Abstract
Footwear comprising a detachable wheel assembly such that a wheel protrudes from a first face of the wheel assembly and is recessed from a second, opposite face of the wheel assembly. An engaging mechanism detachably engages the wheel assembly in a first orientation in which the wheel protrudes from the bottom of the wheel assembly, or in a second position in which the wheel is recessed from bottom of the wheel assembly and thereby from the supporting surface. The footwear may also have a skid pad to enable a user to come to a gradual stop rather than an abrupt stop.
Description
- The present invention relates to footwear. In particular, the invention relates to footwear having at least one wheel for rolling.
- There have been a variety of mechanisms developed to allow a person to roll on footwear, for use by children and adults alike. Some footwear is made specifically for rolling, for example integral roller skates, including “in-line” skates, which are permanently equipped with wheels. While roller skates are particularly adapted for allowing the user to roll or skate, and are thus useful both for sport and as a mode of transport, they are at best awkward to wear indoors and not viable for wear in places where rolling is not permitted or where rolling is not possible (for example on soft grass or coarse gravel).
- Thus, when used as a mode of transport a user must typically carry along normal footwear and switch to the normal footwear where rolling is unsafe or not permitted, such as in many malls or professional offices, or to travel over ground unsuitable for rolling. For convenience, there has been developed wheeled footwear having removable wheels. This is somewhat more practical for use as a mode of transport, as the wheels can simply be removed in places where rolling is not permitted or practical. However removal often requires the use of tools or strenuous effort. Moreover, the wheel assemblies must be carried around by the user when not in use, which is inconvenient.
- U.S. Pat. No. 6,406,038 issued Jun. 18, 2002 to Adams, which is incorporated herein by reference, teaches a heeling apparatus that includes a shoe with a wheel built into the heel that allows one to roll on smooth ground. In such a heeling apparatus the wheel is not able to be easily removed to allow a user to walk normally. Since the installed wheel permanently protrudes below the bottom of the heel, it is not possible for the user to walk normally without removing the wheel.
- Further, a user of such wheeled shoes comes to a stop from rolling by placing the front sole portion of the shoe on the supporting surface. Such an action often leads to abrupt and sudden stops, which can cause a user to tumble over. This may lead to a variety of injuries.

detachable wheel assembly 14 so that the footwear that can be used for either walking normally or for rolling along a surface by raising the forepart of the footwear so that only thewheel 16 contacts a supporting surface. The invention will be described and illustrated in the context of a shoe 10, however it will be appreciated that the principles of the invention can be applied to any type of footwear and the invention is not intended to be limited to any particular type of footwear. - As shown in
FIG. 1 , a shoe 10 has a sole 11 (FIG. 1 shows the shoe upper 10 a schematially.) The sole 11 may be composed of any suitable material, but preferably is comnposed of, or augmented with, a material that will not wear unduly quickly due to scraping encountered during rolling. The sole 11 comprises arecessed portion 12 for receiving awheel assembly 14. In the preferred embodiment therecessed portion 12 is disposed in the heel region of the sole 11, so that the user rolls on the heel of the foot, however it is possible to dispose thewheel assembly 14 in other positions on the sole 11. Further, while therecessed portion 12 is shown in the drawings as completely open, therecessed portion 12 of the sole may optionally have a peripheral wall (not shown) for aesthetic purposes. Therecessed portion 12 of the sole 11 is provided with acavity 13 for purposes explained below. - The
