This application claims priority to Taiwan Application Serial No. 109210968, filed on Aug. 24, 2020. The entirety of the application is hereby incorporated by reference herein and made a part of this specification.
The present disclosure relates to door lock devices, and more particularly, to a door lock device capable of generating an idle state.
Conventionally, a door lock is disposed on a door plate and provided with a handle. A user can rotate the handle to operate the door lock, thereby going into or out of a room.
Referring to
However, in the conventional door lock device 1, when the door lock device 1 is in a locking state, the rotary handle cannot be rotated due to the restraining effect of the lock tongue 14 being unable to retract. If the rotary handle is forced to rotate at this time, the handle interlocking structure 15 of the door lock device 1 will be damaged. For example, if the rotary handle is impacted by an object or forced to rotate by an unscrupulous person, the handle interlocking structure 15 will be damaged by an improper external force. As such, the door lock device 1 cannot be used normally after being unlocked (i.e., after the lock head 12 is retracted).
Further, the conventional door lock device 1 lacks any fireproof mechanism and cannot meet the requirements of fire doors. Therefore, the door lock device 1 cannot be mounted on a fire door. For example, in the case of a fire in a building, the door lock device 1 cannot be forced to lock. As such, when the fire spreads, the fire door that prevents the fire from spreading indoors may be mistakenly opened by an indoor person, thereby introducing a large amount of air indoors and causing the fire to rush indoors. Consequently, not only the indoor person who mistakenly opens the fire door is burned by the rushing fire, but also other indoor persons fall into a sea of fire.
Therefore, how to overcome the above-described drawbacks of the prior art has become critical.
In view of the above-described drawbacks, the present disclosure provides a door lock device, which comprises: a housing having a receiving space; an acting assembly arranged in the receiving space and having a lock tongue; an operating assembly arranged in the receiving space and interlocked with a target handle; and a regulating assembly arranged in the receiving space, wherein when the operating assembly is regulated into an interlocking state through the regulating assembly, the target handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and wherein when the operating assembly is regulated into an idle state through the regulating assembly, the operating assembly is unable to drive the acting assembly and the target handle is unable to be interlocked with the lock tongue.
In an embodiment, the operating assembly has at least one operating mechanism comprising a rotating member engaging with the target handle, a base body disposed around the rotating member, and a sheet body fixed on the base body and disposed around the rotating member. For example, the sheet body has a stop arm for cooperating and actuating with the acting assembly. Alternatively, a sliding slot is formed on a peripheral surface of the base body and in communication with the rotating member. Further, the operating mechanism comprises a sliding block engaging with the sliding slot to abut against or separate from the rotating member along the sliding slot. An elastic element is disposed around the sliding block.
In an embodiment, the acting assembly further comprises a lock tongue base connected to the lock tongue and a fireproof sheet displaceably disposed on the lock tongue base, wherein the fireproof sheet has a security post made of a hot melt material, the security post protrudes into and engages with the lock tongue base, and an acting post is arranged in the receiving space of the housing corresponding to the fireproof sheet.
In an embodiment, the regulating assembly comprises a button pivotally connected to the housing and exposed from the receiving space, a first acting plate and a second acting plate arranged at opposite sides of the button, a rotating sheet axially connected to the housing and passing through the first and second acting plates, an elastic sheet connecting the rotating sheet and the housing, and a rotating plate axially connected to the housing and elastically connected to the rotating sheet, such that in operation, the button is interlocked with one end of one of the first and second acting plates to cause another end of said one of the first and second acting plates to interlock with the rotating plate.
In an embodiment, the regulating assembly comprises a button pivotally connected to the housing and exposed from the receiving space, a rotating plate axially connected to the housing, an electromagnetic valve interlocked with the rotating plate, and a battery actuating the electromagnetic valve, and wherein the button serves as an electrical switch for connecting the battery and the electromagnetic valve through wires.
In an embodiment, the regulating assembly comprises a button pivotally connected to the housing and exposed from the receiving space, a first acting plate and a second acting plate arranged at opposite sides of the button, a rotating sheet axially connected to the housing and passing through the first and second acting plates, and a rotating plate axially connected to the housing and elastically connected to the rotating sheet, and wherein a sleeve is formed at one end of the rotating sheet, and a positioning rod is vertically disposed on the housing and positioned in the sleeve, such that when the rotating sheet swings, the sleeve collides with the positioning rod.
In an embodiment, the regulating assembly comprises a rotating plate axially connected to the housing and an electromagnetic valve interlocked with the rotating plate.
