Description

[0001] The present invention relates to a method for operating a load securing device for securing cargo on the floor of a cargo space of a vehicle according to the preamble of claim 1 and a load securing device for securing cargo on the floor of a cargo space of a vehicle according to the preamble of claim 5.

[0002] Cargo, the goods being transported, is carried on the floor of a vehicle's cargo space. The vehicle is, for example, a truck or a freight car. The area of ​​the cargo space is a multiple of the length or width of a Euro pallet. A Euro pallet is 120 cm long and 80 cm wide. For logistical reasons, when loading the cargo space, it may happen that not the entire surface is covered with Euro pallets. Due to the vehicle's acceleration during transport, the cargo would then shift into these gaps. Therefore, it is already known to use load securing devices, such as securing bars or straps, to prevent the cargo from shifting into the areas without Euro pallets.However, such securing bars or loads are complex to install and generally require loading lugs on the vehicle's side walls. Due to the small surface area of ​​the loading straps or securing bars, there is a risk of damage to the cargo itself, as the securing forces are applied primarily along a line or at a single point.

[0003] To secure cargo, a stack of, for example, 7 to 8 Euro pallets can also be used. However, this number of approximately 7 to 8 Euro pallets results in an additional weight of approximately 140 kg, and these Euro pallets also require corresponding storage space in the cargo area at all times.

[0004] US 10,556,720 B2 shows a foldable pallet for storing cargo on two levels.

[0005] US 4,147,112 reveals a cargo support with a horizontal part and a vertical part.

[0006] WO 02 / 02421 A1 shows a pallet with a base supporting the load as the base part and a side wall protruding from the base as a securing part.

[0007] The object of the present invention is therefore to provide a method for operating a load securing device for securing cargo on the floor of a cargo space of a vehicle and a load securing device for securing cargo on the floor of a cargo space of a vehicle in which the cargo can be reliably secured with a simple change from a transport configuration to a load securing configuration of the load securing device and vice versa.

[0008] This problem is solved by a method for operating a load securing device for securing cargo on the floor of a vehicle's cargo space, comprising the steps of: placing the load securing device on the floor of a vehicle's cargo space, increasing the vertical extent as the height of the load securing device from a transport configuration of the load securing device to a load securing configuration of the load securing device by performing a relative movement of a securing part of the load securing device to a floor part of the load securing device, wherein the relative movement is essentially performed as a translational movement between the floor part and the securing part of the load securing device.Essentially a translational movement preferably means that the proportion of translational movement in the movement, particularly at all points of the base and / or the securing part, is greater than 80%, 90%, or 95%. This allows the load securing device to be set up particularly easily and quickly, i.e., converted from the transport configuration to the load securing configuration.

[0009] In a supplementary embodiment, the relative movements of several securing parts are essentially carried out as the translational movement between the base part and the securing parts of the load securing device, so that the horizontal edges of the securing parts act as a stop for the load to secure cargo on the floor of the cargo space.

[0010] In another variant, the base part and the at least one securing part, in particular all securing parts, are aligned essentially parallel to each other in the transport configuration and / or the load securing configuration and / or during the enlargement and / or reduction of the vertical extension as the height of the load securing device, in particular with a deviation of less than 30°, 20°, 10°, 5° or 2°.

[0011] In an additional embodiment, the, preferably plate-shaped, base part and the at least one, preferably plate-shaped, securing part, in particular all securing parts, are aligned in the transport configuration and / or the load securing configuration and / or during the enlargement and / or reduction of the vertical extension as the height of the load securing device essentially, in particular with a deviation of less than 30°, 20°, 10°, 5° or 2°, parallel to the floor of the vehicle's cargo space.

[0012] A load securing device according to the invention for securing cargo on the floor of a vehicle's cargo space, comprising a base part for placing on the floor of the vehicle's cargo space, a securing element for securing cargo on the floor of the vehicle's cargo space, a mechanism for increasing the vertical extent as the height of the load securing device from a transport configuration to a load securing configuration and conversely for decreasing the vertical extent as the height of the load securing device from a load securing configuration to a transport configuration by enabling a relative movement of a securing element of the load securing device to a base part of the load securing device, wherein the relative movement can be carried out with the mechanism essentially as a translational movement between the base part and the at least one securing element of the load securing device.

