Abstract
A weight training equipment with an ultrasonic sensor assembly including a transmitter unit, a receiver unit, a case and the support. The case is rotatably supported upon the support to expose the transmitter and the receiver upwardly. A freely rotatable pin unit is selectively inserted into the hole of the corresponding weight block of the weight training equipment to have its reflection surface downwardly face the sensor assembly. A distance between the pin unit and the sensor assembly during exercise can be measure by ultrasound transmitted from the transmitter unit toward the pin unit and further reflected by the reflection surface and received by the receiver unit.
Claims12
A weight training equipment comprising:
- a frame with a plurality of weight blocks thereon, each weight block forming a hole;
- an ultrasonic sensor assembly including a case enclosing a transmitter unit and a receiver unit facing upwardly;
- a rotatable pin unit including an upper insertion section and a lower reflection section freely rotatable relative to the upper insertion section;
- wherein
- the upper insertion section has a pin configuration and is selectively inserted into the hole of the corresponding weight block to have the reflection surface automatically arranged, via free rotation of the lower reflection section of the rotatable pin unit due to gravity thereof, in a balanced correct horizontal manner to allow the transmitter unit and the receiver unit to face the reflection section in a perpendicular manner.
A method of measuring exercising effect for weight training, comprising:
- providing a weight training equipment with a plurality of weight blocks, an ultrasonic sensor assembly and a rotatable pin unit wherein the ultrasonic sensor assembly includes a transmitter unit and a receiver unit, and the pin unit includes a reflection surface;
- positioning the ultrasonic sensor assembly under the pin unit;
- selectively inserting the pin unit into a selected weight block to have the reflection surface correctly downwardly face the ultrasonic sensor assembly by free rotation of the reflection section of said pin unit due to gravity thereof relative to the selected weight block.
