Specifically, the display plate of the display device is automatically expanded. The present invention relates to a telescopic structure for a display device that stands up or projects a pop advertising board from the surface of the display device.

Conventionally, a cardboard or cardboard tubular display body on which information such as products has been posted for the purpose of advertising the product at stores, exhibition halls, etc. is provided by an elastic structure provided inside the tubular display body. The cylindrical display body is expanded to be self-supporting on the floor surface when in use, and the tubular display body can be flattened by folding the telescopic structure when not in use. For example, utility model registration No. 3164774 ( Patent Document 1) and Utility Model Registration No. 3163482 (Patent Document 2) have been proposed.
In addition, a display tool capable of projecting a pop advertising board on which information such as a product is projected from the surface of a cardboard or cardboard display body is also used. For example, Japanese Patent Application Laid-Open No. 2011-180320 (Patent Document 3). Has been proposed.

The telescopic structure used for the display for display disclosed in Patent Document 1 has two leg portions that are bent in a substantially square shape and arranged to face each other, and one end portion and the other end portion of both leg portions. Are connected to the front and back plates of the display body for display, and an elastic member for connecting the two leg portions in the vicinity of the bends in the leg portions. Thus, the leg portion of the expansion / contraction structure pushes and expands the cylindrical display body so as to bulge outward in an arc shape so that the display body can be self-supported.
However, the invention of Patent Document 1 does not include a member that regulates the interval between the two leg portions to a predetermined interval in the stretchable structure, so that the interval between the two leg portions is constant. In other words, the width for expanding the display body for display of the cylindrical body in an arc shape outward is not determined. Further, when the stretchable structure is expanded into a three-dimensional shape, the three-dimensional shape becomes unstable. Furthermore, since an elastic member having a strong pulling force cannot be used, there is a problem that the force for expanding and expanding the display body for display in an arc shape is weak.
