Abstract
An ergonomic footwear at least includes an outsole having a top surface including a datum plane and at least one contacting portion such configured that a difference in elevation is formed between the contacting portion and the datum plane, wherein the contacting portion is located at a place to which a force is applied by a treading human foot sole of a wearer. Accordingly, such structure can prevent the wearer's sole from sliding with respect to the outsole, thereby facilitating stable treading of the wearer's sole and further enhancing the wearer's walking smoothness.
Description
- 1. Technical Field
- The present invention relates to footwear, and more particularly to an ergonomic footwear for helping wearers walk with improved smoothness.
- 2. Description of Related Art
- Human walking is an arc-shaped motion achieved by using the hip joint as a pivot and the leg as a swinging arm and making the leg bent, lifted, and put on the ground. When treading against the ground, the human foot sole applies force from different regions as the treading motion proceeds. Therefore, the stableness of the treading process can have significant effect on the smoothness of the foregoing arc motion.
- Footwear manufacturers usually make outsoles from very flexible materials or form some spaced, transversely extending grooves at the bottom surface of the outsole in order to make the resultant outsoles more tensible, thereby improving the footwear in flexibility, for better conformity to the treading motion of the human foot sole, and further supporting wearers' walking smoothness. However, since the existing grooves are typically randomly distributed over the bottom surface of the outsole, the force-exerting regions may not necessarily act on the grooves when the wearers are treading. Thus the conventional footwear is ineffective in improving wearers' walking smoothness.
- The primary objective of the present invention is to provide an ergonomic footwear, which is helpful to preventing a human foot sole from sliding with respect to the outsole, thereby enhancing stability of treading of the human foot sole and further improving wearers' walking smoothness.
- Another objective of the present invention is to provide a footwear having improved outsole flexibility, so as to further improve wearers' walking smoothness. Still another objective of the present invention is to provide footwear that give support to a human foot sole at an inner arch, so as to make the human foot sole tread on the ground more stably.
- For achieving the foregoing objectives, according to the present invention, an ergonomic footwear primarily comprises an outsole that has an inner arch segment, an outer arch segment, a heel segment located behind the outer arch segment, a toe segment located before the outer arch segment and corresponding to human first, second, third, fourth, and fifth toes, and a metatarsus segment located between the outer arch segment and the toe segment, all corresponding to regions of a human foot sole, respectively, wherein the toe segment includes an inner toe segment and an outer toe segment, and the metatarsus segment includes an inner metatarsus segment and an outer metatarsus segment. The footwear is characterized in the outsole having a top surface, which includes a datum plane, and at least one contacting portion such configured that a difference in elevation is formed between the contacting portion and the datum plane. The contacting portion is located in at least one of the heel segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment. In the present invention, the contacting portion of the footwear different from the datum plane in the top surface of the outsole in elevation can prevent a walking wearer's foot sole from sliding with respect to the outsole, so as to make the wearer's foot sole tread more stably and further make the wearer walk more smoothly.
- In the ergonomic footwear provided by the present invention, the contacting portion of the outsole may be a top-surface depression depressed from the top surface of the outsole, or a top-surface bulge protruding from the top surface of the outsole.
- According to one embodiment of the ergonomic footwear of the present invention, the outsole has at least one bottom-surface recesses formed at a bottom surface thereof and corresponding to the top-surface depression or the top-surface bulge. Thereby, the disclosed footwear additionally has a cushioning function.
- Where the contacting portion of the outsole is a top-surface depression, the contacting portion is preferably located in at least one of the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, the outer toe segment, the outer arch segment, and the heel segment. Where the contacting portion of the outsole is a top-surface bulge, the contacting portion is preferably located in the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, the outer toe segment, the heel segment, and/or the inner and outer arch segments.
- The disclosed ergonomic footwear may further comprise a pad containing but not limited to a midsole, an insole or other thin lining deposited on the top surface of the outsole, or may comprise a midsole deposited on the top surface of the outsole and an insole deposited on the top surface of the midsole. The top surface of the midsole includes a datum plane and at least one contacting portion different from the datum plane in elevation. The contacting portion is located corresponding to at least one of the heel segment, the inner arch segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment of the outsole. In addition, the contacting portion of the midsole is preferably configured to match the contacting portion of the outsole. In one embodiment of the present invention, the contacting portion of the midsole may be a top-surface depression depressed from the top surface of the midsole, or a top-surface bulge protruding from the top surface of the midsole.
