DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The arc arrow marked with R in FIG1 indicates the direction in which the leg support frame can rotate.

As shown in Figures 1 to 5, a nap chair includes: a base 2, a seat cushion 3, a backrest 4 and a gas spring 5 with a switch 51, the seat cushion 3 is fixed on the base 2; the backrest 4 includes a supporting portion 41 for the back to lean against, a rotating shaft 42 and a driving portion 43, the supporting portion 41 and the driving portion 43 are respectively fixed on the rotating shaft 42, and the rotating shaft 42 is rotatably connected to the base 2; the cylinder of the gas spring 5 is hinged on the base 2, and the rod of the gas spring 5 is hingedly connected to the end of the driving portion 43 away from the backrest 4; wherein the backrest 4 can be switched between a sitting state or a lying state.

In the present application, the lunch break chair can be switched between a sitting state or a lying state, as shown in FIG1 for the lying state, and as shown in FIG2 for the sitting state. When in use, the user can manually pull the switch 51 of the gas spring 5, and by pushing against it with his own force, the backrest 4 can be tilted to the lying state, and then the switch 51 is turned off, and the backrest 4 will remain in this position. When it is necessary to switch to the sitting state, just pull the switch 51 again, and the gas spring 5 will automatically reset the backrest 4 and convert it to the sitting state. The present application is convenient for users to rest, and in the lying state, the seat cushion 3 and the backrest 4 can form a maximum angle of 170°.

Specifically, it also includes: a guide rail 21, a bracket 7 and a leg support frame 8 arranged along the first direction A1, the guide rail 21 is arranged on the base 2; the bracket 7 is slidably installed on the guide rail 21 and can slide along the first direction; the leg support frame 8 is installed on the bracket 7.

In the present application, when leg support is needed, the user can manually pull the bracket 7 out from under the seat cushion 3 along the first direction A1 to support the thigh, calf or foot position, making it more comfortable when lying down. In the sitting state, the foot support can be retracted along the first direction A1 and hidden. In the present application, the guide rail 21 and the base 2 are an integrated structure, and the guide rail 21 is a pipe structure with a channel. The bracket 7 is inserted into the pipe structure and can move relative to the pipe structure.

Specifically, the leg support frame 8 has a connecting ear 81 and a supporting surface 82. The connecting ear 81 is rotatably connected to the bracket 7 and can be flipped toward or away from the seat cushion 3. A limiting rod 71 is fixed on the bracket 7. On both sides of the connecting ear 81, the leg support frame 8 has a first limiting portion 83 and a second limiting portion 84. When the first limiting portion 83 abuts against the limiting rod 71, the supporting surface 82 faces upward, and when the second limiting portion 84 abuts against the limiting rod 71, the supporting surface 82 faces downward.

In the present application, the leg support frame 8 has a flipping function. After the user pulls the support frame 7 out from under the seat cushion 3, the user can manually flip the support surface 82 upward, and use the first limit portion 83 to abut against the limit rod 71, and by rotating the connection position and the support of the limit rod 71, it cannot be further flipped. In this way, the thigh, calf or foot position can be supported. Moreover, when the leg support frame 8 is flipped outward, the distance relative to the seat cushion 3 can be further extended, which makes it easier to adapt to users with different leg lengths, making it more applicable.

When the leg support frame 8 is not needed, it only needs to be retracted toward the sitting direction. When the leg support frame 8 needs to be hidden, it is flipped toward the seat cushion 3 until the second limit portion 84 abuts against the limit rod 71. In this way, the bracket 7 can be pushed back to the bottom of the seat cushion 3 and hidden, and the leg support frame 8 cannot be seen from above.

Specifically, a headrest 9 is slidably connected to a side of the backrest 4 away from the seat cushion 3 .

The headrest 9 can provide additional neck and head support, so that the user can get a more comfortable experience in a lying or sitting position. The headrest 9 can be adjusted in height and angle to meet the needs of different users and improve the user's comfort and experience.

Specifically, armrests 10 are installed on both sides of the base 2 .

The armrest 10 can provide additional arm and elbow support for the user, making the user feel more comfortable when sitting for a long time.

Specifically, a storage box 11 is fixed on the base 2 .

The storage box 11 provides a convenient storage space, in which the user can place commonly used items, such as files, notebooks, stationery, etc., so that these items are always at hand, improving work efficiency. The storage box 11 can help users organize their desktops in an orderly manner, avoid a messy office environment, and improve work or study efficiency.
