Sliding Door Locking System with Movable Strike Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for sliding carpentry, such as windows and doors, are complex to use and implement, and often increase costs due to the need for additional devices for ventilation and locking mechanisms that are independent of the primary locking system.
Innovation Solution
A locking system for sliding carpentry that integrates a device allowing the locking element to occupy two distinct positions, enabling secure locking in both complete closing and ajar positions without requiring additional complex mechanisms or significant cost increases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a half-opening device is added to the locking system, then ventilation functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines the half-opening device with the locking system by integrating a movable element into the strike plate that can occupy two distinct positions. This merging eliminates the need for separate independent devices while providing both full closing and ventilation functions through a unified mechanism.
Solution Approach 2:
The strike plate is designed with a movable element that serves multiple functions: it provides the primary locking function when in the first position and enables half-opening ventilation when in the second position. This multi-functionality allows a single component to replace what would traditionally require separate devices.
2Adaptability or versatility
If additional devices are added for half-opening functionality, then ventilation capability is improved, but implementation complexity increases
Solution Approach 1:
The half-opening device is merged with the existing locking system components. The movable element is integrated into the strike plate, and the anchoring points are incorporated into the same structure, eliminating the need for separate manufacturing and installation processes for additional devices.
Solution Approach 2:
The strike plate is segmented into a base and a movable element that can independently occupy different positions. This segmentation allows the single component to provide multiple functions (full closing and half-opening) without requiring multiple separate devices to be manufactured and installed.
3Adaptability or versatility
If independent half-opening devices are used, then ventilation function is achieved, but cost increases
Solution Approach 1:
The locking system is designed to perform both primary locking and half-opening ventilation functions through its existing components. The movable element in the strike plate and the multiple anchoring points enable the system to provide multiple functions without requiring additional expensive devices.
Solution Approach 2:
By merging the half-opening functionality into the existing locking system structure, the patent eliminates the need for separate expensive devices. The same components that provide locking also enable ventilation, reducing overall system cost.

AI summary
The invention relates to a locking system (10) for a sliding joinery comprising a frame (2), two sashes (1, 1') of which at least one is movable in translation relative to the frame (2) along a sliding direction between an open position and a fully closed position, the locking system (10) being provided with at least one control means (20), at least one locking element (30) such as a strike plate, at least one locking device (40) such as a locking hook or such as a locking roller and at least one door restrictor device (50) comprising a base (52) fixed to the locking element (30) and a movable element (54) capable of occupying at least two distinct positions.
