Track-Mounted Sliding Door Lock with Automatic Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding glass doors and windows are vulnerable to unauthorized access due to the need for manual locking and the potential for locks to be easily manipulated, and existing secondary locking devices often require physical attachment to the frame or leave unsightly holes when removed.
Innovation Solution
A secure locking device comprising a main bar and lever bar that can be placed within the sliding door or window track, featuring a lever actuator and lock button for automatic locking when the door or window is closed, allowing easy unlocking by stepping on the lever actuator without the need for permanent attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual lock or latch is used on sliding doors or windows, then the door can be locked in place, but it requires manual activation and can be easily manipulated with tools
Solution Approach 1:
The locking device automatically locks when the sliding door is closed by utilizing the door's own movement to engage the lock mechanism, eliminating the need for manual locking activation. The system serves itself by converting the closing action into a locking action.
Solution Approach 2:
The lock is pre-positioned within the track so that when the door slides closed, the locking mechanism is already in place and automatically engages with the door frame, preventing the need for separate locking actions.
2Reliability
If a secondary lock device is physically mounted to the door frame with bolts, then it provides additional security, but it leaves unsightly holes in the frame when removed
Solution Approach 1:
The locking device is extracted from the category of permanently mounted devices. Instead of being fixed to the frame with bolts, it operates independently within the track, removing the need for physical attachment to the door frame structure.
Solution Approach 2:
The track serves as an intermediary medium that allows the locking device to function without direct attachment to the door frame. The device interacts with the frame through the track system rather than through permanent mounting points.
3Ease of operation
If a telescoping arm device is used for locking, then it allows foot-operated unlocking without bending, but it requires physical mounting to the frame
Solution Approach 1:
The device is extracted from frame-mounted configurations. The locking mechanism operates independently within the track, eliminating the need for complex mounting structures while maintaining foot-operated functionality.

AI summary
A device for placing in a sliding door or sliding window frame that adds additional security to prevent a sliding door or sliding window from being opened. The device is a secure locking device which comprises of a main bar and a lever bar that are connected to each other such that lever bar may pivot where it is connected to the main bar. The main bar is adjustable such that a length may be adjusted to allow the secure locking device to fit within varied sizes of sliding door/window frames. The secure locking device is also comprised of a locking mechanism that is controlled by a lever actuator and a lock button which are configured onto the main bar. The secure locking device is easily accessible by a user to lock and unlock in order to secure and unsecure the sliding door. The secure locking device is easy to position in a track of the sliding panel and does not require any need to secure into place.
