Description

The invention relates to a cap for a cap arrangement. The cap arrangement is provided for holding spring strips of a underspring. In particular, the cap arrangement is provided for a, in particular rollable, lath grid, wherein the spring strips can be regarded as laths of the lath grid. The underspring is provided for a frame of a bed or for a piece of furniture. The cap has a cap cavity. The cap cavity is provided in a base body. In addition, the cap comprises a support section for arranging the cap on a support of the furniture item or of the frame and a connecting section provided between the base body and the support section. The cap cavity is configured to receive the end of a spring strip. The invention also relates, in addition, to a cap arrangement with caps of the aforementioned type.Furthermore, the present invention also relates to a underspring system having a cap arrangement of the aforementioned type and to the cap arrangement having spring strips inserted. The invention also comprises a frame or a piece of furniture with a suspension under spring according to one of the aforementioned embodiments.For fastening spring strips of a suspension under spring to a piece of furniture or a frame, cap arrangements are usually used, which are fastened to the piece of furniture on opposite frames or to a frame on or to opposite frame parts. The spring strips engage with their front ends in each case in the cap cavity of the respective caps of the cap arrangement. This generally results in a secure mounting of the spring strips on the cap arrangements.It is a disadvantage of the known suspension systems comprising cap arrangements and spring strips that they have a comparatively complex structure. Thus, it is generally necessary to deliver or provide the entire underspring as a common component, in particular to a customer. This occupies a not inconsiderable storage capacity. In addition, it is a disadvantage of the known suspension systems that, given a corresponding load on the spring strips, it can easily occur that at least one end of a spring strip slips out of the cap cavity and the spring strip loses its function.To prevent this, various securing means within the cap cavity are known in the prior art. However, this requires a comparatively exact insertion of the spring strips into the cap and, moreover, a specially adapted shape of the spring strip which is to be inserted into the corresponding cap. Due to this complex structure of the securing devices, it is generally spaced apart from providing them in the cap cavities.It is now the object of the present invention to provide a cap for a cap arrangement and / or a cap arrangement as such, with which the aforementioned disadvantages are at least substantially avoided or at least substantially reduced.The aforementioned object is achieved for a cap of the aforementioned type by the features specified in claim 1.According to the invention, in a first alternative according to the invention, it is provided that the cap can be detachably connected to an adjacent cap via a fastening device in such a way that the distance between adjacent base bodies of adjacent caps and / or the distance between adjacent caps can be adjusted. This is associated with the advantage that the caps can be provided releasably from one another in a cap arrangement. If underspringing is provided to a customer or a third party, it is no longer necessary according to the invention to have the caps already connected to a coherent cap arrangement and / or the spring strips already connected to the caps.In particular, the caps can be provided separately from one another and also separately from the spring strips.By a detachable arrangement of the caps relative to each other, it is ensured that the entire underspringing can adapt itself optimally to different conditions or spatial conditions for the underspringing. Thus, in particular as required, the number of caps can be increased or reduced for a predetermined length, which is associated with a high flexibility for the customer.By providing the caps separately, it is also possible, in particular, to drastically reduce the bearing capacity for maintaining underspringing. The installation of a lower suspension is also substantially simplified, in particular wherein the spring strips and the caps can be connected to one another in a comparatively simple manner.Moreover, the change in the distance between the base bodies of the adjacent caps also ensures that they can be laid with a different number of caps, for example, at a radius, at an angle and / or at a curve to one another and / or adapted to the respective situation of use. The flexibility for the user who wishes to use the corresponding underspringing is thus significantly increasedAccording to an alternative embodiment of the present invention according to the second alternative according to the invention, which can be realized in particular together with the first alternative according to the invention, it is provided that the base body protrudes beyond the support section, in particular in the longitudinal direction of the spring strip. Such protrusion relates in particular to the installed state. Accordingly, the width of the base body running in the longitudinal direction of the spring strips, in particular the maximum width of the base body, can be greater than the width of the support section, in particular the minimum width of the support section. The support section and / or the base body can have a width that changes in the transverse direction (i.e. transversely, in particular orthogonally, to the longitudinal direction of the spring strips).The main body projecting beyond the cap cavity yields the substantial advantage when using the invention that an undesired slipping out of the spring strips from the cap cavity can be prevented even when the