  • a “heel cover” used in the present invention is defined as a portion fitted at least to a heel section of a shoe to cover the heel section and can, of course, also be configured to cover a portion other than the heel section.
  • the “heel cover” according to the present invention can be expressed, for example, as a sole cover and an outsole cover.
  • FIG. 1 shows the state in which a shoe heel cover 1 according to Example 1 is fitted to a heel section S 1 of a shoe S
  • FIG. 2 shows a schematic configuration of the shoe heel cover 1 according to Example 1.
  • the shoe heel cover 1 according to Example 1 is so presented by way of example as to be used as part of a shoe S used by men and having a semi-cylindrical heel section S 1 having a curved portion facing rearward.
  • the shoe heel cover 1 according to Example 1 has a semi-cylindrical shape roughly similar to the shape of the heel section S 1 of the shoe S and includes a fitting section 11 detachably fitted to the semi-cylindrical heel section S 1 of the shoe S formed of a shoe body S 0 and the heel section S 1 , as shown in FIG. 1 .
  • the shape of the heel cover 1 is not limited to the shape roughly similar to the shape of the heel section S 1 of the shoe S, and a difference to some extent from the shape of the heel section S 1 of the shoe S can be absorbed as long as the shape of the heel cover 1 has an adequate elastic deformation capability.
  • the heel cover 1 includes an inwardly protruding, flange-shaped latching section 12 , which is provided on the rear side of the fitting section 11 and along the right and left upper end edges thereof and latches to a stepped portion formed between the shoe body S 0 and the heel section S 1 (the stepped portion is an upward facing surface of a portion formed around the heel section S 1 and jutting outward beyond the side surface of the shoe body S 0 ), as shown in FIGS. 1 and 2 . That is, the latching section 12 has an L-letter-shaped cross section or a hook-shaped cross section that bends inward so that the latching section 12 latches to the stepped portion.
  • the side surface of the fitting section 11 is preferably made of wall-shaped rubber (synthetic rubber) or resin (synthetic resin) for tight fastening, and fastening the heel section S 1 with the side surface allows an increase in the joining strength at which the heel cover 1 joins to the heel section S 1 . That is, the inner circumferential length of the fitting section 11 is so set as to be shorter than the outer circumferential length of the heel section S 1 . Therefore, to attach the heel cover 1 to the shoe S, the heel cover 1 is fitted to the heel section S 1 with the fitting section 11 stretched with a hand.
  • the entire heel cover 1 is made of synthetic rubber, synthetic resin, or any other similar material, as described above.
  • the upper side of the heel cover 1 that is the side where the fitting section 11 is provided is, however, made of readily stretchable synthetic rubber or synthetic resin that allows the heel cover 1 to be attached to the heel section S 1 of shoes S having sizes different from one another to some extent.
  • Silicon rubber for example, is preferably used as an example of the readily stretchable synthetic rubber.
  • An outsole section that is a lower portion of the heel cover 1 is preferably made of harder synthetic rubber or synthetic resin so that the outsole portion is unlikely to wear.
  • the material of the outsole section, which is the lower portion of the heel cover 1 can be a material typically used to form a sole. Further, rivets, spikes, or any other component can be placed on the outsole section, which is the lower portion of the heel cover 1 , to allow the shoe to be used on a rough road, a snowy road, and a muddy road.
  • the upper and lower portions of the heel cover 1 may, of course, be made of the same material. Using the same material allows the entire heel cover 1 to be produced in a single injection molding process.
  • the bottom surface of the fitting section 11 (inner surface facing upward when heel cover is attached to shoe) includes a plurality of suckers 13 facing upward to increase the adhesion between the bottom surface of the fitting section 11 and the heel section S 1 , as shown in FIGS. 2 and 3 .
  • the bottom surface of the fitting section 11 may instead include one large sucker 13 facing upward.
  • a single sucker or a plurality of suckers can be placed on the side surface of the fitting section 11 .
  • Standing edge portions drawn in the dotted lines in FIG. 3 can also be provided around each of the suckers 13 .
  • a tongue-shaped section 21 protrudes frontward from an upper portion of the front side surface of the fitting section 11 of the heel cover 1 , as shown in FIG.
  • the tongue-shaped section 21 can instead be placed at an upper portion of the rear side surface of the fitting section 11 .
  • FIGS. ( 4 a ) to 4 ( c ) show schematic configurations of part of the side surface of the fitting section.
