Abstract
Abstract Apparatus is disclosed for automatically loading and unloading a boat relative to the top of a camper vehicle. The apparatus provides a movable linkage mechanism adapted to be secured to the top of the vehicle. A pair of parallel arms connected to the gunwales of a boat is supported on the movable linkage mechanism. A spring means is provided for enabling the movable linkage mechanism to rotate the arms with the boat thereon in one direction, and a cable means is provided for enabling the movable linkage mechanism to rotate the arms with the boat thereon in the opposite direction. The movable linkage mechanism is effective in reducing the height of the swing of the boat being rotated through an arc of 180* between a rest position contingent to the ground in the back of the camper vehicle and an inverted rest position on the top of the vehicle, and is further effective in balancing the boat on the movable linkage mechanism during the swinging thereof such as to facilitate and minimize the power required to accomplish the movement.

Claim 1
Independent Claim
365 words
Apparatus for loading and unloading a boat on the top of a camper vehicle comprising: a pair of base members each adapted to be secured along a longitudinal side of the top of a camper vehicle; a pair of movable linkage mechanisms, each said mechanisms supported on a respective one of said base members and each said mechanisms including a linkage member capable of having a horizontally disposed position on said base member or an angularly disposed position in which it is leaning toward the rear of said vehicle; a pair of arms, each said arms supported on and slidably movable relative to a respective one of said linkage members and each said arms connected by pivots at one end thereof to the opposite sides of the stern of a boat and extending along the opposite gunwales of the boat; spring means acting to rotate said linkage members of said movable linkage mechanisms to their angularly disposed position to thereby rotate said arms and the boat connected thereto toward the rear of said vehicle; and cable means capable of being released to permit said spring means to act to rotate said linkage members to their angularly disposed position and capable of being taken up to overcome the action of said spring means for returning said linkage members to their horizontally disposed position on said base members; whereby when said cable means is released said spriNg means causes the linkage members of said movable linkage mechanisms to tilt upwardly thereby causing the arms with the boat resting thereon to be shifted rearwardly and downwardly relative to said linkage members to thereby lower the stern end of the boat and provide for the boat to be balanced on said movable linkage mechanisms to facilitate the further rotation of said arms and boat by said spring means to said angularly disposed position in which said boat is leaning toward the rear of said vehicle; and whereby when said cable means is taken up said movable linkage mechanisms including said linkage members are drawn to their horizontally disposed position on said base members in which said boat is held in an inverted position on the top of said vehicle.
Claim 2
Dependent Claim

Apparatus for loading and unloading a boat on the top of a camper vehicle comprising: a pair of base members each adapted to be secured along a longitudinal side of the top of a camper vehicle; a pair of movable linkage mechanisms, each said mechanisms supported on a respective one of said base members and each said mechanisms including a linkage member capable of having a horizontally disposed position on said base member or an angularly disposed position in which it is leaning toward the rear of said vehicle; a pair of arms, each said arms supported on and slidably movable relative to a respective one of said linkage members and each said arms connected by pivots at one end thereof to the opposite sides of the stern of a boat and extending along the opposite gunwales of the boat; spring means acting to rotate said linkage members of said movable linkage mechanisms to their angularly disposed position to thereby rotate said arms and the boat connected thereto toward the rear of said vehicle; and cable means capable of being released to permit said spring means to act to rotate said linkage members to their angularly disposed position and capable of being taken up to overcome the action of said spring means for returning said linkage members to their horizontally disposed position on said base members; whereby when said cable means is released said spriNg means causes the linkage members of said movable linkage mechanisms to tilt upwardly thereby causing the arms with the boat resting thereon to be shifted rearwardly and downwardly relative to said linkage members to thereby lower the stern end of the boat and provide for the boat to be balanced on said movable linkage mechanisms to facilitate the further rotation of said arms and boat by said spring means to said angularly disposed position in which said boat is leaning toward the rear of said vehicle; and whereby when said cable means is taken up said movable linkage mechanisms including said linkage members are drawn to their horizontally disposed position on said base members in which said boat is held in an inverted position on the top of said vehicle.
Claim 3
Dependent Claim
65 words
The invention is accordance with claim 1 wherein further release of said cable means provides for lowering said boat from its angularly disposed position adjacent said arms to a position contingent to the ground on the rear of the vehicle by rotating said boat about the pivots on the ends of said arms being held by the movable linkage mechanisms in said angularly disposed position.
Claim 4
Dependent Claim
55 words
The invention in accordance with claim 2 wherein taking up said cable means provides for raising said boat from its position contingent to the ground to said angularly disposed position by rotating said boat about the pivots on the ends of the arms being held by the movable linkage mechanisms in said angularly disposed position.
Claim 5
Dependent Claim
67 words
The invention in accordance with claim 1 including a longitudinally moving extension member supported on the rear portion of each said base member, said movable linkage mechanisms being connected to said extension members, and whereby said spring means provides for longitudinally moving said extension members and the movable linkage mechanisms with the arms of the boat thereon to a position extending beyond the rear of the vehicle.
Claim 6
Dependent Claim
104 words
The invention in accordance with claim 1 wherein each said movable linkage mechanism includes: a rear linkage member; a front linkage member; and an interconnecting linkage member; said front linkage member having front vertical legs pivotally connected to said base member and longitudinally movable relative thereto, said rear linkage member having rear vertical legs pivotally connected to said extension member, said rear linkage member and said interconnecting linkage member providing for positioning said rear linkage member, and said arm associated with each movable linkage mechanism being connected to rotate in accordance with and to be movable along the length of said rear linkage member.
Claim 7
Dependent Claim
94 words
The invention in accordance with claim 5 wherein each said base member is a channel structure provided with longitudinal slots along the front portion of the sidewalls thereof; wherein a cross rod is provided in said slots for pivotally connecting said vertical legs of said front linkage member to the base member; and wherein said spring means includes a pair of springs, each spring having one end attached to the top of the camper vehicle adjacent the rear end of one of the base members, and the other end connected to said cross rod.
Claim 8
Dependent Claim
31 words
The invention in accordance with claim 6 wherein each said rear linkage member is provided with roller means on which said arm rests for movement relative to said rear linkage member.
Claim 9
Dependent Claim
62 words
The invention in accordance with claim 1 including reel means; and a pulley attached to the free end of each of said arms; and wherein said cable means includes a pair of cables, each cable being connected to one side of the hull end of the boat and passing over the pulley on the end of said arm to said reel means.
Claim 10
Dependent Claim
57 words
The invention in accordance with claim 1 wherein the body of said boat is formed with an outer contour that conforms with the body of the vehicle and is so adapted to be positioned in its inverted position on the top of the vehicle that it gives the impression of being an extension of the roof thereof.