pressure on the spring strips is increased, in particular without further securing devices being required in the cap cavity. Thus, in particular, the tilting moment of the cap has been optimized with respect to the spring strips arranged in the cap cavity with a corresponding load of the spring strip.In addition, the caps can be laid on a substantially narrower frame or frame, since the bearing surface for the bearing section can be significantly reduced by the invention compared to caps known from practice.The invention now creates the possibility of significantly improving the cap with regard to its use and with regard to flexibility during installation.The following explanations regarding preferred embodiments can apply to the first and / or second alternative according to the invention:In a preferred embodiment of the present invention, the fastening device is designed in such a way that the adjacent caps are connected to one another in a form-fitting and / or force-fitting manner. The form-fitting and / or force-fitting connection is in particular releasable, as has already been explained at the beginning in connection with the first alternative according to the invention.In particular, a latching connection is provided, wherein the fastening device can have the latching connection between the adjacent caps. Locking the caps together preferably ensures that simple detachment of the caps connected together can be ensured, wherein the caps are arranged firmly and / or stably on one another in the connected state. This type of connection is particularly easy to lay and is associated with a low susceptibility to errors when laying the entire underspring.The fastening device preferably has at least one first fastening means and at least one second fastening means. The first fastening means can be associated with one cap and the second fastening means can be associated with an adjacent, different cap. Accordingly, it is understood that the first and the second fastening means are in particular formed complementary to each other and / or can cooperate with each other to realize a corresponding releasable connection. The first fastening means of the cap according to the invention is accordingly also configured in particular as a function of the second fastening means of the other cap to be arranged on this cap.In particular, the first and the second fastening means in the connected state bear against one another at least in regions and / or are in particular connected to one another and / or to one another. Preferably, the fastening means are directly adjacent to one another in the connected state. In this way, a defined fastening region for connecting the first and the second fastening means is preferably formed, as a result of which ease of installation can likewise be ensured.In a further, particularly preferred embodiment of the inventive concept, it is provided that the cap has both the first and the second fastening means. Accordingly, the cap can be connected in particular to two adjacent caps, wherein the respectively adjacent caps can each have fastening means of complementary design.In particular, the cap can be connectable at both end regions to a respective adjacent cap. In this way, a cap arrangement can be formed by the cap according to the invention, in particular by caps connected to one another and / or to one another.It is understood that, on the one hand, for underspringing and, on the other hand, in particular for enclosing the spring strips, a "cap chain" (i.e. caps connected to form a cap arrangement, in particular along a chain) or a cap arrangement of caps connected to one another can be provided for both end-face end regions of the spring strips. In this context, caps connected in or to "cap chains" can be referred to as a (common) cap arrangement.Particularly preferably, the first and / or second fastening means is / are each arranged at an end region of the support section. The fastening means can form the end-face ends or be spaced apart from these ends. In any case, the first and / or the second fastening means can / can be arranged in the respective end region (i.e. at mutually opposite end regions) of the support section and ensure a connection of the caps to one another in the region of the support section.It is understood that the fastening means can also be detachably connected to one another.Furthermore, in a further preferred embodiment of the invention, it is provided that the first and second fastening means are designed such that the fastening means can be connected to one another in different positions, in particular at a different distance, and / or that the caps can be connected at an angle to one another. Accordingly, an alignment of the caps with respect to one another which is not aligned can be ensured, such that the caps enclose in particular a radius with respect to one another. This also allows a placement, in particular for furniture, to be significantly improved, since the cap and also the underspringing can adapt to different profiles and / or specifications of the underspringing, in particular wherein the end faces of the spring strips do not have to be arranged in alignment.The possibility of connecting the fastening means in different positions also makes it possible to change the distance between the caps or the base bodies. If, for example, different numbers of spring strips are required over a predefined length, as required, in particular for changing the spring behavior of the underspringing, a corresponding adaptation can be effected by varying the distance of the caps / base bodies from one another, which is also made possible in particular by the fastening means being able to be connected to one another in different positions.Preferably, the first fastening means has at least one coupling element and the second fastening means has at least