DETAILED DESCRIPTION OF THE FIGURES

[0034] In the following detailed description of the figures, with the aid of reference numerals, reference is made to the example that is represented in the figures. The embodiments that are described in the detailed description, however, are not limited to the example that is shown in the figures but may also be implemented in a different way than shown in the example. The embodiments described in the detailed description should therefore be read and understood also without the reference numerals. The various embodiments to be described hereinafter can be used in combination with each other or independently of each other.

[0035] Most generally, the invention provides a cylinder lock assembly 10 for forming a cylinder lock 50 for attachment in a panel, such as, e.g., a door. The cylinder lock assembly 10 comprises: [0036] an inner lock housing part 12 having a first end and an opposite second end; [0037] an outer lock housing part 52; [0038] at least one bridge 24; [0039] a carrier 54; [0040] an outer cylinder 56; [0041] an inner cylinder 14; [0042] a carrier coupling 45; [0043] an operating knob 18; [0044] a set of lock housing extension parts 20.

[0045] An example of the cylinder lock assembly 10 is represented in FIG. 2.

[0046] The cylinder lock 50 which is made from the cylinder lock assembly 10 is built up from a selection of the aforementioned parts as follows: [0047] the inner lock housing part 12 is connected with the outer lock housing part 52 with the aid of the bridge; [0048] the outer cylinder 56 is received in the outer lock housing part 52 and is provided with lock pins received therein in a manner slidable in radial direction, which lock pins, with key non-inserted, hinder rotation of the outer cylinder 56 and, with key inserted, are slid in radial direction, so that the outer cylinder 56 is rotatable around a cylinder axis 16 relative to the outer lock housing part 52; [0049] the inner cylinder 14 is received in the inner lock housing part 12 in a manner rotatable around the cylinder axis 16 and at a first end thereof is non-rotatably coupled with the carrier 54; [0050] the carrier 54 is received between the inner lock housing part 12 and the outer lock housing part 52 in a manner rotatable around the cylinder axis 16; [0051] the carrier coupling 45 includes a so-called hotel functionality, so that, with key inserted, the outer cylinder 56 is non-rotatably coupled with the carrier 54 and upon rotation of the key the carrier 54 rotates along and, with key non-inserted, the outer cylinder 56 is rotationally uncoupled from the carrier 54 so that the carrier 54 is unhinderedly rotatable by rotation of the inner cylinder 14; [0052] the operating knob 18 is non-rotatably coupled to a second end, opposite the first end, of the inner cylinder 14 for the purpose of rotating the inner cylinder 14; [0053] a selection from the set of the lock housing extension parts 20 is connected with the inner lock housing part 12 at the second end of the inner lock housing part 12 in order to obtain a desired length 22 of the inner lock housing part 12 with the lock housing extension parts 20, wherein this desired length 22 is adaptable by changing the number of lock housing extension parts 20 within the selection and/or selecting a lock housing extension part 20 having a desired thickness from the set of lock housing extension parts 20, wherein the selection from the set of the lock housing extension parts 20 is positioned between the inner lock housing part 12 and the operating knob 18.

[0054] An example of a thus built-up cylinder lock 50 is represented in FIGS. 1, 3 and 4.

[0055] By replacing an existing cylinder lock with a cylinder lock 50 which is made from a cylinder lock assembly 10 according to the present invention and by mounting on the operating knob 18 thereof a smart operating unit, a panel with a conventional lock can be converted to a panel with a smart lock. The cylinder lock 50 is then openable from the outside by inserting a fitting key into the outer cylinder 56 of the outer lock housing part 52 and rotating it. Moreover, the cylinder lock 50 is openable by activating the smart operating unit.

