Description

The invention is directed to a device of the type specified in the preamble of claim 1. The device comprises a lock cylinder which is seated in a carrier and can be rotated by means of a defined key to actuate a lock associated therewith. In this case, the lock cylinder forms with the carrier a preassembled unit, which is fastened from the inside of the door as a whole. The protruding on the outside of the door parts of the lock cylinder are covered by a hood, which is fastened by means of a likewise to be handled from the inside of the door fasteners on the support.

Such a device is from the GB 2 415 743 A known. There is a first fastener here, which is to be handled from the inside of the door to screw the hood located on the outside of the door to the carrier. But then there are two more fastening means by which two superimposed components of a lock cylinder are connected to the carrier to form a structural unit. These other fasteners are directionally directed in their handling of the direction of attachment of the hood. For the multiple fasteners must be provided a multiple space for their arrangement and handling. This is space consuming and cumbersome.

From the DE 103 53 977 A1 Another device is known, where the hood is fastened by means of a screw to be actuated from the inside of the door to a support. An assembly between the carrier and the local lock cylinder does not exist.

From the DE 200 16 108 U1 a lock cylinder is inserted from the outside of the door through a hole in the door outer panel through into a bore of the local carrier, after which the protruding on the outside of the door part of the lock cylinder is covered by a hood. By means of a screw, the hood is anchored by a hole in the carrier in a threaded bore of the lock cylinder. Again, there is no assembly between the carrier and the lock cylinder, which could be mounted as a whole from the inside of the door. Rather, the three components are connected together only in the last phase of their assembly. This handling is also cumbersome.

The invention has for its object to develop a reliable device referred to in the preamble of claim 1 species that is inexpensive and is characterized by ease of use. This is inventively achieved by the measures specified in claim 1, which have the following special significance.

In the invention, the fastening means has a dual function. First of all, it ensures attachment of the hood to the wearer. Then, the same fastener has the task to hold the preassembled unit on the inside of the door. Although the assembly comes from the inside of the door and the hood is mounted from the outside of the door, they are fixed together by a common fastening means. It is thus only a single fastener to handle to place both the assembly and the hood in the right place of the door. As a fastener is a threaded screw, which has a shaft and a head. According to the invention, the screw shaft engages in aligned holes in the carrier, in the lock cylinder and in the hood.

It is recommended to provide the lock cylinder with a projecting flange on which the fastener can attack. In this case, the screw shaft engages in aligned holes of the carrier, the flange and the hood. Further measures and advantages of the invention will become apparent Subclaims and the description below. In the description, the invention is illustrated in two embodiments. Show it:

one too Fig. 1 analogous longitudinal section through an alternative embodiment of the device according to the invention, from which further details can be found.

Fig. 1 shows a basic structure of the device according to the invention shown on a door 10. In the door interior 13 is a carrier 30 which is pre-assembled with a lock cylinder 20. Carrier 30 and lock cylinder 20 form a structural unit 35 which is to be handled as a whole. In this case, the carrier 30 has an opening 38 in which the lock cylinder 20 is seated. The connecting means between the carrier 30 and the lock cylinder 20 are not shown in detail. This assembly 35 is mounted from the inside of the door 11 behind a door outer panel 15. In this case, the lock cylinder 20 has parts 21 which protrude on the outside of the door and / or are accessible from the outside of the door 12.

The lock cylinder 20 is in the case of installation with a in Fig. 1 only dash-dotted lines indicated lock 40 connected. The lock 40 has a closing element 41, which protrudes on the door narrow side 14. The closing element 41 has the task of keeping the door closed or to release the door 10 to open. The latter is usually done by a door handle, not shown in detail, which acts on the lock 40.

An important task of the lock cylinder 20 is to adjust the lock 40 between an operative position and an inoperative position. This is done by means of a key 40 associated with the key 19 of the door outside 12 inserted into the lock cylinder 20 of the assembled unit 35 and can be rotated. As a connecting means between the lock cylinder 20 and the lock 40 is here a so-called paddle 29, which is the rotation of a in Fig. 1 not shown in detail cylinder core by the key 19 on lock parts in the lock 40 transmits. By rotation of the inserted key 19 also takes place a rotation of the paddle 29, whereby the lock parts are adjusted between an effective and an ineffective position.

On the display side 17 of the door outer panel 15 is a hood 42.1, which is mountable from the outside of the door 12. The hood 42.1 includes an axial opening 43 to allow the key 19 access to the lock cylinder 20. The hood 42.1 is set in alignment with the lock cylinder 20 and covers the protruding on the outside of the door 12 lock cylinder parts 21, which come to lie in the hood inner 44.

There is provided a fixing means 31 for the hood 42.1, which is basically only from the inside of the door 11 to operate. This fastening means consists of a screw 31, which comprises a screw shaft 32 and a screw head 33. How the attachment of the hood 42.1 happens, is based on the second embodiment of Fig. 2 be explained. The hood 42.2 in Fig. 2 is opposite Fig. 1 formed modified, but agrees the assembly process of the respective hood 42.1, 42.2 in both cases.

