Description

This disclosure relates to a sliding door structure.

Conventionally, there is known a sliding door structure that allows the thickness of the sliding door to be changed so that it can be accommodated within the door case when the thickness of the sliding door is greater than the thickness of the door case that houses the sliding door (for example, Patent Document 1).

JP 2018-066178 A

Patent Document 1 describes a structure that allows the distance between two door panels in the thickness direction to be adjusted, and includes a guide section that guides the two door panels to move closer together when the sliding door is moved from a closed state to an open state. A spring is placed between the two door panels to urge the door panels together in a direction that increases the thickness.

In the structure of Patent Document 1, the door panels are always biased in a direction that increases the thickness of the sliding door. It is desirable to smoothly adjust the biasing force applied to the door panels when opening and closing the sliding door.

This disclosure has been made to solve the above problems, and aims to provide a sliding door structure with a highly safe sliding door whose thickness can be changed.

According to one aspect of the present disclosure, a sliding door structure includes a sliding door that opens and closes an opening provided in a door frame, the sliding door includes a sliding door body that can move in a direction that opens and closes the opening, and at least one door panel that is supported by the sliding door body and can move in the door thickness direction, and the sliding door structure further includes a door panel movement mechanism that moves the door leading side of the door panel outward in the door thickness direction in response to the movement of the sliding door body in the closing direction, and then moves the door trailing side of the door panel outward in the door thickness direction.

The following describes an embodiment of the present disclosure. In the embodiment, a detailed description will be given using an example in which the sliding door structure is provided on a fixed wall of a living space. The framework to which the sliding door structure is attached may be a framework such as a movable wall other than a fixed wall.

In the following embodiments, directions may be described using a three-dimensional Cartesian coordinate system consisting of an X-axis, a Y-axis, and a Z-axis. The X-axis extends along the opening and closing direction of the sliding door. The Y-axis is perpendicular to the X-axis in the horizontal plane. The Z-axis extends along the vertical direction.

Figure 1 is a partial perspective view of a living space to which a sliding door structure is applied. The sliding door structure 10 is equipped with a sliding door 16 that opens and closes an opening 14 that connects spaces partitioned by a fixed wall 12. The sliding door 16 is movable between two positions: a closed position in which the opening 14 is closed, and an open position in which the opening 14 is open. In the closed position, the sliding door 16 is almost flush with the surface of the fixed wall 12. This improves the aesthetic appearance of the sliding door structure 10. In the open position, the sliding door 16 is accommodated in a space (door pocket S, described later) provided inside the fixed wall 12.

A transom 18 is provided above the opening 14. The transom 18 houses a drive unit (not shown in FIG. 1) such as a motor, pulley, and timing belt for driving the sliding door 16.

The sliding door structure 10 includes a signal output unit 20 arranged on the fixed wall 12. The signal output unit 20 outputs a drive signal for the sliding door 16 in response to an operation by an operator. The signal output unit 20 is configured with a contact or non-contact type operation switch. In this case, the operator operates the operation switch, and the signal output unit 20 outputs a drive signal. The drive unit drives the sliding door 16 in response to the drive signal. A sensor may be provided on the blind 18 to detect whether a person or the like is present within a specified range in front of the sliding door 16.

2 and 3 are cross-sectional views of the sliding door structure, and FIG. 4 is a perspective view of the sliding door body. Specifically, FIG. 2 shows the sliding door 16 in the closed position, and FIG. 3 shows the sliding door 16 in the open position. As shown in FIGS. 2 and 3, the door thickness (thickness along the Y-axis direction) of the sliding door 16 in the closed position is thinner than the door thickness of the sliding door 16 in the open position. The thickness of the sliding door 16 in the open position is slightly thinner than the thickness (thickness along the Y-axis direction) of the door pocket S. The thickness of the sliding door 16 in the closed position is almost the same as the thickness of the opening 14 closed by the sliding door 16 (i.e., the distance between the two surfaces of the fixed wall 12 facing opposite sides). As a result, the sliding door 16 forms a flat surface with the surface of the fixed wall 12 in the open position. The door thickness of the sliding door 16 becomes thicker as it moves from the open position to the closed position. On the other hand, the door thickness of the sliding door 16 becomes thinner as it moves from the closed position to the open position.

