According to different use scenarios, the users impose different requirements on performance for the seating furniture. For example, the seating furniture for outdoor leisure activities need to be portable, while the seating furniture for office activities is required to be comfort. In some application scenarios, such as wet and slippery environments like bathrooms, the users may wish to select more robust seating furniture with safety as a prioritized requirement.

The inventors of the present disclosure have found that the conventional seating furniture generally suffer from poor stability, resulting in that most seating furniture has a short service life, are easily damaged, and have low reliability in use. Especially when the users of the seating furniture are heavy, or when the users need to sit on the seating furniture for some activities, the seating furniture with insufficient stability are easily deformed. In this case, the seating furniture need to be replaced, which causes great inconvenience and affects use experience. In addition, these seating furniture may even break suddenly when subjected to high impact forces, resulting in injuries to the users upon falling from the seating furniture, with some safety hazards.

To solve the above technical problem, the inventors of the present disclosure devise a seating furniture. The seating furniture is provided with U-shaped support frames. Bottoms of the U-shaped support frames are abutted against a seating furniture plate of the seating furniture to form a first cross-over portion, and opening ends of the U-shaped support frames are connected via connection portions, and a second cross-over portion is formed between the connection portions. In addition, a support rod is arranged between the first cross-over portion and the second cross-over portion, and the support rod is configured to support the seating furniture plate. By the above design, when the seating furniture is under stress, in addition to the support from the U-shaped support frames, the seating furniture is further supported by the support rod arranged between the first cross-over portion and the second cross-over portion. Specifically, the support rod transfers the stress to the second cross-over portion and disperses the stress on the connection portions, such that a middle portion of the seating furniture plate is supported. In this way, the stress suffered by the U-shaped support frames is greatly reduced, such that the seating furniture is uniformly stressed, thereby achieving a stable support effect, effectively improving stability and reliability of the seating furniture, and accommodating safety requirements imposed by users on the seating furniture.

In the meantime, according to the embodiments of the present disclosure, a plurality of telescopic rods are arranged to be respectively movably connected to the opening ends of the U-shaped support frames, such that a height of the seating furniture is flexibly adjusted according to actual needs of the users. In this way, the seating furniture is applicable to different use needs of different users in different scenarios, and an application range of the seating furniture is greatly extended.

The seating furniture according to the embodiments of the present disclosure is applicable to all application scenarios of seating furniture, in particular in scenarios where a stricter safety requirement is imposed for seating furniture, such as bathrooms, and in particular for heavyweight users.

According to some embodiments of the present disclosure, referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic view of a seating furniture, and FIG. 2 is a schematic exploded view of the seating furniture 100 in FIG. 1. As illustrated in FIG. 2, the seating furniture 100 includes a seating furniture plate 10, wherein U-shaped support frames 20 are secured on a side of the seating furniture plate 10. The U-shaped support frames 20 include a first U-shaped support frame 21 and a second U-shaped support frame 22. A bottom of the first U-shaped support frame 21 and a bottom of the second U-shaped support frame 22 are abutted against each other at a middle portion of the seating furniture plate 10 and arranged at an angle to form a first cross-over portion 23. A first connection portion 24 is arranged between opening ends of the first U-shaped support frame 21, and a second connection portion 25 is arranged between opening ends of the second U-shaped support frame 22. The first connection portion 24 and the second connection portion 25 are abutted against each other and arranged at an angle to form a second cross-over portion 26. A support rod 30 is secured between the first cross-over portion 23 and the second cross-over portion 26. The support rod 30 is configured to support the seating furniture plate 10. A plurality of telescopic rods 40 are movably arranged on the opening ends of the first U-shaped support frame 21 and the opening ends of the second U-shaped support frame 22 respectively. The telescopic rods 40 are configured to adjust a height of the seating furniture plate 10.

