Description

[0001] CONNECTOR AND METHOD FOR CONNECTING A FIRST PLATE TO A SECOND PLATE

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to a connector for connecting a first plate to a second plate.

[0004] Furthermore, the present invention relates to a method for connecting a first plate to a second plate using a connector according to the invention.

[0005] STATE OF THE ART

[0006] For example, in order to safely and easily drive heavy equipment, such as trucks or excavators, over unpaved ground on a construction site, it is common practice to lay slabs that provide a sufficiently stable surface. Another application example is the creation of a stable floor at open-air events, such as the floor, particularly in the spectator area, at open-air concerts. The upper surface of the slabs can be suitably structured to achieve the desired adhesion properties. Such slabs are sometimes also referred to as floor protection mats.

[0007] In particular, panels made of

[0008] Plastic or a composite material made of plastic is used. Compared to metal panels, it has the advantage of being much lighter, which in turn increases transport options and makes handling during assembly much easier. The size of an individual panel is typically a few meters long, with rectangular panels being commonly used. For example, panels measuring 3 m long and 2 m wide are commercially available. Depending on the thickness, a panel made of plastic can therefore weigh several hundred kilograms.

[0009] For example, plastic panels with the dimensions mentioned above of 3 mx 2 m are known, which have a thickness of 47.5 mm and weigh 235 kg each.

[0010] To prevent the panels from shifting significantly, e.g. when driven over, which would mean that the desired stable surface would no longer be guaranteed, the panels must be connected to one another. Theoretically, when covering a narrow strip (for example to create a small path with a stable surface) it is sufficient to lay the panels linearly so that connections are only required in one direction and not across it. In most cases, however, large sections of ground have to be covered and the panels laid in two directions and connected to one another. For this purpose, the panels are usually screwed together using perforated metal sheets or perforated steel strips as connectors, whereby the panels can simply be laid next to one another. Accordingly, threads for the screws are cut into the panels, although the mechanical stability of these threads often leaves something to be desired.In addition, screwing is quite time-consuming, even when using cordless screwdrivers, since usually several screws have to be screwed in per connector. Furthermore, the perforated sheets, steel bands or screws used usually protrude somewhat from the surface of the panels or the screw heads at least protrude from the connectors. These protruding parts are at great risk if the panels are driven over by heavy machinery, particularly those with chain drives, i.e. there is then a risk that the connection will be separated. Finally, this solution is disadvantageous in that the connectors in particular expand and contract when exposed to strong temperature fluctuations, which can also lead to the destruction of the (screw) connection.

[0011] WO 2020 / 209805 A1 discloses a connector for panels that are to be laid in an overlapping manner, which can be integrated into the panels in the area intended for the overlap. This connector is therefore primarily suitable for sufficiently thick panels, which are typically 8 cm thick, which represents an additional – and therefore disadvantageous – limitation. In addition, laying overlapping panels is considerably more complex than simply laying non-overlapping panels next to one another, with the areas intended for the overlap usually having a different thickness than the rest of the panel. Furthermore, attention must be paid to the correct sequence of panel edges, which are to be arranged above or below the edges of adjacent panels. Overall, therefore, very precise laying is required, which entails a corresponding amount of effort.

[0012] OBJECT OF THE INVENTION

[0013] It is therefore an object of the present invention to provide a connector and a method for connecting a first panel to a second panel which avoid the disadvantages mentioned above. In particular, the connection should be quick and uncomplicated, even if the panels are laid flat and not just in one direction. Preferably, the connection should not be restricted to panels with a certain thickness. Preferably, the connection should not cause any protruding parts. In particular, the connection should be robust against temperature fluctuations. Preferably, the connection should not place high demands on the accuracy when laying the panels, in particular with regard to the exact spacing and / or the exact alignment of the panels to one another.

[0014] PRESENTATION OF THE INVENTION

[0015] To achieve the stated object, the invention provides a connector for connecting a first plate to a second plate, the connector comprising a first end section, a second end section and a central section arranged between the first end section and the second end section and connecting them, wherein the central section has an upper side and a lower side opposite the upper side and extends parallel to a first direction which is parallel to a longitudinal axis of the connector and points from the second end section to the first end section, wherein the first end section runs at least in sections with a directional component antiparallel to a second direction and / or with a directional component parallel to a third direction,in order to bring the connector into a closed position at least by pivoting the connector once about at least one pivot axis running parallel to the third direction and in doing so to be able to establish a positive connection of the first end section with a first receptacle of the first plate when the connector with the first end section is inserted at least partially into the first receptacle, wherein the second direction is normal to the first direction and points from the underside to the top of the central section and wherein the third direction is normal to the first direction and to the second direction, wherein the second end section has a movable locking mechanism in order to be able to establish a detachable connection with a second receptacle of the second plate when, in the closed position, the second end section is at least partially arranged in the second receptacle.

