Patent ID: 10162255

Abstract:
A low-cost screen apparatus capable of realizing, with its simple mechanism, a method of obtaining flatness of a screen body that has been difficult to realize with expansion using an upper and lower crossbar for support. A holding member 11 holding an upper end of a screen body is provided inside a tubular crossbar provided to the upper end of the screen body. The holding member 11 is formed of at least three divisions including: a left-end-part holding member 12 that holds a left end part of the screen body and pulls the screen body toward a left end of the crossbar; a right-end-part holding member 13 that holds a right end part of the screen body and pulls the screen body toward a right end of the crossbar; and a central-part holding member 14 that is disposed between the left-end-part holding member 12 and the right-end-part holding member 13 and holds a central part of the screen body.
