1. Field of the Invention
The field of this invention is the construction of mobile units for the transportation of perishable food stuffs. More specifically the field of this invention is the construction of truck bodies adapted for the carring of hanging meats on tracks or rails within the body of the truck. Such tracks being adapted for releasably holding such hanging meats in a secure position within the truck. The field of this invention further embraces the means of releasing said securing means when the particular truck body is opened for the removal of such meats.
2. Description of the Prior Art
Many different prior art devices have been devised which teach various elements of the instant invention. Some of these various elements are typified by the following: U.S. Pat No. 2,590,533 by HAMER teaches generally the addition of cross beams for supporting the rails of overhead meat hanging structures thereby allowing a space between the roof and said cross beams, although it is not necessarily obvious therefrom that such space may be utilized for the storing of an overhead door. U.S. Pat. No. 3,572,815 by HACKNEY teaches the use of folding or overhead doors for truckbodies although not of the refrigerated variety and finally U.S. Pat. No. 2,827,118 by WENDT teaches insulated folding or overhead doors for refrigeration units. While these patents are typical of the prior art, there are several inherent problems left to be solved thereby. First, no means is taught showing how such hanging meats are prevented from sliding across the rails when some have been removed due to the acceleration of the carrying vehicle which still allow the hanging meats to be carried by the rails when removal is required. Further, no prior art devices allow the use of folding or overhead doors for refrigerated truck units.
It is an object of this invention to provide a truck body which allows overhead meat storage in combination with overhead doors.
It is a further object of this invention to provide a truck body wherein the hanging meats are securely held in relative position until removal is required.
