ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a shoe accessory, more particularly to a shoelace fastener for maintaining a tightened state of a shoe.
2. Description of the Related Art
In U.S. Pat. No. 6,571,438, there is disclosed a double-bow shoelace device that is adapted to be mounted on a shoe and that includes a shoelace, a clamp member, and an assembly of two loops and a decorative knot. The shoelace has a first lace segment that is strung on the shoe, and a second lace segment that includes first and second lace portions, each of which has a lower end connected to the first lace segment. The clamp member is sleeved slidably on at least one of the lace portions, and includes an elongate casing, a clamping block slidably received in the casing, and a biasing member disposed in the casing for biasing the clamping block to a lace clamping position. Downward and upward movements of the clamp member along at least one of the lace portions result in tightening and loosening of the shoe. The assembly is disposed on and externally of the clamp member.
Although the aforesaid shoelace device serves the purpose of tightening and loosening of the shoe, there are some drawbacks associated therewith. Particularly, because the clamping block of the clamp member must be forced inwardly into the casing against the biasing action of the biasing member when it is desired to loosen the shoe, the overall size of the clamp member must be large enough for the fingers of the user to press the clamping block and the clamp member toward each other. The relatively large clamp member has an adverse affect on the appearance of the shoe. It is also noted that the assembly of the loops and the knot on the clamp member is merely for decorative purposes, and does not have any practical function associated therewith.
FIG. 1

for a shoelace

having a pair of distal lace portions

. The fastener
3
includes a plate body formed with an inner pair of lace entry holes
301
and an outer pair of lace exit holes
302
. Two resilient clamp members
303
extend integrally from the plate body into the lace exit holes
302
, respectively. In use, the distal lace portions
402
are first extended through the lace entry holes
301
and are subsequently extended through the lace exit holes
302
. The clamp members
303
clamp the distal lace portions
402
against the plate body of the fastener
3
. Although the aforesaid shoelace fastener
3
also serves the purpose of tightening and loosening of a shoe (not shown), there are still some drawbacks associated therewith. Particularly, since the fastener
3
must be pulled upwardly when it is desired to loosen the shoe, the lack of a pull component on the fastener
3
makes it difficult to conduct the pulling operation. Moreover, the size of the fastener
3
must be relatively large in order to facilitate upward pulling of the same.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a shoelace fastener that can overcome the aforesaid drawbacks associated with the prior art.
According to the present invention, there is provided a shoelace fastener for a shoe that includes a shoe body with a pair of eyelet tabs, and a shoelace strung on the eyelet tabs and having a pair of distal lace segments. The shoelace fastener comprises a fastener body, a pair of clamp members, and a pull unit secured on and disposed externally of the fastener body.
The fastener body is formed with a pair of through holes that are arranged in a first direction. Each of the through holes has a hole axis transverse to the first direction. Each of the clamp members has a pivot portion pivotable relative to the fastener body about a respective pivot axis that extends in a second direction transverse to the first direction and the hole axes. The pivot portion of each of the clamp members partitions the respective one of the through holes into a lace entry side and a lace exit side respectively proximate to and distal from the other of the through holes. Each of the clamp members further has a clamp portion that extends from the pivot portion.
In use, each of the distal lace segments is extendable through the lace entry side of a respective one of the through holes, over a respective one of the clamp members, and into the lace exit side of the respective one of the through holes. Tension applied by the eyelet tabs upon the shoelace forces the clamp members to clamp the distal lace segments against the fastener body for maintaining a tightened state of the shoe. A manual pulling force applied on the fastener body through the pull unit results in relative movement between the fastener body and at least one of the clamp members to permit sliding movement of at least one of the distal lace segments for loosening the shoe accordingly.
