Abstract
Abstract A biplanar posting device having a board with a rear edge and a front edge and lines passing from the rear edge toward the front edge diverging toward the front edge and intersecting the front edge at an angle of about 70 degrees with a plate fixed to the upper surface of the board having end planar portions held in contact with the board and central diverging portions in the form of two flat planes diverging from the upper surface of the board at about 4 degrees and intersecting the planes in contact with the board at a line that overlays the diverging lines. An orthotic properly placed on the device and packed with plastic beneath the heel portion will inherently be formed with a lower surface to correct a defect in the bones of a patient.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A biplane posting device comprising: a board having a flat upper surface, a front edge and a rear edge and indicia forming a straight line diverging from the rear edge and toward the front edge at a first angle; and a thin plate overlying said upper surface, said thin plate having a planar portion parallel to said surface and in contact with it and a planar portion diverging from said upper surface at a second angle and with the line formed by the intersection of said planar surfaces overlying said straight line.
Claim 2
Dependent Claim
92 words
A biplane posting device comprising: a board having a flat upper surface, a front edge and a rear edge and indicia forming a straight line diverging from the rear edge and toward the front edge at a first angle; and a thin plate overlying said upper surface, said thin plate having a planar portion parallel to said surface and in contact with it and a planar portion diverging from said upper surface at a second angle and with the line formed by the intersection of said planar surfaces overlying said straight line.
Claim 3
Dependent Claim
13 words
The device of claim 1 wherein said first angle is about 70 degrees.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said second angle is about 4 degrees.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein said second angle is about 2 degrees.
Claim 6
Dependent Claim
13 words
The device of claim 1 wherein said second angle is about 6 degrees.
Claim 7
Dependent Claim
19 words
The device of claim 1 wherein said thin plate is removably attached to the upper surface of said board.
Claim 8
Dependent Claim
36 words
The device of claim 1 wherein said flat upper surface is comprised of at least two pieces of coating material connected to said board and abutting each other to form said straight line at their abuttment.
Claim 9
Dependent Claim
54 words
The device of claim 1 wherein said surface has two straight lines at said first angle diverging from the rear edge toward the front edge, said thin plate has two planar portions diverging from said upper surface and the two diverging planar portions intersect in a line bisecting the angle between said diverging lines.
Claim 10
Dependent Claim
16 words
The device of claim 7 wherein said two pieces of coating material are of different colors.
