Abstract
Abstract A tube mounting assembly as, for example, to connect the hose connection tubes of a pair of hoses to a refrigerant compressor used in a vehicle air conditioning system, the compressor having inlet and outlet openings therein to receive the ends of the hose tubes. Each tube is connected at one end to a hose and is provided at its opposite end with an upset annular bead adjacent to its free end which is of a suitable length to act as a pilot tube portion for insertion into an opening in the compressor, the annular bead on the tube being sandwiched between the legs of a fold-around clamp against which an O-ring seal encircling the free end of the tube is seated. A pair of slotted tube brackets are mounted in interlocking relationship with each other about each tube on the opposite side of the fold-around clamp from the O-ring seal, the brackets being apertured to receive at least one hold-down fastener whereby this assembly can be secured to the compressor with each O-ring seal being sandwiched between a foldaround clamp and the housing of the compressor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
344 words
A tube mounting assembly for securing N number of tubes to an accessory housing, the accessory housing having an N number of bored passages to receive the tubes, each of the tubes having an annular upset bead adjacent one end of the tube with a pilot tube portion extending therefrom for insertion into one of the bored passages, said tube mounting assembly including a fold-over clamp for each tube having a first leg and a second leg connected at one end by an integral bight, said first leg having an aperture therein to receive the pilot tube portion of a tube and the second leg having a slot therein of a size to slidably receive the tube, said fold-over clamp being secured to a tube with the pilot tube portion of a tube inserted into the aperture in said first leg and with the bead of the tube securely sandwiched between said first leg and said second leg, an O-ring positioned to encircle the pilot tube portion of each tube in abutment against said first leg of said fold-over clamp associated with the tube and, a split flange connector consisting of two brackets of identical shape, said brackets each having an N number of tube receiving slot openings extending from one side thereof to receive said N number of tubes, said brackets being positioned in opposed, overlapping, fixed relation to each other with the N number of tubes positioned in said slots whereby the tubes are entrapped between said pair of brackets, said brackets being positioned on the opposite side of each fold-over clamp from said O-ring associated therewith, each said fold-over clamp further including positioning tab means for engagement with said brackets to lock each said fold-over clamp and therefore a tube associated therewith against rotation relative to said brackets, said brackets having aperture means therethrough to receive fastener means for securing said brackets to the accessory housing with said clamp and O-ring sandwiched therebetween with said O-ring in sealing engagement with said first leg of the fold-over clamp and the accessory housing.
Claim 2
Dependent Claim
344 words
A tube mounting assembly for securing N number of tubes to an accessory housing, the accessory housing having an N number of bored passages to receive the tubes, each of the tubes having an annular upset bead adjacent one end of the tube with a pilot tube portion extending therefrom for insertion into one of the bored passages, said tube mounting assembly including a fold-over clamp for each tube having a first leg and a second leg connected at one end by an integral bight, said first leg having an aperture therein to receive the pilot tube portion of a tube and the second leg having a slot therein of a size to slidably receive the tube, said fold-over clamp being secured to a tube with the pilot tube portion of a tube inserted into the aperture in said first leg and with the bead of the tube securely sandwiched between said first leg and said second leg, an O-ring positioned to encircle the pilot tube portion of each tube in abutment against said first leg of said fold-over clamp associated with the tube and, a split flange connector consisting of two brackets of identical shape, said brackets each having an N number of tube receiving slot openings extending from one side thereof to receive said N number of tubes, said brackets being positioned in opposed, overlapping, fixed relation to each other with the N number of tubes positioned in said slots whereby the tubes are entrapped between said pair of brackets, said brackets being positioned on the opposite side of each fold-over clamp from said O-ring associated therewith, each said fold-over clamp further including positioning tab means for engagement with said brackets to lock each said fold-over clamp and therefore a tube associated therewith against rotation relative to said brackets, said brackets having aperture means therethrough to receive fastener means for securing said brackets to the accessory housing with said clamp and O-ring sandwiched therebetween with said O-ring in sealing engagement with said first leg of the fold-over clamp and the accessory housing.
Claim 3
Dependent Claim
128 words
A tube mounting assembly according to claim 1 wherein the N number of tubes is two, and wherein each of said brackets consists of a flat mounting flange with an integral upstanding flange at one longitudinal edge thereof, said flat mounting flange having two spaced apart parallel tube receiving slot openings extending from the oppoSite longitudinal edge thereof and having a fastener slot opening intermediate said tube receiving slot openings, each said mounting flange having a lock tab extending from opposite transverse sides thereof, and wherein said positioning tab means on each said fold-over clamp is a return bent tab integral with said second leg thereof at the end of said second leg opposite said bight, the said return bent tab being positioned to entrap said lock tab.
Claim 4
Dependent Claim
293 words
A tube mounting assembly for securing an N number of tubes to an accessory housing having an N number of bored passages to receive the tubes, each of the tubes being of the type formed with an external annular bead and a cylindrical pilot portion extending from one side of said bead to a free end thereof for insertion into a bored passage in the accessory housing, said tube mounting assembly including a fold-over clamp for each tube of the N number of tubes, each said fold-over clamp including a first apertured leg and a second bifurcated leg connected to each other at one end by an integral bight, said first apertured leg encircling the pilot tube portion of a tube with the apertured leg in abutment against the bead to provide a seat for an O-ring, the second bifurcated leg partly encircling the tube on the opposite side of the bead with the bead securely sandwiched between said first apertured leg and said second bifurcated leg to prevent rotation of the tube relative to said fold-over clamp, an O-ring positioned to encircle the pilot tube portion in abutment against said first apertured leg and, a split flange connector consisting of two brackets of identical shape secured together in interlocking relationship about said tubes, each said bracket having an N number of slot openings extending from one side thereof to receive said tubes and at least one slot opening to receive a fastener whereby said brackets can be secured to an accessory housing, said brackets encircling said tubes adjacent said second bifurcated leg of each said fold-over clamp, and positioning means associated with each of said fold-over clamps and with said brackets for retaining said fold-over clamps against rotation relative to said brackets.
Claim 5
Dependent Claim
