The invention is a roller shade tube assembly with a main housing having a lumen divided into two sections by an internal spring stop. The distal end of the main housing has a recessed mounting cavity coupleable to a motor. The proximal end of the main housing has one or more interlocking fingers. A spring inside the proximal lumen abuts the spring stop. An inner guide cylinder is coupled to slide inside the main housing against the spring and coupled to a lumen of an auxiliary housing that is movably coupled to the main housing. The distal end of the auxiliary housing includes one or more complementary interlocking fingers and a second recessed mounting cavity at its proximal end. Wall mounting brackets on each side of the tube assembly are configured to fit into the recessed mounting cavities. A shade fabric is coupled to the roller shade tube assembly.

A mounting system for a roller blind includes a tension bar for mounting under pressure between first and second sides of a windows frame. The tension bar may provide both long and short adjustment of mounting system width. The tension bar extends through a hollow roller tube of the roller blind, and through a clutch mechanism of the roller blind, and is coupled to end mounting fixtures. The length of the tension bar may be adjusted as a long adjustment of mounting width. Various mechanisms may be associated with one or both of the end mounting fixtures for short adjustment of mounting width, such as a latch mechanism, wedge mechanism, spring-loaded mechanism, or turn-buckle system. End pads at the ends of the blind provide friction and absorb excess pressure. The mounting mechanism serves as a universal window blind bracket and support rod, which requires no screws or nails to install.

The present application belongs to the field of spring roller shutters, and particularly relates to a spring roller shutter with adjustable function, which comprises a spring assembly in a drum, an adjusting assembly and a limiting assembly, wherein one end of the drum includes a concentric adjusting cylinder, the adjusting cylinder is connected with an output end of the spring assembly, one end of the adjusting cylinder away from the drum includes a fixed shell, the fixed shell includes a cavity with an opening facing the adjusting cylinder, the one end of the adjusting cylinder slides in the fixed shell, and the adjusting assembly and the limiting assembly are in the fixed shell, thereby achieving the benefit of adjusting the maximum withdrawal height of the curtain.

A mounting element for mounting an architectural covering between two opposing mounting surfaces includes an elongate mounting member having a first end, a second end, and a guide surface. The mounting element also includes a telescopic extender arranged at one of the first end or the second end of the elongate mounting member, with the telescopic extending being operable between a retracted configuration and an extended configuration. The telescopic extender includes a slidable body to slide along the guide surface so as to lengthen the mounting element, and a locking member configured: i) to allow the slidable body to slide in the first translation direction, and ii) to prevent the slidable body from sliding in a second translation direction opposite the first translation direction. In addition, the telescopic extending includes a release mechanism configured to cooperate with the locking member.

An extendable mounting apparatus for a window covering allows blinds or shades to be mounted into a window or door frame of any width. The apparatus includes a mountable headrail, a proximal telescopic rod, a distal telescopic rod, a proximal window covering, and a distal window covering. The mountable headrail is mounted into a window or door frame by adjusting a length of the mountable headrail to be equal to a width of the window or door frame. The proximal telescopic rod and the distal telescopic rod lengthen or shorten in unison with the mountable headrail. The proximal telescopic rod is used to hang the proximal window covering. The distal telescopic rod is used to hang the distal window covering. The proximal telescopic rod and the distal telescopic rod are positioned in such a way that the proximal window covering and the distal window covering overlap each other.

A punch-free mounting assembly and a curtain are provided. The punch-free mounting assembly includes: a housing, a rotating base, and a main body, where the rotating base is partially accommodated in the housing and is rotatably connected to the housing; the rotating base is provided with an axially-through accommodation cavity; the main body is slidably fitted through the accommodation cavity; a limiting member is slidably sleeved on the main body; an outer wall of the limiting member is threadedly connected to an inner wall of the accommodation cavity; a first limiting portion is radially formed outside the main body; the first limiting portion is slidably connected to the accommodation cavity and abuts against one end of the limiting member; and when the rotating base is rotated, the limiting member moves axially along the accommodation cavity until the limiting member is tightly pressed against the first limiting portion.
