Sliding Lock with Integrated Bolt Block for Sash Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for sliding doors face challenges in providing a compact, easy-to-install, and secure solution that effectively prevents movements in the sliding direction, lifting, and passage directions simultaneously, while existing counter-rotating bar combinations are complex and space-intensive.
Innovation Solution
A lock system featuring a combined actuating element and bolt lock within a sliding locking slide, with mirror-symmetric hook-shaped lock bolts that pivot and engage in a recess, allowing for a compact design with robust blocking capabilities and improved mountability, utilizing an inclined guide slot and holding magnets for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opposing bolt combinations are used to prevent lifting and sliding movements, then security is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple locking functions into a single integrated locking slide that houses both the actuating element and the bolt lock. This merging of components into one unified structure reduces the overall number of parts, simplifies installation, and decreases space requirements while maintaining the security benefits of opposing bolts
2Reliability
If opposing bolt combinations are used to prevent lifting and sliding movements, then security is improved, but device complexity and space requirements increase
Solution Approach 1:
The actuating element and bolt lock are nested within the locking slide structure. The actuating element is positioned inside the locking slide, and the bolt lock features are integrated into the same component, creating a compact nested arrangement that reduces the overall volume required for the locking mechanism
3Ease of operation
If simple hook bolts are used, then ease of installation is improved, but reliability deteriorates due to easy lifting
Solution Approach 1:
The patent merges the actuating mechanism and the bolt lock into a single integrated locking slide component. This combination maintains the simplicity of installation while adding the security feature of the bolt lock that prevents lifting, which simple hook bolts alone cannot provide
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 enables a compact, easy-to-install, and secure locking mechanism that effectively blocks pivoting and sliding movements, achieving high security classification with reduced complexity and space requirements.
Implementation Method 1
the lock has at least one holding magnet which, in the enclosed open position, retains the locking slide
Implementation Method 2
The actuating element has an inclined guide slot which interacts with a pin on each lock bolt

AI summary
The invention relates to a lock (1) for a sash, in particular a sliding sash, with a lock case (3) which is closed on one side by a faceplate (5), and a locking arrangement (10) arranged in the lock case (3), which has an opposing bolt combination with a hook-shaped first lock bolt (12A) and a hook-shaped second lock bolt (12B), which are pivotably arranged relative to each other and can be moved through an opening (5.1) in the faceplate (5) between an enclosed open position and a locked position excluded from the lock case (3), in which the lock bolts (12A, 12B) each engage in a recess (7).1) engage in a strike plate (7), wherein an actuating element (20A) upon corresponding actuation moves the opposing lock bolts (12A, 12B) from the enclosed open position to the excluded locking position or from the excluded locking position to the enclosed open position, and wherein a bolt lock (20B) blocks the pivoting movement of the lock bolts (12A, 12B) in the excluded locking position and releases it in the enclosed open position, and a system with at least one sliding leaf which has such a lock.According to the invention, the actuating element (20A) and the bolt lock (20B) are combined in a slidingly mounted locking slide (20), which is displaceable between a release position in the enclosed open position and a locking position in the excluded locking position, wherein the locking slide (20) blocks the lock bolts (12A, 12B) in the locking position.
