Abstract
Abstract An automobile trunk loading apparatus for loading wheelchairs, outboard motors and the like into the trunk of an automobile comprises a carrier frame on which the object to be located may be removably attached. The frame is connected at the end which is to extend into the interior of the trunk to a pair of chain-like track elements which are constructed of interconnected oppositely facing U-shaped channel links having engaging surfaces to limit the radius of curvature attainable by the chain in the direction extending upwardly from the trunk floor to a minimum radius and to limit the radius of curvature on the opposite side thereof to approximately a straight line. When an object is located in the trunk in a loaded position, the chain-like track elements lie flat on the floor of the trunk. To remove an object, the frame nearest the edge of the trunk is lifted up sufficiently to clear the trunk and then pulled horizontally out of the trunk. The chain-like track members roll up link by link and then straighten out to lift the opposite end of the frame upwardly out of the trunk. When the end of the frame to which the track elements are connected clears the edge of the trunk, the free end is lowered to the ground and the object carried by the frame may be removed from it. To load the trunk, the procedure is reversed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
An automobile trunk loading apparatus including in combination: frame means having first and second ends for supporting an object to be loaded into an automobile trunk; at least one chain-like linkage means extendible to a substantially straight line configuration and comprised of a plurality of pivotally attached interconnected links including mutual engaging portions to limit the minimum radius of curvature attainable by said linkage means to a predetermined amount; means pivotally attaching one end of said linkage means to a first end of said frame means; and means for attaching the other end of said means adjacent the linkage interior of the trunk opening near the rear edge thereof to permit said linkage means to extend therefrom and lie on the bottom of the trunk to cause the first end of said frame means to be located in the interior of the trunk remote from the rear edge thereof and to cause the second end of said frame means to be located near the rear edge of the trunk when said apparatus is in the trunk in the loaded position.
Claim 2
Dependent Claim
180 words
An automobile trunk loading apparatus including in combination: frame means having first and second ends for supporting an object to be loaded into an automobile trunk; at least one chain-like linkage means extendible to a substantially straight line configuration and comprised of a plurality of pivotally attached interconnected links including mutual engaging portions to limit the minimum radius of curvature attainable by said linkage means to a predetermined amount; means pivotally attaching one end of said linkage means to a first end of said frame means; and means for attaching the other end of said means adjacent the linkage interior of the trunk opening near the rear edge thereof to permit said linkage means to extend therefrom and lie on the bottom of the trunk to cause the first end of said frame means to be located in the interior of the trunk remote from the rear edge thereof and to cause the second end of said frame means to be located near the rear edge of the trunk when said apparatus is in the trunk in the loaded position.
Claim 3
Dependent Claim
53 words
The combination according to claim 1 wherein said chain-like linkage means includes first and second chain-like linkage spaced apart from one another for attachment by said attaching means at said one and said other ends, respectively, to said first end of said frame means and the trunk opening near the rear edge thereof.
Claim 4
Dependent Claim
19 words
The combination according to claim 1 further including a handle attached to the second end of said frame means.
Claim 5
Dependent Claim
32 words
The combination according to claim 3 wherein said handle comprises a supplementary frame means pivotally attached to the second end of said frame means to accommodate objects of different sizes and shapes.
Claim 6
Dependent Claim
17 words
The combination according to claim 4 further including securing means for securing objects to said frame means.
Claim 7
Dependent Claim
61 words
The combination according to claim 1 wherein said interconnected links are further constructed with additional mutual engaging portions to limit the radius of curvature attainable by said linkage means on the side adjacent the floor of the trunk to a raidus which is substantially greater than the minimum radius of curvature attainable by said linkage means on the opposite side thereof.
Claim 8
Dependent Claim
149 words
The combination according to claim 6 wherein said linkage means is comprised of alternating, elongated, channel-shaped links of first and second types, each having a substantially U-shaped cross-section with the distance between the outside edges of said first links being less than the distance between the inside edges of said second links, said links being pivotally interconnected together in an alternating inverted relationship with the first links extending inside the second links to which they are pivotally connected, said first links having extensions on the edges thereof underlying the closed surface of the second links to establish the minimum radius of curvature of said linkage on the side adjacent the floor of the trunk, and the edge of the closed surface of said second link engaging the edges of said adjacent first links to establish the minimum radius of curvature attainable by said linkage on the opposite side thereof.
Claim 9
Dependent Claim
19 words
The combination according to claim 7 further including a handle attached to the second end of said frame means.
Claim 10
Dependent Claim
32 words
The combination according to claim 8 wherein said handle comprises a supplementary frame means pivotally attached to the second end of said frame means to accommodate objects of different sizes and shapes.
Claim 11
Dependent Claim
17 words
The combination according to claim 9 further including securing means for securing objects to said frame means.
