Definitions
- the invention relates to a hollow securing element, for example a clip.
- the invention further relates to a lock, for example a padlock or a bicycle lock, with the security element and a locking device.
- the invention also relates to a method for manufacturing the security element and a method for manufacturing the lock.
- the invention also relates to and a method for impeding a theft attempt.
- a lock as an anti-theft device is used in a wide variety of designs to secure objects such as bicycles or other movable objects.
- a lock as a padlock as is the case, for example, in the DE 100 34 172 A1 is described, is used to close simple closures, such as cellar doors, lockers, tool boxes, garden fences, shutters, chests, etc. All these locks are equipped with a security element, such as a bracket.
- the DE 20 2008 016 698 U1 an anti-theft device for bicycles, in which the security element and the locking device have a common cavity with a signal medium arranged therein.
- the signal medium emerges when the cavity is opened.
- a break-in or destruction of the anti-theft device is immediately recognizable by the emerging signal medium.
- the signal medium is an insoluble or difficult-to-remove dye that gets onto the objects to be protected and marks them if the anti-theft device is destroyed. Stolen objects are thus easily recognizable.
- An overpressure or a negative pressure is provided in the cavity, as a result of which the signal medium escapes explosively when the cavity is damaged or opened and is distributed over a large area.
- a safety device for bicycles in which one end is fixedly attached to the lock body.
- a signaling device (blanket primer, chemical reaction capsule) is activated by a trigger wire inside the security device when a theft attempt is made.
- WO 2017/152100 A1 is a rigid bicycle lock with a hollow U-shaped tube as a security element (lock shackle) and a locking device, both pressurized with a chemical substance to prevent theft. In the event of an attempted theft, this chemical substance escapes and causes visual impairment, shortness of breath or unwanted bodily reflexes such as vomiting etc. in the potential thief.
- An insert is attached to each of the two ends of the fuse element. Each insert is shaped at the outer end to fit into a corresponding opening of the closure device to be locked in place by a locking mechanism.
- FIG 5 this description shows the figure 5 the WO 2017/152100 A1 . In the figure 5 one of the two inserts 306 and one end of the tube 202 is shown in perspective sectional view.
- Each insert 306 has a recess 504 which is press fitted or threaded to a tapered end 502 of the tube 202 and combined with a welding or adhesive operation to ensure a permanent, strong and fluid tight connection.
- Each insert 306 forms a check valve with a coil spring 512, a valve ball 510 and a press-fit retaining insert 508.
- the check valve is an integral part of the insert and leads to a hole 506 through which the tube 202 is filled with the chemical substance. Once tube 202 is filled, hole 506 is permanently sealed.
- the filling takes place automatically and during the manufacturing process.
- the lock shackle is fixed in a special device for this purpose. Only with such a fixation can the filling be done by primitive connections such as a press fit.
- the means of protection used are highly aggressive and sometimes dangerous. Therefore, the refilling of the protective agent (signal medium or chemical substance) has not been provided so far.
- the lock over a long period of time, for example several years or decades, inevitably leads to part or all of the pressure of the protective agent escaping from the cavity. So the lock loses its additional protective function or at least the function of the sudden escape of the protective agent. Even if you wanted to refill the lock manually, there would be no refilling access in the tube.
- both ends of the security element are always terminated with the complex and special insert.
- These inserts are recessed for closure, with very little tubing between the recess and cavity. This pipe material is further reduced by frequent opening/closing, so that there is a risk that the cavity will be opened unintentionally during a closing process and the user will come into contact with the protective means.
- the ends of the securing element are either solid and/or they are completely free of the protective means due to the positioning of the closures of the cavity. If the security element were to be destroyed in an area close to one of the ends, no protective agent would escape and the lock would not achieve the desired effect (release of the protective agent).
- the object of the present invention is to provide a security element that is filled with a protective agent—which is under pressure—and that reliably prevents or at least adequately hinders an attempted theft.
- the security element should be easy to produce and refillable quickly and easily.
- a user should always be safe from avoiding protective agents.
- the cavity for the protective means should be maximized so that the materials for the security element no longer have to meet the high stability requirements and can therefore become more cost-effective.
- the object is achieved by a hollow securing element having a locking end arranged for temporary locking in a locking device in dependence on a locking mechanism of the locking device; a filling end set up for at least temporarily storing the securing element in the locking device; a cavity arranged between the closing end and the filling end, in which a pressurized fluid is introduced as a protective means, the cavity at the filling end being closed off by a filling valve at the filling end for introducing the fluid into the cavity, i.e. at least is lockable at the time the fluid is introduced into the cavity, and wherein the filling end has a threaded insert for fixing the filling valve to the filling end.
- a lock preferably a padlock or a bicycle lock, which has a security element according to one of the preceding types and a locking device with a locking mechanism, with a locking end of the security element in the locking device depending on the locking mechanism of the locking device can be locked and wherein a filling end of the securing element is mounted in the locking device.
- the types of lock possible for the security element according to the invention are diverse, for example a padlock, a brake disc lock, a bicycle lock, a bolt lock, a round shackle lock, a folding lock, etc. can be equipped with the security element according to the invention.
- the securing element is hollow and in particular a hollow bracket or a hollow tube.
- the securing element has a locking end which is adapted to be temporarily locked into a locking device in response to a locking mechanism of the locking device.
- the locking mechanism includes at least two states: "open” and "closed”. A change of status is made possible, for example, by a removable lock-specific key or by setting a correct combination of numbers or a suitable biometric feature. Locking the locking end in the locking device causes the securing element to be held in place in the locking device until the status of the locking mechanism changes again to the “open” status.
- the locking device includes the locking mechanism.
- the status of the locking mechanism can be changed using a lock-specific key, a combination of numbers, spring-loaded magnets, radio signals, electromechanics, a motor drive, etc.
- the securing element also has a filling end which is set up for at least temporarily storing the securing element in the locking device.
- Mechanical restraint is generally defined as reducing degrees of freedom of movement.
- Storage can preferably also include locking.
- a storage mechanism in the closing device is set up to store the filling end in the closing device. The end of filling is prevented from moving axially, for example, or the axial movement is only permitted for a predefined path.
- the securing element is in particular prevented from being removed (removed) from the locking device.
- turning (rotating) of the securing element within the locking device is not prevented by being stored in the locking device. Storing the filling end in the closing device protects the filling end from environmental influences and unwanted venting of the cavity of the fuse element.
- Storage is permanent, for example.
- a storage mechanism within the locking device can therefore only have one state (in stock). After the security element has been installed, it cannot be permanently removed from the locking device without the locking device being destroyed. Such a mechanism is made possible, for example, by clicking the securing element once into a corresponding holder in the locking device.
- Storage is, for example, temporary.
- a storage mechanism within the locking device can have two states, namely "stocked” and "not stocked".
- a change of states is carried out, for example, by a lock-type-specific tool.
- the tool is not specific to a lock, for example an ironing tool.
- the storage mechanism is set to "storage"
- the securing element cannot be removed from the locking device.
- the filling end is inside the closing device and is not freely accessible. The filling end is thus additionally protected from environmental influences in the "stored” state and fluid is prevented from escaping from the securing element.
- the storage mechanism is set to "non-storage"
- the securing element can be removed from the locking device. In this way, the filling end of the fuse element is freely accessible.
- the security element can thus be filled/refilled at the end of the filling process. This filling can take place at fixed time intervals or after the fuse element has been repaired.
- the locking device can be of a conventional type and is, for example, a self-contained assembly.
- the securing element can have a standardized shape in order to be positioned in a conventional locking device as simply as possible. The installation of the security element can be done without great effort, since it is a separate self-contained assembly.
- the securing element comprises a cavity arranged between the closing end and the filling end, in which a pressurized fluid is introduced as a protective means.
- the cavity is closed.
- the fluid located in the cavity and under pressure cannot escape to the outside. For example, it is airtight or fluid-tight. If the cavity is opened by force, the fluid is released.
- the pressurized fluid escapes immediately and quickly, particularly explosively.
- the cavity ends in front of the closing end inside the fuse element. This ensures that the closing end is permanently closed, and any end caps or inserts can be dispensed with.
- a fluid is a liquid or a gas.
- a pressurized fluid is a fluid which has been introduced into the cavity of the fuse element at a pressure which is significantly higher than normal pressure, ie atmospheric pressure (1 bar), ie for example 2 bar, preferably 5 bar, more preferably 12 bar. Inside the cavity, the fluid preferably has a pressure of between 3 bar and 8 bar in order to ensure effective outflow. This lower limit of 3 bar enables a reliable escape if the cavity is opened without permission, for example if the security element is damaged by mechanical force. This upper limit of 8 bar makes it possible to comply with safety regulations (no unwanted leakage) during filling and/or refilling and reduces the material and tightness requirements for the safety element.
- the fluid remains in the cavity as intended without any significant loss of pressure, unless the cavity is opened again. If the cavity is opened without authorization, for example if the outer shell is damaged (severing, cutting through, clipping, sawing open) of the security element during an attempted theft, the fluid escapes quickly and reliably, for example explosively, leaving the immediate environment and the thief with the fluid, i.e the protective agent, are wetted.
- a sufficient distance is preferably provided between the closing end and the cavity.
- the fuse element consists of solid material without a cavity.
- the sufficient distance is, for example, at least as large as the diameter of the security element. In this way, a sufficiently stable locking end is obtained, which has a stably sealed cavity even after a large number of locking processes—in which the securing element is inserted into a corresponding opening of the locking device.
- the cavity is closed off at the filling end by a filling valve for introducing the fluid into the cavity, ie it can be closed off at least for the time when the fluid is introduced into the cavity (filling or refilling).
- the filling valve is arranged at the filling end and serves to close a filling hole inside the filling end by the pressure inside the cavity at least for the period of time the fluid is being introduced or also permanently until the next time the fluid is introduced.
- the filling valve is, for example, a check valve, in particular a ball check valve or a disk check valve. Such valves are hermetically sealed in the blocked direction.
- the ball check valve consists of a constriction that is closed by a ball. The ball is raised by a spring the constriction is pressed and thus closes the passage.
- the fluid can therefore not get out of the cavity through the filling end when it is closed.
- a spring ensures that the valve is blocked.
- the sealing body is designed in the form of a flat plate or dish. A bolt or pin is used for guidance.
- the filling end of the securing element has a thread, for example a threaded insert, for fixing the filling valve on the filling end.
- the valve is preferably not an integral part of the securing element or the filling end, but rather a separate component.
- the valve can therefore have its own housing.
- the valve is connected (fixed) to the fuse element during manufacture.
- the fixing is preferably permanent.
- An additional, non-detachable connection between the filling end and the valve can also be produced, for example, by means of an adhesive and/or welded connection.
- the filling end can be made significantly less complex. Only a thread is to be provided into which the valve is screwed.
- the valve has an external thread corresponding to the thread of the filling end, for example on its housing.
- a fluid under pressure is pressed against the valve and thus, for example, against the ball or the plate. If the force of the fluid exerted by the pressure exceeds the force of the spring in the valve, the fluid flows through the filling hole of the filling end into the cavity of the securing element.
- a hollow needle of a container is placed on the valve or an element (mechanism) opens the valve. The container holds the fluid. By means of a propellant or by pressurizing the fluid, the fluid flows out of the container in the direction of the valve when actuated by the hollow needle or due to the element (mechanism).
- a refilling of the cavity is made possible by the securing element according to the invention.
- the filling end is protected from environmental influences and the fluid is prevented from escaping when the security element is used as intended (opening/closing to secure movable objects or simple closures).
- the closing end is designed in such a way that even with frequent opening/closing there is no risk of the cavity being unintentionally opened during a closing process. The configurations of the closing end and the filling end therefore ensure that the user does not come into contact with the substance in an unintentional manner.
- the closing end and/or the filling end is an integral part of the securing element. It therefore consists of the same material as the securing element and does not have to be connected to the safety element separately. This saves an additional connection and eliminates a weak point in the fuse element, which is not negligible due to the pressurized cavity. The stability of the security element is increased and the complexity is reduced, as a result of which production costs can be saved.
- the closing end has a notch into which the locking mechanism of the locking device can engage for temporary locking in the locking device depending on the locking mechanism of the locking device.
- the notch is preferably in an area of the fuse element in which the cavity is not arranged.
- the distance from the notch to the cavity is preferably at least as large as the cross section of the fuse element. In this way, the locking mechanism does not impair the security that the fluid can escape from the cavity in an undesired manner due to high stress on the securing element.
- the filling end has a notch or taper, into which a bearing mechanism of the locking device can engage for supporting the securing element in the locking device.
