Adjustable high heel

Abstract

An adjustable height shoe can include a shoe shank member extending between a heel end to a toe end of the shoe. A heel member can be removably attachable, at an attachment end thereof, to the shoe shank member. The attachment end of the heel member is insertable into the shoe shank member in a first direction to create a first shoe configuration and the attachment end of the heel member is insertable into the shoe shank member in a second direction to create a second shoe configuration. The shoe can further include a shoe shank member hole and one or more heel member holes that can align with each other when the attachment end of the heel member is inserted into the shoe shank member. A connector can fit into the aligned holes to maintain a connection between the shoe shank member and the heel member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(14) Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

(15) Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

(16) Referring now to FIGS. 1 through 12, a shoe 10, 20 can include a shoe shank member 12 extending between a heel end 34 to a toe end 30 of the shoe. A heel member 14, which includes an attachment end 24 and a base end 42 opposite the attachment end 24 (see FIGS. 1, 2 and 8), can be removably attachable, at [an] the attachment end 24 thereof, to the shoe shank member 12. A connector 50, as described in greater detail below, can help fix the heel member 14 with the shoe shank member 12 in a desired position. The adjustability of the shoe 10, 20 is performed with these three membersthe shoe shank member 12, the heel member 14 and the connector 50. Further, these three members are in use when the shoe is adjusted into any of the two or more heel heights. Thus, to adjust to a different heel height, the shoe 10, 20 uses the parts of the shoe at the original height. In other words, there are no additional parts to carry or replace. Instead, the parts are rearranged to provide the varying shoe heights.

(17) The attachment end 24 of the heel member 14 is insertable into the shoe shank member 12 in a first direction from a first side 32 to create a first shoe configuration, as shown in FIG. 1. The attachment end 24 of the heel member 14 is insertable into the shoe shank member 12 in a second direction from a second side 40 to create a second shoe configuration, as shown in FIG. 2. The first shoe configuration may have a lower heel height 16 (see FIG. 1), where the heel height 16 is measured from the top of the shoe shank member 12, where the user's heel would rest when worn, to the base of the heel member 14.

(18) In some embodiments, the heel member 14 includes two or more attachment locations along the attachment end 24 thereof, providing two or more heel heights in at least one of the first shoe configuration and the second shoe configuration. For example, a shoe shank member hole 36 can be formed through the shoe shank member 12 and one or more heel member holes 26 can be formed through the heel member 14. The shoe shank member hole 36 can align with one of the one or more heel member holes 26 when the attachment end 24 of the heel member 14 is inserted into the shoe shank member 12. The connector 50 can fit into the shoe shank member hole 36 and one of the one or more heel member holes 26 to maintain a connection between the shoe shank member 12 and the heel member 14. In some embodiments, the connector 50 includes an enlarged head 54 with a shaft 52 that extends therefrom, the shaft 52 being operable to extend through both the shoe shank member hole 36 and one of the one or more heel member holes 26. The enlarged head 54 can prevent the connector 50 from falling out as the connector is inserted from above the shoe shank member 12. In some embodiments, the enlarged head may be larger than the size of the shoe shank member hole 36. In some embodiments, the shoe shank member hole 36 can include an outer recessed portion (not shown) so that the enlarged head 54 can fit into the outer recessed portion without passing entirely through the shoe shank member hole 36. In this embodiment, the top surface of the enlarged head 54 may be flush or nearly flush with the top surface of the shoe shank member 12.

(19) In some embodiments, rails 28 may extend on opposing sides from a bottom side 23 of the shoe shank member 12. In some embodiments, first and second opposing shoulders 22 can be disposed along sides of a portion of the bottom side 23 of the shoe shank member 12. In some embodiments, the opposing shoulders 22 extend inward from each of the rails 28 along a portion thereof. The opposing shoulders 22 can be operable to receive the attachment end 24 of the heel member 14 therein. The opposing shoulders 22 can include an upper surface 48 mating with a lower surface 46 of the attachment end 24 of the heel member 14. In some embodiments, a sloped ramp 38 may be provided on the bottom side 23 of the shoe shank member 12, where the sloped ramp 38 can extend forward and rearward of the opposing shoulders 22 in a longitudinal direction of the shoe shank member 12. In some embodiments, the opposing shoulders 22 can be located centrally along a length of the bottom of the shoe shank member 12. Once assembled, for example, in the higher heel configuration of FIG. 2, the top side of the heel member 14 can press against a portion 18 of the sloped ramp 38 to provide additional support between the shoe shank member 12 and the heel member 14.

(20) In some embodiments, an insertion stop 44 can be disposed adjacent the attachment end 24. The insertion stop 44 can provide a maximum insertion of the attachment end 24 into the shoe shank member 12.

(21) As shown in FIGS. 11 and 12, the heel member 14 can include multiple heel member holes 26, where, by using an inner one of the heel member holes 26, the heel height of the shoe may be further decreased. Thus, a single shoe may provide two, three, or more height adjustment positions. While two heel member holes 26 are illustrated, additional heel member holes may be provided, such as three or four holes, for example, equally spaced along the attachment end 24 of the heel member 14.

(22) While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, the connector may be formed in various shapes or may be integrally formed with the shoe shank member, such as attached thereto with a living hinge and movable between an engaged and disengaged position. Further, the insertion stop may be present or absent and may include, where the heel member includes multiple height adjustment holes, a retractable pin that the user may retract to permit different sizes of adjustment. Further, while multiple holes are shown as an option for the heel member, similar multiple holes may be formed in the shoe shank member, providing even more ability to adjust the shoe to a desired height. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
