Description

  The present invention relates to a movable partition device used mainly for partitioning indoor space of a house.

  In recent years, when it is important to extend the lifespan of homes, interior systems that can flexibly respond to changes in the lifestyles and life stages of residents by changing the interior space in a flexible manner as well as increasing the durability of structural housings, etc. It has been demanded. In constructing such an interior system, a movable partition device that can partition an indoor space with a partition wall in accordance with the use situation is used.

  As this type of movable partition device, when a plurality of partition walls partitioning the indoor space are movable and rotatable between the guide rails provided on the ceiling surface and the floor surface and do not partition the indoor space, Some partition walls can be accommodated by overlapping each other at the wall (see, for example, Patent Document 1).

  In addition, when the plurality of partition walls that partition the indoor space are movable along the guide rails provided on the ceiling surface, and when the indoor space is not partitioned, the plurality of partition walls are covered with the wall that faces the indoor space. There are some which can be accommodated in the accommodating space (see, for example, Patent Document 2).

JP-A-10-140920 JP-A-9-184357

  However, in the movable partition device described in Patent Document 1, since the plurality of partition walls are accommodated so as to be exposed so as to protrude from the walls of the indoor space, the appearance of the indoor space is accommodated when the partition walls are accommodated. In addition to this, there is a problem in that the partition wall protrudes in the indoor space and gets in the way.

  On the other hand, in the movable partition device described in Patent Document 2, the partition wall can be housed in an attractive manner so as not to get in the way in the housing space formed by covering the wall. However, when the partition walls are accommodated, the partition walls in the indoor space are guided into the accommodation space in a state perpendicular to the walls along the guide rails, and are moved in parallel with the walls in the accommodation space and overlap each other. They are housed together.

  Thus, in order to form an accommodation space that accommodates a plurality of partition walls in a state orthogonal to the wall, the wall needs to be largely swollen, and the floor area is particularly limited, and a deep space is required. In narrow houses and apartment buildings that are difficult to secure, there is a large business trip to the interior space where there is no other use, and this bulge becomes a dead space that hinders effective use of the interior space. There was a problem of pressing.

  Therefore, the present invention solves the above-mentioned problems, can reduce the dead space and effectively use the indoor space while accommodating the partition wall in an attractive manner so as not to interfere with the accommodation space, and also has a structure. An object of the present invention is to provide a movable partition device that is simple and excellent in the operability of the partition wall.

In order to solve the above problems, the movable partition device according to the present invention includes a ceiling rail 5 provided over the ceiling surface 2 of the indoor space 1 and the ceiling surface 4 of the accommodating space 3 , and the floor surface 6 of the indoor space 1 and the accommodating space. A floor rail 8 provided across the floor surface 7 of the space 3 and a partitioning posture and a storage space that are movably attached between the ceiling rail 5 and the floor rail 8 to partition the indoor space 1. And a plurality of partition walls 10 that are switchable between the housing postures accommodated in the housing 3, and the partition walls 10 protrude from substantially the center of the upper end of the wall body 31 and are guided to the ceiling rail 5 so as to be movable. A first protrusion 32 and a second protrusion 33 that protrudes from substantially the center of the lower end of the wall body 31 and is movably guided to the floor rail 8. The wall body 31 includes a first protrusion 32 and a second protrusion. 33 is rotatable around the accommodation space Is a horizontally long space formed between the inner and outer wall members 12 and 13 constituting the wall 11 facing the indoor space 1, ie, the wall 11 facing the indoor space 1. The wall main body 31 is accommodated side by side along the wall 11 in a state of being arranged on a substantially straight line so as to be substantially parallel to the wall materials 12 and 13 .

  Specifically, the ceiling rail 5 and the floor rail 8 are connected so that the rail portions 19 and 27 on the accommodation space 3 side along the wall 11 are substantially orthogonal to the rail portions 18 and 26 on the indoor space 1 side. ing.

Further, the rail portions 19 and 27 on the accommodation space 3 side in the ceiling rail 5 and the floor rail 8 are formed in a plurality of rows at intervals in the thickness direction of the wall 11 (the direction of the wall) .

Further, an opening 14 for inserting and removing the partition wall 10 with respect to the accommodation space 3 is formed in the wall 11, and an opening / closing door 15 for opening and closing the opening 14 is provided in the wall 11.

Moreover, the partition wall 10 is provided with a plurality of casters 34 at the lower end of the wall main body 31, and the casters 34 can run on the floor rail 8 at a rotational position along the floor rail 8 of the wall main body 31. The caster 34 can travel on the floor surface 6 at a rotational position shifted from the floor rail 8 of the main body 31.

