For servicing PS devices, the chassis is two-fold - to be accessible from the top and bottom for measurements etc. in the most convenient way possible.

There are various solutions for this, all of which are more or less complex or ^{do not fulfill the desired 1} purpose ».,. constantly meet. '

The subject matter of the present G-eacB is a particularly simple and expedient embodiment of the guide rail for a chassis fastened on a reinforcing frame, which ; Underside releases to fix. ^: J '■

In Pig. 1 the guide rail is shown alone, while Pig. 2 to Pig. 3 the chassis running in the guide rail in the rest position, in the pulled out and in the folded up state. 18 is indicated in the illustration,

- ■ * · ■ ".
Like from Pig. 1 can be seen, the guide rail X has a guide slot * 2 which ends at the end * in two quarter circles 3u «4 . In addition, the lower quarter-round cutout has a recess 5. There is also an incision 6 on the outer edge of the sole, which is lowered at the end .

Two of these guide rails between which the chassis frame β ■ is mounted, represent the entire bracket. They are screwed with the screws 7 on the bottom of the Peraeehgehäuses. ^:

The chassis frame, in turn, has a guide bar for each guide rail (only the right half is drawn), whose thickness fits easily into the guide slot 2 and whose length corresponds to the sum of the two quarter-circle radii 5 and 4 . At the opposite end of the frame there is a screw 10 which fits into the slot 6 of the guide rail.

Afcf dexe Cli & ssisr & hffien bafindet eisii in the allgoaeiaien ciss device Mostly executed in cracked circuit - in the "'eis" that the electrical switching parts are on the top, while the circuit is on the bottom.

In the abnormal state, the one in Pig. 2 is the Chassis frame between the two guide rails in -horizontal position that on the one hand the guide web 9 of the Frame at the end of Ber guide rail 7 abuts, while the Sohraube 10 sits in the recess of the slot 6 and there feet = pulled that chassis locked in place.

If you want to pull the chassis out of the case, the Screws 10 loosened on the right and left, the chassis slightly raised so that the screws are pushed upwards a little and the frame is pulled out until the guide bar 7 strikes the other end of the rail.

Like Pig. 3 shows the chassis is through guide slot 2 and Guide bar 9 fixed in a horizontal position so that the components on the upper part of the device can now be easily approached * can come.

If you want to have access to the underside of the device, then it's after Fig. 4 only necessary to pivot the frame around the corners 11 and 12 acting as a pivot point upwards, which can be done without more is possible, as the guide bar of the frame fits exactly into the quarter circles. Haoh a pivot of 90 ° reached the end position by the stop of the guide webs at the boundaries of the quarter circles. By its own weight the chassis frame slips into the slot 5 whereby it is finally locked in this position. The bottom of the chassis is now more accessible.

To bring the device back into its horizontal position, the frame is lifted slightly so that the guide bar is pulled out of the slot 5 and then _{pivoted 90 downwards about its pivot point t} 11 and 12. '

The chassis in turn reaches its normal position by simply pushing it back and hooking the screws 6 in place will..

Instead of the screws 6, pins 13 be used, which sit firmly on the frame and when 'pushed in dee Frame push away a spring 15 provided with a hole 14 until they engage in the spring in the end position. The feathers must when pulling out the chassis until they release the pins. * In this case the slot needs 16 have no depression.

Apart from sheet metal, guide rails can also be made of plastic manufactured a, which has the advantage that the chase ice frame. is isolated from the housing.

Among other things, to remove the chassis completely from the guide rails and thus also from the device, it is initially horizontal to the rear pulled and then turned until the guide strateg the slot in the guide rail. The slot has the same * depth as the guide web, so that the chassis is in this position can be pulled out of the guide rails. · - ■
