Nehus, Cincinnati, Ohio, assignor of one-half to Albert H. Bode, Cincinnati, Ohio Application October 9, 1935, Serial No. 44,209 7 Claims. g; This invention relates to an adjustable arch support and is concerned with supports of this kind. adapted under‘ one form to- be removably positioned in a shoe, and under another form, to be permanently positioned therein. An object of the invention is to provide an arch support adapted for ?ne degrees of adjust ment so that the wearer may determine the posi tion best adapted for his purposes and comfort. 10 ‘Another object is to provide an arch support adjustable in four directions, namely, upwardly and downwardly as well as forwardly and rear wardly. ' Another object is to provide an arch support, “ adjustable as described, but constructed of a minimum of parts so that the device may be manufactured at low cost and manipulated with ease by the wearer. Another object is to provide an arch support comprising a resilient pad removable to adjusted positions. Another object is to provide an arch support ing plate which contacts the inner ‘sole with which it is adapted to be associated at only three points whereby a particularly effective resiliency is achieved. ' , Another object is to provide an arch support unit which is immediately accessible interiorly of the shoe with which it is associated so that .90 the support unit may be readily adjusted and readjusted to suit the wearer’s needs with a mini mum of‘ time and e?ort. ‘ Another object of the invention is to provide . arch supporting means adapted for long periods 11: of usefulness. ‘ These and other objects are attained by the means described herein and illustrated in the accompanying drawings, in which: Fig. 1 is a perspective view, with parts broken away, of one form of the arch support unit of this invention. Fig. 2 is a perspective view of the intermediate ' .plate of the unit seen in Fig. 1. Fig. 3 is a perspective view of the bottom plate ’ of the unit illustrated in Fig. 1. ' Fig.4 is a cross sectional view taken on line 4-4 of Fig. 1. Fig. 5 is a perspective view of a modi?ed form of the intermediate arch supporting member, in , ' Fig. 8 is a perspective view of an inner cover or insole adapted to be used in a shoe provided with the support unit of Fig. 7. Heretofore various types of arch support units have been provided but these have possessed var ious disadvantages. Probably the chief disad vantage which has been common to arch units previously known, has been the lack of complete 10 adjustability. Some arch support units have been provided in which a support plate is pro vided with means, generally at the ends of the plate, for raising and lowering the plate to dif ferent arch supporting heights. Frequently, the means'for adjusting in this manner, have been 15 complicated and comparatively inaccessible so that an expert was required for making such adjustments. In addition to this, such arch units, while providing for the up and down adjustmentv referred to, have had no means for shifting the arch unit as a whole forwardly or rearwardly of the shoe to exactly the position required by the individual wearer. It is obvious that the rais- - ing and lowering of an arch is substantially use 25 less if the exact positioning of the unit as a whole has not been effected. The present invention overcomes these chief difficulties by providing, in the ?rst place, an arch support unit which is adjustable instan taneously by the wearer and without the services. of an expert, the adjustment means being acces sible and. visible interiorly of the shoe. In the second place, the present invention, by virtue of a central longitudinal slot and a main adjust- ; ment screw associated therewith, provides not only for the depression and elevation of the arch supporting plate, but likewise provides for shift ing of this plate bodily to the front or rear of the shoe, as may be required. In this way the proper 40 placing of the arch support may be obtained with absolute exactitude. ' The present invention likewise embraces var ious other advantages including ef?ciency of manufacture due to the simplicity and reduction of parts of the device. The degree of resiliency of the main ar'ch supporting plate of this inven tion has been greatly increased due to the novel three point support whereby said plate is associ , .Fig. '7 is a fragmental perspective view of a ated with the inner sole of a shoe. With reference to the drawings: The unit illus trated in Fig. '1 comprises an upper plate or cover In which may be formed of leather. The cover Ill may project from the heel of the shoe up to shoe having a modi?ed form of the arch sup the forward portions thereof. Said cover may be 55 the form of a resilient pad.

