Definitions

  • the present invention relates to a key, and more particularly, to a key having recesses of different depths and magnetic members are arranged in some of the recesses to prevent the key from being copied.
  • a conventional lock generally includes a core with beads and the key includes recesses of different depths so as to accommodate the beads to correctly rotate the core of the lock.
  • the beads are equipped with outer parts and inner parts which are movably located in the outer parts to form different combinations of the beads, such that the core cannot be easily copied.
  • the conventional lock can be unlocked by using L-shaped tool or universal, key to shift the beads to correct positions.
  • L-shaped tool or the like can be inserted into the gap and move the beads to unlock the lock. Therefore, the conventional locks with the beads are not safe as expected.
  • the key for the conventional locks includes recesses which are located corresponding to the beads, the arrangement of the recesses cannot change and the combination of the allocations of the recesses is limited. When the combination of allocations of the recesses are utilized, new models are needed to be developed and which takes time and cost. The conventional keys need to be improved.
  • the present invention intends to provide a key which has multiple different arrangement options for the recesses, grooves, and magnetic so as to improve the shortcomings of the conventional keys.
  • the present invention relates to a key and comprises a shank having at least one recess. At least one magnetic member is received in the at least one recess and a number of the at least one magnetic member is not more than a number of the at least one recess.
  • the at least one recess having no the at least one magnetic member received therein includes an engaging portion.
  • the engaging portion has concavities of different depths.
  • the engaging portion has convexes of different heights.
  • the at least one recess is arranged unevenly spaced apart.
  • the at least one recess includes different depths.
  • the shank has at least one groove and the at least one groove has different lengths.
  • the primary object of the present invention is to provide a key which involves different combinations for arranging the positions of the grooves, the recesses and the magnetic members so as to prevent from being copied.
  • the key of the present invention comprises a shank 1 having at least one groove 12 and at least one recess 11.
  • the at least one groove 12 has different lengths.
  • the at least one recess 11 is arranged unevenly spaced apart and/or has different depths.
  • At least one magnetic member 2 is received in the at least one recess 11 and a number of the at least one magnetic member 2 is not more than a number of the at least one recess 11.
  • the at least one recess 11 having no the at least one magnetic member 2 received therein includes an engaging portion 111.
  • the engaging portion 111 has concavities of different depths and/or the engaging portion 111 has convexes of different heights.
  • a lock is for the key of the present invention, and the lock includes a case 3 in which a core 4 is received.
  • the core 4 has a keyhole 41 so that the shank 1 of the key of the present invention can be inserted therein.
  • the shank 1 may have or may not have the grooves 12.
  • the holes 5 receive one of the bead units 6a, 6b, 6c.
  • the bead unit 6a includes a cover 61 and two springs 62 are located on two opposite sides of the cover 61.
  • the spring 62 that is located on outside of the cover 61 is connected with a main bead 63 which has a sub-bead 64 received therein.
  • the spring 62 that is located on the inside of the cover 61 is located corresponding to the sub-bead 64.
  • a down bead 65 is located between the main bead 63 and the inside of the keyhole 41 and is in contact with the main bead 63.
  • the recesses 11 have different positions, depths or shapes, so that the end of the down bead 65 of the bead unit 6a that is in contact with the inside of the keyhole 41 is located corresponding to the recess 11 that does not have the magnetic member 21 received therein.
  • the down bead 65 has a down sub-bead 66 which is located corresponding to the sub-bead 64.
  • the down sub-bead 66 is in contact with the sub-bead 64,
  • the down sub-bead 66 has an end contacting the inside of the keyhole 41.
  • the bead unit 6b includes a cover 61 which is connected to a spring 62 and a bead 67 from an end of the case 3.
  • the bead 67 has a room 671.
  • a down bead 65 is located between the bead 67 and the inside of the keyhole 41.
  • the down bead 65 has a magnetic bead 68 at the center thereof and the magnetic bead 68 is located corresponding to the room 671.
  • the magnetic bead 68 is magnetically attracted to the magnetic member 2.
  • a spring 681 is located between the inside of the keyhole 41 and the magnetic bead 68, so that when the magnetic bead 68 is not attracted by the magnetic member 2, the magnetic bead 68 is pushed by the spring 681 and contacts the inside of the room 671.
  • the magnetic bead 68 is located between the case 3 and the core 4 which is then not rotatable.
  • the magnetic bead 68 When the shank 1 is inserted into the keyhole 41, the magnetic bead 68 is attracted by the magnetic member 2 to compress the spring 681, such that the magnetic bead 68 is disengaged from the room 671.
  • the contact surfaces of the down bead 65 and the bead 67 are located on the same plane with the surfaces between the case 3 and the core 4.
  • the magnetic bead 68 does not block the plane so that the case 3, the core 4 and the bead unit 6b are not interfered.
  • the bead unit 6c includes a cover 61 which is connected to a spring 62 and a bead 67 from an end of the case 3.
  • a down bead 69 is located between the bead 67 and the inside of the keyhole 41.
  • a room 671 is located between the bead 67 and the down bead 69.
  • a magnetic bead 68 is located in the room 671. The magnetic bead 68 and the magnetic member 2 are magnetically repulsed to each other.
  • a spring 681 is located between the bead 67 and the magnetic bead 68, so that when the magnetic bead 68 is not repulsed by the magnetic member 2, the magnetic bead 68 is pushed by the spring 681 and contacts the down bead 69.
  • the magnetic bead 68 is located between the case 3 and the core 4 which is then not rotatable.
  • the magnetic bead 68 is repulsed by the magnetic member 2 to compress the spring 681, such that the magnetic bead 68 is disengaged from the room 671.
  • the contact surfaces of the down bead 69 and the bead 67 are located on the same plane with the surfaces between the case 3 and the core 4.
  • the magnetic bead 68 does not block the plane so that the case 3, the core 4 and the bead unit 6c are not interfered.
  • the bead units 6a, 6b, 6c, the case 3 and the core 4 are not interfered, so that the core 4 can be rotated to unlock the lock.
  • Fig. 8 shows the second embodiment and the difference compared to the first embodiment is that the shank 1 of the key does not have any groove 12 so that there is plenty of room for the recesses 11 and the magnetic members 2.
  • the arrangements of the magnetic poles between the magnetic members 2 have more options.
