Swimming assistance apparatus

Abstract

Disclosed is a swimming assistance apparatus, which is worn on a user's both feet to provide the user with buoyancy, such that the user can float on water and swim in a good swimming style while repeatedly moving the waist from side to side like a fish, thereby reinforcing the user's waist muscles. Persons who have knee joint arthralgia or backache or persons who have disability in the lower body can use the swimming assistance apparatus for medical purposes, such as pain relief or treatment.

1 . A swimming assistance apparatus comprising:
 a body comprising material buoyant to water and having a first terminal end and a second terminal end;   a first fitting hole which is formed within a first round path, as the first terminal end of the body is wound following a first round path, for receiving a user's first lower body;   a second fitting hole which is formed within a second round path, as the second terminal end of the body is wound following a second round path, for receiving a user's second lower body;   a first cut part which is provided between the first terminal end and the body as an opening of the first fitting hole for ease of inserting the user's first lower body into the first fitting hole; and   a second cut part which is provided between the second terminal end and the body as an opening of the second fitting hole for ease of inserting the user's second lower body into the second fitting hole;   wherein the first terminal end and the second terminal end are wound in same winding directions, so that the user's lower bodies are guided through the first cut part and the second cut part in opposite directions with respect to the body; wherein the user's lower bodies float on water by a buoyancy of the body when the user's lower bodies are inserted into the first fitting hole and the second fitting hole.   
     
     
         2 . The swimming assistance apparatus according to  claim 1 , wherein the winding direction of the terminal ends is clockwise direction. 
     
     
         3 . The swimming assistance apparatus according to  claim 1 , wherein the winding direction of the terminal ends is counter-clockwise direction. 
     
     
         4 . The swimming assistance apparatus according to  claim 1 , wherein a through hole other than the fitting hole is formed at a portion of the body. 
     
     
         5 . A swimming assistance apparatus comprising:
 a body comprising material buoyant to water; and   a fitting hole having an empty pillar shape and defined to penetrate the body for receiving a user's lower body,   wherein the fitting hole comprises a first fitting hole and a second fitting hole for respectively receiving user's first lower body and second lower body;   wherein a first entrance for ease of inserting the user's first lower body into the first fitting hole is formed as an opening at an upper side of the first fitting hole, and   a second entrance for ease of inserting the user's second lower body into the second fitting hole is formed as an opening at a lower side of the second fitting hole, wherein the user's lower bodies float on water by a buoyancy of the body when the user's lower bodies are inserted into the first fitting hole and the second fitting hole.   
     
     
         6 . The swimming assistance apparatus according to  claim 5 ,
 wherein a first terminal end of the body surrounding the first fitting hole is extended through a mid-upper side of the first fitting hole and a second terminal end of the body surrounding the second fitting hole is extended through a mid-lower side of the second fitting hole.   
     
     
         7 . The swimming assistance apparatus according to  claim 5 , wherein a first terminal end of the body surrounding the first fitting hole is extended toward a lower direction of the body and a second terminal end of the body surrounding the second fitting hole is extended toward an upper side of the body. 
     
     
         8 . The swimming assistance apparatus according to  claim 5 , wherein the first entrance and the second entrance are symmetrically formed with respect to a middle of the body. 
     
     
         9 . The swimming assistance apparatus according to  claim 5 , further comprising a hand-grip. 
     
     
         10 . The swimming assistance apparatus according to  claim 9 , wherein the hand-grip is formed at a portion of the body. 
     
     
         11 . The swimming assistance apparatus according to  claim 9 , wherein the hand-grip is in a form of a hole. 
     
     
         12 . A swimming assistance apparatus comprising:
 a body comprising material buoyant to water; and   a fitting hole having an empty pillar shape and defined to penetrate the body for receiving a user's lower body,   wherein the fitting hole comprises a first fitting hole and a second fitting hole for respectively receiving user's first lower body and second lower body; and
 a through hole formed at a portion of the body; 
 wherein a first entrance for ease of inserting the user's first lower body into the first fitting hole is formed as an opening at an upper side of the first fitting hole, and 
 a second entrance for ease of inserting the user's second lower body into the second fitting hole is formed as an opening at a lower side of the second fitting hole, wherein the user's lower bodies float on water by a buoyancy of the body when the user's lower bodies are inserted into the first fitting hole and the second fitting hole. 
   
     
     
         13 . The swimming assistance apparatus according to  claim 12 , wherein the through hole is formed at both ends of the body. 
     
     
         14 . The swimming assistance apparatus according to  claim 12 , wherein the through hole has a polygonal or circular shape.
