A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view and a side view of furniture, and FIG. 2 is a diagram illustrating a configuration of an expansion / contraction mechanism that is a part of the furniture.

  The furniture 1 of the present invention is formed in a column shape extending between the ceiling A and the floor B. In particular, the furniture 1 in the present embodiment is formed of a plate-like member having a predetermined length as shown in the left front view and the right side view of FIG. However, the furniture body in the present invention is not necessarily limited to being formed in a plate shape. For example, the furniture body may have a columnar shape or a prismatic shape.

  And the furniture 1 of the plate-shaped member which has predetermined | prescribed length is divided | segmented into three site | parts by the predetermined location of the longitudinal direction (height direction). Specifically, the furniture 1 is disposed between the upper end portion 10 that is located at the upper portion and that is in contact with the ceiling A, the lower end portion 30 that is located at the lower portion and is in contact with the floor B, and the upper end portion 10 and the lower end portion 30. It is divided into the intermediate part 20 and is comprised. In the present embodiment, as shown in FIG. 1, the length along the height direction of the upper end portion 10 is formed to be the longest, and the intermediate portion 20 and the lower end portion 30 are formed shorter than the upper end portion 10. Yes. Thereby, the intermediate | middle site | part 20 is located in the floor B vicinity. However, the length of each part 10,20,30 is not limited to the length as shown in FIG. For example, the lower end part 30 may be formed to be the longest.

  Note that the furniture 1 is not necessarily divided into three parts, and may be divided into more parts. In that case, the parts located above the intermediate part 20 are collectively referred to as the upper part, and the parts located below the intermediate part 20 are collectively referred to as the lower part.

  The intermediate portion 20 is connected to the upper end portion 10 and the lower end portion 30 via an expansion / contraction mechanism. Here, the configuration of the telescopic mechanism will be described with reference to FIG.

  First, as an expansion / contraction mechanism, the intermediate portion 20 includes bolts 21 and 22 built in at the upper end side and the lower end side, respectively, in the center in the width direction. Specifically, a lower end side bolt 22 (lower end portion connecting member) in which a positive screw (right thread) is formed is provided on the lower end side in the longitudinal direction of the intermediate portion 20, and a reverse screw ( The upper end side bolt 21 (upper end part connection member) in which the left screw) was formed is provided. Correspondingly, the lower end side of the intermediate portion 20 is provided with a lower end side nut 24 in which a positive screw into which the lower end side bolt 22 is inserted and screwed is cut on the inner surface. , An upper end side nut 23 in which a reverse screw into which the upper end side bolt 21 is inserted and screwed is cut on the inner surface is provided. In addition, between the lower end side nut 24 and the upper end side nut 23, a cylindrical member 25 that is not threaded is provided, and a part of the lower end side bolt 22 and the upper end side bolt 21 can be inserted. It is configured as follows.

  As shown in FIG. 2, one end side of the lower end side bolt 22 is located inside the intermediate portion 20, and the other end side protrudes from the lower end side of the intermediate portion 20.
