BACKGROUND
1. Technical Field
[0001] The present disclosure relates to a lockset, and more particularly, to a lock device
and an actuation method of a lockset.
2. Description of Related Art
[0002] In order to prevent theft and intrusion, a conventional emergency exit can usually
be locked from inside with a key.
[0003] However, during emergency evacuation, a person has to find the right key for the
door, unlock the door, and push open the door before egress. This results in a lot
of precious time being wasted and is not conducive to swift evacuation.
[0004] Therefore, there is a need for a solution that addresses the aforementioned shortcomings
in the prior art.
SUMMARY
[0005] In view of the aforementioned shortcomings of the prior art, the present disclosure
provides a lock device, which may include: a housing with an accommodating space;
a main lock head arranged at one side of the housing and capable of sliding into or
out of the accommodating space; and a lock assembly arranged in the accommodating
space to actuate the main lock head. The lock assembly may include an active member
secured to the main lock head, a drive member capable of actuating the active member,
a control structure linked with the drive member, a passive structure provided on
the housing in a displaceable manner, and an action member linked with the passive
structure.
[0006] In the lock device above, the drive member is pivotally connected to the housing.
[0007] In the lock device above, the control structure includes a control port to pivotally
connected to the housing.
[0008] In the lock device above, the passive structure is a reciprocating structure.
[0009] In the lock device above, the action member is pivotally connected to the housing,
one side of the action member functioning as an action portion that actuates correspondingly
with the passive structure, and another side of the action member functioning as a
limiter that actuates correspondingly with the active member.
[0010] The lock device above may further include an idle-run assembly arranged in the accommodating
space, which may include an actuating member provided on the housing in a displaceable
manner, a toggle member pivotally connected to the housing, a pushing member provided
on the control structure in a displaceable manner, and a passive member provided on
the control structure. For example, the passive member is formed with an idle-run
recess capable of engaging with or disengaging from the pushing member.
[0011] The lock device above may further include a safety assembly arranged in the accommodating
space, and a safety bolt and an auxiliary bolt provided on the housing, wherein the
safety assembly includes a first active member provided on the housing in a displaceable
manner to displace the safety bolt along with the first active member, a second active
member provided on the housing in a displaceable manner to displace the auxiliary
bolt along with the second active member, and a cam member linked with the first and
second active members. For example, the cam member may include a hook portion for
releasing or fixating the first active member. For example, the drive member may include
a drive stop block capable of abutting against the cam member for actuating or stopping
the cam member.
[0012] The present disclosure also provides an actuation method of a lockset, which may
include: providing a lockset including a housing and at least one bolt provided on
the housing, and a first target handle and a second target handle disposed at two
opposite sides of the lockset; at a first time point, turning the first target handle
in a first target direction to lock the bolt extending out of the housing to place
the bolt in a locked state; at a second time point, turning the first target handle
in a second target direction to release the bolt from the locked state, thereby retracting
the bolt into the housing and placing the bolt in an unlocked state, wherein the first
target direction is in an opposite direction to the second target direction; and at
a third time point, turning the second handle in a third target direction to bring
the bolt out of the housing to lock the bolt and place the bolt in the locked state,
wherein the first target direction is the same direction as the third target direction.
[0013] In the method above, the first target handle is an indoor handle, and the second
target handle is an outdoor handle.
[0014] In the method above, the first target handle is an outdoor handle, and the second
target handle is an indoor handle. For example, the method includes using a target
key to manipulate the lockset between the first time point and the second time point.
[0015] The method above includes using a target key to manipulate the lockset.
[0016] In the method above, the first target direction is an upward direction in which the
first target handle is turned.
[0017] In the method above, the second target direction is a downward direction in which
the first target handle is turned.
[0018] In the method above, the third target direction is an upward direction in which the
second target handle is turned.
[0019] The present disclosure further provides an actuation method of a lockset, which may
include: providing a lockset including a housing and at least one bolt provided on
the housing; at a first time point, electronically actuating the bolt to extend out
of the housing to lock the bolt and place the bolt in a locked state; at a second
time point, electronically releasing the bolt from the locked state, thereby retracting
the bolt into the housing and placing the bolt in an unlocked state, and at a third
time point, electronically actuating the bolt to extend out of the housing to lock
the bolt and place the bolt in a locked state.
[0020] In the method above, the lockset is provided with an induction assembly linked to
the bolt.
[0021] In the two methods above, the lockset is the aforementioned lock device.
[0022] From the above, it can be seen that the lock device and the actuation method of a
lockset of the present disclosure, with the configuration of the lock assembly, usually
allows the emergency exit to be locked with the target key to prevent intruders from
breaking in, but also allows the emergency exit to be unlocked during an emergency
by simply turning the control structure without the need for the target key. Therefore,
an emergency exit including the lock device in accordance with the present disclosure
not only prevents intrusion but also facilitates fast evacuation.

by the present disclosure.
[0026] FIGs. 1A, 1B and 1C are schematic views illustrating a lock device 1 in accordance
with the present disclosure. As shown in FIGs. 1A and 1B, the lock device 1 is a metal
product, which includes a housing 1', at least one main lock head 10, and a lock assembly
2.
[0027] In an embodiment, the directions of a door entry and exit (or the directions of insertion
and removal of a target key 9 as shown in FIGs. 1A and 1D) are defined as the front
and back directions (along a X axis); the extension and retraction of the main lock
head 10 are defined as the left and right directions (along a Y axis); and the directions
along the side of a face plate are defined as the up and down directions (along a
Z axis). It should be noted that the orientations of these directions are merely chosen
to illustrate this embodiment, and there is no particular limits.
[0028] The housing 1' includes a case body 1a, a side plate 1b provided on the case body
1a, and a cover plate 1c covering the case body 1a.
