30 has a thickness such that it is flush with the building wall surfaces 1 on both sides in the door thickness direction. Here, "being flush" means that the surface material 31 of the sliding door 30 on both sides in the door thickness direction and the building wall surface 1 are placed flush with each other.

In the fully closed state, when a load is input to the inside of the door in the thickness direction by the user pushing the surface material 31 inward in the door thickness direction, a load is applied to the movement mechanism 58 via the surface material 31. This load on the inside in the door thickness direction is transmitted. As a result, the first and second rotating bars 61a and 61b rotate clockwise and counterclockwise about the rotating member 59, respectively. Therefore, forces are applied to the surface materials 31 on both sides in a direction toward each other via the first and second rotating bars 61a and 61b. As a result, the second roller 62 moves in the closing direction along the second guide rail 36a, and the surface materials 31 on both sides move toward each other. As a result, the door thickness becomes smaller.

Further, the rotating member 59 rotates clockwise together with the first rotating bar 61a. This rotational movement is transmitted to the load conversion mechanism 60. As a result, in the load conversion mechanism 60, the first link member 64a rotates clockwise together with the rotating member 59. Along with this, the connecting shaft 65 moves in the opening direction, so the connecting member 56 moves in the opening direction, and the first roller 57 moves in the opening direction along the third guide rail 45. On the other hand, since the back side member 32 is held by the catcher 16, the sliding door 30 does not move. As a result, the moving body 51 moves relative to the sliding door 30 in the opening direction.

Thereafter, the first roller 57 contacts the right end of the third guide rail 45. As a result, the relative movement stops, the door thickness becomes the smallest, and the sliding door device 100 enters a partially closed state as shown in FIGS. 10(b) and 12.

After that, for example, the user grasps the grip portion 38 and inputs a load to the sliding door 30 in the opening direction. When the force input to the sliding door 30 becomes larger than the force with which the catcher 16 holds the back side member 32, the hold on the back side member 32 by the catcher 16 is released. Thereafter, as the user continues to apply a load to the sliding door 30 in the opening/closing direction, the movable body 51 and the sliding door 30 move integrally in the opening direction, as shown in FIG. 13 . Note that in FIG. 13, the partition frame 15 is omitted for simplification. Thereafter, as shown in FIGS. 10(c) and 14, the sliding door device 100 becomes fully open.

In the fully open state, for example, when a user grasps the grip portion 38 and pulls out the sliding door 30 in the closing direction, a load is input to the sliding door 30 in the closing direction. This load is transmitted from the surface material 31 to the back side member 32 via the moving mechanism 58. As a result, as shown in FIG. 15, the moving body 51 and the sliding door 30 move integrally in the closing direction. Thereafter, the back side member 32 is held in contact with the catcher 16, and as shown in FIGS. 11(b) and 16, the sliding door device 100 enters a partially closed state.

In the partially closed state, for example, when a user grasps the grip portion 38 and pulls out the surface material 31 outward in the door thickness direction, a load on the outside in the door thickness direction is input to the surface material 31. This load on the outside in the door thickness direction is transmitted to the moving mechanism 58 via the surface material 31. As a result, the first and second rotating bars 61a and 61b rotate counterclockwise and clockwise about the rotating member 59, respectively. Therefore, force is applied to the surface materials 31 on both sides in a direction in which they move away from each other via the first and second rotating bars 61a and 61b. As a result, the second roller 62 moves in the opening direction along the second guide rail 36a, and the surface materials 31 on both sides move away from each other. As a result, the door thickness increases.

Further, the rotating member 59 rotates counterclockwise together with the first rotating bar 61a. This rotational movement is transmitted to the load conversion mechanism 60. As a result, in the load conversion mechanism 60, the first link member 64a rotates counterclockwise together with the rotating member 59. Along with this, the connecting shaft 65 moves in the closing direction, so the connecting member 56 moves in the closing direction, and the first roller 57 moves in the closing direction along the third guide rail 45. On the other hand, since the back side member 32 is held by the catcher 16, the sliding door 30 does not move. As a result, the movable body 51 moves relative to the sliding door 30 in the closing direction.

Thereafter, the first roller 57 contacts the left end of the third guide rail 45. As a result, the above-mentioned relative movement stops, the door thickness becomes maximum, and the sliding door device 100 becomes fully closed as shown in FIG. 11(c).

(Operations and Effects) The sliding door device 100 of this embodiment includes a sliding door 30 whose thickness can be changed. Thereby, in the fully open state, the sliding door 30 is accommodated in the door pocket 4, and the building wall surface 1 and the sliding door 30 are flush with each other. Therefore, it is possible to realize a building opening 2 that has a neat and beautiful appearance.

