JP 2010-71051 A Japanese Patent No. 5177895

  When a sliding door device as described in Patent Document 2 is applied to a living staircase structure as described in Patent Document 1, the sliding door body opens and closes the communication opening on the living side.

  In this case, when the sliding door body is fully open, the remaining margin (that is, the length in the opening and closing direction of the portion where the door tip of the sliding door body that is fully opened projects to the opening side) is “0”. The user on the side cannot see the puller or place a finger on the puller. This is because the puller is covered with the wall surface from the staircase side, and conventionally, the distance between the sliding door body and the wall surface is only about 20 mm. As a result, convenience during opening and closing is impaired. Therefore, conventionally, a leaving margin of 70 mm or more is set.

  However, since the effective opening width of the communication opening becomes shorter as the remaining margin becomes longer, it is desired to shorten the remaining margin.

  The present invention has been made in view of such circumstances, and a main object of the present invention is to provide a sliding door device and a staircase device that can achieve both convenience at the time of opening and closing and shortening of a leaving margin.

  The sliding door device according to the present invention faces a wall surface and is movable in a lateral direction along the wall surface, and is an upward-sliding sliding door body that opens and closes an opening adjacent to the wall surface, and faces the wall surface of the sliding door body. In a sliding door device comprising a first puller provided on one surface of the sliding door and a second puller provided on the other surface opposite to the one surface of the sliding door body, the wall surface and the one surface A space is provided between which a hand can be inserted.

  The sliding door device according to the present invention is characterized in that a separation distance in a facing direction between the wall surface and the one surface is 30 mm or more.

  The sliding door device according to the present invention is characterized in that the first puller and the second puller are respectively digging pullers.

  In the sliding door device according to the present invention, the vertical length of the first puller is longer than the vertical length of the second puller, and the upper end position of the first puller is higher than the upper end position of the second puller, or The lower end position of the first puller is lower than the lower end position of the second puller.

  The sliding door device according to the present invention is characterized in that the first puller is arranged closer to the door end than the second puller.

  The sliding door device according to the present invention is long in the vertical direction, separated from the peripheral edge of the opening in the wall by an appropriate length, and attached to the wall, and the bar when the opening is closed by the sliding door body And a packing that covers a gap between the sliding door main bodies.

  The sliding door device according to the present invention is characterized in that a margin for leaving the sliding door body is longer than a distance from a door tip of the sliding door body to a door tip side end portion of the first puller.

  The sliding door device according to the present invention is characterized in that a margin for leaving the sliding door body is shorter than a distance from a door tip of the sliding door body to a door bottom side end portion of the first puller.

  The staircase device according to the present invention includes the sliding door device according to the present invention, and a staircase that communicates the upper floor and the lower floor and is raised and lowered through the opening.

  The stairway device according to the present invention includes the sliding door device according to the present invention, and a staircase that communicates between the upper floor and the lower floor and is raised and lowered through the opening, and the sliding door device is disposed on the lower floor side, The upper end position of the first puller is higher than the upper end position of the second puller.

  The staircase device according to the present invention comprises the sliding door device according to the present invention, and a staircase that communicates between the upper and lower floors and is raised and lowered through the opening, and the sliding door device is disposed on the upper floor side, The lower end position of the first puller is lower than the lower end position of the second puller.

In the present invention, a space in which a hand can be inserted (hereinafter referred to as an insertion space) is provided between the wall surface adjacent to the opening and the one surface on the wall surface side of the sliding door body. Therefore, the user can easily insert the hand into the insertion space and place the finger on the first pulling hand. In addition, it is easy for the user to visually recognize the first puller through the insertion space. As a result, there is no need to set a long margin.
The second puller does not face the wall. Therefore, the user can easily place a finger on the second puller and can easily view the second puller.
Such a sliding door device is particularly useful when configuring a staircase device.

  In the present invention, the insertion space is provided by making the separation distance between the wall surface and one surface of the sliding door main body 10 mm or more longer than the conventional one.

