Description

Technical Field

[0001] This utility model relates to the technical field of door and window accessories, and in particular to a handle and a folding door having the handle. Background Technology

[0002] In daily life and various building facilities, door handles, as an important component of doors, directly affect the ease of use and security of doors through their function and design. Currently, most existing door handles have an automatic reset locking mechanism. While this design achieves basic locking functionality in many scenarios, it has revealed a series of problems during actual use.

[0003] Specifically, because the locking mechanism extends naturally in its natural locking state, this characteristic creates numerous obstacles during door opening and closing. Taking sliding doors as an example, to achieve the locking effect, handles are usually installed on one or both sides of the sliding door. Unlocking is achieved by turning or operating the handle, and the locking mechanism automatically resets once the handle is released. However, the latch of a sliding door is generally located on the edge of the door. During sliding, the naturally retracting latch is prone to colliding with the door frame or track, potentially damaging the handle and related components, generating noise, and affecting the user experience.

[0004] Furthermore, when sliding doors have multiple locking mechanisms, multiple matching slots are provided on the corresponding tracks to cooperate with these mechanisms. Since the locking mechanisms are in their extended position in their natural state, they engage with each slot sequentially during the opening of the sliding door. This results in the need to operate the handle multiple times to fully open the door each time, making the opening process cumbersome and complex, reducing efficiency, especially in places where doors need to be opened and closed frequently, causing significant inconvenience to users. Utility Model Content

[0005] The purpose of this utility model is to disclose a handle that effectively solves the problems of bumps and knocks during the opening and closing of existing door handles, as well as the cumbersome and complicated opening process.

[0006] To achieve the above objectives, this utility model discloses a handle, comprising: a sliding member having a locking position for triggering a lock to lock and an unlocking position for triggering a lock to unlock; and a drive module comprising a drive housing having an assembly cavity, wherein a first operating member and a second operating member are disposed at intervals within the assembly cavity, the first operating member being hinged to the assembly cavity, a first triggering member for transmission being disposed between the first operating member and the sliding member, and the second operating member being slidably disposed within the assembly cavity, a second triggering member for transmission being disposed between the second operating member and the sliding member. A trigger element; an elastic element for resetting the first trigger element is provided in the assembly cavity; when the sliding element is in the locked position, it is drivenly connected to the reset first trigger element; when the sliding element is in the unlocked position, it is disengaged from the reset first trigger element; a locking element with a first locking position and a second locking position is provided in the assembly cavity; when the second trigger element is in the first locking position, the sliding element is in the locked position, and the reset first trigger element is drivenly connected to the sliding element; when the second trigger element is in the second locking position, the sliding element is in the unlocked position, and at this time the reset first trigger element disengages from the sliding element.

[0007] By adopting the above solution, the first operating component enables the automatic reset locking and unlocking functions of the existing handle. The second operating component, acting as the lock's control component, ensures the lock remains unlocked for an extended period when the second trigger is in the second stop position. The lock will not extend any structure, preventing collisions between the lock and the door frame, lock slot, or other components during door opening and closing. This effectively protects the door handle and related components, reduces noise, and improves the safety and smoothness of door opening and closing. When the lock is in the unlocked state for an extended period, the first operating component no longer functions as a locking / unlocking device and functions solely as a regular handle for pushing and pulling the door. Therefore, when a sliding door has multiple locks and corresponding lock slots, the locks remain unlocked, preventing sequential locking with each slot during opening. Users can open the door smoothly with a single operation, greatly simplifying the opening process, improving efficiency, and meeting users' needs for convenient door opening and closing in various scenarios. When the second operating element is activated again, the lock automatically resets and locks, the first operating element resumes its operating function, and the device returns to normal operation.

[0008] Furthermore, it also includes a limiting and fixing component, which is used to fix it to the door body. A spring component is provided between the sliding component and the limiting and fixing component, which is used to provide elastic force for the sliding component to move and reset from the unlocked position to the locked position.

[0009] By adopting the above solution, the slider can automatically return to the locked position under the action of elasticity after unlocking, eliminating the need for users to perform additional reset operations, greatly simplifying the usage process and improving the convenience of use.

[0010] Furthermore, the slider is provided with a first contact member and a second contact member at intervals, the first contact member drivingly abutting against the first trigger member, and the second contact member drivingly abutting against the second trigger member.

