Abstract

The cylinder lock can be simply assembled and disassembled. The cylinder lock has a cylindrical housing, a bridge, and a cam. In the cylindrical housing, the first lock pin is fixedly received in the lock pin hole. The locking pin transversely passes through a cylindrical recess in the cylindrical housing. The first cylindrical end portion of the bridge portion is provided with a locking pin recess and a flat side extending from at least a free end portion of the first cylindrical end portion of the bridge portion away from a central portion of the bridge portion to the first locking pin recess and including the first locking pin recess. By inserting the first cylindrical end of the bridge into a cylindrical recess in the cylindrical housing and by rotating the bridge by an angle, the bridge may be simply connected with the cylindrical housing such that the locking pin extends in a locking pin recess in the bridge. Afterwards, the assembled whole can be locked through a locking bolt.

Description

Technical Field

[0001] The present invention relates to a cylinder lock and a method for assembling such a cylinder lock. Background Art

[0002] The applicant currently sells a lock according to the preamble of claim 1. In this regard, see for example the YouTube video uploaded on November 26, 2021:

[0003] https: / / www.youtube.com / watch?v=tl_bnF85jNQ

[0004] Figures 1 to 3 An example of such a cylinder lock is shown. The known lock comprises a first cylindrical housing 12. Although Figure 4 The cylindrical housing according to an example of the present invention is shown, but for the following description of the known cylinder lock, it is recommended to consider Figure 4 The only difference between the known cylindrical shell and the new cylindrical shell is in fact the presence of a fixed locking pin 38 in the new cylindrical shell, whereas in the known cylindrical shell this is a removable locking pin 38. The known cylindrical shell 12 comprises a first cylindrical recess 14 extending along a first axis L1 and a second cylindrical recess 16 extending along a second axis L2 parallel to the first axis L1. The first cylindrical recess 14 and the second cylindrical recess 16 extend from an end 12a of the first cylindrical shell 12. The first cylindrical shell 12 also comprises a first locking pin hole 18 extending perpendicularly to the second axis L2 and partially extending through the second cylindrical recess 16. The axis L3 of the first locking pin hole 18 does not intersect the second axis L2, so that the first locking pin hole 18 is offset relative to the second axis L2. The first cylindrical shell 12 comprises a locking bolt hole 20 with an internal thread extending perpendicularly to the second axis L2.

[0005] The known cylinder lock 10 further comprises a first lock cylinder 22 which is rotatably received in a first cylindrical recess 14 in the first cylindrical housing 12 about a first axis L1 in an unlocked state and which is non-rotatably received in a locked state in the first recess 14. A cam 24 is coupled to the first lock cylinder 22 or can be coupled thereto.

[0006] Furthermore, the cylinder lock 10 comprises a bridge 28', which comprises a central portion 30' and a first cylindrical end 32'. The first cylindrical end 32' extends along a bridge axis L4 and is removably accommodated in a second cylindrical recess 16 in the first cylindrical housing 12. The first cylindrical end 32' of the bridge 28' is provided with a single first locking pin recess 34', which extends along a first locking pin recess axis L5, which is perpendicular to the bridge axis L4 and coaxial with the axis L3 of the first locking pin hole 18 when the bridge 28' and the first cylindrical housing 12 are connected to each other. Furthermore, the bridge 28' is provided with a first locking bolt channel 36', which has an axis L6 extending perpendicular to the bridge axis L4. In the assembled state, the first locking pin 38 is accommodated in the first locking pin hole 18 in the first cylindrical housing 12. When the bridge 28 and the first cylindrical housing 12 are connected to each other, the first locking pin 38 extends in the first locking pin recess 34 of the bridge 28. The cylinder lock 10 further comprises a first locking bolt 40 by means of which the bridge 28 and the first cylindrical housing 12 are detachably connected.

