CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims priority to U.S. Provisional Patent Application No. 62/142,276, filed Apr. 2, 2015, which is incorporated by reference into the present application. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to the field of lock devices, and more particularly to magnetic lock devices. 
       BACKGROUND 
       [0003]    Usually, cylinder locks require the use of a bitted key adapted to push pins when the key is inserted within the cylinder in order to line the pins up to a shear line and allow the core of the cylinder to rotate freely. Such cylinder locks may be vulnerable to many forms of vandalism, attacks, and/or lock picking, such as the insertion of glue or other contaminants, or the use of lock picking tools to determine when the pins are in an unlocked position. 
         [0004]    In order to overcome the vulnerability of such cylinder locks, a protective device may be used. For example, such a magnetic protective device may comprise a sliding plate to cover the cylinder lock completely and a magnetic key to unlock the protective cover. However, such a protective device requires the user to carry the magnetic key for locking/unlocking the protective device and accessing the cylinder lock in addition to the key for locking/unlocking the cylinder lock. 
         [0005]    Therefore, there is a need for an improved lock system.

       DETAILED DESCRIPTION 
       [0040]      FIG. 1  illustrates one embodiment of a magnetic lock system  10  comprising a magnetic lock device or lock  12  and a magnetic key  14  for locking and unlocking the magnetic lock device  12 . The lock device  12  is securable to an element or object to be locked/unlocked such as a door, a cabinet, or the like. By abutting the magnetic key  14  on the magnetic lock device  12  and rotating the magnetic key  14  according to a respective rotation direction, the magnetic lock device  12  may be locked or unlocked. 
         [0041]      FIG. 2  presents an exploded view of the magnetic lock device  12  which comprises at least a tubular cylinder frame  20 , a cylinder body  22 , a cylinder cap  24 , three magnetic bodies  26 , and a cam  28 . 
         [0042]    The tubular frame  20  extends along a longitudinal axis between a first end  30  and a second end  32  and defines a cylindrical internal cavity  34  which also extends between the first and second ends  30  and  32 . The external longitudinal face  36  that extends between the first and second ends  30  and  32  comprises two threaded sections  38  and  40  spaced apart by two non-threaded sections. The tubular frame  20  further comprises a rim  42  that extends outwardly and radially from the second end  32 . The tubular frame  20  is adapted to be inserted into a hole present in the element to be locked/unlocked, such as a door or a cabinet, until the rim  42  abuts the surface of the element to be locked/unlocked. The two planar sections located between the threaded sections  38  and  40  are used for adequately orienting the tubular frame  20  relative to the element to which it is to be secured. A nut is then screwed on the tubular frame  20  for securing the tubular frame  20  to the element. In one embodiment, the two planar sections may be omitted so that a single threaded section extends around the circumference of the tubular frame  20 . 
         [0043]    As illustrated in  FIG. 3 , the internal wall  44  of the internal cavity  34  of the tubular frame  20  is provided with four recesses  46  which are located at four different angular positions along the perimeter of the wall  44 . In the illustrated embodiment, the recesses  46  are positioned at the following angular positions: 0, 90, 180, and 270 degrees. It should be understood that the illustrated angular positions for the recesses  46  are exemplary only and that other configurations are possible. Similarly and as described below, the number of recesses  46  may vary as long as the internal wall  44  comprises at least one recess  46  defining a locking position for the magnetic lock system  10 . 
         [0044]    The cylinder body  22  comprises a tubular section  50  extending between a first end  52  and a second end  54  along the longitudinal axis. A cylindrical section  56  extends outwardly and longitudinally from the second end  54  of the tubular section  50  and a square hollow section  58  extends outwardly and longitudinally from the first end  52  of the tubular section  50 . The wall or face  60  of the cylindrical section  56  that is opposite to the second end  54  of the tubular section  50  comprises three conical recesses  62 . 
