Abstract

A calorie counting racket has a skeleton (10) with a hollow grip (11) and a counter unit (20) secured inside the grip (11) with multiple press buttons and a display (25) protruding from a side surface of the grip (11). The counter unit (20) has a microprocessor (21), a frequency counter (22) to record numbers of swings of the racket, a force estimating unit (23) to detect acceleration of the skeleton (10), a set of press button to control the microprocessor (21), and a display (25) to show calorie data. So that the calorie counting racket determine the burned calories immediately and precisely in accordance with different users.

Claims

1. A calorie counting racket comprising:

a skeleton (10) having a grip (11) and a frame (12); and

a counter unit (20) securable inside the grip (11) of the skeleton (10);

wherein the counter unit (20) comprising

a microprocessor (21);

a frequency counter (22) electrically communicating with the microprocessor (21) and inputting quantities of swings of the racket to the microprocessor (21);

a force estimating unit (23) electrically communicating with the microprocessor (21) and inputting acceleration of the racket to the microprocessor (21);

press buttons (24) electrically communicating with the microprocessor (21) and to refresh data of the microprocessor (21); and

a display (25) electrically communicating with the microprocessor (21) to display information from the microprocessor (21).

2. The calorie counting racket as claimed in claim 1, wherein the frequency counter is a bounce switch.

3. The calorie counting racket as claimed in claim 1, wherein the force estimating unit (23) is an acceleration sensor.

4. The calorie counting racket as claimed in claim 2, wherein the force estimating unit (23) is an acceleration sensor.

5. The calorie counting racket as claimed in claim 1, wherein the display (25) is a segment display.
