Abstract

Abstract A multi-purpose display module system for an electrical instrument (10) has a readily detachable display module (30) for remote use that can be quickly reattached. The display module is readily adjusted in tilt angle, whether attached or remoted. A front frame (14) with a recess (16) is mounted on the front of a main chassis for the instrument. Latches (20) are mounted on the main chassis and extend into the recess on opposing sides of the recess, the ends of the latches defining a rotation axis across the recess. A display module has clutch assemblies (44) frictionally, rotatably mounted on opposing sides to fixedly engage the ends of the latches when the display module is mounted within the recess. Release of one latch allows the display module to be removed and set up independently with a stand (48) integral with the clutch assemblies, the display module being electrically connected to the electrical instrument by an electrical cable (36) of suitable length. The integral stand provides a means for remotely setting up the display module at any desirable viewing angle when remoted. Thus the tilt of the display module may be adjusted while the display module either is mounted within the instrument or is remoted from the instrument.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 123 words
A multi-purpose display module system for an electrical instrument (10) having a main chassis (12) comprising: a front frame (14) fixedly attached to the front of the main chassis, the front frame having a recess (16) and opposing slots (18) at either end of a rotational axis across the recess; a display module (30) for detachably, rotatably mounting within the recess; a pair of latches (20) attached to the main chassis and extending through the opposing slots; a pair of clutch assemblies (44) frictionally, rotatably mounted on the display module so that when the display module is mounted within the recess the clutch assemblies are fixedly engaged by the latches; and means (36) for electrically connecting the display module to the electrical instrument.
Claim 2
Dependent Claim 123 words
A multi-purpose display module system for an electrical instrument (10) having a main chassis (12) comprising: a front frame (14) fixedly attached to the front of the main chassis, the front frame having a recess (16) and opposing slots (18) at either end of a rotational axis across the recess; a display module (30) for detachably, rotatably mounting within the recess; a pair of latches (20) attached to the main chassis and extending through the opposing slots; a pair of clutch assemblies (44) frictionally, rotatably mounted on the display module so that when the display module is mounted within the recess the clutch assemblies are fixedly engaged by the latches; and means (36) for electrically connecting the display module to the electrical instrument.
Claim 3
Dependent Claim 83 words
A multi-purpose display module system as recited in claim wherein the display module comprises: a front panel section (38) having opposing ears (42) with central holes therethrough, each ear having a bearing surface around the central hole with the clutch assemblies mounted on the ears via the central holes; a back panel section (40) that engages the front panel section with a tongue and groove configuration to provide an EMI shield; and means for securely joining the front and back panel sections together.
Claim 4
Dependent Claim 74 words
A multi-purpose display module system as recited in claim 1 wherein the latch comprises: an elongate body having a mounting end (21) and a free end, the free end having an interior depression (28) and a ramp (22) and funnel (24) configuration to guide one of the clutch assemblies to engage the interior depression when mounting the display module within the recess; and means for fixedly attaching the mounting end to the main chassis.
Claim 5
Dependent Claim 111 words
A multi-purpose display module system as recited in claim 1 wherein each clutch assembly comprises: an interior casing (52); an exterior casing (54) that extends into the display module to engage the interior casing, the exterior casing having an exterior hub (46) that fixedly engages one of the latches when the display module is mounted in the recess; a spring (56) between the interior casing and an interior bearing surface of the display module so that when the interior and exterior casings are joined together frictional resistance to rotation is exerted between the clutch assembly and the display module; and means (78) for fixedly joining the interior and exterior casings together.
