Description

The present invention relates to a telescopic structure for a display device.

Patent Document 1 describes a telescoping structure for a display device (hereinafter simply referred to as a telescoping structure) that automatically expands the display device or causes a pop-up billboard to protrude from the surface of the display device.
The expandable structure described in Patent Document 1 includes a cylindrical body, an elastic member, an adjustment plate, and a locking member.

The cylindrical body includes two leg plate portions facing each other, a first flat plate portion, and a second flat plate portion. The elastic member is composed of a rubber ring or a rubber string, and pulls the two leg plates in a direction toward each other. The adjustment plate is held between the two leg plates by an elastic member. The adjusting plate is separated from the cylindrical body and is located between the bent portions of the two leg plate portions. Both end portions of the adjustment plate are configured to be able to abut on the inner surfaces of the two bent portions, respectively. The elastic member is inserted into a through hole provided in the adjustment plate. Both ends of the elastic member are inserted into through holes provided in the bent portions of the two leg plates, and are respectively locked by two locking members on the outside of the cylindrical body.
