Utility Model Content

[0005] The utility model aims to provide a footrest mechanism for an ergonomic chair to solve the problem that the sole of the foot cannot move significantly after being fitted with the top surface of the footrest, which may reduce the user's health condition due to long-term sitting on the chair and lack of exercise.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a footrest mechanism of an ergonomic chair, comprising a fixing strip, the fixing strip is flipped and arranged on one side of a footrest plate, a lifting frame is arranged above the fixing strip, a fixing plate is arranged on one side of the lifting frame, a plurality of hinges are arranged on the top surface of the lifting frame, the lifting frame and the fixing plate are rotatably arranged through the hinges, a plurality of mounting openings are provided on the top surface of the footrest plate, a roller is rotatably arranged inside the mounting opening, positioning columns are respectively fixed at both ends of the roller, positioning grooves are respectively provided on both sides of the interior of the mounting opening, a bearing is fixed inside the positioning groove, the inner wall surface of the inner ring of the bearing is fixedly inserted with the surface of the positioning column, and a plurality of massage blocks are fixed on the surface of the roller.

[0007] Preferably, two supporting bars are fixed to the top surface of the fixing bar, and two sliding grooves are provided on the inner bottom surface of the lifting frame, and the sliding grooves are slidably inserted into the supporting bars. A connecting plate is slidably arranged inside the lifting frame, and the bottom surface of the connecting plate is fixed to the top surface of the supporting bar. A fixing column is fixed inside the lifting frame, and a spring is surrounded on the surface of the fixing column.

[0012] Compared with the prior art, the footrest mechanism of an ergonomic chair adopting the above technical solution has the following beneficial effects:

[0013] 1. When the user sits on the ergonomic chair, the user's feet will be placed on the horizontal footrest. When the user's soles are in contact with the top surface of the footrest, since multiple rollers are evenly distributed on the top surface of the footrest, and the rollers use bearings inside the mounting opening to reduce the friction resistance during rotation, the user's feet placed on the top surface of the footrest will slide on the top surface of the footrest from time to time, which can play a role in moving the leg muscles to a certain extent. In addition, the user can also take off shoes and socks to make the soles of the feet fully contact with the massage blocks on the surface of the rollers, and the soles of the feet can be massaged during the rolling process, so as to achieve the effect of relaxing the meridians and activating blood circulation on the soles of the feet;

[0014] Second, the user will first pass the fixing bolts in the mounting plate through the rotating holes and connect them to the ergonomic chair. Since the leg lengths of each user are different, the user will first adjust the top surface of the footrest according to his or her own leg length. At this time, the staff will first adjust the height of the footrest. When separating the lifting frame and the fixed plate, the user will press the footrest downward with his or her feet. The downward moving footrest will drive the fixing strip, the support strip and the connecting plate to move downward synchronously, and squeeze the spring on the surface of the fixing column during the downward movement. Then, the lifting frame and the fixed plate will be folded so that the rear side of the lifting frame fits with the front side of the fixed plate, so that the limit strip slides and engages with the limit groove, so that the support strip can be fixed at the current position, and at the same time, the fixing strip and the footrest are fixed at the current height, thereby increasing the applicability of the footrest.

[0015] 3. When the footrest is not needed, the user will push the footrest upwards. Before they are fully fitted, the user will first use the connecting plate to lift the interception bar, and then fully fit the top surface of the footrest with the front side of the lifting frame. Then, the user puts down the lifted interception bar. The interception bar will slide downward under the action of gravity, so that the rear side of the interception bar will fit with the front side of the vertically placed footrest, preventing the vertically placed footrest from separating from the lifting frame. The footrest can be folded up to reduce the space occupied and facilitate on-site storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] During use, when the user sits on the ergonomic chair, the user's feet will be placed on the horizontal footrest 2. When the soles of the user's feet contact the top surface of the footrest 2, since multiple rollers 6 are evenly distributed on the top surface of the footrest 2, and the rollers 6 use bearings 8 inside the mounting opening 5 to reduce the friction resistance during rotation, the user's feet placed on the top surface of the footrest 2 will slide on the top surface of the footrest 2 from time to time, which can play a role in activating the leg muscles to a certain extent. In addition, the user can also take off his shoes and socks to make the soles of the feet fully contact with the massage blocks 10 on the surface of the rollers 6, and the soles of the feet can be massaged during the rolling process, thereby achieving the effect of relaxing the meridians and activating blood circulation in the soles of the feet.

[0024] like Figure 1 and Figure 2 As shown, two supporting bars 11 are fixed to the top surface of the fixing bar 1, and two sliding grooves 18 are provided on the inner bottom surface of the lifting frame 3, and the sliding grooves 18 are slidably inserted with the supporting bars 11, and a connecting plate 12 is slidably provided inside the lifting frame 3, and the bottom surface of the connecting plate 12 is fixed to the top surface of the supporting bar 11, and a fixing column 13 is fixed inside the lifting frame 3, and a spring 14 is surrounded on the surface of the fixing column 13, and the fixing column 13 is slidably inserted with the connecting plate 12, one end of the spring 14 is fixed to the inner bottom surface of the lifting frame 3, and the other end of the spring 14 is fixed to the bottom surface of the connecting plate 12, a limiting bar 17 is fixed to one side of the supporting bar 11, and a plurality of limiting grooves 16 are provided on one side of the fixing plate 4, and the limiting bar 17 is slidably inserted with the limiting groove 16, and mounting plates 25 are respectively fixed on both sides of the fixing plate 4, and a rotating hole 26 is provided on one side of the mounting plate 25, and a fixing bolt 15 is rotatably provided inside the rotating hole 26.

[0027] During use, when the footrest 2 is not needed, the user will push the footrest 2 upwards so that one side of the footrest 2 fits against one side of the lifting frame 3. Before they are completely fitted together, the user will first use the connecting plate 24 to lift the interception bar 23, and then make the top surface of the footrest 2 fit completely against the front side of the lifting frame 3, and then put down the lifted interception bar 23. The interception bar 23 will slide downward under the action of gravity, so that the rear side of the interception bar 23 fits against the front side of the vertically placed footrest 2, preventing the vertically placed footrest 1 from separating from the lifting frame 3, so that the footrest 2 can be folded up, which can reduce the space occupied and facilitate on-site storage.
