Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to deformable furniture structures. Background Technology

[0002] Traditional folding beds and other deformable furniture typically include a bed board or other load-bearing components and folding legs that are hinged to the load-bearing components. The folding legs are equipped with a limiting platform for rotation. When the folding legs are rotated open, the limiting platform abuts against the load-bearing components such as the bed board to keep the folding legs in the open state.

[0003] However, in traditional folding beds and other deformable furniture, the folding legs are close to the axis of hinge between the folding legs and the supporting components (where the lever arm is small) and are subjected to a large torque (due to the lever principle). This makes the limiting platform of the folding legs prone to local deformation and damage. In addition, if the folding legs are accidentally kicked, they are also more likely to rotate, and their stability in the open position is poor. Summary of the Invention

[0004] One object of the present invention is to solve or alleviate the above-mentioned technical problems.

[0005] The present invention employs a deformable furniture structure, which includes at least a supporting member, a folding leg, and a locking member; the supporting member includes a longitudinal portion; the folding leg has one end hinged to the longitudinal portion, allowing the folding leg to rotate in a vertical plane parallel to the longitudinal portion; the locking member includes a hinge portion and a connecting portion, the hinge portion being hinged to the supporting member so that the connecting portion can rotate in a plane perpendicular to the longitudinal portion; the connecting portion is detachably connected to the folding leg.

[0006] The present invention achieves the following effects: it can stably bear the load in the locked state, and the force of the bearing component can be evenly distributed to the folding legs. At the same time, it can rotate the folding legs and the locking component to reduce the space occupied by the whole.

[0007] A further technical solution is provided, wherein the longitudinal portion includes a second longitudinal segment and a first longitudinal segment; the second longitudinal segment is hinged to the first longitudinal segment and is able to rotate relative to the first longitudinal segment in a vertical plane parallel to the first longitudinal segment, and the second longitudinal segment abuts against the first longitudinal segment and can only rotate unidirectionally relative to the first longitudinal segment.

[0008] This technical solution can further reduce the space occupied by the overall deformable furniture structure while ensuring the load-bearing capacity of the longitudinal part.

[0009] A further technical solution is that the hinge portion includes a first locking segment and a second locking segment; the first locking segment abuts against the second locking segment; and the contact surfaces of the first locking segment and the second locking segment are located on the same plane as the contact surfaces of the second longitudinal segment and the first longitudinal segment.

[0010] In this technical solution, the first locking segment and the second locking segment can be folded synchronously with the longitudinal part, which facilitates the folding operation. At the same time, they can also be synchronously offset with the longitudinal part to ensure the overall strength.

[0011] A further technical solution is that the first locking segment is hinged to the second locking segment, and the axis of hinge between the first locking segment and the second locking segment is perpendicular to the axis of hinge between the second longitudinal segment and the first longitudinal segment. When the locking member is folded, the axis of hinge between the first locking segment and the second locking segment is collinear with the axis of hinge between the second longitudinal segment and the first longitudinal segment.

[0012] This technical solution enables the first locking segment and the second locking segment to rotate synchronously, facilitating operation, while ensuring accurate alignment when the first locking segment and the second locking segment abut against each other.

[0013] In a further technical solution, the locking member also includes an anti-bending portion parallel to the hinge portion. The anti-bending portion includes a first anti-bending section and a second anti-bending section hinged to the first anti-bending section. The axis of hinge between the second anti-bending section and the first anti-bending section is perpendicular to the axis of hinge between the second longitudinal section and the first longitudinal section. When the locking member is folded, the axis of hinge between the first anti-bending section and the second anti-bending section is collinear with the axis of hinge between the second longitudinal section and the first longitudinal section.

[0014] This technical solution enables the first locking segment and the second locking segment to rotate synchronously, facilitating operation. It ensures accurate alignment when the first locking segment and the second locking segment abut against each other, while also further improving the overall strength of the locking component and preventing the hinge from bending.