[0029] In an embodiment, the case body 1a is in the form of a rectangular receptacle, which
includes an accommodating space S for accommodating the lock assembly 2. For example,
a key hole 100 is formed at the bottom face of the case body 1a to allow the entry/exit
of a target key 9 into/out of the case body 1a.
[0030] Moreover, the side plate 1b is provided on the left-hand side of the case body 1a,
and the main lock heads 10 are positioned such that the main lock heads 10 can slide
in and out of the accommodating space S. For example, the side plate 1b is in the
shape of a flat rectangular piece with two ends protruding from the upper and lower
surfaces of the case body 1a, respectively. Specifically, at least one safety bolt
11 and at least one auxiliary bolt 12 can be provided on the side plate 1b based on
needs.
[0031] Moreover, the cover plate 1c is a rectangle plate, which covers the front of the
case body 1a to enclose the accommodating space S. For example, the cover plate 1c
includes a key hole 100 (for insertion and removal of the target key 9 into and from
the case body 1a) and a handle hole 101 that are separately provided, and the handle
hole 101 is to be installed with a pivoted handle, which is used as an outdoor handle
8.
[0032] The main lock heads 10 are a plurality of bars, the safety bolt 11 resembles a tongue
shape (i.e., a lock tongue), and the auxiliary bolt 12 resembles a triangular prism
(i.e., a lock tongue).
[0033] In an embodiment, the main lock heads 10, the safety bolt 11, and the auxiliary bolt
12 are arranged in accordance with the European Union standards. The safety bolt 11
and the auxiliary bolt 12 are arranged between the main lock heads 10 with two main
lock heads 10 provided below the safety bolt 11 and two main lock heads 10 above the
auxiliary bolt 12. It should be appreciated that there are numerous types of arrangements
of the bolts, such as those in accordance with the U.S. and other standards, and the
present disclosure is not limited to the above.
[0034] As shown in FIGs. 2A to 2D, the lock assembly 2 includes an active member 20 secured
to the main lock heads 10, a drive member 21 capable of actuating the active member
20, a control structure 2a linked with the drive member 21, a passive structure 2b
provided on the case body 1a in a displaceable manner, and an action member 24 linked
with the passive structure 2b, where the lock assembly 2 can be provided with an auxiliary
structure 2c linked with the control structure 2a based on needs.
[0035] In an embodiment, the active member 20 is provided on the case body 1a in a displaceable
manner, such that the main lock heads 10 can be displaced along with the active member
20. A stepped stop portion 20a is formed at one of the corners of the active member
20 (as shown in FIG. 2B). For example, the active member 20 can be a horseshoe- or
U-shaped flat plate with two leg plates (as shown in FIG. 2B), wherein one of the
leg plates is provided with a main guide rod 200, and a main guide rail 102 in the
form of a linear groove for engaging the main guide rod 200 is formed at the bottom
face of the case body 1a (as shown in FIG. 2B). The stop portion 20a is located at
the corner of the other leg plate of the active member 20. Specifically, a first reciprocating
rod 104 fitted with a first reciprocating spring 104a is provided on a side face of
the case body 1a, and the first reciprocating rod 104 is inserted into a main reciprocating
hole portion 20b on the other leg plate of the active member 20, such that the main
reciprocating hole portion 20b of the active member 20 can move back and forth along
the first reciprocating rod 104 in cooperation with the movements of the first reciprocating
spring 104a.
[0036] Furthermore, the drive member 21 is in the form of a swing arm (as shown in FIGs.
2B and 2C), which is pivotally connected to the bottom face of the case body 1a. The
control structure 2a is a structure having stacked cam disks, and is pivotally connected
to the bottom face of the case body 1a with a square control port 22 at the center
of the cam disks as a pivot point. For example, a shorter first arm 211 and a longer
second arm 212 extending from a drive spindle 210 (fitted with a drive torsional spring
210a for reciprocating motions as shown in FIG. 2B) of the drive member 21. The control
structure 2a includes a plurality of stacked first cam disks 22a and second cam disks
22b secured at relative different heights (as shown in FIGs. 2B and 2B'), and the
control port 22 is exposed from the handle hole 101 for installing the outdoor handle
8 thereon (as shown in FIG. 1A). Specifically, the first cam disks 22a and the second
cam disks 22b are stacked together in a symmetrical manner (the first cam disks 22a
being at the outermost sides as shown in FIG. 2B', such that the lock/unlock actuation
principles are more or less similar from outdoor and indoor). An upright drive plate
211a is formed extending from the first arm 211 in an upright direction, and a control
tab 220 extending outwardly from the periphery of the first cam disks 22a is formed
for abutting against the drive plate 211a. As such, when the control structure 2a
is turned via the control port 22 by the outdoor handle 8, the control tab 220 pushes
the drive plate 211a, which in turn turns the drive member 21.
[0037] In addition, the passive structure 2b is a reciprocating structure, which includes
at least one guide member 23a and at least one elastic member 23b (e.g., a spring).
The two ends of the elastic member 23b are connected with the guide member 23a and
a wall of the case body 1a, respectively, which results in the reciprocating motions
of the guide member 23a. For example, the guide member 23a includes at least one guide
groove 230, as shown in FIG. 2B' and FIG. 2C, and at least one guide rod 103 engaging
the guide groove 230 is formed on the bottom face of the case body 1a, such that the
guide groove 230 cooperates with the guide rod 103 to move the guide member 23a in
a linear fashion. The elastic member 23b limits the guide member 23a to generate linear
back and forth movements.
