Description

  The present invention relates to a partition structure of a building.

  In a building such as a house, a so-called LDK space in which a living room, a dining room, and a kitchen are formed as a continuous space on the first floor may be provided as a living room space. Such an LDK space has an advantage that the feeling of opening in the building can be enhanced.

  Some buildings having such an LDK space are provided with a staircase space adjacent to the LDK space in which stairs for moving back and forth between the first floor portion and the second floor portion are installed. In such a building, it is conceivable that the LDK space is made continuous with the staircase extending over the upper and lower floors through a stairway opening for entering and exiting the stairway from the LDK space. In that case, it is possible to further increase the feeling of opening the LDK space.

  Here, it is conceivable that a movable partition is installed in the LDK space and the LDK space is partitioned by the partition as necessary. As this type of partition, for example, a lattice partition formed in a lattice shape (continuous shape) by a plurality of vertical bars can be used (for example, see Patent Document 1). If the lattice partition is used, the LDK space can be partitioned while ensuring lighting and ventilation through the gaps between the vertical bars, so that each space partitioned by the partition can be made comfortable.

JP 2007-162391 A

  By the way, in the above-mentioned building where the LDK space and the staircase space are arranged adjacent to each other, it is conceivable that the warm air in the LDK space flows out to the second floor through the staircase space when heating is performed by the air conditioner in the LDK space. In that case, there is a concern about a decrease in air conditioning efficiency (heating efficiency) in the LDK space.

  This invention is made | formed in view of the said situation, and makes it the main objective to provide the partition structure of the building which can suppress the fall of air-conditioning efficiency in living room space.

  In order to solve the above problems, the partition structure of the building of the first invention has a plurality of floors, and in each of the floors, there is a living room space and an upper or lower floor of the floor. A staircase space having a stairway that leads to the staircase space, the staircase space being surrounded by a surrounding wall, and a stairway that allows a part of the surrounding wall to enter and exit the staircase space from the living room space Applied to a building in which an opening is formed, and includes a movable lattice partition in which a plurality of long materials are assembled in a lattice shape, and the lattice partition is a space on both sides sandwiching the living room space between the lattice partitions. Between the first position for partitioning and the second position for covering the staircase opening and partitioning the living room space and the staircase space, and A closed state that closes the gap between the gap and the gap Characterized in that it comprises a switching means which is operable between an open state to open the.

  According to the present invention, the living room space and the staircase space can be partitioned by moving the lattice partition to the second position. And in the partitioning state, by closing the opening / closing means, the gap between the long members of the lattice partitioning is closed, so that the ventilation between the living room space and the staircase space through the gap can be blocked. As a result, when air conditioning (cooling or heating) is carried out by the air conditioner in the living room space, the air (cold air or warm air) in the living room space flows into the staircase space, and thus the upper or lower floor through the staircase space. Therefore, it is possible to suppress a decrease in air conditioning efficiency.

  When the lattice partition is arranged at the first position and the living room space is partitioned, if the gap between the long materials is opened, lighting and ventilation can be made through the gap. Both spaces can be made comfortable. Moreover, when the lattice partition is arranged in the second position to partition the living room space and the staircase space, since the movement from the living room space to the staircase space can be blocked, pets, infants, etc. can move freely from the living room space to the staircase space. You can also prevent the situation of going up and down the stairs.

  The partition structure of a building according to a second aspect of the present invention is the structure according to the first aspect, wherein the lattice partition is configured by connecting a plurality of longitudinal bars as the long members arranged side by side through connecting members. The connecting member connects the vertical bars so that they can be displaced relative to each other so that the interval between the adjacent vertical bars is variable, and the opening / closing means is each of the adjacent vertical bars. The vertical bars are brought into the closed state by being brought into contact with each other, and are brought into the opened state by being separated from each other.

  In general, the staircase opening and the living room space have different width dimensions, and the staircase opening is narrower than the living room space. From this point, the width dimension to be partitioned differs between when the lattice partition is at the first position and when it is at the second position. In this respect, according to the present invention, adjacent vertical bars are arranged with a space therebetween, whereby a gap is formed (opened) between the vertical bars, while adjacent vertical bars are brought into contact with each other. By being arranged, the gap is closed, and as a result, the horizontal width of the lattice partition can be adjusted in accordance with the opening and closing of the gap. Specifically, when the gap is opened (formed), the lateral width of the lattice partition can be increased, and when the gap is closed (not formed), the lateral width of the lattice partition can be decreased. Therefore, when the interstitial partition is arranged at the first position to partition the living room space, the living room space can be partitioned over a wide range by opening the gap. On the other hand, when the lattice partition is arranged at the second position to partition the stair space and the living room space, the amount of the lattice partition that protrudes from the stairway opening in the state where the gap is closed can be reduced. It is possible to partition both the spaces while suppressing inconveniences such as the protruding portion interfering with walking. That is, according to the present invention, it is possible to conveniently adjust the partition width while optimizing each ventilation state.

