ABSTRACT:
A one piece plastic injection molded snow shovel in which the blade, synthetic plastic handle stem and D-top handle are molded in one operation and a finished unit is produced from one cycle of the molding machine. A generally rectangular scoop of synthetic plastic has an integral generally cylindrical hollow handle stem extending centrally outwardly from the rear edge of the scoop. One embodiment has an inwardly reinforced cylindrical stem extending inward of the scoop for several inches from the back edge and then outward for a space normally grasped by a hand of the shoveller. A second embodiment has the handle stem entering from the back of the scoop with a section including an arcuate shell having an arc between about 220.degree.-235.degree. and with a central reinforcing rib diametetrically of the arc. In either case, much of the outwardly extending handle stem consists of upwardly opening arcuate shell between about 220.degree.-235.degree. together with an upper face of an open X-crossing structure making a light but strong handle. A third embodiment has a hollow cylindrical handle stem of which almost the entire length has a plurality of spaced longitudinally extending short reinforcing projections extending radially inwardly.