- the protection means preferably comprises one of the following means: flue gas; tear gas or tear gas; tear or irritant fluid; ammonia with sulfur; iron sulfide with hydrochloric acid; butyric acid; signal color; and/or artificial DNA.
- the protective means preferably has a propellant in order to be able to be introduced into the cavity.
- the propellant is a non-combustible propellant, for example carbon dioxide.
- a propellant is thus used in which there is no risk of explosion if the security element is cut open without permission, for example as a result of flying sparks when using a battery-operated cut-off grinder.
- the fluid is a mixture of three of the following components.
- a first component is a non-hazardous long-lasting dye (signal color, ink) to mark a perpetrator, his tools and the potential stolen goods over a longer period of time.
- a second component is an artificial DNA in order to be able to convict the marked offender of the crime committed without any doubt.
- a third component is a non-hazardous malodorous liquid, such as a natural or food-grade liquid, which forces the perpetrator to leave the crime scene as an unpleasant-smelling place.
- the fluid is a mixture of the first component mentioned with the third component.
- the securing element is preferably a rigid bracket made of metal. This creates a solid fuse element in which the cavity is guaranteed to remain closed and the fluid only escapes if the fuse element is damaged or destroyed.
- the securing element is preferably a flexible hose which, for example, is covered with a braid or consists of a braid.
- This mesh is preferably made of a robust material such as metal, plastic, Kevlar or carbon.
- the use of a protective means introduced in the cavity of the security element makes it possible to use less expensive materials as the security element.
- the materials used can also be glass, wood or other suitable materials of the time. Specially hardened materials, such as steel, etc., can be completely dispensed with, for example, because the thief is not deterred from theft by resistant materials, but by the escaping protective agent.
- an end piece is arranged at the filling end in a detachably connected manner with the safety element for closing the cavity.
- a solid, one-piece element can serve as the end piece, for example a stopper, a stopper or a correspondingly similar closure. The end piece closes the hollow securing element and thus prevents the fluid from escaping.
- the end piece of the inflation end is preferably detachably connected to the securing element using the thread of the inflation end.
- the thread of the filling end is provided with a dual function on the one hand for fixing the thread and on the other hand for closing the securing element by the end piece.
- the thread has a length which corresponds approximately to at least the sum of the length of an external thread of the filling valve and the length of an external thread of the end piece for the filling end.
- the above-mentioned taper or notch for locking the securing element in a locking mechanism is preferably arranged between the outermost end of the end piece of the filling end and the external thread.
- the end piece of the filling end has a cavity which is part of the cavity of the security element when the end piece is connected to the security element.
- the hollow space continues to its outermost end, and separating the outer shell of the securing element in the region of the filling end also leads to the fluid escaping immediately.
- an element is preferably provided on the end piece, which element opens the filling valve for introducing the fluid into the cavity of the end piece.
- the element is, for example, a mechanical pin or bolt that opens the valve when the end piece is placed at the filling end.
- the filling channel is opened again by the element and remains open until the end piece is removed from the securing element again.
- the opened filling channel allows a small part of the fluid to flow back into the cavity of the end piece.
- the cavity preferably runs up to the above-mentioned taper or indentation, designed for the above-described at least temporary storage of the securing element in the locking device.
- the use of the end piece is particularly advantageous for very small lock shackles, for example padlocks, in order to create a large cavity for these small lock shackles as well.
- a valve adapter is arranged at the filling end.
- This valve adapter has an external thread with which it can be detachably fixed to the thread of the filling end.
- the valve adapter preferably also has an internal thread for fixing the filling valve in the valve adapter.
- the valve adapter is preferably used in order to be able to use a standard valve despite different sizes of securing elements, in particular different diameters. This increases the flexibility in the production of fuse elements of different designs and sizes.
- valve adapter can also have a taper, as a result of which the valve adapter can at least partially engage in a cavity of the end piece.
- a thread can be provided on the outside of the taper that can engage in an internal thread of the end piece. This enables a compact structure and a stable closure of the security element.
- An end piece connected to the securing element for closing the cavity is arranged at the closing end.
- a solid, one-piece element can serve as the end piece, for example a stopper, a stopper or a correspondingly similar closure.
- the end piece closes the hollow safety element at the closing end and thus prevents the fluid from escaping.
- the end piece of the closing end is non-releasably connected to the securing element, for example permanently connected by means of a joining process (welding).
- a joining process welding
- an adhesive method can also be used to permanently connect the security element and the end piece of the locking end.
- the aforesaid taper or indentation for the above-described temporary locking in a locking device depending on a locking mechanism of the locking device is arranged between the outermost end of the end piece of the locking end and the external thread.
- the tail of the locking end is releasably connected to the securing element using threads of the locking end.
- the terminus of the closing end has a cavity which is part of the cavity of the security element when the terminus of the closing end is connected to the security element.
- the hollow space continues to its outermost end and forcibly separating the outer casing of the securing element in the area of the closing end also leads to the fluid escaping immediately.
- the cavity of the end piece of the locking end runs up to the above-mentioned taper or notch for locking the securing element in a locking mechanism.
- the use of the end piece or end pieces is advantageous, particularly with very small lock shackles, for example padlocks, in order to also to create a large cavity for these small lock shackles.
- the stated object is also achieved by a method for producing a fuse element according to the preceding type with the following method steps: providing a hollow fuse element blank; introducing a thread into at least one open end of the fuse element blank; fixing a filling valve to an open end of the fuse element blank by means of the thread; shaping the fuse element blank to obtain a final shape corresponding to the final shape of the fuse element; and filling the cavity of the fuse element blank with a pressurized fluid as a protective agent at the filling valve, the filling valve automatically closing off the cavity after filling is completed.
- a hollow fuse element blank is provided by drilling a hole along a longitudinal direction of an elongate solid fuse element blank to obtain a cavity without piercing the fuse element blank.

- a hollow fuse element blank is provided by producing an elongate hollow body, in particular a tube, which is open at both opposite ends.
- a hollow fuse element blank is provided by producing an elongate hollow body, in particular a tube, which is open at both opposite ends.
- Both ends of the solid shackle are severed and are shaped according to the locking end and filling end end pieces described above. Alternatively, the end pieces are manufactured separately.
- the described threads and cavities are introduced.
- the end piece of the filling end is then arranged on the security element.
- the tail of the closing end is placed on the security element.
- the arrangement of the end piece or end pieces can be mechanically detachably or mechanically non-detachably connected to the security element by screwing, welding or gluing.
- the process steps can also be interchanged with one another, so the shaping step can also take place before the fixing step and/or the introduction step.
- the forming step can also occur after the filling step.
- the stated object is also achieved by a method for producing a lock according to one of the preceding types using a security element according to one of the preceding types with the following method steps: introducing the filling end into a locking device; and storing the filling end by activating a storage mechanism of the closure device.

- the stated object is also achieved by a method for preventing an attempted theft with a lock of the above type, with a pressurized fluid escaping from the interior of the security element as a protective agent when the cavity is opened without permission.
- the fluid is introduced as a protective agent and serves to develop an additional protective effect when escaping, which prevents the attempted theft or makes it very difficult (hindered) in order to protect the object to be secured even better.
- the protective agent comprises suitable gases or liquids containing, for example, malodorous substances, signal colors, irritant substances and/or artificial DNA.
- gases or liquids containing, for example, malodorous substances, signal colors, irritant substances and/or artificial DNA.
- a two-component or a three-component mixture as described above is preferred.
- Such a lock or security element has a number of advantages. On the one hand, it is sufficiently robust to keep the fluid in the cavity when used as intended. This increases the security that the user can use the lock without running the risk of coming into contact with the possibly aggressive protective agent. In addition, the structure and manufacture are much simpler. Elaborate inserts to close off the cavity can be omitted.
- the pressure of the fluid causes the fluid to flow out quickly, for example explosively, which frightens the thief without injuring him.
- the fluid is a protective agent, which develops a protective effect when it exits the cavity and, for example, marks the thief (signal color, artificial DNA) and/or at least hinders it (irritant gas, foul-smelling liquid, smoke).

- the detection signal is preferably sent directly via a digital interface as a message to a mobile phone, a security guard or to the police, stating the location of the break-in.
- the escape of the fluid is detected by means of a pressure sensor and is reported via a digital interface of the pressure sensor.

- the pressure sensor has a battery to send the report via the digital interface.
- the pressure sensor can communicate with a cellular network via its own subscriber identifier.
- the security element according to the invention can be positioned in a conventional (standardized) locking device with just a few manipulations.
- the security element provides a surprise effect that will cause the thief to retreat. Even if a thief has already attempted to steal such a security element, he remains uncertain as to which protection means the currently attacked security element is filled with. Possibly carrying protective clothing or a gas mask are rather conspicuous and, as an additional burden, are a hindrance for every thief.
- the security element has a deterrent effect on the potential thief.
- a connection to other security and notification systems can be established as a result of a pressure drop signal.
- the notification can be sent digitally to the owner, the operator or the user as well as to the security guard or the police.
- FIGS. 1a-b Two different exemplary embodiments of security elements 2 according to the invention are shown in FIGS. 1a-b.
- a security element 2 for a lock 1 is shown, here a U-lock 1 as an example of a bicycle lock.
- a security element 2 for another lock 1 is shown, here a padlock.
- the locking devices 3 are only indicated here and are not part of the securing elements 2 of FIGS. 1a-b. A more detailed description of the locking device 3 is on the 3 referred. The following description applies to both fuse elements 2 of Figures 1a and 1b equally.
- the securing element 2 is a rigid bracket which has a cavity 23 .
- a fluid 4 is introduced into the cavity 23 as a protective agent.
- the fuse element 2 has two ends, a closing end 21 at a first end of the fuse element 2 and a filling end 22 at a second end of the fuse element 2 remote from the first end.
- the closing end 21 is an integral part of the fuse element 2.
- the fuse element 2 has been created from a solid fuse element blank into which the cavity 23 has been introduced (see FIG Figure 4a ).
- a distance 212 between the closing end 21 and the cavity 23 is at least as large as the diameter of the fuse element 2.
- the closing end 21 has a notch. This notch is used to temporarily lock the closing end 21 in a locking device 3 of the lock 1 .
- the notch is located between the closing end 21 and the cavity 23 .
- a distance between the notch and the closing end 21 is at least as large as the diameter of the fuse element 2.
- a distance between the notch and the cavity 23 is at least as large as the diameter of the fuse element 2.
- the closing end 22 can be moved neither in the axial direction of movement 10 nor in the rotary movement 11 when the closing mechanism of the closing device 3 is activated.
- the securing element 3 is anchored in the locking device 3 and no end 21, 22 of the securing element 2 can be removed from the locking device 3.
- the filling end 22 at the second end of the securing element 2 remote from the closing end 21 is also an integral part of the securing element 2.
- the cavity 23 is connected to the filling end 22 through a filling valve at the filling end 22 for introducing the fluid 4 into the cavity 23 completed.
- the filling end 22 has a thread, in particular a threaded insert, for fixing the filling valve to the filling end 22 .
- the filling end 22 is mounted at least temporarily in the locking device 3 of the securing element 2 .
- the filling end 22 can therefore be inhibited or blocked in its axial direction of movement 10 when the bearing mechanism of the closing device 3 is activated, so that the securing element 3 cannot be removed from the closing device 3 .
- the filling end 22 is, for example, an integral part of the fuse element 3.
- the fuse element 2 was created from a solid fuse element blank, in which the valve for closing off the cavity 23 was fixed (see FIG Figure 4b ).
- FIG. 2a-b showed various theft scenarios in which the security element 2 according to the invention in FIGS. 1a-b is destroyed when it is integrated in a lock 1.
- Lock 1 is in Figure 2a a padlock and has a locking device whose locking mechanism is in the Fig. 2a-b is in the "closed" state.
- Figure 2a is a tool 5, bolt cutters here, shown. If an attempt is made to forcibly open the cavity 23 of the security element 2 of the lock 1 using the tool 5, the fluid 4 under pressure will escape explosively as a protective agent. This hinders or even prevents the attempted theft.
- the lock 1 according to Figure 2b is a padlock and has a locking device 3 whose locking mechanism is in the "closed” state and whose storage mechanism is in the "stored” state.
- the cavity 23 is forcibly opened, whereby the fluid 4 under pressure escapes explosively as a protective agent. This hinders or even prevents the attempted theft.
- FIGS. 1a-b and 2a-b show a basic representation of a lock 1 with the security element 2 according to the invention according to FIGS. 1a-b and 2a-b, which is mounted in a locking device 3 but not locked.
- the securing element 2 can be moved in the direction of movement 11, but it can only partially move in the direction of movement 10.
