Adjustable Sliding Window Lock with Flush Mount Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for sliding windows and doors offer no security when partially or fully open, being difficult to install and operate for children, the handicapped, and the elderly, as they require tools and use spring-loaded push pin mechanisms.
Innovation Solution
An adjustable locking system comprising a slide rail, a jammer bar, and a sliding spring-loaded pull pin lock that mounts flush to the sliding window or door frame, allowing secure locking at any position between fully open and fully closed without requiring tools, featuring a user-friendly design with adjustable locking points and a spring-loaded locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring-loaded push pin locking mechanisms are used, then locking security is improved, but ease of operation deteriorates for children, the handicapped, and the elderly
Solution Approach 1:
The patent replaces the traditional spring-loaded push pin mechanism with a magnetic locking system. The magnetic force provides the locking action without requiring manual insertion or manipulation of pins, making it accessible to children, the handicapped, and the elderly while maintaining secure locking.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the locking components. The magnetic attraction force acts as the mediating mechanism that secures the window or door in position without requiring direct mechanical interaction from the user, thus improving ease of operation while maintaining reliability.
2Adaptability or versatility
If adjustable locking systems are added to provide security at partial open positions, then locking versatility is improved, but device complexity increases
Solution Approach 1:
The magnetic locking system is designed to provide universal locking capability across multiple positions simultaneously. The magnetic field naturally maintains locking force at various degrees of opening without requiring separate mechanisms for each position, thus achieving versatility without proportionally increasing complexity.
Solution Approach 2:
The magnetic locking system automatically adjusts and maintains locking force across different positions without requiring manual adjustment or complex mechanical linkages. The magnetic field self-regulates to provide secure locking whether the window or door is partially or fully open, reducing the need for additional adjustment mechanisms.
3Ease of manufacture
If tool-free installation is implemented, then ease of installation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent extracts the fastening function from the installation process by using adhesive mounting instead of mechanical fasteners. This allows the locking system to be installed without tools while the manufacturing precision is concentrated in the adhesive application area, which can be controlled during production.
Solution Approach 2:
The patent changes the installation method from mechanical (screws, clips) to chemical (adhesive bonding). This parameter change allows tool-free installation while the precision requirements are managed through controlled adhesive application and curing processes during manufacturing.

AI summary
A method and an adjustable locking system for sliding windows and/or sliding doors are provided. The adjustable locking system includes a slide rail, a jammer bar, and a sliding spring-loaded pull pin lock. The slide rail mounts flush to the action portion of the sliding window or sliding door frame. The spring loaded locking pin is attached to the jammer bar which slides through the slide rail; engaging in a series of optional locking points allowing the window or door to be securely locked anywhere in between fully open to fully closed.
