Abstract
Abstract The invention is a car top boat carrying and loading device upon which a boat is preferably loaded and carried in an inverted position. It includes frame members mountable on top of a car; rails which are pivotably and removably attached at either side of the frame members to extend downward from the top and to the side of the car; rollers associated with the boat and rollable upon the frame members and rails; foldable supporting legs at the ends of the rails which in their opened position, extend downward preferably vertically from the ends of the rails to the ground; stops at the ends of the rails to prevent the boat from rolling off the ends thereof; and handles attached to the ends of the rails. The foldable legs are pivotally attached to the rails and removable resilient connectors are provided between the legs and rails. After the boat has been rolled off the frame members to the stops, the resilient connectors are stretched and attached between the legs and rails so that if the handles are used to lift the legs clear of the ground, the legs will be pulled up to a folded position. Thus, when the rails are lowered to the ground, the boat will be tipped to a relatively steep angle from which it may be easily uprighted and removed from the rails. In reloading the reverse procedure is used except that the resilient connectors are left unattached and when the handles are lifted, the legs swing to a generally vertical position by their own weight.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
320 words
A boat carrier mountable upon a motor vehicle and comprising: 1. a pair of parallel, generally horizontal cross members mountable on a vehicle roof and disposed to extend transversely of said roof, at least one end of the cross members terminating adjacent one side of the vehicle; 2. means detachably connecting the respective cross members to the vehicle; 3. a pair of elongated, parallel rails pivotally joined at one end to said ends of the respective cross members and extending laterally downwardly from said side of the vehicle as continuations of the respective cross members; 4. a series of rollers disposable in supporting relation to the boat to be carried, and positioned to rollably support said boat upon the rails and cross members; 5. a pair of legs pivotally attached to the respective rails at the other ends thereof for swinging movement between a collapsed position in which said legs underlie and extend alongside the respective rails to an extent sufficient for disposition of said other ends of the rails at ground level, and a rail-supporting position in which the legs extend vertically downwardly from the rails, the legs in the collapsed position thereof supporting the rails in a position of greater inclination from the horizontal than is assumed by the rails when the legs are in their rail-supporting positions; and 6. resiliently contractile means detachably connectable between said rails and the respective legs and tensioned to bias the legs from their rail-supporting to their collapsed positions whenever the legs are shifted vertically upwardly out of contact with the ground surface while in the rail-supporting positions thereof, said rails being pivotable upwardly from said positions of lesser inclination thereof to free the legs from contact with the ground surface, said legs being free to gravitate to their rail-supporting positions when the resiliently contractile means is disconnected and the rails are pivotally moved upwardly from said positions of lesser inclination thereof.

A boat carrier mountable upon a motor vehicle and comprising: 1. a pair of parallel, generally horizontal cross members mountable on a vehicle roof and disposed to extend transversely of said roof, at least one end of the cross members terminating adjacent one side of the vehicle; 2. means detachably connecting the respective cross members to the vehicle; 3. a pair of elongated, parallel rails pivotally joined at one end to said ends of the respective cross members and extending laterally downwardly from said side of the vehicle as continuations of the respective cross members; 4. a series of rollers disposable in supporting relation to the boat to be carried, and positioned to rollably support said boat upon the rails and cross members; 5. a pair of legs pivotally attached to the respective rails at the other ends thereof for swinging movement between a collapsed position in which said legs underlie and extend alongside the respective rails to an extent sufficient for disposition of said other ends of the rails at ground level, and a rail-supporting position in which the legs extend vertically downwardly from the rails, the legs in the collapsed position thereof supporting the rails in a position of greater inclination from the horizontal than is assumed by the rails when the legs are in their rail-supporting positions; and 6. resiliently contractile means detachably connectable between said rails and the respective legs and tensioned to bias the legs from their rail-supporting to their collapsed positions whenever the legs are shifted vertically upwardly out of contact with the ground surface while in the rail-supporting positions thereof, said rails being pivotable upwardly from said positions of lesser inclination thereof to free the legs from contact with the ground surface, said legs being free to gravitate to their rail-supporting positions when the resiliently contractile means is disconnected and the rails are pivotally moved upwardly from said positions of lesser inclination thereof.

a pair of elongated, parallel rails pivotally joined at one end to said ends of the respective cross members and extending laterally downwardly from said side of the vehicle as continuations of the respective cross members;
Claim 6
Dependent Claim
36 words
a pair of elongated, parallel rails pivotally joined at one end to said ends of the respective cross members and extending laterally downwardly from said side of the vehicle as continuations of the respective cross members;
Claim 7
Dependent Claim
27 words
a series of rollers disposable in supporting relation to the boat to be carried, and positioned to rollably support said boat upon the rails and cross members;
Claim 8
Dependent Claim
27 words
a series of rollers disposable in supporting relation to the boat to be carried, and positioned to rollably support said boat upon the rails and cross members;
Claim 9
Dependent Claim
97 words
a pair of legs pivotally attached to the respective rails at the other ends thereof for swinging movement between a collapsed position in which said legs underlie and extend alongside the respective rails to an extent sufficient for disposition of said other ends of the rails at ground level, and a rail-supporting position in which the legs extend vertically downwardly from the rails, the legs in the collapsed position thereof supporting the rails in a position of greater inclination from the horizontal than is assumed by the rails when the legs are in their rail-supporting positions; and
Claim 10
Dependent Claim
97 words
a pair of legs pivotally attached to the respective rails at the other ends thereof for swinging movement between a collapsed position in which said legs underlie and extend alongside the respective rails to an extent sufficient for disposition of said other ends of the rails at ground level, and a rail-supporting position in which the legs extend vertically downwardly from the rails, the legs in the collapsed position thereof supporting the rails in a position of greater inclination from the horizontal than is assumed by the rails when the legs are in their rail-supporting positions; and
Claim 11
Dependent Claim
98 words
resiliently contractile means detachably connectable between said rails and the respective legs and tensioned to bias the legs from their rail-supporting to their collapsed positions whenever the legs are shifted vertically upwardly out of contact with the ground surface while in the rail-supporting positions thereof, said rails being pivotable upwardly from said positions of lesser inclination thereof to free the legs from contact with the ground surface, said legs being free to gravitate to their rail-supporting positions when the resiliently contractile means is disconnected and the rails are pivotally moved upwardly from said positions of lesser inclination thereof.
