Abstract

The systems shut-down handle for motorized apparatus comprises the housing; a throttle assembly having a pivotally mounted handle lever juxtapositioned about the grip of a handlebar of the apparatus, the throttle lever being connected to the apparatus throttle cable; and a brake and shut-down assembly having a brake lever pivotally mounted to the housing about the grip and is disengaged when the lever is depressed adjacentely about the handlebar grip and engages the brake when the lever is released and pivoted away from the grip. The lever is provided with means for actuating a cut-off switch which may break the electrical circuit controlling ignition in the engine. The brake and shutdown assembly may further include an idling trigger which may retain the brake lever adjacent the grip to disengage the brake and maintain the engine circuit.

Claims

1. A systems shut-down handle for motorized apparatus having a throttle cable, a brake operator, and an electrical circuit controlling ignition, comprising:

A housing mounted to handlebars of said apparatus;

A throttle assembly including a pivotally mounted lever juxtapositioned over the grip of said handlebar to said housing, and being connected to its end adjacent said housing to the apparatus throttle cable; and

A shut-down assembly having a brake lever connected to the brake operator pivotally mounted over said handlebar grip opposite and opposingly to said throttle lever and being provided with means for actuating a cutoff switch having means to brake the electrical circuit controlling ignition in the apparatus engine when said brake lever is released.

2. The apparatus of claim 1 wherein said brake lever of said shut-down assembly is connected at its end adjacent said housing to said brake operator which includes a cable connecting said systems shut-down handle with the brake system of said motorized apparatus.

3. The apparatus of claim 2 wherein said shut-down assembly includes means which '"'"''"'"''"'"''"'"'push'"'"''"'"''"'"''"'"' said brake control cable comprising a clevis fastened substantially perpendicularly to the end adjacent said housing of said lever, said brake control cable being fastened to the outer terminal end of said clevis.

4. The apparatus of claim 1 wherein said shut-down assembly includes means which '"'"''"'"''"'"''"'"'pull'"'"''"'"''"'"''"'"' on the brake control cable comprising a half-rod pivotally mounted at its center and fastened at one of its terminal ends to said brake lever by A linkage and at its end opposite to said brake control cable, said half-rod being mounted to pivot from a diagonal line in said housing wherein the terminal end fastened to said brake lever linkage is disposed away from said brake lever and the end connected to said brake control cable is disposed distally vertically adjacent said brake lever to a vertical orientation.

5. The apparatus of claim 1 including an idling trigger having means for selectively retaining said brake lever adjacent said grip.

6. The apparatus of claim 4 wherein said idling trigger includes a lever arm portion pivotally mounted in said housing distally from a pivot point of said brake lever and said housing in the direction opposite said housing with the end adjacent said grip said lever arm projecting from said housing above said brake lever, said lever arm having a shoulder portion on its side adjacent to said brake lever, the terminal end adjacent said pivot of said brake lever and said housing being provided with a slot being selectively engageable with said shoulder of said lever arm.

7. The apparatus of claim 6 wherein said lever arm is provided with a coil spring urging said lever arm away from said grip and said brake lever, and a finger portion disposed from the terminal end of said arm portion adjacent said brake lever.

8. The apparatus of claim 1 wherein said cut-off switch is a reverse push button connected into the electric circuit controlling ignition in the motor of said apparatus.

9. The apparatus of claim 1 wherein said cut-off switch is provided with an override switch having means to maintain operation of said engine with said brake lever is released, said means being engageable by a separate manual act.

10. The apparatus of claim 9 wherein said override switch is a press button toggle switch mounted in said housing, and being electrically connected in parallel to wires connecting said cut-off switch to said ignition circuit.
