Abstract
The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18′ to contact the nose cone 26′ when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.
Claims20
A unitary cordless dental drive apparatus, comprising:
- a. a foot pedal connected to an air hose for controlling a supply of pressurized air PA;
- b. an air chamber connected for receiving pressurized air PA from the air hose through the foot pedal, the air chamber formed with an inlet and an outlet;
- c. a connector mounted between the air hose and the air chamber, the connector being formed with an inlet and an outlet, the inlet being smaller in diameter than the outlet;
- d. wherein the air chamber inlet has a diameter that is similar to the connector inlet diameter, and the air chamber outlet has a diameter that is smaller than the connector outlet diameter;
- e. a wireless transmitter mounted to the air chamber, the transmitter capable of transmitting a wireless signal W corresponding to a flow of pressurized air PA from the foot pedal;
- and
- f. a wireless receiver assembled within a dental handpiece, the wireless receiver activating the dental handpiece in response to receiving the transmitted wireless signal W from transmitter;
- g. whereas the dental handpiece operating speed is related to the flow of pressurized air controlled by the foot pedal.
