Abstract: A roller and an insert plate-assisted roller securing device are provided. The insert plate-assisted roller securing device includes a wheel-shaped cover, an outer cover, and a bracket. The outer cover has a supported portion with different widths in different directions, and the supported portion can be engaged in the bracket without separating from the bracket. As the outer cover can be coupled to the bracket along with the roller by a single person, installation of the roller is made easier and less time-consuming than before.

Abstract: A barrier assembly for preventing items from falling behind domestic appliances and a method of using the same is provided. The barrier assembly provides one or more mesh nets, each mesh net extending between two pivotable columns. Each pivotal column is mounted to spaced apart surfaces along an upper periphery of an appliance. As a result, each independent mesh net may be pivoted to different angles of incident relative to the upper surface of the appliance so as to close off the space between that portion of the periphery of the appliance and an adjacent wall, preventing item from falling therein.

A one way bearing has an inner race secured to the shaft and has an outer race that can freely rotate in only one direction in relation to the inner race. A brake drum is coupled to the outer race. Brake shoes are in operative contact with the brake drum to apply friction to the brake drum when there is relative motion between them. A brake adjuster adjusts the braking force applied by the brake shoes on said brake drum. The one way bearing is arranged to maintain the brake drum stationary in one direction of rotation of the shaft and rotate the brake drum in the opposite direction of rotation resulting in a degree of braking of the shaft as determined by the brake adjuster.

Abstract: A controller assembly includes a housing, first and second tube units, and first and second runners. Each of the first and second runners slides on a respective one of the first and second tube units when the respective one of the first and second tube units is driven to rotate.

In response to sliding of the second runner to bring the second runner into abutment with the first runner, the second runner is prevented from sliding over the first runner, whilst impeding rotation of the second tube unit.

The transmission mechanism includes a first transmission gear meshed with the driving gear, a synchronous gear coaxial with the first transmission gear, and a fixed gear fixed to the shaft and meshed with the synchronous gear. Axial directions of the output shaft and the shaft are vertical, and the synchronous gear and the fixed gear are bevel gears whose axial directions are perpendicular to each other.

Abstract: A retractable screen device for a framed opening employing a frame track fastened to each side support of the framed opening; the frame track forming a compartment for receipt of a guide rail with a decompression gasket positioned between the frame track and the guide rail. A screen mounted on a horizontally disposed rotatable shaft secured to a header of the opening has laterally opposed side edges with an elongated flexible protrusion secured along the length of each side edge. The guide rail receives and guides the screen protrusion along a longitudinal direction, and the decompression gasket allows the guide rail to traverse the frame track side walls to permit the screen to flex while maintaining a consistent tension on the screen. Vertical tension adjustment is provided by use of a biasing member coupled to the center axle that activates when the screen is deployed.

Abstract: The present invention is a method of preparing and assembling certain prefabricated products (identified below as (a) Suspension Rods; (b) Decorative Finished Wood; (c) Locking Pin; and (d) Rubber Gasket) which, once assembled, will serve as a high end room divider or window covering (also known as window treatments). The inventive framework allows the user who is preparing and assembling the product to have an installed room divider or window coverage that is clean, with no marks, and also able to be assembled by one person, as opposed to having multiple parties present to effect installation.

Abstract: A roller blind is disclosed which provides horizontal slats for directional shading, enabling the application of a screen fabric which allows a greater portion of visible light to pass therethrough. The disclosed slatted roller blind is free from the usage of ladder cords and is simplistic in design. The disclosed slatted roller blind maintains a compact formation of a roller shade when retracted and has greater resistance to skewing along the longitudinal axis of the roller while being retracted. Furthermore, the disclosed slatted roller blind design is capable of being utilized as an outdoor or indoor blind.

Abstract: Examples of rail assemblies for architectural coverings disclosed herein stabilize motor assemblies via end caps to reduce transfers of vibrational motor forces to the rails. An example rail for an architectural covering includes a housing, a motor to be disposed in the housing, and an end cap to be coupled to said housing. The example rail includes a track defined in an exterior face of the rail. A first portion of the end cap is to be received in the track. The end cap is capable of at least two degrees of freedom of motion relative to the housing prior to the first portion being received in the track. In the example rail, the track is to restrict the at least two degrees of freedom of motion of the end cap when the first portion of the end cap is received in the track.

Abstract: A window blind includes a headrail, a covering assembly including a plurality of slats and a bottom rail, a lifting mechanism including a driving module and a lift cord assembly operably connected to the driving module, a tilt mechanism adapted to drive the slats to rotate, and an auxiliary unit provided between the tilt mechanism and the lifting mechanism. The lift cord assembly is connected to the bottom rail for expanding or folding the covering assembly. The covering assembly is in a first state when each and every one of the slats is substantially parallel to each other and correspondingly rotatable by the tilt mechanism, and is in a second state otherwise. When the covering assembly is in the second state, the auxiliary unit is drivable by the tilt mechanism to make the lifting mechanism further release the lift cord assembly, changing the covering assembly into the first state again.

Abstract: A wand assembly for use with an architectural-structure covering is disclosed. The wand assembly may include a first operating element (e.g., an operating cord) for moving the covering between extended and retracted positions and a second operating element (e.g., a tilt wand) for adjusting rotation of the covering between open and closed configurations. The first and second operating elements are coupled to a handle assembly via separate and distinct coupling mechanisms so that manipulation of the second operating element does not affect the first operating element thereby preventing twisting of the first operating element about the second operating element. The wand assembly may include a first, inner rotatable wand and a second, stationary outer wand. The inner wand is rotatable relative to the outer wand so that rotation of the inner wand does not rotate the outer wand, and hence the first operating element coupled to the outer wand.
