TECHNICAL FIELDThis invention relates to wheeled shoe accessories and to shoes for use with such accessories.
BACKGROUNDThere have been several proposals over the last century, and earlier, for walking shoes that can be readily converted to function temporarily as roller skates. A principal advantage to such shoes is the enhanced flexibility in transportation modes that they afford. Most are familiar with the rigid skate frames from several years ago that strapped to the underside of practically any normal walking shoe to permit the wearer to roll upon four wheels arranged two forward, two rear, in a forward or normal walking direction as in a standard roller skate. There is at least one walking shoe on the market that contains wheels that can be retracted into the sole of the shoe for walking, and then extended for rolling. Of course, such shoes require soles with thicknesses sufficient to fully contain such rollers when retracted, but have the advantage of not requiring their rolling parts to be carried separately while walking.
In a rolling mode with these and standard roller skates, the wearer generally is able to propel himself along with alternating forward thrusts with each foot, in a motion similar to ice skating. The direction of travel is generally determined by the fore-aft or toe-heel axis of the foot. In-line skates have their wheels aligned along the fore-aft center line of the shoe, and can provide some directional control by tilting the skate to change the camber of the wheels. Some in-line skates have been employed for sliding down railings in a direction perpendicular to the fore-aft shoe centerline, either by sliding down the railing with the railing positioned between a middle pair of rollers, or on skid plates between the wheels.
There is another shoe that has a removable roller mounted in a cavity the heel of the sole. For walking, the roller can be completely removed from its cavity. In a rolling mode, the wearer can, with practice and balance, roll in a forward direction upon the cylindrical roller with ankle locked and shin flexed. To obtain forward momentum, the wearer is instructed to run on the forward portions of the soles, and then lean back to engage only the heel rollers of both shoes with the ground for sustained rolling in the fore-aft direction as determined by the roller geometry and orientation.
Skateboarding is yet another mode of transportation and sport popular with young people. Skateboards are generally characterized as boards supported by forward and rear “trucks,” each having a pair of wheels mounted upon a tiltable axle. While rolling forward on the board, side-to-side weight fluctuations tilt the board and cause a shift in the rolling direction of the wheels to provide controllable steering of the board. The rolling direction is thus determined by the orientation of the wheel axles, although the normal rolling direction is along a major fore-aft axis of the board. It is common for the skateboarder to place her feet at an angle with respect to the major board axis, with one foot behind the other, similar to the stance of a surfer on a surfboard.
SUMMARYAccording to one aspect of the invention, a wheeled shoe accessory includes a rigid board having upper and lower surfaces and defining a longitudinal axis configured to be oriented along a rolling direction of the wheeled shoe accessory, the upper surface of the board having a length along the longitudinal axis sufficient to span a width of a piece of footwear placed sideways across the board, with the board supporting an arch region of the piece of footwear. In some embodiments, the board is sized to fit entirely under the piece of footwear. Preferably, the board is of a length, measured along the longitudinal axis, of between about 8 and 14 inches, and is of a width, perpendicular to its longitudinal axis, of between about 2½ and 4 inches.
At least one axle assembly is secured to the lower surface of the board. The axle assembly includes an axle and at least one roller rotatably mounted on the axle for rolling in the rolling direction. Preferably, the axle assembly includes a compliant mount resiliently deformable and secured to the lower surface of the board, the compliant mount defining a canted kingpin axis. The axle is secured to the compliant mount and rotatable about the canted kingpin axis for inducing yaw with respect to the rolling direction. In some configurations, the wheeled shoe accessory includes first and second axle assemblies with their compliant mounts secured to the lower surface of the board such that their canted kingpin axes are in opposing directions to one another.
