description

introduction

[01] The present application relates to a joint bridging device for

Bridging a gap between two structural parts of a building, the

Joint bridging device comprising

two elongated side profiles, each in force transmitting manner connected to one of the building parts and parallel to the joint

extend

- At least one cover, which runs parallel to the side profiles and cooperates with the side profiles such that the covering covers the joint, and

a plurality of anchoring profiles, one anchoring profile in each case being connected in a force-transmitting manner to both side profiles,

wherein the cover means is connected to a plurality of the anchoring profiles, whereby at least one indirect force transmitting connection between the

Covering and the side profiles is created, wherein a length of each of the anchoring profiles exceeds a width of the joint, wherein longitudinal axes of the

Anchoring profiles are rotated with respect to longitudinal axes of the side profiles, wherein each of the anchoring profiles has at least two hinge devices and each one hinge means of an anchoring profile is assigned to one of the side profiles, wherein by means of the hinge means a respective anchoring profile relative to the

Side profiles is rotatable.

[02] Furthermore, the application relates to a method for assembling such

Joint bridging facility.

[03] The covering device can in particular be coupled to the side profiles exclusively by means of the connection described with the anchoring profiles. A beyond this connection between the covering and the side profiles is not necessary in such a configuration. This is particularly advantageous if the joint bridging device is to be used as an earthquake profile. The rotations of the longitudinal axes of the anchoring profiles relative to the longitudinal axes of the side profiles is typically in relation to an axis of rotation which extends perpendicular to a surface of the cover device. That is, the anchoring profiles, typically independent of their rotational position relative to the side profiles, are all in a common plane that is parallel to the surface of the cover. The "oblique" arrangement of the anchoring profiles relative to the side profiles serves to ensure that the anchoring profiles to a certain extent have a reserve of length, so that they can accommodate a movement of adjacent to the joint building parts to each other.This is particularly advantageous if the joint bridging device as an earthquake profile should be used.

[05] The hinge devices described serve equally to accommodate movements of the building parts, which due to the joint means no

Bending moments are introduced into the anchoring profiles. Instead, these can be free about a respective axis of rotation relative to the side profiles and thus to the

Rotate building parts and, for example, in the case of an earthquake, a movement of the building parts relative to each other. It is understood that the axis of rotation of a respective hinge device preferably perpendicular to a surface of the

Covering device is oriented.

PRIOR ART [06] Joint profile devices of the type described in the introduction are already known in the prior art. They typically serve as a so-called seismic profile, which is capable of receiving relative movements between adjacent building parts separated by a joint. In other words, these joint profile devices are not dependent on a fixed distance between the building parts, but can react to a relative movement of the building parts to each other. Thus, these Fugenprofileinrichtungen remain intact in the event of an earthquake on the respective building and often take no damage.

[07] For example, the International Patent Application WO 2015/120993 A1 discloses a joint profile device of the type described in the introduction. The side profiles shown there serve to delimit a respective floor covering against the joint, for which purpose the

Side profiles have an upright leg. In a joint region which extends between the side profiles, the associated joint is bridged by means of a plate-shaped covering device. This covering device is according to the cited

Document associated with a plurality of anchoring profiles, wherein by effect a spring is given a possibility for relative movement between the covering device and the anchoring profile. This ensures that, in the event of an earthquake, the covering device can to a certain extent carry out a compensation movement which prevents damage to the joint profile device as a whole. Furthermore, the anchoring profiles are installed at an angle, so that they can accommodate a widening of the bridged joint.

[08] The disadvantage of known joint bridging devices, as shown for example in said document, consists in the very complex and

cumbersome installation of the same. In particular, it is usually necessary to access the anchoring profiles, while at the same time the covering already covers the joint. In order to still have access to the joint space between the building parts despite the covering of the covering, it is a typical procedure to support the cover at least on one side by means of a wedge so that a free space remains, through which a person installing the joint bridging device under the cover can reach into the joint space. It is understood that this procedure can be cumbersome, uncomfortable and tedious.

