Concealed adjustable element for electronic circuit cards

Claim 2

In an electronic circuit card of the type comprising a generally planar board having a forward edge portion, a plurality of electronic components on said board, a plurality of terminals on said board adapted to be engaged with a plurality of corresponding terminals in an electrical panel and means on said board for electrically connecting said components in circuit with said terminals on said board, that improvement which comprises a panel secured to said board and supported thereby having upper and lower ends and extending transversely of the plane of the board adjacent said forward edge portion thereof, an adjustable circuit element electrically connected in circuit on said board and havinG an adjustable electrical parameter and an actuator for adjusting said adjustable element, said actuator being operatively connected to said adjustable element and disposed adjacent to said adjustable element proximate said forward edge within finger reach of one end of said panel and manually movable to continuously adjust said element, said actuator being located behind said panel so as to be concealed thereby and in a position to be manually accessible around one end of said panel from the forward side thereof.

Claim 3

The circuit card of claim 1 wherein said actuator extends transversely of the plane of said board a distance less than the transverse extent of said panel from the plane of said board.

Claim 4

The circuit card of claim 1 wherein said panel is substantially co-extensive in length with the forward edge of the board.

Claim 5

The circuit card of claim 1 wherein said actuat-or comprises a rotary member whose axis is substantially perpendicular to the plane of said board.

Claim 6

The circuit card of claim 4 wherein said rotary member is a wheel.

Claim 7

In an electronic circuit card of the type comprising a generally planar board having forward and rear borders and upper and lower borders, a plurality of electronic components on said board, a plurality of terminals on said board adjacent one of said borders and adapted to be engaged with a plurality of corresponding terminals in an electrical panel when said card is inserted into said panel and means on said board for electrically connecting said components in circuit with said terminals on said board, that improvement which comprises a front panel having upper and lower ends and extending transversely of said board and secured to the forward border thereof and supported by said board, an adjustable circuit element electrically connected in circuit on said board having an adjustable electrical parameter, an actuator for continuously adjusting said adjustable element whereby said electrical parameter is varied, said actuator being supported on said card and disposed adjacent to said adjustable element proximate said forward border within finger reach of one end of said panel, said front panel being positioned and dimensioned to conceal said actuator when said panel is viewed from the front of the card, said actuator being manually accessible from the front of said card.

Claim 8

In an electronic circuit card of the type comprising a generally planar board having forward and rear borders and upper and lower borders, a plurality of electronic components on said board, a plurality of terminals on said board adjacent one of said borders and adapted to be engaged with a plurality of corresponding terminals in an electrical panel when said card is inserted into said panel and means on said board for electrically connecting said components in circuit with said terminals on said board, that improvement which comprises a front panel having upper and lower ends and extending transversely of said board and secured to the forward border thereof and supported by said board, an adjustable circuit element electrically connected in circuit on said board having an adjustable electrical parameter, an actuator for continuously adjusting said adjustable element whereby said electrical parameter is varied, said actuator being supported on said card and disposed adjacent to said adjustable element proximate said forward border within finger reach of one end of said panel, said front panel being positioned and dimensioned to conceal said actuator when said panel is viewed from the front of the card, said actuator being manually accessible from the front of said card.

Claim 9

The circuit card of claim 6 wherein said panel extends transversely of the plane of said board a distance greater than the transverse extent of said actuator from said board.

Claim 10

The circuit card of claim 6 wherein said panel extends substantially the full length of the forward border and wherein said actuator is positioned adjacent the upper border of said board directly rearwardly of said panel.

Claim 11

The circuit card of claim 8 wherein said panel extends transversely of the plane of said board a distance greater than the transverse extent of said actuator from said board.