one counter-coupling element which can be coupled to and / or interacts with the first coupling element. In this context, it is understood that the coupling element can be formed complementary to the counter coupling element or vice versa. Finally, the coupling elements and the counter coupling elements enable a detachable connection of the fastening means to one another and provide a simple connection of the caps to one another in an efficient manner.Particularly preferably, a plurality of coupling elements and / or counter coupling elements of the respective fastening means are provided. Thus, the first fastening means can have at least two coupling elements and / or the second fastening means can have at least three counter coupling elements. The plurality of coupling elements and / or mating coupling elements can ensure, in particular, that the fastening means can be connected to one another in different positions. A variation of the distance of the base bodies of the adjacent caps from one another can be ensured in that a coupling element can be connected to other counter-coupling elements or vice versa.Preferably, it is provided that in the connected state, in particular two coupling elements are connected to two counter coupling elements. If in particular three counter coupling elements are provided and furthermore in the connected state two coupling elements are to be connected to in each case two counter coupling elements, then in particular two differently adjustable distances of the caps / base bodies to one another result. If necessary, however, in a further embodiment of two coupling elements, only one coupling element can be connected to a mating coupling element, which in turn can ensure in particular a laying of the caps in a radius or in an arc-section-shaped course. The plurality of coupling elements and the counter coupling elements can accordingly ensure in particular an adjustment of the distance and an increase of the flexibility when laying the caps.Furthermore, in a further preferred embodiment, it is provided that the coupling element is designed as a locking pin. The latching pin can also be referred to as a latching projection. The counter coupling element can in turn be designed as a latching opening, in particular wherein the latching pin is designed for, in particular releasable, latching with the latching opening. An interaction between the latching pin and the latching opening ensures a detachable connection of the fastening means to one another in a comparatively simple manner and, moreover, a provision of the cap arrangement in a manner which is friendly to the installation.Particularly preferably, the first and the second fastening means are arranged on opposite end faces and / or end face end regions of the support section, which is likewise particularly advantageous during installation, since the connection can thus be ensured at the outer regions of the caps.In a further preferred embodiment, it is provided that, in particular arranged on the first and / or the second fastening means, a cover section is provided for at least regionally covering the fastening device. In particular, the cover section is connected to the first and / or the second fastening means by a bendable connecting region, preferably a film hinge. Preferably, the connection is effected in such a way that the cover section can be folded over onto the fastening device. The cover with the cover section makes it possible that in particular a manipulation of the fastening device can be avoided in the connected state of the caps. Thus, in particular the first and second fastening means can be protected from an undesired influence. This is particularly advantageous if the caps or the cap arrangement is rolled up, preferably when using a rollable lath grid. In this case, in particular, the cover section also makes it possible to prevent undesired detachment of the fastening device when the caps are rolled, wherein the fastening device is protected by the cover section.Particularly preferably, the cover section has a securing projection, in particular a locking hook, for latching with the first and / or the second fastening means in the folded-over state.In a further preferred embodiment, it is provided that at least one bending point is located between the first and / or the second fastening means and the connecting section. This bending point is particularly useful when the caps connected to one another, in particular the cap arrangement, are to be rolled up, preferably when used as a rollable slat grid. The bending point enables in particular a simple bending in this region and thus a rolling of a slat grid. The bending point is in particular designed as a material constriction or thinning of the support section. In particular, the bending point is arranged on and / or in the support section.If necessary, the bending point, which can also be referred to as the flexibility range, can also be used as a specification for a separating point. This is particularly useful when the side on which the bending point is arranged is not to be connected to another cap. The bending point can then enable a simple specification for removing the first and / or the second fastening means, wherein, if necessary, a severing can take place at the bending point by means of scissors or the like.In addition, the width, in particular the minimum width, of the bearing section in the longitudinal direction of the spring strips can be less than the width, in particular the maximum width, of the base body, preferably at least 20%, further preferably at least 30%, in particular at least 40%.Furthermore, the, in particular minimum, width of the first and / or second fastening means in the longitudinal direction of the spring strips can likewise be less than the, in particular maximum, width of the base body, in particular less by