Description

Technical Field

[0001] This utility model relates to the field of ghost door technology, and in particular to a ghost door guide wheel mechanism. Background Technology

[0002] Ghost doors, as an innovative door type with a unique floating visual effect, have been increasingly widely used in the field of interior decoration in recent years. With their simple and beautiful appearance, novel and unique design, and space-saving advantages, they are loved by consumers, especially suitable for places with high requirements for spatial aesthetics and functionality, such as modern-style homes and high-end commercial spaces. As people's quality of life continues to improve and their aesthetic concepts become increasingly diversified, higher demands are being placed on the performance and user experience of ghost doors. They are not only required to have good decorative properties, but also to be more convenient and efficient in installation and use to adapt to personalized needs in different scenarios.

[0003] In existing ghost door guide wheel mechanisms, the guide wheels are typically fixed directly to the wall. This fixing method determines the relative position between the guide wheels and the wall after installation, making subsequent adjustments impossible. However, during actual door installation, installation errors are inevitable due to various factors. For example, there may be dimensional deviations during door manufacturing, or inaccurate measurements and positioning at the installation site. These factors can lead to a mismatch between the actual installed door height and the pre-set height of the guide wheels on the wall. In such cases, existing guide wheel mechanisms cannot be easily and effectively adjusted on-site; the guide wheels must be disassembled and reinstalled. This not only increases the complexity and time of installation but may also cause unnecessary damage to the wall, affecting the overall installation quality and aesthetics.

[0004] Meanwhile, the thickness of ghost door bodies is not entirely uniform; different styles and specifications of ghost doors may have significant differences in thickness. Existing ghost door guide wheel mechanisms are often designed and installed with a fixed distance to the wall based on a specific door thickness. This means that existing guide wheel mechanisms cannot adapt well to door thicknesses. If the door thickness is less than the preset thickness of the guide wheel mechanism, the door and guide wheel may not fit tightly, affecting the smoothness and stability of the door's sliding. If the door thickness is greater than the preset value, it may prevent the door from being installed properly, or cause interference between the door and guide wheel after installation, affecting the normal opening and closing of the door, causing great inconvenience to users and limiting the versatility and applicability of ghost doors. Utility Model Content

[0005] The purpose of this utility model is to disclose a guide wheel mechanism for ghost doors. By improving the structural design of the guide wheel mechanism, it is made to have the function of adjustment in two directions. It can be flexibly adjusted according to the actual installation situation and the needs of door bodies of different thicknesses, thereby effectively reducing the assembly difficulty, improving the installation efficiency, and enhancing the adaptability and versatility of ghost doors.

[0006] To achieve the above objectives, this utility model discloses a ghost door guide wheel mechanism, comprising: a base plate, the base plate including a first plate and a second plate, one end of the first plate being perpendicularly connected to one end of the second plate; a first mounting seat, the first mounting seat being slidably sleeved on the first plate and movable along the length direction of the first plate, the first mounting seat being used to fix to a wall; a first fastener, the first fastener being used to lock the first mounting seat relative to the first plate; a second mounting seat, the second mounting seat being slidably sleeved on the second plate and movable along the length direction of the second plate; a second fastener, the second fastener being used to lock the second mounting seat relative to the second plate; and a guide wheel assembly, the guide wheel assembly being mounted on the second mounting seat and used to support and guide the movement of the ghost door; wherein, the length direction of the first plate is parallel to the height direction of the ghost door to achieve adjustment of the installation height of the guide wheel assembly; the length direction of the second plate is perpendicular to the wall to achieve adjustment of the distance between the guide wheel assembly and the wall.

[0007] By adopting the above solution, when the actual installed height of the door does not match the pre-set height of the guide wheels on the wall, simply loosen the first fastener, then adjust the first plate to a suitable position according to the actual height of the door, so that the height of the guide wheel assembly matches the height of the door. Finally, tighten the first fastener again. This avoids damage to the wall caused by repeated disassembly and installation, effectively reducing assembly difficulty, shortening installation time, and improving installation quality. When encountering doors of different thicknesses, the second fastener can be loosened according to the actual thickness of the door, allowing the second mounting base to slide on the second plate. This adjusts the distance between the second mounting base and the wall, thereby changing the distance between the guide wheel assembly and the wall. This allows for good adaptation to doors of different thicknesses, enhancing the versatility and applicability of the ghost door and providing users with a better experience.