- the closing end 21 is inserted into an opening (not shown) of the closing device 3 and is completely inside the closing device 3.
- the closing end 21 has the notch 211 on.
- the locking mechanism 31 has two states. Shown in 3 is the state "open", because the engageable in the notch 211 bolt of the locking mechanism 31 does not engage in the notch 211.
- the securing element 3 is not prevented from having its closing end 21 removed from an opening in the closing device 3 .
- the lock 1 In the open state of the locking mechanism 31, the lock 1 can be placed on the object since the direction of movement 11 is not blocked and an axial movement 10 is also only partially blocked.
- the locking mechanism 31 has a second state "closed” (not shown in 3 ), in which the direction of movement 11 is blocked and an axial movement 10 is almost completely prevented.
- a lock-specific key 9 is provided for changing the state of the locking mechanism 31 .
- This key 9 causes a movement 32 of the locking mechanism 31 so that, for example, the bolt of the locking mechanism 31 engages in the notch 211 . It is then no longer possible to remove the closing end 21 from the closing device 3 . In this state, the lock 1 secures an object.
- the filling end 22 is inserted into a further opening (not shown) of the closing device 3 and is located completely inside the closing device 3 .
- the filling end 22 has a taper 223 . If the filling end 22 of the fuse element 2 in the Closing device 3 is introduced, it can be stored by means of a storage mechanism 33 of the closing device 3 .
- the bearing mechanism 33 has two states. Shown in 3 the state is "stored", because a bolt of the bearing mechanism 33 engages in the taper 223. This partially inhibits or partially prevents the movement of the securing element 3 in the axial direction 10, a rotary movement 11 of the securing element 2 is still possible.
- 3 is only a basic sketch, because any stops of the bearing mechanism 33, which actually inhibit or prevent the movement of the securing element 3, are not shown. Nevertheless, the securing element 3 is prevented from the filling end 22 being removed from the opening of the closing device 3 in the "stored" state of the storage mechanism 33 .
- the storage mechanism 33 has a second state “not stored” (not shown in Fig 3 ). In the "not stored” state, the securing element 3 is not restricted or blocked in any of the directions of movement 10, 11.
- a tool 8 specific to the lock type is provided for changing the state of the bearing mechanism 33 . Changing the bearing mechanism 33 is preferably only possible when the locking mechanism 31 is in the open state, so that the lock-specific key 9 is also required.
- the tool 8 for example an ironing tool, causes a movement 34 of the bearing mechanism 33 so that, for example, the bolt of the bearing mechanism 33 no longer engages in the taper 223. It is then possible to remove the filling end 22 from the closing device 3 . In this way, the filling end 22 can be removed from the closing device 3 . In this way, the filling end 22 can be used to refill the fuse element 3 .
- the filling end 22 has a valve 221 .
- This valve 221 is a non-return valve which, when the cavity 23 is pressurized, closes the cavity 23 airtight at the filling end 22 .
- a spring under the effect of the pressure in the cavity 23 presses on a ball (not shown), which in turn closes a filling channel 224 at the filling end 22 .
- the valve 221 is a separate component and has an external thread. With this external thread, the valve 221 is fixed in a thread, for example by means of a threaded insert 222, in the filling end 22.

- the shape and the material can be different, for example the profile of the blank can also be triangular, square, star-shaped or etc.
- the material can also be a coating of different materials, for example plastic, carbon, Kevlar, or a combination thereof.
- the materials can be braided.
- the blank 6 has been shortened in a preliminary step to the corresponding length of the security element 3 and the notch at the closing end 21 has already been introduced.
- the shortening and introduction of the notch 211 can also take place at a later point in time in the production process, for example after the drilling step.
- a hole is drilled along a longitudinal direction of the elongate solid fuse element blank 6 to obtain a cavity 23 without piercing the fuse element blank 6 by means of a drilling machine (illustration is not limiting) and a drill.
- the distance 212--already described-- is maintained.
- Figure 4b is a according to the drilling step Figure 4a subsequent fixing step in the method according to the invention for producing a security element 3 according to the invention.
- a thread in the open end of the blank 6 - namely the later filling end 22 of the fuse element 3 - introduced.
- the thread is introduced after the securing element blank 6 has been shortened to the desired length.
- a thread is cut into the open end or a threaded insert is inserted into the open end.
- a valve is now fixed into the threaded open end (filling end 22).
- the valve is preferably screwed into the thread of the filling end 22 by means of its external thread. If necessary, it is additionally welded, glued or soldered.
- Area A of Figure 4b is in Figure 4d shown enlarged.
- Figure 4c a molding step in the method according to the invention for producing a fuse element 3 according to the invention is shown.
- the fuse element blank 6 is brought into the desired final shape. To do this, it is bent, for example, to become a lock shackle.
- the finished fuse element 6 is then obtained in the not yet filled state.
- the step according to Figure 4c can also before the steps referred to Figure 4b take place.
- the securing element 6 is then retained in the not yet filled state after the valve has been fixed in the filling end 22 .

- the thread 222 of the filling end 22 into which the valve 221 is screwed can be seen here.
- the valve 221 is, for example, the check valve already described above.
- FIG 4e a filling step in the method according to the invention for producing a security element 6 according to the invention is shown.
- a container 7 with a fluid 4 is placed at the filling end 22 of the securing element 2 .
- a filling nozzle 71 for example a hollow needle, is stopped at the valve 221 or inserted.
- a filling activation 72 allows the fluid 4 to flow out of the container 7 .
- the pressure from the container 7 causes the valve 221 to open in order to fill the fluid 4 into the cavity 23 of the fuse element 3 .
- the container 7, the filling nozzle 71 and the activation 72 are only shown as examples and are intended in particular to illustrate refilling of an already filled security element 6. This can be done manually by an owner of the lock 1.
- the first filling according to Figure 4e can, however, also be done by machine placement.
- Filling according to Figure 4e can be secured further, for example by screwing the filling connector 72 onto the valve 221 of the filling end 22 . Tilting during filling can thus be prevented and the risk of the fluid 4 escaping is thereby minimized.
- the fluid 4 includes one or more of the following: a tear or irritant gas; a tear or irritant fluid, a foul-smelling fluid, a signal color and/or artificial DNA.
- the tear or irritant fluid includes one or more capsaicinoids, such as capsaicin, dihydrocapsaicin, nonivamide, 2-chlorobenzalmalonitrile, dibenzoxazepine, phenacyl chloride, and/or synpropanethial S-oxide.
- capsaicinoids such as capsaicin, dihydrocapsaicin, nonivamide, 2-chlorobenzalmalonitrile, dibenzoxazepine, phenacyl chloride, and/or synpropanethial S-oxide.

- This is, for example, a securing element 2 for a padlock of any size, in which the filling end is supported and the closing end 21 is locked.
- the integral closing end 21 corresponds, for example, to the explanations of Figures 1 to 4 and enables a stable closure of the cavity without further material-related or structurally-related weak points.
- the filling end 22 has the thread 222 as shown in FIGS Figures 1 to 4 is already described.
- the filling end 22 can be closed with an end piece 226 .
- the end piece 226 has an external thread 2261 in order to be detachably connected to the securing element 2 through the thread 222 of the securing element.
- a previously described taper 223 is arranged between the external thread 2261 and the outermost end of the end piece 226 remote from a connection end with the securing element, in order to enable the securing element 2 to be stored in an in 3 To allow locking device 3 shown as an example. Due to the screw connection, the cavity 23 is fluid-tight in the connected state, see also Figure 7a .
- the filling valve 221 is fixed in the filling end 22 .
- the cavity 23 of the fuse element 2 can have a maximum diameter, since the taper 223 does not limit the cavity 23 in its dimensions.
- the enlargement of the cavity 23 allows the use of thinner-walled hollow body for the fuse element 2 and thus a lower cost of materials.
- no weak point is created in the area of the taper 223 due to the securing elements 2 being too thin, as a result of which an undesired escape of fluid could possibly occur with frequent use.
- a valve adapter 225 is optionally provided in order to fix the filling valve 221 in the filling end 22 .
- the valve adapter 225 has an external thread 2251 in order to be detachably connected to the thread 222 of the filling end 22 .
- the valve adapter 225 also has an internal thread in order to be able to fix the filling valve 221 in place.
- the valve adapter also has a taper 2252 that can be introduced into a recess (not shown) in the end piece 226 .
- the valve adapter 225 makes it possible to use small filling valves 221 for securing elements 2 with larger diameters.
- Figure 5b 1 shows an exemplary embodiment of a securing element 2 according to the invention with a closing end 21 with end piece 214 or 214a and a filling end 22 with end piece 226 in the non-connected state.
- This is also a securing element 2 for a padlock of any size, in which the filling end is supported and the closing end 21 is locked.
- Figure 5b will along with Figure 7a described, in which this embodiment is shown in the filled and connected state.
- the filling end 22 has in contrast to the filling end 22 of Figure 5a a cavity 2262 and an element 2263.
- the effect of cavity 2262 and element 2263 is in Figure 7a good to recognize.
- the fluid 4 is introduced into the cavity 23 with the fluid (for example according to Figure 4e ).
- the end piece 226 is then connected to the securing element 2 .
- the element 2263 for example a bolt or pin or a small plate, opens the fixed filling valve 221 during the connection (or as a result of the connection).
- part of the fluid 4 flows into the cavity 2262.
- the fluid is at the filling limits 24 (according to Figure 7a ) which are very close to the tapers 211 and 223, in the region of the end pieces 226 and 214, 214a.
- the filling limit 24 at the filling end 22 is no longer at the position of the valve 221 but protrudes into the cavity 2262 of the end piece 226 .
- Unauthorized separation of the securing element 2 near the ends 21, 22 also leads to the immediate escape of the fluid and thus the impeding or prevention of theft.
- the end piece 226 is mechanically detached (unscrewed) from the filling end 22 .
- the element 2263 of the end piece 226 no longer acts on the filling valve 221 and--should there still be appropriate pressure in the cavity 23--the filling channel 224 is closed again in a fluid-tight manner by the valve 221. This ensures that no protective agent escapes unintentionally.

Description
Die Erfindung betrifft ein hohles Sicherungselement, beispielsweise ein Bügel. Die Erfindung betrifft weiter ein Schloss, beispielsweise ein Vorhängeschloss oder ein Fahrradschloss, mit dem Sicherungselement und einer Schließeinrichtung. Die Erfindung betrifft zudem ein Verfahren zum Herstellen des Sicherungselements und ein Verfahren zum Herstellen des Schlosses. Die Erfindung betrifft auch und ein Verfahren zum Behindern eines Diebstahlversuchs.The invention relates to a hollow securing element, for example a clip. The invention further relates to a lock, for example a padlock or a bicycle lock, with the security element and a locking device. The invention also relates to a method for manufacturing the security element and a method for manufacturing the lock. The invention also relates to and a method for impeding a theft attempt.
Ein Schloss als Diebstahlsicherung wird in verschiedensten Ausführungen zur Sicherung von Gegenständen, wie Fahrrädern oder anderen beweglichen Gegenständen eingesetzt. Ein Schloss als Vorhängeschloss, so wie es beispielsweise in der
Diese Schlösser haben den Nachteil, dass sie bei leichter Bauweise relativ einfach aufgebrochen werden können oder bei verbesserter Sicherheit vergleichsweise schwer, komplex, teuer und unhandlich sind.These locks have the disadvantage of being relatively easy to break open if they are lightweight, or relatively heavy, complex, expensive and cumbersome if security is improved.
Aus diesem Grund beschreibt die
In der
In der
Alle diese Schlösser werden nur ein einziges Mal befüllt. Um ein schleichendes Entweichen der Schutzmittel zu verhindern, wird ein hoher Aufwand betrieben, insbesondere wird das Befüll-Loch und alle Verbindungen zwischen Rohr und Einsatz dauerversiegelt. Das Rohr wird zudem im Inneren speziell behandelt und Außen mit einem Schutzmantel überzogen. Dies erhöht die Kosten der Herstellung derartiger Schlösser.All of these locks are only filled once. In order to prevent the protective agent from gradually escaping, a great deal of effort is expended. In particular, the filling hole and all connections between the pipe and the insert are permanently sealed. The pipe is also specially treated on the inside and covered with a protective jacket on the outside. This increases the cost of manufacturing such locks.
Das Befüllen erfolgt maschinell und während des Herstell-Prozesses. Der Schlossbügel ist dazu in einer speziellen Vorrichtung fixiert. Nur bei einer derartigen Fixierung kann das Befüllen durch primitive Verbindungen, wie einen Presssitz, erfolgen.The filling takes place automatically and during the manufacturing process. The lock shackle is fixed in a special device for this purpose. Only with such a fixation can the filling be done by primitive connections such as a press fit.
