Toggle Lever Clamping Device for Floorboard Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for aligning floorboards during laying are cumbersome and time-consuming due to the need for manual monitoring and adjustment of joint distances, especially with high spring force floorboards, which requires frequent clamping and unclamping processes.
Innovation Solution
A clamping device with a lever mechanism and adjustable pressure cheeks that allows for a defined joint distance setting, enabling quick and efficient alignment by maintaining a consistent clamping position without the need for continuous measurement, using a toggle lever principle and adjustable screw connections for fine and coarse adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tensioning systems (tension belts, screw clamps) are used to handle high spring force of floor boards, then the floor boards can be aligned and fastened, but the clamping position is completely undefined and unlimited, requiring continuous monitoring of joint distance with a joint gauge, making the alignment process cumbersome and time-consuming
Solution Approach 1:
The patent applies parameter changes by providing a clamping device with an adjustable clamping distance that can be set to match specific floor board dimensions. The device includes adjustment mechanisms (threaded rods, lockable positions) that allow the clamping distance parameter to be changed according to different board widths and joint requirements, eliminating the need for continuous measurement during the alignment process
Solution Approach 2:
The patent implements preliminary action by pre-setting the clamping distance to the required value before the alignment operation begins. The clamping device is prepared with the correct distance configuration in advance, so that when applied to the floor boards, the joint distance is automatically correct without requiring ongoing monitoring or adjustment during the fastening process
2Reliability
If the clamping device must be left or locked during each attachment to attach the floor board to the substructure, then the board can be fastened, but the process must be repeated several times over the length of the floorboard, making alignment very cumbersome and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the clamping device into modular components that can be independently adjusted and positioned. The device includes separate adjustment mechanisms for each clamping point, allowing the system to maintain proper spacing across multiple boards without requiring repeated locking and unlocking operations
Solution Approach 2:
The patent implements universality by designing a clamping device that can handle multiple floor boards simultaneously with a single positioning action. The adjustable clamping mechanism works universally across different board widths and positions, allowing the worker to clamp and fasten multiple boards in sequence without resetting the device for each individual board
3Adaptability or versatility
If a multi-part, length-adjustable rod with pressure jaws and threaded adjustment mechanisms is used, then the clamping device can be adjusted to different positions, but the structure becomes complex with multiple rod sections, levers, and threaded components
Solution Approach 1:
The patent applies the nested doll principle by incorporating telescopic rod sections that nest within each other. The inner rod section slides within the outer rod section, allowing length adjustment without requiring separate modular components to be assembled. This nested structure provides adaptability while minimizing the number of discrete parts and reducing overall structural complexity

AI summary
The device (1) has an eye-shaped binder element (40) that is arranged at a free end of a tension lever (26). The tension lever is suspended in a receiving part (42) that is detachably connected with a guide part (22) such that the binder element is rotated in a released state for fine adjustment of a screw (32). The screw is locked with a pressure part (12) that is connected with another guide part (20). A retaining part (44) is connected with the latter guide part for variable distance adjustments.
