Automobile litter evacuation system

Claim 2

In combination with a vehicle having a passenger compartment and an air ventilating and heating system for said passenger compartment, said air ventilating and heating system comprising a blower, an intake housing having an air inlet opening through which air is drawn by said blower, an outlet housing through which air is directed by said blower into said passenger compartment, and a heater through which air can be selectively directed for heating the air passing into the passenger compartment, a litter evacuation system to remove litter from said passenger compartment, said system comprising: a. a litter receptacle means mounted to said vehicle for collection and retention of litter from the passenger compartment, b. a removal tube means leading from said passenger compartment to said receptacle, c. air suction means leading from said receptacle means to said intake housing and arranged to draw air from said receptacle means while leaving litter therein, and d. activating means to cause operation of said blower to create a suction in said vehicle housing and thus cause an inflow of air through said removal tube means into said receptacle means, through said suction means, and into said intake housing, whereby litter placed in said removal tube means is moved by air flow therethrough into said receptacle means, with air being recirculated from said passenger compartment through said litter removal system for litter removal, and through said air ventilating system back to the passenger compartment, and with litter remaining in said litter receptacle means.

Claim 3

The system as recited in claim 1, wherein there is a closure valve for the inlet opening of the vehicle intake housing, and means to move said valve to its closed position to at least partially block said inlet opening during operation of said system.

Claim 4

The system as recited in claim 2, wherein said activating means and said valve closure means are operatively interconnected, whereby operation of one of said activating means causes operation of the closure means so that said blower operates at the same time that said closure valve for the intake opening is in its closed position.

Claim 5

The system as recited in claim 3, wherein there is a closure means for said removal tube means to close said removal tube means from said passenger compartment, and switch means operable by movement of said closure means to close said intake opening closure valve and activate said blower.

Claim 6

The system as recited in claim 4, wherein said switch means is arranged to operate by opening of said closure means.

Claim 7

The system as recited in claim 4, wherein said switch means is caused to be operated by closing of said closure means.

Claim 8

The system as recited in claim 6, wherein said switch means is a time delay switch means, whereby after said closure means is moved to operate said switch means, said switch means is deactivated after a predetermined period of time to deactivate said system.

Claim 9

The system as recited in claim 2, wherein said closure valve comprises a plate member swing mounted to move to its closed position adjacent said air inlet opening and to an open position spaced from said inlet opening.

Claim 10

The system as recited in claim 1, wherein said suction means comprises a tube leading from said receptacle means to said intake housing, and there is check valve means to prevent backflow of air from said intake housing into the receptacle and back to the passenger compartment.

Claim 11

The system as recited in claim 1, wherein said litter receptacle means comprises a container having a lid closing the container, and said removal tube is connected to said lid, said system further comprising hinge means mounted to said removal tube to permit a portion of said removal tube to be swung upwardly with said lid so as to have said container open for removal of litter therefrom.

Claim 12

The system as recited in claim 1, further comprising as ash tray container connected to an inlet portion of said removal tube means, said ash tray container having a cylindrical configuration about a longitudinal axis, with a longitudinal axis of the ash tray container aligned with said removal tube means, whereby debris such as cigarette butts becomes properly aligned in the ash tray for proper travel through said removal tube means.

Claim 13

The system as recited in claim 1, wherein said litter receptacle means comprises a container, a perforate member upstanding in said container, and a suction tube leading from said perforate member, whereby litter, such as ash tray litter, entering said container, falls to the bottom of the container, with air in the container being drawn through said perforate member and through said suction tube.

Claim 14

The system as recited in claim 1, wherein said removal tube means comprises a tube having a uniform cylindrical cross section, with an interior diameter approximately three-eighths to three-sixteenths larger than the diameter of cylindrical refuse, such as beverage containers, which are to travel as litter through the tube, whereby proper travel of such refuse containers is facilitated through the removal tube means.

Claim 15

The system as recited in claim 13, wherein the inside diameter of said removal tube means is less than three and a quarter inches and greater than two and three-quarter inches.

Claim 16

The system as recited in claim 14, wherein the inside diameter of said removal tube means is approximately three inches.

Claim 17

In combination with a vehicle having a passenger compartment and an air ventilating and heating system for said passenger compartment, said air ventilating and heating system comprising a blower, an intake housing having an air inlet opening through which air is drawn by said blower, an outlet housing through which air is directed by said passenger compartment, and a heater through which air can be selectively directed for heating the air passing into the passenger compartment, a litter evacuation system to remove litter from said passenger compartment, said system comprising: a. a separate litter receptacle means including a cover therefor mounted to said vehicle for collection and retention of litter from the passenger compartment, b. a removal tube means leading from said passenger compartment to the cover of said receptacle, c. air suction means leading from the cover of said receptacle means to said intake housing and arranged to draw air from said receptacle means while leaving litter therein, and d. activating means to cause operation of said blower to create a suction in said vehicle housing and thus cause an inflow of air through said removal tube means into said receptacle means, through said suction means, and into said intake housing, whereby litter placed in said removal tube means is moved by air flow therethrough into said receptacle means, with air being recirculated from said passenger compartment through said litter removal system for litter removal, and through said air ventilating system back to the passenger compartment, and with litter remaining in said litter receptacle means.

Claim 18

In combination with a vehicle having a passenger compartment and an air ventilating and heating system for said passenger compartment, said air ventilating and heating system comprising a blower, an intake housing having an air inlet opening through which air is drawn by said blower, an outlet housing through which air is directed by said passenger compartment, and a heater through which air can be selectively directed for heating the air passing into the passenger compartment, a litter evacuation system to remove litter from said passenger compartment, said system comprising: a. a separate litter receptacle means including a cover therefor mounted to said vehicle for collection and retention of litter from the passenger compartment, b. a removal tube means leading from said passenger compartment to the cover of said receptacle, c. air suction means leading from the cover of said receptacle means to said intake housing and arranged to draw air from said receptacle means while leaving litter therein, and d. activating means to cause operation of said blower to create a suction in said vehicle housing and thus cause an inflow of air through said removal tube means into said receptacle means, through said suction means, and into said intake housing, whereby litter placed in said removal tube means is moved by air flow therethrough into said receptacle means, with air being recirculated from said passenger compartment through said litter removal system for litter removal, and through said air ventilating system back to the passenger compartment, and with litter remaining in said litter receptacle means.
