Profiled Rail Holder With Pivot Clamp for Stable Fast Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for profiled rails are complex to manufacture and install, prone to displacement during screw tightening, and require separate provision and pre-insertion of nuts, complicating the installation process.
Innovation Solution
A holder design featuring a base body with a supporting surface, a clamping element, and a screw connection, incorporating a rotary joint with an axis of rotation parallel to the supporting surface, allowing the clamping element to pivot between open and closed positions, and a screw connection that can be fixed to a carrier component, eliminating the need for separate nut provision and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the holder uses a separate nut that must be pre-inserted into the carrier component, then the screw connection can be established, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent integrates the nut directly into the holder body as an integral component rather than providing it separately. This merging of components eliminates the need for separate nut insertion steps, simplifying the installation process while maintaining the screw connection functionality. The holder body now contains both the mounting features and the nut structure as a unified component.
Solution Approach 2:
The holder body serves multiple functions: it provides structural support, contains the nut for screw connection, and enables both screw-driven and tool-free installation modes. This multi-functionality reduces the need for separate components and simplifies the overall assembly process.
2Strength
If the screw connection is tightened to firmly clamp the profiled rail, then the clamping force increases, but the base body may be displaced from its original installation position
Solution Approach 1:
The holder is first positioned on the carrier component before the screw connection is tightened. The preliminary positioning features ensure the holder is correctly located, and then the screw connection is actuated to clamp the profiled rail without causing displacement of the holder itself, as the positioning already occurred before tightening.
Solution Approach 2:
The holder design separates the positioning function from the clamping function. The base body handles positioning on the carrier component, while the clamping element handles securing the profiled rail. This segmentation allows the clamping action to occur without affecting the installation position stability.
3Adaptability or versatility
If the holder design includes a rotary joint for radial guidance of the clamping element, then the clamping mechanism becomes more adaptable, but the manufacturing complexity increases
Solution Approach 1:
The rotary joint enables dynamic movement of the clamping element between radial and axial positions, allowing adaptation to different installation scenarios. This dynamic capability provides versatility in how the clamping element can approach and secure the profiled rail while maintaining manufacturability through a relatively simple rotational mechanism.

AI summary
A holder for a profiled rail comprising a holding edge and a for carrier component includes a base body, a clamping element, a screw connection, and a rotary joint. The base body comprises a supporting surface configured to have the profiled rail be placed thereon, a holding-down strip which holds down the holding edge against the supporting surface, and a first opening. The clamping element comprises a second opening. The screw connection passes through the first and second opening and is fixable on the carrier component. The rotary joint comprises an axis of rotation arranged parallel to the supporting surface and to the holding-down strip. The clamping element clamps the profiled rail against the base body with the screw connection. On the base body, the clamping element is guided radially with respect to the axis of rotation between an open and a closed pivot position with the rotary joint.
