- a shoe sole that is distinguished by being divided into two or more parts, essentially comprising, at least, an upper part that is fixed to the body of the shoe and a part lower, whose lower face determines the floor of the sole, that is, the surface that remains in contact with the ground, which is interchangeable thanks to the fact that it is attached in a removable way to the fixed part, advantageously allowing it to be changed for another or others. different, with different goals.
- the upper fixed part and the lower interchangeable part are joined together by means of a mechanical coupling system by dovetailing the lower face of the upper fixed part with the upper face of the lower interchangeable part.
- said coupling system is made up of a plurality of transverse channels, and complementary projections, with a dovetail-shaped section configuration, in which, as is known to the expert, they are wider in the lower part. distal than in the neck, so that the lower part can only be inserted laterally for coupling to the upper part by sliding the projections of the lower part through the channels created for its fastening on the lower face of the upper part.
- said coupling system also comprises a channel, and corresponding projection, for additional coupling in the front part (toe) and in the rear part (heel) of the sole, with a circular configuration similar to a "light bulb”. , to give greater support to these parts, as they are the most vulnerable parts at the time of stepping.
- said coupling system is made up of a plurality of transverse channels, and complementary projections, with a circular or “bulb” shaped section configuration.
- the opposite sides of each of the parts that comprise the sole have a closed partition such that, once said parts are coupled, the channels and projections of the coupling system are hidden and only a straight line can be seen at the joint. between both parties.
- some additional outer stops are included that fit into holes located in correspondence, to ensure the coupling between both parts of the sole.
- the sole also comprises an intermediate part that is also removably coupled between the fixed upper part and the interchangeable lower part of the sole, which allows its height to be increased.
- said intermediate part has coupling means on its upper face and on its lower face that complementarily fit with the coupling means on the lower face of the fixed upper part and with the means on the upper face of the lower part. interchangeable.
- Figures number 1-A and 1-B.- Show respective side elevation views of a first example of embodiment of the shoe sole with interchangeable sole, object of the invention, specifically an example with coupling based on channels in the form dovetail, where the lower interchangeable part is of a type with a higher relief floor in figure 1-A and another type with a smoother floor in figure 1-B.
- Figure number 2. Shows a side elevation view of another example of the sole of the invention, in this case an example, also with dovetail-shaped channels as a means of coupling between the two parts of the sole and with two additional coupling channels at the respective ends of the toe and heel.
- Figure number 3. Shows a perspective view of another example of the sole of the invention similar to the one shown in figure 2, represented with its two parts in a partially coupled position, showing their configuration, especially on the upper face. of the interchangeable lower part.
- Figure number 4.- Shows a top perspective view of another example of the fixed upper part of the sole of the invention, specifically an example with circular or bulb-shaped channels, as a coupling means of its lower face with the interchangeable bottom.
- Figure number 5. Shows a side elevational view of the upper part of the sole shown in figure 4, showing its closed side wall.
- FIGS number 6 and 7.- Show respective views, in top perspective and side elevation, respectively, of an example of the interchangeable lower part of the sole of the invention, with coupling means complementary to the fixed upper part shown in figures 4 and 5.
- Figure number 8.- Shows a bottom plan view of the fixed upper part and the lower interchangeable part of the sole of the invention, according to the example of said parts shown in figures 4 to 7, represented in the initial coupling phase.
- Figure number 9. Shows a perspective view of the sole of the invention, according to the example shown in figure 8, in this case represented with the two parts that it comprises once completely coupled.
- Figure number 10. Shows a perspective view of an example of the intermediate part that, optionally, comprises the sole of the invention, showing its configuration.
- figure number 11.- Shows a perspective view of an example of the sole of the invention that includes an intermediate part, represented with the three parts that it comprises in the coupling phase, showing the configuration of each of them.
- the sole (1) is divided into at least two parts, a fixed upper part (2), which is fixed to the body of the shoe (not shown) in a conventional manner, and a interchangeable lower part (3) that can be removably coupled to the fixed part, allowing it to be replaced by the same or a different one, either with a different type of floor (3a), defined by its lower face (figures 1-A and 1-B), and/or with a different height, and/or with a different structure to compensate for dysmetria problems, and/or with a different appearance, such as color, texture, and/or material.
- a fixed upper part (2) which is fixed to the body of the shoe (not shown) in a conventional manner
- a interchangeable lower part (3) that can be removably coupled to the fixed part, allowing it to be replaced by the same or a different one, either with a different type of floor (3a), defined by its lower face (figures 1-A and 1-B), and/or with a different height, and/or with a different structure to compensate for dys
- the upper fixed part (2) and the lower interchangeable part (3) are joined together by means of a mechanical coupling system by tongue-and-groove (4a, 4b) of the lower face of the upper fixed part (2) with the upper face of the interchangeable lower part (3).
- Figures 1 to 3 show how, in one embodiment, the coupling system is made up of a plurality of transverse channels (4a), and complementary projections (4b), with a dovetail-shaped section configuration, so that the lower interchangeable part (3) can only be inserted laterally for coupling to the fixed upper part (2).
