Abstract

Abstract An improved snow shovel construction (10) comprising a novel continuous diameter wooden handle unit (11) and a shovel blade unit (12); wherein, the blade unit (12) limits the volume and the weight carrying capacity due to its dimensioning; whereby, the handle unit (11) and the shovel blade unit (12) are capable of being "flexed" backwardly and "flipped" forwardly in the act of shoveling snow or slush (K).

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 203 words
An improved flexible snow shovel construction comprising: a resilient flexible snow shovel blade means comprising a main blade element having side walls and a rear wall, wherein the volume capacity of the snow shovel blade element is limited by the dimensions thereof, and the weight bearing capacity of the flexible snow shovel blade element is further restricted by the resilient material from which it is fabricated; and, a uniformly proportioned flexible wooden handle means comprising a flexible handle member having a length "L" to diameter "d" ratio wherein the minimum value of "L" equals thirty inches and the minimum value of "d" equals sixty-three hundredths of an inch; and, wherein for every inch above the minimum value of the length "L" the value of the diameter "d" will be increased by one hundredth of an inch; whereby the flexible nature of both the blade means and the handle means will cause a flexure along the combined length of the blade and handle means when the blade element is loaded with snow and wherein the unloading of the snow from the blade element will be accompanied by a flipping action as the said flexible blade and handle means are returned to their unflexed state.
Claim 2
Dependent Claim 203 words
An improved flexible snow shovel construction comprising: a resilient flexible snow shovel blade means comprising a main blade element having side walls and a rear wall, wherein the volume capacity of the snow shovel blade element is limited by the dimensions thereof, and the weight bearing capacity of the flexible snow shovel blade element is further restricted by the resilient material from which it is fabricated; and, a uniformly proportioned flexible wooden handle means comprising a flexible handle member having a length "L" to diameter "d" ratio wherein the minimum value of "L" equals thirty inches and the minimum value of "d" equals sixty-three hundredths of an inch; and, wherein for every inch above the minimum value of the length "L" the value of the diameter "d" will be increased by one hundredth of an inch; whereby the flexible nature of both the blade means and the handle means will cause a flexure along the combined length of the blade and handle means when the blade element is loaded with snow and wherein the unloading of the snow from the blade element will be accompanied by a flipping action as the said flexible blade and handle means are returned to their unflexed state.
Claim 3
Dependent Claim 15 words
An improved snow shovel construction as in claim 1 wherein the resilient material is plastic.
