BACKGROUND OF THE INVENTION

[0003] 1. Field of the Invention

[0004] The invention relates to shoes, more specifically to a mechanism wherein a low heel shoe converts into a stable shoe structure with a higher heel wherein the shoe's heel can be removed or replaced to change the style or comfort of the shoe.

[0005] 2. Discussion of the Background

[0006] It is well known that women enjoy the use of high-heeled shoes. High-heeled shoes represent a number of benefits for women, including style, increased height and improved posture. Women tend to feel more confident and poised when wearing high-heeled shoes. High-heeled shoes are considered to add style and elegance to a woman's outfit and are a staple of modern fashion.

[0007] Despite the many benefits, high-heeled shoes have proven detrimental to women's health. The use of heels is often painful, resulting in blisters, calluses and corns. Their use has also been linked to long-term problems such as foot pain, back pain, varicosity, edema, and infertility. High-heeled shoes concentrate the entire weight of the body on the ball of the foot, which often results in painful conditions such as metatarsalgia. When wearing high-heeled shoes, the shape of the foot conforms to a shape which counters the natural functionality of the foot, creating odd pressure points and often resulting in permanent damage. High-heeled shoes can create difficulties when walking, resulting in injuries such as sprained ankles.

[0008] For occasions that require that women dress elegantly and/or professionally, modern women tend to prefer the use of high-heeled shoes. However, it is possible that high-heeled shoes will not be suitable for certain moments of a particular day. For example, a woman may prefer high-heeled shoes for the office, in order to look elegant and professional during meetings or when receiving clients. However, if the same woman walks to work, the woman may prefer the use of flats or shoes with smaller heels to avoid a painful walk. In this case, the woman would have to use two separate pairs of shoes in the same day. This creates the inconvenience of having to carry the additional pair of shoes or having to keep additional pairs of shoes in different places. There is also the added cost of purchasing more than one pair of shoes.

[0009] Several shoes had been created to provide interchangeable heels, however most of the interchangeable shoes structures, more particularly in women shoes failed to provide an interchangeable stable structure easy to assemble without compromising the style.

[0010] Further a woman may also prefer to change the style of a particular shoe. For example, a woman may prefer "stiletto" type heels that match the color of the shoe's upper for a formal occasion. For a more casual occasion, a woman may prefer the same shoe, but with thicker, cork wedges. Also, a woman may prefer to use an all black shoe for the office, but may decide to add color to the outfit by changing to a colored heel for a social activity after work.

[0011] There is a need for shoes that can be adjusted for the changing needs of a woman during a particular day while providing a stable structure easy to assemble.

SUMMARY OF THE INVENTION

[0012] In light of the above shortcomings of the methods available to adjust the height of women's shoes, the present invention discloses a replaceable heel mechanism that is used to adjust the height of women's shoes. The mechanism comprises a shoe sole, a removable heel comprising a heel connector and an interchangeable heel, and a locking key to secure the removable heel to the shoe sole. The present invention is useful for adjusting the comfort or style of a particular pair of shoes during the course of a day.

[0013] Another object of the present invention is to provide a shoe that can be worn with or without the removable heel.

[0014] Another object of the present invention is to provide a mechanism wherein a removable heel can be easily attached or removed.

[0015] Another object of the present invention is to provide a more stable removable heel wherein the arrangement of part assists the shoe structure to withstand several unwanted movement.

[0016] Yet another object of the present invention is to provide a mechanism wherein a heel can be easily removed and replaced with a heel with different style.

DETAILED DESCRIPTION OF THE INVENTION

[0044] The present invention discloses the preferred embodiment of the invention wherein the embodiment can be made of different materials, wherein the material selection depends on the type of shoes, the weather in which the shoes will most likely be used, the size of the shoes and the cost.

[0045] FIG. 1A and FIG. 1B show the present invention as it is assembled. The present invention comprises a shoe sole 1, a removable heel R, a locking key 4 and a shoe upper 5. The removable heel R comprises a heel connector 2 and an interchangeable heel 3 wherein said removable heel is mechanically connected to said shoe sole 1 in order to convert a low heel shoe in to a high heel shoe. As illustrated in FIG. 1B the shoe upper 5 is attached to the shoe sole an it may be anything from a few thin straps to totally enclosing the foot.

