Window Handle Socket with Spring-Loaded Locking Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual actuating systems for windows and doors often require a rosette or enlarged elements that protrude outward, limiting space and complicating the attachment of driver elements.
Innovation Solution
A handle system with a gear nut that features a recess with a spring-loaded locking or clamping element, allowing for secure attachment of a driver element without the need for a rosette, and incorporating a rest function for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rosette or enlarged elements are used for attaching driver elements, then the attachment security is improved, but the installation space is reduced and the design becomes more complex
Solution Approach 1:
The locking element is nested within the gear nut, with the locking element being received inside the gear nut body rather than protruding outward. This allows the attachment mechanism to be contained within the existing gear nut footprint, maintaining compact installation space while providing secure attachment of the driver element through the internal locking mechanism
Solution Approach 2:
The attachment function for the driver element is merged with the gear nut itself by integrating the locking element and recess features directly into the gear nut structure. This eliminates the need for separate external attaching means and allows the gear nut to simultaneously serve as both the drive transmission component and the secure mounting point for the driver element
2Reliability
If a rosette or enlarged elements are used for attaching driver elements, then the attachment security is improved, but the device complexity increases
Solution Approach 1:
The attachment function for the driver element is merged with the gear nut itself by integrating the locking element and recess features directly into the gear nut structure. This eliminates the need for separate external attaching means and allows the gear nut to simultaneously serve as both the drive transmission component and the secure mounting point for the driver element
Solution Approach 2:
The gear nut is designed with multi-functionality, serving simultaneously as the drive transmission element (engaging with the window mechanism), the mounting structure for the driver element (through the integrated locking element), and the compact housing for the attachment mechanism. This universal design provides secure attachment without requiring additional specialized components
3Ease of operation
If a spring-loaded locking element is used, then the quick-release fastening is improved, but the device complexity increases
Solution Approach 1:
The spring-loaded locking element provides self-service functionality by automatically engaging with the driver element when inserted and requiring only simple manual actuation for release. The spring mechanism automatically maintains the locked state during normal operation and enables quick release when needed, without requiring complex control systems or multiple操作步骤
Solution Approach 2:
The locking element incorporates a dynamic spring mechanism that allows it to flexibly engage and disengage from the driver element. The spring provides the necessary force for automatic engagement while allowing controlled release, creating a dynamic attachment system that is both secure during operation and easily releasable when needed

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 system enables a comfortable and quick attachment of the driver element, providing a secure connection while maintaining a compact design without the need for external connecting means or restricants, and allows for a rest function to achieve precise rotary positions.
Implementation Method 1
The clamping frame is spring-loaded by a single compression spring

AI summary
The invention relates to an actuating handle for components such as windows, doors and the like, comprising at least one driver element, which can be brought into engagement with a handgrip for conjoint rotation, and a socket for integration in a window or door mechanism. The invention is characterised in that the socket has a recess extending through an axis of rotation of the socket with at least one spring-loaded blocking or clamping element pivotably mounted therein, which can be brought into force-fitting, form-fitting and/or frictional engagement with the driver, and in that the socket has on its outer periphery radially inwardly directed latching recesses to receive latching elements.
