Sliding Sash Securing Device with Elastic Grippers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for securing sliding leaves in sliding sash systems are difficult to access and remove, making assembly and disassembly complicated, especially when removing a side wing.
Innovation Solution
A device with elastically designed grippers that attach to the sliding head of a floor rail, featuring a detachable hold-down mechanism with guide grooves and a latching element, allowing easy installation and removal, and integrating a roller mount for combined securing and roller carriage functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spacer elements are used in the ceiling rail to secure sliding leaves, then the sliding leaf can be secured against vertical movement, but the securing device becomes difficult to access and remove
Solution Approach 1:
The securing device is divided into separate components: a hold-down device with grippers that can be independently inserted into the ceiling rail, and a housing that attaches to the sliding leaf. This segmentation allows the hold-down device to be accessed and removed separately from the sliding leaf assembly, solving the accessibility problem while maintaining the securing function.
Solution Approach 2:
The hold-down device acts as an intermediary component between the ceiling rail and the sliding leaf. It can be inserted into the ceiling rail through accessible openings and engages with the rail's internal structure, providing securing without requiring direct access to deep internal components of the ceiling rail assembly.
2Adaptability or versatility
If multiple separate components are used for securing and roller carriage functions, then each function can be optimized independently, but the device complexity and number of components increases
Solution Approach 1:
The housing is designed to combine multiple functions: it attaches to the sliding leaf, provides mounting for the roller carriage, and incorporates the hold-down device for securing. By merging these functions into a single integrated housing component, the design reduces the total number of parts while maintaining the ability to optimize each function independently through modular sub-components.
Solution Approach 2:
The housing serves multiple purposes simultaneously: structural support, roller carriage mounting, and hold-down device housing. This multi-functionality reduces component count while allowing each functional element to be independently designed and optimized for its specific purpose.
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 device provides easy access and removal while securing the sliding sash, reducing component count and simplifying the assembly process, and is cost-effectively manufactured using plastic for mass production.
Implementation Method 1
The at least one locking element is connected to the hold-down device via a spring arm
Implementation Method 2
the two elastically designed grippers, which grip behind the sliding head of the catwalk of a floor rail

AI summary
The apparatus has a housing that is fastened to sliding leaf, to which blank holder (7) is detachably connected. A web (19) is formed between side walls, on which an undercut (191) is formed. A guide groove (73) is introduced into blank holder n its longitudinal sides, such that folding arm (18) is pushed. A spring arm (74) having an outwardly directed detent element (741) is located in pushed state. The spring arm is biased against the web, such that spring arm is engaged into undercut of web. The sliding leaf is guided on one slide head of running web of floor rail. The holder is provided with oppositely arranged elastically formed gripper (71) for engaging behind the slide head of running web. The folding arm with guide web (181) is formed on opposite side walls of housing, which are connected through cover plate.
