Description

Technical Field

[0001] This utility model relates to the field of seat accessories technology, specifically a rotatable and foldable footrest. Background Technology

[0002] Footrests provide stable support for the user's feet or legs, allowing them to rest comfortably when reclining in a seat. One existing footrest flipping structure relies on the interplay of an elastic element and a snap-fit ​​mechanism to achieve both flipping and securing. Specifically, the elastic element connects the mounting component and the mounting bracket, while the mounting component is connected to the footrest body via a snap-fit ​​mechanism. This snap-fit ​​mechanism includes hooks and slots (or holes). Hooks, which may be elastic protrusions made of metal or plastic, are located on the side or bottom edge of the footrest body, and corresponding slots or holes are present on the mounting component. For example, the hooks may be hook-shaped or T-shaped, and the slots or holes match these shapes to secure the footrest body in the correct position. When installing the footrest, the hooks on the footrest body must be aligned with the slots or holes on the mounting component, and then the footrest body must be pressed down or pushed forward to engage the hooks. This assembly method is relatively complex. In addition, this snap-fit ​​structure relies mainly on the elastic fit between the hook and the slot (or hole) for fixation. Although it can limit the horizontal movement and vertical detachment of the pedal body to a certain extent, it has low stability and poor load-bearing capacity. Utility Model Content

[0003] This invention provides a rotatable and foldable foot pedal with a simple structure and good support stability.

[0004] The rotatable and foldable foot pedal of this utility model includes a bracket slidably mounted under the seat and a foot pedal rotatably mounted on the bracket. The foot pedal has connectors on both sides that are hinged to the bracket. The bracket has a pivot that cooperates with the connectors. The bracket has a protruding limiting block on the outside of the pivot for supporting the foot pedal in the unfolded state. The connector has a semi-circular groove that slides with the limiting block. When the foot pedal is unfolded, one end of the groove abuts against the upper surface of the limiting block and limits its movement. The other end of the groove extends into an extension section, so that when the foot pedal is folded up, the extension section abuts against the limiting block.

[0005] The rotatable and foldable foot pedal utilizes sliding grooves on both sides of the pedal's connectors and limiting blocks on the outer side of the bracket. When the foot pedal is unfolded, it rotates around its axis until the sidewall of the sliding groove tightly abuts against the upper surface of the limiting block, achieving a limiting effect and forming a stable support. This significantly improves the foot pedal's load-bearing capacity, providing reliable foot support for the user. Furthermore, compared to traditional foot pedal flipping structures, this invention eliminates the need for elastic components and the laborious process of aligning hooks with slots, greatly simplifying the locking and limiting structure between the foot pedal and the bracket. This not only reduces material and production costs but also makes the assembly process more convenient and efficient. Workers can quickly complete the installation without special training, improving production efficiency.

[0006] In a preferred embodiment of this utility model, the upper surface of the limiting block is on the same horizontal plane as the center horizontal plane of the rotating shaft.

[0007] As a preferred embodiment of this utility model, the connector includes a body disposed on both sides of the foot pedal and an end cap detachably connected to the body. The end cap is provided with a semi-circular groove that slides with the limit block on the side facing the limit block, and the body is provided with an extension of the groove with the same length as the limit block on the side facing the limit block.

[0008] As a preferred embodiment of this utility model, it also includes a fixing member that can be detachably installed on the bracket, the fixing member being disposed on both sides of the foot pedal, and a limiting block being disposed on the fixing member.

[0009] As a preferred embodiment of this utility model, the bracket includes two opposing crossbars and a rotating shaft that passes through the connector, with the two ends of the rotating shaft connected to the ends of the crossbars in an arc transition.

[0010] As a preferred embodiment of this utility model, it further includes a mounting block connected to the underside of the seat, wherein the mounting block is movably sleeved with the crossbar of the bracket.

[0011] As a preferred embodiment of this utility model, the mounting block is further provided with an extension.

[0012] As a preferred embodiment of this utility model, the rotating shaft is a shaft column protruding on both sides of the bracket.

[0013] As a preferred embodiment of this utility model, the end edge of the shaft column is further provided with a barrier to restrict the left and right movement of the foot pedal.

[0014] As a preferred embodiment of this utility model, the limiting block protrudes from the shaft column or the shaft column enclosure.

[0015] As a preferred embodiment of this utility model, the foot pedal is provided with a number of longitudinally distributed vertical strips or transversely distributed horizontal strips. Attached Figure Description

[0029] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "equipped with," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "several" means one or more, "multiple" means two or more, and "above," "below," and "within" are all understood to include the stated number. Furthermore, the technical features of each embodiment can be arbitrarily combined. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should be considered within the scope of this specification.

