Abstract
An improved brake mechanism for wheels of baby carriages and strollers is integrated in a single unit and is adjustable between a universal or swivel state, a directional state, and a brake state. Transformation among the three states can be realized by a foot pedal. The brake mechanism includes a special V-shaped spring, a sliding collar that locks or unlocks the mechanism between the three states, as well as a colored indicator that is used to display the current state of the wheel.
Claims7
An improved brake mechanism for one or more wheels of a baby carriage, stroller, or the like, said brake mechanism comprising:
- a mounting member (4) adapted for connection to a carriage, stroller, or the like;
- a generally vertically oriented shaft (2) extending through said mounting member and adapted for rotation with respect to said mounting member;
- a wheel support member (9) mounted for rotation about said shaft;
- at least one wheel (12) rotatable mounted to the wheel support member;
- and
- a collar (6) mounted for sliding movement along, said shaft between said mounting member and said wheel support member, said sliding collar being manually movable between first, second and third collar positions, said collar being operably engageable with said mounting member in said first collar position to define a universal state wherein said wheel support member is rotatable about said shaft, said collar being operably engageable and lockable with said mounting member and said wheel support member in said second collar position to define a directional state wherein said wheel support member is fixed with respect to said shaft, and said collar being operably engageable with said wheel in said third collar position to define a brake state wherein said wheel is fixed with respect to said wheel support member;
- whereby movement of said collar along said shaft between said first, second and third collar positions selectively adjusts said brake mechanism between said universal, directional and brake states, respectively.
