Bracket Support Device with Gravity-Fold Pivot for Scaffolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket support devices for scaffolding are time-consuming to assemble and disassemble, often requiring additional screws and occupying valuable space, especially when thermal insulation is applied to old buildings, which increases the distance between scaffolding and the wall, limiting workspace for craftsmen.
Innovation Solution
A bracket support device with a projection unit and pivot bolt that allows for easy lateral insertion into the upright tube, enabling the device to fold automatically into a perpendicular position without additional assembly measures, and featuring a form-fitting unit for secure fixation, allowing quick assembly and disassembly without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bracket support devices are used with welded half-couplings and bolts, then secure connection is achieved, but assembly and disassembly become very time-consuming
Solution Approach 1:
The connection structure is divided into separate functional elements: a connecting structure with axis of rotation that detachably connects to the upright tube, and a form-fitting unit that provides additional fixation. This segmentation allows the device to be assembled and disassembled in simple steps without complex fastening operations, resolving the contradiction between secure connection and quick assembly.
Solution Approach 2:
The connecting structure incorporates an axis of rotation that runs essentially perpendicularly to the longitudinal direction of the support profile, enabling the bracket to be rotatably connected to the upright tube. This dynamic connection allows for easy attachment and detachment while maintaining secure connection during use, directly addressing the time-consuming assembly issue.
2Adaptability or versatility
If additional scaffolding anchor connections are made below the gusset plate, then connection points are available, but headroom and workspace are reduced
Solution Approach 1:
The connecting structure is designed to attach to the upright tube at a position that utilizes the vertical dimension above the gusset plate. By moving the connection point upward along the upright tube, the invention provides adaptable connection availability without encroaching on the horizontal workspace and headroom below the gusset plate.
3Reliability
If the bracket support device is designed with complex connection structures, then secure attachment is ensured, but device complexity increases
Solution Approach 1:
The invention merges the connecting structure with the form-fitting unit into an integrated assembly. The connecting structure with its axis of rotation and the form-fitting unit work together as a unified system, reducing the number of separate components and simplifying the overall device while maintaining secure attachment reliability.
Solution Approach 2:
The form-fitting unit is designed to automatically provide form-fitting fixation in the connected state through its geometric shape, without requiring additional fastening operations or complex adjustment mechanisms. This self-service feature simplifies the connection structure while ensuring reliable attachment.

AI summary
The device (10) has a connection construction unit exhibiting a rotation axis that runs perpendicular to a longitudinal direction of a u-shaped supporting profile. The device is brought in a position running perpendicular to a longitudinal axis of a stand tube (30) under the effect of gravitation in a condition, in which the stand tube is attached in a detachable manner. A form fit unit is provided at the profile such that form-fit fixation of the profile at the stand tube is produced transverse to the longitudinal direction of the profile, in an attached condition.
