ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a rake, and more particularly to a garden or lawn rake device having a gripping and/or retracting mechanism.
2. Description of the Prior Art
The closest prior art of which the applicant is aware is his prior U.S. Pat. No. 5,553,447 to Hsu and comprises a number of tines that may be retracted to a folding or storing configuration. However, the rake may not be used to gripping the tree leaves and grass gathered by the rake.
The other typical rakes comprise two groups of tines symmetrically provided on the opposite lateral sides of the rod handle and movable into a generally mutual overlaying relationship for gripping the tree leaves and grass. However, a greatly complicated configuration is required for pivotally coupling the two groups of tines to the rod handle and for allowing the two groups of tines to be rotated about the rod handle to the overlaying relationship. One of the typical rakes is disclosed in U.S. Pat. No. 5,414,982 to Darnell.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional rakes.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a rake device including an auxiliary tine device rotatable about a first rake for gripping the tree leaves and grass.
The other objective of the present invention is to provide a rake device in which the first rake includes a number of tines that may be expanded to an open and working position and that may be retracted to a folding and storing position.
In accordance with one aspect of the invention, there is provided a rake device comprising a rod including a front end, a first rake secured to the front end of the rod, a second rake pivotally secured to the front end of the rod at a pivot shaft, the pivot shaft being lateral relative to the rod, and means for rotating the second rake toward the first rake to grasp leaves and grass.
The second rake includes at least one cam provided thereon, the first rake includes a front portion and includes at least one first actuator provided thereon for engaging with the at least one cam and for rotating the second rake toward the front portion of the first rake to grasp leaves and grass. The first rake includes at least one tine having a depression formed therein for receiving the at least one cam and for allowing the second rake to be dependent downward relative to the first rake before the at least one first actuator is engaged with the at least one cam to rotate the second rake toward the first rake.
The depression of the first rake includes a first end having the at least one first actuator formed thereon and includes a second end having a second actuator formed thereon for engaging with the second rake and for rotating the second rake toward the rod at a folding position. A retaining device is further provided for retaining the second rake at the folding position and includes a catch slidably engaged on the rod and having at least one hook extended therefrom for engaging with and for retaining the second rake to the rod at the folding position. A projection is extended from the first rake to engage with the second rake and to rotate the second rake toward the rod before the catch is engaged with the second rake. The second rake includes an extension extended therefrom for engaging with the projection and for allowing the second rake to be further rotated toward the rod.
A frame is further secured to the first end of the rod, the second rake is pivotally secured to the frame at the pivot shaft. The first rake includes a plurality of tines, the frame includes a plurality of apertures formed therein for receiving the tines of the first rake. A handle is slidably engaged on the rod and secured to the first rake for allowing the handle to move the tines of the first rake relative to the frame. A latch is further provided for detachably securing the handle to the rod. A tube is secured between the handle and the first rake for adjusting a distance between the handle and the first rake.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