[0016] This means that the connector enables two adjacent panels to be connected extremely quickly - and can therefore also be referred to as a quick connector - because during the connection process, only the first end section creates a positive connection with the first receptacle of the first panel, and for fixing, it is sufficient to connect the second end section to the second receptacle of the second panel using the movable lock. Overlapping of the panels to be connected is not necessary, which is why the thickness or material strength of the panels does not have to be reduced for overlapping, and the risk of panel breakage is correspondingly greatly reduced.Due to the design of the connector, in particular of the first end section, the said positive connection is produced more or less automatically when the connector is brought into the corresponding closed position, wherein in this case a pivoting about the pivot axis lying parallel to the third direction takes place, which is expressed by the formulation "at least by pivoting the connector at least once about at least one pivot axis running parallel to the third direction". This means that it is possible that further movements of the connector, such as one or more translations and / or one or more further pivotings about the same or other pivot axes - before and / or after and / or simultaneously with the one-off pivoting about the pivot axis running parallel to the third direction for transferring the connector into the.

[0017] Closing position is possible or even necessary.

[0018] The arrangement of the pivot axis running parallel to the third direction is preferably understood as fixed relative to the connector. Otherwise, i.e., with a spatially fixed pivot axis, for example, in the case of a superimposed translation, mathematically speaking, an infinite number of pivot axes would be understood as "at least one pivot axis running parallel to the third direction."

[0019] The orientation of the third direction is—unlike the first and second directions—open. Accordingly, "parallel" in the context of the third direction should be understood to include antiparallel.

[0020] From the above, it follows that in the closed position, the connector is at least in engagement with the first plate, whereby a positive connection is established between the first end section and the first receptacle. Given the presence of the second plate—and its suitable arrangement relative to the first plate—the connector in the closed position can releasably connect the two plates to one another by means of the movable locking mechanism, if the second end section is then at least partially arranged in the second receptacle.

[0021] In the closed position, the underside of the central section faces at least the first plate or the upper side of the central section faces away from the first plate.

[0022] The central section can have a wide variety of shapes and, for example, be designed in a web-like manner, which represents a simple and cost-effective variant in terms of manufacturing technology, in which protruding parts of the central section are avoided and which ensures high mechanical stability, particularly with regard to tensile loads. It has been shown that such tensile loads occur particularly when the plates connected with the connector according to the invention are subjected to forces that threaten to shift the position of the plates relative to one another, e.g. due to heavy vehicles driving over them.

[0023] Preferably, the central section runs parallel to the first direction.

[0024] A wide variety of configurations are possible for the positive connection between the first end section and the first receptacle, with the first end section and the first receptacle being designed or coordinated with each other to enable said positive connection. In other words, the first receptacle is clearly designed to correspond to the first end section of the connector—one could also refer to it as a "corresponding first receptacle"—and vice versa.

[0025] The course of the first end section deviates at least in sections from the first direction. In the simplest case, the first end section is bar-shaped and runs slightly “downwards” or away from the top side of the middle section and thus with a direction component anti-parallel to the second direction. This means that the course of the first end section is curved or kinked away from the top side of the middle section and has a direction component parallel to the first direction and a direction component anti-parallel to the second direction. The first receptacle can be designed in the shape of a slot, into which slot the first end section can be inserted. In this case, it can be necessary to produce the positive connection orto transfer the connector into the closed position, it is sufficient if the first end section, which is at least partially inserted into the first receptacle, is pivoted about the pivot axis running parallel to the third direction.

[0026] However, a T-shaped first end section would also be conceivable, for example, wherein the "crossbar" of the T-shape runs parallel to the third direction and the first receptacle is designed to accommodate the crossbar, for example with two hook-shaped sections. In this case too, it is necessary to pivot the connector - at least a little, for example by a few degrees, such as less than 5 ° or less than 3 ° - about a pivot axis running parallel to the third direction in order to move the connector into the closed position. Typically, in this case, a translation of the connector inserted into the first receptacle is necessary before pivoting in order to produce the positive connection and bring the connector into the closed position.

[0027] In general, the first end section can have several sections - which can run differently - and can, for example, be fork-shaped, whereby it would be conceivable that the fork arms run differently.

[0028] Alternatively or additionally, it is of course also possible for the first end section to have a plurality of sections which adjoin one another, wherein the resulting course can lie in one or more planes. For example, the first end section can be bent downwards in a first section, i.e. with a directional component parallel to the first direction and a directional component antiparallel to the second direction, and can be bent to the side in a second section which adjoins it, viewed in the first direction, i.e. with a directional component parallel to the third direction. In this example, in which the course of the first end section (orof the first and second section of the first end section) lies in two planes overall, transferring the connector into the closed position typically requires at least one further pivoting, which is preferably to be carried out before the pivoting about the pivot axis running parallel to the third direction.

[0029] The movable locking mechanism can be actuated by movement. For this purpose, purely mechanical locks, such as those with a sliding, pivoting, or rotating latch, are suitable. However, it would also be conceivable, for example, for the movable locking mechanism to be designed in the style of a bayonet lock.

[0030] The second receptacle is clearly designed to correspond to the second end section - one could also speak of a "corresponding second receptacle" - and vice versa. Said design serves to enable the second end section to be arranged at least in sections in the second receptacle on the one hand and to enable detachable connection by means of the locking mechanism on the other. With regard to the at least partial arrangement of the second end section in the second receptacle, it should be noted that here too a certain form fit can of course be provided between the second end section and the second receptacle, if necessary taking into account any desired tolerances. In this sense, the second end section and the second receptacle are coordinated with one another.