Die verwendeten Schutzmittel sind hochaggressiv und teilweise gefährlich. Daher wird bislang das Nachfüllen des Schutzmittels (Signalmediums oder chemischen Substanz) nicht vorgesehen. Ein Gebrauch des Schlosses über einen langen Zeitraum, beispielweise mehrere Jahre oder Jahrzehnte, führt aber unweigerlich zum Entweichen eines Teils oder des gesamten Drucks des Schutzmittels aus dem Hohlraum. Das Schloss verliert also seine zusätzliche Schutzfunktion oder zumindest die Funktion des plötzlichen Austritts des Schutzmittels. Selbst wenn man das Schloss manuell nachfüllen wollte, gäbe es kein Befüll-Zugang im Rohr.The means of protection used are highly aggressive and sometimes dangerous. Therefore, the refilling of the protective agent (signal medium or chemical substance) has not been provided so far. However, use of the lock over a long period of time, for example several years or decades, inevitably leads to part or all of the pressure of the protective agent escaping from the cavity. So the lock loses its additional protective function or at least the function of the sudden escape of the protective agent. Even if you wanted to refill the lock manually, there would be no refilling access in the tube.
Zudem werden stets beide Enden des Sicherungselements (Bügel) mit dem komplexen und speziellen Einsatz abgeschlossen. Diese Einsätze haben Ausnehmungen für das Schließen, mit sehr wenig Rohrmaterial zwischen Ausnehmung und Hohlraum. Durch häufiges Öffnen/Schließen wird dieses Rohrmaterial weiter verringert, sodass die Gefahr besteht, dass der Hohlraum unbeabsichtigt bei einem Schließvorgang geöffnet wird und so, der Nutzer mit dem Schutzmittel in Berührung kommt.In addition, both ends of the security element (shackle) are always terminated with the complex and special insert. These inserts are recessed for closure, with very little tubing between the recess and cavity. This pipe material is further reduced by frequent opening/closing, so that there is a risk that the cavity will be opened unintentionally during a closing process and the user will come into contact with the protective means.
Die Enden des Sicherungselements (Bügel) sind entweder massiv ausgebildet und/oder sie sind aufgrund der Positionierung der Verschlüsse des Hohlraums vollständig frei vom Schutzmittel. Bei einer Zerstörung des Sicherungselements in einem Bereich nahe eines der Enden würde kein Schutzmittel austreten und das Schloss würde nicht die gewünschte Wirkung (Freisetzen des Schutzmittels) erzielen.The ends of the securing element (clip) are either solid and/or they are completely free of the protective means due to the positioning of the closures of the cavity. If the security element were to be destroyed in an area close to one of the ends, no protective agent would escape and the lock would not achieve the desired effect (release of the protective agent).

Die Aufgabe der hier vorliegenden Erfindung ist es, ein mit einem - unter Druck stehenden - Schutzmittel gefülltes Sicherungselement bereitzustellen, dass einen Diebstahlversuch zuverlässig verhindert oder zumindest ausreichend behindert. Insbesondere soll das Sicherungselement einfach herstellbar sowie schnell und unkompliziert nachfüllbar sein. Beim Füllen und auch im Betrieb soll ein Nutzer stets sicher vor ausweichendem Schutzmittel sein. Der Hohlraum für das Schutzmittel soll maximiert werden, sodass die Materialien für das Sicherungselement nicht mehr die hohen Stabilitätsanforderungen erfüllen müssen und damit kostengünstiger werden können.The object of the present invention is to provide a security element that is filled with a protective agent—which is under pressure—and that reliably prevents or at least adequately hinders an attempted theft. In particular, the security element should be easy to produce and refillable quickly and easily. When filling and also during operation, a user should always be safe from avoiding protective agents. The cavity for the protective means should be maximized so that the materials for the security element no longer have to meet the high stability requirements and can therefore become more cost-effective.
Die Aufgabe wird mit den in den unabhängigen Patentansprüchen beschriebenen technischen Maßnahmen gelöst. Vorteilhafte Ausgestaltungen sind in den jeweils abhängigen Patentansprüchen beschrieben.The task is solved with the technical measures described in the independent patent claims. Advantageous configurations are described in the respective dependent patent claims.
Insbesondere wird die Aufgabe durch ein hohles Sicherungselement gelöst, mit einem Schließ-Ende eingerichtet zum zeitweisen Arretieren in einer Schließeinrichtung in Abhängigkeit eines Schließmechanismus der Schließeinrichtung; einem Befüll-Ende eingerichtet zum zumindest zeitweisen Lagern des Sicherungselements in der Schließeinrichtung; einem zwischen dem Schließ-Ende und dem Befüll-Ende angeordneten Hohlraum in dem ein unter Druck stehendes Fluid als Schutzmittel eingebracht ist, wobei der Hohlraum am Befüll-Ende durch ein Einfüllventil am Befüll-Ende zum Einbringen des Fluids in den Hohlraum abgeschlossen, also zumindest für den Zeitpunkt des Einbringens des Fluids in den Hohlraum abschließbar ist, und wobei das Befüll-Ende einen Gewindeeinsatz zum Fixieren des Einfüllventils am Befüll-Ende aufweist.In particular, the object is achieved by a hollow securing element having a locking end arranged for temporary locking in a locking device in dependence on a locking mechanism of the locking device; a filling end set up for at least temporarily storing the securing element in the locking device; a cavity arranged between the closing end and the filling end, in which a pressurized fluid is introduced as a protective means, the cavity at the filling end being closed off by a filling valve at the filling end for introducing the fluid into the cavity, i.e. at least is lockable at the time the fluid is introduced into the cavity, and wherein the filling end has a threaded insert for fixing the filling valve to the filling end.
Die Aufgabe wird zudem auch durch ein Schloss, bevorzugt ein Vorhängeschloss oder ein Fahrradschloss, gelöst, welches ein Sicherungselement gemäß einem der vorhergehenden Art und eine Schließeinrichtung mit einem Schließmechanismus aufweist, wobei ein Schließ-Ende des Sicherungselements in der Schließeinrichtung in Abhängigkeit des Schließmechanismus der Schließeinrichtung arretierbar ist und wobei ein Befüll-Ende des Sicherungselements in der Schließeinrichtung gelagert ist.The object is also achieved by a lock, preferably a padlock or a bicycle lock, which has a security element according to one of the preceding types and a locking device with a locking mechanism, with a locking end of the security element in the locking device depending on the locking mechanism of the locking device can be locked and wherein a filling end of the securing element is mounted in the locking device.
Die für das erfindungsgemäße Sicherungselement möglichen Schloss-Bauarten sind vielfältig, beispielsweise kann ein Vorhängeschloss, ein Bremsscheibenschloss, ein Fahrradschloss, ein Bolzenschloss, ein Rundbügelschloss, ein Faltschloss, etc. mit dem erfindungsgemäßen Sicherungselement ausgestattet werden.The types of lock possible for the security element according to the invention are diverse, for example a padlock, a brake disc lock, a bicycle lock, a bolt lock, a round shackle lock, a folding lock, etc. can be equipped with the security element according to the invention.
Das Sicherungselement ist hohl und insbesondere ein hohler Bügel oder ein hohler Schlauch.The securing element is hollow and in particular a hollow bracket or a hollow tube.
Das Sicherungselement hat ein Schließ-Ende, das zum zeitweisen Arretieren in eine Schließeinrichtung in Abhängigkeit eines Schließmechanismus der Schließeinrichtung eingerichtet ist. Der Schließmechanismus umfasst zumindest zwei Zustände: "Offen" und "Geschlossen". Ein Wechsel der Zustände wird beispielsweise durch einen entfernbaren schlossspezifischen Schlüssel oder das Einstellen einer korrekten Zahlenkombination oder einem passenden biometrischen Merkmal ermöglicht. Das Arretieren des Schließ-Endes in der Schließeinrichtung bewirkt, dass das Sicherungselement in der Schließeinrichtung festgehalten wird bis ein erneuter Wechsel des Zustands des Schließmechanismus in den Zustand "Offen" erfolgt.The securing element has a locking end which is adapted to be temporarily locked into a locking device in response to a locking mechanism of the locking device. The locking mechanism includes at least two states: "open" and "closed". A change of status is made possible, for example, by a removable lock-specific key or by setting a correct combination of numbers or a suitable biometric feature. Locking the locking end in the locking device causes the securing element to be held in place in the locking device until the status of the locking mechanism changes again to the “open” status.
Die Schließeinrichtung beinhaltet den Schließmechanismus. Der Zustand des Schließmechanismus kann durch einen schlossspezifischen Schlüssel, eine Zahlenkombination, durch federbelastete Magnete, Funksignale, Elektromechanik, motorischen Antrieb etc. gewechselt werden.The locking device includes the locking mechanism. The status of the locking mechanism can be changed using a lock-specific key, a combination of numbers, spring-loaded magnets, radio signals, electromechanics, a motor drive, etc.
Das Sicherungselement hat zudem ein Befüll-Ende, das zum zumindest zeitweisen Lagern des Sicherungselements in der Schließeinrichtung eingerichtet ist. Ein mechanisches Lagern wird allgemein als ein Reduzieren von Bewegungsfreiheitsgraden definiert. Lagern kann bevorzugt auch ein Arretieren umfassen. Erfindungsgemäß ist ein Lagermechanismus in der Schließeinrichtung dazu eingerichtet, das Befüll-Ende in der Schließeinrichtung zu lagern. Das Befüll-Ende wird beispielsweise an einer axialen Bewegung gehindert oder die axiale Bewegung wird nur für einen vordefinierten Weg zugelassen. Durch das Lagern wird das Sicherungselement insbesondere daran gehindert, aus der Schließeinrichtung entnommen (entfernt) zu werden. Bevorzugt, wird ein Drehen (Rotieren) des Sicherungselements innerhalb der Schließeinrichtung durch das Lagern in der Schließeinrichtung nicht unterbunden. Das Lagern des Befüll-Endes in der Schließeinrichtung schützt das Befüll-Ende vor Umwelteinflüssen und ungewollten Entlüften des Hohlraums des Sicherungselements.The securing element also has a filling end which is set up for at least temporarily storing the securing element in the locking device. Mechanical restraint is generally defined as reducing degrees of freedom of movement. Storage can preferably also include locking. According to the invention, a storage mechanism in the closing device is set up to store the filling end in the closing device. The end of filling is prevented from moving axially, for example, or the axial movement is only permitted for a predefined path. As a result of the storage, the securing element is in particular prevented from being removed (removed) from the locking device. Preferably, turning (rotating) of the securing element within the locking device is not prevented by being stored in the locking device. Storing the filling end in the closing device protects the filling end from environmental influences and unwanted venting of the cavity of the fuse element.
Das Lagern erfolgt beispielsweise permanent. Damit kann ein Lagermechanismus innerhalb der Schließeinrichtung nur einen Zustand (Lagernd) umfassen. Nach einer Montage des Sicherungselements kann dieses dauerhaft nicht aus der Schließeinrichtung entfernt werden, ohne dass das Schließeinrichtung zerstört wird. Ein derartiger Mechanismus ist beispielsweise durch einmaliges Einklicken des Sicherungselements in eine entsprechende Halterung in der Schließeinrichtung ermöglicht.Storage is permanent, for example. A storage mechanism within the locking device can therefore only have one state (in stock). After the security element has been installed, it cannot be permanently removed from the locking device without the locking device being destroyed. Such a mechanism is made possible, for example, by clicking the securing element once into a corresponding holder in the locking device.
Das Lagern erfolgt beispielsweise zeitweise. Damit kann ein Lagermechanismus innerhalb der Schließeinrichtung zwei Zustände, nämlich "Lagernd" und "nicht-lagernd", umfassen. Ein Wechsel der Zustände wird beispielsweise durch ein schlosstypspezifisches Werkzeug durchgeführt. Das Werkzeug ist insbesondere schlossunspezifisch, beispielsweise ein Bügelwerkzeug.Storage is, for example, temporary. Thus, a storage mechanism within the locking device can have two states, namely "stocked" and "not stocked". A change of states is carried out, for example, by a lock-type-specific tool. In particular, the tool is not specific to a lock, for example an ironing tool.
Ist der Lagermechanismus "lagernd" eingestellt, so kann das Sicherungselement nicht aus der Schließeinrichtung entnommen werden. In diesem Zustand befindet sich das Befüll-Ende im Inneren der Schließeinrichtung und ist nicht frei zugänglich. Das Befüll-Ende ist somit im "lagern" Zustand vor Umwelteinflüssen zusätzlich geschützt und ein Austreten von Fluid aus dem Sicherungselement ist verhindert.If the storage mechanism is set to "storage", the securing element cannot be removed from the locking device. In this state, the filling end is inside the closing device and is not freely accessible. The filling end is thus additionally protected from environmental influences in the "stored" state and fluid is prevented from escaping from the securing element.
