Patented Aug. 6, 1946 UNITED STATES PATENT OFFICE NOVEL SHOE CONSTRUCTION Meyer Margolin, Elgin, Ill. Application November 11, 1944, Serial-No. 562,996
My invention relates to a novel type of play shoe or platform shoe and more particularly my invention relates to a novel comfortable play shoe or playform shoe such as for example the California type shoe.
Play shoes and platform shoes are common in the art but they have certain undesirable characteristics, among which are lack of a desirable flexibility, rigidity both longitudinally and transversely and unyielding hardness of sole an-d foot support.
Accordingly, although the style and appearance of this type of shoe is attractive and creates a demand, the sale of this type of shoe has been retarded by its' lack of comfort.
It is the object of the present invention to provide a novel type of play shoe having a soft and resilient sole or foot support.
It is a further object of the present invention to provide a novel type of shoe of the so-called California type characterized by novelty and style and have comfort and exibility in wear.
It is a further object of my invention to provide a novel insole and middle sole structure for imparting to a shoe of the type described increased comfort and exibility.
It is a further object of the present invention to provide a shoe of novel appearance but with feature of comfort hitherto unobtainable in the art.
The objects of the present invention are accomplished by providing a relatively thick insert so disposed in the center of the forepart of the foot so that a resilient and comfortable support is aorded to the foot. The insert is disposed substantially centrally with respect to both the insole and the middle sole and is held in place by a so-called sole cover and outsole.
I may also employ a sole or middle sole of resilient material such as cork or rubber, provided With a central resilient insert, the insole of resilient material being bound firmly by a material to enable it to be properly secured with respect to the shoe upper.
The specific structures by means of which the objects of my invention are obtained are specically set forth hereinafter. In this connection reference is made to the drawing in which Figure 1 is a side view in partial section of the novel shoe of my invention.
Figure 2 is a cross section of the forepart of a modified form of the shoe of my invention.
Figure 3 is a detailed View of that side portion of the shoe where the upper is joined to the insole 2 showing the manner of securing the upper on to the shoe bottom.
Figure 4 is a side view in partial section of a modified form of the shoe of my invention.
Figure 5 is a front cross sectional view of a still further modified form of my invention in which the insert has grooves and perforations.
Figure 6 is a detailed showing of a side portion of the shoe of my invention illustrating the binding on the middle layer and the manner in which the upper is secured.
Referring now more specically to the drawing, in Figure 1 I show a shoe comprising an upper Iy a heel portion II and an outsole I2. The feature of this construction lies in the fact that disposed in a common opening in the insole I3 and the relatively thick middle sole I4 isi disposed a resilient insert I5.
The resilient insert I may be formed of rubber, sponge rubber, soft cork or any other suitably resilient and soft material. A sock lining I6 is disposed over the insole I3 and the insert I5. The exposed peripheral portions of the insole I3 and the middle sole I4 are protected by bindings I8 and I3.
In the resilient insert I5 are disposed perforations which extend therethrough to provide increased resilience and ventilation. By providing the single resilient insert I5 in the common opening provided in, the forepart of the insole- I3 and the middle sole I4, I provide both for increased sof-tness and resilience in the support for the forepart of the foot and I also firmly x or position the insole I3 and the middle sole I4 with respect to one another to prevent their shifting in the course of wear or exing.
It will be noted that the middle sole and the insole lie in a novel position with respect to the general shoe assembly.
In Figure 2 I show a cross section of the forepart of a shoe as described in connection with Figure 1, the modied form of Figure 2' distinguishing in that the insert 22 is provided with grooves 23 as well as perforations 24. The upper 3B is lasted to the insole 3| and the middle sole 32 is bound with a binding 33. The outsole 34 is secured to the middle sole. It will be noted that the resilient insert 22 occupies a common cavity of the insole 3| and the middle sole 32.
