[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the power system of the pressure accumulating bicycle according to the present invention includes one liquid reservoir 10, a pair of pressurizing pumps 20, 30, a pair of pressure accumulating cylinders 40, 50, and a pair of pressure accumulating cylinders 40, 50. It has fluid turbines 60 and 70.

The pressurizing pumps 20, 30, the pressure accumulating cylinders 40, 50, and the fluid turbines 60, 70 are divided into similar sets, each of which is connected to the liquid storage tank 10. Since the operation and operation are the same, only one set, that is, the pressure pump 20, the accumulator cylinder 40, and the liquid turbine 60 will be described below.

In the liquid storage tank 10, a fluid (for example, power oil) having a viscosity of a predetermined value, which can be compressed to accumulate pressure (conserve pressure energy), is incorporated.

At least one supply pipe 11 and at least one return pipe 12 are connected to the liquid storage tank 10. The supply pipe 11 is connected to the inflow port 24 of the pressure pump 20, and the fluid flows from the fluid storage tank 10 to the pressure pump 20 only in one direction by the first check valve 11 </ b> A mounted in the supply pipe 11. .

An outlet 22 of the pressurizing pump 20 is connected to an inlet 41 of the accumulator cylinder 40 through a pressure pipe 23, and a second check valve 23 A provided in the pressure pipe 23 has a fluid pressure at a certain value. Is opened, the fluid flows from the pressurizing pump 20 through the pressure pipe 23 into the pressure accumulating cylinder 40. Under normal conditions, the pressure pump 20 is full of fluid.

Once the lever end 20 A of the pressure pump 20 is pressed, the fluid is pushed out of the fluid storage tank 10 and flows into the pressure pump 20 via the supply pipe 11. During the pressing step, a high pressure is generated in the fluid in the pressurizing pump 20, and the fluid flows out of the pressurizing pump 20 via the pressure pipe 23 against the blocking of the second check valve 23 </ b> A, and is stored in the accumulator cylinder 40. Flows into.

Here, in the present embodiment, the drive arm to which the force is applied has the booster lever 20B longer than the driven arm that is operated by the force. Since it is connected to the lever end 20A of the pressurizing pump 20, when the pressurizing pump 20 is pressed by the booster lever 20B, the force is amplified and converted. A return spring 21 is interposed between the lever end 20A and the pressurizing pump 20, and the elasticity thereof returns the lever end 20A to the original position.

The accumulator cylinder 40 stores the compressed high-pressure fluid therein. The transport pipe 42 is connected between the outlet of the accumulator cylinder 40 and the inlet 61 of the fluid turbine 60. One pressure gauge 44 is attached to the pressure accumulating cylinder 40, and measures the fluid pressure in the pressure accumulating cylinder 40.

A gate valve 43 is mounted in the transport pipe 42 to control a high-pressure accumulated fluid from the accumulator cylinder 40 to the fluid turbine 60 for a long time.

The fluid turbine 60 has a turbine rotor 62 in a sealed housing, the shaft of which is connected to the hub of one wheel. When high-pressure fluid flows into the turbine 60 and the blades of the turbine rotor 62 operate to rotate the rotor 62, the wheels also rotate to drive the bicycle.

The return pipe 12 is connected to an outlet 63 of the fluid turbine 60, and the fluid returns to the fluid storage tank 10 via the return pipe 12. The third check valve 12 </ b> A mounted in the return pipe 12 causes the fluid having reduced pressure to flow out of the outlet 63 of the turbine 60 and return to the fluid storage tank 10.

The gate valve 43 is connected to an operating lever 40B mounted on a handlebar 80 of the bicycle by a single lead wire 40A. When the operating lever 40B is grasped, the gate valve 43 opens.

[0020] In this way, the static energy stored in the compressed high-pressure fluid is converted into dynamic energy to drive the bicycle.

As shown in each figure, since two sets of power machines are installed in one bicycle, both the front and rear wheels of the bicycle can be separately driven by the fluid turbines 70 and 60.

The operation principle of the pressure accumulating bicycle according to the present invention will be described with reference to FIG.

The boosting levers 20B and 21B of the pressurizing pumps 20 and 21 are respectively mounted on the pedals of the frame F, and the two accumulator cylinders 40 and 41 are mounted on the frame F below the pedals.

The shafts of the rotors 62, 72 of the fluid turbines 60, 70 are respectively connected to the hubs of the front and rear wheels 81 and 82, and the corresponding operating levers 40B, 41B are also attached to the handlebar 80, respectively. Mounted with pressure gauges 44 and 45. The fluid storage tank 10, which is a pressure storage tank, is fixed to an appropriate place of the frame F.

In the pressure accumulating bicycle having such a structure, when a rider alternately steps on the boost levers 20B and 21B, energy is accumulated in the pressure accumulating cylinders 40 and 41, and the operating levers 40B and 41 can be gripped. For example, the stored static energy is converted into dynamic energy for driving a bicycle.

On the other hand, the rider must observe the pressure gauges 44 and 45 at all times and pay attention to the amount of remaining energy. If the residual energy is going to be exhausted, it is necessary to release the actuation levers 40B and 41B to stop the bicycle, step on the boost levers 20B and 21B alternately, and store the energy again.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the utility model registration request, and those skilled in the art can make modifications based on the present specification. Are included in the range.
