Description

  The present invention relates to a stroller having a function of protecting an infant from radiation emitted by radioactive materials scattered on the ground.

  There are various types of strollers. Basically, a baby carriage is equipped with a moving wheel at the bottom and a main body with a hand push frame at the top and a seat (seat) on which an infant can be placed. is there. In many cases, a bag for storing articles is provided below the seat, and a hood for sun protection and rain protection is provided above the seat.

  As this type of baby stroller, a baby stroller provided with an auxiliary cover for sun protection and insect repellent (see Patent Document 1) and a cloth provided with an electromagnetic shielding cloth (see Patent Document 2) have been proposed.

  Recently, radioactive materials were scattered over a wide range due to the nuclear accident caused by a large earthquake and tsunami, and there is concern about the effects of radiation from these radioactive materials on the human body. In particular, infants are said to be easily affected by radiation, and it is necessary to avoid as much as possible that infants are affected by radiation in daily life.

  When going out with an infant, the infant moves in a stroller, but the stroller has a low seat, so the infant in the stroller has a high risk of receiving radiation from radioactive materials scattered on the ground. It is done. However, conventional baby strollers have not been given consideration to radiation from the ground.

  In view of the above circumstances, an object of the present invention is to provide a stroller that can effectively prevent an infant from receiving radiation from the ground.

  In order to solve the above problems, the present invention employs the following configuration. In other words, the stroller according to the present invention described in claim 1 is characterized in that a protective seat for blocking radiation is attached to a seat on which an infant is placed or in the vicinity thereof.

  According to a second aspect of the present invention, a stroller according to claim 2 is provided with an insole of a protective sheet for blocking radiation in a bag provided under the seat of the stroller. As described in claim 3, it is preferable that the protective sheet includes an insole of the protective sheet formed of a plurality of sheet materials, and the plurality of sheet materials are connected to be stretchable.

  The stroller according to claim 4 is provided with protective seats attached to the back and waist of the seat. In this case, it is preferable that a pocket is formed in the seat and a protective sheet is inserted and held in the pocket.

  Furthermore, the baby stroller according to claim 6 is such that a sunshade is suspended from a front end portion of a hood placed on the upper side of the seat, and a protective seat is attached to the sunshade. In this case, as described in claim 7, it is preferable that the awning body is formed as a cloth bag and a protective sheet is inserted into the bag.

  In the stroller according to the present invention, since the protective seat is provided at or near the seat, the infant on the seat is unlikely to receive radiation from the ground. If the position of the protective seat is arranged by using the hook under the seat as described in claim 2, it is convenient because no special attachment means is required. In this case, if the protective sheet is telescopic as shown in claim 3, there is an advantage that it can be easily applied to the size of the ridge.

  Further, as described in claim 4, it is preferable to place protective sheets on the back and waist portions of the seat, since most of the infant's body placed on the seat can be effectively protected. In this case, as described in claim 5, if a pocket is provided in the seat and the protective sheet is inserted and held in the pocket, it is convenient to attach and detach the protective sheet, and the pocket is used for heat insulation. Since materials and cold insulation materials can be attached, it is more effective.

  Furthermore, if the sunshade which has a protection sheet is attached using the existing hood as described in Claim 6, the front side of an infant's body can be protected effectively. In this case, as described in claim 7, if the awning body is formed in a bag shape and the protective sheet is put in and held therein, the protective sheet can be easily attached and detached.

It is a perspective view showing embodiment of this invention. It is a perspective view of a bag. It is a perspective view of the protective sheet insole put in a bag. It is a front view of a seat. It is sectional drawing of a seat. It is a perspective view of the seat which attached the sunshade. It is explanatory drawing of an awning.

  Hereinafter, preferred embodiments of the present invention will be specifically described. FIG. 1 is a perspective view of a stroller according to the present invention. This stroller 1 includes a pair of left and right front leg frames 3 that support a front wheel 2, a pair of left and right rear leg frames 5 that support a rear wheel 4, and a hand frame 7. A seat 10 is attached to an upper and lower middle portion of the main body 8 provided with the above.

  The seat 10 includes a back part 11 and a waist part 12, and the waist part 12 is provided with a crotch support string 13 that rises from the waist part. A buckle 14 is attached to the upper end portion of the crotch support string 13, and a waist support string 15 extending to the left and right is attached to the buckle 14. Although not shown in the drawings, there is a case where a shoulder strap for restraining the infant's shoulder is attached to the buckle 14.

