Description

Technical Field

[0001] The present application relates to the field of furniture technology, and in particular to a deformable dining table. Background Art

[0002] The dining table is one of the essential furniture in a family. Most traditional dining tables have a fixed tabletop structure and the size of the tabletop cannot be changed. When the space where the dining table is placed or the occasion of use changes, such as moving from a large room to a small room, the number of diners changes, or the table is used or idle alternately, it will cause many inconveniences.

[0003] There are roughly two types of dining tables with changeable tabletop sizes on the market. One is a foldable dining table top with hinges around the tabletop. However, the hinges are located around the tabletop, which destroys the overall appearance of the tabletop. The hinges will have gaps and rust after a period of use, resulting in an unsmooth folding action. The other is a dining table top that is stretched and folded at both ends. It is tightened with a tension spring. Since the closure of the movable tabletop requires overcoming the tension of the tension spring, the spring tension is about 100N to facilitate the closure of the movable tabletop. This results in poor load-bearing capacity of the movable tabletop, and it will automatically retract under a certain forward pressure, posing a risk of injury.

[0004] Therefore, it is necessary to design a transformable dining table to improve space utilization. Summary of the invention

[0005] In order to solve the above technical problems, the present application provides a deformable dining table, which can improve space utilization, has a stable structure, and has the advantages of easy and safe operation.

[0006] The application provides a deformable dining table, comprising a fixed table top and a fixed frame connected to the fixed table top, and also comprising a movable table top, wherein the movable table top is connected to a lifting mechanism, and the lifting channel is slidably connected to the fixed frame through a sliding mechanism, and a storage space is provided between the fixed table top and the fixed frame;

[0007] Among them, when the lifting mechanism drives the movable table to move close to the sliding mechanism and the sliding mechanism moves close to the fixed frame, the movable table is located in the storage space and is in a storage state; when the sliding mechanism moves away from the fixed frame and the lifting mechanism drives the movable table to move away from the sliding mechanism and extend out of the outer end surface of the fixed table, and the upper surface of the movable table is level with the upper surface of the fixed table, the movable table is in an extended state.

[0008] By adopting the above technical solution, the sliding mechanism is slidably connected to the fixed frame, and the lifting mechanism is fixed on the sliding mechanism and can drive the movable table board to move up and down. Thus, the sliding mechanism can drive the lifting mechanism and the movable table board to slide relative to the fixed frame, and the lifting mechanism can drive the movable table board to move up and down relative to the sliding mechanism. Driven by the sliding mechanism and the lifting mechanism, the movable table board has two usage states: a storage state and an extended state. When the movable table board is in the storage state, the movable table board is completely hidden under the fixed table board, and the length and width dimensions of the dining table are the external dimensions of the fixed table board. This state can reduce the occupied space of the dining table. When the movable table board is in the extended state, the movable table board extends outwards and combines with the fixed table board to form a complete supporting table top, and the length and width dimensions of the dining table are the external dimensions after the fixed table board and the movable table board are combined. This state increases the occupied space of the dining table and improves the usable area of the dining table top. The settings of the sliding mechanism and the lifting mechanism make the dining table easy to operate and the structure safe and reliable.

[0009] In a further solution, the movable table board further has a third state. When the movable table board is in the third state, at least a part of the movable table board extends beyond the fixed table board, and the upper surface of the movable table board is not in the same plane as the upper surface of the fixed table board.

[0010] By adopting the above technical solution, in the third state, the upper surface of the movable table board is higher or lower than the upper surface of the fixed table board, so that there are different levels on the upper surface of the dining table, which can meet different usage requirements of users.

[0011] In a further solution, the lifting mechanism includes a link assembly and a rotating assembly. One end of the link assembly is connected to the movable table board, and the other end is connected to the rotating assembly. The rotating assembly is connected to the sliding mechanism. When the rotating assembly rotates, it can drive the movable table board to move closer to or away from the sliding mechanism through the link assembly.

[0012] By adopting the above technical solution, the rotating assembly drives the link assembly and the movable table board to move up and down through rotational movement, with a simple and reliable structure and convenient operation.

[0013] In a further solution, the link assembly includes a slide rod, a first link, and a second link. One end of the slide rod is fixedly connected to the movable table board, and the other end is hinged to the first link. One end of the second link is hinged to the first link, and the other end is fixedly connected to the rotating assembly. When the rotating assembly drives the movable table board to move through the link assembly, the slide rod slides relative to the sliding mechanism.

