Abstract

The present invention relates to a wheelbarrow having a heat-insulated tub, primarily intended for concrete, cement, mortar, etc. The problems involving premature hardening of cement during transportation in the cold are solved by the tub 4 of the wheelbarrow being configured by an outer casing 5 and an inner casing 6 of matching shape, which casings are joined together at the top edge of the tub 4 by means of a weld joint 7 and by insulating material 8 being arranged between the outer casing 5 and the inner casing 6. <IMAGE>

Description

461 640 2 fig. 1 är en schematisk vy av en skottkärra enligt uppfin- ningen, och fig. 2 är en tvärsnittsvy av den i fig. 1 visade baljan av skottkärran, och fig. 3 visar en alternativ utföringsform av uppfinningen, där skottkärran är försedd med ett lock. Fig. 1 is a schematic view of a wheelbarrow according to the invention, and Fig. 2 is a cross-sectional view of the tub of the wheelbarrow shown in Fig. 1, and Fig. 3 shows an alternative embodiment of the invention, where the wheelbarrow is fitted with a lid.

I fig.l visas en skottkärra innefattande handtag 1, stod 2, hjul 3 och en balja 4. Skottkärran är av konventionellt slag förutom baljans 4 utformning, vilket kommer att beskrivas närmare i samband med fig. 2.Fig. 1 shows a wheelbarrow comprising handle 1, stand 2, wheels 3 and a tub 4. The wheelbarrow is of a conventional type in addition to the design of the tub 4, which will be described in more detail in connection with Fig. 2.

I fig. 2 visas ett tvärsnitt av skottkärrans balja 4. Såsom framgår består baljan 4 av ett ytterhölje 5 och ett till formen av detta anpassat innerhölje 6. Ytterhöljet 5 och innerhöljet 6 består lämpligen av plåt och är sammanfogade vid baljans 4 övre runtomgående kant medelst en svetsfog 7. Mellan ytterhöljet 5 och innerhöljet 6 är ett värmeisolerande material 8 anordnat. Det värmeisolerande materialet 8 sprutas företrädesvis in i mellanrummet mellan ytterhöljet 5 och innerhöljet 6, och innefattar företrädesvis styren-polymer, t.ex. polystyren, styrenbutadiengummi. För att kondens ska kunna rinna ut från mellanrummet mellan ytterhöljet 5 och innerhöljet 6, är ytterhöljet 5 försett med dräneringshål 9 belägna i baljans understa parti. ' En alternativ utföringsform av uppfinningen visas i fig. 3. I denna utföringsform är skottkärran försedd med ett lock, som allmänt betecknas med hänvisníngssiffran 10. Locket 10 har sådan form att det passar tättslutande över baljans 4 övre kant. Locket 10 är liksom baljan 5 utformat av ett ytter- och innerhölje med däremellan anordnat värmeisolerande material.Fig. 2 shows a cross section of the tub 4 of the wheelbarrow. As can be seen, the tub 4 consists of an outer casing 5 and an inner casing 6 adapted to the shape thereof. The outer casing 5 and the inner casing 6 suitably consist of sheet metal a weld joint 7. Between the outer casing 5 and the inner casing 6 a heat-insulating material 8 is arranged. The heat insulating material 8 is preferably injected into the space between the outer casing 5 and the inner casing 6, and preferably comprises styrene polymer, e.g. polystyrene, styrene butadiene rubber. In order for condensation to flow out of the space between the outer casing 5 and the inner casing 6, the outer casing 5 is provided with drainage holes 9 located in the lower part of the tub. An alternative embodiment of the invention is shown in Fig. 3. In this embodiment the wheelbarrow is provided with a lid, which is generally indicated by the reference numeral 10. The lid 10 has such a shape that it fits snugly over the upper edge of the tub 4. The lid 10, like the tub 5, is formed by an outer and inner casing with heat-insulating material arranged therebetween.

Locket 10 kan antingen vara löstagbart från baljan 4, eller så kan det vara fäst därtill, t.ex. medelst gångjärn. 5' _ 461 640 3 Skottkärran enligt föreliggande uppfinning löser på ett enkelt sätt problemen med för tidig härdning vid. frakt av. cement, betong, bruk etc., vilket är en oundviklig nackde-l vid användning av konventionella skottkärror.The lid 10 can either be detachable from the tub 4, or it can be attached to it, e.g. by means of hinges. The wheelbarrow according to the present invention easily solves the problems of premature curing. shipping off. cement, concrete, mortar, etc., which is an inevitable disadvantage in the use of conventional wheelbarrows.