[09] DE 10 2009 052 460 A1 discloses a covering device for bridging a joint between two structural parts of a bridge, which on the one hand has a

Height displacement of adjacent components and on the other hand a secure

Ensuring drainage from the road surface. The well-known

Covering device comprises a covering element in the form of a tear sheet, which has a width which exceeds a maximum width of the joint. The tear plate is arranged on two located at one end of the joint support plates, each support plate is in turn positioned on four sliding cam, which lie on both sides of the joint on the building.

task

It is an object of the present application to provide a joint bridging device and a method for their assembly, which is simplified compared to the prior art. solution

[11] The underlying task is based on the

Joint bridging device of the type described above according to the invention achieved in that the covering of a plurality of elongated rungs and at least one cover plate is formed. The rungs each extend between the side profiles and thus effectively bridge the gap. However, a plurality of pairs of rungs, each formed by two adjacent rungs, have a free space between the associated rungs. Advantageously, there is such a space between all adjacent rungs. This free space extends in a direction parallel to the longitudinal axis of the joint or the side profiles, wherein advantageously the rungs are oriented perpendicular to the longitudinal axis. It is therefore understood that the rungs form only a dissolved, in particular ladder-shaped, structure, which does not completely close the joint. This makes it possible to use said free spaces in the course of assembly of the cover by an access to a bottom of the cover, in particular access to the

Anchoring profiles, without further through the open spaces is possible. For completely closing or covering the joint, the covering device has said cover plate, which is placed on a side facing away from the joint top of the rungs and at least with a plurality of the rungs, preferably with all the rungs, in force transmitting manner is connected. It is understood that advantageously the cover plate is only installed when the rest of the cover device is completely assembled. This may be, for example, to connect at least a plurality of rungs in force transmitting manner each an anchoring profile. The covering device furthermore has at least two elongated edge profiles which run along mutually opposite edges of the cover plate and are each assigned to one of the side profiles. If the edge profiles lie directly against the cover plate, the edge profiles can be regarded as a kind of extension of the cover plate, which

can advantageously come to rest on their assigned side profiles. Depending on the design of the edge profiles, a seamless bridging of the joint can be created.

[12] The rungs may be in particular elongate flat steels which extend from one side profile to the other side profile. The cover plate may have various shapes, with usually a thin metallic plate (eg aluminum composite plate) or a plastic plate is suitable. However, it is also conceivable to carry out in the sense of an adaptation of the covering device to the adjacent floor of the building parts, the cover plate in a particular design or a specific material. The essential function of the cover plate is to cover the joint, so that between the rungs extending free spaces are covered. [13] The joint bridging device according to the invention has many advantages. On the one hand, it is obvious from the above description that the installation of the joint bridging device according to the invention is considerably easier than in the prior art. Thus, it is no longer necessary to access in the course of the installation from one side under the continuous cover, with both a narrow gap is available as well as poor visibility and the available mounting space are small. Instead, the cover can be successively mounted in parts, wherein the ultimately the joint covering element is initially retained in the form of the cover, while using the described spaces between the rungs, the connection of the cover with the

Anchoring profiles can be made completely easily. The free space forming clear distance between juxtaposed rungs

advantageously chosen so large that they provide sufficient space to allow a penetration with one or both hands. Overall, the assembly of the joint bridging device according to the invention by the aforementioned is both simplified and considerably accelerated.

In an advantageous embodiment, the covering device is connected at least to a plurality of the anchoring profiles in each case by means of a connecting means.

This connecting means can be embodied in particular in the form of a bolt, which is guided through a corresponding recess of a rung through into a corresponding receptacle on the respective reinforcing profile. It is important that the respective connecting means engages with the associated anchoring profile, so that an axis of rotation of the anchoring profile coincides in the course of a movement of the building parts relative to each other with a longitudinal axis of the connecting means. In other words, it is advantageous if the anchoring profiles about the longitudinal axis of the

Turn connecting means. As a result, a twist of the

Reinforcing profiles is possible without causing a movement of the cover is caused. Furthermore, the central positioning of the connecting means is advantageous in that the covering device can be centered on the joint bridging device as a whole by means of the connecting means.

[15] At least a majority of the connecting means, preferably all

Connecting means also advantageously cooperate in each case with a spring, by means of which the cover and a respective reinforcing profile can be clamped together. The spring represents insofar as it were a flexible fixation of the cover to the reinforcing profiles, which is a relative movement of the both parts allowed each other in the event of a force. This would not be the case in the case of a rigid connection, for example by means of a screw connection. The spring thus makes it possible, for example, in the case of an earthquake, for the covering device to be pushed away from the respective reinforcing profile. As a result, an uncontrolled weakening or breaking of the covering device in the event of exposure to an earthquake is avoided and also prevents damage to the covering device. For the purposes of the present application, a "spring" is understood to be any type of elastic force transmission means., Not only are conventional springs suitable as "springs" within the meaning of the present application, but also, for example, elastically formed plastic elements which are elastically compressible, snap rings and the like more. Crucial here is only the spring action of the particular agent used.

