Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel suspension structure in which a screw rod is screwed to a screwed object to suspend and support the panel on a support member.

[0002]

2. Description of the Related Art Generally, in a suspension structure for a panel of this type, a threaded rod is suspended and supported by a pair of drive runners, which are self-propelled along a ceiling rail. Further, a pair of connecting shafts is supported on both side portions in the width direction of the partition panel so as to project upward, and a screw hole is formed in the upper end surface of the connecting shaft. Then, the partition rods are suspended and supported by the pair of drive runners on both sides in the width direction by screwing the screw rods of the drive runners into the screw holes of the connecting shafts.
It should be noted that a nut is screwed onto the threaded rod, and by tightening this nut, the threaded rod and the connecting shaft are firmly connected and relative rotation between them is prevented. Then, the partition panel is moved between the storage position and the partition position as the drive runner self-propels. Further, the vertical position of the partition panel with respect to the drive runner can be adjusted to an optimum position by changing the screwing amount of the screw rod with respect to the screw hole of the connecting shaft.

Usually, the ceiling rail has a corner portion, and the drive runner automatically runs along the ceiling rail while automatically turning the corner portion. However, when the power supply to the drive runner is cut off due to a power outage or the like, the drive runner is not operated, and thus the user needs to manually move the partition panel. In this case, even when the drive runner is turned in the corner portion, the turning needs to be performed manually. Therefore, a gearbox is arranged in the partition panel, and the lower end of the connecting shaft is connected to a predetermined gear in the gearbox. Then, when the handle is inserted into the gear box from the outside of the partition panel and the handle is rotated, the connecting shaft is rotated via the gear in the gear box, and the drive runner is rotated with the rotation. ing.

[0004]

However, in the above-mentioned prior art, only by screwing the screw rod into the screw hole of the connecting shaft and tightening it with the nut, the vibration and the impact from the outside caused by the movement of the partition panel can be obtained. When the nut is loosened due to, for example, the relative rotation between the threaded rod and the connecting shaft is easily allowed. Therefore, in such a case, when the drive runner automatically turns at the corner portion of the ceiling rail, or when the drive runner turns manually via the connecting shaft, the drive runner is connected to the screw rod. Relative rotation occurs with the shaft, and the screwing amount of the screw rod into the screw hole of the connecting shaft is changed. Then, the vertical position of the partition panel with respect to the drive runner is changed,
There is a problem that the panel may be tilted in the width direction and, in the worst case, the partition panel may fall off the drive runner.

The present invention has been made to solve the above problems, and an object of the present invention is to support a panel by suspending it on a supporting member by screwing a screw rod to a screwed body. Also provides a panel suspension structure capable of reliably preventing relative rotation between the screw rod and the screwed object and reliably suspending and supporting the panel in a stable state with respect to the support member. To do.

[0006]

In order to achieve the above object, in the invention described in claim 1, a screw rod is provided on either one of the support member or the panel, and the other is screwed to the screw rod. In a panel suspension structure in which a threaded body is provided and a threaded rod is screwed to the threaded body to suspend and support the panel on a support member, between the threaded rod and the threaded body , A rotation preventing member that engages with the screw rod and the threaded body so as not to rotate relative to each other is provided so as to be attachable to and detachable from both members.

Further, in the invention according to claim 2, the threaded body is a connecting shaft having a screw hole in an upper end surface thereof, and the connecting shaft is supported by the panel, and the screw rod is supported by the supporting member. At least one flat surface portion is formed on the outer periphery of the connecting shaft and the threaded rod, respectively, and the detent member engages with the flat surface portion of the threaded member while the threaded rod is inserted into the flat portion. In addition to forming an insertion hole that prevents relative rotation, an engaging piece that engages with the flat surface of the connecting shaft when mounted on the upper end of the connecting shaft and prevents relative rotation with the connecting shaft is provided. is there.

[0008]

Therefore, according to the present invention, the anti-rotation member engages with the threaded rod in a non-rotatable manner and also engages with the threaded body in a non-rotatable manner. Therefore, the threaded rod and the threaded body are connected to each other via the detent member such that they cannot rotate relative to each other.