[0056] Due to the desired length 22 of the cylinder lock 50 being variable, the cylinder lock 50 can be used in replacement of virtually any conventional cylinder lock. Mounting an electronic operating unit implemented as a set-up unit is possible without the key then needing to be placed in the inner side of the lock. Because the carrier coupling 45 with hotel functionality normally does not rotationally couple the outer cylinder 56 with the carrier 54, the cylinder lock 50 can always be unlocked and locked with the electronic operating unit. Only when a key is inserted into the outer cylinder 56 does a rotational coupling between the outer cylinder 56 and the carrier 54 come about, so that it is possible to lock or unlock the cylinder lock 50 from the outside manually, that is, with a key. Under that circumstance, the operating knob 18 on the inner side will simply rotate along and the electronic operating unit allows this because it is not energized at that moment.

[0057] In this manner, virtually any conventional cylinder lock in a panel of any thickness can be replaced with the cylinder lock 50, smartly operable with an electronic operating unit implemented as a set-up unit, which has been built up from the cylinder lock assembly 10 and, through selection of the right lock housing extension parts 20, has a right length matching the thickness of the panel.

[0058] The other effects and advantages of the cylinder lock assembly 50 have already been described in the summary and these effects and advantages are considered inserted here by reference.

[0059] In an embodiment, the lock housing extension parts 20 from the set of lock housing extension parts 20 have mutually different thicknesses. The thickness is the dimension of the lock housing extension part 20 viewed in the direction of the cylinder axis 16. By combining the mutually different thicknesses, the number of possibilities of varying the desired length 22 is augmented. By cleverly choosing the mutual differences, it is possible to obtain any desired length 22 within a defined range. An example of different thicknesses of lock housing extension parts 20 from the set of lock housing extension parts 20 is 1, 2, 4, and 8 mm. Through the right combination of lock housing extension parts 20, it is thus possible in steps of 1 mm to make each length from 0 through 15 mm of the lock housing extension parts 20. The desired length 22 can thus be varied with 15 mm.

[0060] In an embodiment, the inner lock housing part 12 and the selection of lock housing extension parts 20 are connected with each other by means of a lock housing screw 28. The inner lock housing part 12 may be provided with a screw hole 30 for receiving the lock housing screw 28. The cylinder lock assembly 10 may comprise a set of lock housing screws 28 of different lengths, one of which is used in the cylinder lock 50 depending on the desired length obtained by the selection of the lock housing extension parts 20.

[0061] To be able to fasten lock housing extension parts 20, they may be provided with a screw feed-through aperture 40. An example of this is shown in FIG. 2. The lock housing screw 28 can be inserted through the screw feed-through aperture 40 or screw feed-through apertures 40 of the one or more lock housing extension parts 20 and be screwed tight in the screw hole 30 of the inner lock housing part 12. Thus a strong, reversible connection of the inner lock housing part 12 with the lock housing extension part 20 or lock housing extension parts 20 comes about.

[0062] In an embodiment, the cylinder lock assembly 10 further comprises a coupling bar 32 for realization of the non-rotatable connection between the operating knob 18 and the inner cylinder 14. A first end of the coupling bar 32 is non-rotatably connected with the operating knob 18. A second end of the coupling bar 32 is non-rotatably connected with the inner cylinder 14. In the example shown, the coupling bar 32 has a rectangular cross section. The first end of the coupling bar 32 is inserted into a slot 34 in the operating knob 18 and a second, opposite end of the coupling bar is inserted into a slot 36 of the inner cylinder 14. The coupling bar 32 may be provided with weakened zones 38 for breaking off the coupling bar 32 at a length that matches the desired length 22 mentioned.

[0063] The coupling bar 32, at the end that extends into the slot 36 in the inner cylinder 14, may be provided with a pin hole 42. The inner cylinder 14 may be provided with a pin 44 which, if the coupling bar 32 extends into the slot 36 in the inner cylinder 14, extends through the pin hole 42. This creates a pin-in-hole connection which hinders a movement of the coupling bar 32 in longitudinal direction, i.e., parallel to the cylinder axis 16.

[0064] In an embodiment, the operating knob 18 has a hexagonal profile in a plane perpendicular to the cylinder axis 16.