  In the movable partition device according to the present invention, when the indoor space is not partitioned, the partition wall can be housed in an attractive manner so as not to obstruct the partition space. Moreover, since the partition walls are accommodated side by side along the walls in the accommodation space, it is only necessary to secure the depth of the accommodation space slightly wider than the thickness of the partition wall. We can suppress wall puffing small. As a result, since the wall thickness is slightly increased, no extra bulging occurs in the indoor space, the dead space can be reduced, the indoor space can be effectively used, and the degree of freedom of the interior plan can be increased.

  Further, since the wall body is rotatable about the first and second protrusions protruding from the substantially upper center and the lower end of the wall body, the wall body is rotatable in front of the housing space, for example. By simply rotating the main body and changing the direction along the wall, and pushing it into the accommodation space in this state and sliding it along the wall, it can be easily accommodated in the accommodation space. Thereby, the operability at the time of switching the partition wall between the partitioning posture and the housing posture can be improved, and the structure of the ceiling rail and the floor rail is changed to the rail portion on the indoor space side and the rail portion on the housing space side. It can be set as the simple structure which connected only so that it might orthogonally cross.

  Further, by forming a plurality of rows of rail portions on the storage space side of the ceiling rail and the floor rail, it is possible to accommodate many partition walls, which is effective when the number of partition walls is large.

  Furthermore, by closing the open / close door provided on the wall, the partition wall in the accommodation space becomes invisible from the indoor space side, and the appearance can be improved.

  Furthermore, a caster is attached to the lower end portion of the wall body of the partition wall, and the caster travels on the rail portion or the floor surface when the partition wall is moved or rotated, so that the partition wall is smoothly moved and rotated. The operability can be further enhanced.

When in the rotational position, the casters 34... Can run on the floor rail 8, and when the wall body 31 is in the rotational position shifted from the floor rail 8, the casters 34. ing.

  Next, the posture switching operation of the partition wall 10 in the movable partition device having the above configuration will be described.

  First, when the partition walls 10... Are in a partitioning posture for partitioning the indoor space 1, as shown in FIG. 6, the slide member 51 of the first protrusion 32 in each partition wall 10 serves as the indoor space 1 of the ceiling rail 5. The pin 72 of the second protrusion 33 is slidably inserted into the rail portion 26 on the indoor space 1 side of the floor rail 8, as shown in FIG. Further, as shown in FIG. 10, the balls 83 of the casters 34 are fitted between the upper end edges of the rail portion 26 so as to be able to roll, and the wall body 31 of the partition wall 10 extends along the upper and lower rail portions 18 and 26. Thus, it is in the state straddling between these rail parts 18 and 26.

  In this state, the partition wall 10 is lightly pushed along the upper and lower rail portions 18, 26, whereby the slide member 51 of the first projection 32 slides inside the rail portion 18, and the pin 72 of the second projection 33 is The casters 34... Run on the rail portion 26 while sliding in the portion 26, and the partition wall 10 moves along the rail portions 18 and 26. At this time, the slide member 51 slides smoothly on the rail portion 18 and the wall body 31 is supported in a balanced manner by the plurality of casters 34... be able to.

  When the partition wall 10 is moved to the front of the accommodation space 3, the first protrusion 32 and the second protrusion 32 are arranged so that the wall body 31 of the partition wall 10 is substantially parallel to the wall 11 as shown in FIG. The projection 33 is rotated about 90 degrees. At this time, as shown in FIG. 12, the slide member 51 of the first protrusion 32 is accommodated in the rail portion 18, and the pin 72 of the second protrusion 33 is accommodated in the rail portion 26 as shown in FIG. The balls 83 of the casters 34 ride on the floor surface 6 and roll on the floor surface 6. Also at this time, since the slide member 51 is tightly accommodated in the rail portion 18 and the wall body 31 is supported in a balanced manner by the plurality of high-precision casters 34..., A light force can be obtained without rattling the partition wall 10. Can be rotated smoothly. In addition, by enabling such a smooth rotation, there is no problem that the floor surface 6 is damaged by the traveling of the casters 34.

  In this way, the partition wall 10 obtained by rotating the wall body 31 by 90 degrees is pressed lightly along the upper and lower rail portions 18 and 26 to open the partition wall 10 through the opening 14 opened by opening the door 15. Is moved into the accommodation space 3. Also at this time, the caster 34... Runs on the floor surface 6 while the slide member 51 of the first protrusion 32 slides in the rail portion 18 and the pin 72 of the second protrusion 33 slides in the rail portion 26. Therefore, the partition wall 10 can be moved smoothly with a light force without rattling, and the floor surface 6 is not damaged by the running of the casters 34.

