  In the configuration of the cited document 1, four wheels are rotatably supported by the runner body of the lower runner, the wheels are accommodated in the lower rail, and roll on the bottom of the lower rail. That is, since the wheel is completely contained in the lower rail, the height of the lower rail is required, and therefore there is a problem that a work for embedding the lower rail in the floor surface is required.

  The present invention has been made in view of such problems, and the object thereof is to deal with a case where the lower rail can be easily laid on the floor surface and the distance between the floor surface and the ceiling surface varies. It is providing the partition apparatus which can perform, and the runner for the partition.

In order to achieve the above-described object, the invention described in claim 1 is a panel movable by an upper runner that moves along an upper rail, a lower runner that moves along a lower rail, and an upper runner and a lower runner. In the partition device having

However, even if the wheel is separated from the lower rail, since the rail sliding member is engaged with the engaging portion of the lower rail, derailment can be prevented and the posture of the panel can be regulated.

  Since the weight of the panel can be normally received by the lower runner, the weight of the panel does not act on the upper rail, and the configuration of the upper rail can be simplified in terms of strength. For this reason, it is good for the upper runner to form a clearance in the vertical direction with the panel in a state where the wheels of the lower runner are in contact with the running surface.

  On the other hand, the upper runner is connected to the panel so as not to be relatively movable in the horizontal direction, so that the posture of the panel can be regulated by the upper runner. If the distance between the floor and the ceiling is long, the clearance between the floor and the ceiling can be accommodated by eliminating the vertical clearance and receiving the weight of the panel with the upper runner. it can.

  The wheel support member is rotatably connected to the panel, and the upper runner is connected to the panel so as not to rotate relative to the panel, so that the panel can rotate with respect to the lower runner and the upper runner.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a partition device of the present invention. In the figure, the partition device 10 is provided with a plurality of panel elements 20 between an upper rail 12 and a lower rail 14. A pair of panel elements 20 are connected to each other by a hinge at a side end where the pair of panel elements 20 are attached to each other, thereby forming one panel 22. In this example, the two panels 22 and 22 constitute a sliding door, and each panel 22 also serves as a folding door.

  As shown in FIG. 2, each panel element 20 and a panel 22 composed of a pair of panel elements 20 include an upper runner 16 that moves along the upper rail 12, and a lower runner 18 that moves along the lower rail 14. It is possible to move along the rail.

  As shown in FIG. 3, the lower runner 18 has one wheel 30, a columnar wheel support member 32 that supports the wheel 30, and a cylinder that can move up and down relatively with respect to the wheel support member 32. Rail-shaped sliding member 34.

  The axle support member 32 has a portion extending on both sides of the wheel 30, and the wheel 30 is supported by the axle 31 of the wheel 30 passing through the portion.

  The rail sliding member 34 also has a portion extending on both sides of the wheel 30, and elongated holes 34a, 34a extending in the vertical direction are formed in the portion. And the axle 31 of the wheel 30 which penetrates the said wheel support member 32 is slidably inserted in these long holes 34a. The wheel support member 32 is inserted through an upper hole 34c formed at the top of the rail sliding member 34, and the wheel support member 32 and the rail sliding member 34 are relatively movable in the vertical direction and relatively rotated. Linked impossible. Engagement portions 34b and 34b extending in the horizontal direction are formed at the lower end of the portion of the rail sliding member 34 that extends on both sides of the wheel 30.

  A mounting bracket 36 is rotatably attached to the top of the wheel support member 32 by a rivet 38. Since both ends of the mounting bracket 36 are bent downward from the top of the wheel support member 32 and further bent horizontally, and are attached to the lower portion 20a of the panel element 20 (see FIG. 4), as a result, the panel element 20 The wheel support member 32 and the rail sliding member 34 are rotatable about the vertical direction as a rotation axis.

  The lower rail 14 has on its upper surface a running surface 14a on which the wheels 30 of the lower runner 18 roll, and is provided in parallel on both sides of the running surface 14a so as to slide on the rails of the lower runner 18. It has the engaging part 14b which the engaging part 34b of 34 engages. The lower rail 14 is fixed on the floor surface F, and the thickness thereof can be, for example, 3 mm or less. Therefore, even if it is installed on the floor surface, it can cope with barrier-free.

  Next, as shown in FIG. 2, the upper runner 16 has a pair of wheels 40 and a runner body 42 that pivotally supports the wheels 40. The pair of wheels 40 are attached to the runner main body 42 while shifting their positions along the rails (see FIG. 5).

  The bolt 44 attached to the upper part of the panel element 20 passes through a through hole 42a formed in the runner main body 42, and the head portion 44a of the bolt 44 is connected to an enlarged diameter part 42b formed in the upper part of the through hole 42a. It is inset. Since the head portion 44a of the bolt 44 cannot enter below the enlarged diameter portion 42b of the through hole 42a, the downward displacement of the bolt 44 is limited. Under this downward displacement limitation, the upper runner 16 The panel element 20 is connected so as to be relatively movable in the vertical direction and not to be relatively movable in the horizontal direction. Since the bolt 44 is integrally fastened to the panel element 20 so that the vertical height thereof can be adjusted by the nut 46, the distance that can be relatively moved in the vertical direction between the upper runner 16 and the panel element 20 is set. It is adjustable. Further, since the bolt 44 can rotate within the through hole 42a, the upper runner 16 is connected to the panel element 20 so as to be relatively rotatable with the vertical direction as a rotation axis.

