Description
TITLE: CONNECTION ELEMENT FOR FLOOR ELEMENTS OF VEHICLES </
The present invention relates to a connection element for connecting floor elements of a vehicle, an assembly of a first floor element, a second floor element and a connection element, as well as a rail vehicle having such a connection element or such an assembly.
Local and long-distance public transport vehicles, more specifically busses and rail vehicles, have floors made of several floor elements connected to each other.
Several floor elements are required due to the length inherent to the design of such vehicles.
In the area of the articulation of articulated buses and in the area of the articulation between different coaches of a rail vehicle, so-called pivot plates, which are guided as a particular floor element so as to rotate horizontally in the crossover area, are disposed on the floor.
The pivot plate serves as a walkway between two coaches of an articulated vehicle and must allow all the movements occurring between two coaches during travel, respectively absorb the load of passengers.
Articulated vehicles must be able to follow a large variety of movements during travel. Such a vehicle must more specifically allow for bending motions in the horizontal plane, which occur when such a vehicle drives around a curve.
Furthermore pitching motions (motions relative to vertical) which occur when such a vehicle drives over a crest or through a hollow must also be allowed. To a certain extent, rolling motions (torsion relative to the longitudinal axis) which occur for instance when the vehicles are being twisted relative to each other, must also be absorbed. It must furthermore be born in mind that the described motions can also occur simultaneously. More specifically in the area of a pivot plate, cornering and thus bending and possibly superimposed rolling and pitching motions, can result in extremely complex motion sequences in the area of the pivot plate.
In order to absorb such movements it is necessary to manufacture a flexible connection between floor elements, more specifically between the not rotatably mounted edge of a pivot plate and an adjacent floor element, which is not twistable relative to the pivot plate.
So far, a known solution has been a rubber profile which is fitted onto adjacent 1.0 edges of floor elements and thus connects two floor elements or one floor element with a pivot plate. Such a profile connection, which is used for instance in the tramway "Cobra" made by the company Bombardier, is however only adapted for a pivot plate with minor pitch and rolling mobility.
The document EP 1854691 A proposes a bridge with a pivot plate of a walkway between two vehicles connected to each other via an articulation, in which the pivot plate is connected with one of its ends to a so-called coupling plate of one of the vehicles via an elastic link. The elastic link, which is made of an elastomer or an elastic material, is screwed respectively with the coupling plate and the pivot plate via connecting bands. However, such a screw connection has disadvantages during assembly and maintenance.
An object of the invention was to solve the problems of the prior art described above. It was more specifically necessary to provide a connection element having a high mechanical stability during major pitch and rolling motions.

, The invention relates to a connection element for connecting floor elements of a vehicle, more specifically a rail vehicle, in the form of a profile with elastic properties, having - a base, which can be inserted into a groove of a first floor element, - a groove-shaped recess for receiving a bracket of a second floor element pointing downward, - a first lip for covering the top of an edge area of the first floor element, - a second lip for covering the top of an edge area of the second floor element, 1.0 the connection element having a first material which is an elastic material and a second material, the second material having a higher rigidity than the first material, and the connection element having the second material in the area of the groove-shaped recess and the first material in other areas.
The connection element allows a push-pull connection between adjacent floor elements, more specifically between a pivot plate and another floor element.
As opposed to solutions from the prior art, in which pivot plates are screwed with adjacent floor elements or with an elastic link, the solution according to the invention allows for a particularly simple maintenance and assembly/disassembly.
At the same time, the connection element according to the invention allows relatively ample angular movements of the elements relative to each other, more specifically relative to the vertical when a vehicle travels over crests or through hollows, and ample rolling motions (torsion relative to the longitudinal axis of the vehicle), with a simultaneously high stability of the connection element and reduced wear. The connection element combines elasticity and rigidity properties in order to achieve the afore-mentioned purposes.
