Description of the Related Art A conventional portable foot pump used for filling air in a rubber boat or the like is provided with a bellows between an upper plate and a lower plate, a check valve for suction and discharge on the upper plate, and one foot. Then, the bellows is compressed by pressing the upper plate to send air from the discharge valve, and the bellows compressed by the spring force is returned to suck air. However, there is a problem that the stepping on one foot is difficult for the user to apply weight because the center of gravity of the person does not step on the leg, and the spring force becomes resistance when compressed. Further, there is also a problem that the amount of air supply is small and it takes time to fill the air.

ることになる。 According to the first aspect of the present invention, an upper member having an upper plate on which both feet of a person can be placed substantially symmetrically about a center line extending in the front-rear direction is rotatably supported by a lower member. Therefore, a person can step on the upper member alternately with both feet while riding on the upper plate of the upper member. Thereby, the bendable airtight members attached so as to surround the upper member and the lower member can be alternately expanded and contracted to change the internal volume. On the other hand, the upper member or the lower member is provided with a partitioned space portion.For example, if the upper member is provided with a partitioned space portion, each partitioned space portion of the upper member is a respective airtight member. Each part of the upper member is electrically connected to the enclosed part, and each part of the upper member is provided with a one-way valve for suction and discharge which is electrically connected to the space and the outside, so that each time the airtight member expands and contracts on each side. In addition, the suction valve and the discharge valve can take in fluid from outside and discharge it to the outside.
That is, each time the upper member is alternately depressed with both feet, the fluid is discharged on each side, so that the pump becomes a double-acting pump, and a discharge amount twice as large as that of the conventional one-stepping pump can be obtained. In this case, since both feet are on the same upper member, the pump can be stepped on only by shifting the weight, and the legs are not tired. Further, since there is no need to provide a spring for returning the airtight member to the extended state, the stepping force is reduced. In addition, since the one-way valves for suction and discharge are provided on the vertical surface, they do not obstruct the stepped portion on the top plate. And since it is not necessary to provide a one-way valve in the airtight member, the shape of the airtight member is not complicated and the expansion and contraction operation is not hindered. Furthermore,

The divided portions on the suction side and the discharge side are divided into a suction portion and a discharge portion. And since each part is electrically connected to the outside through the opening formed in the front vertical surface part and the rear vertical surface part, the suction and discharge systems connected to the outside are each one system. As a result, it becomes possible to supply air or the like only by connecting one hose to the discharge system, and the operability is improved.

弁９が閉）。With the above configuration, the foot pump operates as follows. For example, when air is introduced into a rubber boat using the present pump, the opening holes of the discharge valves 8 and 9 and the suction port of the rubber boat are connected by a connection hose 20 having one end bifurcated as shown in FIG. Connecting. However, since a rubber boat usually has at least two air inlets, two hoses 21 having one connection port at both ends as shown in FIG. 2B are used, and two hoses 21 are separately provided in two air chambers of the rubber boat. It is also possible to combine them and send air at the same time. By doing so, the degree of entry of air into each air chamber is balanced, so that the filling of air becomes easy and it is also good for a rubber boat. When the hose is connected, a person goes up on the upper member 2 with both feet, alternately transfers weight to each foot, and pushes down both sides of the upper member 2 alternately. At this time, the upper member 2
Stops against the stoppers 12 and 13 as shown in FIG. 3, and the volume of the bellows 4 and 5 changes. When the volume decreases, the suction valves 6 and 7 close, the discharge valves 8 and 9 open, and air is sent to the rubber boat. When the volume increases, the discharge valves 8 and 9 conversely close, The intake valves 6 and 7 are opened to suck air from the outside into the bellows portion (in the state of the solid line in the figure, the intake valve 6 is closed and the discharge valve 8 is opened on the space 2b side, and the suction valve 7 is opened on the space 2c side). Is open and the discharge valve 9 is closed).

られることもない。 [0012] According to such a pump, it is possible to supply twice as much air as the conventional pump only by shifting the body weight.
Legs are not tired and air supply efficiency is good. Also, when one side is compressed, the volume of the bellows portion is automatically increased on the opposite side and air is sucked, so that it is not necessary to extend the bellows by a spring unlike a one-legged pump. Therefore, the force for opposing the spring is not required, and the air supply by stepping is further facilitated, and the spring does not always pull the bellows when not in use, and does not apply unnecessary stress to the bellows. Also improves durability. In addition, the suction valves 6 and 7 and the discharge valves 8 and 9 are
f, so that the step on the top plate 21 is not obstructed.
do not become. And it is not necessary to provide valves on the bellows 4,5.
So that the bellows shape is not complicated and its expansion and contraction is hindered.
I can't do that.

The upper member 2 and the lower member 3 are fixed by 2 and 13.
With this configuration, the bellows are not forcibly stretched or contracted, and the bellows have improved durability. In addition,
For example, when this pump is used for filling a rubber boat with air, it is desirable to bring the pump into the boat so that air leakage during the use of the boat can be compensated. People often give up pumps. However, if the pump can be fixed by a stopper as in the present pump, it can be used as a seat in a boat. When air leaks from the sea, air filling becomes possible, and the seating of an unstable air cushion becomes unnecessary, and the effect of three birds per stone is produced. Furthermore, if this double-acting pump is carried into a boat, it is possible to transfer weight while sitting on the pump inside the boat, so that the boat in use can be easily filled with air. Thus, the effect of greatly improving the safety is obtained.