  In this way, the partition wall 10 is pushed into the housing space 3, and the slide member 51 of the first protrusion 32 is guided to the rail portion 19 on the housing space 3 side that is continuous with the rail portion 18 on the indoor space 1 side. 2 When the pin 72 of the projection 33 is guided to the rail portion 27 on the housing space 3 side that is continuous with the rail portion 26 on the indoor space 1 side, the partition wall 10 is moved along the upper and lower rail portions 19 and 27, that is, horizontally long. Slide along the storage space 3. At this time, as shown in FIG. 8, in the state where the rail members 24, 24 of the rail portion 19 are engaged with the engaging grooves 58, 58 of the slide member 51 of the first protrusion 32, the slide member 51 is in its short direction. 7, while the pin 72 of the second protrusion 33 slides on the rail portion 27, as shown in FIG. 7, the casters 34. Drive on. As a result, the slide member 51 can be smoothly slid with a light force without causing the partition wall 10 to rattle without rotating within the rail portion 19.

  Then, by repeating such an operation, the partition walls 10... Are accommodated side by side in the accommodation space 3, and when all the partition walls 10 .. are accommodated, the open / close door 15 is closed and the partition walls 10 are separated from the indoor space 1.・ Do not see. In the housing posture of the partition wall 10..., The wall body 31 of the partition wall 10 faces the wall members 12 and 13 of the wall 11, and the partition wall 10. Are arranged in a substantially straight line. In addition, what is necessary is just to perform said operation | movement reversely in order to change the partition wall 10 ... from the accommodation attitude | position to a partition attitude | position.

  Thus, in the movable partition device having the above-described configuration, the partition wall 10 can be housed in the housing space 3 formed by covering the wall 11 with good appearance so as not to get in the way. In addition, since the partition walls 10 are accommodated side by side along the wall 11 in the storage space 3, the depth of the storage space 3 only needs to be secured slightly wider than the thickness of the partition wall 10, and thus is stored. The wiping of the wall 11 when forming the space 3 can be kept small. As a result, the thickness of the wall 11 is slightly increased, so that no extra bulging occurs in the indoor space 1, the dead space can be reduced and the indoor space 1 can be effectively used, and the degree of freedom of the interior plan is increased. Can do.

  Furthermore, since the partition wall 10 and the wall main body 31 can rotate centering on the 1st protrusion 32 and the 2nd protrusion 33 which protruded from the upper end part approximate center and lower end part approximate center of the wall main body 31, For example, the wall main body 31 is rotated in front of the accommodation space 3 to change the direction along the wall 11. In this state, the wall body 31 is easily pushed into the accommodation space 3 and slid along the wall 11. Can be accommodated. Thereby, the operability at the time of switching the partition wall 10 between the partitioning posture and the housing posture can be improved, and the structure of the ceiling rail 5 and the floor rail 8 is changed to the rail portion 18 on the indoor space 1 side. , 26 and the rail portions 19 and 27 on the housing space 3 side are simply connected so as to be substantially orthogonal to each other.

  Further, a caster 34 is attached to the lower end portion of the wall body 31 of the partition wall 10... So that the caster 34. 6, the partition wall 10 can be moved and rotated smoothly and stably, and the operability can be further improved.

  In many cases, the partition wall is of a type that moves by engaging a pair of protrusions protruding from both ends of the upper end of the wall body with the rail. Therefore, when switching the partition wall between the partitioning posture and the housing posture, complicated operations are required and the structure of the rail becomes complicated. Improvement and simplification of the structure cannot be achieved.

  The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention.

  For example, in the above embodiment, the ceiling rail 5 and the floor rail 8 are generally formed in a substantially T shape, but may be formed in a generally L shape as a whole.

Further, as shown in FIGS. 14 and 15, rails 19 and 27 on the side of the accommodation space 3 are formed in two rows at intervals in the thickness direction of the wall 11 (the direction of the wall) , and these are formed on the indoor space 1 side. It is good also as a structure connected by the connection rail parts 90 and 91 arrange | positioned on the extension of the rail parts 18 and 26 of this. As a result, as shown in FIG. 16, the partition walls 10... Can be arranged in two rows at intervals in the wall covering direction in the accommodating space 3, which is effective when the number of the partition walls 10. It is.
