Definitions

  • This invention relates to improvements in rotating pin tumbler side bar locks and keys therefor.
  • Security is a necessary feature of a lock and additional security that could be applied to twisting tumbler locks with dual mechanisms would be highly desirable.
  • a further and extremely desirable feature of a high security lock is the capability for master keying. Providing additional security and utilizing such provision for master keying provides capability for master keyed systems. It is also advantageous to have a unique key and key blank for locks of the type in order to provide the additional security that key control can accomplish.
  • This invention relates to improvements to enhance the security of the basic twisting tumbler dual locking mechanism lock known as the Medeco type lock and can be applied to any Medeco type lock with a side bar mechanism including the original Medeco cylinder lock, the Medeco cam lock, the Medeco Biaxial® lock, and the Medeco Bi-Level® lock with offset tip tumbler pins.
  • the invention utilizes a sliding member which slides generally axially in the cylinder of the lock and has a projection for contact with an end of a rib on a key blade. The key thus positions the slider which controls the side bar to allow the side bar to move to an unblocked position.
  • the slider control of the side bar and the unique key and key blade provide further degrees of security, allow master keying and key control .
  • FIG. 1 is a end elevation view of the cylinder or plug of a twisting tumbler lock having a side bar;
  • FIG. 2 is a longitudinal section view taken along line 2- 2 of FIG. 1;
  • FIG. 3 is a horizontal section view taken along line 3-3 of FIG. 2;
  • FIG. 4 is a plan view of a key blank of this invention
  • FIG. 5 is an end elevation view similar to FIG. 1 with the lock in unblocked position
  • FIG. ⁇ is a longitudinal sectional view taken along lines 6-6 of FIG. 5;
  • FIG. 7 is a longitudinal sectional view taken along lines 7-7 of FIG. 6;
  • FIGS. 8, 9, 10 and 11 are alternative embodiments showing a cut key of this invention with the slider superposed thereon to illustrate the possibilities of master keying.
  • FIG. 12 is a sectional elevation view of the prior art, Medeco cylinder lock, to show the setting of this invention.
  • FIG. 13 is a sectional view taken along line 13-13 of FIG. 12.
  • FIG. 14 is an end elevational view of the cylinder of a twisting tumbler lock having a side bar and showing a further embodiment of embodiment of this invention.
  • FIG. 15 is a longitudinal sectional view taken along line 15-15 of FIG. 14.
  • FIG. 16 is a horizontal view taken along line 16-16 of FIG. 15.
  • FIG. 17 is an end elevational view of the cylinder shown in FIG. 14 showing the components of ' the cylinder in their locked position.
  • FIG. 18 is a longitudinal section view taken along line 18-18 of FIG. 17.
  • FIG. 19 is a horizontal sectional view taken along line 19-19 of FIG. 18.
  • FIG. 20 is a plan view of a key blank for key of this invention.
  • a cylinder or plug 10 has a keyway 12 as is conventional in Medeco locks.
  • Tumbler holes 14 are provided for rotating, reciprocating, i.e., twisting tumblers 11 (FIG. 12) which have configurations 13 on their side for reception of a side bar 16 as taught and shown in the prior art Medeco constructions and patents identified above, see FIGS. 12 and 13. Because remaining portions of such Medeco locks are known, for the sake of simplicity they have not been shown, except for the illustration of prior art in FIGS. 12 and 13.
  • the side bar 16 is positioned to reciprocate transverse to the axis of the cylinder plug 10 and biased by springs away from the plug to provide a further level of locking control for the lock, as is known.
  • the side bar has a cam 18 for cooperating with a cam groove 19 on the inside of the casing, also as is conventional in Medeco locks, see FIG. 13. When the plug is attempted to be rotated by the key the cam groove 19 allows the side bar to be forced inwardly toward the center of the cylinder.
  • the side bar has projections 20 for engaging the configurations 13 on the tumblers 11 to allow the side bar to move toward the axis of the plug and clear the casing when the tumblers are rotated by the key to a correct position, as in known Medeco locks.
