Description:

The present invention relates to new and useful improvements in shoe heels, and has for Its primary object to provide, in a manner as hereinafter set forth, a cushion heel having novel pneumatic cushioning means.

Another object of the invention is to provide a shoe heel including a permanently attached lift, and a tread member detachably connected to said lift in a novel manner.

Another object of the invention is to provide a shoe heel embodying a construction and arrangement which is such as to assure maximum comfort and ease when standing or walking.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts through the several views Sand wherein: Figure 1 is a bottom plan view of the invention with the tread member omitted.

Figure 2 is a vertical sectional view through the invention.

Figure 3 is a top plan view of the tread member. 25 Referring now to the dralwing, numeral 5 designates a portion of a shoe to which a left member 6 is permanently attached. Embedded in the lift 6 is a metallic frame member 7 of substantially the shape shown in broken lines in Fig. 30 1. The frame member 7 has depending from its lower side a plurality of spaced sockets 8.

There are holes through the frame member 7 and sockets 8 through which nails 9 pass to fasten the lift 6 to the shoe 5.

35 The lift 6 has in its lower side a recess 10. A vent II for the recess 10 is provided in the lift 6 having its outlet in the front side or breast 12 of said lift 6. The vent I is held open at all times by a tube 13 provided with diametrically disposed ears 14 intermediate its ends embedded in the lift 6 holding said tube in place.

A tread member 15 has embedded therein a metallic frame member 16 of substantially the same shape as the frame member 7 in the lift $. 45 A plurality of spaced sharks I1 extend upwardly from the frame member 16 in the tread IS and terminate in heads 18 which are engageable in the sockets 8. Formed on the upper side of the tread member 15 is a dome shaped extension It open at the top as at 2W' and having an integral neck 21. In a vertical line with and situated below the dome 19 is a recess 22. A protuberance 22 is formed on the lower side of the tread member IS.

Prom the above it will be seen that the invention comprises a pneumatic cushion heel having a detachable tread portion of novel construction and operation. When the wearer of shoes equipped with the invention, places his foot on a supporting surface the protuberance 23 contacts the surface first and the weight of the wearer causes the protuberance 23 to flex and compress the air within the chamber formed by the recesses 16 and 22 and force it through the vent I.

The vent Il is of small diameter thus the air is released slowly thereby creating a cushioning effect. As the tread member 15 Is detachable the same may be changed from right to left foot as it wears or may be replaced by a new one when worn out. The dome shaped extension 19 and neck 10 21 contact and conform to the recess 10 in such a manner asto form a substantially air tight connection.

Although I have shown and described herein a preferred embodiment of my invention it is to 2g be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the material and in the structure and arrangement of the parts within the spirit of the invention as claimed. 25 What is claimed as new is: 1. A heel comprising a lift having a recess in its lower face, a resilient tread member including a raised portion engageable in the recess and conforming in shape thereto, said tread member and the raised portion thereof having a pneumatic chamber therein, a protuberance on the lower face of the tread member for flexing same and collapsing the chamber, said lift member having a vent therein for said chamber, a tube in said vent for holding same open, said tube including anchoring lugs embedded in said lift member, a frame embedded in said lift member, sockets on said frame, a frame embedded in said tread member and studs on the second named frame including heads engageable in said sockets for detachably securing the lift and tread member together.

2. A heel comprising a lift having a recess in its lower face, a resilient tread member including a raised portion engageable in the recess and 45 conforming in shape thereto, said tread member and the raised portion thereof having a pneumatic chamber therein, a vent for the chamber, a frame embedded in said lift member, sockets on said frame, a frame embedded in said tread 50 member and studs on the second named frame including heads engageable in said sockets for detachably securing the lift and tread members together.
