Description

[0001] The invention relates to a safety device for a plurality of mobile objects.

[0002] Safety devices for mobile objects, such as outdoor seating for a restaurant, a bicycle, a motorcycle, a boat, or the like, are generally known.

[0003] A bicycle lock for securing a bicycle is known from DE 20 2006 014 271 U1.

[0004] Another bicycle lock for securing a bicycle is known from US 5 251 464 A.

[0005] The invention is based on the objective of providing a safety device for a plurality of mobile objects which can be attached and detached easily and securely.

[0006] The problem is solved according to the invention by a safety device having the features of claim 1.

[0007] Advantageous embodiments of the invention are the subject of the dependent claims.

[0008] The safety device according to the invention (also called a safety unit) is designed to secure a plurality of mobile objects.The safety device comprises a locking module with a housing, a lock, and a retraction mechanism arranged in the housing, as well as a safety cable which is rigidly coupled to the retraction mechanism on one side and can be detachably locked or locked to the lock on the other side, wherein the retraction mechanism comprises a winding element which is arranged to be wound and unwound in the housing and is configured such that it is extended or extendable by pulling on a free end of the safety cable, so that the safety cable can be variably extended and attached or affixed to the mobile objects, connecting them to one another, wherein the free end of the cable comprises a locking element which can be inserted and locked into the lock or inserted and locked, and wherein the winding element and the safety cable can be automatically retracted or are retracted into the housing after the locking mechanism is released.

[0009] In particular, the winding element is automatically wound up in the housing after the locking mechanism is released, and as a result, the safety cable is automatically retracted into the housing.

[0010] In particular, the safety device is designed to secure several mobile objects by connecting them to each other using a safety rope and locking or securing them in a releasable manner.

[0011] A variably extendable safety rope is understood to mean, in particular, a variable extension between a maximum available rope extension and a minimum available rope extension.

[0012] Preferably, the winding element is designed as a mechanical drive element, in particular as a spring drive. For example, the winding element can be designed as a coil spring or as a tension spring. The coil spring is particularly suitable as a mechanical spring drive with constant torque. This enables winding with constant force over many revolutions.

[0013] For example, the safety rope is designed as a wire rope weave, a flexible plastic rope with a wire core, or the like. In particular, the safety rope is designed to be cut-resistant or virtually inseparable.

[0014] In one possible embodiment, the housing is designed such that both the winding element and the safety cable can be wound and unwound separately within the housing. For example, the housing can have two housing sections arranged one above the other in the vertical direction, with the winding element in a first housing section and the safety cable being wound and unwound separately in a second housing section.

[0015] Furthermore, the safety device is designed to be weatherproof. For this purpose, the housing is specifically designed as a protective enclosure, which is, in particular, waterproof, shockproof, dustproof, moisture-proof, EMC-resistant, or similar. For example, the protective enclosure can be configured according to IEC 60529 for protection classes IP65, IP66, IP67, or IP68, and may be coated and / or made of a suitable material with appropriate seals.

[0016] Preferably, a winding support is rotatably mounted in the housing. The winding support is freely rotatable, particularly under the influence of the winding element. The winding support can, for example, be designed as a winding drum or winding roll. The winding support can, in particular, be designed as a double roll or a double drum.

[0017] In a further development of the invention, the winding carrier can comprise two winding bearings, one of which extends into one of the housing sections.

[0018] The lock can be designed, for example, as a lockable lock, in particular an electromechanical lock, such as a QR code lock, a PIN code lock, as a mechanical lock, in particular a combination lock or a key lock.

[0019] The electromechanical lock may in particular include a communication interface through which the lock can be remotely controlled, in particular by means of application software (also called app) that is implemented on a mobile device, such as a mobile phone, and can be unlocked or locked.

[0020] Additionally, the security device may include at least one security sensor, in particular an anti-theft sensor, for example a shock sensor.

[0021] Furthermore, the safety cable and the retraction mechanism, in particular the winding element (e.g., a coil spring), can be directly and rigidly connected. For example, the retraction mechanism, acting as a winding element, can include the coil spring, which is arranged within the housing in such a way that it can be wound and unwound and is directly and rigidly connected to the safety cable. This has the technical effect of enabling reliable and automatic retraction of the safety cable into the housing after use by means of the coil spring.This direct connection between the retraction mechanism and the safety rope, as opposed to an indirect connection via a drum or the like, enables efficient transmission of the spring force to the safety rope and, in particular, minimizes the risk of slippage or malfunctions, while simultaneously allowing for safe and smooth retraction of the safety rope, thereby improving operational safety and handling of the device under stress.

