Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furniture hardware and cabinet door opening and closing structure, and particularly relates to a full-opening type corner cabinet door system suitable for kitchen corner cabinet, wardrobe corner cabinet, storage cabinet corner cabinet, bathroom cabinet corner cabinet and the like. BACKGROUND

[0002] In kitchens, cloakrooms, storage rooms, bathroom cabinets and custom furniture, corner cabinets are a common cabinet structure. The corner cabinet is usually arranged at the intersection of two cabinet bodies, such as the L-shaped corner area of the kitchen base cabinet, the corner area of the wardrobe or the corner area of the storage cabinet. Since the corner cabinet can utilize the corner of the wall or the corner of the cabinet, it has certain advantages in space arrangement in furniture design.

[0003] However, the existing corner cabinet generally has the problems of low utilization rate of internal space, difficulty in taking out articles, and limited cabinet door opening in actual use. Especially for L-shaped corner cabinets, the interior of the cabinet body usually has a deep corner space, and the area close to the inner side of the corner is far from the cabinet door opening. When storing or taking out articles, the user often needs to bend over, crouch down or stretch his body into the cabinet opening to reach the articles in the deep corner, which is very inconvenient to use.

[0004] In the prior art, in order to close the opening of the corner cabinet, the following cabinet door structures are usually used.

[0005] The first is to use a common swing door structure. This structure usually only has a swing door on one side of the corner cabinet, or has independent swing doors on both sides of the corner. Although the common swing door structure is simple to manufacture, the opening range formed after opening is limited, especially the deep corner is still difficult to expose directly. The user needs to reach in from the small cabinet door opening to take out articles, making it difficult to fully use the space inside the corner. After long-term use, the user will usually only use the outer side space close to the cabinet door opening, and the deep corner area is likely to become idle space, causing waste of internal cabinet space.

[0006] The second is to use a single-sided folding door structure. The single-sided folding door is generally formed by hinging two door panels, which are folded together when opened. This structure can expand the cabinet door opening to some extent, but since the corner cabinet generally has two intersecting openings, when only a single-sided folding door is used, the other side of the corner area is still limited by the door panel, the cabinet side panel or the fixed structure, and cannot be fully opened. Therefore, the internal space of the cabinet corner still has the problems of inconvenience and insufficient utilization.

[0007] The third type uses a turntable, pull-out basket, or linked pull-out mechanism. This type of structure can move items inside the corner cabinet to the cabinet door opening via the turntable or pull-out basket, improving some of the retrieval issues. However, this type of structure usually requires more cabinet space and complex hardware components, slide rail components, or rotating support structures, resulting in higher manufacturing costs and complex installation and debugging. Furthermore, the pull-out basket or turntable itself has fixed dimensions and movement trajectory, which limits the free use of the original storage space inside the cabinet and makes it impossible to flexibly place large or irregularly shaped items according to the user's needs.

[0008] Therefore, it is necessary to provide an improved corner cabinet door system that allows for a larger opening space in both intersecting directions of the corner cabinet, and ensures smooth folding and unfolding of the cabinet door through a guide structure. At the same time, a self-resetting buffer hinge assists in fully opening or closing the cabinet door, thereby improving the utilization rate of the interior space of the corner cabinet, making it easier for users to access items, and improving the cabinet door opening and closing experience. Summary of the Invention

[0009] The purpose of this invention is to provide a fully openable corner cabinet door system to solve the problems of low internal space utilization of existing corner cabinets, difficulty in retrieving items from deep corners, limited opening range of cabinet doors, insufficient stability of folding door opening and closing, and inability to easily open or close cabinet doors completely.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a fully openable corner cabinet door system, comprising a first cabinet and a second cabinet arranged in an L-shape, and two sets of folding door assemblies respectively installed at the openings of the first cabinet and the second cabinet, wherein the opening directions of the two sets of folding door assemblies are opposite. Each set of the folding door assembly includes a first cabinet door and a second cabinet door. One side of the first cabinet door is hinged to the corresponding first cabinet body or second cabinet body via a door hinge, and the other side of the first cabinet door is connected to the second cabinet door via a hinge. Each set of the folding door assembly is provided with a guide rail, which extends along the opening direction of the corresponding first cabinet or second cabinet, and the guide rails of the two sets of the folding door assembly are distributed in an L-shape. The second cabinet door is equipped with a guide device, which slides in conjunction with a corresponding guide rail, allowing the second cabinet door to fold or unfold relative to the first cabinet door under the combined action of the guide device and the guide rail.

