Light bag rack for a bicycle

A light bag rack (10) for a bicycle, wherein the bicycle includes a seat (12) supported on a seat post (14), the seat (12) including a first frame rail (16) and a second frame rail (18) secured to the post (14) wherein parallel portions of the first and second frame rails (16, 18) adjacent the seat post (14) are aligned about parallel to each other and extend in a direction parallel to a direction-of-travel axis of the bicycle, and wherein the parallel portions of the first and second frame rails (16, 18) define a first seat-frame distance (22) being a shortest distance between exterior edges (24, 26) of the frame rails (16, 18) forward of the seat post (14) in a direction (28) toward a front of the bicycle and the parallel portions of the first and second frame rails (16, 18) define a second seat-frame distance (32) being a shortest distance between interior edges (36, 34) of the frame rails (16, 18) rearward of the seat post (14) in a direction (30) toward a rear of the bicycle, the light bag rack (10) comprising:

• a. an approximately U-shaped frame (42) having a closed securing end (44), an opposed open mounting end (46), a first rod (48) and a second rod (50) extending between the closed securing end (44) and the open mounting end (46), and the first and second rods (48, 50) defining a pinch point (52) between the securing and mounting ends (44, 46);
• b. wherein the first and second rods (48, 50) define a first rack distance (54) being a shortest distance between interior edges (56, 58) of the first and second rods (48, 50) adjacent the securing end (44) so that the first rack distance (54) is greater than the first seat-frame distance (22);
• c. wherein the first and second rods (48, 50) define a second rack (60) distance being a shortest distance between exterior edges (64, 66) of the first and second rods (48, 50) at the pinch point (52) so that the second rack distance (60) is less than the second seat-frame distance (32);
• and,
• d. wherein the first and second rods (48, 50) of the rack (10) are sufficiently flexible so that the open mounting end (46) may expand around the exterior edges (24, 26) of the first and second seat frame rails (16, 18) forward of the seat post (14) and may compress between the first and second seat frame rails (16, 18) rearward of the seat post (14) whenever the securing end (44) of the rack (10) is positioned to contact the exterior edges (24, 26) of the first and second frame rails (16, 18) forward of the seat post (14) while the first and second rods (48, 50) adjacent the pinch point (52) of the rack (10) contact the interior edges (34, 36) of the first and second frame rails (48, 50) to secure the rack (10) to the first and second frame rails (16, 18) of the seat (12).
