2 Claims. (o1; 36-1-36) My inventionrelates generally to shoe heels to the permanent heel portion l.
landhas particular reference to heels which are formed in two portions, detachably secured'together by interengaging members on the said portions."
.One object of my invention is to provide an improved means whereby the wearing portion of. the shoe heel can be quickly andeasily-detached and replaced by another wearing "portion without the use of nails, pegs or similardevices andwithout the necessity for the services ofa shoemaker. I v j I I further object of my invention is to zpro- .vide' a construction which is of simplified character, inexpensive to manufacture and easier 'to attach or detach than prior-constructions; 1 I have achieved'the.foregoingobjects, ,and such other objects as may hereinafter :appear or be'pointed out,'; in the manner illustratively exemplified in the accompanying drawing, wherein,
Figure 1 is a perspective view showing a shoe heel provided with attachment plates constructed in accordance with one embodiment of my invention.
Figure 2 is a perspective view showing a shoe heel provided with attachment plates constructed in accordance with another embodiment of my invention, and
Figure 3 is a perspective view showing a shoe heel provided with attachment plates constructed in accordance with still another embodiment of my invention.
The heel comprises a portion I which is permanently attached to the shoe and a detachable portion or lift 2. Permanently secured to each of these portions is a thin sheet metal attachment plate, these plates being designated in the drawing by the reference numerals 3 and 4. The plate 3 in accordance with my invention is secured to the permanent heel portion l by means of a single screw 5 and the plate 3 is provided with turned down flanges 6 in order to prevent rotation of the plate 3 with respect The flanges 6 incidentally provide a means for preventing the curling or peeling of the breasting lining 1. The plate 4 may be secured to the detachable heel portion 2 by nails 8 or other suitable fastening means.
In the embodiment of my invention illustrated in Figure l, the plates conform tothe heel and lift both in shape and in size. The plate 3 is provided with two integral flanges 9 bent up from the plate along the curved edge thereof and a the plate 3 in such-manner that the flanges 9 are permitted to enter the recesses ll with the forward straight edge l2 of the plate 4resting on the upper'edge 'of the flange I0. A slight pressure is 'then appliedto the parts in a direction to force single integral flange Ill be t upfrom the plate along the" forward straightredge thereof." The plate 4 is providedwith two recesses l I cut into the curvededge of the plate, the location, and
dimensions of these recesses being such thatthey 5 are adapted to receive with a snug fit the flanges Softhe plate 3.
A In order to attach the lift 2 of the heel to the main bodyportion I, .the plate 4 is engaged with the plates together, whereupon the flange I0, be- 15 ing resilient, will yield to permit the edge [2 of the plate-A to, snap into position with the adjacent faces; of: the plates inmutual contact. To facilitate the attachment of the plates,- the straight edge l2 of the plate 4 may be slightly beveled. Due to theinherent resiliency of the flanges 9 and ID the plates are locked together against accidental disconnection. However, should it be desired to remove the lift, all that is necessary is to insert the blade of a knife or a similar instrumentality between the plates to pry them apart. To facilitate this, the plate 4 may be provided with notches [3 along the edge 12.
In the embodiment of my invention illustrated in Figure 2 the plates are considerably smaller than the heel or heel lift and are trapezoidal in form, the side edges of the plates converging towards the rear of the heel. The plate 3 has its side edges l5 slightly turned up and spaced apart a short distance from the permanent heel portion l. Adjacent to its forward edge and between its side edges the plate 3 is provided with a hump Hi. The plate 4 is seated within a depression l1 formed in the heel lift and has inturned side flanges l8 which provide channels for receiving the side edges l5 of the plate 3. Preferably, the flanges I 8 taper from the forward edge of the plate to the rearward edge thereof. The plate 3 also has at its rear edge an inturned flange [9. In the plate 4, at a point between the side edges and at an appropriate distance from the forward straight edge an opening 20 is provided for receiving the hump IS on the plate 3 in order to prevent the accidental disconnection of the heel lift from the main body portion.
To connect the plates, the plate 4 is engaged with the plate 3 in such a manner that the rear portion of the plate 3 is disposed in advance of the forward edge of the plate 4. The plate 3 is now moved rearwardly over the plate 4 and the edges l5 of the plate 3 engage in the channels formed by the flanges l8 until the hump l6 clicks into the opening 20. The flange l9 serves as a stop to prevent further relative movement of the plates.
In the embodiment of my invention illustrated in Figure 3 the plates are generally of the same configuration as the plates of Figure 2 and the size with respect to the heel is in the same proportion as in Figure 2. The plate 3 is provided with an upstanding flange 2| at the forward edge thereof and a similar flange 22 at the rear edge thereof. formed in the lift and is provided with side flanges 24. In this form of my invention the flanges 2| and 22 of the plate 3 engage the for, ward and rear edges, respectively, of the plate 4,
while the side flanges 24 of the plate-4engage the corresponding side edges 25 of the plate 3. The
depression 23 is extended slightly beyond the rear edge of the plate 4 to leave-a narrow space 26 for the reception of the flange 22. To insure a firm gripping engagement between the flanges of each plate and the correspondingedges of the other plate, the flanges are slightly turned in as illustrated in Figure 3.
To attachthe plates, one is superimposed upon the other with the rear flange 22' of plate 3- engaged in the narrow' space 26v and with the for.-
ward edge of plate 4 restingupon the flange zl.
'A slight pressure is then applied to force the plates together whereupon the flanges 2i and 22 will yield to permit the plate 4 to snap into place. From the foregoing description it be evi- :dent that I have provided an improved means for detachably connecting a heel lift to the-main body portion of a heel, the constructionafiording security against accidental separation of the parts yet permitting easy and quick separation The plate 4 is seated in a depression 23 said :detachable portion.
when required. It will be observed that in the embodiments of Figures 2 and 3 the plates are concealed when the lift is attached to the main heel portion.
Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims, any modified forms of structure oruse of mechanical equivalents, which may be reasonably included within their scope.
Having thus described my invention and illustrated its use, what I claim as new and desire to ed to engage the respectiveside edges of the otherxplate, said, other-plate having end flanges adapted to en age the respective end edges of the said first mentioned. plate, the plate on the detachable portion being mounted in said depression and said depressicn being-equal to the combined thicknesses of said plates.
.1 2. A'heel for footwear comprising amain'body portion and a detachable portion, a plate permanentlyj secured to each. of'said portions and extending within threeedgesof'said portions, one of said plates having side flanges adapted to engage the respective. side edges of the other plate, said other plate having end flanges adapted to engage the respective end edges of the said first mentioned plate, the plate. secured tothe detachable portion being seated in a depression formed in JACK F.