In the present invention, the first puller (and the second puller) is the digging puller. That is, a concave puller is provided on one surface (and the other surface) of the puller main body.
Therefore, compared with the case where the first puller is convex, it is possible to suppress the inconvenience that the first puller narrows the insertion space. Moreover, compared with the case where the second puller is convex, it is possible to suppress the inconvenience that the second puller narrows the space (for example, the living room) facing the other surface of the sliding door main body.

In the present invention, the first puller is longer on the upper side than the second puller. Such a configuration is suitable when the sliding door body is on the downstairs side. This is because the user on the stairs side can easily reach the first puller from a position higher than the floor surface below the floor.
Alternatively, the first puller is longer on the lower side than the second puller. Such a configuration is suitable when the sliding door body is on the upper floor. This is because the user on the stairs side can easily reach the first puller from a position lower than the floor on the floor.

  In the present invention, the first puller is arranged closer to the door end than the second puller. Therefore, compared with the case where the arrangement position of the 1st puller's horizontal direction is the same as that of the 2nd puller, the undrawn margin can be shortened.

In the present invention, the bar is attached to the wall surface away from the peripheral edge of the opening. Therefore, the horizontal position of the bar can be easily adjusted when the bar is attached.
The packing that covers the gap between the bar and the sliding door body can suppress unnecessary air flow through the opening.

  In the present invention, even if the sliding door main body is fully opened, at least a part of the first pulling hand can be reliably recognized.

In the present invention, even if the sliding door main body is fully opened, at least a part of the first pulling hand can be reliably recognized.
Moreover, the amount left is not too long. This is because, when the sliding door body is fully opened, the door bottom side is covered with the wall surface at least from the first pulling handle of the sliding door body.

  According to the sliding door device of the present invention, the user can easily place a finger on each of the first puller and the second puller without setting a long left margin, and can easily recognize the puller and the second puller. Therefore, it is possible to achieve both convenience at the time of opening and closing and shortening of the leaving margin.

The guide rail 211 (see FIG. 3) of the sliding door device 2 is a so-called ceiling-embedded joinery rail, and is embedded in the ceiling plate C1. The length direction of the guide rail 211 is the left-right direction. The left end portion (and the right end portion) of the guide rail 211 is disposed on the front side of the wall surface Ba (and the wall surface Bb), and the central portion in the left-right direction of the guide rail 211 is disposed on the front side of the communication opening E1.
The traveling bodies 22 and 22 (only one is shown in FIG. 3) are juxtaposed apart from each other in the left-right direction. Each traveling body 22 includes a traveling unit 221 that travels in the left-right direction while being guided by the guide rail 211, and a hanging unit 222 that projects downward from the traveling unit 221.

The sliding door main body 23 has a rectangular flat plate shape extending in the vertical and horizontal directions. The sliding door body 23 has a front surface 23a and a rear surface 23b. The sliding door body 23 is arranged in the living space F.
The upper side portion of the sliding door main body 23 is attached to the hanging portions 222 and 222 of the traveling bodies 22 and 22. Therefore, the sliding door body 23 moves in the left-right direction as the traveling bodies 22 and 22 travel.
That is, the sliding door body 23 faces the wall surfaces Ba and Bb in the front-rear direction and is movable in the lateral direction along the wall surfaces Ba and Bb. The rear surface 23b is one surface facing the wall surfaces Ba and Bb of the sliding door main body 23, and the front surface 23a is the other surface opposite to the rear surface 23b.

  The distance in the front-rear direction between the wall surfaces Ba and Bb and the rear surface 23b (hereinafter referred to as clearance G1; see FIGS. 4 and 5) is at least 30 mm, and is 39 mm in the present embodiment. Since the clearance according to the conventional sliding door device is about 20 mm, the clearance G1 is 1.5 times longer than the conventional one.

  The sliding door main body 23 is a suspended type suspended from the guide rail 211 via the traveling bodies 22 and 22, and opens and closes the communication opening E1 in the left-right direction. When the communication opening E1 is opened, the sliding door main body 23 moves to the right side, and when the communication opening E1 is closed, the sliding door main body 23 moves to the left side.

