(Cl. 36-115) This invention. relates to‘ footwear, and more mg two shown on opposite sides of the sandal. ' especially it relates to rubber bathing sandals. , The end portions of straps M are formed with The chief objects of the invention are to pro vide improved molded rubber bathing sandals; 5 to obviate the use of forms or lasts in the manu facture of rubber sandals; to provide a sandal consisting of a single unitary structure; to pro vide a sandal of such character that one sandal of any size is adaptable to the requirements of _ 10 several foot sizes, thereby reducing the amount of equipment required for the manufacture thereof, and reducing the number of sizes to be manufactured; to provide a ‘sandal that is in respective apertures I5 that are reinforced by re vspectivebosses IG' concentric therewith. ‘Ob-‘ viously the number and arrangement of- the Cl straps l4 may be varied to suit different styles and sizes of footwear. Y - Projecting laterally from each side of the shank portion of the sandal structure are respective instep portions l8, l8, which portions have front and side margins disposed substantially at right angles to each other, and are formed with re spective apertures i9 reinforced by bosses 20 at itially produced in ?at condition, thereby facili the rounded juncture of said, margins. Each 15 tating manufacture and conserving space‘ re-1 instep portion 68 is formed witha rearwardly ex quired for the storage and/or shipment thereof; tending strap 24 that extends'beyond the heel and to produce a molded rubber bathing sandal portion of the solestructure, and is formed with 20 at reduced cost of manufacture. _ Other objects an aperture 22 adjacent its rear end. will be manifest. portion of each strap i8 preferably is roughened 0f the accompanying drawing, ‘ Figure 1 is a side elevation partly in section of the improved sandal in its initial ?at or blank condition; Figure 2 lava bottom plan view thereof; The end on its underside as shown at 23, 23, and said end 20 portions are of diminishing thickness as is most clearly shown in Figure 1. Extending rearwardly from the portion desig ished condition, ready for wearing; and nated i3 is a heel strap 25 that is somewhat con-v stricted or narrower at 26, 26, adjacent the heel, 25 so as to be capable of ?exing thereat without Figure dis a section on» a larger scale on the line ?-t of Figure 3. , bulging or buckling. The underside of. strap 25 is roughened for about two-thirds of its length: Referring to the drawing, it will be seen that 1.30 the sandai blank is a one-piece rubber structure comprising an outsole portion H3 and a portion as shown at 2?, the rear half of said roughened portion being about half the thickness of the re mainder of the strap, as shown in Figures 1 and 25 Figure 3 is a top view of the sandal, in its ?n comprising insole and upper generally designated 4. Projecting downwardly from the roughened M, said portions b'eing vulcanized together to . portion of strap 25 is an integrallbutton 28, and form a single, unitary structure. It is possible the strap is formed with an aperture 29 located 35 to construct said portions ill and H of one piece, between the button and the free end of the strap. ‘* of rubber, but the arrangement shown is pre The under face of the several straps and instep ferred because it permits the outsole to be made portions, which become'the exposed faces in the of a tougher, more. abrasive-resisting composi ?nished sandal, may be ornamented in any de tion, and permits the outsole and upper to be sired design in the mold in which they are 40 made in contrasting colors. As is clearly shown formed. 40 in Figure 1, one face of the insole and upper H The sandals constructed as described may be is perfectly smooth, whereas the other side folded to ?nished form and provided with laces at thereof is formed with numerous protuberances the factory Where they are made, or they may including the outsole iii. Moreover, as original- ' be shipped to distributors and retailers in ?at 45 ly produced, the top, smooth face of the structure form and thereafter folded to ?nished form. 45 is disposed in a single plane. The arrangement The sandals may be compactly packed and stored ' is such that the sandal may be molded and vul while in their ?at form, so that shipping expense canized in a simple two-part mold having a mold is less when they are so shipped and the distrib ing cavity in one part only, the other part being so smooth and plain. The insole portion of the structure designated II is coextensive with the outsole I0 and is desig nated £3. The portion thereof referred to as the upper comprises short straps I4, l4 projecting 55 from the forward part of the structure, there be utor folds them preparatory to sale. In the operation of folding the sandals to ?n ished form, suitable rubber cement ?rst is ap plied to the roughened portions 23 and 27 of the respective straps 2i and 25. Then strap 25 is ?exed upwardly, and the end portions of the two straps 2| are buttoned onto button 28 of strap 50 2,110,939 2 25 by means of the apertures 22 in said straps. Then the end portion oflstrap 25 is folded over the end portions of-straps 2| and button 28 in serted through aperture 29 of said strap 25. The strap 25 is of such length that its end portion Ul may be adhered to itself, below the straps 2|, as shown in Figure 4. The‘ arrangement is such that the button 28 effects the accurate position ing of the end portions of the several straps, and sisting of a one-piece, vulcanized rubber struc ture comprising a sole portion, toe-engaging means at the forward end thereof, a rearwardly projecting heel strap at the rear thereof, and lat erally projecting instep portions in the'medial region thereof, said instep portions being formed with respective rearwardly extending straps, the terminal portions of the latter and the heel strap being‘ formed each with an aperture; and the heel strap being formed solely on one face thereof with an integral button that is adapted to‘pass through sion between the strap-ends by providing a me- _ said apertures, the other face of the heel strap . ' chanical interlock of the parts, whereby ‘a strong being smooth. 2. A footwear blank‘as defined in claim 1 in and durableunion of the parts is effected. thevapertured terminal portions of the The sandal is completed. by the insertion of a' which 15 straps are vthinner than the remainder of the shoe lace 3| through the apertures ii of toe straps strap structures, and are roughened on one face l4 and the apertures I! of the instep portions l8,“ as shown in Figure 3.