[0011] By adopting the above scheme, the first trigger and the second trigger can drive the sliding member to move in opposite directions, thus having an independent unlocking function.

[0012] Furthermore, the first trigger is disposed on the upper side of the first contact, and the second trigger is disposed on the upper side of the second contact. When the slider is in the locked position, the first trigger abuts against the first contact, and the second trigger abuts against the second contact.

[0013] By adopting the above scheme, the contacting parts can maintain contact when locked. When unlocking is required, either the first trigger or the second trigger can be slid to unlock. At the same time, the trigger is located on the upper side, so that after one trigger is unlocked, the operation of the other trigger will be invalid, and repeated unlocking will not occur.

[0014] Furthermore, it also includes a handle frame, the interior of which is hollow to form a receiving cavity, and the drive housing is partially embedded in the receiving cavity.

[0015] By adopting the above solution, the drive housing is partially embedded in the receiving cavity of the handle frame, avoiding the drive housing occupying extra space outside the handle. The hollow receiving cavity of the handle frame provides a reasonable placement space for the drive housing, making the layout of the various components inside the door lock more orderly. At the same time, it provides a fixed limiting effect, making the installation more stable, reducing the clutter of the internal space, and improving the space utilization rate.

[0016] Furthermore, there are two drive modules, which are respectively embedded on opposite sides of the receiving cavity.

[0017] By adopting the above solution and setting up two drive modules, in some two-way doors, such as hotel room doors and office doors, the handles on both sides, which have the same function, allow users to easily open and close the door from either side when people enter or leave the room from different directions. This ensures that both identical drive modules can operate the lock body.

[0018] Further, the first operating element includes: a first reset section, wherein the elastic element is disposed between the first reset section and the bottom wall of the assembly cavity; a second hinge section, wherein the second hinge section is hinged to both sides of the assembly cavity via a hinge rod, and the first trigger element is assembled to the second hinge section; and a third operating section, wherein the length of the third operating section is greater than or equal to the length of the first reset section.

[0019] By adopting the above scheme, the elastic component can accurately and smoothly push the first operating component back to its initial position using its own elastic potential energy, ensuring that it can be restored to the standard state after each operation. At the same time, it can reset the first operating component into the assembly cavity, so that it will not protrude from the door body, improving aesthetics and reducing the possibility of damage.

[0020] Further, the second operating member includes: a first actuating member, which slides relative to the assembly cavity and has a first actuating block; and a second locking member, which is fixedly connected to the first actuating member and has a locking block that elastically engages with the first locking position and the second locking position.

[0021] By adopting the above solution, the first actuating component can slide flexibly within a specific space. When the user applies external force to the second operating component, the first actuating component can precisely trigger unlocking, locking, and other functions through the first actuating block. Simultaneously, the first actuating component can be concealed within the assembly cavity, preventing bumps and other issues. The locking block can elastically engage with the first or second locking position, fixing the first actuating component in that position, preventing accidental changes in the door handle's state under non-human operation, and improving the door's safety and stability.

[0022] Furthermore, the second locking member has a hollowed-out portion in the center, so that the two sides of the second locking member form a first arm and a second arm with deformation capability. The locking blocks are respectively disposed on the opposite outer sides of the first arm and the second arm, and an elastic support member is disposed between the first arm and the second arm.

[0023] By adopting the above solution, the hollowed-out design cleverly utilizes the internal space of the second locking component, reducing material usage while ensuring structural strength, making the entire locking component lighter. Simultaneously, the hollowed-out portion grants the first and second arms independent deformation capabilities, forming a reliable locking connection. The elastic support component provides additional elastic support force to the first and second arms, enabling the locking block to generate greater clamping force when engaging with the first and second locking positions. Furthermore, the elastic deformation range and flexibility of the first and second arms are further improved, increasing the number of elastic deformations and extending service life.

[0024] A folding door includes a plurality of door leaf bodies that are hinged sequentially, wherein at least one of the door leaf bodies is provided with a handle, and each door leaf body with a handle is provided with a locking element for locking with a track above or below the door leaf body.

