Abstract
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, liquids such as water and gases such as air that have accumulated have been pressurized by a pump device or the like using energy such as electricity or fuel and moved by a hose or the like. In addition, most of the pump devices using human power are limited to either suction or discharge. As a pump device using human power, a hand-pushed well pump, a hand-pushed bicycle pump, and the like are generally known. As for the foot-operated type, a bicycle pump using the repulsive force of a spring and a bellows type inflator using the restoring force of resin are also widely used. Further, mainly overseas, an irrigation pump is known in which tread plates provided outside the two piston pumps are interlocked with each other by a wire. In the prior invention, a tread plate is provided on two piston pumps in parallel so that they can be stepped on alternately with both feet, and both feet are placed on a water pump that is interlocked by a string-like member or two piston pumps in parallel. A tread plate that is stepped on alternately is provided, and the tread plates are pivotally attached to each other by one arm having a pivot point in the center, and a water pump that is interlocked by the pivot of the arm, and one plate with one foot. There is an air pump that moves like a seesaw with a shaft provided at the lower center of the plate as a pivot point and alternately interlocks two piston pumps at the lower part of the plate.
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) 特開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 are the following problems.
(B) Since energy such as electricity and fuel is indispensable for electric and engine pump devices, power outages occur outdoors in areas where electricity does not reach, areas where it is difficult to supply fuel, etc., especially in the event of an emergency or disaster. It could not be used when the fuel was exhausted.
(B) Since the power pump device is relatively expensive, it was difficult to purchase it in ordinary households.
(C) The financial burden of the powered pump device was indispensable because electricity and fuel costs were incurred.
(D) Powered pump devices inevitably generate loads on nature and the environment.
(E) With the commonly used hand-push type and foot-operated type pumps, one pump is sucked in and discharged, resulting in poor work efficiency.
(F) The hand-held pump consumes a lot of physical strength when used, so the user is easily tired.
(G) The hand-push pump was harder to apply force than the foot-operated pump, and it was difficult to generate higher pressure.
(H) In the hand-push type pump, the pump is fixed with the feet and pushed with both hands, so the user cannot perform any work other than operating the pump, and has no choice but to rely on others to operate the hose and the like.
(I) In the microfilm foot pumps of JP-A-2009-287535 and Japanese Patent Application No. 52-067987 (Jitsukai Sho 53-161303), the rotational movement of the pivotal footboard is pivotally attached to the footboard. It has difficulty in functioning as a pump because it hinders the vertical movement of the piston.
(N) The foot pump of the registered utility model No. 36810 is used as a pump because the joint position of the string-shaped member and the piston for interlocking and the passing position of the string-shaped member with respect to the pulley give a load that hinders the vertical movement of the piston. There is a problem with the function.
(L) The foot pump of Japanese Patent Application Laid-Open No. 2014-267152 has a difficulty in functioning as a pump because the support portion of the foot plate is only one point of the piston and it is easy to cause back and forth blurring.
(Wo) Irrigation foot pumps, which are widely used overseas, have a slanted foot plate on the outside of the cylinder pump, so it is necessary to hold onto the handle attached to maintain posture, and the hose It is difficult to carry because it cannot be operated and the pump device becomes large and heavy.
The present invention has been made to solve the above problems.

Taking the movement of water as an example, in the past, water was used by using the pressure obtained by using energy such as electricity and oil, such as water supply, engines, and motorized pumps such as motors. The main method was to move it.
In addition, when using human power such as body weight, it was limited to the work of either water absorption or water discharge.
According to the present invention, even in a place where there is no water supply or when it is difficult to secure a power source, etc., the stagnant water such as a bucket, a bathtub, a river or a pond can be discharged from the tap with the energy that anyone can exert the maximum power. It can be used like "water".
Further, according to the present invention, the same effect can be expected not only in water but also in liquids such as petroleum and gases such as air.
In addition, since the pump can be stepped on more stably than the conventional hand-push type pump or the foot-operated pump with a handle that holds the posture, both hands are free and the hose for suction or discharge can be operated while stepping on.
In addition, for home use, the remaining hot water in the bathtub can be put into a washing machine, and rainwater collected outdoors can be effectively used for cleaning, car washing, gardening, sprinkling water, etc., so that an effect of saving water can be expected.
In addition, it is not necessary to pull the hose to the place where water is to be used as in the past, and effects such as ensuring the safety of the workplace and improving work efficiency can be expected.
In addition, since the body weight is used as energy, the water pressure rises more when used by a heavier person, so a diet effect can be expected for a person who is concerned about the body weight.
In addition, since it does not require energy such as electricity or fuel, in the event of an emergency or disaster, it can be used for drainage work, discharge work of poisonous gas, flammable gas by electricity, and air supply to people requiring rescue. Is also valid.
In addition, compared to manual pumps, it is possible to work efficiently with the least fatigue when working for a long time, so it is possible to reduce the risk of life of the person requiring rescue and to reduce the fatigue of the victim until disaster recovery. Can be reduced.
In addition, since water can be used efficiently, it can be expected to be effective in saving limited water and managing hygiene even in cleaning and cleaning temporary toilets for disasters.
In addition, since water can be discharged as vigorously as tap water, it is safer to extinguish fires such as barbecues and bonfires outdoors and to extinguish fires caused by them, rather than putting water in a bucket or the like close to the fire. And you can effectively extinguish the fire.
Also, for water fetching work outdoors from dangerous places such as valley bottoms and cliffs, on bridges, breakwaters, shores, etc., you can safely and effectively fetch water just by lowering the hose to the water source. It can be done and can be expected to be effective as a simple well.
Moreover, since energy such as electricity and fuel is not used, it is economical because there is no electricity or fuel cost.
In addition, since energy such as electricity and fuel is not used, the load on the natural environment is eliminated.
In addition, since it does not require a prime mover such as a motor or engine, the structure can be simplified and the weight can be reduced, which makes it easy to carry and can be manufactured and sold at a lower cost than a prime mover pump.
In addition, it can be manufactured and sold at low cost, and its structure is simple and easy to understand and apply, so great demand can be expected in developing countries and regions, and heavy labor, conflicts, and non-compliance to secure water. It can also be expected to be effective in resolving infectious diseases in a hygienic environment.
In addition, because the structure is simple, the risk of failure is low and maintenance is easy, so it can be used for a long time even in areas where transportation is difficult to access, so it contributes to voluntary activities by local residents, so from the outside It can also be expected to reduce the assistance of.
Also, in various industries such as agriculture, forestry, fisheries, manufacturing, and construction and civil engineering, the manufacturing cost is low, the economic efficiency of using energy only by weight, and the reduction of the load on the natural environment.
