Description

本発明は、足踏みポンプに関するものである。 The present invention relates to a foot pump.

従来、滞留している水等の液体、空気等の気体は、電気や燃料等のエネルギーを用いたポンプ装置等で加圧し、ホース等で移動させていた。また、人力を利用したポンプ装置は、吸入か排出どちらか一方に限ってのものが主であった。人力を利用したポンプ装置は、一般には手押し式井戸ポンプ、手押し式の自転車の空気入れ等が知られている。また、足踏み式に関しては、バネの反発力を利用した自転車用空気入れや、樹脂の復元力を利用したジャバラ式の空気入れ等も一般に普及している。また、主に海外に於いて、２つのピストンポンプの外部に設けた踏み板同士をワイヤで連動させる灌漑用ポンプが知られている。なお、先願発明には、並列させた２つのピストンポンプの上に両足で交互に踏むに踏み板を設け、ひも状部材で連動させる水用ポンプや、並列させた２つのピストンポンプの上に両足で交互に踏む踏み板を設け、踏み板同士を中心部に枢動点を設けた１本のアームで軸着させ、アームの枢動により連動する水用ポンプ、また、片足で１枚の板を、板の中心下部に設けた軸を枢動点としてシーソーのように動かし、板の下部にある２つのピストンポンプを交互に連動させる空気ポンプなどがある。 Conventionally, stagnant liquids such as water and gases such as air have been pressurized with a pump device using energy such as electricity or fuel, and then moved with a hose or the like. Furthermore, pump devices using human power were mainly limited to either suction or discharge. Pump devices that utilize human power are generally known as hand-held well pumps, hand-held bicycle air pumps, and the like. Regarding foot-operated air pumps, bicycle air pumps that utilize the repulsive force of springs and bellows-type air pumps that utilize the restoring force of resin are also popular. Furthermore, irrigation pumps are known, mainly overseas, in which two piston pumps are connected with footboards provided on the outside using wires. In addition, the prior invention includes a water pump in which a step plate is provided on two piston pumps arranged in parallel and is stepped on alternately with both feet, and the footboards are linked with a string-like member, and a footboard is provided on two piston pumps arranged in parallel, and a footboard is provided on the top of the two piston pumps arranged in parallel. The system is equipped with treads that are stepped on alternately, and the treads are pivoted to each other by a single arm with a pivot point in the center.The water pump is linked by the pivoting of the arm. There is an air pump that moves like a seesaw using a shaft provided at the bottom center of the board as a pivot point, and alternately operates two piston pumps located at the bottom of the board.

特開２００９－２８７５３５号公報JP2009-287535A 特願２０１４―２６７１５２号公報Patent Application No. 2014-267152 登録実用新案３６８１０号明細書Registered utility model specification No. 36810 実願昭５２－０６７９８７（実開昭５３－１６１３０３号）のマイクロフィルムMicrofilm of Utility Application No. 52-067987 (Utility Application No. 53-161303)

