Abstract

Hydraulic hoses coupled between the tractor and trailer units of an articulated vehicle are connected to each of the units by a swivel joint to permit the hydraulic hoses to swivel at the point of connection to the respective tractor and trailer units. The hydraulic hoses are individually positioned within separators to separate the hydraulic hoses and position them in a predetermined manner relative to forming a hose bundle. Each of the hydraulic hose supporting separators is positioned on a steel spring bow to control the shape of the hose bundle, with each end of the spring bow terminating in a coil spring at the point of connection with the tractor and trailer units. A support frame, preferably joined to the trailer unit, retains the hose bundle in a predetermined position to provide vertical stability and a spiral plastic or rubber outer wrap encircles the hose bundle to protect and keep the bundle together. In this manner, the hydraulic hoses are protected, and can accommodate the relative articulation and roll between the tractor and trailer units while the positioning of the bundles is controlled to eliminate or minimize any twisting action imposed thereon.

Claims

1. A support system for controlling the position and movement of a flexible connector connected at a first end to a first member and at a second end to a second member, said first and second members moveable relative to each other, comprising:

a flexible connector having a first end and a second end;

a first member connected to said first end of said flexible connector;

a second member connected to said second end of said flexible connector;

a spring bow supporting said flexible connector and having a first end and a second end;

said first end of said spring bow connected to said first member and said second end of said spring bow connected to said second member; and

said first and second ends of said spring bow each including a spring forming the connection to said respective first and second members.

2. The support system of claim 1 further including at least one flexible connector separator carried by said spring bow for bundling a plurality of flexible connectors thereto.

3. The support system of claim 2 wherein said flexible connector comprises a plurality of hydraulic hoses.

4. The support system of claim 3 further including a protective covering encircling said plurality of hydraulic hoses, said spring bow and said flexible connector separator.

5. The support system of claim 4 wherein at least one of said hydraulic hoses is connected to at least one of said first and second members by a swivel coupling.

6. The support system of claim 4 including three flexible connector separators, an uppermost flexible connector secured to said spring bow and two flexible connector separators carried by said spring bow and moveable relative thereto.

7. The support system of claim 1 wherein each of said springs is formed with a terminal portion for joining said spring bow to said first and second members.

8. The support system of claim 1 further including a support frame carried by one of said first and second members in a position to engage said flexible connector and said spring bow for retaining said flexible connector and said spring bow in a predetermined position.

9. A support system for controlling the position and movement of a plurality of flexible hydraulic hoses connected at one end to a tractor unit and connected at another end to a trailer unit, comprising:

a plurality of hydraulic hoses, each of said hydraulic hoses connected at a first end to a tractor unit and connected at a second end to a trailer unit;

at least one of said plurality of hydraulic hoses having a swivel connection at one of the ends thereof for coupling to one of said tractor or trailer units;

a spring bow for supporting said plurality of hydraulic hoses, said spring bow having at least one spring at one end thereof connecting said spring bow to one of said tractor or trailer units;

a plurality of hydraulic hose separators carried by said spring bow and supporting said plurality of hydraulic hoses forming a hydraulic hose bundle; and

a protective covering positioned about said hydraulic hose bundle.

10. The support system of claim 9 further including a support frame carried by one of said tractor or trailer units and positioned to engage said hydraulic hose bundle for supporting said hydraulic hose bundle in a predetermined position.

11. The support system of claim 10 wherein said support frame including releasable elastomeric fasteners for engaging said hydraulic hose bundle and securing said hydraulic hose bundle to said support frame.
