Definitions

  • the present invention relates to a cylinder lock of the type described in the precharacterizing portion of claim 1.
  • a cylinder lock of this known type is disclosed in US-A-3 035 433.
  • the known cylinder lock uses springs for moving the locking side bar radially outwardly into the axially extending housing groove to lock the plug against rotation.
  • the object of this invention is to provide an improved cylinder lock which does not require springs for moving the locking side bar between the locking and unlocking positions thereof.
  • a key therein designated 2
  • a shank 4 of rectangular section so that its opposed faces 5 and 6 are flat.
  • Each of the faces is formed with a longitudinally-extended groove, as shown by groove 7 for face 5.
  • Each of these grooves is of a special individual configuration for each key, as will be more particularly described below.
  • One end of key 4 is formed with an enlarged head 8 adapted to be gripped by the user when manipulating the key; and the opposite end is formed with a V-shaped notch 9.
  • the cylinder lock with which key 2 is to be used includes a housing 10 formed with a cylindrical bore receiving a cylindrical plug 12.
  • Plug 12 is in turn formed with a keyway 14 for receiving the key 2 illustrated in Fig. 3 which key, where a proper one, unlocks plug 12 to be rotated within housing 10 along the shear line 16.
  • a rotatable end disc 18 provides protection against drilling.
  • Plug 12 receives an upper group of six pins 20 on one side of the keyway 14, and a lower group of six pins 30 on the opposite side of the keyway.
  • each of the pins 20 (and likewise each of the pins 30) is of T-configuration, including a center leg 21 and a cross-leg 22 at a right-angle to leg 21.
  • the outer face of the cross-leg 22 is formed with a notch 23.
  • the six pins 20 are each disposed within six slots 24 each extending transversely across, and eccentric to, the plug 12.
  • the six slots 24 for the six pins 20 are spaced from each other axially of the plug and are defined by partition walls 25 joined at their inner ends by an inner wall 26 also formed with slots 27 to define ledges for supporting the pins 20 within the slots 24.
  • Plug 12 is further formed with an elongated groove 28 extending axially of the outer face of the plug.
  • Groove 28 is open at the outer surface of the plug, and its lower end is defined by the partition walls 25 of the slots 24 receiving the pins 20.
  • each pin 20 is disposed within its respective slot 24, with the center leg 21 of the pin extending through slot 27 of the supporting ledge 26 into the keyway 14.
  • the center legs 21 projecting into the keyway 14 are of the same width as the specially-configured groove 7 formed in the shank 4 of the key 2.
  • groove 7 of the key cause the center legs 21 of the pins 20 to slide them transversely across the plug 12 to positions according to the shape of the groove.
  • groove 7 is formed in the key shank 4 such that, when a proper key is inserted, all the pins 20 are shifted to locations wherein their notches 23 are aligned to form a straight line underlying the center of groove 28 extending axially of the plug.
  • the other group of pins 30 at the opposite side of the keyway 14 are of the same construction as the pins 20, and are movable within slots corresponding to slots 24 and 27 of pins 20 but formed in the opposite side of the keyway 14. They are thus also positionable by a specially configured groove, corresponding to groove 7 in key 2 but on the opposite face 6 of the key shank 4, such that their notches, corresponding to notches 23 for pins 20, are aligned in a straight line underlying an elongated groove 38 (corresponding to groove 28) extending axially of the plug when a proper key is inserted.
  • the inner face of housing 10 is formed with axially-extending grooves 40 and 42 on opposite sides of keyway 14 in alignment with grooves 28 and 38, respectively, and with the line of notches 23 of the two groups of pins 20 and 30 when shifted by the proper key.
  • Elongated locking pins, 44 and 46, respectively, are disposed within these elongated grooves 28 and 38.
  • Pin 44 is illustrated in Figs. 7 and 8, and pin 44 is of identical configuration.
  • locking pin 44 is of equal length to the axial length of grooves 28 and 40 formed, respectively, in the plug and in the inner face of housing 10.
  • the upper and lower edges of locking pin 44 are each of V-shape, corresponding to the V-shape of elongated groove 40 in housing 10 and of the notches 23 in the pins 20.
  • the width of locking pin 44 is such that whenever its lower edge 48 engages an unnotched surface of one of the pins 20 its opposite edge 47 projects into the elongated groove 40 formed in the inner face of the housing 10, thereby preventing the rotation of plug 12 within the housing; but when the pins 20 are aligned so that their notches 23 form a straight line, the lower edge 48 of the elongated pin seats within the straight line of notches whereby the upper edge 47 of the pin withdraws from the elongated groove 40 of the housing. That is to say, when notches 23 are aligned, locking pin 44 does not project past the shear line 16 between plug 12 and housing 10, thereby permitting the plug to rotate within the housing.
  • the lower elongated locking pin 46 cooperates with the lower set of pins 30 and housing groove 42 in the same manner.
  • pins 20 (and also the pins 30) are formed with their cross-legs 22 of square section, as shown in Figs. 5 and 6, it will be appreciated that such legs may be of other section, e.g. cylindrical section as shown at 22a in Fig. 6a.
  • outer edges 47 and 48 of the elongated locking pins 44 and 46 are of V-shape as shown in Figs. 7 and 8, it will be appreciated that they could also be of rounded shape as shown by edges 47a, 48a of pin 44a in Fig. 8a.
  • the elongated grooves 40 and 42 formed in the innerface of housing 10, and the notches 23 formed in the pins 20 and 30, would be of complementary rounded shape.
  • the lock could include only one group of pins, e.g., group 20, movable by one elongated slot (corresponding to slot 7) formed in the key 2, or two groups cooperable with two key slots on opposite sides of the key but of different configurations.
  • Figs. 9-12 illustrate a still further variation, wherein the invention is embodied in a hybrid lock, namely one in which one-half includes the above-described construction, and the other half includes the construction of a conventional pin- tumbler type lock.
  • a hybrid-type key such as illustrated in Figs. 10-12, therein designated 102.
  • key 102 includes one face 105 (Fig. 11) formed with a specially-configured longitudinally-extending groove 107, corresponding to groove 7 in Fig. 3; and the other face 106 (Fig.
  • the lock itself as shown in Fig. 9, includes a housing 110 receiving a cylindrical plug 112 formed with a keyway 114 adapted to receive a key which, if the proper one, will permit the plug to be rotated within the housing along shear line 116.
  • the upper half of plug 112 carries a plurality of pins 120 each of the same structure and formed with the same notch 123, as pins 20 in the previously-described embodiment, which notches 123 are cooperable with an elongated locking pin 144, corresponding to pin 44 in the above-described embodiment.
  • the lower half of plug 112 is formed with conventional pin tumblers, therein designated 150, each constituted of two segments 151, 152, urged by a spring 153 such that, normally, segments 152 projects within the shear line 116 between the plug 112 and the housing 110, thereby blocking the rotation of the plug within the housing.
  • both groups of pins namely the slidable pins 120 acting on the elongated locking pin 144 and the pin tumblers 150, block the rotation of the plug 112 within the housing 110.
  • groove 107 formed on one face 105 of the key moves the upper pins 120 to align their notches 123 such as to receive the elongated locking pin 144 and to permit it to be retracted to the shear line 116 between plug 112 and housing 110; and the blind bores 109 formed on the opposite face 106 of the key move the pin tumblers 150 such as to bring the abutting surfaces between their two segments 151, 152 to the shear line 116.
  • the plug 112 is thus free to rotate within the housing 110.