In this description, the term "floor element" includes pivot plates and all current floor plates. So-called bridge plates or links which are disposed between a pivot plate and a firmly installed floor plate in the area of the articulation of articulated buses or rail vehicles are also included in this term. The connection element according to the invention can be used for connecting all kinds of combinations of floor elements. It can more specifically be used for connecting a pivot plate with another floor element.
In reference to the first lip and the first floor element, the term "covering an edge area" does not necessarily mean that the groove of the first floor element located in the edge area of the first floor element is also covered. The groove receives the base of the connection element and is not necessarily covered by the first lip.
The terms "first material" and "second material" can also be referred to as "part made of a first material" and "part made of a second material".
According to an fundamental idea, the connection element is manufactured from at least two different materials, in other words from two parts made of different materials, the first material providing the elastic properties which are required for the necessary angular movements, and the second material providing the necessary rigidity for achieving stability and reduced wear. Rigidity refers to the resistance of a body against deformation by a force or torque. Provided the rigidity is geometry-dependent, the term "higher rigidity" means a higher rigidity of the second material relative to the first material with the same geometry.
The second material preferably also has a higher solidity than the first material.
The solidity is a property of the material and describes the mechanical resistance which a material opposes to plastic deformation or separation.
The statement that the first material is an elastic material, does not mean that the second material does not have any elastic properties at all, but that the first material is more elastic than the second material and the elastic properties of the connection element are substantially conditioned by the first material.
In the area of the groove-shaped recess which receives a bracket of a floor element pointing downward, the connection element comprises the second material with a comparatively higher rigidity. In other words, the connection element is mechanically reinforced in the area of the groove-shaped recess by the second material. The groove-shaped recess is located in the second material, in other words, the walls of the groove-shaped recess are made of the second material.
Other areas of the connection element, such as for instance the first and second lip and areas of the base, are made of the first material with elastic properties.
The groove of the first floor element, in which the base of the connection element can be inserted and the bracket of the second floor element pointing downward run substantially parallel in the longitudinal direction. Thus, the groove-shaped recess in the connection element and the base of the connection element also run substantially parallel in the longitudinal direction.
In principle, the groove of the first floor element can be attached to or embedded in the floor element in any conceivable manner. In a particular embodiment, the groove of the first element is formed by three brackets, wherein one of the brackets can be connected to another part of the floor element, such as a floor plate for instance. The brackets can be substantially perpendicular to each other. In a particular embodiment, the bottom of the groove of the first floor element is wider than the groove aperture. This is achieved by the brackets being at an angle of less than 900 relative to each other.

It can more specifically be used for connecting a pivot plate with another floor element.
In reference to the first lip and the first floor element, the term "covering an edge area" does not necessarily mean that the groove of the first floor element located in the edge area of the first floor element is also covered. The groove receives the base of the connection element and is not necessarily covered by the first lip.
The terms "first material" and "second material" can also be referred to as "part made of a first material" and "part made of a second material".

In the area of the groove-shaped recess which receives a bracket of a floor element pointing downward, the connection element comprises the second material with a comparatively higher rigidity. In other words, the connection element is mechanically reinforced in the area of the groove-shaped recess by the second material. The groove-shaped recess is located in the second material, in other words, the walls of the groove-shaped recess are made of the second material.
Other areas of the connection element, such as for instance the first and second lip and areas of the base, are made of the first material with elastic properties.
The groove of the first floor element, in which the base of the connection element can be inserted and the bracket of the second floor element pointing downward run substantially parallel in the longitudinal direction. Thus, the groove-shaped recess in the connection element and the base of the connection element also run substantially parallel in the longitudinal direction.
In principle, the groove of the first floor element can be attached to or embedded in the floor element in any conceivable manner. In a particular embodiment, the groove of the first element is formed by three brackets, wherein one of the brackets can be connected to another part of the floor element, such as a floor plate for instance. The brackets can be substantially perpendicular to each other. In a particular embodiment, the bottom of the groove of the first floor element is wider than the groove aperture. This is achieved by the brackets being at an angle of less than 900 relative to each other.
