Pivoting Nail Magazine With Peripheral Tray Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail magazines for power-operated nailing tools face challenges in accommodating nails of different lengths due to bulkiness and complexity in loading processes, and existing adjustable designs often compromise on usability or are prone to loss.
Innovation Solution
A cylindrical coil magazine with a pivotally interconnected body and a swingingly mounted tray on a central pivot pin allows for easy loading and adjustable height to accommodate various nail lengths, with locking mechanisms for secure positioning and easy attachment to the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable tray on a centre post is provided for adjusting nail length, then the magazine can accommodate different nail lengths, but the loading process becomes complicated and the magazine becomes bulky
Solution Approach 1:
The invention removes the centre post that was previously required to support the movable tray. Instead, the tray is mounted on the inner peripheral surface of the magazine body, allowing the tray to be freely removed and inserted without any central support structure. This extraction of the centre post simplifies the loading process and reduces structural complexity while maintaining adjustability for different nail lengths.
2Adaptability or versatility
If a removable coil tray is provided, then the magazine can accommodate different nail lengths, but the tray can be easily lost or misplaced when not in use
Solution Approach 1:
The tray is designed with dynamic characteristics - it can be freely removed when needed for adjustment or cleaning, yet automatically retained during normal operation through engagement with the magazine body. The tray includes engagement protrusions that fit into corresponding recesses in the magazine body, providing secure retention during nailing operations while allowing easy removal when the magazine is opened for reloading.
3Ease of operation
If the tray is mounted at the outer periphery on the pivot pin, then the tray mounting does not obstruct the body, but the tray needs swing movement capability
Solution Approach 1:
The tray mounting mechanism is segmented into simple components: a pivot pin for rotational movement and engagement protrusions for positional locking. The tray is divided into a body portion and a mounting portion with the engagement protrusion, allowing independent function of each segment. This segmentation achieves swing movement capability and easy loading without requiring complex mounting mechanisms.

AI summary
A nail magazine for a nailing tool, the magazine comprising body parts pivotal between a closed condition for storing nails collated into a coil and an open position for loading with a fresh coil, and a support for the coil within the interior of the magazine, the support being adjustable axially of the magazine to accommodate different lengths of nail, wherein the support is adjustably mounted at an outer periphery whereby to provide substantially unimpeded access for loading with a fresh coil when the magazine is open.
