Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a pneumatic chair for infants.

[0002]

[Prior art]

 Conventionally, this type of pneumatic chair has only a backrest with an armrest around the upper surface of a seat, that is, an expanding and contracting enormous portion 12 for preventing front displacement provided in the present invention. Had no format. For this reason, there was a problem that the infant sitting on the floor was likely to move forward and fall down and fall asleep while moving his limbs.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a new pneumatic chair in which the above-mentioned problems in the prior art are solved by providing an inflatable front displacement preventing enlarged portion 12 at the center of the front edge of the seat. It is intended for.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a pneumatic chair according to the present invention is provided at the center of the front edge of the seat in the expandable and contractable pneumatic chair having a backrest with armrests around the upper surface of the seat. And a swellable portion 12 for preventing front displacement that can be expanded and contracted and placed between the crotches of the user.

[0005]

【Example】

 The embodiment shown in the figure is a thermoplastic soft synthetic resin lower sheet whose inner and outer peripheral edges are cut into a U-shape in the same manner as the thermoplastic soft synthetic resin upper sheet 1 whose inner and outer peripheral edges are cut into a shape exhibiting a U character. 2 are welded together to form a backrest member 3 with an armrest, and a heat transfer member having a U-shaped outer peripheral edge and a linear front edge on the lower surface of the backrest member 3 with the armrest. A chair body 5 is constructed by disposing a bottom sheet 4 made of a plastic and soft synthetic resin and attaching an outer peripheral edge of the bottom sheet 4 to the lower surface of the backrest member 3 with an armrest by welding, and separately from the backrest member 3 with an armrest. The front side sheet 6 and the back side sheet 7 made of a thermoplastic soft synthetic resin having substantially the same size as the inner peripheral edge are overlapped, and the entire outer peripheral edge excluding the central portion on the front side and a number of horizontal parallel lines are mutually welded. This constitutes the seat member 8, and this seat The material 8 is placed on the bottom sheet 4 and its rear edge is fixed to the bottom sheet 4 by welding. Further, a large hole 9 is opened at the upper surface of the backrest portion of the backrest member 3 with armrests. A pillow portion 11 is provided by disposing a hat-shaped body 10 made of a thermoplastic soft synthetic resin sheet on the upper side of the hole 9 and fixing the skirt edge thereof to the cut edge of the hole 9 by welding. The front non-welded portion of the front edge of the front seat 6 and the rear edge of the back seat 7 of the seat member 8 is extended and the peripheral edges thereof are welded to each other to provide an enlarged portion 12 for preventing front displacement. The backrest member 3 and the seat member 8 are configured to be expanded and contracted by the air supply and exhaust plugs 13 and 14, and a thin cushion (not shown) is provided between the seat member 8 and the bottom sheet 4 by a user. ) Etc. can be stored and used arbitrarily.

[0006]

[Effect of the invention]

 The pneumatic chair according to the present invention includes an inflatable chair with a backrest with armrests around the upper surface of the seat, and a center of the front edge of the seat at the center of the front edge of the seat. When the infant is to be seated on the front displacement preventing swelling portion 12, the front displacement preventing swelling portion 12 is preliminarily placed in an inflated state. Is used in such a way that the infant is seated in such a way that it can be sandwiched between the infants' crotches, and there is no advantage in how to use it. The function is to prevent the displacement of the infant from being caught in the crotch of the infant by the front displacement prevention enormous portion 12 and reliably prevent the displacement of the infant. It moves to the front and falls down and falls asleep In addition, the present invention has a remarkable effect of completely achieving the intended purpose. Further, in the present invention, the front displacement preventing enormous portion 12 is provided with a seat member as in the above embodiment. The structure is simple and easy to make even if the leading edge of the above is extended.

The present invention can be implemented in various ways without departing from the spirit of the present invention as follows, and the present invention extends to those implemented as well.・ Increase the size for adult care recipients.・ Omit the bottom sheet and replace it with a seat member. -An air supply / exhaust plug is attached to the front displacement prevention expanding portion 12 so that it can be arbitrarily expanded and contracted independently of the seat member. In the above embodiment, the front displacement preventing expanding portion 12 has a dovetail shape in order to be easily hooked on the thigh portion so as not to come off easily, but may have another shape.
