Radio frequency controlled central vacuum endfitting

Abstract

The present invention includes a flexible hose with at least two end fitting. The first end fitting is inserted into the wall valve of the central vacuum cleaner system. The first end fitting is generally rectangular in shape and may have a kill switch located thereto. The first end fitting may be used as a receiver. In addition the first end fitting may include a generally cylindrical coupling member. The coupling member may include at least one contact member. The contact member may be located on the outer circumferential surface of the coupling member. The second end fitting may be shaped like a handle for controlling the power head. In addition the second end fitting may be used as the transmitter. Located on the second end fitting may be an indicator light that lets the user know if the handle is transmitting to the first end fitting.

Description

[0001] This application claims priority on U.S. Application Ser. No. 60 / 794,023 filed Apr. 21, 2006, the disclosures of which are incorporated herein by reference.FIELD OF INVENTION [0002] The present invention relates to improvements in vacuum systems. More specifically, the present invention relates to a vacuum handle having a radio frequency transmitter and an associated receiver for operating a vacuum system, in particular a vacuum system such as a central vacuum system. The vacuum handle communicates with the system through a receiver via a radio frequency remote control. The receiver may be an endfitting on the hose itself or on the system or elsewhere. BACKGROUND OF THE INVENTION [0003] A central vacuum power unit sits in an out-of the-way area such as your garage, basement, or utility room. Wall inlet valves are then installed in various locations throughout the home and connected to the power unit through tubing. Generally, the tubing can be run through the attic, basement ...

AI Technical Summary

Benefits of technology

"The present invention is a control system for a vacuum cleaner that includes a vacuum handle with a radio frequency (RF) transmitter. The handle has a battery and a transmitter that sends an RF signal to a receiver. The receiver has an antenna that receives the RF signal and sends it to a system control circuit. The system control circuit generates a control signal that is sent to a relay to turn on the vacuum cleaner. The handle has a button that activates the RF transmitter when pressed. The invention allows for remote operation of the central vacuum system without direct connections back to the main power unit. It also includes an improved kill switch and a universal adapter for different types of wall valves. The invention also eliminates the need for heavy flexible hoses and provides better battery life."

Problems solved by technology

In the prior art previously citied, Harkonen et al, there are present significant drawbacks.

The battery and sound generator combination occupy a significant volume within the handle of the wand, making the wand heavier, larger, and more unwieldy.

However, the end fitting, because its circuit does physical work by holding power to the relay, therefore power preservation is critical.

Perhaps the greatest difficulty with the method of Harkonen lies in the means for stopping the vacuum cleaner.

Further, items too large to pass conveniently through the tubing may be inadvertently sucked into the vacuum head, thereby turning it off.