[0013] Preferably, the load securing device comprises several securing elements, in particular at least two, three or five securing elements.

[0014] In a further embodiment, the base part and the at least one securing part, in particular all securing parts, are designed as a plate and / or grid and / or disc-shaped and / or rectangular and / or cuboid-shaped in a section.

[0015] In a supplementary variant, the kinematics of the mechanism are designed such that the base part and the at least one securing part, in particular all securing parts, are aligned essentially parallel to each other in the transport configuration and / or the load securing configuration and / or in an intermediate configuration between the transport configuration and the load securing configuration, in particular with a deviation of less than 30°, 20°, 10°, 5° or 2°.

[0016] In an additional embodiment, the mechanism for the kinematics of the relative movement between each safety part and each base part or each safety part comprises several levers.

[0017] Advantageously, each lever is pivotably mounted at a first end region by a hinge on a locking element or a base section about a pivot axis, and is mounted at a second end region by a slotted bearing so as to be translationally movable on a locking element or a base section. Preferably, the first and second end regions of each lever are opposite end regions of each lever. Preferably, the length of each end region of each lever is less than 30%, 20%, 10%, or 5% of the total length of each lever.

[0018] In a further embodiment, the pivot axis of each hinge is essentially, in particular with a deviation of less than 30°, 20°, 10°, 5° or 2°, parallel to a fictitious plane spanned by each locking part or each bottom part.

[0019] In a supplementary variant, the translational direction of movement of each lever at the bearing as the slot is essentially, in particular with a deviation of less than 30°, 20°, 10°, 5° or 2°, parallel to a fictitious plane spanned by each locking part or each bottom part and / or one or two levers are mounted in each slot and these one or two levers are pivotably mounted to each other about an additional pivot axis with an additional connecting joint, preferably on each locking part.

[0020] Preferably, the mechanism between each locking part or each bottom part and each locking part comprises four levers.

[0021] In a supplementary variant, two levers are connected to each other by a connecting joint, so that the mechanism comprises a locking part or a base part and a locking part with four levers and two connecting joints.

[0022] In particular, the two levers, each connected to the other by a connecting joint, are arranged at each end area in the area of ​​a longitudinal side edge or a broad side edge of each locking part or of each bottom part and each locking part.

[0023] Preferably, the increase in the vertical extension as the height of the load securing device from a transport configuration of the load securing device to a load securing configuration of the load securing device is carried out before and / or during and / or after the load securing device is placed on the floor of the vehicle's cargo space.

[0024] In another variant, the base part and / or the at least one safety part, in particular all safety ropes, essentially has a length of 120 cm and / or a width of 80 cm, especially with a deviation of less than 10%, 5%, 3% or 2%.

[0025] In another variant, the base part and / or the at least one safety part, in particular all safety ropes, have essentially the same length and / or width, especially with a deviation of less than 10%, 5%, 3% or 2%.

[0026] In a further embodiment, the method described in this patent application is carried out with a load securing device described in this patent application.

[0027] In a supplementary variant, the method described in this patent application can be carried out using the load securing device described in this patent application.

[0028] In another embodiment, a lever is mounted in each slot and this lever is pivotably mounted about an additional pivot axis with an additional connecting joint, preferably on each bottom part.

[0029] In an additional embodiment, the length and / or width of the base part and / or locking part is variable, preferably between 0% and 30%, particularly between 0% and 10%, by means of a length mechanism and / or a width mechanism, for example, in that the at least one longitudinal side edge and / or the at least one broad side edge is formed by each longitudinal side bar and / or each broad side bar, and each longitudinal side bar and / or each broad side bar is movable with an edge mechanism, particularly as a spindle drive, relative to the remaining base part and / or each locking part, preferably substantially by means of a translational movement, so that preferably during the movement, in particular translational movement,the opposite longitudinal edges of each base part and / or each securing part and / or each securing part are aligned substantially parallel to each other, in particular with a deviation of less than 30°, 10°, 5° or 2°.

[0030] Preferably, the length mechanism allows the length of each base part and / or each safety part to be changed.

[0031] Preferably, the width mechanism allows the width of each base part and / or each securing part to be changed.

[0032] In another variant, the load securing device includes a protective cover for placing over the rest of the load securing device, particularly in a load securing configuration. Advantageously, this prevents objects from slipping into the space or spaces between the base part and the at least one securing element, because the protective cover acts as a stop for the load.

