Description

Technical Field

[0001] This invention relates to the field of furniture technology, specifically a modular door system. Background Technology

[0002] In contemporary architectural and interior design, doors, as crucial components connecting and separating spaces, have always required careful consideration regarding their opening mechanisms and space requirements. Currently, the main door systems on the market include two basic types: sliding doors (or hinged doors) and swing doors (or hinged doors).

[0003] A common door system is the sliding door. Sliding doors typically use guide rails installed at the top or bottom of the door frame, allowing the door panels to slide laterally within these rails, thus opening or closing the space. The advantage of this opening method is that the door panels do not require additional space to be occupied outwards or inwards when opened, offering significant space-saving advantages for areas with limited space, such as narrow corridors or compact interior layouts. However, sliding doors also have inherent disadvantages. For example, in multi-door designs, because the door panels usually slide side-by-side, only one or one side of the door can often be opened at a time, thus limiting the full exposure of entrances or cabinet openings and the user's operating space. For situations requiring a large opening area for convenient access of goods or people, sliding doors are less flexible and convenient.

[0004] Another common door system is the hinged door. Hinged doors are mounted on the door frame via hinges, and the door leaf can open inwards or outwards around the hinge axis. The main advantage of hinged doors is that when the door leaf is fully open, it fully exposes the interior of the doorway or cabinet, providing an unobstructed, fully open effect that greatly facilitates the storage and retrieval of items and the movement of users. However, the disadvantages of hinged doors are equally prominent. When a hinged door is opened, its door leaf swings outwards or inwards, occupying additional space equal to the door leaf's own dimensions. This means that sufficient space must be reserved in the direction the door leaf opens; otherwise, it will hinder the door leaf from opening fully and may even collide with indoor furniture or walls. Therefore, in environments with limited indoor space, especially where the area in front of doorways or cabinets is not spacious, the use of hinged doors is significantly restricted, placing higher demands on the interior layout and furniture placement.

[0005] In conclusion, neither sliding doors nor hinged doors can find an optimal balance between space occupancy and opening size. Current technology lacks a door system that can flexibly choose its opening method based on actual needs, achieving full openness for easy access of large items while also allowing for space-saving opening when necessary. This forces users to compromise when choosing a door system, failing to fully meet diverse usage scenarios and the ever-increasing demands for space utilization efficiency. Therefore, further improvements are necessary. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a splicing door system that is more compact in structure, more aesthetically pleasing in appearance, and combines large opening with space saving and flexible opening methods.

[0007] The object of the present invention is achieved by the following means: a splicing door system, comprising a hinged door panel mounted on a door frame by a door hinge, wherein a first guide rail is fixedly mounted on the top of the hinged door panel; It also includes a second guide rail fixed to the top of the door frame, and a sliding door leaf is slidably installed in the second guide rail via a set of hanging wheels; It also includes a movable docking seat installed at the end of the first guide rail and a fixed docking seat installed at the end of the second guide rail. When the door is closed, the movable docking seat and the fixed docking seat dock together, so that the first guide rail and the second guide rail are connected. It also includes a locking block disposed in the movable docking seat. The locking block is linked to the linkage seat disposed on the door frame through a linkage mechanism. When the door is closed, the linkage seat drives the linkage mechanism to disengage the locking block from the first guide rail. When the door is opened, the linkage seat separates from the linkage mechanism, and the locking block is inserted into the first guide rail to restrict the sliding of the hanging wheel assembly. It also includes a lower guide rail set on the back of the sliding door leaf, and correspondingly, a lower guide block is set on the back of the sliding door leaf, which slides within the lower guide rail.

[0008] Furthermore: the movable docking seat is provided with a first fitting area at one end facing the first guide rail, and the movable docking seat is fitted and fixed to the end of the first guide rail through the first fitting area; The fixed docking seat is provided with a second fitting area at one end facing the second guide rail, and the fixed docking seat is fitted and fixed to the end of the second guide rail through the second fitting area.

[0009] Furthermore, a positioning buckle is provided on the end face of the movable docking seat facing the fixed docking seat, and correspondingly, an elastic groove is provided on the end face of the fixed docking seat facing the movable docking seat. When the door is closed, the positioning buckle is engaged in the elastic groove.

[0010] Furthermore: the fixed docking seat is provided with a guide groove, the elastic slider is slidably installed in the guide groove, a first spring is provided between the guide groove and the elastic slider, the first spring pushes the elastic slider to pop outward at all times, and the elastic groove is provided on the end face of the elastic slider.