そのため、次のような問題点があった。 (イ) 電気式やエンジン式のポンプ装置では、電気や燃料等のエネルギーが不可欠であるため、電気の届かない屋外、燃料等の供給が困難な地域、特に、緊急時や災害時の停電や燃料切れに於いては使用できなかった。（ロ）動力式ポンプ装置は、比較的高価であるため一般家庭等では購入が困難であった。(ハ) 動力式ポンプ装置は、電気代や燃料代が発生するため経済的負担が不可欠であった。 (ニ) 動力式ポンプ装置は、自然や環境への負荷発生が不可避であった。 (ホ) 一般に普及している手押し式や足踏み式のポンプでは１つのポンプを吸入、排出させるため、作業効率が悪かった。(へ) 手押し式ポンプでは、使用時に多くの体力を消費するので、使用者が疲れやすかった。（ト）手押し式ポンプでは、足踏み式ポンプに比べて力が入れづらく、より高い圧力を発生させにくかった。 (チ) 手押し式ポンプは、ポンプを足で固定し、両手で押すので、使用者はポンプを操作する以外の作業は出来ず、ホース等の操作を他者に依存するしかなかった。 (リ) 特開２００９－２８７５３５公報及び実願昭５２－０６７９８７（実開昭５３－１６１３０３号）のマイクロフィルムの足踏みポンプは枢動する足踏み板部の回転運動が足踏み板部に軸着されたピストン部の垂直運動を阻害するためポンプとしての機能に難がある。 (ヌ) 登録実用新案３６８１０号明細書の足踏みポンプは連動のためのひも状部材とピストンの接合位置およびひも状部材の滑車に対する通過位置がピストンの垂直運動を阻害する負荷を与えるためポンプとしての機能に難がある。 (ル) 特願２０１４－２６７１５２号公報の足踏みポンプは足踏み板の支持部がピストンの１点のみなので前後にブレを生じさせやすいのでポンプとしての機能に難がある。（ヲ）主に海外で普及している灌漑用足踏みポンプは、シリンダーポンプの外部に傾斜した足踏み板が付いているので、体勢を保持するために装着されたハンドルにつかまる必要があり、ホースの操作ができず、また、ポンプ装置が大型化するため、重量も増すので持ち運びが困難である。本発明は、以上の問題点を解決するためになされたものである。 Therefore, there were the following problems. (b) Electric and engine-type pump devices require energy such as electricity and fuel, so they can be used outdoors without electricity or in areas where it is difficult to supply fuel, etc., especially during power outages or disasters during emergencies or disasters. It could not be used when it ran out of fuel. (b) Power pump devices are relatively expensive, so it has been difficult for ordinary households to purchase them. (c) Power pump equipment was an essential economic burden due to electricity and fuel costs. (d) Power pump devices inevitably place a burden on nature and the environment. (E) The generally popular hand-type and foot-type pumps have poor work efficiency because they use one pump for suction and discharge. (f) Hand pumps consume a lot of physical strength when they are used, so users tend to get tired easily. (g) With a hand pump, it was difficult to apply force and it was difficult to generate higher pressure than with a foot pump. (h) With hand pumps, the pump is fixed with the foot and pushed with both hands, so the user cannot do anything other than operate the pump, and has no choice but to rely on others to operate the hoses, etc. (li) In the microfilm foot pump disclosed in Japanese Unexamined Patent Publication No. 2009-287535 and Utility Application No. 52-067987 (Utility Model Application No. 53-161303), the rotational movement of the pivoting foot plate is pivoted to the foot plate. This hinders the vertical movement of the piston, making it difficult to function as a pump. (J) The foot pump of Registered Utility Model No. 36810 cannot be used as a pump because the joining position of the string-like member and the piston for interlocking and the passing position of the string-like member with respect to the pulley create a load that inhibits the vertical movement of the piston. There is a problem with the function. (L) The foot pump disclosed in Japanese Patent Application No. 2014-267152 has a problem in functioning as a pump because the support part of the foot plate is only at one point on the piston, so it tends to shake back and forth. (w) Irrigation foot pumps, which are mainly popular overseas, have an inclined foot plate attached to the outside of the cylinder pump, so you have to hold on to the attached handle to maintain your position. In addition, the pump device is large and heavy, making it difficult to carry. The present invention has been made to solve the above problems.

