Description

Technical Field

[0001] This application relates to the field of seating, and more specifically, to a height-adjustable footrest structure. Background Technology

[0002] Traditional desks are designed for adult use and are quite tall, often requiring children to use adult chairs or adjust their chairs to a higher position, making it difficult for their feet to reach the ground. To make them more convenient for children, some study chairs have footrests on the chair legs; however, most existing study chairs do not have adjustable footrests, making them unsuitable for children of different ages and heights. As children grow older and taller, the footrests become largely useless.

[0003] Utility model patent CN201620460166.6 provides "a chair leg with an adjustable height footrest and a study chair using the chair leg". The chair leg includes a main body and multiple supporting legs. The supporting legs radiate outwards around the main body. Each pair of connected supporting legs has a footrest for the user to rest their feet. Each footrest includes a pedal, a connecting rod, at least one pad, and a handwheel. The pedal is located above the supporting leg and connected to the connecting rod. The pad passes through the connecting rod. The connecting rod passes through the supporting leg from top to bottom. The handwheel is located below the supporting leg and connected to the connecting rod. A study chair using a chair leg with an adjustable height footrest allows for easy and convenient adjustment of the footrest height, accommodating children of different ages and heights in a traditional, non-height-adjustable desk environment, thus protecting children's health. However, while the chair can adjust the footrest height, the adjustment process is cumbersome. It requires disassembling the footrests on the two supporting legs, adding or removing pads, and then locking the footrests. The operation is undoubtedly cumbersome and inconvenient, lacking a strong sense of technology. Utility Model Content

[0036] Reference Figure 1-3 The height-adjustable foot pedal structure includes a foot pedal 1, a support rod 2, a lifting rod 3, a base 4, and a control device 5. There are two lifting rods 3, two support rods 2, and two bases 4. The support rod 2 is hollow. One end of the lifting rod 3 is fixed to the foot pedal 1, and the other end is inserted into and slidably connected to the support rod 2. One end of the support rod 2 is inserted into the base 4. The control device 5 is located between the two support rods 2. The height of the foot pedal 1 can be easily adjusted via the control device 5.

[0037] The support rod 2 has a first through hole 6, and the lifting rod 3 has several slots 7. The control device 5 includes a housing 8, a bracket 9, a drive component 10, pins 11, and a return spring 12. The housing 8 includes an upper cover 13 and a lower cover 14. The upper cover 13 is fixed to the support rod 2, and the lower cover 14 is snapped onto the upper cover 13. The bracket 9 is fixed to the lower cover 14. The drive component 10 is movably mounted on the bracket 9. There are two pins 11, which are slidably mounted on the bracket 9, and one end of each pin 11 is inserted into a slot 7 through the first through hole 6. Under the action of the drive component 10, the foot pedal can be freely raised and lowered, and a locking function can be achieved. This saves costs while being simple to operate and convenient to use. The height can be adjusted to a suitable position according to the needs of different users.

[0038] Each of the two pins 11 has a protruding ring 15. The driving component 10 includes a button 16, a fixing plate 17, a connecting plate 18, and a baffle 19. There are two fixing plates 17, connecting plates 18, and baffles 19. The upper end of the cover has a button hole. The button 16 extends through the button hole to the outside of the cover 13. The fixing plate 17 is fixed on both ends of the button 16 and is horizontally arranged. The connecting plate 18 is fixed on one end of the fixing plate 17 and is inclined downward. The connecting plate 18 has a U-shaped plate structure. The pin 11 passes through the groove of the connecting plate 18. The baffle 19 is fixed on one end of the connecting plate 18 and is vertically arranged. The two connecting plates 18 are inclined relative to each other, and one end of the protruding ring 15 abuts against the connecting plate 18. A limiting plate 20 is fixed on the lower cover 14. When the button 16 is pressed down, one end of the baffle 19 abuts against the limiting plate 20. The limiting plate 20 has a second through hole 21, and one end of the pin 11 is inserted into the second through hole 21 and is movably connected to the limiting plate 20.

[0039] A limiting post 22 is fixedly provided on the upper end of the bracket 9. One end of the limiting post 22 is inserted into the button 16 to limit the button 16.

[0040] The lower cover 14 is provided with a reinforcing plate 23, one end of which is connected to the limiting plate 20.

[0041] A decorative panel 24 is installed on the pedal 1 to enhance its aesthetics. The decorative panel 24 can be made of materials such as soft cloth or soft board, thus ensuring comfort while improving aesthetics.

[0042] The specific operation process is as follows:

[0043] When the foot pedal needs adjustment, the user presses button 16, causing it to move downwards. This moves the connecting plate 18 downwards, at which point the protruding ring 15 on the pin 11 abuts against the connecting plate 18. As the connecting plate 18 moves downwards, the protruding ring 15 moves towards one end of the bracket 9 under the action of the inclined surface of the connecting plate 18, bringing the two pins 11 closer together. This compresses the return spring 12, causing one end of the pin 11 to disengage from the slot 7. Pulling up the foot pedal allows the lifting rod 3 to move freely up and down for adjustment, thus achieving the foot pedal's height adjustment. When the user stops pressing button 16, the return spring 12 resets the pedal, causing the protruding ring 15 to slide along the inclined surface of the connecting plate 18, moving the two pins 11 away from each other. This allows the pins 11 to re-insert into the slot 7, securing the foot pedal.

[0044] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
