1 a to 1 d show a locking cylinder 1 according to the invention. The locking cylinder 1 can be designed as a profile cylinder or as a round cylinder with a bridge 2. The locking cylinder 1 in FIGS. 1 is composed of a bridge 2 and two housing parts 3 and one each arranged therein Lock cylinder assembly 4 together. The lock cylinder assembly 4 is referred to below as insert 4.

Only one side of the locking cylinder 1 is described below, since the bridge 2 and the arrangement of the housing parts 3 are symmetrical. The symmetry is illustrated in FIGS. 1 a and 1 c by the plane of symmetry 2se. The description of one side also applies to the other side if no differences are explicitly listed. This also applies to the labels in the figures. Each component is described below with a front and a rear area. The rear area always refers to the part of the component which is formed towards the plane of symmetry 2se of the bridge and the front area always relates to the part of the component which is formed from the side facing away from the plane of symmetry 2se of the bridge.

As shown in FIG. 1, the bridge 2 is composed of a web part 2s and two profile parts 2p, which are formed symmetrically to the plane of symmetry 2se on the web part 2s. The web part 2s and the profile parts 2p are formed in one piece. Each profile part 2p has a front area, that is to say an area facing away from the plane of symmetry 2se, which has a front receiving area 2av and a rear area which has a rear receiving area 2ah. The front receptacle area 2av - hereinafter referred to as the front receptacle 2av - interacts with the housing part 3. The rear receiving area 2ah - hereinafter referred to as rear receiving 2ah - is designed such that a cam 6 is rotatably arranged between the two profile parts 2p. The cam 6 has a lock bit 61, the lock bit 61 being able to actuate a lock (not shown in the figures) when the lock cylinder 1 is actuated. The housing 3 interacts with its rear receptacle 3ah with the bridge 2, ie with the front receptacle 2av in the profile part 2p of the bridge 2. Furthermore, the housing 3 has a passage 3d, which is referred to below as

Breakthrough 3d is called. An insert 4 is arranged in the opening 3d. The breakthrough 3d of the housing 3 is eccentric

Housing wall formed, i.e. the axis of the housing wall Ag and the axis of the opening Ad do not lie in one another. The insert 4 can hold a key (not shown in FIGS. 1) for actuating the locking cylinder 1, the cam 6 rotating to unlock or lock a lock (not shown) by the rotary movement of the key.

Figure 1 e shows an exploded view of the lock cylinder 1 from Figures 1 a to 1d. The insert 4 has one on its front side

Key channel 4ks for receiving a key (not shown in the figures) on and on its rear side a coupling 4k of the rotor of the insert 4, through which the rotary movement of the key is transmitted to the cam 6. The clutch 4k is referred to below as the clutch of the insert. The insert 4 is arranged in the opening 3d of the housing part 3 and is fixed in it in a rotationally and tensile manner by screws 3s or locking screws 3ss.

The opening 3d is formed in the housing part 3 such that the insert 4 can be inserted on the front side of the housing part 3. The opening 3d has a smaller one on the rear side of the housing part 3 Radius on. This protruding wall serves as a stop at 3w

Inserting the insert 4. Only the coupling 4k of the insert 4 passes through the rear part of the opening 3d (see also FIG. 7). The rear part of the housing further has the rear receptacle 3ah, which interacts with the front receptacle 2av of the bridge 2. The rear receptacle 3ah of the housing 3 and the front receptacle 2av of the bridge 2 in the profile part 2p are designed to be complementary to one another.

The bridge 2 has the front receptacle 2av and a passage 2d in the profile part 2p. Passage 2d is referred to below as breakthrough 2d. The coupling 4k of the insert 4 passes through the breakthrough 3d of the housing 3 and the breakthrough 2d of the bridge 2 (see also FIG. 7). The coupling 4k can be designed in such a way that the coupling 4k ends flush with the profile part 2p or that part of the coupling 4k extends through the opening 2d of the bridge 2 into the rear receptacle 2ah of the bridge 2. In both cases, the coupling 4k of the insert 4 interacts with a coupling 6k of the cam 6 in order to transmit the rotary movement of the key (not shown in the figures) to the cam 6. Furthermore, threaded holes 3g are formed in the housing 3 on the underside, into which screws or security screws 3s can be screwed for fastening the insert 4. Threaded holes 2g are formed in the bridge 2, which are penetrated by screws 3s in order to fix the housing 3 in the bridge.