[0011] Furthermore: the linkage mechanism includes a locking hole provided in the movable docking seat, a sliding block provided at the rear end of the locking block, and a plurality of guide posts provided on the sliding block; It also includes a transverse groove on the movable docking seat, in which a push block is slidably installed. The push block is provided with several inclined extrusion grooves. The guide post extends into the extrusion groove. When the push block slides along the transverse groove, it drives the locking block to slide back and forth in the locking hole through the extrusion groove.

[0012] Furthermore, a second spring is provided between the movable docking seat and the sliding block, and the second spring pushes the locking block to move in the direction of insertion into the first guide rail.

[0013] Furthermore, the linkage seat is equipped with a pressing wheel, and correspondingly, the push block is provided with a recessed positioning area at the position of the pressing wheel. When the door is closed, the pressing wheel is engaged in the positioning area, and the push block slides laterally along the transverse groove.

[0014] Furthermore: the lower guide rail has a "Z" shaped cross section, and its top and the sliding door leaf form a top opening guide area; the lower guide block includes a guide seat connected to the sliding door leaf, and the guide seat extends downward to provide a guide head, which extends into the guide area to slide.

[0015] Furthermore, the guide head is provided with an isolation block protruding towards the sliding door leaf, and the isolation block is in contact with the lower guide rail.

[0016] Furthermore, a lower support plate is provided extending forward from the bottom of the lower guide rail, and the lower support plate covers the bottom of the hinged door leaf.

[0017] The beneficial effects of this invention are: 1. Simple structure, low production cost, and improved market competitiveness.

[0018] In this invention, a hinged door and a sliding door are joined together, and the advantages of the two opening modes are complemented by a sophisticated guide rail docking mechanism.

[0019] It completely solves the problem of traditional sliding doors only being able to open half the space and restricting the entry and exit of items, providing users with an unprecedentedly large operating space and unobstructed view, greatly improving the convenience of storing and retrieving items and the user experience.

[0020] While achieving a large opening, it effectively avoids excessive occupation of interior space when the hinged door is open. When it is not necessary to open it fully, the sliding door can still be used as an independent flat sliding door, which is convenient for frequent small-scale opening and closing in daily life; 5. This invention ensures smooth communication between the first and second guide rails through the precise cooperation of the movable and fixed docking seats. Simultaneously, the ingenious combination of the locking block and the linkage mechanism, along with its linkage with the connecting seat, ensures reliable restriction of the sliding of the hanging wheel assembly when the door is closed, guaranteeing the stability and safety of the system under different conditions. This integrated design not only improves the reliability of the system but also simplifies the user's operation, enabling both smooth sliding and secure locking. Attached Figure Description

Detailed Implementation

[0031] The invention will be further described below with reference to the accompanying drawings. A splicing door system includes a hinged door leaf 3 mounted on a door frame 2 via a door hinge 1, and a first guide rail 4 is fixedly mounted on the top of the hinged door leaf 3; It also includes a second guide rail 5 fixed to the top of the door frame 2, and a sliding door leaf 7 is slidably installed in the second guide rail 5 through a set of hanging wheels 6; It also includes a movable docking seat 8 installed at the end of the first guide rail 4 and a fixed docking seat 9 installed at the end of the second guide rail 5. When the door leaf 3 is closed, the movable docking seat 8 and the fixed docking seat 9 dock with each other, so that the first guide rail 4 and the second guide rail 5 are connected. It also includes a locking block 81 disposed in the movable docking seat 8. The locking block 81 is linked to the linkage seat 21 disposed on the door frame 2 through a linkage mechanism. When the door leaf 3 is closed, the linkage seat 21 drives the linkage mechanism to disengage the locking block 81 from the first guide rail 4. When the door leaf 3 is opened, the linkage seat 21 separates from the linkage mechanism, and the locking block 81 is inserted into the first guide rail 4 to restrict the sliding of the hanging wheel assembly 6. It also includes a lower guide rail 31 provided on the back of the hinged door 3, and correspondingly, a lower guide block 71 is provided on the back of the sliding door 7, and the lower guide block 71 slides within the lower guide rail 31.

[0032] In this embodiment: when the door leaf 3 is in the closed state, the movable docking seat 8 installed at the end of the first guide rail 4 precisely docks with the fixed docking seat 9 installed at the end of the second guide rail 5. This docking physically connects the originally separate first guide rail 4 and second guide rail 5, forming a continuous guide rail channel.