According to the door lock device of the present disclosure, the operating assembly is regulated into the interlocking state or the idle state through the regulating assembly. As such, when the target handle serves as an outdoor handle, a user can regulate the operating assembly and the outdoor handle into the idle state so as not to interlock the operating assembly and the acting assembly. Therefore, compared to the prior art, the outdoor handle cannot operate the lock tongue when the door lock device of the present disclosure is locked. Hence, if the outdoor handle is forced to rotate (for example, impacted by an external force or forced to rotate by an unscrupulous person), neither the operating assembly nor the acting assembly will be affected (i.e., the lock tongue maintains a good locking state), thus avoiding damage of the operating assembly and ensuring safe and normal use of the door.
Further, since the security post is made of a hot melt material, the security post will melt when the door lock device is at high temperature. Consequently, the fireproof sheet covering the lock tongue base falls down due to its own weight and comes into contact with the acting post. As a result, the acting assembly is stuck and cannot be interlocked with the lock tongue. Therefore, when the door lock device is locked, in case of an outdoor fire, the security post will melt so as to prevent the acting assembly from being interlocked with the lock tongue, thus preventing the door from being opened and achieving a fire isolation effect and further preventing an indoor person from mistakenly opening the door. Therefore, the door lock device complies with the fire safety regulations and can be applied to the configuration of fire doors.
The following illustrative embodiments are provided to illustrate the present disclosure, these and other advantages and effects can be apparent to those in the art after reading this specification.
It should be noted that all the drawings are not intended to limit the present disclosure. Various modifications and variations can be made without departing from the spirit of the present disclosure. Further, terms such as “up,” “first,” “second,” “third,” “a,” etc., are merely for illustrative purposes and should not be construed to limit the scope of the present disclosure.
In an embodiment, a front or rear direction such as an arrow direction X is defined along an extending or retraction direction of a lock head 201 of the door lock device 2, a left or right direction such as an arrow direction Y is defined along a height direction of the door lock device 2, and an up or down direction such as an arrow direction Z is defined along a thickness direction of the door lock device 2. It should be noted that the orientations of the arrow directions X, Y and Z are used for illustrative purposes and not intended to limit the present disclosure.
Further, referring to
The housing 2a is in the shape of a rectangular box, which has a receiving space S and a cover member (not shown) covering the receiving space S. An acting post 23 (as shown in
In an embodiment, the housing 2a has a key hole 200 communicating with the receiving space S so as for a target key 80 (as shown in
The regulating assembly 2b has a rocker-shaped button 24 exposed from the receiving space S and pivotally connected to the housing 2a (for example, at a shaft joint 240). When one side of the button 24 is pressed, it is inclined toward the other side of the button 24. Further, the regulating assembly 2b has a first acting plate 25 and a second acting plate 26 arranged in the receiving space S and linearly displaceable. As such, either side of the button 24 abuts against one of the first acting plate 25 and the second acting plate 26. Further, a rotating sheet 27 is axially connected to the housing 2a and inserted into holes of the first acting plate 25 and the second acting plate 26. For example, the rotating sheet 27 has triangular cone-shaped ends. One end of the rotating sheet 27 close to the bottom of the housing 2a is connected to the bottom of the housing 2a through an M-shaped bent elastic sheet 28. The elastic sheet 28 applies pressure to the rotating sheet 27 so as to position the rotating sheet 27. As such, the rotating sheet 27 can form a two-stage toggle position by using the elastic sheet 28.
Further, the regulating assembly 2b has a right angle bent rotating plate 29 axially connected to a pivot portion 29a on the housing 2a and corresponding to the first acting plate 25 and the second acting plate 26. In operation, a bent portion 290 on one side of the rotating plate 29 is interlocked with another end of one of the first acting plate 25 and the second acting plate 26. For example, the bent portion 290 of the rotating plate 29 close to the rotating sheet 27 is connected to one end of a spring 22 and the other end of the spring 22 is connected to a shaft portion 27a of the rotating sheet 27. As such, the spring 22 applies a pulling force onto the rotating plate 29 so as to cause the rotating plate 29 to rotate based on the pivot portion 29a.
The first acting assembly 20 has a lock head 201. The lock head 201 is actuated by inserting the target key 80 into the key hole 200 (or through an indoor knob) so as to extend out of or retract into the receiving space S. When the lock head 201 extends out of the receiving space S, the lock head 201 engages with a lock hole (not shown) on the door frame 90 to present a locking state.
The second acting assembly 30 has a security bolt 301. The security bolt 301 can retract into the receiving space S so as to cause the second acting assembly 30 to stop the third acting assembly 40.
The third acting assembly 40 has a lock tongue 401. By rotating at least one target handle 81, 82 disposed on the door body 9 to drive the third acting assembly 40, the lock tongue 401 extends out of or retracts into the receiving space S. When the lock tongue 401 extends out of the receiving space S, the lock tongue 401 engages with a lock tongue hole (not shown) on the door frame 90 so as to present another locking state.

