Abstract
Abstract A trestle comprising plural similar structural elements releasably, movably joined to form a structure supported by releasably attached vertically adjustable legs upon a supporting surface therebeneath. The trestle is adapted particularly to support a flexible pipe such as the common trailer sewage disposal pipe. The elements may be moved relative each other to determine trestle angle and direction by adjustment of intercommunicating nut-bolt combinations, and the legs may be adjusted to determine vertical orientation of the trestle relative the supporting surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
An adjustably positionable trestle to support flexible pipe comprising, in combination: a plurality of trestle elements each having a medial body portion, with means for releasably attaching supporting legs and means of maintaining a pipe thereon, and with flanges oppositely extending, in the axial direction of a pipe to be supported, each flange having an arcuate outer periphery and means of releAsably fastening to an opposite cooperating flange of an adjacent element; means of releasably fastening the opposed flange of one adjacent trestle element to that of another wherein the oppositely extending fastening flanges are offset so that when in communication the upper surface of the trestle elements is substantially coplanar to continuously support a pipelike element over both the body part and the flange part of the trestle; and a plurality of adjustably extensible legs adapted to be releasably carried by the trestle elements to support them at predetermined positions above a supporting surface.
Claim 2
Dependent Claim
155 words
An adjustably positionable trestle to support flexible pipe comprising, in combination: a plurality of trestle elements each having a medial body portion, with means for releasably attaching supporting legs and means of maintaining a pipe thereon, and with flanges oppositely extending, in the axial direction of a pipe to be supported, each flange having an arcuate outer periphery and means of releAsably fastening to an opposite cooperating flange of an adjacent element; means of releasably fastening the opposed flange of one adjacent trestle element to that of another wherein the oppositely extending fastening flanges are offset so that when in communication the upper surface of the trestle elements is substantially coplanar to continuously support a pipelike element over both the body part and the flange part of the trestle; and a plurality of adjustably extensible legs adapted to be releasably carried by the trestle elements to support them at predetermined positions above a supporting surface.
Claim 3
Dependent Claim
71 words
The invention of claim 1 wherein at least one of the flanges in its forward surface is configured as a partial section of a truncated cone to allow adjustment between trestle elements and the fastening means between trestle elements comprise nut-bolt combinations extending through holes in the communicating flanges, at least one of which holes is somewhat larger than the bolt to allow angular positioning of one trestle member relative another.
Claim 4
Dependent Claim
74 words
The invention of claim 1 wherein the supporting legs are carried in leg fastening slots in the opposed lower lateral portions of the trestle body, and further characterized by: the supporting legs comprising two elements pivotably joined in scissorlike fashion with the fastening slot providing communication between trestle body element and legs configured as a dovetail joint so that when positioned, vertical loads on the legs aid the fastening of the leg to body.
Claim 5
Dependent Claim
125 words
In a trestle structure to support a flexible pipelike member, the combination comprising a trestle element having a medial body with means for supporting a pipe against displacement and oppositely extending flanges, each offset and adapted to releasably and movably communicate with an adjacent element to present a coplanar upper surface to support the lowermost element of the pipelike structure, each of such flanges having means for adjustable attachment to a cooperating opposed flange of an adjacent trestle element, the said trestle structure supported at a spaced distance above a horizontal surface by at least one leg structure comprising pivotably joined vertically adjustable legs communicating with a leg slot in a trestle element by a dovetail-type joint to resist displacement upon application of vertical forces.
Claim 6
Dependent Claim
125 words
In a trestle structure to support a flexible pipelike member, the combination comprising a trestle element having a medial body with means for supporting a pipe against displacement and oppositely extending flanges, each offset and adapted to releasably and movably communicate with an adjacent element to present a coplanar upper surface to support the lowermost element of the pipelike structure, each of such flanges having means for adjustable attachment to a cooperating opposed flange of an adjacent trestle element, the said trestle structure supported at a spaced distance above a horizontal surface by at least one leg structure comprising pivotably joined vertically adjustable legs communicating with a leg slot in a trestle element by a dovetail-type joint to resist displacement upon application of vertical forces.