detachable wheel assembly 14 comprises awheel 16 mounted to an axle 17 (shown inFIG. 5 ). Thewheel assembly 14 has acavity 18 within ahousing 20, to which theaxle 17 is mounted, for example embedded in thehousing 20 such that thewheel 16 rotatably protrudes from afirst face 14 a of thewheel assembly 14 and is flush with or preferably slightly recessed from a second, opposite face 14 b of thewheel assembly 14. Thewheel 16 may be made of any suitable material such as, for example, urethane, plastic, polymer, metal, rubber, or a composite material, or the like, as is well known to those skilled in the art. Theaxle 17 may similarly be made of any suitable material, preferably a low friction material such as steel. Thewheel 16 andaxle 17 may be molded into thehousing 20, or thehousing 20 may be formed in two parts and adhered together with thewheel 16 andaxle 17 in position. - In the preferred embodiment the
wheel assembly 14 is engaged to therecessed portion 12 by an engaging mechanism comprising at least one engaging member orclip 22 projecting from the sole 11 in the recessedportion 12. In the preferred embodiment, fourengaging clips 22 project from the sole 11, generally evenly distributed about the periphery of the therecessed portion 12. Theengaging clips 22, preferably formed from a sturdy, rigid or semi-rigid plastic such as nylon, are aligned withcomplementary slots 24 disposed about thehousing 20 of thewheel assembly 14 and comprise snap-fit openings 25 into which thestems 32 ofpins 30, shown inFIGS. 10 and 11 , are locked when thewheel assembly 14 is engaged to the sole 11. Thepins 30 are inserted intoopenings 31 in the sides of the wheel assembly 14 (shown in phantom inFIG. 6 ) so that the pins extend laterally, generally centrally, through therespective slots 24. - To attach the
wheel assembly 14 to the sole 11, theslots 24 are aligned with theengaging clips 22 and the wheel assembly is depressed toward the sole 11. Theslots 24 serves as guides, aliging the snap-fit openings 25 with thestems 32 ofpins 30, and as the wheel assembly gets close to the sole 11 thepins 30 slide into the entrance of the complementary openings 25 as shown inFIG. 7 and finally snap into the engaging position shown inFIG. 8 . Thewheel assembly 14 can be detached by applying force in the opposition direction, to pull thepins 30 out of openings 25 and separate thewheel assembly 14 from the sole 11. - To securely engage the
pins 30 in theopenings 31, thepins 30 may include a stationary washer 34 a and a movable washer 34 b slidably received on thestem 32, with a spring 38 therebetween, as shown inFIGS. 10 and 11 . Thepin 30 can be pushed into opening 31 with theflat end 36 oriented in the direction of a vertical slit inside the opening 31 (not shown) and then rotated 90 degrees to lock thepin 30 in theopening 31 under the pressure of compression spring 38. However, any other suitable method of securing thepins 30 in theopenings 31 is possible, including molding thepins 30 directly into the housing of thewheel assembly 20, and the invention is not intended to be limited thereby. - In use, when the
wheel assembly 14 is in the first orientation in which thewheel 16 protrudes from the bottom of thewheel assembly 14, by raising the forepart portion of the sole 11 the user can roll along the supporting surface, and stop by lowering the forepart portion of the sole 11 so that both the forepart of the sole 11 and thewheel 16 contact the supporting surface. To switch to a walking mode, thewheel assembly 14 is detached by pulling or prying it away from the sole 11, reversing its orientation, and reattaching thewheel assembly 14 to the sole in the second orientation in which thewheel 16 is flush with or recessed from the bottom of thewheel assembly 14, thereby providing a walking surface on the sole 1 1 of the footwear 10. In the second orientation thewheel 16 projects into acavity 13, extending into therecessed portion 12 of the sole 11, as shown in phantom inFIG. 2 . - In the preferred embodiment the forepart region of the sole 11 is augmented by a
skid pad 40, shown inFIG. 4 , that has a lower coefficient of friction than the bottom surface of the sole 11 and thus enables a user to come to a gradual rather than an abrupt stop when the forepart portion of the sole 11 is lowered to the supporting surface. The skidpad 40 can be made from any suitable material that allows for a gradual slowing down of a user and resists wear due to abrasion, for example thermoplastic rubber, thermoplastic polyurethane or polyvinyl chloride. - Various embodiments of the present invention having been thus described in detail by way of example, it will be apparent to those skilled in the art that variations and modifications may be made without departing from the invention. The invention includes all such variations and modifications as fall within the scope of the appended claims.
