Description

  The present invention relates to a chair for an infant to sit on, and more particularly to an infant chair suitable for an infant whose neck is seated and can be sat and hi-hi.

  Infants who are able to sit and crawl with their necks moving actively should be careful not to go to dangerous places such as near stairs or stoves.

  However, because of housekeeping and other work, parents cannot always monitor. When it is unavoidable to move away from the child, it will be moved in advance to a place where danger can be avoided or other people will see it, but it may not be able to do enough work because of concern about the child There are many.

An example of an infant chair is disclosed in Patent Document 1 below.
This chair has a seat, a backrest, two side supports, a front support and two grooves between the front support and the side support that allow the infant's legs to protrude outwardly from the seat. In addition to providing a certain degree of flexibility to contact, the structure is designed to have sufficient structural stability to support the infant. That is, it is made of a soft material in a form suitable for sitting an infant for the purpose of allowing the infant to sit safely.

  However, this chair has a seat, a backrest, two side supports, a front support, and two grooves that allow the infant's legs to protrude outwardly from the seat between the front support and the side support. Although it has a low profile, it has the advantage of being compact, etc., but the baby can push the side support and the foot can press the grounding surface by flipping the hand or foot. In some cases, the infant got off the chair by his own power.

  For this reason, parents cannot concentrate on errands.

Japanese translation of PCT publication No. 2002-542856

  Therefore, the main object of the present invention is to make it possible to concentrate on errands even when the eyes of the infant are taken away from the child so that the sitting infant does not get off without permission.

  For this purpose, the infant has a concave concave seat portion on which a portion centered on the buttocks of the infant is placed, and a support portion that is connected to the concave seat portion and supports the concave seat portion at the outer peripheral portion of the concave seat portion. In the chair, the concave seat portion and the support portion are formed of a flexible material, and the concave seat portion is deformed under the concave seat portion by the load of the baby riding on the concave seat portion. The baby chair is provided with a deformable space for displacing the inner wall surface of the concave seat portion inward.

  That is, when the baby is seated on the concave seat, the concave seat is deformed due to its flexibility and the presence of the deformation-accepting space, or changes in curvature. Since the concave seat portion has flexibility, the inner wall surface of the concave seat portion can be displaced inward by the above deformation. That is, the inner wall surface of the concave seat is deformed so as to wrap the infant. For this reason, as long as the baby is sitting, the baby cannot get off the chair by his own power.

  While forming two notches for taking out the infant's legs from the concave seat on the front side portion of the concave seat, and standing between the notches, an abdominal facing portion that faces the baby's abdomen, When the inner wall surface of the concave seat portion is displaced due to the deformation of the concave seat portion, the abdominal facing portion which is a part of the inner wall surface is also displaced and tilted toward the infant side, so this abdominal facing portion is an obstacle for the infant. In other words, the action of the baby trying to stand up can be suppressed by the abdomen facing portion. In addition, it can also comprise so that the displacement of the said inner wall surface may occur only in an antinode part.

  Further, the support portion may be formed by folding downward from the upper end edge of the concave seat portion, and a ground contact surface may be formed at the lower end of the support portion so that the baby chair is formed in a mortar shape. Since it can be formed into a smaller shape without legs, it is convenient to carry around without taking up space.

  If the height of the support is set to a height that allows the infant's feet to float above the height of the grounding surface when the infant is seated in a concave seat, the infant will be able to stand up even if the infant flaps the leg. Since it does not become a movement to do, it can make an infant stay more reliably.

  Furthermore, the connecting surface to the abdomen facing part in the concave seat part is deformed when the baby's crotch part gets on, and the abdomen facing part is tilted toward the infant side. When formed on the slope, the displacement of the abdomen facing portion can be made larger than that of other parts, and the operation of the infant can be regulated more efficiently.

  When a backrest that is high enough to support the baby's head is erected on the rear side of the concave seat, when the inner wall surface of the concave seat is displaced by deformation of the concave seat, You can also wrap the back and head other than the part you have done, and regulate the infant's movements.

  As described above, according to the present invention, the concave seat portion and the support portion that are formed of a flexible material, and the deformable space that is formed below the concave seat portion are provided. When sitting, the concave seat wraps around the infant, so the sitting infant cannot escape by himself. For this reason, the baby can be kept in a certain place. In other words, if there is an errand for the guardian and you have to keep an eye on the infant for a while, you can concentrate on the errand for housework by keeping the infant in the infant chair of the present invention. I can do it.

  Moreover, since the support portion that supports the concave seat portion at its outer peripheral portion is also formed of a flexible material, the inner wall surface of the concave seat portion can be reliably displaced.

  Moreover, since the concave seat part and the support part are formed of a flexible material, the concave seat part and the support part are not only soft, but can wrap the baby in a stable manner and are comfortable for the baby.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of an infant chair 11 (hereinafter referred to as a chair), which is a chair suitable for use when a guardian must keep an eye on an infant.

  That is, as shown in FIG. 2, when the baby 12 is seated, the baby 12 has a configuration that cannot be pulled out of the chair 11 by its own power.

  FIG. 3 is a longitudinal sectional view of the chair 11, which is formed by integral molding of resin, and is flexible as a whole, and is flexible so as to bend and displace to other parts when a force is applied to a part. have.

  The overall shape is a mortar-like shape, and a concave concave seat portion 13 on which a part centered on the buttocks 12a (see FIG. 6) of the infant 12 is placed, and a concave seat at the outer peripheral position of the concave seat portion 13. And a support portion 14 that supports the portion 13.

