Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a pad structure for a baby
stroller, and especially to a soft inflatable pad means mounted on
a baby stroller to increase elasticity of the baby stroller.
[0003] 2. Description of the Prior Art
[0004] A baby stroller mainly is for seating therein a baby,
thereby pads for the baby stroller are the most key matters that
influence comfort of a baby seating therein. Pads for a baby
stroller lacking elasticity will make the little baby
uncomfortable; a comfortable pad is thereby an important factor in
selecting and purchasing a baby stroller.
[0005] As shown in FIGS. 1 and 2, a conventional baby stroller A
has on a pad B thereon a plurality of raised strips C filled
therein with soft fillers D of puff sponges, resinous sponges etc.
of high densities, thereby the pad B is endued with appropriate
elasticity to give considerable comfort for a baby seating therein.
However, the soft fillers D formed of puff sponges, resinous
sponges etc. of high densities are inferior in ventilating, heat
generated by a baby seating for a long time therein is unable to
exhaust effectively, hence the heat converts into moisture and
stays in the soft fillers D to make discomfort of the baby; the
puff sponges or resinous sponges etc. of high densities are
subjected to curing by long-time pressing, the elasticity owned by
the soft fillers D originally will lose, and the soft fillers D
will become short of comfort.
[0006] More over, in manufacturing a conventional baby stroller,
soft fillers of puff sponges are placed into the pad; the lateral
sides of a plurality of raised strips are sewn up with a sewing
machine to envelop the soft fillers in the pad to endue the latter
with elasticity. This mode of manufacturing is quite complicated,
and consumes considerable time too; it really does not meet
economic efficiency. In washing the pad, the soft fillers are
subjected to absorbing moisture, and are uneasy to be dried in air;
this induces inconvenience of washing. In view of the above stated
defects, most consumers do not wash their pads customarily; and
more, if a baby has milk or beverage on a baby stroller, the milk
or beverage often drops onto the pad on the stroller to make the
latter dirty and bacteria may breed, this is a big problem
indeed.
SUMMARY OF THE INVENTION
[0007] Therefore, the inventor of the present invention considered
that the above stated problems resided in conventional baby
strollers must be solved, he developed a pad structure for a baby
stroller based on his professional experience of years in studying,
designing and manufacturing same kind of products and after hard
study, developing, as well as repeated experiments and tests, in
order to get rid of the above stated problems.
[0008] In particular, the pad structure for a baby stroller of the
present invention mainly is composed of a piece of lining cloth and
a plurality of soft pads; wherein the lining cloth has two inner
receiving pockets, the soft pads include a backrest pad and a seat
pad to be received respectively in the two inner receiving pockets
of the lining cloth, the backrest pad and the seat pad form
respectively at least an airway, the airways respectively have air
faucets for aeration, the backrest pad and the seat pad thereby
have appropriate elasticity to form good and cozy cushions for the
baby stroller leaning thereon as the primary object of the present
invention.
[0009] The secondary object of the present invention is: the
airways are provided at suitable locations thereon with hot pressed
points mainly for avoiding raising of the central areas of the
airways by overlarge length of the airways, to thereby keep
flatness and tidiness of the airways after aeration.
[0010] Another object of the present invention is: the lining cloth
of the baby stroller has magic tapes to allow the lining cloth
openable, and the inner pockets provide spaces for receiving and
taking out of the backrest pad and the seat pad, so that the latter
can be aerated or changed after taking out, and the lining cloth is
easy for washing to keep the elasticity as well as cleanness of the
soft pads and the lining cloth.
[0011] Moreover, the backrest pad and the seat pad can be provided
with a plurality of fixing holes, and the lining cloth can be
provided at corresponding positions to those of the fixing holes
with a plurality of magic tapes or buttons including an upper and a
lower part each, so that the magic tapes or buttons can be extended
through the fixing holes for fastening, and the backrest pad and
the seat pad can be positioned on the lining cloth to endue the pad
with flatness and tidiness and convenience for folding as well as
to increase esthetic appearance of the pad structure.
[0012] The present invention will be apparent in its contents and
the effects to be achieved after reading the detailed description
of the preferred embodiment thereof in reference to the
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] Referring to FIGS. 3 and 4, the pad structure for a baby
stroller of the present invention comprises mainly a piece of
lining cloth 10 and a plurality of soft pads 20. Wherein the lining
cloth 10 has inner pockets; the soft pads 20 include a backrest pad
21 and a seat pad 22 able to be manufactured separately or to be
manufactured integrally, to thereby be received respectively in the
inner receiving pockets of the lining cloth 10. The backrest pad 21
and the seat pad 22 are sealed, and are closed by pressing to form
a plurality of hot pressed strips 23 by hot pressing, and form
respectively at least an airway 24. The airways 24 of the backrest
pad 21 and the seat pad 22 respectively have air faucets 25 at
suitable locations thereon to be used for aeration with a simple
aerating tool to adjust the air in the pad structure in pursuance
of ones own decision, so that the backrest pad 21 and the seat pad
22 can be endued with appropriate elasticity. Andwhen
inpracticingof the present invention, the backrest pad 21 and the
seat pad 22 can be respectively divided into two mutually separated
airways 24 aerated independently, and the airways 24 are both be
provided with air faucets 25, so that the airways 24 can get the
effect of aeration with these independent air faucets 25.