[16] Using the covering device according to the invention, it is furthermore of particular advantage if in each case a connecting means with a rung of the

Cover device cooperates. It follows that the force-transmitting

Connection between the cover and the anchoring profiles by means

Connections between the rungs and the anchoring profiles is made. The cover plate of the covering device as such is then not involved in this connection. Advantageously, the cover plate is placed on the rungs only after the connection of the respective rungs with the associated reinforcing profiles, so that the connecting means are optically covered. This procedure is also of particular advantage insofar as with the cover of the joint by means of the cover plate easy access to the joint itself is prevented by the spaces between the rungs through. Consequently, it makes sense to connect the cover with the

Anchoring profiles at the time of application of the cover already

to have completed.

[17] In an advantageous embodiment of the invention

Fugenüberbrückungseinrichtung act both the rungs and the cover of the cover directly together with the edge profiles, while the edge profiles as such rest directly on the side profiles. Thus, the edge profiles form

as it were a link between the rungs or the cover plate and the side profiles. This is of particular advantage insofar as the edge profiles can be particularly easily adapted to the geometry of the respective side profiles used, so that regardless of the specific configuration of the respective

Joint bridging device the rungs and the cover plate basically one maintain the same structure. In principle, it is also conceivable that a plurality of edge profiles are used, each extending only in sections along an associated side profile. Each edge profile acts advantageously together with at least two rungs. [18] In terms of a particularly simple assembly, the edge profiles are also advantageous insofar as they somehow loose a link between the individual, in itself

Forming sprouts. Thus, it is understood that, in principle, the sprouts are detached from each other due to their distance from each other, so they would have to be placed individually on the side profiles and mounted on these without the use of the described edge profiles. The edge profiles make it possible to couple the rungs already apart from each assembly site of the joint bridging means together and finally hang as a whole (without the cover plate) on the joint. Thus, the rungs are already in a fixed position, so that the connection of the same can be started with the respective associated reinforcement profiles. The cover plate, which in turn is installed later, can then be connected in a particularly simple manner directly to the rungs, for example by means of a bond. A

Bonding has the advantage that the construction below the cover plate is invisible. Furthermore, the attachment of the cover plate by means of bonding as such is also not visible, which has a visually positive effect. It is thus possible the

Overall, the joint bridging device optically adapted to the adjacent floor covering in such a way that the joint bridging device is very inconspicuous and can only be perceived on closer inspection. This is desired in numerous applications.

[19] The joint bridging device according to the invention is then also advantageous if at least one of the anchoring profiles has at its opposite ends in each case a coupling element by means of which the anchoring profile can be connected in force-transmitting manner to the side profiles. This connection is preferably carried out by means of a positive connection, which is formed between the side profiles and the coupling elements.

[20] Using the coupling elements, it is also advantageous if in each case a joint device of an anchoring profile is formed on each one of the coupling elements. In this way, the coupling elements can take over two functions, namely on the one hand the connection of the anchoring profiles with the

Side profiles as well as the rotatability of the anchoring profiles relative to the

Side profiles. It is understood that the anchoring profiles only in the scope of a central element that extends between the coupling elements, relative to the Side profiles twisted while the coupling elements remain rigidly connected to the respective associated side profile.

[21] Ideally, a respective coupling element comprises two action sections, wherein the first action section is adapted to engage with a side profile, while in the second action section the hinge device is arranged. In this way, the functions "attachment" and "hinge device" on the coupling element are equalized.

[22] Advantageously, the joint device in the form of a fork is formed on a respective coupling element, which has two opposing flanges, which together define a gap between them. This space is advantageously dimensioned so that it is suitable for receiving an end portion of a respective central element of an anchoring profile. Said end portion can enter accordingly in said space and there by means of a

rotationally symmetrical connecting means, in particular by means of a bolt, are fastened, wherein a rotatability of the central element is maintained relative to the hinge means about the longitudinal axis of the connecting means.