[0046] FIG. 2 shows an isometric view of the assembled shoe sole 1. It has to be understood that the shoe upper 5 is not showed in order to clearly show the shoe sole 1. The shoe sole 1 comprises an adjustable platform on the bottom of the shoe. The platform comprises three separate flat sections, named foresole 11, midsole 12 and hindsole 13. The sections are mechanically attached and are fixed to the bottom of the shoe.

[0047] FIG. 3, FIG. 4 and FIG. 5 show the foresole 11 component of the preferred embodiment of the invention. The foresole 11 comprises a flat elongated component with at least one even edge 111. The foresole's even edge 111 comprises a fixing means to attach the part to another part that allows rotational motion. The fixing means of the preferred embodiment comprises several semi-circular protrusions 112 along the even edge 111, each comprising a hole 113. Several spaces 114 or clear areas having a pre-determinated are interpose between each semi-circular protrusion 112 in order to separates each semi-circular protrusion 112 from each other. The holes 113 at the semi-circular protrusions 112 are centrally aligned in order to be easily mechanically coupled to the midsole 12. The geometry of the remaining edges of the foresole 11 depends on the style of the shoe and the shoe upper 5. The foresole 11 supports the forefoot, which comprises the ball of the foot and the toes.

[0048] FIG. 6, FIG. 7 and FIG. 8 show different views of the midsole 12 of the preferred embodiment of the invention. The midsole 12 comprises a flat elongated body with a first short edge 121, second short edge 122 and a middle body, such as a rectangular component, which extends across the length of the shoe. The midsole 12 comprises a first short edge 121 and a second short edge 122, opposite to one another, and a middle body between said first short edge and said second short edge define by a first long edge 123 and a second long edge 124. In the instant case the angles between the first short edge 121 and the first long edge 123, the first long edge 123 and the second short edge 122, the second short edge 122 and the second long 124; and the second long edge 124 and the first short edge 121 are all right angles. The first short edge 121 and the second short edge 122 are equipped with a first short edge attaching mechanism and a second short edge attaching mechanism respectively to attach the midsole to another part allowing rotational motion at the midsole edges. Similar to foresole attaching mechanisms, the first short edge attaching mechanism and a second short edge attaching mechanism of the preferred embodiment comprises semi-circular protrusions 126 along their length, each semi-circular protrusion 126 comprising a hole 127. Several spaces 128 of a pre-determinated width separate each semi-circular protrusion 126 from the next semi-circular protrusion 126. The holes 127 in the semi-circular protrusions 126 are centrally aligned. The position of the semi-circular protrusions 126 of the first short edge 121 of the midsole 12 coincides with the spaces 114 between the semi-circular protrusions 112 of the foresole 11. The position of the semi-circular protrusions 126 of the second short edge 121 of the midsole 12 coincides with the position of the semi-circular protrusions 126 of the first short edge 121. The midsole 12 lies below the arch of the foot, and provides support to the midfoot. The width of the midsole 12 corresponds to the width of the foresole 11. The length of the midsole 12 depends on the style and size of the shoe.

[0049] Further the midsole 12 comprises a first attaching mean, such as a orifice 129, positioned at the middle body inside a groove. In the instant case the preferred embodiment of the orifice 129 comprises inner threads. The groove is deep enough to enclose the attaching mean avoiding it contact with the floor.

[0050] FIG. 9, FIG. 10 and FIG. 11 show different views of the hindsole 13 component of the preferred embodiment of the invention. The hindsole 13 elongated body comprises a foundation 131, a spacer 132 and a brim 133. The hindsole 13 supports the hindfoot, which comprises the heel of the foot.

