Abstract
Abstract A tube-to-plate connection includes a plate defining an aperture where the tube is to be attached to the plate, the portion of the plate surrounding the aperture including a flange extending away from the plane of the plate and providing, at its distal extent, a lip which projects radially inwardly toward the axis of the aperture. The end of the tube lies generally against the lip to prevent movement of the tube longitudinally further through the plate. The flange includes an opening for receiving a radially deformed portion of the tube side wall adjacent the end of the tube to prevent rotation of the tube in the plate. The flange and tube end include portions adjacent the lip which are flared to prevent movement of the tube longitudinally out of engagement with the plate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
177 words
A tube-to-plate connection comprising means on a plate defining an aperture where a tube is to be attached to the plate, the region of the plate surrounding the aperture including a flange for receiving the end of the tube, the flange including a proximal end at its junction with the plate, a first portion extending away from the plane of the plate, a second lip portion extending generally radially toward the axis of the aperture, and a third portion extending toward the plane of the plate at the distal end of the flange, the tube including a side wall portion lying adjacent the flange, the flange including an opening which extends longitudinally of the aperture axis partly across the first portion, across the second portion and across the third portion, the tube side wall being deformed to project into the opening to prevent rotation of the tube with respect to the plate and longitudinal movement of the tube in the aperture, the tube end projecting into the aperture into contact with the lip portion of the flange.
Claim 2
Dependent Claim
177 words
A tube-to-plate connection comprising means on a plate defining an aperture where a tube is to be attached to the plate, the region of the plate surrounding the aperture including a flange for receiving the end of the tube, the flange including a proximal end at its junction with the plate, a first portion extending away from the plane of the plate, a second lip portion extending generally radially toward the axis of the aperture, and a third portion extending toward the plane of the plate at the distal end of the flange, the tube including a side wall portion lying adjacent the flange, the flange including an opening which extends longitudinally of the aperture axis partly across the first portion, across the second portion and across the third portion, the tube side wall being deformed to project into the opening to prevent rotation of the tube with respect to the plate and longitudinal movement of the tube in the aperture, the tube end projecting into the aperture into contact with the lip portion of the flange.
Claim 3
Dependent Claim
21 words
The tube-to-plate connection of claim 1 wherein the opening comprises a slot extending generally radially of the axis of the aperture.
Claim 4
Dependent Claim
20 words
The tube-to-plate connection of claim 2 including a plurality of such slots spaced apart about the perimeter of the aperture.
Claim 5
Dependent Claim
24 words
The tube-to-plate connection of claim 3 wherein there are four such slots and they are substantially equally spaced about the perimeter of the aperture.
Claim 6
Dependent Claim
15 words
A tube-to-plate connection according to claim 1 wherein the aperture is generally circular in shape.
Claim 7
Dependent Claim
35 words
A tube-to-plate connection according to claim 1 wherein the flange and the tube side wall adjacent the flange are both flared radially outwardly further to prevent axial movement of the tube back through the aperture.
Claim 8
Dependent Claim
172 words
A tube-to-plate connection comprising means on a plate defining an aperture where the end of a tube is to be attached to the plate, the region of the plate surrounding the aperture including a flange for receiving the end of the tube, the flange including a proximal end at its junction with the plate a first portion extending away from the plane of the plate, a second lip portion extending generally radially toward the axis of the aperture, and a third portion extending generally back toward the plane of the plate to define an annular groove for receiving the tube end, the flange including a slot-shaped opening which extends longitudinally of the aperture axis at least partly across the first portion, across the second portion and across the third portion, the tube side wall being deformed to project into the opening to prevent rotation of the tube with respect to the plate and longitudinal movement of the tube in the aperture, the tube end projecting into the aperture to contact the lip.
Claim 9
Dependent Claim
172 words
A tube-to-plate connection comprising means on a plate defining an aperture where the end of a tube is to be attached to the plate, the region of the plate surrounding the aperture including a flange for receiving the end of the tube, the flange including a proximal end at its junction with the plate a first portion extending away from the plane of the plate, a second lip portion extending generally radially toward the axis of the aperture, and a third portion extending generally back toward the plane of the plate to define an annular groove for receiving the tube end, the flange including a slot-shaped opening which extends longitudinally of the aperture axis at least partly across the first portion, across the second portion and across the third portion, the tube side wall being deformed to project into the opening to prevent rotation of the tube with respect to the plate and longitudinal movement of the tube in the aperture, the tube end projecting into the aperture to contact the lip.
Claim 10
Dependent Claim
21 words
The tube-to-plate connection of claim 7 including a plurality of such slot-shaped openings spaced apart about the perimeter of the aperture.
Claim 11
Dependent Claim
25 words
The tube-to-plate connection of claim 8 wherein there are four such slot-shaped openings and they are substantially equally spaced about the perimeter of the aperture.
Claim 12
Dependent Claim
15 words
A tube-to-plate connection according to claim 7 wherein the aperture is generally circular in shape.
Claim 13
Dependent Claim
35 words
A tube-to-plate connection according to claim 7 wherein the flange and the tube side wall adjacent the flange are both flared radially outwardly further to prevent axial movement of the tube back through the aperture.