[0033] To control the sliding timing of the sliding door 7, this system incorporates a locking mechanism. When the hinged door 3 is closed to the designated position, the linkage seat 21 on the door frame 2 contacts and drives the linkage mechanism within the movable docking seat 8. This linkage mechanism then drives the locking block 81 to retract from the path of the first guide rail 4, thereby releasing the restriction on the roller assembly 6 and allowing the sliding door 7 to slide freely along the connected first guide rail 4 and second guide rail 5. Conversely, when the hinged door 3 is opened, the linkage seat 21 separates from the linkage mechanism, and the locking block 81, under the action of force, pops out again and inserts into the path of the first guide rail 4, locking the roller assembly 6, thus restricting the sliding of the sliding door 7 when the hinged door 3 is open, preventing misoperation or accidental movement.

[0034] The lower guide rail 31 on the back of the hinged door 3 cooperates with the lower guide block 71 on the back of the sliding door 7. The lower guide block 71 slides within the lower guide rail 31, providing lower guidance and support for the smooth sliding of the sliding door 7 and preventing wobbling.

[0035] In one embodiment: the movable docking seat 8 is provided with a first fitting area 82 at one end facing the first guide rail 4, and the movable docking seat 8 is fitted and fixed to the end of the first guide rail 4 through the first fitting area 82; the fixed docking seat 9 is provided with a second fitting area 91 at one end facing the second guide rail 5, and the fixed docking seat 9 is fitted and fixed to the end of the second guide rail 5 through the second fitting area 91.

[0036] In this embodiment, the movable docking seat 8 is tightly fixed to the end of the first guide rail 4 in a fitted manner via its first fitting area 82. Similarly, the fixed docking seat 9 is fitted and fixed to the end of the second guide rail 5 via its second fitting area 91.

[0037] This set of fixing provides a more secure connection than simple screw fixing, ensuring the reliability and stability of the connection between the docking seat and the guide rail, reducing shaking and loosening, and guaranteeing the accuracy of guide rail docking and the smoothness of connection.

[0038] In one embodiment: a positioning buckle 83 is provided on the end face of the movable docking seat 8 facing the fixed docking seat 9, and correspondingly: an elastic groove 92 is provided on the end face of the fixed docking seat 9 facing the movable docking seat 8. When the door 3 is closed, the positioning buckle 83 is engaged in the elastic groove 92.

[0039] In this embodiment: when the hinged door 3 is closed, and the movable docking seat 8 and the fixed docking seat 9 approach and engage, the positioning buckle 83 on the movable docking seat 8 will precisely engage into the elastic groove 92 on the fixed docking seat 9. The cooperation between the positioning buckle and the elastic groove ensures precise and reliable alignment and engagement between the movable and fixed docking seats when the hinged door is closed, guaranteeing smooth communication between the two guide rails. Simultaneously, the buckling mechanism provides additional locking force, preventing the hinged door from accidentally opening or shaking due to external force after closing, thus enhancing the overall stability of the system.

[0040] In addition, the "click" sound or tactile feedback when the door is latched provides users with clear feedback that the door is closed properly.

[0041] In one embodiment: the fixed docking seat 9 is provided with a guide groove 93, and the elastic slider 94 is slidably installed in the guide groove 93. A first spring 95 is provided between the guide groove 93 and the elastic slider 94. The first spring 95 pushes the elastic slider 94 to pop outward at all times. The elastic groove 92 is provided on the end face of the elastic slider 94.

[0042] In this embodiment, the elastic groove 92 is not a fixed structure, but is disposed on the end face of a slidable elastic slider 94. The elastic slider 94 is slidably mounted in the guide groove 93 on the fixed docking seat 9. A first spring 95 is disposed between the guide groove 93 and the elastic slider 94, and its function is to continuously push the elastic slider 94 outward.

[0043] When the positioning buckle 83 on the movable docking seat 8 contacts the elastic groove 92, it will overcome the elastic force of the first spring 95 and push the elastic slider 94 inward. When the positioning buckle 83 is fully inserted into the elastic groove 92, the spring force will push the elastic slider 94 back, thereby realizing the snapping and fixing of the positioning buckle 83.

[0044] The design of the elastic slider and spring provides cushioning and flexibility for the locking process of the positioning buckle, avoiding rigid impacts, reducing wear, and extending service life. Furthermore, the spring preload ensures that the elastic groove remains in an outward-expanding state, guaranteeing reliable engagement of the positioning buckle and improving locking reliability. The elastic mechanism also allows the positioning buckle to smoothly disengage from the elastic groove by overcoming the spring force when the door needs to be opened, ensuring smooth operation.

