As best shown in FIGS. 7, 8 and 11, in one embodiment the linkage assembly 38 connects the first side frame assembly 34 to the second side frame assembly 36, and provides rigidity to the bicycle trailer in both the open and closed configurations, but also allows the bicycle trailer 10 to be collapsed or folded such that the first side frame assembly 34 and second side frame assembly 36 are adjacent one another (see FIG. 11). In one embodiment, the linkage assembly 38 is connected to the first side frame assembly 34 and the second side frame assembly 36 toward the rear 64 of the frame 30, and the linkage assembly 38 is not directly connected to the frame 30 adjacent a front 62 of the frame 30. The linkage assembly 38 preferably pivotally connects the first side frame assembly 34 to the second side frame assembly 36 in both the open configuration and the folded configuration. In one embodiment, the linkage assembly 38 comprises a first linkage 100 and a second linkage 106. Further, in one embodiment the linkage assembly 38 is positioned below the floor assemblies 40, 42 in the open configuration and in the folded configuration of the frame 30. The first linkage 100 has a first end 102 and a second end 104. The first end 102 of the first linkage 100 is pivotally connected to the first side frame assembly 34. The second linkage 106 has a first end 108 and a second end 110. The first end 108 of the second linkage 106 is pivotally connected to the second side frame assembly 36. Additionally, the first linkage 100 is pivotally connected to the second linkage 106. In one embodiment, the linkage assembly 38 is preferably v-shaped.

In one embodiment, the first end 102 of the first linkage 100 has an outer housing 103 that fits around the first side frame assembly 34 to pivotally secure the first linkage 100 to the first side frame assembly 34. In a preferred embodiment, the outer housing 103 at the first end 102 of the first linkage 100 may be a tubular member that is pivotally fitted around the first rear frame member 46 of the first side frame assembly 34, possibly with bushings and/or bearings therebetween to provide for easier rotation/pivoting of the first linkage 100 about the first side frame assembly 34. Similarly, the first end 108 of the second linkage 106 has an opening with an outer housing 103 that fits around the second side frame assembly 36 to pivotally secure the second linkage 106 to the second side frame assembly 36. In a preferred embodiment, the outer housing 103 at the first end 108 of the second linkage 106 may be a tubular member that is pivotally fitted around the second rear frame member 54 of the second side frame assembly 36, possibly with bushings and/or bearings therebetween to provide for easier rotation/pivoting of the second linkage 106 about the second side frame assembly 36. Preferably, the outer housing 103, which in a preferred embodiment, is a generally tubular or cylindrical structure, has an extended length to provide additional rigidity to the frame assembly 30 of the bicycle trailer 10.

Further, in one embodiment the second end 104 of the first linkage 100 is pivotally connected to the second end 110 of the second linkage 106. In one embodiment, the pivot connection 118 between the first linkage 100 and the second linkage 106 is that of a clevis and tang orientation. For example, one of second end 104 of the first linkage 100 or the second end 110 of the second linkage 106 has a clevis 120, and the other of the second end 104 of the first linkage 100 or the second end 110 of the second linkage 106 has a tang 122 that fits within the clevis 120. A pin 124 joins the clevis 120 and tang 122, and allows the first linkage 100 and the second linkage 106 to pivot with respect to one another during opening and closing of the bicycle trailer 10. The first linkage 100 and the second linkage 106 form a two-bar linkage to assist in keeping the first side frame assembly 34 secured to the second side frame assembly 36 in both the open configuration and the folded configuration, as well as in the transition between the open and folded configuration. The linkage assembly 38 generally moves in a second plane to transition from the open configuration shown in FIG. 9 to the folded configuration shown in FIG. 11. With reference to the plane of movement of the floor assembly, which moves in the first plane, the second plane of movement of the linkage assembly 38 is generally perpendicular to the first plane of movement of the floor assembly. Put another way, the floor assembly moves in a first plane, the linkage assembly moves in a second plane, and the first and second planes are perpendicular.

Further, as shown in FIGS. 7 and 8, in one embodiment the linkage assembly 38 may have one or more central clamp members or receivers 136 that engages one of the central support members 74, 86 of the floor assembly 20 to retain the first and second floor assemblies 40, 42 in the lower position until a sufficient force is applied to lift the floor assemblies 40, 42 and disengage the central support members 74, 86 from the respective receiver 136. Accordingly, the receiver 136 extends from the linkage assembly 38 and releasably engages the floor assembly. A tab (not shown), such as a fabric pull tab, may be connected to the receivers 136 from the central support members 74, 86 to allow a user to pull the central support members out of engagement with the receivers 136 to allow for folding of the bicycle trailer 10. In one embodiment, a force of at least 10 lbs. is required to disengage the central support members 74, 86 from the receivers 136. In that manner the floor assemblies 40, 42 should not become unintentionally disengaged from the receivers 136 and the bicycle trailer 10 will remain in the opened configuration unless intentionally manipulated to set it in motion to convert to the folded configuration. In one embodiment, the floor assembly and the linkage assembly pivot between the first side frame assembly and the second side frame assembly to move the first and second side frame assemblies closer to one another in the folded position as shown in FIG. 11.