The groove-shaped recess of the connection element is preferably disposed in the area of the base of the connection element and accessible from above.
In an embodiment of the invention, the bracket of the second floor element pointing downward rests on the walls of the groove-shaped recess of the connection elements or at least substantially with a minimal clearance. In other words, the bracket at least substantially fills the groove-shaped recess. In an advantageous variant of this embodiment, the aperture of the groove-shaped recess is wider than the slit width of the subjacent groove-shaped recess. A conical widening of the aperture can for instance be provided. The bracket pointing downward can thereby be more easily inserted and a bent area of the bracket can be received more easily.
In another embodiment, the groove-shaped recess is widened downward. This means, that the width of the groove-shaped recess increases from the slit-shaped aperture of the groove-shaped recess downward, i.e. in the direction of the bogie.
It is thereby achieved that the bracket of the second floor element inserted into the groove-shaped recess does not come to rest entirely on the wall of the groove-shaped recess and is movably mounted with some clearance. Major angular movements of the second floor element relative to the vertical are thereby facilitated. In this embodiment, the end of the bracket of the second floor element preferably doesn't rest against the bottom of the groove-shaped recess.
In a particular embodiment, the first material surrounds the second material, an access to the groove-shaped recess being left open. In a very particular embodiment, the cross-section of the second material is shaped like a circular arc, respectively has an arc-shaped contour with a section for the aperture of the groove-shaped recess. If the second material is shaped like an arc, the first material has a corresponding recess shaped like an arc, respectively a recess with an arc-shaped contour, in which the second material is inserted with positive locking.
The second material can be rotatably mounted in the first material. A gliding material, for instance a gliding layer, can be disposed between the two materials.
Due to the rotatable mounting, which allows a movement of the second material relative to the first material, floor plates can very easily perform vertical angular movements relative to each other. This embodiment can be advantageously combined with the embodiment described above in which the bracket of the lo second floor element rests on the walls of the groove-shaped recess of the connection element. The second material can have an arc-shaped cross-section as explained above, and be rotatably mounted in the first material.
The connection element can be configured in such a manner that a bracket of a second floor element can be fastened in the groove-shaped recess located in the second material, for instance by using a glue.
In a preferred embodiment of the connection element, the first material is an elastomer, for instance a (synthetic) caoutchouc or rubber, and the second material is a thermoplastic, preferably a polyamide.
As mentioned above, the connection element has a profile shape. The first and second material can be coextruded to form the profile. It is however also possible to extrude both materials separately and to join them to create the definitive profile, for instance by pressing, the second material being preferably pressed into the first material, or by gluing.
In a particular embodiment, the first material surrounds the second material and the second material is located in the area of the base of the connection element which can be inserted into the groove of a first floor element. When assembling the connection element with the floor plates, the first material, i.e. the part of the connection element made of the first material, can first of all be inserted into the groove of the first floor element. The part of the connection element made of the first material comprises the first and the second lip and the base, the outer sides of the base of the connection element, which rest on the walls of the groove of the first floor element, being made of the first material. The second material, i.e. the part of the connection element made of the second material, can then be inserted for example pressed, or pushed into the first material. As described above, the second material can have a cross-section shaped as a circular arc. In this embodiment, the first material correspondingly has a preferably complementarily arc-shaped recess, into which the second material, for instance a strand made of the second material, is inserted. The second material is more specifically rotatably mounted in the first material.
A method for assembling an assembly comprising a first floor element, a second floor element and a connection element as described above is specified, including the steps of:
- inserting the part made of the first material comprising the first lip, the second lip and the base into the groove of the first floor element;
- inserting a bracket of the second floor element pointing downward into the groove shaped recess formed in the part of the connection element comprising the second material;
- - inserting into the part made of the first material the part comprising the second material with the bracket of the second floor element inserted therein.
When possible and expedient, the method steps described above can occur in a different chronological order.
