Abstract
Description
1. Title of the invention
[0001] Attachment for use with a drive tool for opening a mechatronic locking system.
[0002] Attachments for the non-destructive opening of mechatronic electronic profile knob cylinders (RFID / transponder / combination / biometric locks) according to DIN 18252 and DIN EN 15684 (possibly also DIN EN 1303). This also includes complete locks from Asia that can be opened electronically and / or mechatronically (generally mechatronic profile knob cylinders) using Bluetooth, RFID, combination codes, biometrics, or other methods. This can be achieved through radial or axial attacks via design features using a rotary tool with a striking mechanism (e.g., impact drill, impact wrench, rotary hammer, etc.). 2. Technical field
[0003] The invention relates to a physical attachment for use with a drive tool for opening mechatronic locking systems. The attachment is designed to act on an external actuating element in order to enable opening without structural damage to the locking system. Methodological aspects are described solely for the purpose of explaining the mode of operation.
[0004] The invention relates to a soft or rigid attachment (e.g., silicone, TPU, plastic, or other material) that, in conjunction with a rotary impact tool, can non-destructively open a mechatronic profile knob cylinder by utilizing certain design features of the internal components (e.g., clutch and actuator) as an attack vector. The attachment is driven by a rotary impact tool and transmits rotation, impacts, and vibration to the mechatronic profile knob cylinder to unlock it. This enables a fast, efficient, and non-destructive opening technique that can be used, for example, by locksmiths. 3. State of the art
[0005] Electronic locking systems, in particular mechatronic profile knob cylinders according to DIN 18252 and DIN EN 15684 standards, are increasingly used in private and commercial security-relevant areas. Their locking process is generally carried out via electronic authentication (mostly via RFID, NFC, Bluetooth, numeric combination, or biometrics), for example, using codes, cards, transponders, or biometric data. The internal mechanism that controls locking and unlocking often consists of an actuator (e.g., a small motor or electromagnet), a mechanical spring, and / or a coupling that connects electronic components to the mechanical parts.
[0006] Current methods for the emergency opening of such mechatronic profile knob cylinders are often destructive and result in the destruction of the locking system or the door. Techniques such as drilling, milling, picking, or other forced entry are common, but involve high costs and effort for subsequent repairs. Non-destructive methods are often limited to specific lock models and require highly specialized tools and expertise.
[0007] There is therefore a need for a universally applicable device that makes it possible to open a large number of mechatronic profile knob cylinders quickly and non-destructively by specifically acting on their internal mechanics. Background and Problem Statement
[0008] Similar methods were presented at the Chaos Computer Club event called “MCH 022 Electronic_Locks_Bumping_and_Other_Mischief” and under the YouTube search term “Opening electronic Lock with Percussion Drill”, but these are not flexible and consist of several parts or do not have safety distances.
[0009] Defining a component, defining its dimensions, describing the materials, introducing a safety barrier to avoid excessive mechanical stress on the mechatronic profile knob cylinder, and designing the form all highlight the new features. 4. Object of the invention
[0010] The object of the invention is to provide a universally applicable attachment that enables the non-destructive opening of mechatronic locking systems by means of a rotary tool with impact mechanism (e.g. impact drill, impact wrench, rotary hammer or similar).
[0011] In particular, it is designed to prevent the use of standard, destructive tools by locksmiths by specifically exploiting a design-related attack vector. The attachment merely serves to transfer corresponding types of movement or operating principles (rotational, impact, and vibration impulses) to the internal mechanics of the mechatronic profile knob cylinder. 5. Solution to the task
[0012] This task is solved by an article containing the features of claim 1. Advantageous embodiments are the subject of dependent claims.
[0013] The invention proposes a one-piece attachment that acts as an adapter between a rotary tool with a percussion mechanism and the knob of a mechatronic profile knob cylinder. The attachment has a tool receptacle and an opposing knob receptacle. The knob receptacle is shaped to engage the knob of the cylinder in a form-fitting or force-fit manner.
[0014] The solution lies in manufacturing the attachment from a specifically selected material whose elasticity and damping properties are tailored to modify and transfer the rotational, impact, and vibrational impulses generated by the tool to the cylinder knob in a way that allows manipulation of the internal coupling mechanism. By selectively introducing vibrations and impact impulses, the coupling or actuator connecting the knob to the locking mechanism is momentarily disengaged or set into a state where manual or tool-assisted rotation of the knob results in opening. Preferred embodiment
[0015] In a preferred embodiment, the attachment is made of a thermoplastic polyurethane (TPU) or a similar elastomer with a defined Shore hardness. This choice of material ensures that the high-energy impacts of the tool are dampened and converted into a vibration frequency effective for the internal mechanics, without causing external damage to the cylinder. Optional versions
[0016] Optionally, the knob receptacle can have an internal geometry with ribs, studs, or other structures to optimize impulse transmission and ensure better adhesion to the knob. Furthermore, an integrated safety barrier in the form of a circumferential material thickening or a stop can be provided. This limits the axial penetration depth of the attachment onto the cylinder, thus preventing excessive mechanical stress on the cylinder housing and the electronics within it. 6. Advantages of the invention: Non-destructive application
[0017] Unlike conventional emergency opening methods such as drilling or milling, the mechatronic profile knob cylinder remains fully functional. There are no costs for replacement or repair. Universal applicability
[0018] Due to its simple yet effective mode of operation and the possibility of producing attachments with different knob mounts, the invention is applicable to a wide range of cylinder models from various manufacturers. Simple and quick handling
[0019] The application requires no special expertise regarding the internal structure of the respective lock. The attachment is simply placed on a standard rotary tool and positioned on the cylinder knob, allowing it to be opened in seconds. Cost efficiency
[0020] Manufacturing the attachments, for example using 3D printing with TPU, is extremely cost-effective. Users such as locksmiths can utilize existing standard tools (impact wrenches, etc.). Safety and controllability
[0021] The integrated safety wall and the material properties of the attachment prevent accidental damage to the lock by the user. The force applied is directed specifically to the internal mechanism. QUOTES INCLUDED IN THE DESCRIPTION