FIGS. 2a to 2e show a further embodiment of the

Lock cylinder 1 according to the invention shown. In contrast to the lock cylinder 1 shown in FIGS. 1, the lock cylinder 1 points in FIG Figures 2 additional extension parts 5. The captions and

Descriptions from FIGS. 1 also apply to FIGS. 2, except for the extension parts 5 and the additional parts required thereby. In FIGS. 2, the extension part 5 to the left is shorter than the extension part 5 to the right. The extension parts 5 differ only in length, i.e. the passages 5d and receptacles 5av and 5ah are identical in the short and long extension parts 5

educated. Versions with two long or two short extension parts 5 or versions with several are also possible

Extension parts 5 in a row.

The extension part 5 has a rear receptacle 5ah which interacts with the front receptacle 2av of the profile part 2p. Furthermore, the extension part 5 has a front receptacle 5av which interacts with the rear receptacle 3ah of the housing 3. So that can

Extension part 5 can be arranged between the housing 3 and the bridge 2. As in FIGS. 1, the extension part 5 is fixed via lateral threaded holes, which are penetrated by screws 3s.

2e differs from FIG. 1e in that the extension parts 5 are arranged between the housing 3 and the bridge 2. Each

Extension part 5 has a passage 5d, which is referred to below as opening 5d. The breakthrough 5d can be a

Take up rotor extension 5r. The outside diameter of the

Rotor extension 5r corresponds to the outer diameter of the coupling 4k of the insert 4. The rotor extension 5r in the extension part 5 passes through the opening 2d of the bridge and does not transmit the rotary movement of the key shown in insert 4 on the cams 6. Next is in the

Rotor extension 5r a cylinder pin arranged as a key extension 5s, which the axial pushing movement of the key from a housing 3, e.g. transmits the left housing 3 to the right housing 3. Thus, when a key is inserted into insert 4 on the left, a key which is in insert 4 on the right becomes one piece

pushed out and can therefore no longer operate the lock cylinder 1. This ensures that the locking cylinder 1 can only be actuated from one side.

The individual components of the lock cylinder 1 of FIGS. 1 and 2 are described further below. These descriptions apply in addition to the previous description of the individual components. In Figures 3a to 3q, the one-piece bridge 2 consists of the

Web part 2s and the profile parts 2p shown. In addition, the symmetry plane 2se of the bridge 2 is shown here. As in Figures 3a to 3g

shown, the profile part 2p has a U-shaped receiving groove 2n. The front receptacle 2av of the profile part 2 is formed by the U-shaped receiving groove 2n. The receiving groove 2n forms the receiving surface 2f of the front receiving 2av of the profile part 2p through the bottom of the receiving groove 2n and the upper surface of the groove edge.

As shown in FIG. 3b, the axis Aa of the semicircular region of the receiving groove 2n of the front receiving 2av lies on the axis Ag

Outer wall of the profile part 2p. The outer wall of the profile part 2p corresponds to the outer wall of the housing part 3 and the extension part 5 (see Figures 1 and 2). As shown in Figures 3e to 3h, lie the axes of the semicircular receiving surface 2f of the groove bottom and the upper surface of the groove edge form one another and thus form the axis Aa of the holder 2av. The axis Ad of the breakthrough 2d of the bridge is, as shown in FIG. 3b, offset upwards from the two previously described axes.

The bridge 2 in FIGS. 1 to 3 has a threaded hole 2g in the web part 2s, which is used to fasten the locking cylinder 1 in a known manner in a door, not shown. It is a so-called

Forend fastening hole.

Figures 4 show the housing part 3 from Figures 1 and 2. Das

As already described above, housing part 3 has a rear receptacle 3ah. This is complementary to the front receptacle 2av of the profile part 2p and can thus engage in the receptacle 2av of the profile part 2p. The housing 3 has an inwardly offset U-shaped receiving groove 3n, which forms the receiving surface 3f of the housing 3 through the groove bottom and the parallel surface of the groove wall. The receiving surfaces 3f, formed by the groove bottom and the parallel surface of the groove wall, lie as in FIGS

4 can be seen, centered on the outer wall of the housing part 3.

