Patent ID: 6976686

Claim:
A stroller, comprising: a front frame having two front leg frames, a back frame constructed to support a seat frame thereon, and a handle frame having two handle arms upwardly extended from said front frame; and a detachable front guider arrangement, comprising: a front guider; and a pair of coupling means for detachably coupling two ends of said front guider with said two front leg frames of said front frame respectively, each of said coupling means comprising: at least a locking latch, wherein said two locking latches are opposedly and outwardly protruded from outer sides of said two front leg frames of said front frame respectively, wherein a predetermined length of a neck portion of each of said locking latches is protruded from said outer side of said respective front leg frame; and a joint member, wherein said two joint members are mounted on said two ends of said front guider and detachably coupled with said two front leg frames respectively, wherein each of said joint members comprises a head joint connecting with said respective end of said front guider and a base joint which has a U-shaped cross section comprising inner and outer parallel supporting walls in a parallel manner to fittedly mount said respective front leg frame between said inner and outer supporting walls, wherein at least a locking groove is formed on said outer supporting wall of each of said joint members and arrangement to engage with said respective locking latch, wherein each of said locking grooves is an elongated groove formed at an edge of said respective outer supporting wall, wherein an opening of said locking groove is provided at a bottom end of said outer supporting wall in such a manner that said joint members are engaged with said two front leg frames respectively while said two locking latches are engaged into said two locking grooves respectively in a vertical movable manner, so as to lock up said two joint members on said two front respectively, wherein an inner biasing surface is formed on an inner side of said respective base joint to bias against said respective front leg frame, wherein when said base joints are mounted on said front leg frames respectively, said inner biasing surfaces of said base joints are frictionally engage with said front leg frames respectively and guides said locking latches to align with said openings of said locking grooves respectively in such a manner that said locking latches are slidably engaged with said locking grooves respectively when said inner biasing surfaces of said base joints are downwardly slid along said front leg frames respectively.
