Description

[0001] The present invention relates to a device for holding and securing cargo, in particular in the form of a locking bar, wherein an inner tube is arranged axially displaceable in an outer tube and can be locked via a locking device. State of the art

[0002] Many different systems already exist for securing cargo, particularly in the box-shaped body of a truck. The closest prior art to the present application is DE 202 18 023 U1 of the applicant. This describes a beam-like profile in which an inner or adjusting tube can be axially displaced incrementally within a base tube in a device designed as a clamping beam. Pins are located at both ends of the profile, which are inserted into corresponding recesses provided in the cargo space or on transport containers. To fix the device, the adjusting tube is pulled out to extend it until the pins abut between the surfaces, preferably in the recess, and the device is clamped.

[0003] A disadvantage is that this device cannot be adapted to all possible lengths. Furthermore, during transport, slight changes occur in the distance at which the clamping bar was originally inserted, either due to vibrations or twisting of the container or the sideboard beams relative to each other. These slight changes result in a loose fit of the device. This leads to a reduced clamping effect and thus a safety risk, and the movement of the device in or against the corresponding clamping recesses causes noises such as rattling or knocking.

[0004] For example, DE 43 35 478 C2 discloses a locking bar locking device. The locking bar comprises an upper and a lower tube. A rack profile is formed on the outside of the lower tube of the locking bar. The rack is part of a locking mechanism. A disadvantage of this is that the locking mechanism is exposed to the surface and is very susceptible to damage or contamination.

[0005] Furthermore, DE 17 81 124 A discloses a device for supporting and securing cargo.

[0006] Furthermore, WO 98 / 56 614 A1 discloses a load securing system for refrigerated vehicles.

[0007] Furthermore, US 43 32 515 A discloses a device for securing cargo.

[0008] Furthermore, DE 71 26 630 U discloses a barrier bar for securing cargo.

[0009] Furthermore, DE 39 01 412 A1 discloses an axially clampable locking bar for securing cargo.

[0010] Furthermore, DE 43 35 478 C2 discloses a locking bar safety device. Object of the invention

[0011] The object of the present invention is to create a continuously adjustable device for securing and holding cargo, which also independently compensates for minor changes in the distance of the cargo space. Solution to the task

[0012] The problem is solved by a device according to the characterizing part of claim 1. In at least one end of the rod, at least one pin is seated which is supported against a force storage element.

[0013] This inventive arrangement of the pin allows the device to be inserted at any distance that does not exceed its maximum length. The user roughly pre-adjusts the required length by pulling the inner tube out of the outer tube or by pushing the inner tube into the outer tube. The desired length is locked in place by a locking mechanism that engages with locking recesses in the inner tube. The invention also includes a rail with locking recesses, which can be mounted on or embedded in the inner tube.

[0014] To secure the load, the device according to the invention, with a pin protruding from one end, is inserted into or placed on a designated recess or raised area in the cargo space. The device is then adjusted to the required approximate length. For this purpose, the two tubes are telescopically moved relative to each other. To move the tubes, the user releases the locking mechanism by operating a lever. The tubes can now be pulled or pushed to the desired length. Once the desired length is reached, the user increases the pressure so that the pin retracts against the force of the energy storage element. The user then releases the lever, the locking mechanism engages with the next locking recess, and the locking bar is secured at the required length.

[0015] Since the required lengths are not standard dimensions, it may happen that a length between two detent positions is actually needed. The pin located at the upper end of the rod is supported against a force storage element and is guided in such a way that it is movable in the axial direction by a certain distance. If the rod is set to a length that is actually too short, the force storage element pushes the pin out of its guide element accordingly. Thus, the device according to the invention can be continuously adjusted to any desired length within the maximum length of the rod.

[0016] In addition to adapting to intermediate lengths located between the individual locking recesses, the inventive connection of the pin via a force storage element offers the advantage that changes in the clamping distance, which may occur briefly during clamping, e.g., due to vibrations of the vehicle or twisting of the container or cargo space, are compensated for. This ensures that the device always sits firmly between the corresponding mating elements. There are no rattling noises from loose parts.

