Patent number: 8839841Abstract: A mounting system for an architectural covering including a pair of mounting brackets, a roller operably connected to each of the mounting brackets, and an end plug at least partially received within the roller and operably connected to one of the mounting brackets. The end plug selectively transitions between an extended position and a retracted position and includes a sleeve, a plunger received within the sleeve, and a spring at least partially received within the plunger for biasing the plunger away from the sleeve. The plunger includes a center or body section and at least two radially spaced tongues extending from a first end of the center section. In the extended position a first portion of the plunger projects from the sleeve and in the retracted position at least a portion of the first portion of the plunger is received within the sleeve.Type: GrantFiled: April 10, 2012Date of Patent: September 23, 2014Assignee: Hunter Douglas Industries BVInventors: Lars Koop, Jörg Bohlen

Patent number: 8776861Abstract: A roller blind including a roller of having a roller length and a roller outer diameter, a fabric attached to said roller for winding and unwinding from said roller. The fabric has a fabric length, a fabric weight, a fabric height, and fabric thickness. The blind includes a bottom bar having a bottom bar weight, and at least one spring operatively connected to the roller to drivingly rotate the roller in at least one direction of rotation. The spring is selected according to a Protocol such that it's length ensures that it drives the roller with a constant operating force.Type: GrantFiled: February 4, 2010Date of Patent: July 15, 2014Assignee: Hunter Douglas Industries BVInventors: Jorg Bohlen, Lars Koop