The left end of the puller 24 is spaced 31 mm from the left side of the sliding door body 23.
The dimensions of the puller 24 and the arrangement on the front surface 23a are not significantly different from those of a general puller. That is, the puller 24 is at such a height that a user standing on the floor board D1 can easily reach.

The puller 251 is a digging puller provided on the rear surface 23 b of the sliding door body 23.
In the present embodiment, the vertical length of the puller 251 is 838 mm, and the horizontal width is 32 mm. The upper end portion (and the lower end portion) of the pulling handle 251 is located at a height separated from the lower side portion of the sliding door main body 23 by 1674 mm (and 836 mm). The left end of the puller 251 is separated from the left side of the sliding door body 23 by 7 mm.
That is, the vertical length of the puller 251 is longer than that of the puller 24, the lateral width of the puller 251 is shorter than that of the puller 24, and the upper end position of the puller 251 is higher than that of the puller 24. The puller 251 is arranged closer to the door end than the puller 24. The leaving margin G2 of the sliding door main body 23 is longer than the distance G3 from the door tip of the sliding door main body 23 to the door tip side end of the pulling handle 251, and the door bottom side end of the sliding door 251. It is shorter than the distance G4 to the part (see FIG. 5).

When the communication opening E1 is completely closed, the left part and the left-right center part of the puller 251 are arranged in front of the wall surface Ba, but the right part of the puller 251 (from the right end of the puller 251 in the left-right direction). A range of about 10 mm in length) protrudes toward the communication opening E1.
When the communication opening E1 is completely opened, the right half of the puller 251 is arranged in front of the wall surface Ba, but the left half of the puller 251 (the length of about 15 mm in the horizontal direction from the left end of the puller 251). Range) protrudes toward the communication opening E1.

The bar 261 has a parting material 26a and a door stop material 26b (see FIG. 4).
The parting material 26a has a rectangular column shape that is long in the vertical direction. The length of the parting material 26a in the front-rear direction is 30 mm, which is shorter than the clearance G1. The sliding door body 23 moves in the left-right direction on the front side of the parting material 26a.
The rear surface of the parting material 26a and the wall surface Ba are in contact with each other. The parting material 26a is attached to the wall surface Ba at a distance of 12.5 mm to the left from the peripheral edge (the right side of the wall surface Ba) of the communication opening E1.

  The door stop material 26b is a hollow member, and is attached to the left side of the front surface of the parting material 26a. The sum of the longitudinal lengths of the parting material 26a and the door stop material 26b is 49 mm, which is longer than the clearance G1. The sliding door main body 23 contacts and separates in the left-right direction with respect to the right surface of the door stop material 26b.

The rod 27 has a rectangular column shape that is long in the vertical direction, and functions as a parting material. The vertical length and cross-sectional dimensions of the bar 27 of the bar 27 are approximately the same as the parting material 26a. The sliding door body 23 moves in the left-right direction on the front side of the bar 27.
The rear surface of the bar 27 and the wall surface Bb are in contact. The bar 27 is attached to the wall surface Bb with a distance of 44 mm to the right from the peripheral edge (the left side of the wall surface Bb) of the communication opening E1.

The packing 28 (see FIG. 4) is an elastic member. The packing 28 is supported by the door stop material 26b, and has a plate shape that protrudes diagonally to the right rear side from the right front end of the door stop material 26b.
When the communication opening E <b> 1 is completely closed, the packing 28 is sandwiched between the door stop material 26 b and the left end surface of the sliding door main body 23. As a result, the packing 28 covers the gap between the bar 261 and the sliding door body 23.

The packing 29 (see FIG. 6) moves in the left-right direction as the sliding door body 23 moves in the left-right direction. The packing 29 includes a packing main body 291 and a main body support portion 292.
The packing main body 291 is an elastic member and has a flat plate shape extending in the up-down and front-back directions.
The main body support portion 292 is attached to the right side portion of the rear surface of the sliding door main body 23. The main body support portion 292 supports the packing main body 291 in such a posture that the packing main body 291 protrudes backward from the right side portion on the rear surface of the sliding door main body 23.

