Abstract
A tradesworker's radio has a weather and impact resistant features to enable a tradesworker to use the radio under adverse working conditions, such as construction or other work sites. Louvered grills covering moisture resistant loudspeakers are angled downward to protect the speakers from direct splash in case the radio is left outdoors in a heavy downpour. A layer of felt-like material is interspersed between the louvered grills and the loudspeaker cones to offer improved moisture resistance. A non-telescoping antenna of the rubber covered spring type material folds neatly into recess when not in use. The controls include waterproof pushbuttons for on/off, volume adjustment, a weather channel, AM/FM selection and tuning. Elastomeric blocks are bonded to the interior of the housing and the blocks have bonded threaded studs, which are used to shock mount the radio circuit board to the inside of the housing. This circuit board is treated with a conformal coating to improve its moisture resistance. The preferred housing material is a layer of rigid plastic, which is impact resistant and the outer covering is a resilient tough elastomer. The radio can be used with an adapter to convert to a power hand tool battery pack to accommodate a variety of different battery packs and adapters. The battery compartment is generous in size and lined with a soft polyurethane material to protect the battery pack from damage.
Description
- The present invention relates to durable, rugged radios for tradesworker in construction and other worksites.
- Tradespersons working at construction sites regularly use portable radios for entertainment and to obtain weather reports. However, these radios lack certain features that would be desirable for such use. Small radios often lack the power desirable for overcoming ambient noise of other workers or to carry the sound over long distances outdoors. Although “boom boxes” may have the desired power output, they lack the ruggedness and splash proofing that is desirable. Other features, such as the convenient use of rechargeable batteries, are missing as well.
- The prior art relates to some of these shortcomings. U.S. Pat. No. 4,006,764 of Yamamoto et al. relates to a protection case that can be used to enclose a tape recorder or radio to protect it from water spray or dust without seriously impeding sound transmission. U.S. Pat. No. 4,709,201 of Schaefer et al. discloses a modular battery pack with an on/off switch and contacts arranged for various modes of operation. U.S. Pat. No. 4,225,970 of Jaramillo et al. relates to a splash proof portable two-way data terminal/radio. It describes the use of tongue-in-groove elastomeric gaskets in the housing assembly as well as air-permeable water resistant material to achieve its results.

Retractable electric cords are disclosed in U.S. Pat. No. 3,984,645 of Kresch. Moreover, portable radios are described in general in U.S. Pat. No. 4,913,318 of Forrester.
- It is an object of this invention to provide a radio with improved impact resistance.
- It is a further object to provide a radio that has a built-in retractable line cord for operation from an AC supply.

FIG. 7 is a schematic of an alternate embodiment of the radio of the present invention. -
FIG. 1 shows the tradesman'sradio 1.Housing 13 is a molded plastic structure, although alternate rugged materials such as aircraft aluminum can be used. Stainless steel louvered grills 11 cover the moisture resistant loudspeakers. Louvered grills 11 are angled downward to protect the speakers from direct splash incase radio 1 is left outdoors in a heavy downpour. - A layer of felt-like material such as described in Jaramillo et al. U.S. Pat. No. 4,225,970 can be interspersed between the
louvered grills 11 and the loudspeaker cones to offer improved moisture resistance. An example of such material which allows good sound transmission while blocking moisture is known as NB-25, manufactured by Nu-Way Speaker Products, Inc. - Non-telescoping antenna 2 is of the rubber covered spring type material; it folds neatly into
recess 3 when not in use. The controls include waterproof pushbuttons for on/off 3, volume adjustment 4 & 5,weather channel 6, AM/FM selection 7 and tuning 9 & 10. Thedigital tuning display 8 is either a self-illuminating vacuum fluorescent display or an LCD backlighted by an electro-luminescent back light panel. Both of these technologies are common in automotive radio applications.Side door 12 withpiano hinge 15 andslide latch 14 provide access to the retractable cord. A similar door (not shown) on the other side provides access to the battery compartment. Both doors are sealed watertight with appropriate gaskets. -
FIG. 2 shows backpanel 20 ofradio 1.Back panel 20 is screwed tohousing 13 withscrews 26.Slot 24 is a hand recess for carryingradio 1. Smallstainless steel louver 25 is a vent to prevent moisture buildup withinradio housing 13.Louver 25 covers an opening incover 20 that has a layer of hydrophobic air-permeable material such as Tyvek made by the DuPont Company. Other such materials of different composition are often used in medical applications; these may be used here as well. -
Waterproof button 23 turns on the battery charger;indicator 22 lights up during charging operations. Both of these are accessible throughopening 21. -
FIG. 3 shows the interior ofhousing 13 when backpanel 20 is removed. Retractableline cord housing 32 is at the left.Battery compartment 31 is at the right atopcharger housing 30. Moldedrecess 35 communicates with the hand hold slot inback cover 20. - To prevent damage to
radio 1, a plurality ofelastomeric blocks 34, such as four, are bonded to the interior ofhousing 13.Blocks 34 have bonded threaded studs which are used to shock mountradio circuit board 33.Circuit board 33 is treated with a conformal coating such as acrylic or paralyene to improve its moisture resistance. - All removable elements that penetrate or mount to
housing 13 or backpanel 20 are sealed watertight with appropriate gaskets or sealant. “Formed-in-place”gaskets 36 are shown around the back edge ofhousing 13 to sealcover 20. Anothersuch gasket 37 is shown on the surface ofcharger housing 30 to sealopening 21 inback cover 20. - The preferred housing material is a layer of ABS (acrylonitrile butadiene styrene) covered by a layer of polyurethane of approximately 50 durometers as a superbly impact resistant outer material.
