The stroller comprises a main frame having a first seat support for supporting a first seat and a first reclinable backrest frame for supporting a first backrest. A first reclining mechanism is connected to the backrest frame and the main frame for selectively pivotally moving the backrest relative to the main frame, which includes at least one pivot mechanism. A first canopy mechanism is also connected to the main frame which includes a first tensioning mechanism, a first canopy frame connected to one end of a canopy and a second canopy frame connected to the other end of the canopy.
Claims19
A reclining mechanism for reclining a seat backrest of a stroller comprising:
- a first pivot member for connecting to a frame of the stroller;
- a second pivot member for connecting to the backrest, wherein the second pivot member is pivotably and displaceably connected to the first pivot member to selectively position the backrest relative to the frame;
- the second pivot member includes an abutment member adapted to engage one of a plurality of complementary abutment notches on the first pivot member, a portion of the abutment member having a first shape, and a portion of the abutment notch having a second shape generally corresponding to the first shape to allow the abutment notch to receive the abutment member;
- a spring connected to the first and second pivot members to urge the abutment member toward one of the abutment notches;
- and
- the abutment member including a first forward surface and a second rearward surface, the first forward surface being shaped differently than the second rearward surface, the first and second surfaces enabling the backrest to pivot in a first direction but preventing the backrest from pivoting in the other direction when the abutment member is engaged with one of the abutment notches.
A reclining mechanism for reclining a seat backrest of a stroller comprising:
- a first pivot member for connecting to a frame of the stroller;
- a second pivot member for connecting to the backrest, wherein the second pivot member is pivotably and displaceably connected to the first pivot member to selectively position the backrest relative to the frame;
- the second pivot member includes an abutment member adapted to engage one of a plurality of complementary abutment notches on the first pivot member,
- a spring connected to the first and second pivot members to urge the abutment member toward one of the abutment notches;
- wherein the second member has a longitudinal slot defining a longitudinal direction, and the first member includes a guide disposed in the slot;
- wherein the second member is movable with respect to the first member along the longitudinal direction of the slot;
- and
- the second member includes a chamber, the abutment member being formed adjacent one end of the chamber, the spring being positioned substantially within the chamber.
A reclining mechanism for reclining a seat backrest of a stroller comprising:
- a first pivot member for connecting to a frame of the stroller;
- a second pivot member for connecting to the backrest, wherein the second pivot member is pivotably and displaceably connected to the first pivot member about a pivot guide to selectively position the backrest relative to the frame, the backrest being located on a first side of the pivot guide;
- the second pivot member includes an abutment member adapted to engage one of a plurality of complementary abutment notches on the first pivot member, the abutment member disposed on a second side of the pivot guide opposite to the first side, a portion of the abutment member having a first shape, and a portion of the abutment notch having a second shape generally corresponding to the first shape to allow the abutment notch to receive the abutment member;
- a spring connected to the first and second pivot members to urge the abutment member toward one of the abutment notches;
- and
- the abutment member including a first forward surface and a second rearward surface, the first forward surface being shaped differently than the second rearward surface, the first and second surfaces enabling the backrest to pivot in a first direction but preventing the backrest from pivoting in the other direction when the abutment member is engaged with one of the abutment notches.
