Description

Technical Field

[0001] The present invention relates to the technical field of doors, and in particular to a linkage component and a linkage door. Background Art

[0002] In the field of doors and windows, whether it is a cabinet door, shower door, wardrobe door, room door or window, there is a flat opening movable structure. With the development of this flat opening movable door and window technology, there are already products with multiple movable doors and windows in this industry, and its basic structure includes two or more movable doors and windows with mutually offset moving paths. Take the shower door composed of two movable doors as an example. During the closing process, the user pushes or pulls the first movable door so that the first movable door moves to abut against the second movable door, and further pulls the first movable door so that the first movable door drives the second movable door to move synchronously, until the first movable door and the second movable door finally move to the closed position; conversely, the door opening process is also through the first movable door moving first and then abutting against the second movable door until both movable doors move to the open position.

[0003] Obviously, the two movable doors move one after the other and cannot move synchronously. The disadvantage is that there is impact between the two movable doors. Especially when the user opens or closes the door with great force, the two movable doors are easily damaged due to collision. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art to at least some extent: to provide a linkage assembly which can realize the linkage of multiple external movable parts, and because of the small number of parts, the cost is low and the space occupied is small.

[0005] To this end, an object of the present invention is to propose a linkage assembly, which includes a fixed rack for connecting to an external load-bearing component and a movable rack arranged parallel to the fixed rack, a movable gear is provided between the fixed rack and the movable rack, the movable gear is respectively meshed with the movable rack and the fixed rack to make the movable rack and the movable gear linked, and the movable rack and the movable gear are respectively installed with connecting parts for connecting to their corresponding external movable components.

[0006] The movable gear includes a wheel body, and a plurality of teeth are arranged on the outer circumferential surface of the wheel body. All the teeth are arranged at intervals along the circumference of the wheel body to form a gear ring that matches the movable rack and the fixed rack. Support surfaces are respectively arranged on the outer sides of the gear ring along the axial direction on the outer circumferential surface of the wheel body.

[0007] The above technical solution has the following advantages or beneficial effects: the linkage between the movable gear and the movable rack is achieved through the meshing between the two, so that a linkage can be formed between an external movable part connected to the connecting part on the movable gear and another external movable part connected to the connecting part on the movable rack.

[0008] The present invention aims to solve one of the technical problems in the related art to at least a certain extent: to provide a linkage door, in which two associated movable doors can be linked to each other, thereby reducing the damage caused by the mutual collision between the two movable doors, while occupying a small space, being easy to install on the guide rail, and having a stable linkage structure and not prone to failure.

[0009] To this end, an object of the present invention is to propose a linkage door, which includes a guide rail and at least two movable doors, each movable door is respectively installed on the guide rail and can translate along the length direction of the guide rail, and is characterized in that: the linkage door also includes at least one linkage component, the fixed rack in the linkage component is fixedly connected to the guide rail, the movable rack in the linkage component is connected to the corresponding one of the movable doors, the movable gear in the linkage component is connected to the corresponding other movable door and the movable gear rotates around its own axis to cooperate with the corresponding movable door.

[0010] The guide rail comprises an upper guide rail and a lower guide rail;

[0012] Or there are one or more linkage components, and all linkage components are arranged on the lower guide rail;

[0013] Or there are multiple linkage components, and at least one linkage component is respectively provided on the upper guide rail and the lower guide rail.

[0014] The movable gear includes a wheel body, and a plurality of teeth are arranged on the outer circumferential surface of the wheel body. All the teeth are arranged at intervals along the circumference of the wheel body to form a gear ring that matches the movable rack and the fixed rack. Support surfaces are respectively provided on the outer sides of the gear ring on the outer circumferential surface of the wheel body, and a bearing surface matching the support surface is provided on the guide rail. When the support surface on the movable gear abuts against the bearing surface on the guide rail, the gear ring meshes with the fixed rack.

[0015] Each movable door is provided with one or more rollers, which are connected to the corresponding movable door and rollingly cooperate with the guide groove on the guide rail; the guide groove is inscribed at the position corresponding to the movable gear to form an installation space for accommodating a fixed rack, and the fixed rack is fixed in the installation space.

[0016] The inner wall of the guide groove located at the position where the fixed rack is located is the bearing surface.

[0017] The installation space extends along the length direction of the guide rail to the end surface of the guide rail to form an installation opening for the fixed rack to be inserted into the installation space.

[0018] The installation space includes an accommodating cavity located below the guide groove, the accommodating cavity and the guide groove are connected by a connecting channel, the width of the connecting channel is smaller than the width of the fixed rack located in the accommodating cavity, and the accommodating cavity extends along the length direction of the guide rail to the end face that passes through the guide rail to form an installation opening for the fixed rack to be inserted into the accommodating cavity.

[0020] The above technical scheme has the following advantages or beneficial effects: first, the multiple movable doors on the linkage door can realize the linkage of the opening and closing process through the setting of the linkage component, so as to achieve synchronous movement; secondly, the linkage component consists of few parts and the overall volume is small, so it is convenient to install on the guide rail and the cost is low; finally, through the design of the supporting surface on the movable gear, the movable gear can be rolled in the guide groove and can be meshed with the fixed rack in the guide groove. The advantages of this structural design are: 1) The guide groove and the fixed rack are combined in the same spatial position, and the overall space occupied by the guide rail is small; 2) The supporting force of the movable gear mainly relies on the mutual abutment between the supporting surface and the bearing surface where the inner wall of the guide groove is located to form support, thereby reducing the force between the gear ring of the movable gear and the fixed rack, which not only reduces the resistance on the gear ring, making the meshing process smoother, but also reduces the wear between the gear ring and the fixed rack, thereby improving the service life.

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The linkage assembly and the linkage door according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Linkage components of embodiment 1:

[0037] The present invention provides a linkage component, such as Figure 7-9As shown, it includes a fixed rack 1 connected to an external load-bearing component 100 and arranged in a horizontal direction, and a movable rack 2 arranged above the fixed rack 1 and parallel to the fixed rack 1, a movable gear 3 is arranged between the fixed rack 1 and the movable rack 2, the upper position of the movable gear 3 is meshed with the movable rack 2, and the lower position of the movable gear 3 is meshed with the fixed rack 1, thereby forming a linkage between the movable rack 2 and the movable gear 3, the so-called linkage means that when the movable rack 2 is subjected to external force and moves along its own axial position, the movable gear 3 also moves with the movement of the movable rack 2 and the movable gear 3 also rotates circumferentially around its own axis at the same time, anyway, the movable gear 3 can also drive the movable rack 2 to translate axially when subjected to external force, so a linkage is formed between the movable rack 2 and the movable gear 3, and the movable rack 2 and the movable gear 3 are respectively installed with connecting parts 300 for connecting to their respective corresponding external movable components 200.

[0038] The above-mentioned external load-bearing component 100 refers to an external component that can be used to install a linkage component, such as a door beam, a door guide rail, a wall, a window frame, and any other load-bearing component that can be installed with a linkage component to achieve the opening and closing of a door or window. All of them belong to the external load-bearing component 100.

[0039] The external movable parts 200 can be sliding doors, cabinet doors, sliding windows, etc., which can be opened and closed by moving. Therefore, the connectors 300 in the linkage assembly of the present invention are respectively connected to multiple external movable parts 200, thereby realizing linkage between multiple external movable parts 200.

[0040] As a preferred embodiment, the connecting member 300 includes a first connecting member 301 and a second connecting member 302 ; wherein the first connecting member 301 is fixedly connected to the movable rack 2 ; wherein the second connecting member 302 is rotationally matched with the movable gear 3 .

[0041] Specifically, Fig. 9 The first connecting member 301 shown includes a connecting piece 3011 and a first mounting member 3012 for connecting to the external movable component 200, one end of the connecting piece is connected to the movable rack 2, and the other end is connected to the first mounting member 3012. The second connecting member 302 includes a connecting shaft 3021 and a second mounting member 3022 for connecting to the external movable component 200, both ends of the connecting shaft 3021 are connected to the movable gear 3 and the second mounting member 3022 respectively, and at least one of the two ends of the connecting shaft 3021 is rotatably matched with the movable gear 3 or the second mounting member 3022.

[0042] As a preferred embodiment, Figure 8 and 9The movable gear 3 shown includes a wheel body 3.1, and a plurality of teeth are arranged on the outer circumferential surface of the wheel body 3.1. All the teeth are arranged at intervals along the circumference of the wheel body 3.1 to form a gear ring 3.2 that cooperates with the movable rack 2 and the fixed rack 1. Support surfaces 3.3 are respectively provided on the outer circumferential surface of the wheel body 3.1 at positions axially located on both sides of the gear ring 3.2.

[0043] Further, as shown in the figure, the support surface 3.3 is located outside the gear ring 3.2 in the axial direction, and the support surface 3.3 is a conical surface formed by inscribed on the outer circumferential surface of the gear body 3.1. It should be emphasized that the support surface 3.3 in this embodiment is different from the chamfered surface of the component, and the functions of the two are completely different. The support surface 3.3 in this embodiment is used to support the entire movable gear 3.1 to reduce the force on the gear ring 3.2, thereby protecting the gear ring 3.2.