[0014] By adopting the above technical solution, when the rotating component rotates, it drives the second connecting rod to rotate. When the second connecting rod rotates, it drives the first connecting rod to rotate. Since the sliding rod is slidably connected to the sliding mechanism, the rotation of the first connecting rod can drive the sliding rod to slide relative to the sliding mechanism. In this way, the sliding rod can drive the movable table board to achieve lifting movement.

[0015] In a further solution, the sliding rod is provided with a limiting platform, and the sliding mechanism is provided with a limiting member. When the movable table board is in the storage state, the limiting platform abuts against the sliding mechanism, and the movable table board cannot move closer to the sliding mechanism; when the movable table board is in the extended state, the first connecting rod or the second connecting rod abuts against the limiting member, and the movable table board cannot move closer to the sliding mechanism.

[0016] By adopting the above technical solution, the limiting platform can achieve the position stability of the movable table board in the storage state, facilitating the movable table board to be accurately placed in the storage space. The limiting member can ensure that when the upper surface of the movable table board bears pressure in the extended state, the movable table board will not move closer to the sliding mechanism, maintaining the support stability of the movable table board. Thus, the movable table board is convenient for storage and can achieve the stability and safety in the extended state.

[0017] In a further solution, the rotating component includes a knob and a rotating shaft fixedly connected to the knob. The knob is rotatably connected to the sliding mechanism, and the rotating shaft is fixedly connected to the second connecting rod.

[0018] By adopting the above technical solution, the knob can rotate relative to the sliding mechanism. By rotating the knob, the rotating shaft is driven to rotate, and then the second connecting rod is driven to rotate, realizing the lifting movement of the movable table board.

[0019] In a further solution, the sliding mechanism and / or the knob is provided with a limiting mechanism for restricting the rotation of the knob relative to the sliding mechanism.

[0020] By adopting the above technical solution, the limiting mechanism can restrict the rotation of the knob relative to the sliding mechanism. In this way, according to the needs of the user, the rotation angle of the knob relative to the sliding mechanism can be restricted, and then the lifting height of the movable table board can be controlled to meet different usage requirements of the user.

[0021] In a further solution, the rotating component includes a knob and a rotating shaft connected to the knob. The rotating shaft is slidably connected to the second connecting rod and / or the knob. The knob is provided with a groove / key, and the sliding mechanism is provided with a key / groove that cooperates with the groove / key. When the key and the groove cooperate, the knob can slide relative to the sliding mechanism. When the key and the groove are disengaged, the knob can rotate relative to the sliding mechanism.

[0022] By adopting the above technical solution, when the slot and the key are matched, the rotation of the knob relative to the sliding mechanism can be limited, thereby achieving a stable position of the movable platform. When the slot and the key are disengaged, the knob can rotate relative to the sliding mechanism to adjust the lifting height of the movable platform. After the height of the movable platform is adjusted, the sliding knob makes the slot and the key match to limit the rotation of the knob relative to the sliding mechanism, thereby fixing the position of the movable platform. This solution can not only achieve flexible adjustment of the height of the movable platform, but also limit the position of the movable platform by the key and the slot, thereby ensuring the stability of the movable platform.

[0023] In a further solution, at least two grooves are provided, so that when the movable platform is in the storage state and the extended state, the key cooperates with the groove to limit the rotation of the knob.

[0024] By adopting the above technical solution, when the movable table is in the storage state, the movement of the movable table can be limited by the cooperation of the key and the slot to maintain a stable storage state; when the movable table is in the extended state, the cooperation of the key and the slot can prevent the movable table from moving downward when it is under pressure, thereby ensuring the functional requirements of the movable table.

[0025] In a further solution, an adjusting member is threadedly connected between the sliding rod and the movable platform, and the distance between the movable platform and the sliding mechanism can be adjusted by rotating the adjusting member.

[0026] By adopting the above technical solution, the height difference between the fixed table top and the movable table top can be adjusted by the adjusting member, and the upper surface of the movable table top can be flush with the upper surface of the fixed table top by fine-tuning the height difference.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. The transformable dining table of the present application can change the occupied space of the dining table, increase the usable area of the dining table surface, and is flexible and convenient to operate.

[0053] The following will describe in detail some implementation manners of the present invention with reference to the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0054] Embodiment 1

[0055] Please refer to Figures 1-14 , which is a schematic structural diagram of an embodiment of a deformable dining table.

