Description

CORNER FITTING FOR KISTEN-ASSISTANT STRUCTURES ON TRANSPORT PALLETS

The invention relates to a corner fitting for box-like structures on transport pallets, each of two side wall elements stackable side wall frame of the box-like structure via a hinge connection along a hinge axis interconnects and has an alignment element for alignment of the side wall frame relative to the transport pallet or to another, adjacent side wall frame, according to Preamble of claim 1.

Transport pallets are used to carry larger goods and are mostly made of wood. They are also referred to as "Europaletten" or "Europoolpaletten" and consist of floorboards and cover boards, which are interconnected via intermediate blocks. Between the floorboards and the deck boards remains a space in which the tines of a truck, forklift or a lift truck can be introduced to move the transport pallet subsequently over shorter distances, such as for loading onto a truck or wagon.

For the transport of loose goods, bulk or delicate goods box-like structures are arranged on the transport pallets by means of side wall elements, which are bounded below by the cover boards of the transport pallet, and upwards of the floorboards of a possibly above stacked, further transport pallet. For this purpose, the side wall elements are mostly pivotally connected to one another via corner fittings, in order to be able to fold them together in the absence of need and store them in a space-saving manner. Each four side wall elements form a, closed in the peripheral region side wall frame, can be stacked on the other side wall frame until the box-like structure has reached a desired height and is completed upwards from another transport pallet. In turn, further side wall frames can be arranged on this uppermost transport pallet.

The side wall frames must be aligned in their stacking relative to each other, but also relative to the transport pallet. Conventional corner fittings for this purpose have alignment elements in the form of outer Ausrichtlappen, which protrude parallel to the hinge axis down. In the position of use these Ausrichtlappen are close to the tapered in the corner outer surfaces of the underlying transport pallet or the underlying side wall frame tight.

Although alignment tabs of the conventional type are simple in design and widely used, they have some disadvantages in practice. For example, they protrude beyond the outer surface of the transport pallet and the side wall elements and are therefore heavily used in practice. Transport pallets must be tightly loaded for their transport not only for reasons of optimal space utilization, but also for reasons of cargo safety become. As a result, alignment tabs often catch on other parts or other alignment tabs and are subsequently bent up. These straightened Ausrichtlappen complicate the further handling of the transport pallet and often lead to damage to other parts. Subsequently, straightened Ausrichtlappen be bent back consuming, which delays the entire loading process.

Furthermore, conventional alignment members do not provide a high tensile strength connection, so an assembly of stacked shipping pallets and sidewall frames must be finally wrapped with straps to prevent vertical movement during shipping. These straps are mostly made of plastic and are cut open and disposed of after use. Therefore, they not only cause great time for the bracing, but also a lot of waste.

It is therefore the object of the invention to avoid these disadvantages and to realize a corner fitting, which allows easy mutual alignment of sidewall frames and transport pallets and facilitates the repeated assembly of box-like structures on transport pallets and their loading.

These objects are achieved by the features of claim 1. Claim 1 relates to a corner fitting for box-like structures on transport pallets, the two side wall elements stackable side wall frame of the box-like structure via a hinge connection along a hinge axis interconnects and has an alignment element for aligning the side wall frame relative to the transport pallet or to another, adjacent side wall frame. According to the invention, it is provided that the alignment element is designed as a, perpendicular to the hinge axis between a locking position and a release position movable locking element which is arranged in a first end portion of the hinge connection, and in the opposite, second end portion of the hinge connection a receiving pocket with a locking opening for the Locking element of another corner fitting is provided. The lock acts between two superimposed corner fittings, or a corner fitting and the transport pallet, as will be explained in more detail. Since the inventively provided alignment element is movable perpendicular to the hinge axis between a locking position and a release position, the locking acts under load in the direction of the hinge axis and thus in the direction of the corner edge of the side wall frame movement inhibiting, and thus constitutes a tension-resistant connection. Straps and the like for vertical fixation are therefore no longer required. Furthermore, over the outer surfaces of the side wall frame and the transport pallet protruding parts can be avoided. The locking element can be embodied as a locking bolt guided in a housing and prestressed perpendicularly to the articulation axis.

As already mentioned, the box-like structure can be completed upwards from another transport pallet. In order to ensure alignment relative to this transport pallet, it is further proposed that a cover plate is provided which has a cone-shaped extension projecting parallel to the joint axis. This extension can engage in a corresponding Konsuförmige recess in the floorboards of the overlying transport pallet, so that a relative orientation is ensured.

The invention will be explained in more detail below on the basis of exemplary embodiments with the aid of the enclosed figures. It show here the

Fig. 6 is a perspective detail view of an embodiment of a locking plate for receiving the locking element by a transport pallet.

