INVENTOR ATTORNEY EXERCISING AND TEACHING APPARATUS FOR LIMB TRAINING AND FOR TEACHING SWIMMING The present invention relates to an exercising and teaching apparatus for limb training and for teaching swimming, particularly to teaching the arm and leg movement for swimming in the crawl stroke and in the back stroke.

It is an object of the present invention to provide an apparatus for teaching limb movement which is low in cost and easy to build, by means of which it is possible to teach the basic movements of swimming, with reference to crawl or back stroke.

An important feature of the teaching device of the invention is to provide a single exercising unit having a housing means with a central portion for the body and two side portions, one on each side of the central portion, with a first pair of mechanically operative means for training leg movements supported by the central portion in the rear portion thereof and having a reciprocating or oscilating motion along two vertical planes parallel to each other, and a second pair of mechanically operative means for training arm movements mounted on the side and controlled in an elliptical motion of translation in a plane along guideways inclined to the vertical. The first and second pairs of mechanically operative means facilitate alternate movements of the lower and upper limbs in accordance with movements corresponding to the crawl stroke and the back stroke. I

The invention will be more clearly understood from the following detailed description of a preferred, but not exclusive, embodiment thereof particularly with reference to the accompanying drawings, wherein:

FIG. 1 is a perspective rear view of the apparatus, partly in cross-section;

FIG. 2 is a front view, partly in cross-section; and

FIG. 3 is a top plan view of the apparatus, partly in cross-section.

Each sleeve element 12 pivots intermediate its ends at 8 on a shaft 9. The end of sleeve 12 extending to the right of shaft 9 co-acts with a cam disc 17 secured to a rotary shaft 19 whereby rotation of cam 17 oscilates the end of sleeve 12 and thereby gives an oscilating or up and down vertical movement to the leg training means 6 and stirrup 13. In a similar manner, cam disc 18, also secured to shaft 19, oscilates leg training means 7 and its stirrup 14.

Thus, the leg training means 6 and its stirrup 13 will be moved, say, down while stirrup 14 will be moved up. The movements given to stirrups 13 and 14 simulate the movements of a swimmers legs executing the crawl and back strokes.

Shaft 19, to which earns 17 and 18 are secured, is supported within housing portion 2 by suitable bearings and is rotated by a power unit 20 secured to the floor of housing 1. Unit 20 is preferably an electric motor provided with a reduction gear means suitable for powering the several mechanisms of the device. Unit 20 carries a sprocket wheel 21 which is connected by a sprocket chain 21A to a sprocket wheel 21B secured to shaft 19. Thus, chain 21A transmits rotary motion from unit 20 to shaft 19 and thereby to cams 17 and 18 for oscilating leg training means 6 and 7.

A shaft 22 is mounted in suitable bearings supported by the floor of the device. A sprocket chain drive 22A connects shaft 22 to power unit 20 to be driven thereby. The shaft extends through portion 2 and terminates in end portions 3 and 4 (FIG. 2). Pairs of bevel gears 25 and 26 couple shaft 22 to shafts 23 and 24, respectively. As illustrated in FIG. 2, shaft 23 secured at one end to a bevel gear 25 of the pair, carries a sprocket wheel 27 at its other end to support the arm training means in portions 3 and 4 so that they move in a plane inclined to the vertical.

An inclined support plate 32 is secured by bracket I means within the housing portions 3 and 4 generally parallel to the sloping or inclined walls 32A of portions 3 and 4. An endless member, such as a sprocket chain 29, is trained over wheel 27 and additional wheels 31 to form a general elliptical configuration. Gears 31 are supported on suitable pivots in plate 32. Similarly, a gear 26 is connected to a shaft 24 and a gear 28 supported by another plate 32 located within portion 4 (FIGS. 2 and 3), and a second sprocket chain 30 is trained around wheels 31 to form a configuration as chain 29 in portion 3 (FIG. 3).

An arm training means 35 is connected to chain 29 and a similar means 36 to chain 30. As illustrated in FIG. 2, each means 35 and 36 comprises a rod like element 37A telescoping in sleeve 37, whereby the overall length of means 35 and 36 may be adjusted.

To cause movement of means 35 and 36 in an elliptical path, elliptical trackways 33 and 34 are provided in the sloping walls 32A of portions 3 and 4. Arms 35 and 36 project through the trackways as shown in FIGS. 2 and 3.

A hand grip 38 is secured to each of the means 35 and 36 to be grasped by the user.

The operation of the apparatus of the invention is now described with reference to the leg movements in FIGS. 1 and and 3 and to the arm movements in FIGS. 2 and 3.

When the user who practices with the apparatus lies down on the body pad support 5 with his abdomen on the pad, the leg training means 6 and 7 are adjustable for his legs so that his toes fit into the stirrups 13 and 14 while his hands grasp the handles 38 which are secured to adjustable arm training means 35 and 36 guided in the elliptcal trackways 33 and 34. Obviously, if the back stroke is to be practiced, the stirrups 13 and 14 can accommodate the heels of the user, or the stirrups may be modified to accommodate heels.

From the foregoing, it will be observed that the preferred device employs a single motor and reduction gear for operating arm movements in an elliptical path in the directions indicated by arrows 42 and 43 shown in FIG. 3 and for operating the vertical reciprocating or oscilating paths of the leg moving means as shown by the arrows 40 and 41 in FIG. 1. The arms will be moved in planes which are inclined to the vertical to closely and accurately simulate the movement of the arms of a swimmer doing the crawl or back stroke.

I claim:
