Claim:
A mobile vehicle having a compartment within which is an installation which comprises: (a) a frame part having: (i) first and second rigid, substantially L-shaped, frame side members respectively contained in laterally spaced parallel planes; (ii) a frame first cross-member which bridges first corresponding limb portions, of said side members (iii) a frame second cross-member which bridges second corresponding limb portions of said side members; (b) means for securing said frame rigidly with respect to the vehicle body; (c) a front wall panel member hingedly connected to said frame first cross-member; (d) first and second side wall panel members respectively hingedly connected to said front wall panel member substantially at the edges thereof; (e) a lid panel member hingedly connected to said second limb portions of said frame side wall members; and in which, (f) parts (a)-(e) are constructed, arranged and adapted such that the front and side wall panel members are respectively pivotal between a first configuration in which said front and side wall panel members are in a compact relationship and a second configuration in which they are fully erect; (g) said lid panel member is pivotal about the hinge axis defined by its hinge connections with said second limb portions of said frame side members so as, with said front wall panel and side wall panel members in the erect configuration, to effect closure of an uncapped volume defined by said upstanding front and side wall panel members, thereby to constitute a security chamber; and, (h) said lid panel member incorporates means operative, with said lid panel member serving as the closure member for said uncapped volume, to lock the side wall panel members against movement about their hinge connections with the front wall panel member.
