Description:

This invention relates to exercising apparatus, and it relates more particularly to that type of apparatus in which the combined motions of a rowing machine and bicycle are employed for the purpose of exercising a multiplicity of muscles of the user at one and the same time.

The apparatus of the present invention is preferably so constructed that the various parts may be motor driven, although if desired the motor driving mechanism may be omitted and the apparatus actuated by the efforts of the user. Also the apparatus is so organized that if desired, the crank pedal mechanism employed as a part thereof may be removed and the apparatus operated by the motor without the pedal action.

The principal object of the present invention is to provide an exercising apparatus of the character aforesaid which will be simple and efficient in its operation yet relatively inexpensive in construction.

A further object of the invention is to provide apparatus of the character aforesaid which may be readily adjusted to persons of various sizes, whereby the same may have a greater range of usefulness than the machines at present in use.

A further object of the invention is to provide, in apparatus of the character aforesaid, improved means for supporting the seat and causing the same to rock to the proper extent during the operation whereby a proper tilting of the seat in its various positions may be obtained.

A further object of the invention is to provide, in apparatus of the character aforesaid, in which the seat, handle bars, and crank pedals have coordinated movements, improved mechanism for obtaining the desired motions of the several parts.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof in which: Figure 1 is a side elevation of an exercising machine embodying the main features of the present invention, certain portions thereof being broken away to illustrate the construction and arrangement more clearly; Fig. 2 is an end elevation enlarged of the lower part of the front end of the machine; and Fig. 3 is a vertical section enlarged taken approximately on the line 3-3 of Fig. 1.

It will be course be understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

Referring to the drawings, in the particular embodiment of the invention therein shown, 5 is a base member which may consist of a heavy wooden plank upon which the various parts of the apparatus are suitably mounted. The base member 5 may be provided with foot members which may consist of spring metal bars 6 extending transversely to the base member 5. Each of said bars 6 is bent over at its ends to form the legs 7, the lower ends of which may be provided with rubber shoes 8. This arrangement will provide a support for the apparatus which will have a certain amount of flexibility, contributing to a certain extent to the comfort of the user, and also serving to prevent the transmission of such shocks as may occur with the reversal of movement of the various parts of the apparatus from being transmitted to the building in which the apparatus is used.

Mounted on the base member 5 is a casting 10 having a pair of upwardly extending brackets I which serve as a means for supporting pivot pins 12 and 13. The pivot pin 12 is located near the lower portion of the casting 10 and serves as a means for pivotally supporting a seat lever 14 which extends upwardly therefrom.

In the upper end of the seat lever 14 there is mounted the seat post 15, having a head member 16 secured thereto, and to which the seat 17 is 0O connected by the pivot pin 18. The seat post 15 is adjustable in the upper end of the seat lever 14, being held in the desired position by tightening the bolt 19 which serves to contract the upper end of the seat lever around the seat post, the upper end of the seat lever 14 being split for that purpose.

Intermediate the extremities of the seat lever 14 there is provided an extension 20 which carries a pin 21. Pin 21 serves as a means for journalling a roller 22. The roller 22 bears against the working face of a cam 23 preferably in the form of an eccentric which is mounted on and keyed to one end of a shaft 24.

The shaft 24 is journalled in a suitable hollow housing 25, and internally disposed within said housing 25 is a worm wheel 26 which is also mounted on and keyed to the shaft 24. The worm wheel 26 is engaged by a suitable worm 27 mounted on and keyed to a shaft 28 which is disposed transversely to the cam shaft 24 and located below the plane thereof.

The worm shaft 28 is also journalled in the hollow housing 25. One end of the worm shaft 28 projects through the housing 25 and is provided on its outer end with one member 29 of a coupling. The other member 30 of the coupling is mounted on the end of the shaft 31 of an electric motor 32. The electric motor 32 is mounted on the base member 5.

The pivot pin 13, which is mounted in the upper ends of the upwardly extending bracket members II, serves as a means of pivotal support of a handle bar lever 40 which also extends upwardly therefrom. A handle bar post 41 is adjustably mounted in the upper end of the lever 40, being fixedly held in any desired position by tightening the bolt 42, which is provided at the split upper end portion of the handle bar lever 40.

The handle bars 43 are also adjustably mounted on the handle bar post 41, so that the same may be swung to any desired angular position with respect to said handle bar post 41 and held in such position by tightening the bolt 44 at the upper end thereof. The internal construction of the handle bar and post is not shown as the same is well known and commonly used in bicycles and any of such adjustable handle bar structures may be used for this purpose.

The handle bar lever 40 also has at its end adjacent the pivot pin 13, an arm 45 extending bell-crank fashion. The end of the arm 45 is connected by means of a pivot pin 46 to a link 47. The seat lever 14 is provided with a similar pivot pin 48 to which the other end of the link 47 is connected. The foregoing arrangement is such that when the seat 17 is actuated in one direction by the rotation of the cam 23 on the shaft 24, the handle bar lever 40, and the handle bar parts carried thereby, will be synchronously operated but in a contrary direction.

