Stretch exercise apparatus

Abstract

A stretch exercise apparatus is durable, low cost, and easy to use for stretching the muscles extending from the bottom of the feet to all the way up to the back. The stretch exercise apparatus includes a base plate, a foot plate rotatably connected to the base plate, an angle adjuster established on either the base plate or the foot plate, engagement members established on the other base plate or foot plate without the angle adjuster to engage with the tip of the angle adjuster to set a desired angle, which greatly improves the ease of use. In a further aspect, a plurality of permanent magnets are embedded in both left and right foot pads on the foot plate.

1 . A stretch exercise apparatus for stretching muscles of a person, comprising: 
 a base plate;    a foot plate rotatably connected to said base plate;    an angle adjuster established on a lower surface of the foot plate, and    an engagement member established on an upper surface of the base plate for engaging with a tip of the angle adjuster.    
   
   
       2 . A stretch apparatus as defined in  claim 1 , wherein the angle adjuster is composed of a first angle adjuster for adjusting the angle of the foot plate in a large amount and a second angle adjuster for adjusting the angle of the foot plate in a small amount.  
   
   
       3 . A stretch apparatus as defined in  claim 2 , wherein the first angle adjuster is configured by a pair of first angle adjusting arms on left and right sides thereof, and the second angle adjuster is configured by a pair of second angle adjusting arms on left and right sides thereof, wherein the first angle adjusting arm is longer than the second angle adjusting arm.  
   
   
       4 . A stretch apparatus as defined in  claim 3 , wherein the pair of first angle adjusting arms are rotatably mounted on the lower surface of the foot plate, and the pair of second angle adjusting arms are rotatably mounted on the lower surface of the foot plate, wherein an adjustment knob is formed on each of the first angle adjusting arm and the second angle adjusting arm.  
   
   
       5 . A stretch apparatus as defined in  claim 1 , further comprising a pair of heel supports on the base plate for supporting heels of a person, wherein the heel supports are rotatably mounted on the base plate so that their angle can be changed in response to a position of the heel based on the change of the angle of the foot plate.  
   
   
       6 . A stretch apparatus as defined in  claim 1 , wherein an elastic member for reducing a weight of the foot plate during adjustment of the inclination angle of the foot plate is established between the foot plate and the base plate.  
   
   
       7 . A stretch apparatus as defined in  claim 6 , wherein the elastic member is a coil spring that is installed at the portion where the base plate and the foot plate are connected rotatably, wherein one end of coil spring is engaged with the base plate and another other end of the coil spring is engaged with foot plate thereby biasing the foot plate in a direction separating from the base plate.  
   
   
       8 . A stretch apparatus as defined in  claim 1 , further comprising a scale for showing the amount of flexibility when stretching on the foot plate.  
   
   
       9 . A stretch apparatus as defined in  claim 1 , wherein the base plate and the foot plate are made of polyacetal resin containing 20-30% glass fibers.  
   
   
       10 . A stretch apparatus as defined in  claim 1 , further comprising left and right foot pads made of non-slippage material on the foot plate, wherein each of the left and right foot pads is embedded with a plurality of permanent magnets.  
   
   
       11 . A stretch exercise apparatus for stretching muscles of a person, comprising: 
 a base plate;    a foot plate rotatably connected to said base plate;    an angle adjuster established on an upper surface of the base plate, and    an engagement member established on a lower surface of the foot plate for engaging with a tip of the angle adjuster.    
   
   
       12 . A stretch apparatus as defined in  claim 11 , wherein the angle adjuster is composed of a first angle adjuster for adjusting the angle of the foot plate in a large amount and a second angle adjuster for adjusting the angle of the foot plate in a small amount.  
   
   
       13 . A stretch apparatus as defined in  claim 12 , wherein the first angle adjuster is configured by a pair of first angle adjusting arms on left and right sides thereof, and the second angle adjuster is configured by a pair of second angle adjusting arms on left and right sides thereof, wherein the first angle adjusting arm is longer than the second angle adjusting arm.  
   
   
       14 . A stretch apparatus as defined in  claim 13 , wherein the pair of first angle adjusting arms are rotatably mounted on the upper surface of the base plate, and the pair of second angle adjusting arms are rotatably mounted on the upper surface of the base plate, wherein an adjustment knob is formed on each of the first angle adjusting arm and the second angle adjusting arm.  
   
   
       15 . A stretch apparatus as defined in  claim 11 , further comprising a pair of heel supports on the base plate for supporting heels of a person, wherein the heel supports are rotatably mounted on the base plate so that their angle can be changed in response to a position of the heel based on the change of the angle of the foot plate.  
   
   
       16 . A stretch apparatus as defined in  claim 11 , wherein an elastic member for reducing a weight of the foot plate during adjustment of the inclination angle of the foot plate is established between the foot plate and the base plate.  
   
   
       17 . A stretch apparatus as defined in  claim 16 , wherein the elastic member is a coil spring that is installed at the portion where the base plate and the foot plate are connected rotatably, wherein one end of coil spring is engaged with the base plate and another other end of the coil spring is engaged with foot plate thereby biasing the foot plate in a direction separating from the base plate.  
   
   
       18 . A stretch apparatus as defined in  claim 11 , further comprising a scale for showing the amount of flexibility when stretching on the foot plate.  
   
   
       19 . A stretch apparatus as defined in  claim 11 , wherein the base plate and the foot plate are made of polyacetal resin containing 20-30% glass fibers.