[0031] Both the positive connection between the first end section and the first receptacle and the movable locking mechanism for the detachable connection between the second end section and the second receptacle can be used for panels of very different thicknesses, since with an appropriate design of the connector the design of the corresponding first and second receptacles can be very simple - and thus with sufficient mechanical stability even with a small thickness.

[0032] Analogous to the above, the invention provides a method for connecting a first plate to a second plate with a connector according to the invention, wherein the first plate has a first receptacle formed corresponding to the first end section and the second plate has a second receptacle formed corresponding to the second end section, the method comprising the following steps:

[0033] - Arranging the first plate and the second plate next to each other so that the first receptacle and the second receptacle are opposite each other;

[0034] - inserting at least part of the first end section into the first receptacle;

[0035] - Transferring the connector into the closed position, wherein the transfer comprises at least a single pivoting of the connector about at least one pivot axis running parallel to the third direction, wherein during the transfer into the closed position a positive connection, preferably with tolerance in the first and / or second and / or third direction, is produced between the first end section and the first receptacle and wherein during the transfer into the closed position the second end section is arranged at least in sections in the second receptacle;

[0036] - Producing a detachable connection between the second end portion and the second receptacle by actuating the movable locking mechanism of the second end portion.

[0037] Intermediate steps are also possible. In particular, as is clear from the above, one or more pivoting and / or translational movements are conceivable, which can take place before and / or after and / or simultaneously with the single pivoting about the pivot axis running parallel to the third direction. Of course, several connectors can also be provided, which then engage accordingly in several first receptacles of the first plate and in several second receptacles of the second plate.

[0038] As already mentioned, the first end section can comprise or, of course, consist of several adjoining sections. It would also be conceivable for each arm, with several arms, to have several adjoining sections with different profiles. In a preferred embodiment of the connector according to the invention, the profile of the first end section, at least in sections, has at least two kinks and / or bends, preferably essentially an S-shape.

[0039] As already described, the resulting course of the first end section does not have to lie in a plane, but can, for example, be a kink / bend downwards and the following kink / bend to the side.

[0040] In the S-shape mentioned, however, the two kinks / bends are in one plane. However, this does not preclude the possibility of a further adjoining section being provided, the course of which lies in a different plane, or of a further section being provided which is part of another arm of the first end section, so that in this case, too, the course of the first end section as a whole lies in several planes.

[0041] The S-shape of the first end section promotes a particularly secure form fit with the first receptacle in that a particularly simple geometric design - essentially in the form of a slot - is sufficient for this in the first receptacle. If the first end section only has the S-shape and no further sections, in particular no further sections which run in other planes, then when the first end section is inserted into the first receptacle, it is sufficient to pivot it once about the pivot axis running parallel to the third direction in order to move the connector into the closed position. This ensures that the user can handle the connector particularly quickly and easily and to connect the first plate to the second plate particularly securely. The plane in which the first end section lies is then parallel to the longitudinal axis of the connector or the longitudinal axis lies in this plane.

[0042] Accordingly, in a preferred embodiment of the connector according to the invention, the first end section extends in a plane that is preferably parallel to the longitudinal axis of the connector. This is advantageous in terms of manufacturing technology because it is simpler, and it simplifies handling for the user. As stated, the longitudinal axis can also lie in the plane in which the first end section extends.

[0043] In a preferred embodiment of the connector according to the invention, the first end section and the middle section are manufactured together from one piece, preferably from metal, particularly preferably from stainless steel or coated steel. The one-piece production is advantageous in terms of stability but also handling for the user. Furthermore, depending on the complexity of the first end section or its shape, simple production can be ensured, for example by performing only one or more bending processes to produce the first end section.

[0044] Using metal as a material ensures the highest standards of mechanical stability. In principle, even non-corrosive metals or...

[0045] Metal alloys are conceivable.

[0046] With regard to advantageous corrosion resistance or corrosion protection, stainless steel or coated steel is particularly suitable, whereby steel also includes stainless steel. The coating mentioned can be, for example, galvanization, a suitable paint, or a plastic layer.

[0047] In principle, however, other sufficiently mechanically stable materials are of course not excluded, such as correspondingly stable plastics or composite materials such as fiber-reinforced plastics.

[0048] In a preferred embodiment of the connector according to the invention, the second end section is made, at least in sections, from the same material as the first end section and / or the central section. This proves advantageous with regard to manufacturing and thus costs, and can also provide mechanical advantages.

[0049] In particular, the second end section can be made at least in sections from metal, preferably from stainless steel or coated steel.

[0050] As already mentioned, a wide variety of movable locking mechanisms can be provided for the second end section. For example, a screw lock or locking mechanism with a movable lock would be conceivable. In order to provide a locking mechanism that is particularly easy to handle and quick to operate for the user, a preferred embodiment of the connector according to the invention provides that the movable

[0051] The locking mechanism of the second end section is designed as a rotary latch with a locking element that can be rotated by means of an actuating element about a rotation axis that preferably runs parallel to the second direction. This design also allows for a particularly space-saving construction, while avoiding protruding components.

