Description

[0001] The present invention relates to a bearing element for connecting at least one roller, at least one roller arrangement and / or at least one wheel to a supporting structure of at least one container, comprising at least one base element and at least one locking block insertable into at least one opening of the supporting structure, wherein the locking block is mounted rotatably about a first axis of rotation extending in a first direction relative to the base element, as well as a roller and / or roller arrangement comprising such a bearing element.

[0002] In freight transport, containers are predominantly used to transport goods. These containers are standardized, for example, according to ISO 668 and / or ISO 1496. This standardization ensures that the handling equipment and means of transport used to transport and move the containers are adapted to the containers. This applies not only to the external dimensions of the containers, but also to the interfaces to the handling equipment, such as fastening and / or connection interfaces. These interfaces are also standardized, for example, according to ISO 1161 with regard to corner fittings and corner blocks. These interfaces have, among other things, standardized openings into which fastening and / or handling elements or securing elements can engage.

[0003] For the transport of such containers over long distances, the containers can be placed on self-supporting transporters, tugs, trailers or ships with a loading area, whereby the containers are secured to the loading area or a self-supporting support structure and / or containers are secured to each other by connecting them via the interfaces.

[0004] However, there are also situations where containers need to be moved over relatively short distances or need to be movable without the need for a transporter with a self-supporting support structure. For these purposes, the container is connected to rollers, especially during lifting, using interfaces such as corner fittings.

[0005] Despite the standardization of the interfaces, they have comparatively large tolerances. This can lead to play between the interface and the caster. Such play can have a negative impact on the caster and its handling in various ways. This fundamentally reduces driving stability. Furthermore, the play in swivel casters leads to a tilting of the caster's pivot axis, which negatively affects the steering behavior. Furthermore, the play creates lines of freedom with regard to the position of the rolling axis in space. If, for example, this axis is not parallel to the ground due to tilting caused by the play, this can have a negative impact on tracking, which is particularly relevant for fixed casters.Furthermore, a play between the interface and the roller can lead to an increase in loads on the roller, in particular a fork and / or a wheel of the roller, if the roller has a caster, in particular if a pivot axis is skewed to a roll axis of a swivel roller, which can lead to an overload and thus a defect in the roller.

[0006] It is therefore an object of the present invention to provide a bearing element for a roller by which the disadvantages described above are avoided or at least reduced.

[0007] This object is achieved according to the invention in that the locking block is further longitudinally movable relative to the base element along at least one second direction, which has at least one directional component parallel to the first direction.

[0008] It is preferred that the container and / or the supporting structure is designed according to ISO 668 and / or ISO 1496 and / or comprises at least one corner block and / or corner fitting according to ISO 1161, in particular the opening is designed in at least one corner block and / or corner fitting according to ISO 1161.

[0009] It is also proposed that the first direction and / or the first axis of rotation run substantially perpendicular to a main plane of the support structure and / or the opening and / or parallel to a normal direction of the main plane of the support structure.

[0010] A bearing element according to the invention can be characterized in that in a first rotational position of the locking block about the first rotational axis, an insertion of the locking block, in particular into the opening, is possible, in particular until a surface of the base element comes into contact, at least in some areas, with a surface and / or underside of the support structure and / or the corner fitting.

[0011] Furthermore, it can be provided according to the invention that in at least one second rotational position of the locking block about the first rotational axis, a positive connection of the locking block, the base element and / or the bearing element with the support structure can be established, a movement of the locking block, the base element and / or the bearing element in the second direction is limited and / or a movement of the locking block through the opening is prevented.

[0012] Preferred embodiments provide that the base element has at least one elevation, wherein the elevation preferably has a peripheral shape that is complementary to an inner side of the opening at least in some areas, in particular limiting and / or preventing rotation when the elevation is arranged at least in some areas in the opening.

[0013] A bearing element according to the invention can be characterized by at least one first actuating element by means of which the locking block can be rotated about the first axis of rotation and / or at least one second actuating element by means of which the locking block can be moved in the second direction, in particular against a prestressing element comprising at least one, preferably at least one compression spring.

[0014] In the aforementioned embodiment, it is preferred that the first actuating element comprises at least one handling element that is at least indirectly connected to the locking block in a rotationally secure manner and / or is arranged captively and / or permanently on the bearing element and / or the first actuating element, and / or that the locking block protrudes at least partially through the first actuating element and / or the first handling element and / or is movable relative to the first actuating element and / or the first handling element along the second direction.