[0045] In one embodiment: the linkage mechanism includes a locking hole 84 disposed in the movable docking seat 8, a sliding block 85 disposed at the rear end of the locking block 81, and a plurality of guide posts 86 disposed on the sliding block 85; it also includes a transverse groove 87 disposed on the movable docking seat 8, a pushing block 88 is slidably installed in the transverse groove 87, and a plurality of inclined pressing grooves 89 are disposed on the pushing block 88, the guide posts 86 extend into the pressing grooves 89, and when the pushing block 88 slides along the transverse groove 87, it drives the locking block 81 to slide back and forth in the locking hole 84 through the pressing grooves 89.

[0046] In this embodiment, the forward and backward sliding of the locking block 81 is achieved by the cooperation of the guide post 86 on the sliding block 85 at its rear end and the inclined pressing groove 89 on the pushing block 88. The pushing block 88 itself slides laterally within the transverse groove 87 of the movable docking seat 8.

[0047] When the push block 88 slides laterally along the transverse groove 87, the inclined compression groove 89 exerts an oblique compression force on the guide post 86 that enters it. This force is decomposed into a transverse force and a longitudinal force. The longitudinal force drives the guide post 86 and the connected sliding block 85 and locking block 81 to slide back and forth within the locking hole 84.

[0048] By combining the inclined extrusion groove and the guide post, the lateral movement of the push block is precisely converted into the longitudinal movement of the locking block, thus achieving effective force transmission and precise motion control.

[0049] In one embodiment: a second spring 810 is provided between the movable docking seat 8 and the sliding block 85, and the second spring 810 pushes the locking block 81 to move in the direction of insertion into the first guide rail 4.

[0050] In this embodiment, a second spring 810 is provided between the movable docking seat 8 and the sliding block 85 of the locking block 81. This spring is always compressed, and its elastic force drives the locking block 81 to pop outward, causing it to tend to insert into the path of the first guide rail 4. This ensures that the locking block can automatically reset and insert into the guide rail in the absence of external force, i.e., when the sliding door is open, thereby reliably limiting the sliding of the sliding door and enhancing safety.

[0051] In one embodiment: a pressing wheel 22 is installed on the linkage seat 21. Correspondingly, a recessed positioning area 811 is provided on the push block 88 at the position of the pressing wheel 22. When the door 3 is closed, the pressing wheel 22 is engaged in the positioning area 811 and the push block 88 slides laterally along the transverse groove 87.

[0052] In this embodiment: when the door 3 is closed, the movable docking seat 8 moves accordingly, and the push block 88 on it approaches the linkage seat 21. The pressing wheel 22 engages with the recessed positioning area 811 on the push block 88. During the engagement process, the pressing wheel 22 applies a force to the push block 88, causing it to slide laterally along the transverse groove 87. This sliding is the direct cause of triggering the locking block 81. Therefore, the cooperation between the pressing wheel and the recessed positioning area ensures that the locking block is triggered only when the door is closed to the precise position, improving the accuracy of the system. At the same time, the roller structure reduces sliding friction, making the force transmission process smoother and reducing jamming.

[0053] In one embodiment: the lower guide rail 31 has a "Z" shaped cross section, and its top and the sliding door 3 form a top opening guide area 32; the lower guide block 71 includes a guide seat 711 connected to the sliding door 7, the guide seat 711 extends downward and is provided with a guide head 712, the guide head 712 extends into the guide area 32 and slides.

[0054] In this embodiment, the lower guide rail 31 has a Z-shaped cross-section, which creates an upward-opening guide area 32 between the top of the lower guide rail and the sliding door 3. The lower guide block 71 consists of a guide seat 711 connecting the sliding door 7 and a downward-extending guide head 712. The guide head 712 slides within the guide area 32 of the Z-shaped lower guide rail.

[0055] The design of the "Z"-shaped guide rail combined with the guide head provides stable guidance for the sliding door, preventing it from swaying left and right or derailing upwards during the sliding process.

[0056] In one embodiment: the guide head 712 is provided with an isolation block 713 protruding in the direction of the sliding door 7, and the isolation block 713 is in contact with the lower guide rail 31.

[0057] In this embodiment, the isolation block is usually made of wear-resistant materials such as plastic and nylon, which can effectively reduce the friction between metals and the noise generated when in contact with the lower guide rail, making the sliding door slide more smoothly and quietly.

[0058] Meanwhile, the isolation block can prevent the metal part of the guide head from directly wearing down the lower guide rail, thus extending the service life of the guide rail.

[0059] In one embodiment, a lower support plate 33 extends forward from the bottom of the lower guide rail 31, covering the bottom of the hinged door 3. The cooperation between the bottom of the hinged door 3 and the lower support plate restricts the installation position of the lower guide rail, allowing for accurate installation without the need for tools.

