DETAIL DESCRIPTIONS OF THE INVENTION

(8) All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

(9) Referring to FIG. 1 through FIG. 7, the preferred embodiment of the present invention, the sandal with magnetically connected upper straps, is a sandal that enables a user to remove and replace the upper as desired. The term upper is used herein to refer to the straps of the sandal that are positioned over the user's foot and serve as retention members that keep the user's foot within the sandal. The present invention makes use of magnetic connectors to form detachable connections between the upper and the sandal's sole. This enables the user to modify the look or function of the sandal when necessary.

(10) Referring to FIG. 1, to achieve the above-described functionality, the present invention makes use of a multicomponent sandal with detachable parts. Specifically, the present invention comprises a multilayered sole 1, a plurality of strap-attachment couplers 2 and a removable upper 3. The sandal sole 1 is a unibody sole that provides comfort to the user and is designed to promote a desired aesthetic. Each of the plurality of strap-attachment couplers 2 is a receptacle that functions as a fastener which is used to form a detachable connection between the removable upper 3 and the sandal sole 1. To accomplish this, each of the plurality of strap-attachment couplers 2 comprises a connector-receiving receptacle 21 and an upper-fastening mechanism 22. The upper-fastening mechanism 22 is a fastener that connects to the removable upper 3. The removable upper 3 comprises a plurality of strap segments 31 and a plurality of connector inserts 32. The plurality of strap segments 31 is a collection of straps that is used to retain the user's foot within the sandal. The plurality of connector inserts 32 is a collection of fasteners that connect to the upper-connection mechanism. Preferably, the upper-fastening mechanism 22 is a magnet and each of the plurality of connector inserts 32 is composed of a ferromagnetic material so that each of the connector inserts can be magnetically coupled to a corresponding upper-fastening mechanism 22 from the plurality of strap-attachment couplers 2. In a preferred embodiment, each of the plurality of strap-attachment couplers 2 is a unibody receptacle that is integrated into the sandal sole 1, such that the opening of each of the plurality of strap-attachment couplers 2 traverses through a first face of the sandal sole 1. Preferably, each of the plurality of connector inserts 32 is designed as a unibody component. The unibody construction of the two components facilitates quickly coupling and decoupling the plurality of connector inserts 32 and the plurality of strap-attachment couplers 2.

(11) Referring to FIG. 1, FIG. 4, FIG. 5, the connection between the removable upper 3 and the sandal sole 1 is established by coupling each of the plurality of connector inserts 32 with a corresponding attachment coupler 25 from the plurality of strap-attachment couplers 2. To accomplish this, the plurality of strap-attachment couplers 2 is distributed across the first face of the sandal sole 1 so that the plurality of strap segments 31 can be retained in a configuration that facilitates maintaining the user's foot within the sandal, comfortably. Expounding on the arrangement of the plurality of strap-attachment couplers 2, the connector-receiving receptacle 21 traverses into the sandal sole 1, normal to the first face. As a result, the connector inserts do not protrude past the first face and are prevented from damaging the user's foot. The upper-fastening mechanism 22 is laterally positioned to the connector-receiving receptacle 21. Additionally, the upper-fastening mechanism is integrated into the sandal sole 1. Consequently, the upper-fastening mechanism 22 retains the connector insert within the connector-receiving receptacle 21 until the user disengages the connection.

(12) Referring to FIG. 1 and FIG. 5, the components of the removable upper 3 are arranged to facilitate providing a comfortable, function, and aesthetically pleasing sandal. To accomplish this, each of the plurality of connector inserts 32 is terminally connected to a corresponding strap 313 from the plurality of strap segments 31. Thus connected, each of the plurality of connector inserts 32 enables the corresponding strap 313 to be tethered to the sandal sole 1. Additionally, each of the plurality of connector inserts 32 is engaged within the connector-receiving receptacle 21 of a corresponding attachment coupler 25 from the plurality of strap-attachment couplers 2. Further, each of the plurality of connector inserts 32 is mechanically coupled to the upper-fastening mechanism 22 of the corresponding attachment coupler 25. As a result, the plurality of strap segments 31 is retained in a tethered configuration once the user inserts each of the plurality of connector inserts 32 into the corresponding coupler.

(13) Referring to FIG. 1, FIG. 4, and FIG. 5, the Present invention is designed to create a stable connection between the removable upper 3 and the plurality of strap-attachment couplers 2 that persists until the user choses to disengage the connection. To facilitate this, each of the strap-attachment couplers 2 further comprises a connector-securing plate 23 and a strap-securing slot 24. The connector-securing plate 23 is a rigid plate that is used to prevent vertical motion of the connector insert that is engaged within the connector-receiving receptacle 21 of the corresponding attachment coupler 25. The connector-securing plate 23 is adjacently connected to the upper-fastening mechanism 22. Additionally, the connector-securing plate 23 is integrated into the sandal sole 1, adjacent to the connector-receiving receptacle 21. Further, the connector-receiving plate is positioned overlapping an opening of the connector-receiving receptacle 21. Thus positioned, the connector-securing plate 23 obscures a portion of the opening of the connector-receiving receptacle 21, forming a barrier that prevents the connector insert from inadvertently sliding out of the connector-receiving receptacle 21. In addition to forming a physical barrier over a portion of the connector-receiving receptacle 21, the connector-securing plate 23 works in concert with the upper-fastening mechanism 22 to retain the connector insert in a desired position within the connector-receiving receptacle 21. To accomplish this, the upper-fastening mechanism 22 is positioned in between the connector-securing plate 23 and a base of the connector-receiving receptacle 21. As a result, the connector-securing plate 23 presses the connector insert against the base of the connector-receiving receptacle 21 when the connector insert is coupled to the upper-fastening mechanism 22. The strap-securing slot 24 traverses normally through the strap-securing plate. Additionally, the strap-securing slot 24 is positioned along a first lengthwise edge of the strap-securing plate. Furthermore, the strap-securing slot 24 is positioned coincident with the opening of the connector-receiving receptacle 21. As a result, the strap-securing slot 24 forms an opening that enables the corresponding strap 313 to slide into a position where pulling on the corresponding strap 313 causes the connector insert to press against the connector-securing plate 23. More specifically, the position of the strap-securing slot 24 causes the tension on the corresponding strap 313 that is caused by the user's foot to be directed normal to the connector-securing plate 23. This prevents the tension in the corresponding strap 313 from pulling the connector insert away from the upper-fastening mechanism 22, and thus decoupling the connector insert from the upper-fastening mechanism 22.

