Definitions
- the invention relates to a part of a modular lock cylinder.
- EP0874113 discloses a part of a modular lock cylinder according to the preamble of claim 1.
- Other lock cylinders with measures against attack by plug / cylinder extraction are known from CH 674543 or EP 0676517 .
- the present invention seeks to provide an improved part of a modular lock cylinder. According to the present invention, there is provided a part of a modular lock cylinder as specified in claim 1.
- a lock cylinder 100 and a lock case 104 may be placed in a door 102.
- a force 106 of an extraction attack is applied along a longitudinal axis of the lock cylinder 100, i.e. on a plane perpendicular to the surface area of the door 102.
- Figure 2 illustrates how the parts may be placed in the door 102.
- the lock case 104 may be pushed into a hollow from a side of the door 102, whereupon the lock cylinder 102 may be pushed through a hole 200 in the door 102.
- a hole 204 in the lock case 104 may accommodate a screw 202 that is screwed down into a hole 206 of the lock cylinder 100.
- FIGS 3 and 4 illustrate the placement of the lock cylinder 100 in relation to the lock case 104.
- the lock case 104 is made of two parts: a plate 306 and a case 308.
- the plate 306 comprises two holes 302, 304 accommodating two fastening screws with which the lock case 104 is bolted to the door 102.
- a lock bolt 300 is moved 310 in and out within a hole in the plate 306 and by a mechanism accommodated in the case 308.
- a movement 310 of the lock bolt 300 realizes a locking function: if the lock bolt 300 is in the hole in the plate 306, the lock is open, and if the lock bolt 300 protrudes from the hole in the plate 306, the lock is closed.
- the in and out movement 310 of the lock bolt 300 takes place along an axis perpendicular to the flat surface of the plate 306.
- Figure 5 illustrates an apparatus which is a part of a modular lock cylinder according to the invention.
- the apparatus comprises a slot 500 between a first support 502 and a second support 504.
- the first support 502 and the second support 504 may belong to a holder 506 forming the slot 500.
- the holder 506 may be U-shaped.
- the first support 502 may be one branch of the U-shaped holder 506, and the second support 504 may be the other branch, parallel with the first support 502.
- the slot 500 accommodates a lock bit 508 movable in the slot 500.
- the operation of the lock bit 508 will be explained in more detail, but it is a kind of a latch or a cam.
- the slot 500 may be implemented by any suitable means for accommodating the lock bit 508: as a suitable aperture, bore, cavity, chamber, groove, hole, hollow, opening, passage, or the like.
- the first support 502 and the second support 504 are to be understood as portions around the slot 500, they 'support' the lock bit 508 at least in the sense that they delimit the movement of the lock bit 508 within the slot 500.
- the lock bit 508 may be rotatable 514 in the slot 500 between a lock open position and a lock closed position.
- the lock closed position may be an initial position of the lock bit 508, i.e. 30 degrees in the counterclockwise direction
- the lock open position may be a final position of the lock bit 508 (drawn with a dotted line), i.e. 330 degrees in the counterclockwise direction.
- the apparatus comprises means 510 for transmitting a force 106 of an extraction attack against the apparatus from the first support 502 through the lock bit 508 to the second support 504. Without the means 510 for transmitting the force 106, the first support 502 would bend in the direction of the force 106. Owing to the means 510 for transmitting the force 106, however, the first support 502, the lock bit 508 and the second support 504 appear as if they were one solid piece, making the structure very strong, and the first support 502 will not bend. It is worth noticing that if the force 106 is applied from the opposite direction, the end result is the same: the second support 504 will not bend, as the force is transmitted from the second support 504 through the lock bit 508 to the first support 502.
- the means 510 for transmitting may be implemented as a mechanical coupling or couplings between the parts 502, 504, 508.
- the means 510 for transmitting may also be coupled to the lock case 104.
- the surface area of the case 308 is relatively large so as to distribute the force 106 of the extraction attack over a wide area.
- the lock case 104 is also coupled to the door 102 by screws in the holes 302 and 304. As the lock cylinder 100 is fitted within the lock case 104, torsion forces against the screw 202 in the hole 206 are small. Consequently, a force 512 is about the same as the force 106 of the extraction attack. The force 512 is transmitted from the means 510 for transmitting via the screw 202 to the lock case 104, so as to keep the means 510 for transmitting coupled to the lock case 104.