Furthermore, it may be advantageous if the coupling elements each one

Have engagement portion which is C-shaped, wherein two arcuate flanges of the same diameter partially surround a circular gap. Such engagement portion may be to form a positive connection with a

engage circular spring of the respective associated side profile form fit and create a force-transmitting connection in this way. It is particularly advantageous to assess that a certain range of motion of the coupling element formed in this way is maintained relative to the associated side profile, since the coupling element can rotate about an axis of rotation which extends parallel to a longitudinal axis of the spring, at least in a certain amount of play , As a result, at least load peaks due to earthquake-induced movement of the

Structural parts are intercepted relative to each other. An exemplary embodiment of the construction described results from the embodiments below. [24] In terms of process technology, the underlying object is achieved according to the invention by means of the following method steps:

The side profiles are each in force with one of the structural parts

communicatively connected. The anchoring profiles are connected to the side profiles.

At least the rungs of the cover are placed at least indirectly on the side profiles, wherein at least between a plurality

adjacent rungs each leave a free space that is located in

extends longitudinal axis parallel direction to the side profiles.

At least a majority of the sprouts is each with a

Anchoring profile connected.

The cover plate is connected to the rest of the cover, so that the covering finally finally covers the joint. Of importance here is that the said process steps need not necessarily be carried out in the order presented here. Thus, in particular two different variants are conceivable.

The former includes a connection of the anchoring profiles with the side profiles before the cover is placed on the joint. In this variant, after placing the covering in the form of sprouts, that is, first without the cover plate, the sprouts, or at least a part thereof, are connected to respectively associated anchoring profiles. The free space extending between adjacent rungs can thus be used to connect at least some of the rungs, preferably all rungs, with associated anchoring profiles. Due to the free space, it is possible that it can be used by the same in the joint area - ie in an area below the rungs, which the

Step greatly facilitates the connection between rungs and anchoring profiles. After completion of this process step then the

Installed cover in which this is preferably placed on the rungs and connected to these.

In contrast, the second variant is designed so that the individual rungs already in advance of the launch of the covering on the joint or the side profiles with the anchoring profiles or at least a part thereof (in particular a

Middle element). In this procedure, the anchoring profiles must be placed before placing the cover (without the cover plate) on the joint in a rotational position in which they do not collide with the side profiles. Consequently, the anchoring profiles can be inserted in the said rotational position in the joint between the building parts. Once the cover together with the

Anchoring profiles is installed, the anchoring profiles can each be attached to the Side profiles are connected. For this purpose, it is conceivable, for example, that the side profiles are already equipped with coupling elements and the anchoring profiles only need to be connected to the coupling elements. For this

Mounting step are the between each adjacent rungs extending spaces according to the invention of particular advantage. After connecting the anchoring profiles to the side profiles, finally, the cover plate can be placed and connected in force transmitting manner with the rest of the cover.

Perhaps other sequences of assembly steps are conceivable, which are not mentioned here. However, this is irrelevant to the success of the invention, since the latter largely results from the particularly easy access to the joint space extending between the joints, which is made possible due to the spaces between adjacent rungs of the still unfinished covering.

embodiments

[25] The joint profile device according to the invention and the method according to the invention are explained in more detail below with reference to an exemplary embodiment, which is illustrated in the figures. It shows:

1 shows a cross section through a joint profile device according to the invention,

Fig. 2: A detail of the joint profile device according to Figure 1, and

Fig. 3 to 6: Individual steps of a method according to the invention for mounting the joint profile device according to the invention.

[26] The exemplary embodiment which in FIGS. 1 and 2 is a joint profile device 1 according to the invention and in FIGS. 3 to 6 an assembly of these

Joint profile device 1 describes comprises two structural parts 3, which are decoupled from each other by means of a joint 2. This gap 2 is by means of the invention

Jumper bridging device 1 bridged, wherein the building parts 3 are each connected to a side profile 4 in force transmitting manner. The side profiles 4 are each formed here by extruded aluminum profiles, which by means of bolt-shaped

Connecting means 25 are bolted to the building parts 3, respectively. Furthermore, the joint bridging device 1 has a covering device 5, which is formed here by a total of three sub-elements. These are initially edge profiles 18, which produce a direct contact of the cover 5 with the side profiles 4. Furthermore, the cover 5 includes a plurality of rungs 12 and a

