Abstract
Abstract A light alloy body structure particularly for transport vehicles, including a top structure and said structures fixed along longitudinal edges of the top structure extending transverse thereto. At each of the two longitudinal edges of the top structure of the vehicle a composite longeron member is provided having a curved cross-section. The longeron member consists of two mating elongated shaped members rigidly connected to each other along longitudinally extending mating surfaces thereof and connecting the top structures with the respective side structure of the body structure of the vehicle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
201 words
A light alloy body structure having a longitudinal extension, a widthwise extension and an upward extension, particularly for transport vehicles, including a top structure having opposite composite longitudinal side edge longeron members, opposite side wall structures fixed respectively on said composite longitudinal side edge longeron members, a front wall structure and a rear wall structure, wherein said composite side edge longeron members comprise each a first and a second elongated shaped hollow box section member having each a reinforcing inner cross-piece like web, a mating longitudinal edge surface on each of said box section members facing each other and having longitudinally extending mating tongue and groove formations for rapid assembling and for rigid mutual connecting therewith, said first shaped hollow box section member having a generally arcuated cross-section with an upper and a lower portion, said upper portion extending in alignment with said top structure and being rigidly connected therewith thereby to form a rigid unit therewith, said lower portion extending in alignment with the respective side wall structure and being rigidly connected therewith thereby to form a rigid unit therewith and means for rigidly connecting said front wall structure and said rear wall structure with said opposite side wall structures.
Claim 2
Dependent Claim
201 words
A light alloy body structure having a longitudinal extension, a widthwise extension and an upward extension, particularly for transport vehicles, including a top structure having opposite composite longitudinal side edge longeron members, opposite side wall structures fixed respectively on said composite longitudinal side edge longeron members, a front wall structure and a rear wall structure, wherein said composite side edge longeron members comprise each a first and a second elongated shaped hollow box section member having each a reinforcing inner cross-piece like web, a mating longitudinal edge surface on each of said box section members facing each other and having longitudinally extending mating tongue and groove formations for rapid assembling and for rigid mutual connecting therewith, said first shaped hollow box section member having a generally arcuated cross-section with an upper and a lower portion, said upper portion extending in alignment with said top structure and being rigidly connected therewith thereby to form a rigid unit therewith, said lower portion extending in alignment with the respective side wall structure and being rigidly connected therewith thereby to form a rigid unit therewith and means for rigidly connecting said front wall structure and said rear wall structure with said opposite side wall structures.
Claim 3
Dependent Claim
112 words
A body structure according to claim 1, wherein said means for rigidly connecting said front wall structure and said rear wall structure with said opposite side wall structures respectively, comprise, at each corner defined by a side wall structure and a front wall and rear wall structures respectively, a first terminal hollow box section member upright rigidly connected with one edge portion thereof to the respective side wall structure and having a first mating surface and a second terminal hollow box section member upright rigidly connected to one among said rear wall and front wall structures respectively and having a second mating surface facing said first mating surface and rigidly connected thereto.
