Description

Detailed Description of the Invention

この発明は、ビニールやポリウレタン等可塑性のシートで構成され空気で膨らませる子供用のいすに関するものである。 The present invention relates to a children's chair made of a plastic sheet such as vinyl or polyurethane and inflated with air.

従来、空気で膨らませるいすは存在したが空気入れを用意するという不便さがあった。また、空気室が分かれ、それぞれの空気注入が煩雑であった。さらに口からの空気注入には、かなりの力と時間を費やした。 Conventionally, there have been chairs that are inflated with air, but there has been the inconvenience of preparing an inflator. Moreover, the air chamber was divided and each air injection was complicated. Furthermore, considerable power and time were spent in injecting air from the mouth.

Problems to be solved by the invention

本発明は、その欠点を除いて、軽量で移動に便利であること、さらに使用する際、空気注入方法を簡単に尚且つ衛生的にできるよう開発しようとするものである。 The present invention, except for its drawbacks, seeks to be light and convenient to move, and to develop a simple and sanitary air injection method when used.

Means for solving the problem

いま、解決手段を図を追いながら説明すれば
（イ）シートを中空にし、いす状に形成し、
（ロ）座部の前部に幼児の前ずれ防止用に２の突起を一体に設ける。
（ハ）その上部に空気取入孔を有する１の空気弁を設ける。
（二）その突起内部下部にも逆止弁を有する空気弁を設ける。
以上のように構成しシートで出来た伸縮性の突起２を手で上下させることで、空気ポンプの役割を持たせる。突起を含め全体を可塑性のあるシートで１気室に構成すれば、このポンプを手で上下させるだけで空気が充填され子供用のいすが出来、さらに突起２は幼児が座った際の前ずれの防止にも役立ち安全である。Now, if you explain the solution by following the diagram, (a) make the sheet hollow, form a chair,
(B) Two protrusions are integrally provided at the front part of the seat part to prevent the infant from moving forward.
(C) One air valve having an air intake hole is provided at the top thereof.
(2) An air valve having a check valve is also provided in the lower part of the protrusion.
The role of an air pump is given by raising and lowering the elastic protrusion 2 made of a sheet constructed as described above by hand. If the entire structure including the protrusions is made up of one plastic chamber with a plastic sheet, this pump can be filled with air by simply moving the pump up and down by hand to make a child's chair. It is also safe and helps to prevent.

Form of the actual state of the invention

本発明は、以上のような構造で、空気排出時は図３の空気弁の係止部１４を押し下げる。なお、空気栓７を図２のようにさらに別に設け空気の排出に使用することが望ましい。空気栓７は一般的な空気ビニール玩具や浮き輪等に使用される栓である。空気注入時は空気栓７の蓋をしてから空気弁１の蓋１０をあけ、２を上下に動かすことで、空気が注入され、本器を簡便に膨らませることができる。 The present invention has the above structure, and pushes down the locking portion 14 of the air valve in FIG. In addition, it is desirable to further provide an air plug 7 as shown in FIG. The air plug 7 is a plug used for a general air vinyl toy, a floating ring or the like. At the time of air injection, the lid of the air valve 7 is closed and then the lid 10 of the air valve 1 is opened. By moving 2 up and down, air is injected and the device can be inflated easily.