  In the partition structure of the building of the third invention, in the second invention, each of the adjacent vertical bars is provided so as to be movable with respect to the connecting member that connects both of them. The interval between adjacent vertical beams is adjustable, and the connecting member is configured to be extendable and contractible, and the interval between the adjacent vertical beams can be adjusted by the expansion and contraction. And

  According to the present invention, the distance between the vertical bars can be adjusted by sliding the adjacent vertical bars with respect to the connecting member or by extending or contracting the connecting member. Thus, the adjustment range of the lateral width of the lattice partition can be increased. Therefore, the ratio of each width can be increased for the horizontal width of the grid partition when the gap between the vertical bars is closed and the horizontal width of the grid partition when the gap between the vertical bars is opened, As a result, the effect of the second invention can be suitably obtained.

  According to a partition structure of a building of a fourth invention, in the first invention, the lattice partition includes a plurality of partition panels configured by providing a plurality of vertical bars as the long members side by side. The partition panel is provided so as to be slidable in the width direction in a state where at least a part of the partition panel is overlapped. One of the partition panels is a partition panel, and in the closed state, the one partition panel is disposed at a position where its own vertical beam is alternated with the vertical beam of the other partition panel. In the partition panel, all the gaps formed between the adjacent vertical bars are closed, and in the open state, the vertical bars of the other partition panel and the interstices are separated. By being opposed in the thickness direction of, characterized in that opening the gap of the other partition panel.

  According to the present invention, by shifting one partition panel among the partition panels in the widthwise direction with respect to the other partition panel, the vertical bars of one of the partition panels are arranged between adjacent vertical bars of the other partition panel. Can be opened and closed. In this case, since the gaps of the other partition panel can be opened / closed at a time only by shifting the position of one of the partition panels, the opening / closing operation of the gap can be facilitated.

  A partition structure of a building according to a fifth invention is characterized in that, in any one of the first to fourth inventions, a guide rail for guiding the movement of the lattice partition is provided.

  According to the present invention, since the lattice partition can be moved along the guide rail, the lattice partition moving operation can be suitably performed.

  A partition structure of a building according to a sixth aspect of the present invention is characterized in that, in any one of the first to fifth aspects of the invention, the partition structure includes a blocking means for blocking the movement of the lattice partition.

  According to the present invention, the lattice partition can be held at a predetermined position (first position or second position) by preventing the movement of the lattice partition by the blocking means. Therefore, a stable installation state can be realized even with a movable grid partition.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a two-story building having a first floor part and a second floor part is embodied. FIG. 1 is a plan view showing a floor plan of the first floor portion.

  As shown in FIG. 1, a living room 11, a dining room 12, a kitchen 13, and a Japanese-style room 14 are provided on the first floor of the building 10, and the entrance 15, the bathroom 16, the dressing room 17, and the non-room space are provided. A staircase space 18 is provided. Among them, the living room 11, the dining room 12, and the kitchen 13 are arranged on the south side of the first floor part, and the Japanese-style room 14, the bathroom 16, the dressing room 17 and the staircase space 18 are arranged on the north side of the first floor part.

  The living room 11, the dining room 12, and the kitchen 13 are formed as a continuous integrated space (that is, the LDK space 20), and the living room 11 is provided with an air conditioner 21 including an air conditioner. The air conditioner 21 can perform cooling and heating for the LDK space 20.

  The Japanese room 14 is provided adjacent to the living room 11 (in other words, the LDK space 20). A partition wall made of a fixed wall is not provided between the living room 11 and the Japanese-style room 14, and therefore an opening (hereinafter referred to as a room between the living rooms 11 and the Japanese-style room 14) extends across the entire boundary area between the living room 11 and the Japanese-style room 14. Opening 22) is formed. Therefore, the LDK space 20 and the Japanese-style room 14 are continuously formed via the inter-room opening 22, thereby forming an open and spacious room space on the first floor portion.

  A staircase 19 is provided in the staircase space 18. Using this staircase 19, it is possible to move between the first floor part and the second floor part. The staircase space 18 is an atrium space extending up and down across the first floor portion and the second floor portion, and is surrounded by a partition wall. As a partition wall, a pair of facing partition walls 25 and 26 are provided on both sides of the staircase space 18. The partition wall 25 partitions the stair space 18 from the Japanese-style room 14, and the partition wall 26 partitions the stair space 18 from the dressing room 17. The staircase space 18 is partitioned from the outside by an outer wall 27, and a staircase opening 23 is formed in a partition wall (not shown) opposite to the outer wall 27 across the staircase space 18.

  The staircase opening 23 communicates the staircase space 18 with the dining room 12 (in other words, the LDK space 20), and the dining room 12 and the staircase space 18 can be moved through the staircase opening section 23. Specifically, a staircase opening 23 is formed between the end portions (end portions on the LDK space 20 side) of the partition walls 25 and 26, and is opposite to the staircase opening portion 23 with the partition wall 25 interposed therebetween. An inter-room opening 22 is provided on the side. In this case, the staircase opening 23 and the inter-room opening 22 are formed in the same plane, in other words, the openings 22 and 23 are arranged in the same straight line in plan view.

  Note that the staircase opening 23 is not provided with fittings such as sliding doors and hinged doors (specifically, permanent fittings) for opening and closing the opening 23, and therefore the LDK space 20 is staircased via the staircase opening 23. It is open to the space 18. Therefore, the feeling of opening of the LDK space 20 is further enhanced.