[0017] The locking bar according to the invention can be used in both vertical and horizontal positions. It also allows for arrangement at a certain angle. Character description

[0018] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; this shows in Fig. 1 a longitudinal section through a locking bar according to the invention; Fig. 2 an enlarged section shown from a central area of ​​the locking bar accordingly Fig. 1; Fig. 3 another enlarged section shown from an upper area of ​​the locking bar accordingly Fig. 1; Fig. 4 another enlarged section shown from a lower area of ​​the locking bar accordingly Fig. 1;

[0019] Fig. Figure 1 shows a locking bar 1 according to the invention. This bar consists of an inner tube 2 and an outer tube 3. The inner tube 2 and the outer tube 3 share a common central axis 4. A groove 16 is formed in the inner tube 2. A locking rail 5 with locking recesses 24 is located in this groove. The invention also includes the possibility of forming the locking recesses 24 directly into the inner tube 2. A sliding element 9 is attached to the lower end of the inner tube 2. Noses 29 are formed onto this sliding element. The noses act like leaf springs and are slightly pre-tensioned. This prevents movement of the inner tube 2 in the radial direction within the outer tube 3 and thus also prevents the generation of rattling noises.

[0020] The locking recesses 24 engage a locking device 6 according to Fig. 2 together. The locking device 6 consists of a housing sleeve 12, which is mounted on the outer tube 3. Inside the housing sleeve 12 is a locking pawl 25. When connected, this engages in a locking recess in the outer tube 3.

[0021] A lever 11 is rotatably arranged about a pivot axis 13 in the housing sleeve 12. A locking lug 15 is formed on the lever 11, the lever 11 being supported against a power storage element 14 in the area of ​​the locking lug 15.

[0022] The lever 11 extends beyond the upper end of the outer tube 3 with the end on which the locking lug 15 is located. This allows the lever 11 with the locking lug 15 to engage in a locking recess 24 of the locking rail 5 in the inner tube 2.

[0023] According to Fig. 3. An attachment 10 is placed on the open inner tube 2, with a connecting pin 22 engaging in the inner tube 2 and a pipe section 21 overlapping the inner tube 2. A sleeve 20 with a cylindrical chamber 26 is located in the pipe section 21, in which a power storage element 19 and partially a pin 18 are accommodated. The sleeve 20 is preferably made in two parts. The pin 18 has a flange 27 at its end, which is located in the cylindrical chamber 26. This flange abuts an annular shoulder 17 in the cylindrical chamber 26.

[0024] The spring-loaded pin 18 protrudes from the attachment 10 and is conically shaped in its upper region. It also has a transverse slot 23 in this region.

[0025] Accordingly Fig. 4 at the lower end of the outer tube 3 is a base pin 8, which is inserted into the outer tube 3 via an insert element 7.

[0026] The functioning of the present invention is as follows: For holding and securing cargo, preferably in the cargo space of a truck or in a container, the locking bar 1 according to the invention is fixed and clamped in or on designated devices with its lower base pin 8 and upper pin 18. These devices can be recesses or projections, for example, in or on rails, or directly in the walls, floor, or ceiling of the cargo space, or even in transport containers or rails mounted thereon. The conical shape is particularly suitable for insertion into recesses of a so-called airline track. A transverse slot 23 and a further transverse slot 28 in the base pin 8 allow attachment to a rod rail.

[0027] The locking bar 1 is adjusted to the required length via the locking device 6 after the lower base pin 8 has been inserted into, for example, the corresponding recess. To do this, the user presses the lever 11 of the locking device 6. This causes the lever 11 to rotate around the pivot axis 13 and move its locking lug 15 out of the locking recess 24 in the locking rail 5 on the inner tube 2. The user can then extend the inner tube 2 further out of the outer tube 3 to lengthen the locking bar. The sliding element 9 at the lower end of the inner tube 2 assists this process.

[0028] When the pin 18 reaches its designated locking device, the user increases the extension force, causing the pin 18 to retract against the force of the energy storage element 19 into the attachment 10 or the cylinder chamber 26. The user then releases the lever 11. This causes the energy storage element 14 to rotate the lever 11 again around the axis of rotation 13, and the locking lug 15 is pressed into a corresponding locking recess 24 in the locking rail 5 in the inner tube 2. The locking rod 1 according to the invention is thus locked at the desired length.

[0029] Since the required lengths of the locking device are not standardized distances, lengths may be needed that lie between two detent positions or detent recesses 24. This stepless adjustment to the length is achieved via the spring-loaded pin 18. Due to the guidance of the pin 18 in the cylinder chamber 26, in which the energy storage element 19 is also inserted, it is movable in the axial direction until its flange 27 reaches the stop against the annular shoulder 17.

[0030] Furthermore, the axially movable connection of the pin 18 to the inner tube 2, on the one hand, and the locking mechanism, on the other, make it possible to automatically compensate for changes in the clamping distance that occur in the short term, e.g., during travel, due to vibrations or twisting of the cargo space. If the distance in the cargo space increases, the pin 18 is simply pushed further out of the cylinder chamber 26 by the energy storage element 19. This has the advantage that a secure fit of the locking rod 1 is always guaranteed. This also prevents the generation of noises such as rattling or the like.
