Description
- The invention relates to foldable footwear, soles for foldable footwear and particularly, but not exclusively, to footwear that can be folded for packaging in a format suitable for sale from vending machines.
- The invention provides a sole for foldable footwear, said sole having a plurality of defined fold lines arranged such that the sole can be folded so as to have a folded length that is less than its unfolded length.
- The invention also includes a foldable shoe comprising a sole and an upper connected with the sole, the sole having a plurality of defined fold lines arranged such that the shoe can be folded so as to have a folded length that is less than its unfolded length.
- The invention also includes a method of folding a foldable shoe, the foldable shoe having a plurality of defined fold lines and the method comprising folding the shoe along the fold lines such that the shoe has a folded length that is less than an unfolded length.
- The invention also includes a package for a pair of foldable shoes, the package comprising a first receptacle for a foldable shoe, a second receptacle for a foldable shoe and a hinge connecting said receptacles.
- In order that the invention may be well understood, some embodiments thereof, which are given by way of example only, will now be described with reference to the drawings in which:
-
FIG. 1 is a plan view of the underside of a sole for foldable footwear; -
FIG. 2 is a side elevation of the sole ofFIG. 1 ; -
FIG. 3 is an exploded perspective view of a foldable shoe comprising the sole ofFIG. 1 ; -
FIG. 4 is a perspective view showing the foldable shoe ofFIG. 3 in a folded condition; -
FIG. 5 is a perspective view showing another foldable shoe; and -
FIG. 6 is a schematic perspective view of a package for the foldable shoes ofFIGS. 3 and 5 , with the package shown in an open condition. - Referring to
FIGS. 1 and 2 , a sole 10 for foldable footwear comprises a generally planar moulding having atoe end 12, aheel end 14, aninstep side 16 and anouter side 18 that is opposite the instep side. The sole 10 has anupper surface 20 and anunderside 22 that in use faces the ground. Theunderside 22 is provided with a plurality of ground engaging projections in the form of respective sets of ribs 24-32. The sets of ribs 24-32 are separated by spaces that define respective fold lines 34-40 along which the sole 10 can be folded. - As can be seen in
FIG. 1 , the fold lines 34-40 extend in a widthways direction of the sole 10 and are inclined with respect to a notionallengthways extending line 42 that bisects the sole in the lengthways direction. Thefold lines instep side 16 of the sole towards thetoe end 12 and thefold lines heel end 14. It will be noted that the direction of inclination of the fold lines 34-40 alternates. - The first two sets of
ribs toe end 12 and the set ofribs 32 at theheel end 14 extend in the lengthways direction of the sole generally parallel to theline 42. The two sets ofribs line 42 from theinstep side 16 towards thetoe end 12. The arrangement of the sets of ribs 24-32 and fold lines 34-40 is such that when the sole 10 is folded, the sets of ribs on portions of the sole that face one another can mesh (ie the ribs on one of two facing portions enter the spaces between the ribs on the other of the two facing portions). This meshing arrangement minimises the thickness of the folded sole. - Referring to
FIG. 3 , afoldable shoe 50 comprises thefoldable sole 10, a set of stiffening members in the form of shims 52-60 that lie on theupper surface 22 of the sole and a cushion (or insole) 62, which lies on top of the shims to complete the foot supporting portion of the shoe. The shims 52-60 are shaped to fit over the ribbed areas of the sole 10 and leave gaps between corresponding to the fold lines 34-40. Thus the configuration of the shims 52-60 is such as to maintain the foldababilty of theshoe 50. The sole 10, shims 52-60 and insole 62 are attached by any suitable means such as by the use of adhesives. - The
foldable shoe 50 further comprises a two-part upper made up of a front upper 64 and a rear upper 66. A hook 68 is provided in the rear upper 66. The front andrear uppers rear uppers shoe 50 is intended for indoor use, for example as a slipper, and particularly where it is intended for one-off use, the upper may simply be a lightweight fabric. Where theshoe 50 is intended for outdoor use, the material used may be a waterproof, or waterproofed, material intended to make the shoe at least capable of withstanding light rainfall or exposure to similar levels of moisture. - The hook 68 comprises a length of suitable cord that runs within seams (not shown) that run along the inside of the upper edge 72 of the rear upper 66 and has respective ends that are trapped between the sole 10 and insole 62.
