Description

TECHNICAL FIELD

[0001] The invention relates to a cylinder lock assembly for forming a cylinder lock attached in a panel, such as a door. BACKGROUND

[0002] A standard cylinder lock comprises, among others, a lock housing and a carrier, in which a rotatable cylinder is accommodated. By rotating the cylinder, the carrier is rotated together with the cylinder. As the carrier is connected to, for example, a bolt, the cylinder lock is locked or unlocked. The cylinder can be an outer cylinder, which can only be rotated if the correct key is inserted in the outer cylinder. The cylinder can also be connected to an operating knob, with the help of which rotation of the cylinder can be caused. The key and the operating knob are usually moved manually. By rotating the key or the operating knob, the cylinder lock is locked or unlocked.

[0003] Due to the increase of home electronics in and around the house, so-called smart locks are on the rise. A smart lock is a lock that can be locked and unlocked automatically, for example by actuation of an electric motor, which causes rotation of the cylinder and the carrier connected thereto. The actuation can be realized, for example, by making use of a smartphone, which sends a wireless signal, whereby the electric motor is set in motion. When the smartphone, which has the correct NFC tag, is held close to the smart lock, the lock can thus be unlocked.

[0004] There are also smart operating units, which are solutions that can convert a traditional cylinder lock into a smart lock. The smart operating unit comprises, for example, a setting unit, which can be attached to the inside of the panel in which the cylinder lock is installed. In order to rotate the inner cylinder, which is located on the inside of the cylinder lock, a suitable key is inserted in the lock. The setting unit is placed above the key and is configured to rotate the key, whereby the cylinder lock is locked and / or unlocked. SUMMARY

[0005] A disadvantage of such a setting unit is that the key is permanently located in the inner cylinder. For some cylinder locks, the outer cylinder cannot be rotated when the key is located in the inner cylinder. If such a cylinder lock is provided with the above-mentioned setting unit, it is no longer possible to lock and unlock the cylinder lock from the outside using the key. This is obviously impractical and undesirable.

[0006] Therefore, there is a need for a cylinder lock which does not have this drawback. Such a lock is known per se, and is a lock with a so-called hotel function. When the guest of a hotel room is inside his room and leaves the key on the inside of the door of his room, the hotel staff can nevertheless operate the door from the outside using the key. For this purpose, the known cylinder lock is provided with a carrier coupling for the hotel function, such that when the key is inserted, the outer cylinder of the lock is non-rotatably coupled to the carrier, and that the carrier rotates with the key when the key is rotated. When the external key is not inserted, the outer cylinder is rotationally decoupled from the carrier, such that the carrier can be rotated unhindered by the rotation of the inner cylinder. Therefore, in this case, the guest inside the room can use the key to unlock the door of his room from the inside, even though the external key is not present in the outer cylinder of the lock.

[0007] However, the remaining problem is that in practice, there are many different types of doors with different thicknesses. It is not easy for an individual to find a suitable cylinder lock with the right length. Although there are also known adjustable length locks, for this purpose, the lock has to be disassembled to a considerable extent, which is often too much of a challenge for an individual.

[0008] Therefore, there is a need for a cylinder lock assembly from which a cylinder lock can be made, which can be locked and unlocked from the outside using a key, wherein the length of the cylinder lock can be simply adjusted by an individual to the thickness of the door on which the lock is to be installed.

[0009] For this purpose, the invention provides a cylinder lock assembly according to claim 1. More particularly, the invention provides a cylinder lock assembly for forming a cylinder lock which is attached in a panel such as a door, wherein the cylinder lock assembly comprises:

[0010] - an inner lock housing part with a first end and an opposite second end;

[0011] - an outer lock housing part;

[0012] - at least one bridge;

[0013] - a carrier;

[0014] - an outer cylinder;

[0015] - an inner cylinder;

[0016] - a carrier coupling;

[0017] - an operating knob;

[0018] - a set of lock housing extension parts,

[0019] wherein the cylinder lock made from the cylinder lock assembly is constructed by selecting the aforementioned parts as follows:

[0020] The inner lock housing part is connected with the outer lock housing part by means of a bridge piece;

[0021] The outer cylinder is accommodated in the outer lock housing part and is provided with a tumbler which is accommodated in the outer cylinder in a manner that is slidable in a radial direction, which tumbler impedes rotation of the outer cylinder in the absence of a key being inserted, and which tumbler slides in the radial direction in the presence of a key being inserted, so that the outer cylinder can be rotated relative to the outer lock housing part about the cylinder axis;

[0022] The inner cylinder is accommodated in the inner lock housing part in a manner that is rotatable about the cylinder axis and is non-rotatably coupled to the carrier at a first end of the inner cylinder;

