Tent Frame Eave Pole Sliding Sleeve Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tent frames with eave structures are complex, require additional poles and elements, and are not convenient to use, as they increase the size and weight when folded and do not allow eave poles to fold or unfold with the main frame.
Innovation Solution
A tent frame design featuring a supporting pole, upper pole, oblique pole, sleeve member, and eave pole, where the eave pole is pivotally connected to the oblique pole and slidably coupled with the sleeve member, allowing the eave pole to extend outwardly when unfolded and retract when folded, simplifying the structure and enabling compact folding.

Engineering Contradiction Analysis
1Area of stationary object
If eave supporting frame with two poles and sliding block is used to provide larger shading area, then the shading area is increased, but the structure becomes more complex and the folded size increases
Solution Approach 1:
The patent extracts and eliminates the sliding block component from the eave supporting frame structure. By directly pivotally connecting the eave pole to the upper frame without requiring a sliding block, the invention simplifies the structure while maintaining the ability to provide extended shading area when unfolded.
Solution Approach 2:
The invention merges the eave pole connection mechanism with the existing upper frame structure. The eave pole is pivotally connected directly to the upper frame at a pivotal connection point, combining the eave support function with the main frame structure rather than using separate sliding blocks and auxiliary poles.
2Ease of operation
If eave poles are made to fold and unfold with the main frame, then the ease of operation is improved, but the structure becomes more complex
Solution Approach 1:
The eave pole is integrated with the main frame through a pivotal connection point on the upper frame, allowing both structures to fold and unfold together as a single unit. This merging eliminates the need for separate manual operation of eave poles while maintaining structural simplicity.
Solution Approach 2:
The pivotal connection allows the eave pole to dynamically adjust its position relative to the upper frame during folding and unfolding operations. The connection point enables automatic coordination of motion between the main frame and eave pole without requiring complex mechanical linkages.
3Stability of the object's composition
If additional supporting poles and auxiliary elements are added to support a larger upper frame, then the stability is improved, but the weight increases
Solution Approach 1:
The invention segments the eave support function from the main supporting structure. By using a dedicated eave pole with pivotal connection rather than adding multiple auxiliary supporting poles, the design provides necessary stability for extended shading areas while minimizing additional weight through functional segmentation.

AI summary
Disclosed are eave structures and tent frames with integrated eave structures. A tent frame includes supporting poles, an upper frame coupled with the supporting poles, and two or more eave structures. An eave structure includes an eave pole, and a sleeve member disposed at a connector coupled with a supporting pole. The eave pole has a first end portion pivotally connected with an oblique pole of the upper frame, and a second end portion slidably coupled with the sleeve member. The eave structures can be folded and unfolded together with the supporting poles and the upper frame. When unfolded, the eave poles of the eave structures extend beyond the upper frame.
