Loading frame

The invention relates to a loading frame made of vertical, U-shaped rigid posts and one or several horizontally attachable, likewise U-shaped support beams, the posts and the support beams being connected to one another by means of a connection without bolts which connection is such that an unintentional loosening of the same is largely impossible while achieving great stability between the incoming and interconnected elements will. Such a loading frame is used to place goods to be loaded.

A large number of loading frame constructions of these Kind are; confused, but mostly time consuming Montagevi> rgämge, and their manufacturing costs are also quite high.

The object of the invention is to provide a particularly stable and at the same time simple connection arrangement to create between the vertical post and the supporting beam, which also essentially reduces the risk prevents unintentional loosening during manual or machine handling, which reduces the struts that were previously were considered necessary for the sake of stability, can be avoided.

The loading frame according to the invention is characterized in that the support beams with at the end portions arranged, bent at approximately right angles and an opposing vertical post in the working position each at least partially enclosing end plates are provided, each of which has an IT flange with elements is provided which cooperate with elements attached to one side of the associated vertical post, that the attachment of the support beam can take place by a certain two-stage movement in which the lower elements of the girder first interacted with the elements of the vertical post after which an approximately horizontally directed force influencing the supporting beam creates an automatic interaction between the upper elements of the support beam and the post, with the second flange of the End plate arranged elements automatically in cooperation with arranged in the back part of the vertical post Fasteners are brought.

In the following description is an embodiment of the loading frame according to the invention described with reference to the drawing. Show in it:

Figure 1 is a view of a U-shaped vertical post seen from behind;

Fig. 2 is a view taken along the line II-II of Fig. 1;

3 shows the fastening plate arranged on the supporting beam with the associated fastening elements;

Fig. 4 and 5 the attachment of a support beam to a vertical post and

6 shows a support beam which is subjected, for example, to the attempt of a forklift, a to bring about unintentional termination of the connection.

A U-shaped vertical post 1o is on one

or two side sections with oblique eyelet-like or box-like elements 11, 11 'or 12, 12 located above each other approximately in the same vertical plane ^! provided, which are punched out directly from the material of the post 10 and which are open both at the top and at the bottom. In the exemplary embodiment shown, the rear side of the post 10 is provided with an inclined slot 13 or 14 on each side of the vertical dividing plane of the post 10.

A U-shaped support beam 15, which is intended for placing a load, is arranged so that he to be connected at the end sections with vertical posts of the type described above. The end sections of the support beam 15 are bent for this purpose

109828/1256 -4-

End plates 16 are provided which, in the operating position, at least partially enclose the vertical post 10 (FIG. 2). Due to the bent shape, the end plate 16 is provided with a first flange 17 and a second flange 18, the back flange educated. The flange 17 of the end plate has an upper inclined tongue 19 with a curved slide 19 '. The tongue 19 is, as is particularly apparent from FIGS. 1 to 6, within the U-shaped space of the support beam 15 arranged. At a distance a from the lower edge of the tongue 19 is a hook-shaped stop member 20 molded. The flange 17 is also provided with a lower, similarly inclined tongue 21. This tongue 21 has a length which is greater than the distance c, which in FIG. 3 is the distance between the stop part 20 and the eyelet 11 on the lower portion of the vertical post 10.

The back flange 18 of the end plate 16 has an inclined tab 22.

When attaching a support beam to a vertical post by means of a connection according to the invention, the lower tongue 21 on the flange 17 of the end plate 16 is first inserted into the lower loop-like element 11 ' of the vertical post 10 (Fig. 4) is introduced. In this first phase, the supporting beam is in one certain angle in relation to the vertical post. When the tongue 21 has been engaged with the eyelet 11 ' is, a displacement of the support beam in an approximately horizontal direction is required (arrow A in Fig. 5). Through this that the upper tongue 19 is formed with the curved sliding path 19 ·, this path becomes during the displacement slide against the upper edge of the eyelet 11 and then automatically engaged with this eyelet. The one above

109828/1256 -5-

mentioned slot 13 in the back part of the vertical post is at the same time when inserting the tongue 19 in the eyelet 11 has been automatically brought into cooperation with the tab 22 on the flange 18 of the end plate.

The connection is now complete and the loading frame is ready for its practical use without stiffening Back struts required for stabilization are, and this effect has been achieved by the shaping of the connecting elements and further " by the interaction, which leads to the fact that the load on a supporting beam acts in two planes that are mutually exclusive are at right angles.

The loading frame construction according to the invention not only has amazing stability, but also the connecting elements are also shaped in such a way that inadvertent loosening of the connection is almost impossible will.

This is an essential factor for safety reasons

is shown in Fig. 6, in which it is assumed that Λ the lifting forks of the forklift unintentionally affect the support beam 15 from below. If it is further assumed that the forklift also continues backwards in the direction of the loading frame structure, there is thus a force directed partly upwards and partly to the side, which in the process lifts the support beam. The lower tongue 21 on the flange 17 of the end plate 16 tends to come out of engagement with the eyelet 11 ', but this does not succeed because the distance c (the possible lifting height) between the stop member 20 and the lower edge of the upper eyelet 11 smaller let than the length of the lower tongue 21. Like it

109828/1256 -6-

6, the lower tongue 21 is retained in the engagement shown with the lower eyelet 11 '. The interacting slots and tabs 13, 22 naturally also contribute to an unintentional To prevent loosening of the connection.

Although the connection according to the invention relates in principle to one without bolts, e.g. B. if the currently applicable safety regulations should be changed at a later date, if necessary the Connection with a through hole for example in the flange 18 and a corresponding hole in the vertical Posts are added and a split pin is inserted through these holes, which is easy to attach and also to decrease.
