SHAG RUG ADAPTER FIELD OF THE INVENTION This inventionrelates generally to vacuum cleaners and particularly to vacuum cleaners adapted for use with a plurality of interchangeable attachments for effecting various types of cleaning operations.
SUMMARY OF THE INVENTION- This invention is of a vacuum cleaning tool for use in cleaning shag rugs and the like. While it can be em ployed as an entire tool designed to be attached di-v rectly to a vacuum wand. it is advantageously designed as an adapter for attachment to a standard vacuum cleaner rug tool. In a preferred embodiment, the tool has (1 a plurality of hollow rake stands whose ends are alternately bevelled forward and backward to create a scissor-like agitation of the pile as the adapter is drawn through it. (2) a plurality of solid rake toes spaced intermediate the rake stands to comb the pile and to act as a divider between the oppositely directed air currents flowing to the rake stands, and (3) a plurality of lint slots spaced intermediate the rake stands.
BRIEF DESCRIPTION OF THE DRAWING FIG I is a rear view of a shag rug adapter made in accordance with the present invention and detachably mounted on a standard vacuum cleaner rug tool (shown in phantom).
FIG. 2 is a bottom view of the adapter and standard rug tool shown in FIG. 1.
FIG. 3 is a sectional view taken along the lines 3-3 in FIG. I but omitting the standard rug tool.
FIG. 4 is a sectional view taken along the lines 4-4 in FIG. 1 but omitting the standard rug tool.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIGS. 1 and 2 show an adapter detachably mounted on a standard vacuum cleaner rug tool 12 (shown in phantom). The adapter 10 can be made of plastic. metal. or any other suitable material. The detachable mounting can be effected by dimensioning the parts for a moderate squeeze fit or by providing a spring catch, both in manners well known in the art, or by any other appropriate method. The standard rug tool 12 has a downwardly opening face (not shown expressly) which. in conjunction with an upwardly opening face 14 on the adapter 10, defines an air-tight vacuum chamber. The standard rug tool 12 includes a mounting 16 by which the standard rug tool 12 can be connected to the wand of a vacuum cleaner, allowing the chamber defined by the downwardly opening face of the standard rug tool 12 and the upwardly opening face 14 of the adapter 10 to communicate with the vacuum supplied by the vacuum cleaner.
A plurality of rake stands 18, also called rake tines are mounted on the work face of the adapter 10. Each of the rake stands 18 contains a passageway leading from the air-tight vacuum chamber to the end of the rake stand removed from the work face 20. The ends of the rake stands 18 removed from the work face 20 are bevelled alternately forward and backward (see particularly FIG. 1) so that the vacuum from the airtight vacuum chamber is alternately directed forward and backward when the ends of the rake stands 18 are in contact with a relatively impervious surface, such as the base of a rug. This construction creates a violent scissor-like agitation of the pile on shag rugs as the tool is drawn through it. resulting in a remarkably effective cleaning of the rug.
Intermediate the rake stands 18, solid rake toes 22, also called rake toes are likewise mounted on the work face 20 of the adapter 10. The rake toes 22 comb the pile on shag rugs as the tool is drawn through it, and they act as a divider between the oppositely directed aircurrents flowing to the rake stands 18.
Finally. lint slots 24 are provided in the work face 20 of the adapter 10 intermediate the rake stands 18. As may best be seen in FIG. 4, lint slots 24 provide direct communication between the work face '20 of the adapter 10 and the air-tight vacuum chamber. This construction provides additional cleaning power at a higher stratum of the pile than the bevelled rake stands 18, thereby maximizing the effectiveness of the cleaning operation.