[0051] The foundation 131 comprises a flat elongated component with at least one rounded edge 1311 and at least one foundation even edge 1312. The foundation 131 comprises a attaching means at said foundation even edge 1312 to attach the hindsole to another part, such as the midsole, allowing rotational motion at the mechanically connection between the hindsole and the midsole. The attaching means of the preferred embodiment comprises several semi-circular protrusions 1313 along the even edge 1312, each comprising a hole 1314. A space 1315 of the equal or greater width than the semi-circular protrusion 1313 separates each semi-circular protrusion 1313 from the next semi-circular protrusion 1313. The holes 1314 in the semi-circular protrusions 1313 are centrally aligned. The size and position of the semi-circular protrusions 1313 of the foundation 131 depends on the size and position of the semi-circular protrusions 126 of the second short edge 122 of the midsole 12. The position of the semi-circular protrusions 1313 of the even edge 1312 of the foundation 131 coincides with the spaces 128 between the semi-circular protrusions 126 of the second short edge 122 of the midsole 12. The semi-circular protrusions 1313 of the hindsole 13 must fit between the semi-circular protrusions 126 of the second short edge 122 of the midsole 12. The center of the holes 1313 of the semi-circular protrusions 13 must fit be aligned with the holes 127 of the semi-circular protrusions 126 of the midsole 12. Although the geometry of the foundation 131 may vary slightly depending on the style of the shoe, the shape of the foundation 131 will most likely comprise a semi-circular geometry.

[0052] Further the spacer 132 comprises a second flat component with geometry similar to the geometry of the foundation 131. Like the foundation 131, the spacer 132 comprises at least one spacer even edge 1321. The length, radius and overall dimensions of the spacer 132 is smaller than the dimensions of the foundation 131. The spacer 132 is integrally made or attached to the foundation 131 by a fixing means such as glue, nails, or screws and extends from the foundation 131 toward the brim 133.

[0053] The brim 133 comprises a third flat component with geometry similar to the geometry of the foundation 131. Like the foundation 131, the brim 133 comprises at least one brim even edge 1331. In the instant case the length, radius and overall dimensions of the brim 131 are smaller than the dimensions of the foundation 131, but greater that the dimensions of the spacer 132. The brim 133 is integrally made or attached to the spacer 132 by a fixing means such as glue, nails, or screws.

[0054] The foundation even edge 1312 of the foundation 131 is aligned with the spacer even edge 1321 and the brim even edge 1331. When assembled, the hindsole 13 comprises a part with at least one even edge, at least one rounded edge, several semi-circular protrusions 1313 and a groove created by the differences in dimension of the foundation 131, the spacer 132 and the brim 133.

[0055] The foresole even edge 111 is mechanically attached to a first short edge 121 of the midsole 12. The semi-circular protrusions 126 of the first short edge 121 of the midsole 12 are positioned in the spaces 114 between the semi-circular protrusions 112 of the foresole 11. The holes 113 of the semi-circular protrusions 112 of the foresole 11 are centrally aligned with the holes 127 of the semi-circular protrusions 126 of the first short edge 121 of the midsole 12. A first pin is inserted through the holes 113, 127, keeping the foresole 11 attached to the midsole 12. The foresole 11 and the midsole 12 is able to move with respect to one another about the axis of the first pin. Alternatively, the parts can be manufactured without the semi-circular protrusions 112, 126 and attached to each other by a fixing means such as hinges.

[0056] The foresole even edge 111 of the hindsole 13 is mechanically attached to a second short edge 121 of the midsole 12. The semi-circular protrusions 126 of the second short edge 122 of the midsole 12 is positioned in the spaces 1315 between the semi-circular protrusions of the foundation 131 of the hindsole 13. The holes 1314 of the semi-circular protrusions 1313 of the foundation 131 of the hindsole 13 is centrally aligned with the holes 127 of the semi-circular protrusions 126 of the second short edge 122 of the midsole 12. A second pin is inserted through the holes 1314, 127 of the semi-circular protrusions 1313, 126, keeping the hindsole 13 attached to the midsole 12. The hindsole 13 and the midsole 12 is able to move with respect to one another about the axis of the pin. Alternatively, the parts can be manufactured without the semi-circular protrusions 126, 1313 and attached to each other by a fixing means such as hinges.

