Abstract

Abstract A car top boat loader including a pair of parallel spaced guide rails terminating at a stationary rest at one end of the rails. The rails are pivotally supported on the car top in such a manner that the stationary rest extends over either the hood or trunk of the car. A carriage for supporting the boat to be loaded is movable supported by the spaced guide rails and is free to move through the length of the guide rails. The boat may be easily loaded to a balanced position on the carriage by pivoting the guide rails into engagement with the hood or trunk of the car after which the boat may be sequentially rested on the carriage and moved away from the stationary rest and then pivoted on the stationary rest permitting the carriage to return to the stationary rest until the boat is balanced on the carriage. Thereafter, the boat and supporting carriage are moved up the guide rails to a point at which the guide rails pivot to a horizontal balanced position on the car top. A first locking pin is provided for maintaining the guide rails in a horizontal position and a second locking pin locks the carriage to the guide rails for transporting the boat.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 231 words
A car top boat loader and boat carrying apparatus comprising: a carriage frame having a pair of spaced-parallel guide rails including in-turned horizontal roller flanges on the lower edges thereof and transverse supporting members rigidly innerconnecting the guide rails, a carriage for supporting the boat having side supports including a plurality of carriage rollers in engagement with the roller flanges and cross supports innerconnecting the side supports whereby the carriage may move longitudinally along the carriage frame, and means disposed intermediate the ends of the carriage frame for pivotally securing the carriage frame to the top of the car in a position with the stationary rest extending over either the hood or trunk of the car whereby, during loading, the boat may be easily moved to a balanced position on both the carriage and the car by pivoting the end of the carriage frame including the stationary rest into engagement with the hood or trunk of the car after which the boat may be sequentially rested on the carriage and moved away from the stationary rest and then pivoted on the stationary rest permitting the carriage to return to the stationary rest until the boat is balanced on the carriage after which the boat and supporting carriage are moved up the carriage frame to a point at which the carriage frame pivots to a horizontal balanced position on the car top.
Claim 2
Dependent Claim 231 words
A car top boat loader and boat carrying apparatus comprising: a carriage frame having a pair of spaced-parallel guide rails including in-turned horizontal roller flanges on the lower edges thereof and transverse supporting members rigidly innerconnecting the guide rails, a carriage for supporting the boat having side supports including a plurality of carriage rollers in engagement with the roller flanges and cross supports innerconnecting the side supports whereby the carriage may move longitudinally along the carriage frame, and means disposed intermediate the ends of the carriage frame for pivotally securing the carriage frame to the top of the car in a position with the stationary rest extending over either the hood or trunk of the car whereby, during loading, the boat may be easily moved to a balanced position on both the carriage and the car by pivoting the end of the carriage frame including the stationary rest into engagement with the hood or trunk of the car after which the boat may be sequentially rested on the carriage and moved away from the stationary rest and then pivoted on the stationary rest permitting the carriage to return to the stationary rest until the boat is balanced on the carriage after which the boat and supporting carriage are moved up the carriage frame to a point at which the carriage frame pivots to a horizontal balanced position on the car top.
Claim 3
Dependent Claim 53 words
The car top loader of claim 1 further including a plurality of apertures in one of the side rails of the carriage frame, a mating aperture in the corresponding side supporT of the carriage and a locking pin adapted to selectively interlock the guide rail and the side support in a balanced position.
Claim 4
Dependent Claim 266 words
A car top boat loader and carrying apparatus comprising: a carriage frame, a carriage secured to the carriage frame for longitudinal movement therealong, a stationary rest secured to the carriage frame at one end thereof, a pair of spaced-parallel carrying members disposed in engagement with the top of the car and extending transversely thereto and under the carriage frame, the member nearest the stationary rest pivotally securing the carriage frame to the top of the car at a pivot point positioned from the stationary rest approximately one-third of the total length of the carriage frame and supporting the carriage frame in a position with the stationary rest extending over either the hood or the trunk of the car and the carrying member furthest from the stationary rest including a pivot pin innerconnecting the carrying member and carriage frame to permit the carriage frame to pivot upon the top of the car, whereby, during loading, the boat may be easily moved to a balanced position on both the carriage and the car by pivoting the end of the carriage frame including the stationary rest into engagement with the hood or trunk of the car after which the boat may be sequentially rested on the carriage and moved away from the stationary rest and then pivoted on the stationary rest permitting the carriage to return to the stationary rest until the boat is balanced on the carriage after which the boat and supporting carriage are moved up the carriage frame to a point at which the carriage frame pivots to a horizontal balanced position on the car top.
Claim 5
Dependent Claim 266 words
A car top boat loader and carrying apparatus comprising: a carriage frame, a carriage secured to the carriage frame for longitudinal movement therealong, a stationary rest secured to the carriage frame at one end thereof, a pair of spaced-parallel carrying members disposed in engagement with the top of the car and extending transversely thereto and under the carriage frame, the member nearest the stationary rest pivotally securing the carriage frame to the top of the car at a pivot point positioned from the stationary rest approximately one-third of the total length of the carriage frame and supporting the carriage frame in a position with the stationary rest extending over either the hood or the trunk of the car and the carrying member furthest from the stationary rest including a pivot pin innerconnecting the carrying member and carriage frame to permit the carriage frame to pivot upon the top of the car, whereby, during loading, the boat may be easily moved to a balanced position on both the carriage and the car by pivoting the end of the carriage frame including the stationary rest into engagement with the hood or trunk of the car after which the boat may be sequentially rested on the carriage and moved away from the stationary rest and then pivoted on the stationary rest permitting the carriage to return to the stationary rest until the boat is balanced on the carriage after which the boat and supporting carriage are moved up the carriage frame to a point at which the carriage frame pivots to a horizontal balanced position on the car top.
