Swimming training apparatus

Abstract

A swimming training apparatus automatically adjusts a user's position at the water surface of a swimming pool according to the user's swimming conditions by a resilient component installed in a position adjusting device. The swimming training apparatus includes an arc support structure, a position adjusting device and a connecting element. When the user swims away from the swimming training apparatus, the pulling force produced by the swimming winds the drive gear to store resilience to the resilient component. The gear set drives two rollers to move the position adjusting device towards a pool side. When the user stops swimming, the resilient component releases the resilience so that the drive gear shortens the connecting element and moves the position adjusting device towards the original position. The invention enables users to swim at different distances within a safe range or flow safely on the water surface of the swimming pool.

1 . A swimming training apparatus, comprising:
 an arc support structure, disposed at a first end of a swimming pool, and a second end of said swimming pool being higher than the water surface of said swimming pool;   a position adjusting device, installed at said arc support structure, and including a resilient component and a drive mechanism, and said resilient component being installed at said drive mechanism;   a connecting element, with an end wound to said drive mechanism and another end disposed at a user;   when said user swims away from said swimming training apparatus, said connecting element is pulled to drive said drive mechanism, such that said resilient component stores a resilience, and said position adjusting device is moved towards said first end; when said user stops swimming, said resilient component releases the resilience, such that said drive mechanism shortens said connecting element, and said position adjusting device is moved towards said second end.   
   
   
       2 . The swimming training apparatus of  claim 1 , wherein said arc support structure comprises a plurality of arc support stands, and said arc support stands can be extended and contracted with respect with each other. 
   
   
       3 . The swimming training apparatus of  claim 2 , wherein said arc support stand has an opening disposed vertically on a cross section of said arc support stand and in a contracting direction, and these openings face said user, such that said drive mechanism coils an end of said connecting element from said opening. 
   
   
       4 . The swimming training apparatus of  claim 1 , wherein said connecting element includes a rolling string, a cotton string and a waist belt, and an end of said rolling string is coiled to said drive mechanism and another end of said rolling string is coupled to an end of said cotton string, and another end of said cotton string is coupled to said waist belt, and said waist belt is worn by a user. 
   
   
       5 . The swimming training apparatus of  claim 4 , wherein said rolling string is a steel rope. 
   
   
       6 . The swimming training apparatus of  claim 4 , wherein said cotton string is an elastic rope. 
   
   
       7 . The swimming training apparatus of  claim 1 , wherein said drive mechanism comprises a casing, a drive gear, a gear set, two rollers, and two guide boards, and said casing has a fixing axle, and said drive gear is pivotally coupled to said fixing axle, and an end of said resilient component is latched into said drive gear, and another end of said resilient component is latched to said fixing axle, and an end of said connecting element is wound to said drive gear, and said drive gear drives said two rollers by said gear set, and said two guide boards are disposed at two guide grooves of said arc support structure, such that said position adjusting device is guided by said two guide grooves. 
   
   
       8 . The swimming training apparatus of  claim 7 , wherein said two rollers are made of rubber. 
   
   
       9 . The swimming training apparatus of  claim 1 , wherein said resilient component is a torque spring.