[0033] In a supplementary embodiment, in the method for operating the load securing device for securing cargo on the floor of a vehicle's cargo space, after increasing the vertical extent as the height of the load securing device from a transport configuration of the load securing device to a load securing configuration of the load securing device, a protective cover, in particular a protective cover described in this patent application, is placed over the load securing device, so that preferably at least 70%, 90% or 99% of the vertical extent of the load securing device is covered by the protective cover.

[0034] The protective cover is conveniently designed in a sack shape with a downward-facing opening for slipping over the load securing device.

[0035] In another embodiment, the protective cover is made of a material and / or a film, in particular flexible and / or deformable.

[0036] In particular, the height of the protective cover shall be at least 70% or 90% of the height of the load securing device in the transport configuration.

[0037] In particular, the length of the protective cover shall be at least 95%, 99%, 100% or 105% of the length of the load securing device in the transport configuration.

[0038] The width of the protective cover should be at least 95%, 99%, 100% or 105% of the width of the load securing device in the transport configuration.

[0039] In a supplementary embodiment, the protective cover is essentially cuboid in shape, without taking the opening into account.

[0040] In an additional variant, the thickness of the base part and / or the at least one securing part is between 0.2 cm and 4 cm, in particular between 0.5 cm and 2 cm.

[0041] Preferably, the height of the load securing device in the transport configuration is essentially, in particular with a deviation of less than 30%, 20% or 10%, the sum of the thickness of the base part and the thickness of the securing part or the sum of the thicknesses of the securing parts.

[0042] Preferably, the height of the load securing device in the transport configuration is essentially constant, in particular with a deviation of less than 30%, 20% or 10%.

[0043] In a supplementary embodiment, the thickness of the base part and / or the at least one securing part is essentially constant, in particular with a deviation of less than 30%, 20% or 10%.

[0046] In the Fig. Figures 1 to 10 depict a load securing device 1 for securing cargo on the floor of a vehicle's cargo space in a first embodiment. The vehicle, its floor, and the storage space are not shown in the figures. The load securing device 1 comprises a base section 2 and a total of four securing elements 3. The base section 2 and the securing elements 3 are designed as plates, essentially in the shape of a cuboid with a very low height. The base section 2 and the securing elements 2 have four edges 4 at their horizontal ends: two longitudinal edges 5 and two transverse edges 6. The base section 2 and the securing elements 2 have identical length 7 and identical width 8. The length 7 is 120 cm and the width is 80 cm, i.e., the length and width of a Euro pallet. The load securing device 1 is in Fig. 1 in a load protection configuration, in Fig. 3 in a transport configuration and in Fig. 2 is shown in an intermediate configuration between the transport configuration and the load securing configuration. The load securing device 1 has in the Fig. In the transport configuration shown in Figure 3, a height 9 of 5 cm is achieved, i.e., the sum of the individual heights of the base section 2 and the four securing parts 3, each of 1 cm. The base section 2 and the securing parts 3 each span a fictitious plane 11.

[0047] A mechanism 10 enables a relative movement between the base part 2 and the locking parts 3 as a translational movement. During this translational movement, the base part 2 and the locking part 3, i.e., the fictitious planes 11 spanned by the base part 3 and the locking parts 3, are always essentially parallel to each other, in particular with a deviation of less than 30°, 20°, 10°, 5°, or 2°. A lever 12 has a first end region 13 and a second end region 14 in the axial direction. A first end region 13 of a first lever 12 is pivotally attached to the base part 2 by a hinge 16 about a pivot axis 17. Fig. 6) The pivot axis 17 is essentially parallel to the fictitious plane 11 and essentially parallel to the longitudinal side edge 5, particularly with a deviation of less than 30°, 20°, 10°, 5°, or 2°. A second lever 12 is mounted at a second end region 14 on a bearing 18, which is a slot 18 in the slot, by means of a translational movement in one direction essentially parallel to the fictitious plane and essentially parallel to the broad side edge 6. Additionally, this end region 14 of this second lever 12 is pivotable about an additional pivot axis 36 in the bearing 18, which is the slot 18, by means of an additional connecting joint 19. The additional pivot axis 36 is essentially parallel to the fictitious plane 11 and essentially parallel to the longitudinal side edge 5 of the base part 2. The additional connecting joint 19 is designed simply as a cylindrical stud that is mounted in the slot 18 ( Fig. 7). The first lever 12 is located at a second end region 14 opposite the first end region 13 with the in Fig. 6 described and illustrated hinge 16 at the bearing 18 as the slot 18 ( Fig. 8) mounted on the locking element 3 with a translational movement with a direction of movement 20 and additionally this second end region 14 of the first lever 12 is pivotably mounted with a further lever 12 on a second end region 14 of this further lever 12 with the additional connecting joint 19 about the additional pivot axis 36. In the Fig. In the bearing 18 shown as the slot 18, two levers 12 are thus pivotably mounted at their respective second end regions 14 with the additional connecting joint 19 about the additional pivot axis 36 and are additionally movably mounted in the bearing 18 as the slot 18 in the direction of movement 20 as the translational movement. The levers 12 are thus pivotally mounted at their opposite end regions 13, 14 with a hinge 16 to a base part 2 or a locking part 3 and at the bearing 18 as the slot 18. At the locking parts 3, two levers 12 are pivotally mounted at their end regions 14 with the additional connecting joint 19 relative to each other.

