Abstract: A vent for mobile living quarters has a base and a cover coupled to the base. The cover is connected to the base and pivots about a hinge by a mechanism that is coupled to a moving bar. The moving bar is attached to the cover by fasteners on one end and an alignment tab on the opposite end. The cover is user-replaceable from the top side without having to move or disconnect the mechanism. To replace the cover, fasteners are removed and the cover is pivoted away from the moving bar, where the alignment tab disengages from the cover. The cover is then slidable along the hinge to completely remove the cover from the base. A new replacement cover is slid along the hinge and the alignment tab is engaged with the replacement cover. The cover is pivoted down to a closed position and the fasteners are reinstalled.

Abstract: A shelter and storage pod system is provided comprising a pod comprising a top wall, a bottom wall and four sidewalls, where the pod is structurally divided into a top portion and a bottom portion. A first hinge couples the top portion to the bottom portion. One or more ventilation ports are structurally integrated into the top wall, bottom wall, four sidewalls or any combination thereof. A reinforcing frame member is coupled to the bottom wall and comprises a yoke arm and a plurality of wheels coupled thereto. A bedding substrate is disposed adjacent and orthogonal to the four sidewalls, where the bedding substrate is coupled to one sidewall via a second hinge. One or more vertical frame walls define a plurality of storage compartments disposed under the bedding substrate, where the one or more vertical frame walls structurally support the bedding substrate. An adjustable coupling sleeve operatively couples to the reinforcing frame member via the yoke arm.

Abstract: An opening and closing device of an air vent for a vehicle is provided for raising or lowering the air vent so as to open or close a ventilating part. The opening and closing device includes first and second link parts rotatably provided at both sides of the ventilating part, a hydraulic cylinder part having one side fixed to the air vent and the other side connected to the first link part, a piston rod part having one side connected to the second link part and the other side slidably coupled to the hydraulic cylinder part, and an adjusting part fixing the piston rod part to not slide into the hydraulic cylinder part or release the piston rod part to be slidable.

Abstract: A flow of air coming out of a louver facing the internal space of the passenger compartment of a vehicle is oriented, exploiting the Coanda effect, in an area adjacent to a first surface of the passenger compartment or in an area adjacent to a second surface of the passenger compartment.

Abstract: A vent assembly has a base and a cover connected to the base. The cover moves between a closed and open position. A fan is optionally mounted for rotation in the base. A mechanism, including a strut system, raises and lowers the cover. The strut system is connected with the cover at two positions spaced from one another. When the cover is in its closed position, a retention force is provided by the strut system and is distributed about the cover.

Abstract: A collapsible air vent closure is disclosed comprising a frame having a frame aperture. A closure is mounted to the frame for pivoting between a closed position and an open position. A movable vent wall having a vent orifice is interposed between the frame and the closure. The vent orifice provides an air flow path to the frame aperture when the closure is in the open position. The closure inhibits the air flow path to the frame aperture when the closure is in the closed position.

Abstract: A vent assembly is provided for any manner of vehicle or vessel. The vent assembly includes a vent which is operable between selective open positions and a closed position. The vent is rotatable relative to a panel through which the vent is disposed so that the vent can act as a forced air vent or exhaust vent.

Abstract: A new exterior skylight solar screen cover for engaging a skylight to prevent excessive heat build-up in a space below a skylight which has a frame, the solar screen comprising a frame member dimensioned for coupling with the exterior of the skylight. A plurality of louvers laterally extend within the frame member and a solar screen panel is dimensioned for being received within the frame member. The solar screen panel comprises a peripheral frame that is positioned on an inwardly extending lip of the upper frame section of the solar screen cover.

Abstract: A vented window assembly is provided for any manner of vehicle or vessel. The window assembly has a unitary piece of glass with an opening defined therein. A vent assembly is mounted in the opening and is sealingly engaged with the glass. The vent assembly includes an operable vent which is selectively positioned between an opened position and a closed position. The vent is rotatable relative to the glass so that the vent can act as a forced air or exhaust vent.

Abstract: An improved solar operated ventilator cover is disclosed for covering an aperture disposed in a horizontal surface. The cover has sidewalls with a cover opening and a top surface with an internal wall extending between the sidewalls and the top wall. An orifice is defined in the internal wall for enabling the flow of air within the cover. An electric motor has a motor shaft with a fan blade positioned proximate the orifice. A photovoltaic cell is connected to the electric motor for rotating the fan blade proximate the orifice to establish the flow of air through the cover opening.

Abstract: A device is disclosed for shutting off the flow of exhaust gases from the exhaust outlet of a diesel engine having a substantially vertical exhaust stack. The device is especially useful for stopping the flow from one of twin diesel stacks when a tractor or truck having twin stacks from a single manifold is undergoing maintenance in an indoor facility. The device permits an operator standing on the floor to position a resilient pad in sealing engagement with a stack outlet twelve feet or more above floor level and lock the pad into position and to remove the device, again from ground level, when maintenance has been completed and the engine shut down.

Abstract: An apparatus is disclosed for an improved device for covering an aperture disposed on a horizontal surface. The cover has sidewalls, a top surface, and a lip which defines a cover opening within a sidewall. The improvement comprises a first and a second guide rail extending from the cover and disposed on opposed first and second sides of the cover opening. A slot is defined in the cover and disposed along a third side of the cover opening. A frame defines a screened window and includes fastener projections which extend outwardly from the frame. The frame is inserted within the slot with a first and a second side of the frame being guided by the first and second opposed guide rails. The fastener projections engage the lip of the cover opening for retaining the frame and the screened window within the cover opening.
