Abstract
A shoelace anglet having a front opening at one end thereof, a rounded head at an opposite end thereof, an end slot in the rounded head, a split extended between the end slot and the front opening, at least one protruding portion disposed at a first side of the split, and at least one recessed portion disposed at a second side of the split and adapted to receive the at least one protruding portion respectively.
Description
BACKGROUND OF THE INVENTION
The present invention relates to shoelaces and, more particularly, to anglets for shoelaces, which are prohibited from hooking up with each other when installed in the ends of the shoelace of a shoe.
Conventional shoelace anglets are commonly injection-molded from plastics. During installation, the shoelace anglet is internally covered with a layer of acetone, and then attached to the end of the shoelace, and then fixedly secured thereto by a heat press. This structure of plastic anglet is not durable in use, and tends to be removed from the shoelace when stretched. In order to eliminate these drawbacks, metal shoelace anglets are developed. A regular metal shoelace anglet comprises a front opening at one end, a rounded head at the other end, a crossed end slot in the rounded head, and a longitudinal split extended between the crossed end slot and the front opening. This structure of metal shoelace anglet is durable in use. However, the metal shoelace anglets may hook up with one another when put together during after fabrication or during surface treatment.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a metal shoelace anglet, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide shoelace anglets for shoes, which are easy and inexpensive to manufacture. It is another object of the present invention to provide shoelace anglets for shoes, which are durable in use. It is still another object of the present invention to provide shoelace anglets for shoes, which do not hook up with one another when put together. According to the present invention, the shoelace anglet has a front opening at one end thereof, a rounded head at an opposite end thereof, an end slot in the rounded head, a split extended between the end slot and the front opening, at least one protruding portion disposed at a first side of the split, and at least one recessed portion disposed at a second side of the split and adapted to receive the at least one protruding portion respectively. Because the at least one protruding portion respectively project into the at least one recessed portion, shoelace anglets do not hook up with one another when put together.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
illustrates two shoelace anglets hooked up with each other according to the prior art.
FIG. 2
is an elevational view of a shoelace anglet according to a first embodiment of the present invention.
FIG. 3
is a plain view of the shoelace anglet shown in FIG.
2
.
FIG. 4
is an elevational view of an alternate form of the shoelace anglet according to the present invention.
FIG. 5
is an elevational view of another alternate form of the shoelace anglet according to the present invention.
FIG. 6
is an elevational view of still another alternate form of the shoelace anglet according to the present invention.
FIG. 7
is an elevational view of still another alternate form of the shoelace anglet according to the present invention.
FIG. 8
is an elevational view of still another alternate form of the shoelace anglet according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG.
2
˜
3
, an anglet in accordance with the present invention comprises a metal anglet body
1
shaped like an elongated, cylindrical, split cap. The anglet body
1
has a front opening
11
at one end, a rounded head
12
at the other end, an end slot of any of a variety of shapes, for example, a crossed end slot
121
in the rounded head
12
, and a split
13
extended between the crossed end slot
121
and the front opening
11
. Further, a protruding portion
14
and a recessed portion
15
are respectively formed integral with the anglet body
1
at two sides of a curved part
10
of the split
13
near the front opening
11
. The protruding portion
14
projects into the recessed portion
15
. Because the protruding portion
14
is engaged into the recessed portion
15
, shoelace anglets do not hook up with one another when put together.
The aforesaid protruding portion
14
and recessed portion
15
are a good match, and can be made having any of a variety of shapes, for example, the rectangular shape shown in
FIGS. 2 and 3
, the smoothly arched shape shown in
FIG. 4
, the triangular shape shown in
FIG. 5
, or the trapezoidal shape shown in FIG.
7
.
FIG. 6
shows still another alternate form of the present invention. According to this alternate form, the anglet body
1
comprises a front opening
11
at one end, a rounded head
12
at the other end, an end slot of any of a variety of shapes, for example, a crossed end slot
121
in the rounded head
12
, a split
13
extended between the crossed end slot
121
and the front opening
11
, a first hooked protruding portion
14
and a recessed portion
15
respectively disposed at two sides of a curved part
10
of the split
13
, and a second hooked protruding portion
14
suspending in the recessed portion
15
and hooked up with the first hooked protruding portion
14
.
FIG. 8
shows still another alternate form of the present invention. According to this alternate form, two protruding portions
14
and two recessed portions
15
are symmetrically disposed at two sides of a respective curved part
10
of the split
13
.
A prototype of shoelace anglet has been constructed with the features of FIGS.
1
˜
8
. The shoelace anglet functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