- The top surface of the insole has at least one hollow bowl or at least one hollow dome that is located corresponding to at least one of the heel segment, the inner arch segment, the outer arch segment, the metatarsus segment, the inner metatarsus segment, the outer metatarsus segment, the toe segment, the inner toe segment, and the outer toe segment of the outsole. The hollow bowl has a sagged surface integrally depressed from the top surface of the insole and a raised surface corresponding to the sagged surface and integrally raised from the bottom surface of the insole. The hollow dome has a raised surface integrally raised from the top surface of the insole and a sagged surface corresponding to the raised surface and integrally depressed from the bottom surface of the insole. Preferably, the insole has the hollow bowl and the hollow dome configured to match the contacting portion of the outsole.
- For example, where the contacting portion of the outsole is a top-surface depression, the contacting portion of the midsole is also a top-surface depression, while the insole has a hollow bowl. On the other hand, where the contacting portion of the outsole is a top-surface bulge, the contacting portion of the midsole is also a top-surface bulge, while the insole has a hollow dome.
- In addition, the raised surface of the hollow dome of the insole may have a reinforcing groove, and the sagged surface of the hollow bowl may have a reinforcing rib for preventing the hollow dome and the hollow bowl from deformation due to long time of use.
- In one embodiment of the ergonomic footwear of the present invention, the top surface of the outsole may have at least one top-surface trough near the at least one contacting portion. The top-surface trough is formed as starting from a place near a front periphery of the toe segment, proceeding between the inner and outer toe segments and going lengthwise toward the heel segment; or starting from a place near a periphery of the outer toe segment, proceeding between the toe segment and the metatarsus segment transversely, and reaching a place near a periphery of the inner toe segment; or starting from a place near a periphery of the outer metatarsus segment, proceeding between the metatarsus segment and the outer arch segment transversely, and reaching a place near a periphery of the inner metatarsus segment; and or starting from a place near a periphery of the heel segment, extending transversely along the heel segment to a place near an opposite periphery of the heel segment. The bottom surface of the outsole has at least one bottom-surface trough corresponding to the top-surface trough. This configuration can improve the flexibility of the outsole and further ensure the wearers' walking smoothness. In one embodiment of the ergonomic footwear of the present invention, the outsole may further have a protuberance protruding from the top surface of the outsole. The protuberance is located the inner arch segment for supporting the wear's foot sole at the inner arch, thereby facilitating stable tread of the wearer's sole and further enhancing the wearer's walking smoothness.

- Referring first to
FIG. 1 , according to a first embodiment of the present invention, anergonomic footwear 1 primarily comprises anoutsole 10. - The
outsole 10 is made of a PU foam material and possesses resilience. Of course, in practical manufacturing, theoutsole 10 may be made of any materials known to be used in making footwear outsoles, such as latex or thermoplastic rubber (TPR). As shown inFIG. 2 , theoutsole 10 may be divided, according to regions of a human foot sole that apply treading force, into an innerarch segment 19, an outerarch segment 11, aheel segment 12 that is located behind the outerarch segment 11, aninner toe segment 13 that is located in front of the outerarch segment 11 and corresponds to the human, anouter toe segment 14 that is located in front of the outerarch segment 11 and corresponds to the second through fourth toes, atoe segment 15 comprising the inner andouter toe segments metatarsus segment 16 that is located between the outerarch segment 11 and thetoe segment 15, and an inner andouter metatarsus segments metatarsus segment 16. In addition, as shown inFIG. 1 andFIG. 2 ,top surface 101 of theoutsole 10 includes a datum plane D and a plurality of contactingportions 102 that are configured to be different from the datum plane D in terms of elevation. In the embodiment shown inFIG. 1 , the contactingportions 102 are top-surface depression 102 a depressed downward from thetop surface 101 of theoutsole 10 and located in the outerarch segment 11, theheel segment 12, thetoe segment 15 and themetatarsus segment 16, respectively. Thus, when a wear wears the footwear and walks, force-exerting regions of his/her foot sole can sink into the top-surface depressions 102 a formed on theoutsole 10, and get secured from sliding with respect to theoutsole 10, thereby facilitating stable tread of the wearer's sole and further enhancing the wearer's walking smoothness. - Of course, in practical manufacturing, the top-
