1. A rake comprising:
a handle with an upper portion, an intermediate portion and a lower portion; a pair of oppositely disposed frames pivotally attached to said lower portion, said pair of oppositely disposed frames having a plurality of tines; an articulating mechanism comprising:
a pair of brackets fixedly coupled to said lower portion;a pair of rods fixedly coupled between said pair of brackets; a handle collar slidable on said handle, said handle collar coupled to a rod collar by a pair of connecting members, said rod collar slidable on one of said pair of rods; a pair of connector rods hingedly coupled between said rod collar and said pair of oppositely disposed frames; wherein said pair of rods are attached between an upper pivot bracket coupled to said lower portion of said handle, and a lower pivot bracket; wherein each of said frames comprises an upper arm and a lower arm, having said plurality of tines secured thereto; wherein said pair of rods are axially aligned with said handle, wherein said rods are parallel to each other and fulfill the dual function as an extension to the handle and as a guide for the slidable rod collar, allowing for the functioning of the articulating mechanism; wherein said upper arm is pivotally connected to said upper pivot bracket and said lower arm is pivotally connected to said lower pivot bracket; wherein said upper arm is coupled to an upper pivoted disc rotatably mounted on said upper pivot bracket and said lower arm is coupled to a lower pivoted disc rotatably mounted on said lower pivot bracket; and
whereby sliding said handle collar causes said rod collar to slide in a synchronized way and provides a force to said pair of connector rods to pivot said pair of oppositely disposed frames towards one other or away from one another. |