FIG. 4 shows this combination in cross section where 41 is the layer of ABS and 40 is the layer of polyurethane. Other combinations are also applicable as long as the rigid plastic is quite impact resistant and the outer covering is a resilient tough elastomer. - Modern battery operated professional power tools use battery packs ranging from 9.6 to 18 volts. By selecting a 12 volt battery pack for the
radio 1, an automotive AM/FM radio circuit board and display (augmented with a weather receiver) can be used with little modification. These come with powerful audio amplifier output stages and digital lighted displays. It is desirable to use a battery pack that is also used in other tools owned by the tradesman, or is at least the same brand. However, battery packs from different manufacturers, even of the same voltage ratings, have different contact configurations. For example, the Porter Cable 8500 battery pack is different from the DeWalt DW9071 even though both have similar ratings. For this purpose,FIG. 5 shows the arrangement using astandard socket 45 attached to theradio 1, with areplaceable adapter 46 which mates properly with bothsocket 45 at one end and a particular 12volt battery pack 48 with itscontacts 49. A variety of theseadapters 46 are available for use. -
FIG. 6 shows a schematic block diagram of the electrical system. A combination power supply andbattery charger 30 is supplied with 115 VAC viaplug 51 andretractable cord 50. It supplies approximately 13.6 volts throughsilicon diode 56 to the radioelectronics circuit board 33 through on/offswitch 3. Whenbutton 23 is engaged, appropriate charge voltage is supplied tobattery pack 48 through diode 55.Diode 54 feeds current frombattery 48 tocircuit 33 in the event thatmodule 30 is not plugged into an outlet. The three diodes (54,55 and 56) act as an automatic steering and isolation network to supply AC supplied current to operateradio 1, battery power to theradio 1, or to simultaneously power and charge the batteries from AC. In all cases, a nominal 12 volts (i.e. 12 to 13.2 volts), is supplied toradio circuit board 33, which powersloudspeakers - In an alternate embodiment, additional circuitry is provided to permit the use of battery packs lower or higher than 12 volts to be used in
radio 1. In this embodiment,socket 45 is replaced withsocket 70 which now has six contacts mating with adapter 61, which match the requirements of aparticular battery pack 60. The on/off switch is now upgraded to a double pole single throw variety for controlling output DC/DC converter 68 for battery operation ofradio 1. This extra pair of contacts eliminate the “standby” losses ofconverter 68 whenradio 1 is turned off. - Charging DC/
DC converter 69 is selected viarelay 70 when the charger is turned on. Althoughelectromagnetic relay 70 is shown, a solid state relay can be used instead. Ifbattery pack 60 has a voltage rating higher than 12 volts (e.g. 18 volts), theoutput converter 68 is a step down type reducing the battery voltage to a nominal 12 volts whilecharge converter 69 is a step up converting a nominal 12 volts from the charger to a nominal 18 volts at the battery. If the battery voltage were lower than 12 volts (e.g. 9.6 volts), theoutput converter 68 is a step up type while the chargingconverter 69 is a step down type.Diodes diodes - To accommodate a variety of different battery packs and adapters, the battery compartment is generously oversize and lined with a soft polyurethane material to protect the battery pack from damage.
- It is further known that other modifications may be made to the rugged tradesworker's radio of the present invention, without departing from the scope of the invention, as noted in the appended claims.