- the apparatus of Figure 5 is a part of a modular lock cylinder 100, such as the one illustrated in Figures 1, 2, 3, and 4 .
- the lock cylinder 100 may be an ordinary mechanical lock cylinder. Additionally, or alternatively, the lock cylinder 100 may be a self-powered electromechanical lock cylinder, such as the lock cylinders produced by iLoq, and protected by several EP applications: 05112272.9 , 07112677.5 , 07112676.7 , and 07112673.4 .
- Figures 6, 7, and 8 illustrate various configurations of the lock cylinder 100.
- Figure 6 illustrates the same configuration of the lock cylinder 100 as Figures 1, 2, 3, and 4 .
- the double cylinder 100 of Figure 6 comprises four parts:
- Figure 7 illustrates a second configuration. While Figure 6 illustrates a double cylinder, i.e. a lock cylinder that may be operated with a key from both sides of the door 102, Figure 7 illustrates a half cylinder 100, i.e. a lock cylinder that may be operated with a key only from one side of the door 102.
- the half cylinder 100 of Figure 7 comprises the following four parts:
- Figure 8 illustrates a third configuration, operable from the both sides of the door 102 but differing from the configuration of Figure 6 in that no key is needed for the operation from the other side of the door 102.
- the knob cylinder 100 of Figure 8 comprises the following four parts:
- Figure 9 illustrates a further embodiment of the apparatus of Figure 5 , where the central parts are in the middle: the holder 506 with the first support 502 and the second support 504, and the lock bit 508 in the slot 500.
- the force of the extraction attack against the apparatus comes along a longitudinal axis 960 of the apparatus, which corresponds with the force vector 106 illustrated in Figure 1 .
- the apparatus is also assembled along the axis 960.
- No means 510 for transmitting the force of the extraction attack against the apparatus from the first support 502 through the lock bit 508 to the second support 504 are illustrated with a single reference sign in Figure 9 .
- Figure 9 further shows the U-shaped holder 506. Since the first support 502, the lock bit 508, and the second support 504 move as one piece under the force of the extraction attack, the structure may actually become O-shaped.
- the means 510 for transmitting may comprise an interlocking mechanism, i.e. a mechanism that mechanically couples the first support 502, the lock bit 508, and the second support 504 together.
- the means 510 for transmitting may be positioned and dimensioned in such a manner that tolerances between said parts 502, 504, 508, 510 of the apparatus are closed under the force 106 of the extraction attack, and contacting surfaces 926, 932 (it is to be noted that there are also two further invisible contacting surfaces: one on the right-hand side of the first support 502, and the other on the right-hand side of the lock bit 508) of said parts 502, 504, 508, 510 of the apparatus bear on each other while transmitting the force 106 of the extraction attack.
- the means 510 for transmitting may comprise two brackets: a first bracket 916 placed at a side of the first support 502 facing away from the slot 500, and a second bracket 942 placed at a side of the second support 504 facing away from the slot 500.
- Each bracket 916, 942 may comprise an interlock mechanism 920, 944
- the lock bit 508 may comprise two counterpart interlock mechanisms 928 (the other interlock mechanism is not visible as it is on the right-hand inner side of the lock bit 508) mating with the interlock mechanisms 920, 944 of the brackets 916, 942.
- the means for transmitting 510 may further comprise a collar 918, 946 in each bracket 916, 942 with a matching collar 938 in each support 502, 504.
- the collar 918, 946 and the matching collar 938 may be positioned and dimensioned in such a manner that the bracket 916, 942 does not slide past the support 502, 504 due to the force 106 of the extraction attack.
- the interlock mechanism 920, 944 of the bracket 916, 942 may comprise grooves and claws, and the counterpart interlock mechanism 928 of the lock bit 508 may comprise counterpart grooves and claws.
- the grooves and claws may interlock with the counterpart grooves and claws when the bracket 916, 942 is rotated in relation to the lock bit 508.
- a basic position of the lock bit 508 in relation to the supports 502, 504 may be adaptable by interlocking the grooves and claws with the counterpart grooves and claws into the basic position.
- the bracket 916, 942 may comprise eight grooves and eight claws, and correspondingly, each counterpart interlock mechanism 928 of the lock bit 508 may comprise eight grooves and eight claws.
