According to the screen device of the present invention, a screen sheet made of a flexible member, a plurality of divided base members for holding the screen sheet in a planar shape at the time of use, and the screen sheet A plurality of sticking members having a predetermined thickness for sticking to the base member, wherein the plurality of sticking members are disposed at a predetermined distance from a butt portion of the plurality of base members; A desired gap can be secured in the bent portion of the sheet 1, and the screen device can be folded with good workability without using a spacer and without making a fold on the screen sheet.

Further, by providing the hinge member having elasticity for holding the divided base members so as to be openable and closable, the mounting can be performed at the joint surface, the load on the base member can be reduced, and the hinge portion can be reduced. But not bulky.

Further, since the divided base member and hinge member are made of a resin plate material and are joined by ultrasonic welding, a joining member is not required for attaching the hinge member, and the reliability of joining is improved. In addition, the working time and weight can be reduced.

Further, an engaging portion which can be engaged with each of the base members connected by the hinge member is provided, and by engaging the elastic member which can be extended and contracted, the screen at the time of opening and closing is held so as not to be bulky. be able to.

Further, on the left and right sides of the base member, legs for holding the screen upright are provided, and these legs can be opened and closed, so that the screen is not bulky when folded.

Further, the S-shaped fittings are provided on the legs provided on the left and right sides of the base member, and the left and right legs are opened and closed by sliding the S-shaped fittings. it can.

Further, the provision of the L-shaped bracket on the leg allows the clasp to be formed by simple sheet metal processing.

Further, since the legs are formed integrally with the mounting base member, the left and right legs can be easily formed in the same shape, so that the productivity can be improved and the play during support is eliminated.

Further, since the mounting base member and the legs are integrally formed by sheet metal working, the left and right legs can be easily formed in the same shape, and the support stability during use is improved.

Further, it is formed of a resilient inverted W-shaped support beam detachably engaged with a plurality of base members of which both ends are divided, and is divided so as to hold the screen in a plane when used. By providing the support mechanism for supporting the plurality of base members, a closed shape of the screen sheet can be secured, and when the screen is opened, the shape can be secured as the initial shape of the supporting beam. In addition, since there is no rotating part as a mechanism, it is easy to make, and machining defects are reduced. Further, since the support beam on the screen projection surface is in the direction opened to the front, the viewing angle is widened.

Further, the rigid piece which is rotatably restrained is rotated under the base member at the same time as the opening and closing of the screen sheet to form and house the supporting legs, thereby limiting the position of the screen sheet when folded. With a mechanism, the screen can be installed quickly, and the screen can be held in a non-contact state when folded, so that there is no fold and no load is applied to the screen sheet surface, extending the life of the screen sheet. be able to.
