According to the present invention, the above problem is solved as follows.
(1) In a cross panel in which a cross member is stretched on a frame that is looped in the vertical direction, the frame is connected to a substantially inverted U-shaped upper frame, and the upper end can be connected to the lower end thereof. It is composed of a U-shaped lower frame and a substantially horizontal intermediate frame that can be connected to the upper frame or the lower frame at both ends, and is provided on the outer peripheral edge of the cloth material at an intermediate portion in the vertical direction. A substantially inverted U-shaped upper bag-shaped portion divided vertically by two insertion openings and a substantially U-shaped lower bag-shaped portion are formed, and the upper frame is formed in the upper bag-shaped portion and the lower portion The lower frame is housed in the bag-like portion from the insertion opening, and the ends of the upper and lower frames and the intermediate frame are connected to each other.

(2) In the above item (1), the T-shaped connecting piece is fitted to the pipe-shaped upper frame, the lower frame, and the end of the intermediate frame, and the ends of the frames are connected to each other.

(3) In the above item (1) or (2), the intermediate frame is bent outward so that the cloth member can be expanded outward.

(4) In any of the above items (1) to (3), the upper part of the upper frame is bent forward in the cross panel disposed at the rear part of the table.

(5) In any one of the above items (1) to (4), the lower frame is composed of an L-shaped frame and a vertical frame connectable to the lower end thereof, and the lower end of the lower bag-shaped portion of the cloth material The lower bag-shaped portion is divided into two, an L-shaped bag-shaped portion and a vertical bag-shaped portion, and the L-shaped frame is placed in the L-shaped bag-shaped portion, The vertical frames are housed in vertical bag-shaped portions, and support legs are connected to the ends of the L-shaped frame and the vertical frame.

  According to the first aspect of the present invention, the frame is divided into an upper frame, a lower frame, and an intermediate frame, and an upper bag-like portion and a lower bag that are divided up and down by an insertion port at the outer peripheral edge of the cross Since the shape portion is formed, it is easy to assemble and carry even a frame having a large height, and it is easy to stretch the cloth material on the frame.

  According to the invention described in claim 2, by using the T-shaped connecting piece, the connecting operation of the upper frame, the lower frame and the intermediate frame can be easily performed only by fitting.

  According to the third aspect of the invention, by bending the intermediate frame outward, it is possible to give tension to the cloth material, and the three-dimensional bulge toward the rear improves the appearance.

  According to the fourth aspect of the invention, the cross material stretched on the upper frame suppresses the illumination from the ceiling that is projected onto the top plate of the table, making it easy to see a display such as a personal computer.

  In addition to the bulging effect of the third aspect, an excellent design effect can be obtained.

  According to the fifth aspect of the present invention, even when the support leg is attached to the lower end corner of the lower frame, the cloth material can be easily stretched on the lower frame, and the L-shaped frame divided by the support leg. Since the end portions of the vertical frames are connected to each other, the connecting operation between the frames and the supporting legs can be performed efficiently at the same time.