  • the side bar also has spaced slots 22 positioned along its lower surface as shown in FIGS. 1 and 2. Projections 23 are defined by the spaces between the slots .
  • a slider 24 Positioned in an axial hole 30 in the cylinder plug is a slider 24 which can slide on an axis parallel to the axis of the rotatable cylinder plug.
  • the slider itself has a projection 26 at one end which extends into the keyway 12 for engagement with proper key as will be described.
  • a spring 28 is provided for biasing the slider axially in hole 30 in a duration toward the front or key entry point of the lock.
  • the slider 24 also has spaced tangs 32 on its surface as shown in FIGS. 1, 2 and 3. These tangs are of sufficient size and length to either fit in the slots 22 of the side bar when the slider is properly positioned, or interfere with the projections 23 on the side bar when not properly positioned. As shown in FIG. 2, the tangs 32 on the slider and projections 23 on the side bar 16 interact thus preventing the side bar from moving inwardly, thus blocking operation of the side bar and hence the lock.
  • the slider provides a third level of lock control in addition to the reciprocation and rotation of the tumblers.
  • a unique key blank 34 may be provided with proper bitting 35 for operating the lock.
  • the key blank has a bow 36 and a blade 38.
  • the blade has a profile which conforms to the profile of the keyway 12.
  • FIGS. 8, 9, 10 and 11 show other embodiments having different configurations of the contact surface 42 on key rib 40 and showing the slider 24 superimposed, the slider projection 26 having a surface complimentary to the contact surface 42.
  • FIG. 8 is the same as the FIGS.
  • FIG. 9 the slider projection as a step 44 for receiving a similarly configured key rib end 42a.
  • FIG. 10 has a slanting surface 46 for cooperating with a slant surface 42b on the distal end of key rib 40.
  • FIG. 11 has a tooth shaped surface 48 on projection 26 for cooperating with a complimentary shaped rib surface 42.
  • the key of FIG. 8 will correctly position the slider shown in FIG. 8 and the key of FIG. 11 will correctly operate the slider in FIG. 11.
  • the key in FIG. 8 will also correctly position the slider of FIG. 11.
  • the key of FIG. 11 will push the slider of FIG. 8 too far and the lock will not open.
  • FIGS. 14-20 show an alternative embodiment in which the blocking member or slider instead of being a rod insertable into the end of the cylinder is in the form of a block which is insertable from the bottom of the keyway.
  • the blocking member or slider instead of being a rod insertable into the end of the cylinder is in the form of a block which is insertable from the bottom of the keyway.
  • FIGS. 14, 15 and 16 show the slider in position to not block the side bar.
  • the plug 10 has its keyway 12 open at the bottom.
  • the side bar 16' has spaced slots 22' which will allow the sidebar to either clear or be blocked by the slider as will be described below.
  • the invention is in the environment of the Medeco twisting tumbler locks as shown in FIGS.
  • the slider in this embodiment is a block shaped member 24' shaped to fit within the cylinder shell and to be inserted from the open bottom of the keyway 12.
  • a spring 28' is provided by biasing the slider toward the bow of the key as shown in FIGS. 15 and 18. '
  • the slider moves axially of the key in space 30'.
  • the plug shaped slider has spaced tangs 32' on its upper surface as shown in FIGS. 15 and 18. These tangs can move into slots 22 in the side bar when the slider is positioned by the key as shown in FIGS. 15 and 16. However, as shown in FIG.
  • the key 34' is inserted into the keyway 12 to move the slider 24' against the bias of spring 28' and when the projections 32' are in the position to cooperate with grooves 22', the side bar 16' can operate to allow the key to turn the plug and operate the lock. Unless the portion 42' of the key 34' contacts the projection of 35, the slider or block 24' will block operation of the lock.
  • FIGS. 8-11 could also be used with this embodiment .
  • the advantage of this construction is that it allows master keying and provides further security because it does not require the conventional pin and tumbler master keying techniques to be used to configure the locks with the selective master keying capability. When used to supplement conventional master keying techniques, it provides additional capability thus offering the customer the most secure system.
