The invention relates to a weather-resistant lock apparatus
that is suitable for use in dusty and wet environments.
In current padlock structures, a padlock body 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. However,
in a conventional padlock, as clearances or gaps are present between the padlock
housing and the shackle after assembly, and as 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. For instance, if 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. Moreover, if
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. Furthermore, if
the padlock is used in cold climates, any moisture that gets into the interior of
the padlock may lead to freezing of the internal components, thereby rendering the
padlock inoperable. Although the 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.

Before the present invention is described in greater detail,
it should be noted that like elements are denoted by the same reference numerals
throughout the disclosure.
Referring to Figures 1 to 4, the weather-resistant lock
apparatus according to the present invention 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 key 30 has an actuating tip portion 31 at a foremost end, and a plurality of
key bit portions 32 that are provided on a shank portion of the key 30 and that
form different predetermined angles with the shank portion.
The lock core device 10 is of the type disclosed in, for
example,
U. S. Patent Nos. 5, 934, 121
and
6,185,966
, the entire disclosures of which are incorporated herein by reference.
As shown in Figures 1 and 2, the lock core device 10 includes a lock shell 11 and
a lock core unit. The lock core unit includes an inner shell 12, a drive plate 13,
a plurality of locking plates 14, a plurality of annular spacer plates 15, a sealing
member 16, a protective plate 17, a latch actuator 18, and a rotation control member
191.
The lock shell 11 has a substantially rectangular head
end 111 and a hollow interior confining a receiving chamber 112. The head end 111
has a square end face 113, and is formed with a key access hole 114 extending through
the end face 113 and communicated with the receiving chamber 112. The end face 113
is formed with a beveled periphery 115. An insert groove 116 is formed in a lateral
side of the head end 111. A retaining groove 117 is formed in a peripheral surface
of the head end 111 for receiving a seal member 118 fittingly therein. In this embodiment,
the seal member 118 is shaped as a rectangular loop. Since the seal member 118 and
the beveled periphery 115 are configured to conform to the contour or shape of the
head end 111, if the head end 111 is circular in shape, the seal member 118 and
the beveled periphery 115 will be circular accordingly.
The inner shell 12 is received in the receiving chamber
112, is rotatable relative to the lock shell 11, and has a hollow interior confining
an axial hole 121 for receiving, in sequence, the drive plate 13, the locking plates
14, the spacer plates 15, and the sealing member 16. The inner shell 12 has a tubular
wall that is formed with a first slot 122 corresponding in position to the locking
plates 14 for receiving a first locking unit in the form of a first control rod
123, and a second slot 124 corresponding in position to the drive plate 13 for receiving
a second locking unit in the form of a second control rod 125. The first and second
control rods 123, 125 are operably and respectively associated with the locking
plates 14 and the drive plate 13 so as to be retained between the inner shell 12
and a longitudinal groove 119 formed in an inner surface of the lock shell 11, whereby
rotation of the inner shell 12 relative to the lock shell 11 can be prevented. The
drive plate 13 has an outer periphery provided with a drive projection 131 and a
notch 133, and is further formed with a non-circular drive hole 132 in the center
thereof. In this embodiment, the drive hole 132 is in the shape of three-quarters
of a circle, and is disposed to receive the actuating tip portion 31 of the key
30. It is noted that only when the actuating tip portion 31 of the key 30 matches
the shape of the drive hole 132 will the key 30 be able to drive rotation of the
drive plate 13. The drive hole 132 thus forme a part of a keyhole of the lock core
device 10, and the drive plate 13 thus serves as a code-setting unit of the lock
core device 10. Certainly, the drive hole 132 can be configured to have any other
shape. The locking plates 14 are circular plates made of stainless steel. Each of
the locking plates 14 has an outer periphery formed with a notch 141 at a predetermined
position. Holes formed through the locking plates 14 correspond to the key bit portions
32 of the key 30, and cooperate to form another part of the keyhole of the lock
core device 10 such that the locking plates 14 generally serve as another code-setting
unit of the lock core device 10. The locking plates 14 and the spacer plates 15
are arranged in a stack within the axial hole 121. Each of the spacer plates 15
is disposed between an adjacent pair of the locking plates 14, and serves to maintain
smooth rotation of the locking plates 14. Most importantly, the spacer plates 15
in this invention are made of tetrafluoroethylene polymer, which has a hardness
less than that of the locking plates 14 made of stainless steel, and which is capable
of trapping granules pressed thereinto. Moreover, as tetrafluoroethylene polymer
is known to exhibit lubricating characteristics, it can serve as a substitute for
conventional lubricants. It is noted that the conventional lock core device is often
stained with dirt during lubrication, thereby dirtying the key 30 and obstructing
turning of the key 30. With the use of the tetrafluoroethylene polymer spacer plates
15 in this invention, there is no need for additional lubrication, thus eliminating
the aforesaid problem. The sealing member 16 is disposed at a foremost end of the
inner shell 12, i.e., adjacent to the key access hole 114, and includes a sealing
ring 161 and a protective sleeve 162. The sealing ring 161 is press-fitted within
the axial hole 121 in the inner shell 12. The protective sleeve 162 is also made
of tetrafluoroethylene polymer, and is press-fitted in the receiving chamber 112
of the lock shell 11. The protective sleeve 162 is formed with an annular skirt
1621, which extends into and which is in sleeved engagement with the sealing ring
161. Accordingly, the sealing member 16 can effectively block entry of dust, sand
and water into the interior of the lock core device 10. The protective plate 17
is fitted between the inner shell 12 and the head end 111 of the lock shell 11,
and is in contact with the protective sleeve 162. The protective plate 17 is made
from a high-strength metal alloy, and is capable of idle rotation within the receiving
chamber 112 so as to withstand a drilling action coming from a direction of the
key access hole 114, thereby avoiding destruction of the lock core device 10 due
to the drilling action.