[0033] like Figure 1-5As shown, a rotatable and foldable foot pedal includes a bracket 1 slidably mounted under a seat and a foot pedal 2 rotatably mounted on the bracket. The foot pedal 2 has connectors 201 on both sides that are hinged to the bracket. The bracket 1 has a pivot 101 that mates with the connectors. A protruding limiting block 3, located outside the pivot, supports the foot pedal in its unfolded state. The connectors 201 have semi-circular grooves 4 that slidably engage with the limiting blocks. When the foot pedal is unfolded, one end of the groove abuts against the upper surface of the limiting block, providing a limiting effect. The other end of the groove 4 extends into an extension section 5, which abuts against the limiting block when the foot pedal is folded. Through the coordinated action of the grooves on both sides of the foot pedal and the limiting blocks on the outside of the bracket, when the foot pedal is unfolded, it rotates around the pivot until the sidewall of the groove tightly abuts against the upper surface of the limiting block, achieving a limiting effect and forming a stable support. This significantly improves the foot pedal's load-bearing capacity and provides reliable foot support for the user. Compared to traditional foot pedal flip structures, this invention eliminates the need for elastic components and the laborious process of aligning hooks with slots, significantly simplifying the locking and limiting structure between the foot pedal and the bracket. This not only reduces material and production costs and streamlines installation steps but also makes the assembly process more convenient and efficient. Workers can quickly complete the installation without special training, improving production efficiency. Furthermore, since there is no elastic support between the foot pedal and the bracket, users do not need to exert effort to rotate the foot pedal, providing a more convenient user experience.

[0034] Specifically, such as Figure 12 As shown, when the foot pedal is in the extended state (corresponding to...) Figure 12 In state a), the side walls of the sliding grooves on both sides abut against the limiting blocks, thereby achieving limiting and providing stable support for the user. When it is necessary to store the foot pedal, the foot pedal is flipped towards the bracket (from...). Figure 12 (Gradually flip from state a to state b) until the foot pedal is fully flipped over the support, at which point the foot pedal is below the support (e.g., ...). Figure 12 (As shown in state c). During this process, the extended sections of the sliding grooves on both sides of the foot pedal abut against the limiting blocks. The foot pedal's own weight and the reaction force generated by the abutment between the extended sections and the limiting blocks form a balance, allowing the foot pedal to remain stable in the storage position and ensuring that it is not prone to shaking or shifting when not in use.

[0035] The upper surface of the limiting block is on the same horizontal plane as the center plane of the rotating shaft, so that the foot pedal is horizontal and straight when unfolded. In other embodiments, the upper surface of the limiting block may not be on the same horizontal plane as the center plane of the rotating shaft; it may be above or below the center plane of the rotating shaft. Alternatively, the upper surface of the limiting block may be an inclined surface. When the sidewall of the foot pedal's groove abuts against the limiting block, it can create an acute or obtuse angle between the foot pedal and the bracket, rather than a 180-degree angle, thus meeting the needs of different users for different leg or foot support angles. It is understood that the length of the extension section 5 can be set as needed to increase or decrease the foot pedal's retractable angle. This is especially useful for chairs with low seat heights; changing the length of the extension section 5 alters the foot pedal's retractable angle, preventing the foot pedal from hitting the chair legs when retracted.

[0036] It is understood that in some embodiments, the limiting block can be set only on the bracket on one side of the foot pedal, or the limiting blocks can be symmetrically set on the brackets on both sides of the foot pedal to achieve a more reliable and stable support effect.

[0037] like Figure 3 As shown, the connector 201 includes a body 202 disposed on both sides of the foot pedal and an end cap 203 detachably connected to the body. The end cap has a semi-circular groove 4 on the side facing the limiting block, which slides in conjunction with the limiting block. The body has an extension section 5 of the groove, the same length as the limiting block, on the side facing the limiting block. The end cap and body are detachably connected, facilitating the assembly and disassembly of the foot pedal. Specifically, by providing corresponding screw holes on the end cap and body, and fixing them with bolts, screws, or self-tapping screws, the end cap can be quickly and securely installed on the body, thus achieving rapid installation of the foot pedal on the pivot 101. Furthermore, the extension section 5 can also be the same length as the limiting block, making it easier to position the limiting block during installation and further improving assembly efficiency.

[0038] like Figure 3 As shown, it also includes a detachable fastener 6 mounted on the bracket. The fastener is located on both sides of the foot pedal, and the limiting block 3 is mounted on the fastener 6. The fastener adopts a detachable installation method, which facilitates quick installation or replacement as needed and can reduce local wear on the bracket. Specifically, the fastener 6 can be divided into an upper cover 601 and a lower cover 602. Corresponding screw holes are provided on the upper cover and the lower cover, and the upper cover and the lower cover are assembled and fixed to the bracket by bolts, screws or self-tapping screws.

[0039] like Figure 5As shown, the bracket 1 includes two opposing crossbars 102 and a through-connector shaft 101, with both ends of the shaft connected to the ends of the crossbars in an arc transition. In some other embodiments, through holes (not shown) can be provided on the crossbars 102 and / or the shaft 101 of the bracket, and a column (not shown) that can pass through the hole can be provided on the upper cover 601 and / or the lower cover 602. Furthermore, a groove (not shown) can be provided at the other end of the column to fit the column, thereby allowing the fixing member 6 to be more securely installed on the crossbars 102 and the shaft 101.