  The upper rail 12 has a box shape and is attached to the lower side of the ceiling surface C. The upper surface of the lower portion serves as a running surface 12a on which the wheels 40 run, and the lower center portion has a lower portion of the runner main body 42. A rail groove 12b through which the bolt 44 is inserted is formed.

  The upper runner 16 and the lower runner 18 are connected to the panel element 20 at the center in the width direction of each panel element 20.

  The upper rail 12 and the lower rail 14 are laid adjacent to each other in two rows corresponding to the two panels 22.

  In the partition device configured as described above, in a normal state, as shown in FIG. 2, the bolts are provided so that a vertical clearance is provided between the head portion 44 a and the enlarged diameter portion 42 b of the bolt 44. The height of 44 is adjusted. Therefore, the weight of the panel 22 does not act on the upper runner 16, and the weight of the panel 22 acts on the lower runner 18 via the mounting bracket 36. The wheel support member 32 and the wheel 30 that is pivotally supported by the wheel support member 32 are descended to the maximum, and the wheel 30 is pressed against the running surface 14 a of the lower rail 14.

  In order to make the partition device 10 act as a sliding door in this state, as shown in FIG. 5 (b), when the panel 22 is moved along the rail, the wheels 30 of the lower runner 18 are placed on the running surface 14 a of the lower rail 14. And the engaging portion 34b of the rail sliding member 34 slides while engaging with the engaging portion 14b of the lower rail 14. Further, the wheel 40 of the upper runner 16 also rolls on the running surface 12 a of the upper rail 12. Although the weight of the panel 22 does not act on the upper runner 16, the upper runner 16 regulates the posture of the panel 22 by regulating the horizontal position of the upper end portion of the bolt 44 attached to the panel element 20.

  Further, in order to make the partition device 10 act as a folding door, as shown in FIG. 5C, when the pair of panel elements 20 and 20 constituting the panel 22 are bent by a hinge, each panel element 20 is an upper part. It can rotate with respect to the runner 16 and the lower runner 18, and can rotate to the position orthogonal to a rail at the maximum. At this time, since the panel element 20 is supported by the upper runner 14 and the lower runner 16 and the posture thereof is regulated, the panel element 20 is prevented from falling. Thus, the space in which the partition device 10 is set can be greatly opened.

  In such a partition device 10, if the distance between the ceiling surface and the floor surface is constant along the rail, the positional relationship between the upper runner 16 and the lower runner 18 can be made to work constant. When the distance between the upper runner 16 and the floor surface is not constant along the rail, the positional relationship between the upper runner 16 and the lower runner 18 cannot be made constant. In particular, when the length of the rail is increased, the possibility that the distance varies is increased. For example, in the example of FIG. 6, the distance X between the leftmost upper rail 12 and the lower rail 14 is different from the distance Y between the rightmost upper rail 12 and the lower rail 14, and Y> X.

  In such a case, in the panel element 20 located on the right side, as shown in FIGS. 8 and 9, in the upper runner 16, the head portion 44 a of the bolt 44 moves to the lowermost portion of the expanded diameter portion 42 b and the lower portion. The wheel support member 32 and the wheel 30 of the runner 18 are displaced upward with respect to the rail sliding member 34. For this reason, the weight of the panel 22 acts on the upper runner 16 and can be dealt with by switching the runner receiving the weight. Thus, even if the weight is received by the upper runner 16, the engaging portion 34b of the rail sliding member 34 is always engaged with the engaging portion 14b of the lower rail 14, so that derailment can be prevented. When moving 22 along the rail, the engaging portion 34b can move while sliding the engaging portion 14b. Further, as the panel 22 moves and moves to the left, the distance between the upper rail 12 and the lower rail 14 becomes shorter, and accordingly, the wheel support member 32 and the wheel 30 move downward. When the wheel 30 comes into contact with the running surface 14a, the bolt 44 moves upward and a clearance is generated between the head 44a of the bolt 44 and the runner main body 42.

  Thus, even when the distance between the upper rail 12 and the lower rail 14 changes continuously, it is possible to cope with this by switching the runner receiving the weight of the panel between the upper runner 16 and the lower runner 18. As shown in FIG. 7, it can act as a sliding door or a folding door.

  As described above, in the present embodiment, the wheel 30 is appropriately lifted and separated from the lower rail 14 to cope with a change in the distance between the upper rail 12 and the lower rail 14. By making the wheel 30 separable from the lower rail 14, the thickness of the lower rail 14 can be reduced, and a barrier-free floor surface can be obtained by simple laying work. Even if the wheel 30 is separated from the lower rail 14, the engaging portion 34 b is engaged with the engaging portion 14 b of the lower rail 14, so that the position of the panel 22 is restricted in order to restrict the lower end position of the panel 22. can do. Therefore, even when the panel 22 is rotated, the fall or the like is prevented.

  Further, since the weight of the panel is normally received from the lower runner 18 by the lower rail 14, the structure of the upper rail 12 can be simplified in strength, and the laying work of the upper rail 12 is also easy. And it can be performed at low cost.
