[0019] Corresponding parts are marked with the same reference symbols in all figures.

[0020] Fig. Figure 1 schematically shows in perspective a safety device 1 for securing mobile objects 12 (shown in Fig. 2) and is designed as an anti-theft module.

[0021] The safety device 1 comprises a locking module 2 with a housing 4, a lock 6 and a retraction mechanism 8 arranged in the housing 4, as well as a safety cable 10.

[0022] The housing 4 is designed in particular as a protective housing. For example, the housing 4 can be configured according to IEC 60529 for protection according to one of the protection classes IP65, IP66, IP67 or IP68, in particular coated and / or made of a suitable material with suitable seals.

[0023] The locking module 2 is designed as a retractable lock. For this purpose, the safety cable 10 is rigidly coupled to the retraction mechanism 8 on one side and can be releasably locked or locked to the lock 6 on the other.

[0024] The retraction mechanism 8 comprises a winding element 8.1, which is arranged to be wound and unwound in the housing 4 and is configured such that it is extended or can be extended by pulling on a free end 10.1 of the safety rope 10, so that the safety rope 10 can be variably extended and attached to mobile objects 12. The winding element 8.1 is specifically designed as an element that can be unwound by an external force and rewound automatically.

[0025] The free end of the rope 10.1 comprises a locking element 10.1.1, which can be inserted into and locked into the lock 6. After the locking mechanism is released, the winding element 8.1 and the safety rope 10 are automatically retracted into the housing 4. An opposite end of the rope 10.2 is coupled to the winding element 8.1, in particular, permanently connected to it.

[0026] A variably extendable safety rope 10 is understood in particular to be a variable extension according to arrow 100 between a maximum available rope extension and a minimum available rope extension.

[0027] Preferably, the winding element 8.1 is designed as a mechanical drive element. For example, the winding element 8.1 is designed as a spring drive. In particular, the winding element 8.1 is designed as a coil spring 8.1.1, for example as a self-winding coil spring or as another suitable spring element, in particular as a tension spring. The coil spring 8.1.1 is used in particular as a mechanical spring drive with constant torque. This enables the safety cable 10 to be wound up automatically with constant force over many revolutions.

[0028] For example, the safety rope 10 is designed as a wire rope fabric, a flexible plastic rope with a wire core 10.3, or the like. In particular, the safety rope 10 is designed to be cut-resistant or largely inseparable.

[0029] Preferably, a winding carrier 14 is rotatably mounted in the housing 4. The winding carrier 14 is freely rotatable, particularly under the influence of the winding element 8.1. For example, it is rotatably mounted in the housing 4 about a rotational axis 14.0.

[0030] The lock 6 can, for example, be designed as a lockable lock 6, in particular an electromechanical lock 6 or a mechanical lock 6. The lock 6 comprises a counter-locking element 6.1 corresponding to the locking element 10.1.1.

[0031] The lock 6 can, for example, be configured to be locked or unlocked by means of a QR code, a digital numeric code, a digital PIN, or the like. In other words, the lock 6 is designed as an electronic lock 6, in particular an electronic combination lock, an electronic code lock, an electronic PIN lock, or the like. For this purpose, the lock 6 can include a corresponding input unit 6.2, in particular a touch display or the like. The input unit 6.2 is, for example, integrated into the housing 4 at a suitable location accessible from the outside.

[0032] Alternatively or additionally, the lock 6 can be designed as a mechanical lock 6, in particular as an analog combination lock or a key lock. The combination lock 6 can, for example, comprise at least one or more rotary knobs as an input unit 6.2, which are rotatably mounted in the housing 4 and accessible and operable from the outside. Alternatively, the key lock 6 can, for example, comprise at least one or more rotary knobs as an input unit 6.2, which are rotatably mounted in the housing 4 and accessible and operable from the outside.

[0033] Additionally, the security device 1 can include a communication interface 16, for example a radio interface, a Bluetooth interface, a WLAN interface or the like, via which the lock 6 can be remotely controlled, in particular unlocked or locked. For example, corresponding application software can be implemented on a mobile device, in particular a mobile phone, by means of which the lock 6 can be remotely unlocked or locked.

[0034] Furthermore, the security device 1 can comprise at least one computing unit 18, in particular an integrated circuit, and / or a sensor unit 20, in particular a security sensor, for example a theft sensor, a vibration sensor, a shock sensor, a motion sensor or the like.

[0035] The sensor unit 20, the computing unit 18 and the communication interface 16 can in particular be coupled to each other in such a way as to signal technology and interact with each other in such a way that, in the state of the security device 1 being attached to the mobile objects 12 and in the closed and secured state of the lock 6, a movement of the mobile objects 12 and / or a vibration on components of the security device 1 is detected, analyzed and monitored.

[0036] For example, compliance with and / or exceedance of limit values ​​of the recorded sensor values ​​can indicate an operational state or an undesired state, such as an attempted theft, and an alarm signal can be output via an output unit 22, for example a loudspeaker, a display unit or the like, in the housing 4 and / or sent via the communication interface 16 to a central unit, in particular a monitoring center, to a mobile unit of the owner of the mobile objects 12 or the like.

