JP 2003-175827 A

  Japanese Patent Laying-Open No. 2003-175827 discloses a baby carriage that can be tilted backward until the backrest is substantially horizontal. In the case of the baby carriage having such a bed shape, it is necessary to consider a thermal environment caused by reflection from asphalt or concrete road surface particularly in summer.

  According to a survey conducted by the applicant of the present application, when the baby carriage is pushed in the form of a bed on the asphalt surface at around 2 pm on a sunny day in summer, the temperature of the infant's face is The temperature reached 36.4 ° C, 5.5 degrees higher than the temperature. This was 3.5 degrees higher than the temperature of the adult face position of the person pushing the baby carriage. When the baby carriage was stopped, the temperature of the infant's face became even higher, and the temperature difference from the adult's face exceeded 4 degrees.

  As is clear from the above survey results, it is desirable to take measures against radiant heat from the road surface particularly in the case of a stroller having a bed shape.

  An object of the present invention is to provide a baby carriage capable of adjusting the air permeability of a seat forming member and preventing radiant heat from a road surface.

  The baby carriage according to the present invention includes a seat forming member having a ventilation opening, a reflecting member, and a holding means. The reflection member is provided so as to be selectively changeable between a first position located close to the back surface of the seat forming member and a second position located away from the back surface of the seat forming member. The outer surface facing away forms a reflective surface. The holding means holds the reflecting member so that the position can be changed. When the reflecting member is in the first position, the ventilation opening is closed, and when the reflecting member is in the second position, the ventilation opening is opened.

  According to the present invention having the above-described configuration, the reflective surface of the reflecting member reflects the radiant heat from the road surface, so that the temperature in the seat can be prevented from rising abnormally. Further, the ventilation opening is closed by bringing the reflecting member close to the seat forming member, and the ventilation opening is opened by separating the reflecting member from the seat forming member. Therefore, the ventilation opening is provided in the reflecting member. There is no need and the formation of a reflective surface is facilitated.

  In one embodiment, the seat forming member is a reclining adjustable backrest. In this case, even if the seat is in the form of a bed, the temperature of the infant's face can be prevented from rising abnormally. The backrest portion may include a pair of side walls that rise and extend forward from both side edges. Each side wall preferably has a vent opening. The reflecting member includes a pair of side wall reflecting members provided so as to be selectively changeable in positions close to the back surfaces of the pair of side walls and positions away from the back surfaces of the pair of side walls.

As shown in FIG. 1, the reflecting member 4 has a first position located close to the back surface of the backrest portion 2 and a second position located away from the back surface of the backrest portion 2 as shown in FIG. 2. The position can be selectively changed.

  In the reflecting member 4, the outer surface that does not face the backrest 2 forms a reflective surface. The reflective surface is formed, for example, by forming the reflective member 4 itself with an aluminum plate. As another example, a reflective metal such as aluminum may be vapor-deposited or an aluminum foil may be adhered to the surface of the plate material forming the reflecting member 4.

  The holding means 5 holds the reflecting member 4 so that the position of the reflecting member 4 can be changed, and connects the backrest portion 2 and the reflecting member 4 so as to be able to contact and separate (approach and separate). As such a holding means 5, for example, a link member whose both ends are rotatably connected, a flexible belt member, or the like can be used.

  The stopper 6 holds the reflecting member 4 in close contact with the back surface of the backrest portion 2. For example, the displaceable clip attached to the backrest portion 2, the backrest portion 2 and the reflecting member 4 can be removed. A connecting tool or the like to be connected can be used.
