Fig. 1 is a schematic structural view of each component of the chair provided by the present invention. As shown in fig. 1, the chair of the present embodiment mainly includes: a seat board and a seat frame A, a back board and a back support B, a leg board and a leg support C. The seat frame is formed by connecting and enclosing 4 seat frame upright posts A2, 2 seat frame side connecting rods A31, a plurality of transverse connecting rods A32, a supporting connecting rod A33, 2 universal pulleys and 1 position control pulley assembly A5 according to the figure; the seat board a1 is connected with the seat frame through a connecting board a41 arranged at the upper end of the a21 upright post and can be conveniently rotated and lifted by taking the a41 as a supporting point (as shown in fig. 3). The back panel B1 is connected with the seat frame through a connecting plate a41 arranged at the upper end of the a21 upright post, and can be conveniently rotated to be raised or inclined by taking the a41 as a supporting point (as shown in fig. 5 and 6). The back support is formed by connecting 2 vertical rods B21, 2 cross rods, 2 directional pulleys and 1 position control pull rod B3 as shown in the figure. The back support is connected with the middle of the back of the backboard B1 at a proper position of the top cross bar B22, and can conveniently rotate by taking the connecting position as a supporting point. Particularly, the center point of the lower cross bar B22 of the back bracket is connected with the position control pull rod B3, and the position control pull rod B3 can conveniently rotate by taking the connection point as a supporting point. The leg plate C11 and the leg plate C12, the leg plate C11 and the bracket C21, and the leg plate C12 and the bracket C22 are connected with each other by hinges to form a complete leg plate and a complete leg bracket. And after all the brackets under the leg plates can be folded inwards, the two leg bearing plates can be further folded towards the bracket surfaces.

Further, the leg plate C11 is connected with the seat frame through a connecting strut C3 and a connecting plate a42 arranged at the upper end of the seat frame upright post a 22; the back plate B1 is connected with the seat frame through a connecting plate A41 arranged at the upper end of the A21 upright post, the back support is connected with the seat frame through a connecting support rod B3 and a position control sliding groove A5, and the seat plate and the seat frame A, the back plate and the back support B, the leg plate and the bearing support C form the convertible chair (as shown in figure 2).

In particular, after each bracket under the carrier plate is folded inwards, and the two leg-bearing plates are folded towards the bracket surface, the bracket can conveniently rotate by taking the joint of the connecting strut C3 and the connecting plate A42 as a supporting point, and is completely accommodated in the seat frame (as shown in figure 3). Otherwise, the leg plate and the leg supporter are pulled out from the seat frame and unfolded (see fig. 4, 5 and 6).

In particular, the position control pull rod B3 is embedded in a position control sliding groove a5 in the seat frame to form a position control assembly (as shown in fig. 5 and 6), and the pull rod B3 can slide or be fixed in a limited way in the sliding groove a5 to realize the position control function. When a user needs to adjust the inclination degree of the back plate B1 and the position control assembly is adjusted to be in a non-position control state, the position control pull rod B3 can slide backwards in the position control sliding groove A5, further, the back support can move backwards, and the back plate B1 can be pushed backwards, so that the back plate B1 is gradually inclined from a nearly vertical state to a nearly horizontal state; when the position control component is adjusted to be in a position control state, the position control pull rod B3 cannot slide backwards in the position control slide groove A5, the position is fixed, further, the back support cannot move backwards, the back plate B1 cannot move backwards, and the back plate B1 cannot be fixed and pushed backwards; no matter the position control assembly is in a position control state or an uncontrolled state, the position control pull rod B3 can slide forwards in the position control sliding groove A5, further, the back support and the back plate can move forwards, and the back plate B1 can be pulled forwards to be gradually erected from a nearly horizontal state to a nearly vertical state. (as shown in fig. 2, 5, 6).

In particular, as shown in fig. 1, a universal pulley is additionally arranged at the ground end of the seat frame upright post A21 to provide a ground sliding function and facilitate the carrying of the transformable chair. The landing end of the seat frame upright post A22 is not provided with a pulley, so that the deformation chair can be well stored, and the deformation chair in use is prevented from sliding and shifting on the ground.

It should be understood that the present invention is not limited to the embodiment of the present invention, and the position control assembly is configured to be a sliding type, and in some embodiments, the position control assembly can be configured to be a telescopic rod, a switching type telescopic piece, a rotary type, or even a foldable type position control member.

The utility model discloses the use material is not limited to the wood, also can use all kinds of artifical panel, metal material, plastic material or other. Each seat board (including the leg bearing board) and the seat board frame (bracket) can adopt various forms, such as a board surface, a fence, a frame and the like; the shape of the glass can be various, such as square, flower-shaped or hollow, etc.

The height of the chair seat of the utility model is about 40cm generally; the length and width of the seat plate are preferably 50-60 cm; the width of the back plate is similar to that of the seat plate, and the height of the back plate is generally 65-75 cm; the length and the width of the leg plate are slightly smaller than those of the seat plate, so that the leg plate can be completely accommodated in the seat frame; the leg support is lower than the seat frame and is highest near the seat frame.

For increasing the utility model discloses a practicality can be with position control subassembly, leg board supporting rack set up downwards as far as possible, and the first half of seat frame inner space can be established to the containing box, supplies the utility model discloses when rolling over the receipts and using for the seat, place article such as cotton-wadded quilt.

In order to increase the external aesthetic measure and the comfortable experience of sitting and lying of the user of the utility model, soft cushion materials such as foam are generally required to be spread on each chair plate to be padded, the size of the chair plate is matched with the size of each chair plate, and the chair plate is externally provided with cloth and leather fabric.

The present invention has been described in detail with reference to the embodiments, but the embodiments are only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. The equivalent changes and improvements made within the scope of the present invention should be included in the patent coverage of the present invention.
