Description

  The present invention relates to a movable partition guide rail suitable for a movable partition that partitions a room.

  Traditionally, movable partitions are installed in large spaces in the building, and the rooms are divided into spaces that are sized according to the number of people attending meetings and events. It is used for partitioning or partitioning a part of the room for other purposes such as for children or a storage room.

  Such a movable partition assumes a position to be partitioned in advance, and a movable partition guide rail (hereinafter simply referred to as a guide rail) is installed on the ceiling over the moving area of the sliding door. A plurality of sliding doors suspended from the rails are gathered or stored in one place in the room, and are drawn out along the guide rail as necessary to partition the room.

  As such a conventional movable partition, a first rail and a second rail as guide rails (upper rails) are arranged at right angles on the ceiling of the room, and a plurality of rails are provided on each of the rails in the partition state in which the room is partitioned. There is a configuration in which sliding doors are arranged in series (for example, see Patent Document 1).

  In addition, as a conventional movable partition, there are a plurality of mutually parallel vertical rails arranged as guide rails on the ceiling of the room, and a plurality of mutually parallel horizontal rails arranged adjacently. Are arranged at right angles, and there is a configuration in which one sliding door is arranged on each vertical rail and each horizontal rail (see, for example, Patent Document 2).

  By the way, in the conventional movable partition, when a sliding door, a suspension vehicle, etc. are damaged for some reason, the maintenance which replaces the damaged sliding door, a suspension vehicle, etc. with a new sliding door, a suspension vehicle, etc. is performed.

Japanese Utility Model Publication No. 6-67321 Japanese Patent Laid-Open No. 10-231654

  However, when exchanging sliding doors, suspension vehicles, etc. in the conventional movable partition, in order to detach the sliding door from the guide rail, it is necessary to remove the guide rail installed on the ceiling from the ceiling and then attach it again. The rail is long and has a considerable weight, and there is a problem that it takes time to attach and detach the guide rail.

  Therefore, there is a demand for a movable partition guide rail that can easily perform maintenance such as replacement of a sliding door and a suspended vehicle.

  The present invention has been made in view of these points, and an object thereof is to provide a movable partition guide rail that can easily perform maintenance such as replacement of a sliding door.

  In order to achieve the above object, the present invention is a movable partition guide rail installed on a ceiling for partitioning a room and capable of being movably suspended via a suspension car, which can be opened and closed. A pair of plate-like top plates that can be attached to each other and a pair of parallel plate-like plates extending perpendicularly downward from each of both end edges in the width direction perpendicular to the longitudinal direction of the top plate portion. A main body rail, and an end rail shorter than the main body rail formed in the same cross-sectional shape as the main body rail that is detachably attached to the ceiling and arranged in series at least at one end of the main body rail; There is provided a guide rail for a movable partition, characterized in that it has connecting means for connecting and releasing the main body rail and the end rail.

  In the present invention, the connecting means is movable inside the main body rail and the end rail, and includes a slide plate having a long hole formed along a moving direction, and a moving space of the slide plate. In order to form on the inner surface side of the top plate portion of each of the main body rail and the end rail, from the inner surface of the pair of side plate portions provided on each of the main body rail and the end rail, respectively. A pair of flat slide guides that protrude in a right angle toward the top, extend in parallel with the top plate portion at a distance, and are opposed to each other at a distance from the top plate portion; the main body rail; A first fixing screw that is screwed to the top plate portion of the main body rail through the elongated hole and a top plate portion of the end rail to be coupled to the end rail. The second fixing screw It may be configured to have. Accordingly, the first fixing screw is screwed to the top plate portion of the main body rail through the long hole, and the second fixing screw is screwed to the top plate portion of the end rail through the long hole. Thus, the main body rail and the end rail can be connected. Further, by removing at least one of the first fixing screw screwed to the top plate portion of the main body rail or the second fixing screw screwed to the top plate portion of the end rail, the main body rail and the end portion are removed. The connection with the rail can be released. Therefore, it is possible to easily connect and release the main body rail and the end rail. In addition, since the connecting means can be arranged inside the guide rail, it is possible to reduce a sense of discomfort in appearance in an open state where the room is not partitioned.