[0056] Please refer to Figure 1 and Figure 2, the deformable dining table of this embodiment includes a fixed table board 1 and a fixed frame 2 connected to the fixed table board 1. A support leg 6 is fixedly connected to one side of the fixed frame 2 away from the fixed table board 1. There are four support legs 6, which can stably support the fixed table board 1. A sliding mechanism 5 is slidably connected to the fixed frame 2. A lifting mechanism 4 is connected to the sliding mechanism 5. One end of the lifting mechanism 4 is fixedly connected to the sliding mechanism 5, and the other end is fixedly connected to the movable table board 3. The lifting mechanism 4 can drive the movable table board 3 to move closer to or away from the sliding mechanism 5.

[0057] There is a storage space 11 between the fixed table board 1 and the fixed frame 2. When the lifting mechanism 4 drives the movable table board 3 to move closer to the sliding mechanism 5 and the sliding mechanism 5 moves closer to the fixed frame 2, the movable table board 3 is in a storage state within the storage space 11. When the sliding mechanism 5 moves away from the fixed frame 2 and the lifting mechanism 4 drives the movable table board 3 to move away from the sliding mechanism 5 and extends out of the outer end face of the fixed table board 1, and the upper surface of the movable table board 3 is flush with the upper surface of the fixed table board 1, the movable table board 3 is in an extended state.

[0058] A reset mechanism is connected between the sliding mechanism 5 and the fixed frame 2. The reset mechanism is used to drive the sliding mechanism 5 to move closer to the fixed frame 2. The reset mechanism is a spring.

[0059] Please refer to Figure 2 , the lifting mechanism 4 includes a link assembly 41 and a rotating assembly 42. One end of the link assembly 41 is connected to the movable table board 3, and the other end is connected to the rotating assembly 42. The rotating assembly 42 is rotatably connected to the sliding mechanism 5. When the rotating assembly 42 rotates, it can drive the movable table board 3 to move closer to or away from the sliding mechanism 5 through the link assembly 41.

[0060] Please refer to Figure 3 , a sliding tube 51 is fixedly provided on the sliding mechanism 5. The sliding mechanism 5 is a cylindrical tube, and the sliding tube 51 is a circular tube fixed on the outer circumference of the cylindrical tube. The link assembly 41 is provided with a sliding rod 411 that is slidably connected to the sliding tube 51.

[0061] Please refer to Figure 4 , the link assembly 41 further includes a first link 412, a second link 413, and a connecting piece 414. One end of the sliding rod 411 is fixedly connected to the movable table board 3 through the connecting piece 414, and the other end is hinged to the first link 412. One end of the second link 413 is hinged to the first link 412, and the other end is fixedly connected to the rotating assembly 42. When the rotating assembly 42 drives the movable table board 3 to move through the link assembly 41, the sliding rod 411 slides relative to the sliding mechanism 5.

[0062] The rotating assembly 42 includes a knob 421, a rotating disk 422, a fixing pin 423 and a rotating shaft 424. The knob 421, the rotating shaft 424 and the rotating disk 422 are fixedly connected into one body through the fixing pin 423. The rotating shaft 424 is fixedly connected to the second connecting rod 413. The rotating disk 422 is rotatably connected to the sliding mechanism 5. Two spaced fixing plates 52 are fixedly arranged in the sliding mechanism 5. The fixing plate 52 is provided with a shaft hole 521 and a limiting hole 522. The rotating shaft 424 is rotatably arranged in the shaft hole 521, and a limiting rod 523 passes through the limiting hole 522. By rotating the knob 421, the rotating disk 422 can be driven to rotate, thereby realizing the movement of the connecting rod assembly 41.

[0063] Please refer to Figures 4-6 , when the movable table board 3 is in the storage state, the limiting piece abuts against the sliding mechanism 5, and the movable table board 3 cannot move close to the sliding mechanism 5.

[0064] Please refer to Figure 7 and Figure 8 , the dining table is in the storage state. The using surface of the tabletop of the dining table is the upper surface of the fixed table board 1. The movable table board 3 is stored in the storage space 11 below the fixed table board 1. This state can reduce the occupied space of the dining table.

[0065] Please refer to Figures 9-10 , when the rotating assembly 42 rotates, the connecting rod assembly 41 is driven to move through the rotating shaft 424. The second connecting rod 413 abuts against the limiting rod 523, and the movable table board 3 cannot move close to the sliding mechanism 5. It is also possible to make the first connecting rod 412 abut against the limiting rod 523 as needed to limit the movement of the connecting rod assembly 41. At this time, the movable table board 3 is in the extended state.

