## Abstract

A leveling device has a housing, a support surface which is fixed with the housing, an adjusting device including at least one adjusting screw which is displaceable outwardly and has an adjusting thread which is engageable with a counter thread for adjusting the adjusting screw, the counter thread being formed as a partially side of a slider which is displaceable transversely to a longitudinal axis of the adjusting screw and disengageable from the adjusting thread.

## Claims

### Claim 1

A leveling device, comprising a housing; a support surface which is fixed with the housing; an adjusting device including at least one adjusting screw which is displaceable outwardly and has an adjusting thread which is engageable with a counter thread for adjusting said adjusting screw, said counter thread being formed as a partial thread of a slider which is displaceable transversely to a longitudinal axis of said adjusting screw and disengageable from said adjusting thread.

### Claim 2 (depends on 1)

A leveling device as defined in claim 1; and further comprising a pressure spring arranged so that said slider is supported displaceable against a tensioning force of said pressure spring.

### Claim 3 (depends on 2)

A leveling device as defined in claim 2, wherein said slider cooperates with an arresting pin which in an arresting position of said slider holds it in a release position, in which said adjusting screw and said counter screw are not in engagement with one another.

### Claim 4 (depends on 3)

A leveling device as defined in claim 3; and further comprising a return spring, said adjusting screw in said releasing position being forced by said return spring to an initial position which is rearwardly offset in said housing.

### Claim 5 (depends on 3)

A leveling device as defined in claim 3; and further comprising a push button, said arresting pin being displaceable against a spring force by said push button.

### Claim 6 (depends on 5)

A leveling device as defined in claim 5, wherein said slider has an arresting opening, said arresting pin engaging in said slider through said arresting opening.

### Claim 7 (depends on 2)

A leveling device as defined in claim 2; and further comprising support legs each arranged on said housing on facing away side surfaces, said support legs being outwardly turnable over said support surface and are in operative connection with each other.

### Claim 8 (depends on 7)

A leveling device as defined in claim 7; and further comprising toothed gears through which said support legs are in engagement with one another.

### Claim 9 (depends on 7)

A leveling device as defined in claim 7, wherein said support legs are plate-shaped and have outwardly curved support edges.