主に水の移動を例に挙げれば、従来は、インフラとしての水道やエンジン、モーター等の原動機付きポンプ等、電気や石油等のエネルギーを使用することによって得られた圧力を利用し、水を移動させる方法が主であった。また、体重等の人力を利用する場合は、吸水か出水どちらかの作業のみにかぎられていた。本発明により、水道が無い場所や電源等の確保が困難な場合でも、バケツや浴槽、川や池などの滞留した水を、体重というだれでも最大の力を出せるエネルギーにより「水道の蛇口から出る水」のように利用できる。また、本発明により、水に限らず石油等の液体、空気等の気体に於いても同様の効果が期待できる。また、従来の手押し式ポンプや体勢を保持するハンドルが付いた足踏み式ポンプに比べてポンプを安定して踏めるため、両手が自由になり、踏みながら吸入、あるいは排出用のホースを操作できる。また、家庭用に於いては、浴槽の残り湯を洗濯機に入れたり、屋外に溜めた雨水等を、掃除、洗車、ガーデニング、打ち水等に有効利用できるため、節水の効果も期待できる。また、従来のように水を使用したい場所までホースを引く必要がなく、作業場の安全確保や作業効率の向上等の効果も期待できる。また、体重をエネルギーとして利用しているのでより体重の重い人が使用すればより水圧が上がるので、体重を気にしている人にはダイエット効果も期待できる。また、電気や燃料等のエネルギーを必要としないので、緊急時や災害時においては、排水作業や毒ガス、電気による引火性のある気体等の排出作業、さらには、要救助者に対する空気の供給にも有効である。また、手動式ポンプに比べても長時間の作業に於いては、もっとも疲労の少ない動作で効率よく作業ができるため、要救助者の生命の危険を軽減でき、災害復旧まで被災者の疲労も軽減できる。また、効率よく水を利用できるので、災害用仮設トイレ等の洗浄や清掃に於いても、限られた水の節約と衛生管理にも効果が期待できる。また、水道のように勢いよく水を放出できるため、屋外でのバーベキューやたき火等の消火や、それらを原因とする火災の消火活動も、バケツ等の水を近づけて火にかけるよりも、安全かつ効果的に消火活動ができる。また、屋外に於いて危険な場所、例えば、谷底や崖下、橋の上や防波堤、磯等からの水汲み作業も、水源にホースを下ろすだけで、安全かつ、効果的に水汲み作業ができ、簡易的な井戸としても効果を期待できる。また、電気や燃料等のエネルギーを使用しないため、電気代や燃料代がかからず経済的である。また、電気や燃料等のエネルギーを使用しないため、自然環境への負荷がなくなる。また、モーターやエンジン等の原動機を必要としないため、構造を簡素化でき、軽量化されるため、持ち運びも容易になり、さらには原動機式ポンプに比べ低コストで製造、販売ができる。また、低コストで製造、販売ができ、構造も単純で簡単に理解、応用ができるので、開発途上の国や地域に於いて大きな需要が期待でき、水の確保のための重労働や紛争、不衛生な環境に於ける伝染病の解決にも効果が期待できる。また、構造が単純なため、故障のリスクが低く、メンテナンスも容易なので、交通のアクセスが困難な地域でも長期的な使用ができるため、その地域住民による自発的な活動に貢献するため、外部からの援助の軽減も期待できる。また、農業、林業、水産業、製造業、建築土木業等の諸産業に於いても、製造コストの低さと、体重のみのエネルギー使用という経済性、さらには、自然環境への負荷の軽減性から、多種多様な状況に関しての応用性と発展性が期待できる。 Taking the movement of water as an example, in the past, water was moved using pressure obtained by using energy such as electricity or oil, such as infrastructure such as water supply or motorized pumps such as engines and motors. The main method was to move it. Furthermore, when using human power such as body weight, it was limited to either water absorption or water extraction. With the present invention, even in places where there is no running water or where it is difficult to secure a power source, stagnant water in buckets, bathtubs, rivers, ponds, etc. can be removed by using the energy of body weight, which anyone can use to produce maximum force, by ``getting it out of the tap''. It can be used like water. Further, according to the present invention, similar effects can be expected not only with water but also with liquids such as petroleum and gases such as air. Additionally, compared to conventional hand-pumps or foot-operated pumps that have a handle to maintain your position, you can press the pump more stably, freeing up both hands and allowing you to operate the suction or discharge hose while stepping on the pump. In addition, for home use, water savings can be expected as residual hot water from the bathtub can be put into the washing machine, and rainwater collected outdoors can be effectively used for cleaning, car washing, gardening, sprinkling, etc. Additionally, there is no need to run a hose to where you want to use water, unlike in the past, and you can expect benefits such as ensuring workplace safety and improving work efficiency. Also, since it uses body weight as energy, the water pressure will increase if used by a heavier person, so it can also be expected to have a diet effect for people who are concerned about their weight. In addition, since it does not require energy such as electricity or fuel, it can be used for drainage work, poisonous gas, discharge of flammable gases, etc. using electricity, and even supplying air to people in need of rescue during emergencies and disasters. is also valid. In addition, compared to manual pumps, it is possible to work efficiently with the least tiring action during long hours of work, reducing the risk to the lives of those in need of rescue and reducing the fatigue of victims until recovery from the disaster. It can be reduced. In addition, since water can be used efficiently, it can be expected to be effective in saving limited water and hygiene management when washing and cleaning temporary disaster toilets, etc. In addition, since water can be released forcefully like a tap, extinguishing outdoor barbecues, bonfires, etc., and extinguishing fires caused by such things are safer than using buckets of water close to the fire. and can effectively extinguish fires. In addition, when drawing water from dangerous outdoor locations such as the bottom of a valley, under a cliff, on a bridge, breakwater, or from a rocky shore, you can safely and effectively draw water by simply lowering the hose to the water source. It can be expected to be effective as a simple well. In addition, since no energy such as electricity or fuel is used, it is economical as there are no electricity or fuel costs. Additionally, since no energy such as electricity or fuel is used, there is no burden on the natural environment. In addition, since it does not require a prime mover such as a motor or engine, it has a simpler structure and is lighter in weight, making it easier to carry, and it can be manufactured and sold at a lower cost than a prime mover pump. In addition, because it can be manufactured and sold at low cost, has a simple structure, and is easy to understand and apply, it can be expected to be in high demand in developing countries and regions, and will be used to prevent heavy labor, conflicts, and problems related to securing water. It is also expected to be effective in solving infectious diseases in a sanitary environment. In addition, because the structure is simple, the risk of breakdown is low and maintenance is easy, so it can be used for a long time even in areas with difficult access to transportation. We can also expect a reduction in aid. In addition, in various industries such as agriculture, forestry, fisheries, manufacturing, and construction and civil engineering, it is possible to reduce production costs, use only body weight as energy, and reduce the burden on the natural environment.
