Claims

[Scope of Claim for Utility Model Registration] 1. Ceiling rail, traveling body, suspension rod, movable wall, upper and lower contact members, upper and lower lifting shafts, and 4-point link type shaft drive mechanism. A movable partition device comprising: an upper and a lower elevating shaft whose elevating strokes are different from each other, wherein the movable wall is connected to the ceiling via the suspension rod and the running body. It is movably suspended and supported on the rail, and the upper and lower contact members are disposed on the upper and lower edges of the movable wall so as to be able to protrude and sink toward the ceiling and floor. , the two lifting shafts are disposed so as to be able to rise and fall within the movable wall while holding the upper and lower contact members at their tips, respectively, and the shaft drive mechanism has two types of threaded portions that are oppositely threaded to each other. An operating shaft, a pair of nuts screwed onto each threaded portion of the operating shaft, and a link member are pivotally connected in a diamond shape, and the left and right pivot points are pivotally connected to each of the nuts. It is also equipped with a four-point link that pivots the upper and lower lifting shafts at the upper and lower pivot points, respectively, and the left, which is located in the upper half,
The length of the right link member and the left located in the lower half,
A movable partition device characterized in that the lengths of the right link members are different from each other. 2. The movable partition device according to claim 1, wherein the lengths of the left and right link members located in the lower half are set smaller than the lengths of the left and right link members located in the upper half. . 3. Equipped with a ceiling rail, a traveling body, a suspension rod, a movable wall, upper and lower contact members, upper and lower lifting shafts, a four-point link type shaft drive mechanism, and a stroke changing mechanism. a movable partition device, wherein the movable wall is movably suspended and supported on the ceiling rail via the suspension rod and the running body, and the upper and lower contact members are connected to the movable wall. The lifting shafts are disposed at the upper edge and the lower edge so as to be able to protrude and sink toward the ceiling surface and the floor surface, and both the lifting shafts hold the upper and lower contact members at their tips, respectively, and move the moving wall. The shaft drive mechanism includes an operating shaft having two types of threaded portions with opposite threads, and a pair screwed onto each threaded portion of the operating shaft. A nut and a link member are pivoted in a diamond shape, and the left and right pivot points are pivoted to each of the nuts, and one of the vertical pivot points is directly connected to one of the upper and lower lifting shafts, and the other is connected directly to one of the upper and lower lifting shafts. The four-point link is connected to the other of the upper and lower lifting shafts via a stroke changing mechanism, and the stroke changing mechanism includes a rotating member having two points of action at different distances from the fulcrum. It is characterized by connecting either the upper or lower pivot point of the 4-point link to one point of application, and connecting either the upper or lower lifting shaft to the other point of action. A mobile partition device.