[0007] Known cylinder locks may have a single cylindrical housing 12. In this case, the lock can only be operated with a key from one side of the door. However, it may also involve two cylindrical housings. Figures 1 to 3An example of two cylindrical shells is shown. In this case, the known cylinder lock 10 includes a second cylindrical shell 112, which is provided with a third cylindrical recess 114 extending along the first axis L1 and a fourth cylindrical recess 116 extending along the second axis L2. The third cylindrical recess 114 and the fourth cylindrical recess 116 extend from the end 112a of the second cylindrical shell 112. The second cylindrical shell 112 is also provided with a second locking pin hole 118, which extends perpendicularly to the second axis L2 and partially extends through the fourth cylindrical recess 116. The axis L9 of the second locking pin hole 118 does not intersect the second axis L2, so that the second locking pin hole 118 is offset relative to the second axis L2. The second cylindrical shell 112 is provided with a second locking bolt hole 120 with an internal thread extending perpendicularly to the second axis L2. The known cylinder lock with two cylindrical housings 12, 112 is also provided with a second lock cylinder 122, which is rotatably accommodated in a third cylindrical recess 114 in the second cylindrical housing 112 around the first axis L1 in the unlocked state, and which is non-rotatably accommodated in the third recess 114 in the locked state. In this embodiment of the known cylinder lock, the cam 24 is also coupled to the second lock cylinder 122 or can also be coupled to the second lock cylinder. The bridge 28' is provided with a second cylindrical end 44', which extends from the central part 30' of the bridge 28' along the bridge axis L4 and away from the first cylindrical end 32'. The second cylindrical end 44' is detachably accommodated in a fourth cylindrical recess 116 in the second cylindrical housing 112. The second cylindrical end 44' of the bridge 28' is provided with a single second locking pin recess 46' extending along a second locking pin recess axis L7, which is perpendicular to the bridge axis L4 and coaxial with the axis L9 of the second locking pin hole 118 when the bridge 28' and the second cylindrical housing 112 are connected to each other. The bridge 28 is provided with a second locking bolt channel 48', which has an axis L8 extending perpendicular to the bridge axis L4. The known cylinder lock 10 is also provided with a second locking pin 138, which is fixedly accommodated in the second locking pin hole 118 in the second cylindrical housing 112 and extends in the second locking pin recess 46' of the bridge 28' when the bridge 28 and the second cylindrical housing 112 are connected to each other. The bridge 28 is detachably connected to the second cylindrical housing 112 by means of a second locking bolt 140.

[0008] The known cylinder lock 10 can be equipped with a bridge 28' of different lengths. A filler piece can then be arranged between the first cylindrical housing 12 and the cam 24 and between the second cylindrical housing 112 and the cam 24, the filler piece having the same circumferential profile as the ends 12a, 112a of the first and second cylindrical housings 12, 112, respectively. For this, see the aforementioned YouTube video. Thus, the length of the cylinder lock can be adapted to the thickness of the door in which the cylinder lock 10 is assembled. Summary of the invention

[0009] Although the known cylinder locks are very satisfactory in practice, the assembly of the cylinder locks requires necessary flexibility. As can be seen in the aforementioned YouTube video, first, the cylindrical end 32 is inserted into the second recess. Then, the locking pin 38 is pressed into the locking pin hole 18, and the locking pin establishes a connection between the bridge 28' and the first cylindrical housing 12. The connection is then fixed by arranging and tightening the locking bolt 40 in the locking bolt hole 20. When it comes to a cylinder lock 10 with two cylindrical housings 12, 112, this assembly sequence also applies to the connection of the second cylindrical housing 112 to the bridge 28'. Similarly, first, the second cylindrical end 44' is inserted into the fourth recess 116, and then, the second locking pin 138 can be pressed into the second locking pin hole 118. Before the first locking pin 38 and / or the second locking pin 138 are arranged, the associated cylindrical housing 12, 112 can be rotated relative to the bridge 28' and the position of the associated cylindrical housing 12, 122 relative to the other components of the cylinder lock 10 (such as the cam 24 and any filler) is unstable. In the case of an unstable assembly of the components, the locking pin 38, 138 should be fitted in the locking pin hole 18, 118, and in order to achieve this, the bridge 28' must also be aligned so that the locking pin 38, 138 can also pass through the locking pin recess 34', 46'. This requires great dexterity from the person assembling the lock, and an individual only needs to do it a few times before finding the assembly difficult.