The seating furniture plate 10 is a structure that is in contact with human bodies during use of the seating furniture 100. Therefore, the seating furniture plate 10 may be designed to different shapes, curved surfaces, or the like, such that the seating furniture plate 10 is adaptive to different body shapes of users, and hence mitigates fatigue due to long-term seating. Optionally, a detachable seating furniture cushion 11 may be further arranged on the seating furniture plate 10. The seating furniture cushion 11 may be made of different materials depending on different use scenarios, such that the seating furniture cushion 11 achieves such an effect as slip resistance, waterproofness, and thermal isolation, or the like, or has a softer texture. In this way, comfort of the seating furniture plate 10 is improved.

The U-shaped support frames 20 are mounted on a side of the seating furniture plate 10, and is configured to support the seating furniture plate 10 and be connected to other support members. The term “a side” refers to bottom side of the seating furniture plate 10 facing downwards with respect to a Z-axis direction illustrated in FIG. 1 or FIG. 2. The U-shaped support frames 20 include the first U-shaped support frame 21 and the second U-shaped support frame 22. The first U-shaped support frame 21 and the second U-shaped support frame 22 have a similar shape, like a letter “U.” With respect to the Z-axis direction in FIG. 1 or FIG. 2, an upper end is the bottom, and a lower end is the opening end. It should be noted that for a common seating furniture, by arranging the first U-shaped support frame 21 and the second U-shaped support frame 22 to provide four-point support for the seating furniture plate, requirements on stability of the seating furniture is accommodated. However, for a seating furniture applicable to some particular scenarios, the number of U-shaped support frames may be increased. For example, a third U-shaped support frame having a similar structure may be additionally arranged, such that six-point support is provided for the seating furniture plate. Arrangement of more U-shaped support frames increases the weight sustainable by the seating furniture, and further improves stability. Therefore, in the embodiments of the present disclosure, the number of U-shaped support frames is not limited.

The bottom of the first U-shaped support frame 21 and the bottom of the second U-shaped support frame 22 are abutted against each other at the middle portion of the seating furniture plate 10 and arranged at an angle to form the first cross-over portion 23. The bottom of the U-shaped support frame 21 and the bottom of the second U-shaped support frame 22 define a larger contact area on a bottom side of the seating furniture plate 10, such that a more stable support effect is achieved. When more U-shaped support frames are additionally arranged on the seating furniture, the bottoms of the plurality of U-shaped support frames are crossed over at a position on a side of the seating furniture plate 10, and this position functions as the first cross-over portion 23.

The first connection portion 24 is arranged between the opening ends of the first U-shaped support frame 21, and the second connection portion 25 is arranged between the opening ends of the second U-shaped support frame 22. The first connection portion 24 and the second connection portion 25 are abutted against each other and arranged at an angle to form the second cross-over portion 26. The first connection portion 24 and the second connection portion 25 are capable of reinforcing the opening ends of the U-shaped support frames 20, mitigating the problem of bending and deformation of the opening ends due to stress, and enhancing stability of the seating furniture. In addition, the first connection portion 24 and the second connection portion 25 also allow users to have their feet rested thereon, which thus improves comfort during use of the seating furniture. When more U-shaped support frames are additionally arranged on the seating furniture, the connection portion may be arranged between the opening ends of each of the U-shaped support frames, and a plurality of connection portions are made to cross over at a position to form the second cross-over portion 26; or alternatively, the connection portions may be selectively arranged between the opening ends of some of the U-shaped support frames to form the second cross-over portion 26. That is, the number of connection portions may be defined according to requirements on support strength and stability of the seating furniture.

The phrase “abutted against each other and arranged at an angle” may be interpreted with reference to FIG. 3 as follows: The first U-shaped support frame 21 and the second U-shaped support frame 22, or the first connection portion 24 and the second connection portion 25 are overlaid with respect to the Z-axis direction as illustrated in FIG. 1 or FIG. 2, and an “X”-like cross-over shape is defined at the overlay position, that is, the first cross-over portion 23 and the second cross-over portion 26.

