Adjustable venturi tube assembly for a gas barbecue grill

Abstract

A gas venturi tube assembly for a barbecue grill which can be utilized in a wide variety of gas barbecue grill burner elements and base portions. The venturi tube and the gas intake member telescope together in the usual manner. However, adjustable securing mechanisms are provided between the venturi tube and the gas intake member so that the gas intake member is in communication with the gas supply pipe irrespective of the placement of the burner element on the floor of the barbecue grill base. The adjustable securing mechanisms include a screw carried by the gas intake member for engagement with the venturi tube which can also have indented dimples or screw threads disposed in the venturi tube and gas intake member.

I claim: 
     
       1. An improved gas venturi tube assembly for a gas burner element comprising: a tubular member defining at least one lateral aperture;   an air regulator member slidably received by said tubular member at one end thereof to controllably cover said lateral aperture;   an opening defined by said regulator member adapted to receive a gas supply nozzle;   a gas intake conduit having an end for operative association with said burner element at one end and in telescoping relationship with said tubular member at the other end; and   adjustable securing means operatively associated with said tubular member and said intake conduit to secure said conduit and said tubular member in a fixed position.   
     
     
       2. The improved gas venturi tube assembly as defined in claim 1 further including length adjustment means operatively associated with said air regulator member and said tubular member. 
     
     
       3. The improved gas venturi tube assembly as defined in claim 2 wherein said air regulator member is defined by a rotatable collar and said length adjustment means is provided by an adjustment screw threadably positioned through said collar. 
     
     
       4. The improved gas venturi tube assembly as defined in claim 1 wherein said securing means is carried by said gas intake member. 
     
     
       5. The improved gas venturi tube assembly as defined in claim 1 wherein said adjustable securing means operatively associated with said tubular member and said gas intake conduit is defined by a set screw threadably carried by said gas intake conduit and indentations longitudinally disposed in said tubular member. 
     
     
       6. The improved gas venturi tube assembly as defined in claim 1 wherein said adjustable securing means operatively associated with said tubular member and said gas intake conduit is defined by external screw threads carried by said tubular member and complementary internal screw threads carried by said gas intake conduit for operative association. 
     
     
       7. The improved gas venturi tube assembly as defined in claim 6 wherein said internal screw threads carried by said gas intake conduit are defined by shear tabs. 
     
     
       8. The improved gas venturi tube assembly as defined in claim 1 wherein said adjustable securing means operatively associated with said tubular member and said gas intake conduit is defined by a screw member threadably carried by said gas intake conduit and positioned distal to the end operatively associated with said burner element. 
     
     
       9. The improved gas venturi tube assembly as defined in claims 5 and 8 wherein said screw is carried by gas intake conduit by an extension portion. 
     
     
       10. The improved gas venturi tube assembly as defined in claim 1 operatively connected to a gas barbecue grill unit. 
     
     
       11. An improved gas burner assembly for a gas barbecue grill having a floor comprising: a burner element;   a tubular member defining at least one lateral aperture;   an air regulator member slidably received by said tubular member at one end thereof to controllably cover said lateral aperture;   an opening defined by said regulator member adapted to receive a gas supply nozzle;   a gas intake conduit having an end for operative connection with said burner element at one end and in telescoping relationship with said tubular member at the other end;   adjustable securing means operatively associated with said tubular member and said intake conduit to secure said conduit and said tubular member in a fixed position;   said burner element including a hollow body member defining a central portion and at least two extending arm portions;   a plurality of apertures distributed over said body member; and   a leg member extending from each said arm portion and adjustable to contact said floor.   
     
     
       12. The burner element as defined in claim 11 wherein said leg member is defined by a longitudinal and angular portion extending from each arm portion and in a direction generally transverse of said connection with said gas intake conduit to provide adjustable contact with said floor. 
     
     
       13. The burner element as defined in claim 12 further including means to pivotally attach said leg members to said burner arm portion. .Iadd. 
     
     
       14.  An improved gas venturi tube assembly for a gas burner element comprising: a tubular member defining at least one lateral aperture;   an air regulatory member slidably received by said tubular member at one end thereof to controllably cover said lateral aperture;   an opening defined by said tubular member adapted to receive a gas supply nozzle;   a gas intake conduit having an end for operative association with said burner element at one end and in telescoping relationship with said tubular member at the other end; and   means constructed and arranged to limit movement of said gas intake conduit and said tubular member in said telescoping relationship. .Iaddend. .Iadd.15. The improved gas venturi tube assembly as defined in claim 14   
     
     
        operatively connected to a gas barbecue grill unit. .Iaddend. .Iadd.16. An improved gas burner assembly for a gas barbecue grill having a floor comprising: a burner element;   a tubular member defining at least one lateral aperture;   an air regulator member slidably received by said tubular member at one end thereof to controllably cover said lateral aperture;   an opening defined by said tubular member adapted to receive a gas supply nozzle;   a gas intake conduit having an end for operative connection with said burner element at one end and in telescoping relationship with said tubular member at the other end;   said burner element including a hollow body member defining a central portion and at least two extending arm portions;   a plurality of apertures distributed over said body member; and    a leg member extending from each said arm portion and adjustable to contact said floor. .Iaddend.