[0052] Accordingly, there is no damage to the connector or the locking mechanism when vehicles, in particular heavy vehicles such as trucks or tracked vehicles, drive over the plates connected by means of the connector according to the invention.

[0053] The second receptacle accordingly has at least one engagement section which is designed such that it is positively connected to the locking element when the locking element is arranged in a closed position. In an insertion position of the locking element, however, there is no positive connection and the second end section can therefore be easily inserted into the second receptacle or at least partially arranged therein. By rotation about the axis of rotation, the locking element can be moved from the insertion position into the closed position and vice versa.

[0054] In a particularly preferred embodiment of the connector according to the invention, it is provided that the locking element is movably mounted with the actuating element along the axis of rotation, wherein a spring element is provided to urge the locking element with the actuating element into a specific position. This mobility ensures a certain flexibility or tolerance parallel to the axis of rotation with regard to the precise arrangement of the connector, in particular of the locking element, relative to the second receptacle, in particular to its engagement section.

[0055] This is because the locking element can be moved along the axis of rotation against the spring force of the spring element, if necessary, in order to bring the locking element into the closed position and to establish a positive connection with the engagement section. This in turn makes application easier for the user. To ensure simple operation for the user, a particularly preferred embodiment of the connector according to the invention provides that the locking element can be rotated at least from an insertion position into a closed position and vice versa, with locking means preferably being provided in order to be able to hold the locking element in at least one of the two positions in such a way that a rotational movement is only made possible when a minimum torque is applied.The latter ensures, on the one hand, particularly clear operability for the user and, on the other hand, represents an increase in safety, as it reliably prevents the locking mechanism from being actuated unintentionally or the locking element with the actuating element from moving independently from the insertion position to the locking position and vice versa - for example in the event of vibrations.

[0056] For this purpose, a locking mechanism can be provided, for example, which comprises a knob and a corresponding recess in which the knob can be arranged. Because the knob and / or the recess are elastic, the elasticity can be used to adjust the minimum torque that must be applied to guide the knob out of the recess.

[0057] If the aforementioned spring element is provided to hold the locking element with the actuating element in position relative to the rotation axis or to urge it into a specific position, the spring element can form part of the locking means. In the described example of the knob and the corresponding recess, for example, one of these elements can be spring-loaded by the spring element, thereby generating the described elasticity.

[0058] Analogous to what has been said above, the invention provides a system with at least one connector according to the invention and a first plate with at least one first receptacle, wherein the respective connector is arranged in the closed position with its first end section in a form-fitting manner in the respective first receptacle, wherein preferably at least one recess is provided in the first plate, in which the central section of the respective connector is arranged at least in sections when the respective connector is in the closed position. The at least one recess ensures that the connector hardly protrudes, or not at all, above the walkable or driveable surface of the first plate when the connector is in the closed position. Accordingly, the connector cannot be damaged by vehicles driving over the first plate and a secure connection can be ensured.

[0059] An advantage of the positive connection of the first end section to the first receptacle that should not be overestimated is that tolerances in various directions are possible, although the connector allows for extremely rapid connection. Accordingly, in a preferred embodiment of the system according to the invention, the positive connection is provided with a tolerance in the first direction and / or with a tolerance in the second direction and / or with a tolerance in the third direction. Said tolerances are typically in the range of a few millimeters, preferably less than 10 mm, particularly preferably less than 5 mm.

[0060] These tolerances are advantageous in several ways. First, large temperature fluctuations are not a problem when the connector is in the closed position, as there is enough space to allow for temperature-induced expansion and / or contraction of the connector—and also of the (first and second) plates—without compromising the connection provided by the connector.

[0061] On the other hand, even with an imperfect arrangement of the first and second panels, particularly with regard to their alignment and / or spacing from one another, a reliable connection can be achieved by means of the connector, since the connector can be arranged, within the tolerances mentioned, both with the first end section in a form-fitting manner in the first receptacle and with the second end section in the second receptacle. This not only makes it easier for the user to connect the panels using the connector according to the invention, but also simplifies the installation of the panels, thus helping to save time and money because less precision is required.

[0062] The design of the first receptacle is generally possible by appropriate machining of the first plate, particularly when simple drilling or milling is sufficient to produce a shape corresponding to the first end section, which is suitable for establishing the positive connection in the closed position. Particularly with such simple geometries, the material of the plate itself typically provides sufficient mechanical stability, even if the respective first plate is not particularly thick.In a preferred embodiment of the system according to the invention, it is provided that the respective first receptacle comprises a first receptacle opening and a first receptacle element made of metal, preferably of stainless steel or coated steel, wherein the first receptacle element is fastened, preferably detachably, and is arranged at least in sections in the first receptacle opening, wherein the first receptacle element is shaped to correspond to the first end section of the respective connector and, in the closed position of the respective connector, there is a positive connection between its first end section and the first receptacle element. The said fastening of the first receptacle element is clearly to be understood as fastening to the remaining first plate or to a body of the first plate.

[0063] In this way, in particular tensile forces that are parallel and / or antiparallel to the first direction and / or that are parallel and / or antiparallel to the second direction can be transmitted between the respective connector in its closed position and the first plate. Of course, the transmission of forces parallel (or antiparallel) to the third direction is also conceivable. More precisely, the direction information means that the transmittable forces have such directional component(s) or act in the said direction(s), whereby an overall resulting tensile force can be a corresponding superposition of the individual forces.

