Abstract

A motorcycle cruise 60 control includes a throttle 12 attached to a handlebar 15 of a motorcycle 14 that controls the motorcycle'"'"'s speed and an indexer 100 attached to the throttle. The throttle 12 is turned manually using normal torque to increase the speed of the motorcycle, and the indexer 100 has a cruise position and a neutral position. In the cruise position, the indexer 100 holds the throttle 12 in a selected position yet enables the throttle to be turned manually in a stepwise manner. A manual actuator 82 attached to the indexer 100 is used to switch manually the indexer between the cruise position and the neutral position. The throttle 12 with the indexer 100 in the neutral position is turned using essentially the normal torque, and with the indexer in the cruise position is turned using substantially greater than the normal torque.

Claims

1. A cruise control for a motorcycle having a throttle member for controlling the motorcycle'"'"'s speed attached to a handlebar of the motorcycle and adapted to be turned manually using a normal torque to increase the speed of the motorcycle, said cruise control including

a housing adapted to be attached in a fixed position to the handlebar of the motorcycle,

said housing at least partially enclosing at least one ball member, an engagement ring, a ball member retainer ring, and a detent ring,

said engagement ring, ball member retainer ring, and detent ring being concentricity aligned within the housing so that, upon attaching the housing to the handlebar, the throttle member extends through the rings and the engagement ring is seated on the throttle member to turn relative to the throttle member,

said ball member retainer ring being in a fixed position between the engagement ring and the detent ring, and said detent ring being adapted to be fixedly attached to the throttle member upon attaching the housing to the handlebar, so that said detent ring moves in unison with the throttle member,

a spring member that brings said ball member, engagement ring, ball member retainer ring, and detent ring into engagement with each other,

an actuator member extending outward from said engagement ring and the housing for manually turning said engagement ring,

at least one pair of grooves in said engagement ring, one groove being a deep groove corresponding to a neutral position and the other groove being a shallow groove corresponding to a cruise position, said ball member being seated within one of said grooves and moveable between said grooves with rotation of the engagement ring,

said ball member retainer ring having at least one opening therein that receives at least a portion of the ball member to hold the ball member so that, with the rotation of the engagement ring, the ball member moves between the grooves,

said detent ring having a series of teeth which engage a portion of the ball member, there being a lesser force of engagement between said ball member and teeth when the ball member is in the deep groove, so that essentially a normal torque repositions the throttle member, and there being a greater force of engagement between said ball member and teeth when the ball member is in the shallow groove, so that a substantially greater than normal torque repositions the throttle member and the throttle member remains in a selected position until manually repositioned using such greater torque.

2. The cruise control of claim 1 where the housing is removeably attached to the handlebar.

3. The cruise control of claim 1 where the ball member retainer ring is sized so that the engagement ring is disposed therein.

4. The cruise control of claim 1 where the engagement ring has a peripheral edge portion to which the actuator member is attached.

5. The cruise control of claim 1 where the engagement ring has a face portion in which the grooves are disposed.

6. The cruise control of claim 1 where the detent ring enables the throttle member to be turned in a stepwise manner one tooth at a time as the detent ring is turned in unison with the throttle member.

7. The cruise control of claim 1 where the ball member retainer ring has a peripheral lip portion with a passageway therein that receives the actuator member and exposes the actuator member for manual manipulation to enable the engagement ring to be manually rotated clockwise and counterclockwise and a circumferiential flange portion with at least one opening therein that receives at least a portion of the ball member so that, with the rotation of the engagement ring between the neutral position and the cruise position, the ball member moves from the deep groove to the shallow groove.

8. The motorcycle cruise control of claim 1 where said throttle member with the indexer in the neutral position being turned using essentially the normal torque, and said throttle member with the indexer in the cruise position being turned using substantially greater than the normal torque.

9. A motorcycle cruise control including

a throttle member attached to a handlebar of the motorcycle that controls the motorcycle'"'"'s speed, said throttle member being turned manually using a normal torque to increase the speed of the motorcycle, and

an indexer that is manually moveable between a cruise position and a neutral position, said indexer in the cruise position holding the throttle member in a selected position yet enabling the throttle member to be turned manually without disengaging the cruise control,

said indexer including a pair of pressure members, one of said pressure members having one pair of grooves therein, one groove being a deep groove corresponding to a neutral position and the other groove being a shallow groove corresponding to a cruise position,

a moveable member seated within one of said grooves and moveable between said grooves with rotation of one of the pressure members.

10. A motorcycle cruise control, including

a throttle member attached to a handlebar of the motorcycle that controls the motorcycle'"'"'s speed and is adapted to be turned manually using a normal torque to increase the speed of the motorcycle, and

an indexer attached to the throttle member that is manually moveable between a cruise position and a neutral position, said indexer including a plurality of pressure members mounted to the throttle member which engage each other at a first pressure when the indexer is in the neutral position and at a second pressure when the indexer is in the cruise position which is substantially greater than said first pressure,

one of said pressure members having one pair of grooves therein, one groove being a deep groove corresponding to a neutral position and the other groove being a shallow groove corresponding to a cruise position,

a moveable member seated within one of said grooves and moveable between said grooves with rotation of one of the pressure members,

said pressure members with the indexer in the neutral position enabling the throttle member be turned manually using essentially the normal torque and said pressure members with the indexer in the cruise position holding the throttle member in a selected position yet enabling the throttle member be turned manually using substantially greater than the normal torque.

11. The motorcycle cruise control of claim 10 where a pair of said pressure members form a detent assembly that provides a tactile and audible indication as the throttle member is turned.

12. The motorcycle cruise control of claim 10 where the detent assembly enables the throttle member to be turned manually in a stepwise manner.

13. A cruise control for a motorcycle, including

a throttle member for controlling the motorcycle'"'"'s speed attached to a handlebar of the motorcycle and adapted to be turned manually using a normal torque to increase the speed of the motorcycle,

an indexer attached to the throttle member that is manually moveable between a cruise position and a neutral position, said indexer including a detent assembly enabling the throttle member to be turned manually in a stepwise manner, said detent assembly including a plurality of pressure members with each pressure member having a central opening therein,

said pressure members being concentrically aligned with each other and mounted on the throttle member so that said throttle member extends through the central openings of the aligned pressure members, and

a spring member which applies pressure to the pressure members so that said pressure members engage each other at a first pressure when the indexer is in the neutral position to enable the throttle member be turned manually using essentially the normal torque and at a second pressure when the indexer is in the cruise position which is substantially greater than said first pressure to hold the throttle member in a selected position yet enabling the throttle member be turned manually using substantially greater than the normal torque.

14. The motorcycle cruise control of claim 13 where one of the pressure members has a series of teeth and the detent assembly includes a ball member that engages the teeth one tooth at a time as the throttle is turned, providing stepwise movement of the throttle member.

15. The motorcycle cruise control of claim 14 where the detent assembly provides a tactile and audible indication as the throttle member is turned.