By the way, as one technique for realizing this, there is a configuration described in Patent Document 1. In the configuration described in Patent Document 1, the thickness of the door is reduced by utilizing the guiding action of the inclined guide surface. In particular, in the sliding door device described in Patent Document 1, by bringing the sliding door into contact with the inclined guide surface during the opening operation of the sliding door, a load that reduces the door thickness is inputted to the sliding door from the inclined guide surface. As a result, the door thickness becomes smaller.

However, in this configuration, it is necessary to design the sliding door, the inclined guide surface, the guide rail of the sliding door, etc. so as to apply an input load in the door thickness direction to the sliding door during the opening operation of the sliding door. Therefore, in the sliding door device described in Patent Document 1, the sliding door, the inclined guide surface, the guide rail, etc. are likely to be subject to structural restrictions. Therefore, there was a problem that the degree of freedom in designing the sliding door was small.

The sliding door device 100 of this embodiment includes a sliding door 30 including a back side member 32 connected to the frame 10 so as to be able to transmit a load in the door thickness direction, and a surface material 31 when a load in the door thickness direction is input. and a connection mechanism 50 that connects the surface material 31 to the back side member 32 so as to be movable in the door thickness direction. According to this configuration, even if a load in the door thickness direction is input to the surface material 31, this load in the door thickness direction is transmitted to the frame 10 via the back side member 32. Therefore, movement of the back side member 31 in the door thickness direction is suppressed. On the other hand, since the surface material 31 is connected to the back side member 32 via the connection mechanism 50 so as to be movable in the door thickness direction, the surface material 31 can freely move in the door thickness direction. Therefore, even in the fully closed state, if a load is input in the door thickness direction, the door thickness can be changed, thereby reducing the need to apply an input load to the sliding door 30 during the sliding door opening operation to change the door thickness. . Therefore, for example, unlike the sliding door device described in Patent Document 1, there is no need to provide a chamfered portion on the sliding door and provide an inclined guide surface near the door bag opening on which the chamfered portion comes into contact during the opening operation. Therefore, the sliding door device 100 of this embodiment is less subject to structural restrictions. As a result, the degree of freedom in designing the sliding door increases.

The facing material 31 is provided on both sides of the back side member 32 in the door thickness direction, and the connection mechanism 50 adjusts the facing material to the door thickness when a load in the door thickness direction is input to one of the facing materials 31 on both sides. move in the direction. According to this configuration, the door thickness can be changed simply by inputting a load in the door thickness direction to one surface material 31.

The connection mechanism 50 moves both of the facing materials 31 on both sides in opposite directions when a load in the door thickness direction is input to one of the facing materials 31 on both sides. According to this configuration, simply by inputting a load in the door thickness direction to one of the facing members 31, the facing members 31 on both sides move in opposite directions, thereby achieving a door thickness changing operation that has a uniform appearance.

The facing material 31 is supported by the back side member 32 so as to be movable in the door thickness direction via the connecting mechanism 50 . According to this configuration, it is not necessary to provide, for example, a roller or the like below the surface material 31 to support the surface material 31 for movement in the door thickness direction. As a result, the surface material 31 can be easily moved in the door thickness direction relative to the floor or the like.

(Modification) Although a configuration has been shown in which the sliding door 30 is directly closed by grasping the grip portion 38 with the user's hand when the sliding door 30 is in the fully open state, the present invention is not limited to this. For example, a configuration in which a string-like member connected to the movable body 51 is extended from the intermediate horizontal frame 14 may be used. Thereby, for example, when the user pulls this string-like member in the closing direction when the movable body 51 is in the fully open state, it is possible to input a load in the closing direction to the movable body 51. As a result, the load in the closing direction is transmitted to the sliding door 30 via the moving body 51, so the sliding door 30 moves in the closing direction.

Although an example has been shown in which a load on the outside in the door thickness direction is inputted to the surface material 31 using the grip portion 38 when the sliding door device 100 transitions from the partially closed state to the fully closed state, the present invention is not limited to this. For example, a configuration in which the string-like member is connected to the movable body 51 may be used. Thereby, it becomes possible to input a load in the closing direction to the moving body 51. As a result, as will be described later, the sliding door device 100 can be moved from the partially closed state to the fully closed state, thereby increasing the door thickness. The reason for this will be explained below.

