Abstract

A locking device for a door or flap having a cylinder lock that has a cylinder bush and a cylinder core rotatably supported in the cylinder bush. A bearing bracket is fastenable to the door or flap and has a receptacle for the cylinder lock. A screw is also provided that establishes a mechanical connection of the cylinder bush to a trim element for the door or flap. The screw interacts with a threaded hole of a bow element in order to move the bow element. The cylinder bush has a radial recess, which forms a pressure tip at the end of the screw facing the cylinder bush, which pressure tip, while inserted in the radial recess, interacts with the pressure surface in order to axially and radially support the screw.

First claim

What is claimed is:

1. A locking device for a door or flap of a vehicle, the locking device comprising:
a cylinder lock that has a cylinder bushing and has a cylinder core that is rotatably supported in the cylinder bushing;
a bearing bracket fastenable to the door or flap and has a receptacle for the cylinder lock;
a screw that establishes a mechanical connection of the cylinder bushing to a trim element, wherein the trim element is an inner door panel; and
a bracket element that radially surrounds the cylinder bushing at least in part and is movably supported on the bearing bracket and has at least one engagement for engaging a recess of the cylinder bushing,
wherein the screw interacts with a threaded bore of the bracket element for the displacement thereof,
wherein the cylinder bushing has a radial indentation that forms a pressure surface,
wherein the screw has a pressure tip at an end facing the cylinder bushing that, when introduced into the radial indentation, interacts with the pressure surface to axially and radially support the screw,
wherein the pressure surface of the radial indentation is conical in design,
wherein the pressure tip of the screw is complementary to the pressure surface,
wherein the trim element has an opening through which the screw is passed, and
wherein the screw has a screw head whose diameter is larger than a diameter of the opening of the trim element, such that the screw head engages with the trim element.

2. The locking device according to claim 1 , wherein the bracket element is at least substantially annular in design and completely surrounds the cylinder bushing radially.

3. The locking device according to claim 1 , wherein the bracket element has a cross-rib as the engagement on the side opposite the threaded bore.

4. The locking device according to claim 1 , wherein the cylinder bushing has the recess on its side opposite the radial indentation.

5. The locking device according to claim 1 , wherein the recess is a receiving groove in the cylinder bushing.

6. The locking device according to claim 1 , wherein the bracket element has a first section surrounding the cylinder bushing and a second section having the threaded bore, and wherein the two sections are substantially perpendicular to one another.

7. The locking device according to claim 1 , wherein the bearing bracket has a slide guide for locating the bracket element to be displaceable primarily only radially with respect to the cylinder bushing.

8. The locking device according to claim 1 , wherein the screw head directly contacts an outer surface of the trim element to positively engage with the trim element when the pressure tip of the screw interacts with the pressure surface of the radial indentation of the cylinder bushing.

9. The locking device according to claim 1 , wherein the bracket element is annular such that it extends continuously around an outer surface of the cylinder bushing.

10. The locking device according to claim 1 , wherein, in a fully assembled state of the locking device, the trim element is discrete from and spaced apart from the bracket element and the bearing bracket, such that any contact between the trim element and the bracket element and between the trim element and the bearing bracket is an indirect contact.
