Abstract
Description
Technical Field
[0001] This utility model relates to the field of seating technology, specifically to a foot pedal height adjustment mechanism and a seat. Background Technology
[0002] Traditional chairs, especially those with a high seating position, often leave the user's legs dangling, leading to leg fatigue. To address this, some existing chairs, particularly child seats, often feature height-adjustable footrests. These footrests typically have multiple height adjustment positions, locked in place by elastic latches. Adjusting the footrest requires the user to exert force over the elastic stress of the spring within the latch, making the adjustment process quite strenuous. Furthermore, when the footrest bears the downward pressure of the user's legs, the latch can easily disengage from its locking slot, causing the footrest to shift abnormally and fail to provide stable leg support. Additionally, the locking mechanism, with its multiple height-adjustable slots, limits the precision of footrest adjustment due to the spacing between adjacent slots, making it difficult to accurately adjust the footrest to a position suitable for the user's body shape and posture. Utility Model Content
[0003] The purpose of this utility model is to provide a foot pedal height adjustment mechanism and a seat, which can achieve precise adjustment of the foot pedal height and provide stable support for the user's legs.

[0017] The seat includes the aforementioned foot pedal height adjustment mechanism.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] In this invention, when the screw and the mounting bracket remain relatively fixed, the external thread of the screw and the internal thread of the threaded sleeve engage with each other to provide stable support for the foot pedal, preventing the foot pedal from shifting abnormally when subjected to downward pressure from the user's legs, thus providing stable support for the user's legs. In addition, the vertical movement of the foot pedal is not restricted, allowing for precise adjustment of the foot pedal height as needed to better adapt to different user body shapes and sitting postures. Furthermore, during adjustment, the screw's rotation freedom is unlocked, allowing for adaptive rotation. The external force required to move the foot pedal up and down is small, making the vertical adjustment of the foot pedal time-saving and labor-saving. Attached Figure Description

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.
[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0031] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a foot pedal height adjustment mechanism for adjusting the height of the foot pedal 20. The foot pedal height adjustment mechanism includes a mounting frame 10, a movable seat 30, a screw 40, and a locking assembly. The mounting frame 10 is located at the bottom of the seat and can be mounted on the seat base or support leg, or it can be part of the seat base or support leg. A vertically extending guide groove 11 is provided on the mounting frame 10. The movable seat 30 has a columnar structure and passes through the guide groove 11, allowing the movable seat 30 to move vertically relative to the mounting frame 10 while preventing rotation of the movable seat 30 relative to the mounting frame 10. The foot pedal 20 is fixed to the top of the movable seat 30 so that the foot pedal 20 can move vertically with the movable seat 30 relative to the mounting frame 10, i.e., the height of the foot pedal 20 can be adjusted vertically. The screw 40 and the locking assembly lock the height position of the foot pedal 20.
[0032] Specifically, the screw 40 extends vertically and is pivotally connected to the mounting bracket 10, allowing the screw 40 to rotate relative to the mounting bracket 10 about its own central axis. A threaded sleeve 31 is provided on the movable seat 30, the cross-sectional size of which is equivalent to that of the screw 40. The threaded sleeve 31 is fitted onto the screw 40, and the internal thread 311 on the inner wall of the threaded sleeve 31 meshes with the external thread on the outside of the screw 40. The locking assembly includes an anti-rotation part and a driving member. The driving member is used to drive the anti-rotation part to move between a first position and a second position. When the anti-rotation part is in the first position, it engages with the screw 40 to limit the degree of freedom of rotation of the screw 40 relative to the mounting bracket 10. When the anti-rotation part is in the second position, it separates from the screw 40 and no longer limits the degree of freedom of rotation of the screw 40 relative to the mounting bracket 10.
[0033] When the height of the foot pedal 20 needs to be adjusted, the user can operate the drive mechanism to move the anti-rotation part to the second position. At this time, the screw 40 has the freedom to rotate relative to the mounting bracket 10. Under these circumstances, the foot pedal 20 can be moved up and down. Since the screw 40 can rotate freely, when the foot pedal 20 is moved up and down, the screw 40 will rotate to adapt to the up and down movement of the threaded sleeve 31. That is, when the foot pedal 20 is moved up and down, the screw 40 will not block the threaded sleeve 31. When the foot pedal 20 is adjusted to the required height position, the user can operate the drive mechanism to move the anti-rotation part to the first position. At this time, the screw 40 is locked and cannot rotate relative to the mounting bracket 10. At this time, the external thread of the screw 40 and the internal thread 311 of the threaded sleeve 31 mesh with each other, so that the threaded sleeve 31 does not have the freedom to move up and down, thereby keeping the foot pedal 20 in a relatively fixed state relative to the mounting bracket 10.
