Telescopic Support Leg Locking for One-Turn Tripod Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telescopic support legs in camera tripods have complicated operations and slow adjustment due to multi-point independent adjustments, which are time-consuming and cumbersome.
Innovation Solution
A telescopic support leg design featuring axially telescopic and circumferentially fixed top, middle, and bottom tubes, with a locking control mechanism that includes a rotating rod and multiple locking members, allowing simultaneous locking and unlocking of the tubes with a single turn, enhancing operational simplicity and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-point independent adjustment is used for support legs, then each section can be adjusted independently, but the operation becomes complicated and adjustment speed decreases
Solution Approach 1:
The patent combines multiple independent locking mechanisms into a single integrated locking system. The locking component includes a rotating rod that simultaneously controls locking members for multiple leg sections, allowing all sections to be locked or unlocked together through one operation rather than requiring separate adjustments for each section.
Solution Approach 2:
The locking control member serves multiple functions: it simultaneously locks and unlocks multiple leg sections, provides circumferential fixing between tubes, and enables both telescopic adjustment and stable positioning. This multi-functional design eliminates the need for separate mechanisms for each adjustment point.
2Adaptability or versatility
If multi-point independent adjustment is used for support legs, then each section can be adjusted independently, but the adjustment time increases
Solution Approach 1:
The patent combines multiple independent locking mechanisms into a single integrated locking system. The locking component includes a rotating rod that simultaneously controls locking members for multiple leg sections, allowing all sections to be locked or unlocked together through one operation rather than requiring separate adjustments for each section.
Solution Approach 2:
The locking members are pre-positioned within the leg tubes, and the rotating rod is pre-configured to engage all locking points simultaneously. When the user rotates the rod, the action is already prepared to lock or unlock all sections at once, eliminating sequential adjustment time.
3Device complexity
If traditional telescopic adjustment mechanism is used, then the structure is simple, but the locking and unlocking operations are cumbersome
Solution Approach 1:
The rotating rod acts as an intermediary component that transmits the user's rotational input to multiple locking members simultaneously. This intermediary mechanism converts a simple rotational motion into coordinated locking or unlocking actions across multiple leg sections, maintaining structural simplicity while dramatically improving operational ease.
Solution Approach 2:
The locking members are designed to automatically engage with the leg tube features when the rotating rod is turned. The system uses the existing structural features of the tubes themselves as part of the locking mechanism, requiring minimal additional components while achieving efficient locking and unlocking operations.

AI summary
Aspects of the invention disclose a telescopic support leg, which includes a top leg tube, a middle leg tube and an bottom leg tube that are arranged sequentially from outside to inside. A first locking member includes a movable tube and a limiting plate, with a middle inner brace and an outer brace. A second locking member includes an inner tube and an elastic sleeve. The middle leg tube is secured to the inner support while moving relative to the inner tube, thereby allowing the elastic sleeve to function as the inner tube lock the outer wall of the bottom leg tube or loosen the elastic sleeve and the inner tube of the bottom leg tube.
