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 co-pending U.S. patent application Ser. No. 09/920,946, filed by the applicant on Aug. 8, 2001, there is disclosed a double-bow shoe lace device
1
of a shoe
5
that includes a shoe lace
4
having first and second lace segments
41
,
42
, a clamp member
2
, and an assembly
3
of two loops
302
and a decorative knot
301
. The first lace segment
41
is strung on a shoe body
501
so as to form a criss-cross pattern on eyelet tabs
504
of the shoe body
501
. The second lace segment
42
includes first and second lace sections
421
,
422
. The lace sections
421
,
422
have lower ends
4211
,
4221
connected to the first lace segment
201
so as to be anchored respectively on the eyelets
503
of the eyelet tabs
504
, and upper ends
4212
,
4222
extending through the clamp member
2
. The clamp member
2
includes an elongate casing
201
, a clamping block
202
slidably received in the casing
201
, and a biasing member
203
disposed between the clamping block
202
and the casing
201
. The decorative knot
301
of the assembly
3
is disposed on top of the casing
201
. Each of the loops
302
extends out of the casing
201
to connect with the knot
301
. The assembly
3
is thus secured on the clamp member
2
. The upper ends
4212
,
4222
of the lace sections
421
,
422
form distal lace segments
4214
,
4224
which cooperate with the assembly
3
to form a double-bow configuration.
In use, by pulling apart the distal lace segments
4214
,
4224
, the clamp member
2
will be forced to slide downwardly along the lace sections
421
,
422
, thereby bringing the lower ends
4211
,
4221
of the lace sections closer together for tightening the shoe
5
. To loosen the shoe
5
, the clamping block
202
is operated to compress the biasing member
203
, and the clamp member
2
is moved upwardly along the lace sections
421
,
422
, there by moving the lower ends
4211
,
4221
of the lace sections
421
,
422
away from each other for loosening the shoe
5
.
Although the aforesaid double-bow shoe lace device
1
can achieve its intended purpose, there is a need to provide a double-bow shoe lace device 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 one aspect of this invention, a double-bow shoe lace device for a shoe with a pair of eyelet tabs 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 sections, each of which has a lower end 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 end. Each of the loop assemblies includes a distal lace segment, an inverted U-shaped lace segment, and a fastening unit. The inverted U-shaped lace segment has a first end connected to the distal lace segment, and a second end connected to the upper end of a respective one of the first and second lace sections. The fastening unit fastens together the distal lace segment and the first and second ends of the inverted U-shaped lace segment. The clamp member is sleeved slidably on the loop assemblies. Downward movement of the clamp member along the loop assemblies brings the lower ends of the first and second lace portions closer together for tightening the shoe. Upward movement of the clamp member along the loop assemblies permits the lower ends of the first and second lace portions to move away from each other for loosening the shoe.
According to another aspect of this invention, a double-bow shoe lace device for a shoe with a pair of eyelet tabs comprises a shoe lace, a first loop assembly, a second loop assembly, 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 sections. Each of the first and second lace sections has a lower end 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 end. The first loop assembly includes a first distal lace segment, a first inverted U-shaped lace segment having a first end connected to the first distal lace segment, and a second end connected to the upper end of the first lace section, and a fastening unit for fastening together the first distal lace segment and the first and second ends of the first inverted U-shaped lace segment. The second loop assembly includes a second distal lace segment, a second inverted U-shaped lace segment having first and second ends, and a decorative knot connected to the second distal lace segment, the first and second ends of the second inverted U-shaped lace segment, and the upper end of the second lace section. The clamp member is sleeved slidably on the first loop assembly, and permits the upper end of the second lace section to extend therethrough. Downward movement of the clamp member along the first loop assembly brings the lower ends of the first and second lace sections closer together for tightening the shoe. Upward movement of the clamp member along the first loop assembly permits the lower ends of the first and second lace sections to move away from each other for loosening the shoe.
