BACKGROUND OF THE INVENTION-FIELD OF APPLICATION

This invention relates to lights utilized to direct attention to emergency and/or hazardous conditions; and m particularly to such signal and warning lights which are battery powered and provided with solar cell energy collection for recharging the batteries.

BACKGROUND OF THE INVENTION-DESCRIPTION OF THE PRIOR ART

Emergency, hazardous and other conditions often requ the control of the flow of traffic around, in or near the area where the condition exists. The traffic may be pedestrian or vehicular and the reason for the control is usually to protect persons and vehicles which must pass n the area where the condition exists as well as providing warning and restricting access to such area.

Barrier tapes, such as shown and described in United States Letters Patent Number 4,844,420 granted on July 4, 1989 to N.R. Oster for "Retractable Crowd Control Barrier are sometimes utilized for such traffic control but use o this type of device at night requires that the area be otherwise illuminated. Devices such as that shown and described in United States Letters Patent Number 3,917,23 granted on November 4, 1975 to R. Fink for "Flexible Traf Barrier" provide a battery powered flashing light to draw attention to the barrier but batteries wear out and must

replaced resulting in a possibly undesired maintenance expense especially where the barrier is remotely located an must be travelled to for maintenance purposes and especiall since flashing lights have a tendency to wear out battery powered electrical supplies relatively quickly. At times more than one light source may be utilized, such as shown and described for the life jacket of United States Letters Patent Number 2,741,692 granted on August 2, 1955 to W.D. Nupp et al for "Portable Electronic Identification Light" however the more light sources the quicker the battery wear down. In addition barrier tapes and lights such as those shown and described are not suitable for use with moving vehicular traffic.

On the other hand, a device such as that shown and described in United States Letters Patent Number 4,535,331 granted on August 13, 1985 to K.L. Koenig for "Portable Traffic Warning Light" appears to be designed for use in vehicular situations. However, the relatively large number of lights and relatively large battery power supply require for this type of device reduce its relative portability and may increase battery maintenance thus reducing possible utility of this type of signal and warning device.

Devices such as those shown and described in United States Letters Patent Number 3,435,412 granted on March 25, 1969 to A.H. Bohrer, Sr. for "Traffic Control Signal" and i United States Letters Patent Number 4,042,919 granted on

August 16, 1977 to R.L. Patty for "Illuminated Sign And Hi Intensity Warning Device" are more suitable for portabilit and to be hand held. However, such devices are still battery powered and suffer from battery maintenance and replacement problems discussed for other prior art devices

Some signal and warning lights are constructed to be carried by barrier devices such as those shown and describ in United States Letters Patent Number 3,015,804 granted o January 2, 1962 to E.D. Nunn for "Combined Barricade And Flashing Signal Light" and in United States Letters Patent

Number 4,710,053 granted on December 1, 1987 to J.H. KUIP al for "Traffic Control Elements." But such devices also suffer from problems created by batteries and battery maintenance and replacement as discussed hereinabove. United States Letters Patents Numbered 4,751,622 granted on June 14, 1988 to L.E. Williams for "Solar Powe Construction Light" and 4,884,017 granted on November 28, 1989 to L.E. Williams for "Solar Powered Construction Lig seek to alleviate the battery wear down, maintenance and replacement problems of prior signal and warning lights b providing solar collectors to generate electricity to recharge the batteries. However, the inherent constructi of such signal and warning light devices limits their use those requiring attachment of the signal to a barrier because these devices are not provided with means to otherwise facilitate their portability and use separate f

a barrier. In addition, such signal and warning lights ar quite often used in locations where there is considerable dirt and dust, such as at construction sites. The collection of dirt and dust upon the surface of the solar collectors will reduce if not severely curtail, the efficiency and operation thereof and thus reduce battery life. Moreover, normal working conditions at such construction sites may subject such solar collectors and covers provided therefore to hazardous conditions which ma result in breakage of the cover and subsequent damage to a relatively expensive solar collector.

United States Letters Patent Number 4,772,990 granted on September 20, 1988 to P.M. Linehan et al for "Solar Powered Warning Flasher" shows and describes a device similar to those described above and for similar uses but one where the solar collection is by batteries which incorporate internal photo voltaic cells. This increases the price of the batteries, possibly unduly, and provides limited light collection surfaces thus limiting the abilit to collect power for storage. This type of device is also limited to use with a barrier because it is not otherwise provided with means to facilitate its ready transportability.

Solar powered battery operated and illuminated devices are also shown and described in United States Letters Paten

Number 4,977,488 granted on December 11, 1990 to J.C. Spott

et al for "Solar Powered Outdoor Recreational Light With Positionable Solar Panel" and in United States Letters Patent Number 4,989,124 granted on January 29, 1991 to T.E Shappell for "Solar Powered Sign." However, such devices ₊ 5 are not constructed for portability and do. not adequately protect their respective solar collectors from dirt, dust and possible breakage.