surface depression 102 a on theoutsole 10 are not limited to be formed in the outerarch segment 11,heel segment 12,toe segment 15, andmetatarsus segment 16 of theoutsole 10. They can be alternatively formed in the outerarch segment 11, theheel segment 12, theinner toe segment 13, theouter toe segment 14, theinner metatarsus segment 17 and theouter metatarsus segment 18 of theoutsole 10, as shown inFIG. 3 . Yet alternatively,such depression 102 a on the top surface of theoutsole 10 may be formed solely in any of the foregoing segments as needed. In addition, as shown inFIG. 4 andFIG. 5 , a plurality of bottom-surface recesses 104 may be formed on thebottom surface 103 of theoutsole 10. Each of the bottom-surface recesses 104 may be aligned with one said top-surface depression 102 a, so as to provide the disclosed footwear with additional cushioning effect. In a different aspect of the present invention, as shown inFIG. 6A , the contactingportions 102 on thetop surface 101 of theoutsole 10 may be protruding top-surface bulges 102 b located in the outerarch segment 11, theheel segment 12, theinner toe segment 13, theouter toe segment 14, thetoe segment 15, themetatarsus segment 16, theinner metatarsus segment 17, and theouter metatarsus segment 18, respectively. Particularly, as shown inFIG. 6B andFIG. 6C , in the case that the contactingportions 102 of theoutsole 10 are said top-surface depressions 102 a, they are preferably located in themetatarsus segment 16, theinner metatarsus segment 17, theouter metatarsus segment 18, thetoe segment 15, theinner toe segment 13 and theouter toe segment 14. In the case the contactingportions 102 of theoutsole 10 are said top-surface bulges 102 b, they are preferably located in theheel segment 12 and the outerarch segment 11. Of course, as shown inFIG. 6C , thebottom surface 103 of theoutsole 10 may be also provided with the bottom-surface recesses 104 corresponding to those top-surface bulges 102 b, so as to provide a footwear using theoutsole 10 as shown inFIG. 6C with cushioning effect. Alternatively, as shown inFIG. 7A andFIG. 7B , theoutsole 10 is substantially similar to theoutsole 10 shown inFIG. 3 except that thetop surface 101 of theoutsole 10 has a plurality of top-surface troughs 105 a˜105 d on bordering the contacting portions 102 (i.e. top-surface depressions 102 a) while thebottom surface 103 of theoutsole 10 has two bottom-surface troughs 106 corresponding to the top-surface troughs surface troughs 105 a˜105 b are each extending from an end near theouter toe segment 14, along thetoe segment 15 and themetatarsus segment 16, transversely to an end near theinner toe segment 13, and the bottom-surface troughs 106 are each extending from an end near theouter metatarsus segment 18, along themetatarsus segment 16 and the outerarch segment 11, transversely to an end near theinner metatarsus segment 17. The top-surface troughs 105 c starts from a point near a front periphery of thetoe segment 15 and goes lengthwise between the inner andouter toe segments heel segment 12. The top-surface trough 105 c′ starts from the top-surface trough 105 b and goes lengthwise along the outerarch segment 11 toward theheel segment 12. The top-surface trough 105 d extends from one end of theheel segment 12 transversely to an opposite end of theheel segment 12. Thereby, as shown inFIG. 8 , when a force F exerted by the wearer's treading down foot sole against theoutsole 10, theunaffected outsole 10 becomes theaffected outsole 10′. At this time, the bottom-surface trough 106 deforms into the expanded bottom-surface troughs 106′, and the top-surface trough 105 a deforms into the expanded top-surface troughs 105 a′. This configuration enhances the flexibility of theoutsole 10 and further improves the wearer's walking smoothness and comfort. In practical manufacturing, it is sufficient for thetop surface 101 of theoutsole 10 to have any one of the foregoing top-surface troughs 105 a˜105 d. - Then referring to
FIG. 9 , for realizing the spirit of creation as reflected by theoutsole 10 ofFIG. 7 , in a second embodiment of the present invention, afootwear 1 has anoutsole 20, which simply has two top-surface troughs 203 on itstop surface 201 and two bottom-surface troughs 207 on itsbottom surface 205 corresponding to the top-surface troughs 203. As these bottom-surface troughs outsole 20 of the second embodiment of the present invention, the bottom-surface troughs 207 and the top-surface troughs 203 also deform to provide theoutsole 20 with improved flexibility, thereby improving the wearer's walking smoothness and comfort. - Of course, in practical manufacturing, the bottom-surface troughs of the
