Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A tube support assembly for securing loops of wound fin tubing in an inclined configuration which comprises: a support member having a partition end portion an opening and a back portion extending at an inclined angle relative to the axis of said opening in said end portion, and at least one extension portion spaced from said partition end portion and defining a rod slot having means to snap fit a rod therein, said partition end portion and said at least one extension portion extending from the same side of said back portion; and tubular support rod sized to extend through the opening in the partition end portion and to snap fit into the rod slot of said at least one extension portion and includes an end portion which extends through the opening in the partition end portion and a body portion angled from the end portion and being generally parallel to the back portion of the support member when snap fit into said rod slot, the loops of tubing being secured between the tubular support rod and the support member.
Claim 2
Dependent Claim
180 words
A tube support assembly for securing loops of wound fin tubing in an inclined configuration which comprises: a support member having a partition end portion an opening and a back portion extending at an inclined angle relative to the axis of said opening in said end portion, and at least one extension portion spaced from said partition end portion and defining a rod slot having means to snap fit a rod therein, said partition end portion and said at least one extension portion extending from the same side of said back portion; and tubular support rod sized to extend through the opening in the partition end portion and to snap fit into the rod slot of said at least one extension portion and includes an end portion which extends through the opening in the partition end portion and a body portion angled from the end portion and being generally parallel to the back portion of the support member when snap fit into said rod slot, the loops of tubing being secured between the tubular support rod and the support member.
Claim 3
Dependent Claim
36 words
The apparatus as set forth in claim 1 wherein the support member further comprises a tube securing portion having extending securing projections defining angled openings for the receipt of the individual loops of wound fin tubing.
Claim 4
Dependent Claim
45 words
The apparatus as set forth in claim 1 wherein said at least one extension portion further comprises coacting projections forming said means to snap fit which partially define the rod slot and which are spaced apart less than the diameter of the tubular support rod.
Claim 5
Dependent Claim
23 words
The apparatus as set forth in claim 1 wherein the partition end portion is angled from the back portion of the support member.
Claim 6
Dependent Claim
45 words
The apparatus as set forth in claim 4 wherein the tubular support rod end portion is threaded such that the tube support assembly may be mounted to a vertical member via engagement of a fastener with the threaded end portion of the tubular support rod.
Claim 7
Dependent Claim
27 words
The apparatus as set forth in claim 4 wherein the tubular support rod further comprises a shoulder extending outwardly therefrom to abut against the partition end portion.
