Door Lock with Extracted Receptacle for Thin Leaf Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window locks require significant work to install, are limited by the thickness of the leaf, and have ergonomic issues, particularly requiring auxiliary gripping members and complex emergency opening mechanisms.
Innovation Solution
A lock design that includes a lock body with a magnetic retaining device, a bar with a polygonal cross-section for actuating the bolt, and ergonomic handles that can be telescopically coupled to fit various leaf thicknesses, including those as thin as 14 millimeters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional locks with recessed receptacles are used, then the lock can be actuated from both sides, but the leaf requires significant thickness and complex installation work
Solution Approach 1:
The invention extracts the receptacle from the leaf structure and relocates it to the frame structure. The receptacle is now formed in the frame rather than requiring a recessed seat in the leaf, eliminating the need for complex leaf machining while maintaining bidirectional actuation capability
Solution Approach 2:
The invention introduces a bridge element that connects the handle to the bolt through the frame structure. This intermediary mechanism allows the handle to actuate the bolt from either side of the leaf without requiring the handle to directly contact the bolt, thereby eliminating the need for recessed receptacles in the leaf
2Ease of operation
If traditional locks with recessed receptacles are used, then the lock can be actuated from both sides, but the installation time and work required increases
Solution Approach 1:
The invention extracts the receptacle from the leaf structure and relocates it to the frame structure. The receptacle is now formed in the frame rather than requiring a recessed seat in the leaf, eliminating the need for complex leaf machining while maintaining bidirectional actuation capability
Solution Approach 2:
The receptacle is pre-formed in the frame during frame manufacturing, eliminating the need for time-consuming on-site leaf machining. The bridge element and handle assembly can be directly installed onto the pre-prepared frame structure, significantly reducing installation time
3Length of moving object
If the leaf thickness is reduced, then the aesthetic appearance and material usage improve, but the traditional lock cannot be installed
Solution Approach 1:
The invention extracts the receptacle from the leaf structure and relocates it to the frame structure. The receptacle is now formed in the frame rather than requiring a recessed seat in the leaf, eliminating the need for complex leaf machining while maintaining bidirectional actuation capability
Solution Approach 2:
The invention shifts the lock mechanism from a leaf-mounted configuration to a frame-mounted configuration. By moving the receptacle and bridge element to the frame, the lock can accommodate thin leaves without requiring thickness for recessed seats, effectively utilizing the frame dimension instead
4Ease of operation
If auxiliary gripping members are added for ergonomic handles, then the handle becomes easier to grip, but the device complexity and cost increase
Solution Approach 1:
The bridge element serves multiple functions: it acts as a structural connector between the handle and bolt, provides a mounting surface for the receptacle, and creates an ergonomic gripping surface. This multi-functional design eliminates the need for separate auxiliary gripping members while maintaining ease of operation
Applied Scientific Principles
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 solution allows for rapid and easy installation on leaves with reduced thickness, enhances ergonomics with intuitive handle design, and simplifies emergency opening, while maintaining aesthetic appeal.
Implementation Method 1
a lock body (2) connectable to a leaf (A) of a door or a window, the lock body (2) comprising a bolt (4) reversibly movable between a retracted position, in which it is at least partly housed inside the lock body (2), and an extracted position, in which it is at least partly projecting from the lock body (2) so as to define a condition of closure of the door or the window

AI summary
A lock (1) for a door or a window comprising a lock body (2) and an actuating means (6) for moving a locking element (3). The lock (1) further comprises a fixed handle (7) and a rotating handle (8) coupled to the actuating means (6) and rotatable relative to the lock body (2) in order to move the locking element (3) between an extracted position and a retracted position. In particular, the lock (1) comprises a first and a second support element (9, 10), each having a main longitudinal dimension of extension such that they take on a configuration, during use, projecting from a leaf (A). Furthermore, the fixed handle (7) and the rotating handle (8) can be fitted over the first support element (9) and the second support element (10), respectively.