         [0045]    As illustrated in  FIG. 4 , the cylinder body  22  further defines a cylindrical cavity  64  that longitudinally extends through the tubular section  50  and the square section  58  and partially through the cylindrical section  56 . The face  60  further comprises a hole  66  extending therethrough and emerging in the cavity  64 . In the illustrated embodiment, the hole  66  is centered on the face  60  and the conical recesses  62  are positioned at different angular positions about the central hole  66 . 
         [0046]    It should be noted that in the illustrated embodiment the cylindrical section  56  has an external diameter that is less than that of the tubular section  50 . 
         [0047]    As illustrated in  FIG. 5 , the cylinder cap  24  comprises a cylinder section  70  that extends along the longitudinal axis between a first end  72  and a second end  74 . The cylinder section  70  defines a cavity  76  that extends from the first end  72  towards the second end  74 . The cavity  76  comprises a cylindrical cavity section  78  that extends from the first end  72  towards the second end  74  up to a wall  77 , three cylindrical chamber sections  80  that extends from the cylindrical cavity section  78  towards the second end  74 , a central recess section  81  centrally extending from the cylindrical cavity section  78  along a portion of the length of the cylindrical chamber sections  80 , and three conical recesses  82  each extending from a respective cylindrical chamber section  80  towards the second end  74 . The cylindrical cavity section  78  is sized and shaped to receive the cylindrical section  56  of the cylinder body  22  therein. In one embodiment, the diameter of the cylindrical section  56  substantially correspond to that of the cylindrical cavity section  78  so that the cylindrical section  56  be snuggingly received in the cylindrical cavity section  78 . The three cylindrical chamber sections  80  are positioned about the central recess section  81  and they are connected with the central recess section  81  to form a single cavity. 
         [0048]    The cylinder cap  24  further comprises a rim  84  that extends radially and outwardly from the second end  74  of the cylinder section  70 . A key-receiving recess  86  also extends from the second end  74  of the cylinder cap  24  towards the first end  72 . It should be noted that the key-receiving recess  86  is shaped and sized for receiving the magnetic key  14 . 
         [0049]    Referring back to  FIG. 2 , the cylinder lock device  12  further comprises three magnetic bodies  26  which each include a respective cylindrical disk  90  and a respective magnet  92 . Each cylindrical disk  90  extends along the longitudinal axis between a first end  94  and a second end  96  as illustrated in  FIGS. 7 and 8 . A first conical protrusion  98  extends outwardly from the first end  94  and a second conical protrusion  100  extends outwardly from the second end  96 . The first conical protrusion  98  of each cylindrical disk  90  is shaped and sized to be received within a respective conical recess  62  of the tubular section  50 . The second conical protrusion  100  of the each cylindrical disk  90  is shaped and sized to be received within a respective conical recess  82  of the cylinder cap  24 . Furthermore, each cylindrical disk  90  is sized and shaped to be received in a respective cylindrical chamber section  80  of the cylinder cap  24 . 
         [0050]    Each cylindrical disk  90  is further provided with a magnet-receiving hole  102  sized and shaped to receive a respective magnet  92 . In the illustrated embodiment, both the magnet  92  and the magnet-receiving hole  102  have a cylindrical shape. The person skilled in the art will understand that other shapes for the magnet  92  and the magnet-receiving hole  102  are possible as long as the magnet  92  may be received within the magnet-receiving hole  102 . Each cylindrical disk  90  is further provided with a semi-cylindrical recess  104  that extends from the first end towards the second end  96  and from the longitudinal wall  106  of the cylindrical disk  90 . 
         [0051]    Referring back to  FIG. 2 , the cylinder lock device  12  further comprises two active pins  110 . Each active pin  110  is made of a cylinder provided with rounded ends. The longitudinal wall of the tubular section  50  of the cylinder body  22  comprises two holes  112  extending therethrough and each hole  112  is adapted to receive a respective active pin  110 . Each hole  112  is sized and shaped to slidably receive a respective active pin  110  therein. The position of the holes  112  along the length of the tubular section  50  is chosen so that the holes  112  may face a respective recess  46  on the internal wall  44  of the tubular frame  20  when the cylinder body  22  is inserted into the cavity  34  of the cylinder frame  20 . 
