Description

TECHNICAL FIELD

[0001] The invention relates to a latching device. BACKGROUND

[0002] Such a latching device serves to connect two components to one another. Such a latching device can be used, for example, to secure an object, such as a tool, on a superordinate component, such as a carrier device, a belt or strap, a ladder, a vehicle, a scaffold, etc.

[0003] Such a latching device has a first latching component which has a locking element, a force transmission element which is operatively connected to the locking element and which can be loaded in a force direction, and an operating element which is movable relative to the locking element. The latching device also comprises a second latching component which has an engagement element. The locking element and the engagement element can be coupled to one another and are connected to one another in a closed position in order to connect the first latching component and the second latching component to one another. In this case, in the closed position, when the force transmission element is loaded in the force direction, the locking element is loaded by the force action of the force transmission element in a locking direction towards a direction in which it abuts against the engagement element. The operating element is operable in order to adjust the locking element against the locking direction in order to release the connection between the locking element and the engagement element.

[0004] Such a latching device can achieve a particularly secure connection in that the locking element is secured in its connection with the engagement element by the force action on the force transmission element in that the force transmission element loads the locking element towards the direction in which it abuts against the engagement element. The connection between the latching components can be released by operating the operating element in order to thereby cause an adjustment of the locking element against the locking direction and thus away from the abutment against the engagement element.

[0005] From EP 3 093 525 B1 a device for holding a shackle formed in an elongate element is known, which has a base component, a carrier ring and a jaw which is radially movable relative to the carrier ring. At least one elastic element loads the jaw radially inwards, wherein the jaw engages form-fittingly into the base component in a pushed-in position when the shackle abuts on an end of the jaw radially outwards. A lever is axially adjustable relative to the base component and the carrier ring in order to press the jaw radially outwards and to release its form-fitting engagement into the base component.

[0006] From EP 2 475 278 B1 a latching device with two latching components is known, wherein the two latching components are held together in a closed state under load by a frictional fit by static friction or by a locking connection, wherein a magnetic mechanism serves to generate an attractive force between the latching components in order to magnetically assist the latching device in the transition into the closed state. SUMMARY

[0007] It is an object of the application to provide a closure device which is easy to close in the case of comfortable operation for opening the closure device and which can provide a secure connection between the closure parts in the closed position.

[0008] This object is achieved by a closure device according to the application.

[0009] According to this, in the closure device, the first closure part has a first magnet element and the second closure part has a second magnet element, wherein the first magnet element and the second magnet element magnetically interact jointly when the locking element and the engagement element are combined with one another.

[0010] In the closure device, a loadable connection between the closure parts is achieved in such a way that, on the side of the first closure part, a force transmission element is operatively connected with the locking element and, when a load is applied on the force transmission element, the locking element of the first closure part is fixed in its engagement with the engagement element of the second closure part. The load applied on the force transmission element thus results in a force acting at the locking element in the direction of the locking direction towards the abutment with the engagement element, so that the load applied on the force transmission element causes the locking element to remain engaged with the engagement element in a loadable manner.

[0011] The closing of the closure device can in this case take place in a comfortable manner in such a way that the combination of the locking element and the engagement element is magnetically assisted by the magnet elements of the closure parts. The magnet elements magnetically interact jointly, so that the combination of the locking element and the engagement element is magnetically assisted, so that the locking element and the engagement element are preferably at least as automatically as possible engaged with one another when the locking element and the engagement element are combined with one another.

[0012] Furthermore, the opening of the closure device can also take place comfortably and easily, in particular when the force transmission element is unloaded. For the opening, an operating element can be operated, which is operatively connected with the locking element, so that the locking element is adjusted against the adjustment direction when the operating element is operated. In this case, the locking element can be adjusted by the action of the operating element on the locking element. However, the adjustment of the locking element can also take place, for example, by a prestress on the locking element and / or an elasticity, whereas the operating element for this does not act directly on the locking element, so that in this case the operating element only achieves the resetting of the locking element from the closed position, but the resetting of the locking element takes place at least as automatically as possible, for example, due to the prestress on the locking element and / or the elasticity.

[0013] The operating element and the locking element can also be formed in one piece, for example, in the geometric shape according to the type of parallelogram, wherein the operation at one corner causes a change in the angle of the opposite angle, for example, opening. In this case, a section of the locking element is movable and operable relative to the operating element.

