A transport frame that can also be stacked when loaded is disclosed, for example, in EP-B O 327 438. It consists of a rectangular lower frame and a rectangular upper frame that is open on one side and that are connected by vertical stands. Glass plates can be placed into this frame from the open side.

However, for the storage and transport of flat glass plates or glass plate packages in particular, so-called α-racks are more common, in which stands are inclined towards each other in pairs and form support frames so that glass plates, glass plate packages or the like can be placed from two sides.

DE-U 82 19 328 discloses A-shaped transport racks for flat objects, in which the packages of these objects rest on spacer beams that are provided for several such transport racks and that are arranged outside the transport racks, so that the transport racks themselves bear practically no load. For the stacking arrangement, the racks are therefore not stacked directly, but rather over the spacer beams. The transport racks are each positioned opposite one another with their inclined support surfaces for the packages, with an upper stack layer being offset in relation to the lower one in such a way that the undersides of the support blocks of the transport racks are located above the connection point of the support blocks of an A-shaped frame of the lower stack layer. The support blocks of the individual transport racks are cross-braced, so that space-saving stacking is not possible when unloaded.

that the transport frames themselves can be dismantled. The
The individual frame halves can then be stacked without load, but they always have to be assembled or disassembled, which is labor-intensive and time-consuming.

The design of DE-B 17 61 869 avoids transverse and
Longitudinal bracing between the uprights on which glass plate packages rest and stability is achieved through the selected profiling of the upright components. Although stacking arrangements can be formed in this way, the frames are extremely unsuitable for transport.

It is the object of the invention to create a simply constructed transport rack that can be stacked both when unloaded and when loaded, whereby the space requirement of the stack, especially for unloaded transport racks, should be kept as small as possible.

This object is achieved by a transport frame according to claim 1. Advantageous embodiments are the subject of the subclaims.

According to the invention, a large number of support areas and support areas are provided for each side of the system, which are connected to one another at least in sections, that the floor struts extend in one piece to the outer edges of the support areas, that the crossbar is lowered into the interior of the transport frame with respect to the upper edges of the support areas, that the floor struts and the feet are dimensioned in width such that they do not exceed the width of the crossbar or the clear width between the upper edges of the opposing support areas, and that a stop bar is provided on the underside of the support areas on their outer edge. The large number of support areas in particular means that the transport frame is very rigid, so that cross braces in addition to the floor struts and the crossbar are not necessary. When unloaded, the transport racks can therefore be easily stacked on top of each other, whereby the feet of each stacked rack should rest on the floor struts of the transport rack below. By choosing the appropriate length of the feet, it can also be ensured that the contact areas of the lower rack do not come into contact with the underside of the rack stacked above, so that any paint or protective coating applied to the contact areas is not damaged. When loaded, the transport racks can be stacked in an arrangement such as that already shown in DE-C 31 31 109. However, the invention does not require complex joints such as those used in the stand.

BOEHMERT & BOEHMERT, NORTHERN PARTNERS

technology is not necessary. The stop bar on the underside of the support areas reaches behind the upper edges of the support areas and prevents the stacked transport rack from slipping. With the transport rack according to the invention, another stacking arrangement is possible in which the upper, stacked transport racks are rotated by 90° relative to the lower ones. This is achieved by the dimensioning of the floor struts, the feet and the crossbar selected according to the invention, which enables the floor struts and feet to engage in a channel formed by the support areas and the crossbar.

In order to achieve a higher stability of the arrangement, especially in the last stacking variant, it is advantageous to provide openings in the crossbeam which are dimensioned such that they correspond to the dimensions of the feet in terms of width and depth.

According to a preferred embodiment of the invention, each side of the support is designed as a solid surface with profiles arranged on it, whereby the outward-facing surfaces of the profiles form the support areas and/or the standing areas. The profiling of the frame, especially in the large areas on which the objects are placed, contributes significantly to the stability of the frame.

The full-surface connection of the profiles is advantageous from a constructional point of view, but not absolutely necessary from the point of view of the inventive concept. It can be equally advantageous to provide a large number of profile strips on each side of the system, which are at least fixed to the crossbeam, whereby the outward-facing surfaces of the

BOEHMERT & BOEHMERT, NORDEMANN and PARTNERS

Profi1 provides the investment areas and/or the uprising areas form.

It has been shown that the profiles or profile strips are best designed to be trapezoidal in cross-section.