[0040] Furthermore, such as Figure 1-3 and Figure 6 and Figure 7 As shown, it also includes a mounting block 7 connected to the underside of the seat. The mounting block is movably sleeved with the crossbar 102 of the bracket, allowing the crossbar to move relative to the mounting block. When the foot pedal is needed, the user can grasp the foot pedal and pull it gently. At this time, the crossbar 102 can move accordingly within the mounting block. As the crossbar moves, the foot pedal is slowly pulled out of the bottom area of ​​the seat (e.g., Figure 6 State a to Figure 6 (State b) Then, the user can rotate and unfold the foot pedal (e.g.) Figure 6 State b to Figure 6 (State c) until the foot pedal is positioned so that its side walls of the sliding grooves on both sides abut against the limiting blocks, preventing further rotation. At this point, the user places their legs or feet on the unfolded foot pedal for stable support. When retracting the foot pedal, the process is reversed; the foot pedal is flipped in the opposite direction from its unfolded state (e.g., ...). Figure 6 State c to Figure 6 (State d) After the foot pedal is flipped into position (e.g.) Figure 6 State d), that is, until the foot pedal rotates towards the bracket and passes the bracket, at which point the foot pedal is located below the bracket, and the side walls of the extended sections of the sliding grooves on both sides of the foot pedal abut against the limiting block, and cannot continue to rotate, the user can push the foot pedal to move the crossbar 102 relative to the mounting block again, gradually pushing the foot pedal back into the storage space under the seat (e.g. Figure 6 State d to Figure 6 State a).

[0041] In some embodiments, the mounting block 7 may be a cylinder, such as... Figure 8 and Figure 9As shown, this shape and structure is simple and easy to manufacture, making it suitable for seat cushions with a large installation space at the bottom, such as those filled with sponge, sponge plus latex, or latex. However, in practical applications, some seat cushions use mesh fabric. To allow more open space for breathability, these cushions have a relatively small spacing between the mounting blocks, which also limits the spacing of the brackets, thus making it difficult to provide enough space for installing the footrest. Therefore, the mounting block 7 also has an extension 701, as shown in some embodiments, such as... Figure 10 As shown, the extension 701 extends from the main body of the mounting block 7, effectively increasing the spacing of the brackets. In this way, even when the spacing between the seat cushion mounting blocks is small, the brackets can still maintain a suitable spacing, providing ample space for the footrest installation. This ensures the footrest can be stably and reliably installed under the seat, meeting the needs of different seat cushion types and also applicable to smaller seat cushions, improving versatility and applicability. Of course, for different types of seat cushions (such as those with padding or mesh fabric) and different sizes, either a cylindrical mounting block 7 or a mounting block 7 with the extension 701 can be used; the choice is flexible and not limited here. Furthermore, it is understood that the extension of the mounting block 7 can extend not only laterally but also longitudinally or a combination of both. By reasonably setting the extension height, when the footrest 2 is in the unfolded state, its horizontal plane height can form an appropriate difference with the seat cushion height, preventing the feet or legs from being placed too high or too low on the footrest, thereby improving comfort.

[0042] In other embodiments, the foot pedal 2 may also adopt a frame-shaped mesh structure, such as... Figure 11 As shown in a and b, by fixing the mesh material 8 to the frame structure 9, a flat and taut mesh surface is formed, which not only provides good flexibility and breathability, but also produces a cushioning effect by the elastic deformation of the mesh surface when pressure is applied to the feet, thereby improving riding comfort.

[0043] On the other hand, the foot pedal 2 can also be integrally injection molded. The foot pedal can also have several longitudinally distributed vertical strips 204 or transversely distributed horizontal strips. When the foot is placed on the foot pedal, these vertical or horizontal strips can absorb and disperse the pressure applied by the foot through their own deformation, playing a cushioning role and reducing the hard impact between the foot and the foot pedal, further improving the comfort of use. Furthermore, both the longitudinally distributed vertical strips and the transversely distributed horizontal strips are arranged in an intermittent manner, that is, adjacent vertical strips are independent of each other and horizontal strips are not interconnected. This layout can significantly enhance the overall cushioning performance and further improve its cushioning effect. Further improvements include the provision of interconnected through holes 10 on the side of the foot pedal near the pivot and on both sides, thereby further increasing the cushioning force, such as... Figure 9 and Figure 10 As shown.

[0044] In other embodiments, the pivot is not limited to a round rod structure that runs through the connectors on both sides of the foot pedal; it can also be a shaft column protruding from both sides of the bracket, such as... Figure 13 As shown, the foot pedal can rotate flexibly by rotatably connecting the connectors on both sides to the shaft. Furthermore, the end edge of the shaft also has a protruding guard 103 to limit the left and right movement of the foot pedal, preventing the foot pedal from disengaging during rotation.

[0045] Furthermore, the limiting block 3 protrudes from the shaft column or the shaft column enclosure 103. In addition, in some embodiments, the shaft column and / or the shaft column enclosure 103 can be integrally formed with the crossbar 102, or the shaft column and / or the shaft column enclosure 103 can be integrally formed with the fixing member 6 and designed as a detachable installation structure with upper and lower halves, thereby facilitating installation and fixing.