The latch actuator 18 has a coupling portion 181 and an
actuating portion 182. The coupling portion 181 is fitted into the axial hole 121
in a rear end of the inner shell 12. A retaining pin 110 is extended through the
inner shell 12 to secure the coupling portion 181 in place . The coupling portion
181 is formed with a cavity 1811 for receiving the rotation control member 19 therein.
A sleeve member 191, which is also made of tetrafluoroethylene polymer, is mounted
fittingly in the cavity 1811. The sleeve member 191 has a fan-shaped end wall 1911.
The drive projection 131 of the drive plate 13 engages the end wall 1911 so as to
transmit rotation of the drive plate 13 to the latch actuator 18. The end wall 1911
is formed with a shaped hole 1912 therethrough. Like the drive hole 132 in the drive
plate 13, the shaped hole 1912 is also in the shape of three-quarters of a circle.
The rotation control member 19 includes a spring 192 and
a control pin 193 that are disposed in the cavity 1811. The control pin 193 is biased
by the spring 192 toward the drive plate 13. The control pin 193 has a front end
that serves as a stop end 1931, which has a cross section identical to the shape
of the drive hole 132 and the shaped hole 1912. The control pin 193 is further formed
with an axially extending slot 1932 therealong. The retaining pin 110 further extends
through the slot 1932 to limit axial movement of the control pin 193.
In this embodiment, the lock core device 10 is formed as
a detachable module that can be mounted in the padlock body 20. However, it should
be appreciated by those skilled in the art that the lock core device 10 can be also
used in a wide range of other applications, such as in door locks, auxiliary locks,
and other lock apparatuses.
Referring to Figures 3, 4 and 5, the padlock body 20 is
shown to include a padlock housing 21, two seal rings 22, a shackle member 23, a
latch unit in the form of two catch members 24, a securing member 25, a plug 26,
a securing block 27, and a protective block 28.
The padlock housing 21 is substantially oval in cross section,
is formed with a core chamber 211, and has a bottom portion formed with an opening
2110 for access into the core chamber 211. The lock core device 10 is received in
the core chamber 211. The head end 111 of the lock shell 11 is capable of establishing
watertight contact with the bottom portion of the padlock housing 21 through the
seal member 118. The end face 113 of the lock shell 11 projects outwardly of the
opening 2110 in the bottom portion of the padlock housing 21. The padlock housing
21 further has a top portion formed with left and right shackle holes 212, 213.
Two annular grooves 214 are respectively formed in hole-defining walls that respectively
define the shackle holes 212, 213 adjacent to open ends of the shackle holes 212,
213. The seal rings 22 are retained in the shackle holes 212, 213 in the respective
one of the grooves 214. The interior of the padlock housing 21 is configured with
a passage 215 that is disposed at an inner end of the left shackle hole 212 and
that extends in a direction transverse to the left shackle hole 212 toward the core
chamber 211. The padlock housing 21 is further formed with a threaded hole 216 at
an inner end of the right shackle hole 213. The interior of the padlock housing
21 is further configured with a slide way 217 extending transverse to and extending
between the left and right shackle holes 212, 213 and disposed above the core chamber
211. A shackle retainer 210 is mounted in the padlock housing 21 adjacent to the
left shackle hole 212, and has a section extending into the left shackle hole 212.
