Speed control assembly
View Patent ↗A mower including a handle assembly and a grip coupled to the handle assembly. The handle assembly includes a cross member. The grip is moveable longitudinally relative to the cross member. The mower also includes a sensor operable to generate an output signal based on a position of the grip relative to the cross member, and a drive assembly configured to operate based on the output signal.
1. A mower comprising:
a handle assembly including a cross member;
a grip coupled to the handle assembly, the grip moveable longitudinally relative to the cross member;
a sensor operable to generate an output signal based on a position of the grip relative to the cross member; and
a drive assembly configured to operate based on the output signal.
2. The mower of claim 1 , further comprising a controller configured to receive the output signal and control the drive assembly based on the output signal.
3. The mower of claim 1 , wherein the sensor is at least one selected from a group consisting of a pressure sensor and a force-sensitive sensor.
4. The mower of claim 1 , wherein the grip includes a gripping portion, a first grip leg, and a second grip leg.
5. The mower of claim 4 , wherein the first grip leg and the second grip leg are received by the handle assembly.
6. The mower of claim 1 , wherein the cross member is parallel to the grip.
7. The mower of claim 1 , wherein the output signal is proportional to a magnitude of displacement of the grip relative to the cross member.
8. The mower of claim 1 , wherein the sensor is a transducer.
9. The mower of claim 1 , further comprising a wheel coupled to the drive assembly, wherein the drive assembly drives the wheel.
10. The mower of claim 1 , wherein the drive assembly includes an electric motor.
11. The mower of claim 1 , wherein a first portion of the sensor is coupled to the grip and moves with the grip as the grip moves relative to the handle assembly; and wherein a second portion of the sensor is fixed with respect to the handle assembly.
12. The mower of claim 1 , wherein the grip translates along a longitudinal axis of the handle assembly.
13. The mower of claim 1 , further comprising a biasing member positioned between the grip and the handle assembly.
14. The mower of claim 1 , further comprising a cutting element rotationally supported on a mower deck.
15. A mower comprising:
a first upper arm;
a second upper arm;
a cross member extending transversely between the first upper arm and the second upper arm;
a first housing coupled to the cross member and the first upper arm;
a second housing coupled to the cross member and the second upper arm;
a grip including
a first grip leg at least partially received within the first housing, and
a second grip leg at least partially received within the second housing,
wherein the grip is movable relative to the first and second housings;
a sensor configured to generate an output signal based on a position of the grip with respect to the cross member; and
a drive assembly configured to operate based on the output signal.
16. The mower of claim 15 , wherein the sensor is a force-sensitive sensor operable to measure an amount of force applied to the grip by a user.
17. The mower of claim 15 , further comprising a lower arm pivotally coupled to a bracket attached to a deck of the mower and wherein a lower end of at least one selected from a group consisting of the first the upper arm and the second upper arm is telescopically received by an upper end of the lower arm.
18. The mower of claim 15 , wherein the grip translates along a longitudinal axis defined by at least one selected from a group consisting of the first the upper arm and the second upper arm.
19. The mower of claim 15 , further comprising a biasing member biasing the grip, wherein the biasing member is at least partially positioned within the housing.
20. The mower of claim 15 , further comprising a controller configured to receive the output signal and control the drive assembly based on the output signal.
