Japanese Examined Patent Publication No. 2-28659 Japanese Utility Model Publication No. 4-59287

By the way, in the suspension runner device according to Patent Document 2, the bearing is fitted and fixed to the suspension bolt by press fitting, and the suspension bolt cannot be moved relative to the bearing in the vertical axis direction. .
For this reason, in this suspension runner device, when the partition is suspended from the suspension bolt, the suspension bolt cannot be moved upward by moving the suspension bolt upward in the vertical axis direction, and the suspension bolt interferes with the partition. However, there was a problem that it would be a difficult task requiring skill.

  In view of the problems of the above-described conventional suspension runner device, the present invention can avoid interference with the suspension member when the partition is suspended, and thus the partition can be easily suspended. An object is to provide a suspended runner device for a movable partition.

In order to achieve the above object, the movable partition suspension runner device of the present invention uses a suspension member having a vertical axis to suspend and support the partition disposed below the support mechanism and to contact the guide surface of the support mechanism. In the movable partition suspension runner device that allows the partition to move along the support mechanism by attaching the rotating traveling member to the suspension member so as to be rotatable about the vertical axis, the support mechanism is disposed above the suspension member. The top plate is located, and the suspension member can be moved relative to the bearing corresponding to the rotating traveling member in the vertical axis direction. When the partition member is suspended in the suspension member, the suspension member is moved in the vertical axis direction. When the relative movement is made upward, a relief portion for avoiding the suspension member from interfering with the top plate portion of the support mechanism is formed on the top plate portion .

  In this case, the rotating traveling members are arranged vertically with a predetermined interval along the vertical axis direction of the suspension member, and the bearings are maintained in a state where the distance between the upper and lower bearings corresponding to these rotating traveling members is kept constant. The connecting sleeve to be connected can be slidably attached to the suspension member.

  Further, a cover member that is pushed open by the raised suspension member can be provided in the escape portion formed in the top plate portion of the support mechanism.

  In addition, the suspension member may be a suspension bolt, and a pair of plane portions may be formed on the screw portion of the suspension bolt so as to be symmetrical with respect to the vertical axis.

  According to the movable partition suspension runner device of the present invention, the suspension member can be moved relative to the rotating traveling member in the vertical axis direction, and the suspension member is suspended in the vertical axis direction when suspended from the partition suspension member. By moving the partition upward, it is possible to avoid interference with the suspension member when the partition is suspended, whereby the partition can be easily suspended.

The support mechanism includes a top plate portion located above the suspension member. When the suspension member is moved relative to the bearing in the vertical axis direction upward direction, the suspension member is connected to the top plate portion of the support mechanism. Even if the amount of relative upward movement of the suspension member with respect to the bearing increases in the vertical axis direction by forming a relief portion on the top plate portion to avoid interference, the top plate portion and the suspension member of the support mechanism Can be reliably avoided, and the partition can be suspended more easily.

  Further, the rotary traveling members are arranged vertically with a predetermined interval along the vertical axis direction of the suspension member, and the bearings are connected in a state where the distance between the upper and lower bearings corresponding to these rotational traveling members is kept constant. By attaching the connecting sleeve to the suspension member in a slidable manner, the rotating traveling member can be easily and accurately attached to the suspension member, and the suspension member can be moved relative to the bearing in the vertical axis direction. Can do.

  In addition, by providing a lid member that is pushed open by the raised suspension member at the relief portion formed on the top plate portion of the support mechanism, the labor of attaching the lid member can be saved, and the top plate portion and the suspension member of the support mechanism While avoiding interference, it is possible to prevent dust from entering the support mechanism through the relief portion formed in the top plate.

  In addition, the suspension member is made of a suspension bolt, and a pair of plane portions are formed on the threaded portion of the suspension bolt so as to be symmetrical with respect to the vertical axis. Fixing can be easily performed using a tightening tool such as a spanner or a set screw.

Thus, after raising the suspension bolt 2 to a height position that does not interfere with the partition 4, the partition 4 is positioned so that the nut member 16 incorporated in the partition 4 is positioned below the suspension bolt 2.
Then, as shown in FIG. 3B, the screw portion 2c of the suspension bolt 2 is screwed into the female screw of the nut member 16, and the suspension bolt 2 is screwed into the nut member 16, as shown in FIG. Thus, when the predetermined screwing amount is reached, the nut member 16 and the suspension bolt 2 are fixed by fastening the set screw 17 so that the relative rotation around the vertical axis Op is stopped, and the suspension member 17 is suspended from the nut member 16. 2 is securely held without loosening the screwed state.
In this way, the work of suspending the partition 4 to the suspension bolt 2 is completed.

<Description of effects>
According to the suspended runner device 1A of the present embodiment, the bearings 6 are coupled in a state where the distance between the upper and lower bearings 6 corresponding to the two rollers 5 disposed vertically within the ceiling rail 3A is kept constant. When the connecting sleeve 20 is slidably mounted on the shaft portion 2 a of the suspension bolt 2, the suspension bolt 2 can be moved relative to the bearings 6 in the direction of the vertical axis line Op, to the suspension bolt 2 of the partition 4. Since the suspension bolt 2 is moved upward in the vertical axis Op direction when the suspension is suspended, interference with the suspension bolt 2 can be avoided when the partition 4 is suspended, and the partition 4 can be easily suspended. Can be done.
If the suspension bolt 2 is damaged, it has been conventionally necessary to replace the suspension bolt and the bearing in one set. However, the suspension bolt 2 can be moved relative to the bearing 6 in the direction of the vertical axis Op. Therefore, only the suspension bolt 2 can be replaced, and the running cost can be reduced.
