Application April 24, 1957, Serial No. 654,824 s claims. (01.340-321) The present invention relates to safety lights, and has particular application to a self-contained unit which is adapted to be mounted on the hat of a hunter to warn other hunters of the presence of human life.
Hunting accidents frequently occur at dusk when it is ditlcult to recognize human shapes. Sometimes at the end of a day of hunting, careless hunters will shoot at anything that moves in order to avoid returning home empty handed. Therefore, at dusk, when hunters are coming from the woods, their life is in extreme danger from such careless hunters. The present invention affords a degree of safety by providing artificial light which informs the careless hunter that the movement is caused by human activity.
With the foregoing in mind, a primary object of the present invention is to provide a light mounted in a selfcontained unit which may be worn by a hunter and which operates to exhibit a flickering illumination.
More specically, the invention contemplates a light source mounted on a resilient exible support which therefore oscillates or wobbles in response to normal movement occuring upon displacement of the unit.
The invention also provides a light having the above characteristics which is highly economical to manufacture and which may also serve as a novelty attachment for youngsters and afford them some degree of protection when walking or riding bicycles at night or in dim light.
All of the objects of the present invention and the various features and details of the construction and operation thereof are more fully set forth hereinafter with reference to the accompanying drawings in which:
Fig. l is a thumb nail sketch of a safety light unit made in accordance with the present invention mounted on the cap of a hunter;
Fig. 2 is a transverse section through the unit showing the construction thereof;
Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2;
Fig. 4 is a detached perspective view of the operating components of the unit and;
Fig. 5 is an enlarged sectional view taken on the line 5-5 of Fig. 3.
In the illustrated embodiment of the present invention, the unit comprises a base member 12 which is provided with a cylindrical recess as indicated at 13 to receive an electrical assembly 14. The member 12 is provided with a plurality, in the present instance three, lugs or ears 15 at spaced intervals about its circumference. The ears are provided with fastening elements 16 for securing the member 12 to the hat. In the illustrated form of the invention, the fastening elements 16 comprise snaps which register with corresponding snaps mounted in the hat H as shown in Fig. 1. The member 12 is threaded as indicated at 18 to engage a translucent dome 19 which encloses the assembly 14 and protects the same against the weather. ln the present instance, it is contemplated that the dome 19 and the base member 12 be fabricated of a suitable plastic material which may be tinted red, frosted, or made clear.
The electrical assembly 14 of the present embodiment of the invention comprises an insulating base 22 adapted to be received in the member 12. In the present instance, the base is formed of cardboard or similar material. Mounted on the base 22 are two battery clips 23 and 24 which are adapted to receive batteries, as indicated in broken lines at B and B in Figs. 2 and 3. The battery clips 23 and 24 are formed of conductive material and are provided at one end with contact buttons 25 and 26 respectively which are insulated from the clips 23 and 24. At the opposite ends of the clips, arms 27 and 28 respectively project toward one another into closely spaced relation. A switch arm 29 is provided to electrically connect and disconnect the arms 27 and 2S 'to respectively complete and interrupt the circuit embodied in the assembly 14. In the present instance, the switch arm 29 is mounted for longitudinal movement between the position shown in full lines in Figs. 2 to 4 inclusive and the position shown in broken lines in Fig. y2. As shown, the arm has an arcuate section 31 which is operable to engage the arms 27 and 28 and eiect electrical connection therebetween. The arm is mounted for longitudinal movement by a pin 32 projecting upwardly from the insulating base 22 and passing through a slot 33 in the arm. A detent 34 is provided at the inner end of the arm 29 to engage in an aperture 35 in th-e base 22 to lock the arm in its innermost position which opens the electrical circuit. The outer extremity of the arm 29 is turned down as indicated at 36 to constitute an operation for the switch.
Means is provided to resiliently and exibly support a lamp on the base 22. To this end, an elongated helical spring element 40 is mounted on the base 22, for example by an element 41. The upper end of the spring 40 mounts a conductive strip 42 which has mounted thereon a conventional socket 43 for receiving a lamp bulb 44. The socket 43 has a conventional contact 45 ernbodied therein for contacting the center button of the bul-b 44.
Means is provided to electrically connect the socket 43 and contact 45 with the contacts 25 and 26 of the battery clips 23 and 24. To this end, a flexible conductor 46 is connected directly from the contact 45 to the contact button 26, as shown in Figs. 3 and 4. The conductor 46 is suiciently ilexible to alford free movement of the socket 43 relative to the clip 24. Electrical connection from the conta-ct button 25 to the socket housing 43 is afforded by a conductor 47 connected between the contact 25 and the clip 41. The spring 40 and the strip 42 are of electrically conductive material so as to afford current flow to energize the lamp bulb 44 when the switch arm 29 is in its full-line position.
Thus, the electrical circuit for the assembly 14 starts at the lamp 44, passes through the contact 45, the conductor 46, the contact button 26, the battery B, the clip arm 28, the switch arm 29, the clip arm 27, the battery B', the Contact button 25, the conductor 47, the element 41, the spring 40, the strip 42, and the housing 43 back to the lamp 44. The batteries B and B constitute the source of voltage for the circuit. The circuit is complete when the switch arm 29 is in its illustrated full line position, and is interrupted when the arm 29 is displaced inwardly to the broken line position shown in Fig. 2.
The flexible resilient support for the lamp 44, afforded by the spring 40 and the flexible connector 46 allow the strip 42 to move freely thereby allowing the lamp to oscillate on the spring 40. The oscillation of the lamp within the dome 19 causes a flickering or wobbling light to be apparent. when the housing is moved, as in normal walking, the lamp is caused to oscillate and present a flickering appearance.
The assembly 14 is mounted in the base member l2 by means of posts S1 and 52 projecting upwardly from the base member through apertures 53 on opposite sides of the insulating member 22. The tops of the posts 5l and 52 are peened over or fused to be enlarged and retain the assembly f4 in place in the base 12. The base 1?; is also provided with an aperture 55 which slidably receives the arm 29 and aords longitudinal movement thereof.
While a particular embodiment of the present invention has been herein illustrated and described, it is not intended to limit the invention to such a disclosure, but changes and modifications may be made therein and thereto within the scope of the following claims.