[0008] Furthermore, the first mounting base is provided with a first sliding groove, and the first plate is slidably disposed in the first sliding groove; the two side walls of the first sliding groove are provided with first locking holes, and the first fastener passes through the first locking holes and can abut against the side of the first plate; the second mounting base is provided with a second sliding groove, and the second plate is slidably disposed in the second sliding groove; the two side walls of the second sliding groove are provided with second locking holes, and the second fastener passes through the second locking holes and can abut against the side of the second plate.

[0009] By adopting the above scheme, the cooperation between the slide and the plate provides a stable track for sliding adjustment, making the sliding process of the first mounting seat on the first plate and the second mounting seat on the second plate smoother and more precise, reducing shaking and offset during the sliding process. At the same time, it makes the sliding operation of the mounting seats easier, eliminating the need to overcome significant friction or use complex tools, simplifying the adjustment process and improving installation and debugging efficiency. By applying pressure through direct contact between the fasteners and the side of the plate, significant friction is generated, firmly locking the mounting seats and the plate together, effectively preventing the mounting seats from sliding or loosening during the use of the ghost door, ensuring the stability and reliability of the guide wheel mechanism.

[0010] Furthermore, a friction-aiding area is provided on the side of the first plate and / or the side of the second plate, and the length of the friction-aiding area is not less than the maximum sliding distance between the first plate and the second plate.

[0011] By adopting the above solution, the friction auxiliary zone can increase the friction between the plate and the fastener, making the locking between the mounting base and the plate more secure, preventing the guide wheel mechanism from being affected by loosening, and ensuring that the ghost door can stably achieve the levitation effect and smooth sliding.

[0012] Furthermore, the friction-aided area is a corrugated structure formed on the side of the first plate or the second plate.

[0013] By adopting the above scheme, the corrugated structure has multiple peaks and troughs, enabling multi-point contact with the fastener surface when the fastener abuts against the side of the plate. This multi-point contact method makes the friction force distribution more uniform and continuous. Even with slight vibrations or external impacts during use, sufficient friction force can be ensured to maintain the relative position of the mounting base and the plate, improving the anti-interference capability of the guide wheel mechanism. The resistance of the corrugated structure can also prevent the mounting base from sliding too quickly due to inertia during sliding, thus avoiding over-adjustment.

[0014] Furthermore, the friction-assisted area is a groove formed on the side of the first plate or the second plate, and a friction element is embedded in the groove. The friction element has a surface friction coefficient that is greater than that of the substrate.

[0015] By adopting the above solution, the high friction provided by the friction element acts as appropriate resistance during the sliding adjustment of the mounting base, thereby more precisely controlling the sliding distance and position of the mounting base and achieving precise fine-tuning of the ghost door height and the distance between the guide wheel assembly and the wall. Simultaneously, the presence of the friction element generates greater friction than directly pressing against the base plate. This makes the connection between the mounting base and the plate more robust, effectively preventing the mounting base from loosening due to the force generated by the door's movement during use, ensuring that the guide wheel mechanism always stably supports and guides the ghost door's sliding, guaranteeing its levitation effect and smooth operation.

[0016] Furthermore, the friction member has a first engaging portion and a second engaging portion disposed opposite to each other, the first engaging portion and the second engaging portion respectively abutting against both sides of the groove.

[0017] By adopting the above-described scheme, precise positioning is provided for the installation of the friction component within the groove. During the process of embedding the friction component into the groove, the operator can quickly and accurately place the friction component in the appropriate position based on the fit between the locking part and the sidewall of the groove. During embedding, the locking part and the sidewall of the groove mutually constrain each other, ensuring that the friction component can only be installed along a specific direction and position. Once installed in place, the locking part will tightly abut against both sides of the groove, preventing displacement or rotation of the friction component during subsequent use or adjustment, thus ensuring a stable connection between the friction component and the groove.

