Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to sealing technology and more
particularly, to a sealing strap operable by a zipper slider to
force a first interlocking series of teeth into engagement with a
second interlocking series of teeth and a male engagement portion
of a male engaging member into engagement with a female engagement
portion of a female engaging member, achieving excellent tensile
strength and waterproof effects.
[0003] 2. Description of the Related Art
[0004] A regular zip fastener generally comprises two zipper tapes,
two interlocking series of teeth respectively longitudinally
stitched to the zipper tapes, and a zipper slider movable to force
the two interlocking series of teeth into engagement with each
other, achieving a good tensile strength. However, the waterproof
effect of a zip fastener of this design is poor. If a zip fastener
of this design is used in a waterproof product (waterproof bag,
raincoat, etc.), the waterproof product must provide a water
sealing flap and a buckle for protecting the zip fastener against
outside rainwater.
SUMMARY OF THE INVENTION
[0005] The present invention has been accomplished under the
circumstances in view. It is therefore the main object of the
present invention to provide a sealing strap, which is practical
for use in a waterproof product to achieve excellent tensile
strength and waterproof effects.
[0006] To achieve this and other objects of the present invention,
a sealing strip of the invention comprises a first strap body, a
second strap body, and a zipper slider. The first strap body
comprises aa first base portion, a first lining and a second lining
extending along one lateral side of the first base portion at
different elevations, a first interlocking series of teeth extended
from the first lining and a male engaging member with a male
engagement portion extended from the second lining. The second
strap body comprises a second base portion, a third lining and a
fourth lining extending along one lateral side of the second base
portion, a second interlocking series of teeth extended from the
third lining, and a female engaging member with a female engagement
portion extended from the fourth lining. The zipper slider is
movable to force the first interlocking series of teeth into
engagement with the second interlocking series of teeth and the
male engagement portion of the male engaging member into engagement
with the female engagement portion of the female engaging member to
achieve excellent tensile strength and waterproof effects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIGS. 1-7, a sealing strap in accordance with
the present invention is shown. The sealing strap comprises a first
strap body 1, a second strap body 2 and a zipper slider 3.
[0015] The first strap body 1 comprises a first base portion 11, a
first lining 12 and a second lining 13 respectively extended from
one lateral side of the first base portion 11 at different
elevations, a first interlocking series of teeth 14 longitudinally
arranged along one lateral side of the first lining 12 opposite to
the first base portion 11, and a male engaging member 15
longitduinally extending along one laterail side of the second
lining 13 opposite to the first base portion 11. The male engaging
member 15 is formed integral with one lateral side of the second
lining 13, comprising a male engagement portion 151 longitudinally
extending along one lateral side thereof opposite to the second
lining 13, and two first vertical bearing walls 152 respectively
abutted to the opposing top and bottom walls of the second lining
13 at right angles.
[0016] The second strap body 2 comprises a second base portion 21,
a third lining 22 and a fourth lining 23 respectively extended from
one lateral side of the second base portion 21 at different
elevations, a second interlocking series of teeth 24 longitudinally
arranged along one lateral side of the third lining 22 opposite to
the second base portion 21, and a female engaging member 25
longitduinally extending along one laterail side of the fourth
lining 23 opposite to the second base portion 21. The female
engaging member 25 is formed integral with one lateral side of the
fourth lining 23, comprising a female engagement portion 251
longitudinally extending along one lateral side thereof opposite to
the fourth lining 23, and two second vertical bearing walls 252
respectively abutted to the opposing top and bottom walls of the
fourth lining 23 at right angles.
[0017] The zipper slider 3 comprises two first chain grooves 31
bilaterally disposed in a front bottom side thereof, a first spacer
wall 32 disposed between the two first chain grooves 31, a first
coupling chamber 33 defined in a rear bottom side thereof in
communication with the two first chain grooves 31, two pairs of
first stop ribs 37 respectively disposed in opposing top and bottom
sides at two opposite lateral sides of the first coupling chamber
33, two second chain grooves 34 bilaterally disposed in a front top
side thereof above the first chain grooves 31, a second spacer wall
35 disposed between the two second chain grooves 34, a second
coupling chamber 36 defined in a rear top side thereof in
communication with the two second chain grooves 34, two pairs of
second stop ribs 38 respectively disposed in opposing top and
bottom sides at two opposite lateral sides of the second coupling
chamber 36, a crown 39 located at a top side thereof, and a pull
tab 4 coupled to the crown 39. The first interlocking series of
teeth 14 and the second interlocking series of teeth 24 are
respectively inserted into the first chain grooves 31 and the first
coupling chamber 33, the male engaging member 15 and the female
engaging member 25 are respectively inserted into the second chain
grooves 34 and the second coupling chamber 36.
[0018] When using the sealing strap, bond or stitch the first base
portion 11 of the first strap body 1 and the second base portion 21
of the second strap body 2 to two opposite edges of an opening of a
flexible material 5, as on a raincoat or a bag, and then keep the
first interlocking series of teeth 14 and the second interlocking
series of teeth 24 separately at two opposite sides of the first
spacer wall 32 and also keep the male engaging member 15 and the
female engaging member 25 eparately at two opposite sides of the
second spacer wall 35, thereafter, pull the pull tab 4 to slide the
zipper slider 3 along the gap between the first lining 12 and the
third lining 22 and the gap between the second lining 13 and the
fourth lining 23 from one end to the opposite end. At this time,
the first vertical bearing walls 152 of the male engaging member 15
and the the second vertical bearing walls 252 of the female
engaging member 25 are guided by the first stop ribs 37 to move the
first interlocking series of teeth 14 and the second interlocking
series of teeth 24 toward each other, causing the first
interlocking series of teeth 14 to be interlocked with the second
interlocking series of teeth 24 in the first coupling chamber 33,
and at the same time, the first vertical bearing walls 152 of the
male engaging member 15 and the the second vertical bearing walls
252 of the female engaging member 25 are also guided by the second
stop ribs 38 toward each other, causing the male engagement portion
151 of the male engaging member 15 to be engaged into the female
engagement portion 251 of the female engaging member 25 in the
second coupling chamber 36. At this time, the second lining 13 and
the fourth lining 23 are sealed by the male engaging member 15 and
the female engaging member 25, prohibiting permeation of outside
rainwater through the seal strap. Thus, the invention provides
excellent windproof and waterproof effects, and is practical for
use in a waterproof product such as raincoat or bag. When wishing
to open the two opposite edges of the opening of the flexible
material 5, pull the pull tab 4 in the reversed direction to move
the first spacer wall 32 between the first interlocking series of
teeth 14 and the second interlocking series of teeth 24 and the
second stop ribs 38 between the male engaging member 15 and the
female engaging member 25 subject to the guidance of the first stop
ribs 37 and the second stop ribs 38, causing separation between the
first interlocking series of teeth 14 and the second interlocking
series of teeth 24 and separation between the male engagement
portion 151 of the male engaging member 15 and the female
engagement portion 251 of the female engaging member 25, and thus,
the zipper slider 3 is returned to its original position.