  • the left side shows a front view
  • the right side shows a cross-sectional view.
  • suckers 14 . . . each having an inverted scale of a fish and oriented inward, such as those shown in FIG. 4( c ) , can be provided on the side surface of the fitting section 11 .
  • each having an inverted scale of a fish each form a scale-shaped (wedge-shaped) protrusion having a base portion facing downward, and a semispherical recess (sucking section) is provided in the vicinity of the center of the surface of the protrusion, whereby the fitting section 11 can be relatively smoothly fitted to the heel section S 1 .
  • the shape of the protrusions as well as the sucking force produced by the suckers causes the fitting section 11 to be unlikely to be detached from the heel section S 1 .
  • a double-sided tape with no suckers 13 can be glued onto the bottom surface of the fitting section 11 , or a double-sided tape can be added and glued onto a central portion of the upper surface of each of the suckers 13 . Still instead, a double-sided tape can be glued onto a region around each of the suckers 13 (region between adjacent suckers 13 ).
  • the double-sided tape may be replaced, for example, with an adhesive.
  • an adhesive an advantage of an increase in the joining strength is provided, whereas the attached adhesive needs to be carefully removed, for example, when a worn heel cover 1 is exchanged.
  • viscous, sticky silicon gel used in many cases, for example, to fix furniture in preparation of earthquakes can be used.
  • a metal plate may be glued onto one of the bottom surface of the fitting section 11 and the heel section S 1 , and a magnet may be glued to the other to form a magnetic joint. Further, magnets can be placed on both the fitting section 11 and the heel section S 1 . Using magnetic force as described above allows not only an increase in the joining strength at which the heel section S 1 joins to the heel cover 1 but easy exchange of a worn heel cover 1 .
  • Example 1 Workings and effects provide by Example 1 will next be described in the form of a list.
  • the shoe heel cover 1 according to Example 1 includes the fitting section 11 detachably fitted to the heel section S 1 of the shoe S formed of the shoe body S 0 and the heel section S 1 .
  • the heel cover 1 which can be readily detached, can be readily temporarily detected, for example, when the wearer visits a customer and desires to make the exterior appearance of the shoes particularly beautiful.
  • the heel cover 1 can prevent wear and damage of the side surface of the heel section S 1 .
  • the heel cover 1 can be attached to a shoe S to be discarded because the outsole section of the heel section S 1 of the shoe S has worn, whereby the shoe S can be reproduced.
  • the life of the shoe S can be further prolonged by exchanging the heel cover 1 before it is so worn that the shoe sole is reached. That is, since the outsole section of the heel section S 1 does not wear, replacing a worn heel cover 1 with a new heel cover 1 can semi-permanently prevent wear of the outsole section of the heel section S 1 .
  • the heel cover 1 is made of an inexpensive material and has a simple shape suitable for volume production, the heel cover 1 is very inexpensive as compared with a case where the shoe S is repaired.
  • the heel cover 1 includes the latching section 12 , which latches to the stepped portion formed between the shoe body S 0 and the heel section S 1 .
  • the latching force produced by the latching section 12 and acting on the stepped portion therefore allows the heel cover 1 to be unlikely to be detached from the heel section S 1 . That is, since the heel cover 1 is made of a stretchable material, latching the latching section 12 to the stepped portion with the heel cover 1 stretched can prevent the heel cover 1 from being detached.
  • the bottom surface (inner surface facing upward) of the fitting section 11 includes one or more suckers 13 .
  • the sucking force produced by the suckers 13 allows the heel cover 1 to be unlikely to be detached from the heel section S 1 . Further, since force in the direction in which the suckers 13 are pushed repeatedly acts on the suckers 13 , the sucking force produced by the suckers 13 increases whenever the wearer causes the feet to step on the shoes S when walking. Further, in the case where the plurality of suckers 13 are provided, there are a plurality of distributed regions where the suckers 13 suck the bottom surface of the heel section S 1 , whereby the heel cover 1 is more unlikely to be detached from the heel section S 1 .
  • the side surface of the fitting section 11 is provided with the suckers 14 , . . . each having an inverted scale of a fish.
  • the configuration described above allows the heel cover 1 to be further unlikely to be detached from the heel section S 1 based on the sucking force and return force produced by the suckers 14 , . . . each having an inverted scale of a fish.
  • the suckers 13 can be arbitrarily placed on the fitting section 11 .