The sliding door 16 comprises a sliding door body 22, two door panels 24, a first moving part 26, and a second moving part 28. The sliding door body 22 is formed of a frame body. The sliding door body 22 holds the other components of the sliding door 16 (door panels 24, first moving part 26, second moving part 28, etc.). The sliding door body 22 is mechanically connected to a drive unit such as the motor described above. Therefore, the driving force from the drive unit is input to the sliding door body 22, and the entire sliding door 16 is driven by driving the sliding door body 22. By making the sliding door body 22 a frame body, the sliding door body 22 can be made lighter. In addition, by making the sliding door body 22 a frame body, parts such as the first moving part 26 and the second moving part 28 can be built into the opening of the frame body, and the door thickness of the sliding door 16 can be made thinner.

The two door panels 24 are arranged to sandwich the sliding door body 22 along the Y axis. Each door panel 24 is composed of a plate-shaped member having a first main surface 30 facing outward in the door thickness direction of the sliding door 16 and a second main surface 32 facing inward in the door thickness direction. The first main surface 30 may be decorated with the same decoration as the surface of the fixed wall 12, for example. This improves the unity of the sliding door 16 and the fixed wall 12 when the sliding door 16 is closed. The door panel 24 is suspended from the sliding door body 22. The door panel 24 moves outward or inward in the door thickness direction relative to the sliding door body 22 in response to the movement of the sliding door 16. The door thickness of the sliding door 16 changes as the position of the door panel 24 relative to the sliding door body 22 changes. In this embodiment, an example in which the two door panels 24 each move along the Y axis relative to the sliding door body 22 will be described. However, one door panel 24 may be fixed to the sliding door body 22, and only the other door panel 24 may be movable relative to the sliding door body 22.

The two door panels 24 and the sliding door body 22 have approximately the same length in the width direction (X-axis direction). When the sliding door 16 is in the closed position, the ends (±X side ends) of the two door panels 24 and the sliding door body 22 are aligned in a substantially straight line. On the other hand, when the sliding door 16 is in the open position, the leading ends of the two door panels 24 are located on the +X side of the sliding door body 22.

The first moving unit 26 and the second moving unit 28 form part of a sliding door movement mechanism that moves the door panel 24 relative to the sliding door body 22 in accordance with the movement of the sliding door 16. The first moving unit 26 is positioned closer to the tail end than the center of the width direction (X-axis direction) of the sliding door 16, and the second moving unit 28 is positioned closer to the tip end than the center of the width direction (X-axis direction) of the sliding door 16. The first moving unit 26 and the second moving unit 28 change the position of the door panel 24 relative to the sliding door body 22 independently of each other.

The first moving part 26 comprises a pair of rear arms 34, 36 (corresponding to "closing link members") and a pair of slide arms 38, 40. The second moving part 28 comprises a pair of front arms 42, 44 (corresponding to "opening link members") and a linear guide 46. A pair of rear arms 34, 36 and slide arms 38, 40 are provided above and below the sliding door 16. A pair of front arms 42, 44 are also provided above and below the sliding door 16. This allows the thickness of the sliding door 16 to be changed simultaneously in the vertical direction.

The rear arms 34, 36 each have an end on the trailing edge and an end on the leading edge. The trailing edge ends of the rear arms 34, 36 are each fixed to the sliding door body 22 and supported rotatably around axis Z1 extending in the Z-axis direction. The leading edge ends of the rear arms 34, 36 are each attached to the second main surfaces 32 of the two door panels 24. The leading edge ends of the rear arms 34, 36 are each attached rotatably around axes Z2, Z3 relative to the second main surfaces 32. The rear arms 34, 36 are each positioned on the +X side and -X side so as to sandwich the sliding door body 22 when viewed from above.