[0038] Furthermore, an auxiliary structure 2c is also a reciprocating structure, which consists
of the same elements as those of the passive structure 2b, i.e., including the arrangements
of a guide member 23a', an elastic member 23b', guide groove 230', and guide rod 103',
etc. As shown in FIGs. 2A, 2B' and 2C, the outdoor handle 8 can perform reciprocating
action of opening and closing via the control structure 2a and the auxiliary structure
2c. For example, a first control column 221 extending over the second cam disk 22b
is formed on the periphery of the first cam disk 22a (or the control structure 2a
includes a second control column 221' directly linked with the control port 22, and
the second control column 221' corresponds to the first control column 221 and abuts
against the auxiliary structure 2c). As shown in FIG. 2B', when the outdoor handle
8 turns in one direction, the control structure 2a is turned, such that the first
control column 221 (or the second control column 221') pushes the auxiliary structure
2c to move linearly (as indicated by a pushing direction B1 shown in FIG. 2B'). On
the other hand, when the outdoor handle 8 turns in another direction, the control
structure 2a is turned, such that the first control column 221 (or the second control
column 221') pushes the passive structure 2b to move linearly (as indicated by a pushing
direction B2 shown in FIG. 2B').
[0039] Furthermore, the action member 24 is a block of a generally isosceles triangular
shape with an action spindle 240 provided at the center of the action member 24 (as
shown in FIG. 2C) so as to be pivotally connected to the bottom face of the case body
1a. For example, one corner of the action member 24 is an action portion 241, while
the other corner acts as a limiter 242. Specifically, the action spindle 240 is fitted
with a reciprocating mechanism (as indicated by an action torsional spring 240a shown
in FIG. 2C), the limiter 242 actuates corresponding to the stop portion 20a of the
active member 20, and the action portion 241 actuates corresponding to the guide member
23a of the passive structure 2b. As such, the guide member 23a can be formed with
a guide/control portion 231 that cooperates with the action portion 241 (as indicated
by a stepped portion in FIG. 2D acting as a slide).
[0040] When the target key 9 actuates the lock assembly 2 (during normal use), that is,
the target key 9 is inserted into the key hole 100 and turned to move the active member
20, the main guide rod 200 is displaced linearly along the main guide rail 102, so
that the first reciprocating spring 104a of the first reciprocating rod 104 cooperates
with the active member 20 to move the main lock heads 10 along in a linear fashion,
thus allowing the main lock heads 10 to protrude out of or withdraw into the side
plate 1b (i.e., to exit or enter into the accommodating space S of the case body 1a),
and the locations of the main lock heads 10 can be in a locked position as shown in
FIG. 2D or in an unlocked position as shown in FIG. 2D'.
[0041] Furthermore, after a door is locked by the target key 9 (i.e., when the main lock
heads 10 are in the locked position in FIG. 2D), the door can be unlocked by the outdoor
handle 8 without using the target key 9. Specifically, a user turns the outdoor handle
8, which rotates the control structure 2a (in a direction R1 in FIG. 2D) and pushes
the auxiliary structure 2c. This allows the control tab 220 to push the drive plate
211a, which in turns moves the drive member 21, so that the second arm 212 of the
drive member 21 drives (as indicated by an action direction F1 shown in FIG. 2D) the
main guide rod 200 to move linearly along the main guide rail 102. The first reciprocating
spring 104a of the first reciprocating rod 104 is thus depressed by the active member
20, and the main lock heads 10 are displaced linearly to be withdrawn back into the
accommodating space S of the case body 1a (as shown in FIG. 2D'). While the main lock
heads 10 are being retracted back into the accommodating space S of the case body
1a, the stop portion 20a of the active member 20 can move pass the action member 24,
and the stop portion 20a is limited by the limiter 242 of the action member 24 (as
shown in FIG. 2D') to inhibit movements the active member 20. Thus, when the user
releases the outdoor handle 8, through the reciprocating mechanism, i.e., the auxiliary
structure 2c moving the outdoor handle 8 and the control structure 2a and the drive
spindle 210 moving the drive member 21, the outdoor handle 8, the control structure
2a, and the drive member 21 will return to their original positions. However, the
active member 20 will stay in the same place without going back to its original position
(as the stop portion 20a is stopped by the limiter 242). As such, the main lock heads
10 remain retracted inside the accommodating space S of the case body 1a, such as
in the unlocked state shown in FIG. 2D', and the user can subsequently push the door
open without operating the outdoor handle 8.
[0042] It can be appreciated that the principles of actuations for locking and unlocking
the door from outside and inside are essentially the same, so the lock assembly 2
can be actuated by an indoor handle 8' (as shown in FIG. 1A) in the same way.
[0043] Therefore, when the lock assembly 2 of the present disclosure is applied to an emergency
exit, the door can usually be locked using the target key 9 to prevent intruders from
breaking in. In an emergency, an evacuee can open the door by simply turning the indoor
handle 8' and gain access to the outside world without the need of unlocking the door
using the target key 9. Compared to the prior art, the lock device 1 of the present
disclosure, when applied to an emergency exit, can prevent break-ins while making
the door easy to open during emergency situations.
[0044] On the other hand, after evacuation, the main lock heads 10 can be returned into
the locked position by operating the control port 22 without the need to use the target
key 9. Specifically, after the user (e.g., the evacuee) has closed the emergency door
from outside (or after returning indoor), the outdoor handle 8 (or the indoor handle
8') can be used to operate the control port 22 in order to turn it in a specific direction
(indicated by a rotating direction R2 shown in FIG. 2D'), such that the first control
column 221 (or the second control column 221') of the control structure 2a will push
the passive structure 2b to move in a linear fashion (in a pushing direction B2 shown
in FIG. 2D'), which allows the guide/control portion 231 of the guide member 23a to
push the action portion 241 of the action member 24. As a result, action member 24
swings in an action direction F2 shown in FIG. 2D', and the limiter 242 retracts and
is disengaged from the stop portion 20a of the active member 20, thereby allowing
the active member 20 along with the main lock heads 10 to be returned linearly back
to their original positions with the help of the first reciprocating spring 104a of
the first reciprocating rod 104, that is, the main lock heads 10 extend out of the
accommodating space S of the case body 1a (e.g., the state shown in FIG. 2D). Once
the main lock heads 10 protrude from the accommodating space S of the case body 1a,
the action member 24 will be returned to its original position through the restoring
mechanism of the action spindle 240, and the user can then dial back the control port
22, so that the guide member 23a will be returned to its original position through
the elastic member 23b (e.g., back to the state shown in FIG. 2D).