(14) Referring to FIG. 2, FIG. 4, and FIG. 5, as described above, in as alternative embodiment the sandal sole 1 is a multilayered sole. The multilayered sole 1 is composed of multiple layers of material that are sandwiched together to create a sole that is comfortable, functional, and aesthetically pleasing. Specifically, the multilayered sole 1 comprises an outsole 11, a fastener-mounting layer 12, a plate-mounting layer 13, and an insole 14. The fastener-mounting layer 12 is superimposed onto the outsole 11. Additionally, the upper-fastening mechanism 22 is integrated into the fastener-mounting layer 12. Consequently, the fastener-mounting layer 12 is maintained in a position that facilitates retaining the upper-fastening mechanism 22 in a position that facilitates attaching the removable upper 3 to the multilayered sole 1. The plate-mounting layer 13 is superimposed onto the fastener-mounting layer 12, opposite to the outsole 11. Additionally, the connector-securing plate 23 is integrated into the plate-mounting layer 13. Accordingly, the plate-mounting layer 13 is maintained in a position that facilitates retaining the connector-securing plate 23 in a position that facilitates maintaining the connection between the removable upper 3 to the multilayered sole 1. The insole 14 is superimposed onto the plate-mounting layer 13, opposite to the fastener-mounting layer 12. Additionally, the first face is positioned opposite to the plate-mounting layer 13 across the insole 14. As a result, the user's foot rests on the first face while wearing the present invention. Further, the fastener-mounting layer 12 and the plate-mounting layer 13 are sandwiched between the outsole 11 and the insole 14. Moreover, the user's foot applies pressure to the insole 14 which aids in securing each of the plurality of connector inserts 32 within the corresponding attachment coupler 25. The connector-receiving receptacle 21 traverses normally through the insole 14, the plate-mounting layer 13, and the fastener-mounting layer 12. Consequently, the connector-receiving receptacle 21 enables the user to insert the connector insert into the multilayered sole 1 while preventing the connector insert from completely passing through the multilayered sole 1.

(15) Referring to FIG. 1 and FIG. 4, the plurality of strap segments 31 is configured to create removable uppers 3 of varying shape and size. To facilitate this, each of the plurality of strap segments 31 comprises a first end 311 and a second end 312. Additionally, the first end 311 of each of the plurality of strap segments 31 is terminally connected to each other. As a result, the removable upper 3 can be constructed in configuration that include, but are not limited to, a Y-shaped thong, a single continuous band that is positioned over the user's foot, or a strap assembly that is positioned over the user's foot as well as wrapped around the user's heel. Each of the connector inserts is terminally connected the second end 312 of the corresponding strap 313 from the plurality of strap segments 31. Consequently, the second end 312 of the corresponding strap 313 is used to tether the removable upper 3 to the sandal sole 1 while the first end 311 is used to create the overall shape of the removable upper 3.

(16) Referring to FIG. 1, FIG. 4, and FIG. 6, each of the plurality of connector inserts 32 is designed to attach to the second end 312 of the corresponding strap 313 in a manner that facilitates attaching the removable upper 3 to the sandal sole 1. To achieve this, each of the plurality of connector inserts 32 comprises a first plate 321, a second plate 322, a central plate 323, a first strap channel 324, and a second strap channel 325. The first plate 321, the second plate 322, and the central plate 323 are rigid members that are mounted onto the second end 312 of the corresponding strap 313. To further describe the arrangement, the first plate 321 is adjacently connected to the central plate 323. Additionally, the second plate 322 is adjacently connected to the central plate 323, opposite to the first plate 321. As a result, the first plate 321, the second plate 322, and the central plate 323 form a block that is shaped to be engaged into the connector-receiving receptacle 21. The first strap channel 324 traverses through the first plate 321. Additionally, first strap channel 324 is positioned adjacent to the central plate 323. Similar to the first strap channel 324, the second strap channel 325 traverses through the second plate 322. Further, the second strap channel 325 is positioned adjacent to the central plate 323. Moreover, the first strap channel 324 is positioned parallel to the second strap channel 325. As a result, the first strap channel 324 and the second strap channel 325 enable the second end 312 of the corresponding strap 313 to pass through the first plate 321 and the second plate 322. Finally, the corresponding strap 313 is looped through the first strap channel 324 and the second strap channel 325, about the central plate 323. Thus positioned, the second end 312 of the corresponding strap 313 is anchored to the connector insert.

(17) Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
