Description

Technical Field

[0001] This utility model relates to the field of folding door technology, and in particular to a folding door with a multi-lock structure. Background Technology

[0002] In the field of architectural doors and windows, folding doors, due to their unique opening mechanism, space-saving design, and ability to provide a large passageway, are widely used in various locations such as shopping malls, hotels, conference rooms, and balconies. Existing folding doors typically employ a relatively simple design to achieve the locking function, namely, installing a locking mechanism and handle only on the first door. Operating this locking mechanism locks the entire folding door; pushing the handle allows the folding door to slide open or close.

[0003] However, this traditional folding door design has revealed many problems in actual use. When a folding door consists of two or more panels, the middle panels are not fixed in place. When affected by external factors, such as airflow generated by people walking, vibrations from the surrounding environment, or even slight human touch, these middle panels will wobble. This wobbling not only generates noise, affecting the quietness and comfort of the environment, but may also damage the folding door itself, reducing its lifespan. Utility Model Content

[0004] The purpose of this utility model is to disclose a folding door with a multi-lock structure, which effectively solves the technical problem of the middle door wobbling in existing folding doors.

[0005] To achieve the above objectives, this utility model discloses a multi-lock folding door, comprising: at least two folding door bodies connected in sequence by rotation; a locking mechanism, wherein the locking mechanism is disposed on each of the folding door bodies, the locking mechanism including a lock groove device and a lock, one of which is mounted on a track or door frame, and the other is mounted on the folding door body; when unlocking, the lock disengages from the lock groove device, and when locking, the lock engages with the lock groove device; and a handle device, wherein the handle device is disposed on each of the folding door bodies, and the handle device on each folding door body is linked to the locking mechanism on the same folding door body. Each handle device includes a first unlocking mechanism and a second unlocking mechanism that can independently control the unlocking of the locking mechanism. The first unlocking mechanism is provided with an unlocking reset member for automatically locking the locking mechanism after unlocking, and the second unlocking mechanism has a first locking position for locking the locking mechanism and a second locking position for unlocking the locking mechanism.

[0006] By adopting the above solution, when locked, all door panels are rigidly connected to the lock and lock slot device to form an integral structure, completely eliminating the space for free swaying of the middle door panels. The first unlocking mechanism automatically returns to its locking position after unlocking through the unlocking reset component, ensuring that the door panels are quickly locked after a brief opening, avoiding prolonged unsecured states due to user negligence. The second unlocking mechanism achieves long-term unlocking / locking through a locking position switching mechanism. When actively switching to the second locking position, the locking mechanism remains unlocked, allowing all door panels to slide freely. Switching to the first locking position restores all door panels to the locked state. This design meets the needs of both partially open and fully open scenarios, while ensuring that all door panels are locked after closing.

[0007] Furthermore, the handle device is embedded in one side of the folding door body or is disposed through the thickness direction of the folding door body.

[0008] By adopting the above solution, when the handle device is embedded in one side of the folding door body, its structure is integrated with the door body, avoiding the exposed handle from collision; if the handle is installed through the door body thickness, its two ends are fixed to the internal structure of the door body by bolts or buckles, forming a two-way force support, which can effectively disperse the torque when the door is opened / closed, prevent the door body from deforming due to the force on one side of the handle, and provide an optional solution for installing door handles on both sides.

[0009] Furthermore, it also includes a handle frame having a receiving groove, and the handle device is installed within the handle frame.

[0010] By adopting the above solution, the handle frame can be pre-assembled in the factory as an independent module, while providing a stable installation space for the handle device. The overall modular design makes replacement or maintenance more convenient.

[0011] Furthermore, it also includes a sliding member that slides longitudinally relative to the folding door body to synchronously drive the bolt of the lock. A reset member is provided between the sliding member and the folding door body to reset the sliding member to the bolt extended state so that the bolt can lock with the lock groove. The first unlocking mechanism and the second unlocking mechanism simultaneously drive the sliding member to abut against the bolt when the bolt is in the extended state.

[0012] By adopting the above solution, the sliding component moves longitudinally along the folding door body, and its movement trajectory is consistent with the height direction of the door body, which can simultaneously drive the extension and retraction of the latch.

[0013] Furthermore, a transmission component is provided between the sliding member and the locking tongue, and the transmission component moves synchronously with the locking tongue and the sliding member.

[0014] By adopting the above solution, the transmission component can solve the problem of the long distance between the sliding component and the locking tongue.