For a larger contact area between the first cross-over portion 23 and the second cross-over portion 26, deformation may be made at the position where the first U-shaped support frame 21 and the second U-shaped support frame 22 are abutted against each other, or at the position where the first connection portion 24 and the second connection portion 25. For example, the first U-shaped support frame 21 is raised at the position of the first cross-over portion 23 with respect to the Z-axis direction as illustrated in FIG. 1 or FIG. 2, and the second U-shaped support frame 22 is recessed at the position with respect to the Z-axis direction as illustrated in FIG. 1 or FIG. 2, such that corresponding contact surfaces are formed therebetween, and thus better abutment is achieved therebetween. This design is favorable to positioning during assembly, and further improves stability of the connection.

For an improved support strength for the seating furniture, the support rod 30 is secured between the first cross-over portion 23 and the second cross-over portion 26. That is, two ends of the support rod 30 are respectively connected and secured to the first cross-over portion 23 and the second cross-over portion 26. The support rod 30 being configured to support the seating furniture plate 10 may be interpreted as supplying support at a middle position of the bottom of the seating furniture plate 10.

In a conventional seating furniture, the middle position of the seating furniture plate 10 is generally the most frequently contacted part of the seating furniture plate when the user is seated, and is the position suffering the greatest stress. However, in the conventional seating furniture, a support structure generally only supports corner or edge positions of the seating furniture plate 10. Consequently, the middle position of the seating furniture plate 10 has a lowest strength. In the embodiments of the present disclosure, the support rod 30 provides support for the middle position of the seating furniture plate 10, such that the seating furniture plate 10 is capable of sustaining an even greater stress, and thus stability and reliability of the seating furniture 100 are effectively improved. In this way, the seating furniture 100 has a longer service life, and is more suitable for users who are heavy.

For comfort of the seating furniture and accommodation of needs of different users, in the embodiments of the present disclosure, a plurality of telescopic rods 40 are respectively movably arranged at the opening ends of the first U-shaped support frame 21 and the opening ends of the second U-shaped support frame 22. The telescopic rods 40 are configured to adjust the height of the seating furniture plate 10. Specifically, the telescopic rods 40 may be sleeved onto the opening ends of the first U-shaped support frame 21 and the opening ends of the second U-shaped support frame 22. During adjustment, the telescopic rods 40 may telescope upwards and downwards with respect to the Z-axis direction as illustrated in FIG. 1 and FIG. 2. In the meantime, at positions where to stop the telescopic rods 40, securing structures are additionally arranged for stopping and securing the telescopic rods 40, such that the telescopic rods 40 function as support legs to support the seating furniture 100, and the height of the seating furniture plate 10 is maintained at a most comfort state. In this way, different heights or use preferences of users are accommodated, and use comfort of the seating furniture is improved.

The first U-shaped support frame 21, the second U-shaped support frame 22, the first connection portion 24, the second connection portion 25, the support rod 30, and the telescopic rods 40 collaboratively form a support frame of the seating furniture 100. Preferably, the above members or parts may be made of a same rigid material, for example, a metal material or a rigid plastic material or the like, such that these members or parts have a uniform strength, and a procedure of selecting materials is simplified. Further, the above members or parts may be made of an aluminum alloy. The aluminum alloy is light while ensuring the strength, and has a characteristic of anti-rust such that the seating furniture is applicable to a relatively humid environment such as bathrooms or the like.

In the above embodiments, by arranging the U-shaped support frames 20 and arranging the support rod 30 between the first cross-over portion 23 and the second cross-over portion 26, the seating furniture is more securely supported, such that the seating furniture is uniformly stressed, and stability and reliability of the seating furniture is effectively improved. In addition, by arranging the telescopic rods 40 on the opening ends of the U-shaped support frames 20, the height of the seating furniture is adjustable, and hence requirements of different users are accommodated, and comfort of the seating furniture is improved.

