DETAILED DESCRIPTION OF THE INVENTION

[0017] While this invention is susceptible to embodiment in many different forms, there is shown in the drawings and will herein be described in detail specific embodiments, with the understanding that the present disclosure of such embodiments is to be considered as an example of the principles and not intended to limit the invention to the specific embodiments shown and described. In the description below, like reference numerals are used to describe the same, similar or corresponding parts in the several views of the drawings. This detailed description defines the meaning of the terms used herein and specifically describes embodiments in order for those skilled in the art to practice the invention.

Definitions

[0018] The terms about and essentially mean10 percent.

[0019] The terms a or an, as used herein, are defined as one or as more than one. The term plurality, as used herein, is defined as two or as more than two. The term another, as used herein, is defined as at least a second or more. The terms including and/or having, as used herein, are defined as comprising (i.e., open language). The term coupled, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically.

[0020] The term comprising is not intended to limit inventions to only claiming the present invention with such comprising language. Any invention using the term comprising could be separated into one or more claims using consisting or consisting of claim language and is so intended.

[0021] Reference throughout this document to one embodiment, certain embodiments, and an embodiment or similar terms means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of such phrases or in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments without limitation.

[0022] The term or as used herein is to be interpreted as an inclusive or meaning any one or any combination. Therefore, A, B or C means any of the following: A; B; C; A and B; A and C; B and C; A, B and C. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

[0023] The drawings featured in the figures are for the purpose of illustrating certain convenient embodiments of the present invention, and are not to be considered as limitation thereto. Term means preceding a present participle of an operation indicates a desired function for which there is one or more embodiments, i.e., one or more methods, devices, or apparatuses for achieving the desired function and that one skilled in the art could select from these or their equivalent in view of the disclosure herein and use of the term means is not intended to be limiting.

[0024] As used herein the term rigid sole portion refers to a sandal sole made of a stiff, relatively inflexible, material such as wood or very stiff (very little flex during walking in the sandal) plastic. Materials such as leather, flexible plastics, such as found in flip-flop type sandals, and the like would not be included. Stiffness of the material can be achieved by making the sole thick. In one embodiment, the sole of the present invention is at least inch thick. The thickness also allows enough room to use a dowel of sufficient thickness to be utilized. In some embodiments, the rigid sole can be in multiple pieces or scored to flex without actual flexation of the sole itself such as taught in U.S. Pat. No. 2,466,580 (Dalbey), incorporated herein by reference. The sole top, in one embodiment, has slots for inserting the upper sandal portion, as shown in the Figures.

[0025] As used herein the term upper sandal portion refers to the flexible material used to wrap or place around the foot and hold the sandal on the foot. It is flexible to be able to wrap around the foot and shaped to hold the foot in place as do all sandals. It could be one, two, or more pieces. In the embodiment of the Figures, 2 pieces are shown. However, the upper sandal portion is designed to either be inserted in slots in the sole or attached to the edge of the sole in either case with dowels. In one embodiment, there are holes, as shown in the Figures, to allow the dowel to pass through the hole to hold the upper sandal portion in place. In addition, in one embodiment, glues and the like can also be utilized to further aid in holding the upper sandal portion on the sole. It can be made of any reasonably flexible material such as leather, plastic, or cloth. In one embodiment, there are laces, buckles, or the like to aid in holding the sandal on the foot.

[0026] As used herein the term rigid dowels refers to standard wooden, metal, composite (multiple materials, plastic, or other rigid peg (dowel) type device without a head for inserting into drilled holes in the side of the sole which, as shown in the Figures, hold the upper sandal portion in place. In one embodiment, the dowels are standard columnar dowels, as shown in the Figures, but could be any shape. In one embodiment, for every dowel on one side there is a matching one on the other side of the sole. In one embodiment, there are 3 dowels on each side of the sole. In other embodiments, there are from 2 to 6, 8, or 10 dowels.

[0027] As used herein the term dowel holes refers to holes drilled in the sides of the soles that will snugly fit the dowels sufficiently that the dowel will stay in place once pounded or inserted into the dowel hole.

[0028] As used herein the term attached refers to the upper sandal portion being fixed to the sole by inserting the plurality of dowels into a plurality of dowel holes in the sole side such that the dowel captures part of the upper sandal portion in the dowel holes. In one embodiment, the dowel passes through a hole in the upper sandal portion and holds it in place.

[0029] As used herein the term capture part of the upper sandal portion in the dowel holes refers to fixedly attaching the upper sandal portion to the sole utilizing dowels, as shown in the Figures, including the embodiment wherein the dowel passes through a hole in the upper sandal portion to hold it in place and the dowel fits snugly and will not fall out during normal use.

DRAWINGS

[0030] Now referring to the drawings, FIG. 1 is an exploded view of an embodiment of a shoe of the invention. In this view, rigid sole 1 has a thick sole 2 in which six dowels 3 (only three shown on one side, identical on other side) are positioned for insertion into dowel holes 5 on side 9 of the sole 1. In this embodiment, the top 7 of sole 2 has slots 8 (two toward the front and two toward the back of the top of the sole). In this view, the upper sandal portion 10 consists of front part 10a and back part 10b. The bottom edges 11 each have holes 12 in them. The bottom edges 11 are inserted into slots 8 and dowels 3 inserted into dowel holes 5 and aligned such that the dowels 3 pass through the dowel holes 5 holding the upper sandal portion in place. In this view, a shoelace 13 is also shown for aiding in holding the sandal on the foot of a user. In FIG. 2 we see the assembled sandal shown in FIG. 1.

[0031] In FIG. 3 we see a side perspective of a different embodiment of an assembled sandal. In this view, the sandal has the upper sandal portion 30a and 30b resting on the edge 32 of the sole of the sandal and attached via dowels 33 in that manner. In this view, we see the sandal on the foot 35 of a user.

[0032] Those skilled in the art to which the present invention pertains may make modifications resulting in other embodiments employing principles of the present invention without departing from its spirit or characteristics, particularly upon considering the foregoing teachings. Accordingly, the described embodiments are to be considered in all respects only as illustrative, and not restrictive, and the scope of the present invention is, therefore, indicated by the appended claims rather than by the foregoing description or drawings. Consequently, while the present invention has been described with reference to particular embodiments, modifications of structure, sequence, materials and the like apparent to those skilled in the art still fall within the scope of the invention as claimed by the applicant.
