Drive-in Device Magazine Retaining Part Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive-in devices for fastening means, such as staples or nails, face delays in reloading due to complex and time-consuming unlocking of the slider mechanism, which can take up to 5 seconds, especially when protected by a glove.
Innovation Solution
An adjustable retaining part with an obliquely running sliding surface on the magazine carrier allows for simple locking and unlocking of the slider, eliminating the need for separate actuation, enabling quicker reloading by displacing the staple strip and using a spring element to move the slider back, along with an optional trigger for assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slider is locked in the undercut of the magazine carrier for magazine loading, then the magazine can be loaded with fastening means, but the unlocking process becomes time-consuming and complex requiring manual manipulation that may be protected by gloves
Solution Approach 1:
The component section is pre-configured with an oblique sliding surface that automatically engages the slider during the magazine loading process. When the magazine carrier is inserted, the sliding surface automatically pushes the slider into the locked position, eliminating the need for manual unlocking operations and reducing the time loss associated with glove protection.
Solution Approach 2:
The locking function is extracted from the manual operation and integrated into the magazine carrier structure itself. The component section on the magazine carrier performs the locking action automatically during insertion, removing the need for separate manual locking and unlocking steps that were previously required.
2Ease of operation
If a separate unlocking mechanism is provided for the slider, then the slider can be unlocked after magazine loading, but the device complexity increases with additional components and actuation mechanisms
Solution Approach 1:
The magazine carrier performs the unlocking function automatically through its own structure. The oblique sliding surface of the component section self-actuates to push the slider out of the locked position during the normal magazine insertion and fastening means feeding process, eliminating the need for separate unlocking mechanisms or manual intervention.
Solution Approach 2:
The magazine carrier is designed to perform multiple functions: it holds the fastening means, guides the slider into the locked position during loading, and automatically unlocks the slider during the feeding process. This multi-functionality eliminates the need for separate dedicated locking and unlocking mechanisms, reducing overall device complexity.
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
The solution simplifies the loading process by allowing immediate unlocking after magazine filling, reducing operational time and ensuring reliable form closure and disengagement, enhancing the device's operational efficiency and user convenience.
Implementation Method 1
the slider is moved back by the feeding element thereof, which is designed, for example, as a scroll spring

AI summary
The invention relates to at least one device for placing fastening means, in particular a drive-in device, comprising at least one magazine for the fastening means to be placed which are accommodated by means of a magazine carrier, wherein a lockable slider is movably held along the magazine carrier, said slider being coupled to a feeding element for a movement of the fastening elements into an operating position below a firing pin. In order to be able to make an advantageous locking and unlocking of the slider during loading of the magazine, an adjustable retaining part for locking the slider is disposed on the magazine carrier, which retaining part has, in its locking position, at least one component section which protrudes into the feed path of the slider for a form closure with the slider in its locking position, wherein the component section has at least one sliding surface running obliquely to the guide surfaces of the magazine carrier for shifting the retaining part from the locking position. At the same time, the retaining part has a shoulder running approximately perpendicularly to the guide surfaces of the magazine carrier, which is configured so that it directly adjoins the obliquely running sliding surface.
