## Background
This application is a continuation of PCT/GB02/01475 filed Mar. 28, 2002.


BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to secure storage chambers for fixed installation within a compartment of a mobile vehicle, to kits of parts from which such storage chambers may be assembled, and to mobile vehicles having a vehicle compartment within which such a storage chamber shall have been installed.
The theft of valuable work tools, both mechanical and electro-mechanical, as well as other valuable items of substantial size, from mobile vehicles, notably motor vans, is commonplace, and it is the purpose of the present invention to offer a design for a secure storage chamber, being a chamber of a construction eminently well suited for installation, primarily, within a commodity carrying compartment of a van or other road vehicle.

DESCRIPTION OF THE INVENTION
The installation has a panel supporting frame (FIG. 7) which comprises: a frame part 11 having first and second rigid, substantially L-shaped, square cross-section, mild steel, tubular side members 13, 15, suitably of 2.5 mm wall thickness, said side members being respectively contained in spaced parallel planes; a frame first cross-member 17 which bridges corresponding first limb portions 19, 21, respectively, of the L-shaped side members 13, 15 at the forward ends thereof; and, a frame second cross-member 23 which bridges corresponding second limb portions 25, 27 or the L-shaped frame side members 13, 15 at the upper ends thereof.
The first limb portions 19, 21, and the first cross-member 17 of the frame, ate provided with a multiplicity of lugs 29 having passages adapted to receive bolt connectors (not shown) by means of which the installation, of which the frame 11 is part, is to be secured to the floor (not illustrated) of the vehicle compartment 31 (FIG. 1). When so secured, the first limb portions 19, 21, of the frame side members, and frame first cross-member 17 are contained in a horizontal plane, and the second limb portions 25, 27, of said frame side members, and the frame second cross-member 23 are contained in a vertical plane.
Attached to the frame 11, there are, in the example, four panel members. Each of the aforesaid panel members comprises a body of flat sheet mild-steel, suitably of 2.5 mm gauge, and an endless mild-steel tubular sub-frame of square cross-section identical to that of the side frame members 13, 15, each sub-frame being of a size and shape such as to extend round the periphery of the body of sheet material, the sub-frame and the body being secured together by tack welds at intervals around the sub-frame.
One of the four panel members is a front panel member 33 the bottom member of whose box-section sub-frame is connected by spaced apart hinges 35 to the frame box-section first cross-member 17, the hinges being such as to constrain the front panel member 33 for angular displacement between a first, or collapsed, position (FIG. 2) at which the front panel member lies flat parallel with the compartment floor, and a second, or erect, position (FIGS. 3, 4, and 5), at which the panel member 33 extends, transversely of the vehicle, upright with respect to the compartment floor. The sub-frame of the front panel member has, at its extremities, upstanding posts, as 37.
First and second side panel members 39, 41, have their sub-frames respectively connected, at hinges, as 43, to the sub-frame of the front panel member 33 adjacent to the side edges 45, 47, thereof.
It will be observed (FIG. 2), with the front panel member 33 in the collapsed state, the side panel members 39, 41, are such as each to lie with one major surface thereof in face to face contact with the compartment floor, and with the other in supporting face to face contact with the front panel member 33.
Projecting from corresponding major surfaces of the side panels 39, 41, there are two posts (not shown) each provided with a diametral hole towards the free and thereof, and the front panel 33 has two passages, as 33′, at spaced locations such that with the front and side panel members in the collapsed position shown in FIG. 2, the aforesaid posts are respectively received within said passages 33′, the free ends of the posts projecting proud of the front surface of the front panel 33. Elongate wire clips (not shown) extend through the passages, the side and front panel members being thereby held for movement as one.
In swinging the front panel member 33 upwardly from the collapsed to the erect position, the aide panel members 39, 41, are compelled to follow. The second limb portions 25, 27, of the frame side members 13, 15, have inwardly extending transversely aligned lugs 49, 51, respectively, through which correspondingly located passages, as 53, extend, and the sub-frames of the side panel members 39, 41, carry posts, as 55, the positions of which are such as, when the front panel member 33 is in the upright position, to be able, respectively, to enter the passages 53, the second limb portions 27, 29, of the frame side members 13, 15, thereby serving in the provision of rigid support for the hingedly connected front 33 and side panel members 39, 41.
