Process and apparatus for retaining a circuit board in a mounted position in a computer housing

Claim 2

A retainer for retaining a circuit board in a mounted position in a housing of an electronic device; said retainer comprising: a body having a length and also having first and second end portions; a securing means for securing said first end portion to the circuit board; and said second end portion including an adjusting means for adjusting said length of said body to attain a working length so that when said first end portion is secured to the circuit board and the circuit board is mounted in the housing, said second end is positioned to engage the housing and retains the circuit board in the mounted position.

Claim 3

The retainer as claimed in claim 1 in which said adjusting means comprises at least one frangible portion which can be removed to enable said body to attain said working length.

Claim 4

The retainer as claimed in claim 2 in which said securing means comprises at least two resilient fingers which are generally biased towards each other and are capable of accommodating circuit boards of varying thicknesses.

Claim 5

The retainer as claimed in claim 3 in which the retainer includes a notice means for indicating that the retainer may be removed after installation of the electronic device.

Claim 6

A retainer for retaining a circuit board in a mounted position in a housing of an electronic device during shipment of the electronic device, said circuit board and housing having a working length therebetween when the circuit board is in the mounted position in the electronic device, said retainer comprising: a body having a length and also having first and second end portions; at least two resilient fingers located on said first end portion; said two resilient fingers being generally biased towards each other and adaptable for accommodating circuit boards of varying thicknesses; and said second end portion having a plurality of frangible portions which can be removed, as necessary, in order to adjust said length of said body to attain the working length so that when said first end portion is secured to the circuit board and the circuit board is in the mounted position in the housing, said second end portion is positioned to engage the housing and retain the mounted circuit board in the mounted position.

Claim 7

A retainer for retaining a circuit board in a mounted position in a housing of an electronic device during shipment of the electronic device, said circuit board and housing having a working length therebetween when the circuit board is in the mounted position in the electronic device, said retainer comprising: a body having a length and also having first and second end portions; at least two resilient fingers located on said first end portion; said two resilient fingers being generally biased towards each other and adaptable for accommodating circuit boards of varying thicknesses; and said second end portion having a plurality of frangible portions which can be removed, as necessary, in order to adjust said length of said body to attain the working length so that when said first end portion is secured to the circuit board and the circuit board is in the mounted position in the housing, said second end portion is positioned to engage the housing and retain the mounted circuit board in the mounted position.

Claim 8

The retainer as claimed in claim 5 in which said plurality of frangible portions are delineated by at least one score line to demarcate each frangible portion so as to enable the length of said body to be varied when one or more of said plurality of frangible portions is removed therefrom.

Claim 9

The retainer as claimed in claim 6 in which the retainer is of a predetermined color so as to indicate that the retainer may be removed after installation of the electronic device.

Claim 10

In an electronic device having a housing and a circuit board mounted in a mounted position within the housing and with a working length being defined as the distance between the mounted circuit board and the housing of the electronic device; the method for retaining a mounted circuit board in the housing during shipment of the electronic device, comprising the steps of: (a) selecting a retainer including a body having a length and also having first and second end portions; said second end portion having at least one frangible portion; (b) securing said first end portion to the circuit board; (c) removing, as necessary, one or more frangible portions from said body to attain the working length; and (d) positioning said retainer between the circuit board in the mounted position and the housing to retain the circuit board in the mounted position in the housing.

Claim 11

In an electronic device having a housing and a circuit board mounted in a mounted position within the housing and with a working length being defined as the distance between the mounted circuit board and the housing of the electronic device; the method for retaining a mounted circuit board in the housing during shipment of the electronic device, comprising the steps of: (a) selecting a retainer including a body having a length and also having first and second end portions; said second end portion having at least one frangible portion; (b) securing said first end portion to the circuit board; (c) removing, as necessary, one or more frangible portions from said body to attain the working length; and (d) positioning said retainer between the circuit board in the mounted position and the housing to retain the circuit board in the mounted position in the housing.

Claim 12

The method as claimed in claim 8 in which said securing step includes the step of: (bl) using at least two resilient fingers on said body which are generally biased towards each other and which are capable of accommodating circuit boards of different thicknesses to grip the circuit board.

Claim 13

The method as claimed in claim 9, in which said removing step includes the step of: (cl) separating each frangible portion with at least one score line so as to enable the length of said body to be varied by removing one or more frangible portions therefrom.

Claim 14

The method as claimed in claim 10, in which the method further includes the step of: (e) marking the retainer with a predetermined color so as to indicate that the retainer may be removed from the electronic device.
