A screen device includes a screen retaining member defined by needle-shaped parts attached, in intervals, to a longitudinal base part which is bendable in a pivotally movable direction of each of plural guide units. In an attached condition of the screen retaining member, the longitudinal base part is supported between a rail part and a supporting piece of each of the guide units and all of the needle-shaped parts protrude inwardly between opposing side walls of each of the guide units.

A flexible screen material can be cut out of square, or part of the screen frame can be formed out of square such that when the screen is fitted to the screen frame, there is less sagging.

A braking device for an automatic winding type screen device that stably brakes the automatic winding of a screen regardless of the temperature. The braking device comprises: a housing that is provided inside a winding shaft so as to be able to turn with the winding shaft to wind up a screen; a sleeve that is inserted into the housing and is mounted to a bracket so as not to be able to turn; and a mobile element that can rotate with the housing. A first spring and a second spring are provided on the outer side of the sleeve so as to have the mobile element therebetween. The mobile element twists forward on the sleeve along with rotation of the housing, and biasing forces of the first spring and the second spring that expand and contact with the forward twist of the mobile element brakes the rotation of the winding shaft.

In a screen device, a screen retaining member formed by detachably attaching a plurality of needle-like parts in intervals to a longitudinal base part which is bendable in a pivotally moving direction of each of the first guide units, and in an attached condition of the screen retaining member, the base part is supported between the rail part and the supporting piece of each of the first guide units and all of the needle-like parts protrude inwardly between opposing side walls of each of the first guide units.

The present disclosure is directed to a window screen system for use with casement, hopper, awning, utility window designs to prevent dirt, debris, and insects from entering into the interior of the unit. The system can be installed on existing window frames to provide screen protection only when the window is open and a screen is needed. As such, a user can have a clear view out of the glass window without the unsightliness, distortion, or solar blockage that a traditional “always visible” screen causes.

A mounting arrangement comprised of a first component for attachment to a support, and a second component supportable by the first component. The first component has a first side which is in use distal from the second component and provides a supporting portion spaced from the first side. The second component provides an engagement portion for engagement with the supporting portion. The mounting arrangement provides a restraining part moveable between a restraining configuration for restraining disengagement of the engagement portion from the supporting portion, and a release configuration for allowing disengagement of the engagement portion from the supporting portion. The mounting arrangement further provides a securing component which is insertable between the second component and the first side of the first component to restrict disengagement of the engagement portion from the supporting portion.