The fourth panel member is constituted by the lid 57. The lid 57 spans the space between the vertical, second limb portions 25, 27, of the frame side members 13, 15, being supported therebetween for angular displacement about a transverse axis X - - - X defined by transversely aligned first and second pivotal bearing arrangements, as 59.
The lid 57 is angularly displaceable about the axis X - - - X between the vertical plane (FIGS. 2 to 5) and the horizontal plane (FIG. 6). Projecting outwardly from the underside 61 of the lid 57 at or adjacent to the side edges thereof, there are first and second lugs 63, 65, respectively, and, projecting from the outer extremities of the upper edge of the lid panel 57, there are apertured lugs 67, 69, respectively.
At the ends of the second cross-member 23, bridging the frame side members 13, 15, there are elbow extension portions, as 71, from which project apertured lugs, as 73, these providing locations at which the second limb portions 25, 27, of the side members 13, 15, of the frame 11 may be secured, at the top, to side walls or other convenient structural parts of the vehicle compartment. Other features which should be mentioned are the lid handle 75, latch means 77 for releasibly holding the lid 57 in the vertical plane, and a strong pad-locking means 79 which is for releasibly coupling the lid 57 and the front panel member 33 and which, in addition, serves as a handle for raising the front and side panel members as one from the collapsed position of FIG. 2.
It should be noted, also, that the installation is, in the embodiment, devoid of a rear panel member. The lack of such a panel member arises from the circumstance that, in the example, the frame abuts a bulkhead or analogous wall separating the driver compartment from the compartment in which the frame 11 and the several said panel members are to be found. It will be noted, also, that, in the example, the front and side panel members have cut-away portions, this to accommodate the protrusion created by the rear 79 of the vehicle engine housing.
In other circumstances, of course, a rear panel member might be provided, the latter panel member comprising, in distinction from the front, side and lid panel members, a body of mid-steel sheet material secured, directly, as by tack welds (the rear panel member not being angularly displaceable a panel sub-frame would not then b required), to the forward faces of the second limb portions 25, 27, of the frame side members 13, 15. The absence of an engine housing protrusion, as 81, would, of course, avoid the need for cut-aways in the front and side panel members.
The several Figures clearly show the conversion of the structure from a compact form (FIG. 2) to the fully erect state (FIGS. 3 to 5) at which a safe storage chamber emerges.
From the collapsed position (FIG. 2), the front 33 and side panel members 39, 41, are to be swung upwardly about the hinge axis of the front panel member. With the front panel member 33 in the vertical plane (FIG. 3), the side panel members 39, 41, may be swung outwardly about their parallel hinge axes with the front and side panel members given support by the inter-engagement between the posts 55 and lugs 49.
With the front and side panel members thus supported, the lid panel member 57 is, after being freed from the frame 11, by release of the latch means 77, for angular movement about its pivot axis X - - - X, brought to contact with the upper rims of the front 33 and side panel members 39, 41, thereby to serve as the upper closure member of the chamber so formed with the posts 37 received within the apertures of the lid panel lugs 67, 69.
As indicated within the cut-away of FIG. 5, in the course of bringing the lid panel 57 to the closure position, the lugs 63, 65, projecting from its underside, are brought to positions respectively lying in the paths of angular displacement of the side panel members 39, 41. With the chamber closed, and with the chamber pad-locked, the presence of the lugs 63, 65, secures the chamber against easy unauthorised access to valuables which may be held within the chamber, whilst, by folding the several hinged panel members to the positions shown in FIG. 2, the front and side panel members being then flat with respect to the compartment floor, and the lid panel member being supported vertically against the frame 11, the installation is unobtrusive and does not constitute an obstruction in the use of the compartment for work purposes.
It is to be observed that the elbow extension portions 69, 71, project upwardly from the cross-member 23, the frame 11 being thereby provided with a step formation, which may be used to receive one end of lengthy items, such, for example, as a ladder to be transported.
Although not illustrated, the compartment may be provided with a second frame located at the opposite end of the compartment from the frame 11 of the aforedescribed installation. The additional frame would be hinged at its lower end to be displaceable between an erect lockable position and a position at which it is in contact with the compartment floor. The additional frame, when erect, would then serve to support the ladder or other lengthy item at its rear end.