[0064] The first receiving element can be secured, for example, using first fastening elements (e.g., screws or rivets) that can be arranged outside the first receiving openings, i.e., they do not need to be arranged in the first receiving opening. The fastening can, if necessary, be detachable.

[0065] However, variants are also conceivable in which the respective first receiving element is glued for fastening, for example.

[0066] The respective "corresponding" first receiving element is to be understood as being designed to correspond to the first end section with regard to the positive connection to be achieved with the first end section. This means that the geometry of the respective first receiving element can be optimally matched to the geometry of the first end section of the respective connector in order to ensure the positive connection, in particular with desired tolerances.

[0067] The first receiving element offers a number of advantages. Firstly, it offers a certain degree of independence from the respective plate thickness of the first plates. Due to the material used, the first receiving element has a high degree of mechanical stability and can be easily used even in thin plates. Only the first receiving openings need to be produced in the plates themselves – more complex geometries for establishing a positive connection with the first end section of the respective connector, however, no longer need to be manufactured from the plate material.

[0068] The geometry of the first receiving opening is typically limited to a hole with a substantially circular cross-section or a substantially rectangular cross-section (possibly with rounded corners). The more complex geometries mentioned above, however, are formed by the first receiving element – ​​with corresponding mechanical stability.

[0069] The geometry of each first receiving element can also be adapted to different requirements with relatively little effort, for example, if differently shaped end sections of the respective connector are desired. The geometry of each first receiving opening can always remain the same, i.e., nothing needs to be changed on the plate manufacturing side, thus keeping additional costs to a minimum.

[0070] With regard to the corrosion resistance or corrosion protection of the first receiving element through the choice of material, stainless steel or coated steel, what was said above in connection with the connector applies analogously. Analogous to what was said above, a preferred embodiment of the system according to the invention provides for a second plate with at least one second receptacle, wherein the respective connector, in the closed position, is arranged with its second end section at least partially in the respective second receptacle and can be detachably connected to the respective second receptacle by means of the movable locking mechanism, wherein preferably at least one recess is provided in the second plate, in which the central section of the respective connector is arranged at least partially when the respective connector is in the closed position.The at least one recess ensures that the connector protrudes little or not at all above the walkable or driveable surface of the second plate when the connector is in the closed position. Accordingly, the connector cannot be damaged by vehicles driving over the second plate, thus ensuring a secure connection.

[0071] The design of the second receptacle is generally possible by appropriate machining of the second plate, particularly when simple drilling or milling is sufficient to produce a simple geometry in order to create a shape corresponding to the second end section that is suitable for establishing the connection with the movable locking mechanism in the closed position. In particular with such simple geometries, the material of the plate itself typically provides sufficient mechanical stability, even if the respective second plate is not particularly thick. The second receptacle of the second plate can, however, also be designed analogously to the first receptacle with the first receptacle opening and the first receptacle element.Therefore, in a particularly preferred embodiment of the system according to the invention, it is provided that the respective second receptacle comprises a second receptacle opening and a second receptacle element made of metal, preferably of stainless steel or coated steel, wherein the second receptacle element is fastened, preferably detachably, and is arranged at least in sections in the second receptacle opening, wherein the second receptacle element is shaped to correspond to the second end section of the respective connector and, in the closed position of the respective connector, a detachable connection can be produced between the respective connector and the second receptacle element of the respective second receptacle by means of the locking mechanism of its second end section. The said fastening of the second receptacle element is clearly to be understood as fastening to the remaining second plate or to a body of the second plate.

[0072] In this way, not only tensile forces that are parallel and / or antiparallel to the first direction, but also tensile forces that are parallel and / or antiparallel to the second direction can be transmitted between the respective connector in the closed position and the second plate. This means that here too there is an "and / or" between transmittable tensile forces in the first and second direction, although the transmission in the second direction depends on the connection ensured by the locking mechanism, i.e. whether this connection exists or is broken. Of course, the transmission of forces parallel (or antiparallel) to the third direction is also conceivable. To be more precise, the direction information means that the transmittable forces have such directional component(s) or act in the said direction(s), whereby the overall resulting tensile force can be a corresponding superposition of the individual forces.The second receiving element can be secured, for example, with second fastening elements (e.g., screws or rivets) that can be arranged outside the second receiving openings, i.e., they do not need to be arranged in the second receiving opening. The fastening can, if necessary, be detachable.

[0073] However, variants are also conceivable in which the respective second receiving element is glued for fastening, for example.

[0074] The respective "corresponding" second receiving element is to be understood as being designed to correspond to the second end section with regard to the possible arrangement of the second end section and the interaction with the specific movable locking mechanism. Typically, a certain form-fitting connection can also be provided between the second receiving element and the second end section. This means that the geometry of the respective second receiving element can be optimally matched to the geometry of the second end section with its movable locking mechanism of the respective connector, wherein desired tolerances can also be taken into account if necessary.

[0075] With regard to the design of the locking mechanism as a rotary latch, the second receiving element can in particular form the aforementioned engagement section for the latch element.