[0060] In summary, the core of the splicing door system of this invention lies in its ingenious mechanical linkage mechanism, which enables seamless switching and coordinated operation of the hinged door leaf 3 and the sliding door leaf 7 between different opening modes. This overcomes the limitations of traditional sliding doors and hinged doors, and its operation exhibits the following combined states: 1. System initial state: Door closed. When the system is fully closed, the hinged door 3 is tightly closed onto the door frame 2 via the hinge 1. At this time, the movable docking seat 8 of the first guide rail 4 at the top of the hinged door 3 and the fixed docking seat 9 of the second guide rail 5 at the top of the door frame 2 are precisely docked. This docking is achieved by the locking buckle 83 on the movable docking seat 8 engaging with the elastic groove 92 on the elastic slider 94 inside the fixed docking seat 9, ensuring tight alignment and smooth conduction of the two guide rails. Simultaneously, during the closing process of the hinged door 3, the pressing wheel 22 of the linkage seat 21 on the door frame 2 engages and drives the push block 88 inside the movable docking seat 8 to slide laterally along the transverse groove 87. This sliding drives the guide post 86 of the locking block 81 through the inclined pressing groove 89 on the push block 88, causing the locking block 81 to retract inward within the locking hole 84, thereby releasing the restriction on the sliding door 7 hanging wheel assembly 6. At this time, the sliding door 7 can slide freely on the first guide rail 4 and the second guide rail 5 after conduction.

[0061] 2. Sliding door panel sliding mode: When a user only needs to open the door in a limited space, such as when retrieving small items from a cabinet or when the doorway is only wide enough for one person to pass through, the sliding door 7 can be directly pushed by the user since the hinged door 3 is closed, the guide rails are open, and the locking block 81 is retracted. This allows the sliding door 7 to slide laterally along the first and second guide rails 4 and 5 via the roller assembly 6. The lower guide block 71 on the back of the sliding door 7 has a guide head 712 that slides within the guide area 32 of the "Z"-shaped lower guide rail 31 on the back of the hinged door 3, assisted by the isolation block 713, providing stable support and guidance for the sliding. In this mode, the system functions like a regular sliding door, without occupying additional space for outward swinging.

[0062] 3. The hinged door and sliding door work together to open to full mode: This is the most significant advantage of the present invention. With the hinged door 3 closed and the guide rail open, if the user needs to maximize the opening, they can push the sliding door 7 along the open guide rail, allowing it to fully enter the first guide rail 4 and overlap with the hinged door 3. At this time, the sliding door 7 is located "behind" the hinged door 3, and viewed from the outside of the doorway, the two are almost side-by-side. Then, the user can grasp the hinged door 3 and pull it outwards, just like operating a regular hinged door. Since the sliding door 7 has overlapped with the hinged door 3 and is within its movable range, when the hinged door 3 swings outwards around the hinge 1, it will naturally cause the already overlapping sliding door 7 to swing outwards as well. In this way, the doorway area originally occupied by the two doors is almost completely opened, achieving a "fully open" effect for the cabinet or passageway, greatly facilitating the entry and exit of large items or maximizing passage.

[0063] 4. Door closing and resetting: When the door system needs to be closed, first pull the hinged door 3 back to the closed position. As the hinged door 3 closes, the sliding door 7, which overlaps with it, will also be pulled back. Once the hinged door 3 is fully closed, the linkage seat 21 on the door frame 2 and the linkage mechanism separate the positioning area on the push block 88. Under the elastic force of the second spring 810 set between the movable docking seat 8 and the sliding block 85, the locking block 81 automatically pops out and inserts into the path of the first guide rail 4, re-restricting the sliding of the hanging wheel assembly 6. At this point, the entire door system returns to its initial closed state, the sliding door 7 is locked, and the stability and safety of the system are ensured once again.

[0064] Compared to traditional technologies, this modular door system successfully integrates the space-saving characteristics of sliding doors and the full-opening advantage of hinged doors through its ingenious mechanical design and linkage mechanism. When the hinged door is closed, a precise guide rail docking mechanism and a linkage locking mechanism allow the sliding door panels to slide freely. More importantly, when the sliding door panels overlap with the hinged door panels, they can open together, providing an exceptionally large opening space that traditional sliding doors cannot achieve. This not only greatly improves the convenience and flexibility of user operation but also optimizes the utilization of indoor space, making it a new type of door system with significant advancements in both functionality and adaptability, thus deserving widespread application.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