Ist der Lagermechanismus "nicht-lagernd" eingestellt, so kann das Sicherungselement aus der Schließeinrichtung entnommen werden. Auf diese Weise wird das Befüll-Ende des Sicherungselements frei zugänglich. Somit kann das Sicherungselement am Befüll-Ende befüllt/nachgefüllt werden. Dieses Füllen kann in festgelegten Zeitabständen oder nach einer Reparatur des Sicherungselements erfolgen.If the storage mechanism is set to "non-storage", the securing element can be removed from the locking device. In this way, the filling end of the fuse element is freely accessible. The security element can thus be filled/refilled at the end of the filling process. This filling can take place at fixed time intervals or after the fuse element has been repaired.
Die Schließeinrichtung kann konventioneller Art sein und ist beispielsweise eine abgeschlossene Baugruppe. Das Sicherungselement kann standardisiert geformt sein, um möglichst einfach in eine konventionelle Schließeinrichtung positioniert zu werden. Der Einbau des Sicherungselements kann ohne großen Aufwand erfolgen, da es eine eigene abgeschlossene Baugruppe ist.The locking device can be of a conventional type and is, for example, a self-contained assembly. The securing element can have a standardized shape in order to be positioned in a conventional locking device as simply as possible. The installation of the security element can be done without great effort, since it is a separate self-contained assembly.
Zudem umfasst das Sicherungselement einen zwischen dem Schließ-Ende und dem Befüll-Ende angeordneten Hohlraum in dem ein unter Druck stehendes Fluid als Schutzmittel eingebracht ist. Der Hohlraum ist abgeschlossen. Somit kann das im Hohlraum befindliche und unter Druck stehende Fluid nicht nach außen dringen. Beispielsweise ist er luftdicht oder fluiddicht abgeschlossen. Wird der Hohlraum gewaltsam geöffnet, wird das Fluid freigesetzt. So tritt das unter Druck stehende Fluid sofort und schnell, insbesondere explosionsartig, aus.In addition, the securing element comprises a cavity arranged between the closing end and the filling end, in which a pressurized fluid is introduced as a protective means. The cavity is closed. Thus, the fluid located in the cavity and under pressure cannot escape to the outside. For example, it is airtight or fluid-tight. If the cavity is opened by force, the fluid is released. The pressurized fluid escapes immediately and quickly, particularly explosively.
Der Hohlraum endet vor dem Schließ-Ende im Inneren des Sicherungselements. Es wird dadurch ein permanentes Verschließen des Schließ-Ende gesorgt, auf etwaige Schlusskappen oder Einsätze kann verzichtet werden.The cavity ends in front of the closing end inside the fuse element. This ensures that the closing end is permanently closed, and any end caps or inserts can be dispensed with.
Ein Fluid ist hierbei eine Flüssigkeit oder ein Gas. Ein unter Druck stehendes Fluid ist ein Fluid welches mit gegenüber dem Normaldruck, also dem Atmosphärendruck (1 bar) wesentlich erhöhten Druck, also beispielsweise 2bar, bevorzugt 5 bar, mehr bevorzugt 12 bar, in den Hohlraum des Sicherungselements eingebracht wurde. Das Fluid weist im Inneren des Hohlraums bevorzugt einen Druck zwischen 3bar und 8bar auf, um ein wirkungsvolles Ausströmen zu gewährleisten. Diese untere Grenze von 3 bar ermöglicht ein zuverlässiges Austreten beim unerlaubten Öffnen des Hohlraums, beispielsweise beim Verletzen des Sicherheitselements durch mechanische Krafteinwirkung. Diese obere Grenze von 8 bar ermöglicht die Einhaltung von Sicherheitsbestimmungen (kein ungewolltes Austreten) während des Be- und/oder Nachfüllens und verringert die Material- und Dichtheitsanforderungen an das Sicherheitselement. Im Hohlraum verbleibt das Fluid bestimmungsgemäß ohne wesentlichen Druckverlust, es sei denn, der Hohlraum wird wieder geöffnet. Beim unbefugten Öffnen des Hohlraums, beispielsweise einem Verletzen der Außenhülle (Durchtrennen, Durchschneiden, Durchknipsen, Aufsägen) des Sicherungselements während eines Diebstahlversuchs, tritt das Fluid schnell und zuverlässig, beispielsweise explosionsartig, heraus, wodurch die unmittelbare Umgebung und der Dieb mit dem Fluid, also dem Schutzmittel, benetzt werden.A fluid is a liquid or a gas. A pressurized fluid is a fluid which has been introduced into the cavity of the fuse element at a pressure which is significantly higher than normal pressure, ie atmospheric pressure (1 bar), ie for example 2 bar, preferably 5 bar, more preferably 12 bar. Inside the cavity, the fluid preferably has a pressure of between 3 bar and 8 bar in order to ensure effective outflow. This lower limit of 3 bar enables a reliable escape if the cavity is opened without permission, for example if the security element is damaged by mechanical force. This upper limit of 8 bar makes it possible to comply with safety regulations (no unwanted leakage) during filling and/or refilling and reduces the material and tightness requirements for the safety element. The fluid remains in the cavity as intended without any significant loss of pressure, unless the cavity is opened again. If the cavity is opened without authorization, for example if the outer shell is damaged (severing, cutting through, clipping, sawing open) of the security element during an attempted theft, the fluid escapes quickly and reliably, for example explosively, leaving the immediate environment and the thief with the fluid, i.e the protective agent, are wetted.
Zwischen dem Schließ-Ende und dem Hohlraum ist bevorzugt ein ausreichender Abstand vorgesehen. In diesem Abstand besteht das Sicherungselement aus massivem Material ohne Hohlraum. Der ausreichende Abstand ist beispielsweise mindestens so groß, wie der Durchmesser des Sicherungselements. Auf diese Weise ist ein ausreichend stabiles Schließ-Ende erhalten, welches auch nach einer Vielzahl von Schließvorgängen - in denen das Sicherungselement in eine entsprechende Öffnung der Schließeinrichtung eingeführt wird - einen stabil abgeschlossenen Hohlraum aufweist.A sufficient distance is preferably provided between the closing end and the cavity. At this distance, the fuse element consists of solid material without a cavity. The sufficient distance is, for example, at least as large as the diameter of the security element. In this way, a sufficiently stable locking end is obtained, which has a stably sealed cavity even after a large number of locking processes—in which the securing element is inserted into a corresponding opening of the locking device.
Der Hohlraum ist am Befüll-Ende durch ein Einfüllventil zum Einbringen des Fluids in den Hohlraum abgeschlossen, also zumindest für den Zeitpunkt des Einbringens des Fluids in den Hohlraum (Das Be- bzw. Nachfüllen) abschließbar. Das Einfüllventil ist am Befüll-Ende angeordnet und dient dazu, ein Befüll-Loch im Inneren des Befüll-Endes durch den Druck im Inneren des Hohlraums zumindest für den Zeitraum des Einbringens des Fluids oder auch dauerhaft bis zum nächsten Einbringen des Fluids zu schließen. Das Befüll-Ventil ist beispielsweise ein Rückschlagventil, insbesondere ein Kugelrückschlagventil oder ein Tellerrückschlagventil. Derartige Ventile sind in der gesperrten Richtung hermetisch dicht. Das Kugelrückschlagventil besteht aus einer Verengung, die durch eine Kugel verschlossen wird. Die Kugel wird durch eine Feder auf die Verengung gedrückt und verschließt so den Durchgang. Das Fluid kann somit im verschlossenen Zustand nicht aus dem Hohlraum durch das Befüll-Ende Bei einem Tellerrückschlagventil sorgt eine Feder für die Sperrung des Ventils. Der Dichtkörper ist in Form einer flachen Platte oder eines Tellers ausgeführt. Zur Führung wird ein Bolzen oder Stift verwendet.The cavity is closed off at the filling end by a filling valve for introducing the fluid into the cavity, ie it can be closed off at least for the time when the fluid is introduced into the cavity (filling or refilling). The filling valve is arranged at the filling end and serves to close a filling hole inside the filling end by the pressure inside the cavity at least for the period of time the fluid is being introduced or also permanently until the next time the fluid is introduced. The filling valve is, for example, a check valve, in particular a ball check valve or a disk check valve. Such valves are hermetically sealed in the blocked direction. The ball check valve consists of a constriction that is closed by a ball. The ball is raised by a spring the constriction is pressed and thus closes the passage. The fluid can therefore not get out of the cavity through the filling end when it is closed. In the case of a non-return valve, a spring ensures that the valve is blocked. The sealing body is designed in the form of a flat plate or dish. A bolt or pin is used for guidance.
Das Befüll-Ende des Sicherungselements weist ein Gewinde, beispielsweise einen Gewindeeinsatz, zum Fixieren des Einfüllventils am Befüll-Ende auf. Das Ventil ist bevorzugt kein integraler Bestandteil des Sicherungselementes oder des Befüll-Endes, sondern ein eigenes Bauteil. Das Ventil kann deshalb ein eigenes Gehäuse aufweisen. Das Ventil wird mit dem Sicherungselement während der Herstellung verbunden (fixiert). Das Fixieren erfolgt bevorzugt dauerhaft. Beispielsweise mittels Klebe- und/oder Schweißverbindung kann auch eine zusätzliche nicht-lösbare Verbindung zwischen Befüll-Ende und Ventil hergestellt werden. Durch das Verwenden von derartigen Ventilen kann das Befüll-Ende wesentlich weniger komplex ausgestaltet werden. Lediglich ein Gewinde ist vorzusehen, in das das Ventil eingeschraubt wird. Dazu weist das Ventil ein zum Gewinde des Befüll-Endes entsprechendes Außengewinde, beispielsweise an seinem Gehäuse, auf.The filling end of the securing element has a thread, for example a threaded insert, for fixing the filling valve on the filling end. The valve is preferably not an integral part of the securing element or the filling end, but rather a separate component. The valve can therefore have its own housing. The valve is connected (fixed) to the fuse element during manufacture. The fixing is preferably permanent. An additional, non-detachable connection between the filling end and the valve can also be produced, for example, by means of an adhesive and/or welded connection. By using such valves, the filling end can be made significantly less complex. Only a thread is to be provided into which the valve is screwed. For this purpose, the valve has an external thread corresponding to the thread of the filling end, for example on its housing.
Bei einem Befüll- oder Nachfüll-Vorgang wird beispielsweise ein Fluid unter Druck gegen das Ventil und damit beispielsweise gegen die Kugel oder den Teller gedrückt. Überwiegt die durch den Druck ausgeübte Kraft des Fluids der Kraft der Feder im Ventil, so strömt das Fluid durch das Befüll-Loch des Befüll-Endes in den Hohlraum des Sicherungselements. Bei einem Befüll- oder Nachfüll-Vorgang wird beispielsweise eine Hohlnadel eines Behälters auf das Ventil platziert oder ein Element (Mechanismus) öffnet das Ventil. Der Behälter beinhaltet das Fluid. Mittels eines Treibmittels oder durch ein Beaufschlagen des Fluids mit Druck strömt das Fluid aus dem Behälter bei Betätigung durch die Hohlnadel oder aufgrund des Elements (Mechanismus) in Richtung des Ventils.During a filling or refilling process, for example, a fluid under pressure is pressed against the valve and thus, for example, against the ball or the plate. If the force of the fluid exerted by the pressure exceeds the force of the spring in the valve, the fluid flows through the filling hole of the filling end into the cavity of the securing element. During a filling or refilling process, for example, a hollow needle of a container is placed on the valve or an element (mechanism) opens the valve. The container holds the fluid. By means of a propellant or by pressurizing the fluid, the fluid flows out of the container in the direction of the valve when actuated by the hollow needle or due to the element (mechanism).
Durch das erfindungsgemäße Sicherungselement wird ein Nachfüllen des Hohlraums ermöglicht. Durch Lagerung des Befüll-Endes innerhalb der Schließeinrichtung wird das Befüll-Ende vor Umwelteinflüssen geschützt und ein Austreten des Fluids bei bestimmungsgemäßer Verwendung des Sicherungselements (Öffnen/Schließen zur Sicherung von beweglichen Gegenständen oder einfachen Verschlüssen) verhindert. Das Schließ-Ende ist derart ausgestaltet, dass auch bei häufigem Öffnen/Schließen keine Gefahr besteht, dass der Hohlraum unbeabsichtigt bei einem Schließvorgang geöffnet wird. Die Ausgestaltungen von Schließ-Ende und Befüll-Ende sorgen also dafür, dass der Nutzer nicht in ungewollter Weise mit der Substanz in Berührung kommt.A refilling of the cavity is made possible by the securing element according to the invention. By storing the filling end within the closure device, the filling end is protected from environmental influences and the fluid is prevented from escaping when the security element is used as intended (opening/closing to secure movable objects or simple closures). The closing end is designed in such a way that even with frequent opening/closing there is no risk of the cavity being unintentionally opened during a closing process. The configurations of the closing end and the filling end therefore ensure that the user does not come into contact with the substance in an unintentional manner.