[0014] There can also be more than one locking element, which can be operated together via the operating element.

[0015] In one design variant, the force transmission element is formed by a tensile element, which can withstand tensile forces. The force transmission element can be designed, for example, to be flexible in such a way that it is formed, for example, by a rope, a belt, a strap, a drive belt or the like, so that in this case tensile forces can be transmitted via the force transmission element, while pressure cannot.

[0016] In one design variant, the force transmission element is implemented by a housing, which changes its position by the force action and thereby blocks the locking element. In this design variant, the additional force transmission element can be dispensed with.

[0017] The locking part of the locking device is associated with the assemblies, which are to be connected to one another via the locking device. In this case, one assembly is connected, for example, firmly to the second locking part, while the other assembly is connected to the first locking part, in particular to the force transmission element of the first locking part. If a force action between the assemblies occurs, this leads to a load being exerted at the force transmission element, so that the force action between the assemblies leads to a securing of the connection in such a way that a force action occurs at the locking element when a load is exerted at the force transmission element, so that the locking element remains in abutment with the engagement element.

[0018] In one design variant, the force transmission element has an action section, which extends at least section-wise circumferentially around the locking element. In particular, a force action can be induced radially inwards via the action section, so that the locking element is subjected to a force radially inwards towards the direction of abutment with the engagement element when a load is exerted on the force transmission element in the force direction.

[0019] If the force transmission element is formed by a flexible tensile element, the action section can be formed, for example, by a clasp, which is arranged on the locking element and is thereby in operative connection with the locking element, so that the locking element is subjected to a load radially inwards and thereby remains in engagement with the engagement element, which is engaged into the locking element, when a tensile load is exerted on the force transmission element.

[0020] In one design variant, the first locking part has a housing, in which the locking element is elastically adjustable relative to the housing. The locking element can have, for example, one or more legs, which are elastically adjustable in order to engage the locking element with the engagement element in order to close the locking device and to disengage the locking element from the engagement element in order to open the locking device. In this case, the locking element can be elastically pre-tensioned relative to the housing, for example, by being in elastic connection with the housing or by one or more spring elements, via which the locking element is elastically pre-tensioned relative to the housing. However, the locking element can also be designed to be elastic as such, so that, for example, the legs of the locking element are elastically adjustable relative to one another.

[0021] In one embodiment, the operating element is subjected to a force towards the non- operating position relative to the housing. This force can be caused, for example, by a mechanical spring element via which the operating element is spring- elastically preloaded relative to the housing. However, this force can also be caused, for example, magnetically in such a way that the operating element is loaded in the closed position of the locking device by a magnetic action towards the non-operating position.

[0022] The operating element is thus preloaded towards the non-operating position. After the operation, the operating element thus automatically returns into its non-operating position, so that the locking device can be reclosed by the locking components being coupled to one another in such a way that the locking element of the first locking component and the engagement element of the second locking component are coupled to one another and engage one another.

[0023] In one embodiment, a first magnet element is arranged on the operating element and is movable together with the operating element when the operating element is operated. By means of the magnetic interaction between the first magnet element on the operating element of the first locking component and the second magnet element on the engagement element of the second locking component, the locking components are magnetically attracted to one another when coupled to one another in order to close the locking device, so that the closure of the locking device is magnetically assisted. The first magnet element is arranged on the operating element, so that in this case the operating element can be moved simultaneously into its non-operating position, so that the locking element of the first locking component and the engagement element of the second locking component can be brought into engagement with one another in order to be able to couple the locking components to one another. If the operating element is moved in order to open the locking device, the magnet elements are also moved relative to one another, whereby the magnetic attraction between the magnet elements can be weakened, for example, so that the opening of the locking device is facilitated by uncoupling the locking device from one another.

[0024] In one embodiment, the locking element has an elastically deformable spring section and at least one leg arranged on the spring section, which can be brought into abutment with the engagement element. The locking element can have, for example, a U-shaped design with two legs which are coupled to one another via the spring section, wherein the legs can be elastically adjusted relative to one another in the event of an elastic deformation of the spring section in order to establish an engagement with the engagement element and also to uncouple the engagement with the engagement element again.

