Description

Technical Field

[0001] The utility model relates to the technical field of chair structures, in particular to a chair structure which is easy to transport. Background Art

[0002] A chair is a piece of furniture for daily life. Its main function is to provide a flat surface for people to sit on. It is usually combined with a backrest and armrests (sometimes without armrests) to support the back, arms and buttocks of the human body. Chairs can appear in various occasions, such as homes, offices, restaurants, classrooms, theaters, etc., providing convenience for people's lives and work.

[0003] Some chairs currently in use do not have a folding function. Chairs without a folding function will take up more space when stored, which may become a problem for people with limited living space, especially when multiple chairs need to be stored. The problem of space occupation will be more obvious. In outdoor picnics, camping or travel, where chairs need to be moved or carried, it will cause inconvenience in carrying. In addition, some chairs do not have the function of supporting the user's lower limbs, and cannot enable users to get a better rest effect. When sitting for a long time, the chair does not provide sufficient support for the lower limbs, especially the knees and feet, which will cause the lower limb muscles to be in a tense state for a long time, causing fatigue and discomfort.

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 As shown, a chair structure that is easy to transport includes a seat cushion 1, and a fixing frame 2 is bolted to the bottom of the seat cushion 1. When the seat cushion 1 moves, the fixing frame 2 can be driven to move. Both sides of the top of the fixing frame 2 are of inclined design. Both sides of the bottom of the fixing frame 2 are bolted to a first connecting piece 3. When the fixing frame 2 moves, the first connecting pieces 3 on both sides can be moved. The surfaces of the first connecting pieces 3 on both sides are hinged with supporting legs 4. The inner walls of the supporting legs 4 on both sides are rotatably connected to connecting shafts 5. One side of the surface of the connecting shafts 5 on both sides is rotatably connected to tilting frames 6. When the first connecting pieces 3 on both sides move, the supporting legs 4 on both sides can be driven to rotate. When the supporting legs 4 on both sides are rotated to the appropriate positions, they can cooperate with the tilting frames 6 on both sides to stably place the chair in one place. The inclined surfaces on both sides of the top of the fixing frame 2 are bolted to limit plates 7. The length of the limit plates 7 is greater than the distance between the tilting frames 6 on both sides. The bottom of the supporting legs 4 and the bottom of the tilting frames 6 on both sides are provided with anti-skid pads 13. The material of the anti-skid pads 13 is rubber, and the anti-skid pads 13 can prevent the user from slipping and protecting the floor.

[0023] The lower limb support mechanism 10 includes a second connecting member 101, the top of the second connecting member 101 is bolted to one side of the bottom of the seat cushion 1, the inner wall of the second connecting member 101 is rotatably connected to a fixing rod 102, and one end of the surface of the fixing rod 102 is bolted to a support plate 103. When the user needs a proper rest, rotating the fixing rod 102 can rotate the support plate 103. When the support plate 103 is fully unfolded, the user can place the lower limbs on the support plate 103.

[0024] The positioning mechanism 12 includes a tension spring 121, the number of which is two. One end of the surface of the tension spring 121 on both sides is fixedly connected to the upper and lower sides of the surface of one side of the fixed shell 11 respectively. The other end of the surface of the tension spring 121 on both sides is fixedly connected to a T-shaped plate 122. A baffle 123 is bolted to one side of the surface of the T-shaped plate 122. A fixed plate 124 is bolted to one side of the top of the baffle 123. Both sides of the surface of the fixed plate 124 are slidably connected to the inner walls of the two sides of the fixed shell 11 respectively. Pulling the T-shaped plate 122 can make the tension springs on both sides 121 is stretched, and when the T-plate 122 moves, the baffle 123 is driven to move. When the baffle 123 moves to a suitable position, the blocking of the fixed rod 102 is released. When the baffle 123 moves, the fixed plate 124 is driven to move. Under the action of the fixed plate 124, the baffle 123 can be prevented from easily escaping from the interior of the fixed shell 11. An auxiliary groove 14 is provided on one side of the top of the baffle 123. The size of the auxiliary groove 14 is larger than the size of the second connecting member 101. Under the action of the auxiliary groove 14, the baffle 123 can be prevented from obstructing the second connecting member 101.

[0025] Working principle: When the chair needs to be stored, pull one side of the seat cushion 1. When the seat cushion 1 moves, it can drive the fixing frame 2 to move. Then the fixing frame 2 moves to drive the first connecting members 3 on both sides to move. Next, the first connecting members 3 on both sides move to drive the supporting legs 4 on both sides to rotate. When the supporting legs 4 on both sides are rotated to the appropriate position, they can be staggered and overlapped with the tilting frames 6 on both sides. At the same time, when the fixing frame 2 moves, the limit plate 7 can be moved. When the limit plate 7 moves to the maximum distance, the folding angle of the seat cushion 1 can be limited. Under this action, the floor space of the chair can be reduced. When the user needs a better rest, pull the T-plate 122. When the T-plate 122 moves, the two sides can be The tension spring 121 is stretched, and when the T-plate 122 moves, the baffle 123 can be driven to move, and then the movement of the baffle 123 can drive the fixed plate 124 to move, and then when the baffle 123 moves to the appropriate position, the blocking of the fixed rod 102 can be released, and then the fixed rod 102 can be rotated under the action of its own weight. When the fixed rod 102 rotates, the supporting plate 103 can be moved, and then the user rotates the fixed rod 102 again until it is fully unfolded, so that the supporting plate 103 is in a parallel state, and then the pull on the T-plate 122 is released. Under the action of the tension springs 121 on both sides, the baffle 123 can block the fixed rod 102 again.