  Although the floor plan of the second floor is not shown, the second floor is provided with a private room such as a child room, a bedroom, and a study in addition to the second-floor room.

  By the way, in the building 10 of the present embodiment, a movable lattice partition 30 in which a plurality of vertical bars are assembled in a lattice shape (continuous shape) is provided on the first floor portion. The lattice partition 30 is movably provided in the first floor portion, and the lattice partition 30 can partition the indoor space of the first floor portion as necessary. Hereinafter, the lattice partition 30 and the surrounding configuration will be described.

  As shown in FIG. 1, a guide rail 28 for guiding the movement of the lattice partition 30 is provided on the first floor portion of the building 10. The guide rail 28 is provided on the ceiling surface of the LDK space 20, and the rail 28 is indicated by a two-dot chain line for convenience in FIG. The guide rail 28 is continuous along the boundary between the LDK space 20 and the Japanese-style room 14 (in other words, the inter-room opening 22) and the boundary between the LDK space 20 and the staircase 18 (in other words, the staircase opening 23). And a second guide rail 28b that is orthogonal to the first guide rail 28a and extends along the boundary between the living room 11 and the dining room 12. Specifically, the first guide rail 28a extends linearly across the entire boundary portion of the LDK space 20 and the Japanese-style room 14, and across the entire boundary portion of the LDK space 20 and the staircase space 18, and the second guide The rail 28 b extends in a straight line over the entire boundary portion between the living room 11 and the dining room 12. The first guide rail 28a and the second guide rail 28b are provided continuously with each other.

  The lattice partition 30 is basically suspended from the guide rail 28 with its width direction directed in the direction in which the guide rail 28 extends (details will be described below. Are supported along the rail 28 in the suspended state. When the lattice partition 30 is moved along the first guide rail 28 a, the lattice partition 30 is disposed at the boundary between the LDK space 20 and the Japanese-style room 14 (in other words, the inter-room opening 22) and partitions the spaces 14 and 20. One partition position (see FIG. 5A) and a second partition position (see FIG. 5) that is arranged at the boundary between the LDK space 20 and the staircase space 18 (in other words, the staircase opening 23) and partitions the two spaces 18, 20. (See (b)).

  Further, when the lattice partition 30 is moved along the second guide rail 28 b, the lattice partition 30 can be moved to any position at the boundary between the living room 11 and the dining room 12. In this case, the living room 11 and the dining room 12 are partitioned by the partition 30 by arranging the lattice partition 30 at the arbitrary position (third partition position (see FIG. 5C)). In addition, switching from the state moved along the first guide rail 28a (or the second guide rail 28b) to the state moved along the second guide rail 28b (or the first guide rail 28a) The rails 28a and 28b are performed through a continuous portion.

  Then, the structure of the lattice partition 30 is demonstrated based on FIG.2 and FIG.3. 2 is a front view showing the lattice partition 30 and FIG. 3 is an enlarged perspective view showing a part of the lattice partition 30. As shown in FIG. In FIG. 3, (a) shows a state where the gap between the vertical bars is opened, and (b) shows a state where the gap is closed.

  As shown in FIG. 2, the lattice partition 30 is formed in a rectangular plate shape as a whole, and its height dimension is the ceiling height of the LDK space 20 (specifically, the floor surface 47 to the ceiling surface 46 of the space 20). (Height dimension up to (see FIG. 4)), which is substantially the same, and slightly smaller than that. Further, the grid partition 30 has a lateral width (specifically, a lateral width in a state in which the gap 38 is opened as will be described later) approximately half of the opening width of the inter-room opening 22. The lattice partition 30 includes a plurality of vertical bars 31 arranged side by side at a predetermined interval (specifically, a fixed interval) and a plurality of connecting members 32 that connect adjacent vertical bars 31 to each other. Of these, the vertical rail 31 corresponds to a long material.

  As shown in FIG. 3, the vertical bar 31 has a rectangular tube shape extending vertically, and an upper plate portion 36 and a lower plate portion 37 are fixed to upper and lower end portions, respectively. Each of these members 31, 36 and 37 is made of a metal material such as aluminum and is fixed to each other by welding. A plurality of connecting members 32 are provided vertically (four in FIG. 2) between adjacent vertical bars 31, and connect the vertical bars 31 to the left and right. The connecting member 32 has a rectangular tube shape extending in the horizontal direction (the direction in which the vertical bars 31 are arranged), and the length dimension (in the horizontal direction) is the same as the horizontal width dimension of the vertical bars 31, and in particular, slightly smaller than that. It is a dimension.

  The connecting structure by the connecting member 32 will be described in detail. A plurality of openings 41 are formed in the side surface portion of each vertical rail 31, specifically the side surface portion 31 a facing the gap 38, corresponding to the installation position of the connecting member 32. ing. The opening 41 is an insertion hole into which the connecting member 32 is inserted, and communicates the inside and outside of the vertical rail 31. The opening 41 has a rectangular shape having a dimension slightly larger than the cross-sectional dimension (vertical and horizontal dimensions) of the connecting member 32, and the end of the connecting member 32 is inserted into the opening 41. That is, the connecting member 32 connects the vertical bars 31 with both ends thereof inserted into the openings 41 of the adjacent vertical bars 31 with the connecting member 32 interposed therebetween.