The slide arms 38, 40 each have an end on the trailing edge and an end on the leading edge. The trailing edge ends of the slide arms 38, 40 are attached to the second main surfaces 32 of the two door panels 24, respectively. More specifically, the trailing edge ends of the slide arms 38, 40 are attached to the door panel 24 so as to be rotatable around the same axes Z2, Z3 as the leading edge ends of the rear arms 34, 36. The leading edge ends of the slide arms 38, 40 can move along the X-axis relative to the sliding door body 22.

Figure 5 is an enlarged perspective view showing a part of the sliding door body. As shown in Figure 5, specifically, a gear 100 and a gear damper 102 are provided at the leading ends of the sliding arms 38, 40. The leading ends of the sliding arms 38, 40 are attached to the shaft of the gear 100. The combination of the gear 100 and the gear damper 102 applies a deceleration force to the movement of the sliding arms 38, 40 in the direction of closing (reducing the acute angle with the X-axis). The combination of the gear 100 and the gear damper 102 is slidably supported on a support member 104 extending in the X-axis direction of the sliding door body 22.

2 to 4, the rear end of the rear arm 34, 36 and the leading end of the slide arm 38, 40 are held so as to be relatively movable along the X-axis. The leading end of the rear arm 34, 36 and the trailing end of the slide arm 38, 40 are held so as to be rotatable around the same axes Z2 and Z3. With the first moving part 26 having such a configuration, as the distance between the trailing end of the rear arm 34, 36 and the leading end of the slide arm 38, 40 becomes shorter, the angle of the rear arm 34, 36 with respect to the X-axis (the acute angle between them) and the angle of the slide arm 38, 40 with respect to the X-axis (the acute angle between them) increase. As a result, the door panel 24 moves away from the sliding door body 22 near the first moving part 26. Conversely, as the distance between the trailing end of the rear arms 34, 36 and the leading end of the slide arms 38, 40 increases, the door panel 24 approaches the sliding door body 22 near the first moving part 26. In other words, by changing the distance between the trailing end of the rear arms 34, 36 and the leading end of the slide arms 38, 40, the distance between the door panel 24 and the sliding door body 22 near the first moving part 26 can be changed. It can also be said that the length of the first moving part 26 along the X-axis and the length of the first moving part 26 along the Y-axis are inversely proportional.

The second moving part 28 is positioned at a position offset toward the door edge along the X-axis relative to the first moving part 26. The ends of the front arms 42, 44 on the door tail side are fixed to each of the two door panels 24 and supported rotatably around axes Z4, Z5 extending in the Z-axis direction. The ends of the front arms 42, 44 on the door edge side are each supported by a linear guide 46. Specifically, the ends of the front arms 42, 44 on the door edge side are supported rotatably around axis Z6 passing through the linear guide 46.

The linear guide 46 is held slidably in the X-axis direction along a shaft 48 that is part of the sliding door body 22. When the linear guide 46 slides toward the tail end, the angle of the front arms 42, 44 with respect to the X-axis (the acute angle between them) increases. This causes the door panel 24 to move away from the sliding door body 22 near the second moving part 28. Conversely, when the linear guide 46 slides toward the tip end, the door panel 24 moves closer to the sliding door body 22 near the second moving part 28. In other words, by changing the position of the linear guide 46, the distance between the door panel 24 and the sliding door body 22 near the second moving part 28 can be changed. It can also be said that the length of the second moving part 28 along the X-axis and the length of the first moving part 26 along the Y-axis are inversely proportional.

A guide roller 50 (corresponding to a "protrusion") extends from the door panel 24 to the +Z side on the upper surface of the door leading side of each door panel 24. The guide roller 50 has a roller that rotates around the Z axis.

A connecting part 108 that is connected to the drive unit is provided on the upper part of the sliding door body 22. The connecting part 108 is fixed to the endless timing belt of the drive unit.

