Aglet

Inventions related to shoelaces have been described in the prior art patent literature.

For example, U.S. Pat. No. 7,549,201 discloses that an elastic shoelace includes a first end and a second end, an elongate elastic core, a sheath, and an elongate friction member. The elongate elastic core extends between the first and second ends of the elastic shoelace, and the sheath includes an outer surface and surrounds the elongate elastic core. The elongate friction member is disposed in the sheath, and at least a portion of the elongate friction member protrudes past the outer surface of the sheath.

U.S. Pat. No. 8,931,146 discloses a tying lace constructed of an outer braided cover having a first thread type and a second thread type. The second thread type is formed from a different material and/or has a different cross-sectional area than the first thread type. In an exemplary embodiment, the cross-sectional area is at least twice that of the first thread type. Additionally, the second thread type may be of a material having higher elastic properties and/or a greater coefficient of friction than the first thread type. Further, in an exemplary embodiment, the tying lace is constructed with an elastic core extending the length of the tying lace.

US20050257355 discloses aglet and aglet designs that facilitate the threading of lace material through eyelets or over tabs or spike located on active footwear. Preferably, the aglet of the present invention has a curved, tapering shape and includes an apex, a neck, and differing inner and outer axes of curvature which converge at the apex. In another embodiment the aglet has a continuously tapering shape. In one preferred embodiment, a tangent line to the outer axis of curvature changes from the neck to the apex through less than about 45 degrees and, most preferably, through about 30 degrees.

Nevertheless, existing designs for shoelaces and shoelace tips knowns as aglets suffer from limitations including lack of durability and lack of versatility.

Therefore, the present invention provides an aglet which combines a screw on the end of a shoelace and a charm which is configured to attach securely to the screw.

According to an aspect of the present invention, there is provided an aglet, comprising: a screw on the end of a shoelace; and a charm, wherein: the screw is configured to insert inside a recess in the charm and tighten to secure the charm to the shoelace.

According to another aspect of the present invention, there is provided a method of attaching a charm to a shoelace, comprising: providing a screw on the end of a shoelace; providing a charm having a recess configured to receive the screw; inserting the screw inside the charm; and twisting the charm around the screw to tighten.

Prior art aglets are generally a sheath, often made of plastic or metal, attached at each end of a shoelace, a cord, or a drawstring. The aglet keeps the fibers of the lace or cord from unraveling; its firmness and narrow profile make it easier to hold and easier to feed through eyelets, lugs, or other lacing guides.

However, the prior art aglets are prone to falling off and lack durability. As well, they lack ability to easily be decorated or otherwise display an aesthetic.

The aglet of present invention is both functionally superior and fashionable. Embodiments of the aglet of the present invention will be described with reference to the appended drawings.