[0044] Embodiment 2 of the linkage door:

[0045] The present invention provides a linkage door, such as Figure 1-3 The structure shown in the figure includes two left and right door frames 102, a guide rail 101 installed on the door frames 102, and two or more movable doors 201 arranged between the two door frames 102 and capable of translating along the length direction of the guide rail 101. Each movable door 201 is individually installed on the guide rail 101. It is characterized in that the linkage door further includes a linkage mechanism for driving at least two movable doors 201 of all movable doors 201 to be linked. That is, through the linkage mechanism on the linkage door, all movable doors 201 are linked, or two movable doors 201 of multiple movable doors 201 are linked, or two movable doors 201 of four or more movable doors 201 form a group, and the two movable doors 201 in the same group are linked.

[0046] Embodiment three:

[0047] The basic structure is the same as that of the second embodiment, except that: there are two movable doors 201, and the two movable doors 201 are staggered along their thickness direction so that the moving paths of the two movable doors 201 are staggered. The linkage mechanism includes a chain (not shown in the figure) and a movable pulley (not shown in the figure). The movable pulley is connected to one of the movable doors 201, one end of the chain is fixedly connected to the door frame or the guide rail, and the other end of the chain is wound around the outside of the movable pulley and fixedly connected to the other movable door 201. A tension spring is provided between the movable pulley and the guide rail, and the two ends of the tension spring are respectively connected to the movable pulley and the guide rail, and the directions of the forces applied to the movable pulley by the tension spring and the chain are opposite.

[0048] Preferably, when the number of movable doors 201 is more than two, the number of movable pulleys can be increased on the basis of the linkage mechanism in the present embodiment, and the linkage of multiple movable pulleys can be realized through the same chain, and the multiple movable pulleys are respectively connected to the corresponding movable doors 201;

[0049] Preferably, when the number of movable doors 201 is more than two, the number of chains and movable pulleys can be increased on the basis of the above-mentioned linkage mechanism in this embodiment, and the linkage between two adjacent movable doors 201 among the multiple movable doors 201 is achieved through their respective corresponding chains and movable pulleys.

[0050] The linkage mechanism in this embodiment, which is formed by the cooperation of the chain and the movable pulley, has the advantage that as the number of movable doors increases or decreases, only movable pulleys need to be added. Therefore, for the structure of multiple movable doors 201, the linkage mechanism using the chain structure is more convenient to set up; the disadvantage is that there may be slipping, loosening, chain breakage, and jamming of the movable pulley between the chain and the movable pulley, so the stability of the overall linkage mechanism is poor, especially when used in a shower room, the humid environment may easily cause the chain or the movable pulley to rust or be attached with hair, resulting in failure of the overall linkage mechanism.

[0051] Embodiment 4:

[0052] The basic structure is the same as that of the second embodiment, except that: there are two movable doors 201, and the two movable doors 201 are staggered along their thickness direction so that the moving paths of the two movable doors 201 are staggered. The linkage mechanism includes a pulley (not shown in the figure) and a friction plate (not shown in the figure). Each movable door 201 rolls with the guide rail 101 through its own pulley. The friction plate is fixed on one of the movable doors 201 and the friction plate abuts against the top of the pulley on the other movable door 201, so that the pulley abutting against the friction plate drives the movable door 201 connected to the pulley to move during the rolling process, and at the same time drives the friction plate to move through the friction force between the pulley and the friction plate, and then drives the movable door 201 connected to the friction plate to move through the friction plate, and finally realizes the linkage between the two movable doors 201.

[0053] Preferably, when the number of movable doors 201 is more than two, the multiple movable doors 201 are arranged in sequence, and friction plates are provided between two adjacent movable doors 201. The linkage between the two adjacent movable doors 201 is achieved through their respective friction plates, and finally the linkage between all or part of the movable doors 201 is achieved through multiple friction plates.

[0054] The advantage of this embodiment is that it has a simple structure. Its linkage mechanism only needs one friction plate. By abutting the friction plate against the upper part of the pulley on the adjacent movable door, the two movable doors can be driven to link up through the friction between the friction plate and the pulley. However, its disadvantage is that since the friction plate and the pulley are linked by the friction generated by the abutment, the pulley and the friction plate are likely to slip when the resistance is large. For example, one of the movable doors is blocked, resulting in increased resistance, or with a long period of practical use, the movable door or guide rail has a certain deformation, resulting in increased pulley sliding resistance, or in a specific use environment, such as when used in a shower room, moist pollutants or hair entanglement cause increased sliding resistance between the pulley and the guide rail, etc. Therefore, the pulley and the friction plate in this embodiment are prone to failure, and the stability of the linkage effect is poor.