[0076] Like the first receiving element, the second receiving element also offers a number of advantages. Firstly, it offers a certain degree of independence from the respective plate thickness of the second plates. Due to the material used, the second receiving element has high mechanical stability and can be easily used even in thin plates. Only the second receiving openings need to be manufactured in the plates themselves – more complex geometries, which might be necessary for coordination with the movable locking mechanism, no longer have to be manufactured from the plate material.

[0077] The geometry of the second receiving opening is typically limited to a hole with a substantially circular cross-section or a substantially rectangular cross-section (possibly with rounded corners). The more complex geometries mentioned above, however, are formed by the second receiving element – ​​with corresponding mechanical stability.

[0078] The geometry of each second receiving element can also be adapted to different requirements—such as different movable locking mechanisms—with relatively little effort. The geometry of each second receiving opening can always remain the same, i.e., nothing needs to be changed on the plate manufacturing side, thus keeping additional costs to a minimum.

[0079] With regard to the corrosion resistance or corrosion protection of the second receiving element through the choice of material, stainless steel or coated steel, the statements made above in connection with the connector apply analogously.

[0080] Analogous to what was stated at the beginning, in a particularly preferred embodiment of the system according to the invention, the first plate and / or the second plate is / are made of plastic or composite material, in particular layered composite material. Advantages here include, in addition to the weight savings compared to metal plates, the easy processing, which is advantageous with regard to the production of the holders (whether with or without holder elements), and the wide variety of surface designs. It should be noted that "plastics" is also to be understood as meaning high-performance plastics.

[0081] SHORT DESCRIPTION OF THE CHARACTERS

[0087] WAYS OF IMPLEMENTING THE INVENTION

[0088] Fig. 1 shows a schematic plan view of a system according to the invention with a connector 1 according to the invention, a first plate 2 and a second plate 3, wherein for reasons of clarity only corner regions of the plates 2, 3 are shown (i.e. the plates 2, 3 generally have much larger dimensions than shown). In the illustrated embodiment, the plates 2, 3 are each made of a high-performance plastic. The plates 2, 3 have undersides 36, 36' with which the plates 2, 3 can typically be placed on a floor to be covered. Opposite the undersides 36, 36', the plates 2, 3 have top sides 37, 37' which can typically be driven over - even by heavy vehicles.

[0089] The connector 1 is arranged in a locking position 13 and connects the first plate 2 to the second plate 3.

[0090] Fig. 2 shows the corresponding sectional view along the section line AA shown in Fig. 1, which coincides with a longitudinal axis 15 of the connector 1, wherein the two upward-pointing arrows in Fig. 1 indicate the viewing direction.

[0091] The first plate 2 has a first receptacle 7 and the second plate 3 a second receptacle 10. The two plates 2, 3 are arranged next to one another such that the first receptacle 7 and the second receptacle 10 lie opposite one another. The arrangement of the plates 2, 3 is such that a certain plate spacing 28 exists between the plates 2, 3. When connecting with the connector 1, tolerances are permissible, which is why the said plate spacing 28 can range from zero (here the plates 2, 3 touch each other) up to a maximum permissible plate spacing without the connection being impaired. This range is indicated in Fig. 1 by the three dotted lines.

[0092] The connector 1 comprises a first end section 4 (see Fig. 2), a second end section 5 and a central section 6 arranged between and connecting the first end section 4 and the second end section 5, wherein the central section 6 is web-shaped in the illustrated embodiment. The central section 6 has an upper side 16 and a lower side 17 opposite the upper side 16 and extends parallel to a first direction 14, which is parallel to the longitudinal axis 15 of the connector 1 and points from the second end section 5 to the first end section 4.

[0093] The first end section 4 basically runs at least in sections with a directional component anti-parallel to a second direction 18 and / or with a directional component parallel to a third direction 19, in order to bring the connector 1 into the closed position 13 at least by pivoting the connector 1 once about at least one pivot axis 20 running parallel to the third direction 19 and in doing so to be able to produce a positive connection between the first end section 4 and the first receptacle 7 of the first plate 2 when the connector 1 is inserted with the first end section 4 at least in sections into the first receptacle 7, wherein the second direction 18 is normal to the first direction 14 and points from the underside 17 to the top side 16 of the central section 6 and wherein the third direction 19 is normal to the first direction 14 and to the second direction 18.In the illustrated embodiment, the course of the first end section 4 lies in a plane which is parallel to the longitudinal axis 15 and in which the longitudinal axis 15 lies, and has two kinks or bends, so that an essentially S-shape of the course results, cf. Fig. 2. The course of the first end section 4 is such that, viewed in the first direction 14, after the central section 6, which runs parallel to the first direction 14, the course of the first end section has a first bend of 90 ° "downwards" (away from the upper side 16 of the central section 6), so that the course after this first bend is exactly antiparallel to the second direction 18. This is followed by a second bend of 90 ° in the opposite direction, so that the course of the first end section 4 after the second

[0094] Bending is parallel to the first direction 14. The pivoting of the connector 1 about the pivot axis 20 is indicated in Fig. 3 by the curved, downward-pointing arrow, the connector 1 being shown in a released position.