Cover plate 13. Both the rungs 12 and the cover plate 13 extend from one side of the joint 2 to the other side, wherein respective lateral edges of the rungs 12 and the cover plate 13 each cooperate with one of the edge profiles 18. By means of the edge profiles 18, both the rungs and the cover plate 13 are indirectly connected to the side profiles 4 and lie on these. In a joint space of the joint 2 extends between the side profiles 4, a plurality of anchoring profiles 6. These each have a longitudinal axis 9, which are rotated relative to the longitudinal axes 10 of the side profiles 4. This is necessary because a length 7 of the anchoring profiles 6 exceeds a width 8 of the joint 2. This has the effect that the anchoring profiles 6 in the case of removal of the building parts 3 from each other - for example, as a result of earthquake - to a certain extent have a reserve of length to continue to be connected to both side profiles 4. It is understood that in the course of a widening of the gap 2, the obliquely oriented anchoring profiles 6 would "draw straight" at least to some extent.In order to be able to carry out such a movement, the anchoring profiles 6 each act with two joint devices 11

together, which allow a rotatability of the anchoring profiles 6 relative to the side profiles 4.

[28] In the example shown, the hinge devices 11 are each on

Coupling elements 19 are formed, by means of which the anchoring profiles 6 to the

Side profiles 4 are connected. For connection to the side profiles 4, the coupling elements 19 each have an engagement portion 29 which portion with a complementary engagement portion 30 of a respective side profile 4 can cooperate. In this way, the coupling elements form a positive engagement together with the side profiles. As is apparent from the figures, the engaging portion 29 of the

Coupling elements C-shaped. This applies analogously to the complementary groove of the engaging portion 30 of the respective associated side profile 4. The groove on the side profile 4 is compared to the corresponding springs of the coupling elements 19 carried out enlarged such that a rotation of the coupling elements 19 parallel to the longitudinal axis 10 of the side profiles 4 Axis is possible at least within a certain margin. In this way, the possibility is created that the coupling elements 19 can accommodate a certain relative movement of the two structural parts 3 to each other in a direction perpendicular to the joint.

[29] The hinge devices 11 are formed on the coupling elements 19 by means of a pin-shaped connecting means 22. For this purpose, a respective

Coupling element 19 opposing flanges 20, between which there is a free space. In this space is a corresponding end portion of a Middle element 21 of the anchoring profile 6 introduced, wherein both the flanges 20 and the central element 21 have corresponding openings. The

Connecting means 22 is guided through these openings, so that it is the respective

Coupling element 19 and the respective central part 21 positively connects with each other. The connecting means 22 is designed rotationally symmetrical. This ensures that the middle part 21 of the anchoring profile 6 and the respectively associated

Coupling element 19 about an axis of rotation 23 of the connecting means 22 are rotatable relative to each other.

[30] At least a majority of the anchoring profiles 6, preferably all

Anchoring profiles 6, are connected to the cover 5 by means of a connecting means 14. This connecting means 14 in the example shown by a

Threaded bolt formed. A respective connecting means 14, which connects an anchoring profile 6 with the covering device 5, interacts exclusively with a respectively associated rung 12 of the covering device 5. Typically, that can

Connecting means 14 are guided from an upper side of the respective rung 12 through an associated opening 31 of the rung. In the example shown, the force-transmitting connection between the rung 12 and the anchoring profile 6 takes place by means of a "flexible fixation." This is produced by means of a spring 17. For this purpose, the connection means 14 cooperates with a nut 32, which forms an abutment for the spring 17 At the opposite end, the spring 17 bears against an underside of the anchoring profile 6. An adjustment of the nut 32 makes it possible to adjust a spring force which is to be held in the spring unit 17. It is understood that the rung 12 and the anchoring profile 6 are connected to each other "stiffer", the stronger the spring 17 is biased. The spring 17 allows a movement of the cover 5 relative to the anchoring profile 6 in a direction parallel to a longitudinal axis 16 of the

Lanyard 14 is possible. Especially in the case of a force,

For example, as a result of an earthquake, this gives the possibility that the cover 5 can to a certain extent "lift off" the remaining joint bridging means 1. In this way it is ensured on the one hand that the covering device 5 does not drop uncontrollably from the joint bridging means 1 even in the event of an earthquake On the other hand, due to the mobility, the covering device 5 can considerably burden the joint bridging means 1 by external forces

survive unscathed. In the present embodiment, therefore, there is a vertically aligned restoring force, which causes a hold down of the cover. There this restoring force acts resilient, there is the advantage over a rigid connection that the risk of breakage of components is minimized.