[0010] The invention contemplates providing a cylinder lock of the type described in the preamble of claim 1 which can be assembled and disassembled in a simple manner. To this end, the known cylinder lock is characterized in that the first locking pin is fixedly accommodated in the locking pin hole and the first cylindrical end of the bridge is provided with a flat side which extends at least from a free end of the first cylindrical end of the bridge remote from the central part of the bridge to and includes the first locking pin recess. The flat side extends in a plane which is at an angle to the axis of the first locking pin recess, so that when the first cylindrical end is inserted into the second recess in a first rotational position of the bridge relative to the first cylindrical housing, the first cylindrical end can at least partially pass through the first locking pin due to the presence of the flat side. After the first cylindrical end has been fully inserted into the second recess, the bridge can be rotated relative to the first cylindrical housing into a second rotational position in which the first locking pin is accommodated in the first locking pin recess, so that a displacement of the bridge relative to the first cylindrical housing in an axial direction along the second axis is blocked. In this second rotational position, the first locking bolt channel in the bridge portion and the first locking bolt hole in the first cylindrical shell are coaxially oriented so that the first locking bolt in the assembled state detachably connects the first cylindrical end of the bridge portion and the first cylindrical shell to each other.

[0011] The cylinder lock according to the invention does not require the locking pin to be arranged in the locking pin hole of a still unstable assembly, because the parts of the assembly can still be moved relative to each other and can be separated from each other, while the cylinder lock according to the invention only requires the first cylindrical end to be inserted into the second cylindrical recess and then rotated to the second rotational position to fix the axial displacement of the first cylindrical shell relative to the bridge. Thereafter, it is only necessary to hinder the rotation of the first cylindrical shell relative to the bridge. This can be achieved simply by arranging and tightening the locking bolt. Therefore, the assembly of the cylinder lock becomes simpler, even to the extent that an inexperienced end user or individual can also assemble the lock. In addition, the disassembly of the cylinder lock according to the invention is simpler than the disassembly of the known cylinder lock. It is only necessary to loosen the locking bolt, after which the bridge is rotated 90° so that the first cylindrical shell can be removed from the bridge. This operation can be performed in a simple manner and the possibility of damage to the cylinder lock is very small.

[0012] The present invention also provides a method for assembling the cylinder lock according to the present invention. The method comprises:

[0013] Providing a cylinder lock according to the present invention;

[0014] inserting the first cylindrical end of the bridge into the second cylindrical recess of the first cylindrical housing when the bridge is in a first rotational position relative to the first cylindrical housing, wherein the first cylindrical end can at least partially pass through the first locking pin due to the presence of a flat side on the first cylindrical end;

[0015] After the first cylindrical end portion is fully inserted into the second recess, the bridge portion is rotated relative to the first cylindrical housing to a second rotational position in which the first locking pin is received in the first locking pin recess so that displacement of the bridge portion relative to the first cylindrical housing in an axial direction along the second axis is blocked, wherein in the second rotational position the first locking bolt passage in the bridge portion and the first locking bolt hole in the first cylindrical housing are coaxially oriented, and

[0016] The first locking bolt is installed whereby it extends through the first locking bolt passage in the bridge portion and engages the internal thread in the first locking bolt hole in the first cylindrical shell so that the first cylindrical end of the bridge portion and the first cylindrical shell are removably connected to each other.

[0029] Figures 1 to 3 The cylinder lock 10 shown is known from practice and is described in detail in the background of the present application. When assembling the known cylinder lock 10, first, the first cylindrical end 32 is inserted into the second recess 16 (see Figure 4 ), the locking pin 38 is then pressed into the locking pin hole 18. It is not easy to arrange the locking pin 38 in the locking pin hole 18, because the first cylindrical shell 12 can rotate relative to the bridge 28', and further, the first cylindrical shell can be displaced in the axial direction relative to the bridge 28'. In addition, the cam 24 and any filler must also be kept in place. This requires great dexterity and experience. In fact, in order to arrange the locking pin 38, it is also necessary to align the locking pin recess 34' with the locking pin hole 18 in the first cylindrical shell by appropriate rotation of the bridge 28'. Figure 2 A known cylinder lock 10 is shown partially assembled. All parts are still unstable relative to each other and must be held in the correct position by hand. A stable whole is not provided until the locking pins 38, 138 are arranged in the corresponding locking pin holes 18, 118.

[0030] Using the cylinder lock 10 according to the present invention (an example of the cylinder lock is shown in Figures 7 to 11 ), the assembly problem is greatly alleviated, so that the assembly of the cylinder lock 10 becomes much simpler. Simple enough for a private end user to do it.

