  • Patent number: 5487260
    Abstract: A lawn rake having a clip member extending from the upper surface thereof to retain gardening gloves or other items with the rake between uses, reducing the likelihood of the gloves being misplaced. The hub of the rake head is made up of wedge-shaped sections. The upper surfaces of alternate ones of the wedge-shaped sections define a first arcuate surface, while the upper surfaces of the intermediate ones of the wedge-shaped sections define a second arcuate surface, offset from the first arcuate surface, thereby strengthening the hub and inhibiting twisting thereof. The rake tines extend from the hub and continue the wedge shape and arcuate configuration of the hub. Each tine has a rib extending down its upper surface centrally between the tine edges. A spreader bar interconnects all the tines. An outer wall extends downwardly from the lower edge of the outside surface of the hub and of each of the outermost tines.
