TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for suspending a movable partition panel for partitioning a large room such as a banquet hall from a ceiling.
[0002]
[Prior art]
As a conventional suspension support device of this type, for example, there is one described in Japanese Patent Application Laid-Open No. 1-180440 filed by the present applicant.
[0003]
In this partition panel, a traveling roller device that travels along a rail provided on the ceiling suspends a suspension rod having a male thread at a lower portion, and has a female screw threadedly engaged with the male thread of the suspension rod, and at the lower end. The tubular body provided with the enlarged diameter flange is vertically penetrated through the upper frame material of the partition panel so that the upper flange material is supported by the enlarged diameter flange. A ring-shaped stopper is loosely fitted.
[0004]
A pair of planing surfaces that are parallel to each other are formed on the outer peripheral surface of the upper end of the cylindrical body, and a pair of contact surfaces that can engage with the planing surface are formed on the inner peripheral surface of the lower end of the stopper. ing.
[0005]
When the cylinder is rotated, the cylinder moves vertically with respect to the suspension rod, and the partition panel supported by the enlarged flange of the cylinder also moves vertically.
[0006]
After the height adjustment work of the partition panel performed in this manner, the abutment surface of the stopper is engaged with the planing surface of the suspension rod, and the inner end of the set screw inserted into the stopper is tightened to the suspension rod. Then, the suspension support rod and the cylinder cannot rotate relative to each other.
Therefore, even if an unexpected external force is applied to the cylinder, the cylinder does not rotate relative to the suspension rod, and the height of the partition panel does not change.
[0007]
[Problems to be solved by the invention]
In the above suspension device, if the stopper is damaged or the screw thread of the screw hole for screwing the set screw is crushed, the cylinder must be completely removed from the suspension rod, that is, the partition. If the panel is not completely removed from the suspension rod, the fastener cannot be replaced.
[0008]
Also, at the time of assembling the device, before the cylinder is screwed into the suspension support rod and the partition panel is suspended, the stopper must be mounted on the suspension support rod in advance. After the partition panel is suspended by the support rod, the stopper cannot be attached to the suspension support rod, and there is a problem that the assembling work is complicated.
[0009]