In einer bevorzugten Ausgestaltung ist das Schließ-Ende und/oder das Befüll-Ende ein integraler Bestandteil des Sicherungselements. Es besteht damit aus dem gleichen Material, wie das Sicherungselement und muss nicht extra mit dem Sicherungselement verbunden werden. Damit wird eine zusätzliche Verbindung eingespart und eine Schwachstelle im Sicherungselement beseitigt, was aufgrund des unter Druck stehenden Hohlraums nicht zu vernachlässigen ist. Die Stabilität des Sicherungselements ist erhöht und die Komplexität verringert, wodurch Kosten bei der Herstellung eingespart werden können.In a preferred embodiment, the closing end and/or the filling end is an integral part of the securing element. It therefore consists of the same material as the securing element and does not have to be connected to the safety element separately. This saves an additional connection and eliminates a weak point in the fuse element, which is not negligible due to the pressurized cavity. The stability of the security element is increased and the complexity is reduced, as a result of which production costs can be saved.
In einer bevorzugten Ausgestaltung weist das Schließ-Ende eine Einkerbung auf, in die der Schließmechanismus der Schließeinrichtung zum zeitweisen Arretieren in die Schließeinrichtung in Abhängigkeit des Schließmechanismus der Schließeinrichtung eingreifen kann. Die Einkerbung ist bevorzugt in einem Bereich des Sicherungselements, in dem der Hohlraum nicht angeordnet ist. Bevorzugt ist der Abstand von der Einkerbung zum Hohlraum mindestens so groß, wie der Querschnitt des Sicherungselements. Auf diese Weise beeinträchtigt der Schließmechanismus nicht die Sicherheit, dass das Fluid aus dem Hohlraum durch hohe Beanspruchung des Sicherungselementes in unerwünschter Weise austreten kann.In a preferred embodiment, the closing end has a notch into which the locking mechanism of the locking device can engage for temporary locking in the locking device depending on the locking mechanism of the locking device. The notch is preferably in an area of the fuse element in which the cavity is not arranged. The distance from the notch to the cavity is preferably at least as large as the cross section of the fuse element. In this way, the locking mechanism does not impair the security that the fluid can escape from the cavity in an undesired manner due to high stress on the securing element.
In einer bevorzugten Ausgestaltung weist das Befüll-Ende eine Einkerbung oder Verjüngung auf, in die ein Lager-Mechanismus der Schließeinrichtung zum Lagern des Sicherungselements in der Schließeinrichtung eingreifen kann. Dies ermöglicht eine einfache und unkomplizierte Möglichkeit der mechanischen Lagerung.In a preferred embodiment, the filling end has a notch or taper, into which a bearing mechanism of the locking device can engage for supporting the securing element in the locking device. This enables a simple and uncomplicated option for mechanical storage.
Das Schutzmittel weist bevorzugt eines der folgenden Mittel auf Rauchgas; Tränen- oder Reizgas; Tränen- oder Reizflüssigkeit; Ammoniak mit Schwefel; Eisensulfid mit Salzsäure; Buttersäure; Signalfarbe; und/oder künstliche DNA.The protection means preferably comprises one of the following means: flue gas; tear gas or tear gas; tear or irritant fluid; ammonia with sulfur; iron sulfide with hydrochloric acid; butyric acid; signal color; and/or artificial DNA.
Das Schutzmittel weist bevorzugt ein Treibmittel auf, um in den Hohlraum eingebracht werden zu können. Das Treibmittel ist erfindungsgemäß ein nicht-brennbares Treibmittel, beispielsweise Kohlendioxid. Damit wird ein Treibmittel verwendet, bei dem keine Explosionsgefahr beim unerlaubten Auftrennen des Sicherungselements, beispielsweise durch Funkenflug bei Verwendung eines akkubetriebenem Trennschleifer, besteht.The protective means preferably has a propellant in order to be able to be introduced into the cavity. According to the invention, the propellant is a non-combustible propellant, for example carbon dioxide. A propellant is thus used in which there is no risk of explosion if the security element is cut open without permission, for example as a result of flying sparks when using a battery-operated cut-off grinder.
In einer ersten Ausgestaltung ist das Fluid ein Gemisch aus drei der folgenden Komponenten.In a first embodiment, the fluid is a mixture of three of the following components.
Eine erste Komponente ist ein nicht gefährdender langanhaltenden Farbstoff (Signalfarbe, Tinte) zum Markieren eines Täters, dessen Werkzeug und des potenziellen Diebesguts über einen längeren Zeitraum. Eine zweite Komponente ist eine künstliche DNA, um den markierten Täter zweifelsfrei der begangenen Tat überführen zu können. Eine dritte Komponente ist eine nicht gefährdende übelriechende Flüssigkeit, beispielsweise eine natürliche Flüssigkeit oder eine Flüssigkeit aus dem Lebensmittelbereich, wodurch der Täter gezwungen wird, den Tatort als unangenehm riechenden Ort zu verlassen.A first component is a non-hazardous long-lasting dye (signal color, ink) to mark a perpetrator, his tools and the potential stolen goods over a longer period of time. A second component is an artificial DNA in order to be able to convict the marked offender of the crime committed without any doubt. A third component is a non-hazardous malodorous liquid, such as a natural or food-grade liquid, which forces the perpetrator to leave the crime scene as an unpleasant-smelling place.
In einer zweiten, kostengünstigen, Ausgestaltung ist das Fluid ein Gemisch aus der genannten ersten Komponente mit der dritten Komponente.In a second, cost-effective embodiment, the fluid is a mixture of the first component mentioned with the third component.
Ziel bei der Wahl eines geeigneten Schutzmittels ist es stets, den Dieb (Täter) am Diebstahlversuch zu hindern, ihn dabei aber nicht zu verletzen. Aus diesen Gründen wird der o.g. Druckbereich gewählt und deshalb sind die hier beschriebenen Komponenten vorteilhaft.The aim when choosing a suitable means of protection is always to prevent the thief (perpetrator) from attempting theft, but not to injure him in the process. For these reasons, the above pressure range is chosen and therefore the components described here are advantageous.
Bevorzugt ist das Sicherungselement ein starrer Bügel aus Metall. Damit ist ein massives Sicherungselement geschaffen, bei dem der Hohlraum garantiert abgeschlossen bleibt und erst bei Beschädigung oder Zerstörung des Sicherungselements das Fluid austritt.The securing element is preferably a rigid bracket made of metal. This creates a solid fuse element in which the cavity is guaranteed to remain closed and the fluid only escapes if the fuse element is damaged or destroyed.
Bevorzugt ist das Sicherungselement ein flexibler Schlauch, der beispielsweise mit einem Geflecht ummantelt ist oder aus einem Geflecht besteht. Dieses Geflecht ist bevorzugt aus einem robusten Material, beispielsweise Metall, Kunststoff, Kevlar oder Karbon.The securing element is preferably a flexible hose which, for example, is covered with a braid or consists of a braid. This mesh is preferably made of a robust material such as metal, plastic, Kevlar or carbon.
Durch die Verwendung eines im Hohlraum des Sicherheitselements eingebrachten Schutzmittel ermöglicht es, auf kostengünstigere Materialien als Sicherheitselement zurückzugreifen. Bei den verwendeten Materialien können neben Metall und Kunststoff auch Glas, Holz oder auch der Zeit endsprechende geeignete Materialien, zum Einsatz kommen. Auf speziell gehärtete Materialen, wie Stahl etc., kann beispielsweise komplett verzichtet werden, denn der Dieb wird nicht durch widerstandsfähige Materialien, sondern durch das austretende Schutzmittel vom Diebstahl abgehalten.The use of a protective means introduced in the cavity of the security element makes it possible to use less expensive materials as the security element. In addition to metal and plastic, the materials used can also be glass, wood or other suitable materials of the time. Specially hardened materials, such as steel, etc., can be completely dispensed with, for example, because the thief is not deterred from theft by resistant materials, but by the escaping protective agent.
In einer bevorzugten Ausgestaltung ist am Befüll-Ende ein Endstück lösbar verbunden mit dem Sicherungselement zum Verschließen des Hohlraums angeordnet. Als Endstück kann ein massives, ein-stückiges Element dienen, beispielsweise ein Pfropf, ein Stöpsel oder entsprechend ähnlicher Verschluss. Das Endstück verschließt dabei das hohle Sicherungselement und verhindert so das Entweichen des Fluids.In a preferred embodiment, an end piece is arranged at the filling end in a detachably connected manner with the safety element for closing the cavity. A solid, one-piece element can serve as the end piece, for example a stopper, a stopper or a correspondingly similar closure. The end piece closes the hollow securing element and thus prevents the fluid from escaping.
Das Endstück des Befüll-Endes ist bevorzugt lösbar unter Verwendung des Gewindes des Befüll-Endes mit dem Sicherungselement verbunden. Dabei ist das Gewinde des Befüll-Endes in einer Doppelfunktion einerseits für das Fixieren des Gewindes und andererseits für das Verschließen des Sicherungselements durch das Endstück vorgesehen. Das Gewinde weist dazu eine Länge auf, die in etwa mindestens der Summe der Länge eines Außengewindes des Befüll-Ventils und der Länge eines Außengewindes des Endstücks für das Befüll-Ende entspricht.The end piece of the inflation end is preferably detachably connected to the securing element using the thread of the inflation end. The thread of the filling end is provided with a dual function on the one hand for fixing the thread and on the other hand for closing the securing element by the end piece. For this purpose, the thread has a length which corresponds approximately to at least the sum of the length of an external thread of the filling valve and the length of an external thread of the end piece for the filling end.
Bevorzugt ist zwischen dem äußersten Ende des Endstücks des Befüll-Endes und dem Außengewinde die oben genannte Verjüngung oder Einkerbung zur Arretierung des Sicherungselements in einem Schließmechanismus angeordnet.The above-mentioned taper or notch for locking the securing element in a locking mechanism is preferably arranged between the outermost end of the end piece of the filling end and the external thread.
In einer bevorzugten Ausgestaltung weist das Endstück des Befüll-Endes eine Kavität auf, die ein Teil des Hohlraums des Sicherheitselements ist, wenn das Endstück mit dem Sicherheitselement verbunden ist. Auf diese Weise setzt sich der Hohlraum bis an sein äußerstes Ende fort und ein Auftrennen der Außenhülle des Sicherungselements im Bereich des Befüll-Endes führt ebenfalls zum sofortigen Austreten des Fluids.In a preferred embodiment, the end piece of the filling end has a cavity which is part of the cavity of the security element when the end piece is connected to the security element. In this way, the hollow space continues to its outermost end, and separating the outer shell of the securing element in the region of the filling end also leads to the fluid escaping immediately.
Bevorzugt ist dazu ein Element am Endstücks vorgesehen, das das Einfüllventil zum Einbringen des Fluids in die Kavität des Endstücks öffnet. Das Element ist beispielsweise ein mechanischer Stift oder Bolzen, der das Ventil beim Anordnen des Endstücks am Befüll-Ende öffnet. Durch das Element wird der Befüll-Kanal wieder geöffnet und verbleibt offen, bis das Endstück wieder vom Sicherungselement entfernt ist. Der geöffnete Befüll-Kanal ermöglicht das Zurückströmen eines geringen Teils des Fluids in die Kavität des Endstücks.For this purpose, an element is preferably provided on the end piece, which element opens the filling valve for introducing the fluid into the cavity of the end piece. The element is, for example, a mechanical pin or bolt that opens the valve when the end piece is placed at the filling end. The filling channel is opened again by the element and remains open until the end piece is removed from the securing element again. The opened filling channel allows a small part of the fluid to flow back into the cavity of the end piece.
Bevorzugt verläuft die Kavität bis zu der oben genannte Verjüngung oder Einkerbung zum oben beschriebenen zumindest zeitweisen Lagern des Sicherungselements in der Schließeinrichtung eingerichtet.The cavity preferably runs up to the above-mentioned taper or indentation, designed for the above-described at least temporary storage of the securing element in the locking device.