Figure 6 is a plan view showing the top of the opening. Figure 6 shows a view when viewed from the -Z side to the +Z side (i.e., when the top of the opening 14 is viewed from below). Two grooves 52 (corresponding to the "guide portion" and the "opening guide portion") are formed on the bottom surface of the opening 14 to guide the guide roller 50 when the door panel 24 moves. The guide roller 50 is inserted into the groove 52. The groove 52 changes the position of the guide roller 50 and the position of the end of the door panel 24 on the door tip side. The two grooves 52 extend parallel to the X axis from the end of the door tail side to the door tip side from the center of the width direction (X axis direction) of the sliding door 16. The two grooves 52 have a transition portion 54 that extends in a direction away from each other (in the XY plane) near the end on the door tip side. The two grooves 52 extend parallel to the X axis again on the door tip side from the transition portion 54. Alternatively, the groove 52 may be provided on the door panel 24 side, and the guide roller 50 may be provided on the underside of the opening 14.

Figure 7 is a block diagram showing the configuration of the sliding door structure. Figure 7 shows a functional block diagram in which each component of the sliding door structure is classified based on function. As shown in Figure 7, the sliding door structure 10 includes the sliding door 16, a signal output unit 20, a drive unit 60, and a door panel movement mechanism 62. The drive unit 60 corresponds to a frame drive unit, and includes a motor, a pulley, a timing belt, etc., and drives the sliding door 16 to open or close. The door panel movement mechanism 62 changes the thickness of the sliding door 16. In Figure 7, in order to make the explanation clearer, the drive unit 60 that drives the sliding door 16 and the door panel movement mechanism 62 that changes the thickness of the sliding door 16 are separated from each other from a functional standpoint. The door panel movement mechanism 62 includes a first moving unit 26, a second moving unit 28, and a guide mechanism 64 consisting of a groove 52 and a guide roller 50.

The operation of the sliding door structure will be explained below. At this time, the sliding door 16 is in a state in which it closes the opening 14. At this time, each door panel 24 is located away from the sliding door body 22, and the sliding door 16 is in a bulging state.

When an operator who wishes to open the sliding door 16 operates the signal output unit 20, the signal output unit 20 outputs an open drive signal to the drive unit 60. This causes the drive unit 60 to drive a motor and the like to start opening the sliding door 16. When the sliding door 16 starts to open, the first moving unit 26 mainly moves the door panel 24 closer to the sliding door body 22 at the door end side, thinning the thickness of the sliding door 16 at the door end side. Next, as the sliding door 16 continues to open, the door panel moving mechanism 62 moves the door panel 24 closer to the sliding door body 22 at the door end side, thinning the thickness of the sliding door 16 at the door end side. This causes the sliding door 16 to shrink to a thickness that can be stored in the door pocket S.

When the sliding door structure 10 determines that there is no person or the like around the sliding door 16, the sliding door structure 10 closes the sliding door 16. When closing the sliding door 16, the sliding door structure 10 drives the drive unit 60 to move the sliding door 16 along the X-axis. When the sliding door 16 moves a predetermined amount, the door panel 24 moves away from the sliding door body 22 mainly due to the action of the second moving unit 28, the guide roller 50, and the groove 52. As a result, the thickness of the sliding door 16 increases at the door end side, and the door end side of the sliding door 16 expands in the door thickness direction. When the sliding door 16 continues to close, the door panel 24 moves away from the sliding door body 22 mainly due to the action of the first moving unit 26 at the door end side. As a result, the thickness of the sliding door 16 increases at the door end side, and the door end side of the sliding door 16 expands in the door thickness direction. As a result, the sliding door 16 forms a flat surface with the surface of the fixed wall 12.

When the sliding door 16 is opened, the sliding door structure 10 drives the drive unit 60 to move the sliding door 16 along the X-axis. When the sliding door 16 has moved a predetermined amount, the door panel 24 approaches the sliding door body 22, mainly due to the action of the first moving unit 26. This reduces the thickness of the sliding door 16 on the door end side, and the door end side of the sliding door 16 shrinks in the door thickness direction. When the sliding door 16 continues to close, the door panel 24 approaches the sliding door body 22 on the door end side, mainly due to the action of the second moving unit 28. This reduces the thickness of the sliding door 16 on the door end side, and the door end side of the sliding door 16 shrinks in the door thickness direction. This makes the sliding door 16 thick enough to be stored in the door pocket S.

