' l rTaR/VEY atented `une v1V 7, 1947 UNITED STATES PATENT OFFICE COMBINED SKATE AND SANDAL Bernard Ferrar, Los Angeles, Calif. Application December 27, 1943, Serial No. 515,682
The invention relates to improvements in foot appliances and has for its primary object the provision of an improved foot appliance so constructed and arranged as to provide surface-contacting means such as roller skates, ice skates or skees, and which is capable of economical production and highly eiiicient in use.
Another object of the invention is the provision of an improved appliance of the character indicated which may be readily converted into a substitute for shoes when desired.
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 drawings forming a part of this specification, and in which- Fig. l is a side view of an appliance embodying the invention;
Fig. 2, a horizontal section thereof taken substantially on line 2 2 of Fig. l;
Fig. 3, an enlarged section taken substantially on line 3-3 of Fig. 2; and
Fig. 4, a side View of the construction in condition for use as a substitute for a shoe.
The embodiment of the invention illustrated in the drawings comprises a foot rest l provided with a top pad 4Il of felt or the like, and held in place on the foot by means of an instep band l2 adjustably connected thereto by lacing I3, as indicated. A heel-embracing member i4 is connected at I5 as shown, with the rear of the rest member I0, and the forward ends of the member I are formed into securing straps i6 adapted and arrangned to adjustably engage buckles on the rear edges of the instep band as shown. 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 I 6, as will be readily understood.
Two spaced ilexible attaching elements are arranged to extend downwardly from the heel and toe portions of the foot rest I0. Each of these attaching elements comprises four spaced compression springs Il fitting at their ends over short posts or projections I8 on the underside of the rest I0 and on top of a corresponding supporting plate I9 as indicated. A flexible tie member in the form of a chain 20 is positioned centrally in each attaching element and serves vto hold the springs I'l under suitable initial compression and to limit their expansion, said springs being placed under sufiicient initial compression substantially equal tothat of theperson intended to wear the appliance, and being held under said tension by action of the corresponding chain 20, as will be readily understood. A suitable flexible housing 2|, preferably of leather or similar material, is arranged as indicated around each set of springs I'I and a rubber cushion or tread block 22 is provided with a exible lip 23 at its top adjustably securing the same to the projecting edges or shoulder of each plate I9 as shown. Surface-contacting means in the form of a steel plate 24 having up-turned stiffening anges 25 at its sides is detachably secured to each supporting plate I9 by means of upwardly and inwardly extending attaching lips 26 formed at each end thereof, and adapted and arranged to engage over the projecting edges or shoulders of the tread members 22-23 as indicated, and whereby the member 24 may be readily attached to, or detached from said attaching elements. Each member 24 is provided, as shown, with two transverse axles 21 carrying rollers 28, thereby completing a surface-contacting means in the form of an ordinary roller skate. By this arrangement the flexibility of the attaching elements permits of the ready attach`r ment or detachment of the members 24 and also provides the necessary lateral resiliency to permit of full and complete use of the attachment as an ordinary roller skate. By this arrangement a simple and effective foot appliance adapted to serve as a roller skate, ice skate or a skee may be readily attached to each foot of the wearer and the same fully cushioned and flexibly mounted so as to permit of the full and complete use and enjoyment thereof.
If and when desired, the surface-contacting means may be readily detached and the appliance then used as a shoe substitute as indicated in Fig. 4.
While I have illustrated and described the preferred form of construction for carrying the invention into eect, this is capable 0f variation and modication without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modification as fall within th'e scope of the appended claims.
