Installation frame for accommodating a device in an installation opening

1. An installation frame for accommodating a device in a predefined installation opening, comprising:

wall sections which enclose a largely cuboid cavity which is open at least on a front for accommodating the device, front edges of at least a portion of the wall sections forming flange-like outwardly projecting edge sections for resting against a front edge of the installation opening; and

a latching arrangement which projects to an outside from at least a portion of the wall sections and engages with a back of the installation opening, the latching arrangement having at least approximately arc-shaped sections which extend into the cavity and which have an end section which projects to the outside through the wall sections for engaging with the installation opening from behind in such a way that the arc-shaped sections are flattened when a device is inserted into the cavity and are elongated in a direction of the back of the installation opening so that the installation opening is clamped between the front edge sections and the latching arrangement of the installation frame.

2. The installation frame as recited in claim 1 , wherein the latching arrangement includes elastic tongues supported in an area of a wall opening.

3. The installation frame as recited in claim 2 , wherein tabs, which rest against corresponding edges of the wall opening in the wall sections, are molded onto the elastic tongues for supporting the elastic tongues in the area of the wall opening.

4. The installation frame as recited in claim 2 , wherein the elastic tongues are supported on an elastic strip on their ends facing away from a free end.

5. The installation frame as recited in claim 4 , wherein the elastic strip is formed by cutting a bearing point out of a wall of the installation frame.

6. The installation frame as recited in claim 1 , wherein the installation frame is manufactured from a spring steel sheet.

7. The installation frame as recited in claim 1 , wherein the radius of the arc-shaped sections increases in size as the device is inserted into the cavity.

8. The installation frame as recited in claim 2 , wherein the elastic tongues are deformed into one of a crescent shape and an arc shape, and the elastic tongues are connected to a bearing point via a bending edge.

9. An installation frame for accommodating a device in a predefined installation opening, comprising:

wall sections which enclose a largely cuboid cavity which is open at least on a front for accommodating the device; and

at least two elastic tongues, with a first one of the elastic tongues engaged with two installation opening on a first wall section, and with a second one of the elastic tongues engaged with two installation openings on a wall section opposite of the first wall section,

wherein front edges of at least a portion of the wall sections form flange-like outwardly projecting edge sections for resting against a front edge of the installation openings,

wherein each of the at least two elastic tongues is arc-shaped and extends into the cavity, and

wherein the arc shaped sections, when a device is inserted into the cavity, are: (i) flattened and (ii) elongated in a direction through the installation openings away from the cavity.

10. The installation frame as recited in claim 9 , wherein the arc-shaped area is limited to a subarea of the elastic tongues.

11. The installation frame as recited in claim 9 , wherein at least one of the wall sections has at least one opening used to attach the installation frame to the device.

12. The installation frame as recited in claim 9 , wherein the elastic tongues are formed from spring steel.

13. The installation frame as recited in claim 9 , wherein the elastic tongues are deformed into one of a crescent shape and an arc shape, and the elastic tongues are connected to a bearing point via a bending edge.
