Abstract

The invention described provides a nozzle that includes a pivoted wand to permit relative movement in a vertical plane between the wand and nozzle during manipulation by the operator. The center for the pivot for the wand is located at floor level. This permits friction generated forces that are imparted to the nozzle to be imposed so as to prevent unbalanced moments being generated tending to tip the nozzle during its movement over a floor or carpeting.

Claims

1. A pivoting nozzle and wand arrangement including;

(a) a nozzle body,

(b) a bottom plate attached to the bottom of said nozzle body,

(c) a floor centered pivot means adjacent said bottom plate extending into said nozzle body for freely pivoting said wand,

(d) whereby friction induced forces generated by nozzle movement over a floor pass through said floor centered pivot means to produce substantially no unbalanced moment to the nozzle.

2. A nozzle including;

(a) a nozzle body,

(b) a first pivot structure mounted with said nozzle body and non-rotatably fixed relative thereto and having its center located substantially at floor level; and

(c) a wand and a second pivot structure non-rotatably fixed relative to said wand and having its center at substantially floor level, said wand being directly pivoted to said nozzle by pivoting cooperation of said first and second pivot structures,

(d) whereby friction induced forces generated by nozzle movement over a floor produce substantially no unbalanced moment to the nozzle.

3. A pivoting nozzle and wand arrangement including;

(a) a nozzle body,

(b) a bottom plate attached to the bottom of the nozzle body,

(c) an arcuately shaped portion formed in said bottom plate,

(d) at least one arcuately shaped portion formed in said nozzle body,

(e) a wand piece disposed between said arcuately shaped portions and having surfaces cooperating with said nozzle body and bottom plate arcuate shaped portions,

(f) said arcuately shaped portions forming conforming surfaces for pivotal reception of said wand piece,

(g) said conforming arcuately shaped portions having as their center a pivot point,

(h) said pivot point being located at floor level,

(i) whereby friction induced forces generated by nozzle movement over a floor produce substantially no unbalanced moment to the nozzle.

4. The pivoting nozzle and wand arrangement of claim 3 wherein;

(a) said arcuately shaped portion formed in said bottom plate is apertured to form a suction opening for said nozzle.

5. The pivoting nozzle and wand arrangement of claim 3 wherein;

(a) a seal is provided for the end of said wand piece,

(b) said seal riding on said arcuately shaped portion formed in said bottom plate.

6. The pivoting nozzle and wand arrangement of claim 3 wherein;

(a) said wand piece is hollow for the passage of suction air.
