Sanitary Mounting Frame Fastening Set With Tool-Free Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening sets for sanitary objects have limited adjustment range and require tools to release the lock, making them inefficient for flexible mounting solutions.
Innovation Solution
A fastening set with a channel-shaped connecting part and a slider that allows axial displacement from a non-contact to a contact position, featuring radial shoulders and a groove-shaped thread base for secure engagement, enabling a large adjustment range with compact dimensions and tool-free locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fastening set with a plug-in part and internal thread is used, then quick assembly is guaranteed, but the maximum adjustment range is limited and the lock cannot be released without tools
Solution Approach 1:
The slide is designed to be movable along the connecting rod, transitioning between a first position (locking engagement) and a second position (disengagement). This dynamic positioning allows the fastening set to adapt between locked and unlocked states without requiring tools, resolving the contradiction between ease of operation and adjustment range.
Solution Approach 2:
The fastening set is divided into distinct functional components: the slide, the connecting rod with external thread, and the channel-shaped connecting part with internal thread. This segmentation allows independent movement of the slide along the connecting rod, enabling tool-free adjustment and release while maintaining secure locking when engaged.
2Productivity
If a U-shaped clip nut is used for detachable connection, then quick assembly with rough adjustment is enabled, but the maximum adjustment range remains limited
Solution Approach 1:
The slide can dynamically transition between multiple positions along the connecting rod's longitudinal axis. In the first position, it engages with the internal thread for secure locking. In the second position, it disengages to allow free movement for rough adjustment. This dynamic capability enables both quick assembly and extended adjustment range without compromising productivity.
3Reliability
If a locking hook-shaped latching element is used, then the connection is secured against loosening, but the contact position can be exceeded only awkwardly by bending the locking element
Solution Approach 1:
The slide provides a controlled dynamic mechanism for engaging and disengaging the locking position. By moving the slide along the connecting rod between the first and second positions, the system achieves reliable locking when engaged while allowing easy, tool-free reverse displacement by simply moving the slide, eliminating the need to bend the locking element.

AI summary
The invention relates to a fastening set (1) for fastening a mounting frame for sanitary objects, in particular for a cistern, a toilet bowl and/or a washbasin, to a building wall, with a connecting rod (4) which can be fastened to the mounting frame, and with a fastening part (3) attached to one end of the connecting rod (4) and which can be fastened to a building wall, the connecting rod (4) having at least one longitudinal section having an external thread (4.1). So that such a fastening set offers a relatively large adjustment range as a quick fastening set with compact, space-saving dimensions, the connecting rod (4) is provided according to the invention with a channel-shaped connecting part (5) which can be detachably connected to the assembly frame and in which the connecting rod (4) is guided in an axially displaceable manner , wherein the channel-shaped connecting part (5) is provided with a slider (6) which is slidable on the connecting part (5) axially to the longitudinal axis of the connecting rod (4) from a non-contact position to a contact position and vice versa, and wherein the slider ( 6) has a contact section (6.1) facing the connecting rod (4) which in the contact position bears against the external thread (4.1) of the connecting rod (4).