- the apparatus may further comprise parts 908, 910, 940, 948, 952 moving in a coaxial direction of the longitudinal axis 960 of a lock cylinder inside the lock bit 508 transmitting a rotational force rotating the lock bit 508 from the side of the first support 502 through the lock bit 508 to the side of the second support 504, so that the lock bit 508 rotation is selected from a side of the lock in an open position, and the rotational force is transmitted to the other side of the lock in order to pull out a key.
- These parts are: a roller 908, a shaft 910, a spring 940, another shaft 948, and another roller 952.
- Each bracket 916, 942 has six radial small holes 962 (the holes of the first bracket 916 are not shown), and one centre hole 964.
- the fingers 914 of the first shaft 910 pass through three holes of the first bracket 916, and also through three holes 962 of the second bracket 942, and, correspondingly, the fingers 950 of the second shaft 958 pass through the remaining three free holes 962 of the second bracket 942, and also through the remaining three free holes of the first bracket 916.
- the spring 940 is in the centre holes 964 of the brackets 916, 942 between the shafts 910, 948. A small coaxial movement, about two millimetres, is thus enabled for the shafts 910, 948 in both directions.
- Each shaft 910, 948 has a groove 912: the idea here is that the actual lock cylinder 600, 604, as illustrated in Figure 6 , has a counterpart ridge mating with the groove and thus transmitting the rotational force.
- a pin 922 and a spring 924 are used to lock the brackets 916, 942 with the lock bit 930.
- Figure 9 illustrates a part of a modular lock cylinder, which, according to the invention, comprises a threaded portion 956, 958, positioned and dimensioned in such a manner that it is screwable together with a matching threaded portion of a lock cylinder 600, 604 as in Figure 6 , or also with the cover part 700 of Figure 7 , or with the knob part 800 of Figure 8 .
- an extension part 602 comprising a threaded portion 954 (the right-hand side of the extension part 602 may also comprise a threaded portion in its inner wall) positioned and dimensioned in such a manner that it is screwable together with the matching threaded portion of the lock cylinder and/or the matching threaded portion of the part of the modular lock cylinder, so that a length of the modular lock cylinder is adaptable along the longitudinal axis 960 of the modular lock cylinder.
- extension parts 602 of various lengths, in steps of five millimetres, for example.
- a matching extension shaft 900 may be needed for the extension part 602.
- One end of the extension shaft 900 has a ridge 904 matching with the groove 912 of the shaft 910.
- the other end of the extension shaft 900 has a groove 902 that is similar to the groove 912 of the shaft 910.
- the apparatus further comprises means 906, 934, 966 for holding the extension part 602 and a part of the modular lock cylinder in alignment with each other after the extension part 602 has been screwed together with the part of the modular lock cylinder.
- the part of the modular lock cylinder is the holder 506.
- the means for holding may be implemented such that the extension part 602 may have a groove 906, and the holder 506 may have a similar groove 934.
- a locking pin 966 may be inserted into the grooves 906, 934 after the extension part 602 has been screwed together with the holder 506 so that these two parts 602, 506 remain in alignment with each other.

Description
- The invention relates to a part of a modular lock cylinder.
- Lock cylinders are tested against various types of attacks. Such tests are described, for example, in European Standard EN 1303 Building hardware - Cylinders for locks - Requirements and test methods, February 2005. In one of its sections, 4.9.4 Resistance to attack by plug / cylinder extraction, it is defined that a lock cylinder of the highest attack resistance grade 2 must be able to withstand a maximum force of 15 kN (= 1500 newtons = 1500 kgm/s2). Another section, 5.9.4 Resistance to attack by plug/cylinder extraction, defines that a self cutting traction screw of a maximum diameter of 5,5 millimetres is to be screwed into the cylinder and an attempt be made to withdraw the cylinder by means of the appropriate maximum force of 15 kN applied progressively without shock within the time (= five minutes) allowed, the time allowance beginning from the commencement of insertion of the traction screw. Now, in order to be able to withstand such an extraction force without breaking, the lock cylinder must have a relatively strong structure. Even a normal one-piece lock cylinder may have problems with achieving the highest attack resistance grade, but the problems are even more serious with modular profile lock cylinders, as specified, for example, in DIN 18252 Profilzylinder für Türschlösser, September 1999.
