Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furniture, in particular to a spliced door system. BACKGROUND

[0002] In today's architectural and home design, doors as an important component to connect and separate spaces, its opening mode and space occupation has always been a trade-off factor. The door system on the market mainly includes two basic forms of flat sliding door (or called sliding door) and cover door (or called swing door).

[0003] A common door system is flat sliding door. Flat sliding door usually installs guide rail on the top or bottom of the door frame, so that the door leaf can slide horizontally in the guide rail, thereby realizing the opening or closing of the space. The advantage of this opening mode is that the door leaf does not need to occupy extra space outwardly or inwardly when it is opened, which has obvious space saving advantage for limited space area, such as narrow corridor or compact indoor layout. However, flat sliding door also has its inherent disadvantages. For example, in multi-door design, since the door leaves usually slide side by side, only one or one side door leaf can be opened each time, thereby limiting the complete exposure of the entrance or cabinet opening and the operation space of the user. For the situation that needs to be opened in a large area to facilitate the access of goods or the passage of people, flat sliding door is not flexible and convenient enough.

[0004] Another common door system is cover door. Cover door is installed on the door frame through hinge, and the door leaf can be opened inwardly or outwardly around the hinge axis. The main advantage of cover door is that when the door leaf is completely opened, it can realize the full exposure of the door hole or cabinet inside, providing an unobstructed full opening effect, which greatly facilitates the access of goods and the activities of the user. However, the disadvantages of cover door are also prominent. When the cover door is opened, the door leaf will swing outwardly or inwardly, occupying an extra space of the size of the door leaf itself. This means that enough space must be reserved in the opening direction of the door leaf, otherwise it will hinder the complete opening of the door leaf, and even collide with the indoor furniture or wall. Therefore, for the environment with limited indoor space, especially the narrow area in front of the door or cabinet, the use of cover door will be greatly limited, which puts higher space requirements on indoor layout and furniture placement.

[0005] In summary, neither flat sliding door nor cover door can find the best balance between "space occupation" and "opening size". In the prior art, there is a lack of a door system that can flexibly choose the opening mode according to the actual needs, which can realize complete opening and facilitate the access of large goods, and can also open in a space-saving way when necessary. This leads users to have to make compromises when choosing a door system, which cannot fully meet the diversified use scenarios and the growing demand for space utilization efficiency, so it is necessary to make further improvements.

DETAILED DESCRIPTION

[0033] The application will be further described below in conjunction with the drawings. A spliced door system comprises a cover door leaf 3 installed on a door frame 2 through a door hinge 1, and a first guide rail 4 fixedly installed on the top of the cover door leaf 3; It also comprises a second guide rail 5 fixed on the top of the door frame 2, and a sliding door leaf 7 slidably installed in the second guide rail 5 through a lifting wheel set 6; It also comprises a movable butt joint seat 8 installed at the end of the first guide rail 4, and a fixed butt joint seat 9 installed at the end of the second guide rail 5, and when the cover door leaf 3 is closed, the movable butt joint seat 8 and the fixed butt joint seat 9 are mutually butted, so that the first guide rail 4 and the second guide rail 5 are in communication; It also comprises a locking block 81 arranged in the movable butt joint seat 8, and the locking block 81 is linked with a linkage seat 21 arranged on the door frame 2 through a linkage mechanism, and when the cover door leaf 3 is closed, the linkage seat 21 drives the linkage mechanism to make the locking block 81 disengage from the first guide rail 4; when the cover door leaf 3 is opened, the linkage seat 21 is separated from the linkage mechanism, and the locking block 81 is inserted into the first guide rail 4 to limit the sliding of the lifting wheel set 6; It also comprises a lower guide rail 31 arranged on the back of the cover door leaf 3, and correspondingly, a lower guide block 71 is arranged on the back of the sliding door leaf 7, and the lower guide block 71 slides in the lower guide rail 31.

[0034] In this embodiment: when the cover door leaf 3 is in the closed state, the movable butt joint seat 8 installed at the end of the first guide rail 4 is precisely butted with the fixed butt joint seat 9 installed at the end of the second guide rail 5. This butt joint makes the originally separated first guide rail 4 and second guide rail 5 physically communicate, forming a continuous guide rail channel.

