Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a load securing device for a transport vehicle with at least one locking device which is formed in the form of a rail, comprising a first rail and a second rail and arranged in the loading surface of the transport vehicle and at least one securing means which is a retaining element anchored in the arresting device, the retaining element comprising at least one locking cam for securing the securing means against transverse displacement and inclined in the locked position, and at least one securing cam for securing the securing means against automatically releasing and loosing in the non-locked position.

BACKGROUND OF THE INVENTION

Such devices are known in principle and are used to secure the load on the loading surfaces of transport vehicles from the stresses incurred in transport, for example, to prevent the transverse movement of goods stored on rail freight wagons.

In rail transport, the transported goods are subject to different stresses. In this connection, reference should be made to the transport rules 'Bánd 1, Anlage II zum RIV-úberinkommen', published in 'Deutschen Eisenbahn-Gutertarif Teil I', Ableitung A, concerning the securing of freight costs. The cost securing measures must guarantee the reliability of the operation and prevent damage to goods and freight wagons.

DE-GM 876 25 690 and US-PS 27 43 684 disclose load securing devices against sliding on the loading area of a commercial vehicle, in which perforated rails with anchored retaining blocks are arranged on the loading area in addition to the load securing measures laid down in the traffic regulations. . A disadvantage of these devices is that, according to this known standard art, securing the goods in the transverse direction is insufficient.

Furthermore, DE-C-198 24 678 discloses a device for securing loads against transverse displacement on the loading surface of a vehicle. The load securing means is here formed as a square tube and is fixed by means of two welded bolts in perforated rails in the floor of the wagon so that the square tube is directed substantially parallel to the longitudinal axis of the vehicle. The bolts welded on the square tube are arranged in pairs, with one bolt at its free end having a nose.

When the square tube is loaded along its longitudinal orientation and transversely to the longitudinal axis of the car, the first bolt rests on the edge of its arresting bore in the perforated rail, while the second nose stud engages behind the perforated rail and thereby prevents the square tube from tipping.

In the known apparatus, the holes in the perforated rail have a larger diameter than the bolts in order to ensure better insertion of the bolts into the holes. Thereby, the locking means has a certain play after being introduced into the openings of the perforated rail, so that it can self-release from its anchoring. Thus, with the known cost securing, the problem arises that the cargo securing means is not sufficiently secured against release from its anchoring.

US-A-3 633 516 discloses a securing device for securing loads on a transport vehicle, in which column-like securing elements are used which are anchored in receptacles in the loading surface of the transport vehicle. The bearing elements comprise bar locking elements which are welded on two opposite sides of the bearing elements. For anchoring, the receiving elements are inserted into the locking devices, wherein the rod-like locking elements engage the hook-like fastening pieces arranged opposite each other in the locking bars.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a load securing device on a transport vehicle against lateral displacement, in which the load securing means can be mounted on the loading surface of a relatively large load vehicle and securing the securing means sufficiently against being released.

Said task is solved by a load securing device on a transport vehicle with at least one locking device which is formed in the form of a rail comprising a first rail and a second rail and arranged in the loading surface of the transport vehicle and with at least one securing means which is one retaining element anchored in the arresting device, wherein the retaining element comprises at least one beacon cam for securing the securing means against transverse displacement and inclined in the arrested position, and at least one securing cam for securing the securing means against self-releasing and loosening according to the invention, whose essence lies in

The first locking device has notches on the edge section and the second locking device has a straight section and the locking cam engages in the notches of the locking device.

Thus, the locking means anchored in the arresting device in the loading surface of the transport vehicle comprises at least one retaining element which is introduced into the arresting device, the retaining element comprising as at least one securing cam which engages the arresting device. In this way, the possibility of easy mounting of the securing means in the arresting device is combined with securing the securing means against lateral displacement and tipping as well as against spontaneous release.

In fact, the locking means can be mounted in the locking device in a simple manner by means of a retaining element, the locking cam provided on the retaining element transversely to the longitudinal axis of the car when the locking means is loaded by the goods.

At the same time, by means of a locking cam arranged additionally on the holding element, an excellent locking is achieved against the spontaneous release of the locking means. The locking cam is arranged on the retaining element in such a way that it is permanently engaged with the locking device and thus effectively prevents the locking means from being released and raised.

According to a preferred embodiment of the invention, the locking means has a longitudinal contour, for example in the form of a beam or a tube. A wide loading surface for the goods to be loaded is thus provided along the longitudinal securing means, so that an effective securing of the transported load in the gravel direction is guaranteed at a lateral displacement. The provision of a U-shaped securing means has proved to be particularly advantageous in this respect, whereby a retaining means can be fastened in the region between the legs of the U-section.

According to the invention, it is further proposed that at least one recess is provided in the loading surface, which serves as a storage recess for the securing means which is not in operation. In the stowage recess, the securing means currently not usable for securing the load to be conveyed can be stored and ready for subsequent use.