[0045] FIGs. 3A, 3B and 3C are schematic diagrams illustrating a lock device 1 in accordance
with a second embodiment of the present disclosure. The present embodiment is different
from the first embodiment in that an idle-run assembly 3 that disables the operations
of the control structure 2a is further provided, while the rest of the components
are similar and are thus omitted below to avoid repetitions.
[0046] As shown in FIGs. 3A to 3C, the idle-run assembly 3 includes an actuating member
30 provided on the bottom face of the case body 1a in a displaceable manner, a toggle
member 32 pivotally connected on the bottom face of the case body 1a, and a pushing
member 33 provided on the control structure 2a in a displaceable manner, and a passive
member 34 provided on the control structure 2a.
[0047] In an embodiment, the actuating member 30 is in the form of a flat plate. The actuating
member 30 and the active member 20 are stacked on top of each other, as shown in FIG.
2B, and is controlled by the target key 9. For example, an upright tooth portion 30a
is provided on one side of the actuating member 30, and an upright flat actuating
portion 30b is provided on the other side thereof. A tooth opening 300 on the tooth
portion 30a corresponds to a tooth piece 90 of the target key 9 (as shown in FIG.
1D) for moving the actuating member 30. Specifically, at least one (e.g., two) actuating
groove(s) 301 are formed between two sides of the actuating member 30 extending in
a direction that is perpendicular to the direction of the main guide rail 102. At
least one control rod 105 engaged with the actuating groove 301 is provided on the
bottom face of the case body 1a. As such, the actuating member 30 can be displaced
along the arrangement direction of the side plate 1b (indicated by a first actuating
direction C1 shown in FIG. 3B) through the cooperation of the control rod 105 and
the actuating groove 301. On the other hand, the active member 20 can be displaced
along the extension/retraction direction of the main lock heads 10 (indicated by a
second actuating direction C2 shown in FIG. 3B) through the cooperation of the control
rod 105 and a linkage groove 20c of the active member 20 (as shown in FIG. 2B), wherein
the first and second actuating directions C1 and C2 are perpendicular to each other.
[0048] Moreover, the toggle member 32 is in the form of a swing arm, which abuts against
the actuating portion 30b. The toggle member 32 is turned by the actuating portion
30b pushing on it. For example, a first arm 321 and a second arm 322 that are substantially
perpendicular to each other extend outwards from a toggle spindle 320 of the toggle
member 32. The first arm 321 abuts against the actuating portion 30b, while the second
arm 322 abuts against the pushing member 33. Specifically, the second arm 322 is connected
to a pillar 31a disposed on the bottom face of the case body 1a via a spring 31, such
that reciprocating movements of the toggle member 32 can be created.
[0049] In addition, the pushing member 33 has a shape that resembles a mushroom or a screw
that is connected with the second cam disk 22b of the control structure 2a in a displaceable
manner. As shown in FIG. 3C, the pushing member 33 includes an engaging portion 330
(e.g., in the form of a rectangular column) and a hat-shaped force bearing portion
331 at an end of the engaging portion 330. For example, the second cam disk 22b has
an annular body with a control groove 222 that corresponds to the pushing member 33
(as shown in FIG. 3B), so that if the force bearing portion 331 is actuated by the
second arm 322, the engaging portion 330 can be displaced along the direction of the
control groove 222 (indicated by the second actuation direction C2 shown in FIG. 3B)
to access (e.g., enter and exit) the control groove 222 relative to the second cam
disk 22b. Specifically, the engaging portion 330 is fitted with a push-pull spring
33a (as shown in FIG. 3B), and one end of the push-pull spring 33a is secured to the
force bearing portion 331, while the other end is secured to the second cam disk 22b,
so as to create reciprocating movements of the pushing member 33 along the control
groove 222.
[0050] In addition, the passive member 34 is generally in the form of a cylinder (as shown
in FIG. 3C), and is placed inside the ring of the second cam disk 22b. The passive
member 34 is formed with the control port 22 in the middle thereof, and an idle-run
recess 340 provided on the periphery thereof. The engaging portion 330 can engage
with or disengage from the idle-run recess 340. For example, a second control column
221' corresponding to the first control column 221 can be formed on the periphery
of the passive member 34. Specifically, the idle-run recess 340 and the second control
column 221' are arranged on the periphery of the passive member 34 at a perpendicular
direction as shown in FIG. 3C.
[0051] Therefore, a user can push the actuating member 30 towards the control structure
2a (along the actuating direction C shown in FIG. 3A) using the target key 9. The
actuating portion 30b pushes the first arm 321 of the toggle member 32 and turns the
toggle member 32 (in a rotating direction R shown in FIG. 3A). This in turn allows
the second arm 322 to push the force bearing portion 331 of the pushing member 33
(along an action direction P in FIG. 3A). Meanwhile, the engaging portion 330 extends
into the control groove 222 (along an action direction P in FIG. 3A) and engages with
the idle-run recess 340 of the passive member 34. As a result, the passive member
34 can be linked with the first cam disk 22a and the second cam disk 22b through the
pushing member 33, forming a linkage mechanism (as shown in FIG. 3A'). Thus, when
the user turns the passive member 34 via the control port 22, this will sequentially
actuate the pushing member 33, the second cam disk 22b and the first cam disk 22a
(as shown in FIG. 2B'), and the rotation of the first cam disk 22a allows the drive
member 21 to be turned by the control tab 220 (as shown in FIG. 2D). Therefore, the
drive member 21 can be controlled by the outdoor handle 8 (or the indoor handle 8')
through the control structure 2a.
