Abstract
Abstract The invention disclosed relates to a device for stacking printed circuit boards one on top of another. More particularly, the device includes a section for mounting the device in a hole in the board, an upper section extending above the board and having an upwardly open hole and a lower section extending below the board for insertion into an upwardly open hole in a device carried by the underlying board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A device for use with printed circuit boards so that the boards may be stacked one above another, said device comprising an elongated body of resilient material and including: a. an upper section adapted to extend above the board into which the device is mounted; b. an intermediate section including a cylindrical portion at the upper end, a frustum defining the lower end with the convergence being downwardly, and an outwardly flaring portion therebetween, c. an upwardly open hole extending downwardly into the elongated body; and d. a cylindrical lower section having a number of break-away segments in tandem, said lower section being adapted to be inserted into the upwardly open hole in a like device mounted on an underlying board.
Claim 2
Independent Claim
121 words
A device for use with printed circuit boards so that the boards may be stacked one above another, said device comprising an elongated body of resilient material and including: a. an upper section adapted to extend above the board into which the device is mounted; b. an intermediate section including a cylindrical portion at the upper end, a frustum defining the lower end with the convergence being downwardly, and an outwardly flaring portion therebetween, c. an upwardly open hole extending downwardly into the elongated body; and d. a cylindrical lower section having a number of break-away segments in tandem, said lower section being adapted to be inserted into the upwardly open hole in a like device mounted on an underlying board.
Claim 3
Dependent Claim
22 words
The device of claim 1 wherein the hole extends downwardly into the frustum so that the frustum may be resiliently, circumferentially reduced.
Claim 4
Dependent Claim
25 words
The device of claim 2 wherein the slope of the outwardly flaring portion is substantially less steep than the degree of convergence of the frustum.
Claim 5
Dependent Claim
39 words
The device of claim 3 wherein a downwardly facing shoulder adjacent the cylindrical portion is provided by the upper section, said shoulder being adapted to abut the upper surface of the board in which the device may be mounted.
