Extendible hose assembly for service truck

Abstract

An extendible hose assembly for extending from a .Iadd.holding tank of a .Iaddend.portable toilet service truck or similar service vehicle to a portable toilet or similar tank to be serviced. The assembly has two rotational hinges for horizontal movement of hoses and at least one hinge allowing vertical movement of hoses. The combination of hinges allows the hoses to be extended for use in any direction from the .Iadd.tank carried by the .Iaddend.service vehicle .Iadd.and to be compactly folded in substantially "side-by-side" relation longitudinally along the length of the holding tank.Iaddend..

What is claimed is: 
     
       1. A portable extendible hose and support assembly mountable on and connectable to a tank located on a service vehicle, comprising in combination: a .[.relative.]. .Iadd.relatively .Iaddend.short rigid hose,   a first hinge comprising a generally U-shaped bracket defined by legs attached to the tank, and a first tubular member having a first axial center supported between the legs of the U-shaped bracket, with a bolt extending vertically through said legs and the axial center of the tubular member, and having a vertical axis,   means attaching the tubular member to the short rigid hose,   a second hinge comprising a vertically disposed second pin and a second tubular member, with the pin extending through the second axial center of the second tubular member, said second pin having upper and lower ends and a vertical axis,   a third hinge comprising a horizontally disposed pin having ends and attached to the lower end of the second pin, with two rotatable legs rotatably attached to the ends of said horizontal pin, said horizontal pin defining a horizontal axis,   a combination of serially connected hoses defining hose portions,   said first hinge supporting said combination on the tank of the vehicle and allowing horizontal swingable movement of the combination of serially connected hoses about the vertical axis of the hinge,   said second hinge being horizontally spaced from and supported by said first hinge, and allowing horizontal swingable movement of a portion of said combination of serially connected hoses about the vertical axis of the second hinge,   said third hinge permitting vertical movement of said hose portion of the combination of hoses about the horizontal axis of the horizontal pin,   said combination of hoses comprising:   a first elongated rigid hose having ends and mounted on the first hinge, and connected in fluid communication with the short rigid hose, said elongated hose extending to the second hinge such that the ends of the first elongated hose are located adjacent the first and second hinges,   means connecting the end of the first elongated rigid hose adjacent the second hinge to the second hinge,   a second elongated rigid hose having ends, one of which is attached to the third hinge by the rotatable lugs, the end supported by the third hinge lying adjacent the end of the first rigid hose that is adjacent the second hinge,   a flexible hose serially connecting the end of the first elongated rigid hose to the end of the second elongated rigid hose at the second hinge, and   an elongated flexible hose having one end connected to the end of the second rigid hose remote from the second hinge, with the other end of the elongated flexible hose being free to be maneuvered as desired.   
     
     
       2. An economical hinge arrangement for swinging serially connected, elongated hoses about the axes of at least two hinges, comprising: a first hinge comprising a generally U-shaped bracket defined by legs, and a first tubular member having a first axial center and supported between the legs of the U-shaped bracket, with a first pin means extending through said legs and through the axial center of the first tubular member, said first hinge defining a first axis, and   a second hinge comprising a second pin and a second tubular member having a second axial center, with a second pin extending through the second axial center of the second tubular member, said second hinge defining a second axis,   at least a first and a second elongated rigid hose each having ends, and being serially connected together,   said first hinge supporting said hoses and allowing swingable movement of the hoses about the first axis of the hinge,   said second hinge being spaced from and supported by said first hinge, and allowing swingable movement of the second hose about the second axis of the second hinge,   said first elongated hose being mounted on the first hinge, and extending to the second hinge such that the ends of the first elongated hose are located adjacent the first and second hinges,   means connecting said end of the first rigid hose adjacent said second hinge to the second hinge,   said second elongated rigid hose having one end attached to said second hinge, and lying adjacent the end of said first rigid hose that is adjacent the second hinge, and   a flexible hose serially connecting the ends of said rigid hoses together. .Iadd.   
     
     
       3.  In combination, a manually extendible hose assembly and a tank carried on a service vehicle, said tank having a top, a bottom, and first and second substantially vertical sides, said hose assembly disposed in communication with the interior of said tank and for transportation by said service vehicle comprising: a first support means mounted on said first substantially vertical side and adjacent to a first end of said tank;   at least first and second elongated rigid hoses connected in serial, pivoted relation, each of said at least first and second rigid hoses having first and second ends, with said first end of the first hose of said at least first and second rigid hoses disposed in communication with said interior of said tank and pivotally mounted to said first support means for horizontal movement in a first horizontal plane against and away from said first substantially vertical side of said tank;   a second support means disposed between the first and second rigid hoses of said at least first and second rigid hoses, said second support means pivotally connected to said second end of the first hose of said at least first and second hoses and to said first end of said second rigid hose of said at least first and second hoses for movement thereof in a second horizontal plane against and away from said first substantially vertical side of said tank; and   means for securing said at least first and second rigid hoses in vertically spaced, stored relation against said first substantially vertical side of said tank responsive to movement in said first and second horizontal planes of said at least first and second rigid hoses against said first substantially vertical side of said tank. .Iaddend. .Iadd.   
     
     
       4.  An assembly as set forth in claim 3 including a first flexible hose connecting the second end of said first rigid hose of said at least first and second rigid hoses to the first end of said second hose of said at least first and second rigid hoses. .Iaddend. .Iadd.5. An assembly as set forth in claim 4 including resilient support means extending between said second support means and said second rigid hose of said at least first and second hoses for support of said second rigid hose of said at least first and second hoses in said extended relation and for limiting vertical movement of said second rigid hose of said at least first and second rigid hoses. .Iaddend. .Iadd.6. An assembly as set forth in claim 5 including a second flexible hose connected to said second end of said second rigid hose of said at least first and second rigid hoses and disposed for vertically folded side-by-side, stored relation with said second rigid hose of said at least first and second rigid hoses longitudinally along the length of said first substantially vertical side of said tank, said second rigid hose of said at least first and second rigid hoses disposed for extended relation from said first rigid hose of said at least first and second rigid hoses. .Iaddend. .Iadd.7. An assembly as set forth in claim 6 wherein said second flexible hose is provided with first and second ends, said first end being connected to said second end of said second rigid hose of said at least first and second rigid hoses, a valve and nozzle assembly connected to said second end of said second flexible hose, and means for securing said second flexible hose to said first substantially vertical side of said tank. .Iaddend.