The wheeled shoe accessory also has at least one releasable fastener configured to secure the board to an underside of the piece of footwear to retain the wheeled shoe accessory to the piece of footwear during use. In some embodiments, the releasable fastener is a projection extending upwardly from the upper surface of the board and configured to be received by a receptacle defined by a sole of the piece of footwear. In one example, the projection is of a shape selected to prevent rotation of the board about an axis normal to the board with the projection received in the piece of footwear. Preferably, the projection is elongated with its length extending along the longitudinal axis of the board. In a presently preferred embodiment, the releasable fastener is a substantially rectangular mounting boss having a height of about ¾ inch, a length of about 1⅛ inch, and a width of about ¾ inch. Preferably, the releasable fastener is configured to permit the piece of footwear to be selectively positionable on the board in either of two positions, each with the piece of footwear angled with respect to the rolling direction. For example, the releasable fastener may be securable to the board in either of at least two angular orientations. In one example, the releasable fastener defines a center axis and opposing undercuts on either side of the center axis for receiving an attachment mechanism embedded in an underside of the piece of footwear. Preferably, the undercuts defined by the releasable fastener are of an elongated shape spanning the width of the releasable fastener and have a height of about ⅛ inch and a depth of about 3/16 inch.
In some embodiments, the wheeled shoe accessory also includes an orientation plate secured to the upper surface of the board and configured to receive the releasable fastener. The orientation plate defines a protrusion along its upper surface to align the received releasable fastener in a particular orientation with respect to the board's longitudinal axis.
In another aspect, an article of footwear includes a sole, an upper portion joined to the sole, and an attachment mechanism embedded in the sole for securing a wheeled shoe accessory to the sole. The attachment mechanism includes a body defining an elongated receptacle and a longitudinal axis, the receptacle defining a center axis and configured to receive a mounting boss of a wheeled shoe accessory. In some embodiments, the receptacle defines a substantially rectangular opening. The attachment mechanism also includes at least one manually operable lock control device configured to engage and retain the received mounting boss within the receptacle. For example, in some embodiments, the lock control device includes a button actuator disposed in the body along the longitudinal axis of the body and accessible from the side of the sole. A retainer arm is disposed in the body and joined to the button actuator, the retainer arm configured to engage and retain the received mounting boss in the receptacle with the retainer am in an engagement position. A spring is disposed in the body and biases the retainer arm toward its engagement position. Preferably, the lock control device includes two oppositely directed buttons joined to respective retainer arms configured to engage the mounting boss from opposite directions.
Some other aspects of the invention feature a rigid board for a wheeled shoe accessory, the board having upper and lower surfaces and defines a longitudinal axis configured to extend along a rolling direction of the wheeled shoe accessory. The upper surface of the board has a length along the longitudinal axis sufficient to span a width of a piece of footwear placed sideways across the board, with the board supporting an arch region of the piece of footwear.
According to one such aspect, the board defines mounting holes arranged to mount at least one axle assembly on the lower surface of the board, and includes a projection extending from its upper surface and configured to selectively secure a releasable fastener in either of two selectable orientations with respect to the longitudinal axis of the board. In some embodiments, the projection his two elongated ribs oriented at different angles with respect to the longitudinal axis of the board, and a central post defining a threaded hole therein for receiving a threaded fastener to secure the releasable fastener to the board. According to another such aspect, the board defines a generally square recess in the upper surface along the longitudinal axis for receiving an orientation plate for selectively positioning a releasable fastener secured to the upper surface of the board in a particular orientation with respect to the board's longitudinal axis. Preferably, the recess has a side length of about 1¼ inches and a depth of about 0.2 inch. In some embodiments, the board further defines a hole therethrough at a center of the recess of about ¼ inch in diameter.
Various implementations of the concepts disclosed herein enable an enhanced user experience resulting from rolling in a direction other than a walking direction, while allowing individual foot maneuverability. Unlike skateboarding and surfing, the user's feet are decoupled to permit individual foot angulations and travel paths, while allowing the user to face at an angle to the general direction of motion. As a result, wheeled shoe accessory users can perform complex foot movements while rolling sideways. In addition, the disclosed wheeled show accessories can be employed for other purposes when not secured to footwear, such as by serving as hand-held toys for play. For example, decorative covers may be placed over the releasable fasteners, such as to simulate miniature characters “riding” the boards. Alternatively, the releasable fastener may be replaced with a flat plate that enables the board to be ridden by smaller children, or by larger children on only one foot in standard footwear. Hand grips may also be releasably secured to the fasteners, enabling a user to roll on either one or two pairs of such wheeled shoe accessories, at least partially supported on his or her arm or arms.
The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.