[0011] Furthermore, the guiding device includes a guide hinge installed on the second cabinet door, one end of which is connected to the second cabinet door, and the other end is provided with a guide wheel, which extends into the guide groove of the guide rail and slides.

[0012] Furthermore, two guide wheels are arranged side by side, and an anti-detachment wheel is also provided on the guide hinge. The guide wheel slides in the guide groove of the guide rail, and the anti-detachment wheel slides on the outside of the guide rail. A clamping groove is formed between the guide wheel and the anti-detachment wheel, and the clamping groove is clamped on the groove wall of the guide rail.

[0013] Furthermore, the second cabinet doors of the two sets of folding door assemblies are arranged adjacent to each other in the corner area of ​​the first cabinet and the second cabinet when closed.

[0014] Furthermore, the guide hinge is located at the lower part of the second cabinet door, and correspondingly, the guide rail is located at the lower part of the corresponding first cabinet or second cabinet.

[0015] Furthermore, the guide hinge is located on the upper part of the second cabinet door, and correspondingly, the guide rail is located on the upper part of the corresponding first cabinet or second cabinet.

[0016] Furthermore, two guide hinges are provided, one on the upper part and the other on the lower part of the second cabinet door; correspondingly, two guide rails are provided, one on the upper part and the other on the lower part of the corresponding first cabinet or second cabinet, and each cooperates with the corresponding guide hinge.

[0017] Furthermore, the door hinge is a self-resetting buffer hinge, and there are two door hinges, which are distributed vertically at intervals along the height direction of the first cabinet door.

[0018] Furthermore, when the first cabinet door is closed to a set closing angle, the self-resetting buffer hinge can push the first cabinet door and the second cabinet door connected thereto to be completely closed; when the first cabinet door is opened to a set opening angle, the self-resetting buffer hinge can push the first cabinet door and the second cabinet door connected thereto to be completely opened.

[0019] Furthermore, two hinges are provided, and the two hinges are distributed vertically at intervals along the height direction of the first cabinet door and the second cabinet door.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This invention, by installing two sets of folding door assemblies at the openings of the first and second cabinets arranged in an L-shape, and setting the opening directions of the two sets of folding door assemblies in opposite directions, allows the corner cabinet to be opened in both intersecting directions. Compared with traditional single-sided cabinet doors or single-sided folding doors, this invention can significantly expand the opening range of the corner cabinet, fully exposing the interior of the corner cabinet, especially the deep corner area, making it easier for users to observe, store, and retrieve items.

[0021] 2. Each folding door assembly of the present invention includes a first cabinet door and a second cabinet door. The first cabinet door is hinged to the corresponding cabinet body via a hinge, and the second cabinet door is connected to the first cabinet door via a hinge, enabling each folding door assembly to form a folding opening and closing structure. When opened, the second cabinet door can fold relative to the first cabinet door, reducing the space occupied by the cabinet door outwards; when closed, the first and second cabinet doors can unfold and cover the corresponding cabinet openings, ensuring the integrity of the cabinet's appearance.

[0022] 3. This invention provides corresponding guide rails for each folding door assembly, and the two sets of guide rails are distributed in an L-shape, which is adapted to the L-shaped intersection structure of the first and second cabinets. The guide device on the second cabinet door slides in cooperation with the guide rail, so that the second cabinet door can move along a predetermined trajectory during opening and closing, avoiding free swinging of the second cabinet door and improving the stability and smoothness of the cabinet door opening and closing process.