[0037] Additionally, a tracking unit 24, for example a GPS tracker or the like, can be integrated into the housing 4. The tracking unit 24 can be configured such that when the tracking unit 24, and thus the mobile objects 12 to be monitored, move away from a predetermined location, a movement signal is regularly transmitted in real time directly via the tracking unit 24 and / or via the communication interface 16.

[0038] For example, the tracking unit 24 and / or the sensor unit 20 can be activated when the lock 6 is closed. Alternatively or additionally, the tracking unit 24 and / or the sensor unit 20 can be activated manually, or the communication interface 16 can be activated remotely. Alternatively or additionally, the tracking unit 24 can only be activated when a theft alarm is detected. This makes the tracking unit 24 particularly energy-efficient.

[0039] In particular, the safety device 1 is designed as a self-contained unit powered by a battery 26 or a rechargeable battery 28. For example, the electronic components, such as the communication interface 16, sensor unit 20, computing unit 18, electronic input unit 6.2, tracking unit 24 and others, can be powered by the internal battery 26 or the internal battery 28.

[0040] The safety device 1 can also have a charging interface 30 on the housing 4 for charging the accumulator 28.

[0041] Fig. Figure 2 shows a schematic perspective view of the security device 1, mounted on mobile objects 12. The mobile objects 12 can be valuable items, for example at least one table 12.1, chairs 12.2, bicycles, motorcycles, boats, vehicle trailers or the like.

[0042] The housing 4 of the locking module 2 is securely attached to one of the mobile objects 12, for example, a table 12.1. In particular, the housing 4 can be attached to one of the mobile objects 12, such as the table 12.1, by means of a material connection, a force connection, and / or a form connection. For example, the housing 4 is glued, riveted, sealed, or similarly attached to the table 12.1.

[0043] The safety rope 10 can, for example, be threaded through openings 12.3 in the mobile objects 12 and connect them together before the free end of the rope 10.1 (shown in Fig. 1) is inserted into lock 6 and locked.

[0044] Fig. Figure 2 shows only one possible application for the security device 1, designed as a self-contained anti-theft device with retraction mechanism 8 (shown in Fig. 1) Other applications are possible, such as works of art, motorcycles, bicycles.

[0045] Fig. Figure 3 schematically shows the safety device 1 in a sectional view.

[0046] For example, the housing 4 is arranged such that both the winding element 8.1 and the safety rope 10 can be wound and unwound separately in the housing 4.

[0047] For example, the housing 4 can have two housing sections 4.1 and 4.2 arranged one above the other in the vertical direction z. In a first housing section 4.1, the winding element 8.1 can be arranged, and separately in a second housing section 4.2, the safety cable 10 can be arranged to be wound up and unwound.

[0048] The winding support 14 can, for example, be configured as a winding drum or winding roller. In particular, the winding support 14 can be configured as a double roller or a double drum. For example, the winding support 14 can comprise two winding bearings 14.1, 14.2, one of which extends into each of the housing sections 4.1, 4.2.

[0049] A first winding bearing 14.1 is designed, for example, as a bearing bolt, bearing pin or the like, on which the winding element 8.1 is mounted in the first housing section 4.1 in a way that allows it to be wound up and unwound.

[0050] A second winding bearing 14.2 is designed, for example, as a bearing bolt, bearing pin or the like, on which the safety rope 10 can be unwound in the second housing section 4.2 and automatically wound up by means of the winding element 8.1.

[0051] Between housing sections 4.1 and 4.2, the winding carrier 14 can have a separating element 14.3, in particular partitions, separating discs or the like, for the separate winding and unwinding of the winding element 8 and the safety cable 10. The separating element(s) 14.3 can optionally have guides, in particular grooves, openings, webs or the like, for guiding the winding element 8.1 and the safety cable 10 during winding and unwinding.

[0052] Alternatively, the coil spring 8.1.1 can be arranged loosely in the associated first housing section 4.1 and thus without a first winding bearing 14.1 and can be arranged, due to its spring force, to automatically rewind itself in an orderly manner from the unwound state.

[0053] The winding support 14 can have an H-shape, particularly in cross-section. A central web 14.4 of the H-shape forms the second winding bearing 14.2. One or both legs 14.5 each form the separating element 14.3. The first winding bearing 14.1 extends perpendicularly away from the outside of one of the legs 14.5. An inner wall 4.3 of the housing 4 can be designed as a separating element 14.3 and / or as a support element 4.4.

[0054] The winding element 8.1, designed as a coil spring 8.1.1, can in particular be a leaf spring or a metal strip and be wound in several turns around the first winding bearing 14.1.

[0055] The safety rope 10 can, in particular, be a round rope with a wire core 10.3, an outer and / or inner wire mesh, an outer and / or inner wire reinforcement, or the like. The safety rope 10 is, in particular, robust and largely indestructible, especially cut-resistant, tear-resistant, break-resistant, tensile-resistant, or the like.

[0056] Depending on the dimensions of the safety rope 10 and / or winding carrier 14, the safety rope 10 can be wound around the second winding bearing 14.2 in several turns.

[0057] Fig. Figure 4 schematically shows the safety device 1 in a sectional view. In this Fig.Figure 4 shows both winding methods for the safety rope 10: The safety rope 10 can be wound largely loosely and randomly on the second winding bearing 14.2 (left side of the second housing section 4.2) or in an ordered manner (right side of the second housing section 4.2) in several windings.
