Fixing of a chassis in the housing of a telephone subscriber station

ι The present invention includes a telephone part

j subscriber station with a lower housing part on which all

essential components of the station supporting chassis as well as an upper housing part are pivotably mounted.

; It is already known in telephone subscriber stations

one of the essential operating elements of the station such as keyboard, name buttons, loudspeakers, displays such as a padlock receiving intermediate carrier to be pivoted in the station housing in order to better reach the individual parts of the intermediate carrier during maintenance or renovation work.

; With the present subscriber station that is

* Upper part of the housing next to the chassis can be pivoted on the lower part of the housing stored. The problem with a station designed in this way is the chassis and the upper housing part to align to each other so that in the assembled

(State of the station the parts mentioned in vertical and

horizontal position to each other are set.

A fixation of the chassis within the station housing in the vertical and horizontal planes can thereby be achieved be that a nose is arranged on the upper housing part, which in the assembled state of the subscriber station presses on a resilient tab on the chassis, and that the chassis has a control panel that protrudes through a cutout in the upper part of the housing,

the chassis on the lower housing part in the horizontal Level is slidably mounted.

The nose on the upper part of the housing, which is wedge-shaped at its free end, acts as a fixture for the chassis in the vertical plane on the resilient tabs on the chassis, with manufacturing tolerances in this direction be compensated for by the yielding flap. To compensate for manufacturing tolerances in the horizontal The chassis is mounted displaceably in this plane. When assembling the subscriber station the chassis is first attached and swiveled towards the lower part of the housing. Then the ■: Upper part of the housing hung on the lower part of the housing and also pivoted in the direction of the lower part of the housing. Due to the mounting of the chassis, which allows displacement in the horizontal direction, this can take place for as long be moved until the control panel on the chassis is in the correct position within the cutout on the upper part of the housing is.

The invention is to be explained below using an exemplary embodiment.

The figure shows a sectional side view of the upper and lower housing part of a telephone user station mounted chassis.

the elongated holes 3 engage and thus pivoting of the chassis to carry out maintenance or repair work enable. On the front side facing the user, the upper housing part is on the lower housing part 1 7 pivoted. The cutout 8 in the upper part 7 of the housing takes the part containing the keypad, for example and control panel 9 indicated by dashed lines.

The subscriber station is assembled in such a way that first the chassis 5 on the lower housing part is suspended and pivoted in the direction of arrow A to the lower housing part 1. The upper part of the housing is on top 7 hung on the lower part of the housing 1 and in the direction of arrow B pivoted to the lower housing part 1. The control panel 9 arranged on the chassis extends through the cutout 8 in the Upper housing part 7 and protrudes slightly beyond it. Due to the mounting of the chassis in elongated holes, this can Move in the horizontal direction until the control panel 9 is exactly within the cutout. As a result, the chassis 5 is aligned with the upper housing part 7 in the horizontal plane.

To fix the chassis in the vertical plane Achieve, a wedge-shaped nose 10 is arranged at its free end on the upper housing part 7, the- in the assembled State of parts 1, 5 and 7 presses on a resilient tab 11 of the chassis 5. The final Connection of the upper housing part 7 with the lower housing part

1 can e.g. by screwing or locking these two Parts are made.
