AI Technical Summary

Technical Problem

Existing polygonal pin arrangements for door and window handles require a large amount of installation space and complex manufacturing, compromising functional reliability and ease of use.

Method used

A compact polygonal pin arrangement design with radially outwardly projecting coupling structures and a driver mechanism that allows for a small axial installation space, featuring a driver and coupling structures that engage in a rotationally fixed manner, enabling easy actuation and decoupling without additional space requirements.

Benefits of technology

The design achieves a compact, reliable, and easy-to-use handle mechanism with a privacy or safety function, requiring minimal installation space and ensuring precise alignment and operation.

Abstract

The invention relates to a polygonal pin arrangement (8) for a handle set for opening and closing a door or window, comprising a first outer pin (14.1), a second outer pin (14.2) and an inner pin (15) which extends coaxially through one of the two outer pins (14) and is rotatable therein about a pivot axis (12) and is axially adjustable between a coupling position (KS), in which the two outer pins (14) are rotationally fixedly coupled to each other, and a decoupling position (ES), in which the two outer pins (14) are rotatable relative to each other. A compact design is achieved by the first outer pin (14.1) having a radially outwardly projecting first coupling structure (18), the second outer pin (14.2) having a radially outwardly projecting second coupling structure (19), and the inner pin (15) having a radially outwardly projecting driver (20) which, in the coupling position (KS), engages axially with the first coupling structure (18) and with the second coupling structure (19), such that the driver (20) couples the first coupling structure (18) with the second coupling structure (19) in a rotationally fixed manner, and which, in the decoupling position (ES), does not engage axially with the first coupling structure (18), such that the first coupling structure (18) and the second coupling structure (19) are rotatable relative to each other about the axis of rotation (12).
