various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof , which should be taken in conjunction with the heretofore described drawings . with reference to the drawings , fig1 shows the device of the present invention and is identified herein by reference character 10 . device 10 includes a frame member 12 which may be constructed of any light weight and rigid , or semi - rigid material such as aluminum , fiberglass , and the like . frame member may include a first hoop 14 and a second hoop 16 . hoop 14 and 16 attach to one another at connection points 18 and 20 . frame 12 includes means 22 for attaching frame 12 to a user 24 , fig2 . means 22 is depicted on fig1 and 2 as a pair of brackets 26 and 28 which fit over shoulders of user 24 . brackets 26 and 28 are extensions of hoop 16 but may be formed separately and be connected to other portions of frame 12 . means 22 may also include a belt strap 30 which buckles around the waist of the user . it may be seen that a portion 32 of frame 12 extends below the waist of user 24 . device 10 also includes an air foil 34 which may be a fabric covering 36 constructed of nylon , cotton , and the like . fabric covering 36 attaches to hoop 14 by the means of a plurality of fasteners 39 . with reference to hoop 16 , it may be seen that a fabric covering 38 attaches thereto by the use of fasteners 40 . although the device of the present invention may include a single air foil , such as the one found attached to hoop 14 , the embodiments shown in fig1 and 2 shows an air foil having fabric coverings 36 and 38 . the fabric covering associated with hoop 16 includes an orifice 42 which regulates the flow of air passing from fabric covering 38 to fabric covering 36 connected to hoop 14 . orifice 42 may be closed or opened with draw strings 44 or other suitable means . the lower portion 32 of frame 12 includes wings 46 and 48 which help balance the force created by the air resistance above the waist on air foil 34 thereabove . zippers 50 and 52 , as well as zippers 54 and 56 , may divert air from air foil 34 and thereby control the drag created on user 24 by the use of device 10 . zippers 50 , 52 , 54 , and 56 may be opened or closed by the user while moving by the use of strings which extend to the front of user 24 ( not shown ). in operation , the user attaches device 10 to himself by the use of shoulder bracket 26 and 28 in waist belt strap 30 . zippers 50 , 52 , 54 , and 56 may be open or closed as desired to regulate the drag force created by device 10 . in addition , orifice 42 may be opened or closed by the use of drawstrings 44 to fine tune the drag force on the user . the user then runs , walks , cycles , or otherwise moves with device 10 attached . the user derives a greater amount of exercise from traveling a shorter distance with device 10 then he would otherwise without using the same . thus , a smaller or more restricted environment for exercising may be employed by the user than normally is needed in his training . another embodiment of the present invention is shown in fig3 of the drawings . the device 10a includes a flexible frame member 60 which is constructed of a tubular member 62 , bent into a roughly horseshoe shaped configuration . tubular member 62 retains a degree of resiliency in this mode . means 64 is provided for attaching flexible frame member 60 to user 24 . means 64 may include an over - the - shoulder support 66 having a neckbar 68 and bent gripping bars 70 and 72 straps 74 and 76 aid the user in holding gripping bar 70 . cables 78 and 80 extend from tubular member 62 to based yoke 82 . the user slips between backbend 84 and strap 86 when using the device 10a . legs 88 and 90 extend to either side of user and connect to the ends 92 and 94 of tubular member 62 . an air foil 96 may be connected to flexible frame member 60 . device 10a also provides means for permitting the user 24 to deform flexible frame member 60 . such means may take the form of handles 98 and 100 which permit the user to pull in or push out thus deforming tubular member 64 . such activity , of course , requires physical excursion on the user 24 . thus , it may be seen that the user could exercise his legs and arms at the same time . while on the foregoing embodiments of the present invention has been set forth in considerable detail for the purpose of making a complete disclosure of the invention , it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principle of the invention .
a training device , especially useful for a runner utilizing a flexible frame member which is attached to the runner and may be deformed by the runner while in motion .
