Definitions

  • the present invention relates to locks generally, and particularly to locks wherein turning of a key controls passage of a locking bolt through the lock.
  • Various types of locks are known in the art that operate with a key which turns a tumbler to control passage of a locking bolt through the lock.
  • a key which turns a tumbler to control passage of a locking bolt through the lock.
  • a padlock there is generally a tongue that lockingly engage a locking bolt. Turning a key releases the tongue and allows moving or completely removing the locking bolt.
  • the key rotates a lock cylinder having a tumbler with spring loaded pins, as is well known in the art.
  • these types of locks are meant to safeguard belongings, such as a vehicle, wherein the locking bolt denies access or entry to such belongings, such as preventing movement of a gear shift lever, for example.
  • a problem associated with such locks is that after removing the locking bolt, the key can be removed from the lock. This means that a negligent person can walk away from the lock with key in hand, and yet the locking bolt is not in its proper place, i.e., in locking engagement inside the lock and protecting the belongings.
  • Austrian Patent 31 08 606 describes a padlock with a lock housing and an essentially U-shaped shackle movable therein having two arms of different lengths. When the shackle is opened, the longer leg remains in the padlock body to operate a mechanism that blocks removal of the key. However, in this padlock, the operation of the blocking mechanism requires that the shackle at least partially remain in the lock housing, and so the device is not applicable for locks wherein it is desired to completely remove the shackle from the lock.
  • German Patent 1,939,011 also describes a padlock with a mechanism for blocking removal of the key from the lock housing.
  • this mechanism is also limited to a lock wherein the shackle is not completely removable from the lock housing.
  • Israel Patent 102153 issued to Applicant, describes a padlock with a locking mechanism actuated by a key-operated cylinder.
  • the lock housing has a pair of bores for receiving therein a pair of legs of a shackle.
  • the key can be removed from the cylinder only in a first orientation wherein the locking mechanism extends into the shackle receiving bores.
  • the shackle is completely removable from the lock housing.
  • the padlock requires a pair of blocking elements to prevent the locking mechanism from being in the first orientation except when the shackle is locked in the shackle receiving bores. It is also an essential feature of the device that the lock mechanism be actuated by rotation of the cylinder.
  • the present invention seeks to provide an improved lock wherein the key cannot be removed therefrom unless the locking bolt is properly lockingly engaged in the lock.
  • the locking mechanism that prevents removal of the key is not operated by rotation of a key-operated tumbler, but rather selectively engages the locking pin and the tumbler and prevents rotation of the tumbler if the locking bolt is not in place.
  • the tumbler is prevented from rotating at an angular orientation that precludes removal of the key therefrom.
  • the present invention does not require blocking elements to negate the action of the locking mechanism when the locking bolt is in place.
  • the lock of the present invention is particularly useful for locks equipped with a single locking bolt, although it may be adapted for padlocks with double leg shackles as well.
  • lock apparatus including a lock body having a first elongate bore extending along a first longitudinal axis and a second elongate bore extending along a second longitudinal axis, a tumbler disposed within the first elongate bore and arranged for rotation about the first longitudinal axis, the tumbler being formed with a hole, a locking bolt disposed in the second elongate bore and arranged for sliding motion substantially along the second longitudinal axis into an unlocked orientation, and a tumbler rotation preventer biased against a surface in the lock body and lockingly engageable with the tumbler, the tumbler rotation preventer including a protruding member, such that in the unlocked orientation the protruding member is lockingly engaged with the hole.
  • a portion of the locking bolt is biased against the tumbler rotation preventer, thereby moving the tumbler rotation preventer out of locking engagement with the tumbler.
  • the tumbler is rotatable by means of a key inserted therein, and the key cannot be removed from the tumbler when the tumbler rotation preventer is lockingly engaged with the tumbler.
  • lock apparatus also includes a plurality of body pin assemblies disposed in a plurality of body pin bores located within the lock body and communicating with the first elongate bore, a plurality of tumbler pin assemblies disposed in a plurality of tumbler pin bores located within the tumbler and communi- eating with the first elongate bore, the plurality of tumbler pin assemblies being arranged such that upon suitable rotation of the tumbler in the first elongate bore, each of the tumbler pin assemblies is aligned coaxially with a corresponding one of the body pin assemblies, the key being removable from the tumbler only when each of the tumbler pin assemblies is aligned coaxially with a corresponding one of the body pin assemblies, and the tumbler rotation preventer lockingly engages the tumbler at a rotational orientation thereof such that each of the tumbler pin assemblies is not aligned coaxially with a corresponding one of the body pin assemblies.
  • the tumbler rotation preventer includes an end adapted to be biased against a portion of the locking bolt, the end being co plementarily shaped to fit a shape of the portion of the locking bolt.
