Abstract
Abstract A hand rake having a plurality of tines whose spread is adjustable in width for different operations. The tines extend through a guide at the bottom of the rake handle and are secured at their upper end to a retainer which slides along the handle. A special retainer structure clamps the upper end of the tines tightly so that the rotational position of the retainer is maintained by the tines in a fixed position with respect to the guide position. A split collar and locking nut arrangement facilitate the locking of the retainer with one hand in various adjusted positions along the handle. The handle can be made in two parts for separation when not in use. A hook extends from the guide for hanging the rake when not in use.

Total Claims: 12
Claim 1
Independent Claim
243 words
An adjustable hand rake comprising: a handle having a longitudinal extent; a guide member secured to one end of said handle, said guide member having a plurality of laterally spaced apart holes; a tine retainer slidably mounted on said handle, said retainer including a transversely extending one piece cage and a one piece transversely extending support plate, said cage having an axial bore through which said handle extends; said support plate having a transversely extending slot and a transversely extending indentation angularly extending from said transversely extending slot to a bottom edge of said support plate; a plurality of tines extending through said guide member holes, the upper ends of said tines being bent outwardly, the upper portion of said tines being positioned in said indentation with said upper bent ends extending into said transversely extending slot; said cage having a transversely extending wide base flange covering said tines upper portion; said support plate and said cage wide base flange having transversely extending portions extending longitudinally of said slot and parallel to said tines in clamping engagement therewith longitudinally of said outwardly bent portions; and means Rigidly clamping said support plate to said cage wide base flange for rigidly retaining said tines in said indentation for movement laterally within said indentation but otherwise preventing said tines from movement in said indentation, said rigidly clamped tines maintaining said tine retainer in a fixed angular position on said handle with respect to said guide member.
Claim 2
Dependent Claim