[0034] In this invention, when the screw 40 and the mounting bracket 10 are relatively fixed, the external thread of the screw 40 and the internal thread 311 of the threaded sleeve 31 engage with each other to provide stable support for the foot pedal 20, preventing the foot pedal 20 from abnormally shifting downwards when bearing the downward pressure of the user's legs, thus providing stable support for the user's legs. In addition, the vertical movement of the foot pedal 20 is not restricted, so the height of the foot pedal 20 can be precisely adjusted as needed to better adapt to different user body shapes and different sitting postures. Furthermore, during adjustment, the freedom of rotation of the screw 40 is unlocked, and the screw 40 rotates adaptively, requiring less external force to move the foot pedal 20 up and down, making the vertical adjustment of the foot pedal 20 time-saving and labor-saving.
[0035] It should be noted that in the above structure, the guide groove 11 is used as a guide part, so that the movable seat 30 has the freedom to move relative to the mounting frame 10 in the vertical direction after cooperating with the guide part, and achieves the purpose of preventing the movable seat 30 from rotating relative to the mounting frame 10. In other embodiments, the guide part is not limited to the guide groove 11 mentioned above. For example, a guide post extending vertically can be provided on the mounting frame 10, and the movable seat 30 can be movably sleeved on the guide post. The cross-section of the guide post can be set to square or elliptical. The hole on the movable seat 30 for the guide post to pass through is set to a structure that is consistent with the cross-sectional shape of the guide post, so as to prevent the movable seat 30 from rotating relative to the mounting frame 10. In short, it is only necessary to allow the movable seat 30 to have the freedom to move relative to the mounting frame 10 in the vertical direction.
[0036] In a preferred embodiment, an anti-rotation structure can be provided between the inner wall of the guide groove 11 and the outer peripheral surface of the movable seat 30. This anti-rotation structure prevents the movable seat 30 from rotating relative to the mounting frame 10, improving the stability of the movable seat 30's vertical movement. Specifically, the anti-rotation structure includes a guide rib 12 provided on the inner wall of the guide groove 11 and a guide groove 32 provided on the outer peripheral surface of the movable seat 30. Both the guide rib 12 and the guide groove 32 extend in the vertical direction, and the guide rib 12 is slidably embedded within the guide groove 32. In other embodiments, the guide rib 12 can be provided on the outer peripheral surface of the movable seat 30, and the guide groove 32 can be provided on the inner wall of the guide groove 11.
[0037] To make the overall structure more compact and reduce space occupation, the aforementioned screw 40 is located inside the guide groove 11. A shaft hole 112 is provided on the bottom wall 111 of the guide groove 11. The bottom of the screw 40 passes through the shaft hole 112 so that the screw 40 and the bottom wall 111 are pivotally engaged, thereby allowing the screw 40 to rotate relative to the mounting frame 10 around its own central axis. A locking plate 51 is also provided on the mounting frame 10. The locking plate 51 is located below the bottom wall 111 of the guide groove 11 and is fixedly connected to the bottom of the screw 40, so that the bottom wall 111 is confined between the screw 40 and the locking plate 51. In this way, the locking plate 51 and the screw 40 form an integral whole, and the bottom wall 111 restricts the degree of freedom of the screw 40 to move up and down, ensuring that the screw 40 only has the degree of freedom to rotate relative to the mounting frame 10.
[0038] For ease of assembly, the locking disc 51 can be fixedly connected to the screw 40 with screws. During installation, the screw 40 is inserted into the guide groove 11 from top to bottom, the shaft end of the bottom of the screw 40 is inserted into the shaft hole 112, and then the locking disc 51 is aligned with the shaft hole 112 from below the bottom wall 111. The locking disc 51 is then fixed to the shaft end of the bottom of the screw 40 with screws. The periphery of the locking disc 51 is provided with multiple slots 511 arranged along the axial direction of the locking disc 51. The anti-rotation part is a pin 521 that can be inserted into the slot 511 to engage with the slot 511. After the pin 521 engages with the slot 511, the overall structure composed of the locking disc 51 and the screw 40 cannot rotate relative to the mounting bracket 10. At this time, since the rotational freedom of the screw 40 is limited, the movable seat 30 is locked and cannot move up and down relative to the mounting bracket 10. When the driving member drives the pin 521 away from the locking disc 51 to disengage the pin 521 from the slot 511, the rotational freedom of the screw 40 is no longer limited. Then the screw 40 no longer locks the movable seat 30. When the movable seat 30 moves up and down, the screw 40 rotates adaptively.
[0039] It should be noted that in this utility model, the locking disc 51 can also be integrally formed on the screw 40. For example, multiple slots 511 can be directly provided on the screw 40.
[0040] The aforementioned locking assembly includes a slider 52, which is slidably mounted on the mounting bracket 10, allowing the slider 52 to move laterally relative to the mounting bracket 10. For example, a linear guide pair extending forward and backward or left and right can be provided on the mounting bracket 10, and the slider 52 can be slidably embedded in the linear guide pair, giving the slider 52 the freedom to move forward and backward or left and right relative to the mounting bracket 10. The aforementioned pin 521 is provided at the end of the slider 52 facing the locking disc 51, and the slider 52 is driven to slide along the linear guide pair by a driving member, so that the slider 52 moves closer to or away from the locking disc 51.
