Description

[0001] The invention relates to a container for storing and transporting objects.

[0002] Various containers for transporting objects are known from the prior art. For example, EP 2 799 355 A2 describes a plastic container having a running rim on its base with an inner, outer, and central rim, the outer rim being arranged outside the central rim. A first running surface is provided in the form of an underside of the central rim, on which the container can stand and slide on a surface. In addition to the first running surface, the base further has a second running surface, the second running surface extending from the outer corners of the outer rim to the first running surface. The second running surface is raised relative to the inner and outer rims. The second running surface ensures that the noise associated with rolling is minimized, even if the container rolls diagonally over the transport rollers of a transport system.

[0003] The invention is based on the object of providing an improved container for storing and transporting objects, in particular to reduce noise during movement of the container. The object underlying the invention is achieved by the features of the independent patent claim. Preferred embodiments of the invention are specified in the dependent patent claims.

[0004] A container for storing and transporting objects is proposed. The container has a base that defines a loading space of the container at the bottom, and side walls that extend upward from the base. The base defines a horizontal running surface for the container to slide along a surface. Furthermore, the base has an elastic jack arranged on an outer edge of the base. The jack has a bottom side that extends toward an outer edge of the jack and has a particularly constant angle to the horizontal running surface.

[0005] For the purposes of the description, the term "running surface" is understood to mean, in particular, that surface of the container with which the container can stand at least partially on the ground. In addition to the running surface, it is in principle possible for the container to have one or more further running surfaces. For the purposes of this disclosure, it is assumed, for example, that the ground runs horizontally or, in the case of a gravity-driven roller conveyor, slightly inclined downwards. The running surface is therefore aligned parallel to the ground when the container is standing on the ground or is moving on it. The outer edge of the base refers, in particular, to a region of the base in which the side walls meet the ground from above.

[0006] To ensure the jack can move freely upwards relative to the running surface, the jack has, for example, an upper surface that is exposed at the top. The outer edge of the jack connects the upper surface to the underside of the jack. The outer edge of the jack is advantageously rounded.

[0007] Because the underside of the jack is at an angle to the horizontal running surface, the jack as a whole can float freely above the ground when the container is moved across the ground. The container can slide or be moved by roller conveyors. In the latter case, the rollers can be motor-driven, or the transport can be gravity-driven, so that the container rolls or slides down over the rollers under the force of gravity. The angle between the underside of the jack and the running surface now allows the underside of the jack to act as a contact surface for the jack to collide with obstacles on the ground.

[0008] In extreme cases, the obstacles can be edges that protrude from the surface. Typically, the obstacles are formed by at least some or all of the rollers, the upper edge of which the jack will first gently touch, especially when the container is fully loaded. The reason why the jack touches the surface here first and, due to its slope, does not remain rigidly above the running surface formed by the rollers (the surface) is that, for example, the container, due to its elasticity, will not behave as rigidly when loaded. The container could "deform" to such a small extent that, in reality, the underside of the jack first gently touches the next roller, and only then does the actual running surface of the container come into contact with the running surface formed by this roller.It should be noted here that there is also a distance between the rollers, which could promote a slight deformation of the container bottom in this area, so that the partially "hanging in the air" of the jack could also promote the deformation of the container and its inclination could promote the gentle running onto the next roller.

[0009] It's also possible that obstructions could result from rollers mounted at different heights. This could be due to manufacturing tolerances or wear on the roller bearings.

[0010] The larger the impact surface, the greater the likelihood that obstacles will strike the impact surface, and such impacts can be gently absorbed by an upwardly spring-loaded movement of the jack. Such gentle absorption of impacts by an upward bend of the jack could enable the bottom of the container to bounce gently against the obstacles. This can reduce the noise generated when the container hits the obstacles. Accordingly, a larger impact surface can more often reduce the noise generated when the container hits the obstacles. It has proven particularly practical if the angle between the underside of the jack and the running surface is at least 3 degrees, in particular in a range between five and ten degrees, and more particularly five to seven degrees.

