SWIMMER TRAINING DEVICE
Abstract
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.

Claims
What I claim is:
1. 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 pin may be passed to maintain a desired height;
c. 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 weights which
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.
Description
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, 10
designates a base having a tubular socket 11 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
13 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.