Reference is first made to FIG. 1, which shows an arrangement of two transport pallets 1, each with two side wall frames 2 stacked thereon, with corner fittings 5 according to the invention. The transport pallets 1 consist of floor boards and cover boards 4, which are connected to each other via intermediate blocks 3. A side wall frame 2 consists of four side wall elements 2.1, 2.2, 2.3, 2.4, of which only two side wall elements 2.1, 2.2 are visible in FIG. The four side wall elements 2.1, 2.2, 2.3, 2.4 of a side wall frame 2 are hinged together via four corner fittings 5.1, 5.2, 5.3, 5.4. Each side wall frame 2 is open at the bottom and at the top, wherein a plurality of side wall frames 2 can be stacked one above the other and bounded below by a lower transport pallet 1.1 and upwardly by an upper transport pallet 1.2. Furthermore, the 1 that the corner fittings 5 have no projecting beyond the outer surface of the transport pallets 1 and the side wall elements 2 parts. This situation is made possible by the fiction, contemporary design of the corner fittings 5, as explained with reference to FIGS. 2 and 3.

2 shows a perspective detail view of an embodiment of a locking element 6 according to the invention, which is mounted displaceably within a housing 7. The housing 7 is in turn secured to a housing holder 8, which is integrally formed on the corner fitting 5 or attached to the side wall element 2.2. Furthermore, in FIG. 2, a hinge connection 9 of the corner fitting 5 can be seen, which defines a hinge axis A, as better seen in FIG. 3. The locking element 6 is designed as a, guided within the housing 7 and biased perpendicular to the hinge axis A locking bolt which is perpendicular to the hinge axis A between a locking position and a release position movable.

The locking element 6 is arranged in a first end region of the articulated connection 9, in the example of FIGS. 2 and 3 in the lower end region, and engages in a receiving pocket 10 of a further corner fitting 5 (see FIG. 3), which at the opposite, second end region of FIG Articulated connection 9 is arranged. A corner fitting 5 thus has a locking element 6 in a first end region of the articulated connection 9, and a receiving pocket 10 in its opposite, second end region of the articulated connection 9, of course the locking element 6 of a first corner fitting 5 into the receiving pocket 10 of a further, adjacent corner fitting 5 intervenes. The locking bolt is first pushed back upon entering the receiving pocket 10 and finally pierces a locking opening 11 of the receiving pocket 10. That position of the locking element 6, in which it is retracted into the housing 7, is hereinafter referred to as the release position, and that position, in which the locking element 6, the lock s opening 11 of the receiving pocket 10 pierces, as a locking position. The receiving pocket 10 may be formed approximately at the corner fitting 5, or be formed by a cutout in the side wall element 2.2.

The box-like structure can be completed upwards from another transport pallet 1.2. In order to ensure alignment relative to this transport pallet 1.2 as well, a cover plate 12 is provided which has a conical extension 13 projecting parallel to the articulation axis A, as can be seen in FIG. This extension 13 engages in a corresponding, conical recess 14 (see Fig. 5), which is arranged in a floorboard of the overlying transport pallet 1.2, so that a relative orientation is ensured. The box-like structure can further be completed down from a transport pallet 1.1. In order to ensure alignment relative to this transport pallet 1.1, a locking plate 15 is provided, which is arranged in a cover board 4 of the underlying transport pallet 1.1, as can be seen in FIG. The locking plate 15 covers a corresponding cutout in the cover board 4 of the transport pallet 1.1 and can be engaged behind by the locking element 6. The locking plate 15 together with the cutout in the cover board 4 thus forms a receptacle for the locking element 6 analogous to the receiving pockets 10 described above.

The locking by means of engaging in the receiving pockets 10 locking elements 6 thus acts between two superimposed Eckbeschlägen 5. The locking by means of engaging in the locking plates 15 locking elements 6, however, acts between a corner fitting 5 and the underlying transport pallet 1.1. Since the fiction, provided according to alignment element is perpendicular to the hinge axis A between a locking position and a release position movable, the latch acts under load in the direction of the hinge axis A and thus in the direction of the corner edge of the side wall frame 2 movement inhibiting, and thus provides a high-tensile strength The like for vertical fixation are therefore no longer necessary, but it could the top cover plates 12, on which no transport pallet 1 is arranged more, are clamped diagonally by tensioning straps, including slots 16 are provided in the cover plates 12.

By means of the invention thus a corner fitting 5 is realized, which allows easy mutual alignment of side wall frame 2 and transport pallets 1 and facilitates the repeated assembly of box-like structures on transport pallets 1 and their loading.
