sHocK REsIsTING HEEL,
Filed Dec. l5, 1944 Patented Feb. 5, 1946 UNITED STATES PATENT OFFICE SHOCK RESISTING HEEL Villor P. Williams, Chicago, Ill. Application December 13, 1944, Serial No. 567,906
The invention relates to foot wear, particularly, a shoe heel. l
Y'Ihe invention has for its primary object the improvement of certain details of construction of the heel covered -by Patent #2,357,281, dated August 29, 1944. Some of the more specific objects of the invention are to provide an improved tread lift utilizing a resilient tongue' formed integral with the rim around the back and sides of the heel to provide an improved cushioning coaction and means for expelling entrance into the heel such as stones, grit, dirt, mud, snow or wet, etc., due to the groove formed integral with the tongue.
Another object of the invention is to provide a spring plate with a spring finger depending therefrom which can be incorporated within the conne of the cavity of the tread lift and thus render it a self-contained entity.
and more Another object of this invention is to provide a exible heel utilizing proper means to support the tongue, and to induce resilient coaction when the tongue is subjected to pressure in the act of walking.
The invention also consists of certain new'and original features of construction and combination of parts hereinafter set forth and claimed, although the novel features in the specification and in the claims hereinafter set forth when taken in connection with the accompanying drawing forming part thereof and which illustrates a present preferred form of the invention, in which Fig. 1 is a side elevation view of a shoe incorporating my improved resilient heel.
Fig.2 is a bottom plan view of the heel member proper, showing the groove formed around the tongue.
Fig. 3 is a sectional View on line 3 3 of Fig. 2 showing the spring iinger bearing against the rear side of the resilient tongue;
Fig. 4 is a bottom plan view of the base of the heel which in practice is attached to the outer sole of the shoe, with the spring plate fastened thereon, prior to attaching my resilient tread lift. y
Fig. 5 is a side elevational view of the spring plate with its spring linger depending therefrom, shown in Figs. 3 and 4.
Fig. 6 is a longitudinal cross section view of a modified form of my resilient tread lift with the spring Vplate fastened therein and with its spring ng'er set in the act of bearing against portion permanently attached to the outer sole of the shoe.
Fig. '7 is a sectional view of a further modified form of my resilient tread lift for heels utilizing a combination consisting of a flexible base or half `tread lift in cooperation with a leather lift cemented thereon within which my spring plate can be incorporated if so desired.
Fig. 8 is a detached cross section showing singularly the resilient base or half tread lift, shown in the combination illustrated in Fig. 7.
Referring more particularly to the drawing, wherein like reference characters designate like or corresponding parts throughout the different views, Fig. 1 designates a shoe I0 having an outer sole designatedgenerally I I, forming a part thereof and including a heel base attached to the outer sole designated I2. These parts are of conventional form and areshown merely to illustrate the application of the invention which will hereafter be described.
In Figs. 1 to 5 inclusive, the heel comprises a body or tread lift I3 of rubber or other suitable resilient or elastic material having a groove I4 formed to follow the contour of the `tongue and terminates at point I6 where the tongue merges into the body of the lift which automatically positions the hinging action intermediate said tongue and the confronting surface of the tread lift. As shown in the drawing, the body of the tread lift I3 and tongue I5 are molded in one piece. The rim I'I thus formed is of less height than the rearward extending portion I8 of the tongue I5. Said portion I8 curving in an upward direction and meeting the body lift at a point I9 which forms the groove I4. The curved portion I8 of the tongue I5 is molded relatively thin as at 20 to provide a freely collapsible, yet somel what restrained movement when the foot is put down in walking. This also provides a completely enclosed cavity 2I for the reception of a spring plate, if desired.
This point is substantially under the plantar tubercules of the os caleis. Groove I4 is formed partially to follow the contour of the tongue I5;
' it also tends to induce additional flexibility to the of thev adjoining leather base which is usually 55 cushioning coaction of the tongue, except atthe hinged portion I6, at which juncture, tongue I5 is merged into the rim portion I1 of the body of the tread lift Vand is subjected to a hinged action in the act of walking. Wall 20 of the tongue I5 is relatively thin, yet it is of sufficient thickness strength to serve as means for expelling entrance of stones, grit, mud, dirt, sand, snow or wet, etc., .that may accumulate within thegroove v heel having a resilient body associated with a material relatively harder than the resilient half lift of said heel.
7. The combination of a resilient tread lift for shoe heels formed integral with a depending tongue of curvilinear formation projecting rearwardly at 'an angle, the 4bottom surface of the tongue *being inclined upwardly and forwardly from the rear part of the rim to the front of the heel forming a recess in the rear surface thereof, a layer of leather lift rigidly fastened to the surface of the resilient tread lift, and a spring plate with a spring finger depending therefrom firmly held within the cavity of said lift, said spring finger bearing against the bottom surface of the tongue to provide a recoil action to said tongue when said tread lift and the adjoining element form a, perfect interlocking connection.