[0031] The cylinder lock 10 is provided with at least one cylindrical housing 12 , 112 . Figure 4The view of FIG. 1 clearly shows the end 12a of the first cylindrical housing 12, the first cylindrical recess 14 extending along the first axis L1, and the second cylindrical recess 16 extending along the second axis L2. The first cylindrical housing 12 is also provided with a first locking pin hole 18, which extends perpendicularly to the second axis L2 and partially extends through the second cylindrical recess 16. In addition, the locking bolt hole 20 with an internal thread is clearly visible, which is engaged with the locking bolt 40 in the installed state. In addition, in Figure 4 As can be clearly seen in FIG. 1 , the locking pin 38 has been accommodated in the locking pin hole 18 of the first cylindrical housing 12. During disassembly, the locking pin 38 is not intended to be removed from the locking pin hole 18. According to the present invention, the locking pin 38 is fixedly accommodated in the locking pin hole 18.

[0032] The second cylindrical shell 112 is implemented in the same manner as the first cylindrical shell 12. Only the naming and reference numerals of the second cylindrical shell 112 used hereinafter are different. For example, the second cylindrical shell 112 is provided with a third cylindrical recess 114, which corresponds to the first cylindrical recess 14 of the first cylindrical shell 12. The fourth cylindrical recess 116 of the second cylindrical shell 112 corresponds to the second cylindrical recess 16 of the first cylindrical shell 12. The end 112a of the second cylindrical shell 112 corresponds to the end 12a of the first cylindrical shell 12. In the case of the second cylindrical shell 112, the associated locking pin 138 is also fixedly accommodated in the locking pin hole 118.

[0033] like Figures 7 to 11 It can be clearly seen that the cylinder lock 10 is also provided with a first lock cylinder 22, which is rotatably accommodated in the first cylindrical recess 14 in the first cylindrical housing 12 about the first axis L1 in the unlocked state, and which is non-rotatably accommodated in the first recess 14 in the locked state. Unlocking of the rotation of the lock cylinder 22 is performed by inserting a key into the lock cylinder 22. Locking of the rotation of the lock cylinder 22 is performed by withdrawing the key from the lock. In addition, the cylinder lock 10 is provided with a cam 24, which is coupled to the first lock cylinder 22 or can be coupled thereto.

[0034] In the embodiment, an example of this embodiment is Figures 7 to 11 As shown in FIG. 1 , the cylinder lock 10 may also be provided with a second lock cylinder 122, which is rotatably accommodated in the third cylindrical recess 114 in the second cylindrical housing 112 around the first axis L1 in the unlocked state, and is non-rotatably accommodated in the third recess 114 in the locked state. In this embodiment, the cam 24 is coupled to the second lock cylinder 122 or can be coupled to the second lock cylinder.

[0035] Figure 5 and Figure 6 An example of a bridge 28 of a cylinder lock 10 according to the present invention is shown. Just like the known bridge 28' already described in the background art above, the bridge 28 of the cylinder lock 10 according to the present invention is provided with a central portion 30 and a first cylindrical end 32. The first cylindrical end 32 extends along the bridge axis L4 and is removably received in the second cylindrical recess 16 in the first cylindrical housing 12. The first cylindrical end 32 of the bridge 28 is provided with a single first locking pin recess 34 extending along a first locking pin recess axis L5 perpendicular to the bridge axis L4. Furthermore, the bridge 28 is provided with a first locking bolt channel 36 having an axis L6 extending perpendicular to the bridge axis L4.

[0036] According to the invention, the first cylindrical end 32 of the bridge 28 is provided with a flat side 42 extending from at least a free end 32a of the first cylindrical end 32 of the bridge 28 remote from the central portion 30 of the bridge 28 to and including the first locking pin recess 34. The flat side 42 extends in a plane at an angle to the first locking pin recess axis L5.

[0037] Figure 5 and Figure 6 The example of the bridge 28 shown relates to an embodiment of the invention, since it is destined to be connected to the first cylindrical housing 12 and the second cylindrical housing 112. In the most basic embodiment of the cylinder lock 10 according to the invention, the bridge 28 can also be embodied in connection with only a single cylindrical housing 12.

[0038] However, in the embodiment with two cylindrical shells 12, 112, the bridge 28 is additionally provided with a second cylindrical end 44 extending from the central portion 30 of the bridge 28 along the bridge axis L4 and away from the first cylindrical end 32. The second cylindrical end 44 is removably accommodated in a fourth cylindrical recess 116 in the second cylindrical shell 112. The second cylindrical end 44 of the bridge 28 is provided with a single second locking pin recess 46 extending along a second locking pin recess axis L7 perpendicular to the bridge axis L4. In this embodiment, the second cylindrical end 44 of the bridge 28 is also provided with a flat side 50 extending from at least a free end 44a of the second cylindrical end 44 of the bridge 28 away from the central portion 30 of the bridge 28 to and including the second locking pin recess 46. The flat side 50 extends in a plane at an angle to the second locking pin recess axis L7. The bridge portion 28 is provided with a second locking bolt channel 48 having an axis L8 extending perpendicularly to the bridge axis L4.

