Description

[0001] The invention relates to a lid locking device for a transport container and a transport container which has the lid locking device.

[0002] Lid locking devices are known for easy loading and unloading of transport containers. These devices hold the lid of a transport container in an open position during loading and unloading. This prevents the lid from closing unintentionally, which in turn increases safety during loading and unloading. Furthermore, it prevents injuries to people and / or damage to the transported goods.

[0003] From EP 2 230 189 A1, a lid locking device for a transport container is known, which is movable between a locking position and a transport position. For this purpose, the lid locking device has two half-shells connected by a hinge and a bracket element. The bracket element has a closed contour in which two bracket legs are connected to each other via two bracket webs. A flexible locking spring is provided between the hinge and one of the two half-shells. When the lid of the transport container is opened, a bracket web of the bracket element is pressed under the locking spring until, in the locking position, the bracket web, and thus the bracket element, is locked by the force of the locking spring. This keeps the lid in an open position and makes closing the lid more difficult.

[0004] The lid locking devices known from the prior art are complex to manufacture. Furthermore, it has been shown that the known lid locking devices only exhibit low holding forces.

[0005] The invention is therefore based on the objective of providing a lid locking device for a transport container and a transport container that have reduced complexity, while simultaneously providing reliable locking and improved holding force, which is also adjustable.

[0006] The object of the invention is achieved by the features of the characterizing part of claim 1, namely in that at least the locking element causes at least a temporary elastic deformation of the pivot bracket when the lid locking device is moved between the locking position and the transport position. By using the pivot bracket as an elastic component, no further components are required to ensure reliable locking of the lid locking device. In addition, the complexity of the lid locking device is reduced. The assembly time of the lid locking device is also reduced. Furthermore, fewer components need to be adjusted relative to each other, so that the overall manufacturing time of the lid locking device according to the invention is reduced. Since only the locking element and the pivot bracket interact with each other, the risk of wear and thus the susceptibility to wear is simultaneously reduced.

[0007] Advantageously, the locking element causes the pivoting bracket to undergo elastic deformation, at least when the lid locking device is in the locked position. Alternatively, the pivoting bracket experiences temporary elastic deformation only during movement, or at least during a portion of the movement, between the locked and transport positions, and essentially retains its original shape in both the locked and transport positions. Overall, it is possible to release the locking mechanism of the pivoting bracket, and thus the lid, easily, requiring only minimal force. It is also designed so that the elastic deformation is present both during movement and in the locked position.

[0008] In accordance with the present invention, elastic deformation occurs when the pivot bracket, during intended use, exists both in a deformed state and—at another time—in an undeformed state. Furthermore, it is advantageous if the undeformed state of the pivot bracket remains essentially identical even after numerous elastic deformations. In particular, the deformation is reversible. Elastic deformation is temporary or temporal when, during movement from the transport position to the locking position and / or during movement from the locking position to the transport position, both the elastic deformation is generated and subsequently released.

[0009] The movement between the locking position and the transport position is either the movement from the locking position to the transport position or from the transport position to the locking position or a combination of the two.

[0010] Regardless of the precise design of the bearing unit and the guide unit, the swivel bracket is mounted in the bearing unit. It is advantageous for the bearing unit to have at least one bearing element. In particular, it is advantageous if the swivel bracket is pivotally mounted in the bearing element, for example, in a bearing.

[0011] It is advantageous if the swivel bracket has at least two swivel bracket legs, particularly if the swivel bracket legs are connected to each other by at least one swivel bracket base. A corner is preferably arranged between a swivel bracket leg and a swivel bracket base. For example, the swivel bracket has a substantially rectangular or a substantially trapezoidal shape. Preferably, the swivel bracket has a tapered shape, particularly a shape that tapers towards the locking element. For example, it is possible for the two swivel bracket legs to converge, preferably in the direction of the locking element. Furthermore, it is advantageous if the profile of all swivel bracket legs is substantially the same and / or constant.Particularly when the pivot bracket has a substantially circular cross-section, it is advantageous if the diameter of all pivot bracket legs is substantially the same, preferably constant. If the pivot bracket has two pivot bracket legs, it is advantageous if the locking element is symmetrical about a central axis of the lid locking device, the central axis preferably extending in a longitudinal direction. This enables synchronous movement of the pivot bracket legs.

