1. Field of the Invention
The present invention relates to the field of vacuum cleaners in general, and in particular to an adjustable handle construction for a vacuum cleaner.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 4,662,026; 5,016,315; 5,109,568; and 5,564,160, the prior art is replete with myriad and diverse handle constructions for vacuum cleaners.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical handle construction for vacuum cleaners that can be angularly adjustable, not only to suit the personal preferences of the individual user, but also to reduce the occurrence of carpel tunnel syndrome among individuals who use a vacuum cleaner on a daily basis.
As most individuals in the building maintenance field are all too well aware, even the most ergonomically designed rigid vacuum handle construction can lead to a repetitive motion injury with continued usage.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved type of adjustable vacuum handle construction that cannot only be adjusted to a preferred position, but whose position can be varied to reduce the occurrence of repetitive motion injuries, and the provision of such a construction is a stated objective of the present invention.
