14 Claims.
This invention relates to improvements in tread units for shoes.
In most shoes the outsole is made of leather or other flexible material of good wearing quality and it usually extends throughout the length of the shoe or at least throughout the length of the forepart and shank portions ofthe shoe. It is only in the foreparts of most shoes, however, that the outsole is subjected to wear and, accordingly, it has been proposed to conserve outsole material by providing tread units or outsole units each consisting of a forepart of leather and a rear part of a less expensive substance, such as leather substitute material or fiberboard. The rear parts of such tread units may advantageously be made of rigid material to afford better support for the heel and the instep of the foot and it-has been common to make them of wood or hardened plasm tic material. In all cases, however, it has been a diflicult problem to provide a satisfactory -connection or joint between' the forepart and the back part of a tread unit of this sortl One object vof the'present invention is to provide between the flexible forepart and the rigid back part of a tread unit for a shoe a joint of strong and durable construction which will enable the forepart of the unit to flex freely in use and-which will enhance the appearance ofthe -shoe in which the unit is incorporated.
With this object in view, the present invention provides a tread unit for a shoe comprising a back part, a forepart, and a joint or connection betweenI the parts having the novel construction and arrangement of elements illustratively disclosed in the following description and thereafter defined Fig. is a perspective view of the ba-ck part or wedge heel portion of the tread unit;
Fig. 6 is a view in longitudinal section of a tread unit of modified construction;
Fig. '7 is a plan view of a portion of the tread unit shown in Fig. 6;
Fig. 8 is a perspective view of a portion of the back part'or heel extension of the tread unit shown in Fig. 6;
Fig. 9 is a longitudinal sectional viewof a tread unit of still further modified construction;
Fig, 1l) is a plan view of a portion of the tread unit shown in Fig. 9; and
Fig. 11 is a perspectiveview of the locking or clamping plate employed in the tread unit shown in Figs. 9 and 10. r
As shown in Figs. 1 to 5, inclusive, the back part of my improved tread unit consists of a wooden wedge hee1 I2 and a short leather outsole I4. The wedge hee1 I2 is of a type commonly employed in sport shoes, platform shoes, andthe like, the heel extending forwardly to underlie and support the entire instep or arch portion of the foot and having a at tread face IB and an attaching face I8 which vslopes forwardly from the rear of the heel tothe front extremity thereof. The short outsole I4 is'ada'pted to underlie the ball and toe `portions of the foot and it is formed with an integral rearward extension in the form of a tab which extends into'and fits within a correspondinglyshaped shallow recess 22 (Fig. 5) in the upper side of the heel I2, the recess extending rearwardly from the front extremity of the heel. The outsole tab`20 is secured to the heel I2 by means of a suitable fastening, such as the screw 24. As shown, the tab 20 is split edgewise from its rear end to a location 26 substantially at the junction of the vtab with the body of the outsole. Thus, thetab 20 is divided into upper and lower leaves or Vlayers 28 and 3l), respectively (Figs. 3 and 4)', and a thin metallic locking or clamping Lplate 32 is interposed between the leaves of the tab. The screw 24 extends through a hole in the plate 32 and serves to clamp the lower leaf of the outsole tab between the plate and the heel. Two prongs 34 extend from the front edge of the plate 32 through the upper leaf 24 of the tab 29, the prongs being bent backwardly and downwardly against the upper surface of the leaf 28 so that they hold the tab 2G and the outsole I4 against edgewise turning displacement about the screw 24 and thus assist in locking orfastening the outsole securely to the heel. The depthk of the 'recess 22 in the hee1 is such that after the outsole tabf20 has been secured to the heel the upper surface of the tab will be iiush with the attaching face of the hee1.
The above-described connection yor joint bey tween the outsole I4 and the hee1 I2 lholds these two parts securely together to constitute a tread# member adapted for attachment as a unit to a shoe. The construction of the joint is such that the outsole or forepart of the unit is rendered capable of bending as freely as required to accommodate the flexing movements of the foot without risk of breaking or becoming weakened at the joint. Moreoventhere will be no fastenings such as screws, nails or rivets visible after the unit has been applied to the shoe. The outsole unit may be attached directly to a lasted shoe, or a middle or platform sole may be attached to the unit before the unit is attached to the shoe.
In the modified construction of my tread unit, as shown in Figs. 6 to 8, inclusive, the backpart of the unit consists of a wooden heel |20 having an integral undercut shank extension |22 to the upper side of which is attached by means of nails 50 the rearwardly extending tab portion |24 of a short outsole |40 which, together with a short middle or platform sole |42, constitutes the forepart of the unit. The tab |24 of the outsole |40 extends upwardly through a transverse slot 40 which is cut through the forward end portion of the heel extension |22 and rearwardly within a shallow recess 42 formed in the upper side of the heel extension. Forwardly of the slot 40 the heel extension |22 is notched or rabbetedat its lower side, as indicated at 44 in Fig. 8, to form a lip 46 beneath which the rear end portion of the middle sole |42 extends. The middle sole |42 may be secured to the lower side of the lip 46 and to the outsole |40 by Vmeans of cement and, as
shown, it may bei provided with an edge bindingv Ina still further modied construction ofl my tread unit shown in Figs. y9 to 1l, inclusive, the forepart of the unit comprises a short outsole 240 and a short middle'or platform sole 242 vwhich is secured jby cement or otherwise to tbe outsole. The back part of the unitconsists of a high heel 22D having an arched shank extension 222 the upper: side of the forward end portion of which is frecessed at 52 (Fig. 9) to'receive a tab 224 formedat the rear end of the outsole 246. A locking plate 54 is seated in the recess 52 beneath the tab 224, the plate 54 extending a short distance beyond the front end of the heel extension and having atransverse slot 56 formed therein through whichthe tab extends.` Forwardly of the slot 56 the plate 54 is bent downwardly to form alip 60 between which and the front edge of the heel extension-the base portion 58 of the tab 224 isbent substantially at 4right angles to the rest of thetabl and to the body of the outsole. .The body portion of the tab224 is secured to the heel extension v222 vby means of a screw `|52 which extends alsov through a hole 64 in the plate 54 and secures theplate in place. As shown, two screws 66 extend throughv holes 68 in the lip 60, through the bent portion 56 of the outsole tab and into theheel extension 222, causing the tab to be tightly clamped between the lip 66 and the 'front edge of the heel extension. Further to assist inholdingthe tab firmly in place, several shortr prongs 10, projecting from the plate 54 along the front edge'of the slot 56 are arranged to bite into the bent portion of the tab.
In the several embodiments of the invention herein illustrated the tread unit consists of a rear or heel member having a forward extension lfor underlying the shank portion of the foot and a front-member for underlying the forepart of the foot.' It'is to'be understood, however, that the rear part of the unit may extend no farther forwardvr than a 'conventional heel, that is, it may have no shank'extension, and the front member may extend rearwardly to underlie the instep or arch portion of the foot. In such a unit the joint between the front and rear members thereof will be located beneath the heel portion of the foot.