[0035] Wherein, in order to control the sliding timing of the wicket fan 7, the system is provided with a locking mechanism. When the shutter fan 3 is closed to the specified position, the linkage seat 21 on the door frame 2 will contact and drive the linkage mechanism in the movable butt joint seat 8. The linkage mechanism in turn drives the locking block 81 to retract from the path of the first guide rail 4, thereby releasing the restriction of the hanging wheel set 6, allowing the wicket fan 7 to slide freely along the first guide rail 4 and the second guide rail 5 after being guided. Conversely, when the shutter fan 3 is opened, the linkage seat 21 is separated from the linkage mechanism, and the locking block 81 is driven by the force to pop out and insert into the path of the first guide rail 4, clamping the hanging wheel set 6, thereby restricting the sliding of the wicket fan 7 in the state that the shutter fan 3 is opened, preventing misoperation or accidental movement.

[0036] Wherein, the lower guide rail 31 provided on the back of the shutter fan 3 cooperates with the lower guide block 71 provided on the back of the wicket fan 7, and the lower guide block 71 slides in the lower guide rail 31, providing lower guidance and support for the smooth sliding of the wicket fan 7, preventing shaking.

[0037] In one embodiment: the movable butt joint seat 8 is provided with a first fitting area 82 at one end towards the first guide rail 4, and the movable butt joint seat 8 is fitted and fixed at the end of the first guide rail 4 through the first fitting area 82; the fixed butt joint seat 9 is provided with a second fitting area 91 at one end towards the second guide rail 5, and the fixed butt joint seat 9 is fitted and fixed at the end of the second guide rail 5 through the second fitting area 91.

[0038] In this embodiment: the movable butt joint seat 8 is tightly fixed at the end of the first guide rail 4 in a fitted manner through its own first fitting area 82. Similarly, the fixed butt joint seat 9 is fitted and fixed at the end of the second guide rail 5 through its second fitting area 91.

[0039] This fitted fixing provides a more stable connection than simple screw fixing, ensuring the firmness and stability of the connection between the butt joint seat and the guide rail, reducing shaking and loosening, and ensuring the accuracy of the butt joint and the smoothness after being guided.

[0040] In one embodiment: the movable butt joint seat 8 is provided with a positioning buckle 83 on the end face towards the fixed butt joint seat 9, and correspondingly: the fixed butt joint seat 9 is provided with an elastic groove 92 on the end face towards the movable butt joint seat 8, and the positioning buckle 83 is buckled into the elastic groove 92 when the shutter fan 3 is closed.

[0041] In this embodiment: when the shutter leaf 3 is closed in place, the movable docking seat 8 is close to and docks with the fixed docking seat 9, the positioning buckle 83 on the movable docking seat 8 will be accurately buckled into the elastic groove 92 on the fixed docking seat 9. The cooperation of the positioning buckle and the elastic groove can ensure that the movable docking seat and the fixed docking seat are accurately and reliably aligned and docked when the shutter is closed, ensuring smooth conduction of the two guide rails. At the same time, the buckling mechanism provides additional locking force to prevent the shutter leaf from accidentally opening or shaking after being closed due to external force, enhancing the overall stability of the system.

[0042] In addition, the "click" sound or feel when buckling provides the user with clear feedback that the door leaf has been closed in place.

[0043] In one of the embodiments: the fixed docking seat 9 is provided with a guide groove 93, and a elastic sliding block 94 is slidingly installed in the guide groove 93, a first spring 95 is arranged between the guide groove 93 and the elastic sliding block 94, the first spring 95 always pushes the elastic sliding block 94 to pop out outward, and the elastic groove 92 is arranged on the end face of the elastic sliding block 94.

[0044] In this embodiment: the elastic groove 92 is not a fixed structure, but is arranged on the end face of a slidable elastic sliding block 94. The elastic sliding block 94 is slidingly installed in the guide groove 93 on the fixed docking seat 9. The first spring 95 is arranged between the guide groove 93 and the elastic sliding block 94, which continuously pushes the elastic sliding block 94 outward.

[0045] When the positioning buckle 83 on the movable docking seat 8 contacts the elastic groove 92, it will push the elastic sliding block 94 inward against the elastic force of the first spring 95, and when the positioning buckle 83 completely enters the elastic groove 92, the spring force will push the elastic sliding block 94 back, thereby realizing the buckling and fixing of the positioning buckle 83.

[0046] The design of the elastic sliding block and the spring provides buffering and flexibility for the buckling process of the positioning buckle, avoiding rigid impact, reducing wear and tear, and prolonging the service life. In addition, the pre-tightening force of the spring ensures that the elastic groove can always maintain a state of popping out outward, ensuring that the positioning buckle can be reliably buckled in, improving the reliability of the locking. In addition, the elastic mechanism also makes it possible for the positioning buckle to smoothly disengage from the elastic groove by overcoming the spring force when the shutter leaf needs to be opened, ensuring the smoothness of the operation.