The shackle member 23 has a U-shaped configuration, and
longer and shorter insert ends 231, 232. In this embodiment, the longer and shorter
insert ends 231, 232 are respectively inserted into the shackle holes 212, 213 such
that airtight contact is established between each of the longer and shorter insert
ends 231, 232 and the padlock housing 21 through the seal rings 22 in the shackle
holes 212, 213. Each of the longer and shorter insert ends 231, 232 is formed with
a retaining groove 233 in an inner side thereof. The longer insert end 231 is further
formed with a straight groove 234 and an annular groove 235. The shackle retainer
210 extends into the straight groove 234 and the annular groove 235 to prevent removal
of the shackle member 23 from the padlock housing 21 in an unlocked state of the
shackle member 23, as best shown in Figure 8.
The catch members 24 are disposed in the slide way 217.
Each of the catch members 24 has an axial pin 241 for coupling with the actuating
portion 182 (see Figure 1) of the latch actuator 18. When the correct key 30 is
inserted into the lock core device 10 to rotate the latch actuator 18, the catch
members 24 will be brought to engage or disengage the retaining grooves 233 in the
longer and shorter insert ends 231, 232 of the shackle member 23, respectively.
The securing member 25 is disposed in the padlock housing
21 adjacent to the lock core device 10. The securing member 25 includes a nut 251
and a threaded rod 252. The nut 251 is embedded in the padlock housing 21 for threaded
engagement with the threaded rod 252. The threaded rod 252 extends through the nut
251, and is capable of being tightened so as to abut against the lock core device
10 and retain the lock core device 10 in the core chamber 211. The padlock housing
21 is further formed with an aperture 218 that is aligned with the threaded rod
252. The aperture 218 normally receives the plug 26, which serves to close the aperture
218 to prevent entry of foreign objects into the padlock housing 21 through the
aperture 218.
The securing block 27 is disposed in the passage 215. One
side of the securing block 27, which is adjacent to the left shackle hole 212, is
formed with a curved guiding surface 271. The longer insert end 231 of the shackle
member 23 abuts against the guiding surface 271 to urge the securing block 27 to
displace toward the lock core device 10, thereby tightening the securing block 27
against the lock core device 10 so as to retain the lock core device 10 in the core
chamber 211. Another side of the securing block 27, which is adjacent to the core
chamber 211, is formed with a protruding portion 272 for engaging the insert groove
116 in the lock shell 11 of the lock core body 10, as best shown in Figure 5.
The protective block 28 is disposed in the right shackle
hole 213 in the padlock housing 21, and has a height that complements the length
of the shorter insert end 232 of the shackle member 23. The protective block 28
is formed with a fastener hole 281 registered with the right shackle hole 213 therethrough.
A screw 282 is inserted through the fastener hole 281 to engage the threaded hole
216, thereby mounting removably the protective block 28 in the padlock housing 21.
The protective block 28 has a top portion provided with a flange 283 to support
the catch member 24 at the right side of the padlock housing 21. The protective
block 28 is made of a hard metal alloy, and is disposed at a lateral side of the
lock core device 10 so as to resist a drilling action coming from a lateral direction,
thereby avoiding destruction of the lock core device 10 due to the drilling action.
The foregoing is a description of the major components
of the weather-resistant lock apparatus according to this invention, and their relative
structural relationships and positions. The locking and unlocking operations, as
well as the intended effects, of this invention will be described in the succeeding
paragraphs.
Referring to Figure 5, in a locking state, the longer and
shorter insert ends 231, 232 of the shackle member 23 are inserted in the shackle
holes 212, 213 in the padlock housing 21, and are prevented from outward displacement
by the catch members 24 of the latch unit. The lock core device 10 is retained in
the padlock housing 21 by the securing member 25 that abuts theregainst. As 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. In addition, as a
lower edge of the longer insert end 231 of the shackle member 23 urges the securing
block 27 to engage the insert groove 116 in the lateral side of the head end 111
of the lock shell 11, the lock core device 10 is firmly retained in the padlock
housing 21 at this time.
Referring to Figures 1 and 6, in the locking state, 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.
When it is desired to unlock the lock apparatus of this
invention, the correct key 30 has to be inserted into the keyhole of the lock core
device 10. Referring to Figures 1 and 8, 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. Moreover, the actuating tip portion 31 of the
key 30 is inserted into the drive hole 132 in the drive plate 13 to push the control
pin 193 against biasing action of the spring 192 to disengage from the drive plate
13 such that the drive plate 13 is rotatable with the key 30 to an unlocking state
where the second control rod 125 is able to extend into the notch 133 in the drive
plate 13 and thereby disengage from the groove 119 in the lock shell 11. At this
time, the inner shell 12 will no longer be restricted by the first and second control
rods 123, 125 and will be capable of rotation within the lock shell 11. When the
drive plate 13 is rotated by the key 30, 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 inordertopermit
rotationof the latch actuator 18, the anti-theft effect of the lock apparatus of
this invention is enhanced accordingly.