[0015] In the two aforementioned embodiments, it is preferred that the second actuating element comprises at least one second handling element, which is preferably arranged and / or can be arranged in a captive and / or permanent manner on the bearing element and / or the second actuating element, wherein the second actuating element and / or the second handling element is / are mounted rotatably relative to the base element and / or the locking block, in particular rotatably about the first axis of rotation.

[0016] It is also proposed that the locking block, on the one hand, and the second actuating element and / or the second handling element, on the other hand, are connected to one another by means of at least one threaded connection, wherein, in particular, a movement of the locking block along the second direction, in particular relative to the base element, the first actuating element, and / or the first handling element, can be generated by a movement of the second actuating element and / or second handling element relative to the locking block, and / or a position of the second handling element relative to the remaining area of ​​the second actuating element, in particular the threaded connection, can be changed, optionally by releasing a connection of the second handling element with the remaining area of ​​the second actuating element, in particular the threaded connection,and reconnecting the second handling element to the remaining area of ​​the second actuating element, in particular the threaded connection, in a different position, in particular relative position to the threaded connection.

[0017] Furthermore, it is preferred that the first actuating element and / or the first handling element is arranged at least in regions on a side of the base element facing away from the locking block, and / or that the locking block protrudes at least in regions through the base element.

[0018] It is also proposed that the first actuating element and / or the first handling element is arranged at least in regions between the base element and the second actuating element and / or the second handling element.

[0019] Furthermore, a bearing element according to the invention can be characterized in that the first handling element and / or the second handling element comprises at least one lever, handle, rod and / or adjusting wheel, in particular rotatable about the first axis of rotation.

[0020] It is also proposed that the bearing element comprises at least one locking element for locking the first actuating element, the first handling element, the second actuating element and / or the second handling element in at least one position, preferably a plurality of positions, in particular a position corresponding to the first position of the locking block, the second position of the locking block and / or the position of the locking block with reduced and / or removed play.

[0021] For the aforementioned embodiment, it is also proposed that at least one first locking element for locking the first actuating element and / or the first handling element and / or at least one second locking element for locking the second actuating element and / or the second handling element and / or the locking element, the first locking element, and / or the second locking element comprise at least one latching device, clip device, ball latch and / or clamping device.

[0022] Furthermore, the invention provides a roller and / or roller arrangement comprising at least one bearing element according to the invention.

[0023] It is proposed for the roller that the roller comprises at least one fork connected to the bearing element and at least one wheel mounted in the fork so as to be rotatable about a first rolling axis, in particular which can be brought into contact with a ground.

[0024] It can be provided that the roller is designed as a fixed roller, in particular the fork is connected to the bearing element in a rotationally secure manner.

[0025] Alternatively, it is proposed that the roller is designed as a swivel roller, in particular the fork is rotatably mounted about at least one pivot axis relative to the bearing element, wherein the pivot axis preferably runs parallel to the first direction and / or is identical to the first axis of rotation.

[0026] In the aforementioned embodiment of the roller, it is preferred that the roller has a caster and / or the pivot axis runs perpendicular to the roll axis and / or the pivot axis runs skew to the roll axis.

[0027] A roller according to the invention can also be characterized in that the fork and / or the rolling axis can be forced into at least one predetermined position relative to the bearing element and / or the support structure with respect to the pivot axis by means of at least one first return device.

[0028] Furthermore, it is preferred that the roll axis runs substantially parallel to the main plane of the support structure.

[0029] Finally, it is proposed for the roller arrangement that it comprises at least one support plate and / or at least one, preferably a plurality of fixed roller(s) and / or steering roller(s) (69'''), in particular connected to the support plate and / or fastened to the support plate.

[0030] The invention is therefore based on the surprising finding that the driving stability of a container with rollers arranged at respective interfaces, in particular corner blocks and / or corner fittings, can be increased by at least reducing the play of a locking block in a (rotational) position in which the locking block is positively connected to the interface by displacing the locking block in a direction along a direction of rotation of the locking block.

[0031] In particular, the use of an actuating / handling element connected to the locking block allows for attachment without additional tools. The connection can optionally be permanently and / or non-destructively detachable.

[0032] Furthermore, the operation of the locking block in the manner described below enables the bearing element to be locked to the supporting structure of the container, in particular the corner block on the underside, which increases accessibility for a user.

[0033] The invention also allows for the gradual reduction of play, in particular not only in discrete, digital steps. This can be achieved by using a threaded connection in the second actuating element. This further offers the advantage that the relationship between the movement of the second actuating element or the second handling element, on the one hand, and a movement, in particular a longitudinal movement, of the locking block, on the other hand, can be adjusted, adapted, or changed via the pitch of the thread. A detachable connection of a second handling element to the remaining components of the second actuating element can also be provided.This makes it possible to first determine an initial position of the second actuating element by rotating the threaded connection in order to ensure the best possible use of a travel path of the second handling element after (re)connection with the second actuating element.