  More specifically, for example, a regulation plate (not shown) made of a rectangular flat plate that is slightly larger than the size (vertical and horizontal dimensions) of the opening 41 is fixed to both ends of the connecting member 32. The plate is disposed inside the vertical beam 31 in a state in which the connection member 32 is inserted into the opening 41, thereby preventing the connection member 32 from coming out of the vertical beam 31 from the opening 41.

  In such a connected state, the adjacent vertical bars 31 are movable with respect to the connecting member 32 that connects them. Specifically, each of the vertical bars 31 can be moved in the insertion direction, that is, in the left-right direction (in other words, in the horizontal width direction of the lattice partition 30) with the connecting member 32 inserted through the opening 41. . In this case, the adjacent vertical bars 31 can adjust the distance between each other, in other words, the width dimension of the gap 38 by such movement. As a result, as shown in FIG. 3A, the lattice partition 30 is shown in FIG. 3B, in which the gap between the adjacent vertical bars 31 is separated and a gap 38 is formed (opened). As described above, the adjacent vertical bars 31 are brought into contact with each other so that the gap 38 is not formed (closed) and can be switched to a gap closed state. When the lattice partition 30 is in the gap open state, ventilation is possible through the gap 38, while when the gap is closed, such ventilation is not possible.

  In addition, each connection member 32 is divided | segmented and provided for every clearance gap 38 of the lattice partition 30, and when each clearance gap of the lattice partition 30 is closed, these connection members 32 will be in the state accommodated in the inside of the vertical beam 31. FIG. Therefore, when the lattice partition 30 is in the gap closed state, the connecting member 32 does not protrude outward (side) with respect to the vertical rail 31 at both ends in the width direction of the partition 30.

  Moreover, in this lattice partition 30, the horizontal width dimension can be changed by adjusting the space | interval of the adjacent vertical bars 31 as mentioned above. In other words, the lattice partition 30 can be expanded and contracted in the width direction. From this point, it can be said that the gap opening state of the lattice partition 30 is the partition width expanded state and the gap closed state is the partition width contracted state. Specifically, the lateral width of the lattice partition 30 in the gap open state (partition width expanded state) is about twice the lateral width of the partition 30 in the gap closed state (partition width contracted state). Moreover, in this embodiment, the horizontal width of the lattice partition 30 in the gap closed state is substantially the same as the opening width of the staircase opening 23 (see FIG. 5B).

  A guide member 33 is attached to the upper ends of the two vertical bars 31 arranged at both ends of the plurality of vertical bars 31 in the lattice partition 30. The guide member 33 is disposed in a rail groove 55 (details will be described later) of the guide rail 28 and is guided along the rail 28. Hereinafter, the guide mechanism by the guide rail 28 will be described with reference to FIG. FIG. 4 is a cross-sectional view showing a state where the guide member 33 is disposed on the guide rail 28.

  As shown in FIG. 4, the guide member 33 is made of a metal material such as stainless steel, and has a disk-like fixing portion 43 fixed to the upper plate portion 36 of the vertical rail 31, and a shaft portion 44 extending upward from the fixing portion 43. And a disc-shaped guided portion 45 provided at the upper end of the shaft portion 44. The axes of the fixed portion 43 and the guided portion 45 are located on the same axis as the shaft portion 44.

  On the other hand, the guide rail 28 is made of a steel plate, and includes a fixed plate portion 51 fixed to the ceiling surface 46, a pair of hanging plate portions 52 suspended from both ends of the fixed plate portion 51, and a lower end portion of each hanging plate portion 52. And a pair of support plate portions 53 that extend toward each other. An inner space surrounded by these plate portions 51 to 53 is a rail groove 55, and the rail groove 55 is opened downward.

  Here, the guide member 33 has a guided portion 45 disposed in the rail groove 55 of the guide rail 28, and is placed on the support plate portion 53 in the disposed state. Therefore, the lattice partition 30 is basically suspended from the guide rail 28 via the guide member 33, and is moved along the guide rail 28 in the suspended state.

  Further, the lower end portion of the lattice partition 30, for example, the lower end portion of the vertical beam 31 disposed at both ends of the plurality of vertical beams 31 (more specifically, the lower surface of the lower plate portion 37) includes a rotating body 48 a such as a wheel. The caster 48 comprised by these is attached. The rotating body 48a is rotatable in a horizontal plane. The caster 48 is placed on the floor surface 47 and supports a part of the load of the lattice partition 30 from below. When the lattice partition 30 moves along the guide rail 28, the casters 48 (rotating bodies 48a) roll on the floor surface 47 accordingly, so that the lattice partition 30 can be moved smoothly.

  The caster 48 is provided with a brake 48b for stopping the rotation of the rotating body 48a. By stopping the rotation of the rotating body 48a by the brake 48b, the movement of the lattice partition 30 can be prevented. In addition, in the rotationally stopped state of the rotating body 48a, expansion and contraction of the lateral width of the lattice partition 30 is also restricted. Therefore, in this case, even when the lattice partition 30 is in any state of the gap open state (in other words, the partition width expanded state) and the gap closed state (in other words, the partition width reduced state), the state is maintained. ing. Here, the brake 48b corresponds to blocking means.