[0011] For example, a first groove is provided between the running surface and the jack to promote elastic bending of the jack upwards relative to the running surface. According to one possible embodiment, the first groove can be designed in the form of a U- or V-shaped notch. In any case, the first groove represents an elongated recess on an underside of the base. The first groove preferably extends at least parallel to a first side wall of the side walls and thus parallel to a first outer edge of the base. The underside of the jack is delimited, in particular, towards the running surface by the first groove and on the other side by the outer edge. In general, the angle between the underside of the jack and the horizontal running surface can be measured or defined from the position of the first groove. The angle does not have to be constant, but can, for example, increase steadily starting from the first groove up to a certain value.In principle, the first groove can be straight or run in a serpentine or zigzag pattern parallel to the first outer edge of the base. However, a main extension direction of the first groove is generally parallel to the first outer edge of the base.

[0012] By providing the first groove, a thinning of the material occurs in an area of ​​the floor surrounding the first groove, allowing the jack to be bent upwards more easily relative to the running surface. Furthermore, the first groove can define a first axis of rotation around which the jack can be bent.

[0013] Advantageously, a floor material in the immediate vicinity of the first groove has a lower modulus of elasticity than in areas of the floor farther away from the first groove. As a result, the floor material located in the immediate vicinity of the first groove can be deformed more easily than the material farther away from the first groove. In particular, a targeted selection of the modulus of elasticity of the material in the immediate vicinity of the first groove can be used to adjust the spring stiffness of the jack.

[0014] In principle, however, the spring properties of the jack can also be adjusted by the shape and size of the cross-section of the first groove. It has proven particularly advantageous if the first groove has a cross-section essentially in the shape of a triangle along its longitudinal extent. This could enable simple production of the first groove. The corners of the triangle can be rounded to facilitate production of the first groove. Furthermore, the rounded corners of the triangle can also prevent stress peaks.

[0015] According to one embodiment, the jack is formed by a lateral, in particular U- or V-shaped, recess in the floor. The recess has a bottom side that forms the top side of the jack. Furthermore, the recess has an top side that is arranged above the bottom side of the recess, and a transition region that connects the bottom side to the top side of the recess. In this embodiment, the first groove is arranged below the transition region, wherein the transition region has approximately the same distance as the first groove from an outer edge of the jack extending away from the cargo space. This edge of the jack has, in particular, the above-mentioned outer edge of the jack.

[0016] Because the transition area is approximately the same distance from the outer edge of the jack as the first groove, both the top and bottom of the jack are exposed from a connecting area of ​​the base that connects the transition area of ​​the recess to the first groove. This causes the jack as a whole to protrude from the connecting area and thus to function like a spiral spring that begins in the connecting area. In other words, the first groove below the transition area minimizes the material of the base in such a way that the material of the base extending outwards from the transition area or the first groove can be bent upwards like a spiral spring, in particular with an approximately constant cross-section. The connecting area between the first groove and the transition area of ​​the recess essentially marks a first end of the jack in the form of a spiral spring.

[0017] If the first groove were positioned further inward than the transition area of ​​the recess, the material cross-section of the base below the transition area of ​​the recess would be larger. This would significantly increase the stiffness of the first end of the jack. A section in which the jack would act as a bending spring with a nearly constant cross-section would be shifted further outward in this case. This would stiffen the jack as a whole. This effect can be reduced by locating the first groove below the transition area of ​​the recess.

[0018] A cross-section of the spiral spring, ie of the jack, can be influenced by the cross-section of the first groove, in particular in an initial region of the jack, which extends approximately from the connecting region to a first third of the jack.

[0019] In order to make the cross-section of the jack as homogeneous as possible, especially in the initial area, it has proven advantageous for the cross-section of the first groove to be in the shape of an irregular triangle. The irregular triangle has a first, second, and third side, wherein the first side of the triangle is aligned parallel to the tread, the second side of the triangle is arranged closer to the outer edge of the jack than the third side of the triangle, and the second side of the triangle is longer than the third side of the triangle.

