Description
AUXILIARY PORTABLE POWER SUPPLY
BACKGROUND OF THE INVENIION
Present invention relates to an auxiliary portable power supply device for use in conJunction with 05 battery-powered appliances, particularly appliances such as lightweight radios and tape playing devices.
In recent times there has been a substantial increase in the number and type of battery operated port-able devices. Ihis is particularly true of small stereo radio/tape player devlces of the type employing small lightweight headphones to facilitate use during exercise and sporting activities.
The use of such devices during exercise, jog-ging, bicycling and the like has required that the device be made as compact and as lightweight as possible, ideally so as to be attached to a belt or article of clothing without causing undue discomfort. Such size and weight limitations have therefore caused many of the devices to be designed to operate at 3 volts using two standard AA cells.
In the typical device two premium alkaline AA
cells will provide approximately 12 hours of useful oper-ating time. Attempts to design external auxiliary power sources for such devices have heretofore involved large ?5 cumbersome battery packs which often weighed as much asl or more than, the device being powered. They also con-stituted an additional unit to be separately clipped or attached to the belt or article of clothing.

SUMMARY OF THY INVENTION
The present invention provide a lightweight au~ilisry power supply ~tilizi~g a plurality of button cell, preferably of the rinc air tgpe. The present invention coDte~plsee~ a housing member containing a plurality of jells, each stapted to receive Dne or more disk shaped button cells, switch ens to oontrol the flow of o~gge~ to the cell; and electricsl connecting jeans to suitably conoect the power apply to the battery Dperated deYice or appliance.
P~EFeB~ED ~BODI~E~T
Chile the prevent invention will be described with specific reference to particular preferred e~bodiment~, it will ye understood Shat these are only two of the preferred embodi~ent~ and thy the discussion and de~criptioD ore therefore by Jay of illustration and nDt by a of limitation.
,3~3 The preferred suYili~ry portable power supply UDit comprise 8 lightweight housiDg ~d~pted to receive a plurslity of zinc 4ir type, disk shaped button cell to provide suxiliary current at 3~ and/or 6v.
Figure 1 illu~tr~te~ 8 device of the type contemplated by the prevent 05 i~vention~ generally designated as 1 attached to an appliance to be operated; shown in ~u~line only. In the embodiment illu~trat~d by figure 2, themain housLng 2 ha four vells 3, 4, 5~ and 6, etch adapted to receive fi Bingle bntton cell 13, 14, 15 and 16, a back plate 7, and a slideable svitch means 8 disposed between said back plate and the exposed l.o po6itive contact8 surface of the button c211~ 13, 14, 15 and 16, with said switch jeans 8 having 8 projecting pDrtion 18 adapted to fit within and project through aperture 28. Switch mesns 8 may be slideably roved forward or backward, by means of projectioa 18 such thst wben in the off position awitch menn~ 8 prevents air from pas~iD~ through aperture 23, 24, 25 and 26 to button cells 13, 14, 15 and 16; while when in the on position it permits air to flow through aperture to slid button cells.
Tbe unit also has connecting means 9 through which it can be electrically connected to au appliance.
As illustrated in Figure 2, the preferred ~Yitch plate 8i~ply closes off the plurality of air holes in each of the button cells.
Alternatively, the switch ean function by ~huttLng off ~oce8~ of oxygen to the iDterior of the power BUpply unit by sealing of aper-tures 23, 24, 25 and 26. This alternative ambcdiment may be less tesir~ble, in that all of the oxygen preBent in the interior of the power supply device Rt the time it is turned off till be available to the button cells wheress the preferred witch plate Gould deny any further .33 oxygen to the cells beyond that already actually inside the cell. Backplate 7 is secured in place by locking tab 17 which is adapted to pass through and releasably enqage aperture 27 in housing 2.
05 In the embodiment illustrated in Figure 2, cells 13 and 14, and cells 15 and 16, are connected in series and the two pairs of cells may be connected in parallel to produce 3 volts or in series to produce 6 volts. As shown in Figure 3, cells 13 and 14 are elec-trically connected through contact meansl9. Similar con-tact means, not shown, connect cell 15 to cell 16.
In the embodiment illustrated by Figure 4 the auxiliary power supply unit comprises a housing 32 having wells 33, 34, 35, and 36 each adapted to receive two zinc alr button cells. Back plate 7, and switch means 8 of Figure 3 are similar to back member 7 and switch means B
of Figure 2. The power supply device of Figure 4 also has electrical swltch means 3 8 sultably wired to provide power at 3 or 6 volts as desired.
Button cells 43a, 43b, 44a, 44b, 45a, 45b, 46a, and 46b of Figures 4 and 5 are similar to the zinc air button cells employed in the device of Figure 1. The respective a and b cells of each pair being connected in series so that the pair of cells in each of the wells ~5 will provide power at 3 volts. Positive contact means 37 is disposed to contact the positive can of button cells 43a and 44a, and negative contact means 3 9 is disposed to contact the negative can of button cells 43b and 44b.
Similar contact means, not shown, connect cells 45a, 45b, 46a, and 46b. the respective pairs of wells are suitably connected to switch 38 through which all four pairs of cells may be connected in parallel to provide 3 volts, or two pairs may be connected in series to each other and then in parallel to the remaining two pairs of cells, so as to provide 6 volts.
~24L~733 he preferred button cell for use in the auxil-iary portable power supply unit is a model 1200HP type zinc air cell having a typical minimum open circuit volt-age 1.45/1.35, a capacity of 2400mAh and a weight of ap-05 proximately 9.9 grams. Each cell has a maximum diameterof 30.48mm and a thickness of approximately 5.1mm.
Whereas the internal 3 volt power supply pro-vided by two premium AA alkaline cells would have a use-ful life of approximately 12 hours, the four button cells of the device illustrated by Figure 1 would provide 48 hours of useful life, and the eight cells of the device illustrated by Figure 3 would provide over 96 hours. It should be noted that the limiting current capability of zinc air cells such as those employed with the device of the present invention is determined by the cathode area.
For this reason the use of eight thln cells, as opposed to four thicker button cells, (in the embodiment illustrated in Figure 3) will provide double the current capability because the eight cells will provide double the cathode area.
he device of the present invention may be at-tached to a belt or an article of clothing, however, the thinness and light weight of the power supply unit makes it particularly suitable to be attached directly Jo the outside of the appliance which it will power. this may be done by any suitable means, but the use of Yelcro-type fastener devices is particularly advantageous.
Directly attaching the power supply unit to the appliance leaves the user with substantially a single element to be secured to his belt or clothing, the weight and thickness of the combination of appliance and auxil-iary power unit being barely noticeably larger or heavier than the appliance by itself.
