Abstract

The invention relates to an arrangement related to trailers of the type used for driving with so-called cassette trailer bodies and which are excelled by the fact that they are somewhat narrower than a usual lorry body and designed to fit inside such a body. The arrangement is excelled by the cassettes 1, 2, which are designed in such a way that the distance between their side walls 13 can be increased to normal body width for transport of pallet goods and similar. <IMAGE>

Description

i791ot1ss-ß i 2 10 15 zol 25 30 35 _ 40 kassettflaket med en enkel åtgärd göras bredare eller smalare allt.efter det föreliggande behovet och lämpligen omställer det naturligtvis excenteraxeln flakets samtliga sidostolpar. i791ot1ss-ß i 2 10 15 zol 25 30 35 _ 40 the cassette deck with a simple operation is made wider or narrower according to the present need and suitably it naturally adjusts all the side posts of the eccentric shaft of the deck.

I enlighet med en vidareutveckling av uppfinningen kan två kassetter vidare sammankopplas genom att ändstyckena fälls ner 'i form av luckor för att bilda ett lastplan vid körning av stycke- gods, varvid_lämpligen kassettväggarna är utförda som fällbara _lämmar.vilka vid gruskörning eller annan massgodskörning utnyttjas som väggar i en normalkassett. Kassettväggarna kan härvid utgöras av plywoodlämmar.In accordance with a further development of the invention, two cassettes can be further interconnected by folding down the end pieces in the form of hatches to form a load plane when driving piece goods, the cassette walls being suitably designed as foldable leaves which are used as gravel or other bulk goods as walls in a standard cassette. The cassette walls can in this case consist of plywood doors.

En utföringsform av uppfinningen skall nedan närmare beskri- vas under hänvisning till bifogade ritningar, där fig_l visar en schematisk sídovy av ett släpfordon med dubbla breddbara kasset- ter enligt uppfinningen. Pig 2 visar schematiskt en av de bredd- bara kassetterna sedd uppifrån. Pig 3 visar en genomskärning av en breddbar kassett enligt uppfinningen med flaket inställt som kassett. Pig 4 visar en vy som motsvarar vänstra delen af fíg 3 men där flaket är breddat för transport av Europa-pallar. Pig 5 visar ett snitt längs A-A i fig 4. Pig 1 visar alltså en sidovy av en släpvagn med två kassetter 1 och 2 enligt uppfinningen.An embodiment of the invention will be described in more detail below with reference to the accompanying drawings, in which Fig. 1 shows a schematic side view of a trailer with double widenable cassettes according to the invention. Pig 2 schematically shows one of the widenable cassettes seen from above. Fig. 3 shows a cross-section of a expandable cassette according to the invention with the platform set as a cassette. Fig. 4 shows a view corresponding to the left part of Fig. 3 but where the platform is widened for transport of European pallets. Fig. 5 shows a section along A-A in Fig. 4. Fig. 1 thus shows a side view of a trailer with two cassettes 1 and 2 according to the invention.

Som framgår av ritningen förenas de båda kassetterna ungefär vid mitten genom att_luckor 3 fällas ned och bildar_lastplan vid T körning av pallgods.As can be seen from the drawing, the two cassettes are joined approximately at the middle by folding down hatches 3 and forming a loading platform when driving pallet goods.

Som framgår av genomskärningen i fíg 3 bildas kassettflaket av en längsgående bärande balk 4 och av tvärgående balkar 5 som bildar underlaget för bottnar 6. Tvärbalkarna 5 är vid sina ändar (till.vänster i figuren) försedda med enkla lagringar 7 för rör 8 som kan skjutas ut och in i förhållande till fordonets centrallinje med hjälp av en excenteraxel 9, som sträcker sig i kassettens 1, 2 längdriktning. _ _ _ _ Vid den visade utföríngsformen ombesörjes förskjutningen av varje stolprör 8 av ett antal excenterbyglar 10, som givetvis kan utformas på olika sätt utan att uppfínningstanken frängås. 1 fig 4 visas röret 8 i utskjutet läge. Alla sadana rör på enfsida upp- bär en kantlina 11, som uppbär stolpfickor 12 för stolpar 13, som Ii sin tur uppbär lämsidor för styckegodskörning. I utskjutet läge (fig 4) har släpvagnen en invändig bredd, som är anpassad till Europa-pallen i första hand.As can be seen from the section in Fig. 3, the cassette surface is formed by a longitudinal supporting beam 4 and by transverse beams 5 which form the base for bottoms 6. The crossbeams 5 are provided at their ends (left in the figure) with simple bearings 7 for tubes 8 which can is pushed in and out in relation to the central line of the vehicle by means of an eccentric shaft 9, which extends in the longitudinal direction of the cassette 1, 2. In the embodiment shown, the displacement of each post tube 8 is provided by a number of eccentric stirrups 10, which can of course be designed in different ways without compromising the inventive idea. Fig. 4 shows the tube 8 in the extended position. All such tubes on one side support an edge line 11, which carries post pockets 12 for posts 13, which in turn support limb sides for hauling. In the extended position (fig. 4), the trailer has an internal width, which is adapted to the European pallet in the first place.

Stolparna 13 är lämpligen förenade med lämmar av plywood eller dylikt, vilka är_användbara vid gruskörning och dylikt, även om de rs' ~< 3 7910183-e givetvis icke har samma motstånd mot förslitning som normalkasset- tens plåtväggar.The posts 13 are suitably connected to leaves of plywood or the like, which are useful in gravel driving and the like, although of course they do not have the same resistance to wear as the sheet metal walls of the normal cassette.

Snittet enligt fig 5 visar bl a tvärbalkarnas S utseende och excenteraxelns 9 läge. Med 11 betecknas den tidigare nämnda kant- linan som håller samman alla stolpfickorna 12.The section according to Fig. 5 shows, among other things, the appearance of the crossbeams S and the position of the eccentric axis 9. 11 denotes the previously mentioned edge line which holds together all the post pockets 12.

På detta sätt erhålles en enkel möjlighet att bredda kassett~ däcket när det skall användas för styckegodskörning respektive minska dess bredd vid kassettkörníng med massgods.In this way, a simple possibility is obtained to widen the cassette deck when it is to be used for general cargo driving or to reduce its width when cassette driving with bulk goods.

Claims

. nu- 7910183-s P a t e n t k r a v

Device for trailers of the type used for driving with so-called cassette platforms, which are characterized in that they are slightly narrower than an ordinary truck platform and designed to fit inside such a platform, the device being intended to enable the platform to be adapted from carrying cassettes to become an elongated flatbed for piece goods or the like, characterized in that the cassettes (1,2) are designed in such a way that the distance between their side walls (13) can be increased to normal flat width for transport of pallet goods and the like, whereby the cassettes (1,2) - is made wider or narrower by means of at least one longitudinally torsionally rigid eccentric shaft (9), suitably one on each side of the platform, the eccentric shaft (9) being arranged to act on and extendable tubes (8) each supporting side posts (13), connected by a rigid edge line (11).

Device according to Claim 1, characterized in that two cassettes (1, 2) arranged one after the other can be interconnected in that the end pieces are folded down in the form of hatches (3), which form a load plane when driving with piece goods, the cassette walls ( 13) are designed as folding limbs, which in normal gravel driving or the like are used as walls in a normal cassette.
