Reversible Latch Bolt Assembly for Correct Door Lock Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The latch bolt in multipoint locks is often installed incorrectly during assembly, necessitating disassembly and reassembly, which is cumbersome and can lead to faults, increasing costs and affecting user experience.
Innovation Solution
A latch bolt installation structure with a detachable connection between the latch part and driving part, allowing reversible assembly by providing a female part with two installation positions and an elastic-engaging mechanism for secure attachment, facilitated by an adjusting mechanism for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the latch bolt is disassembled and reassembled to correct installation errors, then the installation correctness can be improved, but the construction time and complexity increase significantly
Solution Approach 1:
The latch bolt is divided into separate components: the latch part and the driving part. These components can be independently installed and adjusted, allowing for easy correction of installation errors without requiring complete disassembly of the entire lock mechanism.
Solution Approach 2:
The latch part is designed to be movable relative to the driving part, enabling dynamic adjustment of the latch bolt's installation orientation. This allows the latch part to be repositioned between different installation states (first installation position and second installation position) without permanent disassembly.
2Reliability
If the latch bolt is disassembled and reassembled to correct installation errors, then the installation correctness can be improved, but the risk of faults and additional costs increase
Solution Approach 1:
By segmenting the latch bolt into detachable parts with standardized connection interfaces, the system reduces assembly complexity. The male part and female part design with guiding surfaces and engagement structures enables simple, error-tolerant reassembly that minimizes the risk of creating faults during correction of installation errors.
3Ease of operation
If the latch part is detachably connected with the driving part, then the ease of adjustment is improved, but the device complexity increases
Solution Approach 1:
The detachable connection divides the latch bolt into independent parts that can be easily separated and reconnected. This segmentation provides ease of adjustment while keeping each component relatively simple in structure.
Solution Approach 2:
The connection structure serves multiple functions: it enables easy detachment and reattachment for adjustment, provides guiding surfaces for accurate alignment, includes engagement structures for secure connection, and allows for orientation reversal. This multi-functionality achieves ease of adjustment without proportionally increasing structural complexity.

AI summary
The present invention relates to the field of lockset and provides a lock body a latch bolt installation structure comprising a latch bolt body having a driving part and a latch part, wherein the latch part is detachably connected with the driving part. The latch part is configured with a male part inserting into a female part on the driving part; the female part comprises a first installation position and a second installation position for installing the latch part; when the latch part is installed at the first installation position, a flat surface of the latch part faces towards a first direction; when the latch part is installed at the second installation position, the flat surface of the latch part faces towards a second direction which is opposite to the first direction. The present invention is advantageous in fast reversal of the installation of the latch bolt as well as the construction progress control and user experiences.
