Abstract
Abstract A folding support frame for boxes of pickup trucks which can be used for supporting a chain hoist or the like, and which will fold into a compact storage position on the top of the pickup box without having any members interfering with the box capacity. The support pivots to its operative position and has automatically raisable support linkages. The support frame can be moved longitudinally in direction along the box to place items held by a hoist into the pickup truck box.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
159 words
A support device for mounting onto the back of truck bodies and the like comprising a framework having spaced apart legs, spaced track means mounted on the rear portions of said truck body, separate slider members slidably mounted in each of said track means, means to pivotally mount said legs with respect to said slider members at spaced positions and support means for engaging said legs and holding said legs in a first predetermined angular position with respect to the truck body in a first direction of pivoting from a reference position comprising a folding linkage, means to mount said linkage to said slider members in relation to said pivotal mounting of said legs to position said folding linkage in proper relationship to support said legs when said legs are pivoted in said first direction, and means permitting said linkage to fold and not support said legs when said legs are pivoted in opposite direction from the first position.
Claim 2
Dependent Claim
159 words
A support device for mounting onto the back of truck bodies and the like comprising a framework having spaced apart legs, spaced track means mounted on the rear portions of said truck body, separate slider members slidably mounted in each of said track means, means to pivotally mount said legs with respect to said slider members at spaced positions and support means for engaging said legs and holding said legs in a first predetermined angular position with respect to the truck body in a first direction of pivoting from a reference position comprising a folding linkage, means to mount said linkage to said slider members in relation to said pivotal mounting of said legs to position said folding linkage in proper relationship to support said legs when said legs are pivoted in said first direction, and means permitting said linkage to fold and not support said legs when said legs are pivoted in opposite direction from the first position.
Claim 3
Dependent Claim
20 words
The combination as specified in claim 1 wherein said legs pivot in said opposite direction to substantially a horizontal position.
Claim 4
Dependent Claim
22 words
The combination as specified in claim 1 wherein said slider members are slidably mounted along opposite lateral sides of said truck body.
Claim 5
Dependent Claim
54 words
The combination as specified in claim 1 and flexible link means for controlling movement of said slider members along said track means, said flexible link means on opposite slider members being drivably mounted to a common shaft at the forward portions of the truck body for movement in opposite directions along said track means.
Claim 6
Dependent Claim
125 words
The combination as specified in claim 1 wherein said folding linkage comprises a separate first link for each leg pivotally mounted to the respective slider member, and spaced from the pivot of its respective leg, and positioned toward the rear of said truck body, a separate saddle member pivotally mounted to an opposite end of each of said first links, and aligned with its respective leg, and a separate control link pivotally mounted to each of said legs, and to its respective first link in the midportions thereof whereby said control links will cause said first links to move from a substantially upright leg supporting position with the legs in their first position to a folded position when said legs are pivoted in opposite direction.
Claim 7
Dependent Claim
35 words
The combination as specified in claim 5 wherein the pivotal connections between said first links and said control links are adjustable to change the position of the pivot of at least one of said links.
Claim 8
Dependent Claim
91 words
The combination as specified in claim 6 wherein said support frame includes a cross member joining said legs at the outer end thereof, and wherein said track means are of sufficient length so that said slider members can be moved on said track means to a position wherein said cross member will clear the rear extremity of said truck body, said slider members being movable toward the front of said truck body to a position wherein said cross member overlies the truck body when said legs are supported by said linkage.
