Locking Bolt Axial Adjustment Anti-Theft Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking bolts are difficult to handle, especially in tight spaces, and lack protection against theft since the part that releases the connection must be freely accessible, allowing unauthorized access.
Innovation Solution
A locking bolt with a radially adjustable retaining means and a second recess for holding means, allowing axial adjustment from the end opposite the closing part, ensuring the bolt remains in the open position during insertion and providing protection against theft by preventing radial movement of locking means, thus securing the object effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking means are adjusted radially outwards in the inserted state, then the locking pin cannot be removed from the component openings and the components are firmly connected, but the bolt must be manually adjusted axially against the spring force which is disadvantageous for handling in difficult-to-access spaces
Solution Approach 1:
The patent introduces an intermediary mechanism (the spring-loaded bolt with radial locking means) that automatically engages the locking means radially outwards upon insertion, eliminating the need for manual axial adjustment against spring force. The intermediary mechanism mediates between the insertion action and the locking state, providing automatic engagement.
Solution Approach 2:
The locking means are preliminarily positioned on the bolt such that upon insertion into the component opening, they automatically adjust radially outwards to engage with the component opening walls before the bolt is fully inserted. This preliminary radial adjustment ensures locking reliability is established before final insertion completion.
2Ease of operation
If the bolt is made freely accessible from the end pointing towards the closing part for removal and insertion, then handling is simplified, but the locking bolt cannot protect against theft since the release mechanism is accessible to unauthorized third parties
Solution Approach 1:
The patent inverts the conventional approach by making the end pointing away from the closing part (the opposite end) the accessible end for both insertion and release operations. This inversion maintains handling ease while simultaneously protecting against theft, as unauthorized parties cannot access the release mechanism from the closed side.
Solution Approach 2:
The bolt structure acts as an intermediary that transmits the release force from the accessible end through its length to the locking means, allowing operation from the opposite end without compromising the security of the closing part side. The intermediary bolt body ensures the release action is transmitted effectively despite the reversed access configuration.
3Reliability
If the locking means are adjusted radially outwards to prevent removal, then secure connection is achieved, but the bolt must be manually moved axially into the open position which complicates operation
Solution Approach 1:
The patent employs a dynamic spring-loaded bolt that can move axially between locked and open positions. The spring force dynamically adjusts the bolt position, allowing automatic radial adjustment of locking means upon insertion while maintaining the ability to release by simple axial movement from the opposite end, reducing operational complexity.
Solution Approach 2:
The locking means automatically adjust radially outwards upon insertion without requiring manual intervention, achieving self-locking. The spring mechanism provides self-service by automatically positioning the bolt and locking means to secure the connection, eliminating the need for complex manual adjustment procedures.
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 handling by allowing axial adjustment from the opposite end, ensuring the locking bolt remains in the open position during insertion and provides effective protection against theft by preventing unauthorized access to the release mechanism.
Implementation Method 1
the bolt is generally acted upon by a spring which causes the bolt to be displaced into the blocking position
Implementation Method 2
The adjusting sleeve 13 is acted upon by a second restoring element 14, which is formed by a second spiral spring 22

AI summary
The invention relates to a locking bolt with a bolt (3) axially adjustable in a guide housing (2) between a locked position and an open position, with at least one locking element (8) radially adjustable in a locking opening (7) formed in the guide housing (2), which in the open position is engaged in a first recess (10) formed in the bolt (3) and which in the locked position is radially adjusted by the bolt (3) in the locking opening beyond the outer circumference of the guide housing (2), and with a closing element (5) associated with the guide housing (2) and limiting its insertion depth into a component opening. At least one radially adjustable retaining element (12) is provided for axially fixing the position of the bolt (3) in the open position by means of an adjusting sleeve (13) axially adjustable on the guide housing (2).In addition, the bolt has a second recess (15) for receiving the at least one retaining element (12) in the open position.