  • the suckers 13 can be placed on the bottom and side surfaces of the fitting section 11 , only on the bottom surface, or only on the side surface.
  • the planar arrangement of the suckers 13 on the bottom and side surfaces may be a zigzag arrangement, a lined-up arrangement, or any other arrangement.
  • the size of the suckers 13 can vary on a location basis.
  • a double-sided tape as the means for joining the fitting section 11 to the heel section S 1 , on the bottom surface of the fitting section 11 .
  • the configuration described above allows the heel cover 1 to be further unlikely to be detached from the heel section S 1 based on the joining force produced by the double-sided tape as the joining means. Further, for example, in a case where the heel section S 1 has irregularities, the fitting section 11 can be bonded to the heel section S 1 with an adhesive.
  • Example 2 will next be described.
  • the same or equal portions in terms of contents as those described in Example 1 have the same reference characters in the description of Example 2.
  • the shoe heel cover 1 according to Example 2 primarily differs from the shoe heel cover 1 according to Example 1 in that three I-letter-shaped arms 15 , . . . , which each have a hook-shaped front end that latches to an edge of the shoe body S 0 that is the edge along which the foot is inserted into the shoe body S 0 , as shown in FIG. 5 , and that the latching force produced by the arms 15 , . . . and acting on the shoe body S 0 causes the heel cover 1 to be further unlikely to be detached from the heel section S 1 .
  • each of the arms 15 . . . is so chamfered as not to hurt the foot of the person who wears the shoe S.
  • the arms 15 may be formed of only an arm that latches to a rear portion of an edge of the shoe body S 0 that is the edge along which the foot is inserted into the shoe body S 0 , or the arms 15 may be formed of arms that latch to inner and outer portions of the edge. That is, the number of arms 15 is not limited to three and may instead be one, two, or even four or more.
  • the arms 15 each do not necessarily have the I-letter shape shown in FIG. 5 and may have any shape.
  • the arms 15 may each have a T-letter shape or a Y-letter shape having a branched front end or may each be formed of arms intersecting each other in an X-letter shape.

  • the latching section 12 in Example 1 can, of course, further be provided in addition to the arms 15 .

  • Example 3 will next be described.
  • the same or equal portions in terms of contents as those described in Examples 1 and 2 have the same reference characters in the description of Example 3.
  • the shoe heel cover 1 according to Example 3 primarily differs from the shoe heel cover 1 according to Example 1 in that the heel cover 1 extends to a toe section of the shoe S, and that a toe cover 16 is provided at the front end of the heel cover 1 to also prevent wear of the tow section as shown in FIG. 6 .
  • the bottom surface of the toe cover 16 can be thicker than the other extending section of the heel cover 1 in consideration of wear.
  • the configuration described above can prevent wear of an outsole section of the toe section of the shoe S. Further, latching the heel cover 1 to the shoe S in such a way that the toe cover 16 covers the toe allows an increase in the strength at which the heel cover 1 is attached to the shoe S, whereby the entire heel cover 1 is unlikely to be detached from the shoe S.

  • the heel cover 1 according to the present example is configured to cover not only the heel section S 1 of the shoe S but the portion from a foot arch section to a toe section so that heel cover 1 covers the entire sole (outsole section) of the shoe S.
  • the heel cover 1 according to the present example includes the overhanging section 17 , which is curved inward at the upper end of the L-letter-shaped latching section 12 and protrudes in the form of eaves, as shown in the cross-sectional view of FIG. 8 .
  • the front end of the overhanging section 17 preferably extends inward beyond an imaginary position of the upper section of the shoe S in the state in which the heel cover 1 is not fitted to the shoe S, so that the overhanging section 17 is so deformed as to come into intimate contact with the upper section with no gap therebetween in the state in which the heel cover 1 is fitted to the shoe S.
  • the configuration described above can prevent not only wear of the entire sole of the shoe S but entry of water via the sole of the shoe S to enhance the waterproofness of the shoe S. Further, since the overhanging section 17 is provided, the overhanging section 17 is in contact with the upper section and other sections of the shoe S with no gap therebetween, whereby the prevention of entry of water, for example, via the upper section can enhance the waterproofness of the shoe S.

Further, also covering the upper section 18 of the shoe S prevents entry of water via the upper section 18 to further enhance the waterproofness of the shoe S. In addition, since the entire shoe S is fitted into the heel cover 1 , the heel cover 1 is unlikely to be detached, and fixing the heel cover 1 with the belts 19 and the snaps 19 a further causes the heel cover 1 to be unlikely to be detached.

