Description

DETAILED DESCRIPTION OF THE INVENTION B. Prior Art Regarding the developmental relationship of the body to health, there is increasing interest in swimming and water recreation as a form of training. Although swimming a lap in a pool is a very effective exercise, many people tend to consider it monotonous and inappropriate for the development of upper body muscles. Therefore, many people are looking for other forms of physical training and intramuscular development that they can engage in while enjoying the water.

PROBLEM SOLVED BY THE INVENTION It is an object of the present invention to provide an arm, shoulder and upper body training device that can be used while a person is in a swimming pool or hot spring.

Another object of the invention is to provide a training device for arm, shoulder and upper body development having a device that changes the physical exertion required to operate the device.

Other objects and advantages of the invention will become apparent from the following description, particularly when viewed in conjunction with the drawings.

C.1 Means for Solving Problems In the practice of the present invention, we have a barperu-type device with a handle to be grasped by the user having enlarged portions at opposite ends. Each enlarged portion has a pair of mutually rotatable discs. The fan-shaped aperture through the disc can be positioned at varying degrees of display to vary the size of the effective aperture through the disc, thereby increasing the resistance that water presents to movement of the disc through the aperture. Adjust amount. Therefore, adjusting the rotation of the disc is effective at both ends of the training device - changing the "weight",
DESCRIPTION OF THE PREFERRED EMBODIMENTS AND OPERATION In particular, from the figures, the underwater training device of the present invention is used to be operated by a person P while standing or sitting in water 12, such as a swimming pool or hot spring 14. Of course,
The device may also be used in any body of water d'-3 as long as the water 12 is deep enough to allow movement of the device 10 below the surface without hindrance.

The training device 10 has a handle 15 in the usual shape of a barbell, interconnecting circular enlargements 16 at opposite ends. Each circular enlargement 16 has a sector opening 22 between the spokes.
It has an integrally formed outer ring 18 having a plurality of spokes or sectors 20 having . Near the center of the ring 16, the spokes 20 support the hub 2, which supports a short axle 26.
Ends within 4.

Rotatably supported on mandrel 26 is a second round disc 28 rotatably received within a passageway 30 provided within ring 18 . The disk 28 also has a sector opening 34 therebetween.
It has a plurality of solid sectors or spokes 32 having .

By rotating the disk 28 relative to the ring 18, the sector apertures 22 and 34 are brought to varying degrees of display, thereby adjusting the effective aperture through the two disks 20' and 28.

Any suitable device may be provided to fix the relative position of discs 20' and 28. For example, handle 1
A series of saw teeth 36 can be provided on the outer periphery of the disc 28 to be engaged by a pointed spring pawl 38 slidable within the disc 28 . Pawl 38 has saw teeth 36 aligned therewith.
and is biased by spring 40. Pawl 38 is raised by pulling knob 42 to retract the pawl, allowing partial rotation of the disc to the newly selected position. The knob is then released to allow re-engagement of the pawl 38, fixing the spoked wheel 28 in the new adjusted position. At the other end of the handle 15 the inlet 16 can be adjusted in a similar manner to vary the overall resistance of the device to movement through the water 12.

In use, a person stands or sits in the water and can pull the device through the water, causing arm muscles through the upper body by bending, twisting and engaging other lines opposed by the water's resistance to movement of the device. , develop shoulder muscles and other muscles.

Insofar as the invention has been described with respect to its preferred embodiments, modifications and variations thereof may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.

Claims (2)

[Claims] (1) a handle to be grasped by a person; and relatively flat, generally coplanar panels fixed to each end of the handle, each of which has a generally circular shape that resists its movement through water. a pair of relatively rigid, coaxial disks having surface areas and each said panel facing and engaging; around each said disk forming a generally equally angular sector opening between the sector spoke members; with sector-shaped spoke members of: so as to vary the representation of the sector-shaped openings in one said disc together with the openings in the other said disc so as to adjust the degree of resistance to movement of each said panel through the water; Apparatus for rotating one said disk relative to said disk; and a plurality of positions relative to the other disks such that the relative degree of resistance of said disk to said movement is visible and can be changed rapidly. a device for releasably securing said one disc to a selected one;
Where the panel is in any plane from parallel to perpendicular,
A person located underwater, further characterized in that the panel is in a condition to be grasped at any position around the periphery of the handle so as to be movable through the water in order to change the resistance to movement of the panel through the water. Training equipment used for. (2) The releasable locking device comprises a plurality of notches in a rotatable disc; and a spring-biasing member that engages a selected one of the notches. The training device according to item 1.
