(Example) Figure 1 shows a tower that can be placed at the bottom of a desk.
2' is the long side frame and short side frame forming the ceiling, 3,3
Pillars on both sides of the rear surface that are inclined so that the upper end is closer to the front pillar 1 than the lower end when the Hayagura is viewed from the side;
Numerals 4 and 4 are stays that connect pillars 1 on both sides of the front and pillars 3 on both sides of the rear at a position slightly higher than the height of the lower horizontal beam of the desk, and 5 and 5 hang the elastic horizontal curtains described below. This is a hook for 6, 6 is the front pillar 1,
1 and between the lower ends of the columns 3, 3 on the rear surface, but this may be omitted.

Fig. 2 shows a cover made of one of blankets, quilted cloth, or other soft and rigid resin membranes for covering the tower. 10 is a rear part that covers the rear surface of the tower; and 11 is a concave double skirt part that extends from slightly above the horizontal bar at the bottom of the desk to the floor. The kneerest piece 12, which is wider than the front part of the tower, is attached to the ceiling part 8.
The upper part is continuous with the upper part, and the flare part 1 is continuous with both sides 9.
It consists of 3. Furthermore, in the embodiment shown in FIG. 2, the elastic horizontal curtain 14 stretched at the lower front of the tower is connected to the front ends of both skirt curtains 11, and a hanging cord or hanging hole 15 is provided at the upper end of the connecting part. . The hanging holes 15 are hooked onto hooks 5, 5 provided at predetermined locations on the pillars 1 on both sides of the front side of the tower.
