Abstract

A portable data processing device has a housing, a display, turnable holding arms arranged to hold the display above an upper side of the housing. Each of the holding arms has a holding arm-extension part provided with a blocking slider. The housing and the holding arm have locking recesses. The blocking slider has a first blocking portion which in one end position engaging in the locking recess of the holding arm and a second locking portion which in another end position engages in the locking recess of the housing. The blocking slider is spring biased in direction toward the locking opening of the holding arm and fixed in a locking position which is opposite to a spring force. The device also has a turning arm which locks the blocking slider in the locking position. The display is turnable and vertically movable between two different positions.

Claims

1. A portable data processing device, comprising a housing having an upper side;

a display;

turnable holding arms arranged to hold said display above said upper side of said housing, each of said holding arms having a holding arm-extension part provided with a blocking slider, said housing and said holding arm having locking recesses, said blocking slider being movable between two end positions and having a first blocking portion which in one of said end positions engages in said locking recess of said holding arm and a second locking portion which in another of said end positions engages in said locking recess of said housing, said blocking slider being spring biased in direction toward said locking opening of said holding arm and fixed in a locking position which is opposite to a spring force; and

a turning arm which locks said blocking slider in said locking position.

2. A portable data processing device as defined in claim 1, wherein said turning arm is formed as a cam disc provided with an arresting projection, said blocking slider having a corresponding arresting projection behind which said arresting projection of said cam disc is arrestable.

3. A portable data processing device as defined in claim 2, wherein said holding arm-extension part has a lateral recess, said turning lever extending through said lateral recess of said holding arm-extension part.

4. A portable data processing device as defined in claim 1, wherein said blocking slider has a lower side provided with a hook projection, said housing having an upper side provided with a recess so that said hook projection extends through said recess of said housing and engages said blocking slider in an arrested condition.

5. A portable data processing device as defined in claim 1, wherein said holding arm-extension part has a transverse wall, said blocking slider having a rear side;

and further comprising a helical spring which spring biases said blocking slider and abuts against said transverse wall of said holding arm-extension part and said rear side of said blocking slider.

6. A portable data processing device as defined in claim 1;

and further comprising a guiding rod which is transversely displaceable on said housing and provided with recesses, said turning lever being formed as a cam disc having pins which in a turned-in condition of said holding arm extension part extends in said recesses.

7. A portable data processing device as defined in claim 6, wherein said pins of said cam discs are arranged concentrically relative to a turning axis of said cam disc and offset perpendicularly to an axial longitudinal direction of said guiding rod.

8. A portable data processing device as defined in claim 7, wherein said guiding rod has portions which are offset relative to one another in correspondence with said offset of said pins of said cam disc.

9. A portable data processing device as defined in claim 6;

and further comprising guides which guide said guiding rod transverse and parallel to a lower edge of said display.

10. A portable data processing device as defined in claim 6, wherein said guiding rod has arresting recesses;

and further comprising a springy arresting projection engageable in said arresting recesses so as to arrest said guiding rod in two end positions.