[0065] As shown in FIGS. 1 and 2, the profile can be a regular hexagon. A hexagonal profile can be simply coupled with an electronic operating unit implemented as a set-up unit.

[0066] In an embodiment, as shown in FIGS. 1 and 2, the at least one bridge 24 of the cylinder lock assembly 10 comprises a set of bridges 24 of different lengths. The bridge 24 of the cylinder lock 50 made from the cylinder lock assembly 10 is selected from the set of bridges 24.

[0067] The bridge 24 connects the inner lock housing part 12 with the outer lock housing part 52, the carrier 54 being received between the inner lock housing part 12 and the outer housing lock part 52. Depending on the desired distance from the carrier 54 to the outer side of the panel in which the cylinder lock 50 is received, the bridge 24 which matches that distance can be selected from the set of bridges 24.

[0068] In an embodiment, an example of which is shown in the figures, the cylinder lock assembly 10 can further comprise a set of extension coupling pieces 58. The cylinder lock 50 made from the cylinder lock assembly 10 can comprise a selection of zero or more extension coupling pieces 58 from the set of extension coupling pieces 58. The selection of extension coupling pieces 58 is received between the carrier 54 and the outer lock housing part 52 with the outer cylinder 56 received therein. The selection of zero or more extension coupling pieces 58 matches the length of the bridge 24 selected for the cylinder lock 50 and hence matches the distance between the carrier 54 and the outer side of the door or the panel in which the cylinder lock 50 is to be received.

[0069] In an embodiment, an example of which is shown in the figures, the inner lock housing part 12 may be provided with a bridge screw hole 26 for attachment of the inner lock housing part 12 to the bridge 24. Similarly, the outer lock housing part 52 may be provided with a bridge screw hole for attachment of the outer lock housing part 52 to the bridge 24. Thus the inner lock housing part 12 and the outer lock housing part 52 can simply, even by a private individual, be connected with the bridge 24 of suitably chosen length.

[0070] In an embodiment, an example of which is shown in the figures, the carrier coupling 45 can comprise a coupling disc 46 which is forced out of engagement with the carrier under the influence of spring action by a spring 48 and which, with key inserted, is displaced, against spring action, in axial direction in the direction of the carrier 54 and thus realizes a non-rotatable coupling between the outer cylinder 56 and the carrier 54.

[0071] In consequence of this, the carrier 54 is generally rotationally uncoupled from the outer cylinder 56, so that the electronic operating unit can rotate the carrier 54. Only when a key is inserted into the outer cylinder 56 does a rotational coupling come about between the outer cylinder 56 and the carrier 54 and can the carrier 54 be rotated with the key and hence the lock be locked or unlocked.

[0072] In an embodiment, the inner lock housing part 12, viewed in the direction of the cylinder axis, has a substantially constant profile. Each lock housing extension part 20 of the set of lock housing extension parts 20, viewed in the direction of the cylinder axis, has a substantially constant profile which corresponds to the profile of the inner lock housing part 12.

[0073] In an embodiment, as shown in the figures, the inner lock housing part 12, viewed in the direction of the cylinder axis, has a substantially constant profile. The outer lock housing part 52, viewed in the direction of the cylinder axis, also has a substantially constant profile. The profile of the outer lock housing part 52 corresponds to the profile of the inner lock housing part 12 and the profiles of the two lock housings 12, 52 are in line with each other.

[0074] Due to the profiles being correspondent and in line with each other, the cylinder lock 50 can be simply mounted or fastened in the existing cylinder lock opening in a panel. The profile can be, e.g., a Euro profile. A Euro profile has standardized dimensions, which makes it possible for a cylinder lock 50 built up from the cylinder lock assembly 10 to be used in replacement of cylinder locks from different manufacturers.

[0075] The invention is not limited to the examples shown in the figures. The above described embodiments, as already indicated, may also be implemented differently than shown in the examples of the figures. The scope of protection is defined by the appended claims in which the reference numerals have no limiting effect.