[0015] A further technical solution includes a longitudinal portion as a longitudinal beam and a transverse portion as a transverse beam; a hinged portion is hinged to the transverse portion and abuts against the bottom surface of the transverse portion, and / or, the hinged portion is hinged to the longitudinal portion and abuts against the bottom surface of the longitudinal portion.

[0016] This technical solution enables the force on the load-bearing components to be evenly transmitted to the folding legs or fixed legs.

[0017] A further technical solution also includes a hinged clamp with a limiting groove; the cross-section of the hinged part is circular; the hinged clamp fits into the hinged part and is fixedly connected to the longitudinal part and / or the transverse part; the hinged part is provided with a limiting hole facing the limiting groove, and the limiting member fits into the limiting groove and is fixedly connected to the limiting hole.

[0018] This technical solution can ensure that the connecting part is accurately aligned with the other end of the folding leg or the fixed leg, while also limiting the rotation angle of the connecting part and preventing excessive rotation of the connecting part from causing a decrease in its load-bearing capacity.

[0019] A further technical solution also includes a fixed support leg, with one end of the bearing member hinged to the fixed support leg and the bearing member hinged to the folding support leg; both ends of the locking member are provided with connecting parts, and the connecting parts at both ends of the locking member are detachably connected to the folding support leg respectively.

[0020] This technical solution reduces the overall length of the deformable furniture structure, allowing it to fit into narrower spaces, while the fixed legs serve as a base for the roughly vertical load-bearing components, ensuring their stable placement.

[0021] A further technical solution includes a second longitudinal section and a first longitudinal section hinged to the second longitudinal section. One end of the first longitudinal section is hinged to a fixed support leg, and the second longitudinal section is hinged to a folding support leg. After the first longitudinal section is rotated to a vertical position relative to the fixed support leg, the other end of the second longitudinal section can be rotated to a position flush with the bottom surface of the fixed support leg.

[0022] This technical solution features a deformable furniture structure with a relatively small overall length and height, allowing it to fit into narrow and low spaces. At the same time, the other end of the second longitudinal section and the bottom surface of the fixed legs can contact the ground, ensuring that the folded components are placed stably and securely.

[0023] A further technical solution involves providing a load-bearing support on the fixed leg, which abuts against the load-bearing support when the supporting component rotates to a horizontal position.

[0024] This technical solution can further improve the overall strength of furniture structures that are deformable during use.

[0025] A further technical solution is that the hinge part is parallel to the longitudinal part, and the folding support leg is located between the locking part and the longitudinal part.

[0026] This technical solution allows the locking element to fit snugly against the longitudinal part, while also creating a gap between the hinge and the longitudinal part to distribute the weight of the supporting element and the load on it more evenly, and to ensure the strength of the folding legs when folded.

[0027] A further technical solution involves fixing the support leg with an extension that extends beyond the top surface of the support member.

[0028] Further technical solutions also include detachable connectors; the detachable connectors are screws, buckles, wire ropes or hooks and are respectively connected to the connecting part and the folding leg, or respectively connected to the connecting part and the fixed leg.

Detailed Implementation

[0049] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0050] As a specific embodiment, the deformable furniture structure of the first embodiment includes at least a supporting member 1, a folding leg 2, and a locking member 4.

[0051] in: The load-bearing member 1 includes a longitudinal portion 11. For example, the load-bearing member 1 includes a longitudinal portion 11 that is a longitudinal beam and a transverse portion 12 that is a transverse beam, making the load-bearing member 1 a frame structure. It should be noted that the load-bearing member 1 can also be a plate-like structure. For a plate-like load-bearing member 1, it can be understood that it is formed by filling material inside the load-bearing member 1 of the frame structure. Therefore, the plate-like load-bearing member 1 must also have a longitudinal portion 11 and a transverse portion 12. Thus, the load-bearing member 1 can be simplified as a rectangular plane, and the longitudinal portion 11 can be simplified as the adjacent sides of the rectangular plane or line segments parallel to the sides. The transverse portion 12 can be simplified as the side of the rectangular plane perpendicular to the longitudinal portion 11 or line segments parallel to the sides. Usually, the load-bearing member 1 is provided with a reinforcing beam 119, which is fixedly connected to multiple transverse portions 12 that are transverse beams to improve the strength of the load-bearing member 1. It is easy to understand that when the reinforcing beam 119 is perpendicular to the transverse portion 12 that is a transverse beam, the reinforcing beam 119 can also serve as the longitudinal portion 11.

