Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to an inner sole assembly
for slippers or sandals, including a slipper or sandal made up of a
sole, a retaining strap, a coupling pad, and an insole wherein the
sole has a plurality of assembly holes distributed thereon for the
retaining strap to be fixedly engaged therewith, and the coupling
pad is sandwiched between the insole and the top surface of the
sole to integrally combine the insole and the sole into one piece.
The insole has a plurality of resilient supporting rings with air
vents densely and neatly arranged in upright circular shapes at the
upper surface thereon, and a plurality of dividing passages defined
at the adjacent sides of the closely arranged resilient supporting
rings thereof; whereby, in case tiny grains of sands/stones get
caught inside the insole thereof, the sands/stones can be precisely
flushed or knocked out there-from via the air vents of the
resilient supporting rings in an easy and fast manner, achieving
superior effects of massage as well as sand-draining and
air-venting capabilities to prolong the using lifetime thereof.
[0002] Please refer to FIG. 1. A conventional slipper 10 is made up
of a sole 11 having an adhesive glue layer coated at the top
surface thereon for an insole 12 of fiber material to be attached
thereto, and a plurality of engaging through holes 111 disposed at
preset spots thereon for coupling posts 131 of a retaining strap 13
to be fixedly registered therewith. The insole 12 is made up of a
plurality of resilient fibers 121 randomly and sparsely disarranged
and intertwined into a preset thickness with gaps 122 of various
sizes distributed thereon.
[0003] There are some drawbacks to such conventional slipper 10.
First, the gaps 122 of various sizes are formed among the
interwoven resilient fibers 121 of the insole 12 thereof for
air-venting and water-draining effects thereof. Yet, in case tiny
grains of sands/stones A get caught in the gaps 122 as shown in
FIG. 2, the sands/stones A, hard to be flushed or knocked out
there-from, tend to get stuck at the disarranged fibers 121 therein
even if the slipper 10 is overturned for cleaning thereof. After
long time of frequent use thereof, sands/stones A can accumulate
more and more inside the insole 12 thereof and make the slipper 10
uncomfortable and untidy to be worn. Second, the insole 12 is
directly attached to the top surface of the sole 11 thereon, which
tends to have poor fastening effect due to the difference of the
insole 12 and the sole 11 in material and result in the coming off
of the insole 12 if pulled by force from outside. Third, the insole
12 is made up of the irregularly intertwined fibers 121 that can
easily interfere one another and loose the flexibility to rebound
to the original position. Thus, after long tome of use, partial
cavities B are easily indented at the surface of the insole 12
thereon as shown in FIG. 2, which greatly reduce the flexible
effect and the using lifetime of the insole thereof.
SUMMARY OF THE PRESENT INVENTION
[0004] It is, therefore, the primary purpose of the present
invention to provide an inner sole assembly for slippers or
sandals, including a slipper or sandal made up of a sole, a
retaining strap, a coupling pad, and an insole wherein the insole
has a plurality of resilient supporting rings with air vents
densely and neatly arranged in upright circular shapes at the upper
surface thereon, and a plurality of dividing passages defined at
the adjacent sides of the closely arranged resilient supporting
rings thereof; whereby, in case tiny grains of sands/stones get
caught inside the insole thereof, the sands/stones can be precisely
flushed or knocked out there-from via the air vents of the
resilient supporting rings in an easy and fast manner, preventing
the sands/stones from accumulated at the resilient supporting rings
therein, achieving better sand-draining effect to keep the insole
thereof neat and clean in practical use.
[0005] It is, therefore, the second purpose of the present
invention to provide an inner sole assembly for slippers or sandals
wherein the resilient supporting rings of the insole are closely
and neatly stood upright in circular shapes, efficiently sustaining
the weight of the sole of a wearer and providing a massage effect
to the sole stepped downwards along the neatly arranged resilient
supporting rings in practical use. When not in use, the resilient
supporting rings can quickly retract upwards to the original
positions without any partial indents produced thereby, providing
superior effects of massage as well as air-venting and
water-draining capabilities to prolong the using lifetime of the
insole thereof.
[0006] It is, therefore, the third purpose of the present invention
to provide an inner sole assembly for slippers or sandals wherein
the insole can also have bamboo charcoal contained therein;
whereby, the insole thereof is equipped with strong absorbing and
decomposing capabilities as well as anti-bacteria,
humid-adjustment, and deodorization power. Besides, far-infrared
radiation proper for the absorption of human body is generated to
speed up blood circulation and improve the health of human body,
and healthy negative ions is increased in the air to balance the
humidity inside the slipper or sandal and prevent bugs therein,
efficiently promoting the quality of the insole of the slipper or
sandal thereof to achieve better deodorization and anti-bacteria
effects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Please refer to FIG. 3. The present invention is related to
an inner sole assembly for slippers or sandals, including a slipper
or sandal 20 made up of a sole 21, a retaining strap 22, a coupling
pad 23, and an insole 24. The sole 21 has a plurality of assembly
holes 211 properly preset at the top surface thereon for the
retaining strap 22 of a slipper or a sandal as shown in FIG. 6 to
be fixedly engaged therewith, and a holding recess 212 of proper
depth indented at the top surface thereon. The coupling pad 23,
better made of EVA or PVC foaming material, is molded in
conformance to the shape of the holding recess 212 thereof and with
a proper thickness. The insole 24, having bamboo charcoal contained
therein, is integrally woven and shaped like the holding recess 212
thereof. A multiple of resilient supporting rings 242 with air
vents 241 defined therein are densely and neatly arranged and stood
upright in circular shapes at the upper surface of the insole 24
thereon as shown in FIG. 5, and an engaging underside 243 is formed
at the bottom surface of the insole 24 thereof. A plurality of
dividing passages 244 are formed at the adjacent sides of the
neatly juxtaposed resilient supporting rings 242 thereof.
[0014] Please refer to FIGS. 4 to 5 inclusive. In assembly, the
coupling pad 23 is fixedly attached to the engaging underside 243
of the insole 24 at one side thereof before mounted to the holding
recess 212 of the sole 21 at the other side and firmly engaged
therewith via thermo-pressing to generate heat welding and
integrally combine the coupling pad 23 with the holding recess 212
and the sole 21 to achieve better engagement thereby. The retaining
strap 22 is then led through the insole 24 and the coupling pad 24
thereof respectively before fixedly registered with the assembly
holes 211 of the sole 21 for location thereby to complete the
assembly of the slipper or sandal 20 thereof. In practical use, the
resilient supporting rings 242 closely and neatly arranged at the
upper surface of the insole 24 thereon with the dividing passages
244 disposed at the adjacent sides thereof can provide superior
effects of massage, and air venting and water-draining
capabilities. In case tiny grains of sands/stones get caught inside
the insole 24, the sands/stones can be easily and quickly flushed
or knocked out there-from via the air vents 241 of the resilient
supporting rings 242, achieving more precise sand-draining
capability thereof. Via the bamboo charcoal contained therein, the
insole 24 thereof is also equipped with strong absorbing and
decomposing capabilities as well as anti-bacteria,
humid-adjustment, and deodorization power. Besides, far-infrared
radiation proper for the absorption of human body is generated to
speed up blood circulation and improve the health of human body,
and healthy negative ions is increased in the air to balance the
humidity inside the slipper or sandal 20 and prevent bugs therein,
efficiently promoting the quality of the slipper or sandal 20
thereof to achieve better deodorization and anti-bacteria effects
thereof.