outsole 20 may be configured as those shown inFIG. 10 . Particularly, the bottom surface of theoutsole 20 has a first bottom-surface trough 207 a, a second bottom-surface trough 207 b, a third bottom-surface trough 207 c and a fourth bottom-surface trough 207 d. Therein, the bottom-surface trough 2.07 a starts from an end near theouter toe segment 14 and proceed transversely between thetoe segment 15 and themetatarsus segment 16 to end at a place near theouter toe segment 14. The second bottom-surface trough 207 b corresponds to the first bottom-surface trough 207 a, and starts from one end near theinner toe segment 13 to extend transversely between thetoe segment 15 and themetatarsus segment 16 before stopping at a place near theinner toe segment 13. The third bottom-surface trough 207 c starts from one end near theouter metatarsus segment 18 to go between themetatarsus segment 16 and the outerarch segment 11 transversely, and reaches a place near theouter metatarsus segment 18. The fourth bottom-surface trough 207 d corresponds to the third bottom-surface trough 207 c by extending from one end near theinner metatarsus segment 17 along a transverse path between themetatarsus segment 16 and the outerarch segment 11 and ending at a place near theinner metatarsus segment 17. With this configuration, the present embodiment can also improve theoutsole 20 in flexibility. - Now referring to
FIG. 11 , in a third embodiment of the present invention, thefootwear 1 comprises theoutsole 10 and a pad which is amidsole 30 in this embodiment. Theoutsole 10 is configured according to the above embodiments and thus needs not to be discussed in any length herein. - The
midsole 30 is deposited on thetop surface 101 of theoutsole 10. As shown inFIG. 12 , thetop surface 301 of themidsole 30 includes a datum plane D, and a plurality of contactingportions 302 that are configured to be different from the datum plane D in terms of elevation. InFIG. 12 , the contactingportion 302 are top-surface depressions 302 a depressed downward from thetop surface 301 of themidsole 30 and located corresponding to the outerarch segment 11, theheel segment 12, thetoe segment 15 and themetatarsus segment 16 of theoutsole 10, respectively. Also, as shown inFIG. 11 , each of the top-surface depressions 302 a are corresponding to one said top-surface depression 102 a of theoutsole 10, respectively. Thus, when a wear wears the footwear and walks, force-exerting regions of his/her foot sole can sink into the top-surface depressions 302 a formed on themidsole 30, and get secured from sliding with respect to themidsole 30, thereby facilitating stable tread of the wearer's sole and further ensuring the wearer's smooth and comfort walk. - Of course, as stated in the in description of the first embodiment, in practical manufacturing, the top-
surface depressions 302 a of themidsole 30 are not limited to be formed on themidsole 30 at places corresponding to the outerarch segment 11, theheel segment 12, thetoe segment 15, and themetatarsus segment 16 of theoutsole 10. Instead, as shown inFIG. 13 , they can be formed to correspond to the outerarch segment 11, theheel segment 12, theinner toe segment 13, theouter toe segment 14, theinner metatarsus segment 17 and theouter metatarsus segment 18 of theoutsole 10, respectively. Alternatively, only one of the foregoing segments has the top-surface depression 302 a as needed. Yet alternatively, as shown inFIG. 14A , the contactingportions 302 of the midsoletop surface 301 may be top-surface bulges 302 b protruding from thetop surface 301 of themidsole 30, and correspond to the outerarch segment 11, theheel segment 12, theinner toe segment 13, theouter toe segment 14, thetoe segment 15, themetatarsus segment 16, theinner metatarsus segment 17, and theouter metatarsus segment 18 of theoutsole 10, respectively. Particularly, as shown inFIG. 14B , in the case where the contactingportions 302 of themidsole 30 are top-surface depressions 302 a, that are preferably arrange to correspond to themetatarsus segment 16, theinner metatarsus segment 17, theouter metatarsus segment 18, thetoe segment 15, theinner toe segment 13 and theouter toe segment 14 of theoutsole 10, respectively. In the case where the contactingportions 302 of themidsole 30 are top-surface bulges 302 b, they preferably correspond to theheel segment 12 and the outerarch segment 11 of theoutsole 10.