         [0052]    The cylinder lock device  12  also comprises a translation pin  120  that includes a cylindrical portion  122  extending along the longitudinal axis between a first end  124  and a second end  126 , and a head section  128  protruding from the second end  126 . The head section  128  has a hemi-spherical shape of which the diameter is greater than that of the cylindrical portion  122 . It should be understood that the head section  128  may be provided with a shape other than a hemi-spherical shape. For example, the head section  122  may be provided with a conical shape, a pyramidal shape, or the like. Similarly, while the present description refers to a pin portion  122  having a cylindrical shape, it should be understood that the portion  122  may have another shape such as a square cross-sectional shape, a rectangular cross-sectional shape, etc. 
         [0053]    The head section  128  is sized and shaped so as to be translationally received within the cavity  64  of the tubular section  50  while the end  124  of the translation pin  120  is sized and shaped to be translationally received within the hole  66  of the cylindrical section  56 . In one embodiment, the curvature of the end  124  is substantially equal to the curvature of the semi-cylindrical recess  104 . 
         [0054]    In one embodiment, a spring  130  is also provided to be positioned about the cylindrical portion  122  of the translation pin  120 . 
         [0055]    When assembling the cylinder lock device  12 , a magnet  92  is inserted into the magnet-receiving hole  102  of each cylindrical disk  90 , thereby forming the magnetic bodies  26 . It should be understood that adhesive may be used to fixedly secure the magnets  92  in their respective magnet-receiving hole  102 . Then the magnetic bodies  26  are each inserted into a respective cylindrical chamber section  80  of the cylinder cap  24  so that the conical protrusion  100  be received into a respective recess  82  of the cylinder cap  24 . 
         [0056]    Then the cylindrical section  56  of the cylinder body  22  is inserted into the cylindrical cavity section  78  of the cylinder cap  24  so that the conical protrusion  98  of each magnetic body  26  be received into a respective conical recesses  62  of the cylindrical section  56 . The cylinder cap  24  is then secured to the cylinder body  22  using a securing pin  140  which is inserted through a hole  142  present in the longitudinal wall of the cylinder section  70  and through a hole  144  present in the external wall of the cylindrical section  56 . While the present description refers to the use of a securing pin  140  for securing together the cylinder cap  24  and the cylinder body  22 , the person skilled in the art will understand that other securing means may be used. For example, a screw may be used. In another embodiment, the holes  142  and  144  may be omitted and an adhesive may be used to secure together the cylinder cap  24  and the cylinder body  22 . 
         [0057]    Once the cylindrical section  56  is inserted into the cylindrical cavity section  78 , the magnetic bodies  26  may each rotate within their respective chamber section  80 . Since the magnets  92  of the magnetic bodies  26  attract one another, the magnetic bodies  26  rotate within their respective chamber section  80  under the attraction force generated between the magnets  92 . The magnetic bodies  26  are then positioned in an inactive position, as illustrated in  FIG. 4 . For at least one given magnetic body  26 , the relative position between the recess  104  and the hole  102  is chosen so that the recess  104  does not face the center of the cylindrical cavity section  78  when the magnetic bodies are in the inactive position. As a result, the end face  94  of the given magnetic body  26  obstructs at least partially the hole  66  present in the face  60  of the cylindrical section  56  when the magnetic bodies  26  are in the inactive position. 
         [0058]    Once the cylinder cap  24  and the cylinder body  22  are secured together, the spring  130  is positioned about the cylindrical portion  122  of the translation pin  120  and the translation pin  120  is inserted into the cavity  64  of the cylinder body  22  so that the end  124  of the translation pin  120  faces the hole  66  of the cylindrical section  56 . The active pins  110  are inserted into their respective hole  112  so that they emerge within the cavity  64  of the cylinder body  22  and that the head section  128  of the translation pin  120  be located between the portion of the active pins emerging within the cavity  64  and the cylindrical section  56 . 