  Then, the effect | action of the lattice partition 30 mentioned above is demonstrated, referring FIG. FIG. 5 is an explanatory diagram for explaining the operation of the lattice partition 30.

  As described above, the lattice partition 30 moves along the first guide rail 28a and the second guide rail 28b, so that the first partition position shown in FIG. 5A and the second partition shown in FIG. It is possible to move to each of the partition position and the third partition position shown in FIG. The lattice partition 30 is arranged at any one of these partition positions as required and used as a partition. When the lattice partition 30 is switched between a gap open state (horizontal width expanded state) and a gap closed state (horizontal width contracted state), for example, the vertical rails 31 at both ends are pulled to the side away from each other, It is done by pushing. Here, the first partition position and the third partition position correspond to the first position, and the second partition position corresponds to the second position.

  Next, the operation at each partition position by the lattice partition 30 will be described. First, as shown to Fig.5 (a), when the lattice partition 30 exists in a 1st partition position, the same partition 30 is made into a clearance gap open state, for example. In this case, since the LDK space 20 and the Japanese-style room 14 can be partitioned while ventilating through the gap 38 of the lattice partition 30, both the partitioned spaces 14 and 20 can be made comfortable. Further, when the lattice partition 30 is in the first partition position, the partition partition 30 may be in a gap closed state. In that case, since the line of sight can be blocked by the lattice partition 30, privacy of the Japanese-style room 14 can be ensured, for example, when a customer is visiting the living room 11.

  Moreover, as shown in FIG.5 (b), when the lattice partition 30 exists in a 2nd partition position, let the same partition 30 be a clearance gap closed state. As a result, when air conditioning (specifically, heating) of the LDK space 20 is performed by the air conditioner 21, the lattice partition 30 can suppress the warm air in the LDK space 20 from flowing into the staircase space 18, so that It is possible to suppress the warm air from flowing up to the second floor through the staircase space 18. Therefore, a decrease in air conditioning efficiency can be suppressed. In addition, when the grid partition 30 is in the second partition position, entry and exit from the LDK space 20 to the staircase space 18 is blocked, so that infants, pets, etc. enter the staircase space 18 from the LDK space 20 and move up the stairs 19. There is also an advantage that it is possible to prevent such a situation.

  Moreover, as shown in FIG.5 (c), when the lattice partition 30 exists in a 3rd partition position, let the same partition 30 be a clearance gap open state, for example. In this case, since the living room 11 and the dining room 12 can be partitioned while ventilating through the gaps 38 of the lattice partition 30, the partitioned spaces 11 and 12 can be made comfortable. In such a case, the lattice partition 30 may be closed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  A grid partition 30 in which a plurality of vertical bars 31 are assembled in a grid is provided, and the first partition position (or the third partition position) that partitions the room space into the room space, and the LDK space 20 and the staircase space 18 are partitioned. It was made movable between the second partition positions. The gap 38 between the adjacent vertical bars 31 in the lattice partition 30 can be opened and closed. According to this, if the lattice partition 30 is moved to the second partition position and the partition 30 is set in the gap closed state, ventilation between the LDK space 20 and the staircase space 18 through the gap 38 can be blocked. Thereby, when heating by the air conditioner 21 is performed in the LDK space 20, the warm air in the LDK space 20 flows into the staircase space 18, and eventually flows (up) through the staircase space 18 to the second floor portion. Therefore, a decrease in air conditioning efficiency can be suppressed.

  In addition, it is possible to provide a sliding door for opening and closing the opening 23 in the staircase opening 23 and block the ventilation between the LDK space 20 and the staircase space 18 by the sliding door, but if a sliding door is installed in the staircase opening 23 If it becomes, there exists a possibility that the structure of the opening part 23 periphery may become complicated. In this regard, according to the above configuration that blocks the ventilation between the LDK space 20 and the staircase space 18 by moving the lattice partition 30 to the second partition position, the configuration around the staircase opening 23 becomes complicated. While suppressing, the fall of air-conditioning efficiency can be suppressed.

  In order to make the interval between adjacent vertical bars 31 variable, a connecting member 32 that connects the vertical bars 31 so as to be relatively displaceable is provided. Specifically, the adjacent vertical bars 31 are provided so as to be movable with respect to the connecting member 32 that connects them, and the distance between the vertical bars 31 is made variable by the movement of the vertical bars 31. Then, the gaps 38 between the vertical bars 31 are closed by bringing the adjacent vertical bars 31 into contact with each other, and the gaps 38 are opened by separating the adjacent vertical bars 31 from each other. The gap was opened. In this case, the horizontal width of the lattice partition 30 can be adjusted in size as the gap 38 is opened and closed. Specifically, when the gap 38 is opened (formed), the lateral width of the lattice partition 30 can be increased, and when the gap 38 is closed (not formed), the lateral width of the lattice partition 30 is decreased. be able to. Accordingly, when the interstitial partition 30 is arranged at the first partition position to partition the LDK space 20 and the Japanese-style room 14, the spaces 14 and 20 can be partitioned over a wide range. On the other hand, when the stair space 18 and the LDK space 20 are partitioned by disposing the lattice partition 30 at the second partition position and closing the gap, the amount of the lattice partition 30 protruding sideways from the stair opening 23 is reduced. Inconveniences such as the protruding portion hindering walking can be suppressed. Therefore, in this case, the lattice partition 30 can be suitably used both when the LDK space 20 and the Japanese-style room 14 are partitioned and when the LDK space 20 and the staircase space 18 are partitioned.

