Description

The present disclosure relates to sliding door structures.

Conventionally, a sliding door structure is known in which, when the thickness of the sliding door is thicker than the thickness of the door pocket that accommodates the sliding door, the thickness of the sliding door is changed so that the sliding door can be accommodated in the door pocket (for example, Patent Document 1).

JP 2018-066178 A

In Patent Document 1, a guide part is provided that makes it possible to adjust the distance between two door plates in the thickness direction, and guides the two door plates so that they approach each other when the sliding door is shifted from a closed state to an open state. structure is described. A spring is arranged between the two door plates to bias the door plates together in the direction of increasing the thickness.

In the structure of Patent Document 1, the door plates are constantly biased in the direction of increasing the thickness of the sliding door. When opening and closing the sliding door, it is desirable to smoothly adjust the biasing force applied to the door plate.

The present disclosure has been made to solve the above problems, and an object thereof is to provide a sliding door structure having a variable thickness sliding door with high safety.

According to one aspect of the present disclosure, there is provided a sliding door structure including a sliding door that opens and closes an opening provided in a door frame, wherein the sliding door is supported by a sliding door body that can move in a direction to open and close the opening, and a sliding door body. , and at least one door plate movable in the door thickness direction, the sliding door structure moving the door tip side of the door plate outward in the door thickness direction according to the movement of the sliding door body in the closing direction, and then moving the door plate.

Embodiments of the present disclosure will be described below. In the embodiments, a detailed description will be given using an example in which the sliding door structure is provided on the fixed wall of the living space. As a skeleton to which the sliding door structure is attached, a skeleton such as a movable wall may be used in addition to the fixed wall.

In the following embodiments, directions may be described using three-dimensional orthogonal coordinates consisting of the X-axis, Y-axis, and Z-axis. The X-axis extends along the opening/closing direction of the sliding door. The Y-axis is orthogonal to the X-axis in the horizontal plane. The Z-axis extends along the vertical direction.

FIG. 1 is a partial perspective view of a living space to which a sliding door structure is applied. The sliding door structure 10 includes 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 opened. The sliding door 16 is substantially flush with the surface of the fixed wall 12 in the closed position. Thereby, the appearance of the sliding door structure 10 can be improved. The sliding door 16 is housed in a space (a door pocket S described later) provided inside the fixed wall 12 at the open position.

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

The sliding door structure 10 comprises a signal output section 20 arranged on the fixed wall 12 . The signal output unit 20 outputs a drive signal for the sliding door 16 according to the operation of the operator. The signal output unit 20 is composed of a contact-type or non-contact-type operation switch. In this case, the signal output unit 20 outputs the drive signal when the operator operates the operation switch. The drive unit drives the sliding door 16 according to the drive signal. A sensor for detecting whether there is a person or the like within a predetermined range in front of the sliding door 16 may be provided in the blind 18 .

2 and 3 are 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 at the closed position is thinner than the door thickness of the sliding door 16 at the open position. The thickness of the sliding door 16 at the open position is slightly thinner than the thickness of the door pocket S (thickness along the Y-axis direction). The thickness of the sliding door 16 in the closed position is approximately the same as the thickness of the opening 14 closed by the sliding door 16 (ie, the distance between the two oppositely facing surfaces of the fixed wall 12). Thereby, the sliding door 16 forms a flat surface with the surface of the fixed wall 12 in the open position. The thickness of the sliding door 16 increases as it moves from the open position to the closed position. On the other hand, the sliding door 16 becomes thinner as it moves from the closed position to the open position.

The sliding door 16 includes a sliding door body 22 , two door plates 24 , a first moving portion 26 and a second moving portion 28 . The sliding door main body 22 is configured by a frame. The sliding door main body 22 holds other components of the sliding door 16 (the door plate 24, the first moving part 26, the second moving part 28, etc.). The sliding door main body 22 is mechanically connected to a drive unit such as the motor described above. Therefore, the driving force from the driving portion is input to the sliding door main body 22, and the sliding door main body 22 is driven to drive the sliding door 16 as a whole. By using the sliding door body 22 as a frame, the weight of the sliding door body 22 can be reduced. By using the sliding door main body 22 as a frame, parts such as the first moving part 26 and the second moving part 28 can be built in the opening of the frame, and the thickness of the sliding door 16 can be reduced.

