Abstract
A footwear outer sole comprising a body having an end and a bottom surface, and a revolver provided at the end of the sole body and protruding slightly from its bottom surface. The revolver comprises a lower member supported for rotation relative to the sole body about a substantially vertical axis.
Description
- The present invention relates to an outer sole for a footwear item, such as a shoe or boot.
- Shoes or boots can have wheels, i.e. roller skates, for roller-skating as a sport activity or a game for fun. The wheels are invariably arranged either at the four corners or centrally in-line.
- The subject invention seeks to provide an outer sole for a footwear item that can perform a different action.
- According to the invention, there is provided a footwear outer sole comprising a body having an end and a bottom surface, and a revolver provided at the end of the sole body and protruding slightly from its bottom surface. The revolver comprises a lower member supported for rotation relative to the sole body about a substantially vertical axis.
- Preferably, the end of the sole body includes a recess which opens downwards and in which the revolver is partially located.
- It is preferred that the lower member comprises a substantially horizontal disc.
- In a preferred embodiment, the revolver includes an upper member supporting the lower member for rotation, the upper member being fixed to the sole body.
- More preferably, the upper member comprises a substantially horizontal disc.
- Further more preferably, the lower member comprises a substantially horizontal disc.
- In the preferred embodiment, the two members specifically are connected together by a substantially vertical shaft, the shaft having an upper end secured to the bottom wall of the sole body.
- More preferably, the shaft comprises a bolt and nut.
- It is preferred that the two discs have opposing peripheries overlapping with each other to enclose the interior between the two discs.
- In the preferred embodiment, the revolver advantageously includes a low friction bearing provided between the two members to permit free rotation of the lower member relative to the upper member.
- More preferably, the low friction bearing comprises an annular ball race.
- Further more preferably, the ball race comprises a plurality of spheres and an annular spacer positioning the spheres, and at least one of the two members includes a recessed annular track for the spheres.
- As one example, the revolver is provided at a front end of the sole body.
- As another example, the revolver is provided at a rear end of the sole body.
- The invention also provides a footwear item that incorporates the aforesaid footwear outer sole.
- The invention will now be more particularly described, by way of example only, with reference to the accompanying drawings, in which:
- FIG. 1 is a bottom plan view of an embodiment of a footwear outer sole in accordance with the invention, the sole including a revolver;
- FIG. 2 is a side elevational view of the sole and revolver of FIG. 1;
- FIG. 3 is a cross-sectional side view of the revolver of FIG. 1;
- FIG. 4 is a top plan view of a lower member of the revolver of FIG. 3; and
- FIG. 5 is a bottom plan view of the revolver member of FIG. 4.
- Referring to the drawings, there is shown a rubber
outer sole 100 of a footwear item, such as a shoe, embodying the invention, which sole 100 comprises a flatelongate body 110 and arevolver 200 provided at afront end 112 of thesole body 110. Thesole body 110 has a relativelythick bottom wall 114 formed, at thefront end 112, with acircular recess 116 which opens downwards and in which therevolver 200 is partially located. - The
revolver 200 has a slightly smaller diameter than therecess 116, but a slightly larger thickness such that its bottom surface protrudes slightly beyond that of thesole body 110 for engaging the ground when the sole 100 is in use. Therevolver 200 comprises a horizontal plasticupper disc 210, a horizontal plasticlower disc 220 of the same diameter, and avertical metal bolt 230 connecting thelower disc 220 co-axially to theupper disc 210 through their centers, acting as a shaft. - The
upper disc 210 is generally flat and includes a short dependingperipheral wall 212, whereas thelower disc 220 is considerably thicker and includes an upstandingperipheral wall 222 and an upstanding hollowcentral boss 224. The upperperipheral wall 212 has an annularouter step 213 that mates with a complementary annularinner step 223 of the lowerperipheral wall 222. The twoperipheral walls steps discs discs peripheral walls central boss 240, is annular and flat. - The
revolver 200 includes a low friction bearing in the form of anannular ball race 240 provided co-axially in the interior between the twodiscs ball race 240 is formed by sixmetal spheres 242 and a plasticannular spacer 244 that locates thespheres 242 equi-annularly byrespective holes 246. Thespheres 242 run between and against the confronting inner surfaces of the twodiscs lower disc 220 includes co-axially a raisedcircular track 226 for thespheres 242, which has a recessed cross-section locating thespheres 242 and hence theoverall ball race 240. In addition, the inner surface of theupper disc 210 may include co-axially a circulargrooved track 216 likewise for thespheres 242. - The
bolt 230 extends upwardly through thelower disc 220 and then theupper disc 210, with itsbolt head 232 retained and accommodated within the hollow of thecentral boss 224.Free end 234 of thebolt 230 projects out of theupper disc 210 and then through thebottom wall 114 of thesole body 110 centrally at the base of therecess 116. Anut 236 fastens thebolt end 234 tight, thereby securing therevolver 200 in therecess 116. - More specifically, the
upper disc 210 is fastened tight against thesole bottom wall 114 such that it is fixed against rotation. On the other hand, thelower disc 220 remains freely rotatable by reason of theball race 240 relative to theupper disc 210. - A wearer of the aforesaid shoes may stand on one leg and tiptoe on the associated
revolver 200 to spin or turn about a substantially vertical axis using therevolver 200 for fun or playing or as an exercise to twist the waist in opposite directions. In this regard, thelower disc 220 may have small protrudingknobs 228 over its bottom surface to hence gripping on the ground. Given that thefront end 112 of thesole body 110 normally curves slightly upwards and therevolver 200 is only slightly protruding, the wearer can walk or run with hissoles 100 flat on the ground. - It is envisaged that the
same revolver 200 can of course be provided at the opposite, rear end of thesole body 110, such that the wearer can turn on his/her ankle. As a further variation, the sole 100 may include tworevolvers 200 at its both front and rear ends. - The subject
outer sole 100 may be used on any other types of footwear, such as boots and sneakers. - The invention has been given by way of example only, and various other modifications and/or variations to the described embodiment may be made by persons skilled in the art without departing from the scope of the invention as specified in the accompanying claims.
