Description of the Related Art A screen capable of utilizing the front and back sides has already been disclosed in the application of Japanese Patent Application No. 7-119352 filed by the present applicant. The application further discloses means for holding the screen surface in an inclined state under tension. That is, a bracket is attached to the suspension pipe (1) installed on the ceiling so as to rotate in the horizontal direction at any time and to rotate in the vertical direction when a load larger than a predetermined load is applied, and the bracket is screened. It is fixed to the center of the winding tube (3), and is inward from the center of each of the ends of the winding tube (3) and the ends of the tension weight material (12) at the bottom of the screen. The supporting frame (6) which is bent in the direction of the arrow is pivotally attached (Fig. 6).

される。On the rotary fitting 3, an inclined support fitting 5 fixed to the center of the screen case 4 is installed. With this structure, the screen case 4 can rotate in the horizontal direction around the hanging pipe 1 as a unit with the inclined support fitting 5 and the rotating fitting 3. The inclined support fitting 5 is installed via the support shaft 6 so as to be vertically rotatable with respect to the rotary fitting 3. At that time, a high friction material such as leather or plastic is sandwiched in the contact surface between the lower end portion of the rotating metal fitting 3 and the inclined support metal fitting 5, and the screen case 4 and the screen which are hung on the inclined support metal fitting 5 at the time of flattening.
The tilt support fitting 5 does not rotate under a load such as the load 7 and is set to rotate only when a more load is applied.

る。On the mounting portion of the inclined support fitting 5 to the screen case 4 or on the rear surface of the screen case 4,
An insertion tube 9 for inserting the upper end of the tension rod 8 is installed. The tension rod 8 has a length corresponding to the vertical dimension when the screen 7 is pulled out to the maximum. At the lower end of the tension rod 8, hook means for hooking to a hooking portion 11 provided at the center of the tension weight pipe 10 at the lower end of the screen 7 is provided. As the tension rod 8, a hook rod 12 generally used for drawing out a screen can be used, and in this case, the hook rod 12 becomes the tension rod 8.

That is, when the white reflective surface 7a is not used, the structure below the rotating metal fitting 3 is rotated 180 degrees about the hanging pipe 1 so that the back surface 7b faces the front side. Maps, characters, symbols, pictures, etc. are displayed on the back surface 7b as described above, but they are selected in advance according to the intended use. That is, a map of Japan or the world for general classrooms of schools, music symbols for music rooms, Japanese syllabary charts for kindergartens, traffic signs for driving schools.

After the screen 7 is fully pulled out using the tension rod 8 (hook rod), one end of the tension rod 8 is fitted into the insertion tube 9 and the hook means is hooked on the hook portion 11. Then, the screen 7 is tilted at a desired angle via the tilt holding metal fitting 5. Thus, when viewing either the front side or the back side, the inclined state is maintained by being supported by the tension rod 8 so that it is easy to see. When not using both the front and back sides, the tension rod 8 may be removed and the entire screen 7 may be wound into the screen case 4. Although the tension rod 8 can be seen in the center when the back surface 7b is viewed, since the tension rod 8 is only one and is thin, it does not interfere with normal viewing.

It may be arranged so as to be rotatable at the lower end of the. In this case, the tension rod 8 is always located on the rear side of the screen 7 (to the viewer, the back side of the screen), and the tension rod 8 is completely in the way when the back surface 7b of the screen 7 is seen.

状態が確実に維持される。In a screen support stand such as a tripod stand, usually, a screen case is removably installed in the lower half of the stand, and the screen is pulled out from there to hook at the upper end of the stand. The hooking portion 11 of the tensioning pipe is locked to the locking means such as the above to tension the screen. In the present invention, however, the screen is inserted into the screen case supporting portion of the stand. The insertion cylinder 9 or the hook member is installed, and the tension rod 8 is arranged between the insertion cylinder 9 and the hook portion 11. This ensures that the screen tension is maintained.