         [0059]    The assembly comprising the cylinder body  22  having the cylinder cap  24  secured thereto, having the active pins  110  inserted into their respective hole  112 , and having the translation pin  120  inserted into the cavity  64  is inserted into the tubular frame  20  until the rim  84  of the cylinder cap  24  abuts against the rim  42  of the tubular frame  20 . The assembly is then rotated until the holes  112  of the tubular section  50  each face a respective recess  46  present on the internal face of the tubular frame  20 . Since it is positioned in compression, the spring  130  exerts a pressure force on the head section  128  of the translation pin  120  which in turn exerts a force on the active pins  110 . As a result of the force exerted by the head section  128 , the active pins  110  each translate within their respective hole  112  and their respective recess  46  until their rounded end abuts the internal wall  44  of the cylinder frame  20  within the recess  46 . The tubular section  50 , and therefore the assembly are then prevented from rotating within the cavity  34  of the cylinder frame  20 . 
         [0060]    The cam  28  is then secured to the square section  58  of the cylinder body  22 . The cam  28  is provided with a square aperture  150  being sized and shaped to snuggingly receive the square section  58 . The square section  58  is then inserted into the square aperture  150  of the cam  28  and a securing means such as bolt  152  is used to fixedly secure the cam  28  to the cylinder body  22  so that a rotation of the cylinder body  22  within the cylinder frame  20  triggers a rotation of the cam  28 . The bolt  152  may be screwed within the cavity  64  of the cylinder body  22 . It should be understood that any adequate method for fixedly securing the cam  28  to the cylinder body  22  may be used. For example, adhesive may be used for fixedly securing the cam  28  to the cylinder body  22 . While the present description refers to a square shape for the section  56  and the aperture  150 , it should be understood that other shapes may be envisioned as long as the section  56  fits into the aperture  150  and a rotation of the section  56  triggers a rotation of the cam  28 . For example, the section  56  and the aperture  150  may each have a triangular shape. 
         [0061]    In one embodiment, a stop plate  154  is inserted between the cam  28  and the cylindrical section  50 . As known in the art, the stop plate  154  is adapted to limit the rotation of the cylinder body  22  to a desired angle such as 90 degrees or 180 degrees. 
         [0062]    As described above, the lock system  10  further comprises a magnetic key  14  which is illustrated in  FIGS. 10-12 . 
         [0063]    The magnetic key  14  comprises three key magnets each corresponding to a respective magnet  92  of a corresponding magnetic body  26 . When the key  14  is positioned within the key-receiving recess  86 , each key magnet attracts its corresponding magnet  92 . The position of each key magnet within the key  14  is chosen as a function of the relative position between the hole  102  and the recess  104  of its respective magnetic body  26  so that, when the key  14  is received within the key-receiving recess  86 , each key magnet attracts its respective magnet  92  and rotates its respective magnetic body  26  up to an active position.  FIG. 13  illustrates the magnetic bodies  26  positioned in the active position when the magnetic key  14  is positioned in the key-receiving recess of the cylinder cap  24 . 
         [0064]    In one embodiment, the key  14  comprises a finger-receiving portion  160  which allows a user to hold the key  14 , and a lock-abutting portion  162  adapted to be inserted into the key-receiving recess  86 . In one embodiment, the lock-abutting  162  comprises a plate  164  insertable into a recess located (not shown) in the finger-receiving portion  160 . The plate  164  comprises three insert-receiving recesses  166  each for receiving a respective insert plate  168 . Each insert plate is provided with a magnet-receiving recess  172  for receiving a respective key magnet  170 . 
         [0065]    The position of the insert-receiving recesses  166  within the plate  164  and the position of the magnet-receiving recesses  172  within the insert-receiving recesses  166  are chosen so that each magnet key  170  attracts its respective magnet  92  and rotates its respective magnetic body  26  up to an active position. 
