US 3861675 A
The present disclosure is directed to an apparatus having variable weights which may be attached to a line connected to a belt worn about the waist of a swimmer for applying weight to provide a restraining force against a swimmer attempting to swim away from the device which helps build, condition and tone the various muscles of the human body employed in swimming.

SWIMMER TRAINING DEVICE An object of the present invention is to provide a simple, inexpensive compact device which may be variably loaded to vary the restraining force which a swimmer must overcome in development of all body muscles employed in swimming, and particularly in training for competitive swimming events.
Another object of the present invention is the provision of a compact knock-down apparatus of the type described which may be transported in knock-down kit form and assembled in a minimum of time and which may be readily transported from site to site.
With the foregoing and other objects in view the invention will be more fully described heereinafter and more particularly pointed out in the appended claims. In the drawings in which like parts are denoted by reference characters throughout the several views:
FIG. 1 is a perspective view of the apparatus of the present invention, assembled and ready for use.
FIG. 2 is a perspective view of the apparatus of FIG. 1 in use by a swimmer poolside.
FIG. 3 is a top plan view of the base upon which the apparatus is mounted.
FIG. 4 is a side elevational view of FIG. 3.
FIG. 5 is a top plan view of the first or top pulley means. FIG. 6 is a perspective view of the weight connecting means.
FIG. 7 is a schematic showing a swimmer connected to a weight through a pulley and line system with the line attached to the swimmer.
Referring now to the drawings and for the moment to FIG. 1, l0 designates a base having a tubular socket l1 and an oblique stand-off 12 having a pulley 13 mounted thereon for free rotation. Receivable within the tube 11 is a vertically extendible post 14 in the form of a pair of telescopic tubes 15, 16 having openings 17 through which a locking pin 18 may be pressed to preserve the desired vertical height. At the upper end of tube 16 is a cap structure 19 having a first multiple pulley means 20 mounted for free rotation.
A second pulley means is shown at 21 having a frame 22 to which is releasably secured a weight rod 23, shown in FIG. 6, over which various weight discs 24 may be passed. The second pulley means has secured thereto one end of a weight line 25 and the line is roved back and forth between the first and second pulley means as shown schematically in FIG. 7. The line 25 is passed beneath the pulley l3 and attached to a belt 26 secured about the waist of a swimmer 27, shown in FIG. 2 practicing the butterfly.
In use the apparatus of the present invention is placed poolside as shown in FIGS. 1 and 2 and the swimmer puts the belt 26 above his waist and secures same by a snap hook to the line 25. Each swimmer can adjust the amount of weight he wishes to pull against and the vertical raising or lowering of the telescopic tubes 15 and 16 regulates how far out into the pool he may swim.
What I claim is:
l. A swimmer training device comprising:
a. a base;
b. an extendible post upstanding from said base having telescopic tubes having spaced openings along their length through which a locking pinmay be passed to maintain a desired height;
0. multiple pulley means mounted at the top of said post;
d. a second pulley means;
e. variable weight means releasably connected to said second pulley means comprising a stack of varying size and weight weightswhich may be added'or removed as desired;
f. swimmer attaching means in the form of a belt adapted to be secured about the body of a swimmer;
g. line means one end of which is secured to said second pulley means, said line means being roved back and forth over the multiple pulley means between said first and second pulley means and the other end of said line being connectable to said swimmer attaching means, and pulley guide means extending obliquely off said base through which said line means is passed and maintained close to a parallel attitude relative to the swimmers body in the water.