  Since the guide rails 28 for guiding the movement of the lattice partitions 30 are provided, the movement of the lattice partitions 30 can be suitably performed.

  Since the brake 48b is provided in the caster 48 as a blocking means for preventing the movement of the lattice partition 30, the lattice partition 30 can be held at a predetermined position by stopping the rotation of the rotating body 48a by the brake 48b. Thereby, even if it is the movable lattice partition 30, the stable installation state is realizable.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the gap 38 between adjacent vertical bars 31 in the lattice partition 30 is opened and closed by adjusting the interval between the vertical bars 31 by relatively displacing the vertical bars 31 with each other. However, the configuration for opening and closing the gap 38 is not necessarily limited to this. For example, the configuration shown in FIG. 6 can be considered. The lattice partition 50 shown in FIG. 6 includes two partition panels 60a and 60b having the same configuration. Each of the partition panels 60a and 60b is provided so as to be movable in the horizontal width direction in a state where at least a part thereof is overlapped, and the overlap margin is adjusted by the movement. The partition panels 60a and 60b include a plurality of vertical bars 61a and 61b provided side by side and a plurality of connecting members 62a and 62b that connect the adjacent vertical bars 61a and 61b to each other. The configuration is the same as that of the lattice partition 30. In the partition panels 60a and 60b, the difference from the lattice partition 30 is that both end portions of the connecting members 62a and 62b are fixed to the adjacent vertical bars 61a and 61b, respectively. The interval of is assumed to be unchanged. However, as in the case of the lattice partition 30, the interval between the vertical bars 61a and 61b may be variable. Another difference is that the partition panels 60 a and 60 b have a thickness that is approximately half the thickness of the lattice partition 30. Therefore, the lattice partition 50 has the same thickness as the lattice partition 30.

  According to the lattice partition 50 having such a configuration, as shown in FIG. 6A, in the partition panels 60a and 60b, the vertical bars 61a and 61b overlap each other in the thickness direction of the lattice partition 50. Then, the gap 38 between the vertical bars 61 a and 61 b in the partition panels 60 a and 60 b is continued in the thickness direction of the lattice partition 50. In this case, air can be circulated through the continuous gap 38. On the other hand, as shown in FIG. 6B, in the partition panels 60a and 60b, in the state where the vertical bars 61a and 61b are alternately arranged, the vertical bars 61a ( 61b) The gap 38 between the two is closed by the vertical rail 61b (61a) of the other partition panel 60b (60a). In this case, the air flow through the lattice partition 50 is blocked.

  That is, according to the lattice partition 50 described above, the position of one partition panel 60a (60b) of each partition panel 60a, 60b is slightly shifted with respect to the other partition panel 60b (60a). Each gap 38 of the other partition panel 60b can be opened and closed at a time by simply shifting the vertical bars 61a and 61b by the horizontal width. In this case, the opening / closing operation of the gaps 38 can be facilitated as compared with the case where the gaps 38 of the lattice partition 50 (specifically, the partition panel 60) are individually opened / closed.

  In this example, as shown in FIG. 7, two guide rails 65a and 65b are provided on the first floor portion of the building 10 to guide the movement of the partition panels 60a and 60b, respectively. , 60b are moved independently of each other along the guide rails 65a, 65b. In FIG. 7, the partition panels 60 a and 60 b are arranged in a state where the boundary portions between the LDK space 20 and the Japanese-style room 14, that is, the end portions in the width direction are overlapped at the first partition position. In this case, since each partition panel 60 is disposed over the entire area of the boundary portion (the entire opening width of the inter-room opening 22), the independence of both spaces 20 and 14 partitioned by the same partition 60 can be improved. it can.

  (2) Further, the lattice partition 30 may be provided with an opening / closing plate as an opening / closing means for opening / closing the gap 38 between the vertical bars 31. The open / close plate is formed of, for example, a long flat plate extending along the vertical rail 31 and has a length and a width capable of closing the gap 38. The open / close plate is rotatably attached to the side surface of each vertical rail 31 (specifically, the side surface orthogonal to the side surface 31a) via a rotation member such as a hinge. In this case, by opening the opening / closing plate, the gap 38 can be opened, and when the opening / closing plate is closed, the gap 38 can be closed. .

  (3) In the above embodiment, the lattice partition 30 is formed in a lattice shape (continuous shape) by a plurality of vertical bars 31 (corresponding to a long material). It may be formed in a lattice shape by an equivalent to a scale material. That is, a lattice partition may be formed by arranging a plurality of horizontal rails vertically. In this case, it is conceivable that the opening / closing of the gap between the adjacent horizontal rails is configured using the opening / closing plate in (2) above. In addition, the lattice partition may be formed in a lattice shape by a plurality of vertical bars and a plurality of horizontal bars. In this case, a portion surrounded by the vertical rail and the horizontal rail becomes a gap, and it is conceivable that the gap is opened and closed by the opening / closing plate as described above.

