Abstract

A used oil drain system including a valve for being attached to the oil sump of an internal combustion engine; a used oil reservoir for being mounted relative to the internal combustion engine; and a passageway extending between the valve and the used oil reservoir for allowing used oil passing through the valve from the oil sump of the internal combustion engine when the valve is opened to pass to the used oil reservoir for storage. The valve may be screwed to the existing used oil drain port of the sump. The used oil reservoir may include a rigid container that is removably attached relative to the internal combustion engine.

Claims

1. A used oil drain system for internal combustion engines having an oil sump, said oil drain system comprising:

a) valve means for attachment to the oil sump of the internal combustion engine;

said valve means including a valve member having an opened position for allowing used oil to pass through said valve means from the oil sump of the internal combustion engine and having a closed position for preventing used oil from passing through said valve means from the oil sump of the internal combustion engine;

b) used oil reservoir means for mounting to the internal combustion engine; and

c) passageway means extending between said valve means and said used oil reservoir means for allowing used oil passing through said valve means from the oil sump of the internal combustion engine when said valve member is in said opened position to pass to said used oil reservoir means for storage;

said used oil reservoir means including carriage means for fixedly mounting to the internal combustion engine;

said used oil reservoir means including used oil container means for receiving used oil from said passageway means and for being removably attached to said carriage means, said used oil container means having a first position attached to said carriage means and a second position detached from said carriage means;

said used oil reservoir means including lock means for locking said used oil container means to said carriage means, said lock means including a lock member having a locked position for locking said used oil container means in said first position and having an unlocked position for allowing said used oil container means to move to said second position;

said used oil reservoir means including remote control means coupled to said lock member of said lock means for allowing said lock member to be moved to said unlocked position from a location remote from said carriage means.

2. The used oil drain system of claim 1 in which said remote control means of said used oil reservoir means includes cable means having first and second ends for moving said lock member of said lock means to said unlocked position when said second end thereof is pulled, said first end of said cable means being attached to said lock member, said second end of said cable means being positioned at a location remote from said carriage means.

3. The used oil drain system of claim 2 in which said lock means includes urging means for urging said lock member thereof to said locked position.

4. The used oil drain system of claim 1 in which said used oil reservoir means includes urging means for urging said used oil container means to said second position when said lock member of said lock means is moved to said unlocked position.

5. A used oil drain system for use in combination with a vehicle having a chassis, having an internal combustion engine with an oil sump, and having an interior with a seat for the driver thereof;

said oil drain system comprising;

a) valve means for attachment to said oil sump of said internal combustion engine;

said valve means including a valve member having an opened position for allowing used oil to pass through said valve means from said oil sump of said internal combustion engine and having a closed position for preventing used oil from passing through said valve means from said oil sump of said internal combustion engine;

said valve means including remote control means coupled to said valve member for allowing said valve member to be moved between said opened and closed positions from a location within said interior of said vehicle;

said remote control means including cable means having first and second ends for moving said valve member to said opened position when said second end thereof is pulled, said first end of said cable means being attached to said valve member, said second end of said cable means being positioned within said interior of said vehicle;

said valve means includes urging means for urging said valve member thereof to said closed position;

b) used oil reservoir means for mounting to said internal combustion engine;

said used oil reservoir means including carriage means for fixedly mounting to said chassis of said vehicle;

said used oil reservoir means including used oil container means for receiving the used oil from said valve means and for being removably attached to said carriage means, said used oil container means having a first position attached to said carriage means and a second position detached from said carriage means;

said used oil reservoir means including lock means for locking said used oil container means to said carriage means, said lock means including a lock member having a locked position for locking said used oil container means in said first position and having an unlocked position for allowing said used oil container means to move to said second position;

said used oil reservoir means including remote control means coupled to said lock member of said lock means for allowing said lock member to be moved to said unlocked position from a location within said interior of said vehicle;

said remote control means including cable means having first and second ends for moving said lock member of said lock means to said unlocked position when said second end thereof is pulled, said first end of said cable means being attached to said lock member, said second end of said cable means being positioned within said interior of said vehicle;

said lock means including urging means for urging said lock member thereof to said closed position;

said used oil reservoir means including urging means for urging said used oil container means to said second position when said lock member of said lock means is moved to said unlocked position; and

c) passageway means extending between said valve means and said used oil reservoir means for allowing the used oil passing through said valve means from said oil sump of said internal combustion engine when said valve member is in said opened position to pass to said used oil reservoir means for storage;

said passageway means including pump means for pumping used oil from said oil sump of said internal combustion engine, through said valve means, and to said used oil reservoir means for storage when said valve member of said valve means is in said opened position.
