Aspects of the embodiments relate to shades, and more particularly to systems, methods, and modes for a roller shade for a non-rectangular window, such as trapezoidal, parallelogram, as well as other regular or irregular quadrilateral shaped windows, and which may be mounted in different orientations and tilt angles.
Roller shades are effective in screening windows, doors, or the like, to achieve privacy and thermal effects. A roller shade typically includes a rectangular shade material, such as fabric, attached at its top end to a cylindrical rotating tube, called a roller tube, and at an opposite bottom end to a hem bar. The shade material is wrapped around the roller tube. The roller tube is rotated, either manually or via an electric motor, in a first direction to roll down the shade material to cover a window and in a second direction to roll up the shade material to uncover the window.
While windows are typically rectangular and positioned in a vertical orientation, some buildings employ odd shaped windows, such as trapezoidal or parallelogram windows, with tilted orientation. In such applications, typical roller shades with rectangular fabrics are inappropriate as they will not provide full coverage of the window, resulting in unsightly light gaps at the sides of the window. In addition, in typical roller shades, the bottom end of the fabric is free hanging such that the fabric will roll up and down perpendicular to the floor or the window sill. In tilted windows, however, it is desirous to have the shade material to hang and travel parallel to the window such that the fabric is sloped at the same angle as the window. Conventional window shades cannot fully conform to the uniquely shape and angled windows, such as trapezoidal or parallelogram windows.
Accordingly, a need has arisen for a roller shade for a non-rectangular window, such as a trapezoidal, parallelogram, as well as other regular or irregular quadrilateral shaped windows, and which may be mounted in different orientations and tilt angles.
It is an object of the embodiments to substantially solve at least the problems and/or disadvantages discussed above, and to provide at least one or more of the advantages described below.
It is therefore a general aspect of the embodiments to provide systems, methods, and modes for a roller shade for a non-rectangular window, such as a trapezoidal, parallelogram, as well as other regular or irregular quadrilateral shaped windows, and which may be mounted in different orientations and tilt angles.

The hem bar 802 comprises a similar configuration as hem bar 102 discussed above including a housing 820 having a first and second open end 805a and 805b with first and second extendable arms 821 and 822 retractably extending therefrom. Each arm 821 and 822 may comprise a wheel 830 proximate to its first end 823 and a gear rack 825 proximate to its second end 824. The hem bar 802 may comprise a synchronizing mechanism, as discussed above, including an idler gear 826 rotating about a pinion 827 and having teeth that engage the teeth of the gear racks 825 of the pair of arms 821 and 822. The idler gear 826 and the pair of gear racks 825 cooperatively act as a synchronizing mechanism to synchronize the distance the arms 821 and 822 extend out of the side openings 805a-b of the hem bar housing 820. A plurality of rollers 835 may be rotatably disposed within the hem bar housing 820 about the longitudinal sides of the arms 821 and 822 to guide the arms 821 and 822 out of and into the housing 820 to ensure that arms 821 and 822 extend and retract with minimal friction.
The roller shade 800 may further comprise a pair of side channels 828, similar to side channels 128, each secured to and parallel with respective side jambs 811 and 812. Side channels 828 may comprise an L shaped or a U shaped cross section. Each side channel 828 receives therein the first end 823 of a respective arm 821 and 822 to conceal it from view. Each side channel 828 comprises a track 829, with similar configuration as track 129, adapted to retain a respective wheel 830 therein. As discussed above, tracks 829 are adapted to guide the hem bar 802 and shade material 804 along the window frame 810 and control the extension of arms 821 and 822 of the hem bar 802 as the shade material 804 is rolled or unrolled from the roller tube 801. Although according to another embodiment, since side jambs 811 and 812 are parallel such that the distance between them does not change, the hem bar 802 may comprise a single non-expandable longitudinal body, which may be directly attached to the lower end of the shade material 804, and which comprising wheels 830 disposed at its opposite ends that travel within tracks 829 of side channels 828.
