AI Technical Summary

Benefits of technology

"The present invention is a pump for inflating inflatable bodies that does not require electric power and provides a substantial rate of inflation. It uses manual power applied through a hand crank and a gearbox with a high gear ratio to generate a jet of air to inflate the body. The pump is safe, cost-effective, and can be used in any environment. It includes a foldable crank, gearbox, fan, air inlet and outlet, and a detachable air hose with nozzle adapters. Different devices can be attached to the crank and gearbox such as a electric generator for powering electronic devices."

Problems solved by technology

Inflatable bodies, such as air beds and the like often require a considerable amount of pressurized air to fully inflate the body.
However, electric pumps require a source of electric power and foot powered pumps often to not provide a sufficient rate of inflation.
The pump is an environmentally conservative device as it costs nothing to operate—there are no batteries and no usage of electricity.
It is efficienct and costless.

Embodiment Construction

[0018]Referring to FIGS. 1-8, a pump 100 constructed according to the present invention includes a main housing 110, having first and second parts 1, 2. The main housing 110 partially encloses a sub-housing 120 having first and second parts 7, 21 and a middle portion 18. The sub-housing 120 encloses a gearbox 250 with a gear train. The sub-housing also encloses a fan 19. The first part 1 of the main housing 110 has an opening 130 in a wall 140 thereof, through which a first end 150 of the sub-housing 120 projects. The second part 2 of the main housing has an air inlet opening 160 in a wall 170 thereof through which an air intake 22 of the second half 21 of the sub-housing 120 projects. When connected together, each of the second part 21 and the middle portion 18 of the sub-housing 120 form a air outlet 180. In addition, the first and second parts 1, 2 of the main housing 110 form a main air outlet 190 which is in fluid communication with the fan outlet 180.

Abstract

A manual hand crank pump has a housing with an inlet and an outlet and has a gearbox with an input and an output and a rotation speed of the output is greater than 50 or 100 times a rotation speed of said input. A hand crank connected to and operable to drive said input of said gearbox and a fan is within the housing and is connected to the output of the gearbox and is operable to pump air from the inlet to the outlet. The gearbox has a gear train with first and second single gears and first, second, third and forth composite gears, each composite gear having a small gear and a large gear coaxial with said small gear which provide an aggregate gear ration of more than 1:50 or more than 1:100. The hank crank pivots between a stored position and an operating position.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 987,833, filed Nov. 14, 2007.FIELD OF THE INVENTION[0002]The invention pertains to pumps and, in particular, to manual pumps.BACKGROUND AND SUMMARY OF THE INVENTION[0003]Inflatable bodies, such as air beds and the like often require a considerable amount of pressurized air to fully inflate the body. Therefore, it is desirable and convenient to use a pump to inflate the body. It is known to use electric powered pumps or foot powered pumps for this purpose. However, electric pumps require a source of electric power and foot powered pumps often to not provide a sufficient rate of inflation. Therefore, what is desired is a pump for inflating inflatable bodies which does not require electric power and provides a substantial rate of inflation.[0004]The pump constructed according to the present invention uses manual power applied through a hand crank. A gearbox within the pump p...