[0020] In particular, the length of the underside of the jack from the outer edge to the end of the first groove facing the jack is at least half, preferably at least two-thirds of the length from the outer edge to the end of the first groove facing away from the jack. In a further variant, the length of the underside of the jack from the outermost end of the jack facing away from the groove to the end of the first groove facing the jack is at least half, preferably at least two-thirds of the length from the outermost end of the jack facing away from the groove to the end of the first groove facing away from the jack.

[0021] In particular, if the cross-section of the first groove has the shape of an irregular triangle, for example, the length of the underside of the jack from the outer edge to the end of the first groove facing the jack, the end of the first groove facing the jack being defined by the point between the first and second sides of the irregular triangle, is at least half, preferably at least two-thirds of the length from the outer edge to the end of the first groove facing away from the jack, the end of the first groove facing away from the jack being defined by the point between the first and third sides of the irregular triangle.

[0022] Because the second side of the triangle is longer than the third side of the triangle, a cross-section of the initial area of ​​the jack can run approximately constantly along a direction from the groove to the outer edge of the jack. This makes it possible to enlarge a section within which the jack behaves like a bending spring, in particular like a bending spring with a cross-section that is constant over its length. This could make it easier to bend the jack upwards, thus reducing noise generated by the container when the jack hits an obstacle. Furthermore, this could make it easier to calculate upward deformation of the jack, enabling a simple design of the jack.

[0023] According to one embodiment, the jack completely surrounds the running surface. This could make it possible to dampen the impact of the container on obstacles regardless of the direction in which the container moves toward them. For example, the container can be placed anywhere on the roller conveyors; a portion of the jack would always strike a roller striking the container or an obstacle in general. Thus, noise reduction can occur even if the container is moved from a desired position on the roller conveyors.

[0024] An advantageous development of this embodiment provides that the first groove completely surrounds the running surface. This can make it easier to bend up the jack that completely surrounds the running surface in any area of ​​the outer edge of the container. In this development, the first groove extends, for example, around the entire base along an outer edge of the base that runs around the entire base and also contains the first outer edge. In particular, the first groove always runs parallel to the respective side wall of the side walls that abuts the respective part of the outer edge that runs around the entire base. The running surface is preferably centered in the middle of the base of the container and is symmetrically surrounded on all sides by the first groove.

[0025] In a further embodiment, the jack has second grooves which extend, in particular completely, from the first groove to the outer edge of the jack extending away from the loading space. The second grooves could enable the jack to be bent in a further bending direction in addition to a possible bending direction predetermined by the first groove. Just as the first groove can define the axis of rotation about which the jack can be at least partially bent, the second grooves can also each define a respective further axis of rotation about which the jack can be at least partially bent. The respective further axis of rotation runs parallel to the respective second groove. In this case, it is advantageous if the second grooves extend completely from the first groove to the outer edge of the jack extending away from the loading space.The mobility of the jack around the respective additional axis of rotation can thus be increased even further.

[0026] Because the jack is at least partially bendable around the first axis of rotation and additionally around the respective additional axis of rotation, the jack can dampen the impact of obstacles located on the ground that strike the container at an angle, in particular at an angle relative to the first outer edge of the floor. This can also reduce noise emissions in such a case if the container strikes a roller of the roller conveyor at an angle. For this purpose, the jack does not have to completely surround the running surface, as described above for a possible embodiment of the container.

[0027] In general, an oblique impact on the jack can be dampened particularly well if the direction of impact is perpendicular to the respective further axis of rotation, ie perpendicular to the respective second groove.

