Description

Technical Field

[0001] The utility model relates to the technical field of chairs and seats, in particular to a chair that is convenient for assisting standing. Background Art

[0002] At present, most common power-assisted standing chairs use an electric push rod installed under a single sofa chair to push the bottom of the sofa chair, so that the sofa chair flips forward and upward for a certain distance, and the sofa chair cushion then pushes the person's buttocks to rise forward and upward, thereby achieving the function of helping people stand up.

[0003] However, when this type of electric sofa chair is pushed by the electric push rod, the armrests on both sides of the sofa chair will sink quickly, causing the person to lean forward when standing up due to the armrests being too low, and unable to hold the armrests firmly, resulting in unstable center of gravity, leaning forward, and other undesirable phenomena. Secondly, this type of sofa chair needs to be connected to a power source before use, which is affected by the usage scenario, resulting in a limited scope of application; in addition, this type of sofa chair is heavy, not easy to move, and expensive, and has a small scope of use. Utility Model Content

[0004] Based on this, the purpose of the utility model is to overcome the shortcomings of the prior art and provide a chair that is convenient for assisting standing. The seat cushion can be flipped significantly by pressing the armrest slightly, thereby achieving the effect of lifting the human body's buttocks to assist standing, reducing the risk of the user falling forward, and has low cost and is easy to move.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A chair that facilitates standing, comprising a chair frame, a seat cushion plate, and armrests, wherein the seat cushion plate is placed on the top of the chair frame, and rotating parts are respectively extended vertically downward at both ends of the front side of the seat cushion plate, and a seat cushion rotating shaft is arranged on the upper front side of the chair frame, and two rotating parts are rotatably mounted on the seat cushion rotating shaft; the armrests are respectively symmetrically arranged on both sides of the chair frame, each armrest can be rotatably arranged on the chair frame, and the upper end of each armrest is higher than the top of the chair frame, and a first cross bar is arranged at the lower ends of the two armrests; the rotating part and the first cross bar are connected by a connecting rod, and the two ends of the connecting rod are respectively rotatably arranged on the rotating part and the first cross bar.

[0007] As an implementation manner, a chair back is connected to the upper rear side of the chair frame.

[0026] See also Figures 1 to 5; The present embodiment provides a chair that is convenient for assisting standing, comprising a chair frame 10, a seat cushion plate 20, and an armrest member 30, wherein the seat cushion plate 20 is placed on the top of the chair frame 10, and the two ends of the front side of the seat cushion plate 20 respectively extend a rotating portion 21 vertically downward, and a seat cushion rotating shaft 11 is mounted on the upper front side of the chair frame 10, and two rotating portions 21 are rotatably mounted on the seat cushion rotating shaft 11; the armrest members 30 are symmetrically arranged on both sides of the chair frame 10, each armrest member 30 can be rotatably arranged on the chair frame 10, and the upper end of each armrest member 30 is higher than the top of the chair frame 10, and the lower ends of the two armrest members 30 are arranged with a first cross bar 50; the rotating portion 21 and the first cross bar 50 are connected by a connecting rod 60, and the two ends of the connecting rod 60 are respectively rotatably arranged on the rotating portion 21 and the first cross bar 50.

[0027] Furthermore, a chair backrest 40 is connected to the upper rear side of the chair frame 10 of the present invention. In the present invention, the chair frame 10 includes two front legs and two rear legs arranged vertically, a front crossbar is connected between the two front legs, a rear crossbar is connected between the two rear legs, and side crossbars are respectively connected between the upper ends of the two front legs and the upper ends of the two rear legs; a plurality of top crossbars are arranged at intervals between the two side crossbars. Optionally, diagonal rods 41 are respectively arranged between the top sides of the chair frame 10 and the chair backrest 40.

[0028] In the embodiment of the utility model, the armrest member 30 is higher than the upper end of the chair frame 10 and has a V-shaped structure. A handrail rod 31 is mounted on the top of the armrest member 30, and the front end of the handrail rod 31 is tilted toward the front and upward. Further, the chair frame 10 is provided with an armrest shaft 12, and the two ends of the armrest shaft 12 extend out of the two sides of the chair frame 10 respectively, and the two armrest members 30 are rotatably mounted on the two ends of the armrest shaft 12.

[0029] Therefore, the two armrests 30 of the utility model can rotate relative to the chair frame 10, thereby forming the first lever structure of the chair. When the user presses on the front side of the armrest rod 31, the armrest 30 can be driven to rotate and the first cross bar 50 can be flipped backward, thereby driving the connecting rod 60 to move backward and downward.

[0030] Furthermore, a second cross bar 70 is provided between the two rotating parts 21, and the second cross bar 70 is arranged parallel to the seat cushion rotation shaft 11 and the first cross bar 50, and the second cross bar 70 is located below the seat cushion rotation shaft 11; one end of the connecting rod 60 is rotatably mounted on the second cross bar 70, and the other end of the connecting rod 60 is rotatably mounted on the first cross bar 50.

[0031] Therefore, the seat cushion plate 20 of the utility model can rotate relative to the chair frame 10, thereby forming a second lever structure of the chair. When the connecting rod 60 moves rearward and downward, the connecting rod 60 simultaneously drives the second cross bar 70 to move rearward and downward, thereby driving the seat cushion plate 20 to flip forward and upward around the seat cushion rotation axis 11, thereby achieving the effect of helping the user to stand up.

[0032] In order to prevent the seat cushion 20 from turning over too much, in the embodiment of the utility model, a limit block 22 is provided on one side of the rotating part 21, and the limit block 22 is located above the rear side of the front leg frame, and the limit block 22 is located below the side cross bar.

[0033] Compared with the conventional technology, the seat cushion plate 20 of the present invention is placed on the top surface of the chair frame 10, and its front end is rotatably mounted on the seat cushion shaft 11 through two rotating parts 21, and the two armrests 30 are rotatably arranged on both sides of the chair frame 10, and the lower ends of the two armrests 30 are provided with a first cross bar 50, and the first cross bar 50 is connected to the rotating part 21 through a connecting rod 60. Therefore, the present invention rotates the armrest 30 and the seat cushion plate 20 as lever structures respectively, and connects the two lever structures through a connecting rod 60, so that when the user sits on the seat cushion plate 20, the seat cushion plate 20 can be greatly flipped by only slightly pressing the top front end of the armrest 30, thereby providing the user with an effect of assisting standing, and when the human body stands forward, the position of the armrest 30 is still maintained at a higher position to support the human body, so that the center of gravity of the human body will not tilt forward, thereby preventing the user from falling due to unstable center of gravity. In addition, the utility model has a novel design, a simple structure, a low cost, does not require power, is easy to move, and has no restrictions on usage scenarios.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model for facilitating standing assistance. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these belong to the protection scope of the utility model.
