Espag Bolt Lock With Retrofit Motor And Latch Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing espagnolette locks require a continuous power supply and lack versatility in operation, with limited functionality and adaptability to different applications.
Innovation Solution
A deadbolt lock design with a modular lock housing that allows for retrofitting with a motor module, latch ejector, or door opener, enabling both manual and motorized operation, and adaptable to various backset sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a motorized drive is always required for espagnolette lock, then motorized unlocking is achieved, but power supply is always needed and manual operation is lost
Solution Approach 1:
The lock system dynamically adapts between manual and motorized operation modes. The motor module can be installed or omitted based on application requirements, allowing the same lock housing to serve different operational needs. The bolt slide and latch ejector remain mechanically functional regardless of motor presence, enabling manual operation when motorized mode is not required.
2Reliability
If lock housing is designed for specific backset, then secure locking is achieved, but adaptability to different backsets is limited
Solution Approach 1:
The lock system is segmented into modular components: a standardized lock housing containing the bolt slide, latch ejector, and mounting mechanism, separate from the espagnolette bars. This segmentation allows the housing to maintain consistent dimensions for secure installation while the espagnolette bars can be adjusted or selected to accommodate different backset requirements.
3Adaptability or versatility
If multiple components are always included, then full functionality is achieved, but manufacturing cost increases
Solution Approach 1:
The lock housing is designed as a universal platform that can accommodate different configurations. The same housing can be manufactured with or without the motor module, and can include or exclude the latch ejector depending on the specific application. This multi-functionality approach allows standardized manufacturing of the base housing while enabling cost-effective customization through optional modules.

AI summary
The invention relates to a drive bolt lock (2) for locking and unlocking a fixed leaf (14) of a double-leaf door (11), having a lock housing (21) in which a retractable slide (241) for a drive bolt rod (24) and a bolt slide (5) are accommodated, and a slide plate (27) is mounted so as to be linearly displaceable and a lock nut (23) with a nut lever (231) is mounted so as to be rotatable in order to manually unlock the drive bolt lock (2). In order to enable a broad applicability of the espagnolette lock (2), it is provided that the lock housing (21) has at least two installation spaces (81, 82, 83, 84, 85), wherein a motor module for motor-driven unlocking of the espagnolette lock can be installed or retrofitted in a first installation space (81), and a latch slide module (4) can be installed or retrofitted in a second installation space (82).