[0018] Furthermore, the second mounting base is also provided with a toggle block for triggering damping, and the friction element is used to provide a buffering force when the toggle block is subjected to force.

[0019] By adopting the above solution, when the door reaches the open state, the actuating block can trigger the damping of the door structure, thereby achieving a buffering and deceleration effect on the door and reducing impact noise. The presence of friction components can buffer the impact of the actuating block, thereby reducing the impact force and impact noise caused by repeated contact of the actuating block.

[0020] Furthermore, the first plate has a first waist-shaped hole extending along its length, and the first mounting base has a first threaded hole corresponding to the position of the first waist-shaped hole; the second plate has a second waist-shaped hole extending along its length, and the second mounting base has a second threaded hole corresponding to the position of the second waist-shaped hole.

[0021] By adopting the above scheme, the waist-shaped hole allows the mounting base to adjust its angle and position within a certain range to better adapt to changes in the mounting surface, enabling the guide wheel mechanism to be stably installed on various complex surfaces, thus improving the applicability and stability of the structure.

[0022] Furthermore, the bottom of the first groove is provided with an outwardly protruding first rib; and / or the bottom of the second groove is provided with an outwardly protruding second rib.

[0023] By adopting the above scheme, the first and second ribs protrude outwards, which can accurately define the effective depth of the groove, avoiding the up-and-down swaying of the sliding parts caused by inconsistent groove depth, and improving the smoothness and accuracy of sliding. The outwardly protruding ribs increase the moment of inertia of the groove bottom section, significantly improving the bending stiffness of the groove. When subjected to external loads or the force of the sliding parts, the groove is less prone to bending deformation, maintaining its original shape and size, providing stable support for the sliding parts, and thus ensuring the reliability and stability of the entire sliding system.

[0024] Furthermore, the second mounting base has a guide wheel mounting waist-shaped hole, the length direction of which is parallel to the movement direction of the ghost door; the guide wheel assembly is mounted in the guide wheel mounting waist-shaped hole via a guide wheel shaft, and its position can be adjusted along its length direction; at least two guide wheel assemblies are provided in the guide wheel mounting waist-shaped hole.

[0025] By adopting the above scheme, setting at least two guide wheel groups can distribute the load-bearing pressure on the mounting base and track during the movement of the ghost door, avoiding the aggravated wear or damage of a single guide wheel group due to excessive force, and improving the load-bearing capacity and reliability of the entire guide wheel system.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When a height mismatch occurs, simply loosen the first fastener, adjust the position of the first plate according to the actual height of the door, ensuring the guide wheel assembly is at the same height as the door, and then tighten the first fastener. This avoids damage to the wall caused by repeated disassembly and installation, effectively reducing assembly difficulty, shortening installation time, and improving installation quality. If the initial distance between the guide wheel assembly and the wall is found to be unsuitable, the distance can be changed by loosening the second fastener and moving the second mounting base, eliminating the need for complex reinstallation operations and further reducing the complexity and difficulty of assembly. 2. When encountering doors of varying thicknesses, the second fastener can be loosened according to the actual thickness of the door, allowing the second mounting base to slide on the second plate. This adjusts the distance between the second mounting base and the wall, thereby changing the distance between the guide wheel assembly and the wall. In this way, regardless of whether the door thickness is less than or greater than the preset value, it can tightly cooperate with the guide wheel assembly, ensuring smooth and stable door sliding and normal opening and closing, greatly enhancing the versatility and applicability of the ghost door. 3. The guide wheel mechanism allows for position adjustment without disassembling the guide wheels through sliding adjustment, greatly simplifying the installation process, improving installation efficiency, and reducing the labor intensity of installers. By precisely adjusting the position of the guide wheel assembly to perfectly match the height and thickness of the door, it ensures that the ghost door remains stable and smooth during movement, reducing shaking and jamming, providing users with a more stable and reliable user experience, avoiding damage to the wall caused by repeated disassembly and installation, and maintaining the integrity and aesthetics of the wall surface.

