Box-shaped vehicle body, especially for a refrigerated vehicle

Abstract

A box-shaped vehicle body, in particular for a refrigerated vehicle, with a cargo space bounded by insulated walls, which has an opening that can be closed by a sectional door (1) having a plurality of pivotably connected panels (2) which are guided in guide rails (5), is designed such that the guide rails (5) are formed by groove-like recesses in opposing guide rail supports extending over the height of the opening, each of which is aligned with the outside of the closed sectional door (1) with its associated outer side.

Description

[0001] The invention relates to a box-shaped vehicle body, in particular for a refrigerated vehicle according to the preamble of claim 1.

[0002] Such vehicle bodies, which are primarily used for the transport of frozen goods, are well known. A characteristic feature of such vehicle bodies is the insulation of the walls, especially the side walls, as well as the sectional door that closes off an access opening to the cargo area.

[0003] This sectional door, which features a multitude of pivoting, interconnected panels, is guided on tracks arranged on a rear frame bordering the opening, on the side facing the cargo area. The panels have rollers at their ends that roll along the tracks when the sectional door is operated.

[0004] The disadvantage of this design, however, is that the clear width of the opening is reduced compared to the clear width of the loading space, which makes loading the loading space more difficult.

[0005] The usable length of the loading space is also reduced by the arrangement of the guide rail, which is designed as a separate guide bar, which also prevents optimal loading of the vehicle body.

[0006] In addition, the recess of the closed sectional door relative to the frame is often perceived as disturbing when viewed from the outside.

[0007] The invention is based on the object of further developing a box-shaped vehicle body in such a way that its loading space is increased overall.

[0008] This object is achieved by a box-shaped vehicle body having the features of claim 1.

[0009] The invention provides significant advantages over the prior art, particularly with regard to the use of the loading space of the vehicle body.

[0010] In one design variant, the guide rails are arranged in the side walls so that the clear width of the opening now corresponds to the clear width of the loading space, which on the one hand results in significantly easier loading of the loading space and on the other hand the usable area of ​​the loading space is larger than in a state-of-the-art design.

[0011] This also applies to a further embodiment of the invention, in which the guide rail support is formed by the side members of a rear frame. In this case, the rear frame can also support a shifted load that is pressing against the sectional door.

[0012] The further characteristic feature of the invention, according to which the track support is aligned with the outer sides of the panels when the sectional door is closed, results in an improvement in the overall view, since the rear view is perceived as a continuously closed, flat surface.

[0013] According to a further idea of ​​the invention, it is provided that the respective guide rail is arranged in a side wall segment which is firmly connected to the adjacent side wall, for example by gluing.

[0014] The guide rail is formed by a groove-like, preferably U-shaped cross-section recess of the guide rail support, whereby the outer skin of the guide rail support is manufactured as a sheet metal part and filled with insulating material, corresponding to the side wall.

[0015] To ensure that the outer side of the panels is aligned with the corresponding narrow sides of the track supports, each panel has a notch on the outside in the front area, into which a nose of the narrow side of the track support rests when the sectional door is closed.

[0016] In the same way, an aligned formation is provided in the area of ​​an upper end edge of the opening, which has a vertically aligned apron extending across the width of the opening, which is also provided on the outside in a notch on the upper edge of the upper panel, in which the apron lies with a facing edge area, whereby an aligned constellation is then created with the outside of the panel and the outside of the apron.

[0017] This alignment of the upper edge area of ​​the upper panel with the apron and of the guide rail support with the panel not only results in an attractive, non-disruptive external view of the rear of the vehicle body, but also insulates against the elements, whereby sealing measures can be provided in the common overlap area.

[0018] Each guide rail can also be positioned behind the rear frame on the side facing the cargo area. By notching the panels or the rear frame and the apron, the guide rail is positioned close to the rear frame.

[0019] Further advantageous embodiments of the invention are characterized in the subclaims.

[0020] An embodiment of the invention is described below with reference to the accompanying drawings.

[0021] They show: Fig. 1 Sectional door closing an opening of a box-shaped vehicle body in a closed position Fig. 2 a section through the sectional door along the line II-II in Fig. 1 Fig. 3 a section of the sectional door in a sectional plan view, according to the line III-III in Fig. 2 Fig. 4 an enlarged section of the Fig. 3 according to the indication A in Fig. 3 Fig. 5 an enlarged section of the sectional door according to the indication B in Fig. 2.

[0022] In the Fig. Figure 1 shows the rear view of a box-shaped vehicle body, in particular for a refrigerated vehicle, with a sectional door 1 closing an opening of the vehicle body, as shown in the example.

[0023] Insulated side walls define a loading space at the sides, while an opening to the loading space is defined by a rear frame, of which side members 3 are visible.

[0024] The sectional door 1 consists of a plurality of pivotally connected panels 2 which are guided longitudinally in guide rails 5, wherein the panels 2 are provided on their end faces with rollers 6 which are mounted in the guide rails 5.

[0025] According to a variant of the invention, the guide rails 5 are arranged in the side members 3 and are U-shaped in cross section, as can be seen particularly clearly in the Fig. 4 is recognizable.

[0026] The guide rail 5 is lined with a securing profile 7, which overlaps the associated roller 6 on one side and thus ensures safe guidance of the roller 6.

[0027] According to the invention, the associated outer sides of the side members 3 are aligned with the outer sides of the panels 2, for which purpose the latter have a notch 8 on the outside and in the outer edge area, into which a nose 9 of the side wall segment 3 projects.

[0028] In the Fig. 4, which shows an enlarged section A in this area, it can be seen that a seal 10 is arranged between the nose 5 and one of the surfaces of the notch 8.

[0029] The side member 3 is covered by a sheet metal part 4, whereby the securing profile 7 is also made of sheet metal.

[0030] In the Fig.5, which shows an enlarged section B of the sectional door 1, the upper edge of an upper panel 2 is also provided with a notch 8 towards the outside, into which an apron 11 positioned at the upper edge of the opening projects in such a way that the panel 2 is flush with the outside of the apron 11, whereby, in conjunction with the side members 3 or the side walls, a substantially flat surface of the vehicle body is formed.
