Abstract

The disclosure relates to a stroller comprising a lower frame. The lower frame comprises a front frame section connected to a rear frame section. The rear frame section comprises a rear wheel assembly extending between two rear frame members. The rear wheel assembly is pivotally connected to both rear frame members and having ground engaging rear wheels attached thereto and is movable under the rear frame section between a first load bearing position wherein the rear wheels are retained forward of the pivotal connection and a second position wherein the rear wheels are rearward of the pivotal connection.

Claims

1 . A stroller comprising a lower frame, the lower frame comprising: a front frame section connected to a rear frame section, wherein the rear frame section comprises a rear wheel assembly extending between two rear frame members; wherein the rear wheel assembly is pivotally connected to both rear frame members and having rear wheels attached thereto; the rear wheel assembly movable under the rear frame section between a first load bearing position wherein the rear wheels are retained forward of the pivotal connection and a second position wherein the rear wheels are rearward of the pivotal connection.

2. The stroller of claim 1 wherein in the first load bearing position the rear wheel assembly receives the rear frame members in respective recesses defined therein such that each recess is urged against each rear frame member under load.

3. The stroller of claim 1 or claim 2, wherein in the first load bearing position, the recesses of the rear wheel assembly are channels dimensioned to receive therein a corresponding rear frame member.

4. The stroller of any one the preceding claims, wherein in the first load bearing position the rear wheel assembly is releasably retained in said position by a latching mechanism.

5. The stroller of any one the preceding claims, wherein a tab of each rear frame member includes an aperture for receiving a pivot member engageable with the rear wheel assembly for pivotal connection thereof.

6. The stroller of any one the preceding claims, wherein the rear wheel assembly includes apertures for releasably securing axles of the rear wheels attached thereto.

7. The stroller of any one the preceding claims, wherein the rear wheel assembly includes a void on each side on the upper surface in the second position for receiving corresponding projections therein.

8. The stroller of any one the preceding claims, wherein the voids are configured to receive projections of a seat frame, carrycot, car seat or a basket.

9. The stroller of any one the preceding claims, wherein the rear wheel assembly includes a web spanning between the rear frame members dimensioned for supporting feet of a child thereupon in at least the second position.

10. The stroller of any one the preceding claims wherein the rear wheel assembly is positioned under a bar extending between the rear frame members in a first position.

11 . The stroller of any one the preceding claims, wherein the rear wheel assembly includes a brake paddle actuable in either the first position or the second position to engage and disengage a sliding member from engagement with corresponding apertures defined in hubs of the wheels.

12. The stroller of any one of the preceding claims wherein the rear wheel assembly has a face configured to bear against a complementary face on the rear frame assembly in the second load bearing position so as to transfer load applied thereto onto the suspension assembly.

13. The stroller of any one the preceding claims wherein the rear wheel assembly includes suspension assemblies disposed on either side thereof, said suspension assemblies comprising at least one biasing means disposed proximal to each pivotal connection of the rear arm and rear wheel assembly.

14. The stroller of claim 13, wherein the at least one biasing means of each suspension assembly comprise first and second springs having different spring constants from each other.

15. The stroller of claim 13, wherein the biasing means comprised a single spring having regions of differential stiffness.

16. The stroller of claim 14, wherein the first spring of the suspension assembly is attached at one end within the rear frame such that when the rear wheel assembly is in the second load bearing position, the first spring is disengaged from the suspension assembly.

17. The stroller of claim 14, wherein the second spring of the suspension assembly is arranged so as to be compressible by the suspension assembly in the second load bearing position.

18. A rear wheel assembly for a stroller comprising : a deck member with two housings configured for receiving at least a portion of the rear frame members of a stroller therein, with said housings having apertures defined therein for pivotal connection therewith; wherein the rear wheel assembly is movable under the rear frame members between a first load bearing position wherein said wheels are retained forward of the pivotal connection with the frame members and a second position wherein said wheels are rearward of the pivotal connection with the frame members .

19. A method of changing a rear wheel assembly pivotally connected to a rear frame section of a stroller from a first load bearing position to a second load bearing position: wherein the method comprises: actuating a latch mechanism to release the rear wheel assembly from the first load bearing position in which two rear frame members of the rear frame section are urged against recesses in the rear wheel assembly and the rear wheels of the rear wheel assembly are located forward of the pivotal connection between the rear wheel assembly and the rear frame of the stroller; and raising the stroller so that that the rear wheel assembly pivots downwardly from underneath the two rear frame members to a second load bearing position wherein the wheels of the rear wheel assembly are located rearward of said pivotal connection between the rear wheel assembly and the rear frame of the stroller.
