Abstract
Abstract A hand rake with grasping tines is disclosed including a pair of multitined fork members, a frame assembly for pivotally holding the fork members in spaced facing relation, a handle assembly secured to the frame assembly for carrying the fork members, and a control mechanism for cooperatively varying the pivotal dispositions of the fork members from an open material raking condition to a closed material transporting condition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
78 words
A hand rake with grasping tines comprising, a pair of multitined fork members, frame means for pivotally holding both of said fork members for rocking movement about a pair of separated pivot axes, handle means secured to said frame means for carrying said fork members, and mechanism means for cooperatively varying the pivotal dispositions of both of said fork members with respect to said frame means from an open material raking condition to a closed material transporting condition.
Claim 2
Dependent Claim
78 words
A hand rake with grasping tines comprising, a pair of multitined fork members, frame means for pivotally holding both of said fork members for rocking movement about a pair of separated pivot axes, handle means secured to said frame means for carrying said fork members, and mechanism means for cooperatively varying the pivotal dispositions of both of said fork members with respect to said frame means from an open material raking condition to a closed material transporting condition.
Claim 3
Dependent Claim
26 words
The hand rake of claim 1 wherein each of said fork members has a tubular body and a plurality of flexibly resilient tines dependingly secured thereto.
Claim 4
Dependent Claim
35 words
The hand rake of claim 2 wherein said frame means includes front bearing means and rear bearing means respectively disposed in alignment with said axes for pivotally supporting said tubular bodies of said fork members.
Claim 5
Dependent Claim
31 words
The hand rake of claim 3 wherein said mechanism means includes coupling means intermediately connected between said tubular bodies for affecting simultaneously coordinated opening or closing movement of said fork members.
Claim 6
Dependent Claim
37 words
The hand rake of claim 4 wherein said mechanism means includes a control lever rockably coupled to said handle means and means connected to said control lever and said coupling means for selectively manipulating said coupling means.
Claim 7
Dependent Claim
32 words
The hand rake of claim 5 wherein said mechanism means includes spring means for loadably biasing said mechanism means and both of said fork members pivotally apart and into said open condition.
Claim 8
Dependent Claim
99 words
A hand rake with grasping tines comprising, a pair of fork members individually having a plurality of flexible tines, a frame assembly for pivotally holding both of said fork members for rocking movement about a pair of longitudinally spaced apart and parallel pivot axes, a handle which is effectively secured to said frame assembly for carrying said fork members, and a control mechanism for cooperatively and simultaneously varying the pivotal dispositions of both of said fork members and said flexible tines with respect to said frame assembly from an open material raking condition to a closed material transporting condition.
Claim 9
Dependent Claim
99 words
A hand rake with grasping tines comprising, a pair of fork members individually having a plurality of flexible tines, a frame assembly for pivotally holding both of said fork members for rocking movement about a pair of longitudinally spaced apart and parallel pivot axes, a handle which is effectively secured to said frame assembly for carrying said fork members, and a control mechanism for cooperatively and simultaneously varying the pivotal dispositions of both of said fork members and said flexible tines with respect to said frame assembly from an open material raking condition to a closed material transporting condition.
Claim 10
Dependent Claim
33 words
The hand rake of claim 7 wherein said control mechanism includes coupling means connected between said fork members for effecting simultaneous opening or closing movement of them both relative to said frame assembly.
Claim 11
Dependent Claim
48 words
The hand rake of claim 8 wherein said control mechanism includes rockable lever means mounted on the upper end of said handle and operatively connected to said coupling means for allowing convenient selective manipulation of said coupling means and said fork members with a relatively high mechanical advantage.
Claim 12
Dependent Claim
28 words
The hand rake of claim 9 including resilient means for loadably biasing said control mechanism and both of said fork members pivotally apart and toward said open condition.