[0055] Embodiment five:

[0056] The basic structure is the same as that of the second embodiment, except that: there are two movable doors 201, and the linkage mechanism is a linkage assembly, which includes a fixed rack 1 fixedly connected to the guide rail; a movable rack 2 connected to the corresponding first movable door 201; a movable gear 3 connected to the corresponding second movable door 201 and the movable gear 3 rotates around its own axis to cooperate with the second movable door 201; the movable gear 3 is arranged between the fixed rack 1 and the movable rack 2, and the movable gear 3 is respectively engaged with the fixed rack 1 and the movable rack 2.

[0057] Embodiment six:

[0058] The basic structure is the same as that of the fifth embodiment, except that: the number of movable doors 201 is more than two, the linkage mechanism includes no less than M linkage components, and any linkage component is connected to the corresponding two movable doors 201, so that the two movable doors 201 are linked; wherein M=the number of movable doors 201-1. The linkage component can realize the linkage between two adjacent movable doors 201, and when the number of movable doors 201 gradually increases from two, in order to realize the linkage of all movable doors 201, a linkage component in this embodiment can be used between each two adjacent movable doors 201 in the movable doors 201 arranged in sequence to realize the linkage of multiple movable doors.

[0059] Of course, as a preferred embodiment, in order to ensure the effectiveness of the linkage, the number of linkage components provided between the two movable doors 201 is not limited to one as defined in the above embodiment, and may also be multiple. Therefore, using one linkage component or multiple linkage components between two adjacent movable doors 201, and providing linkage components between any two adjacent movable doors 201 or providing linkage components between some two adjacent movable doors 201 are all arbitrary choices made based on the structure of the linkage components in this embodiment and actual needs, and should all fall within the protection scope of the present invention application.

[0060] Embodiment seven:

[0061] The basic structure is the same as that of the fifth embodiment, except that: Figure 5 and 6 As shown, the movable rack 2 is connected to the corresponding first movable door 201 through a first connecting member 301, and a second connecting member 302 is provided between the movable gear 3 and the corresponding second movable door 201, one end of the second connecting member 302 is connected to the corresponding movable door 201, and the other end of the second connecting member 302 is rotationally matched with the movable gear 3.

[0062] Preferably, the second connecting member 302 includes a connecting shaft 3021 and a second mounting member 3022, and both ends of the connecting shaft 3021 are connected to the movable gear 3 and the second mounting member, respectively, and at least one of the two ends of the connecting shaft 3021 is rotationally matched with the movable gear 3 or the second mounting member 3022. Specifically, as shown in the figure, one end of the connecting shaft 3021 is fixedly connected to the second mounting member 3022, and the other end of the connecting shaft 3021 penetrates into the position where the central axis of the movable gear 3 is located and is rotationally matched with the movable gear 3 through a bearing.

[0063] Embodiment eight:

[0064] The basic structure is the same as that of the second embodiment, except that: the guide rail 101 includes an upper guide rail 101-1 and a lower guide rail 101-2, and the linkage mechanisms are all arranged on the upper guide rail 101-1; or the linkage mechanisms are all arranged on the lower guide rail 101-2; or the upper guide rail 101-1 and the lower guide rail 101-2 are respectively provided with linkage mechanisms.

[0065] Embodiment nine:

[0066] The basic structure is the same as that of the eighth embodiment, except that: the linkage mechanism includes no less than M linkage components, and any one linkage component is connected to the corresponding two movable doors 201 so that the two movable doors 201 are linked; wherein M=the number of movable doors 201-1; the linkage component includes a fixed rack 1, which is fixedly connected to the guide rail 101; a movable rack 2, which is connected to the corresponding one of the movable doors 201; a movable gear 3, which is connected to the other corresponding movable door 201 and the movable gear 3 rotates around its own axis to cooperate with the corresponding movable door 201; the movable gear 3 is arranged between the fixed rack 1 and the movable rack 2, and the movable gear 3 is respectively meshed with the fixed rack 1 and the movable rack 2.

[0067] Embodiment ten:

[0068] The basic structure is the same as that of the fifth embodiment and the ninth embodiment, except that: the movable gear 3 in the linkage assembly includes a wheel body 3.1, and a plurality of teeth are arranged on the outer circumferential surface of the wheel body 3.1. All the teeth are arranged at intervals along the circumference of the wheel body 3.1 to form a ring gear 3.2 that matches the movable rack 2 and the fixed rack 1. The outer circumferential surface of the wheel body 3.1 is provided with support surfaces 3.3 extending in the circumferential direction at positions on both sides of the ring gear 3.2. The support surfaces 3.3 are axially exposed outside the ring gear 3.2, and a bearing surface that matches the support surface 3.3 is provided on the guide rail. When the support surface 3.3 on the movable gear 3 abuts against the bearing surface on the guide rail, the ring gear 3.2 meshes with the fixed rack 1.

