Abstract
Abstract A tether band for flexible conduits, such as hydraulic hoses, which provide fluid communication between machine parts having relative movement, includes a wide metal band having an anchor unit on at least one end thereof for securing it to a rigid fitting on one end of a conduit and a plurality of brackets disposed in spaced relationship along the band for interconnecting the band with a flexible conduit arranged in a corresponding arcuate relationship with the band to restrict the undesirable lateral movements of the flexible conduit parallel to the width of the band without interference of common movements normal thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
A tether band for restraining flexible hydraulic hoses having hose fittings attached to their opposite ends for connecting them to machine components having relative movement comprising: an elongated metal band having a width substantially greater than its thickness, said metal band having a plurality of spaced notches along its length and flexible along its longitudinal axis normal to its width; an anchor means on at lest one end of said metal band for attaching it to a hose fitting of one of such hoses so said band is attached to onE of the components through a hose fitting so it can be removed with such hoses as a unit without being disconnected from such fitting; and a plurality of bracket means disposed in spaced relationship along the length of said band in spaced notches operable to prevent longitudinal movement of said bracket means along said band with at least one of said bracket means located adjacent to each end of said band any remaining bracket means disposed intermediately thereof, each of said bracket means including means attaching it in its notch which prevents rotation of said bracket about the longitudinal axis of said band.
Claim 2
Dependent Claim
194 words
A tether band for restraining flexible hydraulic hoses having hose fittings attached to their opposite ends for connecting them to machine components having relative movement comprising: an elongated metal band having a width substantially greater than its thickness, said metal band having a plurality of spaced notches along its length and flexible along its longitudinal axis normal to its width; an anchor means on at lest one end of said metal band for attaching it to a hose fitting of one of such hoses so said band is attached to onE of the components through a hose fitting so it can be removed with such hoses as a unit without being disconnected from such fitting; and a plurality of bracket means disposed in spaced relationship along the length of said band in spaced notches operable to prevent longitudinal movement of said bracket means along said band with at least one of said bracket means located adjacent to each end of said band any remaining bracket means disposed intermediately thereof, each of said bracket means including means attaching it in its notch which prevents rotation of said bracket about the longitudinal axis of said band.
Claim 3
Dependent Claim
53 words
The tether band as defined in claim 1 wherein the anchor means includes a U-bolt and a spacer whereby the metal band can be attached to a circular portion of a hose fitting and so its longitudinal axis is parallel to the cylindrical surfaces of said hose fitting to which it is attached.
Claim 4
Dependent Claim
26 words
The tether band as defined in claim 1 wherein each bracket means includes an elastomer insert with apertures to accept hydraulic hoses to be retained thereby.
Claim 5
Dependent Claim
35 words
The tether band as defined in claim 1 wherein both ends of the metal band include an anchor means for respectively attaching its ends to hose fittings at opposite ends of a hose tethered thereby.
Claim 6
Dependent Claim
84 words
The tether band as defined in claim 1 wherein the bracket means are formed of a pair of rigid straps that form a cage around a hose when attached to the metal band to allow limited movement of said hose within said bracket means thereby allowing radial growth and limited axial movement of said hose within the bracket means as a result of pressure changes within the hose and relative movement caused by vertical adjustment of machine components between which said hose is attached.
