Benefits of technology

The invention is a kicking shoe attachment for a kick scooter that improves power and efficiency by extending the length of the kicking leg and shifting the rider's center of gravity towards the kicking foot. The attachment is made from a lightweight sturdy material and includes a resilient structure to reduce shock to the kicking leg. The main body of the attachment has a flat upper surface and a curved lower surface to provide good contact with the ground and traction during the kicking or propelling stroke. The height of the upper and lower soles is ideally equal to the height of the scooter's platform above the ground for casual riding, while for a sporting style, the kicking shoe attachment may be made lower than the platform to shift the rider's center of gravity towards the kicking foot.

Problems solved by technology

The constant flexing of the stationary leg may be very tiring.
However, for a “sporting” style of riding, such an approximately 1:1 ratio of heights may not provide desirable power from the kicking strokes.

first embodiment

[0042]Referring now also to FIG. 2, there is shown a side elevational, schematic view of first embodiment of a kicking shoe attachment in accordance with the invention, generally at reference number 100.

[0043]A solid main body core 102 has a substantially flat upper surface 104, and a convex lower surface 106. In this embodiment, main body core 102 is formed from a solid piece of sturdy, lightweight material. Such lightweight, sturdy materials include lightweight metals such as aluminum and polymers such as ABS. It will be recognized that numerous other lightweight, sturdy materials may be known to those of skill in the art and, consequently, the invention is not limited by the material examples chosen for purposes of disclosure. Rather, the invention is intended to include any suitable main body core 102 material.

[0044]An upper sole 108 is fastened to the upper surface 104 of main body core 102. Upper sole 108 is typically formed from rubber, either natural or artificial, or from a...

second embodiment

[0056]Referring now also toFIG. 5, there is shown a side elevational, schematic view of the kicking shoe attachment with springs within the elongated main body, generally at reference number 150.

[0057]In the kicking shoe attachment 150 elongated main body core 102 of kicking shoe attachment 100 is split into two portions; and upper body portion 152 and a lower body portion 154. Each of upper body portion 152 and lower body portion 154 is thinner than solid main body core 102.

[0058]Coil springs 156 are interposed between a lower surface of upper body portion 152 and an upper surface of lower body portion 154. Springs 156 are typically coil springs having sufficient stiffness to maintain connective integrity between upper body portion 152 and lower body portion 154 while providing a kicking assist to the rider of a kick scooter.

[0059]While coil springs 156 are shown for purposes of disclosure, it will be recognized by those of skill in the art that springs of other types, for example,...

third embodiment

[0060]Referring now also to FIG. 6, there is shown a side elevational, schematic view of the kicking shoe attachment with resilient material within the body generally at reference number 200.

[0061]In kicking shoe attachment 200, springs 156 (FIG. 5) are replaced by a block of a resilient material 202. Materials such as polyurethanes, latex, or polyether urethanes (EU) elastomeric foam have been found suitable for the application. It will be recognized by those of skill in that art that suitable other material may be available. Consequently, the invention is not considered limited to the materials chosen for purposes of disclosure. It is anticipated that kicking shoe attachment 200 is less expensive to manufacture while still providing the kicking assist benefits of kicking shoe attachment 150. Resilient material 202 may readily be adhesively attached to a lower surface of upper body portion 152 and an upper surface of lower body portion 154.

Abstract

A kicking shoe attachment for use by the rider of a kick scooter or the like having an elongated core with a flat upper surface with a skid resistant upper sole thereupon, and an opposing curvilinear lower surface with a wear resistant lower sole disposed thereupon. The elongated core may be split apart horizontally and two or more springs, a block of a resilient material, or a scissor jack mechanism may be placed between the upper and lower body portions. An opening may be placed in the upper surface of the elongated body to receive the protruding heel of typically a woman's heeled shoe or boot. A harness or quick-release safety binding is provided to retain a rider's foot to the kicking shoe attachment.A tether may be provided for securing the kicking shoe attachment to an environmental object when not in use or to the kick scooter when the kick scooter is being ridden.

Description

RELATED APPLICATIONS[0001]This is a Continuation-in-Part Application of U.S. application Ser. No. 14 / 578,631 filed Dec. 22, 2014 for Kicking Shoe Attachment for Propelling Kick Scooters and the Like that is included hereon in its entirety by reference.FIELD OF THE INVENTION[0002]The invention pertains to footwear attachments and, more particularly, to devices attachable to the sole of a shoe or boot that has a height (i.e., thickness) to allow the “kicking” foot equipped with the device to touch the pavement while requiring little or no bending of the a rider's non-kicking leg standing on the kick scooter.BACKGROUND OF THE INVENTION[0003]Kick scooters are well known and widely used. In addition, so-called skate boards have become widely used in recent years. A rider, particularly of a kick scooter places one of his or her feet on the horizontal wheeled platform of the kick scooter and uses his or her other foot to exert pressure against the ground. In accordance with Newton's Third ...
