Adjustable Hanger Bracket for Overhead Door Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanger brackets for overhead sliding doors are time-consuming to install and do not provide sufficient structural support for long-term use, leading to misalignment of guide track rails and openers.
Innovation Solution
A hanger bracket design featuring a first part with an upper wall and spaced side walls for attachment to the building superstructure, and a second adjustable part with a support member and leg for secure attachment to the guide track rail or opener, utilizing slidably engaged and locked mechanisms for easy alignment and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional three-piece angled perforated metal hanger brackets are used, then the door can be installed, but installation is time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple separate metal pieces into a single integrated hanger bracket assembly. The bracket includes a main body with integrated mounting flanges, support arms, and alignment features all formed as one piece, eliminating the need to assemble multiple separate components during installation. This merging of parts directly reduces installation time and labor requirements.
2Reliability
If conventional hanger brackets are used, then installation is simpler, but they do not provide sufficient structural support for long-term use
Solution Approach 1:
The hanger bracket is designed with distinct functional segments: a main body portion for mounting to the structure, support arms extending outward, integrated alignment features, and mounting flanges with pre-drilled holes. Each segment serves a specific structural function, allowing the bracket to provide reliable long-term support while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
The bracket utilizes composite construction combining multiple metal components welded or mechanically joined into a unified structure. The assembly includes steel plates, angle irons, and reinforcement elements that work together to provide enhanced structural strength and durability compared to single-material brackets, ensuring reliable long-term support.
3Stability of the object's composition
If conventional hanger brackets are used, then fewer components are needed, but they do not maintain alignment of guide track rails and openers over time
Solution Approach 1:
The bracket incorporates pre-formed alignment features including built-in alignment pins, pre-drilled alignment holes, and integrated level indicators that are manufactured into the bracket during production. These preliminary alignment features eliminate the need for field adjustments and ensure consistent proper alignment of guide track rails and openers throughout the product's service life.

AI summary
A hanger bracket is used to support at least one of a guide track rail and an opener associated with the overhead sliding door installation for a building from a superstructure of the building. The hanger includes a first part having an upper wall configured to be attached to the superstructure of the building, and a pair of spaced apart side walls depending from the upper wall and defining an open bottom. A second part is adjustable relative to the first part, and has a support member joined to a support leg depending therefrom and configured to be attached to at least one of the guide track rail and the opener. The support member is slidably supported, received and retained on the first part. The side walls are formed with guiding and supporting structure configured to slidably engage the support member thereon.