[0069] Embodiment eleven:

[0070] The basic structure is the same as that of the tenth embodiment, except that each movable door 201 is provided with one or more rollers 202, and the rollers 202 are connected to the corresponding movable door 201 and the rollers 202 are rollingly engaged with the guide grooves 1012 on the guide rail 101, thereby realizing the movement of each movable door 201 through the rolling engagement between the rollers 202 and the guide grooves 1012.

[0071] Embodiment 12:

[0072] The basic structure is the same as that of the eleventh embodiment, except that: the guide groove 1012 is inscribed at a position corresponding to the movable gear 3 to form an installation space for accommodating the fixed rack 1, and the fixed rack 1 is fixed in the installation space.

[0073] Preferably, the guide groove 1012 is a V-shaped groove, and the two opposite inclined surfaces of the guide groove 1012 extend to the position of the fixed rack 1 and serve as the bearing surface 1011 that abuts against the supporting surface 3 . 3 on the movable gear 3 .

[0074] Embodiment 13:

[0075] The basic structure is the same as that of the twelfth embodiment, except that: in order to facilitate the installation between the fixed rack 1 and the guide rail 101, the installation space preferably extends along the length direction of the guide rail to the end surface of the guide rail 101 to form an installation opening for inserting the fixed rack 1 into the installation space. Thus, the fixed rack 1 can be installed along the length direction of the guide rail 101 through the installation opening.

[0076] Embodiment 14:

[0077] The basic structure is the same as that of Example thirteen, with the difference being that the installation space includes a accommodating cavity 1013 located below the guide groove 1012, the accommodating cavity 1013 is connected to the guide groove 1012 via a connecting channel 1014, the width of the connecting channel 1014 is smaller than the width of the fixed rack 1 located in the accommodating cavity 1013, and the accommodating cavity 1013 extends along the length direction of the guide rail 101 to the end face that passes through the guide rail 101 to form an installation opening for the fixed rack 1 to be inserted into the accommodating cavity 1013.

[0078] Preferably, in order to enable the fixed rack 1 to be inserted from the installation port, the size of the accommodating cavity 1013 needs to be larger than the size of the fixed rack 1, so as to facilitate the installation of the fixed rack 1. However, when the fixed rack 1 is axially installed in place, the size of the accommodating cavity 1013 is larger than the fixed rack 1, which will cause the fixed rack 1 to shake to a certain extent in the accommodating cavity 1013. In order to limit the fixed rack 1, a tensioning strip 1015 is provided in the accommodating cavity 1013 on the side of the fixed rack 1 away from the connecting channel 1014. The tensioning strip 1015 respectively abuts against the inner surface of the accommodating cavity 1013 and the fixed rack 1, so that the fixed rack 1 is tightly attached to the connecting channel 1014.

[0079] Preferably, since the size of the fixed rack 1 is often smaller than the length of the entire guide rail 101, the installation space for installing the fixed rack 1 is only located at one end of the middle position of the guide rail 101. If the accommodating cavity 1013 and the connecting channel 1014 are both extended axially to pass through the guide rail 101 in order to meet the requirement of axial installation of the fixed rack 1, the strength of the guide rail 101 will inevitably be reduced. Therefore, the connecting channel 1014 is not formed by partial hole rotation to increase the strength of the guide rail 101, thereby retaining the integrity of the rest of the guide rail 101. However, after the connecting channel 1014 is drilled, the dimensional accuracy of the guide groove 1012 will be destroyed due to the force of processing. In order to meet the needs of this technical problem, this embodiment of the present invention application provides a preferred solution: a reserved groove is provided at the bottom of the guide groove 1012, and a notch 1016 is provided on the side wall of the reserved groove. The notch 1016 extends along the length direction of the guide groove 1012 to form a long strip structure, and part or all of the bottom of the reserved groove is inscribed to form a connecting channel 1014 connected to the accommodating cavity 1013. Therefore, when processing the connecting channel 1014, the deformation caused by the processing will be blocked at the notch 1016, thereby maintaining the dimensional accuracy of the inner wall of the upper groove of the guide groove 1012, that is, improving the dimensional accuracy of the bearing surface 1011 on the guide groove 1012, and finally achieving the assembly accuracy of the movable gear 3 and the roller 202 with the guide groove 1012.
