Abstract
A headrest-adjusting mechanism is adapted for use with a stroller. The stroller includes a headrest-supporting tube and a backrest-supporting tube. The headrest-adjusting mechanism is adapted to be connected between the headrest-supporting tube and the backrest-supporting tube in such a manner to allow for rotation of the headrest-supporting tube relative to the backrest-supporting tube from a usable position to a folded position in a predetermined direction.
Claims17
A headrest-adjusting mechanism adapted for use with a stroller, the stroller including a headrest-supporting tube and a backrest-supporting tube, said headrest-adjusting mechanism being adapted to be connected between the headrest-supporting tube and the backrest supporting tube in such a manner to allow for rotation of the headrest-supporting tube relative to the backrest-supporting tube from a usable position to a folded position in a predetermined direction, said headrest-adjusting mechanism comprising:
- a first pivot member adapted to be connected to the headrest-supporting tube and including a first pivot body, said first pivot body having an inner side surface formed with a first retaining groove, and a first position-limiting groove in spatial communication with said first retaining groove;
- a second pivot member pivotally connected to said first pivot member, said second pivot member being adapted to be connected to the backrest-supporting tube and including a second pivot body, said second pivot body having an inner side surface formed with a second retaining groove, and a second position-limiting groove in spatial communication with said second retaining groove;
- a position-limiting member disposed movably within an assembly of said first and second retaining grooves and having at least one locking portion, said position-limiting member being biased to a position wherein said locking portion of said position-limiting member is disposed within said first position-limiting groove in said first pivot member and said second position-limiting groove in said second pivot member to lock said first and second pivot members relative to each other, said locking portion of said position-limiting member as a whole being removable from said first position-limiting groove so as to induce for rotation of the headrest-supporting tube relative to the backrest-supporting tube from said usable position to said folded position;
- and
- a resilient member disposed within said second retaining groove in said second pivot member for biasing said position-limiting member away from said second pivot member, and a pushbutton operable to translate along an axis to thereby push and remove said locking portion of said position limiting member from said first position-limiting groove so as to allow for relative rotation between said first and second pivot members.
A stroller comprising:
- a headrest-supporting tube;
- a backrest-supporting tube;
- and
- a headrest-adjusting mechanism connected between said headrest-supporting tube and said backrest-supporting tube in such a manner to allow for rotation of said headrest-supporting tube relative to said backrest-supporting tube from a usable position and a folded position in a predetermined direction, said headrest-adjusting mechanism including:
- a first pivot member connected to said headrest-supporting tube and including a first pivot body said first pivot body having an inner side surface formed with a first retaining groove, and a first position-limiting groove in spatial communication with said first retaining groove,
- a second pivot member pivotally connected to said first pivot member, said second pivot member being connected to said backrest-supporting tube and including a second pivot body, said second pivot body having an inner side surface formed with a second retaining groove, and a second position-limiting groove in spatial communication with said second retaining groove,
- a position-limiting member disposed movably within an assembly of said first and second retaining grooves and having at least one locking portion, said position-limiting member being biased to a position wherein said locking portion of said position-limiting member is disposed within said first position-limiting groove in said first pivot member and said second position-limiting groove in said second pivot member to lock said first and second pivot members relative to each other, said locking portion of said position-limiting member as a whole being removable from said first position-limiting groove so as to allow for rotation of said headrest-supporting tube relative to said backrest-supporting tube between said usable position and said folded position, and
- a resilient member disposed within said second retaining groove in said second pivot member for biasing said position-limiting member away from said second pivot member, and a pushbutton operable to translate along an axis to thereby push and remove said locking portion of said position-limiting member from said first position-limiting groove so as to allow for relative rotation between said first and second pivot members.
