BRIEF SUMMARY
FIELD OF INVENTION

The invention relates to cabinet-structure type supports and, more particularly, to such supports having plural closures, e.g., auxiliary closure within closure.


BACKGROUND OF THE INVENTION

It is not uncommon for industrial equipment to be mounted in out-of-door cabinets or housings exposed to the weather and, particularly, to occasional vandalism. While ways to configure equipment housings to resist weather are well-known, not a great deal of attention has been given to configuring housings to resist vandalism. This is an important consideration since the housing may contain equipment, e.g., communication or other electrical equipment, important or even critical to users connected thereto.
Switch cabinets are often assembled on a pedestal with an air conditioner fastened to the roof of the switch cabinet. It is also known that smaller cabinet units can be arranged and connected one on top of the other.
A disadvantage of such known cabinets is that access to the cabinet interior can often be gained by forcing open or tearing or piercing a cabinet door or static panel. A housing assembly which addresses this disadvantage would be an important advancement in the art.


OBJECTS OF THE INVENTION

An object of the invention is to provide a modular housing assembly that overcomes some of the shortcomings of the prior art.
Another object of the invention is to provide a modular housing assembly that offers considerably improved protection against vandalism. How these and other objects are accomplished will become apparent from the following descriptions and from the drawings.


SUMMARY OF THE INVENTION

The invention involves a modular housing assembly comprised of a base cabinet body having five wall elements, a pedestal, one or more ground housings and a roof housing. Additional protective "overlay-type" lateral walls extend along part or all of the height of the assembled housing. A double-walled door closes and locks at least the base cabinet body.
According to the invention, at least the base cabinet body is secured on all sides by two respective walls so that entry into its inner space is made considerably more difficult. The lateral protective walls (which are actually exterior walls overlaying parallel interior walls) lend the visual impression of a conventional assembly. This so since the lateral protective walls extend over and cover or "mask" the joints where individual modular units of the housing assembly are joined together. In order to gain entry to the inner space of the base cabinet body, the ground housing or the roof housing, two respective walls, e.g., sheet metal walls, must be penetrated or otherwise defeated. This structure represents considerably improved protection against vandalism for housings that are set up outside.
According to one embodiment of the invention, instead of the double-panel wall element serving as the rear wall of the base cabinet body, one or more wall air conditioners are connected to the base cabinet body so that the components in the base cabinet body can be cooled. The air conditioners are, themselves, double-walled and serve to completely close that area otherwise closed by the rear wall.
In another aspect of the invention, the housing assembly includes one or more ground housings beneath the base cabinet body. In a more specific embodiment, a single ground housing is configured as a battery receptacle, thereby equipping the assembly with a source of standby emergency power. Most preferably, access to the batteries is by a ground housing fitted with a pull-out drawer.
In yet another configuration, the housing assembly includes a frame-like pedestal interposed between and connected to both the base cabinet body (the main compartment for equipment confined in the assembly) and to the single or plural ground housings, as the case may be. To state it another way, the pedestal is mounted to "subdivide" the base cabinet body from the ground housing(s).
In a variation of such configuration, the single or plural ground housings are interposed betwee