In the above description, the expression "mainly acts" also includes the fact that the relevant component mainly acts, and other components also act secondarily. For example, when the sliding door 16 is moved from the closed position to the open position, the first moving part 26 mainly thins the thickness of the sliding door 16, but other components such as the front arms 42, 44 and the guide roller 50 also act secondarily to maintain the position of the door panel 24 relative to the sliding door body 22 as the thickness of the sliding door 16 thins.

The operation of the sliding door structure 10 will be described in more detail below. Figures 8 to 10 are horizontal cross-sectional views showing a series of operations when the sliding door is moved from the closed position to the open position. For ease of explanation, in Figures 8 to 10, the cross section of the sliding door 16, the groove 52, and the guide roller 50 are shown on the same plane.

As shown in Figure 8, when the sliding door 16 is in the closed position, the leading end of the sliding door 16 is in contact with the vertical bar 66. The rear arms 34, 36, slide arms 38, 40 and front arms 42, 44 are in the most open state (i.e., the state in which the acute angle with the X-axis is the largest). In this state, the door panel 24 is held parallel to the X-axis at a position away from the sliding door main body 22. In this state, when the drive unit 60 (see Figure 7) is driven to drive the sliding door main body 22 to the -X side, it transitions to the state shown in Figure 9.

As shown in FIG. 9, when the sliding door 16 is driven to the -X side, the sliding door body 22 is pulled to the -X side, and the rear end of the rear arms 34, 36 is pulled to the -X side. The leading end of the slide arms 38, 40 and the linear guide 46 are not fixed to the sliding door body 22. Therefore, immediately after the sliding door body 22 is driven, the leading end of the slide arms 38, 40 and the linear guide 46 tend to remain in their current positions. When the trailing end of the rear arms 34, 36 is pulled to the -X side, a pulling force acts in the axial direction of the rear arms 34, 36. As a result, the trailing end of the rear arms 34, 36 rotates around the axis Z1 extending in the Z-axis direction, while the leading end of the rear arms 34, 36 rotates around the axes Z2, Z3, generating a force F1 that moves the door panel 24 closer to the sliding door body 22. The force F1 acts in a direction that pulls the door panel 24 into the door pocket S. As a result, the ends of the slide arms 38, 40 on the door leading side slide along the X-axis toward the door leading side, and the angle (acute angle) between the slide arms 38, 40 and the X-axis becomes smaller. In other words, the first moving part 26 extends in the X-axis direction and contracts in the Y-axis direction. At this time, the distance between the two door panels 24 on the door leading side remains almost unchanged. In this state, when the drive part 60 (see FIG. 7) is driven to drive the sliding door main body 22 to the -X side, it transitions to the state shown in FIG. 10.

When the drive unit 60 (see FIG. 7) continues to be driven, as shown in FIG. 10, the sliding door body 22 is pulled to the -X side, and the door panels 24 are also pulled to the -X side. As the door panels 24 move, the guide rollers 50 also move along the grooves 52. When the guide rollers 50 enter the transition section 54, the two door panels 24 move in a direction approaching each other. As a result, the door panels 24 move closer to the sliding door body 22 on the door tip side. This makes the sliding door 16 thick enough to be stored in the door pocket S.

After that, by continuing to drive the drive unit 60, the sliding door 16 is stored in the door pocket S as shown in FIG. 11.

Figures 12 and 13 are horizontal cross-sectional views showing a series of operations when moving the sliding door from the open position to the closed position. For ease of explanation, in Figures 12 and 13, the cross section of the sliding door 16, the groove 52, and the guide roller 50 are shown on the same plane.

As shown in FIG. 11, when the sliding door 16 is in the open position, the rear arms 34, 36, slide arms 38, 40 and front arms 42, 44 are in the most closed state (i.e., the acute angle with the X-axis is the smallest). In this state, the door panel 24 is held parallel to the X-axis in a position close to the sliding door main body 22. In this state, when the driving unit 60 (see FIG. 7) is driven to drive the sliding door main body 22 to the +X side, the door panel 24 moves together with the sliding door main body 22 as the sliding door main body 22 moves to the +X side.