Roller shade 800 further comprises a pair of tension modules 841 and 842 with similar configuration to tension modules 141 and 142 each comprising a retractable cord or cable 840 wound about cable mandrel 844 and biased via a constant force spring 845. Tension modules 841 and 842 may be secured to the sill 816 across and opposite from the roller tube 801. Tension modules 841 and 842 may be encapsulated and hidden by a second fascia 843 adapted to be secured to the window frame 810. The second fascia 843 may contain a pair of holes 847 through which the cables 840 retractably extend. Second fascia 843 may comprise longitudinal body secured parallel to the sill 816. According to various embodiments, second fascia 843 may comprise an L shaped, U shaped, or a rectangular cross section. The first fascia 817, the second fascia 843, and the pair of side channels 828 may be seamlessly installed parallel to respective head jamb 813, side jambs 811 and 812, and sill 816 of the window frame 810 in an interconnected or single unit configuration to conceal the mechanical components of the roller shade 800 from view. Each extending terminal end of the cables 840 may be anchored or attached to a respective first end 823 of the respective first and second arms 821 and 822. As discussed above, tension modules 841 and 842 provide tension on the wheels 830, which translates to the hem bar 802 to pull the second end 807 of the shade material 804 with respect to the roller tube 801 such that it hangs straight, without buckling or rippling.
The parallelogram shaped window frame 810 may comprise a head jamb 813 parallel to a sill 816 and the horizontal plane. However, head jamb 813 and sill 816 need not be parallel to each other and need not be parallel to the horizontal plane. The window frame 810 further comprises two parallel side jambs 811 and 812. Although as shown above, the roller shade of the present embodiments may be adopted in a window frame containing non-paralleled side jambs. In the shown window frame 810, side jams 811 and 812 may be skewed by an acute angle 851 with respect to the head jamb 813 and sill 816. The window frame 810 may be oriented orthogonal to the building floor, or in other embodiments, the window frame 810 may be tilted or inclined away from or towards a room.
According to one embodiment, the roller tube 801 may be mounted between the pair of side jambs 811 and 812 in proximity of the head jamb 813 via a pair of shade mounting brackets. In other embodiments, the roller tube 801 may be mounted on a wall, in front of the frame enclosing a window, a door, an opening, or the like. According to an embodiment, the roller tube 801 may be mounted perpendicular to the side channels 828 and the side jambs 811 and 812—i.e., the longitudinal body of the roller tube 801 is mounted at a right angle 850 with respect to the side channels 828 and side jambs 811 and 812. However, in a window frame where the side jambs are not parallel to each other, angle 850 may differ. Essentially the roller tube 801 is mounted substantially perpendicular to the desired direction of travel 831. This results in the roller tube 801 to be mounted at an angle, such as acute angle 852, with respect to the head jamb 813 of the window frame 810. To hide the tilt of the roller tube 801 with respect to the head jamb 813, the roller tube 801 may be concealed from view via a first fascia 817, which may be secured to the mounting brackets or to the head jamb 813. The first fascia 817 may comprise an L shaped, U shaped, or similarly shaped cross section with an opening from which the shade material 804 extends out of the fascia 817. First fascia 817 may comprise a longitudinal and rectangular body parallel to the head jamb 813 of the window. In
According to an embodiment, shade material 804 may comprise a shape that corresponds to the opening of the window frame 810 such that shade material 804 substantially covers the entire opening when it is unrolled from the roller tube 801 as shown in
As discussed above, roller shade 800 may be mounted in a top down configuration in window frame 810 by attaching the roller tube 801 proximate to the head jamb 813 and the tension modules 841 and 842 proximate to the sill 816. Alternatively, the roller shade 800 may be mounted in a bottom up configuration by attaching the roller tube 801 proximate to the sill 816 and the tension modules 841 and 842 to the head jamb 813. Sideway configurations are also contemplated by the present embodiments.