[0012] Alternatively, it is specifically provided that the swivel bracket is essentially designed as a pin or as a hook.

[0013] To avoid unwanted noise, such as rattling or clattering of the pivot bracket, it is preferred that the pivot bracket be mounted in the bearing unit with essentially no play. In the context of the present invention, "without play" means that movement in the direction of an outer contour is at least partially prevented. For this purpose, it is particularly recommended that the distance between the pivot bracket and the bearing unit be substantially less than 0.1 mm, preferably substantially less than 0.05 mm. Additionally or alternatively, it is preferred that the pivot bracket be arranged, and preferably secured, to the guide unit by means of a spacer. It is further preferred that the spacer be arranged in a recess of the guide unit.Furthermore, it is advantageously provided that the spacer surrounds the swivel bracket at least partially, and preferably completely, at least in one section. It is also advantageous if the spacer is made of a plastic material, preferably at least partially made of plastic.

[0014] The transport container is, for example, a flight case and / or is suitable for transporting fragile goods, such as musical instruments, measuring instruments, or sound equipment. The transport container has at least one lid and at least one body.

[0015] The lid locking device is advantageously attachable to the transport container, in particular such that the bearing unit can be attached to the transport container lid and the guide unit to the transport container body. A reversed attachment is also possible, so that the bearing unit can be attached to the transport container body and the guide unit to the transport container lid. The bearing unit and the guide units are separate units that are movable relative to each other, in particular pivotable, at least between the transport position and the locking position. The bearing unit and the guide unit are particularly movable relative to each other such that they enclose an angle in the locking position, for example, an angle of approximately 120° to 60°, preferably substantially 70°, substantially 80°, substantially 90°, or substantially 100°.

[0016] In a standard design, the guide unit and the bearing unit have essentially the same dimensions, particularly the same transverse extent. Specifically, the transverse direction extends essentially parallel to a pivot axis, with the pivot bracket being pivotable about this axis. A longitudinal direction extends perpendicular to the transverse direction. Material can be saved if the bearing unit has a shorter longitudinal extent than the guide unit. Of course, it is also possible for the guide unit to have a shorter longitudinal extent than the bearing unit. Furthermore, the absolute transverse and longitudinal extent of the lid locking device can be determined based on the dimensions of the transport container and / or the weight of at least the container lid.Furthermore, the transverse and longitudinal extensions of the lid locking device depend on the force required to lock and hold the lid of the transport container.

[0017] The transport position corresponds to the position of the lid locking device when the transport container is closed, preferably when the lid is fully in place on the container body. The locking position corresponds to the position the lid locking device assumes when the transport container is open for loading and unloading, preferably when fully open. Furthermore, in the locking position, the transport container lid is held or locked in an open position, thus facilitating the loading and / or unloading of the transport container.

[0018] According to an advantageous embodiment of the lid locking device, the bearing unit and the guide unit are arranged at an angle to each other in the locking position. Advantageously, the pivot bracket connects the bearing unit and the guide unit. Furthermore, it is advantageous if the pivot bracket, in the locking position, forms a first angle with the bearing unit and a second angle with the guide unit. In particular, the second angle is smaller than the first angle.

[0019] In the transport position, the bearing unit and the guide unit lie essentially in the same plane. When the lid of the transport unit with the attached lid locking device is opened, the unit attached to the lid—the guide unit or, preferably, the bearing unit—moves with the lid. During this movement, the pivoting bracket pivots relative to the bearing unit. Simultaneously, the pivoting bracket moves relative to the guide unit, with the locking element elastically deforming the pivoting bracket, at least temporarily. Specifically, the pivoting bracket moves along the locking element. In doing so, the locking element presses the pivoting bracket into a deformed shape. This at least temporary elastic deformation of the pivoting bracket causes it to move into a position where it interacts with the locking element to hold the lid locking device in the locked position.

[0020] Advantageously, the swivel bracket is partially elastically deformed in the locking position, particularly compared to the transport position. In this case, the deformation of the swivel bracket also exists in the locking position. Alternatively or additionally, the swivel bracket experiences elastic deformation only or also during movement between the locking position and the transport position. In other words, in this case, the swivel bracket exhibits the same deformation in both the locking and transport positions; in particular, the swivel bracket has an initial shape, for example, an undeformed shape, in both the transport and locking positions.