As shown in FIG. 12, when the guide roller 50 enters the transition section 54, the two door panels 24 begin to move away from each other. This increases the door thickness at the door tip side of the sliding door 16. At this time, the door tip side ends of the front arms 42, 44 rotate around the axis Z6, and the acute angle that the front arms 42, 44 make with respect to the X axis increases. As a result, the linear guide 46 moves toward the door tail side relative to the sliding door main body 22. The door tip side ends of the two door panels 24 are located on the +X side relative to the sliding door main body 22. Therefore, when the sliding door 16 is moved to the +X side, the door tip side ends of the door panels 24 contact the vertical bar 66 before the door tip side ends of the sliding door main body 22. By continuing to drive the sliding door main body 22 in the +X direction even after the door tip side ends of the door panels 24 contact the vertical bar 66, the door panels 24 do not move along the +X direction, but the sliding door main body 22 moves in the +X direction. In other words, the sliding door body 22 moves independently of the door panel 24. As a result, while the position of the leading end of the rear arms 34, 36 in the X-axis direction is fixed, the trailing end of the rear arms 34, 36 moves in the +X direction. This increases the acute angle that the rear arms 34, 36 make with respect to the X-axis, and a force F2 acts on the door panel 24 in the direction of opening the door panel 24. This increases the door thickness on the trailing end of the sliding door 16. The drive unit 60 stops when the sliding door body 22 comes into contact with the vertical bar 66. This makes the door thickness of the sliding door 16 the same on the trailing end and leading end, as shown in FIG. 13.

In this way, with the sliding door structure 10, the thickness of the sliding door 16 can be changed independently at the door front and door rear ends in conjunction with the movement of the sliding door 16 along the X-axis. In this way, the thickness of the sliding door 16 can be smoothly adjusted without using a spring or other biasing member, ensuring high safety. In addition, because it can be changed, the door panel 16 can be prevented from suddenly popping out. Furthermore, it can be prevented that the door panel 24 pops out and comes into contact with the vertical bars, accelerating the sliding door 16. This enhances safety.

In addition, by using the second moving part 28, which has front arms 42, 44, one end of which is fixed to the door panel 24 and the other end of which is slidably held, the sliding door 16 can be expanded in response to the sliding door 16 when driving the sliding door 16 to close without using a biasing means such as a spring. This improves safety.

In addition, by using the groove 52 and the guide roller 50 as a guide portion, the sliding door 16 can be reliably expanded when the sliding door 16 is driven to close.

In addition, the driving unit 60 is driven in response to a driving signal from the signal output unit 20, thereby driving the sliding door 16, so that the sliding door structure 10 can also be used as an automatic door.

In addition, as the sliding door body 22 moves in the opening direction, the door panel 24 is moved closer to the sliding door body 22, thereby changing the thickness of the sliding door 16 to a thickness that can be accommodated in the door pocket S.

In this case, by using the first drive unit 26 equipped with rear arms 34, 36, one end of which is fixed to the door panel 24 and the other end of which is slidably held, the sliding door 16 can be compressed in accordance with the sliding door 16 when driving the sliding door 16 to open without using a biasing means such as a spring. This improves safety.

Below, a modified example of the embodiment will be described. FIG. 14 is a horizontal cross-sectional view of a sliding door structure according to a modified example. As shown in FIG. 14, an inclined surface 200 may be provided at the entrance to the door pocket S. The inclined surface 200 is formed on the inner surface in the door thickness direction of the vertical bar on the door tail side (-X side). The inclined surface 200 has a shape in which the width in the door thickness direction narrows toward the -X side. When the sliding door 16 is moved to the open position, the end of the sliding door 16 on the door tail side comes into contact with the inclined surface 200 and is guided inward in the door thickness direction. This allows the sliding door 16 to move smoothly from the closed position to the open position.

This disclosure can also be applied to manual sliding door structures. In this case, the handle that the user grasps to move the sliding door can be directly connected to the sliding door body. This allows the user to apply force directly to the sliding door body.