In Figure 3 I show a modied form of my invention in which the middle sole 4l! may comprise a resilient material such as rubber or cork. The insole 4| may also be formed of a resilient material such as rubber or cork. I have found that by providing a binder such as 42 on the middle sole 40 and a binder 43 on the insole M about the peripheral exposed edges of such middle sole and insole, that I can While providing a desirable decorative effect also permanently restrain the resilient insole or middle sole from spreading or squeezing out under pressure of the foot in the shoe.
In Figure 4 I show a platform type of shoe in which the upper 50 is secured as shown specically in Figure 6 to the binding 5l and the sock lining 52. The platform is provided by a relatively thick middle sole 53 in the center of the forepart of which is disposed a resilient insert 54 of rubber or the like. In the resilient insert 5e are grooves 55 and perforations 56 to provide for increased comfort, ilexibility and air transmission.
The edges of the middle sole 53 are firmly bound with a binder 5l which as pointed out above is secured to the upper 50. The sock lining 52 together with the outsole 5l maintain the resilient insert 54 in its proper position in the opening in the forepart of the middle sole 53.
The resilient insole and middle sole can extend either from the toe to the ball portion of the shoe or it can extend entirely from toe to heel. The insert 54 may be provided with a peripheral extending lap 59 which extends over the adjacent portion of the middle 'sole 53 and is secured thereto b'y stitching not shown. Similarly the various resilient inserts described in the various modified forms of my invention herein may be provided either with a single lap or both an upper and lower 'lap whichV extend over in the form of a graduated Yfeather edge over the adjacent portion of the middle sole or insole.
By'the structures herein described, I provide a play shoe or platform type of shoe having both transverse and longitudinal flexibility with greatly increased foot comfort by reason of the soft `and resilient supporting portion in the forepart ofthe shoe and by the provision of the binding and lasting of upper as described I secure at the Sametime a permanently nrm shoe structure. Thus, I obtain the desirable thick platform eiect without sacricing the comfort of the shoe to the wearer.
I may also employ this platform type construction that I have described, particularly the thick middle sole, in making ordinary shoes for men and Women that will apparently add to the wearers height, That is, by means of the thick middle 'sole 'or Aby means of a thicker insole that is concealed, increased height is given to the wearer Without the cause thereof being revealed. For the insole or middle sole of increased thickness, I may either employ the insert construction I have shown, or I may use various types of insoles and middle soles that are rendered flexible by slashes extending transversely across the bottom of the middle sole or insole, such as straight line transverse slashes or zig-zag generally transverse slashes.
I may also employ a multiplicity of punches or perforations in the insole or middle sole, which punches or perforations will both increase the flexibility of that element as Well as lighten its Weight. Light Weight is important because of the increased thickness of the middle sole or insole.
My construction in which I use a resilient insert in the forepart as shown in the drawing and described herein is particularly desirable because I may then employ a very thick middle sole Without sacricing flexibility and comfort of the shoe. In fact the very thick insert such as I5 shown in Figure 1 is extremely comfortable since a considerable resilience is aiorded to the ball of the foot.
Generally speaking a shoe having a very thick middle sole would be uncomfortable because of its stiiness and hardness and these disadvantages are overcome by my present invention.
The lextremely thick resilient insert 22 such as l5 in Figure l and 22 in Figure 2 or 54 in Figure enablesme by reason of the openings therein such as the perforations and the grooves to obtain a considerable 'forced breathing or pumping action of air as Ythe insert is flexed and pressed in the act of walking.
Various modifications of my invention will suggest themselves to those skilled in the art. I accordingly desire that in construing the breadth of the appendedclaim, they shall not be limited to the specic details'shown 'and described in connection with the above explanation.
I claim: i
In a shoe of the class described, an upper, van insole having a centrally disposed Yopening in its forepart, a middle sole having va similar opening registering with said opening in said insole, said insole comprising a resilient material and having a binding about the peripheral edges thereof, said middle sole having a binding about the peripheral edges, a rubber-like insert disposed in said common opening in the forepart of said insole and middle .soley and a sock lining overlying said insole and covering said filler.
