Abstract

Abstract An improved car top carrier designed particularly for carrying boats and which allows a single person to both load and unload the boat unassisted while providing secure transportation for the boat. It comprises basically a three point support system including a generally triangular support at the front of the vehicle, for example mounted on the front bumper with an apex at the top, which constitutes a pivot point for both the loading and unloading of the boat. The second two points of support are provided by a cross bar support secured to the top of the vehicle whereby opposite gunwales of the boat are supported and may be secured to the cross bar support. In one embodiment, the cross bar support is a box for carrying long objects such as fishing rods.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 166 words
A vehicle top boat carrier comprising: a first support assembly adapted to be secured to the front of a vehicle including a single point support member having a pivotal securing means at a level corresponding approximately with the top of the vehicle; a pair of support members securable to the vehicle at a distance rear of the first support, extending upward to at least the level of the top of the vehicle and laterally spaced to engage and support the gunwales of a boat; whereby a pointed prow boat may be carried on said vehicle with the bow region secured to said front support at the pivotal attachment, and the gunwale portions providing three point support for the boat; wherein said pivotal securing means includes pivot means installable in an upward direction to provide pivoting of the boat thereabout during loading and unloading thereof and said securing means is reversible with the boat in place to provide a positive lock for the bow of the boat.
Claim 2
Dependent Claim 166 words
A vehicle top boat carrier comprising: a first support assembly adapted to be secured to the front of a vehicle including a single point support member having a pivotal securing means at a level corresponding approximately with the top of the vehicle; a pair of support members securable to the vehicle at a distance rear of the first support, extending upward to at least the level of the top of the vehicle and laterally spaced to engage and support the gunwales of a boat; whereby a pointed prow boat may be carried on said vehicle with the bow region secured to said front support at the pivotal attachment, and the gunwale portions providing three point support for the boat; wherein said pivotal securing means includes pivot means installable in an upward direction to provide pivoting of the boat thereabout during loading and unloading thereof and said securing means is reversible with the boat in place to provide a positive lock for the bow of the boat.
Claim 3
Dependent Claim 33 words
The combination in accordance with claim 1 wherein said pivotal securing means comprises an upward extending tapered pin when it is in the loading condition and reversible to provide and upward extending bolt.
Claim 4
Dependent Claim 273 words
A vehicle top boat carrier comprising: a first support assembly adapted to be secured to the front bumper region of a vehicle including a first rigid support member extending substantially vertically and free of overhang of the vehicle hood region and having an upwardly extending pivotal sibgle point securing means into which the prow of a boat may be lowered at a level corresponding approximately with the top of the vehicle and without the boat overhanging substantially any portion of the vehicle when the boat extends in front of the vehicle; a second support member securable to the vehicle at a distance rear of the first support member, and laterally extending to engage and support the gunwales of a boat when a boat is positioned with its prow on the said uupwardly extending single point pivotal securing means of said first support assembly; whereby a pointed prow boat may be loaded on said vehicle by lifting the bow of the boat and lowering the bow onto said upward extending single point pivotal securing means, pivoted, and the stern of the boat lifted to rest on said second support member and said boat may be carried on said vehicle with said bow region secured to said first support assembly at said upwardly extending single point pivotal securing means, and the gunwale portions by said second laterally extending support member thereby providing three point support for the boat; including securing means at said first support assembly convertible from a pivotal support device to a securing device; wherein such securing means comprises a socket for receiving a ball and locking means adapted to receive said ball.
Claim 5
Dependent Claim 273 words
A vehicle top boat carrier comprising: a first support assembly adapted to be secured to the front bumper region of a vehicle including a first rigid support member extending substantially vertically and free of overhang of the vehicle hood region and having an upwardly extending pivotal sibgle point securing means into which the prow of a boat may be lowered at a level corresponding approximately with the top of the vehicle and without the boat overhanging substantially any portion of the vehicle when the boat extends in front of the vehicle; a second support member securable to the vehicle at a distance rear of the first support member, and laterally extending to engage and support the gunwales of a boat when a boat is positioned with its prow on the said uupwardly extending single point pivotal securing means of said first support assembly; whereby a pointed prow boat may be loaded on said vehicle by lifting the bow of the boat and lowering the bow onto said upward extending single point pivotal securing means, pivoted, and the stern of the boat lifted to rest on said second support member and said boat may be carried on said vehicle with said bow region secured to said first support assembly at said upwardly extending single point pivotal securing means, and the gunwale portions by said second laterally extending support member thereby providing three point support for the boat; including securing means at said first support assembly convertible from a pivotal support device to a securing device; wherein such securing means comprises a socket for receiving a ball and locking means adapted to receive said ball.
Claim 6
Dependent Claim 28 words
The combination in accordance with claim 3 wherein said locking means comprises a pin extending through the wall of said socket to hold said ball within said socket.
Claim 7
Dependent Claim 276 words
A vehicle top boat carrier comprising: a first support assembly adapted to be secured to the front bumper region of a vehicle including a first rigid support member extending substantially vertically and free of overhang of the vehicle hood region and having an upwardly extending pivotal single point securing means into which the prow of a boat may be lowered at a level corresponding approximately with the top of the vehicle and without the boat overhanging substantially any portion of the vehicle when the boat extends in front of the vehicle; a second support member securable to the vehicle at a distance rear of the first support member, and laterally extending to engage and support the gunwales of a boat when a boat is positioned with its prow on the said upwardly extending single point pivotal securing means of said first support assembly; whereby a pointed prow boat may be loaded on said vehicle by lifting the bow of the boat and lowering the bow onto said upward extending single point pivotal securing means, pivoted and the stern of the boat lifted to rest on said second support member and said boat may be carried on said vehicle with said bow region secured to said first support assembly at said upwardly extending single point pivotal securing means, and the gunwale portions by said second laterally extending support member thereby providing three point support for the boat; wherein said cross member comprises an elongated box extending transverse to the length of said vehicle; said box including an access door for the interior of said box means for securing a boat to said box from the interior thereof.
