Adjustable air vent for a vehicle
View Patent ↗In a snowmobile or other vehicle, ventilation of ambient air to the engine compartment is necessary. However, from time to time when encountering deep snow or extremely cold temperatures, it may be necessary to restrict the inflow of ambient air into the engine compartment. An adjustable air vent having a sliding ventilation grill adjusts the air flow. The air vent has actuators for adjusting the air flow that are simple and easily manually operable by an operator even when wearing gloves or mittens without the need of any tools.
1. An adjustable air vent for a vehicle, comprising:
a stationary grill adapted to be mounted to the vehicle, the stationary grill having at least one air aperture and an engaging surface; and
a movable grill adapted to be movably mounted with respect to the stationary grill, the movable grill having at least one air aperture and an engaging surface adapted to engage the engaging surface of the stationary grill, the movable grill movable with respect to the stationary grill from an open position where the ay least one aperture of the stationary grill is aligned with the at least one aperture of the moveable grill to allow air to flow therethrough to a closed position, where the at least one aperture of the stationary grill is not aligned with the at least one aperture of the moveable grill to reduce the flow of air through the vent, the movable grill including at least one projecting actuator suitable for moving the movable grill between the open position and the closed position, wherein the movable grill and the at least one projecting actuator are integrally molded from plastic material.
2. The adjustable air vent of claim 1 , further comprising:
a lock for maintaining a desired position of the movable grill.
3. The adjustable air vent of claim 2 , wherein the lock comprises a frictional engagement member for frictionally engaging the movable grill to maintain the desired position of the movable grill.
4. The adjustable air veto of claim 1 , wherein the stationary grill includes a plurality of projecting guide posts adapted to position the movable grill and guide movement of the movable grill.
5. The adjustable air vent of claim 4 , wherein the stationary grill further includes at least one fastener attached to at least one of the guide posts for engaging the movable grill to secure it to the stationary grill.
6. The adjustable air vent of claim 1 , wherein the stationary grill is part of a hood of the vehicle.
7. The adjustable air vent of claim 6 , wherein the vehicle is a snowmobile.
8. A snowmobile, comprising:
a engine for driving the snowmobile;
an air path from an exterior of the snowmobile to an engine compartment; and
an adjustable air vent mounted in the air path, the adjustable air vent comprising:
a stationary grill adapted to be mounted to the vehicle, the stationary grill having at least one air aperture and an engaging surface; and
a movable grill adapted to be movably mounted with respect to the stationary grill, the movable grill having at least one air aperture and an engaging surface adapted to engage the engaging surface of the stationary grill, the movable grill movable with respect to the stationary grill from an open position, where the at least one aperture of the stationary grill is aligned with the at least one aperture of the moveable grill to allow air to flow therethrough, to a closed positions where the at least one aperture of the stationary grill is not aligned with the at least one aperture of the movable grill to reduce the flow of air through the vent, the movable grill including at least one projecting actuator suitable for moving the movable grill between the open position and the closed position, wherein the movable grill and the at least one projecting actuator are integrally molded from a plastic material.
9. The snowmobile of claim 8 , further comprising:
a lock for maintaining a desired position of the movable grill.
10. The snowmobile of claim 9 , wherein the lock comprises a frictional engagement member for frictionally engaging the movable grill to maintain the desired position of the movable grill.
11. The snowmobile of clam 8 , wherein the stationary grill includes a plurality of projecting guide posts adapted to position the movable grill and guide movement of the movable grill.
12. The snowmobile of claim 11 , wherein the stationary grill further includes at least on fastener attached to at least on of the guide posts for engaging the movable grill to secure it to the stationary grill.
13. The snowmobile of claim 8 , wherein the stationary grill is part of a hood of the vehicle.
