Description

Technical Field

[0001] The present technical solution relates to the technical field of reclining chairs, and particularly refers to a foldable reclining chair. Background Art

[0002] A reclining chair is a piece of furniture designed for rest and relaxation, usually having an inclined or adjustable backrest, an ergonomic seat, and soft armrests. Based on ergonomics and comfort, it is designed to conform to the body curve of a person. By its adjustment ability, it can achieve semi-reclining, semi-sitting, or fully flat lying positions for users to obtain a comfortable experience, and it is a modern household item.

[0003] The existing reclining chair structure is designed according to the body curve. In order to fully support the human body, the volume of the unfolded reclining chair is larger and the reclining area is increased. However, the handling and storage are restricted by its volume design, resulting in an increase in the difficulty and space requirements for handling and storing the reclining chair. It is difficult for users to easily move and store the reclining chair in the non-use state, making it troublesome to use. Summary of the Invention

[0004] In order to improve the problem that the reclining chair is troublesome to use due to the inability to be conveniently carried and stored, the present technical solution provides a foldable reclining chair.

[0005] The purpose of the present technical solution is achieved as follows:

[0006] A foldable reclining chair includes a main chair frame body. The main chair frame body includes a main frame and a support frame. The upper layer of the main frame is covered with a chair cloth. The main frame includes a seat frame body and a backrest frame body. The relative ends of the seat frame body and the backrest frame body are hinged by a connecting frame.

[0007] The support frame includes a first support and a second support. One end of the first support is hinged to the seat frame body, and the other end extends obliquely downward at the rear. The second support is hinged between the first support and the backrest frame body respectively for supporting the backrest frame body.

[0008] Through the above technical solution, when the foldable reclining chair is in normal use, the main chair frame body is fully unfolded, and the chair cloth is used for reclining. The first support in the support frame is hinged between the seat frame body and the second support, and the second support is hinged between the first support and the backrest frame body, forming a stable triangular support structure. The first support props up the seat frame body, and the second support props up the backrest frame body, stably supporting the sitting part and enhancing the stability of the reclining chair. When the user no longer uses it, by folding the seat frame body and the backrest frame body in the direction away from the reclining side, each component folds according to the hinged points. Those close to the main frame are hinged by the connecting frame. The overall volume of the folded main chair frame body is smaller, making it more convenient for handling and storage, improving the space utilization rate, and thus enhancing the convenience of use.

[0009] Preferably, the seat frame and the back frame each include two arc-shaped branch tubes and a transverse reinforcement tube, and the transverse reinforcement tube is hinged between the arc-shaped branch tubes on opposite sides and is located under the chair cloth.

[0010] Through the above technical solution, the seat frame and the back frame are composed of two arc-shaped branch tubes and a transverse reinforcement tube to form a basic frame structure. The transverse reinforcement tube is arranged under the chair cloth. When a person lies down, the chair cloth is flexible and can support the weight of the human body and reduce the deformation of the chair cloth when under force, thereby extending the life of the chair cloth and improving its durability. By rotating the transverse reinforcement tube to adjust, different support strengths for the chair cloth can be obtained, which is suitable for different human support needs and improves applicability.

[0011] Preferably, the connecting frame is provided with an installation groove, the groove width of the installation groove is adapted to the diameter of the arc-shaped branch pipe, and is used for axial embedding of the arc-shaped branch pipes of the seat frame body and the back frame body.

[0012] Through the above technical solution, the arcuate branch tube ends of the seat frame and the arcuate branch tube ends of the back frame can be axially embedded from the through-holes on both sides of the installation groove and hinged in the installation groove, thereby reducing the shaking or loosening that may occur in the recliner during use and improving the user's sitting and lying experience.

[0013] Preferably, the opposite side walls of the mounting groove form side connecting parts, the connecting frame includes a bottom plate part and two side connecting parts arranged on both sides of the bottom plate part, and the connecting frame has a supporting surface, which is set as the bottom of the mounting groove and is used to limit the rotation of the seat frame body and the back frame body.

[0014] Through the above technical solution, the side connecting part and the bottom plate part are integrally connected to form a complete connecting frame structure. The connecting frame is designed with a supporting surface, which is specifically set to the bottom of the corresponding installation groove. When the seat frame and the back frame are assembled through the connecting frame, when the user lies down, the joint between the seat frame and the back frame is pressed down. The supporting surface effectively limits the relative rotation between the seat frame and the back frame, ensures the stability of the assembly structure, and improves the overall connection strength and safety of use.

[0015] Preferably, hole one is provided at both ends of the side connection part, and hole two is provided on the seat frame body and the back frame body, which can correspond one-to-one with the position of hole one, and hole one is connected to hole two through a hinge to achieve hinged connection.

