Abstract
Abstract An electronic appliance with a pivotable display unit, a keyboard and a foot assembly having two lateral supports, with each lateral support including a base part and an upward extending side face. The lateral supports laterally receive the display unit in pivot bearings of the side faces at approximately half of the height of the display unit and receive a rear portion of the keyboard in support mounts arranged in the front area of the base parts. The electronic appliance can be set on a desk but can also be operated when the keyboard is removed from the foot assembly and the display unit with the foot assembly is set on the floor or secured to a wall. The electronic appliance is suited for used in programming machines for stored program controls.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
An electronic appliance with a display unit and a keyboard, comprising: two laterally arranged lateral supports, the display unit being pivotable on the two lateral supports, each of the two lateral supports including: a base part for providing a secure footing, each base part including a support mount in a front portion of the base part, and a side member extending upward from a rear portion of the base part, each side member including a pivot bearing, wherein the display unit is pivotally supported approximately about its center of gravity by the pivot bearings of the side members and a rear portion of the keyboard is received by the support mounts of the base parts.
Claim 2
Dependent Claim
115 words
An electronic appliance with a display unit and a keyboard, comprising: two laterally arranged lateral supports, the display unit being pivotable on the two lateral supports, each of the two lateral supports including: a base part for providing a secure footing, each base part including a support mount in a front portion of the base part, and a side member extending upward from a rear portion of the base part, each side member including a pivot bearing, wherein the display unit is pivotally supported approximately about its center of gravity by the pivot bearings of the side members and a rear portion of the keyboard is received by the support mounts of the base parts.
Claim 3
Dependent Claim
75 words
The electronic appliance of claim 1, wherein: the keyboard and display unit are configured substantially as flat modules with approximately the same outline; the support mounts and pivot bearings are arranged with respect to one another such that in a vertical position, the keyboard and the display unit are directly opposite one another and the electronic appliance is approximately rectangular; and a locking mechanism is provided for securing the electronic appliance in the vertical position.
Claim 4
Dependent Claim
17 words
The electronic appliance of claim 1, wherein the two lateral supports are interconnected by a rigid interconnection.
Claim 5
Dependent Claim
31 words
The electronic appliance of claim 3, wherein the rigid interconnection includes a support that is extendable in a rearward direction for increasing the stability of the electronic appliance against tipping over.
Claim 6
Dependent Claim
26 words
The electronic appliance of claim 3, wherein the support mounts of the base parts are configured as releasable pivot bearings so that the keyboard is removable.
Claim 7
Dependent Claim
69 words
The electronic appliance of claim 3, wherein a helical keyboard cable for electrical interconnection of the keyboard and the display unit is guided via a bearing through a first of the lateral supports, through a conduit with a U-shaped cross section extending in the rigid interconnection, to the second lateral support and via the pivot bearing of the side member of the second lateral support into the display unit.
Claim 8
Dependent Claim
23 words
The electronic appliance of claim 1, wherein at least one of the two pivot bearings of the side members includes a friction brake.
Claim 9
Dependent Claim