Incidentally, the covering device 5 is centered overall by means of the connecting means 14 on the joint 2, so that the covering device 5 is always arranged centrally relative to the joint 2. It is also important that the connecting means 14 penetrates the respective associated anchoring profile 6 in the center, since in this way a rotation of the anchoring profile 6 relative to the building parts 3 has no influence on a movement of the connecting means 14 and consequently the cover 5. In other words, the connecting means 14 is arranged such that an axis of rotation 15 of the

Anchoring profile with the longitudinal axis 16 of the connecting means 14 coincides.

The rungs 12 of the cover 5 are connected at their two ends in each case by means of connecting means 27 with the respectively associated edge profiles 18. The connecting means 27 are designed in the example shown in the form of screws. The cover plate 13 is in turn connected by means of an adhesive layer 28 with the rungs 12. Overall, therefore, the edge strips 18, the rungs 12 and the cover 13, the cover 5. The edge strips 18 advantageously have a matched to the side profiles 4 geometry so that the most flush possible transition from an adjacent surface 33 is given to the joint bridging device 1. At a contact surface, which forms a respective edge profile 18 with the associated side profile 4, a sealing element 26 is arranged in the example shown, by means of which the edge profile 18 and the side profile 4 are sealed against each other.

The multi-part design of the covering device 5 according to the invention allows a particularly easy assembly of the joint bridging device 1 according to the invention. This results particularly well with reference to the individually shown in Figures 3 to 6

Assembly steps.

[35] In a first assembly step, the result of which is shown in FIG. 3, the side profiles 4 are each connected to the associated building parts 3. Then, in the example shown, a plurality of anchoring profiles 6 are arranged on the side profiles 4. For this purpose, the anchoring profiles 6 by means of their coupling elements 19 in a direction parallel to the longitudinal axes 10 of the side profiles 4 on the respective

corresponding engagement portion 30 of the side profiles 4 pushed. As can be seen in particular from FIG. 4, the anchoring profiles 6 are then in a position rotated with their longitudinal axis 9 relative to the longitudinal axis 10 of the side profiles 4. It is clearly visible that the length 7 of the anchoring profiles 6 exceeds the width 8 of the gap 2 to be bridged.

Even before the assembly of the joint bridging device 1 at the respective joint 2 were edge profiles 18 and a plurality of rungs 12 of

Covering device 5 connected together. A resulting ladder-shaped skeleton is particularly clearly visible in FIG. Likewise, connecting means 14 are already shown there by way of example, which can each be guided through a central opening 31 of the respectively associated rung 12. The anchoring profiles 6 are in turn likewise provided with corresponding central openings 34. The hitherto still unfinished covering device 5 is then connected to the anchoring profiles 6 in the next step, the result of which results from FIG. For this purpose, each of the connecting means 14 is guided both by an associated opening 31 of the associated rung 12 and the associated opening 34 of the associated anchoring profile 6 and connected by means of a nut 32 and a spring 17 in force transmitting manner with the respective anchoring profile 6. FIG. 5 shows particularly well that a free space 24 remains between the rungs 12 in each case. It is this clearance 24 which makes possible the particularly easy assembly of the joint bridging device as a whole - and in particular the covering device 5. Thus, it is readily possible, the

Connecting means 14 to connect from an upper side of the joint bridging means 1 with the anchoring profiles 6 by a sense can be gripped through the spaces 24 therethrough. This is just not possible with covering devices according to the prior art, since there the respective associated joint is completely covered by means of the covering device. Therefore, in the prior art in any case, the joint must be made accessible from a lateral edge, in which the respective

Cover is raised sideways. It is understood that this previous

Procedure is extremely cumbersome.

[37] In a final process step, at the end of which finally finished

Fugenüberbrückungseinrichtung arises, the cover plate 13 with the rest

Covering device 5 connected. In the example shown, it is glued to the sprouts 12 for this purpose. As a result, the joint 2 is now completely by means of

Jumper bridging device 1 bridged and in particular by means of

Covering device 5 completely covered.

It is understood that the individual features disclosed herein in connection with the joint bridging device 1 shown by way of example can also act independently of one another and consequently also independently of one another Joint bridging device can be realized. In other words, the individual features of the joint bridging device 1 shown by way of example are not necessarily dependent on each other.