[0047] In one of the embodiments: the linkage mechanism comprises a locking hole 84 arranged in the movable docking seat 8, the rear end of the locking block 81 is provided with a sliding block 85, and a plurality of guide columns 86 are arranged on the sliding block 85; further comprising a transverse slot 87 arranged on the movable docking seat 8, a push block 88 is transversely and slidingly arranged in the transverse slot 87, and a plurality of inclined extrusion grooves 89 are arranged on the push block 88, the guide columns 86 extend into the extrusion grooves 89, and when the push block 88 slides along the transverse slot 87, the locking block 81 is driven to slide forward and backward in the locking hole 84 through the extrusion grooves 89.

[0048] In this embodiment: the forward and backward sliding of the locking block 81 is realized by the cooperation of the guide columns 86 on the rear end of the sliding block 85 and the inclined extrusion grooves 89 on the push block 88. The push block 88 itself slides transversely in the transverse slot 87 of the movable docking seat 8.

[0049] When the push block 88 slides transversely along the transverse slot 87, the inclined extrusion grooves 89 will produce an oblique extrusion on the guide columns 86 entering them, and this force is decomposed into a transverse force and a longitudinal force. The longitudinal force drives the guide columns 86, as well as the sliding block 85 and the locking block 81 connected thereto, to slide forward and backward in the locking hole 84.

[0050] Through the cooperation of the inclined extrusion grooves and the guide columns, the transverse movement of the push block is accurately converted into the longitudinal movement of the locking block, realizing effective force transmission and accurate control of movement.

[0051] In one of the embodiments: a second spring 810 is arranged between the movable docking seat 8 and the sliding block 85, which always drives the locking block 81 to move in the direction of inserting into the first guide rail 4.

[0052] In this embodiment: a second spring 810 is arranged between the movable docking seat 8 and the sliding block 85 of the locking block 81. The spring is always in a compressed state, and its elastic force drives the locking block 81 to pop out, making it tend to insert into the path of the first guide rail 4. It ensures that the locking block can automatically reset and insert into the guide rail in the absence of external force, i.e. when the door leaf is opened, thereby reliably limiting the sliding of the door leaf and enhancing the safety.

[0053] In one of the embodiments: the linkage seat 21 is provided with an extrusion wheel 22, and correspondingly, a concave positioning area 811 is arranged on the push block 88 corresponding to the position of the extrusion wheel 22, when the door leaf 3 is closed, the extrusion wheel 22 buckles into the positioning area 811 and drives the push block 88 to slide transversely along the transverse slot 87.

[0054] In this embodiment, when the shutter leaf 3 is closed, the movable abutment 8 moves with it, and the pushing block 88 on it approaches the connecting seat 21. The pressing wheel 22 is buckled into the inner recessed positioning area 811 on the pushing block 88. During buckling, the pressing wheel 22 exerts force on the pushing block 88, causing it to slide laterally along the lateral slot 87. This sliding is the direct cause of triggering the action of the locking block 81. Therefore, the cooperation of the pressing wheel and the inner recessed positioning area ensures that the action of the locking block is triggered only when the shutter leaf 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 the phenomenon of jamming.

[0055] In one embodiment, the lower guide rail 31 has a "Z" shape in cross-section, and the top part forms a top-opening guide area 32 with the shutter leaf 3. The lower guide block 71 includes a guide seat 711 connected to the shutter leaf 7, and the guide head 712 extends downward into the guide area 32.

[0056] In this embodiment, the lower guide rail 31 has a "Z" shape in cross-section, and the top part forms a top-opening guide area 32 with the shutter leaf 3. The lower guide block 71 includes a guide seat 711 connected to the shutter leaf 7, and the guide head 712 extends downward into the guide area 32.

[0057] The "Z" shaped guide rail combined with the design of the guide head provides stable guidance for the shutter leaf, preventing it from shaking left and right or coming off the track upward during sliding.

[0058] In one embodiment, the guide head 712 is provided with a separation block 713 protruding towards the shutter leaf 7, and the separation block 713 is in contact with the lower guide rail 31.

[0059] In this embodiment, the separation 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 of the shutter leaf smoother and quieter.

[0060] At the same time, the setting of the separation block can avoid the direct wear of the lower guide rail by the metal part of the guide head, prolonging the service life of the guide rail.

[0061] In one embodiment, the lower guide rail 31 has a "Z" shape in cross-section, and the top part forms a top-opening guide area 32 with the shutter leaf 3. The lower guide block 71 includes a guide seat 711 connected to the shutter leaf 7, and the guide head 712 extends downward into the guide area 32.