[0025] By adopting the above solution, when the door is closed and locked, the door body is tightly connected to the track and cannot be easily pushed or opened, effectively preventing illegal intrusion and accidental opening. Multiple lock bodies can improve the connection stability of each door body and prevent shaking. During the opening process, all lock bodies can be unlocked by moving each second operating component, improving the smoothness of opening the door.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Existing door handles have a locking mechanism that extends and locks in its natural state. During the sliding of the door, the latch is prone to colliding with the door frame or track, causing damage to the door handle and related components. However, the handle in this invention, when the second operating element is activated to place the second trigger element in the second locking position, can control the lock to remain in the unlocked state for an extended period, preventing the lock from extending any part. This avoids collisions between the lock and the door frame, lock groove, etc., during door opening and closing, effectively protecting the door handle and related components and extending the service life of the equipment. 2. Collisions between the lock and door frame, lock groove, and other components can not only damage these parts but also generate unpleasant noise, affecting the user experience. This handle design prevents such collisions, thereby reducing noise and creating a quieter, more comfortable user environment. 3. When a sliding door has multiple locking mechanisms, existing door handles, during the opening process, require multiple handle operations to fully open the door because the locking mechanism is in its extended state. This process is cumbersome and reduces efficiency. However, with this new design, when the locking mechanism is in the unlocked state for an extended period, the first operating component functions as a regular handle for pushing and pulling the door, eliminating the need for sequential locking with each lock slot. Users can open the door smoothly with a single operation, significantly simplifying the opening process. 4. The first operating component enables the automatic lock / unlock and automatic reset functions of the existing handle. The second operating component, acting as the lock's control component, allows switching between prolonged unlocking and automatic lock / unlocking. When the lock is unlocked for an extended period, the first operating component functions as a regular handle. Moving the second operating component again automatically locks the lock, and the first operating component resumes its operational function. This switching design allows the handle to adapt to different usage scenarios and needs, improving flexibility. Users can control the lock's state with a simple movement of the second operating component; the operation is intuitive and requires no complex steps or specialized knowledge. When locking the door, moving the second operating component again automatically locks the door, and the first operating component resumes its operational function, ensuring the door remains securely locked when closed, preventing unauthorized entry and protecting the user's personal and property safety.

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] Please refer to Embodiment 1 of this utility model. Figures 1 to 6 As shown, a handle is provided, including a slider 2 and a drive module 3. It should be noted that for doors that only require opening from one side, only one drive module 3 is needed. When opening from both sides is required, two drive modules 3 are used. This embodiment 1 uses two drive modules 3 as an example for detailed description. The drive module 3 is embedded within the door leaf body 5 of the folding door. Preferably, the door leaf body 5 can be equipped with a handle frame 1 for fixing and limiting the drive module 3. The handle frame 1 has a receiving cavity 11, and the two drive modules 3 are respectively embedded on opposite sides of the receiving cavity 11. It should be noted that the handle is not limited to being mounted on a door or window.

[0037] Specifically, the handle frame 1 is made of high-strength plastic or metal, with a hollow interior forming a receiving cavity 11, which provides installation space for the drive module 3. The surface of the handle frame 1 is smoothed, and its dimensions are rationally designed according to the actual application scenario and the size of the door to ensure coordination with the overall style of the door. The sliding member 2 is made of wear-resistant plastic or metal and can slide smoothly between the handle frame 1 and the door frame. It has a clearly defined locking position for triggering the lock and an unlocking position for triggering the lock. In this embodiment 1, the handle is applied inside a folding door, and the lock is located at the top or bottom of the folding door. The sliding member 2 is used to connect to the pull rod device, which can drive the bolt located at the top or bottom of the door to move, realizing the retraction and extension functions. To ensure that the bolt has the function of automatic reset extension, refer to... Figure 5As shown, a limiting and fixing component 3222 is provided on the side wall of the door body. The limiting and fixing component is provided with a first abutting block 61. A rectangular hole 23 is provided in the center of the sliding component 2. A second abutting block 231 is installed in the rectangular hole 23. A spring component 7 is provided between the first abutting block 61 and the second abutting block 231 to reset and extend the bolt, so that the bolt of the lock body always remains in the extended state in its natural state. The spring component 7 is used to provide elastic force for the sliding component 2 to move and reset from the unlocked position to the locked position. In other embodiments, the specific connection structure of the sliding component 2 is not limited, as long as the resetting and extension effect of the bolt can be achieved.

