Parapet Holding Rail with Independent Clamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for balustrades or railings are complex and difficult to manufacture, and they do not allow for simple adjustment of the vertical position of the surface element during assembly, especially when dealing with vibrations or tilting issues.
Innovation Solution
A holding device with screws that directly insert into the holding legs of the rail, allowing for independent adjustment of clamping elements along diagonally arranged support surfaces, enabling precise alignment and tilting of the surface element by adjusting screws, and incorporating restoring elements for easier adjustment and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part wedge module with several positioning wedges is used to adjust the vertical position of the panel plane, then the adjustment capability is improved, but the device complexity increases
Solution Approach 1:
The holding device is divided into two independent holding legs, each with its own clamping element and adjustment screw. This segmentation allows independent adjustment of each side, simplifying the overall structure while maintaining full adjustment capability for vertical position and angular alignment of the surface element.
Solution Approach 2:
The complex multi-part wedge module is replaced by extracting only the essential adjustment function. Each holding leg has a simple clamping element with an adjustment screw that directly interacts with the support surface, eliminating the need for multiple positioning wedges and cradles while achieving the same adjustment objectives.
2Ease of manufacture
If the threaded sections of the screws are screwed into the retaining legs of the retaining rails, then the manufacturing complexity is reduced, but the clamping force may be reduced
Solution Approach 1:
The adjustment screw and clamping mechanism are merged into a single integrated component. The screw passes through the clamping element and engages with the holding leg, combining the adjustment function and clamping function in one element. This reduces the number of parts and simplifies manufacturing while maintaining adequate clamping force through the direct mechanical engagement.
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
The solution provides a compact, easy-to-manufacture holding device that allows for precise adjustment of the surface element's vertical position and angle, preventing tilting and simplifying assembly by allowing for independent adjustment of clamping elements, thus ensuring accurate alignment of multiple elements.
Implementation Method 1
several screws for adjusting the clamping elements relative to the two retaining legs along the vertical axis, the screws extending through through holes formed in the clamping elements
Implementation Method 2
the lower positioning wedges strike against stops on the retaining arms when the cradle's vibration amplitude exceeds +/- 1° relative to the vertical axis, preventing the plate from tilting during installation

AI summary
The invention relates to a holding device for a surface element (2) of a parapet or railing, comprising a holding rail (3) extending along a longitudinal axis (L) and a first holding leg (4), a second holding leg (5), and a connecting web (6) between the two holding legs (4, 5). The two holding legs (4, 5) project from the connecting web (6) on both sides of a vertical axis (H) and define a receiving slot (10) between them for receiving a foot section (11) of the surface element (2). The two holding legs (4, 5) have support surfaces (29) that abut counter surfaces (30, 31) of clamping elements (13, 14). The clamping elements (13, 14) can be adjusted along the vertical axis (H) by means of screws (16). The clamping elements (13, 14) allow the surface element (2) to be clamped on one side and aligned in its vertical position.
