Folding Table Lock Mechanism for Compact Under-Table Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding tables with link and lock mechanisms are bulky, complex, and require space below the table for unfolding, limiting their compactness and effective use of space.
Innovation Solution
A folding table design featuring a table frame with a pivotable support member and a lock mechanism integrated within the table body, utilizing a first and second engagement member with a lock biaser to securely hold the frame in place without exposing supporting components below the table, allowing for a compact and space-efficient configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a link and lock mechanism are used to support the table body in an extended state, then the table can be locked in the in-use position, but the structure becomes large and complex with many components
Solution Approach 1:
The patent combines the link and lock mechanism into a single integrated lock mechanism that directly connects the table frame to the support member. This merging eliminates separate components while maintaining the locking function, thereby reducing structural complexity and component count while preserving locking reliability.
Solution Approach 2:
The patent extracts the locking function from the traditional link mechanism and concentrates it into a compact lock mechanism positioned at the center of the table frame. This extraction allows the locking function to be achieved with fewer components and reduced structural complexity.
2Reliability
If the link and lock mechanism span downward from the lower side of the table body, then the table can be supported in the in-use position, but the space below the table body cannot be used effectively
Solution Approach 1:
The patent repositions the lock mechanism from the lower side of the table body to the center of the table frame in the vertical dimension. This dimensional change allows the locking mechanism to be located above the table body, freeing up the space below the table for effective use while maintaining support reliability.
3Adaptability or versatility
If the table structure is changed depending on design requirements, then the table can meet specific design needs, but it becomes necessary to manufacture the top surface portion and link from different members
Solution Approach 1:
The patent designs the table frame with a standardized central lock mechanism that can accommodate various design requirements without requiring custom manufacturing of the top surface portion or link. The universal lock mechanism design allows different table configurations to use the same core components, reducing manufacturing costs while maintaining design adaptability.
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 design results in a thinner, lighter, and more cost-effective folding table that can be easily switched between use and stowed positions without needing additional space for unfolding, ensuring secure locking and efficient use of space below the table.
Implementation Method 1
a lock biaser; wherein the first engagement member and the second engagement member are configured to be capable of engaging and disengaging by one of the first engagement member and the second engagement member being moved, and the lock biaser biases the first or second engagement member that is moved in a direction of engagement
Implementation Method 2
a support member that pivotably supports one end of the table frame

AI summary
A folding table is provided that includes: a table frame that enables a table body to move between the in-use position and the stowed position, that is disposed within the table body, and that supports the table body; a support member that pivotably supports the table frame; and a lock, provided in a position where the support member and the table frame are linked, that holds the table frame in the in-use position and prevents the table frame from pivoting. The lock has: a retaining member in which an engagement groove is formed; a pivoting member capable of engaging with and disengaging from the engagement groove; and a lock biaser that biases the pivoting member in the direction of engagement with the engagement groove.