  (4) You may comprise the connection member 32 so that expansion-contraction is possible. In the lattice partition 70 shown in FIG. 8, an extendable connecting member 71 is used instead of the connecting member 32 in the above embodiment. The connecting member 71 includes a pair of first connecting portions 72 and a second connecting portion 73 that connects the first connecting portions 72 to each other. The first connecting portion 72 has a rectangular tube shape extending in the horizontal direction, and its length is substantially half the horizontal width of the vertical rail 31. On the other hand, the second connecting portion 73 has a rectangular cylindrical shape extending in the horizontal direction, like the first connecting portion 72, and its length is substantially the same as the horizontal width of the vertical rail 31. The second connecting portion 73 has a cross-sectional dimension (cross-sectional outer dimension) slightly smaller than the inner dimension of the first connecting portion 72.

  Both end sides of the second connecting portion 73 are inserted inside the first connecting portions 72, respectively. In other words, the second connecting portion 73 is inserted inside each first connecting portion 72, and each first connecting portion 72 is movably connected to the second connecting portion 73 in such an inserted state. Yes. Specifically, each first connecting portion 72 is movable with respect to the second connecting portion 73 in the extending direction of the connecting portion 73. In this case, the connecting member 71 can be expanded and contracted by moving the first connecting portions 72 to the sides close to or away from each other. In this example, the length of the member 71 when the connecting member 71 is extended (see FIG. 8A) is the same as the length of the member 71 when the connecting member 71 is contracted (see FIG. 8B). It is about twice as large as the horizontal width of the vertical rail 31.

  Although not shown, the connecting member 71 is provided with a detachment preventing structure for preventing the first linking portion 72 from detaching from the second linking portion 73. As such a structure, for example, an engaging portion (not shown) protruding from the inner peripheral surface is provided on the inner peripheral surface of the first connecting portion 72, while the outer peripheral surface of the second connecting portion 73 protrudes from the outer peripheral surface. By providing an engaged portion (not shown) and engaging the engaging portion of the first connecting portion 72 with the engaged portion of the second connecting portion 73, the first connecting portion 72 is separated from the second connecting portion 73. A configuration for preventing separation can be considered.

  The connecting member 71 having the above configuration is disposed between the adjacent vertical bars 31 to connect the vertical bars 31 to each other. Specifically, each first connecting portion 72 of the connecting member 71 is connected to each vertical rail 31. Note that the connecting member 71 (specifically, the first connecting portion 72) is movably connected to the vertical rail 31 in the same manner as the connecting member 32 of the above embodiment.

  According to the lattice partition 70, in a state where the connecting member 71 is contracted, the gaps 38 can be closed by bringing the adjacent vertical bars 31 into contact with each other, and the gaps 38 are separated by separating the vertical bars 31 from each other. Can be opened (see FIG. 8B). About this point, it is the same as that of the lattice partition 30 of the said embodiment. And in this lattice partition 70, the clearance gap 38 can be enlarged further by extending the connection member 71 from the clearance open state (state of FIG.8 (b)) in the state which shortened the connection member 71 (FIG. 8). (See (a)). In short, in the lattice partition 70, the interval between the vertical bars 31 can be adjusted by sliding the adjacent vertical bars 31 with respect to the connecting member 71 or by extending or contracting the connecting member 71. Therefore, the adjustment range of the interval between the vertical bars 31 can be increased, and as a result, the adjustment range of the horizontal width of the lattice partition 70 can be increased. Thereby, when the lattice partition 70 is arranged at the first partition position and the gap is opened, the LDK space 20 and the Japanese-style room 14 can be partitioned in a wider range.

  Further, by increasing the adjustment range of the interval between the adjacent vertical bars 31, the adjustment range of the amount of air flowing through the gap 38 between the vertical bars 31, that is, the air flow rate can be increased. Therefore, there is also an advantage that various ventilation can be performed.

  Note that, in the configuration in which the connecting member 71 can be expanded and contracted, the adjacent vertical bars 31 may be fixed to the connecting member 71 so as not to move. Even in this case, the gap 38 can be opened and closed by expanding and contracting the connecting member 71.

  (5) Instead of providing the casters 48 at the lower end of the lattice partition 30, the partition partition 30 may be suspended and supported on the guide rail 28 via the guide member 33. In this case, the lattice partition 30 is suspended from the guide rail 28 with the lower end thereof being separated from the floor surface 47. Here, in such a configuration, the blocking means for blocking the movement of the lattice partition 30 may be configured as shown in FIG. 9, for example. In FIG. 9, a part of the connecting members 32 a arranged at the lower end of the connecting members 32 provided in the vertical direction in the lattice partition 30 is slidable downward. Specifically, the lower end side of the opening 41 corresponding to the connecting member 32 a in the vertical beam 31 is opened, so that the connecting member 32 a can move below the lower end of the vertical beam 31.

  Further, ratchet grooves (not shown) are formed on the side edges (both side edges) of the opening 41, and the ratchet teeth (which can be locked to the ratchet grooves) on the side surfaces (both side surfaces) of the connecting member 32a. (Not shown) is provided. Therefore, the connecting member 32a can be fixed at a predetermined slide position by locking the ratchet teeth in the ratchet groove.