Figure 4b additionally shows that the opening 3d of the housing 3 is eccentric to the outer wall of the housing 3. The axis Ad des

Breakthrough 3d of the housing part 3 is formed offset upwards to the axis Aa of the receptacle 2av. FIGS. 4e and 4h to 4o further show the rear stop 3w in the opening 3d, which has already been described with reference to FIG. 1e. The opening 3d has a smaller diameter on the rear side of the housing part 3, which is due to the Coupling 4k of the insert 4 is penetrated, but is designed for the insert 4 as a stop 3w. FIG. 4f and FIG. 4i show the threaded holes 3g for fastening the insert 4. FIG. 5 shows an insert 4 from FIGS. 1 and 2. The insert 4 is composed of an insert rotor 4r, which is rotatably mounted, an insert stator 4s and a sleeve 4h. The insert rotor is referred to below as rotor 4r and the insert stator as stator 4s. The rotor 4r is rotatably arranged in the stator 4s. The stator 4s is fixed in the sleeve 4h. The sleeve 4h forms a housing of the insert 4 which is fixed to the stator 4s.

The rotor 4r has a key channel 4sk and the clutch 4k at its rear end. Furthermore, the rotor 4r has bores 4b for receiving bolts 4g. The stator 4s also has bores 4b for receiving the bolts 4g and the counter bolts and the springs 4f. The spring 4f presses the counter bolts on the bolts 4g, which are thereby pressed onto the key, not shown in the figures. Bolts 4g of different lengths require different depth bores on the key so that the bolts 4g close exactly with the outer diameter of the rotor 4r when the correct key is inserted in the key channel 4sk. Then the rotor can be turned. If the key is not inserted or the wrong key is inserted, the bolts and counter bolts engage in the bores 4b of the rotor 4r and thus block the rotation of the rotor 4r. The rotor 4r with the stator 4s are arranged in the sleeve 4h. The front area of the rotor 4r has a larger diameter than the opening of the sleeve 4h and is the front extended end above the sleeve 4h forth. In the rear area of the sleeve 4h, the rotor 4r and the stator 4s are secured in the sleeve 4h by a snap ring 4sr.

6 shows long and short extension parts 5 from FIGS. 2. FIGS. 6a to 6I show long extension parts 5. FIGS. 6m to 6x show short extension parts 5 and differ from the long extension parts 5 of FIGS. 6a to 6I only in the smaller one axial

Extension. In the following only the figures 6a to 6I are described, whereby this description applies analogously to the short extension parts 5 of the figures 6m to 6x. The extension parts 5 differ only in length, i.e. the openings 5d and receptacles 5av and 5ah are formed identically in the short and long extension parts 5.

The extension part 5 has at its front area a front receptacle 5av which is connected to the rear receptacle 3ah of the housing 3 or the rear receptacle 5ah of a further extension part 5

cooperates. Furthermore, the extension part 5 has at its rear area a rear receptacle 5ah, which is connected to the front receptacle 2av of the profile part 2p or a front receptacle 5av

Extension part 5 cooperates. The front seats of all components are complementary to the rear seats of all components.

As shown in FIGS. 6, the extension part 5 has a U-shaped receiving groove 5nv in the front receiving 5av. This receptacle 5av is identical to the front receptacle 2av of the profile part 2. Ie the front receptacle 5av is formed from the U-shaped receptacle groove 5nv. The receiving groove 5nv forms the front receiving surface 5fv of the front receptacle through the bottom of the receiving groove 5nv and the upper surface of the groove edge 5av off. As shown in Figure 6, the axis Aa of the front receptacle 5av lies on the axis Ag of the outer wall of the extension part 5. Die

The outer wall of the extension part 5 also corresponds to the outer wall of the housing part 3. The axis Ad of the opening 5d is, as shown in FIG. 6, offset upwards from the two previously described axes.

