' Application Maren 27, 195o, serial No. 152,253 1 4 claims. (01436-38) This invention relates to new and usef improvements and structural refinements in shoe heels, and the principal object of the invention is to provide a resilient shoe heel which is capable of storing a portion of the energy resulting from its impact with the ground or floor, so that the energy so stored may subsequently be expended when weight is being taken off the heel, thus permitting the pedestrian to walk in a cushioned, easy and comfortable manner.

Some of the advantages reside in its simplicity of construction, in its efficient operation, in its adaptability to economical manufacture and in the easy replaceability of its individual components when-worn.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the ivention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure l is an underside plan view of the invention,

Figure 2 is a rear elevational view thereof,

Figure 3 is a longitudinal sectional view, taken substantially in the plane of the line 3-3 in Figure 2,

Figure 4 is a horizontal sectional view, taken substantially in the plane of the line 4-4 in Figure 3,

Figure 5 is a horizontal sectional view, taken substantially in the plane of the line 5-5 in Figure 3, and

Figure 6 is a longitudinal sectional view, taken substantially in the plane of the line 6-6 in Figure 4.

Like characters of reference are employed to Referring now to the accompanying drawings in detail, the invention consists of a shoe heel which is designated generally by the reference character I6 and is secured in the usual location to the underside of the sole I2 of a shoe I4.

The heel I6 embodies in its construction a main body portion I6, preferably formed from solid rubber, or the like, this main body portion being rigidly secured to the sole I2 by a plurality of fastening elements or nails I8, substantially as shown.

The main body portion I6 is provided with a substantially rectangular recess 20 to accommo- ,qate a complemental body portion 22 which is also formed from solid rubber, or the like, the

complemental portion 22 extending rearwardly from the recess 26 and being substantially thinf ner than the main body portion I6 so that, in

effect, it is spaced downwardly from the sole I2; as is best shown in Figures 3 and 6.

The complemental body portion 22 is provided in its upper surface with a recess 24 to accommodate what may be called a lower plate 26 which is secured in the recess 24 by a plurality of fastening elements 28, so that the complemental body portion is reinforced against flexing while an upper plate 30 is firmly seated in a recess 32 provided in the upper surface of the main body portion I6, so that when the latter is secured to the sole I2, the upper plate 30 is securely retained in position.

The plates 26, 36 are provided with vertically spaced, channel- shaped seats 34, 36 respectively,-

for a coil spring 38 which extends transversely in the aforementioned recess 28 and has laterally angulated end portions 4I), 42. These end portions are anchored or seated in depressed and struck out portions 44, 46 respectively, provided on the respective plates 26, 30, the resiliency of the spring 38 being such as to urge the complemental body portion 22 to a position where the lower surface thereof is co-planar with the lower surface of the main body portion I6. However, when the rear portion of the heel is brought in contacty with the ground or floor, the complemental body portion 22 is swung to the position illustrated by the dotted lines 48. in Figure 6, this action placing the spring 38 under further tension and compressing the resilient shock absorber pad 54 and the energy stored in the spring and pad during this movement is subsequently available for returning the complemental body portion 22 to its initial or starting position.

The lower plate 26 is provided at the front end thereof with a pair of transverselv spaced, upwardly extending lugs 56 and a solid rubber block 52 is firmly secured between these lugs and is engageable with the underside of the top plate 30 y so, as to afford a terminal stop for the complemental body portion 22 when the latter is coplanar with the main body portion I 6. The compressible shock absorber pad 54 of resilient or the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

1. In a shoe heel, the combination of a main body portion provided with a recess. a complemental body portion disposed in said recess and extending rearwardly therefrom, a lower plate secured to the upper surface of the complementa] body portion and an upper plate adapted to` be secured to the underside of a shoe sole above said lower plate, and a coil spring mounted transversely between the upper and lower plates and affording a fulcrum for the complemental: body portion, whereby the latter may rock about a transverse horizontal axis, opposite ends of said spring being anchored to the respective upper and lower plates for urging said complementa] body portion to a position wherein the underside thereof is co-planar with the underside of said main body portion.

2. The device as defined in claim l together with a compressible resilient shock absorber pad secured between the upper surface of said complemental body portion and the underside of the stated shoe sole rearwardly of said' ful'crum.

3. The device as dened in claim 1 together with a resilient terminal stop pad mounted on said lower plate forwardly of said fulcrum and abutting the upper plate when the undersurfaces of the main and complemental body portions are substantially cao-planar.

4. The device as dened in claim 1 together with channel-shaped seats provided n said upper JOHN D. KELLS.
