Definitions

  • THIS INVENTION relates to an exerciser. More particularly, the invention relates to an exerciser for exercising under water.
  • an exerciser for exercising under water which includes two hollow tubular elements displaceable relative to each other, the hollows of the elements defining a chamber between them, the volume of which chamber is variable by the displacement of at least one of the two elements into the other; gripping formations for gripping the elements and facilitating displacement of the elements relative to each other; and at least one passage for permitting controlled displacement of water into and out of the chamber, the water displaced into and out of the chamber, being water from the under water environment.
  • the two relatively displaceable elements may include an elongate cylinder element and an elongate piston element reciprocably displaceable within the cylinder element, the piston element projecting from one end of the cylinder element.
  • the gripping formations may conveniently be handle formations secured to the opposite free ends of the cylinder element and the piston element, respectively.
  • Both the piston element and the cylinder element may be in the form of rigid elongate pipes or tubes blocked off at the free ends thereof where the handle formations are defined, these elements being of suitable materials such as a metal material, a synthetic plastic material, or the like.
  • the outer diameter of the piston element may be such that it snugly fits into the cylinder element while permitting reciprocal displacement between the two elements.
  • the passage formation may be in the form of a vent formation and, as such, the exerciser of the invention may include control means for controlling the effective size of the vent formation and, as such, the passage of water that can pass through the vent formation, when the apparatus is in use.
  • the vent formation may particularly be constituted by a series of apertures defined within the wall of the cylinder element near the end thereof where the handle formation is defined.
  • the control means may include a sleeve that is slidably received on the cylinder element between positions where only selected apertures forming the vent formation are exposed to permit the flow of water into or from the chamber defined between the piston and cylinder elements.
  • the exerciser 10 comprises an elongate rigid element 12 within which an elongate piston element 16 is reciprocably displaceable.
  • the cylinder element 12 and piston element 16 are of any suitable material such as a metal material, synthetic plastic material,or the like. More particularly, the elements 12 and 16 are in the form of elongate pipes closed off at the free ends thereof, a handle formation 14 being provided at the free end of the cylinder element 12 and a handle formation 20 being provided at the free end of the piston element 16.
  • the handle formations may also be of any suitable material.
  • the outer diameter of the piston element 16 is slightly less than the inner diameter of the cylinder element 12, thus enabling the piston element to be snugly received within the cylinder element while still permitting reciprocal displacement of the piston element within the cylinder element.
  • the two handle formations, 14 and 20, can clearly be gripped in order to permit reciprocal displacement of the piston element 16 within the cylinder element 12.
  • a flange formation 22 is provided on the piston element 16 near the end thereof opposite to its handle formation 20, the flange formation 22 providing for sealing engagement between the piston element 16 and cylinder element 12, thus preventing the possible passage of water between these elements.
  • a constricted lip 24 is provided at the end of the cylinder element 12 remote from its handle formation 14, the lip 24 serving as a stop that can co-operate with the flange formation 22 in order to prevent the piston element 16 to be completely retracted from the cylinder element 12.
  • both the flange formation 22 and the lip 24 also provide for sealing engagement between the elements 12 and 16, preventing possible leakage of water between these elements during reciprocating displacement of these elements with respect to one another.
  • the piston element 16 is inserted into the cylinder element 12 by shrink fitting the flange formation inside the cylinder element 12.
  • the exerciser 10 further includes a vent formation which is constituted by a series of apertures 18 defined in the wall of the cylinder element 12 near its closed end.
  • a control element in the form of a sleeve 26 is provided that is slidably displaceable on the cylinder element 12 and that can provide for selective exposure of one or more of the apertures 18.
  • the effective passage size leading into the chamber defined between the cylinder element 12 and piston element 16 is thus controllable for the purpose hereinafter defined. It will be appreciated that many other suitable arrangements can be provided for controlling the passage of water into or from the chamber defined between the cylinder element 12 and piston element 16.
  • An exercise routine can be carried out under water using the exerciser 10 completely submerged in water with one or more of the apertures 18 of the vent exposed.
  • This exercise is carried out by the reciprocal displacement of the piston element 16 within the cylinder element 12 which will require water to be drawn into the chamber defined between these elements through apertures 18 when displacing the handle formations away from one another, while this water must again be expelled through the apertures 18 when pushing the handle formations towards one another.
  • a user will have to impart predetermined forces for displacing the elements with respect to one another, thus exercising predetermined muscles of his body.
  • one of the elements 12 or 16 can be fixed to a side wall under water, the other element thus being displaceable for the same purpose as is hereinabove defined and described.
  • the exerciser 10 can form part of an under water exercising frame attachable to the side wall of a pool, which exercising frame can permit exercising under water.
