L-Shaped Guide Slider With Deformable Fastening Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide sliders for lifting/sliding doors, especially those attached to steel-free profile frames, face stability issues under heavy use and require complex assembly with additional inserts, which increase costs and manufacturing difficulties.
Innovation Solution
A guide slider with a rectangular L-shaped design featuring a guide pin and a deformable fastening pin that interacts with a guide profile and profile frame, allowing secure attachment without additional inserts, using a fastening means like screws to deform and expand the fastening pin for a stable and form-fitting connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional inserts are used to improve screw connection stability in steel-free profile frames, then the stability and reliability of the guide slider attachment is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The invention extracts the fastening function from a separate insert component and integrates it directly into the guide slider body through the fastening pin. This eliminates the need for additional inserts while maintaining the stability of the attachment to steel-free profile frames.
Solution Approach 2:
The guide slider body and fastening mechanism are merged into a single integrated component. The fastening pin is directly formed as part of the guide slider, combining the guiding function and the fastening function into one element, thereby simplifying the overall device structure.
2Strength
If additional inserts are introduced into corner areas of the casement, then the screw connection stability is improved, but the manufacturing difficulty and costs increase
Solution Approach 1:
The invention removes the need for separate inserts by extracting the fastening function and integrating it into the guide slider itself. The fastening pin is directly formed as part of the guide slider body, eliminating additional manufacturing steps for inserting and securing separate insert components.
Solution Approach 2:
The guide slider is designed to be self-fastening through its integrated fastening pin that deforms upon insertion to create a secure connection. The component serves its own fastening function without requiring additional inserts or complex assembly procedures.
3Reliability
If a deformable fastening pin is used to create form-fitting connection, then the attachment stability under heavy use is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The invention utilizes parameter changes in the fastening pin's physical state during installation. The pin is inserted in a deformable state and then deforms elastically to create a form-fitting connection. The material properties and geometric parameters are designed to enable controlled deformation that ensures reliable attachment.
Solution Approach 2:
The fastening pin is designed with inherent elastic properties that provide cushioning during the deformation process. This elastic cushioning allows the pin to absorb installation variations and maintain a stable connection without requiring extremely tight manufacturing tolerances.

Function Achieved in This Case
The solution provides enhanced stability and secure attachment to steel-free profile frames without the need for additional inserts, ensuring the guide slider remains stable under heavy use and simplifies the attachment process, reducing costs and manufacturing complexity.
Implementation Method 1
a fastening means, preferably a screw, can be introduced through the opening in order to mechanically interact with the fastening pin and to fasten the guide slider to the positively and / or non-positively deform sash frame
Implementation Method 2
The fastening pin (6) is designed in such a way that it can be deformed by means of the fastening means (25)
Implementation Method 3
a guide pin which is arranged on an outer side of the first leg, preferably in the center, and which extends transversely to the first leg

AI summary
The guide slider (1) has a first leg (2) whose inner surface forms right angle with an inner surface of the second leg (3). A guide pin (10) is centered on an outer side of the first leg. A mounting pin (6) is placed on the inside of the first leg and extended transversely to an opening (14) in second leg. An aperture is arranged and configured such that a fastener (25) such as countersunk head screw is inserted through the aperture to cooperate mechanically with fixing pin and to deform the pin on positive and/or frictional fastening of the guide slider on the casement (18). An independent claim is included for a method for fastening the functional element.