Further, a second bolt slot 504a of a square shape is formed at a center of the second rotating member 504 for axially engaging with the target handle 82 (as shown in
The first sheet body 505 has a ring shape. A circular first through hole 505a is formed at a center of the first sheet body 505 so as to allow the first rotating member 503 to pass therethrough. The first rotating member 503 passes through the first base body 501 and the first sheet body 505 and protrudes from the first sheet body 505 for engaging with the target handle 81. Further, a first stop arm 505b of a bent shape extends from an edge of the first sheet body 505 and abuts against a driving member 404 of the third acting assembly 40. Furthermore, a plurality of circular first openings 505c are formed on a ring body of the first sheet body 505 so as to allow a plurality of first screws 505d to pass therethrough and lock the first sheet body 505 and the first base body 501.
The second sheet body 506 has a ring shape. A circular second through hole 506a is formed at a center of the second sheet body 506 so as to allow the second rotating member 504 to pass therethrough. The second rotating member 504 passes through the second base body 502 and the second sheet body 506 and protrudes from the second sheet body 506 for engaging with the target handle 82. Further, a second stop arm 506b of a bent shape extends from an edge of the second sheet body 506 and abuts against the driving member 404 of the third acting assembly 40. Furthermore, a plurality of circular second openings 506c are formed on a ring body of the second sheet body 506 so as to allow a plurality of second screws 506d to pass therethrough and lock the second sheet body 506 and the second base body 502.
Further, the operating assembly 50 has a plurality of sliding blocks 507, 507′ engaging with the first sliding slot 501c and the second sliding slot 502c. A circular arc cap shaped pressing portion 507a, 507a′ is formed at one end of the sliding block 507, 507′ and a blocking portion 507b, 507b′ is formed at the other end of the sliding block 507, 507′. Furthermore, a middle portion 507d, 507d′ narrower than the pressing portion 507a, 507a′ and the blocking portion 507b, 507b′ is formed between the two ends of the sliding block 507, 507′, and a through hole 507c, 507c′ is formed at a center of the middle portion 507d, 507d′. For example, an elastic element 508, 508′ such as a compression spring is disposed around the middle portion 507d, 507d′ of the sliding block 507, 507′. The outer diameter of the elastic element 508, 508′ is greater than the hole diameter of the first sliding slot 501c and the second sliding slot 502c. As such, the elastic elements 508, 508′ are clamped outside the first sliding slot 501c and the second sliding slot 502c, and the first position limiting portion 501d and the second position limiting portion 502d engage with the middle portions 507d, 507d′ of the sliding blocks 507, 507′ so as to prevent the sliding blocks 507, 507′ from falling off. For example, the elastic elements 508, 508′ can generate an outward pushing force on the sliding blocks 507, 507′.
In addition, the door lock device 2 can be configured with a first fastening member 51 and a second fastening member 52 such as screws based on requirements. The first fastening member 51 and the second fastening member 52 can be passed through the first opening 505c, the second opening 506c and the through holes 507c, 507c′ of the middle portions 507d, 507d′ of the sliding blocks 507, 507′ so as to fasten the sliding blocks 507, 507′ between the first sheet body 505 and the first base body 501 and between the second sheet body 506 and the second base body 502, respectively.
During the use of the door lock device 2, the target key 80 (or the indoor knob) can drive the lock head 201 and the security bolt 301 to extend or retract relative to the receiving space S, thereby locking or unlocking the door lock device 2. Also, through the operating assembly 50, the target handle 81, 82 can drive the lock tongue 401 to extend or retract relative to the receiving space S, thereby locking or unlocking the door lock device 2.
In an embodiment, the second operating mechanism 5b of the operating assembly 50 (i.e., the second sheet body 506, the second rotating member 504 and the second base body 502) is described.
Referring to
After the door lock device 2 is mounted onto the door body 9 (as shown in
Further, if the user presses the button 24 toward a position corresponding to the first acting plate 25 (a pressing force P2 of
Furthermore, referring to
It should be understood that the method of actuating the lock head 201, the security bolt 301 and the lock tongue 401 by the target key 80 (or the indoor knob) is well known in the art (as shown in
Therefore, based on the interlocking state of the second operating mechanism 5b of the operating assembly 50, the target handle 82 corresponding to the second operating mechanism 5b can be placed indoors so as to facilitate the user (or the indoor person) to go into or out of the door.
On the other hand, if the second fastening member 52 is removed during the assembling process of the door lock device 2, the target handle 82 in use cannot drive the lock tongue 401. Only the target key 80 can drive the lock head 201 and the security bolt 301 to extend or retract. Therefore, the door lock device 2 presents another locking state.
