Solution Overview

Problem

Existing window and door moving devices require additional components like attachment bases or rosettes, increasing production costs and complexity in assembly and mounting, and are not suitable for profiles with reduced sections.

Innovation Solution

A moving device that integrates a supporting and holding body with a rotating element and axial locking mechanism, allowing direct mounting of the handle without additional components, and features a transformation mechanism to convert rotational motion into translational motion for maneuvering or closing members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If attachment bases or rosettes are used to mount handles on the moving device, then the handle can be securely mounted, but the production cost increases and assembly complexity increases

Engineering Contradiction:

Improvesecure mounting of handleVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the attachment base functionality directly into the moving device housing. The housing includes integrated mounting features (such as threaded holes or clip mechanisms) that directly secure the handle, eliminating the need for separate attachment bases or rosettes. This integration reduces the number of components and simplifies assembly while maintaining secure handle mounting.

AI summary

The invention is directed to a moving device for moving manoeuvring or closing members of a window or door of the type controlled by rotation of the pin of a control handle. Said moving device comprises i.a. a rotating element which is housed in a supporting and holding body. The rotating element comprises a hollow seat coaxial with the axis of rotation of the rotating element. The hollow seat comprises a first and a second axial section. The first axial section is shaped to be coupled with a corresponding section of a pin of a control handle. The second axial section is distinct from the first axial section. Furthermore, the rotating element comprises locking means which are arranged in the second axial section for removably locking the axial sliding of the pin, wherein the axial sliding of the pin into the hollow seat is allowed in the direction of insertion and prevented in the opposite direction.