  A rubber plate 81 is attached to the lower surface of the connecting member 32a by bonding or the like. Here, the rubber plate 81, the connecting member 32a and the like constitute blocking means. In this case, by moving the connecting member 32a downward, the rubber plate 81 is pressed against the floor surface 47, and in this pressed state, the connecting member 32a is fixed to the vertical rail 31 (by the ratchet engagement), thereby the lattice partition 30. Can be prevented from moving.

  (6) A partition drive device that is driven to move the lattice partition 30 may be provided, and the lattice partition 30 may be moved by driving the drive device. The partition drive device is configured by, for example, a known electric motor. In this case, the moving operation of the partition 30 can be facilitated as compared with the case where the lattice partition 30 is moved by pushing it manually.

  Moreover, you may provide the vertical beam drive apparatus which drives the movement to the horizontal direction (width direction of the lattice partition 30) about each vertical beam 31 of the lattice partition 30. FIG. The vertical beam driving device is composed of, for example, a known electric motor. In this case, by driving the vertical beam driving device, the lattice partition 30 is divided into a gap open state in which a gap 38 is formed between adjacent vertical beams 31 and a gap closed state in which the gap 38 is not formed. Can be switched. Therefore, the operation | work which switches the lattice partition 30 to each state can be made easy.

  Moreover, you may provide the control means which controls a vertical beam drive device so that the lattice partition 30 may be switched to a gap open state and a gap closed state based on whether the air conditioner 21 is operating. Specifically, when the air conditioner 21 is operating, the vertical partition driving device is set so that the lattice partition 30 is closed, and when the air conditioner 21 is not operating, the lattice partition 30 is opened. It is conceivable to control. According to this, when air conditioning is performed in the LDK space 20, the lattice partition 30 is automatically switched to the gap closed state, so that the air in the LDK space 20 flows out to the staircase space 18 using the lattice partition 30. It is convenient to suppress this.

  Further, when the air conditioner 21 is operating, the partition drive device may be driven and controlled to move the lattice partition 30 to the second partition position that partitions the stair space 18 and the LDK space 20. Then, when the air conditioning is performed in the LDK space 20, the lattice partition 30 is automatically moved to the second partition position, so that the convenience can be further enhanced.

  (7) By the way, a central type air conditioning system that performs air conditioning of a plurality of rooms on the first floor using a common air conditioner is known. When such an air conditioning system is adopted in the building 10 of the above-described embodiment, air conditioning (cooling or heating) is performed so that each living room of the living room 11, the dining room 12, and the Japanese-style room 14 that can be partitioned by the lattice partition 30 is included as an air conditioning target. You may go. That is, a blow-out grill (blow-out opening) is installed in each of the living room 11, the dining room 12, and the Japanese-style room 14, and conditioned air (cold air or warm air) is supplied to each blow-out grill from a common air conditioner. By doing so, air-conditioned air can be supplied from the air conditioner to each of the living room 11, the dining room 12, and the Japanese-style room 14 regardless of how the room space on the first floor is partitioned by the lattice partition 30. Can be suitably performed.

  (8) By the way, the unit type building comprised by connecting the several building unit which has a beam and a pillar mutually is known conventionally. Therefore, it is conceivable to apply the partition structure of the present invention to such a unit type building. The building unit has a substantially rectangular parallelepiped shape as a whole, and includes columns erected at the four corners, a ceiling beam connecting the upper ends of each column, and a floor beam connecting the lower ends of each column. . A plurality of ceiling beams are bridged between the facing ceiling beams, and the ceiling surface material is supported by the ceiling beams. On the other hand, a plurality of floor beams are bridged between opposing floor beams, and the floor material is supported by the floor beams. Here, when the guide rail 28 is installed in a unit type building, it is assumed that the rail 28 is installed across a plurality of building units. In this case, the guide rail 28 may be attached to the ceiling surface material of each building unit at the construction site.

  In the unit type building, a predetermined gap is formed between the ceiling members of the adjacent building units. In this gap, a ceiling connecting face material that connects these ceiling face materials is disposed at the construction site. Therefore, the guide rails 28 may be assembled in advance to the ceiling connecting face material in the manufacturing factory. If it does so, since installation of a guide rail can be performed simultaneously with installation of a ceiling joint surface material, reduction of a construction man-hour can be aimed at.

  (9) You may apply the partition structure of this invention to the 2nd floor part of a building. For example, in the second floor portion, a second-floor room and a staircase space 18 in which a staircase 19 leading to the first floor portion is installed are provided adjacent to each other. In this case, it is conceivable to provide the lattice partition 30 so as to be movable between a first position that partitions the second-floor room and a second position that partitions the second-floor room and the staircase space 18. Even in such a configuration, if the lattice partition 30 is moved to the second position and the partition partition 30 is closed, the air flow between the second-floor room and the staircase space 18 can be blocked. Therefore, when cooling is performed by the air conditioner in the second-floor room, it is possible to suppress the cool air in the second-floor room from flowing down (lowering) through the staircase space 18 to the first floor portion. Therefore, a decrease in air conditioning efficiency can be suppressed.
