Abstract
Abstract A car top carrier is capable of both horizontal and vertical movement. The carrier has two telescoping tracks for horizontal movement. When the tracks are fully extended a finger in each track mechanically locks into place, thereby preventing any further horizontal movement. The carrier is vertically slidable by pulling a spring loaded plunger. Gravity allows the carrier to descend so that the load can be removed. The vertical descent is controlled by standard pneumatic or hydraulic cylinders. An electrical interlock between the engine ignition and the locked car top carrier prevents the load from sliding off the roof of the car due to centrifugal force.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
A roof top carrier apparatus having a horizontal telescoping track with means to mount the track on a roof of a vehicle, said horizontal track having plural relatively slidable segments, travel lock means mounted on the segments for relatively locking the segments in a telescopically closed position, extension locking means connected to the segments for locking the segments in extended position, and a cargo container mounted on one of the segments for moving from a centered position on a roof of a vehicle in which the travel locking means is locked to an extended position at a side of the vehicle at which extended position extension locking means are locked, said locking means comprising a pin extending through plural openings in first and second of the segments, a spring device, connected to the second of the segments and mounting the pin, whereby the third segment cams the spring device against spring pressure and withdraws the pin from the segment, whereby separation of the third segment from the spring device permits the spring device to move the pin into an opening in the first segment.
Claim 2
Dependent Claim
184 words
A roof top carrier apparatus having a horizontal telescoping track with means to mount the track on a roof of a vehicle, said horizontal track having plural relatively slidable segments, travel lock means mounted on the segments for relatively locking the segments in a telescopically closed position, extension locking means connected to the segments for locking the segments in extended position, and a cargo container mounted on one of the segments for moving from a centered position on a roof of a vehicle in which the travel locking means is locked to an extended position at a side of the vehicle at which extended position extension locking means are locked, said locking means comprising a pin extending through plural openings in first and second of the segments, a spring device, connected to the second of the segments and mounting the pin, whereby the third segment cams the spring device against spring pressure and withdraws the pin from the segment, whereby separation of the third segment from the spring device permits the spring device to move the pin into an opening in the first segment.
Claim 3
Dependent Claim
23 words
The cargo container apparatus of claim 1 wherein the travel locking means comprises a travel pin extending through aligned openings in the segments.
Claim 4
Dependent Claim
29 words
The cargo container apparatus of claim 2 wherein the travel pin comprises a spring loaded travel plunger having means for urging the plunger into the openings in the segments.
Claim 5
Dependent Claim
34 words
The cargo container apparatus of claim 1 wherein the extension lock means comprises a spring clip connected to one segment and an opening in a second of the segments for receiving the spring clip.
Claim 6
Dependent Claim
71 words
The cargo container apparatus of claim 1 further comprising a vertical track assembly connected to one of the segments of the horizontal track, the vertical track assembly having plural vertical track segments, a cargo bin connected to one of the vertical track segments and vertical track locking means connected to the vertical track segments for locking the vertical track segments against relative movement in an upward position of the cargo bin.
Claim 7
Dependent Claim
37 words
The cargo container apparatus of claim 5 wherein the vertical track locking means comprises a spring loaded plunger mounted on one other vertical track segment for engaging an opening in said one of the vertical track segments.