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

[0036] This utility model is referenced. Figures 1 to 4As shown, a ghost door guide wheel mechanism is disclosed. This mechanism mainly includes a base plate 1, a first mounting base 2, a first fastener 3, a second mounting base 4, a second fastener 5, and a guide wheel assembly 6. The base plate 1 has an overall L-shaped structure and is integrally formed or fixedly connected by a first plate 11 and a second plate 12. One end of the first plate 11 is perpendicularly connected to one end of the second plate 12, so that the side surface of the base plate 1 forms an L-shaped profile. The first mounting base 2 is slidably fitted onto the first plate 11 through a first groove 21 opened inside it, and can move along the length direction of the first plate 11. The first mounting base 2 is used to fix to the wall. The first fastener 3 is used to lock the first mounting base 2 relative to the first plate 11 after adjustment. Similarly, the second mounting base 4 is slidably fitted onto the second plate 12 through a second groove 41 opened inside it, and can move along the length direction of the second plate 12. The second fastener 5 is used to lock the second mounting base 4 relative to the second plate 12. The guide wheel assembly 6 is mounted on the second mounting base 4 via the guide wheel shaft 61, and is used to support and guide the ghost door to move on the track.

[0037] During installation, the length of the first plate 11 should be parallel to the height of the ghost door, i.e., vertical. The installation height of the guide wheel assembly 6 can be adjusted by sliding the first mounting base 2. At the same time, the length of the second plate 12 should be perpendicular to the wall. The distance between the guide wheel assembly 6 and the wall can be adjusted by sliding the second mounting base 4, thus adapting to door bodies of different thicknesses.

[0038] In some embodiments, the sliding engagement and locking method between the mounting base and the substrate can be further defined. Specifically, the first mounting base 2 is provided with a first sliding groove 21, and the first plate 11 is slidably disposed within the first sliding groove 21. First locking holes 22 are formed on both side walls of the first sliding groove 21. The first fastener 3 passes through the first locking holes 22 and can be tightened, so that its end abuts against the side of the first plate 11, achieving locking through friction. Similarly, the second mounting base 4 is provided with a second sliding groove 41, and the second plate 12 is slidably disposed within the second sliding groove 41. Second locking holes 42 are formed on both side walls of the second sliding groove 41. The second fastener 5 passes through the second locking holes 42 and can be tightened, so that its end abuts against the side of the second plate 12. This structure provides a stable track for sliding adjustment and makes the locking operation simple and reliable.

[0039] In this embodiment 1, the slide structure has been improved to enhance its anti-disengagement capability during sliding. Specifically, a first limiting lip 23 extends inward from both sides of the opening of the first slide 21. Similarly, a second limiting lip 43 extends inward from both sides of the opening of the second slide 41. These inwardly protruding lips can partially cover the opening, preventing the first plate 11 or the second plate 12 from accidentally disengaging from the slide during sliding or under external force, thus improving the safety and reliability of the mechanism.

[0040] In some embodiments, to enhance the reliability of locking, friction-aiding areas 8 are provided on the sides of the first plate 11 and / or the second plate 12. The length of the friction-aiding area 8 is not less than the maximum distance that the first plate 11 and the second plate 12 can slide in their corresponding grooves, ensuring effective friction assistance throughout the entire adjustment range.

[0041] Specifically, in this embodiment 1, the friction-aiding area 8 located on the side of the first plate 11, i.e., the side constituting the L-shaped structure, is configured as a corrugated structure 111 formed on that side, such as... Figure 3 As shown. The corrugated structure 111 has continuous crests and troughs, which can generate a uniform and strong frictional force when the first fastener 3 is tightened. The shape of the crests and troughs is particularly effective in preventing the door from sliding down due to its own weight. At the same time, the friction auxiliary area 8 located on the side of the second plate 12 is configured as a groove 121 opened on this side, and the friction element 7 is embedded in the groove 121, such as... Figure 3-4 As shown. The surface friction coefficient of the friction element 7 is greater than that of the substrate 1. The substrate 1 is usually made of metal, such as aluminum profile or steel, while the friction element 7 can be made of engineering plastics, rubber or composite materials, etc.