In an embodiment of the invention, the bracket of the second floor element pointing downward rests on the walls of the groove-shaped recess of the connection elements or at least substantially with a minimal clearance. In other words, the bracket at least substantially fills the groove-shaped recess. In an advantageous variant of this embodiment, the aperture of the groove-shaped recess is wider than the slit width of the subjacent groove-shaped recess. A conical widening of the aperture can for instance be provided. The bracket pointing downward can thereby be more easily inserted and a bent area of the bracket can be received more easily.
In another embodiment, the groove-shaped recess is widened downward. This means, that the width of the groove-shaped recess increases from the slit-shaped aperture of the groove-shaped recess downward, i.e. in the direction of the bogie.
It is thereby achieved that the bracket of the second floor element inserted into the groove-shaped recess does not come to rest entirely on the wall of the groove-shaped recess and is movably mounted with some clearance. Major angular movements of the second floor element relative to the vertical are thereby facilitated. In this embodiment, the end of the bracket of the second floor element preferably doesn't rest against the bottom of the groove-shaped recess.
In a particular embodiment, the first material surrounds the second material, an access to the groove-shaped recess being left open. In a very particular embodiment, the cross-section of the second material is shaped like a circular arc, respectively has an arc-shaped contour with a section for the aperture of the groove-shaped recess. If the second material is shaped like an arc, the first material has a corresponding recess shaped like an arc, respectively a recess with an arc-shaped contour, in which the second material is inserted with positive locking.
The second material can be rotatably mounted in the first material. A gliding material, for instance a gliding layer, can be disposed between the two materials.
Due to the rotatable mounting, which allows a movement of the second material relative to the first material, floor plates can very easily perform vertical angular movements relative to each other. This embodiment can be advantageously combined with the embodiment described above in which the bracket of the lo second floor element rests on the walls of the groove-shaped recess of the connection element. The second material can have an arc-shaped cross-section as explained above, and be rotatably mounted in the first material.
The connection element can be configured in such a manner that a bracket of a second floor element can be fastened in the groove-shaped recess located in the second material, for instance by using a glue.
In a preferred embodiment of the connection element, the first material is an elastomer, for instance a (synthetic) caoutchouc or rubber, and the second material is a thermoplastic, preferably a polyamide.
As mentioned above, the connection element has a profile shape. The first and second material can be coextruded to form the profile. It is however also possible to extrude both materials separately and to join them to create the definitive profile, for instance by pressing, the second material being preferably pressed into the first material, or by gluing.
In a particular embodiment, the first material surrounds the second material and the second material is located in the area of the base of the connection element which can be inserted into the groove of a first floor element. When assembling the connection element with the floor plates, the first material, i.e. the part of the connection element made of the first material, can first of all be inserted into the groove of the first floor element. The part of the connection element made of the first material comprises the first and the second lip and the base, the outer sides of the base of the connection element, which rest on the walls of the groove of the first floor element, being made of the first material. The second material, i.e. the part of the connection element made of the second material, can then be inserted for example pressed, or pushed into the first material. As described above, the second material can have a cross-section shaped as a circular arc. In this embodiment, the first material correspondingly has a preferably complementarily arc-shaped recess, into which the second material, for instance a strand made of the second material, is inserted. The second material is more specifically rotatably mounted in the first material.
A method for assembling an assembly comprising a first floor element, a second floor element and a connection element as described above is specified, including the steps of:
- inserting the part made of the first material comprising the first lip, the second lip and the base into the groove of the first floor element;
- inserting a bracket of the second floor element pointing downward into the groove shaped recess formed in the part of the connection element comprising the second material;
- - inserting into the part made of the first material the part comprising the second material with the bracket of the second floor element inserted therein.
When possible and expedient, the method steps described above can occur in a different chronological order.
The connection element can be configured in such a manner that the second material widens the first material in the area of the base of the connection element.
