DE764700C - Self-supporting car body, open on two neighboring sides, for vehicles of all kinds - Google Patents

Description

The invention relates to a self-supporting car body that is open on two adjacent sides For vehicles of all kinds, the walls of which have a rectangular or roughly rectangular plan delimit rectangular cargo space at or near the edges of the open box sides around at least three corners around stiffeners are led around the outside, which wholly or approximately to the neighboring corners of the Sufficient cargo space and in each case on the level

on the open side of the box or parallel to it, according to patent 708 052.

According to the invention, the subject matter of the main patent is intended to be further developed be that on its front end wall a box-shaped open top and front Formation is provided, the one around the front lower corners in the front plane led around stiffening edge reaching up to the adjacent upper corners

has, and that under certain circumstances the stiffening edges on the upper edges of the Load space extended to the front stiffening edge of the front structure and if necessary, the outer stiffening edges are flanged at their edges are.

According to the invention can also be a between the cargo space and the additional structure

jo at the top open center box should be provided, which at the top edges through to the stiffening edges of the cargo space and the additional structure adjoining edges and transverse edges is stiffened.

The inventive development of the car body according to the patent 708052 has the basis that on the closed end wall of the car body a box-shaped Structure is attached, which like the wagon

ao box of the main patent is open on two neighboring sides, namely at the top and at the front. To the Stiffening of the two lower front corners of the additional box-shaped structure a stiffening edge is led around it, which extends to the two front upper corners of the end face of the box extension enough. Furthermore, for stiffening at least one of the two upper corners, each of which is extended by one Side wall of the cargo space and its front wall are formed in and of itself used the existing stiffening edge of the cargo space.

A torsion-resistant car body with a torsion-resistant box extension provided is known per se, but z. B. with car bodies that are not on two adjacent sides, but only on one side, namely at the top, are open or otherwise deviate, e.g. B.

Are tubular closed, so in any case do not belong to the type of car body, which the main invention and embody the present invention. On the other hand, there are also those already known Box extensions according to the invention attached to the main box serving as a cargo space Structures are not the same, because those are not on two neighboring sides, but only on one side open.

Compared to the car body protected by the main patent is due to the invention the technical progress achieved that through the additional arranged in front Box increases the usability of the vehicle. The structure attached to the front of the cargo space can be used to accommodate the driver, the vehicle engine and for other purposes. As a result of The use of the means provided for in the main patent is used to make torsion-proofing a box extension known per se is particularly simple. The whole structure becomes a unified one and is easier to see and produce cheaper than before.

The drawing illustrates several exemplary embodiments of the invention in FIGS. 1 to 3 in a simple graphical representation.

Fig. Ι shows the right of the side walls / and I ₁ , the end wall k and the bottom m consisting of the main box with open top α and open back b, which is made torsion-proof that the outside around three corners, namely around the rear bottom corners d, e and around an upper front corner c stiffening plates g and / are placed around. By lengthening the side walls / and I ₁ and the floor m to the front, a front car body extension with an open top a ₁ and an open end b _{x is} created.

The structure built in front of the hold is made torsion-resistant in that around the front floor corners d _v e _x around in or near the plane of the free end face b _i a sheet metal ^ _{1 is} attached, which according to the stiffeners g, f of the main patent up to or near reaches the neighboring corners. A third corner c of the front box-shaped structure is stiffened by the part C _{1 of} the edge reinforcement / of the main box. This third corner forms although no neighboring corner of one of the ^λ both stiffened by the stocking ^ ₁ corners U ₁ and e but _v, it has been found that the stiffness of the main box is sufficient, the front extension f even at these triangles stiffening including the main box stiffening torsion resistant close.

In the embodiment according to FIG. 2, a cutout I is made in the front piece of the bottom m , which is framed over its entire extent by the stiffening ^ _1. For the main box end wall k attached to the rear edge of the stiffener C ₁ , dashed lines indicate that the wall can be at 90 ^° or at an angle to the floor m that deviates therefrom.

According to Fig. 3, a top open center box is provided between the main box and its front extension, which is formed by the bottom m, the side walls I, I ₁ and the vertical or inclined end walls k, U ₁ . The stiffeners ff ₂ , Z ₁ - ^ ₈ , C ₁ and C ₂ make the middle box torsion-proof. This increases the possibility of using the whole thing and makes the whole box even stiffer and more resistant than it is otherwise.

The front box-shaped structure can be completely or approximately rectangular or also have a tapered ground plan.

Instead of one, several middle boxes can also be arranged.

Claims (2)

Patent claims: i. Self-supporting car body, open on two adjacent sides, for vehicles of all kinds, the walls of which delimit a loading space that is rectangular or roughly rectangular in plan, in which on or near the edges of the open box sides around at least three outer corners are stiffeners, which completely or approximately up to the neighboring corners of the cargo hold extend and to lie in the plane of the open box side or in parallel, according to Patent 708 052 characterized in that at its front end wall (k) is provided a box-shaped, upwardly and forwardly open structure that a to the front lower Corners (^ ₁ , C ₁ ) in the forehead plane, extending to the adjacent upper corners has stiffening _{edge (^ 1} ), and that under certain circumstances the stiffening edges on the upper edges of the cargo space are extended to the front stiffening edge of the front structure and possibly the outer stiffening edges are flanged at their edges. 2. Car body according to claim 1, characterized in that between the cargo space and the additional structure an open-top center box is provided, which is connected to the stiffening edges of the cargo space and the additional structure at the top edges and transverse edges (C ₁ , C ₂ ) is stiffened.