The two door plates 24 are arranged to sandwich the sliding door body 22 along the Y-axis. Each door plate 24 is composed of a plate-like member having a first principal surface 30 facing outward in the door thickness direction of the sliding door 16 and a second principal surface 32 facing inward in the door thickness direction. The first main surface 30 may, for example, be decorated identically to the surface of the fixed wall 12 . As a result, the integrity between the sliding door 16 and the fixed wall 12 can be improved when the sliding door 16 is closed. The door plate 24 is suspended from the sliding door body 22 . The door plate 24 moves outward in the door thickness direction or inward in the door thickness direction with respect to the main body of the sliding door body 22 according to the movement of the sliding door 16 . The thickness of the sliding door 16 changes as the position of the door plate 24 relative to the sliding door body 22 changes. In this embodiment, an example in which the two door plates 24 move along the Y-axis with respect to the sliding door body 22 will be described. However, one door plate 24 may be fixed to the sliding door body 22 and only another door plate 24 may be movable with respect to the sliding door body 22 .

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

The first moving part 26 and the second moving part 28 form part of a sliding door moving mechanism that moves the door plate 24 with respect to the sliding door body 22 as the sliding door 16 moves. The first moving part 26 is arranged closer to the door trailing edge than the center in the width direction (X-axis direction) of the sliding door 16, and the second moving part 28 is located closer to the door tip than the center in the width direction (X-axis direction) of the sliding door 16. placed. The first moving part 26 and the second moving part 28 change the position of the door plate 24 with respect to the sliding door body 22 independently of each other.

The first moving portion 26 includes a pair of rear arms 34 and 36 (corresponding to “close link members”) and a pair of slide arms 38 and 40 . The second moving portion 28 includes a pair of front arms 42 and 44 (corresponding to “opening link members”) and a linear guide 46 . A pair of pairs of rear arms 34 and 36 and slide arms 38 and 40 are provided above and below the sliding door 16, respectively. A pair of front arms 42 and 44 are also provided on the upper and lower sides of the sliding door 16, respectively. Thereby, the thickness of the sliding door 16 can be changed simultaneously in the vertical direction.

Each of the rear arms 34 and 36 has a door trailing end and a door leading end. The ends of the rear arms 34 and 36 on the side of the door trailing edge are fixed to the sliding door body 22 and rotatably supported around an axis Z1 extending in the Z-axis direction. Door tip side ends of the rear arms 34 and 36 are attached to the second main surfaces 32 of the two door plates 24, respectively. The ends of the rear arms 34 and 36 on the side of the door are attached to the second main surface 32 so as to be rotatable about the axes Z2 and Z3, respectively. The rear arms 34 and 36 are arranged on the +X side and the -X side, respectively, so as to sandwich the sliding door body 22 when viewed from above.

The slide arms 38 and 40 each have a door trailing end and a door leading end. The ends of the slide arms 38 and 40 on the door bottom side are attached to the second main surfaces 32 of the two door plates 24, respectively. More specifically, the ends of the slide arms 38 and 40 on the door bottom side are attached to the door plate 24 so as to be rotatable about the same axes Z2 and Z3 as the ends of the rear arms 34 and 36 on the door tip side. The ends of the slide arms 38 and 40 on the door tip side are movable with respect to the sliding door body 22 along the X-axis.

FIG. 5 is an enlarged perspective view showing part of the sliding door body. Specifically, as shown in FIG. 5, a gear 100 and a gear damper 102 are provided at the ends of the slide arms 38 and 40 on the side of the door. The ends of the sliding arms 38 and 40 on the side of the door are attached to the shaft of the gear 100 . A combination of the gear 100 and the gear damper 102 applies a deceleration force to the movement of the slide arms 38 and 40 in the closing direction (the acute angle with the X axis becomes smaller). A 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 ends of the rear arms 34, 36 and the ends of the slide arms 38, 40 are held so as to be relatively movable along the X-axis. The ends of the rear arms 34, 36 on the front end side and the ends of the slide arms 38, 40 on the rear end side of the door are rotatably held about the same axes Z2, Z3. According to the first moving portion 26 having such a configuration, the rear arms 34, 36 are moved as the distance between the door trailing end of the rear arms 34, 36 and the door leading end of the slide arms 38, 40 becomes shorter. to the X-axis (the acute angle between them) and the angle of the slide arms 38, 40 to the X-axis (the acute angle between them) increase. As a result, the door plate 24 is separated from the sliding door main body 22 near the first moving portion 26 . On the contrary, the door plate 24 approaches the sliding door main body 22 in the vicinity of the first moving portion 26 as the distance between the ends of the rear arms 34 and 36 on the trailing edge side and the ends of the slide arms 38 and 40 on the leading edge side increases. In other words, by changing the distance between the rear ends of the rear arms 34 and 36 and the ends of the sliding arms 38 and 40 on the front end of the door, the door plate 24 and the sliding door main body 22 can move in the vicinity of the first moving portion 26. You can change the distance. It can also be said that the length of the first moving portion 26 along the X-axis and the length of the first moving portion 26 along the Y-axis are inversely proportional.