[0025] The force transmission element is preferably arranged on the at least one leg in this case, so that the force acts on the at least one leg when the force transmission element is loaded and the at least one leg is loaded in abutment with the engagement element in the locking direction.

[0026] If the force transmission element is formed, for example, as a flexible pulling element, for example, in the form of a cord, a belt, a strap, a drive belt or the like, a channel-like cord channel can be formed on at least one leg, for example, in which the force transmission element is arranged and via which an effective connection between the force transmission element and the at least one leg is established. Thus, upon application of a load at the force transmission element, a force acting in the direction of engagement with the engagement element is induced at the leg.

[0027] In one design variant, the operating element has an operating section which, upon operating the operating element, acts onto the at least one leg in order to adjust the at least one leg against the locking direction to release the connection between the locking element and the engagement element. In this case, the operating element directly acts onto the locking element in order to adjust the locking element to release the connection between the blocking parts and to disengage the locking element from the engagement element. The operating section can be formed, for example, in the manner of an inclined plane, such that upon operating the operating element the operating section strikes onto an associated section of the locking element, for example, on at least one leg of the locking element, in order to adjust the at least one leg against the locking direction.

[0028] The operating element can be operable along an operating direction which is oriented perpendicular to the locking direction. Due to the effective connection between the operating element and the locking element, a force deflection is induced, due to which, upon operating the operating element along the operating direction, the locking element is adjusted transversely to the operating direction, i.e. against the locking direction, in order to release the engagement between the locking element and the engagement element in this way and to be able to release the blocking parts from one another.

[0029] In one design variant, the locking element has a locking section which, in the closed position, engages form-fittingly with the engagement element. Thus, in the closed position, a form-fitting engagement between the locking element and the engagement element exists, such that the blocking parts are form-fittingly held together thereby. Upon application of a load at the force transmission element, the engagement is additionally ensured by the force acting onto the locking element, such that the blocking device cannot be opened, or at least not easily opened, when under load. Only upon unloading by operating the operating element, a (simple) opening of the blocking device is possible.

[0030] In order to unload the force transmission element, a handle can be arranged on the force transmission element, for example, which a user can hold onto in order to reduce the force introduction into the first blocking part via the force transmission element.

[0031] In another design, a frictional fit between the locking element and the engagement element can also be present in the closed position, in such a way that the associated frictional surfaces of the locking element and the engagement element force-fittingly abut one another. The frictional fit is ensured when a load is applied on the force transmission element in such a way that the locking element takes up the load in abutment with the engagement element.

[0032] In one design, the first locking part has a form-fitting element, for example in the form of a button or a pin, which prevents movement of the operating element, whereby the lock is not opened accidentally even without a load.

[0033] The system has, for example, a useful assembly and a lock according to the type described above. The useful assembly can be provided, for example, on the force transmission element, such that when a force is present on the useful assembly, the force introduces a load into the first locking part via the force transmission element, thereby ensuring the connection between the locking parts of the lock.

[0034] The useful assembly can be constituted, for example, by a tool, for example in the form of an electric tool, such as an electric screwdriver, a drill, etc., or in the form of a non-electric tool, such as a hammer, a wrench or pliers. Via the lock, the useful assembly can be fastened on a superior assembly, for example a carrier device, such as a ladder, a scaffold, a vehicle, etc., wherein the connection is ensured when a load is applied at the useful assembly and can be loosened when unloaded in order to separate the useful assembly from the superior assembly.

[0035] According to another aspect, the system has a useful assembly and a lock. The lock has a first locking part and a second locking part. The first locking part comprises a force transmission element, which can take up a load along a force direction, connected with the useful assembly, and a first magnet element. The second locking part comprises a second magnet element. The first locking part and the second locking part can be combined with one another, are connected with one another in a closed position and can be loosened from one another to open the lock. When the first locking part and the second locking part are combined with one another, the first magnet element and the second magnet element act together in a magnetically attractive manner. It is proposed here that the force transmission element has a shock-reducing section, which is deformable when a load is applied at the force transmission element.

[0036] The lock can be designed, in particular, according to the type described above, such that full reference is made to the explanations above for the advantages and advantageous design solutions.

