Telescoping Door Bracket Integrating Rollers and Pulleys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding and telescoping door hardware requires multiple hanger brackets and pulleys, which complicates installation and increases the number of components needed for operation.
Innovation Solution
A single bracket integrates roller mechanisms and pulleys with an endless cable system to facilitate the movement of door panels along a guide track, allowing for telescoping functionality with reduced hardware requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple hanger brackets and pulleys are used for conventional sliding and telescoping door hardware, then the door system achieves proper functionality for panel movement and telescoping operation, but the device complexity and number of components increases
Solution Approach 1:
The patent combines multiple separate hardware components (hanger brackets, pulleys, and mounting elements) into a single integrated bracket assembly. This consolidation maintains all necessary functions for door panel movement and telescoping operation while reducing the total number of discrete parts that need to be installed and managed.
Solution Approach 2:
The integrated bracket serves multiple functions simultaneously: it acts as a mounting bracket, incorporates roller mechanisms for door panel movement, includes pulleys for cable routing, and provides attachment points for the endless cable system. This multi-functionality eliminates the need for separate specialized components.
2Reliability
If multiple hanger brackets and pulleys are installed on door panels, then the door system achieves proper telescoping operation, but the installation process becomes more time-consuming and complex
Solution Approach 1:
By merging multiple installation steps and components into a single pre-assembled bracket unit, the patent reduces the number of separate installation operations required. The integrated design allows installers to mount one component rather than coordinating multiple separate bracket and pulley installations.
Solution Approach 2:
The bracket assembly is pre-configured with roller mechanisms, pulleys, and cable attachment points assembled together before installation. This preliminary assembly of sub-components into an integrated unit simplifies the final installation process and reduces on-site assembly time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the installation process by combining multiple hardware components into one bracket, reducing the complexity and time required for setting up sliding and telescoping door systems while maintaining efficient panel movement.
Implementation Method 1
At least one roller mechanism is secured to the bracket and to each of the door panels other than the at least one door panel. The at least one roller mechanisms are slidably received within the upper guide track.
Implementation Method 2
A pair of pulleys is secured to the bracket in a spaced relationship, the pair of pulleys carrying an endless cable for rotation around the pulleys.

AI summary
A sliding door assembly comprises a plurality of door panels for coordinated movement along an upper guide track. A bracket is mounted to the upper end of one of the door panels. The bracket comprises an elongated member and defines a plurality of openings for receiving fasteners and roller mechanisms. At least one roller mechanism is secured to each of the door panels and slidably received within the upper guide track. A pair of pulleys is secured to the bracket for carrying an endless cable and the door panels are secured to the cable. In a fully open position, a first outer door panel of the door panels is secured to the cable of the immediately adjacent door panel at a side of the immediately adjacent door panel opposite to the lead edge.