[0016] Through the above technical solution, the positions of hole one at both ends of the side connection part correspond one to one with the positions of hole two of the seat frame and the back frame. The connecting parts can pass through hole one and hole two to firmly connect the seat frame and the back frame together, while realizing the hinge function between the two.

[0017] Preferably, the first bracket is hinged to the second bracket via a connecting structure;

[0018] Among them, the connecting structure includes a U-shaped piece arranged on bracket one and two connecting pieces arranged on the U-shaped piece. The two connecting pieces are fixed on opposite sides of the U-shaped piece. The connecting piece has a connecting portion extending toward bracket two. Bracket two is provided with hole three. The connecting portion is provided with hole four for the hinge to pass through and connect to hole three.

[0019] Through the above technical solution, bracket one is hinged to bracket two through a connecting structure. The connecting structure includes a U-shaped piece and two connecting pieces fixed on both sides thereof. The connecting piece extends a connecting portion toward bracket two. Hole three of bracket two is aligned with hole four of the connecting portion. After the hinge passes through hole four, the two sections are in hole three, ensuring a stable hinge and improving the flexibility of the overall structure.

[0020] Preferably, the arc-shaped branch pipe has an arrangement groove, and the chair cloth is engaged in the corresponding arrangement groove.

[0021] Through the above technical solution, the chair cloth is fixed by being engaged in the arrangement grooves on the side support rods on both sides, and the embedded part of the chair cloth is squeezed and positioned, which increases the overall aesthetics of the recliner and improves the fixing stability of the chair cloth.

[0022] Preferably, the chair cloth has a convex arc surface and a concave arc surface, and the convex arc surface and the concave arc surface are adjacent to each other.

[0023] Through the above technical solution, the surface of the chair cloth forms a convex arc surface that fits the curve of the human back, and at the same time a concave arc surface is set to adapt to the natural shape of the buttocks and thighs. The convex arc surface and the concave arc surface use a smooth arc transition at the adjacent parts to ensure that the user can feel seamless and comfortable support when lying down, enhance the fit and comfort of the chair cloth, effectively disperse the body pressure, and improve the user experience of lying down for a long time.

[0024] Preferably, a space is left at the position of the chair cloth corresponding to the connecting frame.

[0025] Through the above technical solution, during the cutting and sewing process of the chair cloth, sufficient space will be left according to the shape and position of the connecting frame to ensure that when the recliner is folded, the connecting frame can move smoothly without being hindered by the chair cloth. The integrity of the chair cloth during the folding process avoids damage caused by friction or extrusion, thereby improving the overall durability of the chair cloth.

[0026] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0027] 1. This technical solution forms a stable triangular support structure by hingedly connecting bracket 1 between the seat frame and bracket 2, and bracket 2 between bracket 1 and the back frame. Bracket 1 supports the seat frame, and bracket 2 supports the back frame. Each component folds together according to the hinge points. After folding, the overall volume of the chair frame is smaller, making it easier to carry and store, thereby improving the convenience of use.

[0028] 2. This technical solution is axially embedded through the through-holes on both sides of the installation groove of the arc-shaped branch tube end of the seat frame body and the arc-shaped branch tube end of the back frame body, hinged in the installation groove, pressing down the joint between the seat frame body and the back frame body, and the embedded end rests on the abutment surface, effectively limiting the relative rotation between the two, ensuring the stability of the assembly structure, and improving the overall connection strength and safety of use.

DETAILED DESCRIPTION

[0035] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1 and Figure 2, A foldable deck chair, comprising a chair frame body, which includes a main frame 1 and a support frame 2. The main frame 1 includes a seat frame body 11 and a backrest frame body 12. One end of the seat frame body 11 extends obliquely downward towards the placement plane, and the other end is received at the lower end of the backrest frame body 12. The other end of the backrest frame body 12 extends obliquely upward away from the seat frame body 11. The main frame 1 is provided with a chair cloth 3, which covers the contour of the main frame 1. The upper end surface of the chair cloth 3 has a convex arc surface 18 protruding therefrom and a concave arc surface 19 recessed therein. The arc surfaces are transitioned at the adjacent position of the convex arc surface 18 and the concave arc surface 19. The convex arc surface 18 corresponds to the upper end surface of the chair cloth 3 provided on the seat frame body 11, and the concave arc surface 19 corresponds to the upper end surface of the chair cloth 3 provided on the backrest frame body 12.

