Abstract
A stroller includes a main frame, a backrest, a backrest adjustor, and a linkage device. There is a guide rail formed inside the backrest adjustor. A positioning part of the backrest engages with the guide rail. When a handle of the linkage device is moved upward, a connecting component of the linkage device drives a pushing component of the linkage device to move upward along a supporting rod of the backrest. Accordingly, a protruding portion of the pushing component drives the backrest adjustor to rotate relative to a supporting frame of the main frame so as to release the positioning part from the guide rail.
Claims20
A stroller comprising:
- a main frame formed with two supporting frames disposed at two sides of the stroller respectively, the two supporting frames being symmetrical with each other;
- a seat frame;
- a backrest disposed between the two supporting frames comprising:
- a supporting rod structure, one end of which is pivotally connected to the seat frame;
- and
- a positioning part disposed on the supporting rod structure;
- a backrest adjustor, one end of which is pivotally connected to one of the two supporting frames, having a guide rail being formed in the backrest adjustor for engaging with the positioning part;
- and
- a linkage device disposed on the backrest comprising:
- a handle;
- a pushing structure sheathing the supporting rod structure in a sliding manner and having a protruding portion, the protruding portion abutting against the backrest adjustor;
- and
- a connecting component disposed between the handle and the pushing structure for driving the pushing structure to move upward along the supporting rod structure when the handle of the linkage device is moved upward, so that the protruding portion of the pushing structure drives the backrest adjustor to rotate relative to the supporting frame of the main frame so as to release the positioning part from a positioning groove of the guide rail.
A backrest recline device of a stroller, which the stroller has supporting rods of a backrest therein, comprising:
- a positioning part disposed on the supporting rod;
- a backrest adjustor, one end of which is pivotally connected to the stroller, having a plurality of positioning grooves therein which is capable of engaging with the positioning part;
- and
- a linkage device disposed on the backrest comprising:
- a handle;
- a pushing structure sheathing the supporting rod in a sliding manner and having a protruding portion, the protruding portion abutting against the backrest adjustor;
- and
- a connecting component disposed between the handle and the pushing structure for driving the pushing structure to move upward along the supporting rod when the handle of the linkage device is moved upward;
- wherein when the positioning part engages with one of the positioning grooves, the pushing structure rests on the positioning part as well.