For ease of mounting and dismounting of the support rod, in some embodiments, optionally, referring to FIG. 2 and FIG. 3, an insert hole 31 is arranged in one end, facing towards the first cross-over portion 23, of the support rod 30; and a raised portion 12 is extended from the seating furniture plate 10 facing towards the first cross-over portion 23. The raised portion 12 runs through the first cross-over portion 23 and is inserted to the insert hole 31. The support rod 30 is detachably connected to the second cross-over portion 26.

As illustrated in FIG. 2, the insert hole 31 is an opening structure opened in one end of the support rod 30, and has a positioning and retaining effect. A depth of the insert hole 31 needs to accommodate the need of insertion of the seating furniture plate 10. In addition, the depth of the insert hole 31 is not limited. The insert hole 31 may be a blind hole structure not running through the support rod 30, or a through hole running through the support rod 30. As illustrated in FIG. 3, the raised portion 12 is arranged on a bottom side of the seating furniture plate 10, and may be integrally formed with the seating furniture plate 10 or may be another part connected to the bottom side of the seating furniture plate 10. In order that the support rod 30 supports the middle position which is weak in the seating furniture plate 10, preferably, the raised portion 12 may be correspondingly arranged at the middle position of the seating furniture plate 10. A diameter of the raised portion 12 matches a pore diameter of the insert hole 31, such that the raised portion 12 is insertable into the insert hole 31. It should be noted that the diameter of the raised portion 12 shall not be too smaller, otherwise, the raised portion 12 fails to be retained by the insert hole 31, such that the support rod 30 is loose in the insert hole 31, and thus the support effect and reliability of the support rod 30 are affected.

During mounting of the support rod 30, one end of the support rod 30 is connected to the raised portion 12 of the seating furniture plate 10 via the insert hole 31, such that the support rod 30 is in contact with the seating furniture plate 10 and provides support therefor, and wobbling of the support rod 30 is restricted by the raised portion 12. The other end of the support rod 30 is detachably connected to the second cross-over portion 26, with the detachable connection not limited. As an example, as illustrated in FIG. 2, the detachable connection may be practiced using a rotary handle 32 with threads. In this case, the end portion of the support rod 30 shall be provided with a threaded hole. During mounting, the rotary handle 32 runs through the second cross-over portion 26, and mates with and connected to the threaded hole at the end portion of the support rod 30. The above mounting operation is advantageous in that the connection may be practiced manually, with no assistance of other tools.

The above embodiments provide a preferred implementation of securing the support rod. By this implementation, the support rod 30 may be mounted only by secure connection at one end thereof. This implementation reduces difficulty in mounting the support rod 30, and facilitates dismounting and replacement of the support rod 30. It should be understood that the above implementation also have other alternative schemes. For example, as an alternative, an insert hole may be arranged in the seating furniture plate 10, and a raised portion may be arranged at the end portion of the support rod 30. In this alternative implementation, the support rod 30 may still be connected to the seating furniture plate 10 by insertion.

For simplification of assembly of the seating furniture, in some embodiments, optionally, the support rod 30, the first U-shaped support frame 21, and the first connection portion 24 are integrally formed; or the support rod 30, the second U-shaped support frame 22, and the second connection portion 25 are integrally formed.

In the above embodiments, the integral arrangement may also be practiced by welding or the like.

When the support rod 30 and the first U-shaped support frame 21 or the second U-shaped support frame 22 are integrally formed, the first U-shaped support frame 21 and the second U-shaped support frame 22 only need to be spliced and secured to each other. Instead, no other connection operation is needed for the support 30. In this way, the number of parts of the seating furniture is reduced, and the procedure of assembling the seating furniture is simplified.

In the meantime, in addition to integral arrangement of the support rod 30 and the U-shaped support frame, the connection portions may also be integrally formed with the support rod 30 and the U-shaped support frame. For example, the first U-shaped support frame 21 and the first connection portion 24 are integrally formed; and in the meantime, the second U-shaped support frame 22, the second connection portion 25, and the support rod 30 are integrally formed. During use, an integral body of the first U-shaped support frame 21 and an integral body of the second U-shaped support frame 22 are nested to each other for assembly, and then the assembly of the first U-shaped support frame 21 and the second U-shaped support frame 22 is secured to the seating furniture plate 10 to implement mounting of the seating furniture, such that the assembly the seating furniture is more convenient.