  • the plurality of protruding pieces 51 , . . . disposed as described above allow the heel cover 1 to be used with a variety of heel sections S 1 of the shoe S.
  • the protruding pieces 51 are each drawn as a right-angled triangle, but not necessarily, and may have any shape.
  • the protruding pieces 51 may each have a semi-circular shape, as shown, for example, in FIG. 13( b ) .
  • the side surface section 32 on the side close to the front of the fitting section 11 is preferably provided with a plurality of cutouts 52 as the positioning means, as shown in FIG. 13( c ) .
  • the cutouts 52 do not need to pass through the sidewall in the upward/downward direction, and it is also preferable to provide only a heightwise portion of the sidewall with the cutouts 52 , as shown in FIG. 13( d ) .
  • the side surface section has an elliptical shape in the plan views has been described with reference to FIG. 13( a ) , but not necessarily. It is also preferable that the side surface section is formed in a “semi-cylindrical shape with no corners” or a “semi-cylindrical shape with rounded corners (or “quadrangular shape with rounded corners”),” as shown in the lower portion of FIG. 14 . Forming the side surface section in a “semi-cylindrical shape with no corners” allows the heel cover 1 to be fitted in an arbitrary position relative to the heel section S 1 .
  • the front edge (upper edge in FIG. 14 ) and the side edges (right and left edges in FIG. 14 ) of the “semi-cylindrical shape with no corners” may or may not each have a straight portion and can each be formed in an arcuate shape with no straight portion.
  • a “(typical) semi-cylindrical shape (with corners)” possibly causes the corners of the semi-cylindrical shape to protrude if the size of the heel section S 1 differs from the size of the heel cover 1 , as shown in the upper and middle portions of FIG. 14 .
  • the heel cover 1 is narrow in the lateral direction and long in the longitudinal direction as compared with the heel section S 1 , the right and left portions of the front edge protrude in the form of ears, as shown in the upper portion of FIG. 14 .
  • the heel cover 1 in a case where the heel cover 1 is wide in the lateral direction and short in the longitudinal direction as compared with the heel section 51 , the front portions of the side edges protrude rightward and leftward in the form of ears, as shown in the middle portion of FIG. 14 .
  • the heel cover 1 does not conform to the heel section S 1 , and the heel cover 1 possibly comes off the heel section S 1 because the inside air leaks out through the ear-shaped gaps or water enters the heel cover 1 .
  • the protruding ear-shaped portions are likely to latch to an external structure, so that the safety of the wearer who is walking could be compromised, and the heel cover 1 is more likely to come off the heel section S 1 .
  • the heel cover 1 according to the present embodiment which has corners rounded in advance, can prevent the corners from protruding.
  • Example 7 will next be described with reference to FIGS. 16 to 18 .
  • the same or equal portions in terms of contents as those described in Examples 1 to 6 have the same reference characters in the description of Example 7.
  • the shoe heel cover 1 according to Example 7 is characterized in that an outsole section 60 , which forms the outer surface of the bottom surface section 31 , includes a bellows 62 , as shown in FIG. 16 . That is, the outsole section 60 includes a patterned section 61 , which serves as cleats, such as those in related art, and the bellows 62 , which causes the entire bottom surface section 31 to extend in the in-plane direction of the bottom surface section 31 .
  • the bellows 62 has a bellows-shaped (accordion-shaped, zigzag) cross section formed of a plurality of protrusions and recesses along the direction from the center of the bottom surface section 31 toward the outer circumference thereof, as shown in the cross-sectional view of FIG. 20 .
  • the heel cover 1 including the bellows 62 when it is entirely made of a flexible (elastic) material, can extend or contract in the in-plane direction of the bottom surface section 31 from the center toward the outer circumference thereof.
  • the bellows 62 preferably has a shape in the plan view similar to the shape in the plan view (shape of outer circumferential portion) of the bottom surface section 31 , as shown in FIG. 16 .
  • the bellows 62 is preferably formed also in a quadrangular shape with rounded corners in the vicinity of the outer edge of the bottom surface section 31 .
  • the shape of the bellows 62 may not be similar to the outer shape of the bottom surface section 31 , as will be described later.
  • a variety of variations of the shape of the bellows 62 and the number thereof are conceivable, as will be described below.
  • a first bellows 62 and a second bellows 62 a form double bellows 62 and 62 a, as shown in a variation shown in FIG. 17 .