In order to protect particularly sensitive surfaces of glass or plastic panels from damage, e.g. scratches, etc., the outward-facing surfaces of the profiles or profile strips should at least be provided with a protective coating in some areas, for which polyurethane has proven to be a suitable material.

In the following, the invention will be explained in more detail by way of example with reference to the accompanying drawings.

Figure 8 shows the arrangement of Figure 7 in a view rotated by 90°; and

Figure 9 is a detailed view of Figure 8.

The transport frame for flat objects shown in Figure 1 has two opposing support sides 10, 20, each of which consists of a plurality of support areas 12 and 22 and support areas 14 and 24. Support areas 12, 22 and support areas 14, 24 are aligned at right angles to one another, with support sides 10, 20 tilted towards one another and support areas 12, 22 forming an acute angle with one another, but remaining spaced apart from one another in their upper section. In this upper area, slightly below the upper edges of support areas 12, 22, a crossbar 30 is arranged, to which support areas 12, 22 are fixed. A profile strip 32 is provided below crossbar 30, which serves to further stabilize the arrangement. Outside the installation and support areas, a floor strut is provided, of which only the rear one 40 can be seen here, which is therefore attached to the rear end of the transport frame. The floor strut 40 rests on two feet 42, 44. Between the two floor struts, an angle profile 16, 26 is attached to the underside of the support areas 14, 24 in such a way that one leg of it extends away from the outer edge of the support areas 14, 24. The support areas 14, 24 are fixed to the other leg, so that the angle profile forms a stabilizing bar for the frame on the one hand, and a stop edge or stop bar on the other hand, as will be explained further below. The floor struts 40 are dimensioned in height so that their upper edge is approximately at the outermost area with

BOEHMERT & BOEHMERT, NORDEM*ÄNN and PARTNERS

the respective uprising areas 14, 24.

Figure 2 shows four such A-shaped transport racks A, B, C, D, which are stacked on top of one another without any load. The feet of rack A, for example, stand on the floor struts of rack B, etc., with the length of the feet being chosen so that the contact areas and support areas, which may be provided with a protective cover, do not come into contact with the rack arranged above them. This stacking method "like little hats" allows the best use of space to be achieved.

Figures 3 to 6 show a first type of stacking for loaded racks. The objects placed on them are not shown for reasons of clarity. The stacking arrangement here consists of three transport racks E, F, G (Figure 5); it can be extended almost as desired and its height is limited by the load-bearing capacity of the racks themselves. Figure 3 shows a top view of the installation areas. Profiles 18, 18' can be seen very clearly, even better in Figure 4, which form the installation areas and, as Figure 5 also shows, the support areas. The profiles 18, 18' are trapezoidal in cross-section and, apart from the inclination of the installation areas, are arranged essentially vertically on a solid surface 50 or 50', which forms the connection for the profiles 18, 18' and which also extends under the support areas of the profiles 18, 18'. Outside the solid surfaces 50, 50', the floor struts 40, 46 and 40', 46' are arranged on both sides, whereby in the variant shown here the feet 42, 48 and 42', 48' are set back behind the surface of the corresponding floor struts facing the viewer. The angle profiles 16, 16' extend between the floor strut pairs 40, 46 and 40', 46', which in the stacking type shown here form a

BOEHMERT & BOEHMERT, NORDEMANN and PARTNERS

Define stop bar. This is shown in detail in Figure 6 for the support point of the transport frame F on the transport frame E. The downwardly projecting leg of the angle profile 16, which is attached to the underside of the support area 14, projects over the upper edge of the support area 22 into the interior of the transport frame E and ends just above the crossbar 30. The transport frame F therefore engages the section of the transport frame E that is particularly stabilized by the crossbar 30 and the profile bar 32. Furthermore, the second leg of the angle profile 16 lies on the upper side of the support area 22, so that the support area is not subjected to direct and linear loads. A corresponding support point is formed between the frames E and G.

Figures 7 to 9 explain the second way of stacking loaded transport racks. The same transport racks are used as in the variant in Figures 3 to 6, but the upper transport rack K of the stack is rotated by 90° relative to the lower racks H, J. Figure 8 shows how the floor struts 40, 46 with the attached feet 42, 48 of the rack K each lie in channels formed by the opposing contact areas 12', 22' or 12", 22" and the crossbar 30', 30" in between. It can be seen in particular in Figure 9 that, for example, the foot 42 engages in an opening 34" in the crossbar 30", so that the upper rack K is particularly securely secured against displacement or slipping.

The features of the invention disclosed in the above description, in the drawings and in the claims may be essential for the realization of the invention both individually and in any combination.