[0052] Moreover, if one wishes to let the outdoor handle 8 become "idle run" (e.g., after
locking), that is, unable to control the drive member 21 through the control structure
2a, the user can move the actuating member 30 away from the control structure 2a using
the target key 9 (in an actuating direction C' shown in FIG. 3A'), so that the actuating
portion 30b is moved back, and the toggle member 32 is turned back (in a rotating
direction R' shown in FIG. 3A') as a result of the reciprocating movements of the
spring 31. This means that the pushing member 33 is retracted (in an action direction
P' shown in FIG. 3A') due to the reciprocating movements of the push-pull spring 33a.
Meanwhile, the engaging portion 330 is disengaged from the idle-run recess 340 of
the passive member 34 and retracted back to the control groove 222, such that the
passive member 34 is no longer linked with the second cam disk 22b (an idle-run state
shown in FIG. 3A). Therefore, when the user rotates the passive member 34 via the
control port 22, the passive member 34 can only move the second control column 221'
towards the pushing direction B1, but cannot move the second cam disk 22b and the
first cam disk 22a as the pushing member 33 is not linked. As such, the first cam
disk 22a cannot move since the control tab 220 will not actuate the drive member 21,
resulting in an idle-run state of the control structure 2a, in other words, the drive
member 21 cannot be controlled by the outdoor handle 8 through the control structure
2a.
[0053] As can be seen from above, an idle-run mechanism of the control structure 2a is achieved
with the arrangement of the pushing member 33 and the passive member 34. If this idle-run
mechanism is not desired (such as in the case of the indoor handle 8'), then the toggle
member 32 can be removed and the pushing member 33 can be permanently engaged with
the passive member 34, i.e., the idle-run function is canceled. Alternatively, the
first cam disk 22a, the second cam disk 22b and the passive member 34 can be formed
integrally (the first and second control columns 221 and 221' formed as one column)
to eliminate the idle-run mechanism (such as in the case of the indoor handle 8').
[0054] FIGs. 4A, 4B, 4C, 4D and 4E are schematic diagrams illustrating a lock device 1 in
accordance with a third embodiment of the present disclosure. The present embodiment
is different from the first embodiment in that a safety assembly 4 for the safety
bolt 11 and the auxiliary bolt 12 is further provided, while the rest of the components
are similar and are thus omitted below to avoid repetitions.
[0055] As shown in FIGs. 4A to 4E, the safety assembly 4 includes a first active member
41 secured to the safety bolt 11, a second active member 42 secured to the auxiliary
bolt 12, and a cam member 40 linked with the first and second active members 41 and
42.
[0056] In an embodiment, the first active member 41 is provided on the case body 1a in a
displaceable manner so as to move the safety bolt 11 along with it. For example, the
first active member 41 is a rectangular flat piece with at least one auxiliary guide
column 410 and a corresponding column 412 provided upright thereon. At least one auxiliary
guide 107 in the form of a linear groove for engaging the auxiliary guide column 410
and the corresponding column 412 is formed on the bottom face of the case body 1a
(as shown in FIG. 4C), such that the first active member 41 can move in a linear fashion.
Specifically, as shown in FIGs. 4B and 4C, a second reciprocating rod 106 fitted with
a second reciprocating spring 106a is provided on the side face of the case body 1a,
and the second reciprocating rod 106 is inserted into an auxiliary reciprocating hole
portion 411 on the other end of the first active member 41, such that the auxiliary
reciprocating hole portion 411 of the first active member 41 can move along the second
reciprocating rod 106 and create reciprocating movements with the help of the extension/contraction
of second reciprocating spring 106a.
[0057] Furthermore, the second active member 42 can be provided on the case body 1a in a
displaceable manner so as to move the auxiliary bolt 12 along with it. For example,
the second active member 42 is in the form of a rod body with one end secured to the
auxiliary bolt 12, while the other end provided with at least one safety guide block
420. At least one safety guide rail 108 in the form of a linear groove for engaging
the safety guide block 420 is formed on the bottom face of the case body 1a (as shown
in FIG. 4D), so as to allow linear displacement of the second active member 42. Specifically,
an arch wall 109 spanning over the second active member 42 is provided at the bottom
face of the case body 1a, and the safety guide block 420 and the auxiliary bolt 12
are located at different sides of the fixed arch wall 109, wherein the second active
member 42 is fitted with a safety spring 42a between the auxiliary bolt 12 and the
fixed arch wall 109, and the two ends of the safety spring 42a can be secured to the
auxiliary bolt 12 and the fixed arch wall 109, respectively, such that the second
active member 42 passes through the fixed arch wall 109 for reciprocating movements
in cooperation with the extension/contraction of the safety spring 42a.
[0058] Moreover, the cam member 40 is in the form a strip that is pivotally connected to
the bottom face of the case body 1a to release the first active member 41 or fix it
in position. In one example, one end of a pivot portion 400 of the cam member 40 is
a fixating portion 401 that abuts between the safety guide block 420 of the second
active member 42 and the fixed arch wall 109, and the other end of the pivot portion
400 of the cam member 40 is a hook portion 402. Specifically, the pivot portion 400
of the cam member 40 is provided with a safety torsional spring 40a with one end secured
by a stand 43 of the hook portion 402 and the other end attached to a fixating rod
109' on the bottom face of the case body 1a, such that the cam member 40 generates
reciprocating movements through the torque of the safety torsional spring 40a, such
that the fixating portion 401 is actuated in cooperation with the second active member
42.
[0059] In addition, a pea-shaped drive stop block 213 is formed on the second arm 212 of
the drive member 21, which abuts against the pivot portion 400 of the cam member 40
in order to actuate or stop the cam member 40.