The rear receptacle 5ah of the extension part 5 is identical to the rear receptacle 3ah of the housing part 3. I.e. the

Extension part 5 has an inwardly offset U-shaped receiving groove 5nh, which forms the receiving surface 5fh of the extension part 5 through the groove bottom and the parallel surface of the groove wall. The receiving surfaces 5fh, formed by the groove bottom and parallel surface of the groove wall, are, as shown in FIGS. 6, centered on the outer wall of the extension part 5. The axis Ad of the opening 5d is offset upwards from the axis Aa of the holder 5av.

Figures 7 show sectional views of the lock cylinder 1 from Figures 1 and 2. Figures 7b and 7d show the sectional views through the sectional planes B-B and C-C of Figures 7a and 7c. The cuts B-B and C-C run once through the receiving groove 2n of the bridge 2 and once through the receiving groove 3nh of the housing 3. FIGS. 7 show the

complementary design of the front receptacle 2av of the bridge 2 and the rear receptacle 3ah of the housing part 3 and that the front receptacle 2av of the bridge 2 and the rear receptacle 3ah of the housing part 3

intervene seamlessly. The screws with hexagon socket for holding the housing 3 in the bridge 2 are also shown in FIGS. The screws engage in the threaded holes 2g of the profile part 2 and further engage in blind holes in the housing 3 (see FIGS. 6, blind holes in the rear receptacle 5ah).

FIGS. 7g and 7h show sectional representations through the sectional plane E-E of FIG. 7f, the insert 4 not being shown in section here. FIGS. 7f to 7h show the screws 3s or security screws 3ss inserted into the housing 3 from below, which secure the insert 4 against being pulled out and turned. The clutch 4k of the insert 4 engages in the opening 2d of the profile part 2p and interacts with the clutch 6k of the cam 6.

FIGS. 7j and 7k show sectional representations through the sectional plane D-D of FIG. 7i, the insert 4 here not being shown in section. in the

In contrast to FIGS. 7f to 7h, in FIGS. 7i to 7k the extension parts 5 are additionally on the left and right side of the

Lock cylinder 1 arranged. So that the rotational movement of the insert 4 can be transmitted to the cam 6 via the clutch 4k, between the

Coupling 4k and the coupling 6k of the cam 6, a rotor extension 5r arranged in the opening 5d of the extension part 5. The rotor extension 5r passes through the opening 2d of the profile part 2p. The length of the

The rotor extension 5r corresponds to the length of the extension part 5.

Figures 8 to 12 show different configurations of the bridge 2 of Figures 1 to 3. The bridges 2 of Figures 8 to 12 differ from the bridges 2 of Figures 1 to 3 only in the different design of the opening 2b of the profile part 2p. In contrast to the opening 2b from FIGS. 1 to 3, in FIG. 8 the opening 2d is designed as a U-shaped opening 2b which cuts through the profile part 2p towards the top. Furthermore, the axis Ad of the semicircular part of the opening 2b corresponds to the axis Aa of the receptacle 2av and the axis Ag of the housing circumference or the outer circumference of the

Profile part 2p, i.e. In this embodiment, the opening 2b is additionally centered on the front receptacle 2av of the profile part 2p and

Outer periphery of the profile part 2p formed. In contrast to the opening 2b from FIGS. 1 to 3, the opening 2d in FIG. 9 is designed as a central circular opening 2b with a large diameter. The axis Ad of the round opening 2b corresponds to the axis Aa of the receptacle 2av and the axis Ag of the housing circumference or the outer circumference of the profile part 2p, i.e. the opening 2b is formed centrally to the front receptacle 2av of the profile part 2, i.e. In this embodiment, the opening 2b is additionally formed centrally to the front receptacle 2av of the profile part 2p and the outer circumference of the profile part 2p.

In contrast to the opening 2b from FIGS. 1 to 3, the opening 2d in FIG. 10 is designed as an elongated hole. Both the axis Ad of the upper and the axis Ad of the lower semicircle lie outside the axes Aa of the receptacle 2av and outside the axis Ag of the circumference of the housing or the circumference of the profile part. In contrast to the opening 2b from FIGS. 1 to 3, the opening 2d in FIG. 11 is designed as an elongated hole which is open at the top, i.e. The elongated opening 2d from FIGS. 10 is upward

postponed. The axis Ad of the lower semicircle of the opening 2d lies outside the axis Aa of the receptacle 2av and outside the axis Ag of the housing circumference or the profile part circumference.