[0038] In this embodiment 1, the drive module 3 includes a drive housing 31, which is at least partially embedded in the receiving cavity 11. The assembly cavity 311 is provided with a first operating member 32, a second operating member 33, a first trigger member 34, a second trigger member 35, an elastic member 8, and a locking member 4. The sliding member 2 has a first contact member 21 and a second contact member 22 spaced apart on the side facing the handle frame 1. These two contact members respectively engage with the first trigger member 34 and the second trigger member 35 in the drive module 3 to transmit power. The first trigger member 34 is located above the first contact member 21, and the second trigger member 35 is located above the second contact member 22. When the sliding member 2 is in the locked position, the first trigger member 34 abuts against the first contact member 21, and the second trigger member 35 abuts against the second contact member 22.

[0039] Specifically, the first operating component 32 includes a first reset section 321, a second hinge section 322, and a third operating section 323. An elastic element 8, which is a spring, is provided between the first reset section 321 and the bottom wall of the first assembly cavity 311. This elastic element 8 can precisely and smoothly push the first operating component 32 back to its initial position using its own elastic potential energy, ensuring that it returns to its standard state after each operation. It also allows the first operating component 32 to be reset within the first assembly cavity 311, preventing it from protruding from the door body, improving aesthetics, and reducing the possibility of damage. The second hinge section 322 is hinged to both sides of the first assembly cavity 311 via hinge rods, and the first trigger element 34 is assembled to the second hinge section 322. The length of the third operating section 323 is greater than or equal to the length of the first reset section 321, facilitating user operation. During installation, an assembly position 3221 is provided on the side of the second hinge section 322 facing the first assembly cavity 311, and the first trigger element 34 is fixed to the assembly position 3221 by a fixing element 3222, such as a screw. The first assembly cavity 311 is provided with a first clearance hole 3111 corresponding to the first trigger member 34. The first trigger member 34 is provided with a first trigger block 341 passing through the first clearance hole 3111, so as to ensure that the first trigger member 34 can be accurately connected to the sliding member 2.

[0040] Specifically, the second operating component 33 includes a first actuating component 331 and a second locking component 332. The first actuating component 331 is slidably disposed between the locking plate 41 and the first drive housing 31, and has a first actuating block 3311 extending from the second clearance hole 411 into the first assembly cavity 311. When the user applies external force to the second operating component 33, the first actuating component 331 can precisely trigger unlocking, locking, and other functions through the first actuating block 3311. The second locking component 332 is fixedly connected to the first actuating component 331, and the second locking component 332 is provided with a locking block 3324 that elastically engages with the first locking position 44 and the second locking position 45.

[0041] To accommodate the flexible design, a hollow portion 3321 is provided in the center of the second locking member 332, so that a first arm 3322 and a second arm 3323 with deformation capability are formed on both sides of the second locking member 332. The locking blocks 3324 are respectively provided on the opposite outer sides of the first arm 3322 and the second arm 3323. This design reduces the amount of material used while ensuring structural strength, making the entire locking member lighter. At the same time, the first arm 3322 and the second arm 3323 have independent deformation capabilities due to the presence of the hollow portion 3321, forming a reliable locking connection.

[0042] In some embodiments, an elastic support member 3325 is provided between the first arm 3322 and the second arm 3323, providing additional elastic support force for the first arm 3322 and the second arm 3323, so that the locking block 3324 can generate a greater locking force when it engages with the first locking position 44 and the second locking position 45, while improving the elastic deformation range and flexibility of the first arm 3322 and the second arm 3323, and increasing the service life.

[0043] To accommodate the second locking member 332, in this embodiment 1, the locking member 4 includes a locking plate 41, a first protrusion 42, and a second protrusion 43. The locking plate 41 is assembled on the side of the first drive housing 31 facing the receiving cavity 11. A second clearance hole 411 is provided in the center of the locking plate 41. A third clearance hole 3112 is provided in the first assembly cavity 311 corresponding to the second clearance hole 411. The second trigger member 35 is provided with a second trigger block 351, which passes through the second clearance hole 411 and the third clearance hole 3112. The first protruding ridge 42 is located on the edge of the second clearance hole 411 on one side of the sliding direction of the second trigger 35, and the second protruding ridge 43 is located on the edge of the second clearance hole 411 on the other side of the sliding direction of the second trigger 35. The first locking position 44 and the second locking position 45 are located on opposite sides of the first protruding ridge 42 and the second protruding ridge 43. The locking plate 41 is assembled on the side of the first drive housing 31 facing the receiving cavity 11, making full use of the limited space inside the door handle and ensuring the compactness and aesthetics of the overall structure of the door handle. The second clearance hole 411 and the third clearance hole 3112 not only provide the necessary channels for the installation and sliding of the second trigger 35, but also ensure the accuracy of the installation position of the second trigger 35 through the positioning function of the two clearance holes, avoiding movement jamming or functional failure caused by installation deviation. The first protruding ridge 42 and the second protruding ridge 43 are respectively located on the edges of the second clearance holes 411 on both sides of the sliding direction of the second trigger 35, providing precise guidance for the sliding of the second trigger 35.