[0028] According to a further development of the previous embodiment, the second grooves run perpendicular to the first groove. This also allows the impact of a roller on the jack to be better dampened with the help of the jack when the roller approaches the container in a direction parallel to the first groove. In this case, the direction of impact of the roller would run perpendicular to the second grooves. Since the second grooves enable the jack to bend, in particular around the respective further axis of rotation, which runs parallel to the respective second groove, the jack can better dampen the noise emissions of the container in collisions in which the direction of impact of the roller runs perpendicular to the second grooves.

[0029] In particular, in the event that a corner of the floor encounters the obstacle when the container is arranged at an angle to a transport direction of the container on the roller conveyors, it is particularly practical if a corner segment of the jack is defined by a pair of second grooves, in particular perpendicular to one another. By providing the corner segment, a damping element of the container floor could be realized, especially at the corner of the floor, which can dampen impacts from multiple directions.

[0030] Advantageously, such a corner element is arranged in each corner of the container. The container is preferably rectangular.

[0031] Advantageously, the second grooves are each formed by an extension of the first groove. This could facilitate the manufacture of the second grooves.

[0032] Preferred embodiments of the proposed container are explained in more detail with reference to the following figures. The following schematically shows: Figure 1 shows a container for transporting objects with a jack arranged on a bottom of the container; Figure 2 shows rollers of a roller conveyor for transporting the Figure 1 shown container; Figure 3 shows another variant of the container shown in Figure 1 shown jack with a first groove; Figure 4 shows another variant of the Figure 1 shown jack; Figure 5 a further development of the Figure 4 shown variant of the Figure 1 shown jack; Figure 6 a further development of the Figure 5 shown variant of the Figure 1 shown jack; Figure 7 a view from below of the Figure 1 shown bottom of the container and the Figure 2 shown rollers; Figure 8 a view from below of another variant of the Figure 1shown bottom with a circumferential first groove and second grooves;

[0033] Fig. 1 shows a container for storing and transporting objects. The container 1 has a bottom 2, which defines a loading space 3 of the container 1 at the bottom, and side walls extending upwards from the bottom 2. The side walls comprise a first side wall 4.1, a second side wall 4.2 and two further Fig. 1 invisible side walls.

[0034] The base 2 defines a horizontal running surface 5 for the sliding of the container 1 on a surface, which is not shown in the figures for the sake of clarity. The running surface 5 can be defined, for example, by one or more running rings, as described in EP 2 799 355 A2. The running surface 5 can, for example, have an inner running ring, a middle running ring surrounding the inner running ring, and an outer running ring surrounding the middle running ring.

[0035] The horizontal running surface 5 is suitable for sliding the container 1 on a flat surface, i.e. on a continuous flat surface. Furthermore, with the help of the horizontal running surface 5, it is possible to move the container 1 over rollers 20, which are arranged in Fig. 2are shown. In this case, upper visible edges 22 of the rollers can lie in a transport plane 23 of the container 1. In this case, the background can be defined by the upper visible edges 22. The upper visible edges 22 are visible in particular in a viewing direction that is the same as a transport direction 21 of the container 1 on the rollers 20 in the transport plane 23. The rollers 20 can, for example, be driven by motors of roller conveyors. The roller conveyors can be regarded as part of a transport system for containers, in particular for the container 1. The rollers 20 comprise at least a first roller 20.1, a second roller 20.2 and a third roller 20.3.

[0036] As in Fig. 1As shown, the base 2 has an elastic jack 6 arranged on an outer edge of the base. The jack 6 has a bottom 7 which extends towards an outer edge 8 of the jack 6 and has an angle 9 to the running surface 5. The angle 9 is preferably 5 to 10 degrees. Fig. 1 In the embodiment shown, the jack 6 runs parallel to a first outer edge of the base 2, which runs parallel to the first side wall 4.1.

[0037] In principle, it is possible for the outer edge 8 of the jack 6 to protrude horizontally beyond the first side wall 4.1. However, this would have the disadvantage that, when placing several containers one behind the other, including the container 1, additional space would be required for a portion of the jack 6 protruding beyond the first side wall 4.1. For this reason, without limiting the generality, the figures only show variants in which the outer edge 8 is flush with the first side wall 4.1 in the vertical direction, i.e., does not protrude horizontally beyond the first side wall 4.1.