[0022] A further development provides a braking unit designed to decelerate the retraction mechanism when the safety rope is being retracted. The braking unit is coupled to the retraction mechanism in such a way that the safety rope can be retracted smoothly, particularly at a constant speed. For example, the braking unit can include a spring unit that is locked in the inactive state of the braking unit and unlocked in the active state. The braking unit specifically acts as a retraction brake. As a retraction brake, the braking unit is designed to dampen any tensile force exerted by the safety rope when the locking mechanism is released. The spring unit can be designed, for example, as a drive spring, a tension spring with brake shoes, in combination with a rotary brake, or the like. Alternatively, the spring unit can be designed as a retraction spring with a predetermined retraction spring force.Furthermore, the winding element, for example a rope drum, and the brake unit can be engaged in a single engagement, for example in a tooth engagement, or in another suitable combination to ensure that the safety rope is retracted evenly.

[0023] Additionally, a locking unit may be provided, comprising at least one retraction-stop mechanism and / or one extension-stop mechanism. The locking unit may be designed as a mechanical or electromagnetic lock, which secures the winding element, in particular the cable drum, and / or the safety cable.

[0024] The retraction-stop mechanism can, for example, be configured to secure the safety rope in any desired extended position. For instance, the retraction-stop mechanism can be designed as a locking hook that engages with the winding element and / or the safety rope, for example, with a corresponding locking receptacle, to fix and hold the safety rope in the respective extended position. Preferably, the retraction-stop mechanism is designed as a locking device for the winding element, for example, a releasable mechanical lock or a releasable magnetic lock.

[0025] The extension-stop mechanism can, for example, be designed to secure an unused length of rope against being pulled out while the lock is engaged. For instance, the extension-stop mechanism can be designed as a locking hook that engages the safety rope, for example in a corresponding locking receptacle, to fix and hold it in the relevant extended position.

[0026] For example, a mechanical release element, in particular a release button, can be provided on the outside of the housing to unlock the locking unit.

[0027] Exemplary embodiments of the invention are explained in more detail below with reference to drawings. It shows:

[0033] 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.

[0034] 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.

[0035] The retraction mechanism 8 comprises a winding element 8.1, which is arranged to be wound and unwound within 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, connecting them to one another. The winding element 8.1 is specifically designed as an element that can be unwound by an external force and rewound automatically.

[0036] In particular, the safety device 1 is designed to secure several mobile objects 12 by connecting them to each other using the safety rope 10 and releasably locking them, as shown in Figure 2 shown.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In particular, the safety cable 10 and the retraction mechanism 8 are directly and rigidly connected to each other. For example, the retraction mechanism 8 can, as a winding element 8.1, include the coil spring 8.1.1 (also called a winding spring), which is arranged in the housing 4 such that it can be wound and unwound and is directly and rigidly connected to the safety cable 10. This direct connection between the coil spring 8.1.1 and the safety cable 10, as opposed to an indirect connection via a drum or the like, enables efficient transmission of the spring force to the safety cable 10, minimizes the risk of slippage or malfunctions, and allows for safe and smooth retraction of the safety cable 10.

[0043] 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.

[0044] 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.

[0045] 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.

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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

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.

[0059] 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 Figure 1 ) is inserted into lock 6 and locked.

[0061] Figure 3 schematically shows the safety device 1 in a sectional view.

[0062] 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.

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.

[0065] 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.

[0066] 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.

[0067] 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 8.1 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.

[0068] 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.

[0069] 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.

[0070] 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.

In particular, the first brake unit 32.1 engages with the separating element 14.3 via the toothing 38 in order to decelerate the winding carrier 14 when the first brake unit 32.1 is activated, such that the safety rope 10 is retracted evenly, in particular at a constant speed.

[0076] Alternatively or additionally, a second brake unit 32.2 can be provided. The second brake unit 32.2 can, for example, be centrally engaged with the winding carrier 14 via an axis, in particular the central web 14.4, in order to brake the winding carrier 14 when the second brake unit 32.2 is activated in such a way that the safety rope 10 is retracted evenly, in particular at a constant speed.

The retraction-stop mechanism 34.1 is specifically designed to secure the winding element 8.1, the safety cable 10, and / or the winding carrier 14 in any desired extension position. For example, after activation, the locking pin or locking hook can be configured to engage directly in the winding carrier 14, the winding element 8.1, and / or the safety cable 10, for example, in a corresponding detent receptacle, in order to fix and hold the safety cable 10 in the respective extension position. Preferably, the retraction-stop mechanism 34.1 is designed as a locking mechanism for the winding element 8.1 or the winding carrier 14, for example, as a releasable mechanical lock. Alternatively, the retraction-stop mechanism 34.1 can be designed as a releasable magnetic lock.For this purpose, for example, the locking unit 34 on the one hand and the winding carrier 14, the winding element 8.1 and / or the safety rope 10 on the other hand can be formed in certain areas from appropriate magnetic materials which can be detachably connected to each other.

[0078] The locking unit 34 can also include the extension-stop mechanism 34.2, which is designed, for example, to secure an unused length of the safety cable 10 against being pulled out while the lock 6 is engaged. For example, the extension-stop mechanism 34.2 can be designed as a locking hook or locking pin that engages directly in the safety cable 10, for example in a corresponding locking receptacle, to fix and hold it in the relevant extended position.