         [0066]    In one embodiment, the magnetic key  14  and/or the cylinder cap  24  is adapted to adequately orient the key  14  so that each key magnet be adequately positioned relative to its corresponding magnetic body  26  when the key  14  is inserted into the key-receiving recess  86 . For example, the key  14  and the cylinder cap  24  may each be provided with a respective reference mark and the magnetic key is inserted into the key-receiving recess so that the two reference marks face one another. In another example, the magnetic key may be provided with a recess or a notch and the cylinder cap  24  may be provided with a corresponding protrusion adapted to fit into the notch. In this case, the magnetic key  14  is positioned within the key-receiving recess  86  so that the protrusion of the cylinder cap  24  be inserted into the notch of the key  14  in order to adequately position the key magnet relative to their respective magnetic body  26 . In a further example, the magnetic key  24  and the key-receiving recess  86  may be provided with a matching asymmetric shape such as a scalenus triangular shape in order to adequately position the key magnet relative to their respective magnetic body  26  when the magnetic key  14  is inserted into the key-receiving recess  86 . 
         [0067]    Referring back to  FIG. 4 , the magnetic key  14  is away from the key-receiving recess  86  and the magnetic bodies  26  are in the inactive position. When the magnetic bodies  26  are in the inactive position, at least one magnetic body  26  obstructs the aperture  66  of the cylindrical section  56 , thereby preventing the translation pin  120  from entering into the cylindrical cavity section  78 , as illustrated in  FIG. 9 . The compression spring  130  exerts a compression force on the head section  128  of the translation pin  120  which in turn maintains the active pins  110  into their respective recess  46 . The cam  28  is then prevented from any rotation and is in a first position, e.g. the locked position. 
         [0068]    If a user tries to rotate the cylinder cap  24  without inserting the magnetic key  14  within the key-receiving recess  86 , the magnetic bodies which obstruct the aperture  66  prevent the translation pin  120  from entering into the cylindrical cavity section  78 . Since the translation pin  120  cannot translate into the cylindrical cavity section  78 , the head section  128  of the translation pin  120  prevents any translation of active pins  110  towards the center of the cavity  64  and the active pins  110  remain positioned within their respective recess  46 , thereby preventing any rotation of the cylinder body  22  within the cavity  34  of the cylinder frame  20 . 
         [0069]    When the magnetic key  14  is inserted into the key-receiving recess  86 , the key magnets each attract their respective magnet  92 . The magnetic attraction force between the key magnets and their respective magnet  92  triggers a rotation of the respective magnetic bodies  26  and brings the magnetic bodies  26  in the active position. When the magnetic bodies  26  are positioned in the active position, the recesses  104  of the magnetic bodies  26  each face the central recess section  81  and form together with the central recess section  81  a pin-receiving cavity  180  sized and shaped to receive the end  120  of the translation pin  120 , as illustrated in  FIGS. 6 and 13 . 
         [0070]    A rotation of the magnetic key  14  triggers a rotation of the cylinder body  22  relative to the cylinder frame  20  since the cylinder body and the cylinder cap  24  are fixedly secured together. The rotation of the cylinder body  22  relative to the cylinder frame  20  creates a translation force exerted by each recess  46  on its respective active pin  110 . As a result of the translation force, the active pins translate within their respective hole  112  towards the center of the cavity  64  and exert a force on the head section  128  of the translation pin  120 . As a result of the force exerted on the head section  128  by the active pins  110 , the spring  130  is compressed and the translation pin  120  translate towards the cylinder cap  24  so that its end  124  enters the cavity formed by the recesses  104 . The cylinder body  22  may then freely rotate within the cylinder frame  20 . 
         [0071]    In one embodiment, the magnetic key  14  is rotated until each hole  112  faces another recess  46 . When the holes  112  face their respective other recess  46  and the rotation of the magnetic key is stopped, the compression force exerted by the spring  130  on the head section  128  of the translation pin  120  pushes the active pins  110  into their respective other recess  46 , thereby preventing a rotation of the cylinder body  22  within the cylinder frame  20 . The cam  28  is then in a second position, e.g. the unlocked position. 