[0038] Fig. 1 and 3 to 6each show a design in which the jack 6 is formed by a lateral, in particular U-shaped recess 30 of the base 2. The recess 30 has a bottom side 31, which forms an upper side 11 of the jack 6. Furthermore, the recess 30 has an upper side 32, which is arranged above the bottom side 31 of the recess 30. Furthermore, the recess 30 is formed by a transition region 33, which connects the bottom side 31 with the upper side 32 of the recess 30. The transition region 33 is in the Figures 3 to 6 marked with dashed lines.

[0039] Due to the recess 30, the upper side 11 of the jack 6 can move upwards if the lower side 7 of the jack 6 is pushed upwards by an obstacle located in the transport direction 21. In the Fig. 3In the embodiment of the container 1 shown, the upper side 11 of the jack 6 forms part of the underside 31 of the recess 30. The upper side 11 is therefore at least partially formed by the underside 31 of the recess 30.

[0040] The obstacle can be an unevenness of the flat surface mentioned above or simply the top of a roller. In the latter case, the "obstacle" is represented in the form of one of the Fig. 2 illustrated upper edges 22 of the rollers 20, for example in the form of the upper edge of the third roller 20.3. The upper edge of the third roller 20.3 can, for example, represent the obstacle in the transport direction 21 if the third roller 20.3 is arranged slightly offset upwards in the vertical direction in relation to the other rollers of the rollers 20, ie the first roller 20.1 and the second roller 20.2. In this case, the upper edge of the third roller 20.3 would be above the Fig. 2The third roller 20.3, which is offset vertically upwards, is indicated by the dashed circle in Fig. 2 In this case, the underside 7 of the jack 6 can act as a striking surface when the container 2 moves in the transport direction 21 toward the third roller 20.3.

[0041] In practice, however, it will be the case that due to internal deformations of the container and the Figure 2 At the distance between the rollers shown, the outer edge of the container will be lowered vertically downwards if the running surface or outer edge overhangs one of the rollers in the transport direction. As a result, the underside 7 of the jack will gently roll onto the next roller.

[0042] In a Fig. 3In the illustrated state of the container 1, the running surface 5 rests on the first roller 20.1 and the second roller 20.2 and moves towards the third roller 20.3, which is offset upwards relative to the rollers 20.1 and 20.2 for illustration purposes. A vertical offset 34 of the third roller 20.3 relative to the two rollers 20.1 and 20.2 is shown in Fig. 3 exaggerated to illustrate that the upper edge of the third roller 20.3 lies above the transport plane 23.

[0043] When the underside 7 of the jack 6 strikes the obstacle on the ground, for example the third roller 20.3, the tongue 6 is moved upwards. When the jack 6 moves upwards, the jack 6 moves in particular relative to a first region 35 of the floor 2, which is arranged above the running surface 5 and is located further inside the floor 2 than the jack 6. A movement of the jack 6 relative to the first region 35 results in particular in a deformation of a connecting region 36, which connects the first part 35 of the floor 2 to the jack 6. The connecting region 36 is shown in the form of a rectangle for the sake of simplicity.

[0044] It goes without saying that the connecting area 36 can also extend further into the interior of the base 2 than is possible in Fig. 3It is crucial, for example, that the connecting region 36 comprises material that deforms due to the upward movement of the jack 6 relative to the first region 35. Deformation of the connecting region 36 makes it possible to absorb the impact energy that is absorbed by the jack 6 when the underside 7 collides with the obstacle.