[0060] Therefore, when the user turns the outdoor handle 8 to turn (indicated by the rotating
direction R1 shown in FIG. 2D) the control structure 2a, the control tab 220 pushes
the drive plate 211a and thus turns the drive member 21, so the second arm 212 of
the drive member 21 pushes (indicated by the action direction F1 shown in FIGs. 2D
and 4C) the main guide column 200 and the auxiliary guide column 410, such that the
corresponding column 412 follows the auxiliary guide column 410 and they move linearly
along the auxiliary guides 107. This allows the first active member 41 to depress
the second reciprocating spring 106a of the second reciprocating rod 106 and linearly
move the safety bolt 11 along with it, so the safety bolt 11 is retracted into the
accommodating space S of the case body 1a. Meanwhile, the drive stop block 213 on
the second arm 212 is disengaged from the pivot portion 400 of the cam member 40,
such that the cam member 40 is turned by the safety torsional spring 40a (in a rotating
direction R3 shown in FIG. 4C), and that the hook portion 402 is hooked onto the auxiliary
guide column 410 in order to fix the first active member 41 (or the safety bolt 11)
in place. Meanwhile, the fixating portion 401 of the cam member 40 will push the safety
guide block 420 of the second active member 42 (in an action direction D shown in
FIGs. 4C and 4E) away from the fixed arch wall 109, so the safety guide block 420
moves linearly along the safety guide rail 108, such that the second active member
42 linearly moves the auxiliary bolt 12 along with it, so the auxiliary bolt 12 is
retracted into the accommodating space S of the case body 1a.
[0061] Moreover, when the user releases the outdoor handle 8, the control structure 2a will
return to its original position, but the drive member 21 will not be actuated (since
the hook portion 402 is hooked to the auxiliary guide column 410, the first active
member 41 is held in place, and the corresponding column 412 inhibits the return of
the drive member 21). Therefore, the safety guide block 420 has to be moved (indicated
by an action direction D' shown in FIG. 4C) via the safety guide rail 108 from the
outside of the bottom face of the case body 1a (e.g., indoor), so that the auxiliary
bolt 12 can extend out of the accommodating space S of the case body 1a by the second
active member 42, and the fixating portion 401 of the cam member 40 is pushed towards
the fixed arch wall 109 (indicated by the action direction D' shown in FIG. 4C), and
the cam member 40 is turned (in a rotating direction R4 shown in FIG. 4C) via the
safety torsional spring 40a, such that the hook portion 402 is unhooked from the auxiliary
guide column 410. Meanwhile, the restoring force of the drive member 21 (i.e., the
torque of the drive torsional spring 210a of the drive spindle 210) exerts a force
(indicated by an action direction F4 shown in FIG. 4C and FIG. 4E) on the corresponding
column 412, such that the safety bolt 11 can spring out of the accommodating space
S of the case body 1a as a result of the first active member 41. It can be understood
that when the drive member 21 is returned to a certain position, the drive stop block
213 will abut with the pivot portion 400 of the cam member 40 to prevent the cam member
40 and its safety torsional spring 40a from moving.
[0062] Therefore, when the drive member 21 brings the main lock heads 10 and the safety
bolt 11 into the accommodating space S of the case body 1a, the safety guide block
420 can be moved to actuate the second active member 42 and allow the cam member 40
to be unhooked, which actuates the drive member 21 to spring out the safety bolt 11
from the accommodating space S of the case body 1a. As a result, even if the main
lock heads 10 are not protruding from the accommodating space S of the case body 1a
(in the state shown in FIG. 2D'), the safety bolt 11 and the auxiliary bolt 12 can
still be extended out of the accommodating space S of the case body 1a.
[0063] On the other hand, since the auxiliary bolt 12 and the second active member 42 can
move independently of (i.e., not linked with) the outdoor handle 8 or the target key
9, when in a locked state (such as the state shown in FIG. 4A), if the safety guide
block 420 is manually moved via the safety guide rail 108 of the case body 1a, only
the auxiliary bolt 12 will be moved back into the accommodating space S of the case
body 1a, the cam member 40 will not be actuated to hook onto the auxiliary guide column
410 (since the fixating portion 401 is situated between the safety guide block 420
of the second active member 42 and the fixed arch wall 109), so the outdoor handle
8 (or the indoor handle 8') is still free to turn. This prevents the outdoor handle
8 (or the indoor handle 8') from locking and not operable during an emergency.
[0064] FIGs. 5A, 5B, 5C, 5D and 5E are schematic diagrams depicting a lock device 1 in accordance
with a fourth embodiment of the present disclosure. The present embodiment is different
from the first embodiment in the design of the indoor handle 8' of the case body 1a
during an emergency, the remainder of the structures are substantially the same and
will not be repeated for conciseness.
[0065] The indoor handle 8' (as shown in FIG. 1A) is pivotally connected to another handle
hole 101' (as shown in FIG. 1C corresponding to the control structure 2a) at the bottom
face of the case body 1a, such that the indoor handle 8' is able to always control
the control structure 2a with no idle-run mechanism as described with respect to FIGs.
3A to 3C. In other words, the idle-run mechanism is not applicable to the indoor handle
8', but rather, the indoor handle 8' is capable of driving the drive member 21 to
actuate the main lock heads 10 (as shown by the actuating methods described with respect
to FIGs. 2D and 2D'), the safety bolt 11 (as shown in FIGs. 4A to 4E) and the auxiliary
bolt 12 to retract into the accommodating space S of the case body 1a to enable fast
emergency escape.
[0066] As shown in FIGs. 5A, 5B, 5C, 5D and 5E, the case body 1a is provided with a regulating
assembly 5a.