- The document
EP0874113 discloses a part of a modular lock cylinder according to the preamble of claim 1. Other lock cylinders with measures against attack by plug / cylinder extraction are known fromCH 674543 EP 0676517 . - The present invention seeks to provide an improved part of a modular lock cylinder. According to the present invention, there is provided a part of a modular lock cylinder as specified in claim 1.
- Embodiments of the present invention are described below, by way of example only, with reference to the accompanying drawings, in which
-
Figures 1 and 2 illustrate placement of a lock cylinder and a lock case in a door; -
Figures 3 and 4 illustrate placement of the lock cylinder in relation to the lock case; -
Figure 5 illustrates an apparatus which is part of a modular lock cylinder according to the invention; -
Figures 6, 7, and 8 illustrate various configurations of the lock cylinder; and -
Figure 9 illustrates an exploded view of the apparatus. - The following embodiments are exemplary.
- As illustrated in
Figure 1 , alock cylinder 100 and alock case 104 may be placed in adoor 102. Aforce 106 of an extraction attack is applied along a longitudinal axis of thelock cylinder 100, i.e. on a plane perpendicular to the surface area of thedoor 102. -
Figure 2 illustrates how the parts may be placed in thedoor 102. Thelock case 104 may be pushed into a hollow from a side of thedoor 102, whereupon thelock cylinder 102 may be pushed through ahole 200 in thedoor 102. Ahole 204 in thelock case 104 may accommodate ascrew 202 that is screwed down into ahole 206 of thelock cylinder 100. -
Figures 3 and 4 illustrate the placement of thelock cylinder 100 in relation to thelock case 104. Thelock case 104 is made of two parts: aplate 306 and acase 308. Theplate 306 comprises twoholes lock case 104 is bolted to thedoor 102. Alock bolt 300 is moved 310 in and out within a hole in theplate 306 and by a mechanism accommodated in thecase 308. Amovement 310 of thelock bolt 300 realizes a locking function: if thelock bolt 300 is in the hole in theplate 306, the lock is open, and if thelock bolt 300 protrudes from the hole in theplate 306, the lock is closed. The in and outmovement 310 of thelock bolt 300 takes place along an axis perpendicular to the flat surface of theplate 306. -
Figure 5 illustrates an apparatus which is a part of a modular lock cylinder according to the invention. The apparatus comprises aslot 500 between afirst support 502 and asecond support 504. Thefirst support 502 and thesecond support 504 may belong to aholder 506 forming theslot 500. As illustrated inFigure 5 , theholder 506 may be U-shaped. Thefirst support 502 may be one branch of the U-shapedholder 506, and thesecond support 504 may be the other branch, parallel with thefirst support 502. - The
slot 500 accommodates alock bit 508 movable in theslot 500. The operation of thelock bit 508 will be explained in more detail, but it is a kind of a latch or a cam. Theslot 500 may be implemented by any suitable means for accommodating the lock bit 508: as a suitable aperture, bore, cavity, chamber, groove, hole, hollow, opening, passage, or the like. Thefirst support 502 and thesecond support 504 are to be understood as portions around theslot 500, they 'support' thelock bit 508 at least in the sense that they delimit the movement of thelock bit 508 within theslot 500. - As illustrated in
Figure 5 , thelock bit 508 may be rotatable 514 in theslot 500 between a lock open position and a lock closed position. The lock closed position may be an initial position of thelock bit 508, i.e. 30 degrees in the counterclockwise direction, and the lock open position may be a final position of the lock bit 508 (drawn with a dotted line), i.e. 330 degrees in the counterclockwise direction. - Furthermore, the apparatus comprises means 510 for transmitting a
force 106 of an extraction attack against the apparatus from thefirst support 502 through thelock bit 508 to thesecond support 504. Without themeans 510 for transmitting theforce 106, thefirst support 502 would bend in the direction of theforce 106. Owing to themeans 510 for transmitting theforce 106, however, thefirst support 502, thelock bit 508 and thesecond support 504 appear as if they were one solid piece, making the structure very strong, and thefirst support 502 will not bend. It is worth noticing that if theforce 106 is applied from the opposite direction, the end result is the same: thesecond support 504 will not bend, as the force is transmitted from thesecond support 504 through thelock bit 508 to thefirst support 502. Themeans 510 for transmitting may be implemented as a mechanical coupling or couplings between theparts - The