at least 20%, preferably less by at least 30%, more preferably between 35% and 80% less.Particularly preferably, the, in particular minimum, width of the first and / or of the second fastening means and / or the width of the support section is between 10 and 40 mm, preferably between 12-35 mm, particularly preferably between 15-30 mm. In particular, the, in particular minimum, width of the first and / or of the second fastening means is 25 mm + / - 20%.In a particularly preferred embodiment, the connecting section is designed at least in regions as a spring section. The connecting section is in particular connected to a central section of the support section, which is preferably arranged between the first and second fastening means.In particular, the connecting portion has resilient properties. Such a configuration of the connecting section is associated with the advantage that, when the caps are used in underspringing, spring behavior can already be ensured via the cap as such. In addition to the spring strips which are arranged in the cap cavities, the caps can thus also ensure damping or springing in the case of use. Overall, the spring properties of the entire underspringing can thus be improved.In a further and particularly preferred embodiment of the present inventive idea, it is provided that the first and / or the second fastening means has a recessed portion for at least regional support of the second or first fastening means to be arranged thereon. In particular, at least one fastening means can have a recessed portion which can ultimately also define a region for the arrangement of the other fastening means, as a result of which in particular the assembly can be simplified. In further embodiments, it can also be provided that the fastening means on the mutually facing surfaces in the installed state each have a recessed portion. Thus, in particular, the first fastening means on the upper side and the second fastening means on the lower side can have a recessed portion for arrangement. Furthermore, in further embodiments, it can be provided that at least the first fastening means or the second fastening means has a recessed portion on the upper side for the support of the second fastening means.In particular, the cap cavity is designed for the play-free, in particular form-fitting, arrangement of a spring strip. In this case, the spring strip can be enclosed in particular firmly in the cap cavity. For fastening the spring strip, in particular the end face of the spring strip, in particular no securing projections or the like are required in the cap cavity. Fastening is achieved in particular by inserting the end face of the spring strip into the cap cavity. The cap cavity can consequently have a receptacle which is designed to correspond to the outer cross section of the spring strip, in particular with minimal play, preferably less than 1 mm. Accordingly, the cap cavity can particularly preferably be formed corresponding to the cross section of the spring strip.The spring strip in turn can have, in particular, a fiber core and a jacket surrounding the fiber core, in particular made of a thermoplastic material. From the jacket, in particular on opposite sides, a strip leg can project laterally in each case, preferably made of a thermoplastic material. The resilient properties of the underspringing can thus be ensured via the spring strip. The fiber core can be provided in particular for absorbing and dissipating the forces, wherein the jacket and the strip legs can improve the resilient properties of the entire underspringing. Accordingly, the cap cavity can be designed in particular for receiving a section of the fiber core, the sheath and the strip legs. The inner shape of the cap cavity can thus be formed in particular corresponding to the outer cross section of the end face end of the spring strip.In a further preferred embodiment, it can be provided that the base body has at least one opening for the outflow of cleaning liquid. This opening is then facing away from the receiving opening for the arrangement of the spring strip. Particularly preferably, the at least one opening is arranged on the rear side of the base body facing away from the spring strip. In particular, a plurality of openings can also be provided. The openings can serve the purpose that, when the cap arrangement or the cap is cleaned and some cleaning liquid penetrates into the interior of the cap, this cleaning liquid can then correspondingly drain off. This allows easy handling of the cap and cap assembly and easy cleaning of the cap.Furthermore, the present invention also relates to a cap arrangement for holding spring strips of a suspension support for a piece of furniture or a frame. The cap arrangement according to the invention has at least two caps according to one of the aforementioned embodiments, each having a cap cavity. The caps are each designed to receive the end of a spring strip, in particular the end-side end of the spring strip, into the cap cavity. Preferably, adjacent caps are each detachably connected via a fastening device.In this context, it is understood that with regard to preferred embodiments and / or advantages of the cap arrangement, reference may also be made in the same way to the aforementioned explanations relating to the cap. These embodiments will not be reproduced again below in order to avoid unnecessary repetitions. It is also understood that the explanations for the cap arrangement can also apply to the cap without this requiring a further explicit explanation.It is understood in particular that the cap arrangement is composed of caps connected to one another. Thus, in particular two cap arrangements can be provided for each or each underspringing for the respective front-side ends of the spring strips. The cap arrangement accordingly represents in particular the caps in the