空気ポンプの構成は、弁を上下２箇所以上に有すれば良く、本体突起２と併せて全体を１気室の構造とすることで本体の形成が迅速かつ容易となる。図３の突起上端の空気弁を説明すると、１３の弁上部を突起２の先端の上部表面に穴を開けて溶着させる。９の空気取入孔は中央に貫通孔を一つ有し、その回りにも環状に幾つかの貫通孔を有する。中央の貫通孔に図５の可動弁を係止部１４によって吊るした構造となっている。図５の可動弁１１は柔らかいシート状でゴムや樹脂などで構成される。上部から取り込まれた空気は可動弁１１を押し下げ内部に空気を流入させる。ポンプ内底下部に取り付けた図４の空気弁も同様である。一旦、取り込まれた空気は内部から図４の可動弁１１‘を押し上げ、空気弁下部表面の１２に密着するので空気洩れは起こらない。なお、図３と図４は基本的に同一構造で、図３は蓋１０を一体に有するに過ぎない。１２の空気弁下部は上部に湾曲しておりゴムやシートを打ち抜きした可動弁１１との密着を防ぎ表面積を広くしている。 The structure of the air pump is sufficient if the valve is provided at two or more locations in the upper and lower sides, and the main body can be formed quickly and easily by making the whole structure into one air chamber together with the main body protrusion 2. The air valve at the upper end of the protrusion in FIG. 3 will be described. The upper part of the valve 13 is formed by welding a hole in the upper surface of the tip of the protrusion 2. The air intake hole 9 has one through hole in the center, and has several through holes around it. The movable valve shown in FIG. 5 is suspended by a locking portion 14 in the central through hole. The movable valve 11 shown in FIG. 5 is a soft sheet and is made of rubber or resin. The air taken in from the upper side pushes down the movable valve 11 and causes air to flow into the inside. The same applies to the air valve of FIG. 4 attached to the bottom of the inner bottom of the pump. The once taken-in air pushes up the movable valve 11 ′ in FIG. 4 from the inside and comes into close contact with the air valve lower surface 12, so that air leakage does not occur. 3 and 4 basically have the same structure, and FIG. 3 merely includes the lid 10 integrally. The lower part of the air valve 12 is curved upward so as to prevent contact with the movable valve 11 in which rubber or a sheet is punched out to increase the surface area.

空気ポンプの構成は空気弁としては、上下一対であれば良い。また、空気弁の構造には前記以外にも様々な形式が考えられる。上部に敷設する弁として図６も考えられる。この空気弁は本体１６の下部に可動式の弁１７を有し、蓋１５を有する。また、図８は別の空気ポンプの内部構造を表したもので上部に空気弁１を有し、下部に発泡弾性体１９とその係止部１８のシートで構成し側部にシートを筒状にした２２の弁を有する。１８より下の部分は空気室内部に包合されて露出していない部分である。筒状のシート２２は空気流入時には筒状に広がるが、その後は気室の内部空気圧によって潰され空気の排出は止まる。空気ポンプの構造はスポンジを介さなくてもよく、図７の如く下部にチューブ状のシートを空気弁とし係止部１８の下に直接つなげた内部構造でも構わない。図７ではチューブの貼り付きを防止するために下部にスリットを設けたが、穴を片側に開けても構わない。また、チューブ内表面に砂状模様にシボを有しておくことも貼り付けの防止に有効である。 The configuration of the air pump may be a pair of upper and lower air valves. In addition to the above, various types of air valve structures are possible. FIG. 6 is also conceivable as a valve laid on the top. This air valve has a movable valve 17 at the bottom of the main body 16 and a lid 15. FIG. 8 shows the internal structure of another air pump, which has the air valve 1 in the upper part, is composed of a foamed elastic body 19 and a sheet of its locking part 18 in the lower part, and the sheet is cylindrical in the side part. There are 22 valves. The portion below 18 is a portion that is enclosed in the air chamber and is not exposed. The cylindrical sheet 22 spreads in a cylindrical shape when air flows in, but thereafter, the cylindrical sheet 22 is crushed by the internal air pressure of the air chamber and the discharge of air stops. The structure of the air pump does not have to be via a sponge, and may be an internal structure in which a tubular sheet is used as an air valve at the lower part and directly connected to the bottom of the locking portion 18 as shown in FIG. In FIG. 7, a slit is provided in the lower portion to prevent the tube from sticking, but a hole may be formed on one side. In addition, it is also effective for preventing sticking to have a sand-like pattern on the inner surface of the tube.

以上のように本発明は空気で膨らんでいるので使用感は柔らかく、しかも折り畳めば軽く場所も取らずに移動にも簡便である。また、空気入れが本体と一体になっているので、使用時も楽でありいつでも使うことが出来る。 As described above, since the present invention is inflated with air, the feeling of use is soft, and when folded, it is light and easy to move without taking up a place. In addition, since the inflator is integrated with the main body, it is easy to use and can be used at any time.

The invention's effect

空気ポンプが本体と一体に形成されているので、空気入れを使用することなく、また、口から空気を注入することなく、簡単に且つ衛生的に場所を選ばず子供用のいすを膨らませることが出来る、使用後は空気を抜けば後片付けも容易であり、使用感もソフトである。 Since the air pump is formed integrally with the main body, children's chairs can be inflated easily and hygienically anywhere without using an air pump or injecting air from the mouth. However, after use, if the air is removed, it is easy to clean up and the feeling of use is soft.