  In the present invention, the effective length dimension along the moving direction of the slide plate through which the first fixing screw and the second fixing screw of the elongated hole can be inserted is the first length formed on the top plate portion of the main body rail. It is equal to or longer than the distance between the centers of the first screw hole into which the one fixing screw is screwed and the second screw hole into which the second fixing screw formed in the top plate portion of the end rail is screwed. It can be set as the formed structure. As a result, the slide plate can be moved inside the end rail movement space by loosening the second fixing screw or the first fixing screw remaining on the top plate portion with the first fixing screw or the second fixing screw removed. It can be slid into the moving space of the main body rail. In other words, the slide plate can be caused to appear and disappear in the movement space of the main body rail or the movement space of the end rail while being held by the main body rail or the end rail. As a result, when attaching / detaching the end rail to / from the ceiling, the slide plate can be stored in the movement space of the main body rail or the movement space of the end rail. The end rails installed on the ceiling can be easily attached and detached.

  In the present invention, both the main body rail and the end rail may be formed of an aluminum alloy molding material, and the slide plate may be formed of an aluminum alloy plate material. Thereby, compared with the case where steel materials, such as stainless steel, are used, weight reduction can be achieved easily. Moreover, since both the main body rail and the end rail can be formed by one molding die, the die cost can be reduced. That is, a long rail can be formed by one molding die, and the main body rail 11 and the end rail 12 can be obtained from this long rail.

  According to the movable partition guide rail of the present invention, the end rail can be easily removed from the ceiling by a simple method of releasing the connection between the main body rail and the end rail by the connecting means. It provides excellent effects such as easy maintenance.

  The movable partition of this embodiment has illustrated the thing which accommodates a some sliding door in a door pocket in the open state which does not partition a room.

  As shown in FIGS. 1 to 4, the movable partition 1 of the present embodiment is a movable partition guide rail 2 (hereinafter simply referred to as a guide rail) that is detachably installed on the ceiling R to partition a room. A plurality of sliding doors 4 movably suspended on a guide rail 2 via a suspension wheel 3 and capable of opening and closing, in the present embodiment, five sliding doors 4 and five sliding doors 4 in an open state without partitioning a room. It has a door pocket 5 for storage.

  The guide rail 2 of the present embodiment is formed of a molding material of an aluminum alloy, and an end rail 12 arranged in series with a main body rail 11 and a free end as one end of the main body rail 11 shown in FIG. And have. The main body rail 11 and the end rail 12 are connected and integrated by connecting means 13 described later. A storage rail 14 used for storing the sliding door 4 in the door pocket 5 is disposed at the other end of the main body rail 11 shown at the lower right end in FIG.

  The main body rail 11 of the present embodiment includes a first rail 16 formed in a straight line extending in the up-down direction in FIG. 2 and a second rail 17 formed in a straight line extending in the left-right direction in FIG. have. The first rail 16 and the second rail 17 are connected to each other at a right angle, and are formed as a single plane L-shaped rail as a whole.

  In addition, as the main body rail 11, in the case of the movable partition of the structure which partitions off between the wall surfaces which mutually oppose a room, what was used as the linear one rail is used.

  The end rail 12 is disposed at the end of the guide rail 2 farthest from the door pocket 5, that is, at the free end portion of the first rail 16. The end rail 12 is formed in the same cross-sectional shape as the main body rail 11. Here, “the same cross-sectional shape as the main body rail 11” means that the cross-sectional shape in the width direction orthogonal to the length direction of the end rail 12 is a width direction orthogonal to the length direction of the main body rail 11. This is the same as the cross-sectional shape (see FIG. 5). Further, the end rail 12 has a length dimension RL shown in the vertical direction of FIG. 2 of, for example, about 150 to 250 mm, and in this embodiment, 200 mm. That is, the end rail 12 is formed to be shorter in length than the main body rail 11. Further, the end rail 12 is connected to the main body rail 11 installed on the ceiling R as shown by a two-dot chain line in FIGS. Are formed so as to be individually removable from the ceiling R. Then, by removing the end rail 12 from the ceiling R, all the sliding doors 4 together with the suspension wheel 3 from the guide rail 2 can be sequentially removed from the wall surface PA side.

