Television receiver with a chassis held by means of chassis brackets or mounting brackets

The invention relates to a television receiver with means Chassis mounting or mounting brackets mounted chassis.

It is known to facilitate the service chassis as a folding chassis (see e.g. U.S. Patents 2,522,467, 2,566,064, 2,876,389). Also a vertical swivel Axis belongs to the state of the art (e.g. US-PS 2,350,889 or FR-PS 1,146,450).

It is also known to be pivotable or foldable Chassis in certain vertical, horizontal or intermediate positions to be locked by means of a grid (cf. e.g. the German utility model 1 856 157 or 7 115 59 3 of Applicant).

Furthermore, it is known to make the rear wall of television receivers pluggable or foldable by means of a plug connection (See e.g. the German utility models 7 029 338 and 1 987 156 of the Airneider).

In addition, television receiver housings are known in which the rear wall is used in whole or in part to hold the chassis. For example, in German Utility model 6 810 3 48 specified a holder for a vertical chassis in a television receiver housing, in which the chassis at the top and bottom, by means of Guides mounted so that they can be displaced perpendicular to the plane of the rear wall

and is held in the pushed-in state by the attached rear wall.

The invention is based on the object .for a chassis, on the one hand, a (provisional) bracket sufficient for the production cycle and service, on the other hand also to achieve a final attachment and support.

This object is achieved according to the invention in that the chassis is only hung or loosely fastened in the chassis holder or mounting bracket ι , while the actual or final fastening or holder is provided by means of the rear wall that is attached and largely encompasses the chassis.

According to one embodiment of the invention, the rear wall is provided in several, in particular three, in the housing cover Guide and fastening grooves inserted in such a way that the device and the chassis or the chassis frame of can be closed at the rear (by pivoting the rear wall).

According to another embodiment of the invention, on the inner sides of the rear wall are above and below and on the sides Cast in guiding and holding (fixing) and limiting ribs for the chassis reinforcement.

A preferred embodiment consists in that there are two upper and lower ribs, fixing and holding ribs, and two upper ribs and lower limiting ribs, one the chassis against tilting forward-holding rib and on each side two side borders and two different shapes at the same time Ribs holding the chassis on the right and left as well as one on each side of the chassis angles on the side and the chassis afterwards are cast on holding rib.

Further exemplary embodiments are specified in the subclaims.

The invention has the particular advantage that the chassis can be assembled easily and cost-effectively without screws can and is particularly cheap for the service. The chassis angles are only used for the production cycle and requires customer service while the chassis is secured by the backplane. The chassis is in the chassis bracket only temporarily attached for the production run and service and the final fastening and mounting takes place by putting on the back wall. In addition, the housing can be made relatively narrow.

An embodiment of the invention is shown in the drawing and described in more detail below. Show it

Figure 1 shows an embodiment according to the invention, partially in section, in side view,

Figure 2 is a view of the inner part of the rear wall.

The housing side wall 1 of the television receiver is at the top of the housing cover 2 and at the bottom of the housing base 3 Housing foot 4 limited. The chassis frame 5 is shown in its vertical position, which it finally secured State. The circuit board 6 is fastened on the chassis frame 5. The openings 7 in the chassis frame 5 are due to the tool and were created by pushing out the tabs 8.

The chassis frame together with the chassis is each with a chassis tab 9 in a receiving opening 10 in a chassis bracket 11 hooked. The chassis bracket 11 are means Fastening screws 12 attached to housing base 3. the

Receiving opening 10 has different edge profiles and bevels 13 on which the chassis tab 9 depending on the desired chassis position. Drawn in eggs Position, the chassis has a vertical position, so that the chassis flap 9 extends vertically and on the

corresponding bevel 13 rests and is locked. The chassis is tilted accordingly for other positions. A protruding from the chassis frame 5 T-shaped tab 14 is in the vertical chassis position in a recess 15 of the Chassis bracket engages and prevents the chassis

tilts backwards during the assembly process or during service.

The suspension of the chassis described so far is only a provisional holder for the ready-to-run device or for the service. The final fastening is done by the specially trained, in the following next

Back wall 16 with pot 17 described here.

is, or the rear wall with the chassis protruding into it is completely assembled.

For this purpose, the rear wall 16 is initially tilted (dash-dotted lines) into several (e.g. three) in the housing cover 2 provided guide grooves 18 are used. At the

Tilting the rear wall 16 latches on the one hand behind the chassis frame 5 and on the other hand fixes it by means of a number of holding, fixing and delimiting ribs, their design will be described below.

To the rear wall 16 made of plastic are at the top

ren, inner side two upper fixing ribs 19 cast,

which fix the chassis or the chassis frame 5 upwards with their edge 19a and which two lower fixing ribs below 20 correspond, which fix the chassis or the chassis frame downwards and limit the chassis upwards or downwards. Two more, upper ribs 21 are also on the upper inner side of the rear wall 16 cast .. They are shorter than the upper fixing ribs 19, jump shoulder-shaped in front and abut with their edges 21a from behind against the. Chassis frame 5 and fix the chassis in this way to the rear.

In a corresponding manner, two further lower ribs are cast on the lower inner side of the rear wall 16, which with their edges 22a on the lower side butt against the chassis frame 5 from behind and fix it to the rear.

Approximately in the middle of the inner upper side of the rear wall 16 is provided with a snap, preferably hook-shaped formed rib 2 3, which after pivoting the housing cover the chassis frame 5 from above and holds forward so that tilting of the chassis is no longer possible in this position. Thus the chassis frame, at the top firmly between the ribs 23 and 21 from the front and rear and held by the rib 19 from above.

In the upper quarter and in the middle of the inner left and right side wall 1 of the rear wall 16 are each a lateral Cast on rib 24 and 25, which are different in shape and which represent the lateral boundary of the chassis or the chassis holding frame and this to the right and keep left. Here, the upper narrow parts of the side ribs 24 form apart from the lateral guidance of the Chassis or chassis frame 5 at the same time reinforcing bars » ge for the rear wall 16 or the housing side wall 1.

They jump forward in the lower area and also have lateral projections 26 on the lower part, which may be can also be dimensioned so that they contribute to the support of the chassis. The one roughly in the middle of the inner one Side ribs 25 cast onto the side walls 1 of the rear housing wall 16 differ from the side ribs 24 in such a way that they have no lateral projections and in the upper half only a narrow strip of relative form low height.

In the lower quarter of the inner side case sidewalls 1 of the rear wall 16 are each a retaining rib 27 for the chassis bracket 11 cast. They form the side bracket the chassis bracket 11, but also hold the chassis bzs. the chassis frame 5 and fix it also against jumping out upwards by means of tabs that are exposed from the chassis frame. Through functional In the design of the tabs and the chassis bracket, the retaining ribs can have the same shape as the side ribs 24 received.

. If the chassis is to be folded out for service reasons, so only the rear wall 16 needs to be pivoted in the opposite direction as when it was inserted, i.e. with the lower one Edge pivoted away from the housing and then pulled out of the guide grooves 18 of the housing cover 2.

The chassis frame 5 or the chassis then only hangs in the chassis bracket 11 and can easily be tilted into one of the desired positions.