The second moving portion 28 is arranged at a position shifted toward the door tip side along the X-axis with respect to the first moving portion 26 . The ends of the front arms 42, 44 on the door bottom side are fixed to the two door plates 24, respectively, and are rotatably supported around axes Z4, Z5 extending in the Z-axis direction. The front ends of the front arms 42 and 44 are supported by linear guides 46, respectively. Specifically, the front ends of the front arms 42 and 44 are rotatably supported around an axis Z6 passing through a linear guide 46 .

The linear guide 46 is held slidably in the X-axis direction along a shaft 48 forming part of the sliding door body 22 . As the linear guide 46 slides toward the door trailing edge, the angle of the front arms 42 and 44 with respect to the X axis (the acute angle between them) increases. As a result, the door plate 24 is separated from the sliding door main body 22 near the second moving portion 28 . Conversely, when the linear guide 46 slides toward the door tip, the door plate 24 approaches the sliding door main body 22 in the vicinity of the second moving portion 28 . That is, by changing the position of the linear guide 46, the distance between the door plate 24 and the sliding door main body 22 can be changed in the vicinity of the second moving portion 28. FIG. It can be said that the length of the second moving portion 28 along the X-axis and the length of the first moving portion 26 along the Y-axis are inversely proportional.

A guide roller 50 (corresponding to a "protrusion") extending from the door plate 24 to the +Z side protrudes from the upper surface of each door plate 24 on the door tip side. The guide roller 50 has a roller that rotates around the Z-axis.

A connecting portion 108 that is connected to the driving portion is provided on the upper portion of the sliding door main body 22 . The connecting portion 108 is fixed to an endless timing belt of the driving portion.

FIG. 6 is a plan view showing the upper portion of the opening. FIG. 6 shows a view when viewing the +Z side from the -Z side (that is, viewing the top of the opening 14 from below). Two grooves 52 (corresponding to a “guide portion” and an “open guide portion”) for guiding the guide roller 50 when the door plate 24 moves are formed in the lower surface of the opening 14 . A 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 edge of the door plate 24 on the door leading edge side. The two grooves 52 extend parallel to the X-axis from the edge of the door trailing edge toward the leading end of the sliding door 16 from the center in the width direction (X-axis direction). The two grooves 52 have a transition portion 54 extending away from each other (in the XY plane) near the end of the door. The two grooves 52 again extend parallel to the X-axis on the door tip side of the transition portion 54 . Alternatively, the groove 52 may be provided on the door plate 24 side and the guide roller 50 may be provided on the lower surface of the opening 14 .

FIG. 7 is a block diagram showing the configuration of the sliding door structure. FIG. 7 shows a functional block diagram in which each component of the sliding door structure is classified according to its function. As shown in FIG. 7 , the sliding door structure 10 includes a sliding door 16 , a signal output section 20 , a drive section 60 and a door plate moving mechanism 62 . The drive unit 60 corresponds to a frame drive unit, has a motor, a pulley, a timing belt, etc., and drives the sliding door 16 to open or close. The door plate moving mechanism 62 changes the thickness of the sliding door 16 . In FIG. 7, in order to make the explanation clearer, the drive unit 60 that drives the sliding door 16 and the door plate moving mechanism 62 that changes the thickness of the sliding door 16 are separated from a functional point of view. The door plate moving mechanism 62 includes a first moving portion 26 , a second moving portion 28 , and a guide mechanism 64 including grooves 52 and guide rollers 50 .

The operation of the sliding door structure will be described below. At this time, it is assumed that the sliding door 16 is in a state of closing the opening 14 . At this time, each door plate 24 is at a position separated from the sliding door main body 22, and the sliding door 16 is in a swollen state.

When an operator who wants to open the sliding door 16 operates the signal output section 20 , the signal output section 20 outputs an opening drive signal to the drive section 60 . As a result, the drive unit 60 drives the motor or the like to start opening the sliding door 16 . When the sliding door 16 starts to open, the first moving part 26 mainly brings the door plate 24 closer to the sliding door main body 22 on the trailing edge side, and reduces the thickness of the sliding door 16 on the trailing edge side. Next, as the sliding door 16 continues to open, the door plate moving mechanism 62 brings the door plate 24 closer to the sliding door main body 22 on the door tip side, thereby reducing the thickness of the sliding door 16 on the door tip side. As a result, the sliding door 16 is shrunk to a thickness that fits in the door pocket S.

