Embodiment Construction

[0043] figure 1 An example window treatment system 100 is depicted that includes a spool barrel 110 and a flexible material 120 attached to the spool barrel 110 in a wrapping fashion. Window treatment system 100 includes one or more (eg, two) mounting brackets 130 configured to couple to or otherwise mount to a structure. For example, each mounting bracket 130 can be configured to be mounted to (e.g., attached to) a window frame, wall, or other structure such that the window treatment system 100 is adjacent to (e.g., over or on) an opening such as a window. in the opening) installed. The reel drum 110 may be a rotating member that is elongated in the longitudinal direction L and is rotatably mounted (eg, rotatably supported) by the mounting bracket 130 . The spool barrel 110 may define a longitudinal axis 112 . The longitudinal axis 112 may extend along a longitudinal direction L. As shown in FIG. The flexible material 120 may be attached to the spool barrel 110 in a windi...

Abstract

This invention relates to window treatment edge strips. A hemming strip may define front and rear portions configured to slidably engage one another. When slidably engaged, the front and rear portions may define a slot configured to receive a piece of fabric. The front and back can be configured to hold the fabric piece within the slot. The front and rear can be configured such that the width of the slot is adjustable. The front portion may define a first attachment surface, and the rear portion may define a second attachment surface. The first attachment surface may define a rib. The second attachment surface may define a groove configured to receive the rib when the front portion is slidably engaged with the rear portion such that the fabric piece is clamped within the slot.

Description

Background technique [0001] Window treatments may be installed in front of one or more windows, for example, to prevent sunlight from entering the space and / or to provide privacy. Window treatments may include, for example, roller blinds, Roman shades, Venetian blinds, or draperies. Roller shades typically include a flexible shade fabric wound onto an elongated spool drum. Such roller shades may include a weighted hemming strip at the lower end of the shade fabric. A hembar may allow the shade fabric to be hung in front of one or more windows over which the roller shade is mounted. [0002] Typical hemming strips can weight the lower end of the shade fabric to limit wrinkling of the shade fabric and facilitate smooth operation of the shade as the shade fabric is wound and unwound from the roller drum. A typical hemming strip may use one or more of a variety of attachment means to secure the shade fabric to the hemming strip, including the use of adhesives and staples. [0...
