Claim 1
Independent Claim
290 words
An upright floor cleaner comprising in combination: (a) a base unit for reciprocable translation over a floor to be cleaned, (b) wheel means mounted on axle means and adapted to support said base unit on said floor, (c) an elongated handle pivotally mounted at its inner end to said base unit and thus pivotable relative to said base unit and to said floor during said translation, said handle being sufficiently long that said floor cleaner can be manipulated by a user in a standing position when said base unit is engaging the floor, (d) a handle grip mounted on the outer end of said handle forming a straight extension of said handle and mounted for movement with said handle during use in a plane disposed vertically to a said floor and normal to said axle means, (e) said handle grip including a graspable arm attached to the outer end of said handle grip and extending generally laterally upwardly in a direction away from the floor when in use and at substantially a right angle with respect to the longitudinal axis of said handle during use and being graspable by the hand of a standing operator, (f) said arm being sufficiently long in a direction generally laterally and upwardly away from said handle that it will accommodate the width of a user's hand grasping said arm, so that the forces applied by the said standing operator to translate the device over the floor are applied generally parallel to the operator's fingers to thereby provide a strong wrist position for the operator during said reciprocable translation, and so that said arm positions said handle below the operator's hand to thereby minimize the angle of said handle relative to said floor during use.

An upright floor cleaner comprising in combination: (a) a base unit for reciprocable translation over a floor to be cleaned, (b) wheel means mounted on axle means and adapted to support said base unit on said floor, (c) an elongated handle pivotally mounted at its inner end to said base unit and thus pivotable relative to said base unit and to said floor during said translation, said handle being sufficiently long that said floor cleaner can be manipulated by a user in a standing position when said base unit is engaging the floor, (d) a handle grip mounted on the outer end of said handle forming a straight extension of said handle and mounted for movement with said handle during use in a plane disposed vertically to a said floor and normal to said axle means, (e) said handle grip including a graspable arm attached to the outer end of said handle grip and extending generally laterally upwardly in a direction away from the floor when in use and at substantially a right angle with respect to the longitudinal axis of said handle during use and being graspable by the hand of a standing operator, (f) said arm being sufficiently long in a direction generally laterally and upwardly away from said handle that it will accommodate the width of a user's hand grasping said arm, so that the forces applied by the said standing operator to translate the device over the floor are applied generally parallel to the operator's fingers to thereby provide a strong wrist position for the operator during said reciprocable translation, and so that said arm positions said handle below the operator's hand to thereby minimize the angle of said handle relative to said floor during use.
Claim 3
Dependent Claim
45 words
The upright floor cleaner of claim 1 wherein said graspable arm of said handle grip further includes an outer rear surface having a curved convex portion comprising means to nest in the cupped inner portion of the operator's closed hand during use of the cleaner.
Claim 4
Dependent Claim
28 words
The upright floor cleaner of claim 2 wherein said graspable arm (15) of said handle grip (10) further includes an inner surface (18) of generally arcuate concave curvature.
Claim 5
Dependent Claim
29 words
The upright floor cleaner of claim 2 in which said curved convex portion merges into a forwardly extending generally planar portion spaced from and generally parallel to said handle.
Claim 6
Dependent Claim
75 words
The upright cleaner of claim 1 wherein said handle grip further comprises: (a) a generally straight grip portion disposed at the upper end portion of said handle and axially aligned therewith, said grip portion having an outer end portion connected to one end of said graspable arm, (b) and a brace connected to the other end of said arm and extending diagonally downwardly into connecting relationship with an inner end portion of said grip portion.
Claim 7
Dependent Claim
45 words
The upright cleaner of claim 5 wherein the connection of said brace to the said other end of said graspable arm is disposed in a plane which is transverse to said grip portion and which passes therethrough between its said inner and outer end portions.
Claim 8
Dependent Claim
29 words
The upright cleaner of claim 1 in which said arm curves forwardly slightly towards said base unit as it proceeds upwardly away from said longitudinal axis of said handle.
Claim 9
Dependent Claim
35 words
The upright cleaner of claim 7 in which said upwardly and forwardly curving arm terminates at a generally diagonal brace which extends from said arm forwardly and downwardly to said longitudinal axis of said handle.
