Bow

from Wikipedia, the free encyclopedia
Bow on a US military towing vehicle.

Bows are substructures of tarpaulins as covers for the cargo of trucks , open-top containers (see ISO containers ) or trailers . They ensure that rainwater, for example, can run off and does not collect on the tarpaulin.

Traditionally, a bow consists of insertable, steel vertical supports with U-shaped pockets into which wooden or aluminum slats are inserted horizontally. The top stretched tightly over it is tied to the third-high side walls ("brackets") with elastic cords and locked with snap hooks .

There is also a bow for convertibles . Here it is a component of the convertible top itself, the (often wooden) connection of the convertible top to the windshield frame, to which the convertible top is locked with levers when closed.

Bows were used in body construction before the all-metal body was introduced. Because the pressing tools at that time were not big enough to form complete roof skins from five-seat and multi-seat closed structures, a wooden structure with bows was used in the roof opening. This was sealed on the outside with water-repellent material and filled with insulating material. The roof lining , which at the time was made of felt, was attached to the underside of the construction . Some car manufacturers obtained bows or the entire construction from specialized companies.
