Embodiment Construction

[0020] Figure 1A to Figure 1C An exemplary window treatment in the form of a motorized roller shade 100 is depicted. Motorized roller shade 100 can be configured to be installed in front of a large opening (eg, one or more windows spanning 8 feet or more in width), for example, to prevent sunlight from entering the space and / or to provide privacy. The motorized roller shade 100 may be mounted to a structure (eg, a window frame, wall, or other structure) proximate the opening. As shown, the motorized roller shade 100 includes a shade assembly 110 , a battery box 130 , and a housing 140 that may be configured to support the shade assembly 110 and the battery box 130 . The housing 140 may be configured as a mounting structure and / or a support structure for one or more components of the motorized roller shade 100 .

[0021] As shown, the housing 140 includes a rail 142 , a first housing bracket 150 and a second housing bracket 160 . The track 142 is shown elongated between a f...

Abstract

A low-deflection roller tube of a motorized roller shade may include a first tube and a second tube that is attached to the first tube. The first tube may be configured to operably couple to the motordrive unit of the roller shade. The second tube may comprise a plurality of carbon fiber layers additively constructed on the first tube, and may be fabricated such that first and second longitudinalportions of the roller tube exhibit different material stiffness characteristics from each other. The first and second portions of the roller tube may be made of carbon fiber material having different tensile moduli. Layers of carbon fiber material in the first portion of the roller tube may be staggered with layers of carbon fiber material in the second portion of the roller tube at an interfaceof the first and second portions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 502,968, filed May 8, 2017, which is hereby incorporated by reference in its entirety. Background technique [0003] Window treatments may be installed in front of one or more windows to, for example, prevent sunlight from entering a space and / or provide privacy. Window treatments may, for example, include roller blinds, Roman shades, Venetian blinds, or draperies. Roller shades generally include a flexible shade fabric wrapped around an elongated roller tube. Such roller shades may include a weighted hemming strip at the lower end of the shade fabric. The hemming strip may allow the shade fabric to be hung in front of the window or windows in front of which the roller shade is mounted. [0004] Advances in window construction techniques have enabled the manufacture of windows of ever increasing size, such as may be 8 feet or wider. Such l...