         [0072]    The cam  28  may be brought back in the first position by rotating the magnetic key in the opposite direction until the holes  112  face the next recess  46  and the spring  130  pushes the active pins  110  in their respective next recess  46 . 
         [0073]    While the present description refers to a frame  20  having a tubular shape, it should be understood the frame  20  may have a shape other than tubular as long as it comprises the cylindrical cavity  34  in which the cylinder body  22  may rotate. 
         [0074]    It should be understood that the number of active pins  110  and the number of holes  112  may vary as long as the magnetic lock device  12  comprises at least one active pin  110  and at least one hole  112 . 
         [0075]    Similarly the number of recess  46  may vary as long as the magnetic lock device  12  comprises at least one recess  46  for each active pin  110 . 
         [0076]    While the active pins  110  have rounded ends, it should be understood the shape of the ends of the active pins may vary. For example, the ends of the active pins  110  may be provided with a conical shape. In another embodiment, they may be flat. 
         [0077]    While they have a hemi-spherical shape, it should be understood that the recesses  46  may be provided with any other adequate shape as long as the walls of the recesses  46  are inclined so as to allow the active pins to slide thereon. 
         [0078]    While the present description refers to the protrusions  100  and  98  for the cylindrical bodies  90  and to corresponding recesses  62  and  82  to allow the rotation of the cylindrical bodies, it should be understood that any adequate rotatable connection may be used. For example, the cylindrical bodies may be rotatably secured to the cylinder body  22  and/or the cylinder cap  24  via a rotation shaft. 
         [0079]    While the present description refers to recesses  104  having the shape of a portion of cylinder, it should be understood that the recesses  104  may be provided with any adequate shape as long as the cavity that they form in connection with the central recess  81  is shaped and sized to receive the translation pin  120 . 
         [0080]    The relative position between the recess  104  and the magnet  92  for each magnetic body  26  and/or the relative position between each key magnet and its respective magnetic body  26  may be varied to create multiple locking combinations. It should be understood that the position of the key magnets  170  within the magnetic key  14  is then chosen as a function of the position of the magnets  92 . It should also be understood that the orientation of the magnets  92  and therefore that of the key magnets  170  may be varied to increase the number of possible locking combinations. It should further be understood that the key magnets  170  have a magnetic force that is adapted to attract their respective magnet  92  and rotate their respective magnetic body  26 . 
         [0081]    The person skilled in the art will understand that the number of magnetic bodies  26  may vary as long as the magnetic lock device  12  comprises at least one magnetic body  26 . Increasing the number of magnetic body  26  allows increasing the number of possible locking combinations. 
         [0082]    In an embodiment in which the magnetic lock device  12  comprises a single magnetic body  26 , the cylinder cap  26  may comprise a reference magnet or a piece of ferrous material for attracting the magnet  92  when the magnetic key  14  is away from the cylinder cap  24  and rotating the magnetic body  26  in the inactive position. 
         [0083]    While the cylindrical bodies  90  are rotatable in the illustrated embodiment, the person skilled in the art will understand that the cylindrical bodies  90  may be slidably secured within the cylinder cap  24 . For example, they may slide along a radial direction to allow movement of the translation pin  120 . In another example, they may slide along the longitudinal axis to allow movement of the translation pin  120 . 
         [0084]    In one embodiment, the cam  28  may be replaced by an electrical conductor element adapted to create an electrical contact between electrical terminals of an electric circuit in order to close the electrical circuit. In this case, the lock is a switch lock. 
         [0085]    It should be understood that the recess  86  may be omitted. For example, the end  74  of the cylinder section  70  may have a knob shape comprising a substantially flat portion for receiving the magnetic key. 
         [0086]    While the present description refers to the cylinder body  22  and the cylinder cap  24  as being separate pieces, the person skilled in the art would understand that the cylinder body  22  and the cylinder cap  24  may be integral together to form a single piece. 
         [0087]    While in the above-illustrated embodiment, the magnetic lock device  12  operates in rotation, the person skilled in the art will understand that the magnetic lock device may operate in translation, i.e. the cylinder body translates with respect to the cylinder frame. In this case, the cylinder cap  24  is pushed or pulled instead of being rotated once the magnetic key  14  has been inserted into the key-receiving recess  86 . 