[0052] The folding leg 2 has one end hinged to the longitudinal section 11, allowing it to rotate in a vertical plane parallel to the longitudinal section 11. For example, the longitudinal section 11 can be a longitudinal beam, with a hinge axis such as a bolt passing through the longitudinal section 11 and one end of the folding leg 2, thus hinged to the longitudinal section 11. The folding leg 2 is rotated so that its other end (the end hinged to the longitudinal section 11) approaches the longitudinal section 11, until the entire folding leg 2 is horizontal and coincides with the longitudinal section 11. It is easy to understand that multiple folding legs 2 located at the same end of the longitudinal section 11 but in different vertical planes can be connected by a linkage beam 29, allowing them to rotate synchronously. It should be noted that, as... Figure 10 As shown, both the folding support leg 2 and the fixed support leg 3 (described later) are placed on a horizontal plane (i.e., Figure 10 On the line 3); based on this, it is easy to understand that the direction perpendicular to the horizontal plane is the vertical direction.

[0053] The locking member 4 includes a hinge portion 41 and a connecting portion 42. The hinge portion 41 is hinged to the bearing member 1 so that the connecting portion 42 can rotate in a plane perpendicular to the longitudinal portion 11.

[0054] The connecting part 42 is detachably connected to the folding leg 2 (i.e., the end away from the hinged joint between the folding leg 2 and the longitudinal part 11). Figure 13As shown, the deformable furniture structure is in a locked state (first state) at this time. In this state, the connecting part 42 cannot rotate in a vertical plane parallel to the longitudinal part 11, so that the connecting part 42, the folding leg 2, and the longitudinal part 11 form a relatively stable triangular support structure, allowing the bearing member 1 to support the cushion, human body, or other objects placed on it. At the same time, the folding leg 2 can raise the height of the bearing member 1. At this time, the force on the bearing member 1 can be transmitted to the folding leg 2 through the locking part 4, so that the force on the bearing member 1 can be evenly distributed to the folding leg 2.

[0055] like Figure 14 As shown, the other end of the folding leg 2 is separated from the connecting part 42. At this time, the folding leg 2 can rotate in a vertical plane parallel to the longitudinal part 11. Rotate the folding leg 2 so that its other end is close to the longitudinal part 11, so that the included angle between the folding leg 2 and the longitudinal part 11 becomes the smallest, for example, the smallest zero degree, so that the folding leg 2 is horizontal and coincides with or parallel to the longitudinal part 11. At this time, the deformable furniture structure is in the folding leg retracted state (second state), and the overall height of the deformable furniture structure decreases due to the rotation of the folding leg 2.

[0056] like Figure 15 As shown, after the other end of the folding leg 2 is separated from the connecting part 42, the connecting part 42 can rotate in a plane perpendicular to the longitudinal part 11. Rotating the locking member 4 brings the connecting part 42 closer to the bearing member 1, for example, closer to the transverse part 12 of the bearing member 1, minimizing the angle between the locking member 4 and the bearing member 1, for example, to zero degrees, making the locking member 4 horizontal and overlapping or parallel to the bearing member 1. At this time, the overall height of the deformable furniture structure decreases due to the rotation of the locking member 4. It should be noted that after the other end of the folding leg 2 is separated from the connecting part 42, the locking member 4 can be rotated first, followed by the folding leg 2. When both the folding leg 2 and the locking member 4 are rotated to their minimum angles with the bearing member 1, the overall height of the deformable furniture structure is minimized. For example, for a structure with a supporting component 1 and four folding legs 2, four locking components 4 can be set to correspond to the four folding legs 2 respectively. When the four folding legs 2 and the locking components 4 are all rotated to the minimum angle with the supporting component 1, the overall height of the deformable furniture structure is reduced to the minimum.

