When the L-shaped elastic structure 140 rotates around the center 5 and falls down as shown by the solid line in FIG. 27, the hook 148 of the leaf spring structure 144 is pulled by the poster 139 and FIG. It is bent as shown in a). Therefore, a restoring force for returning the hook-shaped portion 148 to the original extended state is applied to the poster 139 as tension. As shown in FIG. 22 and the like, the L-shaped holding member 130 has a structure in which two sides having equal lengths form an inner angle of 90 °, and the hook-like portion 148 of the leaf spring structure 144 is The tension is applied in a direction that bisects the interior angle of the corner of the poster 139 when the poster 139 is set in the frame 150 because the tension is extended and bent in a linear direction that bisects the interior angle of the corner of the frame 150. The direction of the tension is not limited to a direction that bisects the corner, but is preferably a direction that bisects the corner so as not to cause wrinkles or the like on the poster 139 as described above.

The laid-down state shown by a solid line in FIGS. 26 and 27 is a stable state for the following reason. That is,
As shown in FIG. 28, in this folded state, a force parallel to the bottom portion 154 of the frame 150 as shown by the arrow A is applied to the latch 149 from the tensioned poster 139, Stop 149
Is turned around the shaft hole 145, and the parallel force indicated by the arrow A is converted into a component force B along a straight line connecting the latch 149 and the shaft hole 145 and a component force C in a direction perpendicular to the straight line. This component force C can be divided into L-shaped elastic structures 140.
Is pressed against the frame 150. Therefore, the poster 139 is not detached from the frame 150 even when a slight vibration is applied in a state where the poster 139 is set, and the poster 139 is detached from the frame 150 when a person pulls with a force exceeding the component force C.

Between the lying state and the standing state, there is a state in which the force indicated by the arrow A and the component force B are in the same direction, and the component force C disappears. This state is an unstable state where the component force B is largest and the L-shaped elastic structure 140 can rotate in any direction about the shaft hole 145.

In the fourth and fifth embodiments and the modifications thereof, if a poster is set for the reason described with reference to FIG. 28 in the third embodiment, the poster is unlikely to come off.

In the tension panel of the present invention as described above, a sheet-like display means such as a banner is set in addition to a poster.

In the above-described embodiment, the panel on which the poster and the like are set is a rectangular integrated body such as a rectangle, but may be formed of four separate panel corners. In this case, four panel corners are attached to the ceiling and floor of the room, for example, two each, and the L-shaped holding member and the L-shaped elastic structure are connected with a long string, or the tension fixing means and the holding means are long. The poster or the like may be suspended in the room by connecting with an elastic body.

When a display sheet such as a poster or banner is attached to the panel of each of the above-described embodiments and modified examples and left for 1 hour in an environment of a temperature of 3 ° C. and a relative humidity of 90%, wrinkles and waves are formed. , It was confirmed that no curling occurred.

In the above-described embodiments and modifications, the tension applied to the corner fitting or the holder by the spring is a considerable force of 1 to 2 kg or 3 kg or more, but this corner fitting or the holder is L-shaped. Since the display sheet is held on each surface along two sides forming the corners of the display sheet, the display sheet is not easily broken.
Also, the tension applied to one corner is 90
° and spread on the display sheet, so that wrinkles and waves are hardly generated on the display sheet even if the tension is large. For example, when such a large tension is applied to one corner of the poster by only the spring, wrinkles and waves are generated at the corner of the poster.

In the above-described embodiments and modifications, the tension applied to each corner of the display sheet is usually equalized. However, when the display sheet is quite heavy, the tension at the upper corner is increased to achieve balance. You may. The helical spring or the leaf spring for applying the tension is not limited to a metal spring, and a resin spring such as POM, PSS, or polycarbonate is also used. A resin spring is preferable because it is lightweight, has little fatigue, and does not rust.

As the holding mechanism of the holding means for the corners of the display sheet, there are a mechanism using an adhesive and a mechanism using a clamping force by a spring or the like. The limit of the tension applied to the corner is about 2 to 3 kg. When a tension of 3 kg or more is applied, it is desirable to increase the clamping force to cope with the tension.

The poster as a display sheet set on the tension panel of the present invention is not limited to paper, but may be a resin film. Conventionally, when displaying a poster made of a resin film, the resin film is sandwiched between two transparent acrylic plates in order to spread the resin film. The resin film can be stretched and displayed without using it. In this case, it is needless to say that an aesthetic effect can be exhibited by applying a backlight from the back side of the resin film. Further, FIG.
If a decorative frame as shown in (1) is used, the tension means of the present invention can be used as a panel for a double-sided display since the holding means, the tension fixing means, the elastic body and the like can be covered and made invisible from the outside. it can.
Also, when a banner is set, two banners having different displays may be set on the front and back, or two tension panels on which one banner is set may be stacked back to back.

Further, in the above embodiments and modifications, the magnitude and direction of the tension applied to the display sheet can be adjusted according to the material of the display sheet and the degree of environmental change such as temperature and humidity. Similarly, display sheets having different sizes can be attached so that wrinkles, waves, and the like do not occur. Further, the tension applied to the corners of the display sheet is applied in the direction of a straight line bisecting the inner angle of the display sheet, that is, in the direction of a straight line inclined at 45 ° from one of the two sides constituting the corners of the display sheet. However, even if the angle of inclination is 40 to 50 ° (that is, the angle of inclination from the other side is 50 to 40 °), the balance of the tension applied to the display sheet is not largely disturbed, and the display sheet has wrinkles and waves. , No curling occurs. In addition, rubber straps and bands,
A string or band made of an elastic resin may be used.

The components of the above-described embodiments and modifications are interchangeable. For example, the L-shaped holding member 1 of the third embodiment is interchangeable.
30 can be used in the first and second embodiments.
