Abstract
A space frame for an automotive vehicle includes a plurality of structural members and joint constructions for joining the structural members together such that the outer surfaces of the structural members are substantially flush with each other.
Claims15
A space frame for an automotive vehicle, comprising:
- a plurality of structural members having outer surfaces;
- and
- joint means axially spacing said structural members for joining said structural members together such that said outer surfaces of said structural members are flush with each other, said joint means comprising a connector having a generally rectangular shaped channel adapted to receive one of said structural members and a generally rectangular shaped extension adapted to be disposed into another of said structural members, said connector having a first outer surface and said extension having a second outer surface offset inwardly a predetermined amount relative to said first outer surface, said connector including engagement means engaging one of said structural members for flexing outwardly and returning to its original position to snap-fit onto the one of said structural member such that said outer surfaces of said structural members are flush with said first outer surface.
A space frame as set forth in calm 1 wherein said joint means further comprises means forming a pair of grooves on opposed sides of the one of said structural members, and said engagement means comprises a pair of opposed tabs on opposed sides of said connector adjacent said channel, said tabs adapted to be disposed in said grooves.
A space frame for an automotive vehicle, comprising:
- at least one longitudinally extending structural member;
- at least one vertically extending structural member;
- and
- joint means for joining said longitudinally and vertically extending structural members together such that outer surfaces of said longitudinally and vertically extending structural members are flush with each other, said vertically extending structural member comprising a first extrusion having a first outer surface and a generally rectangular shaped first open end, said longitudinally extending structural member comprising a second extrusion having a second outer surface and a generally rectangular shape, said joint means comprising a connector including means forming a generally rectangular shaped channel adapted to receive said second extrusion and a generally rectangular shaped extension adapted to be disposed through said first open end of said first extrusion, said joint means including means forming a pair of grooves on opposed sides of said second extrusion and engagement means engaging said second extrusion for flexing said channel forming means outwardly and returning to its original position to snap-fit into said grooves, said connector having a third outer surface and said extension being offset inwardly such that said first outer surface is flush with said third outer surface and said second extrusion having a portion offset inwardly such that said third outer surface is flush with said second outer surface.

A space frame for an automotive vehicle, comprising:
- at least one longitudinally extending first extrusion;
- at least one vertically extending second extrusion;
- a connector having a pair of spaced side walls forming a generally rectangular shaped channel adapted to receive said first extrusion and a generally rectangular shaped extension adapted to be disposed through an open end of said second extrusion for joining said first and second extrusions together such that outer surfaces of said first and second extrusions are flush with each other;
- said first extrusion including means forming a pair of grooves on opposed sides thereof;
- said side walls having a tab at each end thereof extending across said channel to form an open end having a width less than a width of said channel, said tab engaging said first extrusion to flex said side wall outwardly and to return to its original position when disposed in said groove;
- said side walls having an outer surface and said extension being offset inwardly such that an outer surface of said second extrusion is flush with said outer surface of said side walls and said first extrusion has a portion offset inwardly such that said outer surface of said side walls is flush with an outer surface of said first extrusion.

A space frame for an automotive vehicle, comprising:
- at least one longitudinally extending first extrusion;
- at least one vertically extending second extrusion;
- an extruded connector having a base wall interconnecting a pair of spaced side walls forming a generally rectangular shaped and longitudinally extending channel adapted to receive said first extrusion and an inverted generally U-shaped extension connected to said base wall and to form an aperture extending longitudinally therethrough, said extension being adapted to be disposed through an open end of said second extrusion for joining said first and second extrusions together such that outer surfaces of said first and second extrusions are flush with each other;
- said first extrusion including means forming a pair of inclined grooves on opposed sides thereof;
- said side walls having an inclined tab at each end thereof to form an open end having a width less than a width of said channel, said tab engaging said first extrusion to flex said side wall outwardly and to return to its original position when disposed in said groove;
- said side walls having an outer surface and said extension being offset inwardly such that an outer surface of said second extrusion is flush with said outer surface of said side walls and said first extrusion has a portion offset inwardly such that said outer surface of said side walls is flush with an outer surface of said first extrusion.