[0042] In some embodiments, to further improve the installation stability of the friction member 7, the friction member 7 is provided with a first engaging portion 71 and a second engaging portion 72 disposed opposite to each other. When the friction member 7 is embedded in the groove 121, the first engaging portion 71 and the second engaging portion 72 elastically or with interference fit against the two side walls of the groove 121, respectively. This engaging structure not only facilitates installation and positioning but also effectively prevents the friction member 7 from loosening from the groove 121 during use.

[0043] In this embodiment 1, a toggle block 9 is also provided on the second mounting base 4. It should be noted that the friction element can be made of soft rubber. When the ghost door moves to a fully open or closed state, the toggle block 9 triggers the damping mechanism, first achieving buffered deceleration of the door. Simultaneously, the friction element 7 further mitigates the rigid impact on the toggle block 9 upon contact with the damping mechanism, thereby preventing damage to the base plate 1 or the generation of abnormal noise from the impact force, playing a crucial role in buffering and noise reduction. The friction element 7 can both increase friction and provide buffering force, reducing collision damage and noise impact.

[0044] It should be noted that the configuration of the friction auxiliary area 8 in this embodiment 1, namely, the corrugated structure 111 for the first plate and the groove 121 with friction element for the second plate, is only a preferred example. In other embodiments, it can be varied as needed. For example, the side of the first plate 11 can also adopt the groove 121 structure with friction element; or the side of the second plate 12 can also adopt the corrugated structure 111; or both the side of the first plate 11 and the second plate 12 adopt the corrugated structure 111; or both adopt the groove 121 structure with friction element. These variations all fall within the protection scope of this utility model.

[0045] In this embodiment 1, an auxiliary installation structure can also be added to improve installation flexibility. Specifically, the first plate 11 has a first oblong hole 112 extending along its length. The first mounting base 2 has a first threaded hole 25 corresponding to the position of the first oblong hole 112. By using bolts or other mounting parts to pass through the first oblong hole 112 and connect to the first threaded hole 25, the position of the first mounting base 2 on the first plate 11 can be finely adjusted before final locking.

[0046] Similarly, the second plate 12 has a second oblong hole 122 extending along its length. The second mounting base 4 has a second threaded hole 46 corresponding to the position of the second oblong hole 122. By connecting the second mounting base 4 to the second threaded hole 46 through bolts or other mounting parts, the position of the second mounting base 4 on the second plate 12 can be finely adjusted.

[0047] In some embodiments, a first rib 24 protruding outward may be provided at the bottom of the first slide groove 21. And / or, a second rib 44 protruding outward may be provided at the bottom of the second slide groove 41. The first rib 24 and the second rib 44 can act as reinforcing ribs, effectively increasing the bending stiffness of the bottom of the slide groove, making it less prone to deformation under load, ensuring the accuracy of the sliding fit and the stability of the entire mechanism. At the same time, the first rib 24 and the second rib 44 effectively reduce the distance between the bottom of the first slide groove 21 and the first limiting lip 23, and the distance between the second slide groove 41 and the second limiting lip 43, thereby limiting the sliding stability of the substrate in the first mounting base 2 and the second mounting base 4, and avoiding sliding wobbling.

[0048] In some embodiments, the installation method of the guide wheel assembly on the second mounting base can be optimized. Specifically, a guide wheel mounting slot 45 is provided on the second mounting base 4, the length direction of which is parallel to the movement direction of the ghost door, i.e., horizontal. The guide wheel assembly 6 includes a guide wheel body 62 and a guide wheel shaft 61, and the guide wheel body 62 is mounted in the guide wheel mounting slot 45 through the guide wheel shaft 61. By loosening the guide wheel shaft 61, the horizontal position of the guide wheel assembly 6 can be adjusted along the length direction of the guide wheel mounting slot 45. Preferably, at least two guide wheel assemblies 6 are provided in the guide wheel mounting slot 45 to distribute the load and improve the smoothness of operation and the load-bearing capacity of the mechanism.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
