Adjustable Alignment Bracket for Multi-Tube Roller Blind Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and alignment of multiple roller tubes in roller blinds are challenging due to misalignment of end and middle brackets, leading to difficulties in installation and operation, and misalignment of blind fabrics resulting in a less than desirable visual appearance.
Innovation Solution
The introduction of an alignment bracket with a base portion and a roller tube support surface, featuring a slot and tongue mechanism for adjustable alignment, and a blind fabric alignment device with a drive coupling body and torque transfer mechanism to adjust the rotational position of roller tubes, facilitating precise alignment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple roller tubes are mounted end-to-end with standard brackets, then the blind can cover larger windows, but installation becomes increasingly difficult and laborious
Solution Approach 1:
The middle bracket is designed with adjustable components that allow installation personnel to modify the position and orientation of the bracket during installation. This dynamic adjustment capability enables the bracket to accommodate misalignments between roller tubes, significantly easing the installation process for multi-tube blinds while maintaining support for large window areas
2Area of stationary object
If middle brackets are used to support multiple roller tubes, then the blind can be installed on larger windows, but misalignment of brackets causes installation difficulties and requires repositioning
Solution Approach 1:
The middle bracket incorporates adjustable elements that allow installation personnel to fine-tune the position and orientation during the installation process, enabling compensation for misalignments between roller tubes and end brackets without requiring precise pre-alignment or repositioning operations
Solution Approach 2:
The bracket design allows for adjustment of key geometric parameters such as position and orientation during installation, enabling the system to adapt to variations in roller tube alignment and achieve proper installation without requiring high precision in the initial positioning
3Productivity
If blind fabric is wound on adjacent roller tubes with slight position differences, then the blind can be installed, but the bottom bars become misaligned causing poor visual appearance
Solution Approach 1:
The drive coupling mechanism includes an adjuster that allows the relative rotational position of adjacent roller tubes to be modified after installation. This enables installation personnel to align the bottom bars of blind fabrics from different roller tubes without requiring precise initial winding, maintaining installation speed while achieving desirable visual appearance

AI summary
An alignment bracket for a roller blind, comprising a base and a roller tube support securable to the base. First and second coupling members on the base and roller tube support permit an adjustment of the alignment of the roller tube support, and the end of a roller tube mounted thereon, relative to the base. Also provided is a blind fabric alignment device for a roller tube of a multi-tube roller blind. The alignment device comprises a drive coupling body securable to an end of a roller tube of the blind, a driven member mounted to the drive coupling body, a torque transfer mechanism secured to the driven member, and an adjuster. The torque transfer mechanism transfers rotational torque from the driven member to the drive coupling body through the adjuster. The adjuster permits an alteration of the rotational position of the driven member relative to the drive coupling body.