  The concave seat portion 13 has a shape in which a bottom is formed in a spherical shape and an inner wall surface 13a is raised all around. The curvature of the bottom 13b of the concave seat 13 is preferably set larger than the curvature of the buttocks 12a of the infant 12 (see FIG. 6).

  In the concave seat portion 13, two notches 15, 15 are formed on the front side portion for taking out the leg 12 b of the infant 12 sitting on the concave seat portion 13 from the concave seat portion 13 (FIG. 1). (See FIG. 2).

  And between these two notch parts 15 and 15, the abdominal opposing part 16 which stands up from the bottom 13b and opposes the abdominal part of the infant 12 is erected.

  A backrest 17 having a height that supports the head 12 c of the infant 12 is erected on the rear side portion of the concave seat 13.

  The support portion 14 is formed by folding downward from the upper end edge of the concave seat portion 13, and a circular ground surface 18 is formed on the entire periphery of the lower end. The concave seat portion 13 is bent and deformed by the load of the infant 12 riding on the concave seat portion 13 so that the concave seat portion 13 becomes higher than the height of the ground contact surface 18, and the abdominal facing portion 16 and the backrest portion 17 are deformed. A deformable space 19 is provided for displacing the inner wall surface 13a of the concave seat portion 13 including the inward direction (see FIG. 4).

  The size (height) of the deformation-permitting space 19 varies depending on the type of resin and flexibility, but is a size that can sufficiently displace the inner wall surface 13a of the concave seat 13 by the load of the infant 12. If it is.

  Further, the height of the support portion 14 is set to a height at which the foot 12d of the infant 12 floats above the height of the ground contact surface 18 when the infant 12 sits on the concave seat portion 13 as shown in FIG. Is preferred.

  If the chair 11 having such a shape is formed using, for example, a foamed resin such as polyurethane, the chair 11 can have both the softness to the baby and the desired flexibility.

  Molding is performed by a well-known foam injection molding method. In order to give the desired flexibility, it is preferable to use a low foam molding method (SF molding method) in which the surface quality is different from that of the inside. For example, a gas counter pressure method, a USM method, a co-injection method, etc. can be adopted. By using the co-injection method, as shown in FIG. If the non-foamable resin 21 that is not a resin is positioned, better flexibility and surface characteristics can be imparted.

  With respect to the chair 11 configured as described above, the guardian holds the infant 12 and puts it on the concave seat portion 13 of the chair 11, so that the concave seat of the chair 11 is shown in FIG. The part 13 is deformed along the shape of the buttocks 12a of the infant 12 and sinks. Along with this deformation, the inner wall surface 13a of the concave seat portion 13 is bent together with the support portion 14 and displaced inward. That is, the abdomen facing part 16 and the backrest part 17 are displaced inward, and the baby 12 is wrapped softly.

  For this reason, the body of the infant 12 is in a state of being restrained by the chair 11, and the infant 12 cannot get off the chair 11 even if the infant 12 moves actively by its own power.

  Moreover, since the foot 12d of the infant 12 sitting on the concave seat 13 is in a state of floating above the height of the grounding surface 18 of the chair 11, the effect is certain.

  The infant 12 is kept in a stable posture by the backrest 17 having a height that can support the head 12c.

  When the infant 12 is taken down from the chair 11, if the guardian holds the infant 12 by holding it, the load of the infant 12 will not be applied to the concave seat 13, so that the shape of the concave seat 13 returns to the original state. The infant 12 can be lowered.

  Thus, since the infant 12 cannot get off the chair by his / her own power, the guardian can rest assured even if he / she keeps the infant 12 sitting on the chair 11. And parents can focus on what they need.

In correspondence between the configuration of the present invention and the above-described configuration,
The inner wall surface according to claim 1 of the present invention corresponds to the inner wall surface 13a, the abdomen facing portion 16 and the backrest portion 17 of the configuration of the above-mentioned one form,
The configuration of the above-mentioned one form is one form for implementing this invention, This invention is not limited only to the above-mentioned structure.

  For example, the chair 11 may be formed into a chaise longue so that the leg 12d of the infant 12 does not go out.

  Moreover, as shown in FIG. 8, you may comprise so that the belly facing part 16 of the chair 11 may be displaced more largely than another site | part.

  That is, the connecting surface 22 to the abdomen facing part 16 in the recessed seat part 13 is deformed when the crotch part of the infant 12 rides, and the other part of the recessed seat part 13 is tilted to tilt the abdomen facing part 16 toward the infant 12 side. It is formed with a gentle slope with a smaller curvature than the part of. In addition, the continuous surface 22 is set to be thinner than other portions of the wall thickness, and is deformed even with a lighter load.

  If the abdomen facing part 16 is configured to be displaceable larger than other parts in this way, the abdomen facing part 16 becomes an obstacle for the infant 12 and the movement of the body center part is restricted, so that the entire inner wall surface 13a is evenly distributed. Therefore, the movement can be regulated more efficiently than the case where the movement is regulated by displacement.

  Moreover, it can also comprise so that only the antinode part 16 may displace.

  FIG. 9 is a longitudinal sectional view showing a chair 11 suitable for bathing. That is, through holes 23 for drainage are formed in the concave seat portion 13. If such a bath chair 11 is used, the baby can be surely restrained even while the guardian is washing the body, so the baby's safety can be ensured.

  Further, although not shown, the support portion 14 is not formed by folding downward from the upper end edge of the concave seat portion 13, but is formed in a bowl shape, for example, to constitute a chair in combination with other appropriate members. You can also
