A carpet sweeper, vacuum cleaner or other upright floor cleaning device includes a base unit (2) and a handle (6) freely pivoted on the base unit for translation over a floor (3). The handle pivots in a vertical plane (9) extending transverse to the base unit support wheel axles (5). A handle grip (10) includes a first grip portion (12) which is coaxial with the handle and forms an extension thereof. The outer end of the first grip portion connects with a second grip portion (14) which comprises an arm (15) graspable by the operator, with the arm extending forwardly (upwardly when in use) of the handle. The arm is disposed in the vertical plane (9) and is bowed or curved from its point of anchorage with the first grip portion (12) to its opposite end, which is disposed in a plane (19) transverse to the first grip portion and passing between the latter\s ends. The curvature of the outer arm surface is adapted to nest in a cup formed by the operator\s closed hand. The said opposite end of the arm merges into a third grip portion which forms a brace (20) extending diagonally rearwardly (downwardly when in use) back to and connecting with the first grip portion. Instead of the operator\s fingers being arrayed along the handle at an acute angle to a horizontal plane containing the wheel axles (5), as in prior upright cleaning devices, the fingers are arrayed normal to the pivotable handle and at an obtuse angle to the axles, thus creating a stronger wrist position. Also, since the handle is effectively below the grip during use, the handle itself is pivotally positioned at a smaller angle to the floor than previously.

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.