[0037] The force transmission element can be constituted, in particular, as a pulling element for transmitting a pulling force, preferably exclusively. The force transmission element can be constituted, for example, flexibly, for example in the form of a rope, a belt, a strap, a drive belt, etc. Via the force transmission element, the useful assembly, for example a tool, can be connected with the first locking part, wherein the useful assembly can be fastened on a superior assembly via the lock in a loosable manner.

[0038] The impact-reducing section deformable upon application of a load at the force transmission element is especially capable of undergoing a change in length upon application of an impact load on the force transmission element. The impact-reducing section can for example have layers stitched to each other, wherein the stitches tear when an impact load is present that exceeds a limit force determined by the thickness of the stitches, so that the impact-reducing section becomes longer.

[0039] The impact-reducing section is especially capable of deforming plastically and irreversibly, especially by tearing the stitches plastically and irreversibly. Alternatively, the impact-reducing section can also be elastically deformable. BRIEF DESCRIPTION OF DRAWINGS

[0088] Figures 1 to 13A - 13D shows an embodiment of a locking device 1 having a first locking part 2 and a second locking part 3 and serving to connect two assemblies to one another. A first assembly is associated with the first locking part 2 in this case, while a second assembly is associated with the second locking part 3, such that the assemblies can be secured to one another by connecting the locking parts 2, 3 to one another.

[0089] The locking parts 2, 3 can be brought together along a closing direction X and held together in a closed position, such that the assemblies associated with the locking parts 2, 3 are connected to one another via the locking parts 2, 3. The first locking part 2 can be operated in order to loosen the connection between the locking parts 2, 3 and thereby separate the assemblies associated with the locking parts 2, 3 from one another.

[0090] In the embodiment shown, the first locking part 2 has a housing 20, which is formed by two housing parts 200, 201 that are brought together and firmly connected to one another to complete the housing 20.

[0091] The housing 20 encloses a locking element 24, which has a U-shaped profile in the embodiment shown, having two legs 244, 245 that are connected to one another via an elastic section 243 and are elastically adjustable relative to one another under elastic deformation of the elastic section 243.

[0092] An operating element 23 is also provided on the housing 20, which is movable on the housing 20 along an operating direction B opposite the closing direction X and is operatively connected to the locking element.

[0093] The housing part 201 forms an opening 202 on the front side, which opening is divided into two sections by a guide section 205 of the housing part 200, and via which an force transmission element 21 in the form of a soft pulling element is introduced into the housing 20, for example in the manner shown in the exploded view according to Figure 4 . A handle 210 is provided on the force transmission element 21, via which a user can grip the force transmission element 21. An assembly associated with the locking part 2 can be connected with the force transmission element 21, wherein such an assembly causes a (tensile) load on the locking part 2 in the force direction F (see for example Figure 7A ).

[0094] In order to connect the locking parts 2, 3 to one another, the engagement element 31 of the second locking part 3 can be inserted into an opening 204 at the bottom of the housing part 201 and engages with a locking section 241 which is formed by the inner edges of the legs 244, 245 in the region of the bottom 240 of the locking element 24, as can be seen for example from the views according to Figure 5A and 5B . In the closed position, the locking section 241 of the legs 244, 245 engages with the surrounding locking protrusion 310 at the head end of the pin-shaped engagement element 31 of the locking part 3 which is remote from the base 30, so that a form-fit connection between the locking parts 2, 3 is established via this.

[0095] The operating element 23 has a protruding section 230 on the inner side facing the locking element 24, which section projects out of the opening 203 on the upper side of the housing part 200 and carries operating sections 231 on sides which face away from one another, via which an active connection with the legs 244, 245 of the locking element 24 is established, as can be seen for example from Figure 5B in connection with Figure 6B . The locking section 241 is associated with one of the legs 244, 245 respectively and projects into the engagement opening 242 of the locking element 24, so that the operating sections 231, which are designed in the manner of inclined planes, collide on the edge sections on the legs 244, 245 in the region of the engagement opening 242 when the operating element 23 is operated in the operating direction B, so as to adjust the legs 244, 245 in the splaying direction A to splay the locking element 24, as can be seen for example from Figure 6B .