[0015] Furthermore, the slider is equipped with a first trigger and a second trigger that move synchronously with it. When the slider and the latch are in a locked state, the first unlocking mechanism abuts against the upper side of the first trigger, and the second unlocking mechanism abuts against the upper side of the second trigger.

[0016] By adopting the above scheme, the first trigger and the second trigger independently control the first unlocking mechanism and the second unlocking mechanism, respectively, so that both can perform unlocking operations, and the upper position facilitates the downward movement of the locking tongue to retract and unlock.

[0017] Furthermore, the handle device has a recessed mounting groove, the first unlocking mechanism is hinged in the mounting groove, and the first unlocking mechanism is provided with a first actuating member capable of driving the first trigger member to move downward.

[0018] By adopting the above solution, the recessed mounting groove embeds the first unlocking mechanism inside the handle, greatly reducing the thickness of the door. At the same time, the handle can be protruded from the mounting groove by hinge rotation, realizing a structure that is easy to grip and facilitates opening / closing the folding door.

[0019] Furthermore, the second unlocking mechanism slides longitudinally within the mounting groove, and the first and second locking positions are located on the sliding path of the second unlocking mechanism. The second unlocking mechanism is provided with a second toggle member capable of driving the second trigger member to move downward.

[0020] By adopting the above solution, the second unlocking mechanism is also hidden in the recessed mounting groove, avoiding the risk of the second unlocking component being accidentally activated, while ensuring that the door thickness does not increase.

[0021] Furthermore, the handle devices of each of the folding door bodies are installed in the same position and in the same number.

[0022] By adopting the above solution, the operational consistency, safety, and economy of the folding door system are enhanced, while the overall aesthetics are improved.

[0023] Furthermore, each folding door body has two handle devices, located on both sides of the folding door body, and the two handle devices synchronously drive the same locking mechanism.

[0024] The above solution is suitable for folding door scenarios with high-frequency use and two-way passage.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional folding doors only have a locking mechanism on the first door, and the middle doors are connected by hinges, which leaves room for free swaying. This application sets a locking mechanism on each door body and locks all the doors into a whole structure through the rigid connection between the lock and the lock groove device, which completely eliminates the swaying space. The swaying of the middle doors will cause the hinges, tracks and other components to loosen or deform due to repeated impacts. The multi-lock structure reduces the stress on the components through rigid locking and improves the service life of the hinges. 2. The first unlocking mechanism automatically returns to its locking position after unlocking via an unlocking reset component. After a user briefly opens the door, it automatically locks without manual operation, preventing the door from remaining unsecured for extended periods due to negligence and improving security. The second unlocking mechanism allows for prolonged unlocking / locking by switching between a first locking position and a second unlocking position. Switching to the second locking position keeps all door panels unlocked, allowing for free sliding to open and close. Switching to the first locking position restores all door panels to the locked state, ensuring overall locking after closing and preventing accidental opening due to wind pressure or human contact. 3. When there are three or more folding doors, the multi-lock structure can selectively unlock two doors to achieve a half-open, half-closed effect, allowing normal pedestrian passage and avoiding unnecessary space opening. For example, in fitting room areas of shopping malls or small meeting rooms, this flexible opening method can better meet the space needs of different scenarios, improving space utilization. When a large number of people or goods need to pass through, all folding doors can be unlocked and opened to provide a larger passage opening, without being restricted by the door opening method, fully leveraging the advantages of folding doors in saving space and providing a large passage opening.

[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0035] Please refer to Embodiment 1 of this utility model. Figures 1 to 6 As shown, a multi-lock folding door of this embodiment is provided, consisting of at least two folding door bodies 1 connected in sequence by rotation. Each folding door body 1 is equipped with an independent locking mechanism 2 and a handle device 3. The locking mechanism 2 includes a lock groove device 21 and a lock 22. One of the lock groove device 21 and the lock 22 is mounted on a track or door frame, and the other is mounted on the folding door body 1. When unlocking, the lock 22 disengages from the lock groove device 21. When locking, the lock 22 locks with the lock groove device 21. All door panels form an integral structure through the rigid connection between the lock 22 and the lock groove device 21, completely eliminating the free swaying space of the middle door panels. The handle device 3 on each folding door body 1 is linked to the locking mechanism 2 on the same folding door body 1. Each of the three components includes a first unlocking mechanism 31 and a second unlocking mechanism 32 that can be independently controlled to unlock the locking mechanism 2. The first unlocking mechanism 31 is equipped with an unlocking reset component 311 for automatically locking the locking mechanism 2 after unlocking. The first unlocking mechanism 31 achieves automatic locking after unlocking through the unlocking reset component 311, ensuring that the door leaves quickly lock after a brief opening and preventing the door leaves from being in an unsecured state for a long time due to user negligence. The second unlocking mechanism 32 has a first locking position 8 for locking the locking mechanism 2 and a second locking position 9 for unlocking the locking mechanism 2. The second unlocking mechanism 32 achieves long-term unlocking / locking by switching between locking positions. When actively switching to the second locking position 9, the locking mechanism 2 remains in the unlocked state, and all door leaves can slide freely. When switching to the first locking position 8, all door leaves return to the locked state. This design meets the needs of both partially open and fully open scenarios, while ensuring that all door leaves are locked after closing.