Damit der Hohlraum im Sicherungselement einen möglichst großen Durchmesser haben kann, aber die zum zumindest zeitweisen Lagern des Sicherungselements in der Schließeinrichtung benötigten Verjüngung bzw. Einkerbung am Sicherheitselement diesen Hohlraum nicht unnötig begrenzen bzw. in dem Bereich der Verjüngung bzw. Einkerbung das Sicherheitselement aufgrund des Hohlraums nicht zu dünnwandig wird, ist insbesondere bei sehr kleinen Schlossbügeln, beispielsweise Vorhängeschlössern, die Verwendung des Endstücks vorteilhaft, um auch für diese kleinen Schlossbügel einen großen Hohlraum zu schaffen.So that the cavity in the security element can have the largest possible diameter, but the taper or notch on the security element required for at least temporarily storing the security element in the locking device does not unnecessarily limit this cavity or in the area of the taper or notch the security element due to the cavity is not too thin-walled, the use of the end piece is particularly advantageous for very small lock shackles, for example padlocks, in order to create a large cavity for these small lock shackles as well.
In einer bevorzugten Ausgestaltung ist am Befüll-Ende ein Ventil-Adapter angeordnet. Dieser Ventil-Adapter weist ein Außengewinde auf, mit dem es an dem Gewinde des Befüll-Endes lösbar fixiert werden kann. Der Ventil-Adapter weist bevorzugt zudem ein Innengewinde zum Fixieren des Einfüllventils im Ventil-Adapter. Der Ventil-Adapter wird bevorzugt verwendet, um ein Standard-Ventil trotz verschiedener Baugrößen von Sicherungselementen, insbesondere unterschiedliche Durchmesser, verwenden zu können. Dies erhöht die Flexibilität bei der Herstellung von Sicherungselementen unterschiedlicher Bauformen und Größen.In a preferred embodiment, a valve adapter is arranged at the filling end. This valve adapter has an external thread with which it can be detachably fixed to the thread of the filling end. The valve adapter preferably also has an internal thread for fixing the filling valve in the valve adapter. The valve adapter is preferably used in order to be able to use a standard valve despite different sizes of securing elements, in particular different diameters. This increases the flexibility in the production of fuse elements of different designs and sizes.
Wird der Ventil-Adapter in Kombination mit einem Endstück am Befüll-Ende verwendet, dann kann der Ventil-Adapter zudem eine Verjüngung aufweisen, wodurch der Ventil-Adapter zumindest Teilweise in eine Kavität des Endstücks eingreifen kann. dazu kann an der Außenseite der Verjüngung ein Gewinde vorgesehen sein, dass in ein Innengewinde des Endstücks eingreifen kann. Dies ermöglicht einen kompakten Aufbau und einen stabilen Verschluss des Sicherungselements.If the valve adapter is used in combination with an end piece at the filling end, the valve adapter can also have a taper, as a result of which the valve adapter can at least partially engage in a cavity of the end piece. for this purpose, a thread can be provided on the outside of the taper that can engage in an internal thread of the end piece. This enables a compact structure and a stable closure of the security element.
Am Schließ-Ende ist ein Endstück verbunden mit dem Sicherungselement zum Verschließen des Hohlraums angeordnet. Als Endstück kann ein massives, ein-stückiges Element dienen, beispielsweise ein Pfropf, ein Stöpsel oder entsprechend ähnlicher Verschluss. Das Endstück verschließt dabei das hohle Sicherungselement am Schließ-Ende und verhindert so das Entweichen des Fluids.An end piece connected to the securing element for closing the cavity is arranged at the closing end. A solid, one-piece element can serve as the end piece, for example a stopper, a stopper or a correspondingly similar closure. The end piece closes the hollow safety element at the closing end and thus prevents the fluid from escaping.
Das Endstück des Schließ-Endes ist in einer Ausgestaltung nicht-lösbar mit dem Sicherungselement verbunden, beispielsweise mittels eines Fügeverfahrens (Schweißen) dauerhaft verbunden. Zusätzlich oder alternativ kann auch ein Klebeverfahren zum dauerhaften Verbinden von Sicherungselement und Endstück des Schließ-Endes verwendet werden.In one embodiment, the end piece of the closing end is non-releasably connected to the securing element, for example permanently connected by means of a joining process (welding). In addition or as an alternative, an adhesive method can also be used to permanently connect the security element and the end piece of the locking end.
Bevorzugt ist zwischen dem äußersten Ende des Endstücks des Schließ-Endes und dem Außengewinde die oben genannte Verjüngung oder Einkerbung zum oben beschriebenen zeitweisen Arretieren in eine Schließeinrichtung in Abhängigkeit eines Schließmechanismus der Schließeinrichtung angeordnet.Preferably, the aforesaid taper or indentation for the above-described temporary locking in a locking device depending on a locking mechanism of the locking device is arranged between the outermost end of the end piece of the locking end and the external thread.
In einer alternativen Ausgestaltung ist das Endstück des Schließ-Endes lösbar unter Verwendung eines Gewindes des Schließ-Endes mit dem Sicherungselement verbunden.In an alternative embodiment, the tail of the locking end is releasably connected to the securing element using threads of the locking end.
In einer bevorzugten Ausgestaltung weist das Endstück des Schließ-Endes eine Kavität auf, die ein Teil des Hohlraums des Sicherheitselements ist, wenn das Endstück des Schließ-Endes mit dem Sicherheitselement verbunden ist. Auf diese Weise setzt sich der Hohlraum bis an sein äußerstes Ende fort und ein gewaltsames Auftrennen der Außenhülle des Sicherungselements im Bereich des Schließ-Endes führt ebenfalls zum sofortigen Austreten des Fluids.In a preferred embodiment, the terminus of the closing end has a cavity which is part of the cavity of the security element when the terminus of the closing end is connected to the security element. In this way, the hollow space continues to its outermost end and forcibly separating the outer casing of the securing element in the area of the closing end also leads to the fluid escaping immediately.
Bevorzugt verläuft die Kavität des Endstücks des Schließ-Endes bis zu der oben genannte Verjüngung oder Einkerbung zur Arretierung des Sicherungselements in einem Schließmechanismus.Preferably, the cavity of the end piece of the locking end runs up to the above-mentioned taper or notch for locking the securing element in a locking mechanism.
Damit der Hohlraum im Sicherungselement einen möglichst großen Durchmesser haben kann, aber die zum Arretieren des Sicherungselements in einem Schließmechanismus benötigte Verjüngung bzw. Einkerbung diesen Hohlraum nicht unnötig begrenzen bzw. in dem Bereich der Verjüngung bzw. Einkerbung das Sicherheitselement aufgrund des Hohlraums nicht zu dünnwandig wird, ist insbesondere bei sehr kleinen Schlossbügeln, beispielsweise Vorhängeschlössern, die Verwendung des Endstücks bzw. der Endstücke vorteilhaft, um auch für diese kleinen Schlossbügel einen großen Hohlraum zu schaffen.To allow the cavity in the fuse element to have as large a diameter as possible, but with the taper needed to lock the fuse element in a locking mechanism or notch does not unnecessarily limit this cavity or the security element does not become too thin-walled in the area of the taper or notch due to the cavity, the use of the end piece or end pieces is advantageous, particularly with very small lock shackles, for example padlocks, in order to also to create a large cavity for these small lock shackles.
Die gestellte Aufgabe wird auch durch ein Verfahren zum Herstellen eines Sicherungselements gemäß der vorhergehenden Art mit folgenden Verfahrensschritten gelöst: Bereitstellen eines hohlen Sicherungselemente-Rohlings; Einbringen eines Gewindes in zumindest ein offenes Ende des Sicherungselemente-Rohlings; Fixieren eines Einfüllventils an einem offenen Ende des Sicherungselemente-Rohlings mittels des Gewindes; Formen des Sicherungselemente-Rohlings zum Erhalten einer Endform, die der Endform des Sicherungselements entspricht; und Befüllen des Hohlraums des Sicherungselemente-Rohlings mit einem unter Druck stehenden Fluid als Schutzmittel am Einfüllventil, wobei das Einfüllventil nach Beenden des Befüllens automatisch den Hohlraum abschließt.The stated object is also achieved by a method for producing a fuse element according to the preceding type with the following method steps: providing a hollow fuse element blank; introducing a thread into at least one open end of the fuse element blank; fixing a filling valve to an open end of the fuse element blank by means of the thread; shaping the fuse element blank to obtain a final shape corresponding to the final shape of the fuse element; and filling the cavity of the fuse element blank with a pressurized fluid as a protective agent at the filling valve, the filling valve automatically closing off the cavity after filling is completed.
Das Bereitstellen eines hohlen Sicherungselemente-Rohlings erfolgt in einer bevorzugten Ausgestaltung durch ein Bohren eines Loches entlang einer Längsausrichtung eines länglichen massiven Sicherungselemente-Rohling zum Erhalten eines Hohlraums, ohne den Sicherungselemente-Rohling zu durchbohren. Der Bohren-Schritt bewirkt insbesondere, dass ein Abstand zwischen Schließ-Ende und Hohlraum eingestellt wird, der ausreichend groß ist, bevorzugt größer als der Durchmesser des resultierenden Sicherungselements.In a preferred embodiment, a hollow fuse element blank is provided by drilling a hole along a longitudinal direction of an elongate solid fuse element blank to obtain a cavity without piercing the fuse element blank. In particular, the drilling step has the effect of setting a distance between closing end and cavity which is sufficiently large, preferably larger than the diameter of the resulting fuse element.
Das Bereitstellen eines hohlen Sicherungselemente-Rohlings erfolgt in einer alternativen Ausgestaltung durch das Herstellen eines länglichen Hohlkörpers, insbesondere eines Rohres, der an beiden gegenüberliegenden Enden offen ist.In an alternative embodiment, a hollow fuse element blank is provided by producing an elongate hollow body, in particular a tube, which is open at both opposite ends.
Es ist mitunter vorgesehen, bestehende Schlösser von massiven Schlossbügeln auf die hier beschriebenen hohlen Sicherungselemente umzurüsten. Das Bereitstellen eines hohlen Sicherungselemente-Rohlings erfolgt in diesen Fällen durch das Herstellen eines länglichen Hohlkörpers, insbesondere eines Rohres, der an beiden gegenüberliegenden Enden offen ist.It is sometimes planned to convert existing locks from solid lock shackles to the hollow security elements described here. In these cases, a hollow fuse element blank is provided by producing an elongate hollow body, in particular a tube, which is open at both opposite ends.
Beide Enden der massiven Schlossbügel werden abgetrennt und werden entsprechend der oben beschriebenen Endstücken für ein Schließ-Ende und ein Befüll-Ende ausgeformt bzw. ausgestaltet. Alternativ werden die Endstücke separat hergestellt.Both ends of the solid shackle are severed and are shaped according to the locking end and filling end end pieces described above. Alternatively, the end pieces are manufactured separately.
Dabei werden insbesondere die beschriebenen Gewinde und Kavitäten eingebracht. Anschließend wird das Endstück des Befüll-Endes an das Sicherheitselement angeordnet. Anschließend wird das Endstück des Schließ-Endes an das Sicherheitselement angeordnet.In particular, the described threads and cavities are introduced. The end piece of the filling end is then arranged on the security element. Then the tail of the closing end is placed on the security element.
Das Anordnen des Endstücks bzw. der Endstück können durch Verschrauben, Verschweißen oder Verkleben mit dem Sicherheitselement mechanisch lösbar oder mechanisch nicht-lösbar verbunden werden.The arrangement of the end piece or end pieces can be mechanically detachably or mechanically non-detachably connected to the security element by screwing, welding or gluing.
Die Verfahrensschritte können auch untereinander vertauscht sein, so kann der Formen-Schritt auch vor dem Fixieren-Schritt und/oder dem Einbringen-Schritt erfolgen. Der Formen-Schritt kann auch nach dem Befüllen-Schritt erfolgen.The process steps can also be interchanged with one another, so the shaping step can also take place before the fixing step and/or the introduction step. The forming step can also occur after the filling step.
Die gestellte Aufgabe wird auch durch ein Verfahren zum Herstellen eines Schlosses nach einem der vorhergehenden Art unter Verwendung eines Sicherungselements gemäß einem der vorhergehenden Art mit folgenden Verfahrensschritten gelöst: Einbringen des Befüll-Endes in eine Schließeinrichtung; und Lagern des Befüll-Endes durch Aktivieren eines Lager-Mechanismus der Schließeinrichtung.The stated object is also achieved by a method for producing a lock according to one of the preceding types using a security element according to one of the preceding types with the following method steps: introducing the filling end into a locking device; and storing the filling end by activating a storage mechanism of the closure device.
