A window includes a window frame and a screen mounting assembly. The window frame is formed with two rail slots. The screen mounting assembly is adapted to be connected to a window screen and includes a roller unit, a sliding unit and an interconnecting unit. The roller unit includes a roller seat. The sliding unit is slidable along the rail slots and defines an engaging groove. The interconnecting unit is operable between a disengaging state where the interconnecting unit is connected to the roller seat, and an engaging state where the interconnecting unit is separated from the roller seat and inserted into the engaging groove so as to engage the sliding unit, such that movement of the sliding unit along the rail slots results in winding and unwinding of the window screen.

A brake arrangement, for a retractable screen arrangement in which the a screen roller applies a retraction force to the screen and brake arrangement, includes a brake arrangement, for providing a braking force between the brake arrangement and a track which guides the brake arrangement, to resist retraction. The brake arrangement provides a brake member with a friction surface for contacting the bearing surface; a brake member support for supporting the brake member; and a forcing arrangement for forcing the friction surface against the bearing surface. The forcing arrangement includes a biasing arrangement for biasing the friction surface onto the bearing surface, and a force-increasing arrangement for increasing the force with which the friction surface engages the bearing surface. The force increasing arrangement converts a frictional force between the friction surface and the track into additional contact pressure force of the friction surface onto the guide track.

A hidden insect screen system for tilt-to-clean, double hung windows whereby raising the bottom sash (104) causes resultant opening to fill with insect screen (115a) dispensed from an ordinary self-storing roller mechanism (114) mounted inside bottom rail (109) of said sash and whereby lowering the upper sash (105) causes resultant opening to fill with insect screen (115b) dispensed from an ordinary self-storing roller mechanism (122) mounted inside window head frame (103), all furnished such that vertical edges of the screens are protected from insect passage by contacting weatherstrip-like edge seals (127), and arranged such that insect protection is maintained with minimal interruption when each sash is tilted and its glazing is cleaned, the lower end of the upper screen being attached so as to be quickly repositioned from top to bottom of said upper sash.

A modular enclosure structure having at least three walls and comprised of at least three elongated posts selected from at least two elongated upright/vertical posts. Each post has a longitudinal hollow a flexible and durable compacted sheet material therein and wherein a narrow longitudinal through-slot aligned with the free end of each of the compacted sheet materials. Sheet material in each hollow is able to be externally drawn and retracted with manipulation of the free end. The free end of each sheet material has a latching member attached to either an elongated upright/vertical post member, having at least two latching members or to the two elongated posts having hollows and also cooperative latching members, wherein walls of sheet material are externally drawn from the posts with compacted sheet material to form an enclosure comprising at least three walls of sheet material.

A mosquito net of a compartment of an access of a vehicle with a floor and a riser includes a frame and a curtain connected to the frame. The frame includes a first vertical upright, a top rail and a bottom rail configured to be secured to the vehicle, and a second upright free to slide on the top rail and bottom rail.