When a load in the closing direction is input to the movable body 51 in the partially closed state, the first roller 57 moves in the closing direction along the third guide rail 45 due to the input load in the closing direction, so that the movable body 51 Move in the closing direction. On the other hand, since the back side member 32 is held by the catcher 16, the sliding door 30 does not move. As a result, the movable body 51 moves relative to the sliding door 30 in the closing direction. Due to this relative movement in the closing direction, in the load conversion mechanism 60, the distance L2 becomes smaller and the angle θ2 becomes larger. As a result, the rotating member 59 rotates counterclockwise. This counterclockwise rotational movement is transmitted to the moving mechanism 58 via the rotating member 59.

The first rotating bar 61a of the moving mechanism 58 receives this counterclockwise rotation and rotates counterclockwise about the rotating member 59. As a result, force is applied to the surface materials 31 on both sides in the direction of separating them from each other. As a result, the surface materials 31 on both sides move away from each other, so the door thickness increases. Thereafter, when the first roller 57 comes into contact with the left end of the third guide rail 45, the relative movement stops and the sliding door device 100 enters the fully closed state.

From the above, even when a load in the closing direction is input to the movable body 51 using the string-like member, the sliding door device 100 can be moved from the partially closed state to the fully closed state and the door thickness can be increased. is understood.

When using the string-like member, a pulley or the like may be provided between the string-like member and the movable body 51 to convert an input load into a load in the opening/closing direction. As a result, even if it is difficult to input a load in the closing direction to the movable body 51 in the partially closed state, the load applied to the string member is converted into a load in the closing direction by this pulley and is input to the movable body 51. Ru. Therefore, it becomes easier to input a load in the closing direction to the moving body 51.

Note that the configuration for inputting a load in the opening/closing direction to the moving body 51 is not limited to the above string-like member. For example, an electric drive device having a motor or the like for moving the movable body 51 in the opening/closing direction may be used. Here, in a configuration in which a load in the opening/closing direction is input to the movable body 51 using this electric drive device, for example, if a power outage occurs in the fully closed state, the electric drive device cannot operate and the movable body 51 moves in the opening/closing direction. become unable. Furthermore, since the door thickness is large in the fully closed state, even if the sliding door 30 is moved in the opening/closing direction by applying a load in the opening/closing direction to the sliding door 30 by hand, as shown in FIG. collides with the partition frames 15 on both sides. Therefore, in the configuration using the electric drive device described above, the sliding door 30 cannot be opened or closed during a power outage. On the other hand, in this embodiment, even if there is a power outage in the fully closed state, if a load is input to the surface material 31 on the inside in the door thickness direction, the door thickness will be reduced and the sliding door 30 will be able to move in the opening/closing direction. . As a result, even in the event of a power outage, the sliding door 30 can be easily opened and closed.

Although an example in which the catcher 16 is used is shown, the present invention is not limited to this, and for example, the sliding door 30 may be held by the user's hand when transitioning from the fully closed state to the partially closed state. Moreover, the catcher 16 may be provided at any location as long as it can hold the sliding door 30, for example, it may be provided on the intermediate horizontal frame 14. The catcher 16 may be, for example, a roller, a pincher, or the like.

Although the supports 54 are provided on both left and right sides of the door hanger 53, only one support 54 may be provided on the door hanger 53. Alternatively, three or more supports 54 may be provided on the door hanger 53.

The back side member 32 may be made of non-metal. In this case, a metal catcher receiving member may be provided on the back side member 32 so as to come into contact with the catcher 16 in the partially closed state. Further, the back side member 32 does not need to have the middle frame 42.

Regarding the moving mechanism 58, an example using the first and second rotating bars 61a and 61b has been described, but it is not limited to this, and a rack and pinion mechanism that converts the linear movement of the connecting member 56 into rotational movement, etc. A gear mechanism may also be utilized.

Regarding the load conversion mechanism 60, an example using the first to fourth link members 64a to 64d has been described, but the present invention is not limited to this. A zip chain or the like may be used, which becomes a single columnar shape by engaging with the surface material 31 and can push and pull the surface material 31.

The moving mechanism 58 does not need to have the second rotation bar 61b.

Although two sets of the moving mechanism 58, the rotating member 59, and the load converting mechanism 60 are provided on both left and right sides of the connecting member 56, only one set of these may be provided on the connecting member 56. Alternatively, the connecting member 56 may be provided with three or more sets of these.

The moving mechanisms 58 are provided on both upper and lower sides of the rotating member 59, but only one moving mechanism 58 may be provided on the rotating member 59. Alternatively, the rotating member 59 may be provided with three or more moving mechanisms 58.

Although the door hanger 53, the support 54, the connector 55, and the connection member 56 are each integrally connected as separate members, they may be configured as one member.
