Apparatus for connecting a vacuum cleaner and solution tank as a cleaning solution-extraction cleaner

Claim 1

In apparatus for connecting a wet dry vacuum cleaner in an essentially vertically-spaced relationship with a cleaning solution tank for combined use as a cleaning solution extraction-type cleaning apparatus, the wet-dry vacuum cleaner having a body with sidewalls and the solution tank having sidewalls and an open upper mouth, an improved connecting apparatus comprising: at least four elongated arm members joined together at a common point and extending horizontally outward from the common point essentially in a single plane, each of said arm members extending longitudinally from the common point to an outer end thereof, each of said arm members being equally angularly spaced with respect to both of its adjoining arm members, each of said arm members including two transversely spaced apart and longitudinally extending U-shaped edges, each of the U-shaped edges extending longitudinally substantially along the total length of each arm member from the common point to the outer end thereof, the U-shaped edges opening toward one another on an upper vertical side of each arm member, each of said arm members further including means defining a slot extending substantially parallel to and intermediate of the U-shaped edges along said arm members; one first bracket member operatively associated with each arm member, each first bracket member having a base portion and an upstanding projection portion, the upstanding projection portion extending substantially perpendicularly with respect to the base portion, the base portion of each first bracket member being operatively transversely received within the transversely spaced-apart width defined by the transversely spaced-apart U-shaped edges opening toward one another, the receipt of the base portion within the space between the U-shaped edges operatively allowing only longitudinal movement of said first bracket member along the longitudinal dimension of the arm member with which it is associated, the upstanding projection portion contacting the sidewalls of one of either of said vacuum cleaner body or said solution tank; fastening means operatively connected to the base portion of each said first bracket member and extending into the slot defined in said arm member with which the first bracket member is associated, said fastening means being selectively operative to retain said base portion against longitudinal movement along said arm member; and one second bracket member rigidly attached at the outer end of each arm member, each second bracket member having a projection portion extending essentially perpendicularly and vertically downward with respect to the longitudinal dimension of said arm member, the projection portion of said second bracket member contacting the sidewalls of the other one of either of said vacuum body or said solution tank.