[0057] It should be noted that after rotating the deformable furniture structure as a whole, its height can also be converted into its length or width. Therefore, it can be understood that when the folding legs 2 and locking components 4 are rotated to their minimum angle with the supporting component 1 (i.e., after the folding legs 2 and locking components 4 are folded), the overall height, length, or width of the deformable furniture structure becomes minimal, thus reducing the space occupied by the deformable furniture structure as a whole. It is easy to understand that although the volume of the components of the deformable furniture structure remains unchanged, the change in the relative positions of the components alters the space occupied by the deformable furniture structure as a whole.

[0058] As can be seen from the above, the deformable furniture structure of the first embodiment can stably bear the load in the locked state, so that the force of the bearing member 1 is evenly distributed to the folding leg 2, while also being able to rotate (i.e. fold) the folding leg 2 and the locking member 4 to reduce the space occupied by the whole.

[0059] As one specific implementation, the longitudinal portion 11 includes a second longitudinal segment 112 and a first longitudinal segment 111. The second longitudinal segment 112 is hinged to the first longitudinal segment 111 and can rotate relative to the first longitudinal segment 111 in a vertical plane parallel to the first longitudinal segment 111. The second longitudinal segment 112 abuts against the first longitudinal segment 111 and can only rotate unidirectionally relative to the first longitudinal segment 111. For example, the bottom surface of the second longitudinal segment 112 and the bottom surface of the first longitudinal segment 111 are respectively fixedly connected to the hinge 9, so that the second longitudinal segment 112 and the first longitudinal segment 111 are hinged by the hinge 9, and the end face of the second longitudinal segment 112 abuts against the end face of the first longitudinal segment 111, for example, by a buffer 8 made of a flexible material such as rubber or plastic, so that the second longitudinal segment 112 and the first longitudinal segment 111 are approximately on the same straight line. When the end face of the second longitudinal segment 112 abuts against the end face of the first longitudinal segment 111, the second longitudinal segment 112 can only rotate in the forward direction relative to the first longitudinal segment 111, but cannot rotate in the reverse direction relative to the first longitudinal segment 111. For example, the first longitudinal segment 111 of a longitudinal part 11 is provided with a folding leg 2 and a locking member 4, and the second longitudinal segment 112 of the same longitudinal part 11 is also provided with a folding leg 2 and a locking member 4. After the folding leg 2 and the locking member 4 are folded, the second longitudinal segment 112 rotates unidirectionally relative to the first longitudinal segment 111, causing the first longitudinal segment 111 and the second longitudinal segment 112 of the same longitudinal part 11 to fold in half. Figure 16As shown in the figure, two sets of first longitudinal segments 111 and second longitudinal segments 112 (i.e., two first longitudinal segments 111 and two second longitudinal segments 112, totaling four components) are displayed. Both sets of first longitudinal segments 111 and second longitudinal segments 112 are generally vertical, with space or contact between them. The second longitudinal segment 112 rotates outward relative to the first longitudinal segment 111 (i.e., away from the space or contact surface between the two sets of first longitudinal segments 111 and second longitudinal segments 112) and rotates in one direction only. However, the second longitudinal segment 112 cannot rotate inward relative to the first longitudinal segment 111 (i.e., towards the space or contact surface between the two sets of first longitudinal segments 111 and second longitudinal segments 112). This specific embodiment can be used as a portable coffee table, etc. In this embodiment, after the folding legs 2 and locking members 4 are folded, the second longitudinal segment 112 rotates relative to the first longitudinal segment 111, causing the longitudinal part 11 to fold itself. This can further reduce the space occupied by the deformable furniture structure as a whole. At the same time, when the second longitudinal segment 112 abuts against the first longitudinal segment 111, the second longitudinal segment 112 cannot rotate in the opposite direction relative to the first longitudinal segment 111, and the load-bearing capacity of the longitudinal part 11 can also be ensured.