Referring to Figure 9, when the latch actuator 18 rotates
as described hereinabove, due to the coupling between the actuating portion 182
(see Figure 1) of the latch actuator 18 and the catch members 24, the catch members
24 are respectively disengaged from the retaining grooves 233 in the longer and
shorter insert ends 231, 232 of the shackle member 23, thereby enabling the entire
shackle member 23 to be pulled upwardly relative to the padlock housing 21. At this
time, the longer insert end 231 of the shackle member 23 is blocked by the shackle
retainer 210 from being uprooted completely from the left shackle hole 212, whereas
the shorter insert end 232 can be removed completely from the right shackle hole
213. When the shackle member 23 is in an unlocked state, the longer insert end 231
no longer shields the threaded rod 252, and the securing block 27 is no longer urged
by the longer insert end 231 toward the lock shell 11.
In the aforesaid unlocked state, the components of the
lock apparatus of this invention can be dismantled in the following sequence:
First, 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.
After the lock core device 10 has been removed, a tool
(not shown) is extended into the right shackle hole 213 to loosen the screw 282
in the protective block 28 and to remove the screw 282 from the threaded hole 216.
The protective block 28 can be removed from the padlock housing 21 through the opening
2110 in the bottom portion of the padlock housing 21 at this time.
Thereafter, the catch members 24 can be removed from the
padlock housing 21 through the opening 2110 in the bottom portion of the padlock
housing 21.
Subsequently, the shackle retainer 210 and the securing
block 27 are removed from the padlock housing 21, also through the opening 2110
in the bottom portion of the padlock housing 21.
Finally, the shackle member 23 is disassembled from the
padlock housing 21.
As all of the internal components of the lock apparatus
of this invention are detachable, defective or damaged components can be conveniently
removed, and replacement components can be installed with relative ease by conducting
the foregoing steps in a reverse order.
Referring to Figure 10, when the weather-resistant lock
apparatus of this invention is used in a wet and humid environment, water may accumulate
on the top portion of the padlock housing 21 at the open ends of the shackle holes.
However, since the shackle holes are provided therein with the seal rings 22 to
establish an airtight and watertight seal with the shackle member 23, water cannot
enter into the padlock body 20 through the shackle holes, thereby avoiding rusting
of components inside the padlock housing 21. Moreover, since water can be prevented
from entering into the padlock body 20, the internal components are not likelytobecome
frozen in cold climates so as not to affect normal operation of the lock apparatus
of this invention.
Referring to Figure 11, when the weather-resistant lock
apparatus of this invention is exposed to a wet and humid environment, water may
flow along the bottomportion of the padlock housing 21 and reach the lock core device
10. However, since the end face 113 of the lock shell 11 of the lock core device
10 projects outwardly of the padlock housing 21 and is provided with the beveled
periphery 115, when the water reaches the beveled periphery 115, it will be stopped
to accumulate thereat and eventually drop to the ground. Therefore, water can be
prevented from entering through the key access hole 114 in the lock shell 11 and
into the lock core device 10.
Referring to Figure 12, when the weather-resistant lock
apparatus of this invention is used in a windy and dusty environment, tiny sand
grains 100 may enter the lock core device 10 through the key access hole 114. However,
because 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. In other words, 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. Similarly, as shown in Figure 2,
the drive plate 13 is disposed in contact with the tetrafluoroethylene polymer sleeve
member 191, and 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.
Figure 13 illustrates the second preferred embodiment of
the weather-resistant lock apparatus according to this invention, which is a modification
of the previous embodiment. Like the previous embodiment, a padlock housing 21'
has a lock core device 10, two catch members 24, and a securing block 27 mounted
therein. The padlock housing 21' has two shackle guards 211' extending therefrom
to protect a shackle member 23', and further accommodates a protective block 28'
therein. The shackle member 23' has two insert ends 231' that are of equal length,
and the fastener hole 281' in the protective block 28' is modified to receive one
of the insert ends 231' . As the shackle retainer 210 (see Figure 5) of the previous
embodiment is not provided in the padlock housing 21', in an unlocked state, the
shackle member 23' can be removed entirely from the padlock housing 21'.