  The storage rail 14 is for storing the five sliding doors 4 in the door pocket 5 and extends linearly from the other end which is the free end portion of the second rail 1711 shown on the right side of FIG. The linear pull-in rail 14a arranged along the opening of the door pocket 5 and a pair of straight branch rails 14b branched from the pull-in rail 14a toward the inside of the door pocket 5 at right angles. ing. Instead of the storage rail 14, a collective rail for stacking five sliding doors 4 on the wall surface may be used.

  As described above, the first rail 16 and the second rail 17 constituting the main body rail 11, the end rail 12, the pull-in rail 14a constituting the storage rail 14 and the pair of branch rails 14b are respectively in the longitudinal direction. The cross-sectional shapes in the width direction perpendicular to the cross section are all the same.

  As shown in FIG. 5, the guide rail 2 of this embodiment (reference numeral 2 is a general term for the main body rail 11, the end rail 12 and the storage rail 14) is such that the lower end surface of the guide rail 2 is very slightly from the ceiling R. Is attached to a rail groove RA recessed in the ceiling R so as to protrude. Thereby, the discomfort in appearance in the open state where the room is not partitioned can be reduced.

  As shown in FIG. 5, the guide rail 2 is perpendicular to the longitudinal direction of the top plate portion 21 and a flat plate-like top plate portion 21 that is disposed on the ceiling R side with the thickness direction directed in the vertical direction. A pair of mutually parallel flat plate-like side plate portions 22 extending perpendicularly downward from each of both end edges in the width direction, and inward from each of the lower end edges of the pair of side plate portions 22. It has a pair of plate-like rib portions 23 that extend at a right angle and that are opposed to each other at an interval through which a support shaft 36 that constitutes a part of a suspension wheel 3 to be described later is inserted.

A pair of slide guide portions 25 is formed. The pair of slide guide portions 25 project from the inner surfaces of the pair of side plate portions 22 at right angles toward the inside, and extend in parallel with the top plate portion 21 with a space therebetween. The tip is formed so as to face each other. That is, the moving space 20 includes the inner surface of the top plate portion 21, the inner surface of the pair of side plate portions 22, and the top plate portion 21 side of the pair of slide guide portions 25, as shown by the broken line region in FIG. 5. It is a space surrounded by a virtual plane including the surface. The vertical dimension of the moving space 20 in FIG. 5 is slightly smaller than the thickness dimension of the slide plate 26, for example, about 0.1 mm. Of course, the distance between the pair of side plate portions 22 in the moving space 20 in the moving direction of the slide plate 26 is slightly smaller than the dimension in the width direction perpendicular to the moving direction of the slide plate 26, for example, about 0.1 mm. ing. That is, the cross-sectional size in the width direction orthogonal to the longitudinal direction of the moving space 20 is slightly larger than the cross-sectional size in the width direction of the slide plate 26. Moreover, the thickness dimension of the slide guide part 25 is 1.8 mm, for example. Further, the distance between the tips of the pair of slide guide portions 25 is larger than the distance through which the support shaft 36 facing the tips of the pair of rib portions 23 is inserted. Thereby, when the guide rail 2 is looked up in the open state where the room is not partitioned, the pair of slide guide portions 25 are made invisible.

  As shown in FIG. 6, the guide rail 2 of the present embodiment abuts so that the free end of the first rail 16, and thus the end surface of the free end of the main body rail 11 and the end surface of the right end of the end rail 12 face each other.

The left end in FIG. 6, which is the other end of the slide plate 26, is disposed at the end.