[0021] When the transport container is closed again, the pivoting bracket undergoes a pivoting movement relative to the bearing unit. In particular, the elastic deformation of the pivoting bracket is released by the locking element, and preferably the pivoting bracket is returned to essentially the same shape as before the movement from the transport position to the locking position. The movement of the pivoting bracket ends at the latest when the lid locking device reaches the transport position. Specifically, the pivoting bracket moves back along the locking element into the transport position. Preferably, the transport container is closed by moving, and in particular pulling, the lid towards the body of the transport container.

[0022] In the event that the hinge is in its initial shape in both the transport position and the locking position, it is specifically provided that, during the movement from the locking position to the transport position, the hinge is elastically deformed by the detent element and then returned to its initial shape, for example by reversing the elastic deformation.

[0023] It is also provided that the swivel bracket is elastically deformed in the transport position and deforms elastically during the movement from the transport position to the locking position by returning to its undeformed starting position.

[0024] Furthermore, it may be provided that the guide unit and / or the storage unit has / have at least one recess. In particular, it may be provided that the swivel bracket is arranged in the recess in the transport position and / or that the locking element is at least partially arranged in the recess. This reduces the required installation space.

[0025] In particular, it is intended that the locking element and the hinge lever interact with each other at least partially in a force-fit manner in the locking position.

[0026] In an advantageous embodiment of the invention, the locking element and the pivot bracket interact in a force-fit manner in the locking position. The force-fit between the pivot bracket and the locking element holds the pivot bracket in its position and thus indirectly keeps the transport container lid open. It is therefore possible to dispense with additional components, thereby further minimizing the complexity of the lid locking device.

[0027] To facilitate the movement of the pivoting bracket, in a preferred embodiment of the lid locking device, the locking element has at least one guide contour. When the lid locking device moves between the locking position and the transport position, the guide contour causes an elastic deformation of the pivoting bracket. In particular, the locking element has a guide contour arranged laterally on the locking element in a top view. If the pivoting bracket has at least one pivoting bracket leg, the guide contour, especially the guide contour arranged laterally on the locking element, causes an elastic deformation of at least one pivoting bracket leg of the pivoting bracket.

[0028] Furthermore, it is preferably provided that the locking element has at least two guide contours. It is more preferred that the two guide contours are each arranged on one side of the locking element, and even more preferably that the two guide contours are arranged axially symmetrically to a central axis of the locking element, for example in a top view.

[0029] When the lid locking device moves from the transport position to the locking position, the pivot arm undergoes elastic deformation due to the guide contour. In other words, the guide contour generates the deformation of the pivot arm, specifically the elastic deformation. For example, the elastic deformation of the pivot arm is such that at least one pivot arm, viewed from above, undergoes a lateral deformation, for example, outwards towards an edge of the guide unit. If two pivot arms are provided, the locking element preferably pushes the two pivot arms apart.

[0030] It should be noted that in the top view, when the lid locking device is in the transport position, the lid locking device can be seen in one plane.

[0031] It is particularly intended that the locking element has a substantially rectangular shape in plan view. Preferably, the guide contour, for example in plan view, projects at least partially from the substantially rectangular shape. Preferably, a guide contour extends from opposite sides of the locking element. Preferably, the guide contours are arranged opposite each other or offset from each other. Alternatively, it is preferably intended that the guide contour is formed as a recess, for example in plan view, in the substantially rectangular shape.

[0032] To further stabilize the pivot bracket and thus improve the hold of the lid locking device in the locked position, it is preferred that the guide contour has at least one indentation, and that the pivot bracket is at least partially received in the indentation in the locked position. In particular, the pivot bracket leg is at least partially received in the indentation in the locked position. To reduce complexity, it is further preferred that the pivot bracket, and in particular the pivot bracket leg, is only at least partially received in the indentation in the locked position.

[0033] If the shape of the indentation is a negative of the outer contour of the pivot arm in the locking position, the interaction between the pivot arm and the locking element in the locking position of the lid locking device can be further improved. The shape of the indentation can be viewed, for example, from a top view. If, for instance, the pivot arm, and in particular the pivot arm, has a circular profile in cross-section, the indentation will have a circular segment shape, at least in a top view. For example, the indentation may have a semicircular shape. Furthermore, the pivot arm has an inclined profile in the side view when the lid locking device is in the locking position. It is therefore advantageous if the shape of the indentation extends obliquely in the side view.In other words, it is advantageous if the shape of the indentation extends obliquely through a plane parallel to the top view. Preferably, the indentation extends along an edge of the locking element. It should be noted here that the profile of the swivel bracket preferably has a constant cross-section along its length.

