Abstract
Abstract A multi-functional implement useful as a portable automobile accessory which includes a main casing and an air functional portion mounted in the main casing. The air functional portion includes a first mechanism for blowing air outwardly of the main casing and a second mechanism for pumping air under pressure outwardly of the main casing. A motor having an output shaft extending in a longitudinal direction is movably mounted in a frame which is mounted in the main casing such that the motor is movable back and forth in the longitudinal direction. A lever is pivotably mounted to the main casing and connected to the motor for moving the motor between a first position at which the motor is engageable with the first mechanism to effect blowing of air outwardly of the main casing and a second position at which the motor is engageable with the second mechanism to effect pumping of air under pressure outwardly of the main casing. The lever extends outwardly of the main casing to allow manual movement of the motor by means of the lever between the first and second positions. A light functional portion including a light casing pivotally connected to the main casing includes a bright light and a warning light which flashes intermittently. Flexible hoses are provided for pumping air or blowing air out of the main casing and a flexible hose is provided for sucking air into a dust collecting compartment.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
234 words
A multi-function implement useful as a portable automobile accessory, comprising: a main casing; an air functional portion mounted in said main casing, said air functional portion including a first means for blowing air outwardly of said main casing and a second means for pumping air under pressure outwardly of said main casing; a motor having an output shaft extending in a longitudinal direction, said motor being mounted in a frame mounted in said main casing, said motor being movable back and forth in said longitudinal direction; a lever pivotably mounted to said main casing and connected to said motor for moving said motor between a first position at which said motor is engageable with said first means to effect blowing of air outwardly of said main casing and a second position at which said motor is engageable with said second means to effect pumping of air under pressure outwardly of said main casing, said lever extending outwardly of said main casing to allow manual movement of said motor by means of said lever between said first and second positions; and a light functional portion including an illuminating part and a warning-light part disposed in a light casing connected to said main casing, said light casing being connected to said main casing by two levers, each end of each of said two levers being respectively pivotally connected to said light casing and said main casing.
Claim 2
Dependent Claim
234 words
A multi-function implement useful as a portable automobile accessory, comprising: a main casing; an air functional portion mounted in said main casing, said air functional portion including a first means for blowing air outwardly of said main casing and a second means for pumping air under pressure outwardly of said main casing; a motor having an output shaft extending in a longitudinal direction, said motor being mounted in a frame mounted in said main casing, said motor being movable back and forth in said longitudinal direction; a lever pivotably mounted to said main casing and connected to said motor for moving said motor between a first position at which said motor is engageable with said first means to effect blowing of air outwardly of said main casing and a second position at which said motor is engageable with said second means to effect pumping of air under pressure outwardly of said main casing, said lever extending outwardly of said main casing to allow manual movement of said motor by means of said lever between said first and second positions; and a light functional portion including an illuminating part and a warning-light part disposed in a light casing connected to said main casing, said light casing being connected to said main casing by two levers, each end of each of said two levers being respectively pivotally connected to said light casing and said main casing.
Claim 3
Dependent Claim
60 words
The implement of claim 1, wherein said output shaft of said motor includes a disc clutch, said first means including a propeller and a head mounted on a transmission rod for rotation therewith, said head being engageable with said disc clutch when said motor is in said first position to thereby effect blowing of air outwardly of said main casing.
Claim 4
Dependent Claim
46 words
The implement of claim 2, wherein said first means further includes an air blowing outlet in said main casing, said outlet being connected to a propeller chamber in which said propeller is disposed whereby air can be blown outwardly of said main casing through said outlet.
Claim 5
Dependent Claim
18 words
The implement of claim 3, further including a flexible hose having an end thereof attachable to said outlet.
Claim 6
Dependent Claim
68 words
The implement of claim 1, wherein said output shaft of said motor includes a drive gear thereon, said second means including an air pump and means for driving a piston of said air pump, said piston driving means including a driven gear engageable with said drive gear when said motor is in said second position to thereby effect pumping of air under pressure outwardly of said main casing.
Claim 7
Dependent Claim
38 words
The implement of claim 5, wherein said second means further includes an exhaust valve connected to said pump and a hose having an inflating valve connected to said exhaust valve for pumping air under pressure into a tire.
Claim 8
Dependent Claim
50 words
The implement of claim 6, wherein said second means further includes a branch hose connected to said hose and an air pressure meter whereby air pressure in a tire can be determined by reading said air pressure meter when said inflating valve is connected to a valve of a tire.
Claim 9
Dependent Claim
77 words
The implement of claim 3, further including a fan casing defining a dust collecting chamber extending from said main casing, said fan casing having an inlet therein for passage of air therethrough due to operation of said first means, said fan casing further including a filter covering an opening in said main casing to said propeller chamber whereby dust is prevented from entering said propeller chamber and clean air can be blown outwardly from said main casing.
Claim 10
Dependent Claim
22 words
The implement of claim 8, further including a flexible hose having an end thereof attachable to said inlet in said fan casing.
Claim 11
Dependent Claim
29 words
The implement of claim 1, further including a light functional portion including an illuminating part and a warning-light part disposed in a light casing connected to said main casing.
Claim 12