  • Fig. 1 is a simplified pictorial, partially cutaway, partially exploded illustration of lock apparatus constructed and operative in accordance with a preferred embodiment of the present invention
  • Figs. 2 and 3 are simplified, partially sectional, front view illustrations of a portion of lock apparatus of Fig. 1, respectively before and after engagement of a protruding member of a tumbler rotation preventer with a hole formed in a tumbler;
  • Fig. 4 is a partially exploded, partially sectional, top view illustration of lock apparatus of Fig. 1, with a locking bolt in an unlocked orientation relative to a lock body, and a key retained inside the lock body;
  • Fig. 5 is a partially sectional, top view illustration of lock apparatus of Fig. 1, with the locking bolt partially inserted into the lock body, and the key retained inside the lock body;
  • Fig. 6 is a partially exploded, partially sectional, top view illustration of lock apparatus of Fig. 1, with the locking bolt in a fully locked orientation and the key removed from the lock body.
  • FIG. 1 illustrates lock apparatus 10 constructed and operative in accordance with a preferred embodiment of the present invention. It is noted that Fig. 1 is a simplified illustration that shows only those elements of lock apparatus 10 which are essential for understanding the present invention.
  • Lock apparatus 10 preferably includes a lock body 12 having a first elongate bore 14 extending along a first longitudinal axis 16 and a second elongate bore 18 extending along a second longitudinal axis 20.
  • a tumbler 22 is preferably disposed within first elongate bore 14 and is arranged for rotation about first longitudinal axis 16. Tumbler 22 preferably has a keyway 24 formed therein for inserting therein a key 26.
  • a locking bolt 28, preferably made of a hardened steel, may be disposed in second elongate bore 18.
  • Locking bolt 28 preferably includes a generally cylindrical shank 30 with a tapered end 32.
  • a notch 34 is preferably formed in shank 30 at a location between tapered end 32 and a head portion 36.
  • a biasing element, such as a spring 38, is preferably disposed on shank 30 adjacent head portion 36.
  • Locking bolt 28 is preferably arranged for sliding motion substantially along second longitudinal axis 20.
  • Lock apparatus 10 preferably includes a tumbler rotation preventer 40 which may be biased against a surface 42 in lock body 12 by means of a biasing device, such as a spring 44.
  • tumbler rotation preventer 40 is preferably constructed of a bent or formed hardened metal strip that includes a protruding member 46 which is lockingly engageable with a hole 48 formed in tumbler 22.
  • Tumbler rotation preventer 40 also preferably includes an end 50 adapted to be biased against a portion of locking bolt 28. As seen in Fig. 1, end 50 is preferably complementarily shaped to fit the contour of the outer periphery of locking bolt 28.
  • FIG. 1 illustrates lock apparatus 10 in a simplified exploded view, and protruding member 46 and hole 48 are not shown in an operative orientation. The alignment of protruding member 46 with hole 48 is illustrated and described with reference to Figs. 2 and 3.
  • lock apparatus 10 preferably includes a plurality of body pin assemblies 52 disposed in a plurality of body pin bores 54 located within lock body 12 and which communicate with first elongate bore 14.
  • a plurality of tumbler pin assemblies 56 are preferably disposed in a plurality of tumbler pin bores 58 located within tumbler 22 and communicate with first elongate bore 14.
  • Tumbler pin assemblies 56 are preferably arranged such that upon suitable rotation of tumbler 22 in first elongate bore 14, each tumbler pin assembly 56 is aligned coaxially with a corresponding body pin assembly 52.
  • Key 26 is removable from keyway 24 of tumbler 22 only when each tumbler pin assembly 56 is aligned coaxially with a corresponding body pin assembly 52, at which alignment each tumbler pin assembly 56 is free to extend into a corresponding body pin bore 54 and push against a corresponding body pin assembly 52, thereby allowing removal of key 26.
  • each tumbler pin assembly 56 is aligned coaxially with a corresponding body pin assembly 52 and key 26 may be removed from tumbler 22.
  • Hole 48 is angularly offset from the horizontal by an angle 60.
  • Fig. 4 illustrates locking bolt 28 in an unlocked orientation relative to lock body 12.
  • Spring 44 is extended so that tumbler rotation preventer 40 is engaged with hole 48 of tumbler 22 and key 26 is retained inside lock body 12.
  • the orientation of Fig. 4, which corresponds to that shown in Fig. 3, is an unlocked orientation.
  • An unlocked orientation may be attained by completely removing locking bolt 28 from lock body 12, as shown in Fig. 4.
  • an unlocked orientation may be attained with locking bolt 28 partially inserted into lock body 12, as long as tapered end 32 does not sufficiently push tumbler rotation preventer 40 in the direction of an arrow 66, so as to dislodge protruding member 46 from hole 48.
  • Locking apparatus 10 preferably includes a locking tongue 70 which is arranged for selectable locking engagement with locking bolt 28. Locking tongue 70 is actuated by rotation of tumbler 22, as is well known in the art. In the orientation of Fig. 5, locking tongue 70 contacts shank 30 and key 26 cannot be removed from lock body 12.
  • Fig. 6 illustrates locking bolt 28 fully inserted into lock body 12. It is seen that locking tongue 70 now contacts shank 30 at notch 34. At this position, locking tongue 70 does not prevent rotation of tumbler 22. Since protruding member 46 does not engage hole 48, key 26 may now be removed from tumbler 22, as seen in Fig. 6.
