Glass Balustrade Holding Device with Adjustable Box Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for glass balustrades are expensive to produce due to their structurally complex design, which is not necessary for all applications, leading to high production costs.
Innovation Solution
A holding device where the adjusting screw is supported in a box rail connected to a retaining plate via a support element, eliminating the need for complex moldings and allowing for adjustable support rail positioning, with clamping screws to absorb horizontal forces and their torques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base profile is designed with complex moldings to support adjusting screws for inclination adjustment, then the support rail can be adjusted to various inclinations, but the production cost increases significantly
Solution Approach 1:
The base profile is divided into two separate components: a simple base profile and a separate support element (box rail). The adjusting screw is mounted on the support element, not the base profile. This segmentation allows the base profile to be manufactured simply while the support element provides the adjustment functionality, resolving the contradiction between adjustability and manufacturing complexity.
Solution Approach 2:
A support element (box rail) is introduced as an intermediary component between the base profile and the adjusting screw. This mediator carries the adjusting screw and transfers forces between the support rail and base profile, allowing the base profile to remain simple while still enabling inclination adjustment through the intermediary support element.
2Reliability
If the base profile provides a continuous bearing surface over the entire length of the railing, then the support rail is stable, but the structural complexity and production cost increase
Solution Approach 1:
The support function is segmented between the simple base profile (attached to wall/ceiling) and the separate support element (box rail). The base profile provides anchoring while the support element provides the bearing surface and adjustment mechanism, reducing overall structural complexity while maintaining stability.
Solution Approach 2:
Instead of requiring the base profile to provide all support functions along its entire length, the invention uses discrete support elements (box rails) at specific locations. This partial action approach provides sufficient stability without the excessive complexity of a continuously complex base profile structure.
3Device complexity
If the adjusting screw is directly integrated into the base profile, then the structure is compact, but the base profile requires complex moldings that increase production cost
Solution Approach 1:
The adjusting mechanism is segmented from the base profile and placed on a separate support element. This allows the base profile to remain structurally simple while the support element with the adjusting screw provides the required adjustment functionality, resolving the contradiction between structural simplicity and operational capability.

Function Achieved in This Case
This design simplifies the production of the retaining plate, reduces costs, and provides reliable support for the railing while allowing for adjustable inclination and adaptation to various structural conditions.
Implementation Method 1
a large number of adjusting screws are provided, which are screwed into a threaded hole which is incorporated in the fixed bearing of the base profile
Implementation Method 2
a clamping screw is provided on the side next to each adjusting screw, which is screwed into the box rail and a nut frictionally held in it and which rests on the outside of the support rail

AI summary
The device (1) has a mounting rail (7) placed on a support element (12) in an assembly condition in a vertical direction. Set screws (16) and clamping screws protruded from a box rail (11) in a direction of the mounting rail. The set and clamping screws are force-fittingly and/or form-fittingly connected with the mounting rail. Distance between the box and mounting rails is variably adjustable by the set screws. The support element is formed as a planar strip and a box-shaped rail (14), and welded or screwed completely or in sections at a holding plate (9).