[0048] Additionally, the two levers 12 are pivotally connected to each other by a connecting joint 15 at each broad side edge 6 between a base part 2 and a locking part 2 or between two locking parts 3. As shown in Fig. Thus, the levers 12 at the left end regions of the broad side edges 6 of the base part 2 and the securing parts 3 are pivotally connected to the base part 2 or the securing part 3 by the hinge 16. According to the illustration in Fig. Thus, a lever 12 is attached and supported at the right end of the broad side edge 6 of the base part 2, with the bearing 18 forming the slot 18 and with the additional hinge 19, in a pivotal and translational manner to the base part 2. As shown in Fig. Thus, two levers 12 are pivotally and translationally connected and mounted on the right end region of the broad edge 6 of the locking element 2, with the bearing 18 forming the slot 18 and with the additional hinge 19, to the locking element 3. This configuration of the levers 12 on each broad edge 6 of the base part 2 and the locking elements 3 is identical on the opposite broad edge 6 of the base part 2 and the locking elements 3. The mechanism 10 thus causes a kinematic relative movement between the base part 2 and the locking elements 3, such that the base part 3 and the locking elements 3 are always essentially parallel to each other and have essentially the same distance from each other. Fig. Figure 1 shows the load securing device 1 in the transport configuration with the maximum possible height 9 of approximately 180 cm, and in the transport configuration the additional connecting joint 19 are located in the slots 18 in a position with a maximum distance to the longitudinal side edge 5 as a stop in the slot 18. In the Fig. In the transport configuration of the load securing device 1 shown in Figure 3, the additional connecting joints 19 are located at an opposite position in the direction of movement 20 with respect to the Fig. 7, so that the distance of the additional connecting joint 19 is minimal to the right front longitudinal side edge 5 as shown in the illustration in Fig. 3 as a further stop in the slot 18.

[0049] The change in height 9 of the load securing device 1 and the relative movement as the translational movement between the base part 3 and the securing part 3 during the change from the transport configuration to the load securing configuration and vice versa is carried out with a movement mechanism 21 ( Fig. 1, Fig. 9 and Fig. 10). The movement mechanism 21 comprises a threaded spindle 27 with a spindle nut 28 and a threaded rod 29. In the middle locking part 3, as the third locking part 3 from the top, there is a recess 22 ( Fig. 9) formed and in this recess 22, the movement mechanism 21 is essentially arranged as the threaded spindle 27 with the spindle nut 28 and the threaded rod 29. The threaded rod 29 is pivotably mounted about a pivot or rotation axis essentially parallel to the locking element 3 and can be manually set into rotation by means of a rotary disk 32. This rotation of the threaded rod 29 causes a translational movement of the spindle nut 28 in the direction of the rotation axis of the threaded rod 29. Two primary lifting arms 23 and two secondary lifting arms 24 are pivotably mounted about a lifting arm pivot axis 31 on the spindle nut 28 by means of a lifting arm connecting joint 30. The primary and secondary lifting arms 23, 24 are thus fixedly connected to the spindle nut 28 and are only pivotably mounted about the lifting arm pivot axis 31.The primary lifting arms 23 are pivotably connected to the spindle nut 28 at a first end region, and a second end region opposite the first end region of the primary lifting arms 23 is pivotably mounted and / or attached to the second locking element 3 from above at a recess 22 identical to the third locking element 3 from above about a lever pivot axis 26 by corresponding joints. The secondary lifting arms 24 are pivotably connected to the spindle nut 28 at a first end region, and a second end region opposite the first end region of the secondary lifting arms 24 is pivotably mounted and / or attached to the fourth locking element 3 from above at a recess 22 identical to the third locking element 3 from above about a lever pivot axis 26 by corresponding joints.The recesses 22 on the second, third and fourth locking part 3 from the top are identical in terms of location and position.