[0038] The support frame 2 is located at the rear side below the main frame 1, and it includes a support bracket one 21 and a support bracket two 22. In this embodiment, the support bracket one 21 shown includes a middle connecting rod and curved rods fixed on opposite sides of the connecting rod. One ends of the curved rods on both sides of the support bracket one 21 are located on opposite sides of the seat frame body 11 and are respectively hinged to the seat frame body 11, and the other ends extend obliquely downward to below the support bracket two 22; there are two support brackets two 22, and the support bracket two 22 is a bent rod with a certain arc. One ends of the two support brackets two 22 away from the support bracket one 21 extend upward to opposite sides of the backrest frame body 12 and are hinged to the backrest frame body 12, and its hinge axis is parallel to the hinge axis between the seat frame body 11 and the support bracket one 21. The support bracket one 21 is hinged to the support bracket two 22.

[0039] See Figure 4 , The specific way of hinging the support bracket one 21 and the support bracket two 22 can adopt a connecting structure 13. There are two connecting structures 13, and the two connecting structures 13 correspond to the two support brackets two 22 one by one. Each connecting structure 13 includes a U-shaped piece 131 and two connecting pieces 132. The U-shaped piece 131 is located below the curved rod of the corresponding support bracket one 21. The hole positions on both sides of the U-shaped piece 131 are aligned with the hole positions of the support bracket two 22. The two connecting pieces 132 are located on opposite sides of the U-shaped piece 131. The hole position of each connecting piece 132 is aligned with the hole position on one side of the U-shaped piece 131. Each U-shaped piece 131 has a connecting portion 14, which extends upward to opposite sides of the corresponding support bracket two 22. The connecting portion 14 has a hole four 16, and the support bracket two 22 is provided with a hole three 15. When the position of the hole four 16 is aligned with the hole three 15, the hinge member 23 is passed through the hole four 16 and connected to the hole three 15 to achieve hinging, with the hinge member 23 as the hinge axis.

[0040] See Figure 2 and Figure 3, both the seat frame body 11 and the backrest frame body 12 include two arc-shaped branch pipes 5 and several transverse reinforcing pipes 6. In this example, the situation where both the seat frame body 11 and the backrest frame body 12 include two transverse reinforcing pipes 6 is shown. Each transverse reinforcing pipe 6 is hinged between the arc-shaped branch pipes 5 on the opposite sides and is located below the chair cloth 3. The two arc-shaped branch pipes 5 of the seat frame body 11 are aligned with the two arc-shaped branch pipes 5 of the backrest frame body 12 one by one.

[0041] The seat frame body 11 and the backrest frame body 12 are hinged through the connecting frame 4. There are two connecting frames  4, and the two connecting frames 4 correspond to the arc-shaped branch pipes 5 on both sides one by one. Each connecting frame 4 includes a bottom plate part 41 and side mounting parts 42 arranged on both sides of the bottom plate part 41. An installation groove 7 is formed between the side mounting parts 42 on both sides. The groove width of the installation groove 7 is adapted to the pipe diameter of the arc-shaped branch pipe 5. The arc-shaped branch pipes 5 of the seat frame body 11 and the backrest frame body 12 are respectively axially embedded at both ends of the through part of the installation groove 7. A hole two 10 is opened at the embedded end of the arc-shaped branch pipe 5, and holes one 9 are opened at both ends of the side mounting part 42. When the position of the hole two 10 is aligned with the position of the hole one 9, the hinge part 23 passes through the hole one 9 and is connected to the hole two 10, so that the seat frame body 11 is hinged to one side of the connecting frame 4, and the backrest frame body 12 is hinged to the other side of the connecting frame 4, and the hinge axes are parallel. The connecting frame 4 has a contact surface 8, and the contact surface 8 is set as the bottom of the installation groove 7. When the seat frame body 11 and the backrest frame body 12 rotate around the hinge part 23 towards the direction of the bottom plate part 41, they can be abutted against the contact surface 8 for limiting, as Figure 5 shown, when the seat frame body 11 and the backrest frame body 12 rotate around the hinge part 23 in the direction away from the bottom plate part 41, the seat frame body 11 and the backrest frame body 12 approach each other, and the support one 21 and the support two 22 cooperate to rotate and approach around the hinge point, so as to fold.

[0042] The specific working process of this solution is as follows:

[0043] In this technical solution, the chair cloth 3 is used for lying and reclining. The support one 21 in the support frame 2 is hinged between the seat frame body 11 and the support two 22, and the support two 22 is hinged between the support one 21 and the backrest frame body 12 to form a stable triangular support structure. The support one 21 props up the seat frame body 11, and the support two 22 props up the backrest frame body 12 to stably support the sitting part and enhance the stability of the reclining chair. When the user no longer uses it, by folding the seat frame body 11 and the backrest frame body 12 in the direction away from the lying and reclining side, each component folds according to the hinge points. The ones close to the main frame 1 are hinged through the connecting frame 4. The overall volume of the folded chair frame body is smaller, which is more convenient for handling and storage, improves the space utilization rate, and further improves the convenience of use.