[0023] 4. The guiding device of the present invention includes a guiding hinge, a guiding wheel, and an anti-detachment wheel. The guiding wheel slides within the guide groove of the guide rail, and the anti-detachment wheel slides outside the guide rail. A clamping groove is formed between the guiding wheel and the anti-detachment wheel, and the clamping groove is clamped onto the groove wall of the guide rail. This prevents the guiding device from detaching from the guide rail during the opening and closing of the cabinet door, thereby improving the operational reliability of the second cabinet door.

[0024] 5. The door hinge of this invention adopts a self-resetting buffer hinge. When the first cabinet door is closed to a set closing angle, the self-resetting buffer hinge can push the first cabinet door and the second cabinet door connected to it to close completely; when the first cabinet door is opened to a set opening angle, the self-resetting buffer hinge can push the first cabinet door and the second cabinet door connected to it to open completely. This reduces the user's manual pushing and pulling operation of the cabinet door, making the opening and closing of the cabinet door more effortless and smooth, and reducing the possibility of the cabinet door not being fully closed or fully opened.

[0025] 6. This invention can improve the utilization rate of the interior space of corner cabinets. Since the cabinet doors can be fully opened, users can more easily access the space deep inside the corner cabinet, thereby improving the storage availability of the corner area and avoiding the problem of the deep space of traditional corner cabinets being idle or difficult to use.

[0026] 7. The structure of this invention is relatively simple, mainly consisting of a cabinet body, folding door assembly, door hinges, guide device and guide rail. It does not require complex pull-out baskets, turntables or large linkage mechanisms inside the cabinet body. Therefore, it can improve the convenience of retrieving items while preserving as much complete storage space as possible inside the cabinet body, making it suitable for use in various corner cabinet products.

[0037] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Unless otherwise specified, the embodiments and technical features described in this specification can be combined with each other.

[0038] like Figures 1 to 9 As shown, this embodiment provides a fully openable corner cabinet door system, which includes a first cabinet body 1, a second cabinet body 2, two sets of folding door assemblies 3, door hinges 4, a guide device 5, and a guide rail 6.

[0039] The first cabinet 1 and the second cabinet 2 are arranged in an L-shape. Specifically, the first cabinet 1 and the second cabinet 2 can be two adjacent cabinets in a kitchen base cabinet, or two adjacent cabinets in a wardrobe, storage cabinet, bathroom cabinet, or other furniture. The first cabinet 1 and the second cabinet 2 form a corner storage space at the corner, which is usually located in the inner area where the two cabinets intersect.

[0040] Two sets of folding door assemblies 3 are respectively installed at the openings of the first cabinet 1 and the second cabinet 2. That is, one set of folding door assemblies 3 is used to open or close the opening in the corresponding direction of the first cabinet 1, and the other set of folding door assemblies 3 is used to open or close the opening in the corresponding direction of the second cabinet 2. The two sets of folding door assemblies 3 are set in opposite directions, so that the two sets of folding door assemblies 3 can fold and unfold in different directions when opened, thereby releasing the two openings of the L-shaped corner cabinet.

[0041] Each folding door assembly 3 includes a first cabinet door 31 and a second cabinet door 32. The first cabinet door 31 is the door panel near the hinged edge on the outer side of the corresponding cabinet, and the second cabinet door 32 is the door panel near the corner area or away from the hinge 4. One side of the first cabinet door 31 is hinged to the corresponding first cabinet 1 or second cabinet 2 via the hinge 4, and the other side of the first cabinet door 31 is connected to the second cabinet door 32 via a hinge 33. Thus, the first cabinet door 31 can rotate relative to the corresponding cabinet, and the second cabinet door 32 can fold or unfold relative to the first cabinet door 31.

[0042] In the closed state, the first cabinet door 31 and the second cabinet door 32 are roughly in the open state and together cover the opening of the corresponding cabinet. The second cabinet doors 32 of the two sets of folding door assemblies 3 are arranged adjacent to each other in the corner area of ​​the first cabinet 1 and the second cabinet 2 in the closed state, so that the two sets of folding door assemblies 3 can form a relatively complete cabinet door sealing surface at the corner position, thereby ensuring the overall appearance of the corner cabinet is neat.

