Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority of Taiwanese Patent
Application No. 102223914, filed on Dec. 18, 2013.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to a raincoat having a waterproof
zipper unit, more particularly to a raincoat having a waterproof
unit with a bonding tape interfused with a raincoat main body
through hot melt or high-frequency welding techniques.
[0004] 2. Description of the Related Art
[0005] A conventional raincoat includes a raincoat main body having
two foreparts, and a zipper used to link the foreparts. The zipper
includes two zipper halves, each of which has a fabric tape.
Generally, fixing of the fabric tape of the zipper to the raincoat
main body is conducted using sewing techniques. However, the sewing
techniques may result in formation of tiny holes extending through
the fabric tape and the raincoat main body. As a consequence,
rainwater may penetrate through these holes.
SUMMARY OF THE INVENTION
[0006] Therefore, an object of the present invention is to provide
a raincoat that can overcome the aforesaid drawback associated with
the prior art.
[0007] According to the present invention, there is provided a
raincoat that comprises: a raincoat main body including a first
forepart and a second forepart spaced apart from the first
forepart, the first and second foreparts being made from a first
waterproof polymeric material that is heat-meltable or
high-frequency-weldable; and a zipper unit including two zipper
halves, each of which has a fabric tape, a plurality of chain teeth
secured to the fabric tape, a hot-melt adhesive bonded to the
fabric tape, and a bonding tape bonded to the fabric tape through
said hot-melt adhesive. The bonding tape is made from a second
waterproof polymeric material that is heat-meltable or
high-frequency-weldable. The bonding tape of each of the zipper
halves and a corresponding one of the first and second foreparts
are interfused together through hot melt or high-frequency welding
techniques.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] In drawings which illustrate an embodiment of the
invention,
[0009] FIG. 1 is a perspective view of the preferred embodiment of
a raincoat according to the present invention;
[0010] FIG. 2 is a front view of the preferred embodiment
illustrating a state where zipper halves of a zipper unit are
secured together;
[0011] FIG. 3 is a rear view of the preferred embodiment; and
[0012] FIG. 4 illustrates consecutive steps of hot melting or
high-frequency welding a bonding tape to a forepart of the raincoat
of the preferred embodiment.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] FIGS. 1 to 3 illustrate the preferred embodiment of a
raincoat according to the present invention.
[0014] The raincoat includes a raincoat main body 3 and a zipper
unit 7, and is formed with an opening 310. The raincoat main body 3
includes a back part 31, a first forepart 32, a second forepart 33
spaced apart from the first forepart 32, a fly 34, a hood 35, and
first and second sleeves 36, 37. The first and second foreparts 32,
33 are respectively connected to two sides of the back part 31. The
first and second foreparts 32, 33 and the back part 31 are made
from a first waterproof polymeric material that is heat-meltable or
high-frequency-weldable. The opening 310 is formed in the back part
31. The first and second sleeves 36, 37 are respectively connected
to the first and second foreparts 32, 33.
[0015] As shown in FIGS. 1 and 4, the zipper unit 7 includes two
zipper halves 71, each of which has a fabric tape 711, a plurality
of chain teeth 712 secured to the fabric tape 711, a hot-melt
adhesive 713 bonded to the fabric tape 711, and a bonding tape 714
bonded to the fabric tape 711. The bonding tape 714 is made from a
second waterproof polymeric material that is heat-meltable or
high-frequency-weldable. The bonding tape 714 of each of the zipper
halves 71 and a corresponding one of the first and second foreparts
32, 33 are interfused together through hot melt or high-frequency
welding techniques to form a welding area 700.
[0016] FIG. 4 illustrates consecutive steps of fixing one of the
zipper halves 71 to the first forepart 32. The bonding tape 714 is
bonded to a surface of the fabric tape 711 through the hot melt
adhesive 713, followed by attaching and bonding the bonding tape
714 to the first forepart 32 using high-frequency welding
technique. During the welding process, the bonding piece 714 and
the first forepart 32 are welded together, and the hot-melt
adhesive 713 is hot-melted and penetrates through the fabric tape
711 and the bonding tape 714.
[0017] Since the first and second waterproof polymeric materials
are both heat-meltable or both high-frequency-weldable, a contact
area between the bonding tape 714 and the first forepart 32 is free
of holes, thereby eliminating the aforesaid drawback associated
with the prior art. Furthermore, the bonding strength between the
bonding tape 714 and the first forepart 32 is considerably
enhanced.
[0018] Preferably, each of the first and second waterproof
polymeric materials is selected from polyethylene (PE),
polyvinylchloride (PVC), nylon, ethylenevinyl acetate (EVA),
polyethylene vinyl acetate (PEVA) and combinations thereof. More
preferably, each of the first and second waterproof polymeric
materials is selected from ethylene vinyl acetate, polyethylene
vinyl acetate and the combination thereof. Most preferably, the
first and second waterproof polymeric materials are the same.
[0019] The raincoat main body 3 further includes a ventilation mesh
4 that covers the opening 310 and that is fixed to the raincoat
main body 3, and a flap sheet 5 that has an edge 51 fixed to the
raincoat main body 3 so as to be swingable relative to the raincoat
main body 3 for covering and uncovering the ventilation mesh 4. The
flap sheet 5 cooperates with the ventilation mesh 4 to define
therebetween a ventilation gap 50 for passage of sweat vapor
therethrough when the flap sheet 5 covers the ventilation mesh
4.
[0020] The position of the opening 310 is not limited to the
disclosure of this embodiment. The opening 310 maybe formed in one
of the first and second foreparts 32, 33, and the positions of the
ventilation mesh 4 and the flap sheet 5 would be changed
accordingly.
[0021] As shown in FIGS. 1 and 2, the raincoat further includes at
least one bonding unit 6. The bonding unit 6 includes a first
fixing element 61 fixed to a top end of the first forepart 32, an
extension band 62 fixed to the second forepart 33 and movable to
cross the zipper unit 7, and a second fixing element 63 fixed at an
end portion of the extension band 62 and engageable with the first
fixing element 61.
[0022] In this embodiment, the first and second fixing elements 61,
63 are male and female buttons, respectively.
[0023] While the present invention has been described in connection
with what is considered the most practical and preferred
embodiment, it is understood that this invention is not limited to
the disclosed embodiment but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretation so as to encompass all such modifications and
equivalent arrangements.
