Description
~2~
The present invention is concerned with a hub joint for coupling parts of tubular structures, in particular hose carts.
Hose carts are known in which the rotating drum designed to receive the hose is supported by a metal tubular structure formed of a base part optionally equipped with wheels and a top part functioning as the handling element.
The two tubular structural parts which are shaped like the letter U with appropriately located bends are joined together and to the revolving axle of the hose-winding drum at a pair of joints generally made of plastic material placed at the two sides of the drum. Each of said joints receives one end of each of the two parts of the tubular structure and the revolving hub of the drum perpendicularly thus creating a single supporting structure for the drum.
~ lub joints rnade of plas~ic rna~erial formed of two identical bodies placed side by side and each having a blind-hole seat to receive the end of a corresponding part of the tubular structure and a perpendicular through half-seat working in conjunction with the corresponding half-seat of the other body of the joint to receive the revolving drum hub are known at present.
The two joined ends of the tubular structure are thus nonaligned but parallel in a plane perpendicular to the drum rotation axis.
The object of the present invention is to provide a hub joint for coupling parts of tubular structures, in particular hose carts, which fulfills the same function as the above described joints but has a form which is simpler, more functional and easier to fabricate and assemble.
In accordance with the invention, this object is achived with a hub joint for coupling together elements of tubular structures and simultaneously mounting said elements B
~2~
ont:o a hub, said joint including:
an elongated body having a pair of opposite ends and a pa:ir of aligned axial blind bores in said opposite ends, respectively, for receiving ends of said elements to be coupled, said opposite ends of said body being threaded and having protruding locking tabs; and internally threaded locking ring-nuts, said ring-nuts being sized to be screwed onto said opposite ends and having inclined internal surfaces capable of acting on said locking tabs to force them inwardly into engagement with the tubular elements to be coupled;
wherein the body of said hub joint further comprises a central transverse bore sized to receive said hub.
The invention also provides a hose cart having a horizontal, rotatable hose drum with a pair of axially extending hubs at both ends; upper and lower, generally U-shaped tubular support elernents and two hub joints for coupling tog~ther said support e.Lements and simultaneously rotatably mounting said elements onto said hubs; wherein said hub joints each includes an elongated body having a pair of opposite ends and a pair of axial blind bores in said opposite ends, respectively, each of said bores respectively receiving one end of each of the U-shaped support elements, said opposite ends of said elongated body being threaded and having protruding locking tabs, each of said hub joint further including internally threaded locking ring-nuts used hole screwed on to said opposite ends and having inclined internal surfaces capable of acting on said locking tabs to force them inwardly into engagement with the corresponding ends of the U-shaped tubular elements, each of said hub joints further including a central transverse bore in which one of said hubs is mounted.
It is obviously a joint of extremely simple construction which can be assembled easily and quickly to ~4~
join parts of tubular structures and support a revolving hub such as that of the revolving drum of a hose cart.
An example of a practical embodiment of the hub joint in accordance with the invention is illustrated for S greater clarity in the annexed drawings in which:

Tw~ hub joints 1 are employed at the two sides of the revolving drum 17 to join together the free ends 6 and 5 of the two tubular structural parts 18 and 20 and act as supports for the end hubs 16 of the drum 17.
The present invention is concerned with a hub joint for coupling parts of tubular structures, in particular hose carts.
Hose carts are known in which the rotating drum designed to receive the hose is supported by a metal tubular structure formed of a base part optionally equipped with wheels and a top part functioning as the handling element.