[0039] In the assembled state, the first locking pin 38 is accommodated in the first locking pin hole 18 in the cylindrical housing 12. When the bridge 28 and the first cylindrical housing 12 are connected to each other, the first locking pin 38 extends in the first locking pin recess 34 of the bridge 28. The cylinder lock 10 is also provided with a first locking bolt 40, by means of which the bridge 28 is detachably connected to the first cylindrical housing 12. In the assembled state, the first locking pin recess axis L5 of the first locking pin recess 34 is coaxial with the axis L3 of the first locking pin hole 18. In the illustrated embodiment with two cylindrical housings 12, 112, for the second locking pin recess axis L7 of the second locking pin recess 46, this second locking pin recess axis is also kept coaxial with the axis L9 of the second locking pin hole 118.

[0040] As already described in the summary of the invention, the present invention provides a cylinder lock 10 that can be simply assembled. Due to the above-described embodiment of the fixed locking pin 38, 138 and the specially implemented bridge 28 with the flat cylindrical end 32, 44, when the first cylindrical end 32 is inserted into the second recess 16 in the first rotational position of the bridge 28 relative to the first cylindrical housing 12, the first cylindrical end 32 can at least partially pass through the first locking pin 38. After the first cylindrical end 32 is fully inserted into the second recess 16, the bridge 28 can be rotated relative to the first cylindrical housing 12 to the second rotational position, in which the first locking pin 38 is accommodated in the locking pin recess 34, so that the displacement of the bridge 28 relative to the first cylindrical housing 12 in the axial direction along the second axis L2 is blocked. In this second rotational position, the first locking bolt channel 36 in the bridge portion 28 and the first locking bolt hole 20 in the first cylindrical shell 12 are coaxially oriented so that the first locking bolt 40 in the assembled state detachably connects the first cylindrical end 32 of the bridge portion 28 and the first cylindrical shell 12 to each other.

[0041] In a similarly simple manner, the second cylindrical shell 112 can also be connected to the bridge 28. Due to the presence of the flat side 50, when the second cylindrical end 44 is inserted into the fourth recess 116 at the first rotational position of the bridge 28 relative to the second cylindrical shell 112, the second cylindrical end 44 can at least partially pass through the second locking pin 138. After the second cylindrical end 44 is fully inserted into the fourth recess 116 of the second cylindrical shell 112, the bridge 28 can be rotated relative to the second cylindrical shell 112 to the second rotational position, in which the second locking pin 138 is accommodated in the second locking pin recess 46, so that the displacement of the bridge 28 relative to the second cylindrical shell 112 in the axial direction along the second axis L2 is blocked. In this second rotational position, the second locking bolt channel 48 in the bridge portion 28 and the second locking bolt hole 120 in the second cylindrical shell 112 are coaxially oriented so that the second locking bolt 140 in the assembled state can detachably connect the second cylindrical end 44 of the bridge portion 28 and the second cylindrical shell 112 to each other.

[0042] In the embodiment, an example of this embodiment is Figures 5 to 11 , the central portion 30 of the bridge 28 can have a flat side 52 that faces in the direction of the cam 24 and along which the cam 24 can pass through the bridge 28. This flat side 52 provides the possibility of giving the central portion 30 a slightly larger diameter without hindering the rotation of the cam 24.

[0043] As is clearly shown in the figures, the central part 30 of the bridge is provided with a channel 52, which is provided with an internal thread in a known manner. In this channel 52, a bolt can engage, by means of which the cylinder lock can be fixed in the door.

[0044] In the embodiment, an example of this embodiment is Figure 4 , Figures 7 to 11 , the first cylindrical housing 12 can be provided with a hole 54 having an internal thread in the end 12a of the first cylindrical housing. A similar hole 154 can also be provided in the end 112a of the second cylindrical housing 112. These holes 54, 154 can be used to install bolts in these holes, by means of which fillers can be attached to the respective first and second cylindrical housings 12, 112. The circumferential profile of these fillers preferably corresponds to the circumferential profile of the ends 12a, 112a of the first and second cylindrical housings 12, 112, respectively. When bridges 28 of different lengths are additionally provided, for example because the various bridges 28 each have a central portion 30 of different lengths, cylinder locks 10 of different lengths can be assembled from these components.