connected state. The caps can be detachably connected to each other, so that, if necessary, the shape of the cap arrangement or the number of caps in a cap arrangement can also be changed.In the particularly preferred embodiment, an adapter piece is provided for enlarging the distance of adjacent base bodies of adjacent caps and for arrangement between two adjacent caps. The adapter piece can be designed in particular corresponding to the cap, but in particular can have neither a base body nor a connecting section.The adapter piece can accordingly in particular have a support section preferably with first and second fastening means provided on one side.Alternatively or additionally, it can also be provided that the adapter piece has the first and the second fastening means, but no bearing section. The adapter piece can be formed with a cover section or without a cover section. The support section can also be optionally provided. In any case, the adapter piece is formed without a base body and without a connecting section.The adapter piece can be designed to increase the distance between adjacent base bodies of adjacent caps.The adapter piece can be arranged on the fastening means of one cap and ultimately bridge the distance from the adjacent other cap. If, for example, a cap has a first fastening means which is to be connected to a second fastening means of another cap, the adapter piece can likewise have a first and second fastening means, such that the second fastening means of the adapter piece can be connected to the first fastening means of the one cap and the first fastening means of the adapter piece can be connected to the second fastening means of the other cap.By means of the adapter piece, in addition to the change of the positions of the caps with respect to one another, a further possibility can be created of changing or increasing the distance of the spring strips even further, as required, in the installed state. This is of interest in particular for furniture which frequently have different shapes than the rectangular shape of beds and there are other requirements for underspringing.The present invention also relates to a cushioning device, in particular a preferably rollable slat grid, having at least one cap arrangement according to one of the aforementioned embodiments, in particular two cap arrangements, and at least two slats. A respective spring strip is inserted into a cap cavity of a cap of the cap arrangement. In particular, both end-face ends of the spring strips are each inserted into a cap cavity of a cap of the respective cap arrangement. Accordingly, the underspringing can be composed of the caps connected to one another to form a cap arrangement in each case and the spring strips inserted in the caps.It is understood that with regard to advantages and / or preferred embodiments of the underspringing according to the invention, reference may also be made in the same way to the aforementioned explanations relating to the cap according to the invention and / or to the cap arrangement according to the invention, without this requiring a further explanation in this respect. In addition, the explanations relating to the underspringing also apply in the same way to the cap and / or the cap arrangement, without this likewise requiring a further explanation in this respect.The spring strips used in the underspringing can have, in particular, a fiber core and a sheath, preferably made of a thermoplastic, surrounding the fiber core. On opposite sides, a strip leg, preferably made of a thermoplastic material, can project laterally from the jacket. Such a construction of the spring strips is particularly advantageous with regard to the resilient properties of the spring strips. The fiber core is designed to conduct away the forces that have occurred in the state of use. The jacket and the strip legs can additionally ensure the resilient properties and further optimize them. In addition, in particular a cost-effective spring strip can be provided, since the material of the strip legs and / or of the sheath can differ from the cost-intensive material of the fiber core.In addition, in a further preferred embodiment, it is provided that the first and / or second fastening means protrudes or protrudes beyond the respectively adjacent strip leg and / or the respective base body at least in regions in the transverse direction, i.e. in particular orthogonally and / or transversely to the longitudinal direction of the spring strip. A protrusion of the aforementioned type is to be understood such that the region of the base body in which the strip leg is arranged is set back with respect to the respective fastening means or the respective fastening means protrudes in the transverse direction with respect to that portion of the base body which serves to receive the strip legs. In this way, in particular a distance between adjacent strip legs of adjacent spring strips can be ensured by a distance of adjacent base bodies of adjacent caps. Moreover, the protrusion ensures that adjacent caps can be easily connected to each other.In addition, the present invention also relates to a frame, in particular for a bed, having a suspension element according to one of the aforementioned embodiments.It is understood that with regard to embodiments relating to the frame-in particular with regard to embodiments relating to preferred embodiments and / or advantages of the frame according to the invention-reference may also be made to the aforementioned embodiments relating to the cap according to the invention, to the cap arrangement according to the invention and to the underspringing according to the invention, which may also apply in the same way to the frame according to the invention without this requiring any further explicit explanation.Finally, the present invention also relates to a piece of furniture