ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a shoe, more particularly to a shoe having a shoe lace device that can be tightened to simulate a double-bow knot.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional shoe
4
comprises a shoe body
41
and a shoe lace device
1
. The shoe body
41
has a pair of eyelet tabs
5
. The shoe lace device
1
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 the shoe body
41
so as to form a criss-cross pattern on the eyelet tabs
5
. 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
4
has a shoe lace device
1
that 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 shoe having a shoe lace device that can be tightened to simulate a double-bow knot.
Accordingly, a shoe of this invention comprises a shoe body and a shoe lace device. The shoe body has a pair of eyelet tabs. The shoe lace device includes: first, second, third, and fourth lace sections, each of which has a lower end and an upper end; a clamp member; and a decorative knot. The lower ends of the first to fourth lace sections are anchored on the shoe body. The upper ends of the first and second lace sections are interconnected to form a first loop. The upper ends of the third and fourth lace sections are interconnected to form a second loop. The clamp member is sleeved slidably on medial portions of the first to fourth lace sections. Downward movement of the clamp member along the first to fourth lace sections brings the lower ends of the first to fourth lace sections closer together for tightening the shoe body. Upward movement of the clamp member along the first to fourth lace sections permits the lower ends of the first to fourth lace sections to move away from each for loosening the shoe body. A decorative knot is secured on and is disposed externally of the clamp member, is disposed between the first and second loops, and has a knot portion and a pair of distal portions extending from the knot portion.