[0034] Unintentional movement of the pivoting bracket from the locking position can be prevented if the recess has at least one support projection, and if the support projection extends into an edge region of the recess. In one embodiment, the support projection is designed such that a force required to move the lid locking device from the locking position to the transport position is greater than a force required to move the

[0035] The lid locking device moves from the transport position to the locking position. In the locking position of the lid locking device, the pivot bracket, and in particular the pivot bracket leg, rests at least partially against the support projection; in particular, the pivot bracket engages with the support projection. To facilitate the insertion of the pivot bracket into the recess, it is preferred that the support projection has a rounded outer edge.

[0036] To further simplify the entry of the pivoting lever into the guide contour, particularly into the recess, the guide contour is provided with at least one insertion section. It is particularly advantageous if the insertion section is at least partially curved. Alternatively or additionally, the insertion section is provided to be at least partially designed as an insertion ramp. The insertion section allows the pivoting lever to slide along it, at least during movement of the lid locking device from the transport position to the locking position. This prevents collisions between the pivoting lever and the locking element, particularly the guide contour, and / or damage to the pivoting lever and / or the guide contour. It is further preferred that the pivoting lever moves at least partially along the insertion section during movement between the locking position and the transport position.In particular, it is provided that the insertion section at least partially prepares and / or induces an elastic deformation of the pivot bracket. Advantageously, the guide projection is arranged adjacent to the insertion section. In particular, the guide projection rests at least partially against the pivot bracket in the locking position. It goes without saying that it is also possible for the guide projection to rest completely against the guide projection in the locking position.

[0037] When the lid locking device moves from the transport position to the locking position, the pivot bracket, in particular one leg of the pivot bracket, moves along the guide contour, preferably undergoing at least partial elastic deformation. Simultaneously, the pivot bracket changes its position relative to the guide unit and pivots about its bearing in the bearing unit. During this movement, the pivot bracket straightens itself.

[0038] Provided the support projection is present, the pivot bracket passes over the guide projection after moving along the insertion section. The guide projection at least partially guides the movement of the pivot bracket during movement of the lid locking device from the transport position to the locking position. It is possible that the elastic deformation of the pivot bracket remains essentially constant or is at least partially canceled at and / or after passing over the guide projection.

[0039] In particular, the guide unit is provided to have an edge. Furthermore, it is advantageous if the pivot bracket, in the locking position, is positioned at least partially between the edge of the guide unit and the detent element, especially the guide contour, so that the pivot bracket deforms elastically at least partially towards the edge of the guide unit during movement between the locking position and the transport position. This allows the pivot bracket to be pushed at least partially away from the detent element, at least when the lid locking device is moved from the transport position to the locking position. It is possible to provide that the pivot bracket deforms elastically at least partially towards the edge of the guide unit. This makes it possible to reduce the installation space required for the lid locking device.If two swivel bracket legs are provided, it is advantageous that the two swivel bracket legs are deformed away from each other during elastic deformation, for example, pushed apart.

[0040] Alternatively or additionally, the locking element, in particular the guide contour, may protrude at least partially from a lateral edge of the guide unit, and the locking element may be directed towards a pivot bracket, such that the pivot bracket deforms elastically away from the lateral edge of the guide unit during movement between the locking position and the transport position. It is particularly intended that the pivot bracket deforms elastically at least partially towards an interior space of the guide unit. If two pivot bracket legs are provided, it is advantageous if the two pivot bracket legs are deformed towards each other, for example, pressed together.

[0041] To simplify the assembly of the lid locking device, a lid locking device can be provided in which the guide unit has at least one collar and the locking element is arranged on the collar. In particular, the collar can have a collar recess and the locking element can be arranged on the collar. This reduces or completely prevents the locking element from slipping within the guide unit. Preferably, the locking element is arranged in a form-fitting manner within the collar recess. The provision of a collar simplifies the attachment of the lid locking device to the transport container. For this purpose, the lid locking device can have at least one fastening element on the collar. For example, the fastening element is a hole designed to receive a screw or a rivet.