[0057] When assembled, the shoe sole 1 comprises an elongated mechanism with two points of inflection. The upper side of the shoe sole 1 comprises the inner section of the shoe. The upper side of the shoe sole 1 is covered with a soft material in order to provide comfort for the user. The bottom side of the shoe sole 1 may be covered with a non-slip material, such as rubber.

[0058] FIG. 12, FIG. 13 and FIG. 14 show different views of the removable heel R, more particularly the heel connector 2 component of the preferred embodiment of the invention. The heel connector 2 comprises an elongated flat portion with a geometry that matches the geometry and dimensions of the hindsole 13. The heel connector 2 comprises at least one heel connector even edge 21, and at least one rounded heel connector edge 22. The heel connector 2 also comprises a raised rim 23 extending upwards throughout the entire perimeter of the geometry, with exception of the heel connector even edge 21. The raised rim 23 has an extended rim 24 facing the inner portion of the heel connector 2. The length of the extended rim 23 must be less than the difference between the brim 133 and the spacer 132 of the hindsole 13.

[0059] The extended rim 24 of the heel connector 2 slides between the foundation 131 and the brim 133 of the hindsole 13, keeping the hindsole 13 and the heel connector 2 attached to one another. Further the heel connector comprises a heel attaching mean 25.

[0060] FIG. 15, FIG. 16 and FIG. 17 show different views of the interchangeable heel 3 of the preferred embodiment of the invention. The interchangeable heel 3 comprises an elongated component comprising an angled proximal end 31 and a distal end 32. The geometry of the angled proximal end 31 of the interchangeable heel 3 resembles the geometry of the heel connector 2. The angle of the angled proximal end 31 depends on the difference in height between the foresole 11 and the hindsole 13, that is, the angle depends on the overall length of the interchangeable heel 3. The cross-sectional geometry of the interchangeable heel 3 can vary throughout the length, for example the elongated body may have a constant cross-sectional area throughout its length, or a variable cross-sectional area, with greater width at the angled proximal end 31 and a smaller geometry at the distal end 32. Other geometries can also be found, including wedges that extends all the way towards the foresole 11, covering the entire area below the shoe sole 1. Each interchangeable heel 3 comprises a hole 34 at a pre-determinated position wherein said position is directly related to the position of the orifice 129 in the midsole 12, wherein said orifice 129 coincides with the height of the hole 34 in the interchangeable heel 3.

[0061] Further the interchangeable heel 3 comprises a hole 33 aligned in accordance with the heel attaching mean 25. The hole 33 on the interchangeable heel 3 comprises an inner thread placed in a position such that the holes 25, 33 such as a screw 35 is inserted through the hole 25 in the heel connector 2 and is held in place by the inner thread in the hole 33 in the interchangeable heel 3, holding the heel connector 2 and the interchangeable heel 3 in place. An example of the screw 35 is shown in FIG. 18. FIG. 19 shows an isometric view of the assembly for the removable heel R composed by the heel connector 2 and the interchangeable heel 3.

[0062] FIG. 20, FIG. 21, FIG. 22 and FIG. 23 show different views of the locking key 4 component of the preferred embodiment of the invention. The locking key 4 mechanically attaches the interchangeable heel 3 to the midsole 12 wherein said locking key comprises an elongated body with a first locking key attachment, such as a bolt with a first threaded distal end 47. The locking key 4 is meant to be inserted into the hole 34 of the interchangeable heel 3 and fix inside the orifice 129 of the midsole 12. The locking key 4 further comprises a second threaded distal end 46, wherein said second threaded distal end is fixed at said interchangeable heel 3. Providing two threaded distal ends at said locking key 4 assists with the assembling process of the interchangeable heel 3 for a stable structure. It is important to understand that a nut may be included in a first recess 48 at the interchangeable heel 3, as shown in FIG. 24, wherein said recess support a nut which is fixed to said interchangeable heel. The shape of the recess 48 assists with the assembling process by holding the nut 44 in position.