[0034] Finally, the integration of the clearance compensation into the bearing element allows for the reduction of clearance while the roller is still attached to the container. In particular, the clearance can be easily readjusted with the roller still attached, as there is no need to disassemble the roller and, in particular, no additional tools are required.

[0035] Further features and advantages of the invention will become apparent from the following description, in which preferred embodiments are explained with reference to the accompanying figures.

[0037] Fig. 1 shows a bearing element 1 according to the invention. The bearing element 1 comprises a base element 3. The base element 3 has a raised portion 5. A locking block 7 is arranged above the raised portion 5. The locking block 7 is rotatable relative to the base element 3 and the raised portion 5 by means of a first actuating element about a first axis of rotation 9, which extends along a first direction. The locking block 7 can be rotated by a user using the first actuating element without tools and even while the bearing element or a roller is attached to a container by means of the bearing element 1. The first actuating element comprises a first handling element in the form of a lever 11.

[0038] In Fig. 1, the locking block 7 is shown in a first rotational position. As explained below, this first rotational position allows the locking block 7, preferably together with at least part of the elevation 5, to be inserted into an opening of a supporting structure, such as a corner fitting of a container. In this case, the locking block 7 is in particular guided completely through the opening, with the elevation 5 preferably being arranged partially in the opening. Preferably, a surface of the base element 3 then rests against a surface of the supporting structure, in particular the corner fitting.

[0039] By actuating the first actuating element by means of the first handling element 11, the locking block 7 can be moved into the Fig. 2. As explained below, this creates a positive connection between the bearing element 1 and the supporting structure or corner fitting.

[0040] However, tolerances in the thickness of the supporting structure or the corner fitting in the area of ​​the opening, or wear in the area of ​​the opening, may result in play between the locking block 7 and the supporting structure or the corner fitting. In particular, the surface of the locking block 7 facing the elevation 5 or the base element 3 may not be resting on the supporting structure or the corner fitting.

[0041] To reduce this play, a second actuating element is provided with a second handling element in the form of a second lever 13. As explained below, a movement of the second lever 13 from the position shown in the Fig. 2 shown (rotational) position into the position shown in the Fig. 3, the (rotational) position shown is a movement of the locking block 7 in a second direction 15 which runs parallel to the first axis of rotation 9.

[0042] The functioning of the bearing element 1, in particular of the first and second actuating element, is explained below using the Fig. 4a to 4e explained.

[0043] The Fig. 4a shows a top view of the bearing element 1 from direction A in Fig. 3. The Fig. 4a shows a first actuating element 17, omitting the first handling element in the form of the lever 11. The actuating element 17 comprises a receptacle 19 for the lever 11, which is in particular formed integrally with the locking block 7.

[0044] Furthermore, the locking block 7 comprises an external thread area 21 which, as explained later, forms part of the second actuating element.

[0045] In Fig. 4b shows the lever 11 in conjunction with the receptacle 19. The receptacle 19 and the lever 11, in particular a periphery of the receptacle 19 and a cutout in the lever 11, have a complementary shape such that the locking block 7 is securely connected to the lever 11 in a rotationally engaging manner.

[0046] In Fig. 4c shows that the second actuating element 23 comprises a threaded disk 25. The threaded disk 25 comprises a cutout with an internal thread complementary to the external thread region 21. By rotating the threaded disk 25 relative to the locking block 7, the position of the locking block 7 relative to the base element 3 can be changed along the second direction 15. Furthermore, in Fig. 4c shows that the first lever 11 is locked by means of a locking element 16 in the position shown in the Fig. 3 and 4b to 4e, which corresponds to the first rotational position of the locking block. The locking element 16 comprises, in particular, a ball catch.

[0047] In order to enable rotation of the threaded disc 25 independently of the first actuating element 17, in particular the first lever 11, connecting elements in the form of pins 27 are provided.

[0048] If the second handling element in the form of the second lever 13, as in Fig. 4d, the pins 27 engage in recesses 29 of the lever 13. Thus, the lever 13 is securely coupled to the threaded disk 25. Furthermore, rotation of the lever 13 and the threaded disk 25 of the second actuating element is possible independently of a movement of the first lever 11 or the first actuating element 17, and thus independently of a rotation of the locking block 7 about the first rotation axis 9.

