Bicycle rack for autos

Claim 2

An automobile bicycle rack for supporting at least one inverted bicycle with its seat removed from its tubular seat post, comprising a pair of bicycle support members having upper and lower ends, respectively, means for releasably securing the lower ends of said members in spaced relation on an exterior surface of an automotive vehicle with the upper ends of said members projecting outwardly from said surface in spaced relation; one of said members having in its upper end a socket for receiving and supporting the goose neck portion of an inverted bicycle, and the other of said members having on its upper end a cylindrical projection disposed to extend into the bore in the seat post of said inverted bicycle to assist in supporting the bicycle in an inverted position over said surface, when the goose neck portion of the bicycle is seated in said socket.

Claim 3

An automobile bicycle rack as defined in claim 1, wherein said other member has formed thereon between its lower end and said cylindrical projection an external circumferential shoulder engageable with the lower end of the seat post of an inverted bike to limit the extent to which said post slides downwardly over said projection.

Claim 4

An automobile bicycle rack as defined in claim 2, wherein said circumferential shoulder is truncated-conical in configuration, and is disposed coaxially of the axis of said cylindrical projection.

Claim 5

An automobile bicycle rack as defined in claim 1, including a flexible expander element secured to the upper end of said cylindrical projection and having an outer peripheral surface frictionally engageable with the bore wall of a seat post when the latter is inserted over said cylindrical projection.

Claim 6

An automobile bicycle rack as defined in claim 4, wherein said expander element has a cylindrical shank portion secured in a axial bore in said cylindrical projection, and has a tubular portion extending coaxially beyond said projection, an adjusting screw is threaded coaxially into said shank of said element and has thereon a circumferential shoulder engageable with the end of said tubular portion remote from said shank portion, and said tubular portion has therethrough a plurality of axially extending slots angularly spaced about the axis of said element and operative to cause the intervening sections of said annular wall of the element to expand radially outwardly when said screw is adjusted to draw the shoulder thereon axially toward the shank portion of the element.

Claim 7

An automobile bicycle rack as defined in claim 1, wherein the upper end of said one member has fixed thereon a gernally U-shaped retainer having the leg portions thereof extending parallel to one another in a horizontal plane, and in directions away from said other member, whereby the goose neck portion of an inverted bicycle is insertable onto the upper end of said one member to extend between the leg portions of said retainer to be secured thereby against lateral movement on said vehicle.

Claim 8

An automobile rack for supporting bicycles in inverted positions on an automotive vehicle, and with the seats removed from the tubular seat posts of the bicycle frames, comprising a plurality of pairs of bicycle supports each having a suction cup on its lower end for securing said lower end on the exterior surface of an automotive vehicle, a socket formed on the upper end of one of each of the two supports of a pair thereof, a cylindrical extension formed on the upper end of the other support of each pair thereof, means for securing said pairs of supports in spaced relation on said exterior surface of an automotive vehicle with said upper ends thereof projecting above said surface, and with the socket on said one support of each pair thereof being spaced from the cylindrical extension on the corresponding other support of said pair a distance approximately equal to the distance between the goose neck and seat post portions, respectively, of each bicycle frame that is to be supported on the rack, and means for releasably holding a bicycle in an inverted position on one of said pair of supports with the goose neck portion of the bike seated in the socket on said one support of the pair, and with the said cylindrical extension on said other support of the pair extending into the bore in the seat post of the bike frame.

Claim 9

An automobile rack for supporting bicycles in inverted positions on an automotive vehicle, and with the seats removed from the tubular seat posts of the bicycle frames, comprising a plurality of pairs of bicycle supports each having a suction cup on its lower end for securing said lower end on the exterior surface of an automotive vehicle, a socket formed on the upper end of one of each of the two supports of a pair thereof, a cylindrical extension formed on the upper end of the other support of each pair thereof, means for securing said pairs of supports in spaced relation on said exterior surface of an automotive vehicle with said upper ends thereof projecting above said surface, and with the socket on said one support of each pair thereof being spaced from the cylindrical extension on the corresponding other support of said pair a distance approximately equal to the distance between the goose neck and seat post portions, respectively, of each bicycle frame that is to be supported on the rack, and means for releasably holding a bicycle in an inverted position on one of said pair of supports with the goose neck portion of the bike seated in the socket on said one support of the pair, and with the said cylindrical extension on said other support of the pair extending into the bore in the seat post of the bike frame.

Claim 10

An automobile bicycle rack as defined in claim 7, wherein said securing means comprises a first plurality of elongate, parallel members secured to and extending between said pairs of supports to maintain said pairs of supports in spaced relation to each other, and a second plurality of elongate, parallel members secured to and extending between the two supports of each pair thereof, and transversely of said first plurality of members and operative to maintain the space between the two supports of a pair approximately equal to said distance between the goose neck and seat post portions of a bike, one of said pluralities of members being adjustable relative to the associated supports thereby to adjust the space maintained by said one plurality of members between the last-named supports.

Claim 11

An automobile bicycle rack as defined in claim 8, wherein said one plurality of members comprises a plurality of metal rods each of which is secured at one end to one support of each pair thereof for rotation relative to said one support and is adjustably secured at its opposite end to the other support of each pair thereof, whereby upon rotation of one of said rods said other support of a pair will be shifted toward or away from said one support of the pair thereby to adjust the distance between said pair of supports.

Claim 12

An automobile bicycle rack as defined in claim 9, wherein said members include a torsion bar extending between and interconnecting said one supports of said pairs, and said one ends of said rods are secured to said one supports of said pairs for limited pivotal movement relative to said one support to which it is secured, whereby each of said one supports is pivotal slightly relative to the axis of said torsion bar to allow slight adjustments in the distance separating the upper end of said one support of a pair from the upper end of the other support of the pair.
