Abstract
A screen is mounted between a pair of screen mounting frames, at least one of which is slidable. One or more sliding guide frames are disposed near an end of the screen which is not mounted to the screen mounting frames. Each sliding guide frame is formed by connecting rigid units, each of which has a pair of sidewalls and a bridging portion, and thereby each sliding guide frame has rigidity and a bending ability. The sliding guide frame also has at least a free end at one end and is capable of being received in and withdrawn from inside one of the screen mounting frames. A stopper mechanism provided for the rigid units preserves straightness of a withdrawn portion of each sliding guide frame.
Claims14
A screen device, comprising:
- first and second opposing frame portions translatable relative to one another;
- a screen, having opposing first and second edges, positioned between said first and second frame portions;
- and
- a first guide frame portion attached to one of said first and second edges of said screen, wherein said first guide frame portion includes a plurality of rigid units each having first and second sidewalls, with adjacent ones of said plurality of rigid units being rotatably connected together about an axis passing through the first and second sidewalls of one of said adjacent ones of said plurality of rigid units,
- such that as said first frame portion is translated relative to said second frame portion said screen and said first guide frame portion correspondingly move, wherein said one of said adjacent ones of said plurality of rigid units rotates about said axis relative to the rigid unit to which said one of said adjacent ones of said plurality of rigid units is rotatably connected, whereby said first guide frame portion moves along a curved path.
The screen device according to clam 7, wherein said tensioning member crosses over itself loops around portions of said second frame portion.