When the sliding door structure 10 determines that there is no person around the sliding door 16, the sliding door structure 10 closes the sliding door 16.例文帳に追加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 plate 24 separates from the sliding door main body 22 mainly by the action of the second moving portion 28 , the guide roller 50 and the groove 52 . As a result, the thickness of the sliding door 16 increases on the door tip side, and the door tip side of the sliding door 16 bulges in the door thickness direction. When the sliding door 16 continues to be closed, the door plate 24 is separated from the sliding door main body 22 mainly by the action of the first moving portion 26 on the door bottom side. As a result, the thickness of the sliding door 16 is increased on the door bottom side, and the door bottom side of the sliding door 16 bulges in the door thickness direction. Thereby, the sliding door 16 forms a flat surface with the surface of the fixed wall 12 .

When opening 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 plate 24 approaches the sliding door main body 22 mainly due to the action of the first moving portion 26 . As a result, the thickness of the sliding door 16 is reduced on the door tip side, and the door trailing edge side of the sliding door 16 shrinks in the door thickness direction. When the sliding door 16 continues to be closed, the door plate 24 approaches the sliding door main body 22 mainly due to the action of the second moving portion 28 on the door tip side. As a result, the thickness of the sliding door 16 is reduced on the door tip side, and the door tip side of the sliding door 16 shrinks in the door thickness direction. As a result, the sliding door 16 has a thickness that can be accommodated in the door pocket S.

In the above description, the expression "mainly acting" also includes that the corresponding component acts mainly and that other components also act secondarily. For example, when the sliding door 16 is moved from the closed position to the open position, the thickness of the sliding door 16 is mainly reduced by the first moving part 26. Other components such as the guide rollers 50 also act secondarily to hold the position of the door plate 24 with respect to the sliding door body 22 .

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

As shown in FIG. 8 , when the sliding door 16 is in the closed position, the end of the sliding door 16 on the side of the door is in contact with the vertical beam 66 . The rear arms 34, 36, the slide arms 38, 40, and the front arms 42, 44 are in the most open state (that is, the state with the largest acute angle with the X axis). In this state, the door plate 24 is held parallel to the X-axis at a position away from the sliding door body 22 . When the drive unit 60 (see FIG. 7) is driven in this state to drive the sliding door main body 22 to the -X side, the state shifts to the state shown in FIG.

As shown in FIG. 9, when the sliding door 16 is driven to the -X side, the sliding door main body 22 is pulled to the -X side, and the ends of the rear arms 34 and 36 on the side of the door trailing edge are pulled to the -X side. The ends of the slide arms 38 and 40 on the door tip side and the linear guide 46 are not fixed to the sliding door body 22 . Therefore, immediately after the sliding door main body 22 is driven, the ends of the slide arms 38 and 40 on the front end side and the linear guide 46 try to stay at their current positions. When the ends of the rear arms 34 and 36 on the trailing edge side are pulled toward the -X side, a pulling force acts on the rear arms 34 and 36 in the axial direction. As a result, the ends of the rear arms 34, 36 on the side of the door bottom rotate about the axis Z1 extending in the Z-axis direction, while the ends of the rear arms 34, 36 on the side of the door leading edge rotate about the axes Z2, Z3. A force F1 that approaches the sliding door main body 22 is generated. The force F1 acts in a direction to draw the door plate 24 into the door pocket S. Accordingly, the ends of the slide arms 38, 40 on the door leading edge side slide along the X axis toward the door leading edge side, and the angle (acute angle) formed between the slide arms 38, 40 and the X axis becomes smaller. That is, 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 remains substantially unchanged on the door tip side. When the drive unit 60 (see FIG. 7) is driven in this state to drive the sliding door main body 22 to the -X side, the state shown in FIG. 10 is obtained.

When the drive unit 60 (see FIG. 7) continues to be driven, as shown in FIG. 10, the sliding door main body 22 is pulled to the -X side, and the door plate 24 is also pulled to the -X side. As the door plate 24 moves, the guide roller 50 also moves along the groove 52 . When the guide roller 50 enters the transition section 54, the two door panels 24 move toward each other. As a result, the door plate 24 approaches the sliding door main body 22 on the door tip side. As a result, the sliding door 16 has a thickness that can be accommodated in the door pocket S.