  • the outsole section 60 of the heel cover 1 is preferably formed of the outer first bellows 62 and the inner second bellows 62 a.
  • a patterned section 61 is formed between the first bellows 62 and the second bellows 62 a.
  • only the inner (second) bellows ( 62 a ) may be provided, and the outer (first) bellows ( 62 ) may not be provided.
  • the configuration described above is advantageous in that the bellows ( 62 a ) can be placed in a position excluding the vicinity of the outer circumference of the outsole section 60 , which is likely to wear.
  • roughly cross-shaped bellows 62 b and 62 c can also be formed, as in a variation shown in FIG. 18 .
  • the outsole section 60 of the heel cover 1 is preferably formed of the vertical bellows 62 b, which ensures expansion in the horizontal direction, the horizontal bellows 62 c, which ensures expansion in the vertical direction, and the patterned section 61 , which is divided into four.
  • the combination of bellows similar to each other ( 62 , 62 a ) and cross-shaped bellows ( 62 b, 62 c ) is also conceivable.
  • the outsole section 60 of the bottom surface section 31 of the fitting section 11 of the heel cover 1 includes the bellows 62 , which has a shape roughly similar to the shape of the bottom surface section 31 in the plan view so that the bottom surface section 31 readily extends and contracts in the in-plane direction thereof.
  • the heel cover 1 is therefore likely to extend in the in-plane direction of the bottom surface section 31 , whereby the heel cover 1 is likely to conform to the heel section S 1 of the shoe S.
  • the double bellows 62 and 62 a can also be placed.
  • the double bellows 62 and 62 a allow the heel cover 1 to further readily extend and contract, whereby the heel cover 1 is more likely to conform to the heel section S 1 of the shoe S.
  • the outsole section 60 of the bottom surface section 31 of the fitting section 11 preferably includes the roughly cross-shaped bellows 62 b and 62 c so that the bottom surface section 31 readily extends and contracts in the in-plane direction thereof.
  • the heel cover 1 is therefore likely to extend in the in-plane direction of the bottom surface section 31 , whereby the heel cover 1 is likely to conform to the heel section S 1 of the shoe S.
  • heel cover 1 is used as part of a shoe S used by men, but not necessarily, and can, or course, be used as part of a shoe used by women.
  • the heel cover 1 can be used as part of child shoes, boots, and other shoes. Further, the heel cover 1 can be used as part of boots used by men and women.
  • Example 1 has been described with reference to the case where the heel cover 1 fitted to the heel section S 1 includes the L-letter-shaped latching section 12 , but not necessarily, and may include an I-letter-shaped cross section having no latching section.
  • Example 4 has been described with reference to the case where the heel cover 1 has the L-letter-shaped cross section with the latching section 12 provided along the entire circumference thereof, but not necessarily, and may have having an I-letter-shaped cross section having no latching section provided along the entire circumference thereof.
  • the combination of an L-letter-shaped cross section and an I-letter-shaped cross section can be used along the entire circumference of the heel cover 1 , for example, the front side has an L-letter-shaped cross section, and the rear side has an I-letter-shaped cross section.
  • Example 6 has been described with reference to the case where the side surface section is provided with the air grooves 41 , but not necessarily, and the side surface section may be provided with no air groove 41 .
  • the vacuum state can be maintained in two stages. That is, the plurality of suckers 13 , . . . can maintain the vacuum state in a redundant manner, and the side surface section that surrounds the entire bottom surface section can achieve a vacuum state all over the entire bottom surface section. Further, frictional force produced between the inner surface of the side surface section and the outer surface of the heel section S 1 also causes the heel cover 1 to be unlikely to be detached.
  • the heel cover 1 preferably further includes an adjustment member 70 .
  • the adjustment member 70 is made of the same material as that of the fitting section 11 and is so formed as to have a thin semi-cylindrical cross section with one side surface formed of a flat surface and the other side surface formed of a cylindrical surface.
  • the adjustment member 70 is preferably roughly flush with the heel section S 1 in the height direction.
  • the shape and size of the adjustment member 70 are not limited to those described above and can be another shape and size.
  • the adjustment member 70 is bonded to the heel cover (main body) 1 , for example, with an adhesive. Further, instead of providing the adjustment member 70 as a separate member, it is also preferable to provide an adjustment member 71 (dashed line in FIG. 19 ) integrally molded with the heel cover 1 in advance.