[0050] In the Fig. In the transport configuration of the load securing device 1 shown in Figure 3, the three recesses 22 in the three securing parts 3 are thus aligned. The rotary disk 32 allows a translational movement of the spindle nut 28 in the direction of the axis of rotation of the threaded rod 29, so that in the load securing configuration according to Fig. 1 the spindle nut 28 is positioned at the end of the recess 22 with a maximum distance to the front longitudinal side edge 5 according to Fig. 1 exhibits. In the Fig. In the transport configuration of the load securing device 1 shown in Figure 3, the spindle nut 28 has the minimum distance to the longitudinal side edge 5 of the securing part 3, and the primary and secondary lever arms 23, 24 are arranged in the aligned recesses 22 together with the threaded spindle 27. Due to the transmission ratio of the movement mechanism 21 of the threaded spindle 27, a height 9 once reached is maintained against gravity, so that the load securing device 1 can be easily and reliably removed from the transport configuration as shown in Figure 3. Fig. 3 with the small height 9 of 5 cm into the load securing configuration with the height 9 of approximately 180 cm can simply be moved by actuating the rotary disc 23 by means of the translational movement between the base part 2 and the securing parts 3 and vice versa.

[0051] To secure cargo on the floor of a vehicle's cargo space (not shown), the load securing device 1, arranged in the transport configuration, is placed on the corresponding unloaded portion of the cargo space floor. The height 9 of the load securing device 1 is then increased using the turntable 32 until the cargo is secured against slippage. Alternatively, the height 9 of the load securing device 1 can be sufficiently increased before being placed on the cargo space floor. The floor section 2 also functions as a securing element 3 for securing cargo in the area of ​​the vehicle's cargo space floor.

[0052] In Fig. 11 and Fig. Figure 12 shows a second embodiment of the load securing device 1. The following discussion focuses primarily on the differences compared to the first embodiment. Fig. 1 to 10 are described. The movement mechanism 21 is designed simply as a lifting arm 33 and a rope 34. The lifting arm 33 is connected at one end to a bearing 18, which is a slot 18, on the base part 2 in a direction of movement 20 in the plane of the drawing. Fig. 11 and Fig. The first end of the lifting arm 33, which is pivotably mounted on the base part 2 with the slot 18 and pivotably mounted with the additional connecting joint 19, is connected to a cable 34. By applying a tensile force to the cable 34, the first end of the lifting arm 33 is moved towards the right longitudinal edge 5 as shown in the illustration. Fig.The lifting arm 33 moves within the slot 18, thereby increasing the height 9 of the load securing device 1. As soon as no tensile force is applied to the cable 34, the load securing device 1 automatically returns to its transport configuration due to gravity. Therefore, in this second embodiment of the load securing device 1, a locking device for the cable 34 or only the first end of the lifting arm 33 is optionally provided on the base 2.

[0053] Overall, the inventive method for operating the load securing device 1 and the inventive load securing device 1 offer significant advantages. The mechanism 10 has a kinematic design such that the base part 2 and the securing elements 3 are moved in a translational motion, parallel to each other, between the transport configuration and the load securing configuration at a substantially identical distance in a direction perpendicular to the imaginary planes 11. The load securing device 1 enables effective securing of cargo because all edges 4 of the base part 2 and the securing elements 3 are available for securing the cargo against slippage over a large area. The number of securing elements 3 of the load securing device 1 can therefore be further adapted to the needs of the cargo in different configurations of the load securing device 1.Optionally, the base part 2 and / or the securing part 3 are designed such that the length 7 and / or the width 8 of the base part 2 and / or the securing part 3 can be changed for additional adaptation to loading gaps on the floor of the vehicle's cargo space.