[0096] The force transmission element 21 forms an action section 211 in the form of a loop which surrounds the locking element 24, as can be seen for example from Figure 4 in connection with Figure 9D . Each leg 244, 245 of the locking element 24 has a channel-type cord groove 246 in this case, through which the force transmission element 21 extends. The action section 211 surrounds the resilient section 243 on the outside and as can be seen for example fromFigure 9D The two cord grooves 246, which extend through the legs 244, 245 and through the opening 202 in the housing 20, are seen in Fig. 2.

[0097] The locking device 1 has magnet elements 22, 32, one of which 22 is arranged on the section 230 of the operating element 23 and thus on the first locking part 2, and the other 32 is arranged on the engagement element 31 of the second locking part 3. The magnet elements 22, 32 interact in a magnetically attractive manner, such that the joining of the locking parts 2, 3 for closing the locking device 1 is magnetically assisted and the engagement element 31 of the locking part 3 is essentially automatically engaged with the locking element 24 of the locking part 2.

[0098] For closing the locking device, the locking parts 2, 3 can be joined to one another along a closing direction X, as seen in Figs. 1 and 2, such that the engagement element 31 is brought into abutment with the locking sections 241 of the legs 244, 245 at the opening 204 in the bottom of the housing 20 and the legs 244, 245 are spread apart from one another along a spreading direction A by impact onto the locking sections 241, such that the locking element 24 is widened and the engagement element 31 is snapped in an engaging manner with the legs 244, 245. Figures 7A-7D and 8A-8D, such that the engagement element 31 abuts against the locking sections 241 of the legs 244, 245 at the opening 204 in the bottom of the housing 20 and the legs 244, 245 are spread apart from one another along a spreading direction A by impact onto the locking sections 241, such that the locking element 24 is widened and the engagement element 31 is snapped in an engaging manner with the legs 244, 245.

[0099] In the closed position shown in Figs. 1 and 2, the locking sections 241 of the legs 244, 245 are engaged with the locking protrusions 310 of the engagement element 31 in the region of the bottom 240 of the locking element 24, such that a form-fit connection is established between the locking parts 2, 3. Figures 9A-9D The joining of the locking parts 2, 3 is in this case assisted in a magnetically attractive manner by the magnet elements 22, 32 of the locking parts 2, 3, such that the engagement is essentially automatically established.

[0100] The magnet element 22 is arranged on the section 230 of the operating element 23, so that the operating element 23 is loaded into a non-operating position upon closing, in which the operating element 23 in particular does not act onto the locking element 24 for spreading.

[0101] The guide sections 205, 206 are shaped on the housing part 201 of the housing 20, for example from

[0102] The joining Figure 4 is seen in Figs. 1 and 2. Upon joining of the locking parts 2, 3 to one another along the closing direction X, the engagement element 31 of the locking part 3 slides between the guide sections 205, 206 and is guided on the housing 20, such that an inclination of the locking parts to one another is counteracted upon joining. Figure 2B

[0103] ​If a load force is introduced into the force transmission element 21 in the closed position of the closure device 1 along the force direction F, i.e. corresponding to a tensile load on the force transmission element 21, the action sections 211 pull together in the form of a clasp and thereby adjust the legs 244, 245 of the locking element 24 radially inwards, as can be seen from Figures 10A-10D . Thereby, the locking sections 241 are pressed inside the legs 244, 245 into engagement with the locking protrusions 310 of the engagement element 31, so that a form-fit connection between the closure parts 2, 3 is ensured when a load is applied on the force transmission element 21, so that the closure parts 2, 3 cannot easily come loose from one another under load.

[0104] If the closure parts 2, 3 should come loose from one another, the force transmission element 21 needs to be unloaded. For this, no special action is required if no load force is acting on the force transmission element 21 along the force direction F. Without application of a load, the locking element 24 of the closure part 2 reaches a position according to Figures 9A-9D . In contrast thereto, if a load is acting on the force transmission element 21, the user can hold the handle 210 and pull it (slightly) towards the closure device 1 along the unloading direction L, so that the force transmission element 21 is thereby at least unloaded in the region of the closure device 1.

[0105] If the force transmission element 21, and thereby the locking element 24, is unloaded, i.e. corresponds to the position according to Figures 11A-11D , the user can hold the operating element 23 and adjust it relative to the housing 20 along the operating direction B, as can be seen in the transition from Figures 11A-11D to Figures 12A-12D . When operating the operating element 23, the operating sections 231 on the sections 230 collide with the legs 244, 245 of the locking element 24 and thereby spread the legs outwards along the spreading direction A, so that the engagement between the locking element 24 and the engagement element 31 is cancelled, in particular as can be seen from Figure 12C .

