s crarms; (o1. em -v)- 1 'I'h-is invention. relatesto. improvements in aps-- paratus. for treatment of the feet and: more particularly to apparatusthrough use of: which the bonesiofi th feetwilr be restored to their proper positions and the muscles. ot the feet will be. ex-- ercised, the apparatus while in use: being fully under the control of the patient and not requir an operator other than the patient; Y
The wearing of improperlyfittingshoes, lack,
or exercise or improper walking maylead to various. pathological conditions. of the feet. Treat--- ment of: such conditions. has -beenby foot exercises performed by thepatientor manual therapy applied by. the hands of a podiatrist.
The object, and purpose of the improved apparatus herein. disclosed isto enable a patient by theuse of the apparatus to attain thecorrective' results which would beaccomplished bya trained and expert manual therapeutistwhile at'thesame time the foot musclesare exercised to-retai'n the correctionsand adjustments. a I
It is particularly an object of my invention to provide apparatus-whichmay be used in the home by the patient to simultaneously exercise both feet while at the same time corrective pressure is; applied? to produce flexing ofthe b'ones of the iootsandreturni ofthe arches of the foot to their normal positions. a
It isa further objectof my' invention to provideapparatus which maybe used for the-treatment of the feet; in: a variety-of positions with the. patient either sitting or standing, the vari ably applied weight of the body being used to produce the corrective pressure.
Another. objectof'my invention is the provision of apparatus consisting of'a base and a pair of pivoted pedals adapted/to be engaged by the plantar surfaces of the pair of feet, the pedals having raised; portions thereon to engage the longitudinal and metatarsal arches of the feet and; being further. provided with strap means to produce fixation-of the forepart: of each foot so that the corrective pressures 'will beproperly applied; 1
The-features of my apparatus which are deemed to. be important include; the provision of a rigid baseor pedal against which the foot is pressed, thErbESG or pedal having arch: engaging portions thereon. the curvatures of. which are. emphasized beyond. the normal curvatures of the arches, the provision of: a pair of pedals adapted'to be simultaneously engagedby both feet enabling the apparatus held in place by one foot while tension is being applied the other foot, and the provision. of. means comprising straps for producing. finatibna oi? the. iion'ep'arts of the feet to; produce twisting and; flexing. of the bones of the: feetzas; pressure. is applied; to. the arches.

In Fig. lithe heel end of the pedal isin contact with the platform': H]; a suitable cushionor bumper-362 being used if'desi'red so asto scftenthe ca tact. Similarly; cushion'stops 38 may-beappl'ied arches of the foot comprising the inner longitudinal arch and the outer longitudinal arch or the weight bearing portion of the outer side of the foot. The top surface of the pressure member for the longitudinal arches of the feet is preferably formed substantially cone-shaped as shown. The
members 40 may be separately shaped and atably formed with a raised arcuate portion 42,
which serves as a. stop or abutment by engaging the outer longitudinal arch of each foot. The curvature of the pressure members 40 is designed to exaggerate the curve of a normal arch so that when the foot is applied to the pedal and pressure applied thereto a more pronounced curvature will be imparted to the longitudinal arch of the foot.
In addition to the provision of the conical members 40, I provide on each pedal a cylindricalshaped member 44 which extends forwardly from the mid portion of the conical member 40. Each member 44 is smoothly rounded at its forward end. The members 44 form the pressure members which engage the metatarsal arch of each foot. Each of the members 44 is secured to the associated pedal by the provision of a screw 46. It should be particularly noted that each member 44 is made long enough to accommodate feet of varying sizes and it is not necessary toprovide any adjustment as the metatarsal arch will always come in contact with the member 44 at some portion of its length.
In order that the device may be effectively used, some means must be employed to hold the forepart of the foot in position and I provide for this purpose the strap members 48. The ends of each strap are turned and stitched together to provide the looped portions 50 which engage the rods 52. A pair of the rods 52 extend along the sides of each pedal and the rods 52 are fixed at their forward ends by the screws 54. The rear ends of the rods 52 engage. the stop members 56, the outer ends of which are downwardly turned as shown in Fig. 5. The rods 52 may be pushed downward in order to permit removal of the strap 48 from the rods.
The straps 48 may also be adjusted as illustrated in Fig. 5. In this figure one of the looped ends.50 of the strap has been removed from one of the rods 52 and the strap passed between the rod and the side wall of the pedal. In this position the strap is shortened which may be desirable for small feet. It will be understood that the stop members 56 serve to hold the rods against upward movement when tension is apfoot must be strapped or taped in order to prevent immediate return of the bones of the foot to the position before treatment.
It is also well known that there are certain exercises which can be performed to improve the condition of the feet, but in such foot exercises the foot is not held in position by pressure so that a stretch may be applied between the point of pressure and a fulcrum as is the case in manual therapy. p
The device which I have disclosed provides means by which the advantages of manual therapy are combined with the advantages of foot exercises. With my device both feet are placed in position on the pedals as shown, for example, in Fig. 6. The transverse conicalmembers tend to raise the longitudinal arch of the foot. The metatarsal portion of the foot is applied against the cylindrical-shaped surface of the member 44 against which it is held by the strap 48. The device may be used with the patient in a seated position in which position the individual feet may be alternately pressed forward and retracted by movement of the pedals up and down. In Fig. 8, for example, the left foot has pressed the pedal down and serves to hold the base of the device in position while the right foot and the associated pedal is raised. The patient or user may apply just the desired amount of pressure. Initially the feet may be tender and too much pressure may cause. pain and discomfort. Therefore, only a small amount of pressure may be first applied but the pressure may be increased as the foot condition improves. With the patient in a seated position, spreading the knees apart tends to apply more ressure to the outer longitudinal arches of the feet. Furthermore, the user may slide the device ,on the floor forward or to the side to increase the strain. Thus in Fig. 7 the legs are at a sharp angle with respect to the base of the device and a twisting pressure is applied to the feet. v
In order to obtain more effective pressure than can be applied with the .user of the device in a sit- I ting position, the user may be standing up as is the case in Fig. 6. In this position the entire weight of the body is transmitted to the plantar surfaces of the feet 'which are resting upon the arch supportingprojections on the pedals. In the standing position the feet may be alternately moved up and down as in walking and the muscles of the legs will be exercised aswell as the muscles of the feet. I
