Vented drain for recreational vehicles

Claim 2

A vented drain for recreational vehicles comprising: means for coupling said vented drain to a drain line within said vehicle; a first conduit means communicating with said coupling for passing through a hole in the vehicle wall for delivery of drain water to the outside of the vehicle; a second conduit means for passing through a hole in the vehicle wall so as to define a vent air flow path therethrough; and a first baffle means defining first and second generally vertical vent air flow paths communicating with each other adjacent the top of said first baffle means, the lower portion of said first flow path communicating with said first conduit means, the lower portion of said second flow path communicating with said second conduit means, whereby outside vent air may pass through said second conduit means, up said second vertical flow path, down said first vertical flow path and into said first conduit means to vent said drain line.

Claim 3

The vented drain of claim 1 further comprised of a second baffle means disposed within said first conduit means protruding from the upper portion of said first conduit means and directed away from said coupling means generally under the junction of said first conduit means and said first vertical flow path to define a continuation of said first vertical flow path along said first conduit means.

Claim 4

The vented drain of claim 1 further comprised of a plastic nut wherein the region of said second conduit means adjacent the end thereof is threaded and said nut is threadedly engageable with said second conduit means to retain said vented drain with respect to the vehicle wall.

Claim 5

The vented drain of claim 1 further comprised of a plastic nut wherein the region of said first conduit means adjacent the end thereof is threaded and said nut is threadedly engageable with said first conduit means and retain said vented drain with respect to the vehicle wall.

Claim 6

The vented drain of claim 1 wherein said first and second conduit members pass through the same hole in the vehicle wall.

Claim 7

The vented drain of claim 5 wherein said first conduit member is disposed within said second conduit member, said flow path defined by said second conduit means being the space between said first and second conduit members.

Claim 8

The vented drain of claim 6 wherein said first and second conduit members are substantially concentric.

Claim 9

The vented drain of claim 7 further comprised of a threaded plastic member, wherein the region of said second conduit means adjacent the end thereof is threaded, said threaded plastic member having threads adapted to engage said threaded area on said second conduit member, said threaded plastic member further protruding radially inward to an area adjacent the outer surface of said first conduit member, said plastic member further being relieved so as to allow air flow therethrough between said first and second conduit members.

Claim 10

The vented drain of claim 1 wherein said first conduit member and said second conduit member are independent conduit members vertically adjacent each other.

Claim 11

A vented drain for recreational vehicles comprising: means for coupling said vented drain to a drain line within said vehicle; a first conduit means communicating with said coupling and adapted to pass through a hole in the vehicle wall for delivery of drain water to the outside of the vehicle, the area adjacent the end of said first conduit means being threaded; a second conduit means adapted for disposition adjacent the inner wall of said vehicle, said first conduit means passing through said second conduit means; a first baffle means defining first and second vertical flow paths communicating with each other adjacent the top of said first baffle means, the lower portion of said first flow path communicating with said first conduit means, the lower portion of said second flow path communicating with said second conduit means; a sliding member adapted to fit through a hole in the vehicle wall and slideably engage said second conduit means; threaded means for threadedly engaging the threaded portion of said first conduit member, said threaded means having an outer diameter which is larger than the hole through the vehicle wall, said threaded means having openings so as to allow air flow into the space between said sliding member and said inner conduit member, said threaded means being cooperative with said sliding member to define a flow path therein and to retain said vented drain with respect to the vehicle wall; and a means for slideably sealing said sliding member and said second conduit member to prevent air flow therebetween.

Claim 12

A vented drain for recreational vehicles comprising: means for coupling said vented drain to a drain line within said vehicle; a first conduit means communicating with said coupling and adapted to pass through a hole in the vehicle wall for delivery of drain water to the outside of the vehicle, the area adjacent the end of said first conduit means being threaded; a second conduit means adapted for disposition adjacent the inner wall of said vehicle, said first conduit means passing through said second conduit means; a first baffle means defining first and second vertical flow paths communicating with each other adjacent the top of said first baffle means, the lower portion of said first flow path communicating with said first conduit means, the lower portion of said second flow path communicating with said second conduit means; a sliding member adapted to fit through a hole in the vehicle wall and slideably engage said second conduit means; threaded means for threadedly engaging the threaded portion of said first conduit member, said threaded means having an outer diameter which is larger than the hole through the vehicle wall, said threaded means having openings so as to allow air flow into the space between said sliding member and said inner conduit member, said threaded means being cooperative with said sliding member to define a flow path therein and to retain said vented drain with respect to the vehicle wall; and a means for slideably sealing said sliding member and said second conduit member to prevent air flow therebetween.

Claim 13

The vented drain of claim 10 wherein said means for sealing comprises an O-ring member.

Claim 14

A vented drain for recreational vehicles comprising: means for coupling said vented drain to a drain line within said vehicle; a first conduit means communicating with said coupling and adapted to pass through a hole in the vehicle wall for delivery of drain water to the outside of the vehicle; a second conduit means adapted to pass through said hole in the vehicle wall so as to define a flow path therethrough, said first conduit member is disposed within said second conduit member, said flow path defined by said second conduit means being the space between said first and second conduit members, and a first baffle means defining first and second generally vertical flow paths communicating with each other adjacent the top of said first baffle means, the lower portion of said first flow path communicating with said first conduit means, the lower portion of said second flow path communicating with said second conduit means.

Claim 15

A vented drain for recreational vehicles comprising: means for coupling said vented drain to a drain line within said vehicle; a first conduit means communicating with said coupling and adapted to pass through a hole in the vehicle wall for delivery of drain water to the outside of the vehicle; a second conduit means adapted to pass through said hole in the vehicle wall so as to define a flow path therethrough, said first conduit member is disposed within said second conduit member, said flow path defined by said second conduit means being the space between said first and second conduit members, and a first baffle means defining first and second generally vertical flow paths communicating with each other adjacent the top of said first baffle means, the lower portion of said first flow path communicating with said first conduit means, the lower portion of said second flow path communicating with said second conduit means.