[0106] The closure parts 2, 3 can thereby be brought loose from one another as can be seen in Figures 13A-13D , wherein this can be carried out by operating the operating element 23 along the operating direction B, and thereby during the movement.

[0107] The magnet element 22 is arranged on the operating element 23, whereby when the operating element 23 is operated, the magnet element 22 is also moved away from the magnet element 32 on the engagement element 31 of the closure part 3, so that the magnetic attraction between the closure parts 2, 3 is weakened and the closure parts 2, 3 can be removed from one another with little force.

[0108] The closure device 1 is as already referred to according to Figures 1 to 13AThe embodiment of -13D described, for example, can be used to connect two components to each other, wherein one component is arranged on the force transmission element 21 and the other component is arranged on the base 30 of the locking part 3. The component associated with the locking part 3 can in this case be implemented by the strap 6, which is fastened on the base 30 via a fastening element in the form of a strap connection 300, as is schematically shown in Figure 1 .

[0109] In the example shown in Figure 14 , a component in the form of a tool 4 is connected, for example, with the force transmission element 21, which in the example shown consists of a soft pulling element in the form of a rope, a belt, a strap or a drive belt. In this case, the locking device 1 serves to secure the component in the form of the tool 4 and to secure the tool 4 on a superior component 5 in the form of a ladder. If the user N operating the tool 4 drops the tool 4, the tool 4 is secured at the ladder 5 via the locking device 1. If the user N wants to release the tool 4, the user can operate the locking device 1 to open and separate the locking parts 2, 3 in order to remove the tool 4.

[0110] When working and moving on a ladder or a scaffold, a change in the fastening between the user and the scaffold can be carried out quickly and thus safely.

[0111] The tool 4 can be implemented by an electric tool, for example a drill, an electric screwdriver, a saw, etc., or also by a non-electric tool, for example a hammer, a wrench or any other tool.

[0112] However, the components arranged on each other via the locking device 1 can also be of a completely different type, so that the use of the locking device 1 is not limited to tools. For example, the locking device 1 can also be used at sports equipment, at pets, for transporting goods or for locking flaps and doors.

[0113] As is shown in Figure 15 and 16 , a shock-reducing section 217 can be arranged on the force transmission element 21, which attenuates the impact when the component associated with the locking part 2 falls, in that a force-induced deformation, for example an elongation, can occur on the shock-reducing section 217, as is shown in the example according to Figure 15 or 16.

[0114] The force absorption can be carried out at the section 217 by tearing open the seam of the folded stitched belt layer, for example.

[0115] In the example shown in Figures 17A to 17CIn the embodiment shown in Figure 17A , the locking elements 24 of the locking member 2 engage the engagement elements 31 of the locking member 3, as is seen in Figure 17B . The force transmission element 21 is arranged around the locking elements 24 on the housing 20 of the locking member 2, such that when a load is applied on the force transmission element 21, the locking elements 24 are tensioned radially inwards and are pressed into engagement with the engagement elements 31, as is seen in

[0116] In the embodiment shown in Figures 17A to 17C , an operating element 23 in the form of a slide movable along an operating direction B is provided on the locking member 2, which slide is operatively connected to the locking elements 24. By moving the operating element 23 relative to the housing 20 of the locking member 2 along the operating direction B, the locking elements 24 can be opened, as is seen in the transition from Figures 17B to 17C , such that the connection between the locking members 2, 3 can be released (when the force transmission element 21 is unloaded).

[0117] In the embodiment according to Figures 17A to 17C , the locking members 2, 3 have magnet elements 22, 32 which magnetically assist the coupling of the locking members 2, 3. The magnet elements 22 are in this case provided on the housing 20 of the locking member 2, such that when coupled there is a magnetic attractive force between the engagement elements 31 of the locking member 3 and the housing 20 of the locking member 2.

[0118] In another embodiment, the magnet elements 22 can be moved along the operating direction B when the operating element 23 is operated, thus simplifying and, if necessary, magnetically assisting the ejection of the locking member 3.

