Abstract

Abstract Safety equipment is herein described for usage by rescue workers, traffic policemen and the like. The equipment includes a piece of head gear which may comprise a conventional hard hat having a continuous, horizontally extending brim disposed thereabout. The brim may be formed with bubble-like recesses opening downwardly toward the user of the head gear. White light sources may be operatively mounted within each bubble-like recess and so disposed with respect thereto that light is directed downwardly upon the user of the head gear but, is shielded from other parties having a line of vision extending generally horizontally or downwardly toward the head gear. A second light source may be operatively mounted on top of the head gear and provided with a red lens for indicating ''''danger.'''' Electrical conductors may be provided to extend between a disconnectable source of electrical power and the various lights provided on the head gear. A transistorized flasher component may be connected within the circuitry, presented by the electrical conductors, and may be disposed on a negative side of the second light source in order to permit proper flashing thereof while minimizing interference with the remaining steady light sources. The light source on top of the hard hat may be supported by means of a tubular bolt member extending to a base portion of the light source through an aperture formed in an upper surface of the head gear. The conductors extending between that light source and the source of electromotive power may be extended through the cylindrical space defined by the tubular bolt. A clamping member may be actuated by tightening down a nut member on the tubular bolt to clampingly engage the transistorized flasher member between the clamping member and an interior surface of the hard hat.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 260 words
Safety equipment including head gear for rescue workers, traffic policemen, and the like, having a generally horizontally extending brim, said brim being formed with at least one bubblerecess disposed to open downwardly, said brim being sufficiently rigid and said recess being of sufficient depth to support at least one light source under said brim in the space defined by said recess whereby light emanating from said light source is directed downwardly on an individual properly wearing said head gear but is shielded by said brim from direct observation by other parties having a line of vision extending generally horizontally and downwardly toward said head gear, a source of electrical power connectable with said at least one light source, 2 second light source connected with said source of electrical power and mounted on a top surface of said head gear, a circuit interrupting flasher means operatively connected to said second light source whereby said second light may be intermittently actuated while said first light source is operable to generate a constant steady glow to illumiNate the individual wearing said head gear, said second light source being mounted on said head gear by a tubular threaded fastening means, a clamping member supported by said tubular fastening means and operable to clamp said flasher means against an inside surface of said head gear upon the tightening of a nut on said threaded tubular fastening means and electrical conductor means connecting said second light source to said source of electrical power and extending through an axial space defined by said tubular threaded fastening means.
Claim 2
Dependent Claim 260 words
Safety equipment including head gear for rescue workers, traffic policemen, and the like, having a generally horizontally extending brim, said brim being formed with at least one bubblerecess disposed to open downwardly, said brim being sufficiently rigid and said recess being of sufficient depth to support at least one light source under said brim in the space defined by said recess whereby light emanating from said light source is directed downwardly on an individual properly wearing said head gear but is shielded by said brim from direct observation by other parties having a line of vision extending generally horizontally and downwardly toward said head gear, a source of electrical power connectable with said at least one light source, 2 second light source connected with said source of electrical power and mounted on a top surface of said head gear, a circuit interrupting flasher means operatively connected to said second light source whereby said second light may be intermittently actuated while said first light source is operable to generate a constant steady glow to illumiNate the individual wearing said head gear, said second light source being mounted on said head gear by a tubular threaded fastening means, a clamping member supported by said tubular fastening means and operable to clamp said flasher means against an inside surface of said head gear upon the tightening of a nut on said threaded tubular fastening means and electrical conductor means connecting said second light source to said source of electrical power and extending through an axial space defined by said tubular threaded fastening means.
Claim 3
Dependent Claim 39 words
Equipment according to claim 1 wherein said source of electrical power consists of a battery retained within a casing having 2 clip member extending therefrom for supporting engagement with a belt worn by the individual using said head gear.
Claim 4
Dependent Claim 28 words
Equipment according to claim 1 wherein said casing is provided with switching means for controlling the supply of electrical power to said first and said second light sources.
Claim 5
Dependent Claim 31 words
Equipment according to claim 1 wherein said casing is further provided with a female electrical receptacle means operable to receive a male electrical connector operatively attached to said electrical conductor means.
Claim 6
Dependent Claim 34 words
The equipment of claim 1, wherein an electrical conductor means connects said second light source with said source of electrical power, and extends through and axial space defined by said tubular threaded fastening means.
