## Abstract

The invention relates to a swivel bearing for a pressing mechanism of a closing device. In order to create a swivel bearing that is easy to mount and inexpensive to produce, the pivotable unit is connected to the base plate by a journal located on the pivotable unit.

## Claims

### Claim 1

A closing device pressing mechanism including a swivel bearing and a lever arm, said closing device pressing mechanism adapted to prevent and allow movement of a closing device, the swivel bearing comprising:
a base plate fixed to the closing device, the base plate has a first journal shaped as a pin or a bolt;
a first guide sleeve fixed to the first journal;
a pivotable unit configured to receive the lever arm, the pivotable unit is pivotable with respect to the base plate; and
a second journal arranged on the pivotable unit, the second journal being shaped as a sleeve in order to receive the first journal of the base plate provided with the first guide sleeve, the second journal is in contact with the first guide sleeve.

### Claim 2 (depends on 1)

The closing device pressing mechanism according to claim 1, wherein a second guide sleeve is directly fixed to the first journal.

### Claim 3 (depends on 1)

The closing device pressing mechanism according to claim 1, wherein the pivotable unit is constructed as a housing.

### Claim 4 (depends on 1)

The closing device pressing mechanism according to claim 1, wherein the lever arm is fixed to the pivotable unit at a position offset from each of the first journal, the second journal, and the first guide sleeve.

### Claim 5 (depends on 4)

The closing device pressing mechanism according to claim 4, wherein the lever arm includes a force arm and a load arm on opposite sides of the swivel bearing, wherein the load arm is shorter than a force arm of the lever arm.

### Claim 6 (depends on 5)

The closing device pressing mechanism according to claim 5, wherein the load arm is bent as compared to the force arm.

### Claim 7 (depends on 6)

The closing device pressing mechanism according to claim 6, wherein the load arm includes an additional bend vertically to a plane of the closing device.

### Claim 8 (depends on 4)

The closing device pressing mechanism according to claim 4, wherein the pivotable unit includes a holding element for fixing the lever arm.

### Claim 9 (depends on 1)

The closing device pressing mechanism according to claim 1, further comprising a damper element.

### Claim 10 (depends on 9)

The closing device pressing mechanism according to claim 9, wherein the damper element includes a connection to the base plate.

### Claim 11 (depends on 1)

The closing device pressing mechanism according to claim 1, wherein the pivotable unit includes at least one limiting element.