When the communication opening E1 is completely closed, the left surface of the packing body 291 contacts the right surface of the bar 27. As a result, the packing 29 covers the gap between the sliding door body 23 and the bar 27.
The sliding door device 2 may include a packing attached to the sliding door main body 23 instead of the packing 28, or may include a packing attached to the bar 27 instead of the packing 29.

When the communication opening E1 is completely closed, a space surrounded by the rear surface 23b of the sliding door body 23, the right surface of the parting member 26a, and the wall surface Ba is formed. This space functions as the insertion space 31 (see FIGS. 1 and 4). The left part and the center part in the left-right direction of the puller 251 are arranged in the insertion space 31.
When the communication opening E1 is completely opened, a space surrounded by the rear surface of the sliding door body 23, the left surface of the bar 27, and the wall surface Bb is formed. This space functions as the insertion space 32 (see FIGS. 2 and 5). The right half of the puller 251 is disposed in the insertion space 32.
Each of the insertion spaces 31 and 32 has a size capable of inserting a user's hand.

In the case of the stairway device 1 as described above, since the remaining margin G2 of the sliding door main body 23 is shorter than the conventional one, the effective opening width G5 (see FIG. 2) is longer than the conventional one.
The user in the living space F places the finger on the pulling hand 24 and moves the sliding door body 23 laterally. For the user in the living space F, the puller 24 is easy to visually recognize and easy to put on a finger.
On the other hand, the user who goes up and down the stairs 11 puts his finger on the pulling hand 251 and moves the sliding door body 23 laterally. Below, the user who goes up and down the stairs 11 is demonstrated.

  When the communication opening E1 is completely closed, the user inserts his / her hand into the insertion space 31, puts his / her finger on the puller 251, and moves the sliding door body 23 in the right direction. When the communication opening E1 is completely closed, the user puts his / her finger on the pulling handle 251 and moves the sliding door main body 23 leftward. At this time, the user's hand may be inserted into the insertion space 31 as the sliding door body 23 moves. However, since the insertion space 31 is sufficiently wide (particularly, the clearance G1 is longer than the conventional one), the finger inserted into the pull handle 251 is sandwiched between the sliding door body 23 and the wall surface Ba. There is no fear of it.

  When the communication opening E1 is completely open, the user inserts his / her hand into the insertion space 32, puts his / her finger on the pulling hand 251, and moves the sliding door body 23 leftward. Further, when the communication opening E1 is completely opened, the user puts a finger on the pulling handle 251 and moves the sliding door main body 23 in the right direction. At this time, the user's hand may be inserted into the insertion space 32 as the sliding door body 23 moves. However, since the insertion space 32 has a sufficient width (particularly, the clearance G1 is longer than the conventional one), the finger inserted into the pull handle 251 is sandwiched between the sliding door body 23 and the wall surface Bb. There is no fear of it.

The user can easily visually recognize the pull handle 251 when the communication opening E1 is completely closed.
This is because the right part of the puller 251 protrudes toward the communication opening E1, and the right part of the puller 251 can be surely recognized without being obstructed by the wall plate B3. Moreover, since the left part and left-right direction center part of the puller 251 are fully separated from the wall surface Ba, the left part and left-right direction center part of the puller 251 can be visually recognized through the insertion space 31. .

Further, even when the communication opening E1 is completely opened, the user can easily visually recognize the pulling handle 251.
This is because the left half of the puller 251 protrudes to the communication opening E1 side, so that the left half of the puller 251 can be surely seen without being inhibited by the wall plate B4. Further, the right half of the puller 251 is sufficiently separated from the wall surface Bb, so that the right half of the puller 251 can be visually recognized through the insertion space 32.