[0042] According to a preferred embodiment, the guide unit comprises at least one guide element, and the locking element is designed as a separate component from the guide element. In particular, the locking element is connected to the guide element. For example, the connection is designed such that the locking element is detachably connected or riveted to the guide element. Detachably connected in this context means that the two components, here the locking element and the guide element, can be separated without damage. This facilitates the replacement of the locking element, for example, due to wear. Preferably, the lid locking device is designed such that the locking element comprises at least one locking element base unit and at least one locking unit.For example, the locking element base unit may be made of a different material than the locking unit. The locking element base unit may be made of metal and / or coated with a material, particularly zinc-plated. The locking unit is preferably manufactured using a non-corrosive material, such as a plastic, and / or at least partially coated with plastic. According to an exemplary embodiment, the locking element base unit is at least partially overmolded with the locking unit. Therefore, an injection molding process, such as a plastic injection molding process, is preferably used to manufacture the locking element. In particular, the guide contour is provided to be made of or coated with a plastic.Alternatively or additionally, it is provided that the swivel bracket is coated with plastic, at least in the areas where it interacts with the locking element.

[0043] Preferably, in the locking position, the pivoting bracket engages with the locking unit. This causes the pivoting bracket to lock into place, thus securing the pivoting bracket. The lid locking device is then in the locking position. More generally, the pivoting bracket holds the lid locking device in the locking position. Specifically, the pivoting bracket is locked by one leg engaging with the locking unit.

[0044] Alternatively, it is proposed that the locking element be formed integrally with the guide element. The locking element is thus part of the guide element. This reduces assembly effort.

[0045] The assembly effort can be further reduced if the swivel bracket is manufactured in one piece, preferably with rounded corners. Regardless of the shape of the swivel bracket, it is possible for it to be made of metal and / or coated with a material, particularly galvanized. In particular, it is intended that the swivel bracket be manufactured as a bent component.

[0046] It is further preferably proposed that the swivel bracket has at least one opening. In particular, it is provided that the opening is formed on a swivel bracket base which is arranged on the guide unit. Advantageously, it is provided that the opening is arranged between the guide element and the locking element. This reduces the manufacturing effort of the swivel bracket.

[0047] Preferably, the locking element is arranged within the opening of the swivel bracket base. The swivel bracket base has, in particular, two opposing end faces. The end faces are preferably moved away from each other, at least temporarily, by the locking element. Preferably, the end faces are the same distance apart in the initial position and in the locking position. For example, during movement from the initial position to the locking position, each end face interacts with a guide projection to elastically deform the swivel bracket. The two guide projections, for example, push the end faces away from each other. In the locking position, the end faces interact with the guide projections, for example, by means of a positive locking mechanism, in particular to lock the swivel bracket.Because the locking element is located inside the opening of the swivel bracket base, the swivel bracket is widened through the opening during movement between the locking position and the transport position, and the swivel bracket undergoes elastic deformation.

[0048] To ensure that the lid locking device not only holds the lid of the transport container in the locking position but also facilitates opening and closing the container, it is specifically proposed that the lid locking device further comprise at least one hinge. It is also proposed that the hinge be arranged laterally adjacent to the bearing unit and the guide unit. Additionally or alternatively, to reduce the required installation space, it is proposed that the hinge be arranged between the bearing unit and the guide unit.

[0049] In particular, it is provided that the locking element is arranged at least partially between the guide unit and the hinge. Alternatively, it is also provided that the locking element is arranged at least partially between the bearing unit and the hinge. Because the hinge is located above the locking element in plan view, the hinge protects the locking element from environmental influences.

[0050] According to a further aspect of the invention, a transport container is provided. The transport container comprises at least one transport container body, at least one transport container lid, and at least one lid locking device according to the invention. The lid locking device connects the transport container body and the transport container lid. The embodiments and advantages of the lid locking device according to the invention described above apply equally to the transport container according to the invention and vice versa. In particular, the bearing unit is attached to the transport container lid, and the guide unit is attached to the transport container body.

[0051] For an even distribution of force and load, it is advantageous if the transport container has at least two lid locking devices, in particular if the lid locking devices are arranged equally on one side of the transport container lid and on a side of the transport container body adjacent to the transport container lid.

[0052] Further advantageous embodiments of the invention will become apparent from the following description of the figures and the dependent subclaims. They show:

[0054] In the various figures of the drawing, identical parts are always labelled with the same reference symbols.

