be medium secured.

In the following, the invention will be described in more detail using an example
explained. I.

It shows

Pig. 1 shows a partial section through a door leaf with a

built-in profile cylinder lock secured according to the invention ,

Pig. 2 «a front view from Fig» 1 and
Pig. 3 a cut through a security rosette
of the invention with a securing means for fastening that is particularly easy to assemble
the security rosette on the profile cylinder lock.

In a door leaf 1 is a profile cylinder lock 2 for a

I mortise lock 3 used. The profile cylinder lock 2 | carries a security rosette 4, which is sunk into a recess 5 1 in the door leaf 1 and secured with the aid of a pin 6

is. I.

i A threaded hole 7 in the profile cylinder lock 2 is used in particular known way of fastening the profile cylinder ^{lock 2 s} in the mortise lock 3. Long shields 8 and 9 disguise the i

^^ _ Lock on the outside and are fastened with screws 10.

\ j * m * The opening 11 in the long shield 8 on the outside is included
largely adapted to the Porm of the security rosette 4.

The gap between the outer wall of the mortise lock 3 and f, which depends in its width on the thickness of the door leaf 1 the rear face of the safety rust 4 becomes | filled in by a plate 12 (? ign. 1 and 2). j

In the embodiment according to FIG. 3 there is a security rosette 13

used, with the help of a leaf spring U on the profile cylinder lock 2 is attached. This leaf spring H iet from the rosette opening 15 in the area of a groove 16 with one end 17 of which is inserted into a slot in the security rosette 13. With its other end 18, it can be in a Well 19 in the cylinder housing of the Px = Qfilzylindersohlossss 2 click into place.

The security grates 4 and 13 protrude only with their conical part from the door leaf 1 and through the long plate 8 to the outside. They completely enclose the profile cylinder lock 2. A tool attached here slides off. Daa engaging behind the security rosettes 4 _t 13 is not possible because they extend in the door leaf 1 to the mortise lock. 3