[0049] By rotating the lever 13, the threaded disc 25 is moved or rotated relative to the locking block 7 and its external threaded portion 21. The pitch of the internal thread of the threaded disc 25 or the external threaded portion 21 converts a rotational movement of the lever 13 into a longitudinal movement or lifting movement of the locking block 7 in the direction 15. The ratio of the movement of the lever 13 and the movement along the direction 15 can be adjusted via the pitch of the thread of the threaded disc 25 or the external threaded portion 21.

[0050] In Fig. Figure 4e shows the bearing element 1 with a roller fastening element 31 connected to it. The fastening element 31 can be a fastening plate of a roller or a roller assembly.

[0051] Although a rotation of the locking block 7 about the first axis of rotation 9 with the aid of a first actuating element 17 or first handling element or lever 11 has been described above, in which the movement of the first actuating element 17 or first handling element or lever 11 takes place in the form of a rotation about the axis of rotation 9, the invention is not limited to this. The movement of the first actuating element 17 or first handling element or lever 11 can also take place by movements other than a rotation and / or the rotation can take place about other axes, in particular also those that run perpendicular to the axis of rotation. This can be made possible, for example, by corresponding gear devices that convert a movement of the first actuating element 17 or first handling element or lever 11 into a movement of the locking block 7. A movement of the second actuating element 23 orsecond handling element or lever 13 is not limited to a rotational movement about the rotation axis 9. This can also include other movements, in particular using gear devices.

[0052] In the Fig. 5a to 9b show a second embodiment of a bearing element 1' according to the invention in combination with a supporting structure of a container in the form of a corner fitting 33' with an opening 35', in particular designed according to ISO 1161. Those elements of the bearing element 1' that correspond to those of the bearing element 1 bear the same reference numerals, but are simply primed. Fig. 5a to 9b show the connection of the bearing element 1' to the corner fitting 33'.

[0053] The Fig. 5a to 5d show the bearing element 1' after insertion of the locking block 7' through the opening 35' into the corner fitting 33'. As shown in particular Fig. As can be seen from Figure 5d, the elevation 5' is partially arranged in the opening 35'. Due to the circumferential shape of the elevation 5', which is complementary to the inner contour of the opening 35', there is a positive fit between the opening 35' of the corner fitting 33' and the elevation 5' and thus of the base element 3'. This positive fit prevents rotation of the base element 3' and thus of the bearing element 1' about the first rotation axis 9'.

[0054] After the locking block 7' has been inserted into the corner fitting 33' through the opening 35', a surface 37' of the corner fitting 33' of the base element 3', in particular arranged on the underside, rests at least partially on a surface 37' of the base element 3'.

[0055] In the Fig. 5a to 5d, the locking block 7' is shown in a first rotational position about the rotational axis 9'. In this position, the bearing element 1' is not locked to the corner fitting. If the corner fitting 33' were lifted, the locking block 7' and thus the bearing element 1' would fall out of the corner fitting 33' due to gravity, since the locking block 7' can easily exit the corner fitting 33' through the opening 35'.

[0056] In the Fig. 6a to 6d show the situation in which the locking block 7' was moved into a second rotational position by moving the lever 11'. As can be seen in particular Fig. As can be seen from Figure 6b, a positive connection is formed between the locking block 7' and the corner fitting 33'. This prevents the locking block 7' from being pulled out of the corner fitting 33' or from falling out. The positive connection between the elevation 5' and the opening 35' thus means that rotation of the bearing element 1', in particular of the base element 3', relative to the corner fitting 33' is not possible. However, due to the overlap of the surface 43' on the underside of the locking block 7' and the surface 45' on the inside of the corner fitting 33', in particular in the area of ​​the opening 35', there is a positive connection between the locking block 7' and the corner fitting 33'.

[0057] However, as in Fig. As shown in Figure 6d, there is a clearance 41' between the surfaces 43' and 45' between the locking block 7' and the corner fitting 33'. This clearance 41' means that a movement, albeit slight, of the bearing element 1' relative to the corner fitting 33' remains possible. When the bearing element 1' is connected to a roller, this leads to the possibility of unwanted movement, in particular tilting of the roller, which can have a negative impact on tracking and / or negative impact on the control and steerability, in particular of a swivel roller, and / or can lead to increased loads, even to an overload of the roller, in particular of a (swivel) roller with caster. It can also cause the opening 35' and the corner fitting 33' to deflect, which can further increase the clearance 41'.

