1. A portable hatch fan device which fits adjustably and removably into a variety of types and sizes of hatch openings on boat decks and recreational vehicle roofs, the device comprising:
- a fan holder frame comprising a center fan holding structure for securing a motorized fan to the fan holder frame and a peripheral frame edge configured to contact a hatch frame;
at least one pair of clamps each of the clamps slidably attached to the fan holder frame to position the clamp adjacent to one of at least two first opposing hatch frame sides of any of a variety of hatch frame opening sizes, each of the clamps lockable in a desired position for engaging the hatch frame side;
each of the clamps comprising a spring loaded clamp post and a horizontal clamp plate attached to the clamp post so that the horizontal clamp plate is movable between a first position biased against a surface of the hatch frame of a hatch having any of a variety of thicknesses of hatch frames to sandwich the hatch frame between the horizontal clamp plate and the peripheral frame edge to secure the portable hatch fan device to the hatch frame and a second position elevated above the hatch frame and pivoted horizontally out of alignment with the hatch frame to allow the fan to be moved into or out of the hatch; and
at least one pair of guide plates each of the guides slidably attached to the fan holder frame to position the clamp adjacent to one of at least two second opposing hatch frame sides of any of a variety of hatch frame opening sizes, each of the guide plates lockable in a desired position for engaging the hatch frame side for engaging an inner face of the hatch frame side so that the pair of guide plates work in conjunction with the pair of clamps to guide the portable hatch fan device during installation to center the fan in the hatch for blowing outside air into an interior space with a hatch cover open, the device being removable to close the hatch cover.

10. A portable hatch fan device which fits adjustably into a variety of types and sizes of hatch openings on boat decks and recreational vehicle roofs, the device comprising:
-
a fan holder frame comprising a center fan holding structure for securing a motorized fan to the fan holder frame and a peripheral frame edge having a flat horizontal top surface to contact a bottom surface of a hatch frame surrounding a hatch opening, and at least one track adjacent to each side edge of the fan holder frame perpendicular, to the edge; a pair of clamps each attached by a slidable and lockable guide plate connection to at least one track on each of two first opposing side edges of the fan holder frame so that each of the pair of clamps is slidable in at least one track to position the clamp adjacent to one of two first opposing hatch frame sides of any of a variety of hatch frame opening sizes, each of the pair of clamps lockable in the track in a desired position for engaging the hatch frame side;
each of the pair of clamps comprising a clamp base sleeve lockable to the track and a vertical post having a horizontal clamp plate attached to a top of the vertical post, the vertical post attached to the clamp base sleeve by a means for vertically sliding and horizontally pivoting the vertical post relative to the clamp base sleeve, and a means for biasing the vertical post normally in a downward position under tension so that the horizontal clamp plate is movable between a first position biased against a top surface of the hatch frame of a hatch having any of a variety of thicknesses of hatch frames, the clamp post adjustable in height to engage a top surface of the frame side of the one of the two first opposing hatch frame sides sandwiching the hatch frame between the horizontal clamp plate and the peripheral frame edge to secure the portable hatch fan device to the hatch frame and a second position elevated above the hatch frame and pivoted horizontally out of alignment with the hatch frame to allow the fan to be moved into or out of the hatch; anda pair of clamp guide plates permanently attached to the clamp base sleeve and each attached by a slidable and lockable guide plate connection to at least one track on each of two second opposing side edges of the fan holder frame so that each of the pair of clamp guide plates being slidable in the at least one track to position the guide plate in contact with one of two second opposing hatch frame sides of any of a variety of hatch frame opening sizes, each of the pair of clamp guide plates being lockable in the track in a desired position for engaging an inner face of the hatch frame side so that the pair of clamp guide plates work in conjunction with the pair of clamps plates to guide the portable hatch fan device during installation to center the fan in the hatch for blowing outside air into an interior space with a hatch cover open, the device being removable to close the hatch cover; a pair of guides each attached by a slidable and lockable guide connection to at least one track on each of two second opposing side edges of the fan holder frame so that each of the pair of guides being slidable in at least one track to position the guide in contact with one of two second opposing hatch frame sides of any of a variety of hatch frame opening sizes, each of the pair of guides being lockable in the track in a desired position for engaging an inner face of the hatch frame side so that the pair of guides work in conjunction with the pair of clamp guide plates to guide the portable hatch fan device during installation to center the fan in the hatch for blowing outside air into an interior space with a hatch cover open, the device being removable to close the hatch cover. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
