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
FIG. 1
, a conventional shoe lace device
1
of a shoe
4
includes a shoe lace
2
having first and second lace sections
201
,
202
, and a clamp member
3
. The first lace section
201
is strung on a shoe body
41
so as to form a criss-cross pattern on eyelet tabs
5
of the shoe body
41
. The second lace section
202
is formed as a simple loop, and has lower ends
2021
connected to the first lace section
201
, thereby anchoring the lower ends
2021
on the eyelet tabs
5
, respectively. The clamp member
3
, as shown in
FIG. 2
, includes an elongate casing
301
, a clamping block
302
, and a spring member
303
. The elongate casing
301
is formed with a lateral open end
3010
for receiving the clamping block
302
, a closed end
3011
opposite to the open end
3010
, and a vertically extending hole unit
301
′ for extension of the lower ends
2021
of the second lace section
202
therethrough. The clamping block
302
is slidably received in the open end
3010
of the casing
301
, and is formed with a vertically extending slot unit
3021
that corresponds to the hole unit
301
′ of the casing
301
for extension of the lower ends
2021
of the second lace section
202
therethrough. The spring member
303
is disposed in the casing
301
, and has opposite ends that abut respectively against the clamping block
302
and the closed end
3011
of the casing
301
. As such, the clamping block
302
is biased by the spring member
303
so as to misalign the slot unit
3021
from the hole unit
301
′ in order to clamp the second lace section
202
between the clamping block
302
and the casing
301
.
To tighten the shoe
4
, the clamp member
3
is forced to move downwardly along the second lace section
202
, thereby bringing the lower ends
2021
of the second lace section
202
closer together.
To loosen the shoe
4
, the clamping block
302
is operated to align the slot unit
3021
with the hole unit
301
′ against action of the spring member
303
, and the clamp member
3
is then moved upwardly along the second lace section
202
, thus permitting the lower ends
2021
of the second lace section
202
to move away from each.
Although the aforesaid shoe lace device
1
is easy to use, the simple loop configuration of the second lace section
202
has an unattractive appearance.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a double-bow shoe lace device for a shoe.
Accordingly, a double-bow shoe lace device of this invention is adapted for use with a shoe having a pair of eyelet tabs and a tongue between the eyelet tabs. The shoe lace device comprises a shoe lace, a clamp member, and a positioning unit. The shoe lace has first, second and third lace portions, each of which has a lower end and an upper end. The lower ends of the first and second lace portions are adapted to be anchored on a respective one of the eyelet tabs. The upper ends of the first and third lace portions are tied together to form a knot and a pair of distal lace segments that extend from the knot. The clamp member is sleeved slidably on a medial section of the first lace portion between the lower and upper ends of the first lace portion. The lower end of the third lace portion and the upper end of the second lace portion are anchored on the clamp member. The positioning unit is connected to the knot and the clamp member, and positions the knot on the clamp member such that the medial section of the first lace portion and the third lace portion form first and second loops between the knot and the clamp member.