[0045] To make the jack 6 more elastic, a first groove 40 can be provided between the jack 6 and the running surface 5. The term "more elastic" means that the jack 6 can be bent upwards more easily. This can be achieved in particular by thinning a material of the base 2 in an area between the jack 6 and the running surface 5, in particular the first part 35 of the base 2. Such a thinning can be achieved in particular with the aid of the first groove 40. Due to the first groove 40, the Fig. 3 illustrated connection area 36, ​​within which the material of the floor 2 can deform. The less material is available within the connection area 36, ​​the more this material must deform in order to absorb the same energy for dampening the impact of the underside 7 of the jack 6 with the obstacle.

[0046] Fig. 4shows an advantageous further training especially in Fig. 3 illustrated embodiment of the container 1. In this further development, the first groove 40 is arranged below the transition region 33. The transition region 33 has approximately the same distance 41 as the first groove 40 from an outer edge of the jack 6 extending away from the loading space 3. In most cases, the outer edge of the jack 6 extending away from the loading space 3 is formed by the outer edge 8 of the jack 6.

[0047] The fact that the first groove 40 is arranged below the transition area 33 results in the following advantages. Firstly, the connecting area 36 is enlarged, since the distance between the underside 31 and the first groove 40 is smaller than in Fig. 3 This could, among other things, increase the stability of the connecting area 36 and thus the service life of the jack 6. In the case of the Fig. 3In the variant shown, in which the first groove 40 is arranged closer to the outer edge 8 than the transition region 33, a smaller distance between the uppermost point of the first groove 40 and the underside 31 of the recess 30 results. As a result, the connecting region 36 in the Fig. 3 shown variant is smaller than the one in Fig. 4 illustrated embodiment of the container 1.

[0048] Furthermore, an initial region 42 of the jack 6 can take on a shape similar to a spiral spring if the first groove 40 is arranged below the transition region 33. The initial region 42 of the jack 6 is in Fig. 4The maximum thickness of the jack 6 is, within the initial area 42, sometimes twice to three times as large as the minimum thickness of the jack 6 within the initial area 42 of the jack 6. However, it is possible to calculate an upward deformation of the jack 6 using Hooke's law. For example, a linear progression from the minimum thickness of the jack 6 to the maximum thickness of the jack 6 can be assumed. Fig. 4 and Fig. 3 It can be seen that a range within which a deformation of the jack 6 behaves similarly to a bending spring, in which Fig. 4 shown variant of the container 1 is larger. This allows, on the one hand, the upward deformation of the jack 6 to be calculated more easily, and, on the other hand, to make the jack 6 more elastic as a whole.

[0049] At the Fig. 4In the illustrated embodiment of the first groove 40, the first groove 40 has a cross-section substantially in the shape of a triangle along its longitudinal extent. The longitudinal extent of the first groove 40 runs parallel to the outer edge 8 or to the first side wall 4.1.

[0050] Fig. 5 shows a further advantageous further training especially in Fig. 4 illustrated variant of the first groove 40, in which the cross section of the first groove 40 along its longitudinal extent is formed in the form of an irregular triangle 50. The irregular triangle 50 has a first side 51, which is aligned parallel to the tread 5, and a second side 52, which is arranged closer to the outer edge 8 of the jack 6 than a third side 53 of the triangle 50. Furthermore, in the Fig. 5shown irregular triangle 50, the second side 52 is longer than the third side 53. This causes, for example, that the second side 52 is at least partially parallel to the surface 31 in the Fig. 5 shown cross section of the base 2. As a result, the thickness of the jack 6 can be approximately constant within the initial region 42, at least in a region above the first groove 40. This results in a property of the jack 6 in the initial region 42 that approximately corresponds to a bending spring with a constant thickness over its length. For the sake of clarity, the triangle 50 is shown below the first groove 40 in Fig. 5 However, the triangle 50 is intended to represent the cross section of the first groove 40 in the Fig. 5 represent the cross-section of the floor 2 shown.

[0051] Fig. 6 shows a further improvement in the particularly in Fig. 4illustrated variant of the first groove 40, in which the second side 52 of the irregular triangle 50 runs substantially parallel to the underside 31 of the recess 30. This achieves a nearly constant thickness of the jack 6 in the initial region 42 of the jack 6.

