Abstract
A recreational vehicle vent (14,16) is formed of a streamlined body (12) having a forward fixed riser (14) and a movable cover (16) which, when closed, forms a smooth continuous aerodynamic surface together with the fixed riser. The cover is movably mounted to the vent frame by means of a pair of transversely extending crossed links (140,142) at the front and a second independent pair of transversely extending crossed links (200,202) at the back. The two link pairs are independently operated by geared actuators (180,206) so that either the front of the cover or the back of the cover can be independently lifted or both can be lifted together.
Claims32
A vent assembly for a vehicle having a ventilation opening formed in a wall thereof, said assembly comprising:
- a vent frame adapted to be mounted to said vehicle to frame said opening,
- a vent cover having a forward portion defining a cover front opening and having a rear portion,
- means for mounting said forward portion to said frame for motion between a forward portion lower position in which said cover front opening is adjacent said frame, and a cover forward portion upper position in which said cover front opening is displaced from said frame,
- a riser fixed to said frame adjacent said vent cover forward portion and configured and arranged to close said cover front opening when said cover forward portion is in said lower position and to direct air past the riser into said cover front opening when said cover forward portion is in said upper portion, said riser and cover forming a continuous low drag aerodynamic surface when said cover forward portion is in said lower position, and
- means for connecting said vent cover rear portion to said frame.
A vent assembly for a vehicle having a ventilation opening formed in a wall thereof, said assembly comprising:
- a vent frame adapted to be mounted to said vehicle to frame said opening,
- a vent cover having an open front defining a cover front opening and having a rear portion,
- a riser fixed to said frame forward of and adjacent said cover, said riser having a rear portion displaced from said frame and having a riser forward portion located forward of said frame,
- means for mounting said open front to said frame for motion between a cover front lower position in which said cover front opening is adjacent to and closed by said rear portion of said riser, and a cover front upper position in which said cover front opening is open and displaced from said riser rear portion, and
- means for connecting said vent cover rear portion to said frame.
A vent assembly for a vehicle having a ventilation opening formed in a wall thereof, said assembly comprising:
- a vent frame adapted to be mounted to said vehicle around said opening and having a front and a back,
- a vent cover configured and arranged to selectively cover said vehicle opening and having a front and back,
- a first pair of crossed links pivotally interconnected to each other at intermediate portions thereof and configured and arranged to movably connect said cover front to said frame front,
- a second pair of crossed links pivotally interconnected to each other at intermediate portions thereof and configured and arranged to movably connect said cover back to said frame back,
- a front actuator arm movably connected to said frame front and having an arm end,
- a front drive link connected between said front actuator arm end and said intermediate portions of said first pair of crossed links,
- means on said frame for driving said front actuator arm,
- a rear actuator arm movably connected to said back of said frame and having an actuator arm end,
- a back drive link connected between said second actuator arm end and said intermediate portions of said second pair of crossed links, and
- means on said frame for driving said rear actuator arm.
A vent assembly for a Vehicle having a ventilation opening formed in a wall thereof, said assembly comprising:
- a vent frame adapted to be mounted to said vehicle around said opening and having a front and back,
- a vent cover having a front and back,
- a first pair of flexible crossed and pivotally interconnected links movably connecting the front of the cover to the front of the frame for motion between a first position wherein the front of the cover is adjacent the frame and a second position in which the front of the cover is displaced from the frame,
- a second pair of flexible crossed and pivotally interconnected links interconnecting the back of the cover with the back of the frame for motion between a first position wherein the back of the cover is adjacent the back of the frame and a second position wherein the back of the cover is displaced from the back of the frame, and
- means for independently moving said first and second pairs of links.