[0023] The carrier is accommodated between the inner lock housing part and the outer lock housing part in a manner that is rotatable about the cylinder axis of the cylinder lock;

[0024] The carrier coupling is provided with a so-called hotel function, so that in the presence of a key being inserted, the outer cylinder is non-rotatably coupled to the carrier, and in the presence of the key being rotated, the carrier rotates therewith, and in the absence of a key being inserted, the outer cylinder is rotationally decoupled from the carrier, so that the carrier can be rotated unhindered by rotation of the inner cylinder;

[0025] The operating knob is non-rotatably coupled to a second end of the inner cylinder, opposite the first end, for rotating the inner cylinder;

[0026] A lock housing extension part, selected from a set of lock housing extension parts, is connected to the inner lock housing part at the second end of the inner lock housing part, to obtain a desired length of the inner lock housing part by means of the lock housing extension part, wherein the desired length can be adjusted by varying the number of lock housing extension parts selected from the set of lock housing extension parts and / or selecting a lock housing extension part having a desired thickness from the set of lock housing extension parts, wherein the lock housing extension part selected from the set of lock housing extension parts is located between the inner lock housing part and the operating knob.

[0027] Such a cylinder lock can be applied in combination with different panels, for example different thicknesses of doors, for example in replacement of an existing cylinder lock in those panels. A user can use a key to open the panel from the outside by inserting the key in the outer cylinder of the outer lock housing part. From the inside, the carrier can be rotated by rotating the operating knob. The operating knob can be operated by a smart operating unit, realized as a setting unit. The cylinder lock can then be operated as a smart lock, for example by holding a smartphone close to the smart lock. Due to the carrier coupling with the hotel function, the carrier can always be unlocked and locked by means of the operating knob coupled to the operating unit realized as a setting unit. When a user inserts a key in the lock from the outside, the coupling between the outer cylinder and the carrier is caused, and the key can be used to lock and unlock the lock from the outside in a conventional manner.

[0028] By means of the cylinder lock assembly according to the application, a variety of cylinder locks, i.e. cylinder locks having a variety of lengths, can be replaced, thereby making the face plate suitable for operation by an operating unit realized as a setting unit. By means of the lock housing extension part, a cylinder lock of the desired length can be constituted in a simple manner by suitably selecting the lock housing extension part, i.e. such that the length of the new cylinder lock corresponds to the length of the cylinder lock to be replaced. The desired length is obtained, which can be achieved simply by selecting a lock housing extension part of a suitable thickness. The thickness is to be understood as the dimension which the lock housing extension part has when viewed in the direction along the cylinder axis. The selection can comprise no lock housing extension part, one lock housing extension part or a plurality of lock housing extension parts. The selected lock housing extension part can be attached to the second end of the inner lock housing part, for example by means of screws. Such an attachment is relatively simple and can be performed by the consumer himself. For this purpose, it is not necessary to detach the inner lock housing part from the bridge piece. The fastening of the lock housing extension part takes place at the free, accessible second end of the inner lock housing part. Thus, this length adjustment can be performed simply by an individual.

[0029] A further detailed description of the application is described in the dependent claims, and in the following will be further elucidated on the basis of examples with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0034] In the following detailed description of the drawings, reference is made to the examples represented in the drawings by means of reference numerals. However, the embodiments described in the detailed description are not limited to the examples shown in the drawings, but can also be realized in a different manner than shown in the examples. Therefore, the embodiments described in the detailed description should also be read and understood without the reference numerals. The various embodiments which will be described in the following can be used in combination with each other or independently from each other.

[0035] Most generally, the application provides a cylinder lock assembly 10 for forming a cylinder lock 50 which is attached in a face plate, such as 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 a cylinder lock assembly 10 is represented in Figure 2 .

[0046] A cylinder lock 50 made of the cylinder lock assembly 10 is built by selecting the aforementioned parts as follows:

[0047] The inner lock housing part 12 is connected with the outer lock housing part 52 by means of the bridge;

[0048] The outer cylinder 56 is accommodated in the outer lock housing part 52 and is provided with a tumbler which is accommodated in the outer cylinder 56 in a way that it is slidable in a radial direction, the tumbler obstructing the rotation of the outer cylinder 56 in the case that a key is not inserted, and the tumbler sliding in the radial direction in the case that a key is inserted, so that the outer cylinder 56 is rotatable relative to the outer lock housing part 52 about the cylinder axis 16;

[0049] The inner cylinder 14 is accommodated in the inner lock housing part 12 in a way that it is rotatable about the cylinder axis 16 and is non-rotatably coupled with the carrier 54 at the first end of the inner cylinder 14;

[0050] The carrier 54 is accommodated between the inner lock housing part 12 and the outer lock housing part 52 in a way that it is rotatable about the cylinder axis 16;