         [0088]      FIG. 14  illustrates one embodiment of a lock device  200  that operates in translation. The lock device  200  comprises a frame  202 , a lock body  204  which is slidably inserted into the frame  202 , and a lock cap  206 . The lock body  204  is similar to the cylinder body  22  and comprises holes for receiving active pins  110  and a cavity for receiving a translation pin  120 . A locking bolt  208  is secured to the lock body  204  instead of the cam  28 . The lock cap  206  is similar to the cylinder cap  24  and comprises a cavity for rotatably receive three cylindrical disk  90  which are rotatably secured to the lock body  204  and the lock cap  206 . The lock cap  206  comprises a key receiving face  210  on which a magnetic key such as key  14  is abutted for unlocking the lock device  200 . For each active pin  110 , the internal face of the frame  202  comprises a first pin-receiving recess  212  and a second pin-receiving recess  214 . The pin-receiving recesses  212  and  214  are located at the same angular position but at different positions along the length of the internal face of the frame  202 . 
         [0089]    The lock device  200  illustrated at  FIG. 14  is in a first locked position. In this position, the translation pin  120  exerts a pressure force on the active pins  110  which abut in their respective pin-receiving recess  214 , thereby preventing any translation of the lock body  204  within the frame  202 . 
         [0090]    By abutting the magnetic key  14  on the face  210  of the lock cap  206 , the cylindrical bodies  90  rotate and create a cavity adapted to receive the end of the translation pin  120 . When a translation force is exerted on the lock cap  206  while the magnetic key is in physical contact with or is adjacent to the face  210 , the active pins  110  translate towards the center of the lock body  204  and exert a force of the translation pin  120 . As a result of this force, the translation pin  120  translate toward the lock cap  206  and the end of the translation pin  120  enters the cavity created by the alignment of the cylindrical bodies  90 , thereby allowing the active pins  110  to further move toward the center of the lock body  204  and the lock body  204  to move within the frame  202 . During the movement of the lock body  204  within the frame  202 , the spring  130  exerts a force on translation pin  120  which in turn exerts a force on the active pins  110  so that the active pins  110  are in physical contact with the internal wall of the frame  202  and slide thereon. 
         [0091]    When they each face a respective first recess  212 , the active pins  110  enter their respective first recess  212  due to the force exerted by the spring  130  and the translation of the lock body  204  is then stopped. The lock device  200  is then in a second locked position. The translation of the lock body  204  from the first locked position to the second locked position allows moving the locking bolt from a first position to a second position. The locking bolt may be used as a switch for closing an electrical circuit for example. 
         [0092]    It should be understood that the recesses  212  may be omitted. Similarly, one of the recesses  214  and one of the active pins  110  may be omitted 
         [0093]    It should be understood that the above described cylinder lock device may be used as an actuator for different types of locking devices such as a cam lock, a door lock, a gate, a safe cabinet, a locker, or the like. 
         [0094]    In one embodiment, an aim of the present cylinder lock system is to solve the double-layered protection system which requires carrying more keys, and furthermore to provide a solution that eliminates direct contact with the locking mechanism, such that a thief may not feel or listen his way around the locking pins, allowing him/her to achieve the unlocking of the cylinder. 
         [0095]    Another object of the present cylinder lock system is to make picking of the lock extremely difficult even for an expert picker, and resistant to all existing picking methods. 
         [0096]    Another goal is to provide a cylinder lock system that can be applied to common locks of the known type by making the new cylinder of a standard size, while maintaining enough locking combinations for each different application. 
         [0097]    In one embodiment, the present cylinder lock system aims to provide a solution that is structurally simple and has relatively low manufacturing costs in order to make it affordable to end-users. 
         [0098]    The embodiments of the invention described above are intended to be exemplary only. The scope of the invention is therefore intended to be limited solely by the scope of the appended claims.