with a suspension under spring according to one of the aforementioned embodiments and / or with a frame according to one of the aforementioned embodiments.In this context, it is to be understood that, with regard to advantages and preferred embodiments of the piece of furniture, reference may be made to the aforementioned explanations relating to the cap according to the invention, the cap arrangement according to the invention, the underspringing according to the invention and to the frame according to the invention. These statements are hereby expressly incorporated by reference.Furthermore, it is expressly pointed out that all the aforementioned and following intervals contain all the intermediate intervals and also individual values contained therein and these intermediate intervals and individual values are to be regarded as essential to the invention, even if these intermediate intervals or individual values are not specifically specified in detail.Further features, advantages and possible applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing and the drawing itself.

A cap assembly 2 may be formed by interconnected caps 1. Such a cap arrangement 2 is schematically illustrated in FIG. 8. Two cap arrangements 2 for a subspring 4 are shown in Figures 6 and 7.The cap arrangement 2 is provided for holding spring strips 3 of a subspring 4. Such spring strips 3, which are in particular each mounted with their front ends in the cap 1, are illustrated, for example, in FIGS. 6 and 7.In particular, a lath grid, namely preferably a rollable lath grid, is provided as underspring 4.The underspring 4 is provided in particular for a frame 6 of a bed 7 or for a piece of furniture 5. A bed 7 is schematically shown in Fig. 12 and a furniture item 5 is schematically shown in Fig. 11.As FIG. 1 shows, the cap 1 comprises a base body 9. Furthermore, the cap 1 comprises a support section 10, which serves for arranging the cap 1 on a support of the furniture 5 or of the frame 6. Thus, the support section 10 can be arranged in particular directly on a lower support surface. In addition to the support section 10, the cap 1 also comprises a connecting section 11 which is provided between the base body 9 and the support section 10 and in particular connects the base body 9 to the support section 10, as FIG. 2 shows schematically. The cap cavity 8 is designed to receive the end, in particular the end face end, of a spring strip 3. The inner shape of the cap cavity 8 can be designed to correspond to the outer cross section of the end of the spring strip 3, so that the end of the spring strip 3 can be arranged in the cap cavity 8 in particular in a form-fitting and / or substantially free of play.The cap 1 shown in FIG. 1 can be detachably connected to an adjacent cap 1 via a fastening device 12 in such a way that the distance 13 between adjacent base bodies 9 of the adjacent caps 1 can be adjusted. The spacing 13 of adjacent base bodies 9 is shown schematically in FIG. 6.It is understood that the fastening device 12 is ultimately formed not only by one cap 1, but by two caps 1. Two caps 1 arranged on one another can thus form the fastening device 12.Alternatively or additionally, it can also be provided that the base body 9 protrudes beyond the support section 10, namely in particular in the longitudinal direction of the spring strip 3 in the connected state. In the embodiment shown in FIG. 1, both are provided, namely the base body 9 projects beyond the bearing section 10, wherein at the same time the cap 1 is also formed in such a way that it can be connected to an adjacent cap 1 via a fastening device 12. This is schematically shown, among other things, in FIG. 6.The fastening device 12 can be configured such that adjacent caps 1 are connected to one another in a form-fitting and / or force-fitting manner. In the embodiments shown, a latching connection is provided between the adjacent caps 1 for the fastening device 12. Adjacent caps 1 can thus be locked to one another.The fastening device 12 can have at least one first fastening means 14 and at least one second fastening means 15. The first fastening means 14 can be provided on one cap 1 and the second fastening means 15 on the adjacent, other cap 1. In particular, the first and the second fastening means 14, 15 abut each other at least in regions in the connected state. This is illustrated in detail view A in FIG. 8, which likewise shows the corresponding detail A in enlarged form.It is therefore understood that a cap 1 has at least the first or the second fastening means 14, 15. The fastening means 14, 15 are now provided for the purpose that the fastening device 12 can be formed.In FIGS. 2 and 3 it is shown that the cap 1 has both the first and the second fastening means 14, 15. In this way, it is possible for the cap 1 to be connectable at both end regions to in each case one adjacent cap 1, this being illustrated schematically in FIG. 8. Accordingly, although a cap 1 does not comprise all parts of a fastening device 12, a cap 1 comprises either at least the first or the second fastening means 14, 15, preferably both fastening means 14, 15, so that this cap 1 can form the corresponding fastening device 12 when connected to another cap 1.FIG. 2 further shows that the first and the second fastening means 14, 15 are each arranged on an end region of the support section 10. Between the fastening means 14, 15 a central portion of the support portion 10 can be provided, which is connected to the connecting portion 11.FIG. 1 shows that the first fastening means 14 has at least one coupling element 16 and the second fastening means 15 has at least one counter-coupling element 17 which can be coupled to and / or interacts with the first coupling element 16. The counter coupling element 17 can be designed in particular to be complementary to the coupling element 16.