The widening can be achieved by a recess in the first material in which the second material is inserted, having a smaller cross-section than the cross-section of the second material, so that the first material widens when inserting the second material. The base of the connection element is thereby widened and a particularly tight fit in the groove of the first floor element is achieved. When inserting the second material into the first material, the profile of the connection element is widened in the area of the basis and a tight fit of the base in the groove of the first floor element is achieved.
In another variant, the base of the connection element is formed by the first as well as the second material in such a manner, that the outer sides of the base of the connection element which rest on the walls of the groove of the first floor element, are formed by the first and the second material. In this case, the first and the second material are connected to each other for instance at a common edge without the first material surrounding the second material.
In a variant, the connection element has a third material, which has a higher rigidity than the first material and is disposed between the first lip and the second lip, the lips being made of the first material. The third material serves to increase the stability of the elastic profiie between the first and the second lip.
The third material can be extruded with the other materials into a profile.
The profile of the connection element can altematively have a recess between the first and the second lip, in which the third material is inserted, for instance by gluing, pressing or clamping. In a preferred variant, the cross-section of the third material has a wedge-shaped profile.
The widening can be achieved by a recess in the first material in which the second material is inserted, having a smaller cross-section than the cross-section of the second material, so that the first material widens when inserting the second material. The base of the connection element is thereby widened and a particularly tight fit in the groove of the first floor element is achieved. When inserting the second material into the first material, the profile of the connection element is widened in the area of the basis and a tight fit of the base in the groove of the first floor element is achieved.
In another variant, the base of the connection element is formed by the first as well as the second material in such a manner, that the outer sides of the base of the connection element which rest on the walls of the groove of the first floor element, are formed by the first and the second material. In this case, the first and the second material are connected to each other for instance at a common edge without the first material surrounding the second material.
In a variant, the connection element has a third material, which has a higher rigidity than the first material and is disposed between the first lip and the second lip, the lips being made of the first material. The third material serves to increase the stability of the elastic profiie between the first and the second lip.
The third material can be extruded with the other materials into a profile.
The profile of the connection element can altematively have a recess between the first and the second lip, in which the third material is inserted, for instance by gluing, pressing or clamping. In a preferred variant, the cross-section of the third material has a wedge-shaped profile.
As mentioned above, the first material is made of an elastic material. The third material can be a thermoplastic, preferably a polyamide. With regard to its chemical composition, the third material can be the same material as the second material.
The invention also relates to an assembly of a first floor element, a second floor element and a connection element as described above, the connection element connecting the first floor element to the second element. One of the floor elements is preferably a pivot plate. The assembly can be assembled in different ways.
To begin with, the base of the connection element can for instance be inserted into the groove of the first floor element. The bracket of the second floor element pointing downward is then inserted into the groove-shaped recess of the connection element. To this end, the second lip is lifted as much as is necessary. The assembly can however also be carried out in reverse order. Other particular ways of assembly have been described above. The bracket of the second floor element pointing downward can be fixed in the groove-shaped recess of the connection element, for instance by use of a glue.
In addition, the invention relates to a rail vehicle, having a connection element as described above or an assembly as described above.
Other possible combinations of the embodiments and aspects described above are explicitly encouraged.
The invention is described in the following based on particular embodiments.
In the drawings:
Fig. 1 shows an assembly consisting of a pivot plate, bridge elements and a floor plate, each connected to connection elements according to the invention, =
.' Fig. 2 shows a sectional view of a bridge element, a first embodiment of a connection element and a floor plate along the line I-1 shown in Fig. 1, Fig. 3 shows a sectional view of a bridge element, a second embodiment of a connection element and a floor plate, along the line I-1 shown in Fig. 1.
s The assembly in fig. 1 is installed in the area of the crossover between two coaches of a rail vehicle. It consists of a pivot plate 10, bridge plates 11, 12, 13 and floor plates 14, 20. The pivot plate 10, the bridge plate 11, 12, 13 and the floor plate 14 are connected to each other via connection elements 15, 16, 17, 18.