[0067] In an embodiment, the regulating assembly 5a includes a regulating member 50 that
is disposed coaxially (e.g., with respect to the drive spindle 210) on the drive member
21 (as shown in FIG. 5D) and at least one regulating column 51 corresponding to the
regulating member 50 and formed on the actuating member 30 (as shown in FIG. 5E),
wherein the regulating member 50 rotates synchronously with the drive member 21, and
the regulating member 50 in rotation pushes the regulating column 51, which in turn
displaces the actuating member 30 (e.g., along the actuating direction C shown in
FIG. 3A or 5B). For example, the regulating member 50 is a curved member with one
end 50a abuts against the drive plate 211a of the first arm 211 of the drive member
21 and another end 50b abuts against the regulating column 51. The regulating column
51 is in the form of a cylinder, such that the regulating member 50 travels around
the circumference of the regulating column 51 after pushing the regulating column
51.
[0068] Moreover, if the regulating mechanism is not in place (i.e., there is no regulating
member 50 and regulating column 51), since the idle-run mechanism is not actuated,
and the actuating member 30 is not manipulated by the target key 9 from indoor, the
active member 20 when displaced (in the action direction F1 shown in FIG. 2D or 5A)
will come into contact with a stop wall 53 of the actuating portion 30b of the actuating
member 30 (as shown in FIG. 5E), thus limiting further movements of the active member
20, as well as movements of the main lock heads 10, the auxiliary bolt 12 and the
safety bolt 11 (i.e., thus stuck in position), so the main lock heads 10, the safety
bolt 11 and the auxiliary bolt 12 will still stay protruded outside the case body
1a.
[0069] Thus, the regulating member 50 pushes the regulating column 51 to displace the actuating
member 30, such that the stop wall 53 of the actuating portion 30b of the actuating
member 30 is moved out of the displacement path of the active member 20, allowing
the active member 20 to displace successfully, and the main lock heads 10, the safety
bolt 11 and the auxiliary bolt 12 to be retracted back into the accommodating space
S of the case body 1a.
[0070] It can be appreciated that the regulating member 50 only needs to push the actuating
portion 30b of the actuating member 30 out of the displacement path of the active
member 20. In other words, the actuating portion 30b only needs to be moved by a relatively
short distance (not actuating the idle-run mechanism) unlike in the case of actuating
the idle-run mechanism (as described with respect to FIGs. 3A to 3C) where the actuating
portion 30b is moved by target key 9 by a relatively longer distance.
[0071] Moreover, when the user releases the indoor handle 8', the control structure 2a returns
to its original position, and the regulating member 50 is rotated back by the drive
torsion spring 210a of the drive spindle 210, such that the stand 43 of the hook portion
402 is pushed by the regulating member 50 so as to push the hook portion 402 away
from the auxiliary guide column 410 (refer to descriptions with respect to FIGs. 4A
to 4E). This allows the fixating portion 401 of the cam member 40 to move towards
the fixed arch wall 109, and in turn, move the auxiliary bolt 12 out of the accommodating
space S of the case body 1a. Meanwhile, the turning force of the drive member 21 (exerted
by the drive torsion spring 210a of the drive spindle 210) pushes the corresponding
column 412 (along the action direction F4 shown in FIGs. 4C and 4E) to pop the safety
bolt 11 out of the accommodating space S of the case body 1a. As a result, both the
safety bolt 11 and the auxiliary bolt 12 can be pushed out of the accommodating space
S of the case body 1a without the need to move the safety guide block 420 at the safety
guide 108 rail.
[0072] FIG. 6A is a flowchart illustrating a first embodiment of an actuation method of
a lockset in accordance with the present disclosure, and FIGs. 6B to 6E are illustrations
of the steps in FIG. 6A.
[0073] In an embodiment, the actuation method of the lockset is with regard to a user moving
from indoor to outdoor, for example, going out, leaving a room, emergency escape,
etc.
[0074] In step S60, a lockset, such as the lock device 1, is provided, which includes a
housing 1' and at least one bolt provided on the housing 1' (e.g., the main lock heads
10, the safety bolt 11 and the auxiliary bolt 12), and a first target handle and a
second target handle are provided on opposite sides of the lockset.
[0075] In an embodiment, the lockset is provided on a door panel 6, and the door panel 6
is in a closed state as shown in FIG. 6B.
[0076] Furthermore, as shown in FIG. 6B, the first target handle is the indoor handle 8',
which can always control the control structure 2a, and the second target handle is
the outdoor handle 8, which is controlled by the idle-run mechanism.
[0077] In step S61, at a first time point (after the user entered the room), the bolt is
protruding from the housing 1', and the indoor handle 8' is turned in a first target
direction A1 to lock the bolt in a "locked" state, which prevents the bolt from being
retracted in the housing 1' by the outdoor handle 8.
[0078] In an embodiment, the first target direction A1 is an upward direction in which the
indoor handle 8' is pushed (or a clockwise rotation from the viewpoint of the user
shown in FIG. 6C), but it can be appreciated that there are numerous types of indoor
handles, such as press handles (in which the first target direction may be lifting
upwards the handle from the viewpoint of the user), and the present disclosure is
not limited as such.
[0079] Furthermore, the indoor handle 8' will reinstate its original position after the
bolt is locked (as shown by the horizontal position in FIG. 6B).
[0080] In step S62, at a second time point (when the user wishes to leave the room), the
indoor handle 8' is turned in a second target direction A2 to release the bolt from
the "locked" state and cause the bolt to retract into the housing 1' so as to be in
an "unlocked" state. At this time, the user can push the door panel 6 to leave the
room.
[0081] In an embodiment, the first target direction A1 and the second target direction A2
are opposite directions. More specifically, the second target direction A2 is a downward
direction in which the indoor handle 8' is moved (or an anticlockwise direction based
from the viewpoint of the user as shown in FIG. 6D), but it can be appreciated that
there are numerous types of indoor handles, such as press handles (in which the second
target direction may be pressing down the handle based on the viewpoint of the user),
and the present disclosure is not limited as such.
[0082] Furthermore, the indoor handle 8' will reinstate its original position after the
bolt is locked (as shown by the horizontal position in FIG. 6B).