[0060] As one specific implementation, the hinge portion 41 includes a first locking segment 411 and a second locking segment 412; the first locking segment 411 and the second locking segment 412 abut against each other, for example, through a buffer member 8; and the contact surfaces of the first locking segment 411 and the second locking segment 412 (which inevitably make contact when abutting) are located on the same plane as the contact surfaces of the second longitudinal segment 112 and the first longitudinal segment 111. After the locking member 4 is folded, as the second longitudinal segment 112 of the longitudinal portion 11 rotates relative to the first longitudinal segment 111, the second locking segment 412 can also rotate synchronously with the longitudinal portion 11 relative to the first locking segment 411; when the first longitudinal segment 111 of the longitudinal portion 11 abuts against the second longitudinal segment 112, the first locking segment 411 can also abut against the second locking segment 412 synchronously with the longitudinal portion 11. In this embodiment, the first locking segment 411 and the second locking segment 412 can be folded synchronously with the longitudinal portion 11, which facilitates the folding operation. At the same time, they can also be simultaneously resisted by the longitudinal portion 11 to ensure overall strength.

[0061] In one specific implementation, the first locking segment 411 and the second locking segment 412 are hinged, and the axis of hinge between the first locking segment 411 and the second locking segment 412 is perpendicular to the axis of hinge between the second longitudinal segment 112 and the first longitudinal segment 111. Furthermore, when the locking member 4 is folded, the axis of hinge between the first locking segment 411 and the second locking segment 412 is collinear with the axis of hinge between the second longitudinal segment 112 and the first longitudinal segment 111. Figure 12As shown, the axis of hinge between the second longitudinal segment 112 and the first longitudinal segment 111 is LINE1, and the axis of hinge between the first locking segment 411 and the second locking segment 412 is perpendicular to the paper (see reference). Figure 10 The point on the paper where line 2 (LINE2) is located is a point on line 1 (LINE1). Figure 12 The axis of hinge between the first locking segment 411 and the second locking segment 412 is shown to be perpendicular to the axis of hinge between the second longitudinal segment 112 and the first longitudinal segment 111. In this embodiment, the first locking segment 411 and the second locking segment 412 are always connected, which allows the first locking segment 411 and the second locking segment 412 to rotate synchronously, facilitating operation, while ensuring accurate alignment when the first locking segment 411 and the second locking segment 412 abut against each other.

[0062] As one specific embodiment, the locking member 4 also includes an anti-bending portion 43 parallel to the hinge portion 41. The anti-bending portion 43 and the hinge portion 41 are fixedly connected by a reinforcing portion 439. For example, the reinforcing portion 439 is annular and is welded to the anti-bending portion 43 and the hinge portion 41 respectively. The anti-bending portion 43 includes a first anti-bending section 431 and a second anti-bending section 432 hinged to the first anti-bending section 431. The axis of hinge between the second anti-bending section 432 and the first anti-bending section 431 is perpendicular to the axis of hinge between the second longitudinal section 112 and the first longitudinal section 111. When the locking member 4 is folded, the axis of hinge between the first anti-bending section 431 and the second anti-bending section 432 is collinear with the axis of hinge between the second longitudinal section 112 and the first longitudinal section 111. This embodiment enables the first locking segment 411 and the second locking segment 412 to rotate synchronously, facilitating operation. It ensures accurate alignment when the first locking segment 411 and the second locking segment 412 abut against each other, while also further improving the overall strength of the locking member 4 and preventing the hinge portion 41 from bending. It is easy to understand that even if the first locking segment 411 and the second locking segment 412 are not hinged, this embodiment can still achieve the aforementioned technical effects.

[0063] As one specific implementation, the deformable furniture structure of the first embodiment also includes a detachable connector 421. The detachable connector 421 is a detachable connection structure of the prior art such as a screw, buckle, wire rope, or hook, and is connected to the connecting part 42 and the folding leg 2 respectively, or to the connecting part 42 and the fixed leg 3 respectively, so that the connecting part 42 is detachably connected to the other end of the folding leg 2 or the fixed leg 3. For example, the detachable connector 421 is a screw that passes through the connecting part 42 and screws into the other end of the folding leg 2.

