发明名称 Snow shovel
摘要 An improved snow shovel for reducing the suction of snow to shovel while still maintaining the overall strength of the shovel. The improved snow shovel has a face or blade scoop portion that has an array of vertical or longitudinally extending slots or slits that penetrate through the entire blade scoop portion of the snow shovel. The array is arranged with the slots aligned vertically in a top to bottom arrangement. The slots are disposed in a set of preferably one to two slots per set. The sets of slots are arranged in a symmetric pattern on the face of the shovel to ensure uniform distribution of the reduction of snow to the shovel and to ensure uniformity of the overall strength of the shovel. The shovel face can be flat or curved.

主权项 1. A snow shovel comprising: Said snow shovel having a blade that has a generally rectangular shape being bounded by a left edge, a right edge, a top edge, and a bottom edge, of said bottom edge of said blade and said blade also having a front face and a rear face and has on its front face an array of vertical or longitudinally extending slits penetrating through said entire blade through said front face and said rear face, said slits being arranged in an array with said slits being aligned vertically in a top to bottom arrangement and being disposed in sets of one to two slits per set; said sets of slits being arranged side to side with respect to each other along a width of said face of said shovel; said sets of slits being arranged in a symmetric pattern of said pattern of said slits of one to two slits per set contained within the boundaries of said front and rear faces so as not to extend all the way to a bottom edge of said front and rear faces of said shovel to ensure uniform distribution of the reduction of suction of snow to the shovel for releasing the snow from the front face of the blade of the shovel and to ensure uniformity of the overall strength of the shovel.
