Abstract
Abstract Waste pipe support apparatus comprises two nested, trough type, semi-cylindrical tubular members which are telescopically slideable relative to each other for providing the apparatus with required extensibility and contractibility. A bail-type support leg structure elevates one end of the apparatus relative to the other end and the local terrain. Bracket stops limit the pivotable movement of the support leg structure in its operative mode so as to provide stability therefor, and a nut-and-bolt/slot mechanism is provided within the trough members for providing infinite telescopic adjustment capabilities to the apparatus in the longitudinal direction. Guide means is also defined between the trough members for facilitating the movement and retention of one member relative to the other member during the aforenoted longitudinal adjustment operation. The bracket structure of the apparatus also provides for elevational adjustment of the bail leg structure.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
238 words
Apparatus for supporting a waste pipe normally interconnecting a vehicle waste drain pipe with a permanent camp site sewage head, comprising: a first support member for supporting a first portion of said waste pipe; a second support member for supporting a second portion of said waste pipe, said second member being slideably disposed within said first support member; leg means pivotably mounted, within a longitudinally extending plane, relative to said first support member so as to be disposed either in an operative or storage position and for supporting said first support member in an elevated position relative to the local terrain upon which said apparatus is to be disposed when said leg means is disposed in said operative position; bracket means fixedly secured to said first support member; said leg means being pivotably mounted within said bracket means; first means defined within said bracket means for selectively mounting said leg means within any one of a multiplicity of positions within said bracket means so as to selectively permit elevational adjustment of said leg means relative to said apparatus; and second means fixedly secured within said bracket means and projecting laterally outwardly therefrom so as to intercept said pivotable leg means within said longitudinally extending plane and thereby block the pivotable movement of said leg means within said longitudinal plane beyond which point said leg means cannot be moved, said point defining said operative position for said leg means.
Claim 2
Dependent Claim
238 words
Apparatus for supporting a waste pipe normally interconnecting a vehicle waste drain pipe with a permanent camp site sewage head, comprising: a first support member for supporting a first portion of said waste pipe; a second support member for supporting a second portion of said waste pipe, said second member being slideably disposed within said first support member; leg means pivotably mounted, within a longitudinally extending plane, relative to said first support member so as to be disposed either in an operative or storage position and for supporting said first support member in an elevated position relative to the local terrain upon which said apparatus is to be disposed when said leg means is disposed in said operative position; bracket means fixedly secured to said first support member; said leg means being pivotably mounted within said bracket means; first means defined within said bracket means for selectively mounting said leg means within any one of a multiplicity of positions within said bracket means so as to selectively permit elevational adjustment of said leg means relative to said apparatus; and second means fixedly secured within said bracket means and projecting laterally outwardly therefrom so as to intercept said pivotable leg means within said longitudinally extending plane and thereby block the pivotable movement of said leg means within said longitudinal plane beyond which point said leg means cannot be moved, said point defining said operative position for said leg means.
