Abstract
Abstract An inclinable pickup truck carriage together with a pair of demountable posts at the rear of the truck and a corresponding pair of tension lines can demount an attachment such as a camper from the truck. Each tension line runs from a point on the attachment, then over a sheave at the top of its post, and on to a point on the chassis. Between the sheave and the chassis, the tension line passes around pulleys located alternately on the side of the carriage and on the side of the chassis. The attachment can thus easily demount after the inclination of the carriage from a horizontal position, parallel to the truck chassis, into an inclined position, and after the insertion of supports between the attachment and the ground.

Claim 1
Independent Claim
288 words
In a truck having a chassis, a carriage pivotally mounted on the chassis, an attachment to the truck mounted on the carriage, and means for inclining the carriage between a horizontal position parallel to the chassis and an inclined position, an apparatus for demounting the attachment from the carriage, the apparatus comprising: a. a right and a left sheave disposed on the right and left side, respectively, of the truck; b. a right and a left carriage guide pulley on the right and left side, respectively, of the carriage forward of the carriage''s pivot; c. a right and a left chassis guide pulley on the right and the left side, respectively, of the chassis forward of the carriage''s pivot; d. a right tension line reeved successively over the right sheave, the right carriage guide pulley, and the right chassis guide pulley, and being connected at its rear end to the attachment at a point below the right sheave and at its forward end to the chassis; and e. a left tension line reeved successively over the left sheave, the left carriage guide pulley, and the left chassis guide pulley, and being connected at its rear end to the attachment at a point below the left sheave and at its forward end to the chassis; whereby inclining of the carriage effects lifting of the attachment at its front end by the carriage itself and at its rear end by a consequent shortening of the right and the left tension lines between their points of connection to the attachment and the corresponding sheaves so as to allow the attachment to be shifted between a position on the carriage and a position on supports interposed between the attachment and the ground.
Claim 2
Dependent Claim
288 words
In a truck having a chassis, a carriage pivotally mounted on the chassis, an attachment to the truck mounted on the carriage, and means for inclining the carriage between a horizontal position parallel to the chassis and an inclined position, an apparatus for demounting the attachment from the carriage, the apparatus comprising: a. a right and a left sheave disposed on the right and left side, respectively, of the truck; b. a right and a left carriage guide pulley on the right and left side, respectively, of the carriage forward of the carriage''s pivot; c. a right and a left chassis guide pulley on the right and the left side, respectively, of the chassis forward of the carriage''s pivot; d. a right tension line reeved successively over the right sheave, the right carriage guide pulley, and the right chassis guide pulley, and being connected at its rear end to the attachment at a point below the right sheave and at its forward end to the chassis; and e. a left tension line reeved successively over the left sheave, the left carriage guide pulley, and the left chassis guide pulley, and being connected at its rear end to the attachment at a point below the left sheave and at its forward end to the chassis; whereby inclining of the carriage effects lifting of the attachment at its front end by the carriage itself and at its rear end by a consequent shortening of the right and the left tension lines between their points of connection to the attachment and the corresponding sheaves so as to allow the attachment to be shifted between a position on the carriage and a position on supports interposed between the attachment and the ground.