[0036] It should be noted that the locking mechanism 32 between the second unlocking mechanism 32 and the first locking position 8 and the second locking position 9 includes, but is not limited to, a steel ball positioning structure and a protrusion groove structure.

[0037] The following section explains its working principle and implementation details in conjunction with its specific structure.

[0038] The folding door body 11 adopts a structure of at least two door panels that are connected in sequence by rotation. The material of the door panels can be selected according to the actual use scenario and needs. The door panels are flexibly rotated by hinges or other rotating connectors to ensure that the folding door can be folded and unfolded smoothly. Taking a four-panel folding door as an example, the four doors are connected in sequence by hinges to form a door structure that can be moved as a whole and folded for storage. The lock groove device 21 is fixed to the track or the top of the door frame opposite each door panel. The lock 22 is installed on the top of each door body and includes a retractable lock tongue. When the lock tongue is extended, it is inserted into the lock groove device 21 to achieve rigid locking; when it is retracted, it is disengaged from the lock groove, allowing the door panel to slide. The locking mechanism 2 only needs to be able to perform the above basic operations. Preferably, the locking mechanism 2 can be the folding door magnetic lock mechanism in patent CN222924271U, which will not be described in detail here.

[0039] Preferably, in this embodiment 1, a sliding member 6 is also provided in the side frame of the folding door body 1, which can slide longitudinally relative to the folding door body 1, for synchronously driving the lock tongue of the lock 22 to move. In order to avoid the problem of difficult operation due to the large distance between the two, a transmission member 7 is also provided between the sliding member 6 and the lock tongue. The transmission member 7 moves synchronously with the lock tongue and the sliding member 6. The transmission member 7 can solve the problem of the large distance between the sliding member 6 and the lock tongue. Preferably, the transmission component 7 adopts a synchronous pull rope or pull rod mechanism to drive the locking mechanism 2 to complete the unlocking operation. In order to avoid the absence of a reset structure in the internal locking tongue of some locking structures, a reset component 5 is provided between the sliding component 6 and the folding door body 1 in some embodiments. The reset component 5 is used to reset the sliding component 6 to the state of the extended locking tongue so that the locking tongue can lock with the lock groove. The first unlocking mechanism 31 and the second unlocking mechanism 32 simultaneously drive the sliding component 6 in the state of the extended locking tongue to abut. The sliding component 6 moves longitudinally along the folding door body 1, and its movement trajectory is consistent with the height direction of the door body, which can simultaneously drive the extension and retraction of the locking tongue.

