Motorcycles and motor bikes are insome instances provided vwith ignition grounding circuits controlled by handle bar mounted push button switches The push button switches presently in use generally include a switch body relative to whicha spring-biased push button is slidably supported. In addition. push button switches presently inuse must either be semipermanentlyattached to the associated handle bars by means of fasteners or clamps which inherently disfigure the handle bars and constitute protrusions on the handle bars which may cause injury to the user of the motorcycle in the event of an accident Still further, conventional push button *kill switches are subject to being clogged by mud and grit.
SUMMARY OF THE INVENTION The ignition grounding switch of this invention has been designed in a manner enabling it to be readily removably mounted on an associated handle bar without marring the handle bar in any manner. In addition, all of the ignition grounding switch, except for the grounding contact thereof, is constructed of elastomeric material which greatly reduces thechances of injury in the event of an accident and the switch of the instant invention is not readily subject to malfunction due to grit or mud.
The grounding switch includes a band-type body of elastomeric material having an opening formed through one end and an integral T-shaped extension on the other end which may be releasably secured through the opening formed in the remote end in order to secure the ends of the band-type body about an associated handle bar assembly. One side edge portion of the band includes an outwardly opening recesstin which a conductive member is seated and the conductive member projects outwardly of the recess and its outer end may be deflected from a normal position spaced slightly above the associated handle bar downwardly into electrical contact with the associated handle bar.
It is accordingly the main object of this invention to provide an extremely inexpensive grounding switch for the handle bar of a motorcycle or motor bike.
Another object of this invention is to provide a grounding switch which maybe readily attached to an associated handle bar without marring the handle bar in any manner. v v
Yet another object of this invention is to provide a grounding switch which maybe removably secured to the associated handle barwithout the use :of;tools'. I
Another important objectl of this invention is toprovide an ignition grounding switch for use on a motorcycle handle bar and constructed'ina manner whereby the switch may be maintained in adjusted position on the handle bar and yetmay be readily, shifted in position along the handle bar without the use of tools.
' A final object of this invention to be specifically enumerated herein is to provide an ignition grounding switch for the handle bar of a motorcycle which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble-free in operation.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction-and operation as more fully hereinafter described and claimed, reference being bad to the'accompanying drawings forming a' part'he reof,
wherein like numerals refer to like parts throughout.
' BRII- IF DESCRIPTION OF THE DRAWINGS 1 FIG. 1 is a fragmentary perspective view'of one end portion of a motorcycle handle bar with the ignition grounding switch of the instantinventi on mounted on the handle 'bar;
FIG. 2 is an enlarged fragmentary sectional'vie wtaken substantiallyupon the plane indicated by the section line 2-2 ofFIG'.
FIG. 3 is a sectional view taken substantially upon the plane indicated by the section line 3 -3 of FIG. 2; and
FIG. 4 is a perspective view of the 'ignition' circuit grounding switch of the instant invention prior to its being applied to an associated handle bar and electri cally connected to an associated ignition circuit.
Referring now more specifically to the drawings, the numeral 10 generally designates a motorcycle handle bar including an end portion 12 having a handgrip l4 thereon.
The ignition grounding switch of the instant invention is referred to in general by the reference numeral 14 and is mounted on the handle bar end 12 in a manner which will become apparent from the following description and FIGS. 1, 2 and 3 of the drawings.
The switch 14 includes a panel member 16 constructed of insulative elastomeric material. The panel member 16 is in the form of an elongated strap member and the opposite ends of the strap member. 16 include coacting anchor means operable to releasably secure the ends of the strap member together. The anchor means include an aperture 18 formed in one end of the strap member and an integal T-shaped extension 20 carried by the other end of the strap member.
The panel member 16 includes inner and outer side surfaces 22-and24 joined by opposite side edges 26 and 28. The panel member 16 includes a blind recess 27 formed therein which opens outwardly of the side edge 26 and a flat and substantially straight and resilient strap-type conductive member 30 has one end 32 thereof seated in the recess 27 while the other endof the conductive member 30 projects outwardly of the side edge 26 of the panel or strap member 16.
From FIG. 2 of the drawings it may be seen that the outwardly projecting end 34 of the jconductivernember 30 is normally spaced above the underlying portion of the handle bar end 12. However, it is to be noted that may bes'kdownwardly' deflected into' electrical contact with the handle' barend 12. Further, from FIG. 2'of the drawings it niay be seen vthat the panel member'16'in- I eludes an integral flap 38 whichipfojects outwardly of theside edge 26 and'ov-erlies'the' outwardly projecting end 34 of the conductive member 30. Further, the-flap 38 includes a depending abutment 40 against which the outer end 34 of the conductive member 30 is abutted. In this manner, the abutment 40 tends to retain the conductive member 30, which can be lengthwise removed from the recess 27 when the outer portion of the flap 38 is upwardly deflected, in seated position within the recess 27.
Still further, the side edge portion of the panel member 16 remote from the side portion thereof from which the conductive member 30 projects has a small diameter passage 42 formed therein. One end of the passage 42 opens outwardly through the sideedge' 28 of the panel member 16 and the inner end of the passage 42 opens into the center portion of the inner end of the recess 27. An insulated conductor wire 44 has one end thereof electrically connected to the inner end of the conductive member 30 as at 46 and the other end of the wire 44 may be electrically connected to any suitable portion of the ignition circuit of the associated motorcycle in order that the ignition circuit may be grounded whenever the flap 38 is depressed so as to depress the extended end 34 of the conductive member 30 into electrical contact with the handle bar end 12, it being understood that the handle bar end 12 constitutes a ground for the ignition circuit.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modfications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