[0064] As one of the specific implementation methods, such as Figure 12As shown, the hinge portion 41 is parallel to the longitudinal portion 11, and the folding leg 2 is disposed between the locking member 4 and the longitudinal portion 11. In this embodiment, the connecting portion 42 of the locking member 4 can rotate inward (i.e., away from the longitudinal portion 11) without being blocked by the folding leg 2, thereby allowing the locking member 4 to fit against the longitudinal portion 11 while also ensuring that there is a gap between the hinge portion 41 and the longitudinal portion 11 so as to bear the weight of the supporting member 1 and the load on it more evenly, and to ensure the strength of the folding leg 2 when folded.

[0065] As one specific embodiment, the bearing member 1 includes a longitudinal portion 11 as a longitudinal beam and a transverse portion 12 as a transverse beam; a hinge portion 41 is hinged to the transverse portion 12 and abuts against the bottom surface of the transverse portion 12, and / or, the hinge portion 41 is hinged to the longitudinal portion 11 and abuts against the bottom surface of the longitudinal portion 11. For example, multiple transverse portions 12 as transverse beams are each hinged to a hinge portion 41, and the bottom surfaces of the multiple transverse portions 12 abut against the hinge portion 41 respectively. When viewed from above, the hinge portion 41 is approximately perpendicular to the multiple transverse portions 12. In this embodiment, the weight of the bearing object such as a cushion or human body is transmitted to the hinge portion 41 through the bottom surface of the transverse portion 12 and / or the bottom surface of the longitudinal portion 11. The hinge portion 41 then transmits the force to the folding leg 2 or the fixed leg 3 through the connecting portion 42. This allows the force on the bearing member 1 to be evenly transmitted to the folding leg 2 or the fixed leg 3, preventing excessive local stress on the deformable furniture structure and thus preventing easy damage.

[0066] As one specific implementation, the deformable furniture structure of the first embodiment further includes a hinge clamp 5 with a limiting groove 51; the cross-section of the hinge portion 41 is circular, making the hinge portion 41 as a whole cylindrical tube; the hinge clamp 5 fits against the hinge portion 41 and is fixedly connected to the longitudinal portion 11 and / or the transverse portion 12, such that the hinge portion 41 is hinged to the transverse portion 12 and abuts against the bottom surface of the transverse portion 12, and / or the hinge portion 41 is hinged to the longitudinal portion 11 and abuts against the bottom surface of the longitudinal portion 11; the hinge portion 41 is provided with a limiting member hole 511 facing the limiting groove 51, and the limiting member 512 such as bolts fits through the limiting groove 51 and is fixedly connected to the limiting member hole 511. The limiting member 512 can prevent the hinge part 41 from moving relative to the bearing member 1 in the longitudinal direction 11, and can ensure that the connecting part 42 is accurately aligned with the other end of the folding leg 2 or the fixed leg 3. At the same time, it can limit the rotation angle of the connecting part 42 and prevent the connecting part 42 from rotating excessively, which would reduce its load-bearing capacity (the connecting part 42 bears the load in a non-vertical state, which causes it to be subjected to a shear force perpendicular to the connecting part 42, resulting in a decrease in its load-bearing capacity).

[0067] As one specific implementation, the deformable furniture structure of the first embodiment also includes a fixed support leg 3. The fixed support leg 3 is typically provided with a weight-reducing groove 39 so that it is U-shaped when viewed from the front. One end of the bearing member 1 is hinged to the fixed support leg 3, and the bearing member 1 is hinged to the folding support leg 2. Both ends of the locking member 4 are provided with connecting parts 42, so that the locking member 4 is U-shaped. The connecting parts 42 at both ends of the locking member 4 are detachably connected to the folding support leg 2. For example, there are two bearing members 1 arranged in a mirror image of the fixed support leg 3, but there can also be one bearing member 1 or other quantities. The fixed support leg 3 is placed on the ground, and after the folding support leg 2 and the locking member 4 are folded, it is as follows: Figure 15 The locking element is in the retracted state (third state). The entire supporting element 1 is rotated upwards, making it approximately vertical. At this point, as shown... Figure 16 As shown, the deformable furniture structure is in the load-bearing component retracted state (fourth state); although the overall height of the deformable furniture structure increases at this time, the overall length of the deformable furniture structure decreases, allowing it to be placed in a narrower space. At the same time, the fixed support leg 3 can serve as the base of the roughly vertical load-bearing component 1, ensuring that the load-bearing component 1 is placed stably.