[0043] In the open state, the first cabinet door 31 rotates relative to the corresponding cabinet body around the hinge 4, while the second cabinet door 32 moves along a predetermined trajectory under the cooperation of the guide device 5 and the guide rail 6, and folds relative to the first cabinet door 31. Since the opening directions of the two sets of folding door assemblies 3 are set in opposite directions, the cabinet doors corresponding to the first cabinet body 1 and the second cabinet body 2 can open in different directions, thereby creating a large open space in the corner area.

[0044] Each folding door assembly 3 is equipped with a corresponding guide rail 6. The guide rail 6 extends along the opening direction of the corresponding first cabinet 1 or second cabinet 2, and the guide rails 6 of the two folding door assemblies 3 are distributed in an L-shape. Through this L-shaped guide rail structure, the guide rail 6 can be adapted to the first cabinet 1 and second cabinet 2 arranged in an L-shape, so that the two folding door assemblies 3 can move stably in their respective directions.

[0045] A guide groove 61 is formed on the guide rail 6. The guide groove 61 is used for the guide wheel 52 of the guide device 5 to enter and slide along the guide rail 6. The guide groove 61 can extend along the length of the guide rail 6, so that the guide wheel 52 can move along the guide groove 61, thereby limiting the movement trajectory of the second cabinet door 32.

[0046] A guide device 5 is installed on the second cabinet door 32. The guide device 5 slides in conjunction with the corresponding guide rail 6, allowing the second cabinet door 32 to fold or unfold relative to the first cabinet door 31 under the combined action of the guide device 5 and the guide rail 6. By setting the guide device 5, the second cabinet door 32 is no longer a completely free-swinging door panel, but can be constrained by the guide rail 6 and move along a predetermined trajectory, thus improving the stability of the folding door assembly 3 during opening and closing.

[0047] Specifically, the guiding device 5 includes a guide hinge 51, a guide wheel 52, and an anti-detachment wheel 53. The guide hinge 51 is mounted on the second cabinet door 32. One end of the guide hinge 51 is connected to the second cabinet door 32, and the other end is provided with the guide wheel 52. The guide wheel 52 extends into the guide groove 61 of the guide rail 6 and can slide along the guide groove 61.

[0048] In this embodiment, two guide wheels 52 are arranged side by side. The two guide wheels 52 can jointly support the guide hinge 51 and cooperate with the guide groove 61 of the guide rail 6, thereby improving the stability of the guide device 5 during sliding and reducing the shaking caused by the force deviation of a single guide wheel.

[0049] The guide hinge 51 is also equipped with an anti-detachment wheel 53. The guide wheel 52 slides within the guide groove 61 of the guide rail 6, while the anti-detachment wheel 53 slides outside the guide rail 6. A clamping groove 54 is formed between the guide wheel 52 and the anti-detachment wheel 53, and the clamping groove 54 clamps onto the groove wall of the guide rail 6. Through the clamping cooperation between the clamping groove 54 and the groove wall of the guide rail 6, the guide device 5 can be prevented from detaching from the guide rail 6 during opening and closing, and the swaying of the second cabinet door 32 in the direction perpendicular to the guide rail 6 can also be limited.

[0050] Therefore, during the opening and closing of the cabinet door, the second cabinet door 32 drives the guide wheel 52 to slide along the guide groove 61 through the guide hinge 51, and the anti-detachment wheel 53 moves synchronously along the outside of the guide rail 6. The guide wheel 52 and the anti-detachment wheel 53 together clamp the groove wall of the guide rail 6, so that the second cabinet door 32 can be stably folded or unfolded relative to the first cabinet door 31.

[0051] In one embodiment, the guide hinge 51 is located at the lower part of the second cabinet door 32, and correspondingly, the guide rail 6 is located at the lower part of the corresponding first cabinet 1 or second cabinet 2. This structure is suitable for bottom-guided systems, and the guide rail 6 can be installed on the cabinet bottom plate or bottom support structure, which facilitates the guide device 5 to bear part of the weight of the second cabinet door 32 and improves the operational stability when the cabinet door is opened and closed.

