  • [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.

  • 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.
