Abstract
A central vacuum cleaning system includes a locking collar mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends therefrom for cleaning an adjacent area. A pair of O-rings within the collar frictionally retains a handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on the collar automatically locks the hose in a selected extended position when manually pulled from the collar by a locking finger engaging an adjacent section of the hose. An electric switch on the collar enables a user to actuate the vacuum supply source. A mounting bracket enables the collar to be mounted at various locations in the structure and a ring formed on the collar enables the collar to be rotated to a desired position on the mounting bracket.
