Patented Oct. 1, 1 946 FOOI` APPLIANCE Bernard Ferrar, Chicago, Ill. Application September 30, 1943, Serial No. 504,364

3 Claims. (Cl. 36-7.8)

The invention relates to improvements in foo appliances and has for its primary object an improved foot appliance adapted to serve as a substitute for shoes, which is of simple construction and highly eicient in use Another object of the invention is the provision of an improved appliance of the character indicated which is equipped with special means for ready attachment or detachment of rollers.

Other objects will appear hereinafter.

The invention consists of the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this speciiication'and in which:

Fig. 1 is a side view of an appliance embodying the invention;

Fig. 2, a horizontal section thereof takensubstantially on line 2--2 of Fig. l;

Fig. 3, a side view of a modified form of construction; and

Fig. 4, a view of a set of rollers equipped with means for attaching them to the appliances shown in Figs. 1 and 3.

I'he embodiment of the invention illustrated in Figs. land 2 of thev drawing comprises a'lower tread member formed of two identical plates I0, each equipped with rubber tread members I I providedat their tops with iieXible resilient lips I2, by means of which said tread members may be readily reversed or interchanged on plates I3 to yields 'under shocks and strains to cushion vthe' walking, running, jumping or skating operations of the wearer, lbut will hold the foot rest member in proper relation with the corresponding tread members during all conditions and will prevent upward movement of the rest member beyond the point of initial compression of the Ysprings I6. Each rest member I4 is equipped with a foot instep band adjustably connected by lacing 2l with the sides thereof. A heel-embracing member `22 is connected at 23, as shown, with the rear of the rest member I4 and the forward ends of the member 22 are formed into securing straps 24 adapted and arranged to -adjustably engage buckles 25 on the rear edges of the instep band `2l). By this arrangement a secure and adjustable attachment for the foot is provided. and

one which may be readily applied to or removed from the foot by merely loosening or securing one of the side straps 24, as will be readily understood.

In the modiiication illustrated in Fig. 3, I have shown an arrangement in which the tread mem- Eber 26 constitutes part of a at spring and is equipped on its bottom with rubber blocks 2'I and 28 having spaces 29 lbetween* them. A resilient support for the foot restconsists of another part 30 of the ilat' spring and exible tie members or chains 3|-, 32 and 33 are connected as shown to limit the upward movement of the foot rest I4 y and further tie the members together.

rest I4 is resiliently supported by means of two coiled compression springs I6 fitting at their ends vover short posts or projections I' I on each of the plates I 0.

As indicated, each tread member IIJ- II is laterally extendedr at its outer side beyond the corresponding spring I 6 to prevent turning ofthe ankles of the wearer.- Crossed chains IB and I9 are arranged respectively, longitudinally in'the center ofr and at each end of each ofthe plates I0, having their ends secured to said plates and foot rest as shown. The springs I6 are placed under initial compression substantially equal to Athat of the person intended to wear the appliance,

and held under said tension by the chains I3 and I9. In this Way a resilientrmounting is provided for the foot rest member which readily In Fig. 4 I have illustrated a roller attachment for the appliance comprising a` square axle 34 for rollers 35 at its ends and spring clips 36, adapted and arranged to iit over the edges of the tread members IIJ--I I and 26 with the square axle 34 fitting into the notches or spaces I3 or 29, as the case may be.

While I have illustrated and described the prefer-red forms of construction for carrying the invention into effect, these are capable of varia,- tion and modification without departing from the spirit of the invention. I-Iowevery I do not wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall within the scope of the apflexibly resilient reversible interchangeable tread bodies having lips tting over the edges of said plates; a foot rest arranged above andresiliently supported on said tread member; and exible tie members placing said resilient support under tension and limiting the upward movement of 10 movement of said foot rest.

said foot rest.

3. A foot appliance having a tread member comprising two identical supporting plates; ilexible interchangeable tread bodies having lips tting over said plates; a foot rest arranged above and resiliently supported on said tread members; and crossed flexible tie members arranged longitudinally and laterally with their ends secured to said tread and rest members placing said resilient support under tension limiting the upward BERNARD FERRAR.