Referring to
After the door lock device 2 is mounted onto the door body 9 (as shown in
Thereafter, when the user closes and locks the door body 9 (as shown in
Therefore, based on the idle state of the second operating mechanism 5b of the operating assembly 50, the target handle 82 corresponding to the second operating mechanism 5b can be placed outdoors. As such, when the door lock device 2 is in a locking state (the lock head 201, the security bolt 301 and the lock tongue 401 extend out of the receiving space S), if the target handle 82 is impacted by an external object (or forced to rotate by an unscrupulous person), the operating assembly 50 will not be damaged since the target handle 82 is in the idle state. Even if the target handle 82 is damaged, it is only necessary to replace the target handle 82 (the repair cost is quite low), and the operation of the door lock device 2 is still normal.
It should be understood that the user can press the button 24 so as to cause the target handle 82 and the second operating mechanism 5b of the operating assembly 50 to enter into the interlocking state or the idle state.
On the other hand, since the first operating mechanism and the second operating mechanism act in the same manner, as shown in
Referring to
The electromagnetic valve 60 acts when being supplied with an electric current. For example, a guiding rod 601 extends outward to push one end of the rotating plate 29′, thus causing the other end of the rotating plate 29′ to go upward and push the sliding block 507, 507′.
The battery 61 provides an electric current into the electromagnetic valve 60 so as to drive the electromagnetic valve 60 to extend the guiding rod 601.
In an embodiment, the electric current output action of the battery 60 is controlled by the button 24. For example, the button 24 is an electrical switch, which connects the battery 61 and the electromagnetic valve 60 through wires 62. Therefore, by selecting the pressing direction of the button 24 to control the action of the electromagnetic valve 60, the guiding rod 601 of the electromagnetic valve 60 can be extended or retracted to control the rotation of the rotating plate 29′ to thereby push the sliding block 507.
Since the wires 62 can be arranged according to the requirement, the arranging position of the electromagnetic valve 60 and the battery 61 can be more flexible. Therefore, the first and second acting plates 25, 26, the rotating sheet 27 and the elastic sheet 28 can be replaced by the electromagnetic valve 60, the battery 61 and the wires 62 so as to improve the flexibility of arrangement of the regulating assembly 2b.
Referring to
In an embodiment, the rotating plate 79 is in the shape of a curved knife, which has a handle 790 corresponding to the first acting plate 25. In operation, the first acting plate 25 is interlocked with a blade 791 of the rotating plate 79. For example, the spring 22 is connected to the handle 790 of the rotating plate 79. The spring 22 applies an elastic force on the rotating plate 79 so as to cause the rotating plate 79 to rotate the blade 791 based on the pivot portion 29a. When the button 24 drives the first acting plate 25 to push the handle 790, the blade 791 of the rotating plate 79 moves away from the sliding block 507. On the other hand, when the button 24 drives the first acting plate 25 to move away from the handle 790, the blade 791 of the rotating plate 79 pushes the sliding block 507 through the elastic force of the spring 22.
Referring to
In use, the electromagnetic valve 60 senses an inductive magnetic card (not shown) and generates an electric current so as to extend a guiding rod 601 to push one end of the rotating plate 29′, thus causing the other end of the rotating plate 29′ to go upward and push the sliding block 507, 507′. On the other hand, after the electromagnetic valve 60 is turned off, the guiding rod 601 retracts to drive one end of the rotating plate 29′ to go up, thereby causing the sliding block 507, 507′ to push the other end of the rotating plate 29′.
Therefore, through the design of the door lock device 8 in the form of an electronic lock, the button 24, the first and second acting plates 25, 26, the rotating sheet 27 and the elastic sheet 28 are replaced by the electromagnetic valve 60 so as to increase the arrangement area of the receiving space S of the housing 2a, thereby improving the flexibility of arrangement of the components of the electronic lock.
According to the door lock device 2, 2′, 2″, 8 of the present disclosure, by removing the fastening member (the first or second fastening member 51, 52) of the operating mechanism corresponding to the outdoor handle, the target handle 81, 82 and the operating assembly 50 can enter into an interlocking state or an idle state according to the requirement. If the target handle 81, 82 serves as an outdoor handle, the user can regulate the operating assembly 50 and the outdoor handle into the idle state through the button 24 or the inductive magnetic card (not shown). As such, the outdoor handle cannot operate the lock tongue 401 when the door lock device 2, 2′, 2″, 8 is in a locking state. Therefore, if the outdoor handle is forced to rotate, the operating assembly 50 is prevented from being damaged.
Further, by using the security post 403b as a fireproof mechanism, the door lock device 2, 2′, 2″, 8 can meet the requirements of fire doors and therefore can be mounted on a fire door.
The above-described descriptions of the detailed embodiments are to illustrate the preferred implementation according to the present disclosure, and it is not to limit the scope of the present disclosure. Accordingly, all modifications and variations completed by those with ordinary skill in the art should fall within the scope of the present disclosure defined by the appended claims.
