[0031] The utility model will be explained in further detail in combination with the drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic manner, so they only show the structure related to the utility model.

[0032] The utility model embodiment will be explained in further detail in combination with the drawings as follows:

[0033] Referring to Figures 1 to 4 As people's living standards continue to improve, the comfort requirements of the seat are also getting higher and higher, and the functions of the seat are also more and more diverse. In order to improve the comfort of the seat, a leisure chair is derived. Most of the existing leisure chairs have a leg rest function. When the user is sitting, the leg rest can lift the user's calf and have a certain supporting effect on the calf, improving the user's comfort experience. However, the leg rest of most of the existing leisure chairs needs to be manually adjusted when lifting and extending, and the overall concealment is not good, which affects the normal use effect, thereby not conducive to further improving the user experience. In order to solve the above problems, a leisure chair with a hidden leg rest is proposed, which comprises a chair body cushion 1, a support frame 2, a leg rest pad plate 3, a telescopic rod 5 and a first connecting rod 8. The lower surface of the chair body cushion 1 is provided with the support frame 2. The lower end of the support frame 2 is hingedly connected to one end of the first connecting rod 8. The other end of the first connecting rod 8 is hingedly connected to the leg rest pad plate 3. The fixed end of the telescopic rod 5 is hingedly connected to the lower surface of the chair body cushion 1. The telescopic end of the telescopic rod 5 is hingedly connected to the lower surface of the leg rest pad plate 3.

[0034] It also comprises a second connecting rod 9. One end of the second connecting rod 9 is hingedly connected to the lower end of the support frame 2. The other end of the second connecting rod 9 is hingedly connected to the leg rest pad plate 3. The second connecting rod 9 is located on the front side of the first connecting rod 8.

[0035] The leg support extension plate 4 is slidingly connected to the lower surface of the leg support base plate 3, and one end of the third connecting rod 10 is hinged to the lower end of the support frame 2, and the other end of the third connecting rod 10 is hinged to the lower surface of the leg support extension plate 4.

[0036] The leg support base plate 3 is provided with a recess 13, the fixing bolt 11 is inserted into the recess 13 after passing through the leg support extension plate 4, and the fixing nut 12 is threadedly connected with the fixing bolt 11.

[0037] It should be noted that, in the above structure, the transmission mode of the first connecting rod 8 cooperating with the second connecting rod 9 significantly improves the stability of the leg support base plate 3 in retraction and expansion.

[0038] In addition, in the embodiment, the leg support extension plate 4 and the third connecting rod 10 are further included, the leg support extension plate 4 is slidingly connected to the lower surface of the leg support base plate 3, and one end of the third connecting rod 10 is hinged to the lower end of the support frame 2, and the other end of the third connecting rod 10 is hinged to the lower surface of the leg support extension plate 4.

[0039] Further, the third connecting rod 10 and the second connecting rod 9 are in a coincident state.

[0040] It should be further noted that, by setting the leg support extension plate 4 and the third connecting rod 10, the leg support extension plate 4 is moved in extension and contraction relative to the leg support base plate 3 under the driving of the third connecting rod 10.

[0041] Further, the fixing bolt 11 and the fixing nut 12 are further included, the leg support base plate 3 is provided with a recess 13, the fixing bolt 11 is inserted into the recess 13 after passing through the leg support extension plate 4, and the fixing nut 12 is threadedly connected with the fixing bolt 11, the fixing bolt 11 plays a limiting and guiding role, and by setting the fixing bolt 11 and the fixing nut 12, the leg support extension plate 4 moves in extension and contraction along the length direction of the recess 13 under the guiding action of the fixing bolt 11 and the fixing nut 12.

[0042] It needs to be noted that the leg support extension plate 4 is slidably abutted against the lower surface of the leg support pad plate 3, and a small gap is arranged between the leg support extension plate 4 and the leg support pad plate 3. By slidingly abutting the leg support extension plate 4 against the lower surface of the leg support pad plate 3, the friction generated between the two can be avoided, and the deflection caused by the relative movement of the two can also be avoided.

[0043] It is worth mentioning that the recess 13 extends along the length direction of the leg support pad plate 3, and the recess 13 is provided as two, and the two recesses 13 are arranged in parallel with each other. By arranging the recess 13, the positioning and guiding effect of the leg support extension plate 4 is achieved.

[0044] Further, the first fixing frame 6 and the second fixing frame 7 are further included, the first fixing frame 6 is installed on the lower surface of the chair body cushion 1, the second fixing frame 7 is installed on the lower surface of the leg support pad plate 3, the fixed end of the telescopic rod 5 is hinged in the first fixing frame 6, the telescopic end of the telescopic rod 5 is hinged in the second fixing frame 7, the first fixing frame 6 and the second fixing frame 7 are completely the same in structure, and the first fixing frame 6 and the second fixing frame 7 are both U-shaped bent plate structures. By arranging the first fixing frame 6 and the second fixing frame 7, the better installation position of the fixed end and the telescopic end of the telescopic rod 5 is achieved, and the interference phenomenon generated during the use of the telescopic rod 5 is avoided.

[0045] In addition, a notch is arranged at the rear edge of the leg support extension plate 4, the second fixing frame 7 is located in the notch when the leg support extension plate 4 coincides with the leg support pad plate 3, and the shape of the notch is U-shaped. By arranging the notch on the leg support extension plate 4, the avoidance space is provided for the installation of the second fixing frame 7.

[0046] It is particularly emphasized that the support frame 2 is two groups, the telescopic rod 5 is arranged at the center symmetry plane of the lower surface of the chair body cushion 1, and the two groups of support frames 2 are symmetrically arranged about the telescopic rod 5. By arranging the two groups of support frames 2, the stability of the extension of the leg support pad plate 3 is ensured.

[0047] Moreover, the hidden type is mainly reflected in that the leg support does not interfere with the free stretching of the legs of the user after being retracted, so that the purpose of the hidden type is achieved.

[0048] It needs to be emphasized that the embodiments of the utility model are illustrative rather than limiting, so the utility model is not limited to the embodiments described in the specific embodiments, and any other embodiments derived from the technical scheme of the utility model by those skilled in the art also belong to the protection scope of the utility model.