[0051] The carrier coupling 45 comprises a so-called hotel function, so that in the case that a key is inserted, the outer cylinder 56 is non-rotatably coupled with the carrier 54 and in the case that the key is rotated, the carrier 54 rotates therewith, and in the case that a key is not inserted, the outer cylinder 56 is rotationally decoupled from the carrier 54, so that the carrier 54 is freely rotatable by rotation of the inner cylinder 14;

[0052] The operating knob 18 is non-rotatably coupled to the second end of the inner cylinder 14 opposite the first end, to rotate the inner cylinder 14;

[0053] A lock case extension selected from a set of lock case extension members 20 is connected to the inner lock case member 12 at the second end of the inner lock case member 12 to obtain an inner lock case member 12 of a desired length 22 through the lock case extension member 20. The desired length 22 can be adjusted by changing the number of lock case extension members 20 within the selection and / or by selecting lock case extension members 20 with a desired thickness from the set of lock case extension members 20. The lock case extension member selected from the set of lock case extension members 20 is located between the inner lock case member 12 and the operating knob 18.

[0054] An example of a cylindrical lock 50 constructed in this way is shown in Figure 1 , Figure 3 and Figure 4 middle.

[0055] By replacing existing cylindrical locks with a cylindrical lock 50 made of the cylindrical lock assembly 10 according to the invention, and by installing a smart operating unit on the operating knob 18 of the cylindrical lock assembly 10, a panel with a conventional lock can be converted into a panel with a smart lock. The cylindrical lock 50 can then be opened from the outside by inserting a suitable key into the outer cylinder 56 of the outer lock housing component 52 and rotating the key. Furthermore, the cylindrical lock 50 can be opened by activating the smart operating unit.

[0056] Because the desired length 22 of the cylinder lock 50 is variable, the cylinder lock 50 can be used to replace almost any conventional cylinder lock. An electronic operating unit, implemented as a setting unit, can be installed without placing the key inside the lock. Since the carrier coupling 45 with hotel functionality does not typically rotatably connect the outer cylinder 56 to the carrier 54, the electronic operating unit can always be used to unlock and lock the cylinder lock 50. A rotational connection occurs between the outer cylinder 56 and the carrier 54 only when the key is inserted into the outer cylinder 56, allowing the cylinder lock 50 to be manually locked or unlocked from the outside (i.e., using the key). In this case, the operating knob 18 located inside will simply rotate accordingly, a rotation permitted by the electronic operating unit since it is not powered at this time.

[0057] In this way, almost any conventional cylinder lock in a panel of any thickness can be replaced by a cylinder lock 50, which can be intelligently operated by an electronic operating unit implemented as a setting unit, constructed by a cylinder lock assembly 10, and has a suitable length that matches the panel thickness by selecting a suitable lock case extension member 20.

[0058] Other effects and advantages of the cylindrical lock assembly 50 have been described in the invention summary and are hereby incorporated by reference.

[0059] In one embodiment, the lock case extensions 20 from a set of lock case extensions 20 have different thicknesses. This thickness is the dimension of the lock case extension 20 as viewed along the cylindrical axis 16. By combining these different thicknesses, the number of possibilities for varying the desired length 22 is increased. By cleverly selecting the differences, any desired length 22 within a defined range can be obtained. Examples of different thicknesses for the lock case extensions 20 from a set of lock case extensions 20 are 1 mm, 2 mm, 4 mm, and 8 mm. Therefore, by a suitable combination of the lock case extensions 20, each length of the lock case extension 20 can be made from 0 to 15 mm in 1 mm increments. Thus, the desired length 22 can vary in 15 mm increments.

[0060] In one embodiment, the inner lock housing component 12 and the selected lock housing extension component 20 are connected to each other by lock housing screws 28. The inner lock housing component 12 may be provided with a screw hole 30 to receive the lock housing screws 28. The cylinder lock assembly 10 may include a set of lock housing screws 28 with different lengths, and one of the lock housing screws 28 is used in the cylinder lock 50 according to the desired length obtained by the selected lock housing extension component 20.

[0061] To enable secure fastening of the lock case extension 20, the lock case extension 20 may be provided with a screw feed hole 40. An example of this is shown in... Figure 2 As shown in the diagram, the lock case screw 28 can be inserted through one or more screw feed holes 40 of one or more lock case extensions 20 and tightened into the screw hole 30 of the inner lock case component 12. This achieves a secure, reversible connection between the inner lock case component 12 and one or more lock case extensions 20.

