たれの揺動機構。[Claims for Utility Model Registration] 1. A seat block 2 formed by extending the front end side toward the front side of the seat plate is attached to the upper end of the leg support 1 of the rotating chair, and the seat block 2 is surrounded by the seat block 2. An arm member 3, which is a formed arm-shaped member and whose rear side is pivotally connected to the block 2 by a horizontal axis A, is provided toward the front of the support column 1,
An elongated hole C formed at the tip of the seat plate 4 to which the seat plate is attached is pivotally connected to the tip of the arm member 3 by a horizontal axis B, and the lower surface of the plate 4 and the upper surface of the block 2 are connected to each other. An elastic body such as a leaf spring 5 is interposed in between, and the lower end side of the backrest support member 6 to which the backrest is attached is extended toward the lower surface side of the seat plate 4, and the extension starting end 61 of the support member 6 is connected to the seat. It is pivotally connected to the rear end of the plate 4 by a horizontal axis D, and the extended tip 62 of the support member 6 is connected to the block 2 by an axis A which pivotally connects the arm member 3 to the seat block 2. A spring 7, such as a gas spring, is installed between the axis E provided at the extended tip of the support member 6 and the axis B at the front end of the arm member 3, and the stroke movement can be adjusted. The chair's unique feature is the rocking mechanism of the seat and backrest. 2. Attach a catch arm member 23 whose front end side extends toward the front side of the seat plate to the upper end of the leg support 1 of the rotating chair, and attach the seat arm member 23 to the tip of the seat arm member 23 to which the seat plate is attached. A long hole C formed at the tip of the plate 4 is pivoted by a horizontal shaft B,
In addition, an elastic body such as a leaf spring 5 is interposed between the lower surface of this plate 4 and the upper surface of the block 2, while the lower end side of the backrest support member 6 to which the backrest is attached is extended toward the lower surface side of the seat plate 4. The rear end of the seat plate 4 is pivotally connected to the extension start end 61 of the support member 6 through a horizontal axis D, and the extension tip 62 of the support member 6 is pivotally connected to the catch arm member 23. It is attached to the arm member 23 by an axis A provided on the support member 6, and the stroke movement can be adjusted between an axis E provided at the extended tip 62 of the support member 6 and an axis B at the front end of the seat arm member 23. A rocking mechanism for a seat plate and a backrest of a chair, characterized in that a spring 7 such as a gas spring as described above is installed.