[0045] The following will refer to Figures 7 to 11 A method for assembling a cylinder lock according to the invention is further explained.

[0046] exist Figure 7 , the different components of the cylinder lock 10 are shown in an unassembled state. Note that the first locking pin 38 has been fixedly received in the locking pin hole 18 of the first cylindrical housing 12. The same applies to the second locking pin 138, which is fixedly received in the second locking pin hole 118 in the second cylindrical housing 112.

[0047] In a first operation, when the bridge 28 is in a first rotational position relative to the first cylindrical housing 12, the first cylindrical end 32 of the bridge 28 is inserted into the second cylindrical recess 16 of the first cylindrical housing 12. In this operation, due to the presence of the flat side 42 on the first cylindrical end 32, the first cylindrical end 32 can at least partially pass through the first locking pin 38.

[0048] In an embodiment with two cylindrical shells 12, 112, this first operation of the method further includes inserting the second cylindrical end 44 of the bridge 28 into the fourth recess 116 of the second cylindrical shell 112 when the bridge 28 is in the first rotational position relative to the second cylindrical shell 112. Also in this operation, due to the presence of the flat side 50 on the second cylindrical end 44, the second cylindrical end 44 can at least partially pass through the second locking pin 138.

[0049] exist Figure 8 , the following situation is shown: when the bridge portion 28 is in the first rotational position relative to the second cylindrical shell 112, the second cylindrical end portion 44 of the bridge portion is inserted into the fourth recess 116 of the second cylindrical shell 112.

[0050] Fig. 9 The step in which the first cylindrical end portion 32 of the bridge 28 is inserted into the second cylindrical recess 16 of the first cylindrical housing 12 is shown.

[0051] Fig.10 The bridge 28 is shown to have been rotated to a second rotational position relative to the first and second cylindrical shells 12, 112. In this second rotational position, the first locking pin 38 is received in the first locking pin recess 34, so that displacement of the bridge 28 relative to the first cylindrical shell 12 in the axial direction along the second axis L2 is blocked. In addition, the first locking bolt passage 36 in the bridge 28 and the first locking bolt hole 20 in the first cylindrical shell 12 are coaxially oriented.

[0052] In the embodiment with two cylindrical shells 12, 112, it is also considered that in this second rotational position, the second locking pin 138 is accommodated in the second locking pin recess 46, so that the displacement of the bridge 28 relative to the second cylindrical shell 112 in the axial direction along the second axis L2 is blocked. In this second rotational position, the second locking bolt channel 48 in the bridge 28 and the second locking bolt hole 120 in the second cylindrical shell 112 are also coaxially oriented.

[0053] Fig.11 Next, the assembled cylinder lock 10 is shown, having undergone the final steps, namely:

[0054] Installation of the first locking bolt 40 whereby the first locking bolt extends through the first locking bolt passage 36 in the bridge portion 28 and engages the internal threads in the first locking bolt hole 20 in the first cylindrical housing 12 such that the first cylindrical end portion 32 of the bridge portion 28 and the first cylindrical housing 12 are removably connected to each other; and

[0055] The second locking bolt 140 is installed, whereby the second locking bolt extends through the second locking bolt channel 48 in the bridge portion 28 and engages the internal thread in the second locking bolt hole 120 in the second cylindrical shell 112, so that the second cylindrical end 44 of the bridge portion 28 and the second cylindrical shell 112 are detachably connected to each other.

[0056] Furthermore, the disassembly of the cylinder lock 10 according to the invention is much simpler than the disassembly of the known cylinder locks. With the known cylinder locks 10, the locking pins 38, 138 have to be knocked out of the cylindrical housing 12, 112 using a punch. This is an operation that can be performed in a safe and stable manner practically only using a special support fixture and that, moreover, easily leads to damage to the cylindrical housing 12, 112. Moreover, an individual will not easily perform such an operation because he will be afraid of the damage he may cause to the cylinder lock 10. With the cylinder lock according to the invention, only the locking bolts 40, 140 need to be loosened and the bridge 28 rotated by 90° so that the first cylindrical housing 12 and the second cylindrical housing 112 can be removed from the bridge.