[0052] In another embodiment, the guide hinge 51 is located on the upper part of the second cabinet door 32, and correspondingly, the guide rail 6 is located on the upper part of the corresponding first cabinet 1 or second cabinet 2. This structure is suitable for top-guided systems, can reduce the impact of the bottom guide rail on the storage space at the bottom of the cabinet, and allows for selection of the installation position according to the cabinet structure requirements.

[0053] In another embodiment, two guide hinges 51 are provided, one at the top and one at the bottom of the second cabinet door 32, respectively. Correspondingly, two guide rails 6 are provided, one at the top and one at the bottom of the corresponding first cabinet 1 or second cabinet 2, and each engages with a corresponding guide hinge 51. The cooperation of the upper and lower double guide rails and the upper and lower double guide hinges 51 further improves the operational stability of the second cabinet door 32 and reduces tilting, swaying, or sagging of the second cabinet door 32 during opening and closing.

[0054] A hinge 4 is disposed between the first cabinet door 31 and the corresponding cabinet body. Two hinges 4 can be provided, and the two hinges 4 are distributed vertically at intervals along the height direction of the first cabinet door 31. By providing two hinges 4 vertically at intervals, the connection strength between the first cabinet door 31 and the corresponding cabinet body can be improved, and the force on the first cabinet door 31 can be more evenly distributed during opening and closing.

[0055] In this embodiment, the door hinge 4 is a self-resetting buffer hinge. The self-resetting buffer hinge has both automatic reset and buffering functions. When the first cabinet door 31 is closed to a set closing angle, the self-resetting buffer hinge can push the first cabinet door 31 and the connected second cabinet door 32 to close completely. That is, the user only needs to push the folding door assembly 3 to a position close to the door; once the first cabinet door 31 reaches the set closing angle, the self-resetting buffer hinge can provide a force to continue closing, causing the first cabinet door 31 and the second cabinet door 32 to finally close completely.

[0056] When the first cabinet door 31 is opened to the set opening angle, the self-resetting buffer hinge can push the first cabinet door 31 and the second cabinet door 32 connected to it to fully open. In other words, the user only needs to pull the folding door assembly 3 open to a position close to the open position. When the first cabinet door 31 reaches the set opening angle, the self-resetting buffer hinge can provide the force to continue opening, so that the first cabinet door 31 and the second cabinet door 32 continue to move to the fully open state.

[0057] Through the aforementioned function of the self-resetting buffer hinge, the folding door assembly 3 can obtain auxiliary driving force in both the closing and opening stages, thereby reducing the user's operational burden. Simultaneously, because the self-resetting buffer hinge has a buffering effect, it can reduce the possibility of the cabinet door rapidly colliding with the cabinet body or the door panels colliding with each other, making the cabinet door opening and closing smoother.

[0058] Hinges 33 are disposed between the first cabinet door 31 and the second cabinet door 32. Two hinges 33 may be provided, spaced vertically along the height of the first cabinet door 31 and the second cabinet door 32. The connection between the two hinges 33 improves the hinge strength and folding stability between the first cabinet door 31 and the second cabinet door 32, preventing significant twisting of the second cabinet door 32 relative to the first cabinet door 31.

[0059] The working process of this embodiment is as follows: When the corner cabinet door system is closed, the two sets of folding door assemblies 3 cover the openings of the first cabinet 1 and the second cabinet 2, respectively. The first cabinet door 31 and the second cabinet door 32 in each set of folding door assemblies 3 are in the unfolded state. The first cabinet door 31 is connected to the corresponding cabinet via a hinge 4, and the second cabinet door 32 is connected to the first cabinet door 31 via a hinge 33. The second cabinet doors 32 of the two sets of folding door assemblies 3 are arranged adjacent to each other in the corner area, so that the corner openings of the first cabinet 1 and the second cabinet 2 are jointly closed.

[0060] When a user needs to open the corner cabinet, they can pull either the first door 31 or the second door 32 of one of the folding door components 3. Under the action of external force, the first door 31 rotates relative to the corresponding cabinet body around the hinge 4, and the second door 32 begins to fold relative to the first door 31 under the action of the hinge 33. At the same time, the guide device 5 installed on the second door 32 slides along the corresponding guide rail 6.