[0095] The second end section 5 of the connector 1 generally has a movable locking mechanism in order to be able to produce a detachable connection with the second receptacle 10 of the second plate 3 when, in the closed position 13, the second end section 5 is at least partially arranged in the second receptacle 10. In the exemplary embodiment shown, the movable locking mechanism of the second end section 5 is designed as a rotary latch with a locking element 22 which can be rotated by means of an actuating element 21 about an axis of rotation 32 running parallel to the second direction 18. The locking element 22 can be rotated from an inserted position 26 into a closed position 27 and vice versa. When the locking element 22 is in the inserted position 26, the second end section 5 can be arranged at least partially in the second receptacle 10 or can be inserted into the second receptacle 10 - in particular by pivoting about the pivot axis 20.By rotating the locking element 22 from the insertion position 26 into the closed position 27, the detachable connection with the second receptacle 10 is established when, in the closed position 13, the second end section 5 is correspondingly arranged at least in sections in the second receptacle 10.

[0096] The second receptacle 10 accordingly has at least one engagement section 33 which is designed such that it is positively connected to the locking element 22 when the locking element 22 is arranged in the closed position 27. In the insertion position 26, in turn, the aforementioned positive connection between the locking element 22 and the engagement section 33 is not present and the second end section 5 can therefore be easily inserted into the second receptacle 10 or arranged therein at least in sections.

[0097] The locking element 22 is movably mounted with the actuating element 21 along the rotation axis 32, wherein a spring element 25 is provided in order to hold the locking element 22 with the actuating element 21 in position or to urge it into a specific position.

[0098] On the one hand, this spring loading of the actuating element 21 and the locking element 22 can serve to hold the locking element 22 at least in one of the two positions 26, 27 in such a way that a rotational movement is only possible when a minimum torque is applied. Accordingly, for example, a knob and a corresponding recess in which the knob can be arranged can be provided as parts of locking means (not shown), wherein, for example, the knob is connected in a rotationally fixed manner to the locking element 22 and the recess is connected in a rotationally fixed manner to the central section 6 or to a fixed section of the second end section 5. When the knob is arranged in the recess, the knob can then be moved out of the recess by targeted pressing parallel to the axis of rotation 32 and against the spring force of the spring 25, so that the rotation of the locking element 22 is not restricted.Conversely, the aforementioned minimum torque must be applied to rotate the locking element 22 without deliberately pressing it when the knob is arranged in the recess. This means that the spring element 25 can then form part of the locking means.

[0099] On the other hand, the mobility parallel to the rotation axis 32 ensures a certain flexibility or tolerance with regard to the exact arrangement of the connector 1, in particular of the locking element 22, relative to the second receptacle 10, in particular to the engagement section 33. This is because the locking element 22 can be displaced along the rotation axis 32, if necessary, against the spring force of the spring element 25, in order to bring the locking element 22 into the closed position 27 and to establish the positive connection with the engagement section 33. This, in turn, makes application easier for the user.

[0100] In the illustrated embodiment, the first end section 4 is made in one piece with the central section 6 from metal, preferably from stainless steel or coated steel. The second end section 5 is also made substantially from metal, preferably from stainless steel or coated steel, with a section of the second end section 5 adjoining the central section 6 being made in one piece with the central section 6. Viewed against the first direction 14, the second end section 5 initially runs with a 90° bend "downwards" (away from the top side 16 of the central section 6), so that after the bend the course is antiparallel to the second direction 18. A further section protrudes from this section, antiparallel to the first direction 14, which section holds the movable locking mechanism or the rotary latch and in which the actuating element 21 is mounted so as to be rotatable about the rotation axis 32.

[0101] In the illustrated embodiment, a first receiving element 9 made of metal, preferably made of stainless steel or coated steel, is provided to match the first receptacle 7 to the first end section 4, and a second receiving element 12 made of metal, preferably made of stainless steel or coated steel, is provided to match the second receptacle 10 to the second end section 5.

[0102] Specifically, the first receptacle 7 comprises a first receptacle opening 8 and the first receptacle element 9, the first receptacle opening 8 completely passing through the first plate 2 and being rectangular or almost square with rounded corners, the slightly longer sides of the rectangle being normal to the longitudinal axis 15. The first receptacle element 9 is arranged in sections in the first receptacle opening 8 and is supported with a section on the underside 36 of the first plate 2 in a form-fitting manner (cf. Fig. 2 and Fig. 3). The first receptacle element 9 is detachably fastened by means of two first fastening elements 23, which in the illustrated embodiment are formed by screws and are arranged outside the first receptacle opening 8 (cf. Fig. 1).The first receiving element 9 is shaped correspondingly to the first end section 4, so that in the closed position 13 the positive connection between the first end section 4 and the first receiving element 9 is provided.