[0040] The sliding member 6 is also equipped with a first trigger member 61 and a second trigger member 62 that move synchronously with it. Optionally, the first trigger member 61 and the second trigger member 62 are connected to the sliding member 6 by means of screws, snaps, or integral connections, including but not limited to screw connections, snap connections, or integral connections. Preferably, the handle device 3 adopts a concave design and has a concave mounting groove 33. In this embodiment 1, the first unlocking mechanism 31 is hinged in the mounting groove 33. The first unlocking mechanism 31 is provided with a first actuating member 312 that can drive the first trigger member 61 to move downward. The concave mounting groove 33 embeds the first unlocking mechanism 31 into the handle, greatly reducing the thickness of the door body. At the same time, the handle can protrude from the mounting groove 33 by hinged rotation, realizing a structure that is easy to grip and facilitates opening / closing the folding door. Since it is necessary to provide rotation space for the first actuating member 312, an opening is provided in the mounting groove 33 to avoid the first actuating member 312. The second unlocking mechanism 32 slides longitudinally within the mounting groove 33 and does not interfere with the first unlocking mechanism 31. The second unlocking mechanism 32 is also hidden within the recessed mounting groove 33, avoiding the risk of accidental activation of the second unlocking component and ensuring that the door thickness does not increase. The first stop 8 and the second stop 9 are located on the sliding path of the second unlocking mechanism 32, with the first stop 8 directly above the second stop 9. The second unlocking mechanism 32 is equipped with a second actuating component 321 capable of driving the second trigger 62 downwards. The second actuating component 321 also requires sliding space; therefore, the mounting groove 33 has an opening to avoid the second actuating component 321. When the sliding component 6 and the latch are in the locked state, the first unlocking mechanism 31 abuts against the upper side of the first trigger 61, and the second unlocking mechanism 32 abuts against the upper side of the second trigger 62. When the user pulls out the first unlocking mechanism 31 from the bottom, the first unlocking mechanism 31 rotates relative to the mounting groove 33, causing the first actuating member 312 located above the first unlocking mechanism 31 to rotate downward, driving the first trigger member 61 to move downward. The transmission member 7 and the sliding member 6 move downward synchronously, causing the latch to retract and unlock. When the first unlocking mechanism 31 is released, it is automatically reset to the mounting groove 33 by the reset force of the unlocking reset member 311. At the same time, the sliding member 6 is reset by the reset force of the reset member 5, causing the latch to retract and extend. When the user drives the second unlocking mechanism 32 to slide from the first stop 8 to the second stop 9, the second actuating member 321 of the second unlocking mechanism 32 drives the second trigger member 62 to move downward. The transmission member 7 and the sliding member 6 move downward synchronously, causing the latch to retract and unlock. When the second unlocking mechanism 32 is engaged at the second stop 9, the latch remains in a retracted state. At this time, the first unlocking mechanism 31 being driven will not affect any changes in the sliding member 6 and the latch, and can only be used as a handle for easy opening and closing of the door.When the user drives the second unlocking mechanism 32 to slide from the second stop position 9 to the first stop position 8, the sliding member 6 is simultaneously subjected to the reset force of the reset member 5, causing the lock tongue to gradually extend and reset. When the second unlocking mechanism 32 is engaged with the first stop position 8, the first unlocking mechanism 31 can resume its unlocking function.

[0041] It should be noted that the handle device 3 is embedded in one side of the folding door body 1 or extends through the thickness of the folding door body 1. When the handle device 3 is embedded in one side of the folding door body 1, its structure is integrated with the door body, avoiding the exposed handle from impact. If the handle extends through the thickness of the door body, its two ends are fixed to the internal structure of the door body by bolts or clips, forming a two-way force support, which can effectively distribute the torque when the door is opened / closed, prevent the door body from deforming due to the force on one side of the handle, and provide an optional solution for installing door handles on both sides. In actual use, if a single-sided opening is used, the former installation method is selected; when a double-sided opening is used, the latter installation method can be selected.

[0042] In some embodiments, to enhance the modular design of the handle device 3, a handle frame 4 is also included. The handle frame 4 has a receiving slot 41, and the handle device 3 is installed within the handle frame 4. One handle device 3 can be installed within one handle frame 4 for single-sided door opening, and two handle devices 3 can be installed within one handle frame 4 for double-sided door opening. As an independent module, the handle frame 4 can be prefabricated in the factory, providing a stable installation space for the handle device 3. The overall modular design makes replacement or maintenance more convenient.

[0043] It should be noted that in this embodiment 1, the installation position and number of handle devices 3 are consistent for each folding door body 1. This arrangement enhances the operational consistency, safety, and economy of the folding door system, while also improving the overall aesthetics.

[0044] In this embodiment 1, each folding door body 1 has two handle devices 3, which are located on both sides of the folding door body 1 respectively, and the two handle devices 3 synchronously drive the same locking mechanism 2, which can be applied to folding door scenarios with high frequency of use and two-way passage.

[0045] Preferably, in some embodiments, the projected area of ​​the mounting groove 33 on the folding door body 1 is greater than the sum of the projected areas of the first unlocking mechanism 31 and the second unlocking mechanism 32 on the folding door body 1, so that the mounting groove 33 has a reserved first operating gap. The reserved operating gap provides sufficient space for fingers to reach into the mounting groove 33 to touch and operate, making the operation process smoother and less strenuous, while avoiding the risk of fingers being pinched.

[0046] During unlocking, the user selects either the first unlocking mechanism 31 or the second unlocking mechanism 32 to unlock a single door, as needed. The user can then push or pull the unlocked door to open or close it. To unlock multiple doors, the above operation can be repeated. Simultaneously, a folding door can be partially opened and partially closed.

[0047] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
