The mobile frame is perpendicular to the upper frame portion of the fixed frame and horizontally moves in a frame range thereof. A frame portion at one side of the mobile frame has a first hollow structure. A first upper pulley and a first lower pulley are respectively disposed at a top end and a bottom end of the first hollow structure. The first pull string has two ends which are wound around the first upper pulley and the first lower pulley in a crossover manner. An upper rail and a lower rail are respectively disposed on the upper frame portion and the lower frame portion of the fixed frame. An upper strip and a lower strip are respectively disposed on the upper rail and the lower rail.

A screen guide frame structure and a screen device having same. The present invention mainly comprises providing a passage on the screen guide frame structure. When a screen is stored or unfolded, the passage can allow one end of a windproof hook to slide therein; moreover, since the other end of the windproof hook is hooked onto a net line of the screen, the screen device cannot be blown away from the outside of a guide frame when there are strong winds.

The present invention relates generally to a screen assembly that can be used in a window or door cavity, or any other area which may benefit from the assembly and which contains a flexible sheet like member (for instance an insect screen) wound about substantially vertical rod (for example), which can be pulled across the window or door cavity such that the screen extends and retracts in a horizontal direction and particularly to a system and method allowing more straightforward installation on site, quickly and easily.

A screen device (1), comprising a screen roller (2), a screen (3) which can be rolled up and unrolled hereon, an end lath (4), which is fitted to an opposite side of the screen (3), and a tensioning system (8) to tension the screen (3) in the roll-up and unrolling direction, the tensioning system comprising on each lateral side of the screen (3) a band wheel (5) next to the screen roller (2), a tensioning cord (6), which can be rolled up and unrolled hereon and which, at its end away from the band wheel (5), is fastened to the end lath (4), away from the screen roller (2) a reversing wheel (7), via which the tensioning cord (6) is turned, and a spring sub-system (18), which comprises at least one spring element (9) for keeping the respective tensioning cord (6) under tension, wherein at least one of the spring sub-systems (18) comprises adjustors (10, 11, 14, 13, 16) for adjusting the spring force of the spring element (9).

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.

A screen assembly includes a support structure. A roller assembly is mounted on the support structure. A flexible panel with a distal end is mounted on the roller assembly so that the flexible panel can be wound on to and off the roller assembly as the flexible panel is retracted and extended. Two opposed track assemblies are arranged on the support structure, sides of the flexible panel and each track assembly being configured so that the sides of the flexible panel can slide within the track assemblies as the flexible panel is retracted and extended. At least one of the track assemblies has a static support that is fixed relative to the support structure and a dynamic support that is displaceable relative to the static support. An adjustment mechanism is operatively connected to the static and dynamic supports to adjust a lateral position of the dynamic support relative to the static support. An elongate guide assembly is mounted on a proximal end of the flexible panel to guide movement of the flexible panel with respect to the track assemblies. An adjustment mechanism is operatively connected to the static and dynamic supports to adjust a lateral position of the dynamic support relative to the static support. An insert is mounted on at least one end of the guide assembly. The dynamic support of said at least one of the track assemblies includes a runner in which the insert is received to slide or roll with respect to the dynamic support as the flexible panel is retracted and extended.

A device (1) is described for stopping, releasing and restoring the position of roller-type window nets (3, 48), comprising: a fixing shaft (13) having a coupling groove (15) formed in a front external circumferential surface thereof and an insertion groove (16) formed in a rear surface thereof; a ball rotor (18) inserted into the fixing shaft (13) and coupled to the external circumferential surface of the fixing shaft (13), including a front portion coupled by means of a spring (30) and having a conveying groove (20) formed in a surface thereof for conveying a ball (40) and a guide jaw (38) formed in a central part thereof, wherein the ball (40) is inserted into the conveying groove (20); and an outer rotor (42) coupled to the conveying groove (20) via the ball (40) and having a rotation groove (44) formed in an internal circumferential surface thereof, wherein the ball (40) is coupled to the rotation groove (44) to rotate.

A retractable material enclosure system that can be custom fit to provide a secondary barrier within an opening that is unobtrusive when not in use. The retractable material enclosure system may be used with different types of materials that are capable of being rolled about and retained on a cylinder or other drum type member when they are not extracted and in use. The retractable material enclosure system is particularly useful for providing a custom fit retractable screen door that fits within single or double door opening.

This invention is directed toward a window for a garage door panel, where the window has an opening that is surrounded by a body portion, and can be manufactured as part of the manufacture of a garage door panel, or retrofitted into an existing garage door panel. The window has a sliding door that can be slid open to allow for air ventilation, and has bars so that pets cannot escape through the window when it is open, and some combination of a sliding screen and optional security bars to keep insects out and keep pets in the garage. The optional security bars can be bolted or otherwise attached to the panel, thereby not only strengthening the panel but also making it harder for pets to escape and any burglars to enter.
