Abstract
Abstract A pin which has one circumferential groove adjacent one end and has two axially spaced circumferential grooves adjacent its other end, is long enough to be inserted through a member of a knock down assembly, with its grooved ends extending beyond opposite faces of the member respectively, in position for either or both ends to be inserted through a slot in an opposed end of another member of the assembly and to receive in a groove the edge of a slot defining portion of an opposed other member of the assembly. At a predetermined position between its ends the pin is reduced in diameter for a predetermined distance and shaped so that two of the pins may be inserted through the said member in crossed relation and disposed in the same plane.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
A pin adapted to be inserted through a tubular support member of an assembly to connect the member with one or two other parts of the assembly said pin comprising a half round portion of reduced diameter disposed between two end portions which are round in cross section, one of said end portions being shorter than the other and defining one circumferential groove and the other of said end portions defining two axially spaced circumferential grooves, the pin being long enough so that when inserted through said member its grooved ends project beyond opposite faces of the member respectively and a retaining ring selectively seated in any of the said grooves, the portion of reduced diameter being so disposed between the end portions that two of the pins may be inserted through the support member at the same level and disposed in angularly related position in the same plane with the ends of each pin projecting from opposite sides of the support member.
Claim 2
Dependent Claim
163 words
A pin adapted to be inserted through a tubular support member of an assembly to connect the member with one or two other parts of the assembly said pin comprising a half round portion of reduced diameter disposed between two end portions which are round in cross section, one of said end portions being shorter than the other and defining one circumferential groove and the other of said end portions defining two axially spaced circumferential grooves, the pin being long enough so that when inserted through said member its grooved ends project beyond opposite faces of the member respectively and a retaining ring selectively seated in any of the said grooves, the portion of reduced diameter being so disposed between the end portions that two of the pins may be inserted through the support member at the same level and disposed in angularly related position in the same plane with the ends of each pin projecting from opposite sides of the support member.
Claim 3
Dependent Claim
68 words
The interconnecting pin claimed in claim 1 in which the portion of reduced diameter and the inner of the two grooves defined by the longer end portion of the pin are so disposed that the distance between the inner of said grooves and the outer end of the longer end portion of the pin is substantially equal to the length of the shorter end portion of the pin.