In contrast to the openings 2b from FIGS. 1 to 3, the opening 2d in FIGS. 12 is octagonal.

All the designs described above have in common that the axis of the receptacles is identical to the axis of the outer circumference of the respective component. The semicircular area of the respective receptacles, which is formed by the contact surfaces, counts. This applies to both the profile part 2p and the extension part 5 and the

Housing part 3 and for both the front and the rear recordings.

In contrast to the components: bridge 2, housing part 3 and extension part 5 of FIGS. 1 and 2, the components: bridge 2, housing part 3 and extension part 5 of FIGS. 13 to 16 have receptacles which are formed eccentrically to the outer edge of the components. In the following exemplary embodiments in FIGS. 13 to 16, the axes Ag of the housing no longer overlap with the axes Aa of the receptacles.

FIGS. 13 show a bridge 2 with an eccentric receptacle 2av in the profile part 2 and different designs of the openings 2d. In contrast to the bridge 2 of FIGS. 1 to 3, the front receptacle 2av of the profile part 2p of FIGS. 13a to 13h has an eccentric axis Aa of the receptacle 2av with respect to the axis Ag of the housing. The axis Aa of the receptacle 2av overlaps in FIG. 13 with the axis Ad of the opening 2d. The design of the receiving groove 2n and the receiving surfaces 2f corresponds to the exemplary embodiments in FIGS. 1 to 3, these now having an axis Aa offset upwards.

FIGS. 13g to 131 show bridges 2 with an eccentric receptacle 2av, the openings 2d of FIGS. 13g to 131 den

correspond, i.e. In these exemplary embodiments, the openings 2d are designed as a large bore, as an elongated hole and in an octagonal shape. FIGS. 14 show housing parts 3 with an eccentric receptacle 3ah.

In contrast to the housing parts 3 of FIG. 6, the housing parts 3 of FIG. 14 have an eccentric rear receptacle 3ah, i.e. the axis Aa of the receptacle 3ah is offset from the axis Ag of the housing. The eccentric receptacle 3ah in FIGS. 14 is complementary to

eccentric receptacle 2av of the profile part 2p from Figures 13 is formed.

FIGS. 15 and 16 show short and long extension parts 5 with eccentric front receptacle 5av and eccentric rear receptacle 5ah, ie the axis Aa of the respective receptacle is offset from the axis Ag of the housing. The eccentric front receptacle 5av is designed like the eccentric front receptacle 2av of the profile part from FIGS. The eccentric rear receptacle 5ah is designed like the eccentric rear receptacle 3ah of the housing part 3. The housing part 3 or the extension part 5 does not engage in the opening 2d of the profile part 2p. Only the rotating element, ie the clutch 4k of the insert 4 or the clutch of the rotor extension 5r, reach through

Breakthrough 2d of the profile part 2p. The opening 2d in the profile part 2p can preferably be formed with a larger diameter than the coupling 4k and / or the coupling of the rotor extension 5r. As a result, the couplings do not come into contact with the inner wall of the opening 2d, i.e. the rotating components and the inner wall of the opening 2d are spaced apart. The lack of friction of the clutch on the inner wall of the opening 2d enables the key in the insert 4 to move smoothly.

The locking cylinder device 1 is designed as a production kit, i.e. if required, the locking cylinder device 1 is composed of the individual components consisting of bridge 2, housing part 3, insert 4 and, if necessary, one or more extension parts 5. The components make it possible to lock the cylinder 1 according to the thickness of the door

assemble. Due to the possibility of the manufacturing kit

To design according to the conditions of the door, it is also possible to design the left and right side of the locking cylinder 1 with different lengths or even with only one housing part 3 with insert 4.

The previously described in connection with the figures

Exemplary embodiments are also provided in a modified form in such a way that for the construction and assembly of the locking cylinder with insertion rotor and

Insert stator instead of insert technology is non-insert technology is used, ie in the modified exemplary embodiments it is provided that the housing part is designed as a lock cylinder stator in which the lock cylinder rotor is inserted.