- In order to fold the
shoe 50 to achieve the folded condition shown inFIG. 4 , the user first folds the shoe along thefold line 36 in the direction of theheel end 14 to bring the rib set 26 into meshing contact with therib set 28. The shoe is then folded along thefold line 40 to bring the rib set 32 into mesh with the rib set 30. The shoe is then folded along thefold line 38 to move the rear upper 66 into engagement with the rearward end of the front upper 64. The folding process is completed by folding the shoe along thefold line 34 such as to fold the toe end of the front upper back towards the rearward end of the front upper. Once the folding process is complete, theshoe 50 has a generally triangular configuration as shown inFIG. 4 . The folded length of theshoe 50 is approximately 40% of its unfolded length. - It should be noted that the order of folding described above does not represent the only way in which the
foldable shoe 50 can be folded to achieve the folded shape shown inFIG. 4 . For example, thefoldable shoe 50 could be folded first alongfold line 40, followed by folding along thefold line 36. Regardless of whether the first fold is made alongfold line 36 orfold line 40 first, the second fold could be alongfold line 38. The particular order of folding is less important that the folds are made in the correct direction. In the illustrated arrangement, theshoe 50 is alternately folded in opposite directions at successive fold lines 34-40. - Referring to
FIG. 5 , anotherfoldable shoe 100 has a foldable sole 110 that has atoe end 112,heel end 114, instepside 116 and anouter side 118 opposite the instep side. In the same way as the foldable sole 10, the foldable sole 110 has five sets of ground engaging ribs 124-132, which are spaced to define four fold lines 134-140. The fold lines 134-140 extend in the widthways direction of theshoe 100 and are inclined in the same way as the fold lines 34-40 of theshoe 10. In the same way as theshoe 50, theshoe 100 has shims and an insole (not show) and a front upper 164 and a rear upper 166. - The difference between the
shoe 100 and theshoe 10 is that the foldable sole 110 is moulded in a contoured mould so that it has a normally non-planar partially folded shape as shown inFIG. 5 . Theshoe 100 and, in particular the foldable sole 110, can be moved to a use position in which it has no substantially no folds. This is most readily achieved by the user inserting his/her feet into the shoe. Theshoe 100 and sole 110 can also be folded into the triangular shape shown inFIG. 4 . Essentially, the same folds are made as previously described for the sole 10. However, because the sole 110 is made such that once removed from a wearer's foot it relaxes to a partially folded condition, the user does not have to remember the folding sequence. Instead, he/she simply completes the folding process by twisting theshoe 100 as indicated by the arrows inFIG. 5 . It is not necessary to make the folds one after the other. The user simply grips the shoe in the region of thetoe end 112 and twists clockwise (as viewed in the drawing) while simultaneously. It will be noted that as with the sole 10, the sole 110 is alternately folded in opposite directions at successive folds 134-140. - When the
soles FIG. 6 , atriangular package 150 for a pair of theshoes 50 orshoes 100 comprises two triangular receptacles in the form ofpockets hinge 156, which is optionally made of an elastomer. Thepackage 150 is shown in an open condition in which therespective entrances 158 to thepockets 152, 154 (only one of which is visible in the drawing) can be accessed to allow the shoes to be inserted in or removed from the pockets. - The
package 150 is closed by bringing the twopockets notional axis 160 that runs generally parallel to the base sides of thepockets entrances 158 are defined. The direction of folding is indicated by thearrows 162. The twopockets pockets package 150 is closed. A suitable location for such pads is shown by dashedlines 164. - The
package 150 may be made of any suitable packaging material and could, for example, be made of cardboard printed with information relating to the shoe size and/or folding instructions. - The relatively small size of the packaged
shoes - The foldable sole is typically a one-piece moulding and can be made of any suitable natural or synthetic polymer.
- It will be appreciated that it is not essential to have four fold lines as in the embodiments. A smaller number may be provided. This would reduce the extent to which the length of the sole could be reduced by folding, but should result in a thinner folded shoe. Alternatively, a greater number of folds could be provided. This allows the possibility of an increase in the extent to which the length of the sole is reduced by folding, but with an increased complexity in the folding arrangement and a potentially thicker folded shoe.
- It will be appreciated that the fold lines do not have to be in the form of spaces separating sets of ribs as in the embodiments. A foldable sole could instead comprise a generally smooth or dimpled ground engaging surface with fold lines defined as grooves in the ground engaging surface.
- It will be understood that while it is preferable that the foldable sole has a substantially constant thickness throughout its length, the portion between the heel end and the fold line closest to the heel end could be of increased thickness to define a raised heel.
- It will be appreciated that the sole of the foldable shoe does not have to be a one-piece moulding as illustrated in the drawings. Instead, a series of pads corresponding, for example, in shape to the shims could be secured to the underside of a relatively soft material with spaces provided to define fold lines corresponding to the illustrated fold lines or any other suitable arrangement.
- It will be understood that while the upper of the foldable shoes conveniently comprises two parts as illustrated in the drawings, that is not essential. The upper could be a one-piece construction with, for example, an overall shape similar to that of the illustrated two-part upper. Alternatively, the shoe may have an upper just at the toe end, in which case, the upper may have a shape similar to the illustrated front upper 66. Yet another alternative would be to have a system of strapping providing a sandal type structure. Such strapping might take the form of an elasticated band at the toe end of the shoe or one, or more, releasable straps that are securable, for example, by a hook and eye type fastener such as Velcro®.
- It will be appreciated that while the foldable shoe is particularly suitable for packaging and sale in a folded condition, this is not essential. It could be sold unfolded. This would still give the purchaser the benefit of a shoe that could be conveniently folded when required.
