Abstract: A window shade may include a shade, and each of a top portion and a bottom portion thereof has a mount bar. The shade is installed into a sliding unit through the mount bar on the top portion of the shade, and the mount bar on the bottom portion of the shade is coupled with a weight track. The mount bars on the top portion and the bottom portion of the shade are adapted to enable the shade to horizontally install on a top track of a window curtain and also to enable the weight of the weight track to be evenly distributed on the bottom portion of the shade, thereby smoothing the operation of the shade.

Abstract: A shade roller apparatus is provided to achieve stable attachment of a pull bar to a shading sheet, and reduce the numbers of components and process steps required for the attachment. The pull bar may include a clip portion clipping a front hem of the shading sheet along an entire length of the pull bar, and a bottom wall below the clip portion. While having a front end retained by the clip portion, the shading sheet can wrapped around the pull bar such that the shading sheet sequentially passes over an upper surface and a front surface of the clip portion and then continues along the bottom wall.

Abstract: An improved roman blind includes a shade and a plurality of horizontal support bars mounted along the shade. Each of the support bars has a guide dimensioned to receive a lifting ribbon. The blind includes a lift mechanism to raise and lower the lifting ribbon. An adjustable mounting element mounted to the second end of the lifting ribbon is also provided; the adjustable mounting element including first and second elongated members having opposite first and second ends. The opposite ends of the elongated members are configured to couple the elongated members together and clamp an end of the ribbon between the elongated members, a portion of the ribbon adjacent the second end being wrapped around the coupled elongated members. The adjustable mounting element further includes an elongated lock member which prevents the ribbon from unwrapping off the elongated members, the elongated lock member being mounted to a lowermost support bar.

Abstract: A fabric receiving element for a blind assembly, the fabric receiving element having at least two axially extending slots, each slot defining an opening for receiving blind material, the openings being of different respective widths, the slots including a floor opposite the openings, and wherein the middle portion of the floor of the slot is at a greater distance from the opening than the end portions of the floor of the slot.

Abstract: A pull bar screen apparatus and system in which screen is mechanically attached directly to a pull bar. Weld-less friction-lock cold-joining of screen and pull bar provides an improved pull-bar screen apparatus used in retractable pull screens. The pull bar screen apparatus and system remove the need for attaching a vinyl strip to the screen. Instead, the screen is flattened to retain its form and structural integrity. On one elongated end of the screen, an upper and lower lock bar are placed on either side of the screen. Corrugated ridges in the lock bars pinch the screen and hold it in place. A lock bar casing is placed under pressure around the upper and lower lock bars which hold the lock bars in position and thereby retain the screen.

Abstract: An improved staple-in fabric awning system is provided. The awing has a frame made of ribs with outwardly exposed longitudinally extending staple slots. A fabric canopy covers the frame and is tucked into and secured within the staple slots. A vinyl strip is configured to snap into the staple slots of the awning atop the canopy to span and hide the tucked in portions and cover the staples therein. The vinyl strip is covered at least on its exposed top portion with fabric that may visually blend into the fabric of the canopy or that may visually contrast with the fabric of the canopy. The system includes snap-in and snap-on plastic perimeter flanges and out rod flanges that are mounted on the perimeter ribs and out rods that form a grid on the underside of the awning. The plastic flanges form inwardly projecting lips around the openings of the underside grids that support egg crate ceiling panels to form an aesthetically pleasing underside ceiling of the awning.

Abstract: This invention relates to a device for temporarily connecting the ends of two structures of which at least one is flexible and comprises over its length a bead adapted to be introduced inside a gutter provided along the second structure, wherein the gutter is constituted by an open section inside which are disposed, over the whole of its length, two tongues between which is a gap smaller than the thickness of the bead and which presents a certain flexibility enabling their ends to be moved apart from each other under the action of a pressure, stops being provided inside the gutter in order, on the contrary, to avoid any spacing apart during a traction. The introduction of the bead and removal thereof is obtained by means of a slide element movable along the gutter.

Abstract: A roll bar adapted for attachment along one edge of an awning sheet so that the awning sheet can be retracted around the roll bar or extended away from the roll bar includes a generally cylindrical tubular element having longitudinally extending indentations therein with a generally circular groove in the indentation which is partially defined by a pair of upstanding lips having a space therebetween into which the awning sheet can be inserted. The edge of the awning sheet inserted into the groove has a sleeve formed therein which receives an elongated rod which is larger in diameter than the spacing between the lips so that the rod cooperates with the lips in retaining the edge of the awning sheet in the roll bar. The lips are designed such that the ends thereof can be flared outwardly to facilitate insertion of the awning sheet into the groove without snagging and possibly damaging the awning sheet material.