  As shown in FIG. 8, the slide plate 26 of the present embodiment is a flat horizontally long rectangular plate having a long left and right direction in FIG. 8 along the moving direction of the slide plate 26 in a state of being arranged in the moving space 20 of the guide rail 2. It is formed in a shape. A long hole 27 is formed in the slide plate 26 along the moving direction. The long hole 27 is formed at the center in the width direction shown in the vertical direction in FIG. Further, the long hole 27 is arranged such that the right end thereof is close to the right end side in FIG. As shown in FIGS. 6 and 7, a first fixing screw 28 formed on the top plate portion 21 of the main body rail 11 has a first fixing screw 28 made of a small screw or the like inserted from below into the right end side of the long hole 27. The slide plate 26 is fixed to the first rail 16 by being screwed into the hole 29. Further, as shown in FIGS. 6 and 7, a second fixing screw 30 formed of a small screw or the like inserted from below into the left end side of the long hole 27 is formed on the top plate portion 21 of the end rail 12. The slide plate 26 is fixed to the end rail 12 by being screwed into the screw hole 31. Thereby, the 1st rail 16 and the end part rail 12, ie, the main body rail 11, and the end part rail 12, are connected. The guide rail 2 is formed with a plurality of mounting holes 33 used at the time of installing the guide rail 2 on the ceiling R at predetermined positions. A plurality of attachment holes 33 are provided in each of the main body rail 11, the end rails, and the storage rail 14.

  As shown in FIG. 8, the effective length dimension along the moving direction in which the first fixing screw 28 and the second fixing screw 30 of the long hole 27 formed in the slide plate 26 can be inserted is defined as La. The length dimension from the right end of the effective length to the right end of the slide plate 26 is Lb, the length dimension from the left end of the effective length of the long hole 27 to the left end of the slide plate 26 is Lc, and the moving direction of the slide plate 26 The overall length dimension along L is L (L = La + Lb + Lc), the length dimension from the left end of the first rail 16 shown in FIG. 6 to the center of the first screw hole 29 is Lx, and the right end of the end rail 12 is Effective when the distance from the center of the first screw hole 29 to the center of the second screw hole 31 is LG (LG = Lx + Ly). Length dimension La is equal to or longer than center distance LG (La ≧ LG) are formed. In the present embodiment, the length dimension Lx is the same as the length dimension Ly (Lx = Ly), and the effective length dimension La is longer than the center-to-center distance LG (La> LG).

That is, the effective length dimension La along the moving direction of the slide plate 26 through which the first fixing screw 28 and the second fixing screw 30 of the long hole 27 can be inserted is the first length formed on the top plate portion 21 of the main body rail 11.

The length dimension Lb is 13 mm, the length dimension Lc is 27 mm (L = 70 mm), the length dimension Lx is 15 mm, the length dimension Ly is 15 mm, and the center-to-center distance is 30 mm.

  The length dimension of the first fixing screw 28 is shorter than the value obtained by adding the thickness dimension of the slide plate 26 to the thickness dimension of the top plate portion 21 in which the first screw hole 29 is formed. This is preferable in the sense that the tip of the fixing screw 28 can be prevented from protruding outward from the top plate portion 21.

  As the length dimension of the second fixing screw 30, the thickness dimension of the slide plate 26 is added to the thickness dimension of the top plate portion 21 in which the second screw hole 31 is formed, like the first fixing screw 28. It is preferable to make it shorter than the value in the sense that the tip of the second fixing screw 30 can be prevented from protruding outward from the top plate portion 21.

  The inside of the main body rail 11 and the end rail 12 is slidable with a long hole 27 formed along the moving direction, and the moving space 20 of the slidable plate 26 is moved to the inner surface side of the top plate 21. Are formed on each of the body rail 11 and the end rail 12 so as to project at right angles from the inner surfaces of the pair of side plate portions 22 toward the inside, and are spaced apart from the top plate portion 21.