According to Fig. 2 the lock cylinder 20 is provided with a lateral flange 23 which covers a portion of the support 30 of the assembly 35. Both the flange 23 and the carrier 30 are each provided with a hole 24 and 34, through which the screw shaft in the direction of the arrow 36 can be pushed. The screw shaft 32 passes through when plugging 36 at the same time the aforementioned opening 18 in the door outer panel 15 and engages in a threaded receptacle 55 of the hood 42.2 a. The illustrated by a rotary arrow 37 screwing the screw 31 is carried out on the screw head 33 and takes place, as already said, only from the door interior 11. The course of a screw axis of the screw shaft 32 in the case of installation is in Fig. 2 dash-dot illustrated. It can be seen that the screw axis 39 extends at an angle of inclination 46 to the axis 28 of the lock cylinder 20.

The threaded receptacle 45 consists of a blind hole in the hood 42.2. This blind hole is based on an inner end face 47 of a side wall 48 of the hood 42.2. The side wall 48 has a slope course whose direction is determined by the aforementioned screw axis 39. The screw head 33 is supported on a support surface 27.2, which in the hood 42.2 of Fig. 2 is located on the lock cylinder flange 23.

The attachment of the hood 42.1 of the first embodiment in Fig. 1 carried out in an analogous manner. A difference arises because the sequence of the lock cylinder flange 23 on the one hand and the carrier 30 is reversed in both cases. Thus, the screw head 33 is supported in Fig. 1 at a. Support surface 37.1 from which is arranged on the carrier 30.

Out Fig. 2 Further details of the lock cylinder 20 are shown, of course, in an analogous manner in the embodiment of Fig. 1 are provided. Of course, this includes a cylinder core 25 with tumblers arranged therein, which are sorted by the inserted key and, if successful, permit a rotational actuation of the cylinder core 25. The cylinder core 25 and its further cylinder sleeve are arranged in a cylinder housing 26, with which the lock cylinder 20 is preassembled in the carrier 30.

In both embodiments diametrically opposed to the point of engagement 49 of the threaded screws 31 described are also still clutch means 50.1 and 50.2 arranged on the hood 42.1 and 42.2. This coupling means 50.1, 50.2 provide for a further connection between the hood 42.1 or 42.2 and the associated structural unit 35. The coupling means 50.1, 50.2 themselves are formed differently from each other in both cases and will be described separately below. The joining of the two coupling means 50.1 and 50.2 is carried out by a multi-movement several Einrenkbewegung, the first Movement phase is a Einsteckphase, by arrows 60.1 and 60.2 in the Fig. 1 or 2 is clarified.

The coupling agent 50.1 of Fig. 1 comprise a first, movable coupling part 51.1 which is part of the hood 42.1 to be mounted. This first coupling part 51.1 is associated with a second, stationary Gegenkupplungsteii 52.1, which is part of the assembly 35. The first coupling part 51.1 is hook-shaped and has a shoulder 53.1 at its hook end. After completion of the Einrenkbewegung whose second phase of movement comprises a displacement of the hook-shaped coupling part 51.1 in a coupling receptacle 54.1, the shoulder 53.1 passes under a counter-shoulder 55.1, which is part of another radial flange 56 of the lock cylinder 20 here. The coupling receptacle 54.1 is embedded in the carrier 30. The coupling receptacle 54.1, the additional radial flange 56 and its counter-shoulder 55.1 are components of the aforementioned second counter-coupling part 52.1.

Although the Einrenkbewegung between the hood 42.1 and attached to the inside of the door assembly 35 takes place on the outside of the door 12, but thereby affects the door interior 13, that the hook-shaped first coupling part 51.1 through the opening 18 already described in the door outer panel 15 in the sense of Insertion arrow 60.1 is inserted. The hook of this coupling part 51.1 is oriented radially inwards towards the axis 28 of the lock cylinder 20. The last phase of the Einrenkbewegung then takes place inside the door in the coupling receptacle 54.1.

The coupling means 50.2 of the second embodiment of Fig. 2 are formed in an analogous manner, which is why the previous description of the first embodiment largely applies in the second embodiment as well. It is sufficient here only on the differences of Fig. 2 enter into.

Also located on the hood 42.2 first coupling part 51.2 has hook shape, but the hook has radially outward. The arrow 60.2 in Fig. 2 illustrates Einsteckphase the Einrenkbewegung requires a tilting position of Hood, so that the hook end with his shoulder 53.2 can reach into the inside of the door 11 located analog coupling receptacle 54.2. After completed Einrenkbewegung, enters the shoulder 53.2 behind a counter-shoulder 55.2. The second phase of the Einrenkbewegung includes a tilting back of the hood 42.2 on which also in this case on the outside of the door 12 located lock cylinder parts 21 causes. In the present case, the counter-shoulder 55.2 is formed by a portion of the rear side 16 of the door outer panel 15, which is located in the region of the coupling means 50.2.

In the second embodiment of Fig. 2 the hood 42.2 additionally has a radially inward-pointing axial shoulder 57, which engages behind a counter paragraph 58 in the lock cylinder 20 after completed Einrenkbewegung.

In both embodiments, the front end 59 of the lock cylinder 20 is provided with an armor plate 61, which consists of hardened steel. The armor plate 51 is intended to prevent burglary attempts by unauthorized persons. Therefore, the armor plate 61, as in particular from Fig. 2 shows a narrow passage gap 62 for the off Fig. 1 apparent key 19. How Fig. 2 shows, the armor plate 61 is rotatably mounted in the cylinder housing 26 and when not in use, a spring-loaded flap 63 closes the passage gap 62. In addition, the armor plate 61, as Fig. 2 particularly clearly shows the axial opening 43 in the hood 42.2 largely close.