[0061] During the sliding process of the guide device 5, the guide wheel 52 is located within the guide groove 61 of the guide rail 6 and moves along the guide groove 61, while the anti-detachment wheel 53 is located outside the guide rail 6 and moves synchronously with the guide wheel 52. The clamping groove 54 formed between the guide wheel 52 and the anti-detachment wheel 53 clamps the groove wall of the guide rail 6, preventing the guide device 5 from detaching from the guide rail 6. As a result, the movement trajectory of the second cabinet door 32 is constrained by the guide rail 6, enabling it to fold smoothly relative to the first cabinet door 31.

[0062] When the first cabinet door 31 is opened to the set opening angle, the self-resetting buffer hinge generates a force that pushes the cabinet door to continue opening, pushing the first cabinet door 31 and the second cabinet door 32 connected to it to continue opening until the folding door assembly 3 reaches the fully open state. At this time, the corresponding opening of the first cabinet 1 or the second cabinet 2 is fully released, and the user can easily access the interior space of the cabinet.

[0063] Because the two sets of folding door components 3 are set to open in opposite directions, users can open the folding door components 3 at the openings of the first cabinet 1 and the second cabinet 2 respectively. When both sets of folding door components 3 are opened, the L-shaped corner area of ​​the first cabinet 1 and the second cabinet 2 can be fully opened, directly exposing the storage space that was originally located deep in the corner. Users can more intuitively observe the position of items inside the corner cabinet and can access and place items inside the corner cabinet from two directions.

[0064] When the user needs to close the cabinet door, the user pushes the folding door assembly 3, which is in the open state. The first cabinet door 31 rotates around the hinge 4 in the closing direction, while the second cabinet door 32 slides in the opposite direction along a predetermined trajectory under the cooperation of the guide device 5 and the guide rail 6, and gradually unfolds relative to the first cabinet door 31. When the first cabinet door 31 is closed to the set closing angle, the self-resetting buffer hinge generates a force to push the cabinet door to continue closing, pushing the first cabinet door 31 and the second cabinet door 32 connected to it to close completely.

[0065] During the closing process, the guide wheel 52 slides in the opposite direction along the guide groove 61, the anti-detachment wheel 53 moves in the opposite direction along the outside of the guide rail 6, and the clamping groove 54 continuously clamps the groove wall of the guide rail 6, so that the second cabinet door 32 remains stable during the unfolding and resetting process. Finally, the first cabinet door 31 and the second cabinet door 32 return to the position covering the corresponding cabinet opening, and the second cabinet doors 32 of the two sets of folding door assemblies 3 are arranged adjacent to each other in the corner area, completing the closing of the corner cabinet door system.

[0066] Through the aforementioned structure and working process, this invention enables the corner cabinet to form openable folding door structures in both intersecting directions. Once the cabinet doors are opened, the interior space of the corner cabinet, especially the deep corner space, is fully exposed, allowing users to retrieve items without having to bend over, lean out, or go around the fixed door panel. Compared to traditional corner cabinets, this invention improves the utilization rate of the interior space, enhances the convenience for users to access items, and, through the cooperation of the guide device 5, guide rail 6, and self-resetting buffer hinge, improves the smoothness, stability, and safety of the cabinet door opening and closing.

[0067] It should be noted that in this embodiment, the first cabinet 1 and the second cabinet 2 can be independent cabinets, or they can be two L-shaped intersecting cabinet parts in an integrated cabinet. The specific dimensions of the folding door assembly 3, the number of door panels, the installation position of the guide rail 6, and the specific form of the guide device 5 can be adaptively adjusted according to the actual cabinet size and usage requirements. As long as the two sets of reverse-opening folding door assemblies 3 described in this invention are used in conjunction with the corresponding guide rail 6 and guide device 5 to achieve a fully openable corner cabinet structure, it should fall within the protection scope of this invention.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. All equivalent substitutions, modifications, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