[0055] The following description claims that the invention is not limited to the exemplary embodiments and not to all or several features of the described combinations of features; rather, each individual partial feature of the exemplary embodiment(s) is also significant for the subject matter of the invention, independent of all other partial features described in connection therewith, both on its own and in combination with any features of another exemplary embodiment.

[0056] In Figure 1 A transport container according to the invention is shown, which is generally designated by reference numeral 1. The transport container 1 has a transport container body 2 and a transport container lid 3. The transport container body 2 and the transport container lid 3 are connected to each other via two lid locking devices 4.

[0057] The lid locking devices 4 each have a bearing unit 5 and a guide unit 6. The respective bearing unit 5 is attached to the transport container lid 3 and the guide unit 6 is attached to the transport container body 2, in particular by screws or rivets. The lid locking devices 4 are positioned between a Figure 3a depicted transport position and one in Figure 3b The depicted locking position is movable.

[0058] As in Figure 2 As shown, each lid locking device 4 has a pivot bracket 7 in addition to the bearing unit 5 and the guide unit 6. The pivot bracket 7 is mounted in a bearing element 5a of the bearing unit 5, namely in a bearing 8. In the present embodiment, the bearing 8 is designed as a separate component and is connected to the bearing element 5a of the bearing unit 5 by means of rivets 9.

[0059] The guide unit 6 has a guide element 6a and a locking element 10. In the locking position, the locking element 10 interacts with the pivot bracket 7 such that the lid locking device 4 is held in the locking position (see Figure 3b ). For this purpose, the locking element 10 causes at least a temporary deformation of the pivot bracket 7 when the lid locking device 4 is moved between the locking position and the transport position. In particular, the locking element 10 and the pivot bracket 7 interact in a force-fit manner in the locking position, so that the lid locking device 4 can be released from the locking position by a force exerted on the bearing unit 5 that exceeds a predetermined threshold value.

[0060] The swivel bracket 7 has two swivel bracket legs 7a and at least one swivel bracket base 7b. The swivel bracket legs 7a are connected to each other via the swivel bracket base 7b.

[0061] The locking element 10 has a guide contour 11 on each side. In a top view, the guide contours 11 are arranged opposite each other and laterally on the locking element 10, as shown in the Figure 3a As shown. When the lid locking device 4 is moved between the locking position and the transport position, the pivot bracket 7 moves along the guide contours 11, or the pivot bracket legs 7a move along the guide contours 11. In the present embodiment, the pivot bracket legs 7a move essentially synchronously along their respective guide contours 11.

[0062] The locking element 10 is essentially axially symmetrical about a central axis M of the lid locking device 4, the central axis M extending through both the bearing unit 5 and the guide unit 6. The central axis M divides the lid locking device 4 into two symmetrical halves. The lid locking device 4, and in particular the locking element 10 and the guide contour 11, are described below essentially for one axially symmetrical half. It is understood that the description applies equally to the other half of the lid locking device 4.

[0063] When the lid locking device 4 is moved from the transport position to the locking position, the pivot bracket 7 with its pivot bracket legs 7a is positioned so that an angle α ( Fig. 3bThe angle α is formed between the guide element 6a and the pivot bracket 7a, more precisely between a plane in which the guide element 6a essentially extends and a longitudinal axis 7d of the pivot bracket leg 7a. The angle α reaches its maximum value in the locking position. When the lid locking device 4 is moved from the locking position to the transport position, the angle α is reduced again until it reaches its minimum value, preferably 0°, in the transport position.

[0064] When the lid locking device 4 moves from the transport position to the locking position, the pivot arm 7a moves along the detent element 10. The pivot arm 7a is guided by the guide contour 11. The guide contour 11 causes an elastic deformation of the pivot arm 7a. In the present embodiment, the guide contour 11 pushes the pivot arm 7a outwards towards an edge 6b of the guide unit 6.

[0065] Furthermore, the guide contour 11 has an indentation 12. As in Figure 3bAs shown, in the locking position, each pivot arm 7a is partially received in a recess 12. The recess 12 has a shape that is a negative form of an outer contour 7a1 of the pivot arm 7a. The pivot arm 7, and thus also the pivot arm 7a, has a circular cross-section. Therefore, the recess 12 has a shape that is essentially a circular segment when viewed from above. As shown in the Figure 3a As shown, the indentation 12 extends in a side view S at an angle corresponding to the angle α in the locking position. Thus, in the locking position, the pivot arm 7a engages with the indentation 12 in a force-fit manner.