[0052] Fig. 7 shows the floor 2 from the underside. Furthermore, Fig. 7 the container 1 in a state in which the container 1 moves in the transport direction 21 on the first roller 20.1 and the second roller 20.2. Accordingly, the two rollers 20.1, 20.2 cover parts of the base 2 during the Fig. 7 shown view. Fig. 7further shows an embodiment of the container 1 in which the jack 6 completely surrounds the running surface 5. Furthermore, the first groove 40 completely surrounds the running surface 5. This has the advantage that the jack 6 can absorb shocks from all directions in a plane that runs parallel to the running surface 5. This is advantageous, for example, when the container 1 is arranged rotated relative to the transport direction 21, as shown in Fig. 7 shown. In this case, a corner of the container 1 would first strike the third roller 20.3. Because the jack 6 completely surrounds the running surface 5, a part of the jack 6 is also arranged at the corner of the container 1, in particular at the corner of the base 2, at which the container 1 first strikes the third roller 20.3. The part of the jack 6 located at the corner can move upward to dampen a shock between the third roller 20.3 and the corner of the base 2.

[0053] Fig. 8 shows a further embodiment of the container, in which the jack 6 has second grooves 80. The second grooves 80 extend from the first groove 40 to an outer edge of the jack 6 extending away from the loading space 2. Fig. 8 shows in particular a variant in which the second grooves 80 extend completely to the outer edge of the jack 6 extending away from the loading space 2.

[0054] The first groove 40 is in Fig. 7 and Fig. 8 represented by three solid lines. These three lines can each be connected to a corner of the Fig. 5 shown triangle 50. Accordingly, the second grooves 80 are also indicated by three solid lines in Fig. 8 shown. Fig. 8 shows how Fig. 7a view from below of the base 2. Advantageously, a respective corner segment 81.1, 81.2, 81.3, 81.4 of the jack 6 is defined by a pair of second grooves 80, in particular perpendicular to one another. Fig. 8 shows a variant according to which the container 1 is rectangular and in each corner of the container 1 such a corner segment 81.1, 81.2, 81.3, 81.4 is arranged.

[0055] The corner segments 81 now have the advantage that they can be bent upwards in different directions even more flexibly than corners of the Fig. 7 shown variant of the jack 6. This could be due, on the one hand, to the fact that when one of the corner segments 81 is deformed, the material of the respective corner segment can be deformed more easily if at least one of the second grooves 80 provides space for the respective deformation.

[0056] In Fig. 5Furthermore, a pivot point 54 is shown, around which the jack 6 essentially rotates when the jack 6 is bent upwards. Fig. 5 a cross-sectional drawing of the floor 2, the Fig. 5 The pivot point 54 shown has a first axis of rotation 91 as shown in Fig. 8 shown, around which the jack 6 can bend. The first axis of rotation 91 runs parallel to the first groove 40. In particular, the first axis of rotation 91 is defined by the first groove 40.

[0057] In an analogous manner, the second grooves 81 can now each define a further axis of rotation around which the jack 6, which completely surrounds the running surface 5, can be bent. For example, a Fig. 8The horizontal groove of the second grooves 80 shown in the image, which forms the first corner segment 81.1, defines a second rotation axis 92 about which the jack 6, in particular the first corner segment 81.1, can bend. Since the first corner segment 81.1 can be bent both about the first rotation axis 91 and about the second rotation axis 92, the first corner segment 81.1 can in principle also be bent about any rotation axes that are in the image plane of the Fig. 8 Any axes of rotation can be understood as "linear combinations" of a vectorial representation of the first axis of rotation 91 and the second axis of rotation 92.

[0058] It goes without saying that the undersides of the corner segments 81 also form an angle to the tread 5. This angle is also preferably five to ten degrees. Advantageously, the second grooves 80 are each formed by an extension of the first groove 40. List of reference symbols
