Folding Tent Leg Tube Locking With Safer Press-Sheet Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding tents require direct contact with a jump bead for unlocking during folding, leading to hand clamping issues and potential injuries, as well as psychological discomfort, making the process cumbersome and intimidating.
Innovation Solution
A leg tube sliding locking mechanism featuring a sliding support, a V-shaped spring, and a bushing with a pressing sheet that covers the jump bead, allowing the tent to be folded and contracted without direct pressure on the jump bead, using a large-area pressing sheet for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the jump bead is directly pressed for unlocking during folding, then the unlocking function is achieved, but hand clamping occurs and potential injuries are caused
Solution Approach 1:
The patent introduces a pressing sheet as an intermediary component between the operator's hand and the jump bead. The pressing sheet is connected to the jump bead through a connecting structure, allowing the operator to press the pressing sheet rather than directly pressing the jump bead. This intermediary mechanism transfers the pressing force while preventing direct contact with the small, hard jump bead, thereby eliminating hand clamping and injury risks while maintaining the unlocking function
2Device complexity
If the jump bead is directly pressed for unlocking, then the structure remains simple, but psychological discomfort and scrupulousness are caused
Solution Approach 1:
The pressing sheet serves as a mediator that provides a larger, softer pressing surface compared to the small jump bead. This intermediary structure gives operators psychological comfort by allowing them to press a larger area with their fingers or palm, reducing scrupulousness and fear of pressing. The connecting structure maintains the overall simplicity of the device while adding this beneficial intermediary element
3Object-affected harmful factors
If a pressing sheet is introduced to cover the jump bead, then hand clamping is prevented, but device complexity increases
Solution Approach 1:
The pressing sheet is connected to the jump bead through a simple connecting structure that may consist of basic mechanical elements. This intermediary system prevents hand clamping by providing a larger pressing surface while adding minimal structural complexity. The connecting structure allows the pressing sheet to move and transmit force effectively without requiring complex mechanisms
Solution Approach 2:
The unlocking mechanism is segmented into distinct functional components: the jump bead for locking, the pressing sheet for safe operation, and the connecting structure for force transmission. This segmentation allows each component to perform its specific function optimally while maintaining overall system simplicity and preventing hand clamping
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
Prevents hand clamping and reduces the risk of injury by eliminating direct contact with the jump bead, facilitating easier and safer opening and closing of the tent.
Implementation Method 1
a V-shaped spring, one end of the V-shaped spring is connected to the jump bead, the other end of the V-shaped spring is fixed to an inner wall of the leg tube

AI summary
A leg tube sliding locking mechanism for opening and closing a folding tent includes a sliding support sleeved on a leg tube, a jump bead, and a V-shaped spring. One end of the V-shaped spring is connected to the jump bead, and the other end of the V-shaped spring is fixed to an inner wall of the leg tube. A bushing is installed on an inner wall of the sliding support in a fitted manner.An upper end of the busing extends downward to form a pressing sheet, and the pressing sheet has a lower end extending outwards to a lower end of the sliding support. The pressing sheet covers the jump bead.
