## Abstract

A dummy trim includes a mounting plate to be fixed to a door, a sleeve holder securely mounted to the mounting plate and including a peripheral wall, a sleeve including a first end mounted in the peripheral wall of the sleeve holder, and a lever securely attached to a second end of the sleeve to move therewith. The first end of the sleeve includes a slot having an edge facing the lever. The peripheral wall of the sleeve holder includes an integral stop extending into the slot of the sleeve and abutting against the edge of the slot.

## Claims

### Claim 1

A dummy trim comprising:
a mounting plate adapted to be fixed to a door;
a sleeve holder securely mounted to the mounting plate and including a peripheral wall;
a sleeve including a first end mounted in the peripheral wall of the sleeve holder and a second end, the first end of the sleeve including a slot, the peripheral wall of the sleeve holder extending along a longitudinal direction of the sleeve; and
a lever securely attached to the second end of the sleeve to move therewith;
the slot of the sleeve having an edge facing the lever;
the peripheral wall of the sleeve holder including an integral stop extending into the slot of the sleeve and abutting against the edge of the slot, with the integral stop being punched from and remaining integral with the peripheral wall of the sleeve.

### Claim 2 (depends on 1)

The dummy trim as claimed in claim 1, wherein the integral stop is formed by means of pressing the peripheral wall of the sleeve holder in a position aligning with the slot.

### Claim 3 (depends on 2)

The dummy trim as claimed in claim 2, wherein the integral stop is inclined.

### Claim 4 (depends on 1)

The dummy trim as claimed in claim 1, wherein the integral stop is inclined.

### Claim 5

A dummy trim comprising:
a mounting plate adapted to be fixed to a door, with the mounting plate including an opening;
a sleeve holder securely mounted to the mounting plate and including a portion for abutting with the mounting plate and a peripheral wall extending from the portion and through the opening of the mounting plate;
a sleeve including a first end mounted in the peripheral wall of the sleeve holder and a second end, the first end of the sleeve including a slot, the peripheral wall of the sleeve holder extending along a longitudinal direction of the sleeve; and
a lever securely attached to the second end of the sleeve to move therewith the slot of the sleeve having an edge facing the lever;
the peripheral wall of the sleeve holder on the opposite side of the mounting plate than the portion including an integral stop extending into the slot of the sleeve and abutting against the edge of the slot, with the integral stop being punched from and remaining integral with the peripheral wall of the sleeve.

### Claim 6 (depends on 5)

The dummy trim as claimed in claim 5, wherein the integral stop is formed by means of pressing the peripheral wall of the sleeve holder in a position aligning with the slot.

### Claim 7 (depends on 6)

The dummy trim as claimed in claim 6, wherein the integral stop is inclined.

### Claim 8 (depends on 5)

The dummy trim as claimed in claim 5, wherein the integral stop is inclined.

### Claim 9

A method for mounting a dummy trim to a door, comprising:
fixing a mounting plate to a side of a door;
fixing a sleeve holder to the mounting plate, the sleeve holder including a peripheral wall extending along a direction perpendicular to an extending plan of the door;
mounting an end of a sleeve in the peripheral wall of the sleeve holder, the end of the sleeve including a slot, the slot having an edge;
punching the peripheral wall of the sleeve holder in a position that aligns with the slot, thereby forming an integral stop that extends into the slot of the sleeve and that abuts against an edge of the slot; and
fixing a lever to another end of the sleeve, with the integral stop stopping the sleeve when the lever is pulled to move the door.
