Tiltable Stick Handle Loop Fastening for Secure Strap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole handles for hiking, trekking, ski, and Nordic walking poles lack a modular and adjustable design that allows for easy assembly, repair, and replacement of components while ensuring secure retention and easy length adjustment of the hand strap.
Innovation Solution
A pole handle design featuring a loop fastening element and hand strap that form a modular unit, tiltable about a rotation axis, allowing for adjustable strap length through a frictional connection without positive locking holes, and a core structure with lattice openings for stability and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the loop fastening element is fixed in the handle head, then the strap retention is secure, but the strap length cannot be adjusted
Solution Approach 1:
The loop fastening element is designed to be tiltable relative to the handle head, transitioning between a fixed position (providing secure retention) and an adjustable position (allowing strap length modification). This dynamic positioning resolves the contradiction by making the system adaptable between two functional states.
Solution Approach 2:
The loop fastening element is separated from the handle head core, allowing independent movement and adjustment. This segmentation enables the fastening element to be tilted for adjustment while remaining connected, resolving the contradiction between fixed retention and adjustable length.
2Device complexity
If the loop fastening element is integrated into the handle head, then the structure is compact, but assembly and repair are difficult
Solution Approach 1:
The loop fastening element is designed as a separate component that can be tilted and removed from the handle head core. This segmentation maintains a compact overall structure while enabling easy assembly and repair by allowing the fastening element to be independently accessed and replaced.
Solution Approach 2:
The tiltable connection between the loop fastening element and handle head provides dynamic access to the fastening element. This allows the element to be tilted out for repair or replacement while maintaining a compact integrated appearance during normal use, resolving the contradiction between compactness and ease of repair.
3Reliability
If positive locking holes are used for strap attachment, then the strap retention is secure, but the adjustment flexibility is reduced
Solution Approach 1:
The loop fastening element uses a tiltable connection instead of fixed positive locking holes. This dynamic mechanism allows the strap to be secured reliably in the fixed position while providing flexible adjustment capability when tilted, resolving the contradiction between secure retention and adjustment flexibility.

Function Achieved in This Case
Facilitates simple assembly, repair, and replacement of components, ensuring secure strap retention and easy length adjustment, while optimizing production and inventory management, and providing enhanced grip comfort and stability.
Implementation Method 1
the size of the hand strap cannot be adjusted, namely by the band of the hand strap being fixed in a force-fitting and not a form-fitting manner

AI summary
The invention relates to a pole handle (1), in particular for a ski pole, cross-country ski pole, trekking pole, or Nordic walking pole, comprising a central receiving area (11) that at least partly receives a loop fastening element (5) with a hand loop (4), which is secured to the loop fastening element (5) and has an adjustable size. The invention is characterized in that the loop fastening element and the hand loop (4) secured to the loop fastening element (5) form a modular unit which is formed separately from a core (1a) of the pole handle (1) and which is secured to the core (1a) of the pole handle (1) in a reversibly tiltable manner about a rotational axis (D) in the pole handle (1), wherein the loop fastening element (5) can be tilted from a rest position (X1), in which the loop fastening element (5) is integrated into the surface contour of the handle head and in which the size of the hand loop (4) cannot be adjusted, upwards about the rotational axis (D) into an adjustment position (X2), in which the size of the hand loop (4) can be adjusted.