means 510 for transmitting may also be coupled to thelock case 104. As shown inFigure 1 , the surface area of thecase 308 is relatively large so as to distribute theforce 106 of the extraction attack over a wide area. Thelock case 104 is also coupled to thedoor 102 by screws in theholes lock cylinder 100 is fitted within thelock case 104, torsion forces against thescrew 202 in thehole 206 are small. Consequently, aforce 512 is about the same as theforce 106 of the extraction attack. Theforce 512 is transmitted from themeans 510 for transmitting via thescrew 202 to thelock case 104, so as to keep themeans 510 for transmitting coupled to thelock case 104. - The apparatus of
Figure 5 is a part of amodular lock cylinder 100, such as the one illustrated inFigures 1, 2, 3, and 4 . Thelock cylinder 100 may be an ordinary mechanical lock cylinder. Additionally, or alternatively, thelock cylinder 100 may be a self-powered electromechanical lock cylinder, such as the lock cylinders produced by iLoq, and protected by severalEP applications: 05112272.9 07112677.5 07112676.7 07112673.4 - In the above-mentioned DIN 18252 it is said that: "Der Schliessbart des Profilzylinders bewegt bei Drehung des Schlüssels den Schlossriegel und - bei Vorhandensein eines Wechsels im Schloss - mittelbar auch die Schlossfalle". In the present context, this may be translated as: The
lock bit 508 of theprofile lock cylinder 100 moves the bolt keeper as the key is turned, and consequently, thelock bolt 300 is moved between lock open position and lock closed position. It can be seen inFigure 2 that thelock bit 508 is illustrated therein: thelock bit 508 acts as an interface between thelock cylinder 100 and thelock frame 104. The bolt keeper (not illustrated) is in thecase 308 ofFigure 3 , and it moves thelock bolt 300. -
Figures 6, 7, and 8 illustrate various configurations of thelock cylinder 100. -
Figure 6 illustrates the same configuration of thelock cylinder 100 asFigures 1, 2, 3, and 4 . Thedouble cylinder 100 ofFigure 6 comprises four parts: - a
first cylinder 600 for receiving a key from one side of thedoor 102; - an
extension part 602; - the apparatus of
Figure 5 : theholder 506 with thefirst support 502 and thesecond support 504, and thelock bit 508; and - a
second cylinder 604 for receiving the key from the other side of thedoor 102. -
Figure 7 illustrates a second configuration. WhileFigure 6 illustrates a double cylinder, i.e. a lock cylinder that may be operated with a key from both sides of thedoor 102,Figure 7 illustrates ahalf cylinder 100, i.e. a lock cylinder that may be operated with a key only from one side of thedoor 102. Thehalf cylinder 100 ofFigure 7 comprises the following four parts: - a
cylinder 600 for receiving the key from one side of thedoor 102; - an
extension part 602; - the apparatus of
Figure 5 : theholder 506 with thefirst support 502 and thesecond support 504, and thelock bit 508; and - a
cover part 700. -
Figure 8 illustrates a third configuration, operable from the both sides of thedoor 102 but differing from the configuration ofFigure 6 in that no key is needed for the operation from the other side of thedoor 102. Theknob cylinder 100 ofFigure 8 comprises the following four parts: - a
cylinder 600 for receiving the key from one side of thedoor 102; - an
extension part 602; - the apparatus of
Figure 5 : theholder 506 with thefirst support 502 and thesecond support 504, and thelock bit 508; and - a
knob part 800 with which thelock cylinder 100 may be operated by turning the knob. -
Figure 9 illustrates a further embodiment of the apparatus ofFigure 5 , where the central parts are in the middle: theholder 506 with thefirst support 502 and thesecond support 504, and thelock bit 508 in theslot 500. - The force of the extraction attack against the apparatus comes along a
longitudinal axis 960 of the apparatus, which corresponds with theforce vector 106 illustrated inFigure 1 . The apparatus is also assembled along theaxis 960. - No means 510 for transmitting the force of the extraction attack against the apparatus from the
first support 502 through thelock bit 508 to thesecond support 504 are illustrated with a single reference sign inFigure 9 . -
Figure 9 further shows theU-shaped holder 506.