Das Einbringen in die Schließeinrichtung beinhaltet bevorzugt auch das Vorhandensein einer entsprechenden Öffnung in der Schließeinrichtung. Durch das Einbringen des Befüll-Endes in die Schließeinrichtung ist das Befüll-Ende nicht mehr von außerhalb der Schließeinrichtung zugänglich, ohne das Schloss zu zerstören. Das Befüll-Ende ist also durch die Schließeinrichtung geschützt.The introduction into the closure device preferably also includes the presence of a corresponding opening in the closure device. By introducing the filling end into the locking device, the filling end is no longer accessible from outside the locking device without destroying the lock. The filling end is therefore protected by the closing device.
Die gestellte Aufgabe wird zudem auch durch ein Verfahren zum Behindern eines Diebstahlversuchs mit einem Schloss der vorhergehenden Art gelöst, wobei beim unerlaubten Öffnen des Hohlraums ein unter Druck stehendes Fluid als Schutzmittel aus dem Inneren des Sicherungselements austritt.The stated object is also achieved by a method for preventing an attempted theft with a lock of the above type, with a pressurized fluid escaping from the interior of the security element as a protective agent when the cavity is opened without permission.
Die Aussagen über das Sicherungselement bzw. das Schloss treffen in gleicher Weise auch für die entsprechenden Herstellungsverfahren zu.The statements made about the security element or the lock also apply in the same way to the corresponding manufacturing processes.
Das Fluid ist als Schutzmittel eingebracht und dient dazu beim Austreten eine zusätzliche Schutzwirkung zu entfalten, die den Diebstahlversuch verhindern oder sehr stark erschwert (behindert), um den zu sichernden Gegenstand noch besser zu schützen. Das Schutzmittel umfasst geeignete Gase oder Flüssigkeiten, die beispielsweise übelriechende Substanzen, Signalfarben, Reizsubstanzen und/oder künstliche DNA enthalten. Eine Zwei-Komponenten bzw. eine Drei-Komponenten-Mischung, wie oben beschrieben wurde, ist zu bevorzugen.The fluid is introduced as a protective agent and serves to develop an additional protective effect when escaping, which prevents the attempted theft or makes it very difficult (hindered) in order to protect the object to be secured even better. The protective agent comprises suitable gases or liquids containing, for example, malodorous substances, signal colors, irritant substances and/or artificial DNA. A two-component or a three-component mixture as described above is preferred.
Ein derartiges Schloss oder Sicherungselement hat eine Reihe von Vorteilen. Einerseits ist es ausreichend robust, um das Fluid bei bestimmungsgemäßen Gebrauch im Hohlraum zu halten. Dies erhöht die Sicherheit, dass der Nutzer das Schloss verwenden kann, ohne Gefahr zu laufen, dass er mit dem ggf. aggressiven Schutzmittel in Berührung kommt. Zudem sind der Aufbau und die Herstellung wesentlich einfacher. Aufwendige Einsätze zum Abschließen des Hohlraums können weggelassen werden. Der Druck des Fluids führt zu einem schnellen, beispielsweise explosionsartigen, Ausströmen des Fluids, wodurch der Dieb erschreckt wird ohne dass er verletzt wird. Das Fluid ist ein Schutzmittel, was beim Austreten aus dem Hohlraum eine Schutzwirkung entfaltet und beispielsweise den Dieb markiert (Signalfarbe, künstliche DNA) und/oder zumindest behindert (Reizgas, übelriechende Flüssigkeit, Rauch).Such a lock or security element has a number of advantages. On the one hand, it is sufficiently robust to keep the fluid in the cavity when used as intended. This increases the security that the user can use the lock without running the risk of coming into contact with the possibly aggressive protective agent. In addition, the structure and manufacture are much simpler. Elaborate inserts to close off the cavity can be omitted. The pressure of the fluid causes the fluid to flow out quickly, for example explosively, which frightens the thief without injuring him. The fluid is a protective agent, which develops a protective effect when it exits the cavity and, for example, marks the thief (signal color, artificial DNA) and/or at least hinders it (irritant gas, foul-smelling liquid, smoke).
Die Verwendung unterschiedlicher Fluide als Schutzmittel im Sicherungselement erhöht die Sicherheit, da ein erstes Fluid möglicherweise den Dieb markiert (Signalfarbe, künstliche DNA) und ein weiteres Fluid den Dieb behindert (Reizgas, Rauch).The use of different fluids as protective means in the security element increases security since a first fluid may mark the thief (signal color, artificial DNA) and another fluid hinders the thief (irritant gas, smoke).
Das Sicherungselement kann im gefüllten Zustand an die Schließeinrichtung angebracht (montiert) werden. Innerhalb definierter Wartezyklen kann mittels des Ventils der Hohlraum (nach-) gefüllt werden.The securing element can be attached (assembled) to the locking device in the filled state. The cavity can be (re)filled within defined waiting cycles by means of the valve.
Im Hohlraum kann auch ein Drucksensor angeordnet sein, wobei der Drucksensor einen Druckabfall im Hohlraum erfasst und an eine Alarmeinrichtung meldet. Der Drucksensor ist bevorzugt energieautark und sendet das Erfassungssignal. Das Erfassungssignal wird bevorzugt über eine digitale Schnittstelle direkt als Meldung auf ein Mobilfunkgerät, einen Wachschutz oder zur Polizei unter Nennung des Einbruchsort abgesetzt.A pressure sensor can also be arranged in the cavity, with the pressure sensor detecting a drop in pressure in the cavity and reporting it to an alarm device. The pressure sensor is preferably self-sufficient in terms of energy and transmits the detection signal. The detection signal is preferably sent directly via a digital interface as a message to a mobile phone, a security guard or to the police, stating the location of the break-in.
Das Austreten des Fluids wird mittels eines Drucksensors detektiert und über eine digitale Schnittstelle des Drucksensors berichtet wird. Dabei wird beispielsweise die durch das Austreten des Fluids freigesetzte Energie einen Energiespeicher des Drucksensors laden, der dann den Drucksensor mit Energie versorgt, um den Bericht mittels der digitalen Schnittstelle abzusetzen. Alternativ verfügt der Drucksensor über eine Batterie, um den Bericht mittels der digitalen Schnittstelle abzusetzen. Der Drucksensor kann über eine eigene Teilnehmerkennung mit einem Mobilfunknetz kommunizieren.The escape of the fluid is detected by means of a pressure sensor and is reported via a digital interface of the pressure sensor. In this case, for example, the energy released as a result of the fluid escaping will charge an energy store in the pressure sensor, which then supplies the pressure sensor with energy in order to send the report using the digital interface. Alternatively, the pressure sensor has a battery to send the report via the digital interface. The pressure sensor can communicate with a cellular network via its own subscriber identifier.
Bereits der Zerstörungsversuch auch bei nur geringer Öffnung des Hohlraums führt zum explosionsartigen Austritt des Fluids. Unweigerlich wird der Diebstahl erschwert, verzögert oder verhindert, gemeldet und die beteiligte(n) Person(en) und das verwendete Gerät wird markiert (künstliche DNA, Signalfarbe).The attempt to destroy the cavity, even if only slightly opened, leads to the fluid escaping explosively. Inevitably, theft is made more difficult, delayed or prevented, reported and the person(s) involved and the device used are marked (artificial DNA, signal color).
Zudem kann das erfindungsgemäße Sicherungselement mit nur wenigen Handgriffen in eine konventionelle (standardisierte) Schließeinrichtung positioniert werden.In addition, the security element according to the invention can be positioned in a conventional (standardized) locking device with just a few manipulations.
Das Sicherungselement sorgt für einen Überraschungseffekt, der einen Rückzug des Diebs auslösen wird. Selbst wenn ein Dieb bereits einen Diebstahlsversuch an einem solchen Sicherungselement durchgeführt hat, bleibt ihm ungewiss, mit welchem Schutzmittel das aktuell angegriffene Sicherungselement befüllt ist. Ein evtl. Mitführen von Schutzkleidung oder Gasmaske sind eher auffällig und als zusätzliche Last für jeden Dieb hinderlich. Das Sicherungselement hat eine abschreckende Wirkung auf den potentiellen Dieb.The security element provides a surprise effect that will cause the thief to retreat. Even if a thief has already attempted to steal such a security element, he remains uncertain as to which protection means the currently attacked security element is filled with. Possibly carrying protective clothing or a gas mask are rather conspicuous and, as an additional burden, are a hindrance for every thief. The security element has a deterrent effect on the potential thief.
Infolge eines Druckabfallsignals kann eine Verbindung zu anderen Sicherungs- und Benachrichtigungsanlagen aufgebaut werden. Dabei kann die Benachrichtigung auf digitalem Wege sowohl an den Eigentümer, den Betreiber oder den Nutzer sowie an den Wachschutz oder die Polizei erfolgen.A connection to other security and notification systems can be established as a result of a pressure drop signal. The notification can be sent digitally to the owner, the operator or the user as well as to the security guard or the police.

In Fig. la-b sind zwei verschiedene Ausführungsbeispiele von erfindungsgemäßen Sicherungselementen 2 dargestellt. In
Das Sicherungselement 2 ist ein starrer Bügel, der einen Hohlraum 23 aufweist. In den Hohlraum 23 ist ein Fluid 4 als Schutzmittel eingebracht. Das Sicherungselement 2 hat zwei Enden, ein Schließ-Ende 21 an einem ersten Ende des Sicherungselements 2 und ein Befüll-Ende 22 an einem vom ersten Ende entfernten zweiten Ende des Sicherungselements 2.The securing
Das Schließ-Ende 21 ist integraler Bestandteil des Sicherungselements 2. Beispielsweise ist das Sicherungselement 2 aus einem massiven Sicherungselemente-Rohling entstanden, in das der Hohlraum 23 eingebracht wurde (siehe
Das Befüll-Ende 22 am vom Schließ-Ende 21 entfernten zweiten Ende des Sicherungselements 2 ist ebenfalls integraler Bestandteil des Sicherungselements 2. Der Hohlraum 23 ist zum Befüll-Ende 22 durch ein Einfüllventil am Befüll-Ende 22 zum Einbringen des Fluids 4 in den Hohlraum 23 abgeschlossen. Das Befüll-Ende 22 weist ein Gewinde, insbesondere einen Gewindeeinsatz, zum Fixieren des Einfüllventils am Befüll-Ende 22 auf. Das Befüll-Ende 22 ist zumindest zeitweise in der Schließeinrichtung 3 des Sicherungselements 2 gelagert. Das Befüll-Ende 22 kann daher bei aktiviertem Lager-Mechanismus der Schließeinrichtung 3 in seiner axialen Bewegungsrichtung 10 gehemmt oder blockiert werden, sodass das Sicherungselement 3 nicht aus der Schließeinrichtung 3 entfernt werden kann. Eine Drehbewegung 11 ist bei geöffnetem Schließmechanismus dennoch möglich. Das Befüll-Ende 22 ist beispielsweise ein integraler Bestandteil des Sicherungselements 3. Beispielsweise ist das Sicherungselement 2 aus einem massiven Sicherungselemente-Rohling entstanden, in das das Ventil zum Abschließen des Hohlraums 23 fixiert wurde (siehe

Durch das Verwenden eines Endstücks 226 kann der Hohlraum 23 des Sicherungselements 2 einen maximalen Durchmesser haben, da die Verjüngung 223 den Hohlraum 23 nicht in seinen Abmessungen beschränkt. Das Vergrößern des Hohlraums 23 ermöglicht die Verwendung dünnwandigerer Hohlkörper für das Sicherungselements 2 und damit einen geringeren Materialaufwand. Zudem wird keine Schwachstelle im Bereich der Verjüngung 223 aufgrund zu dünnwandiger Sicherungselemente 2 geschaffen, wodurch bei häufiger Benutzung möglicherweise ein ungewollter Fluidaustritt erfolgen könnte.By using an
Optional wird im weiteren Unterschied zu den vorhergehenden Figurenbeschreibungen ein Ventil-Adapter 225 vorgesehen, um das Einfüll-Ventil 221 in das Befüll-Ende 22 zu fixieren. Dazu weist der Ventil-Adapter 225 ein Außengewinde 2251 auf, um mit dem Gewinde 222 des Befüll-Endes 22 lösbar verbunden zu werden. Der Ventil-Adapter 225 weist zudem ein Innengewinde auf, um das Einfüll-Ventil 221 fixieren zu können. In einer kompakten Ausgestaltung weist der Ventil-Adapter zudem eine Verjüngung 2252 auf, die in eine Ausnehmung (nicht dargestellt) des Endstücks 226 eingebracht werden kann.