[0062] In one embodiment, the cylindrical lock assembly 10 further includes a connecting rod 32 to provide a non-rotatable connection between the operating knob 18 and the inner cylinder 14. A first end of the connecting rod 32 is non-rotatably connected to the operating knob 18. A second end of the connecting rod 32 is non-rotatably connected to the inner cylinder 14. In the example shown, the connecting rod 32 has a rectangular cross-section. The first end of the connecting rod 32 is inserted into a slot 34 in the operating knob 18, and the opposite second end of the connecting rod is inserted into a slot 36 in the inner cylinder 14. The connecting rod 32 may be provided with a weak region 38 to break at a length matching the aforementioned desired length 22.

[0063] The connecting rod 32 may have a pin hole 42 at its end extending into the groove 36 in the inner cylinder 14. The inner cylinder 14 may have a pin 44 that extends through the pin hole 42 if the connecting rod 32 extends into the groove 36 in the inner cylinder 14. This creates a 'pin in hole' connection, which impedes movement of the connecting rod 32 in the longitudinal direction (i.e., parallel to the cylinder axis 16).

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

[0065] like Figure 1 and Figure 2 As shown, the profile can be a regular hexagon. The hexagonal profile can be easily connected to an electronic operating unit implemented as a setting unit.

[0066] In one embodiment, such as Figure 1 and Figure 2 As shown, at least one bridging member 24 of the cylindrical lock assembly 10 includes a set of bridging members 24 with different lengths. The bridging member 24 of the cylindrical lock 50 made of the cylindrical lock assembly 10 is selected from the set of bridging members 24.

[0067] Bridging member 24 connects inner lock housing component 12 to outer lock housing component 52, with carrier 54 housed between the inner lock housing component 12 and outer lock housing component 52. Based on the desired distance from carrier 54 to the outer side of the panel housing cylinder lock 50, a bridging member 24 matching this distance can be selected from a set of bridging members 24.

[0068] In one embodiment, as illustrated in the accompanying drawings, the cylinder lock assembly 10 may further include a set of extension connectors 58. A cylinder lock 50 made from the cylinder lock assembly 10 may include zero or more extension connectors 58 selected from the set of extension connectors 58. The selected extension connectors 58 are received between a carrier 54 and an outer lock housing component 52, wherein an outer cylinder 56 is received within the outer lock housing component 52. The selected zero or more extension connectors 58 are matched to the length of the bridging member 24 selected for the cylinder lock 50, and thus to the distance between the carrier 54 and the outer side of the door or panel where the cylinder lock 50 is to be received.

[0069] In one embodiment, as illustrated in the accompanying drawings, the inner locking housing 12 may be provided with a bridging screw hole 26 to attach the inner locking housing 12 to the bridging member 24. Similarly, the outer locking housing 52 may be provided with a bridging screw hole to attach the outer locking housing 52 to the bridging member 24. Thus, the inner locking housing 12 and the outer locking housing 52 can be easily connected to the bridging member 24 with a suitable selected length, even by an individual.

[0070] In one embodiment, an example of which is shown in the accompanying drawings, the carrier coupling 45 may include a coupling disc 46, which is forced to disengage from the carrier under the influence of the spring action of the spring 48, and, when the key is inserted, the coupling disc 46 is displaced in an axial direction along the direction of the carrier 54 to counteract the spring action, thereby achieving a non-rotatable connection between the outer cylinder 56 and the carrier 54.

[0071] As a result, the carrier 54 is normally rotatably separated from the outer cylinder 56, allowing the electronic operating unit to rotate the carrier 54. A rotational connection is only created between the outer cylinder 56 and the carrier 54 when a key is inserted into the outer cylinder 56, allowing the carrier 54 to be rotated using the key to lock or unlock the lock.

[0072] In one embodiment, when viewed along the axis of the cylinder, the inner locking housing component 12 has a substantially unchanged profile. When viewed along the axis of the cylinder, each of the set of locking housing extensions 20 has a substantially unchanged profile corresponding to the profile of the inner locking housing component 12.

[0073] In one embodiment, as shown, when viewed along the axis of the cylinder, the inner locking housing 12 has a substantially unchanged profile. Similarly, when viewed along the axis of the cylinder, the outer locking housing 52 also has a substantially unchanged profile. The profile of the outer locking housing 52 corresponds to the profile of the inner locking housing 12, and the profiles of the two housings 12 and 52 are aligned with each other.

[0074] Because the profiles correspond to each other and are in a straight line, the cylinder lock 50 can be easily installed or secured in an existing cylinder lock opening in the panel. For example, the profile can be a Euro profile. The Euro profile has standardized dimensions, which makes the cylinder lock 50 constructed from the cylinder lock assembly 10 usable as a replacement for cylinder locks from different manufacturers.

[0075] This invention is not limited to the examples shown in the accompanying drawings. As already indicated, the above embodiments can also be implemented in ways different from those shown in the examples in the drawings. The scope of protection is defined by the appended claims, in which the reference numerals are not limiting.