It has proved to be advantageous to provide the means for securing the securing means in the storage recess with thighs. In this case, the securing means are located in the receiving recess on the dowels, so that the retaining element arranged on the securing means lies within the securing recess in the region between the two dowels. In this way, it is possible to achieve such an arrangement of the locking means in the storage recess that the upper side of the locking means is at the level of the loading surface of the vehicle. The danger of displacement of the discontinuous locking means is thus eliminated, since the parts protruding over the mattress platform are eliminated and the discontinued locking means are reliably stored in the receiving recess.

For better handling of the locking means, it has proven advantageous to provide the locking means with at least one recess that serves as a manual clip. By means of the retaining recesses provided, the locking means can also be gripped without problems even when it is at the depth of the storage recess. By means of hand clips, the securing means can be easily lifted out of the storage recesses as well as easily positioned in the locking devices.

As already mentioned, the locking device is in the form of a rail. Such locking rails can be easily integrated into the floor of the wagon so that they are essentially connected to the loading surface. In this case, the locking rail can consist of a first and a second rail, whereby a passage slot is formed between the two rails, into which the retaining element of the locking means can be easily inserted, thereby engaging the locking device.

In order to form the edge sections of the strips, it has proven advantageous if the first strip has notches or recesses on its edge section and the second strip, on the other hand, has a straight edge section. The edge section of the first rail is provided opposite to one another in the arresting rail and has a substantially straight, straight edge section of the second rail.

On the one hand, the introduction of the locking cam into the arresting device is facilitated by notches or recesses on the edge section of the first strip. Furthermore, the straight edge section on the second bar ensures a reliable engagement of the locking cam behind the locking device, thereby effectively preventing the release of the locking means from its anchoring.

In order to secure the locking means in the locking device, it is advantageous if the locking cam engages in one of the notches of the locking rail. As a result, the blocking cam, when the load-carrying means are loaded with the goods being loaded, can be brought into its first serrated rail with its preferably arranged free end at its free end and effectively locks the securing means against sliding and tilting.

Upon introduction of the retaining element into the arresting device, the spontaneous release of the securing means from the arresting device is prevented by engaging the securing cam beyond the straight edge section of the arresting rail.

According to a further preferred embodiment of the invention, the locking cam and the locking cam are arranged on the opposite sides of the holding element, offset from one another. This arrangement guarantees both the easy insertion of the retaining element into the arresting device and the anchoring of the securing means secured against release.

For a simple and cost-effective production, it has proven advantageous to form the locking cam and / or the locking cam in one piece with the retaining element. The locking and / or locking cam with the retaining element forms a compact and stable building unit.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 shows a load securing device for a transport vehicle 14 according to the invention in a mounted state on a loading surface 13. As can be seen from the plan view of FIG. 1, the device consists of a plurality of locking devices 2, which are arranged on the longitudinal sides 16, 17 of the car, perpendicular to the longitudinal axis 15 of the car. On the longitudinal side 36.17 of the wagon there are in each case six locking devices 2 in a perpendicular direction to the longitudinal axis 15 of the wagon. The individual locking devices 2 are designed in the form of rails and are fixed in the floor 18 of the vehicle 14 so that they do not protrude over the surface of the floor 18 and the loading surface

13th

In addition, six longitudinal load securing means 1 are anchored in the locking devices 2, in FIG. 1 not shown. Each securing means 1, in the present case in the form of a beam, is mounted in two spaced apart locking devices 2, so that the securing means 1 extends substantially parallel to the longitudinal axis 15 of the car.

The device mounted on the loading surface 13 thus consists of side-by-side securing means 1 arranged in parallel to the longitudinal axis 15 of the car, which are anchored in the locking rails 2 integrated in the loading surface 13 of the vehicle 14. in the direction of the securing means 1 anchored in the floor 18 secured against transverse displacement over the loading surface 13.

On the longitudinal sides 16,11 of the wagon there are stacking recesses 3 into which the securing means 1, which are not currently necessary for securing the load, can be stored and stored.

Fig. 2 is a side view of the wagon along line II-II of FIG. 1 with wheel 23 and spring tailstocks 24. The floor 18 is arranged on the underside of the support 18 in a transport vehicle 14. The upper side of the floor 18 forms the loading surface 13 of the transport vehicle 14. As shown in FIG. 2, holes 22 are provided in the floor 18 to accommodate the locking devices 2.

Fig. 3 is an enlarged view of a plan view of the apparatus of FIG. 1. The load securing device shown comprises two parallel locking and spaced apart locking devices 2 and a first longitudinal locking means 1, which is anchored in two places in one locking device 2.

The locking device 2 formed as the locking rails are arranged perpendicular to the longitudinal axis 11 of the car on the floor 18 of the vehicle 14, the first securing means 1 extending transversely to both the locking devices and along the longitudinal direction of the car. At the ends of the locking devices 2 arranged on the longitudinal side 11 of the car, there is a second securing means 1, which extends along the longitudinal side 17 of the car and is accommodated in the storage recess 3.

In contrast to the first securing means 1, the second securing means 1 is not anchored in the locking devices, but lies loosely in the storage recess 3 on the dowels 8. The second securing means 1 is not present in the present situation, but can be introduced into the locking device if necessary 2 to secure the goods located in the loading area 13.