In some embodiments, optionally, referring to FIG. 3, a recess 13 is further arranged in a side of the seating furniture plate 10, wherein the recess 13 is configured to receive the bottom of the first U-shaped support frame 21 and the bottom of the second U-shaped support frame 22.

In the above embodiments, by arranging the recess 13, positioning and mounting of the U-shaped support frames 20 are facilitated, a contact area between the U-shaped support frames 20 and the seating furniture plate 10 is increased, and hence stability of the seating furniture 100 is improved.

In some embodiments, optionally, still referring to FIG. 2, a snap-fit portion 41 is arranged at one end of each of the telescopic rods 40, and a plurality of snap-fit holes 27 are spacedly arranged in the opening ends of the first U-shaped support frame 21 and the opening ends of the second U-shaped support frame 22 respectively; wherein the telescopic rods 40 are snap-fitted to the snap-fit holes 27 via the snap-fit portions 41.

Optionally, the snap-fit portions 41 are elastic members each with a boss. The bosses, under stress applied thereon, are capable of retracting within the telescopic rods 40. Without any stress thereon, the bosses are rebounded and protrude outside the telescopic rods 40. When the telescopic rods 40 are inserted into the U-shaped support frames 20, the snap-fit portions 41 and the snap-fit holes 27 are arranged corresponding to each other and cooperate with each other to secure the telescopic rods 40 in the U-shaped support frames 20. In addition, the snap-fit portions 41 may also be other snaps or the like; alternatively, female threads and male threads may also be arranged at the end portions of the connected telescopic rods 40 and the U-shaped support frames 20, and the height of the seating furniture is adjusted by the threads, which is not limited in the embodiments of the present disclosure.

In the embodiments of the present disclosure, where the height of the seating furniture needs to be adjusted, the adjustment is completed only by pressing the snap-fit portions 41, and meanwhile the lengths of the telescopic rods 40 in the U-shaped support frames 20 are adjusted such that the telescopic rods 40 are adjusted to positions corresponding to the snap-fit holes 27.

The above embodiments provide a preferred implementation for arranging the telescopic rods 40. That is, multi-stage connection of the telescopic rods 40 is implemented by the snap-fit portions 41 and the plurality of snap-fit holes 27 that are spacedly arranged. This design has a low difficulty in implementation, and the snap-fit holes 27 only needs to be arranged and the snap-fit portions 41 need to be accordingly arranged. In addition, in this design, during use, the adjustment operation of the telescopic rods 40 is more convenient.

For improvement of flexibility in adjusting the seating furniture, in some embodiments, optionally, still referring to FIG. 2, two ends of the first connection portion 24 and two ends of the second connection portions 25 are respectively connected to the snap-fit holes 27, such that a relative distance between the first connection portion 24 and the second connection portion 25 and the seating furniture plate is adjustable. The length of the support rod 30 is adjustably defined to follow the first connection portion 24 and the second connection portion 25 to adjust the relative distance to the seating furniture plate 10.

Specifically, snap-fit structures similar to the snap-fit portions 41 may be additionally arranged at the two ends of the first connection portion 24 and the two ends of the second connection portion 25, and the first connection portion 24 and the second connection portion 25 are secured to the snap-fit holes 27 via the snap-fit structures. Where adjustment is desired, the snap-fit structure may be detached, and snap-fitted into other snap-fit holes, such that the first connection portion 24 and the second connection portion 25 are adjusted.

