ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a fabric strap retainer, and more particularly to a fabric strap retainer that has two engagement units and two release holes for receiving inserted fabric straps between a locking position and an unlocking position.
Fabric straps are extensively used in shoes, bags, and any of a variety of personal articles for securing two parts together. When a fabric strap is inserted through the eyelets on two flaps of a shoe, the two distal ends of the fabric strap are tied up to secure the flaps together. However the fabric strap may be loosened easily during activity of the user.
Further,
FIG. 12
shows a cord member guide block for use with a shoe or the like according to Taiwan patent publication no. 279324, filed on Jan. 28, 1995 by the present inventor. This cord member guide block comprises a body A, and a roller B. The body A comprises a receiving unit A
1
adapted to receive a fabric cord or strap, and a mounting unit A
2
integral with the periphery of the receiving unit A
1
and adapted for mounting. The roller B is rotated in the receiving unit A
1
, and adapted to guide movement of the fabric cord or strap inserted through the receiving unit A
1
. This cord member guide block cannot lock the inserted fabric cord or strap in position.
FIG. 13
shows a fabric cord member (strap) retainer according to Taiwan Patent Publication No. 369821, which is also an invention of the present inventor. This fabric cord member (strap) retainer comprises a body C, which comprises a casing C
1
and a cord member (strap) receiving unit C
2
, a locking lever F pivoted to the body C, and a torsional spring E installed in the body C and connected between the locking lever F and the casing C
1
. The locking lever F has a finger strip F
1
at one end, and a toothed portion F
2
at an opposite end. When assembled, the locking lever F is turned between the locking position where the inserted cord members or straps are closed, and the unlocking position where the inserted cord members or straps are unlocked and can be moved relative to the casing C
1
. This fabric cord member retainer is functional. However because this fabric cord member (strap) retainer is comprised of a number of parts, its fabrication cost is high.
SUMMARY OF THE INVENTION
The invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a fabric strap retainer, which is inexpensive to manufacture.
