Sliding Door Electric Strike With Translating Keeper Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric strikes for sliding doors require significant modifications to the door frame cut-out, increasing installation time and cost, and do not support controlled access through key fobs, key cards, or key pads.
Innovation Solution
An electric strike with a strike housing, actuating mechanism, keeper, and blocking member that allows the sliding door to be released from the door frame without modifying the cut-out pocket, using a plunger and keeper system that translates and rotates to unlatch the door latch upon authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a prior art electric strike with a rotatable keeper is used, then the door can be released electrically, but the cut-out pocket in the door frame must be significantly enlarged requiring extensive modifications
Solution Approach 1:
The keeper is designed to perform both rotational and translational movements within the strike cavity, dynamically adjusting its position between engaged and disengaged states without requiring a larger cut-out pocket. This dynamic movement allows the keeper to clear the door latch edge during translation while maintaining compact dimensions
Solution Approach 2:
The keeper's movement is extended from simple rotation in one dimension to a combined rotation and translation path in multiple dimensions. The keeper translates along the door latch edge while rotating, utilizing three-dimensional space within the existing cut-out pocket to achieve electrical release functionality
2Extent of automation
If a prior art electric strike with a rotatable keeper is used, then the door can be released electrically, but the cut-out pocket must be significantly enlarged increasing installation time and cost
Solution Approach 1:
The strike housing and keeper mechanism are designed to fit within the standard cut-out pocket dimensions used for traditional strikes, making the electric strike universally installable in existing door frames without requiring enlargement of the cut-out pocket or creation of new mounting points
3Ease of manufacture
If a standard strike is used, then the cut-out pocket remains standard size, but controlled access through key fobs, key cards, or key pads is not supported
Solution Approach 1:
The electric strike mechanism integrating the actuating mechanism, blocking member, and rotatable-translating keeper is designed to fit within the standard cut-out pocket dimensions, merging the electrical release functionality with the existing standard strike opening without requiring enlargement

AI summary
An electric strike for use with a sliding door is provided. The strike comprises a housing defining a cavity including first and second walls, each having first and second slots defined therein. A keeper is disposed within the cavity and movable between latched and unlatched positions. The keeper includes first and second ends, wherein each includes respective outwardly extending first and second keeper pins. The first and second keeper pins extending from each end of the keeper are disposed in the respective first and second slots. A blocking member is pivotably mounted to the housing and includes first and second portions. The second portion of the blocking member is engaged with the first keeper pin when the first portion of the blocking member is selectively engaged with a plunger of an actuating mechanism in the first engaged position to selectively maintain the keeper in the latched position.
