Abstract

PROBLEM TO BE SOLVED: To effect a smooth movement in a storage part and a smooth movement in a direction converting place without causing a twist. SOLUTION: A hanger block 23, to which a lifting bolt 17 of a runner is attached, is secured to an upper bracket 25, while a lower bracket 28 is secured to the top end of a movable panel 3. The upper and lower brackets 25, 28 are connected by a link 30. If the posture of the panel 3 gets out of its normal posture and the interval between both runners increases, the link 30 takes a vertical posture under the weight of the panel 3, with the result that both the runners 4 return to their normal positions.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device for a suspended movable panel.

[0002]

2. Description of the Related Art Generally, a moving panel of a partitioning device is suspended on a ceiling rail by a pair (two) of runners.
In a partition part of a room or a transfer path, the movable panel is in a posture overlapping with a ceiling rail in plan view. On the other hand, two storage rails extending in parallel in plan view are arranged in the storage portion of the movable panel, and a runner is hung on the two storage rails, and the movable panel is perpendicular to the storage rail in plan view. Thus, a large number of movable panels are stored in a state of being stacked in parallel.

[0003] In this case, when the movable panel is in a posture intersecting the ceiling rail in plan view at the place of the storage section or the direction changing place where the ceiling rail is L-shaped or cross-shaped in plan view, two runners are formed. A twist may occur between the ceiling rail. Therefore, in order to make the moving panel easy to move by eliminating the twisting when the moving panel is put in and out of the storage unit and to change the direction, it has been considered that the distance between the pair of runners can be made wider and narrower. No. 98579, Japanese Patent Publication No. 59-48275, Japanese Patent Publication No. 6-68229, Japanese Utility Model Publication No. 7-6431, etc.).

[0004]

Among these prior arts, Japanese Patent Publication No. 6-68229 and Japanese Utility Model Publication No. 7-6431 disclose a pair of runners movable along the frontage of a movable panel. Therefore, it is not possible to prevent the occurrence of a twist between the runner and the ceiling rail, and when the twist occurs, there is a problem that the operator has to grasp the movable panel by hand and shake it.

On the other hand, in Japanese Patent Application Laid-Open No. 58-98579, the runners are urged by springs so as to narrow the gaps to regular intervals when the gaps between the runners are widened. Even if it spreads, the runner returns to its original position with a spring and is self-help, so it is thought that the twist can be automatically eliminated. However, when the spring is provided, the structure becomes more complicated, and furthermore, there is a problem that the twisting when the interval between the storage rails is smaller than a specified dimension due to a construction error or the like cannot be eliminated.

Further, Japanese Patent Publication No. 59-48275 discloses that a transmission mechanism for manually moving a runner is provided inside a moving panel, but this only makes the structure extremely complicated. Alternatively, there is a problem that the operation of returning the posture of the movable panel is troublesome since each manual operation is required. The present invention aims to improve these situations.

[0007]

In order to achieve this object, the present invention provides a suspended movable panel in which a movable panel is suspended by a plurality of runners running on a ceiling rail. One is configured to be attached to the movable panel via a link that can rotate around a rotation axis extending in the thickness direction of the movable panel.

[0008]

[Operation / Effect] With such a configuration, the rotation of the link can change the distance between the plurality of runners. For example, when the movable panel is moved in the storage section, the movable panel assumes a posture different from the normal posture, so that the distance between the runners is widened, or the spacing between the storage rails is varied due to a processing error or a construction error. When the distance between them changes, the link tilts to a posture inclined with respect to the vertical line.

In this case, when the link is tilted, the movable panel also rises slightly, so that the weight of the movable panel acts to return the link to the original position extending along the vertical line. . In other words, the weight of the moving panel always acts to keep both runners at regular intervals. Therefore, when the movable panel is moved in the storage section or passed through the L-shaped or cross-shaped conveyance path, the gap between the runners is changed more or less than the regular interval due to the displacement of the movable panel from the regular posture. However, the runner is returned to the normal position by the weight of the movable panel, and therefore, the movable panel can also return to the normal posture and run smoothly.

As described above, according to the present invention, with a simple structure in which the moving panel is simply suspended and supported via the link, the running between the runner and the rail can be removed and the vehicle can run smoothly. Further, even if there is a variation in the interval between the two storage rails due to a construction error of the storage unit, a processing error of the storage rail, or the like, the variation can be absorbed by the rotation of the link. The movement of the moving panel can be performed smoothly.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing the vicinity of the storage section, and FIG. 2 is a front view of FIG. 1. Two storage rails 1 are arranged in parallel in the storage section. One storage rail 1 is connected to both storage rails 1. The movable panel 3 includes a pair of runners 4, and when the two runners 4 move between the storage rail 1 and the transport rail 2, the movable panel 3 is moved in and out of the storage unit.

The transport rail 2 is connected to a main rail (not shown) disposed at a partition of the chamber. In addition,
A plurality of transport rails 2 may be connected to one storage unit. All of these rails are included in the claimed ceiling rails. Next, details of each part will be described with reference to the drawings in FIG. FIG. 3 is a sectional view taken along the line III-III of FIG.
(A) is a plan sectional view taken along the line AA in FIG. 3, and (B) is a BB in FIG.
5A is a sectional view taken along the line VV in FIG.
(B) is a sectional view taken along the line BB of (A), and FIG. 6 is a view showing the operation.