The length of the support rod 30 is adjustably defined, with the adjustment not limited. As an example, the support rod 30 may be defined as a combined rod formed by sleeving or snap-fitting a plurality of sections of hollow rods. Where adjustment is desired, the support rod 30 is capable of synchronously telescoping with movements of the first connection portion 24 and the second connection portion 25, and the support rod 30 is fixed upon completion of adjustment, such that during the entire adjustment, the support rod 30 remains connected to the first connection portion 24 and the second connection portion 25. Unlimitedly, the length of the support rod 30 may be adjusted using a fashion of adjustment between the telescopic rods 40 and the U-shaped support frames 20; or with female threads and male threads arranged at the end portions of the plurality of sections of support rods, a height of the support rod 30 may be adjusted by thread connection; or the length may be adjusted in other fashions.

In the above embodiments, on the basis that the telescopic rods 40 are adjustable, an adjustment range of the seating furniture is further extended. That is, the first connection portion 24 and the second connection portion 25 may utilize the original snap-fit holes 27 for adjustment, such that flexibility in adjusting the seating furniture is improved.

For further improvement of stability of the seating furniture, in some embodiments, optionally, referring to FIG. 4, a reinforcement rod 50 is further secured on a side, away from the support rod 30, of the second cross-over portion 26. A length of the reinforcement rod 50 is adjustably defined and matches with a length of the telescopic rod 40. The reinforcement rod 50 is configured to cooperatively support the seating furniture plate 10 with the telescopic rods 40.

The reinforcement rod 50 and the support rod 30 may be integrally formed, or detachably connected to form an integral body. The integral body of the reinforcement rod 50 and the support rod 30 may be arranged to run through the second cross-over portion 26, and directly abutted against the ground to support the middle portion of the seating furniture plate 10. Besides, the reinforcement rod 50 may also be arranged separately from the support rod 30, and secured to the second cross-over portion 26.

Specifically, as an example, when the reinforcement rod 50 is arranged separately from the support rod 30, the reinforcement rod 50 may also be arranged to a combined rod formed by sleeving or snap-fitting a plurality of hollow rods. When the telescopic rods 40 are adjusted, the reinforcement rod 50 is capable of synchronously telescoping, such that the length of the reinforcement rod 50 constantly matches the lengths of the telescopic rods 40. Besides, the reinforcement rod 50 may also be practiced by length adjustable arrangement of the support rod 30 in the above embodiments.

It should be noted that the phrase “lengths of the telescopic rods 40” refers to effective lengths of the telescopic rods 40 during use, and specifically refers to lengths of portions of the telescopic rods 40 extending out of the U-shaped support frames 20. With respect to the phrase “matching the lengths”, as an example, when the seating furniture 100 is properly placed on the ground, the reinforcement rod 50 and the telescopic rods 40 are simultaneously in contact with the ground, such that the reinforcement rod 50 and the telescopic rods 40 simultaneously achieve a support effect. Understandably, the reinforcement rod 50 is an additional support leg arranged at the second cross-over portion 26.

In the above embodiments, by arranging the reinforcement rod 50 and the telescopic rods 40 to cooperatively support the seating furniture plate 10, stability of the seating furniture is further improved.

For further improvement of user experience, in some embodiments, optionally, still referring to FIG. 3, a notch 14 is arranged at a position, corresponding to a tailbone part of a human body, of the seating furniture plate 10.

The inventors of the present disclosure have found that in the conventional seating furniture, the users may feel sore and discomfort at their waists and backs after a long period of sitting. Besides improper sitting postures, the seating furniture plate of the conventional seating furniture causes some compression for tailbones of the users. In the embodiments of the present disclosure, with the notch 14 designed in the seating furniture plate 10, when the users are seated on the seating furniture plate 10, the seating furniture plate 10 offers support on two lateral sides of the users, and the tailbone parts of the users are rightly at the position of the notch 14. In this way, the compression caused by the seating furniture plate 10 to the tailbone parts is avoided, discomfort upon long-term sitting is relieved, and user experience is further improved.

In some embodiments, optionally, referring to FIG. 5, an insert portion 28 is further arranged on a side, close to the seating furniture plate 10, of each of the first U-shaped support frame 21 and the second U-shaped support frame 22. The insert portion 28 is configured to allow an armrest 60 to be inserted therein.
