'RUBBER SOLE FOR SANDALS ATTORNEY.

Patented July 25, 1939 Application -October "22; 1938, Serial No. 236,371

(Cl. SG1-11.5)

2 Claims.

The invention relates to a sandal having a rubber sole and particularly to` an arch supporting sandal.

Many devices for the support of the instep arch 5 are known and used with shoes or boots.

In the majority of these cases the arch-supporting means consist of suitably shaped metal plates or pads and cushions of Aresilient material and many suggestions and attempts have been made to properly vconnect these arch supports I of Fig. 4,

with' the soles of the shoes, one of the most important requirements in this connection being that the dislocation and the displacement of the arch support is prevented and lits x'edposition .5 is ensured,

This problem of suitably and `properly locating the arch support however bears a fully different aspect ifthe support is to be used in a sandal.

A sandal by its very nature is not a tight fitting l0 article of footwear and is loosely connected with A the foot by means of straps. Consequently due to the loose fit a separate arch support of the ordinary type can not be held in place.

It is the object of the invention to provide for z the proper wearing relationship between thefoot,

the arch support yand the sole. 1

. With this purpose in view the rubber sole is shaped and manufactured .according to this invention integral with the arch `support. e04 It is afurther object-of the invention to pro-l vide improved means for accommodating and fastening the tying straps. This is accomplished by providing peculiar recesses premolded in the.

sole. x

36 7 It is a further objectl of the invention to provide a sole integrally molded in conformity with l the shape of the foot. 4

It is a further object to improve the fastening of the. straps to the sole so that the same will noticeable to the wearer.

All these improvements of the rubber-l forming the subject of the invention are effected during the manufacture or vulcanization thereof and the rubber sole therefore is a ready made,

' arch supporting unit for. mounting on' the same the further accessories o f the sandal. f

The invention is illustrated by way of example in the annexed drawings, ofwhich f Fig. 1 shows a top view of the sandal,

Fig. 2 shows a side view of the same,

Fig', 3 a sectional view according to of Fig. 1,` I'

Fig. 5 a side view of the same,

Fig. 8A a sectional view according` to line 8' 5- .of Fig. 1.

The sole I made of rubber has an outwardly curved ielevation 2 on its inside surface 3 which in the location of the instep arch ascends from the middle part ofv the sole and extends to the l0 inner side of the` same the outside curvature of this elevation 2 corresponding to the instep arch.

A series of recesses 4 are formed in the inner surface of the sole; thesel recesses exactly correspond to the'shape of the end portion of the tyl5 ing 'straps 5 which in order to be connected to the sole are inserted into ,these recesses. A

'I'he dimensions andthe depth of the, recesses which maybe arranged at suitable places are chosen in such manner that when the straps are inserted they lie flush with the upperA surface of the rubber solel The toe part 6 ofthe sole is preferentially upwardly bent and a concave curvature I corresponding totheshapepf the heel part of the foot is provided in the inside surface of the sole.

The straps are fastened to the sole by means of hollow rivets 9; for this purpose holes Ill and perforated washers II are provided inthe sole during the manufacture and vulcanisation there- '30 of. The end portions of the straps are inserted into the recesses and the rivets are driven through the same,' the holes of the sole and the washers; the ends of the rivets protruding within the sole over the Vwashers are flattened out over the out- 3'5l side of the same by a suitable pressingy tool.

Instead of using rivets the straps may also be sewed to the soles; the seams are preferentially located inside of the soles so that they are not visible from the outside.

After fasteningv the straps in' the described or any other suitable. manner the sole is covered by a leathenblank I4' of which'the shape correspondsfft the shape of the sole. 'An'elevated oughened marginal portion 8-is provided Von-the 45 f' inside surface of the sole. The depth of the strap receivingv recesses is such that the straps are ush with'the inner surface of the sole; if coveredvby the leatherblank a uniform continuous walking surface is created therefore and the straps will not create undue pressure on the foot of the wearer.

The heel I3 which also' is an integral part of the sole extends with its inner front edgeI I2 up to the arch supporting elevation 2.

The outside or the walking surface of the sole may be roughened in order to form an imitation of the crude or the so-called crpe rubber, 'or a thin sheet of this rubber may be cemented vto the walking surface of the sole.

With the integral arch supporting elevation, the integral heel, the recesses in the sole for the tying straps and the fastening means inside of the sole of the latter forms a ready-made archsupporting mounting unit.

What I claim is:

1. A rubber outsole for sandals comprising a heel and an arch support integral with said sole, recesses in the upper face of said sole for accommodating the ends of fastening straps, said recesses being of such a depth as to accommodate said straps in flush relationship with'the top surface of said sole, holes for receiving hollow rivets passing vertically through said sole and into the said recesses, said rivets being adapted to be attened out over the ends of the straps to be received in the recesses, an elevated marginal portion on said. sole, a blank vcovering .the inside surface of the sole and having its top face flush with the top' face of saidmarginal portion, said marginal portion extending continuously around the sole, said sole thereby forming aready-made mounting unit for the fastening straps and insuring the proper location of'the arch support in relation to the heel and to the straps.

2. A sandal comprising a rubber sole having an arch support integral therewith, recesses in its upper yface adapted to receive the ends of fastening straps with substantially the entire ends of -said straps in flush relationship to the upper face of said sole, said sole having a narrow, continuous" margin around its upper face elevated above the body of said rubber sole, foot engaging straps having their ends secured in the recesses, and a leather central element disposed in the recess formed by said margin, the top face of said centrai element being flush with the top of the margin.
