Abstract
Abstract A building construction assembly including a first elongated structural member having a longitudinally disposed keyway having a base wall and a pair of sidewalls projecting from the base wall. Means providing an elongated restricted throat keyway opening. A second elongated structural member having a longitudinal axis disposed generally transversely with respect to the longitudinal axis of the first elongated structural member. The second elongated structural member having a locking channel having a bottom wall, a front wall and a rear wall. The second elongated structural member disposed with its locking channel in aligned relationship with respect to an end opening of the keyway. A locking key having a first portion extending into the keyway and a second portion extending into and in engagement with the locking channel. Means resisting undesired movement of the key into the keyway sufficiently far to permit removal of the second key portion from the locking channel. A condensate gutter element may be secured within the locking channel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
265 words
A building construction assembly comprising a first elongated structural member having a longitudinally disposed keyway defined by a base wall and a pair of sidewalls projecting from said base wall, means on at least one of said sidewalls establishing a restricted throat keyway opening, a second elongated structural member having a longitudinal axis disposed generally transversely with respect to the longitudinal axis of said first elongated structural member, said second elongated structural member having a longitudinally disposed locking channel having a bottom wall, a front wall and a rear wall, said second elongated structural member disposed with its locking channel in aligned relationship with respect to an end opening of said keyway, a locking key having a first portion extending into said keyway, said locking key having a second portion extending into and in locking engagement with said locking channel, said locking key second portion is disposed in engagement with said locking channel rear wall, said locking channel rear wall having a rear channel surface which slopes rearwardly as it extends away from said channel bottom wall, said locking key second portion having a rear key surface slope which is generally complementary to said rear channel surface slope, said rear channel surface and said rear key surface in frictional interengagement which resists relative separating movement between said first and second elongated structural members, and means resisting longitudinal movement of said key into said keyway sufficiently far to permit removal of said second key portion from locking engagement within said locking channel, whereby said first and second elongated structural members are effectively secured to each other.
Claim 2
Dependent Claim
265 words
A building construction assembly comprising a first elongated structural member having a longitudinally disposed keyway defined by a base wall and a pair of sidewalls projecting from said base wall, means on at least one of said sidewalls establishing a restricted throat keyway opening, a second elongated structural member having a longitudinal axis disposed generally transversely with respect to the longitudinal axis of said first elongated structural member, said second elongated structural member having a longitudinally disposed locking channel having a bottom wall, a front wall and a rear wall, said second elongated structural member disposed with its locking channel in aligned relationship with respect to an end opening of said keyway, a locking key having a first portion extending into said keyway, said locking key having a second portion extending into and in locking engagement with said locking channel, said locking key second portion is disposed in engagement with said locking channel rear wall, said locking channel rear wall having a rear channel surface which slopes rearwardly as it extends away from said channel bottom wall, said locking key second portion having a rear key surface slope which is generally complementary to said rear channel surface slope, said rear channel surface and said rear key surface in frictional interengagement which resists relative separating movement between said first and second elongated structural members, and means resisting longitudinal movement of said key into said keyway sufficiently far to permit removal of said second key portion from locking engagement within said locking channel, whereby said first and second elongated structural members are effectively secured to each other.
Claim 3
Dependent Claim
29 words
The building construction assembly of claim 1 including said first elongated structural member is a substantially vertical member, and said second elongated structural member is a substantially horizontal member.
Claim 4
Dependent Claim
40 words
The building construction assembly of claim 2 including said keyway throat defining means on said sidewalls including a flange on each said sidewall extending transversely inwardly therefrom, and said means resisting longitudinal movement of said key including keyway restricting means.
Claim 5
Dependent Claim
56 words
The building construction assembly of claim 3 including said keyway restricting means including a deformed portion of at least one of said transversely inwardly directed keyway throat defining flanges, and said keyway restricting flange portion having a thickness less than the average thickness of the remainder of the sidewall from which said throat defining flange projects.
Claim 6
Dependent Claim
68 words
The building construction assembly of claim 2 including said locking key first portion provided with a peripheral configuration generally similar to the configuration of said keyway but of reduced dimension with respect thereto, and resiliently compressed gasket means disposed intermediate at least one peripheral surface of said locking key first portion and an adjacent keyway wall, whereby undesired movement of said locking key within said keyway is resisted.
Claim 7
Dependent Claim
43 words
The building construction assembly of claim 2 including said locking key rear surface having a number of generally rearwardly projecting serrations in engagement with said locking channel rear surface, and said locking channel rear surface having a plurality of generally forwardly projecting serrations.
Claim 8
Dependent Claim
56 words
The building construction assembly of claim 2 including an upwardly open channel shaped condensate gutter secured within said locking channel, said condensate gutter having a base disposed in spaced overlying relationship with respect to said locking channel bottom wall, and saiD condensate gutter element originating adjacent said locking key and extending longitudinally along said locking channel.
Claim 9
Dependent Claim
72 words
The building construction assembly of claim 7 including said condensate gutter having a pair of gutter defining sidewalls extending upwardly from said gutter base, each said gutter defining sidewall terminating in an outwardly directed flange which is disposed exteriorly of said locking channel, and said condensate gutter having an end in communication with said vertical member to permit discharge of water from said gutter to said vertical member for ultimate discharge therefrom.
Claim 10
Dependent Claim
55 words
The building construction assembly of claim 2 including said vertical member has a forwardly facing wall with a portion thereof providing said keyway base wall, said keyway sidewalls projecting forwardly from said forwardly facing wall, and said vertical member having a longitudinal discontinuity disposed forwardly of said forwardly facing wall defining a forwardly open notch.
Claim 11
Dependent Claim
66 words
The building construction assembly of claim 9 including said vertical member has a single keyway, said horizontal member extending into said notch with said locking channel being upwardly open and in aligned underlying relationship with respect to an end opening of said keyway, said horizontal member extends continuously across said vertical member notch, and a single locking key secures said vertical member to said horizontal member.
Claim 12
Dependent Claim