Thereafter, by continuing to drive the driving portion 60, the sliding door 16 is housed in the door pocket S as shown in FIG.

12 and 13 are horizontal sectional views showing a series of operations when moving the sliding door from the open position to the closed position. 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, the slide arms 38, 40 and the front arms 42, 44 are in the most closed state (that is, the smallest acute angle with the X axis). state). In this state, the door plate 24 is held in parallel with the X-axis at a position close to the sliding door body 22 . In this state, when the driving unit 60 (see FIG. 7) is driven to drive the sliding door body 22 to the +X side, the door plate 24 moves together with the sliding door body 22 as the sliding door body 22 moves to the +X side. .

As shown in FIG. 12, when the guide rollers 50 enter the transition section 54, the two door panels 24 begin to move away from each other. As a result, the door thickness of the sliding door 16 increases on the door tip side. At this time, the ends of the front arms 42, 44 on the side of the front door rotate about the axis Z6, and the acute angle formed by the front arms 42, 44 with respect to the X axis increases. Along with this, the linear guide 46 moves toward the door tail side with respect to the sliding door main body 22 . The end of the door tip side of the two door plates 24 is positioned on the +X side with respect to the sliding door main body 22 . Therefore, when the sliding door 16 is moved to the +X side, the end of the door plate 24 on the door tip side comes into contact with the vertical beam 66 before the end of the sliding door body 22 on the door tip side. By continuing to drive the sliding door body 22 in the +X direction even after the end of the door plate 24 on the side of the door tip contacts the vertical beam 66, the door plate 24 does not move along the +X direction, but the sliding door body 22 moves in the +X direction. . That is, the sliding door body 22 moves independently of the door plate 24 . As a result, the ends of the rear arms 34 and 36 on the door bottom side move in the +X direction while the positions of the ends on the door tip side of the rear arms 34 and 36 in the X-axis direction are fixed. As a result, the acute angle formed by the rear arms 34 and 36 with respect to the X axis increases, and a force F2 acts on the door plate 24 in the direction of opening the door plate 24 . As a result, the door thickness of the sliding door 16 increases on the door bottom side. The drive unit 60 stops at the timing when the sliding door main body 22 contacts the vertical beam 66 . As a result, as shown in FIG. 13, the door thickness of the sliding door 16 is the same on the door tail side and the door tip side.

As described above, according to the sliding door structure 10, the thickness of the sliding door 16 can be changed independently of the front end side and the rear end side in conjunction with the movement of the sliding door 16 along the X axis. At this time, since the thickness of the sliding door 16 can be smoothly adjusted without using a biasing member such as a spring, high safety can be obtained. Moreover, since it can be changed, it is possible to prevent the door plate 16 from suddenly popping out. Further, it is possible to prevent the sliding door 16 from accelerating due to the door plate 24 jumping out and coming into contact with the vertical bar. This increases safety.

In addition, by using the second moving part 28 having front arms 42 and 44, one end of which is fixed to the door plate 24 and the other end of which is slidably held, a biasing force such as a spring is applied when the sliding door 16 is driven to close. The sliding door 16 can be inflated according to the sliding door 16 without using any means. This increases safety.

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

Further, by driving the driving unit 60 according to the driving signal from the signal output unit 20 and thereby driving the sliding door 16, the sliding door structure 10 can be applied to an automatic door.

Further, the thickness of the sliding door 16 is changed to a thickness that can be accommodated in the door pocket S by bringing the door plate 24 closer to the sliding door body 22 as the sliding door body 22 moves in the opening direction.

At this time, by using the first driving section 26 having rear arms 34 and 36, one end of which is fixed to the door plate 24 and the other end of which is slidably held, a biasing force such as a spring is applied when driving the sliding door 16 to open. The sliding door 16 can be collapsed according to the sliding door 16 without using any means. This increases safety.

Modifications of the embodiment will be described below. FIG. 14 is a horizontal sectional view of a sliding door structure according to a modification. As shown in FIG. 14, the entrance to the door pocket S may be provided with an inclined surface 200 . The inclined surface 200 is formed on the inner surface in the door thickness direction of the vertical beam on the door bottom 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 side of the door trailing edge comes into contact with the inclined surface 200 and is guided inward in the door thickness direction. Thereby, the operation of the sliding door 16 can be made smooth when the sliding door 16 is moved from the closed position to the open position.

Note that the present disclosure is also applicable to manual sliding door structures. In this case, the handle that the user grips when moving the sliding door may be directly connected to the main body of the sliding door. This allows the user to directly apply force to the sliding door body.