As further evident from FIG. 3, the rail locking device 2 consists of a first bar 11a of a second bar 12 which are arranged parallel to one another. In this case, the first strip 11 has on its edge section 25

Directed towards the second bar 12 of the notch 7 or recess, so that a substantially toothed edge section 25 is formed. In contrast, the edge section 26 of the second bar 12 is opposed to the toothed edge section 25 of the first bar formed substantially straight. The two strips 11, 12 form a gap 27 between their edge sections 25, 26, into which a retaining element 4 of the securing means 1 is inserted.

The locking means 1 shown in FIG. 3 can be displaced along the slot 27 parallel to the longitudinal axis 15 of the car and anchored at the desired location in the locking devices by means of rupture elements 4. For this purpose, for example, the second locking element 1 can be provided by two recesses 9 arranged in the locking means 1 the grips, raised, with the retaining elements 4 located on the underside of the locking means 1, introduced into the locating devices 2 and parallel to the longitudinal axis 15 of the car in the locking devices 2 by means of the locking cam 6 arranged on the retaining element 4.

At the desired distance from the longitudinal axis 15 of the car, the locking means 1 can then lower and, with the locking cam 5 located on the retaining element 4, be introduced into the notch 7 of the locking device 2 and stored there. In this way, the locking means 1 can be anchored in the locking device 2 at any distance from the longitudinal axis 15 of the car.

In FIG. 4 shows the locking device 2 with the retaining element 4 and the locking means 1 in cross-section. The floor 18 mounted on the support carrier 19 has a recess 28 on its upper side. In the recesses 28 a first strip and a second strip 12 of the arresting device 2 are arranged so that the upper sides of the strips 11, 12 are substantially flush with the loading surface 13. 12 are fastened in the floor 18 by means of screws 29 such that their opposite edge sections 25, 26 grip the slot 27.

Above the floor 18 there is a securing means 1, on the underside of which the retaining element 4 is screwed. The retaining element 4 has on its side shown in FIG. 4, the locking cam 5 and the locking cam 6 on their right side. The locking cam 5 and the locking cam 6 are integrally formed with the retaining element 4 and form a building unit with the retaining element 4.

In this case, the locking cam 6 is located on the holding element 4 above the locking cam 5, so that both cams are formed on the holding element 4 at different heights. The locking cam 6 is arranged below the second bar 12 with a straight edge section 26 and its function is to secure the locking element 1 against lifting and loss. On the other hand, the locking cam 5 engages in the first bar with the toothed edge section 25 and by its engagement prevents the locking means 1 from being displaced in the transverse direction or tilting out of the loading surface 13.

In plan view, FIG. 4 shown in FIG. 5 shows the engagement of the retaining element 4 with the detent device 2. The retaining element 4, which is located on the underside of the securing means 1, is inserted in the slot 27. The securing cam 6 thereby moves below the straight edge section 26 of the second bar. On the opposite left side of the holding element 4, a locking cam 5 is offset in the longitudinal direction of the holding element 5. The locking cam 5 engages a recess or notch 7 of the toothed edge section 25 of the first bar 11, the nose 10 formed at its free end engaging the end Notched area 30 of the notch 7. When the goods are loaded transversely to the longitudinal axis 15 of the car, the locking cam 5 with its nose 10 engages the end region 30 of the first bar 11a, thereby securing the locking means 1 against transverse displacement.

Fig. 6 is a cross-sectional view of the apparatus of FIG. 5 along section line VI-VI. The securing means 1 is substantially U-shaped in cross-section, with a retaining element 4 screwed on the inside of the securing means 1 in the region between the two arms of the U-profile. The retaining element 4 engages the detent device 2, the locking cam 5 being in the recess or notch 7 of the first strip 11, and its nose lies below the edge region 30 of the notch 7.

At the lower end of the holding element 4, FIG. 6 shows a locking cam 6 which is located on the rear side of the holding element 4 perpendicular to the drawing. In this way, the locking cam 5 and the locking cam 6 are arranged on the holding element 4 at different heights as well as on opposite sides of the holding element 4 at substantially right angles to the holding element 4. This different arrangement of the locking cam and the locking cam on the holding element simply inserting the retaining element 4 into the arresting device 2, moving it in a controlled manner along the slot 27 by means of the locking cam 6, and finally locking the locking cam 5 in the notch 7 of the arresting device 2.

In FIG. 7 is a cross-sectional view of the device of FIG. 5 along section line VII-VII. The locking device 2 opens at its end towards the longitudinal sides 16, 17 of the car into depressions 31 in the loading area 13. The recess 31 serves as a storage recess 3 for the currently unused locking means 1. By moving the locking means 1 towards the longitudinal side 16,17 the retaining element 4 sinks into the recess 31, and thus the locking means is deposited in the receiving recess 3.

In the receiving recess 3, the securing means is located on the dowels 8 so that the upper side of the securing element lies flush with the bearing surface 13. The locking element 1, currently inoperative, can be fixedly and reliably mounted in the storage compartment 3. Furthermore, the locking means 1 can be quickly moved to the functional position on the longitudinal side of the car at low cost directly from the storage compartment 3 into the storage compartment. and, if necessary, install it.
