Brief Description of the Drawin~~Fi~ures The accompanying drawing incorporated in and forming a part of this specification, illustrates several aspects of the present invention, and together with the description serves to explain certain principles of the invention. In the drawing:
Figure 1 is a perspective view showing the electrified extension hose of the present invention connected between a wand and an original equipment hose of a canister vacuum cleaner;
Figure 2 is a detailed, perspective view of a first coupler on a first end of the hose body;
Figure 3 is a detailed, perspective view of the second coupler on the second end of the hose body; and Figure 4 is a detailed, cross-sectional view showing the interconnection of a first coupler on the first end of the extension hose with a coupler on another hose such as an original equipment hose of the canister vacuum cleaner illustrated in Figure I.
Reference will now be made in detail to the present preferred embodiment of the invention, an example of which is illustrated in the accompanying drawing.
Detailed Description of the Invention Reference is now made to Figure 1 showing the electrified extension hose 10 of the present invention in use interconnecting the original equipment hose H and wand W of the canister vacuum cleaner V. As illustrated, that vacuum cleaner V includes a canister housing C mounted on wheels L for movement across the floor. The wand W carries a powerhead P including a motor driven rotary agitator A. A switch S on the wand W
allows the operator to turn on both the suction generator G in the canister housing and the motor M of the powerhead P for driving the agitator A.
Advantageously, the extension hose 10 of the present invention includes the necessary electrical circuitry to allow proper interconnection between the switch S on the wand W, the motor M in the powerhead P and the suction generator G in the canister housing C to allow proper operation.
The electrified extension hose 10 includes a flexible hose body 12 including a lumen that defines a dirty air pathway. The hose body 12 has a first end 14 and a second end 16. The hose body 12 is constructed from a S
flexible resin that is molded around a coiled reinforcing wire I8, a first insulated electrical conductor 20 and a second insulated electrical conductor 22 (see Figure 3). For many applications the hose body 12 also includes a third insulated electrical conductor (not shown). The wall of the body 12 is collapsible with a resilient memory to assume a re~~racted or shortened length. Thus, when at rest the electrified extension hose 10 assumes a static length A. In contrast, when in use such as when the wand W is manipulated for above-floor cleaning, the hose 10 may be stret<;hed to a length B where B > A by extending the collapsible wall of the body 12. Additional details relating to the construction of electrified stretch hoses of the type incorporated into the present invention may be gleaned from reviewing various prior art references including, for example, U.S. Patent 5,555,915 to Kanao.
A first coupler 26 is provided on the first end 14 of the hose body 12 while a second coupler 28 is provided on the second end 16 of the hose body. The first coupler 26 includes an outer hard plastic sleeve 30 constructed, for example, from ABS or polycarbonate plastic and an inner soft plastic sleeve 32 constructed of, for example, polyvinylchloride or tetrapolyfluoroethylene.
As further illustrated in Figure 2, the first coupler 26 carries a first electrical terminal 34 and a second electrical terminal 36. Further, the first coupler 26 carries a first connector 3 8 which may, for example, take the form of a male connector such as a projecting lug.
As illustrated in Figure 3, the second coupler 28 includes an outer sleeve 40 constructed from a soft plastic such as polyvinylchloride or tetrapolyfluroethylene and an inner sleeve 42 constructed from a hard plastic such as ABS or polycarbonate. Additionally, the second coupler 28 carries a third electrical terminal 44 and a fourth electrical terminal 46. In addition, the second coupler 28 carnes a second connector 48. That second connector 48 may take the form of a female connector sized and shaped to cooperate and mate with the first connector 38 of the first coupler 26. Thus, as illustrated, the second connector 48 may take th.e form of a groove such as the hook-shaped groove illustrated in drawing Figure 3 .
It should be appreciated that the first conductor 20 runs through the hose body 12 of the electrified extension hose 10 and interconnects the first electrical terminal 34 on the first coupler 26 with the third electrical terminal 44 on the second coupler 28. similarly, the second electrical conductor 22 runs through the hose body 12 of the electrified extension hose 10 and interconnects the second electrical terminal 36 on the first coupler 26 with the fourth electrical terminal 46 on the second coupler 28.
By providing standard first and second, mating electrical couplers 26, 28 on all hoses and either a first or second coupler on the wand W and the opposite thereof on the canister housing C, one may interconnect any number of electrified extension hose sections 10 of the present invention to provide a working hose between the canister housing C and the wand W of substantially any desired length.
The interconnection of the first end 14 and, therefore, first coupler 26 of the extension hose 10 of the present invention with the free or wand end of the original equipment hose H is illustrated in Figure 4. As should be appreciated, the first coupler 26 is of a diameter that may be snugly received in the firmer diameter of the original equipment hose coupler O which corresponds to the second coupler 28. Accordingly, the first coupler 26 is aligned with the coupler O so that the first connector 38 is inserted into the second connector 48 as the two couplers are pushed together. During this interconnection, the first coupler is twisted slightly so that the first connector 38 follows the curve of the hook-shaped groove of the second connector 48. When the first coupler 26 is fully seated in the coupler O, the first terminal 34 exposed through the outer wall of the first coupler is brought into contact with the third terminal 44 exposed through the inner wall of the second coupler O. Similarly, the second terminal 36 exposed through the outer wall of the first coupler 26 is brought into contact with the fourth terminal 46 exposed through the inner wall of the second coupler O.
Accordingly, not only is fluid communication established between the two hoses 10, H but so is full electrical connectivity through the mating terminals 34, 36, 44 and 46 and the hose conductors 20, 22.
The second end 12 and second coupler 28 of the extension hose 10 may be similarly interconnected with the end of the wand W. In this way both fluid communication and electrical connectivity are fully established between the canister housing C and the powerhead P. As a result, the operator may manipulate the switch S to energize both the suction generator G in the canister housing C and the motor M for tine rotary agitator A in the powerhead P. Thus dirt and debris are brushed and beaten from the nap of an underlying carpet by the rotary agitator A. That dirt and debris becomes entrained in the suction airstream produced by the suction generator G. As a result the dirt and debris is drawn through the wand W, the first extension hose 10 and the original equipment hose H into the dirt collection vessel V
in the canister housing C. That air is then passed over the motor of the suction generator G to cool the motor before being exhausted into the environment through the exhaust vents E. The vessel V may, of course, be a filter bag, a dirt cup or a cyclonic collection vessel.
Since the first and second couplers 26, 28 are standardized for interconnection, any number of extension hoses or sections 10 may be coupled together to provide a working hose of substantially any desired length. The design of the couplers 26, 28 ensures that full airstream fluid communication and electrical connectivity are maintained throughout the length of the working hose no matter how many extension hose sections 10 are connected together.
The foregoing description of the preferred embodiment of this invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. For example, while the electrified extension hose 10 described in detail above is a "stretch hose", the invention also includes non-stretch embodiments. Further, while illustrated for use with a canister vacuum cleaner, it should be appreciated that the extension hose 10 may also be used with an upright vacuum cleaner if desired.
The embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled. The drawings and preferred embodiment do not and are not intended to limit the ordinary meaning of the claims and their fair and broad interpretation in any way.
