ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a shoe lace device, more particularly to a double-bow shoe lace device for a shoe.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, in U.S. patent application Ser. No. 09/920,965, filed by the applicant on Aug. 3, 2001, there is disclosed a double-bow shoe lace device
400
for a shoe
500
that includes a pair of eyelet tabs
510
. The shoe lace device
400
comprises a shoe lace
1
having first and second lace segments
11
,
12
, a clamp member
2
, a decorative knot
5
, and a pair of pull members
3
. The first lace segment
11
is adapted to be strung on the shoe
500
so as to form a criss-cross pattern on the eyelet tabs
510
. The second lace segment
12
includes first and second lace portions
121
,
122
, each of which has lower, upper, and medial sections
1211
,
1221
,
1212
,
1222
,
1213
,
1223
. The lower section
1211
,
1221
of each of the lace portions
121
,
122
is connected to the first lace segment
11
so as to be adapted to be anchored on a respective one of the eyelet tabs
510
. The clamp member
2
is sleeved slidably on the medial sections
1213
,
1223
of the lace portions
121
,
122
, and includes an elongate casing
21
having first and second lace holes
211
,
212
, a clamping block
22
having a slot unit
221
that corresponds to the first lace hole
211
, and a biasing member
23
with opposite ends that abut respectively against the clamping block
22
and a rear closed end of the casing
21
. The medial sections
1213
,
1223
of the lace portions
121
,
122
extend through the first lace holes
211
, back into the casing
21
via the second lace holes
212
, and out of the casing
21
via the first lace hole
211
to connect with the knot
5
, thus forming the medial sections
1213
,
1223
of the lace portions
121
,
122
into first and second loops (I, II), respectively. Each of the pull members
3
is mounted slidably on the loop (I, II) of a respective one of the medial sections
1213
,
1223
of the lace portions
121
,
122
. The upper sections
1212
,
1222
of the lace portions
121
,
122
are tied together to form the decorative knot
5
that is connected to the medial sections
1213
,
1223
of the lace portions
121
,
122
and that has a pair of. distal lace ends
51
extending therefrom. The loops (I, II) and the knot
5
with the distal lace ends
51
cooperate to form a double-bow configuration.
In use, when the pull members
3
are pulled apart, the loops (I, II) of the medial sections
1213
,
1223
become larger, forcing the clamp member
2
to slide downwardly along the lace portions
121
, thereby bringing the lower sections
1211
,
1221
of the latter closer together for tightening the shoe
500
. To loosen the shoe
500
, the biasing member
23
of the clamping block
2
is compressed so that the slot unit
221
is aligned with the first lace holes
211
in the casing
21
. At this time, by moving the clamp member
2
upwardly along the lace portions
121
,
122
, the lower sections
1211
,
1221
of the latter can be moved away from each other for loosening the shoe
500
.
Although the aforesaid double-bow shoe lace device
400
can achieve its intended purpose, there is a need to provide a double-bow shoe lace with a more simple and reliable structure.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a double-bow shoe lace device of the aforesaid type with a more simple and reliable structure.
According to the present invention, a double-bow shoe lace device is adapted for use with a shoe having a pair of eyelet tabs. The shoe lace device comprises a shoe lace, two loop assemblies, and a clamp member. The shoe lace has first and second lace segments. The first lace segment is adapted to be strung on the shoe so as to form a criss-cross pattern on the eyelet tabs. The second lace segment includes first and second lace portions. Each of the first and second lace portions has a lower section connected to the first lace segment so as to be adapted to be anchored on a respective one of the eyelet tabs, and an upper section opposite to the lower section. Each of the loop assemblies includes a first loop segment connected to the upper section of a respective one of the first and second lace portions, a second loop segment extending integrally from the first loop segment, and a distal lace segment fixed on the first loop segment. The clamp member is sleeved slidably on the loop assemblies and has the second loop segments of the loop assemblies secured thereto. Downward movement of the clamp member along the first loop segments of the loop assemblies brings the lower sections of the first and second lace portions closer together for tightening the shoe. Upward movement of the clamp member along the first loop segments of the loop assemblies permits the lower sections of the first and second lace portions to move away from each other for loosening the shoe.