As shown in FIG. 3, each of the rails 1 and 2 is formed in a substantially C-shape with a downward opening in cross section.
It is fixed by welding or the like to a bracket 5 hanging down from a beam material, a ceiling base, or the like (it goes without saying that it may be directly attached to a ceiling surface or the like). An edge member 6 is fixed to the lower surfaces of the rails 1 and 2, and the edge member 6 supports a ceiling plate 7.

As shown in FIG. 2 and FIG.
Has a horizontal frame member 8 arranged above and below it and a vertical frame member 9 arranged on the left and right sides. A fire-resistant panel 11 is provided on both front and back surfaces of a rectangular frame composed of these frame members 8,9. It is stuck. As shown in FIG. 3, the upper horizontal frame 8 is located below the upper end surface of the movable panel 3, and the runner 4 is attached to a reinforcing member 12 fixed to the upper horizontal frame 8.

Each of the frame members 8, 9 and the reinforcing member 12 is made of a square steel pipe (or may be made of a channel material). The reinforcing member 12 is also positioned below the upper end surface of the panel 11, and therefore, a groove 13 is opened in the upper end surface of the movable panel 3 over its entire length. A top edge 14 is attached to the groove 13 (the top edge 14 is omitted in FIGS. 5 and 6). Although not shown, edges are also attached to the left and right end surfaces of the movable panel 3.

The runner 4 has a main body block 15 having a rectangular shape in plan view.
And two pairs of running wheels 16 are mounted on each surface around the main body block 15. Also, body block 15
A suspension bolt (suspension shaft) 17 extending downward is attached to. The suspension bolt 17 is rotatably attached to the main body block 15 via a thrust bearing (not shown).

Further, a support sleeve 19 is fixed to the upper surface of the main body block 15 via an auxiliary block 18. Guide rollers capable of rolling on the four corners of the support sleeve 19 so as to freely contact the inner surfaces of the rails 1 and 2 are provided. 20 is installed so that it can rotate horizontally. A ball 22 is rotatably mounted on the lower surface of the support sleeve 19 via a cover (retainer) 21.

Although not shown, a guide block is disposed at the intersection of the transfer rail 2 and the storage rail 1, and the guide block is provided between the transfer rail 2 and the storage rail 1. A guide groove in which the guide roller 20 fits and a guide plate against which the ball 22 contacts are provided when the runner 4 is shifted between the guide rollers. As shown in FIG. 5, the lower end of the suspension bolt 17 is screwed into a hanger block 23 and is locked to the hanger block 23 by a nut 24. The hanger block 23 is fixed to the upper bracket 25 having a U-shape with a downward side section by screws 26.
Is fitted in a hole 27 formed in the reinforcing member 12.

The hanger block 23 and the upper bracket
25 may be an integral structure. On the other hand, a portion of the bottom surface of the reinforcing member 12 below the runner 4 is provided with the upper bracket.
An upward-opening U-shaped lower bracket 28 corresponding to 25 is screwed
A pair of left and right links 30 are rotatably attached to the upper and lower brackets 25 and 28 by pins 31.

The pins 31 extend in the thickness direction of the movable panel 3, so that the distance between the left and right runners 4 can be changed by the rotation of the link 30. The number of the links 30 at one runner 4 may be only one or three or more. In addition, it is not always necessary to use the pins 30 to attach the link 30. For example, a spherical head may be integrally provided at the end of the link 30 and may be supported by the upper and lower brackets 25 and 28.

The hanger block 23 and the link 30 are housed in the groove 13 of the movable panel 3, and thus, there is an advantage that the appearance can be improved. In the above configuration, since the distance between the left and right runners 4 can vary widely, even if the distance between the two storage rails 1 varies due to a construction error or the like, the variation can be absorbed and the vehicle can run smoothly.

When the movable panel 3 is taken in and out of the storage section, the movable panel 3 and the two storage rails 1 may not be perpendicular to each other in a plan view, as shown by a dashed line in FIG. Then, the distance between both runners 4
L1 is wider than the interval L0 in the normal posture, and both links 30 are inclined with respect to the vertical line A as shown in an exaggerated manner in FIG.

In this state, the movable panel 3 rises slightly more than in the normal posture, and the weight of the movable panel 3 acts to return the link 30 to the vertical posture. As a result, the movable panel 3 returns to a position orthogonal to the storage rail 1 in a plan view, and can be smoothly moved. Even in the case where the direction is changed at a place where the rail is L-shaped or cross-shaped in plan view, the traveling can be smoothly performed by the same operation.

The structure in which the link 30 is fitted into the groove of the upper and lower brackets 28 as in the embodiment has an advantage that it is possible to suppress the lateral movement (the movement in the thickness direction) when the movable panel 3 is moved. In this embodiment, both left and right suspension bolts 23 are connected to the moving panel 3 by the link 30. One suspension bolt 23 is fixed to the movable panel 4 and one suspension bolt 23 is fixed.
Only the link 30 may be attached.

The position and form of the link 30 are not limited to those shown in the figure, and the link 30 may be directly attached to the runner 30 as shown in FIG. In this case, link 30
May be fixed to the runner 4 so as not to rotate.