That is, due to the presence of the insertion spaces 31 and 32, the pulling hand 251 is easy to visually recognize and is easy to put a finger.
The sliding door device 2, and thus the staircase device 1, is easy to visually recognize the pulling hands 24 and 251 and is easy to put a finger on the pulling hands 24 and 251, so that it is highly convenient when opening and closing.
Furthermore, since the puller 251 is longer on the upper side than the puller 24, not only when the user is positioned on the floor board D1, but also at the lowest step of the staircase 11 or the second to fourth steps from the bottom. Even if it is located anywhere, the hand can easily reach the puller 251. If the length of the puller 251 is approximately the same as that of the puller 24, the user is positioned on the floor plate D1 or the lowest step of the stairs 11 in order to put his finger on the puller 251. Need to be. That is, the puller 251 improves convenience when opening and closing the communication opening E1 from the staircase 11 side.

  By the way, although the pullers 24 and 251 are both concave, they may be convex. However, since the convex puller 24 protrudes into the living space F, the living space F is narrowed compared to the concave shape. In addition, since the convex puller 251 protrudes into the insertion spaces 31 and 32, the insertion spaces 31 and 32 are narrowed compared to the concave shape. As a result, it may be more difficult to place a finger on the puller 251 than in the concave case.

  Although the puller 251 of the present embodiment is arranged closer to the door end than the puller 24, the arrangement position in the left-right direction may be the same as that of the puller 24. However, when the puller 251 is arranged closer to the door-end side than the puller 24, the unloading margin G2 is shortened as compared to the case where the positions of the puller 251 and the puller 24 in the left-right direction are the same. Can do.

  The bars 261 and 27 are attached to the wall surfaces Ba and Bb. On the other hand, a general parting material provided in the conventional sliding door device has an L-shaped cross section, and is a corner of the wall Ba and the right end surface of the wall plate B1 and the right surface of the wall plate B3, or the wall surface Bb and the wall plate B2. Are attached to the corner of the left end surface of the wall plate and the left surface of the wall plate B4. Therefore, each of the bar members 261 and 27 can easily adjust the position in the left-right direction of each of the bar members 261 and 27 when the bar members 261 and 27 are attached, compared to the conventional parting material.

The packings 28 and 29 suppress the unnecessary passage of air between the living space F and the space on the stairs 11 side through the communication opening E1 when the communication opening E1 is completely closed.
As a result, the living space F is compared with any of the case where the sliding door device 2 is not provided and the case where a conventional sliding door device not provided with the packings 28 and 29 is provided instead of the sliding door device 2. However, the air conditioning efficiency can be improved.

  In the case of the staircase device 1, the sliding door main body 23 protrudes toward the living space F than the sliding door main body included in a general sliding door device. Therefore, even if the staircase 11 has a configuration in which the front end portions of the side plates 112 and 112 protrude somewhat into the living space F, the sliding door body 23 and the front end portions of the side plates 112 and 112 do not interfere with each other.

The sliding door device 2 is not limited to the configuration provided in the staircase device 1.
The sliding door body 23 is not limited to the configuration that opens to the right, and may be configured to open to the left.
Although the sliding door main body 23 is a single sliding door, the sliding door device 2 may be provided with a double sliding door or a pulling door instead of the sliding door main body 23.

A pulling handle similar to the pulling handle 251 may also be provided on the front surface 23 a of the sliding door main body 23.
However, the puller 24 is more suitable for the front surface 23 a than the puller similar to the puller 251. This is because, in the living space F, it is unlikely that the upper side of the puller similar to the puller 251 is utilized. In the living space F, there is a possibility that a sliding door or a swing door other than the sliding door main body 23 is arranged. Since the dimensions of the puller 24 and the arrangement on the front surface 23a are not significantly different from those of a general puller, a sense of design unification can be obtained between the sliding door body 23 and a sliding door or a hinged door other than the sliding door body 23. It is done.

In the present embodiment, the wall plates B1 and B2 are separate bodies. However, the communication opening E1 may be formed in one wall plate. In this case, the guide rail 211 is not limited to the structure provided in the ceiling board C1. For example, a rail support member that supports the guide rail 211 while concealing it from the living space F side may be attached to the upper side of the communication opening E1 on the front surface of the wall plate.
The sliding door device 2 may include a guide rail attached to the lower surface of the ceiling plate C1 instead of the guide rail 211.
