(c) a circuit means for transferring electrical energy from each panel to a battery; and zo (d) module interconnection means for interconnecting sirnilaz modules in electzical contact.
It has been found that hingedly connected body members afford a user with previously unrealized portability for the solar utut. As will be appreciated by those skilled in the art, any type of battery or voltaic pile wl~icl~ is rechargeable may be recharged by this system. It is also envisioned that the unit can provide power to an apparatus via a passage s of energy into a capacitor network. As mentioned herein above, a convenient advantage to this structure is seen in the enhanced durability of the solar panels- As is known, solar panels are typically quite fragile and by providing a strong plastic or other synthetic material body to support the panels, the user can use the panels for applicatxoz~s previously not possible-to The arrangement has been designed to facilitate interconnection of similar modules for applications requiring higher power. As a distinct advantage, since the units are modular a large number of 'them can be linked and disassembled wluch was not possible with the larger and move massive units in the prior art.

DETAILED DESCRIPTYO~T OF THE PREFERRED E1V~BODIMENTS
Referring now to the drawings, Figure 1 illustrates the overall structure of s the battery charger globally denoted by numeral 10. The arrangement is shop in a closed condition in Figure I and includes a pair of body members 12 and 14 each of which includes a solar cell array 16 and 18, respectively. As seen in Figure 2, each solar cell array 16 and 18 is spaced inwardly from the perimeter of its respective body member 12 or 14.
The body members 12 and 14 are interconnected by a hinge, each body io member 12 and 14 having mating sections 20 comprising the hinge. The hinge 20 includes opposed ends 22 and 24 each serving to receive an inserted male electrical contact 30 or a female electrical contact receptacle 34. It will be understood that each individual unit 10 includes one of the removable male connector 30 for interconnecting the female connectors 34. This has been found to be particularly useful for interconnection of similar modules so ~ s that the same eau be ganged to multiply the charging power of an interconnected unit, such is that shown in Figure 4 relative to the single uz~xt shown in Figure 2.
In order to ensure positive contact and prevent any inadvertent disconnection of a ganged unit, each unit 10 further includes a retractable extension 40, shown best in Figure 3 and which is adapted to extend outwardly from one of the body members 12 or 14.
2o In the example, body member 14 includes the retractable proj ectaoz~ 40 which retracts into and out of the body member 14. Extension and retraction is achieved by actuating slidable Iocks 44 which are molded into the under side of one of the body paaels. Any suitable az~rangement can be ennployed to retain the projection 40 in either its retracted position as shown in Figure 3 or the extended position (not shown). Projection 40 cooperates and is received by a mating receptacle 48 extending within one of the body members l2.or 14, rn this manner, the extension of projection 40 into receptacle or slut 48 achieves a physical bridging and locking connection between ganged unfits, for added security and strength and s therefore also alleviates any mechanical stress that would be placed on the electrical connection between interconnected units.
The underside of body mennbez~ 14, shown in Figure 3, also includes a peripheral ch.a~nnel 49 which has an open end adjacent projection 40. Tha channel 48 is associated with each edge of the body panel 14 as shown and is adapted to accommodate a substantially rectangular battery pack (not shown), slidably inserted therein.
The battery pack may be charged from the energy received by solar arrays 16 and 18 with the energy being transferred directly to the battery pack by two connection contacts on the underside of body member 14, which make wiping contact with the battery terminals as the battery is slid home along channel 49.
is The underside of panel 14 also includes a pair of support legs 60 which are hingedly connected to the body for movement outwardly of the body such that they are substantially orthogonal relative to the body member 14 in a use position, to support the body member 14, in an inclined position.
When not in use, the body members 12 and 14 can be moved from an open ao condition such as that shown in Figure 2 to a closed position, in overlying facing relation and retained in this position by a Conventional lock mechaniszu_ The male portion of the lock is denoted by numeral 64 in body member 14 and the female portion 68 is in body member 12 which receives member 64. A release button 72 is provided to disengage the connected portions 64 and 68.
As a protective mechanism, each end 22 and 24, when similar units are not connected will include protective covers 76 which prevent any debris from entering the contacts.
Turning to Figure 5, shown is a further embodiment of the present invention where additional solar arrays 16' and 18' are associated with the overall unit. The auxiliary solar arrays 16' and 18' are preferably hingedly cozyxxected at 80 by hinges (not shown) to a respective body panel 16/18. When not in use, the auxiliary panel lb~ can simply be folded ~o inwardly towards one another_ The unit is thus folded into a closed, mutually protective position, The additional ox auxiliary panels 16' and 18' can be incorporated where the voltage requirements to charge a battery are higher or the overall duty cycle of the arrangement is more strenuous.
With 'respect to the material of which the unit 10 may be made, the body ~ s membezs 12 and 14 are preferably constructed of non-electxo magnetic materials which ate also W stabilized to prevent premature degradation inherent with solar exposure. Suitable nn~aterials include high impact polystyrene, composite materials, ceramics, eu.
With respect tv the solar arrays, the individual choice of material will depend upon the voltage requirements of the battery and thus this parameter will be well ao appreciated by one skilled in the art.
It will be understood that any number of units cans be ganged together.
Although embodiments of the invention have been described above, it is not limited thereto and it will be apparent to these skilled in the axt that numerous modifications form part of the present invention insofar as they do not depart from the spirit, naturE and scope of the claxrr~ed and descabed invention.

(c) a circuit arranged to transfer electrical energy from each said panel to a battery;
(d) at least one interconnector on at least one of said body members configured to interconnect similar battery chargers in electrical contact;
(e) wherein at least one interconnector includes a third cooperative engagement member and a fourth cooperative engagement member, said fourth cooperative engagement member adapted for releasable connection with a similar third cooperative engagement member of a similar panel; and (f) wherein said third cooperative engagement member and said fourth cooperative engagement member physically link connected battery charges in a non-electrical manner.
20. The battery charger as set forth in claim 1, wherein said first body member and said second body member form at least part of a substantially rigid enclosure that encloses the solar panels in said storage position.