  Armrests 17 are provided on both sides of the seat 10, and a front protective frame 18 for connecting the armrests is provided at the tip thereof. On the lower side of the seat 10, there is provided a bag 20 for storing small items such as drinks and towels as required. In addition, a connecting frame 22 that connects the left and right front leg frames 3 and a connecting frame 23 that connects the left and right rear leg frames 5 are provided, and a footrest 24 is provided in the middle of the front connecting frame 22.

  Further, a hood 30 is provided above the seat 10 so as to cover the seat 10. The hood 30 is attached to a rear frame 31 whose rear portion is fixed to the hand frame 7, and a front portion is attached to a rotary front frame 32. The pivotable front frame 32 is supported by the base 33 and can be extended from the folded state overlapping the rear frame 31 by pulling out the hood 30 so as to cover the upper part of the seat.

  The stroller 1 is provided with a protective sheet S that blocks a large amount of radiation from the ground from reaching the seat 10.

  The protective sheet S is a plate-like or cloth-like sheet that can effectively block radiation, and has been conventionally used to prevent radiation exposure, such as high-lead glass, lead-containing resin (for example, acrylic) plates, A lead-containing cloth or the like can be used. If the amount of lead contained is large, the weight will be large, and if it is small, the radiation shielding effect will be reduced. Therefore, an appropriate one may be selected according to the use, but in the present invention, a material of about 0.3 mmPb is preferred.

  2 and 3 show one example, and an insole 21 of the protective sheet S is laid on the bottom of the bag 20 attached to the lower side of the seat 10. The size of the ridge 20 is, for example, about 300 mm in width and about 500 mm in length. As shown in FIG. 3, the insole 21 of the protective sheet S is formed by arranging a plurality (two in the illustrated example) of sheet materials S1 and S2 so as to overlap each other at the intermediate portion. By adjusting, the overall length can be adjusted. The sheet material S1 is fixed to the flange 20 by fixing means (not shown) such as hooks and pins. The width may be adjusted with the same structure.

  When the protective sheet S is attached using the underarm 20 in this way, radiation from the ground can be effectively blocked. Since the protective sheet is made of a lead-containing material, the weight is relatively large. However, if the structure is as shown in the drawing, it is convenient because the protective sheet S can be easily removed when not needed.

  Next, FIG. 4 shows an example in which the protective sheet S is attached to the seat 10. As shown in FIG. 5, when the seat 10 includes a high-strength base 10a made of resin and a cushion 10b placed on the base, the protective sheet S may be attached to the cushion 10b. You may arrange | position between 10a, Furthermore, you may attach to the back side of the base 10a. Since the seat 10 includes a back portion and a waist portion, it is preferable that the protective sheet S is also disposed on the back portion and the waist portion.

  When the protective sheet S is attached to the seat, for example, if a pocket P is provided at an appropriate position of the cushion 10b (or the base 10a) and the protective sheet is inserted into the pocket, the protective sheet can be easily attached. . This pocket P is more effective if it can hold cold insulation material or ice on a hot day, and can keep a heat insulation material on a cold day.

  FIG. 6 shows an example in which a sunshade 40 that covers the front of the seat is provided. As shown in FIG. 7, the awning 40 has a cloth bag shape and is provided with an opening 41 at the top. The opening 41 can be closed by a zipper-type opening / closing tool 42. A protective sheet S can be inserted in the bag-shaped awning 40.

  The awning 40 is suspended by a rod 45 that is passed to the front frame 32 of the hood 30. The rod 45 is supported by a support 46 provided on the front frame 32 and can be attached and detached together with the awning 40 as necessary. The protective sheet S can be removed and only the bag-shaped awning can be used. The size of the awning 40 may be an appropriate size according to the use conditions and the like, but it is usually sufficient to have a width of about 200 mm and a height of about 200 mm.

  The stroller 1 provided with the awning 40 can effectively shield radiation from the front with a protective sheet provided on the awning. Also, when there is no concern about radiation, it can be used as a simple detachable awning.

  As is clear from the above description, the stroller according to the present invention is provided with the protective sheet S that blocks radiation near the seat on which the infant is placed, so that the infant is exposed to radiation even in a place where radioactive materials are scattered. Can be effectively prevented. In the illustrated example, the case where the hand frame is provided on the back side of the main body has been described as an example, but the hand frame is provided on the front side of the seat and can be pushed while looking at the infant's face, or a folding stroller. The same can be applied to.

  Further, in the above description, three different embodiments have been described. However, these may be selectively combined, and the respective embodiments may be employed separately depending on the situation.
