Central vacuum system universal hose end

Abstract

A universal hose ending fitting for connecting central vacuum system wall valves and cleaning attachment hose ends. Wall valves and hose ends provided by various manufacturers within the central vacuum industry are commonly mismatched and do not provide a snug, secure connection. The disclosed fitting is a sleeve that attaches to the hose end and upon insertion into the wall valve, provides the necessary secure fit. The disclosed embodiment is of a sleeve having flex to accommodate different size components.

1 . A vacuum hose fitting arrangement for central vacuum systems, the arrangement comprising: 
 a) a wall valve connected to a central vacuum system and having an inlet receptacle;    b) a vacuum hose having a second end connectible to cleaning attachments and a first end insertable into the wall valve inlet receptacle to complete a vacuum circuit, the fit between the vacuum hose first end and the wall valve being an imperfect fit; and    c) a sleeve fittable over the vacuum hose first end and having flex so as to provide a snug insertion fit of the vacuum hose first end into the inlet receptacle.    
   
   
       2 . The vacuum hose fitting arrangement set forth in  claim 1  wherein the sleeve is a rigid material having flex leaves.  
   
   
       3 . A universal fitting sleeve connectible between a central vacuum system wall valve having an inlet receptacle and vacuum hose end which would otherwise have an imperfect fit upon insertion into the wall valve inlet receptacle, the sleeve fittable over the vacuum hose end and having flex to provide a snug fit of the vacuum hose end into the inlet receptacle.  
   
   
       4 . A universal fitting sleeve connectible between a central vacuum system wall valve having an inlet receptacle and vacuum hose end which would otherwise have an imperfect fit upon insertion into the wall valve inlet receptacle, the sleeve being of a substantially rigid material having flex portions to provide a snug fit of the vacuum hose end into the inlet receptacle.
