Description

BACKGROUND OF THE INVENTION

The invention relates to novelty shoes, especially for children.

Shoes are fashioned to provide comfort and support, as well as to be aesthetically pleasing to the eye. For example, logos, stylized designs and decorative marks are often placed on the outer surfaces of the shoe.

Lights and sound-emitting devices have also been fixedly attached to or molded within a shoe to be sportive or amusing.

It has been known to attach display and other articles to the surface of shoe uppers. For example, Skaja U.S. Pat. No. 4,837,960 shows identification elements attached to a shoe by engagement of a peripheral mounting rib in a corresponding circumferential groove in the identification element. Skaja also mentions attachment of articles by means of VELCRO.RTM. hook-and-loop type fasteners, e.g. as shown in Kellin et al. U.S. Pat. No. 5,136,726. Goria U.S. Pat. No. 4,712,319 describes shoes with detachable visibility aids held in place by spaced mounting appendages grasping the edge of a flange at the rear of the visibility aid. McGowan U.S. Pat. No. 3,114,982 describes an athletic shoe with weights in a removable case attached to the shoe upper with releasable snaps.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a shoe 10 of the invention has a sole 11 and an upper 16, with one or more custom-designed ornamental charms 18 having a primary display surface 25. The charm is removably displayed on the outer surface of the upper, as described below. The shoe upper 16 is preferably canvas or leather, but may be formed of any other suitable material. A female component 12, which provides a base for attachment of the ornamental charms 18, is sewn with a portion extending beneath an outer layer 17 of the upper 16.

Referring now to FIGS. 2-4, female component 12 has a body consisting of a flat circular disk 14 having a predetermined thickness, e.g. 1.50 mm, and formed of a suitable, relatively resilient material, e.g. polyvinyl chloride (PVC) or polypropylene. Extending above an upper surface 21 (FIG. 2) of disk 14 is a secondary display portion display portion 20 having a heart shape exposed within an aperture 19 of complementary shape defined in the outer layer of the shoe upper.

The female component defines a through aperture 22 having a first, upper portion 23 of predetermined diameter, e.g. 2.6 mm, defined by a first encircling edge 27 sized for receiving, in snap-fit engagement, a corresponding member 34 extending from a rear surface 26 of charms 18 (FIGS. 5 and 6). The female component further defines a second, lower portion 28 the aperture, coaxial with upper portion 23, also having a predetermined diameter, e.g. of 6.0 mm, with a depth of about 2.0 mm measured from the bottom surface 30 of the disk. The interface between aperture portions 23 and 28 is defined by a circumferential lip or an encircling second edge 32, with the relatively larger radius of second aperture portion 28 providing flexibility to the lip to allow passage of the extension member 34 upon application of axially applied force (arrow A), while resisting displacement due to transversely applied forces, such as occurs during running and jumping.

Referring to FIGS. 5 and 6, an exemplary one of a variety of charms 18 is shown having a male component 33 in the form of the cantilevered member 34 extending from rear surface 26 of the charm. Cantilevered member 34 is formed of a suitable plastic, e.g. PVC or polypropylene, selected for stiffness similar to or slightly greater than that of disk 14 of the female component. Member 34 has a predetermined diameter approximately that of the through aperture 22, e.g. 2.60 mm, along a neck portion 38 (relatively closer to the base) and a second predetermined diameter, e.g. 3.20 mm, at a distal tip portion 40, the second predetermined diameter being selected to be slightly greater than the diameter of aperture portion 22 to provide an interference fit.

The geometry of the component pieces, and the resilient nature of the materials of fabrication, provide for secure attachment of the charm 18 to the shoe 10. Member 34 is pushed into aperture 22 of female component 12 by application of axially directed force (arrow A) so that distal tip portion 40 stretches aperture 22 until it "snaps" into aperture 28, thereby capturing male component 33 into female component 12.

Referring to FIG. 7, a pendant 44 defines a plurality of apertures (not shown), as described above, for receiving decorative charms 18 having corresponding male components. Pendant 44 is shown attached to a chain 46.

Referring also to FIGS. 8 and 9, a bracelet 48 and barrette 50, respectively, include female components 12, (e.g. molded-in or attached) for receiving charms 18.

Other embodiments are within the scope of the following claims. For example, disc 14 may be any flat shape, and may be attached to shoe 10, e.g., by stitching or adhesive. The female component 12 may also be secured to other parts of shoe 10, including the tongue and rear portions of the upper. The female component may have a body formed of a rigid material, e.g. hard plastic or metal, with a body portion insert of resilient material defining the attachment aperture.

It will also be appreciated that the invention may be employed with any of a variety of types of footwear, including, by way of example only, casual shoes, sandals, sneakers, hiking boots, rain boots and the like.