[0041] The driving component includes a spring 53 disposed between the slider 52 and the mounting bracket 10, and a knob 50 pivotally connected to the mounting bracket 10. One end of the spring 53 abuts against the mounting bracket 10 and the other end abuts against the slider 52. The spring 53 applies an elastic stress to the slider 52 to keep the pin 521 on the slider 52 always tending to move toward the first position. That is, when there is no other external force, the elastic stress of the spring 53 keeps the pin 521 always engaged with one of the slots 511. The knob 50 is used to drive the slider 52 to move laterally relative to the mounting bracket 10 when it rotates relative to the mounting bracket 10, so that the pin 521 on the slider 52 moves toward the second position. That is, by rotating the knob 50, the slider 52 can be moved to disengage the pin 521 from the slot 511.
[0042] When the seat is in normal use, the elastic stress of the spring 53 keeps the pin 521 in the first position to lock the screw 40. At this time, the position of the foot pedal 20 is fixed, and the screw 40 provides sufficient support for the foot pedal 20 and the movable seat 30. When it is necessary to adjust the height of the foot pedal 20, the user can turn the knob 50 to move the slider 52 away from the locking disc 51, so that the pin 521 disengages from the slot 511, unlocking the screw 40. Then the position of the foot pedal 20 can be adjusted up and down. After adjusting the height of the foot pedal 20 to the desired position, turn the knob 50 again, and the elastic stress of the spring 53 will reset the slider 52. The pin 521 will be inserted into the slot 511 at the corresponding angle to lock the screw 40.
[0043] A lever 541 is provided on the knob 50, and a mating groove 522 is provided on the slider 52. The lever 541 is embedded in the mating groove 522. The end of the mating groove 522 away from the locking disc 51 forms a mating surface 523. When the knob 50 is rotated, it drives the lever 541 to rotate in the mating groove 522. The lever 541 moves the mating surface 523, pushing it away from the locking disc 51. This causes the slider 52 to move away from the locking disc 51 until the length direction of the lever 541 is consistent with the movement direction of the slider 52. This allows the pin 521 to completely disengage from the slot 511. After the height adjustment of the foot pedal 20 is completed, the knob 50 is rotated so that the length direction of the lever 541 is perpendicular to the movement direction of the slider 52. Since the lever 541 no longer obstructs the mating surface 523, the slider 52 returns to its original position under the elastic stress of the spring 53, allowing the pin 521 to be inserted into one of the slots 511.
[0044] It should be noted that, in order to move the slider 52 by using the lever 541, it is not necessary to open a mating groove 522 on the slider 52. It is only necessary to set a mating surface 523 on the slider 52 that can mate with the lever 541.
[0045] In some other embodiments, the driving member does not necessarily use the above-described rotational method to drive the slider 52 to move laterally. It can also use the pressing method to drive the slider 52 to move laterally. For example, the inner end of the driving member abuts against the slider 52, and the slider 52 is pushed by pressing the driving member downward. In short, as long as the driving member can be operated so that the pin 521 on the slider 52 can disengage from the slot 511 after it moves laterally, it is acceptable.
[0046] The mounting bracket 10 has a mounting groove 13. The knob 50 is embedded in the mounting groove 13 so that the knob 50 and the mounting bracket 10 pivotally engage. The knob 50 is equipped with an elastic buckle 56. A positioning groove 14 is provided on the inner wall of the mounting groove 13. The positioning groove 14 engages with the elastic buckle 56. When the knob 50 rotates to the position aligned with the mounting groove 13, the elastic buckle 56 engages with the mounting groove 13, limiting the degree of freedom of the knob 50 to rotate relative to the mounting bracket 10. In this way, when adjusting the height of the foot pedal 20, after rotating the knob 50, the knob 50 can be kept at the corresponding rotation angle, preventing the slider 52 from moving abnormally when adjusting the height of the foot pedal 20.
[0047] The top of the mounting groove 13 is provided with an inwardly extending rib 131. The knob 50 includes a toggle switch 55 and a positioning sleeve 54. The positioning sleeve 54 is fitted over the toggle switch 55. The elastic buckle 56 and the lever 541 are both provided on the positioning sleeve 54. The elastic buckle 56 is arranged radially along the positioning sleeve 54, and the lever 541 is integrally formed on the lower end face of the positioning sleeve 54. The toggle switch 55 protrudes from the outside of the mounting groove 13 for easy operation by the user. The toggle switch 55 and the positioning sleeve 54 are fixed together by screws or other detachable connection methods. The rib 131 is confined between the top surface of the positioning sleeve 54 and the toggle switch 55. The rib 131 is used to limit the degree of freedom of the knob 50 to move up and down, that is, only the knob 50 is allowed to have the degree of freedom of rotation relative to the mounting bracket 10. The knob 50 is divided into two independent parts: a toggle switch 55 and a positioning sleeve 54. During assembly, the positioning sleeve 54 is inserted into the mounting groove 13 from the bottom, and the toggle switch 55 is inserted into the positioning sleeve 54 from the top of the mounting groove 13. Then, the two are fixed together with screws, which facilitates assembly.
[0048] The seat of this utility model includes the height adjustment mechanism of the foot pedal mentioned above. The other structures of the seat are the same as those in the prior art and will not be described in detail here.
[0049] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
