A full perimeter vehicle frame is described having two siderails and at least one cross member having a zigzag shape which allows it to be easily removable from the siderails. The removable cross member can be square or tubular in cross section and is configured having a first end and a second end which are parallel, but offset from each other and a central portion which extends at an angle between the first end and the second end. The siderails each have an aperture which extends through the siderail from an inner side to an outer side of each siderail. One of the apertures is located at an axial position on a siderail which is offset from the other aperture located on the other siderail. These two apertures are offset the same axial distance as the amount of distancethe first and second ends of the cross member are offset from one another. In this configuration, the first end of the cross member is positioned in one of the apertures located in one of the siderails while the second end is positioned in the other aperture located in the other siderail. The cross member is easily installed by positioning one end of the cross member in an aperture in one of the siderails while the other end is positioned to lie in a plane above or below the other siderail. By laterally moving the inserted end, the free end can be rotated towards its associated siderail, and the free end of the cross member can be inserted into the aperture in that siderail. The reverse actions are taken to remove the cross member from the siderails.

Cadre périmétrique comportant deux longerons et au moins une traverse amovible en forme de zigzag pour désassemblage facile des longerons. La traverse amovible peut être de section carrée ou tubulaire; elle présente une première et une deuxième extrémités qui sont parallèles, mais déportées l'une par rapport à l'autre, et sa partie centrale forme un angle par rapport aux deux extrémités de la traverse. Chaque longeron présente une ouverture qui la traverse de part en part, de l'intérieur vers l'extérieur. Ces deux ouvertures sont déportées dans l'axe du cadre selon une distance égale à la distance de décalage entre les deux extrémités de la traverse. Cette configuration permet l'introduction des extrémités de la traverse dans l'une et l'autre ouvertures pratiquées dans les deux longerons. La traverse est facilement mise en place en positionnant une première extrémité dans l'ouverture pratiquée dans un des longerons, tandis que l'autre extrémité est positionnée au-dessus ou au-dessous de l'autre longeron. Un déplacement latéral de l'extrémité insérée dans le premier longeron permet de faire pivoter la traverse de sorte que son autre extrémité puisse être insérée dans l'ouverture pratiquée dans le deuxième longeron. Le désassemblage de la traverse est effectué en inversant l'ordre des opérations.