[0103] For this purpose, in the illustrated embodiment, the first receiving element 9 has a plate-shaped section which is arranged in the region of the middle of the plate thickness in the first receiving opening 8. In the plate-shaped section, a rectangular insertion opening 34 (cf. Fig. 1) is provided, into which the first end section 4 can be inserted with a free leg of its S-shaped course in order to insert the first end section 4 section by section into the first receptacle 7, as is illustrated in Fig. 3. In this - released - position, the connector 1 only has to be pivoted about the pivot axis 20 (indicated by the curved arrow in Fig. 3) in order to be transferred into the closed position 13, in which the positive connection between the first receiving element 9 - and thus the first receptacle 7 - and the first end section 4 is provided.The positive connection is then provided between the free leg of the S-shaped profile of the first end section 4 and the plate-shaped section of the first receiving element 9, as illustrated in Fig. 2. Analogously, the second receptacle 10 comprises a second receiving opening 11 and the second receiving element 12, wherein the second receiving opening 11 completely penetrates the second plate 3 and is rectangular with rounded corners, wherein the significantly longer sides of the rectangle run parallel to the longitudinal axis 15. The second receiving element 12 is arranged in sections in the second receiving opening 11 and is supported with a section on the underside 36' of the second plate 3 in a form-fitting manner (cf. Fig. 2 and Fig. 3). By means of two second fastening elements 24, which in the illustrated embodiment are formed by screws and are arranged outside the second receiving opening 11 (cf. Fig.1), the second receiving element 11 is detachably fastened. The second receiving element 11 is shaped to correspond to the second end section 5 with its rotary lock, so that in the closed position 13 on the one hand the arrangement of the second end section 5 at least in part in the second receptacle 10 is possible and on the other hand the detachable connection between the second end section 5 and the second receptacle 10 or the second receiving element 12 can be made by means of the rotary lock. Furthermore, in the illustrated embodiment a certain positive connection is provided or possible between the section of the second end section 5 running antiparallel to the second direction 18 and the second receiving element 12.

[0104] For this purpose, in the illustrated embodiment, the second receiving element 12 has a plate-shaped section which is arranged approximately in the region of the middle of the plate thickness in the second receiving opening 11. In the plate-shaped section, a rectangular insertion opening 35 (cf. Fig. 1) is provided, into which the second end section 5 is inserted with its section running antiparallel to the second direction 18 and with the section in the insertion position 26.

[0105] Locking element 22 can be inserted in order to arrange the second end section 5 in sections in the second receptacle 10, as illustrated in Fig. 2, the insertion position 26 being indicated only by dashed lines. When the locking element 22 is then rotated from the insertion position 26 into the closed position 27, a positive connection is produced between the locking element 22 and the plate-shaped section of the second receptacle element 12 or the engagement section 33 which is formed by the plate-shaped section of the second receptacle element 12.

[0106] In the first plate 2, a recess 31 is provided on the upper side 37 for the central section 6 of the connector 1, so that the connector 1 protrudes little or not at all beyond the upper side 37 of the first plate 2 in the closed position 13. Likewise, in the second plate 3, a recess 31' is provided on the upper side 37' for the central section of the connector 1, so that the connector 1 protrudes little or not at all beyond the upper side 37' of the second plate 3 in the closed position 13.

[0107] The positive connection between the first end section 4 and the first receptacle 7 or the first receptacle element 9 allows both a tolerance 29 in the first direction 14 and a tolerance 30 in the second direction 18, as illustrated in Fig. 2, the tolerances 29, 30 existing between the connector 1 in its shown closed position 13 and a closed position indicated by dashed lines. The second end section 5 with the rotary lock can assume correspondingly different positions in the second receptacle element 12 with the insertion opening 35. A certain tolerance in the third direction 19 is also conceivable in principle.Specifically, in the illustrated embodiment, a tolerance in the third direction 19 is provided by the fact that in the closed position 13 there is a certain distance between the first end section 4 and the edges of the insertion opening 34 running parallel to the first direction 14, as well as a certain distance between the second end section 5 and the edges of the insertion opening 35 running parallel to the first direction 14. Due to the tolerances mentioned, in particular the tolerances 29, 30, the requirements for accuracy when laying the panels 2, 3 are lower than in solutions known from the prior art. Furthermore, temperature-induced expansions and contractions of the connector 1 - but also of the panels 2, 3 - do not impair the connection.

[0108] In summary, in the illustrated embodiment, the first plate 2 and the second plate 3 can be connected to each other extremely quickly and easily using the connector 1 as follows:

[0109] - Arranging the first plate 2 and the second plate 3 next to each other so that the first receptacle 7 and the second receptacle 10 are opposite each other;

[0110] - section-by-section insertion of the first end section 4 into the first receptacle 7, wherein the free leg of the S-shaped profile of the first end section 4 is inserted into the insertion opening 34;

[0111] - Transferring the connector 1 into the closed position 13, wherein the transfer comprises a one-time pivoting of the connector 1 about the pivot axis 20 running parallel to the third direction 19 or essentially consists of said pivoting, wherein during the transfer into the closed position 13 a positive connection with tolerance at least in the first direction 14 and the second direction 18 is produced between the first end section 4 and the first receptacle 7 and wherein during the transfer into the closed position 13 the second end section 5 is inserted at least in sections into the insertion opening 35 and is thus arranged at least in sections in the second receptacle 10;

[0112] - Establishing the detachable connection between the second end section 5 and the second receptacle 10 by actuating the movable locking mechanism of the second end section 5, wherein the locking element 22 is rotated from the insertion position 26 into the locking position 27.
