BACKGROUND
The present disclosure relates to multi-seat juvenile strollers. In particular, the present disclosure relates to a stroller including a first seat and a second seat that is used after removal of the first seat.
SUMMARY
A multi-seat juvenile stroller in accordance with the present disclosure includes a first seat, second seat, and a rolling stroller frame. The first seat includes a removable child-support sling and the second seat includes a mobile infant carrier. The removable child-support sling is used for movement with the rolling stroller frame and can be removed by a user. Once the child-support sling is removed, the mobile infant carrier can be installed on the stroller and used infants.
In illustrative embodiments, a sling mount is coupled to a mount-support bar on the stroller frame. The sling mount is configured to couple temporarily the removable child-support sling to the stroller frame in a first-seat space through the use of a fastener. Upon removal of the child-support sling, the second seat can be mounted onto the frame in the first-seat space using a second-seat mount means.
In illustrative embodiments, the sling mount includes a first side web coupled to a first rail of the mount-support bar, a second side web coupled to a second rail of the mount-support bar, and a lower web coupled to a center rail of the mount-support bar. The removable child-support sling is arranged to lie in a space defined by the first side, second side, and lower webs.
In illustrative embodiments, the fastener includes a first and second side means for temporarily coupling first side, second side, and lower web of the sling mount to the removable child-support sling. The first and second side means of the fastener include an inside zipper track coupled to the removable child-support sling and an outside zipper track coupled to the sling mount. The outside zipper track is configured to mate with inside zipper track using at least one sliding piece.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION
A multi-seat juvenile stroller 10 in accordance with the present disclosure includes a rolling stroller frame 12, a forward-facing first seat 14, and a rearward-facing second seat 16 as suggested in FIG. 1. Forward-facing first seat 14 is coupled to rolling stroller frame 12 as suggested in FIG. 2 to establish a first seating mode of stroller 10. Alternatively, rearward-facing second seat 16 can be mounted on a second-seat mount 17 coupled to rolling stroller frame 12 as suggested in FIG. 3 to establish a second seating mode of stroller 10. Illustrations of components and component installation techniques associated with first seat 14 are provided in FIGS. 4-7.
Rolling stroller frame 12 includes a base 18, wheels 20 coupled to base 18, and a mount-support bar 22 coupled to base 18 as shown, for example, in FIGS. 1 and 4. First seat 14 is coupled to mount-support bar 22 in an illustrative manner shown in FIG. 1 to produce the stroller shown in FIG. 2. Second seat 16 is coupled to mount-support bar 22 in an illustrative manner also shown in FIG. 1 to produce the stroller shown in FIG. 3.
As suggested in FIG. 4, first seat 14 includes a sling mount 24 and a removable child-support sling 26. Sling mount 24 is configured to be coupled to mount-support bar 22 of frame 12 and remain in that mounted position in both of the first-seat mode shown in FIG. 2 and the second-seat mode shown in FIG. 3.
First seat 14 further includes a fastener 28 (e.g., a zipper) configured to couple temporarily removable child-support sling 26 to sling mount 24 as suggested in FIG. 1 to hold removable child-support sling 26 in a first-seat space 29 defined by mount-support bar 22 of frame 12 for movement with rolling stroller frame 12 as shown in FIG. 2. Child-support sling 26 remains coupled to sling mount 24 as suggested in FIG. 2 as long as a caregiver desires to configure stroller 10 for use in the first eating mode. Child-support sling 26 later can be separated from sling mount 24 by unfastening fastener 28 to expose or otherwise empty first-seat space 29 bounded, in part, by sling mount 24 so as to allow the caregiver to reconfigure stroller 10 for use in the second seating mode as suggested in FIGS. 1 and 3.
In an illustrative embodiment, second seat 16 includes an infant carrier 34 and first and second carrier mounts 31, 32 as shown, for example, in FIG. 1. First and second carrier mounts 31, 32 cooperate to define a carrier support 30. Carrier support 30 is configured to mate with second-seat mount 17 coupled to rolling stroller frame 12 to support infant carrier 34 in a mounted position on stroller frame 12 (after removal of first seat 14) as suggested in FIGS. 1 and 3.
In the embodiment of FIGS. 1-7, second-seat mount 17 includes a first mount anchor 51 coupled to rolling stroller frame 12. Second-seat mount 17 also includes a second mount anchor 52 coupled to rolling stroller frame 12 and arranged to lie in spaced-apart relation to first mount anchor 51 as suggested in FIG. 1. First and second mount anchors 51, 52 are located above U-shaped sling mount 24 included in first seat 14 and coupled to mount-support bar 22 of stroller frame 12 as suggested in FIG. 1. Mount-support bar 22 is arranged to lie between first and second mount anchors 51, 52 and a U-shaped support bar 76 coupled to mount-support bar 22 and included in rolling stroller frame 12 as suggested in FIG. 4.
Infant carrier 34 includes a shell 36 configured to receive an infant therein, a carry handle 38 coupled to shell 36, and first and second mount receivers 41, 42 coupled to shell 36 as suggested in FIG. 1. It is within the scope of this disclosure to configure infant carrier 34 so that it can be used to transport infants when not mounted on rolling stroller frame 12.
First carrier mount 31 is configured to be coupled to first mount anchor 51 provided at a first site 61 on mount-support bar 22 (using any suitable means) and second carrier mount 32 is configured to be coupled to second mount anchor 52 provided at a second site 62 on mount-support bar 22 (using any suitable means) as suggested in FIG. 1. Such couplings do not interfere with or disrupt the U-shaped sling mount 24 that is coupled to remain with mount-support bar 22 owing to the fact that first and second mount anchors 51, 52 are located above sling mount 24 as shown best in FIG. 1.
As suggested in FIG. 1, in an illustrative embodiment, each of first and second mount carriers 31, 32 includes a horizontal member 33 and a vertical member 35. Horizontal member 33 of first carrier mount 31 includes an outer end 37 adapted to be coupled to first mount anchor 51 at site 61 and an opposite inner end 39. Horizontal member 33 of second carrier mount includes an outer end 37 adapted to be coupled to second mount anchor 52 at site 62 and an opposite inner end 39. Vertical member 35 of first carrier mount 31 is arranged to extend upwardly from inner end 39 of companion horizontal member 33 and mate with first mount receiver 41 of infant carrier 34. Vertical member 35 of second carrier mount 32 is arranged to extend upwardly from inner end 39 of companion horizontal member 33 and mate with second mount receiver 42 of infant carrier 34.
To establish the second seating mode of stroller 10 using rolling stroller frame 12 and second seat 16, first carrier mount 3 of second seat 16 is mated with first mount anchor 51 of second-seat mount 17 and second carrier mount 32 of second seat 16 is mated with second mount anchor 52 of second-seat mount 17 as suggested in FIG. 1. Then, shell 36 of infant carrier 34 is lowered into empty first-seat space 29 bounded, in part, by U-shaped sling mount 24 to position (1) first mount receiver 41 of infant carrier 34 in close proximity to the underlying first carrier mount 31 and (2) second mount receiver 42 of infant carrier 34 in close proximity to the underlying second carrier mount 32.
