Description:

This invention relates to an exercising machine of the type in which a motor means is adapted to move limb exercising members for moving the limbs of a person applied to parts of the limb exercising members. Machines of the particular class are well-known in the art, and in the main, comprise an electric motor that moves pedals or levers for moving the arms and legs of a person using the machine.

In the machine of the prior art, the limb exercising members are moved in predetermined cycles, and with no variation in the movement of the'limb exercising members relatively to one another. In this way, there is preserved a constant rhythm of movement that is easily anticipated and detracts from the exercising value of the prior art machines. It is the object of my invention to contribute an exercising machine in which the limb exercising members move relatively to one another in varying relationship while moving to exercise the limbs of the person using the machine.

As a feature of the invention, I utilizelimb exercising members that are movable by motor means relatively to one another in varying rela.. tionship, while movable individually to exercise the limbs of a body.

As a more particular feature of the invention, the limb exercising members are each movable through predetermined cycles, with the relationship of the cycle of one limb exercising member to the cycle of the other limb exercising member being :continuously varied.

SAs a more particular feature of the invention, I provide an extremely novel and simple means for moving the limb exercising members cyclically, while at the same time moving the said members relatively to one another in varying relationship.

Even more particularly, for contributing the particular features set forth, I utilize a single operating gear member,-which preferably is a worm, in -contact with two different gears that in turn operate the limb exercising members.

I have thus outlined rather broadly the more important features of my invention in order that 4 the detailed description thereof that follows may be better understood, and in order that my contribution to the art may be better :appreciated.

There are, of course, additional features of my invention that will be described hereinafter and which will form the subject of the claims nappended hereto. 'Those -skilled in the art will appreciate that the conception on which my disclosure is based may readily be utilized as a basis for the designing of other structures for carrying out the 5 several purposes of my invention. It is important, therefore, that the claims to be granted me shall be of sufficient breadth to prevent the appropriation of my invention by those skilled in the art. Referring now to the drawings, Fig. 1 is an elevation of an exercising machine embodying my invention. Fig. 2 is a plan view looking downwardly on the machine of Fig. 1. Fig. 3 is .a section taken along lines 3-3 of Fig. 1, while Fig. 4 is a section taken along lines 4-4 of Fig. 1.

Referring now more particularly to the drawings, the frame of my machine.is preferably constructed of a strip of steel having spring-like qualities and designated generally by reference numeral [i. Welded or bolted to the strip of steel 10 at -1, .are cross legs 12 that form an.adequate support for the:machine, resting on the floor or ground, as is quite apparent. The upper portion of-the steel strip 40 has secured thereto at 13 a suitable bicycle type seat 14 on which sits the person to be exercised.

The steel strip 10 is bent at 5 -to form a means for securing a bearing sleeve 1,6, best shown in Fig. 3. This bearing sleeve IS is secured relatimely to the bent portion 1.5 of the steel strip 10 through means of a bracket 17 bolted at 18 to the steel strip I10. As seen in Fig. 3, the bearing sleeve 16 has mounted therein for free rotation a pair of shafts 19, each grooved at 20 for a retaining stud 21 threaded into the bearing sleeve 16, and retaining the said shafts 19 against endwise removal from the bearing sleeve 16. It is, of course, appreciated that each of the shafts 19 is permitted to rotate freely in the bearing sleeve 16, though prevented against endwise removal therefrom.

Each of the shafts 19 is provided with a diametric bore 22, and secured in the bore 22 of the right hand shaft 19 of Fig. 3 is a limb exercising member or lever 2.3. The lever 23 is fixed to the shaft 19 by a stud 24, the stud allowing longitudinal movement of the lever 23 relatively to the shaft 19 for adjusting the position of the lever relatively to the machine.

5 The left hand shaft 19 of Fig. 3 has fitted in its bore 22 a lever 23a also secured thereto by a stud 24a similar to stud 24 of the right hand shaft 19: At the upper end of each of the levers 23, 23a there is ,secured a hand grip member 25 of a ;0 type known well in this art. At the lower end of each of the levers 2,3, 23a there is secured a.bicycle type pedal 2.6 on which .are applied the feet of the person being exercised. The pedals 26 may be secured relatively to any one of the series of 5 openings 27 formed in the levers 23, 23a. It will be recalled that the said levers 23, 23a may also be moved relatively to the shafts 19, thereby making it possible to adjust the machine for persons of different size.

Mounted on the bottom of the steel strip 0 under the seat 14, through suitable means, is an electric motor M adapted to rotate a worm gear 30 within a gear case 31. The worm gear 30 is adapted for engagement with a ring gear 32 and a ring gear 33, the ring gear 32 having sixty teeth 1 while the ring gear 33 has fifty-nine teeth. The ring gear 32 is suitably secured within the gear casing 31 to a shaft 34, and keyed to this shaft 34 at 35 is a crank 36. Crank 36 is pivoted at 37 to a connecting rod 38 that is in turn pivoted at 1 39 to the lever 23. It is obvious that the pivot point 31 may be changed by utilizing any one of the series of extra holes 40 formed in the crank 36. The transmission of motion to the lever 23 by connecting rod 38 may further be changed by 2 utilizing one of the openings 27 other than the particular opening utilized in Fig. 1.

The left hand ring gear 33 is secured within the gear casing 31 to a shaft 41 having keyed thereto at 42 a crank 43. Crank 43 is in turn pivotally secured to a connecting rod 44 at point 45. The connecting rod 44 is then secured at 46 to the limb exercising lever 23a. It is obvious that the drive of lever 23a is exactly the same as that of lever 23 except that one of the levers will be moved at a speed somewhat higher than that of the other lever because of the variation in the number of teeth of the two ring gears 32, 33.

Due to the extremely simple arrangement just described, it is obvious that each of the limb exercising levers 23, 23a will be moved in a cyclic path, but that the movement of one of the levers relatively to the other will change constantly from cycle to cycle. In this way there will be a constant changing of the relationship of the movement of the two feet of the person sitting on the seat 14 and also of the two arms of the person sitting on the said seat.

I have actually constructed and operated a machine in accordance with the drawings of this application, and have found it extremely satisfactory and desirable, contributing exercising motion to the body that is of extreme therapeutic value.