The 1.0 floor plate 14 is connected to a first coach body and the floor plate 20 is connected to a second coach body. The pivot plate is rotatably mounted with its arc-shaped edge 19 on the floor plate 20. A tension bar 21, which covers the transition between the pivot plate 10 and the floor plate 20 and is fixed to the floor plate 20 by screws 42, is provided in the area of the transition between the pivot plate 10 15 and the floor plate 20.
Fig. 2 is a sectional view along the line I-1 in Fig. 1 showing the floor plate 12, a connection element 18 according to the invention and the floor plate 14. The connection element 18 has a profile shape with a base 22, a first lip 23, a second 20 lip 24, and a groove-shaped recess 25 in the area of the base 22 of the profile. A
bracket 26 of the bridge plate 12 pointing downward is inserted into the groove-shaped recess and glued therein. There is a little clearance between the bracket 26 and the walls of the groove-shaped recess 25 for receiving glue. The lip 24 covers the edge area of the bridge plate 12 which is substantially formed by the 25 bracket 26 bent downward. The gaps between the lip 23 and the floor plate 14, respectively between the lip 23 and the bridge plate 12 shown in the figure are not mandatory. The lips can also rest directly on the plates. The same applies to figure 3.
The base 22 of the connection element 18 is inserted into a groove of the floor plate 14. The groove of the floor plate 14 is formed by the brackets 27, 28, which surround the base 22 of the profile. In the shown embodiment, the bottom of the groove of the first floor element is wider than the aperture of the groove, since the brackets 27, 28, 29 are at an angle of less than 900 relative to each other. The basis 22 is thus tightly held in the groove. The bracket 29 is connected to the supporting element 30 of the floor plate 14. The lip 23 covers an edge area of the floor plate 14, in this case of the supporting element 30.
1.0 The connection element consists of a first elastic material 31 (respectively a part made of a first elastic material 31) and a second material 32 (respectively a part made of a second material 32) with a higher rigidity. The part made of the second material 32 is a strand with an arc-shaped cross-section, in which the groove-shaped recess 25 is embedded from above. In the embodiment shown here, the first material 21 encompasses the second material 32, the aperture 40 of the groove-shaped recess 25 being left open for receiving the bracket 26. Due to a conical widening, the aperture 40 is wider than the width of the slit of the subjacent groove-shaped recess 25. The second material is located in an arc-shaped recess 37 in the first material. In this embodiment, the part made of the second material 32 is rotatably disposed in the part made of the first material 31. Due to their rotatability, the bridge plate 12 and the floor plate 14 which are connected to each other by the connection element 18 can easily move relative to each other in a pitching motion. Alternately, the second material can also be fixedly attached in the first material.
The outer sides of the profile base 22, i.e. the sides which are encompassed in the brackets 27, 28, 29, are formed by the first material.
A strand of a third material 34, having a wedge-shaped cross-section is pressed into a recess 33 between the first lip 23 and the second lip 24. The third material has a higher rigidity than the first material 31.
In order to undo the push-pull connection, the wedge-shaped strand made of the third material 34 is first pulled out of the recess 33. The lip 24 is then folded upward which can be easily done via the recess 33. The bridge plate 12, respectively its brackets are then pulled out of the connection element.
If the bracket 26 is glued to the part made of the second material 32, and the part 32 is rotatably disposed in the part made of the first material 31 ¨ 31 and 32 thus being not fixedly connected, the part 32 is pulled out of the connection element 18 together with the bracket 26. The plates 12 and 14 are subsequently separated and the plate 12 can be lifted upward.
If desired, the base 22 of the connection part 10 can be pulled out of the groove formed by the brackets 27, 28, 29, for instance by holding on to the lips 23, 24 and pulling upward. This is however not necessary for disconnecting the connection between the plates 12 and 14.
The assembly of the push and pull connection can occur in reverse order as described above.
The part of the connection element 18 consisting of the first material 31 can be inserted into the groove of the first floor element 14, this part made of the first material 31 having the first lip 23, the second lip 24 and the base 22, the base 22 being inserted into the groove of the first floor element 14. The bracket 26 of the second floor element 12 pointing downward can then be inserted into the groove-shaped recess 25 which is formed in the part of the connection element 18 consisting of the second material 32. The bracket is more specifically glued into the groove-shaped recess 25. The part made of the second material 32 with the bracket 26 of the second floor element 12 inserted therein, can finally be inserted into the part made of the first material 31, the first material 31 encompassing the second material 32. The second material 32 preferably remains rotatable in the first material 31. If possible and expedient, the afore-mentioned method steps can occur in different chronological orders. The result is the assembly shown in fig. 2 Alternately, assembling the connection element 18 with the bridge plate 12 and the floor plate 14 can also occur in such a manner that the part consisting of the first lo material 31 is first inserted into the groove formed by the brackets 27, 28, 29 and that the part consisting of the second material 32 is subsequently pressed into the first material, i.e. into the arc-shaped recess 37, to which end the lip 24 is lifted as much as required. The base 22 can thereby be widened depending on the dimension of the recess, and fits tightly in the groove. The bracket 26 can then be inserted into the groove-shaped recess, to which end the lip 24 is lifted as much as required.
Another embodiment of a connection element is shown in fig. 3. Parts which are the same in the first embodiment according to fig. 2 are labeled with the same reference numbers. Unlike the embodiment according to fig. 2, the second material 32 is not surrounded by the first material 31. The outer sides of the profile base, i.e. the sides which are encompassed in the brackets 27, 28, 29, are made of the first material 31 as well as the second material 32, which are connected to each other at a common edge 35 and together form the profile base 22. In this embodiment both materials 31, 32 can for instance be co-extruded and the profile base is subsequently pressed into the groove formed by the brackets 27, 28, 29.
Another difference with respect to the embodiment according to Fig. 2, is that the groove-shaped recess 25 in the connection element 18 is widened downward in direction of the end 36 of the bracket 26 and that the bracket 26 inserted into the groove-shaped recess from above does not completely rest against the walls of the groove-shaped recess. The end 36 of the bracket 26 furthermore does not rest on the bottom of the groove. The bracket 26 and the bridge plate 12 connected to it can thus perform major pitching motions (angular motions relative to the vertical) relative to the floor plate 14. In this embodiment, the bracket 26 is not fixed, more specifically not glued in the groove-shaped recess. The angular motions of the bridge plate 12 relative to the floor plate 14 are indicated by the arrows N.
The embodiments of a connection element shown are not limited to the connection element 18 shown in Fig. 1. The connection elements 15, 16 and 17 can also be configured in this manner.
The invention also relates to an assembly of a first floor element, a second floor element and a connection element as described above, the connection element connecting the first floor element to the second element. One of the floor elements is preferably a pivot plate. The assembly can be assembled in different ways.
To begin with, the base of the connection element can for instance be inserted into the groove of the first floor element. The bracket of the second floor element pointing downward is then inserted into the groove-shaped recess of the connection element. To this end, the second lip is lifted as much as is necessary. The assembly can however also be carried out in reverse order. Other particular ways of assembly have been described above. The bracket of the second floor element pointing downward can be fixed in the groove-shaped recess of the connection element, for instance by use of a glue.

The second material is located in an arc-shaped recess 37 in the first material. In this embodiment, the part made of the second material 32 is rotatably disposed in the part made of the first material 31. Due to their rotatability, the bridge plate 12 and the floor plate 14 which are connected to each other by the connection element 18 can easily move relative to each other in a pitching motion. Alternately, the second material can also be fixedly attached in the first material.
The outer sides of the profile base 22, i.e. the sides which are encompassed in the brackets 27, 28, 29, are formed by the first material.
A strand of a third material 34, having a wedge-shaped cross-section is pressed into a recess 33 between the first lip 23 and the second lip 24. The third material has a higher rigidity than the first material 31.