' Beneath the cover II], on the inner sole of a shoe, the bottom plate I4 of the arch supporting unit of Fig, 1 is adapted to be positioned. The position of the whole unit is substantially the same as that of the modi?ed form seen asso ciated with a shoe in Fig. '7.‘ Said plate I4 may likewise be provided at one side thereof, and ad. 10 . It may be-remarked that in the event that a very considerable forward and rearward adjust ment of the plate is required, the'screws-28 may 5.1 be removed from the initial perforations vI 6 and I‘! into which they were inserted and threadedly entered into other of said perforations. It'will be understood, however, that normally, the latitude jacent the front and rear extremities thereof," of movement made possible by the slots l2 and 21, with one or are adapted tures I3 of aperture I8, more perforations l6 and II which to register with the slots or aper the cover III. A central threaded on the instep side of the plate I4 is likewise provided. The main arch supporting member consists of an intermediate plate I9 (Fig. 2) consisting of a body portion 29, having front and rear resilient pronged extensions 2| and 22 extending, therefrom in alignment with one side, that is the inner lon gitudinal arch side, of the plate. Arlateral re silient extension 23 projects from the plate to Ward the side opposite the instep portion and along a ' line substantially intermediate the pronged extensions 2| and ‘22. It will be seen by reference to Figs. 2 and 4, that all of said ‘ex tensions 2!, 22, and 23 project into planes below provide for a Wide range ,of adjustment without the need of changing the screws 28 to otherrof the adjacent threaded perforations. In Figs. 5 and 6 a modi?ed form of interme diate member is illustrated. Thisconsists of a 15 resilient pad 29 having its greatest height or thickness on the instep side 39 and‘ tapered to ward the oppositeside thereof as indicated at 3|. The resilient pad is providedwith front and rear slotted extensions BI and 32 which are adapted 'to cooperate with’ suitable adjustment screws similar to the screws 28 heretofore described in connection'with Fig. 1. This pad may be shifted to the front and rear of the shoe but obviously is not intended'for use in instances where de pression and elevation of the arch support are required. ' ' ' In Fig. 7 a'modi?ed form of unit comprises a The plate I9 is provided along the instep por— a plate 33 identical with the plate I9'heretofore de the central or body portion 20 of the plate I9. 30 tion thereof, and centrally of the body 20, with a longitudinal slot 24 through which an adjust scribed but having under its pronged extensions 3O 34 and 35 small screw plates 36 instead of the ment screw 25 freely extends.

It will further beseen , of the invention seen in Fig. 7 is adapted to be‘ that the head 26 of the screw may be positioned permanently positioned in a shoe whereas‘ the in or upon the central aperture I2 of the cover I II. ' form illustrated in Fig. 2 is a removable unit. 45 The pronged extensions 2i] and 22, comprise longitudinal slots 2'! which are adapted'to register with the perforationsIG and I‘! of the bottom plate and with the apertures I3 of the cover III. A screw 28 (Fig. 1) projects freely through the aperture I3, the slots 21 of the pronged exten sions, and is threadedly receivable in perforations I5 and I’! of the bottom plate. 7 ‘The use and adjustment ofthe arch support unit just described is as follows: The device is positioned in the shoe and the wearer determines for himself whether the height of the unit is suitable for his purposes. If it'is to be lowered, the screw 25 is advanced into the perforation I8 60 so that the intermediate plate is depressed. If greater height is needed in the unit; said screw is retracted and‘ the plate thereby raised. It will be understood that prior to these adjust ments, the screws 28 which normally retain the 65 extremities of the pronged extensions 2I and 22 in contact with the inner sole 'of a shoe, are loosened so as to permitv a slidable relation of the pronged extensions with the bottom plate I4. The individual need as to height of the arch unit 70 having thus been attended to, the exact position ing of the unit of the intermediate plate It may be effected. This is likewise'a'ccomplished by loosening of the screws 25 and 28, the loosen ing of the former permitting the plate I9 to be Due tothe minimum of parts in the device of Fig. 7, the latter may readily and efficiently’be in stalled in both a new and an old ‘shoe. Fig. 8 illustrates a suitable cover or insole that may be used in the shoe with which the unit of . Fig. ' '7 is associated. When the adjustment screws of the arch support unit are to be regu lated, the insole III may be lifted'for giving access thereto. ' ' ' In both the units of Figs. 1 and’ '7; the inter- ~ mediate plates I9 and 33 have a-three point con tact only with the inner sole upon which they are positioned. This makes for highly ‘ef?cient re siliency in the arch support and likewise for a minimum of abrasion and wear, .on the inner sole. It will be seen, especially in Fig. 4, that the lateral extension of said intermediate plates, having no positive connection with either ‘the upper cover, the bottom plate'or the inner sole of thezshoe, is free to shift to the extent necessitated by any adjustment of the instep portions ofthe unit. . It will be further seen that the projection of said lateral extension intermediate the pronged ex tensions of the archv support plate results in grad ual tapering of the height of the arch support unit from the instep portion thereof toward the opposite‘ side of the shoe. The minimum of parts required of the present invention is in marked contrast with the similar elaborate ‘structures heretofore provided for similar purposes. Fur‘ 3 2,118,898 thermore, the reduction in weight as well as in material, of the unit illustrated in Fig. '7, makes of the intermediate portions of the plate, the screw further providing in the retracted position for forward and rearward shifting and adjust for greater comfort as well as greater economy in ' ment of the plate as a whole by virtue of said use and in manufacture. central slot.