[0058] In the bearing element 1', it is therefore provided that a rotation of the lever 13' by means of the second actuating element 23' enables a movement of the locking block 7' relative to the base element 3' in the second direction 15'. Due to the engagement of the external thread region 21' with the internal thread of the threaded disk 25', a rotation of the lever 13' and thus a rotation of the threaded disk 25' leads to a movement of the locking block 7' in the second direction 15'. The movement occurs counter to a force built up by means of at least one prestressing element in the form of at least one compression spring 42'. The prestressing element 42' ensures that the locking block 7', after passing through the opening 35', is located within the corner fitting 33' such that the surface 43' is above the surface 45'. This then enables unhindered rotation of the locking block 7' by means of the first actuating element 17' orof the lever 11', in particular from the one shown in the . Fig. 5a to 5d shown position in the Fig. 6a to 6d. As previously mentioned, the threaded disc 25' is securely connected to the second lever 13' by means of the pins 27' and the recesses 29'.

[0059] In the Fig. 7a to 7d, the bearing element 1' is shown in the position after such a movement of the lever 13'. As in Fig. As can be seen in Figure 7d, surfaces 43' and 45' lie on top of each other, meaning that the locking block 7' is in contact with its surface 43' and the surface 45' of the corner fitting 33'. The clearance 41' has thus been eliminated and is no longer present. This results in a play-free attachment of the bearing element 1' and the corner fitting 33'.

[0060] In the Fig. 8a and Fig. 8b shows further views of the bearing element 1' in the (rotational) position of the levers 11' and 13', which corresponds to the second rotational position of the locking block 7', in which, however, the play 41' is still present. The fastening element 31' is not shown. Furthermore, Fig. 8a to 9b show a second locking element 22' in the form of a ball catch. This second locking element 22' enables the second lever 13' and thus the second actuating element 23' to be locked in a position in which the play 41' is removed.

[0061] In the Fig. 9a and Fig. 9b shows the situation in which the clearance 41' is released by moving the lever 13' from the position Fig. 6a to 6d or 8a and 8b shown (rotational) position, in the Fig. The (rotational) position shown in Figures 7a to 7d has been eliminated.

[0062] Like the Fig. 1 to 9b, the range of movement of the second actuating element 23, 23' or the second handling element or lever 13, 13' can be limited. To ensure that the entire play 41' can be compensated, it is provided that the lever 13, 13' can be detachably connected to the remaining part of the second actuating element 23, 23'. Thus, first, a position of the locking block 7, 7' in the direction 15, 15' can be set, which leads to a predetermined play 41'. In this case, the lever 13, 13' can be in a position which differs from that as shown, for example, in the Fig. 2, Fig. 6a, Fig. 6c and Fig. 6d or 8a and Fig. 8b. In order to ensure a maximum adjustment path of the lever 13, 13', in order to compensate for a maximum play 41', a connection of the lever 13, 13' with the second actuating element 23, 23', in particular the threaded disc 25, 25' and / or the pin 27, 27' is released and in the Fig. 2, Fig. 6a, Fig. 6c and Fig. 6d or 8a and Fig. 8b. Such an adjustment can be made before or during a connection of the bearing element 1, 1' to the corner fitting 33', and also before, during, or after a rotation of the locking block 7, 7' from the first to the second position. The connection can also be released such that the lever 13, 13' remains captively connected to the second actuating element 23, 23', and only a connection to the pin 27, 27' is released, and after rotation of the lever 23, 23', the pin 27, 27' is arranged in another recess 29, 29'.

[0063] In the Fig. 10a to 10c show a roller 47' in the form of a heavy-duty double swivel caster connected to the corner fitting 33' by means of the bearing element 1' from various perspectives. The roller 47' comprises a fork 49' connected to the bearing element 1' by means of the fastening element 31'. The fork 49' is pivotally mounted about a pivot axis 51'. Wheels 53' are rotatably mounted in the fork 49' about a rolling axis 55'. Since the rolling axis 55' is arranged skewed relative to the pivot axis 51', the roller 47' has a caster.

[0064] In the Fig. Finally, Figures 11a to 11c show various views of a roller 47" connected to the corner fitting 33' via the bearing element 1'. In contrast to the roller 47', the roller 47" is a heavy-duty swivel castor with a wheel 53". The other elements of the roller 47" that correspond to those of the roller 47' bear the same reference numerals, but with double primes.

[0065] Finally, in Fig. 12 the bearing element 1' is shown in connection with a floor roller arrangement 61'''. The fastening element 31' is connected to a support plate 65''' by means of spacers 63'''. Two fixed rollers 67''' and two swivel rollers 69''' are fastened to the support plate 65'''.
