Definitions

  • the invention relates to a lock apparatus, more particularly to a weather-resistant lock apparatus that is suitable for use in dusty and wet environments.
  • a padlock body in current padlock structures, includes a padlock housing and a U-shaped shackle, and a lock core device is mounted in the padlock housing.
  • the lock core device is operable to engage and disengage the shackle so as to enable locking and unlocking operations in a conventional manner.
  • the lock core device is provided with a keyhole for receiving a key, if the padlock is used outdoors and is exposed to influences of natural forces, such as rain and wind, the service life of the padlock will be shortened.
  • the padlock is used in a windy and sandy environment, tiny grains of sand and grit may gain entry into the interior of the lock core device through the keyhole and cause jamming of the internal components of the lock core device, thereby rendering the padlock inoperable.
  • the padlock is used in a wet and humid environment, moisture may seep into the interior of the padlock housing through available clearances and gaps so that, after a period of time, components within the padlock housing will become rusty.
  • any moisture that gets into the interior of the padlock may lead to freezing of the internal components, thereby rendering the padlock inoperable.
  • padlock may be provided with a protective shroud to help maintain the operability of the padlock in harsh and extreme environments, in order to meet government regulations, such as those set by the U.S. Department of Defense, padlocks should not have an external protective shroud and should be resistant to dirt, moisture, corrosion, freezing, etc., by virtue of their inherent construction. Therefore, as to how padlocks can be constructed to endure extreme environments without having a protective shroud is the object of endeavor of manufacturers in the industry.
  • the object of the present invention is to provide a weather-resistant lock apparatus suitable for use in dusty and wet environments.
  • a weather-resistant lock apparatus comprises a lock core device that includes a lock shell and a lock core unit.
  • the lock core unit includes an inner shell received in and rotatable relative to the lock shell, a plurality of locking plates received in and rotatable relative to the inner shell and cooperating to form a keyhole of the lock core unit, a locking unit operably associated with the locking plates for locking the inner shell against rotation relative to the lock shell in a locking state of the locking plates, and for unlocking the inner shell for rotation relative to the lock shell in an unlocking state of the locking plates, a latch actuator coupled to the inner shell, and a plurality of spacer plates, each of which is disposed between an adjacent pair of the locking plates.
  • the spacer plates are made of a material with a hardness less than that of the locking plates.
  • the lock core unit further includes a drive plate received in and rotatable relative to the inner shell.
  • the drive plate is disposed between the locking plates and the latch actuator, and cooperates with the locking plates to form the keyhole.
  • the drive plate is capable of transmitting a rotary force applied through a correct key that was inserted into the keyhole to the latch actuator.
  • the drive plate is formed with a non-circular drive hole that forms a part of the keyhole.
  • the lock core unit further includes a rotation control member mounted on the latch actuator and registered with the drive hole. The rotation control member extends into and engages the drive plate in the drive hole to prohibit rotation of the drive plate, and is movable to disengage from the drive plate when the correct key is inserted into the keyhole so as to permit rotation of the drive plate with the correct key in order to drive rotation of the latch actuator.
  • the lock apparatus further comprises a padlock body that includes a padlock housing and a shackle member.
  • the padlock housing is formed with a core chamber, and has a bottom portion formed with an opening for access into the core chamber.
  • the lock core device is received in the core chamber.
  • the padlock housing further has a top portion formed with two shackle holes.
  • the shackle member has two insert ends that are inserted into the shackle holes, respectively.
  • the padlock body further includes a latch unit disposed in the padlock housing and coupled to the latch actuator for engaging at least one of the insert ends of the shackle member.
  • the padlock body further includes two seal rings, each of which is retained in a respective one of the shackle holes for establishing airtight contact with a respective one of the insert ends of the shackle member.
  • the weather-resistant lock apparatus is shown to be embodied in a padlock that includes a lock core device 10, a padlock body 20 (see Figures 3 and 4), and a key 30 that can work on the lock core device 10 for locking and unlocking purposes.

  • the longer insert end 231 of the shackle member 23 shields the threaded rod 252 of the securing member 25, loosening of the threaded rod 252 is not permitted at this time such that removal of the lock core device 10 is not possible.
  • the drive plate 13 of the lock core device 10 is prevented from rotation by the control pin 193 of the rotation control member 19.
  • the rotation control member 19 is provided mainly to maintain the drive plate 13 in a non-rotatable state. Therefore, even if the lock apparatus of this invention is subjected to strong external impact, the drive plate 13 will not be shaken out of place, and the locked state of the lock core device 10 can be maintained.
  • the correct key 30 has to be inserted into the keyhole of the lock core device 10.
  • the key bit portions 32 of the key 30 are used to bring the locking plates 14 to an unlocking state where the notches 141 in the locking plates 14 are aligned with one another so that the first control rod 123 can extend into the notches 141 in the locking plates 14 and disengage from the groove 119 in the lock shell 11.

  • the drive projection 131 will engage the end wall 1911 of the sleeve member 191 to thereby transmit rotation of the drive plate 13 to the latch actuator 18.
  • Figure 7 illustrates a state where the key 30 is capable of driving the locking plates 14 to their unlocking states but is not provided with the correct actuating tip portion 31 (see Figure 1) for driving rotation of the drive plate 13. It should be noted that the inner shell 12 at this time is prevented by the second control rod 125 from rotation within the lock shell 11. As it is necessary to dispose the two control rods 123, 125 in their unlocking positions in order to permit rotation of the latchactuator 18, the anti-theft effect of the lock apparatus of this invention is enhanced accordingly.
  • the plug 26 is removed, and a tool (not shown), such as a hexagonal wrench, is extended into the aperture 218 to loosen the threaded rod 252.
  • the lock core device 10 is then removed from the core chamber 211 through the opening 2110 in the bottom portion of the padlock housing 21.

  • tiny sand grains 100 may enter the lock core device 10 through the key access hole 114.
  • the spacer plates 15 are made of tetrafluoroethylene polymer and are thus much softer than the locking plates 14 made of stainless steel, the sand grains 100 will be pressed into the surfaces of the spacer plates 15 when the locking plates 14 are rotated during operation, thereby preventing jamming of the locking plates 14 due to the presence of the sand grains 100.
  • the locking plates 14 can rotate smoothly to permit normal functioning of the lock apparatus of this invention even in a windy and dusty environment.
  • the drive plate 13 is disposed in contact with the tetrafluoroethylene polymer sleeve member 191
  • the protective plate 17 is disposed in contact with the tetrafluoroethylene polymer protective sleeve 162 to render the internal components of the lock core device 10 resistant to sand and dust.
