The present invention consists of aluminium framework for the manufacture of doors or windows, which is applied in a door or window opening of a building. It comprises at least one fixed frame (1) and fixed or movable panels (4) which have central (6) and reinforcing (5) props, handles (3) (7), anti-pollen/mosquito net (9) winder integrated into a profile (10). It has a locking system (2) of the panels (4), which is integrated in the aluminium profiles of the fixed frame (1); a locking system (8) of the anti-pollen/mosquito net (9) allowing the profile (11) of the net (9) to be attached to the handle (7). The movements of the net (9) and the panels (4) can be performed either manually or automatically, in both cases this movement being facilitated by a slide rule (13) with integrated bearings.

The chain consists of a plurality of rigid chain links and of a flexible traction means that connects the chain links. Said flexible traction means is a ball string that consists of a string and of balls arranged thereon at intervals, and said balls are pressed into openings of said chain links.

A longitudinal adjuster 10 that forms a free end 61 of the first guide 6, to which a weight 101 is attached, and which moves in an inside of the slidable frame in a Z-axis direction is connected to a first guide unit 63 that is positioned at the other end in the Z-axis direction of the first guide 6.

A linear notch 103c is formed on an extension line of a rail part 63g of the first guide unit 63 to which the adjuster 10 is connected at each of inner side surfaces in an opposite direction of both of the first stoppers 103. A stopping unit 64 is connected to the first guide unit 63 that exists at a position corresponding to the other end in an X-axis direction in a drawn portion 62 of the first guide 6, and a stopping unit 64 is the same as the first guide unit 63 except that a supporting piece 63h is removed and a second stopper 64a extending from each of the rail parts 63g to the other end in the Z-axis direction of each of the side walls 63a is provided at a connected end to the first guide unit 63.

A tension member 8 formed into a loop is disposed in a Z-axis direction, an inside of a slidable frame 2 is divided into a first storage portion 22 for storing a first guide 6 at one side in the X-axis direction and a second storage portion 23 for storing a second guide 7 at the other side in the X-axis direction, both the first storage portion 22 and the second storage portion 23 allow the tension member 8 to pass, a direction changing member 15 on which the tension member 8 is hung and which causes a direction of the tension member 8 to change in the Z-axis direction is provided in each of the insides of one end portion and the other end portion in the Z-axis direction of the slidable frame 2, one of the direction changing members 15 is disposed through a supporting member 16 at one end portion in the Z-axis direction of the first storage portion 22, a pair of relieving pieces 16a.sub.2, 16a.sub.2 extending in the Z-axis direction and opposing to each other in a Y-axis direction are provided with the supporting member 16, and each of the relieving pieces 16a.sub.2 comes into contact with needle-like parts 92 of each of screen retaining members 9 and causes the needle-like parts 92 to bend so as to move away from the supporting member 16 in a Y-axis direction when the first guide 6 is drawn from and stored in the first storage portion 22.

A connector 11 which is connected to a second guide unit 73 positioned at one end in a Z-axis direction of a second guide 7 stored in a second storage portion 23 of a slidable frame 2, forms a free end 71, and is longitudinal in an X-axis direction has a female part 111 and a male part 112 that is fixable to and separate from the female part 111, the female part 111 has, at the other end portion in the Z-axis direction, a pair of connecting pieces 111b opposing to each other in a Y-axis direction, in which a third opening 111a, in which each of second pins 73c of a second guide unit 73 is loosely fitted, is opened, a fourth opening 111c for fastening is opened in the X-axis direction at one end portion in the Z-axis direction of the female part 111 and a hollow receiving portion 111d extending in the Z-axis direction is formed in the female part 111, the male part 112 is storable in the receiving portion 111d of the female part 111, one end and the other end of a tension member 8 are fixed to the male part 112, and a fixing piece 112b, in which a fifth opening 112a capable of communicating with the fourth opening 111c of the female part 111 is opened in the X-axis direction, extends from one end portion in the Z-axis direction to one side of in the Z-axis direction in the male part 112.

A pull across screen assembly has a flexible screen member (e.g. flymesh) wound about a vertical rod positioned at one side of the opening. A line member arrangement is attached to the front of the screen member and part of the line member winds about a tapered drum which is positioned on top of rod and which rotates with rotation of the rod. The arrangement allows the screen member to be tensioned and also to be balanced as it is pulled across the opening.

A system comprising: a sliding shield equipped with horizontally sliding cloth movable by means of a handle bar between a lateral box and a closure upright, and a guiding and tensioning retractable device for sliding shields comprising a plurality of first guiding modules and a plurality of second guiding modules, consecutively and alternately coupled between them forming a guiding body foldable and insertable within the handle bar and comprising a first terminal end fixable to the lateral box and a second terminal end adapted to be free of sliding within the handle bar, the first guiding modules and the second guiding modules being interposable between the handle bar and the lateral box.

The sliding shield comprises at least a lower pocket and the guiding and tensioning retractable device comprises at least a tensioning element provided with a first end anchored to the second terminal end and a second free end inserted within the lower pocket.

A deployable window cover module includes a cover material mounted on a tensioned roller located in the window frame housing. The deployable cover material may be attached to the sash or outer part of the window and, as such, is unrolled as the window is slid open. The housing may be located in the base or top of the window frame or in the sides of the window frame.

There is provided a screen device that is capable of preventing deformation such as loosening of a horizontally-sliding roll screen due to the weight of the screen. A guide member has a slit that allows a fastener-like member at an upper end of the screen to be slidably engaged therewith in a retained state. In a state in which a space, which allows bending in the vertical direction, is formed above the guide member, both end portions and of the guide member are fixed to an upper horizontal frame of a screen frame, flange portions of the guide member are positioned above protruding walls in the upper horizontal frame, and spring members that apply upward urging forces to the guide member are provided between the protruding walls and the flange portions. Thus, deformation of the screen due to the weight thereof is suppressed by using the guide member.

A screen device includes a cylinder body, a movable frame and two first frame materials, wherein the cylinder body and the movable frame are disposed between the two first frame materials, and a rolling bar is disposed in the cylinder body; a screen is disposed between the rolling bar and the movable frame, and at least one rotating member is disposed in the cylinder body; at least one pull line penetrates the movable frame, and at least one end of the pull line penetrates the first frame material to extend into the cylinder body, and is then combined to the rotating member; the rotating member is disposed on a side portion of the cylinder body, and therefore, the rotating member can be adjusted and controlled only by using a tool on the side portion of the cylinder body, so as to adjust and control the tightness of the pull line when needed. The process thereof is completely free from blockages caused by any component, and adjustment and control is really convenient.
