Exercising hula-hoop assembly with radio frequency signal transmission and receiver unit

Abstract

An exercising hula-hoop assembly with a radio frequency signal transmitter and a remote receiver unit includes an exercising hula-hoop, at least one depressible switch arranged on the interior surface of the exercising hula-hoop, a switch contact assembly arranged within the inner space of the exercising hula-hoop. The switch contact assembly is operable by the depressible switch, so that a triggering signal is generated each time the triggering switch is depressed. The radio frequency signal transmitter generates a radio frequency signal when receiving a triggering signal from the switch contact assembly. The remote receiver unit receives the radio frequency signal transmitted from the radio frequency signal transmitter for counting and displaying.

What is claimed is:  
     
         1 . An exercising hula-hoop assembly, comprising: 
 an exercising hula-hoop having an interior surface and an opposite exterior surface defining an inner space therebetween;    at least one depressible switch arranged on the interior surface of the exercising hula-hoop;    a switch contact assembly arranged within the inner space of the exercising hula-hoop, operable by the depressible switch, which generating a triggering signal each time the triggering switch is depressed;    a radio frequency signal transmitter arranged with in the inner space of the exercising hula-hoop and electrically connected to the switch contact assembly, for generating a radio frequency signal when the triggering signal is received from the switch contact assembly; and    a remote receiver unit with a radio frequency signal receiving circuit for receiving the radio frequency signal transmitted from the radio frequency signal transmitter.    
     
     
         2 . The exercising hula-hoop assembly as recited in  claim 1 , wherein the exercising hula-hoop comprising a plurality of arched sections and a plurality of connecting rings coupled therebetween, at least one of the arched sections being mounted with the depressible switch, the switch contact assembly, and the radio frequency signal transmitter.  
     
     
         3 . The exercising hula-hoop assembly as recited in  claim 1 , wherein the switch contact assembly comprises: 
 a pair of separated contact pads electrically connected to the radio frequency signal transmitter and fixedly located within the inner space of the exercising hula-hoop; and    a contact plate made of metal material arranged in the inner space and moveable by the depressible switch, facing the contact pads with a distance; when the depressible switch is depressed by a force applied from the interior surface of the exercising hula-hoop, the contact plate is moved toward and contact the contact pads.    
     
     
         4 . The exercising hula-hoop assembly as recited in  claim 3 , further comprising at least one elastic member inserted between the depressible switch and the interior surface of the exercising hula-hoop.  
     
     
         5 . The exercising hula-hoop assembly as recited in  claim 1 , wherein the radio frequency signal transmitter comprises: 
 an encoder for receiving the triggering signal generated by the switch contact assembly and supplying an encoded triggering signal;    a frequency modulator for receiving the encoded triggering signal supplied by the encoder and supplying a modulated signal; and    an amplifier for receiving the modulated signal supplied by the frequency modulator and generating a radio frequency signal.    
     
     
         6 . The exercising hula-hoop assembly as recited in  claim 1 , wherein the remote receiver unit comprises: 
 a frequency demodulator for receiving the radio frequency signal transmitted by the radio frequency signal transmitter and supplying a demodulated signal;    a filter-amplifier for filtering and amplifying the demodulated signal supplied by the frequency demodulator and supplying a demodulated and amplified signal;    a decoder for decoding the demodulated and amplified signal supplied from the filter-amplifier and supplying a decoded signal;    a counting circuit for receiving and counting the decoded signal from the decoder and obtaining a count number in correspondence to depressed number of the depressible switch;    a microprocessor for receiving the count number of the counting circuit; and    a display unit connected to the microprocessor for displaying the count number thereon.    
     
     
         7 . The exercising hula-hoop assembly as recited in  claim 6 , further comprising an audio synthesizer and a speaker for generating an audio signal in correspondence to the count number.  
     
     
         8 . The exercising hula-hoop assembly as recited in  claim 1 , wherein the switch contact assembly comprises: 
 a pair of separated contact pads electrically connected to the radio frequency signal transmitter and fixedly located within the inner space of the exercising hula-hoop; and    a conductive member arranged in an opening formed on the interior surface of the exercising hula-hoop, facing the contact pads with a distance;    when the conductive member is depressed by a force applied from the interior surface of the exercising hula-hoop, the conductive member is moved toward and contact the contact pads.    
     
     
         9 . The exercising hula-hoop assembly as recited in  claim 8 , further comprising a waterproof layer formed on the opening of the exercising hula-hoop and covered on the conductive member.
