June 9, 1953 w. BROCKMAN 2,641,249 ADJUSTABLE FOOT SUPPORT DEVICE FOR EXERCISING MACHINES Filed Jan. 17, 1951 Patented June 9, 1953 ADJUSTABLE FOOT SUPPORT DEVICE FOR EXERCISING MACHINES Emory W. Brockman, Hartsville, Pa., assignor to Healthomatic Corporation, Bala-Cynwyd, Pa.,- a. corporation of Pennsylvania Application January 17, 1951, Serial No. 206,450

12 Claims. I

This invention relates to new and useful improvements in exercising machines, and more particularly to exercising machines of the ty e and construction havin a seat and rotational foot support devices, for example, as disclosed in copending application for Exercising Machine, now Patent No. 2,565,348, issued August 21, 1951.

The principal object of the present invention is to provide a novel foot support device for the pedals of exercising machines of the type described which are selectively adjustable to variously position the foot of the user of such machine in predetermined fore and aft relation with respect to the rotational axis of the pedals so that different muscles in the foot and heel of the user may be exercised to varying degrees as desired or required.

Another object of the invention is to provide a foot support device for exercising machines of the stated type which includes means for supporting the lower leg of the user in an upright position against lateral displacement-such means being useful in the treatment of persons lacking in control of the muscles.

A further object of the invention is to provide a foot support device for the pedals of exercising machines having the foregoing features and characteristics which is of relatively simplified construction and highly eflicient and effective in use.

These and other objects of the invention and the various features and details of the construction and use thereof are hereinafter fully set forth and described with reference to the accompanying drawing, in which:

Fig. 1 is a side elevational view of an exercising machine of the stated type embodying a foot support device made in accordance with the present invention;

Fig. 2 is an enlarged fragmentary view in pershowing other details of the construction and arrangement of parts of the foot support device.

Referring now more particularly to the drawing, a foot support device made in accordance with the present invention is shown in conjuncr tion with an exercising machine of the construction described in Patent No. 2,565,348, aforesaid. Such a machine embodies a base structure ID. a

relatively fixed seat I2, a handle member l3 which is mounted for oscillatory movement toward and away from the seat 12, and a driven shaft M which projects laterally outward from each side of the machine and has fixed thereon the shank of a pedal or support IS, the latter being adjustably connected to the shank I5 by a sliding connection which may be secured in adjusted position, for example, by wing nut 11.

A foot support device made in accordance with the present invention comprises a block for body member which is fixedly secured in position fiat upon the pedal or support l6, for example, by means of screws 2 I. Extendin through the body member 20 in a direction longitudinally of the exercising machine and in the plane of rotational movement of the pedal l6 are pairs of passages 22 and 23, respectively, with the openings of each pair arranged alternately with respect to the other pair, for example, in the relation shown in Fig. 4 of the drawing.

Mounted for sliding movement longitudinally within the first pair of passages 22 are the spaced parallel rod elements 3| of a toe support section tion 25 which is fixedly mounted or secured in any appropriate manner to the said rod elements 24. The outermost rod element 24 is provided with an aligned series of notches 26 extending longitudinally thereof and facing laterally outward in position for engagement by a pin 21. The pin 21 extends laterally inward of the body member 20 through'a suitable opening therein and, acting on the outer end of said pin is a leafspringo'r the like 28 fixed to the body member 20 and operable normally to urge the pin 21 into one of thenotches 2-6 in the rod element 24 to thereby predeterminedly position the heel support section'25 with respect to the body member 20.

Mounted for sliding movement longitudinally with the second pair of passages 30 are the spaced parallel rod elements 3| of a toe support selection 32 which is fixedly mounted or securedin any appropriate manner to the rod elements 3| I The outermost element 3! is provided with an'aligned series of notches 33 extending longitudinally thereofand facing laterally outward in position for engagement by a pin 34. The pin 34 extends laterally inward of the body member 20 through a suitable opening therein and acting on its outer end is a leafspring or the like 35 fixed to the body member 20 and operable normally to urge the pin 34 into engagement with one of the notches 33 to thereby predeterminedly position the toe support section 32 with respect to the body member tion on the said toe section 32.

By the construction described, it will be apparent that the heel and toe support sections '25 and 32 of the attachment may be'sel'ectively positioned with respect to each other and to the attachment body member 20 tomeet different requirements. pressed pins 21 and 34 and sliding therodelements 24 and 3! relative to each other and to the body portion 20 the heel and. toe sections 25 and 32 may be selectively spaced relative to each other as required and the relative fore-and aft positions of these sections 25 and 32 in any given spaced relationship with rcspectto theattachment' body portion 23 may be provided.

In this manner the heel section 25 may be po sitioned adjacent or relatively close to the body portion 20 with the toe section 32 relatively spaced forwardly thereof sothat maximum exerelse is afforded the muscles in the heel and adjacent portions of the foot and leg of the user.

Conversely, the toe section 32 may be positioned adjacent or close to the attachment body portion 2!] and the heel section 25 thereof spaced- S'ubstantially rearwardly' of said portion 26 so that in the operation of the device the muscles in the forep'art of the foot are afforded maximum exercise.

In the treatment of paralytics and other persons having no control of the muscles in their legs it is necessary tosupport the leg at'a point just below the knee in order to retain the persons leg in proper upright position.

of the heel section 25 of the device a bracket 50. This bracket 59 rotationally receives the lower horizontal end portion of a rodor standard 52 which is adapted to-eXtend upward along thelower' leg of the person using the machine. Ad-

justably mounted upon the upper end portion of the standard 52' isa bracket 54' which carries a strap or belt 55 for attachment to the users leg at a point just below the knee. The lower end portion -5I of the standard 58- is provided wit-hacross-head portion 56 through the on posite' outer ends of which are threaded screws 5'! which may be adjusted to engage against the underside of the heel section 25. By virtue of this construction and by proper adjustment of the screws 51 the support or standard. 52 may be afforded limited pivotal movement between predetermined fixed limits asdesired or the said.

standard 52 may be fixedly anchored with respect to the heel section 25;

While a particular embodiment of the present invention has been illustrated and described herein, it is not intended to limit the invention to such disclosure, and changes and modifications may be made herein .and thereto within the scope of the following claims.
