Claims20
For a self-propelled floor preparation machine, an ergonomic controller comprising:
- a. mount comprising a first handle and a hub defining a first axis of rotation;
- b. a joint having a first member coupled to a machine, a second member coupled to the mount, a pivot member adapted to permit the second member to pivot relative to the first member, and a first lock, wherein the first lock is adapted to be released to permit the second member and the mount to be pivoted relative to the first member and the machine, and wherein the first lock is further adapted to be engaged to selectively fix the second member and mount in place in a selected position relative to the first member and the machine;
- and
- c. a control stick mounted to and extending from the hub and adapted to be rotated about the first axis of rotation.

A self-propelled floor preparation machine comprising:
- a. a steerable drive wheel driven by a first electric motor;
- and
- b. an ergonomic controller comprising:
- i. mount comprising a first handle and a hub defining a first axis of rotation;
- ii. a joint having a first member coupled to a machine, a second member coupled to the mount, a pivot member adapted to permit the second member to pivot relative to the first member, and a first lock, wherein the first lock is adapted to be released to permit the second member and the mount to be pivoted relative to the first member and the machine, and wherein the first lock is further adapted to be engaged to selectively fix the second member and mount in place in a selected position relative to the first member and the machine;
- iii. a control stick mounted to and extending from the hub and adapted to be rotated about the first axis of rotation;
- and
- iv. an adjustable mounting bar coupling the first member of the joint to the machine,
- said adjustable mounting bar comprising two sections that are adapted to telescope with respect to each other to adjust the length of the adjustable mounting bar and a second lock adapted to secure the two sections together so that the adjustable mounting bar is fixed at a selected length.