[0068] As one specific embodiment, the longitudinal portion 11 includes a second longitudinal segment 112 and a first longitudinal segment 111 hinged to the second longitudinal segment 112. One end of the first longitudinal segment 111 is hinged to the fixed support leg 3, and the second longitudinal segment 112 is hinged to the folding support leg 2. When the first longitudinal segment 111 rotates relative to the fixed support leg 3 to a vertical position, the other end of the second longitudinal segment 112 (i.e., the other end of the second longitudinal segment 112 hinged to the folding support leg 2) can rotate to a position flush with the bottom surface of the fixed support leg 3. Figure 16 As shown, the second longitudinal segment 112 is rotated so that it is flush with the bottom surface of the fixed support 3. At this time, both the first longitudinal segment 111 and the second longitudinal segment 112 are approximately vertical, and the second longitudinal segment 112 is placed on the ground with its bottom surface flush with the fixed support 3. Figure 17As shown, the deformable furniture structure is in the retracted state of the second longitudinal beam segment (fifth state). It is easy to understand that the sum of the height of the first longitudinal segment 111 (the distance between the hinge point of the first longitudinal segment 111 and the fixed leg 3 and the hinge point of the first longitudinal segment 111 and the second longitudinal segment 112) and the height of the fixed leg 3 (i.e., the vertical distance from the bottom surface of the fixed leg 3 to the hinge point of the first longitudinal segment 111 and the fixed leg 3) is approximately equal to the height of the second longitudinal segment 112 (i.e., the distance from the hinge point of the first longitudinal segment 111 and the second longitudinal segment 112 to the other end of the second longitudinal segment 112). The deformable furniture structure of this embodiment has a small overall length and height, and can be placed in narrow and low spaces. At the same time, the other end of the second longitudinal segment 112 and the bottom surface of the fixed leg 3 can contact the ground. The first longitudinal segment 111 and the second longitudinal segment 112 are not easy to rotate due to self-equal factors, which can ensure that the folded state of the supporting member 1 is stable (that is, the first longitudinal segment 111 and the second longitudinal segment 112 are roughly parallel) and placed stably.

[0069] As one specific implementation method, the fixed support leg 3 is provided with a load-bearing support part 31, and the bearing member 1 is rotated to a horizontal position (see example). Figure 10 When the horizontal plane where line LINE3 is shown is rotated (so that the entire supporting member 1 is parallel to the horizontal plane), it abuts against the load-bearing support part 31. This embodiment can further improve the overall strength of the deformable furniture structure when the supporting member 1 is in use.

[0070] The deformable furniture structure of the second embodiment differs from that of the first embodiment in the number of supporting members 1 and the fixed support leg 3. In the second embodiment, the deformable furniture structure has one supporting member 1, and the fixed support leg 3 is fixedly provided with an extension 32 extending beyond the top surface of the supporting member 1. In the locked state (first state), the extension 32 of the deformable furniture structure of the second embodiment can serve as the two side support components of the backrest, correspondingly taking the form of a folding chair, folding sofa frame, etc. In other embodiments, the extension 32 can also be a support component detachably connected to the fixed support leg 3. After the folding support leg 2 and the locking member 4 are folded, the supporting member 1 rotates upward until it is approximately parallel to the extension 32. At this time, the overall length of the deformable furniture structure of the second embodiment is smaller, and the overall space occupied is smaller.
