Abstract
Abstract A track-mounted trunk-type luggage-carrier body is longitudinally movable from its transporting position on the top of a station wagon (or van, panel-truck or like vehicle) to its loading position when pulled-down at the back of the vehicle. The tracks are C-shaped in cross-section and the carrier has a pair of wheels adjacent its front end guided therein. Tensioned coil springs may be used to pull the carrier body forwardly. Removable stop means normally prevent the wheels from leaving the rear track ends. Resilient bumpers on the bottom of the carrier prevent damage to the top and rear surfaces of the vehicle. Optionally, roller means can be attached to the vehicle surface adjacent the junction of its top and rear surface portions to protectively and easily guide the carrier body past the junction area.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A top-mounted pull-down luggage carrier for automotive vehicles, comprising: a pair of tracks adapted for parallel longitudinally disposed attachment to the top surface of a vehicle, a carrier body having a pair of low-friction means fixed thereto adjacent the front portion thereof and guidedly engaged with said tracks, cam-like means interacting between the under surface of said carrier body and adjacent top rear surfaces of said vehicle to protect said adjacent top rear vehicle surfaces as said carrier rests thereupon and/or is moved rearwardly and downwardly thereover while being continuously attached to and partially supported by said tracks, said cam-like means having a upwardly convex surface which is shaped first to lift said carrier body slightly as it moves upwardly and forwardly over said cam-like means and secondly to drop forwardly beyond a vertically disposed abutment for arresting rearward movement of said carrier body unless slightly lifted to clear said abutment.
Claim 2
Dependent Claim
151 words
A top-mounted pull-down luggage carrier for automotive vehicles, comprising: a pair of tracks adapted for parallel longitudinally disposed attachment to the top surface of a vehicle, a carrier body having a pair of low-friction means fixed thereto adjacent the front portion thereof and guidedly engaged with said tracks, cam-like means interacting between the under surface of said carrier body and adjacent top rear surfaces of said vehicle to protect said adjacent top rear vehicle surfaces as said carrier rests thereupon and/or is moved rearwardly and downwardly thereover while being continuously attached to and partially supported by said tracks, said cam-like means having a upwardly convex surface which is shaped first to lift said carrier body slightly as it moves upwardly and forwardly over said cam-like means and secondly to drop forwardly beyond a vertically disposed abutment for arresting rearward movement of said carrier body unless slightly lifted to clear said abutment.