[0083] In step S63, at a third time point (after the user left the room and shut the door
panel 6 from outside), the outdoor handle 8 is turned in a third target direction
A3 to cause the bolt to protrude out of the housing 1' and put the bolt in a "locked"
state.
[0084] In an embodiment, the first target direction A1 and the third target direction A3
are the same directions. More specifically, the third target direction A3 is an upward
direction in which the outdoor handle 8 is moved (or an anticlockwise rotation from
the viewpoint of the user shown in FIG. 6E), but it can be appreciated that there
are numerous types of outdoor handles, such as press handles (in which the third target
direction may be lifting upwards the handle from the viewpoint of the user), and the
present disclosure is not limited as such.
[0085] Furthermore, the outdoor handle 8 will reinstate its original position after the
bolt is locked (as shown by the horizontal position of the indoor handle 8' in FIG.
6B).
[0086] Moreover, when the lock device 1 is locked, the idle-run mechanism is enabled, which
means that the door cannot be unlocked by the outdoor handle 8.
[0087] FIG. 7A is a flowchart illustrating a second embodiment of an actuation method of
a lockset in accordance with the present disclosure, and FIGs. 7B to 7E are illustrations
of the steps in FIG. 7A. This embodiment is different from the first embodiment in
the scenario in which the lockset is used, so those that are similar or the same will
not be repeated below.
[0088] In an embodiment, the actuation method of the lockset is with regard to a user moving
from outdoor to indoor, for example, returning home, entering a room, or the like,
and the first target handle is the outdoor handle 8 and the second target handle is
the indoor handle 8'.
[0089] In step S70, at a first time point (after the user has left the room and closed the
door panel 6 from the outside), the bolt is protruding from the housing 1', and the
outdoor handle 8 is turned in a first target direction A1' (as shown in FIG. 7B) to
lock the bolt in a "locked" state.
[0090] In an embodiment, when the lock device 1 is locked, the idle-run mechanism is enabled,
and the door cannot be unlocked by the outdoor handle 8.
[0091] In step S71, the lock device 1 is manipulated by the target key 9 (as shown in FIG.
7C) to disable the idle-run mechanism of the lock device 1, such that the control
structure 2a can be controlled by the outdoor handle 8.
[0092] In step S72, at a second time point (the user wishes to enter the room), the outdoor
handle 8 is turned in a second target direction A2' (as shown in FIG. 7D) to release
the bolt from the "locked" state, so that the bolt retracts into the housing 1' and
becomes "unlocked." At this time, the user can pull the door panel 6 in order to enter
into the room.
[0093] In an embodiment, the first target direction A1' and the second target direction
A2' are opposite directions.
[0094] In step S73, at a third time point (after the user has entered the room and shut
the door panel 6 from inside), the indoor handle 8' is turned in a third target direction
A3' (as shown in FIG. 7E) to cause the bolt to extend out of the housing 1' and the
bolt is in a "locked" state.
[0095] In an embodiment, the first target direction A1' and the third target direction A3'
are the same directions.
[0096] Therefore, the lock device 1 of the present disclosure can be used for household
door locks, where the outdoor handle 8 and the indoor handle 8' are disposed at the
two opposite sides, the side on which the key hole 100 of the target key 9 and its
corresponding outdoor handle 8 are provided is the outside, and the side on which
the indoor handle 8' is provided is the inside. When the lock device 1 is in the "locked"
state, the user can quickly evacuate during an emergency by simply pushing down the
indoor handle 8' (in the second target direction A2 shown in FIG. 6D) to open the
door without the need to use a key or turn any parts.
[0097] FIG. 8 is a flowchart illustrating a third embodiment of an actuation method of a
lockset in accordance with the present disclosure, and FIG. 8' is an illustration
of FIG. 8. This embodiment is different from the previous embodiments in the form
of the lockset, so those that are similar or the same will not be repeated below.
[0098] In step S80, an electronic lock is provided as the lockset.
[0099] In an embodiment, an inductive assembly 8" is provided in the accommodating space
S of the lock device 1, so that the lock device 1 becomes an electronic lock, in which
the bolt can be actuated by the inductive assembly 8". For example, the inductive
assembly 8" includes a circuit board 80, a motor 81 electrically controlled by the
circuit board 80, and related mechanism (not shown) driven by the motor 81 as shown
in FIG. 8'. It can be appreciated that there are numerous types of electronic lock,
and the present disclosure is not limited as such.
[0100] In step S81, at a first time point, the bolt is actuated to extend out of the housing
1' via electronic control (e.g., via an induction key) to lock the bolt in a "locked"
state.
[0101] In step S82, at a second time point, the bolt is retracted into the housing 1' via
electronic control (e.g., via the induction key) to put the bolt in a "unlocked" state.
[0102] In step S83, at a third time point, the bolt is actuated to extend out of the housing
1' via electronic control (e.g., via the induction key) to lock the bolt in a "locked"
state.
[0103] It can be appreciated that there are numerous ways to actuate the electronic lock,
and the present disclosure is not limited to the induction key. Moreover, the steps
S81 to S83 are applicable to a scenario in which a user wishes to leave the room or
go outside.
[0104] Accordingly, in the electronic lock of the present disclosure, depending on the evacuation
requirements, the actuation function of the outdoor handle 8 can be replaced by the
induction key, and the indoor handle 8' is used inside, which means after the lock
device 1 is locked, the user can quickly escape during an emergency by simply pushing
down the indoor handle 8' (in the second target direction A2 shown in FIG. 6D) to
open the door without the need to use the induction key.
[0105] In summary of the above, the lock device 1 of the present disclosure, with the configuration
of the lock assembly 2, usually allows the emergency door to be locked to prevent
intruders from breaking in, but also allows the door to be opened during an emergency
by simply turning the indoor handle 8' (i.e., turning the control structure 2a) without