[0063] When in use, the bottom surface of the foresole 11 rests flat above the floor. The midsole 12 is attached to the foresole 11 and is positioned at an angle with respect to the floor. The angle between the floor and the midsole 12 depends on the height of the interchangeable heel 3. The hindsole 13 is attached to the midsole 12, and is also positioned at an angle with respect to the floor. The angle between the hindsole 13 and the floor is less than the angle between the midsole 12 and the floor. The heel connector 2 and the interchangeable heel 3 are attached by a fixing means, such as a screw 34. The heel connector 2 slides into the groove between the foundation 131 and the brim 133 of the hindsole 13. When correctly assembled, the distal end 32 of the interchangeable heel 3 comes into contact with the floor.

[0064] The locking key 4 is positioned in parallel with respect to a line that connects the distal end 32 of the interchangeable heel 3 and the foresole 11. When in use, the bottom surface of the foresole 11 and the distal end 32 of the interchangeable heel 3 comes into contact with the floor. The user inserts her feet into the shoe, with the ball of the foot resting on the upper surface of the foresole 11 and the heels resting on the upper surface of the hindsole 13. The user's weight is distributed between the ball of the foot and the interchangeable heel. The position of the locking key 4 lies between both pressure points and distributes the user's weight more evenly among the different areas of the shoe.

[0065] The heel connector 2 principally restricts vertical movement between the shoe sole 1 and the interchangeable heel 3. The locking key 4 principally restrict horizontal motion between the interchangeable heel 3 and the shoe sole 1, completing the structure. However due to the positioning of the locking key with respect to the heel connector a more stable structure is acquired. For example, as shown in FIG. 25, the resulting force due to the person's weight wearing the removable heel 3 is distributed over the whole structure providing a more stable structure. The triangular shape created due to the arrangement of parts, such as having at least approximately a 90 degrees angle between the interchangeable heel 3 and the midsole 12 increases the supporting force of the shoe structure when using a removable heel R. Further the locking key 4 avoids the unwanted rotational motion of the interchangeable heel 3 and simultaneously the unwanted distance displacement of the midsole 12 with respect to the interchangeable heel 3. The present structure arrangement provides a stronger support for the ankle due to the connection, more particularly to the connection of the interchangeable heel 3 with the midsole 12.

[0066] Alternatively, the shoe can be worn without the heel connector 2 or the interchangeable heel 3. The locking key 4 is removed and the heel connector 2 slides from behind the hindsole 13. The attacing means that attach the foresole 11 to the midsole 12 and the midsole 12 to the hindsole 13 allows the rotational motion of each part, therefore the angles between the foresole 11 and the midsole 12 and the midsole 12 and the hindsole 13 can be adjusted. The shoe sole 1 is adjusted such that the brim 133 of the hindsole 13 comes into contact with the floor.

[0067] The interchangeable heel 3 may vary is style and shape different style with an easy assembling procedure such as removing or disconnecting the heel connector attaching mean 25 from the heel attaching mean 33. The screw 35 is removed, separating the interchangeable heel 3 from the heel connector 2. A different interchangeable heel 3 is attached to the heel connector 2 and the screw 35 is replaced. The heel connector 2 slides onto the hindsole 13, and the locking key 4 is inserted through the hole 34 of the interchangeable heel and into the orifice 129 of the midsole 12 to complete the structure.

[0068] Further the interchangeable heel 3 can be replaced with a interchangeable heel 3 with a different height. For this feature, the midsole 12 must comprise more than one orifice 129 and additional locking keys 4 with different lengths will be needed. The position of each orifice 129 depends on the height of the interchangeable heel 3. The screw 35 is removed, separating the interchangeable heel 3 from the heel connector 2. A different interchangeable heel 3 is attached to the heel connector 2 and the screw 35 is replaced. The heel connector 2 slides onto the hindsole 13, and the locking key 4 is inserted through the hole 34 of the interchangeable heel 2 and into the correct orifice 129 of the midsole 12 to complete the structure. When inserted into the correct orifice 129, the locking key 4 will be positioned parallel to the floor.

[0069] The shoe upper comprises all materials above the shoe sole. The shoe upper depends on the style of the shoe. The shoe upper can comprise straps to attach the show sole to the foot, or can comprise a more elaborated covering to protect the foot. The material used for the upper can also vary depending on the style of the shoe and the weather it is used in.
