Definitions

  • the present invention relates generally to a metal caps for shoelace tips and a shoelace including the metal caps.
  • Shoelaces are one of the most commonly used fastening devices to fasten shoes onto feet of a human. Generally, before wearing a shoe, a shoelace needs to be pierced sequentially through eyelets formed in the shoe and then a slipknot (such as, a bow-knot) is tied with the two end portions of the shoelace at a position close to a top line of the shoe so as to fasten the shoe to a foot.
  • a slipknot such as, a bow-knot
  • a shoelace 1 is a string of woven fabrics with two hardened and downsized tips 2 for facilitating the piercing operation of the shoelace 1 through the eyelets formed in the shoe, as illustrated in FIG. 1 .
  • a plastic hoop 3 is provided around the tip 2 to prevent the tip from being loosened due to wearing and the like during the use of the shoelace.
  • a protective metal cap 4 is provided to surround the plastic hoop 3 to provide additional protections that the tips of the shoelaces for heave duty shoes need.
  • a traditional metal cap 4 as illustrated in FIG. 2 , is a hollow cylindrical metal cap that has a longitudinal slot 5 formed in a peripheral wall and a number of dents 6 formed in the peripheral wall at positions opposite to the longitudinal slot 5 .
  • the metal cap 4 is fit outside the plastic hoop 3 and then the metal cap 4 is squeezed with a clamping tool (not shown) to radially and circumferentially compress the metal cap 4 and to clamp the metal cap 4 onto the plastic hoop 3 with the dents 6 abutting the plastic hoop's peripheral wall.
  • the traditional metal cap may provide a certain degree of protection to the plastic hoop and to the tip portion of the shoelace, yet a main drawback of the traditional metal cap is that it is easy to separate from the plastic hoop because the bounding between the metal cap and the plastic hoop is not strong enough because it is provided merely by the compression force exerted onto the plastic hoop by the dents of the metal cap, and thus the protection provided by the metal cap no longer exists once it came off from the plastic hoop/tip portion of the shoelace.
  • one object of the present invention is to provide a reliable metal cap that can be firmly attached to the plastic hoop/tip of a shoelace and will not easily come off from the plastic hoop/tip during the service life of the shoelace.
  • Another object of the present invention is to provide a shoelace that has this novel metal cap attached thereon.
  • a metal cap for a shoelace includes a substantially hollow cylindrical body having an inner space and a length in a longitudinal direction that is substantially equal to a length of a tip portion of the shoelace.
  • the cylindrical body includes a substantially closed first end, an open second end opposite to the first end, and a peripheral wall extending from the first end to the second end.
  • the metal cap further includes a fastening mechanism configured to allow the peripheral wall of the body to be circumferentially displaced with respect to the tip portion of the shoelace when subjected to a radial clamping force so as to permit the inner space of the body to be reduced; a first attaching mechanism provided in the peripheral wall of the body and configured to radially engage with a plastic hoop fit on the tip portion of the shoelace when the inner space of the body is reduced; and a second attaching mechanism configured to bit into the shoelace and abut an end edge of the plastic hoop when the inner space of the body is reduced.
  • the fastening mechanism includes a longitudinal slot in the peripheral wall extending substantially from the first end to the second end of the body and defined by a first side edge and a second side edge of the peripheral wall and having a width between the first and second side edges.
  • the peripheral wall further includes a protrusion circumferentially protruding from the first side edge and a notch circumferentially recessed in the second side edge at a position corresponding to the protrusion.
  • the first attachment mechanism includes a number of dents radially inwardly recessed in the peripheral wall.
  • the dents are formed at longitudinally aligned positions opposite to the longitudinal slot.
  • the second attaching mechanism includes a number of teeth radially inwardly protruding from the open second end of the body.
  • the teeth are circumferentially evenly spaced apart from each other at the second end of the body.
  • a shoelace includes: a woven fabrics shoelace body; two tip portions each formed at an end of the shoelace body and having a length; two plastic hoops each fit and secured to one of the tip portions and has a length substantially equal to the length of the tip portion; and two metal caps according to above-mentioned first aspect of the present application each fit and secured to one of the tip portions by means of the engagement between the first attachment mechanism and the plastic hoop and the abutment/engagement between the second attachment mechanism and the plastic hoop/the shoelace body.

  • the metal cap 10 of the present invention comprises the unique structural features described above, the metal cap 10 of the present invention can provide a much stronger bonding between the metal cap and the shoelace. Specifically, for a shoelace having traditional metal caps attached to its tip portions, it usually only requires a force approximately 15 kg to detach the traditional metal cap from the shoelace tip portion. For the metal cap 10 of the present invention on the other hand, according to results obtained from the tests performed by the inventor, it takes up to a force of approximately 25 kg to separate metal cap 10 for the shoelace. That is, the metal cap of the present invention can provide at least 60% higher bonding capability than the traditional metal caps can, and this in turn can provide the shoelace a even longer effective service life. Therefore, the metal cap and the shoelace having the metal cap of the present invention are creations that have a great industrial applicability.
