CZ359692A3 - sliding roof, particularly for trucks, semi-trailers and trailers - Google Patents

Abstract

The sliding roof for freight road vehicles consists of a pair of longitudinal bearers of supported posts along the sides of the body and serving to lead the trucks or wheels with jointed pairs of spars of articulated construction, on which cross bars are mounted, supporting the canvas, whereas the longitudinal bearers are formed as integrated profiles (1), whose guide section (7) is situated on the inner side of the support section (3). The support section exceeds the guide section and cross bars (12) by its ends protruding above the support section (3). Between the cross bars (12) and longitudinal supports (3) there is preferably a gap (x) when in the extended position.<IMAGE>

Description

Folding roof, especially for trucks, semi-trailers and trailers

Technical field

BACKGROUND OF THE INVENTION The invention relates to a movable roof, in particular for trucks, semi-trailers with trailers, which consists of a pair of longitudinal beams supported by pillars on the sides of the hull and serving to guide trolleys or pulleys with articulated pairs of scissor braces.

BACKGROUND OF THE INVENTION

To cover the hull of trucks, folding tarpaulins supported by transverse beams mounted on scissor struts are rotatably mounted on rails on the longitudinal beams of the tops of the hull, see e.g.

nc patents 17 Cu 141 or

17 3S5. A disadvantage of these known solutions is the low stability of the scissor structure, which is manifested by deformation of the struts when the sail is loaded by, for example, a layer of snow. Known folding roofs are also susceptible to deformation under lateral forces. Deformation.-scissor construction deteriorates the mobility of the roof or eliminates it completely.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a folding roof structure for truck bodies which can withstand vertical and lateral forces while being easily crushed from available materials.

SUMMARY OF THE INVENTION

The aforesaid trucks, semi-trailers and trolleys or tasks solve the folding roof; towers of the pillars on the sides of the hull sheaves with articulated joints;

ha, in particular for a camouflage of longitudinal beams and serving for guiding pairs of struts of scissor structure to which the transverse beams supporting the sheet are fixed, the essence of this roof being that its longitudinal beams are formed as an integrated profile consisting of a supporting part and a guide portion, wherein the support portion exceeds the guide portion and extends below the crossbeams.

In a preferred embodiment of the folding roof, a gap of 3 to 15 mm remains in the expanded position of the scissor structure between the upper side of the profile support section and the crossbeams.

The support part of the integrated profile may advantageously consist of two closed profiles placed one above the other and connected by an intermittent web, the guide part being located on the inside of the support part.

The outer strut may be shaped such that, in the expanded position of the scissor structure, the inner side of the support portion of the integrated profile closely fits.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be elucidated by means of the drawing, in which, in FIG. Fig. 2 is a double view of the same structure in longitudinal direction.

An example of an embodiment of the invention

The structure of the folding roof is formed by a pair of longitudinal beams formed as an integrated profile 7, which are supported by columns 2 on the sides of the hull. The integrated profile 2 consists of a support part 2 formed by two closed profiles 4. »

3, which are welded with gaps between closed profiles. A guide portion 2 formed by an open square profile is welded to the inner profile 2 of the support part 3 on its inner side. In the guide part 7, the carriages 2, on which the scissor-like struts 2, 12 are articulated at one end, travel. Always two parts * 7

The seat struts 9, 10 fastened to two adjacent carriages 30 are articulated to each other by the other end. The other end of the strut 2 is bent to form a bracket 11 for attaching a crossbeam 12 to support the sheet. The strut 2 is shaped so that in the extended position the outer side 22 sealingly passed the inner side of the carrying part 2 · End of cross beam 12 extends over the supporting portion 2 of the profile and between its lower edge and the upper side of the carrier body 2 with the gap of ² _x. This arrangement provides the necessary tension in the structure.

Rake roof is designed especially for truck bodies? road vehicles.
