DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-8, the present invention features a sandal system 100. The sandal system 100 of the present invention provides a means of constructing a variety of different types of sandals (e.g., colors, styles, etc.) from one standard base. Without wishing to limit the present invention to any theory or mechanism, it is believed that the sandal system 100 of the present invention is advantageous because it adds to the versatility of a sandal.
The sandal system 100 of the present invention comprises a base 110, which is similar to a sole of a standard sandal. Sandals and soles of sandals are well known to one of ordinary skill in the art. For example, the base 110 is generally elongated having a first side edge, a second side edge, a front edge, a back edge, a top surface, and a bottom surface. As shown in FIG. 1 and FIG. 2, the base 110 may be generally flat. As shown in FIG. 7 and FIG. 8, the base 110 may be curved to form a heeled shoe.
In some embodiments, a slot 130 is disposed in the base 110, for example a first end of the slot 130 is disposed at the front edge of the base 110. The second end 132 of the slot 130 may extend a certain distance into the base 110 (e.g., in the direction of the back edge of the base 110). In some embodiments, the slot 130 is between about 0.5 to 1.0 inches in length as measured from the first end to the second end 132. In some embodiments, the slot 130 is between about 1 to 2 inches in length as measured from the first end to the second end 132. In some embodiments, the slot 130 is between about 2 to 3 inches in length as measured from the first end to the second end 132. In some embodiments, the slot 130 is more than about 3 inches in length. In some embodiments, the second end 132 of the slot 130 is shaped like a hole (e.g., circular, cylindrical).
The base 110 may be constructed from a variety of materials, for example from a material comprising rubber, leather, wood, plastic, the like, or a combination thereof. The base 110 may be constructed in a variety of sizes, colors, and styles. For example, in some embodiments the base 110 is constructed in the form of a wedge shoe, a flat shoe, a platform shoe, and a heel (e.g., stiletto) (see FIG. 7, FIG. 8).
Disposed along the edges of the base 110 (or portions of the edges of the base 110), for example the first side edge, the second side edge, the front edge, and/or the back edge, is a track 140. The track 140 is adapted to receive one or more S-clips 150 (see FIG. 3). As shown in FIG. 3, a first end of the S-clip 150 hooks into the track 140. The second end of the S-clip 150 extends outwardly from the base 110.
The sandal system 100 of the present invention further comprises one or more interchangeable straps 210. The straps 210 may be constructed from a variety of materials. In some embodiments, the straps 210 are constructed from a material comprising leather, plastic, nylon, rubber, cotton, suede, the like, or a combination thereof.
Each strap 210 has a first end and a second end. In some embodiments, the first end of the strap 210 is attachable to the base 110 via a first attachment means (e.g., clip mechanism, hook mechanism, clasp mechanism). In some embodiments, the second end of the strap 210 is attachable to the base 110 via a second attachment means (e.g., clip mechanism, hook mechanism, clasp mechanism). In some embodiments, the strap 210 may be secured (e.g., hooked into) in other locations, for example in the slot 130 or in the S-clips 150 in the track 140. The strap 210 can be connected to the base 110 in any way that the user wishes. In some embodiments, the strap 210 rests across the front portion of the base 110, over or across the foot 101 of the user, behind the user's ankle, etc.
A user can construct a variety of different sandals by interchanging different straps and decorative pieces 610 (e.g., beads, chains, decorations such as flowers, triangles, etc.). This allows user to have numerous pairs of shoes (e.g., sandals).
Referring now to FIG. 7 and FIG. 8, in some embodiments, a heel shaft 410 (e.g., threaded screw) is disposed on (or attachable to) the bottom surface of the base 110. The heel shaft 410 functions to hold various decorative heel components 420, for example decorative heel components 420 can be threaded onto the heel shaft 410. Each decorative heel component 420 has a threaded channel 430 disposed therein for receiving the shaft 410. A heel lock 440 may be threaded onto the outer end of the heel shaft 410 for securing the decorative heel components 420 on the shaft 410.
The decorative heel components 420 may be constructed from a variety of materials including but not limited to wood, plastic (e.g., beads), metal, the like, or a combination thereof. The decorative heel components 420 may be constructed in a variety of shapes, for example triangular, circular (e.g., spherical), rectangular, the like, or a combination thereof. As shown in FIG. 7, the decorative heel components 420 include a generally square transparent piece 420a, a wooden triangular piece 420b, a plastic bead 420c, and a transparent rectangular piece 420d. The shaft 410 may be constructed in a variety of sizes for creating high or low heels.
In some embodiments, the sandal system 100 of the present invention is a kit comprising a base 110 and a plurality of interchangeable straps 210 (e.g., differently decorated straps). In some embodiments, the kit comprises between 2 and 5 interchangeable straps. In some embodiments, the kit comprises between 5 and 10 interchangeable straps. In some embodiments, the kit comprises more than 10 interchangeable straps.
In some embodiments, the kit further comprises one or more decorative pieces 610. For example, as shown in FIG. 6, the decorative piece 610 may be for enhancing the appearance of the sandal or the decorative piece 610 may function like the strap 210. In some embodiments, decorative pieces 610 are attached to one or more straps 210.
In some embodiments, the kit further comprises a heel shaft 410 and/or a heel lock 440. In some embodiments, the kit further comprises a plurality of decorative heel components 420.