Therefore, when any of the airways 24 has air leakage or is out of
work by undue using, the other airway 24 can support the weight of
the baby leaning thereon to get an effect of complementarity, and
elasticity of the backrest pad 21 and the seat pad 22 can be
maintained.
[0024] The backrest pad 21 can further be divided into a head
leaning section 211 and a waist leaning section 212. The head
leaning section 211 has two hot pressed strips 23 near the central
area thereof; the two lateral sides thereof are higher than the
central area, so that the head of the baby leaning on the head
leaning section 211 will not move sidewards and hence an effect of
protecting the head of the baby is attained. The two lateral areas
on the backrest pad 21 neighboring to the waist leaning section 212
have two slightly raised protruding portions 213 which are made
according to human body engineering, so that the baby can be cozier
in seating.
[0025] Referring again to FIGS. 4 and 5, the air faucets 25 can
alternatively be provided on two neighboring areas at a lateral
side (as is the case shown in FIG. 5). The airways 24 are provided
at suitable locations thereon with a plurality of hot pressed
points 26 and fixing holes 27; the hot pressed points 26 divide the
airways 24 into several mutually communicating sections, so that
the surface of the airways 24 can get an effect of being flat and
tidy to avoid raising of the central areas of the airways 24 by
overlarge length of the airways 24 to induce unflatness and
untidiness of the surface of the pad structure that may influence
coziness provided by the pad structure.
[0026] As shown in FIGS. 6 and 7, the lining cloth 10 has at
corresponding positions to those of the fixing holes 27 (the
present invention takes the seat pad as an example for explanation)
a plurality of buttons 30 including an upper and a lower part each,
so that the upper and the lower parts of the buttons 30 can be
extended through the fixing holes 27 for fastening. Each button 30
is composed of an upper snap fastener 31 and a lower snap fastener
32; by snap connecting of the upper and the lower snap fasteners
31, 32, the backrest pad 21 and the seat pad 22 can be positioned
on the lining cloth 10.
[0027] Further more, as shown in FIGS. 8 and 9, the lining cloth 10
can also have at corresponding positions to those of the fixing
holes 27 a plurality of magic tapes 40 including an upper and a
lower part each, so that the magic tapes 40 on the lining cloth 10
can be extended through the fixing holes 27 for fastening the upper
and the lower parts thereof, the backrest pad 21 and the seat pad
22 can thus be fixed on the lining cloth 10 to endue the pad
structure with flatness and tidiness, and esthetic appearance as
well as convenience for folding of the pad structure can be
increased.
[0028] Referring to FIG. 10, the backrest pad 21 and the seat pad
22 are provided in the inner pockets of the lining cloth 10 of a
baby stroller 50; the lining cloth 10 is further divided into a
seat section 11 and a leaning section 12. The seat section 11 and
the leaning section 12 are provided respectively with magic tapes
60 in order that the lining cloth 10 can be opened at suitable
locations, thus the inner pockets in the seat section 11 and the
leaning section 12 provide receiving spaces for receiving the seat
pad 22 and the backrest pad 21, so that the latter can be received
in the seat section 11 and the leaning section 12 respectively for
use or for independent use, and the baby stroller 50 can get good
elasticity.
[0029] Thereby, taking advantage of the openable and closable
lining cloth 10, the backrest pad 21 and the seat pad 22 can be
taken out of the seat section 11 and the leaning section 12 for
aeration at any time. The lining cloth 10 can be washed separately
after taking out to maintain cleanness of the lining cloth 10; and
the backrest pad 21 and the seat pad 22 can be used or changed
independently, it needs not to change for a whole new baby stroller
just because of breakage of the backrest pad 21 or the seat pad 22.
Thereby, the life of use of the baby stroller 50 can be
increased.
[0030] The names of the members composing the present invention are
only for illustrating the technical content of the present
invention, and not for giving any limitation to the scope of the
present invention. It will be apparent that various equivalent
modifications or changes made to the elements of the present
invention without departing from the spirit of this invention shall
also fall within the scope of the appended claims to be protected
of this invention.