[0066] The guide contour 11 has an insertion section 14. The insertion section 14 is partially curved. When the lid locking device 4 moves between the transport position and the locking position, the pivot bracket 7, specifically the pivot bracket leg 7a, moves at least partially along the insertion section 14. The curved shape of the insertion section 14 facilitates movement into the recess 12, and the pivot bracket leg 7a is successively deformed. The two pivot bracket legs 7a experience maximum elastic deformation at a vertex 13 of the insertion section 14.

[0067] Due to the shape of the insertion section 14, the pivot arm 7a reaches its maximum deformation during movement from the transport position to the locking position, shortly before the pivot arm 7a reaches the indentation 12. When the lid locking device 4 is in the locking position, the pivot arm 7 is elastically deformed in the present embodiment, but with a lower degree of deformation than in the case of maximum deformation.

[0068] In the locking position, the swivel bracket 7 is at least partially arranged between the edge 6b of the guide unit 6 and the locking element 10. As shown in Figure 3bAs shown, the pivot arm 7a is arranged in the locking position between the edge 6b of the guide unit and the guide contour 11. Thus, the pivot arm 7, namely the pivot arm 7a, deforms elastically at least partially in the direction of the edge 6b of the guide unit 6 when moving from the transport position to the locking position.

[0069] Alternatively or additionally, the locking element 10 can have at least one section that protrudes from a lateral edge 6c of the guide unit 6, wherein the locking element 10 at least in this section points towards the pivot bracket 7, so that the pivot bracket 7 deforms elastically away from the lateral edge 6c of the guide unit 6 during a movement between the locking position and the transport position.

[0070] Furthermore, the guide unit 6 has a collar 6d, wherein the locking element 10 is arranged on the collar 6d, namely in a collar recess 6e. Although it is generally possible for the locking element 10 and the guide element 6a to be formed in one piece, in the present embodiment the locking element 10 and the guide element 6a are formed as separate components. The locking element 10 is connected to the guide element 6a by rivets 15 (in Figure 2 connected via three rivets 15, only one rivet 15 being marked with a reference symbol for illustrative purposes). To attach the lid locking device 4 to the transport container 1, the collar can be attached via holes 6f (in Figure 2 only one hole (6f) marked with a reference mark.

[0071] Furthermore, the locking element 10 comprises a locking element base unit 10a and a locking unit 10b. In the present embodiment, the locking element base unit 10a and the locking unit 10b are formed in one piece. However, the locking element base unit 10a and the locking unit 10b can also be formed as separate components, with the preferred configuration being that at least the locking unit 10b is made of plastic.

[0072] The locking unit 10b engages with the pivoting bracket 7, in particular with the pivoting bracket leg 7a, when the lid locking device 4 is in the locking position.

[0073] In the present embodiment, the pivot bracket 7 is formed in one piece, with each pivot bracket leg 7a having two corners 7c and being connected to the pivot bracket base 7b on one side, which is arranged facing the bearing 8. The corners 7c have a rounded shape. Furthermore, according to the illustrated embodiment, the pivot bracket 7 has a tapered shape, with the two pivot bracket legs 7a approaching each other from the bearing element 5a towards the guide element 6a. The pivot bracket 7 is essentially trapezoidal.

[0074] During movement from the transport position to the locking position, the pivot arms 7a are moved away from each other by the guide contours 11, so that the opening 16 enlarges, at least temporarily. When the pivot arms engage in the recesses 16, the arms 7a move at least partially back towards each other.

[0075] Furthermore, the swivel bracket 7 has an opening 16. Since the opening 16 is arranged between the guide element 6a and the locking element 10, and is therefore part of the swivel bracket base 7b, which is arranged on the guide unit 6, the swivel bracket base 7b and thus the opening 16 are in Figure 2 represented solely by a dashed line.

[0076] As from Figure 1 As can be seen, the lid locking device 4 also has hinges 17, here two. These hinges 17 are arranged adjacent to the bearing unit 5 and the guide unit 6. In particular, each hinge 17 has two hinge halves 17a, with one hinge half 17a being adjacent to the bearing unit 5 and the other hinge half 17a being adjacent to the guide unit 6.