[0062] In summary: the spliced door system of the present application, the core is to realize seamless switching and collaborative work between the cover door leaf 3 and the approach door leaf 7 in different opening modes through the ingenious mechanical linkage mechanism, so as to overcome the respective limitations of the traditional flat approach door and the cover door, and the working time has the following centralized state: 1. System initial state door leaf closed: When the system is completely closed, the cover door leaf 3 is tightly closed on the door frame 2 through the door hinge 1. At this time, the movable butt joint seat 8 of the first guide rail 4 at the top of the cover door leaf 3 and the fixed butt joint seat 9 of the second guide rail 5 at the top of the door frame 2 have realized accurate butt joint. This butt joint is realized by the positioning buckle 83 on the movable butt joint seat 8 and the elastic groove 92 buckle on the elastic sliding block 94 in the fixed butt joint seat 9, which ensures the close alignment and smooth guide of the two guide rails. At the same time, in the process of closing the cover door leaf 3 in place, the extrusion wheel 22 of the linkage seat 21 on the door frame 2 buckles and drives the push block 88 in the movable butt joint seat 8 to slide horizontally along the horizontal slot 87. The sliding drives the guide column 86 of the locking block 81 through the inclined extrusion slot 89 on the push block 88, so that the locking block 81 retracts inwardly in the locking hole 84, thereby releasing the restriction on the lifting wheel set 6 of the approach door leaf 7. At this time, the approach door leaf 7 can freely slide on the first guide rail 4 and the second guide rail 5 after being guided.

[0063] 2. Approach door leaf sliding alone flat approach mode: When the user only needs to open a limited space, for example, to take small items from the cabinet or to pass through the door hole for one person, since the cover door leaf 3 has been closed and the guide rail is guided, and the locking block 81 has been retracted, the user can directly push the approach door leaf 7 to make it slide horizontally on the first guide rail 4 and the second guide rail 5 after being guided through the lifting wheel set 6. The lower guide block 71 on the back of the approach door leaf 7, the guide head 712 slides in the guide area 32 of the "Z" shaped lower guide rail 31 on the back of the cover door leaf 3, and is assisted by the isolation block 713 to provide stable support and guide for sliding. In this mode, the system is like an ordinary flat approach door, which does not occupy extra outward swinging space.

[0064] 3. Cover door leaf and approach door leaf linkage opening full opening mode: This is the most prominent advantage of the present application. In the state of the closing of the shutter leaf 3 and the guide rail being in the open state, if the user needs to achieve the maximum opening, the user can push the wing leaf 7 along the open guide rail to make it completely enter the first guide rail 4 and overlap with the shutter leaf 3. At this time, the wing leaf 7 is located in the "rear" of the shutter leaf 3 from the outside of the door hole, and the two are almost side by side. Then, the user can operate the shutter leaf 3 and pull it outward like a common shutter. Since the wing leaf 7 has overlapped with the shutter leaf 3 and is within the movable range of the shutter leaf 3, when the shutter leaf 3 swings outward around the door hinge 1, it will naturally drive the overlapped wing leaf 7 to swing outward. In this way, the door hole area originally occupied by the two door bodies is almost completely open, realizing the "full opening" effect of the cabinet or passage, greatly facilitating the entry and exit of large items or maximizing the need for passage.

[0065] 4. Door leaf closing and resetting: When it is necessary to close the door system, the shutter leaf 3 is first pulled back to the closed position. With the closing of the shutter leaf 3, the wing leaf 7 overlapping with the wing leaf 7 is also brought back together. Once the shutter leaf 3 is completely closed in place, the connecting seat 21 on the door frame 2 and the linkage mechanism, the positioning area on the push block 88 are separated, so that under the action of the elastic force of the second spring 810 arranged between the movable abutting seat 8 and the sliding block 85, the locking block 81 is automatically ejected and inserted into the path of the first guide rail 4, re-limiting the sliding of the hanging wheel set 6. At this time, the entire door system returns to the initial closed state, the wing leaf 7 is locked, and the stability and safety of the system are again ensured.

[0066] Compared with the traditional technology, the present spliced door system successfully combines the space saving feature of the flat wing door and the full opening advantage of the shutter door through the above ingenious mechanical design and linkage mechanism. When the shutter door is closed, it realizes the free sliding of the wing door leaf through the precise guide rail abutting mechanism and linkage locking mechanism. More importantly, when the wing door leaf overlaps with the shutter door leaf, it can be swung together with the shutter door leaf, thereby providing an ultra-large opening space that cannot be achieved by traditional wing doors. This not only greatly improves the convenience and flexibility of user operation, but also optimizes the indoor space utilization, making it a new type of door system with significant progress in functionality and adaptability, and therefore can be widely used.

[0067] The basic principles and main features of the present application and the advantages of the present application have been shown and described. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
