Abstract
Abstract This invention concerns a car cleaner and air pump shaped like an elephant. It can be used as a vacuum cleaner, e.g. sucking in dirt, and at the same time as an air pump, e.g. pumping pressurized air into a tire. This elephant-shaped car cleaner and air pump consists of an elephant-shaped cover, a dirt sucking device, an air pumping device, a lighting signaling device and an electric power system. The characteristic of the dirt sucking device is that dirt is sucked through the trunk and collected in the dirt bag set in the body by means of a blowing wheel turned by a motor. The characteristic of the air pumping device lies in pumping air by means of a cylinder and a piston that is moved by a set of worm-gear wheel and rod turned by the same motor that is used in the dirt sucking device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
An elephant-shaped car vacuum cleaner and air pump, including: an elephant-shaped cover, a dirt suction device consisting of an inlet passage, a motor, an impeller driven by the motor, and a dirt bag; an air pumping device consisting of said motor, a transmission consisting of a worm gear rod, a worm-gear wheel, and an eccentric crank; and a cylinder with a piston driven by said transmission; a lighting and colored-light signaling device, and an electric power system; having the characteristics that dirt can be suctioned and collected in the dirt bag through said inlet passage in a trunk of said cover by the suction created by the impeller turned by the motor; and that air can be pumped by compressing the air coming into the cylinder through an exhaust pipe from the impeller by means of the piston driven by the transmission.
Claim 2
Dependent Claim
142 words
An elephant-shaped car vacuum cleaner and air pump, including: an elephant-shaped cover, a dirt suction device consisting of an inlet passage, a motor, an impeller driven by the motor, and a dirt bag; an air pumping device consisting of said motor, a transmission consisting of a worm gear rod, a worm-gear wheel, and an eccentric crank; and a cylinder with a piston driven by said transmission; a lighting and colored-light signaling device, and an electric power system; having the characteristics that dirt can be suctioned and collected in the dirt bag through said inlet passage in a trunk of said cover by the suction created by the impeller turned by the motor; and that air can be pumped by compressing the air coming into the cylinder through an exhaust pipe from the impeller by means of the piston driven by the transmission.
Claim 3
Dependent Claim
94 words
The elephant-shaped car vacuum and air pump as set forth in claim 1, wherein the head portion of the cover is able to be lifted open for cleaning and emptying the dirt bag, and the body portion of the cover has on its upper surface a pressure gauge and a circular valve for closing or venting the air chamber to the atmosphere, so that for pumping air into a tire, the valve can be closed to make the air flow into the cylinder, and the air pressure in the cylinder indicated by the gauge.
Claim 4
Dependent Claim
56 words
The elephant-shaped car vacuum and air pump as set forth in claim 1, wherein the lighting or colored-light signalling is accomplished by at least one light set into at least one eye in a head portion of the cover, and covered by a multi-colored lens able to change its color from red to green or transparent.