[0119] In the embodiments shown in Figure 18 and 19A , the locking members 2, 3 are coupled to one another along a closing direction X, such that the engagement elements 31 of the locking member 3 engage the locking elements 24 of the locking member 2, as is seen in Figure 18 combination Figure 19A .

[0120] In the embodiments according to Figure 18 and 19A -19C, the locking elements 24 are constructed in the type of a U-shaped clamp having legs 244, 245 which are elastically connected to one another via a resilient section 243 and are enclosed in the housing 20 of the locking member 2.

[0121] In the embodiment shown, the force transmission element 21 is realized by means of a slider element which has a central recess 212 which extends around the locking element 24 and has protruding sections 213, 214 at the inner contour which point inwardly toward the locking element 24 to interact with the legs 244, 245 of the locking element 24.

[0122] On the force transmission element 21, a pulling element in the form of a cord, a belt, a strap or the like can be provided, on which an assembly, for example a tool, can be fastened.

[0123] The operating elements 23 are arranged on the housing 20 on end sides facing away from one another and constitute a means for acting on the force transmission element 21. The operating elements 23 can be arranged pivotably on the housing 20, for example, and can each be pressed with a ramp constituted at one end into the associated recess 215 on the outside of the force transmission element 21, so that the respective ramp 232 strikes on the associated striking ramp 216 in the region of the recess 215.

[0124] If the locking components 2, 3 are to be coupled to one another, the operating elements 23 are to be operated, for example, so that by the interaction of the operating elements 23 with the force transmission element 21, in particular the interaction of the ramps 232 with the striking ramps 216, the force transmission element 21 is moved in the housing 20 in the unloading direction L into the position shown in Figure 19A . This takes place against the pretensioning of a spring element 218 which is constituted as a compression spring, for example.

[0125] In the position shown in Figure 19A , the locking components 2, 3 can be coupled to one another so that the engagement elements 31 engage with the locking element 24, which is magnetically assisted by the magnetic attraction of the magnet elements 22, 32 of the locking components 2, 3. In the position shown in Figure 19A , the legs 244, 245 can in particular be avoided radially outwardly, so that the engagement elements 31 can be pushed between the legs 244, 245 and can engage form-fittingly with the legs 244, 245.

[0126] If the operating elements 23 are released and the force transmission element 21 is loaded in the force direction F, as shown in Figure 19B , the protruding sections 213, 214 on the inner contour of the force transmission element 21 strike on the associated protruding sections of the legs 244, 245, so that the legs 244, 245 are thereby loaded radially inwardly and are pressed to engage with the engagement elements 31. The connection between the locking components 2, 3 is thus ensured (in the case of the locking components 2, 3 being loaded against one another).

[0127] If the blocking components 2, 3 are to be loosened from one another again, the operating element 23 can be pressed into the housing 20 in the operating direction B, preferably with unloading of the force transmission element 21, so that the ramp 232 again impacts on the impact ramp 216 outside the force transmission element 21 in the region of the recess 215 and adjusts the force transmission element 21 in the unloading direction L. The force transmission element 21 thus reaches the position according to Figure 19A again. As a result of the elastic tensioning between the legs 244, 245 by the elastic section 243, the legs 244, 245 are seated radially outwards, so that the engagement element 31 can be removed from the region of the locking element 24.

[0128] The adjustment of the force transmission element 21 in the unloading direction L takes place against the pretensioning of the spring element 218. After the operation, the force transmission element 21 is automatically reset in the force direction F with an adjustment path, so that the force transmission element 21 is spring-preloaded towards its closed position.

[0129] The idea on which the application is based is not restricted to the above-described embodiments, but can also be implemented in a completely different way.

[0130] Locking devices of the type described can be used to connect very different components to one another.

[0131] The force transmission element does not necessarily have to be subjected to tension, but for example can also be subjected to pressure, wherein in this case the force transmission element needs to be designed to be pressure-resistant.

[0132] The locking element can have a U-shaped design, but this is not mandatory. The locking element can for example also be formed by a single locking section which is spring-preloaded elastically for example with respect to the housing of the associated blocking component.

[0133] The operating direction of the operating element can be oriented perpendicular to the force direction along which the force transmission element is loaded, but this is not mandatory. The operating direction can also be oriented obliquely or collinearly to the force direction.
