The bottom recess 62 is open at the back of the shoe and it extends from back to front along theheel base 61 and is closed at its front end. - The heel66 of this shoe ensemble has an
attachment segment 67 at the top with a trapezoidal cross-section complementary to that of the heel base recess 62. Theattachment segment 67 of the heel can be slidably inserted into recess 62 at the latter's back end and slid from back to front when the heel is to be attached to the shoe. - Near its front end the
heel base 61 presents a flat, vertical end face 68 (FIG. 13) extending up from its bottom surface. The heel carries a curved cantileveredspring 69 which snaps up into engagement with theend face 68 when the heel is fully inserted onto the shoe, as shown in FIG. 12, to lock the heel in place. When the heel is to be removed from the shoe, the user flexes the free end ofspring 69 down to disengage it from the front end face 68 ofheel base 61 and permit the slidable removal of the heel from the shoe in a front to back direction. Thus, thespring 68 acts as a detent for releasably locking the heel on the shoe when theattachment segment 67 of the heel is fully inserted into the recess 62 of the heel base on the shoe. - The heel cover166 (FIG. 15) in this shoe ensemble has an
attachment segment 167 at the top which is identical to theattachment segment 67 of heel 66 (FIG. 14) and is slidably insertable into and removable from the bottom recess 62 in the shoe'sheel base 61 in the same manner as the heel, as described. Below itsattachment segment 167 the heel cover is relatively thin vertically. The heel cover carries a leaf spring on its front end (not shown in FIG. 15) which is identical to thespring 69 on the front end of heel 66 and coacts with the front end face 68 of theheel base 61 in the manner described forspring 69, acting as a detent for releasably locking the heel cover on the shoe when theattachment segment 167 of the heel is fully inserted into the heel base recess 62 in the shoe. - With heel66 removed from the shoe and the
heel cover 166 attached to it, the shoe becomes a “flat” for casual wear in the same manner as the earlier described embodiments of the present shoe ensemble. - Fourth Embodiment—FIGS. 16 and 17
- FIGS. 16 and 17 show the shoe and heel components of a fourth embodiment of the shoe ensemble of the present invention. The heel cover in this embodiment is identical to the one shown in FIG. 5 and already described in detail.
- The shoe70 in FIGS. 16 and 17 is of substantially different design from the shoes in the preceding embodiments, indicating the versatility of this invention. The
heel base 72 on this shoe has a bottom recess identical to the one in the embodiment of FIGS. 1-6, and theheel 71 for this shoe has anattachment segment 73 at the top that is identical to theattachment segment 37 on the heel shown in FIG. 2. - The heel in FIGS. 16 and 17 and the heel cover for this shoe are individually attachable and removable from this shoe in the same manner as the corresponding components in the shoe ensemble of FIGS.1-6.
- Fifth Embodiment—FIGS.18-21
- In FIG. 18 the shoe ensemble has a
platform heel 80 releasably attached to aheel base 81 on the shoe just behind a flexible segment of the shoe bottom. As shown in FIG. 20, thebase 81 is formed with a very shallow, open-bottomed,cylindrical recess 83 and carries femalesnap fastener elements 84 at intervals around the periphery of this recess. - The
heel 80 has a thin,flat attachment piece 85 on top that is shaped and dimensioned substantially complementary to recess 83 so as to have a snug fit therein. Theattachment piece 85 on the heel carries malesnap fastener elements 86 on its periphery for snap-in, manually releasable, locking engagement with thefastener elements 84 on the base when the attachment piece is inserted into thebase recess 83. - The heel cover (FIG. 21) in this embodiment of the present shoe ensemble has a thin, flat attachment piece185 on the top which is identical in size, shape and function to the
attachment piece 85 ofheel 80. Male snap fastener elements 11186 on the periphery of attachment piece 185 have manually releasable locking engagements with the corresponding femalesnap fastener elements 84 on the heel base of the shoe. The remainder of the heel cover consists of athin layer 90 of rubber or other suitable material covering the bottom of attachment piece 185, so that the vertical dimension of the cover plate is small, enabling the shoe to assume a much more flattened shape (FIG. 19) on the wearer's foot than its shape when the platform heel is attached (FIG. 18).