[0077] The Figures 4a and 4bshow a lid locking device 4 according to a second embodiment. Just like the lid locking device 4 according to the Figures 2 , 3a and 3b The lid locking device 4 also features according to the Figures 4a and 4b a storage unit 5 and a control unit 6. Regarding the design of the storage unit 5 and the control unit 6, reference is made to the description of the Figures 2 , 3a and 3b referred.

[0078] Furthermore, the lid locking device 4 has, according to the Figures 4a and 4b a swivel bracket 7. The swivel bracket 7 is pivotally mounted in the bearing unit 5 so that the lid locking device 4 can be moved between a transport position (see Figure 4a ) and a locking position (see Figure 4b ) is movable.

[0079] Even those in the Figures 4a and 4b The illustrated lid locking device 4 has a hinge 17 with two hinge halves 17a. As shown Figures 4aAs can be seen, the hinge halves 17a can have different extensions in a longitudinal direction L.

[0080] The hinge 17 is partially arranged between the bearing unit 5 and the guide unit 6. The pivot bracket 7 is partially arranged between the hinge 17 and the bearing unit 5 and partially between the hinge 17 and the guide unit 6. A bearing element 5a, shown only as an indication, is arranged between the bearing unit 5 and one hinge half 17a. Furthermore, the hinge 17 is arranged such that the locking element 10 (not shown) is at least partially located between the guide unit 6 and the hinge 17, in particular between one hinge half 17a. The hinge 17 covers the locking element 10, thus protecting it from environmental influences.

[0081] For attachment to a transport container 1, the lid locking device 4 also has, according to the second, in the Figures 4a and 4bThe illustrated embodiment features a collar 6d with holes 6f (here only one hole 6f is labelled). Furthermore, the hinge 17 also has several hinge holes 17b. When the hinge 17 is correctly mounted on the bearing unit 5 and the guide unit 6, a hinge hole 17b is aligned with a hole 6f, so that a fastening element (not shown), for example a rivet or screw, secures the hinge 17 and the bearing unit 5, or the guide unit 6, together to a transport container.

[0082] The locking element 10 of the exemplary embodiment of the Figures 4a and 4b For example, according to the following, with regard to the Figures 5a to 5c The described embodiment of a locking element 10 is designed. It is also specifically provided that the locking element is designed according to the Figures 1 to 3b is trained.

[0083] Another embodiment of a lid locking device 4 is shown in detailed views in the Figures 5a to 5c shown. In this embodiment, the locking element 10 is arranged in an opening 16 of a pivot bracket 7 (see Figures 5a to 5c ). The locking element 10 is arranged between two opposing end faces of the swivel bracket base 7b or between two swivel bracket base end sections 7f.

[0084] Starting from the transport position, as described in Figure 5aAs shown, a pivot bracket 7, namely at least one (here two) pivot bracket base end section 7f of a pivot bracket base 7b of the pivot bracket 7, moves along a guide contour 11 of the locking element 10. In doing so, the pivot bracket 7, in particular at least one (here two) pivot bracket leg 7a, undergoes an elastic deformation away from the guide contour 11. The movement of the pivot bracket 7 is facilitated by an insertion section 14. At a vertex 13 of the insertion section 14, the pivot bracket legs 7a undergo a maximum deformation (see figure). Figure 5b ). The swivel bracket legs 7a are elastically deformed in the direction of an edge 6b of the guide unit 6.

[0085] After passing the vertex 13, the swivel stirrup legs 7a move towards each other again, so that the elastic deformation is at least partially reversed (see Figure 5c). The swivel bracket base end sections 7f lie against the locking element 10 in the locking position and interact at least partially with the locking element 10 or its guide contours 11 in a force-fit manner to lock the swivel bracket 7.

[0086] The locking element 10 according to the Figures 5a to 5c The illustrated embodiment has an axially symmetrical structure with respect to a locking element center axis R (see Figure 5b ).

[0087] Furthermore, the locking element 10, according to the embodiment of the Figures 5a to 5c Connecting means 18, here two (see Figure 5b ), for example, screws or rivets. The locking element 10 and the guide unit 6 can be connected using the connecting means 18. In this embodiment, it is also specifically provided that the locking element 10, as in the Figures 4a and 4b , is covered by a hinge 17.