The handle bar lever 40 is also provided with a lug 50, near the pivot pin 13, by means of which a connecting rod is pivotally connected thereto. The connecting rod comprises two sections, .one section 51 being hollow and in which the other section 52 is telescopically mounted. The section 52 of the connecting rod is adapted to be fixedly secured at the desired position in the end of the section 51 by means of the bolt 53 which serves to clamp the same.

The section 52 of the connecting rod is provided with a head portion 54 which is pivotally connected as at 55 to a lug 56 carried by the seat structure at a point some distance in front of the pivotal connection 18 of the seat structure to the head 16 of the seat post 15. The foregoing arrangement is such that when the seat lever 14 and the handle bar lever 40 are moved toward and away from each other, the seat will be tilted so to bring the same to the most desirable positions with respect to the various other parts of the apparatus during the respective movements of the same.

The shaft 24 upon which the worm wheel is mounted, also carries, on one end thereof, a grooved pulley 60 which is keyed to said shaft.

The pulley 60 serves to drive a V belt 61 which in turn drives a grooved pulley 62 mounted on a shaft 63 preferably located in front of the brackets II which serve to support the pivot pins 12 and 13. The shaft 63 has a pedal crank 64 fixedly mounted on each end thereof, each of which is provided at its end with a pedal 65 of the type commonly used upon bicycles.

The pedal crank shaft 63 is journalled in a suitable casting 66, the base portion of which is provided with longitudinal ledges 67 which are seated in complemental grooves in an extension of the casting 10 which supports the other portions of the mechanism. The crank shaft casting 66 is retained against upward displacement by means of the plate members 68 which are bolted to the main base casting 10. The crank shaft casting 66 is also provided with a lug 69 internally threaded for engagement by a threaded bolt 70. One end of the bolt 10 is journalled in a lug 73 extending upwardly from the end of the base of the casting 10 and said bolt 70 is restrained against longitudinal movement by means of an enlarged head 71 and a collar 72 respectively disposed on each side of the lug 73.

The enlarged head 71 of the bolt 70 is provided with handle members 74 whereby the bolt 70 may be rotated when desired to shift the pedal crank casting 66 longitudinally to adjust the tension of the belt 61. It will of course be understood that, in lieu of the pulleys 60 and 62 and the V belt 61, a chain and sprocket arrangement may be provided similar to that used on bicycles.

A motor control switch 80 is mounted on the upper end of one of the upwardly extending brackets II so that the same may be conveniently operated by the user of the apparatus to start and stop the motor while the user is in position on the seat.

The operation of the apparatus will now be readily understood. The user first takes his position on the seat with his feet on the pedals and holding the grips carried at the ends of the handle bar. The switch 80 is now operated to start the motor and, upon the worm shaft being thus rotated, the worm wheel 26 will be actuated to cause the rotation of the shaft 24. The cam 23 mounted on the shaft 24 will thus be caused to rotate and the seat lever 14 will be oscillated backwardly and forwardly about its pivot on the pin 12.

As the seat lever 14 is thus oscillated the link 47, which is pivotally connected thereto and to the handle bar lever 40, will cause the handle bar . lever and the handle bars carried thereby to be Ssimultaneously oscillated but in an opposite direction to the movement of the seat lever 14 and the seat 17 carried thereby.

When the movement of the seat and handle bar levers takes place as aforesaid, the connecting rod comprising the sections 51 and 52 will cause the seat to be slightly oscillated with respect to the horizontal about the pivot pin 18 at the upper end of the seat post 15. By connecting the seat Sin the manner aforesaid to a portion of the handle bar lever, the proper degree of inclination of the seat to the horizontal, at the various positions of the parts, will be obtained, resulting in greater comfort to the user than would be the Scase if the seat were rigidly secured on the upper end of the seat post, or was provided with a parallel motion in a manner similar to that of the parallel motion seesaws which have heretofore been used. As appears in Fig. 1, for instance.

the seat tilts forward through an appreciable angle in its downward and rearward movement from the full line to the dotted line position.

This slight tilting action contributes to the comfort of the user in avoiding possible binding at the crotch when the trunk is pivoted rearward in the stretching movement imparted to the body when the parts are in position shown in dotted lines.

As the shaft 24 is rotated as aforesaid, to actuate the seat lever 14 and handle bar lever 40, the pulley 60 will also be rotated in unison therewith and, by means of the belt 61 and pulley 62, the pedal crank shaft 63 will also be rotated, but preferably at a higher rate of speed. When the pedal crank shaft 63 is thus rotated, the pedals 65 carried on the ends of the cranks 64 will of course be rotated in their respective orbits.

It should of course be understood that if desired the motor drive and worm gearing may be omitted whereupon it will be seen that upon the actuation of the pedals 65 by the user, the shaft 24, upon which the cam 23 is mounted, may be rotated by means of the belt and pulley connection between the shafts 24 and 63 hereinbefore described.

Also if desired, the pedal cranks 64 may be removed, and the seat and handle bar levers actuated without the pedal movement, in which instance, of course, suitable rests (not shown) for the feet of the user would be provided.