[0066] Please refer to Figure 11 and Figure 12 , the dining table is in the extended state. The sliding mechanism 5 moves away from the fixed frame 2. The lifting mechanism 4 drives the movable table board 3 to rise to be flush with the upper surface of the fixed table board 1 and abut against the fixed table board 1. In this way, the fixed table board 1 and the movable table board 3 are connected to form a complete supporting surface.

[0067] Please refer to Figure 13 and Figure 14 , the third state of the dining table. When the movable table board 3 is in the third state, the movable table board 3 at least partially extends outside the fixed table board 1, and the upper surface of the movable table board 3 is higher or lower than the upper surface of the fixed table board 1. In this way, a stepped supporting surface of the dining table can be formed.

[0068] The operation process or principle of this embodiment is as follows: When the dining table is in the storage state, pull the sliding mechanism 5 outwards. The sliding mechanism 5 slides away from the fixed frame 2. When at least part of the movable table board 3 protrudes from the fixed table board 1, this is the third state. At this time, the movable table board 3 can be driven by the lifting mechanism 4 to be higher or lower than the upper surface of the fixed table board 1 to achieve support surfaces at different levels. When the movable table board 3 completely protrudes from the fixed table board 1, rotate the rotating assembly 42. The rotating assembly 42 drives the connecting rod assembly 41 to move, and the connecting rod assembly 41 drives the movable table board 3 to rise, making the upper surfaces of the movable table board 3 and the fixed table board 1 flush. This is the extended state, which can expand the support surface of the dining table. When it is necessary to return from the extended state to the storage state, rotate the rotating assembly 42 to make the movable table board 3 move closer to the sliding mechanism 5, and push the sliding mechanism 5 towards the fixed frame 2 to make the movable table board 3 enter the storage space 11.

[0069] Embodiment Two

[0070] Please refer to Figure 15 , which is different from Embodiment One in that an adjusting member 7 is further connected between the fixed frame 2 and the fixed table board 1. The adjusting member 7 includes an adjusting rod 71 and an adjusting nut 72. The adjusting rod 71 is fixedly connected to the fixed table board 1, the adjusting nut 72 is threadedly connected to the adjusting rod 71, and the adjusting nut 72 abuts against the sliding tube 51. By rotating the adjusting nut 72, the distance between the movable table board 3 and the sliding mechanism 5 can be adjusted through the adjusting rod 71.

[0071] Embodiment Three

[0072] Please refer to Figure 16 , which is different from Embodiment Two in that a limiting block 53 is fixedly connected to one end of the sliding mechanism 5 on the fixed frame 2. When the movable table board 3 is in the extended state, the limiting block 53 abuts against the fixed frame 2 to limit the sliding mechanism 5 from continuing to move away from the fixed frame 2, so as to limit the position of the sliding mechanism 5 and prevent the sliding mechanism 5 from detaching from the fixed frame 2.

[0073] Embodiment Four

[0074] It is different from Embodiment One in that the sliding mechanism 5 or the rotating assembly 42 is provided with a limiting mechanism for restricting the rotation of the rotating assembly 42 relative to the sliding mechanism 5. Specifically, a plurality of through holes are provided on the pipe wall of the sliding mechanism 5, and circular holes corresponding to the pipe wall of the sliding mechanism 5 are provided on the rotating disc 422. After the rotating disc 422 rotates, the rotating disc 422 and the sliding mechanism 5 can be fixedly connected by inserting a pin into the circular hole on the rotating disc 422 and the through hole on the pipe wall of the sliding mechanism 5 to limit the rotation of the rotating disc, thereby restricting the rotation of the rotating shaft 424 and further restricting the movement of the connecting rod assembly 41 driving the movable table board 3.

[0075] Embodiment Five

[0076] The difference from the first embodiment is that the rotating shaft 424 is slidably connected to the second connecting rod 413 or the rotating disk 422. The rotating disk 422 is provided with a groove or a key, and the sliding mechanism 5 is provided with a key or a groove that cooperates with the groove or the key. When the key and the groove cooperate, the rotating disk 422 can slide relative to the sliding mechanism 5. When the key and the groove are disengaged, the rotating disk 422 can rotate relative to the sliding mechanism 5. There are at least two grooves, so that when the movable platen 3 is in the storage state and the extended state, the key and the groove cooperate to limit the rotation of the rotating disk 422, thereby realizing the stability of the position of the movable platen 3. Through the solution of this embodiment, the rotation of the rotating assembly 42 can be realized, and the position limitation of the rotating assembly 42 during the rotation process can also be realized.

[0077] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes, modifications, substitutions and variations, and all of these changes, modifications, substitutions and variations fall within the scope of the present invention claimed.
