Patented Sept. 10, 1946 -1 UNITED STATES PATENT OFFICE SHOE Harry H. J oh'nson, Brookline, Mass. Application November 8, 1944, Serial No. 562,439
This invention relates to improvements in footwear and to sole structures for use therein.
In certain kinds of footwear such as ladies evening slippers of the sandal type, mules, and the like, a rigid shank is usually employed to maintain the proper relation between the sole and heel, the latter frequently being of the Louis variety. If an instep strap is provided to secure the shoe to the foot, the strap must be left quite loose as otherwise it will bind and chafe on the instep when the wearer walks. Consequently, when the wearer flexes the ball of the foot in taking a step, the heel of the wearer lifts away from the heel portion of the shoe sole, and the heel of the shoe clatters'on the floor as the foot is swung forward for the next step. Furthermore, when the foot which has lifted away from the heel portion of the sole descends again, it is liable to be offset to one side or the other so as to strike first on a side rim of that part of the sole, as a result of which the foot is apt to tire quickly. Such footwear well illustrates the objectionable features which my invention eliminates. a
It is an object of the invention to avoid thes troubles by providing spring means in the shank for causing the heel portion of the shoe to remain in contact with the heel of the wearer during walking, dancing or the like. According to the invention, a spring or its equivalent is incorporated in the shoe in such a manner as to tend to cause the sole to flex at the junction of the ball and shank so as to decrease the angle of the sole at said junction, that is, in such a manner as to tend to elevate the heel if the ball portion of the sole is held flat against the floor. This causes the heel portion of the shoe sole to remain against the heel of the wearer when the foot is flexed as in walking or dancing.
For a more complete understanding of the invention, reference may be had to the following description of certain embodiments thereof, and to the drawing, of which:
Figure 1 is a side elevation of an evening slipper or sandal, a portion being broken away to show in section.
Figure 2 is a side elevation of the same in flexed position.
Figure 3 is a bottom plan view of the same.
Figure l is a side elevation ofa modified form of the invention, partly broken away to show in section.
Figure 1 shows an evening shoe or slipper of the sandal type comprising a sole structure consisting of an outsole [0, an insole l2 and a sock- 6 Claims. (Cl. 362.5)
lining M. This shoe has a Louis heel It so that when the tread surfaces of the sole i0 and the heel I6 are in a common plane (as when in actual engagement with the floor) the angle between the top surface of the ball portion 13 and thetop surface of the shank portion 29 is approximately 130.
According to the invention, aresilientelement 22 of spring metal, plastic, fiber, or othersuitable material is mountedin or on the sole structure of the shoe in such a way as to tend to maintain the shank and heel portions of the sole at a materially steeper angle of inclination with respect to'the ball portion'of the sole than the corresponding angle in an ordinary shoe of the same size and style when off the foot. Thus, as shown, the spring means 22 may have a forward portion 24 secured by tacks, rivets or other means in the ball portion 18' of the sole between the outsole l0 and the insole I2. The rear portion 26 of the spring is preferably free and ex-' tends rearwardly up the shank portion of the sole, preferably terminatingforward of the heel portion of the sole; as indicated in Figure 1. The intermediate portion of the spring has therein a bend such that when in the position shown in Figure 1, the rear portion 26 presses upward so that if the ball portion of the sole is held down and the heel portion released, thelatter is raised and lifts the heel off the floor, as indicated in Figure 2. This condition exists when the foot of the wearer is flexed in walking or dancing. The weight of the wearer holds the ball portion of the shoe against the floor while the heel of the wearer rises to release the heel of the shoe. The effect of the spring action then is to cause the heel portion of the shoe to rise with the heel of the wearer, and to remain in engagement therewith. As indicated in Figure 2, the spring may fiex the sole so that the angle between the ball and shank portions is decreased to approximately 110 or even less. Since a shoe heel weighs little and does not have to be lifted far to follow the heel of the wearer, a light spring will suflice.
The springs illustrated in the drawing are shown disproportionately thick for clarity.
In order to avoid rapid wear of the insole [2 where it is pressed by the free end portion 26 of the spring element 22, I may provide a wear plate 30 on which the end of the spring may slide readily when the sole is flexed, the plate 30 being preferably secured by tacks or otherwise.
The invention is particularly advantageous in shoes having Vamps or toe straps 40 entirely or substantially unconnected with the heel portion of the shoe except by the sole itself. It is efiectiveand desirable even where, as illustrated, the shoe is provided with a heel strap 42 and an instep strap 44, or equivalent rigging. Such straps cannot be set up tight enough to be effective without causing objectionable binding and discomfort.
The spring 22 is shown in Figures 1 and 2 as built into the. shoe. The invention can also be readily applied to an already completed shoe. For example, as indicated in Figure 4, the spring may be secured outside of the outsole H], the spring having a bend tending to elevate the heel.
In the foregoing embodiments of the invention, the resilient element, which is a part of or is added to the sole of the shoe, causes the heel portion of the shoe sole to cling to the heel of the wearer so that walking, dancing, etc. are made easier, and fatigue is greatly reduced.
The foregoing description. of certain embodiments of the invention is by way of illustration and.not limitation, and. it isto be understood that the invention includes whatever variations and, modifications of form or structure may come Within the-scope of the appended claims.
I claim:
1 In an article of footwear, a sole structure whichhas ball, shank and heel portions and has aspring means incorporated within the ball and. shank. portions thereof and of such a strength and configuration as to resiliently maintain said shank and heel portions of the sole at a materially steeper angle of inclination with respect to said ball portion than the corresponding angle in an ordinary shoe of the same size and style when oif the foot, said spring means-having a forward portion in the ball of the sole, a. flexibly resilient intermediate portion and a rear portion extending rearwardly well into the shank portion of the sole, wherebywhen said footwear is wornv said spring means inherently presses the shank portion of the soleresiliently against the foot and tends to elevate the'shank and heel portions of the sole at alltimes during walking.
2. In an article of footwear, a sole structure as set forth in claim 1, wherein the rear portion of the spring means terminates forward of the heel portion of the sole.
3. In an article of footwear, a sole structure as set forth in claim 1, wherein the forward portion of the spring is substantially wider than the rear portion.