[0044] The specific operation process is as follows: The user operates the third operating segment 323 of the first operating member 32, causing the first operating member 32 to rotate around the hinge rod. Under normal circumstances, the third operating segment 323 fits against the assembly cavity 311 and is hidden within the assembly cavity 311. The first trigger 34 abuts against the first contact member 21 of the sliding member 2, the sliding member 2 is in the locked position, and the lock tongue is in the extended locked state. When the third operating segment 323 is lifted upward, the first operating member 32 drives the sliding member 2 to slide to the unlocked position through the first trigger 34, triggering the lock to unlock. After releasing the first operating member 32, the elastic member pushes the first operating member 32 back to the initial position. When it is necessary to maintain the unlocked state of the lock for a long time, the user moves the first actuating member 331 of the second operating member 33, causing the second trigger 35 to slide to the second stop position 45. Figure 1In this context, it can be understood as moving the first actuating element 331 downwards. At this time, the second trigger element 35 continuously abuts against the second contact element 22 of the sliding element 2, causing the bolt to retract into the lock body. Simultaneously, the reset first trigger element 34 disengages from the first contact element 21 of the sliding element 2, and the first operating element 32 no longer has the function of controlling locking and unlocking, but only serves as a regular handle for pushing and pulling the door. The lock remains in the unlocked state for a long time and will not extend any structure, avoiding collisions with the door frame, lock groove, and other components during the opening and closing of the door. When the second operating element 33 is moved again, in Figure 1 In this context, it can be understood that when the first toggle member 331 is moved upward, the second trigger member 35 slides to the first stop position 44, the lock automatically resets and locks, and the first operating member 32 resumes its operating function, thus enabling the door to automatically reset and lock and operate to unlock normally.

[0045] This utility model also relates to a folding door, comprising a plurality of door leaf bodies 5 hinged in sequence, wherein at least one of the door leaf bodies 5 is provided with a handle, and each door leaf body 5 provided with a handle is provided with a locking member, the locking member being used to lock with a track above or below the door leaf body 5.

[0046] This folding door is designed for various configurations. In one scenario, multiple door panels are equipped with the handle. The folding door comprises multiple sequentially hinged door panels 5, each with a handle as described above. Each door panel 5 with a handle is also equipped with a lock, which engages with the track above or below the door panel 5. This design ensures a consistent and aesthetically pleasing appearance, enhancing the overall aesthetics. Users can adjust the door's configuration by manipulating the second operating mechanism 33 on different door panels to lock or unlock a portion of the doors. For example, to fold only a portion of the doors, simply move the second operating mechanism 33 of the handle on the door panel to be folded to the second stop position 45, unlocking the locks on those doors while keeping the locks on the other doors locked. This allows for partial folding, meeting diverse usage needs. Since each door panel has a handle with these functions, users do not need to differentiate between the operation methods of different doors, improving ease of use. Meanwhile, when it is necessary to fully open or close the folding doors, the corresponding operation can be completed by operating the first operating component 32 or the second operating component 33 on each door leaf in sequence.

[0047] In one scenario, the handle is only installed on the end door leaf body 5. The folding door also includes multiple door leaf bodies 5 that are hinged sequentially, but the handle is only installed on the end door leaves, while the middle door leaves are equipped with door locks with a second operating element 33. This design is based on the consideration that the middle door leaves do not need to be operated when pushing or pulling, reducing the number of handles on the middle door leaves, lowering costs, and also making the appearance of the folding door more concise. When pushing or pulling the folding door, the user only needs to operate the handle on the end door leaf. Since the door lock of the middle door leaf is equipped with a second operating element 33, when it is necessary to unlock the middle door leaf, simply push down the first toggle block 3311 to unlock the middle door, and then pull the first operating element 32 of the end door leaf to smoothly push or pull the entire folding door.

[0048] 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.
