Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to an anti-pinch structure, a footrest, and furniture. Background Technology

[0002] In the field of single-arm chair furniture, the anti-pinch safety of the footrest is an important design consideration. Current technology generally employs a fixed anti-pinch structure, where the anti-pinch plate is rigidly mounted on the footrest frame. This fixed design has an inherent drawback: because the position of the anti-pinch plate is static and cannot adjust with the movement of the footrest panel, changing gaps will occur between the internal frame and moving parts during the opening and closing of the footrest. The fixed anti-pinch plate cannot continuously and effectively block these dynamically changing danger areas, resulting in blind spots in anti-pinch protection and poor protective effect. Utility Model Content

[0003] The embodiments of this utility model provide an anti-pinch structure, a footrest, and furniture, which solves the technical problem that existing fixed anti-pinch structures cannot continuously and effectively block dynamic gaps during the opening and closing of the footrest.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an anti-pinch structure, the anti-pinch structure comprising a base, at least one first anti-pinch piece, at least one second anti-pinch piece, and a driving mechanism, wherein the first anti-pinch piece is fixedly connected to the base, and the driving mechanism is connected between the base and the second anti-pinch piece; wherein the driving mechanism is configured to: in response to the movement of the base, drive the second anti-pinch piece to move relative to the base to dynamically block the gap.

[0005] In some embodiments, the drive mechanism includes a link, one end of which is rotatably connected to the base, and the other end of which is rotatably connected to the second anti-pinch plate.

[0006] In some embodiments, the connecting rod is located in the inner space of the second anti-pinch plate.

[0007] In some embodiments, the inner side of the second anti-pinch plate is provided with a connecting portion, and the end of the connecting rod is connected to the connecting portion via a pivot.

[0008] In some embodiments, the linkage is configured to synchronize the movement of the second anti-pinch plate with the movement of the base, so that the second anti-pinch plate can continuously block the gap during the movement stroke of the base.

[0009] In some embodiments, the number of the first anti-pinch plates is two, the number of the second anti-pinch plates is one, and the two first anti-pinch plates and the one second anti-pinch plate are arranged sequentially along the extension direction of the base.

[0010] In some embodiments, the two first anti-pinch plates and the one second anti-pinch plate are arranged in a stepped manner.

[0011] In some embodiments, when the anti-pinch structure is fully deployed, the two first anti-pinch plates and the one second anti-pinch plate together form a streamlined outer surface.

[0012] According to another aspect of this application, an embodiment of the present invention provides a footrest, the footrest including the above-described anti-pinch structure; wherein the base is the frame of the footrest, and the drive mechanism is configured to drive the second anti-pinch piece to move when the footrest is opened and closed, so as to dynamically block the gap generated during the movement of the footrest.

[0013] According to another aspect of this application, an embodiment of the present invention provides a piece of furniture that includes the aforementioned footrest.

[0014] Compared with the prior art, the anti-pinch structure of this utility model has at least the following beneficial effects: The anti-pinch structure provided by this utility model includes a base, at least one first anti-pinch plate, at least one second anti-pinch plate, and a driving mechanism. The first anti-pinch plate is fixedly connected to the base, and the driving mechanism is connected between the base and the second anti-pinch plate. The driving mechanism is configured to drive the second anti-pinch plate to move relative to the base in response to the movement of the base, so as to dynamically block the gap.

[0015] This invention effectively solves the problems in the prior art by introducing a system consisting of a base, a first anti-pinch plate, a second anti-pinch plate, and a drive mechanism. The solution lies in the fact that it no longer relies entirely on static anti-pinch plates, but instead uses a drive mechanism to make the second anti-pinch plate a dynamically responsive component. More specifically, when the base moves, causing a change in the frame gap, the drive mechanism drives the second anti-pinch plate to move accordingly, ensuring it always accurately aligns with and blocks the dynamically changing area. This achieves full coverage of anti-pinch protection throughout the entire opening and closing process of the footrest, eliminating the blind spots caused by the inability of fixed anti-pinch plates to adapt to changing gaps.

[0016] The footrest provided by this utility model is designed based on the above-mentioned anti-pinch structure. Its beneficial effects are the same as those of the above-mentioned anti-pinch structure, and will not be repeated here.

[0017] The furniture provided by this utility model is designed based on the above-mentioned footrest, and its beneficial effects are the same as those of the above-mentioned footrest, which will not be repeated here.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1 This embodiment provides an anti-pinch structure, such as Figures 1-6 As shown, the anti-pinch structure includes a base 1, at least one first anti-pinch plate 2, at least one second anti-pinch plate 3, and a driving mechanism 4. The first anti-pinch plate 2 is fixedly connected to the base 1, and the driving mechanism 4 is connected between the base 1 and the second anti-pinch plate 3. The driving mechanism 4 is configured to drive the second anti-pinch plate 3 to move relative to the base 1 in response to the movement of the base 1, so as to dynamically block the gap.

[0026] In the anti-pinch structure, the base 1 serves as the support and moving frame of the entire device. The first anti-pinch plate 2 is directly fixedly connected to the base 1, and its position is stationary relative to the base 1. The second anti-pinch plate 3 is linked to the base 1 through the drive mechanism 4. More specifically, the two ends of the drive mechanism 4 are rotatably connected to the base 1 and the second anti-pinch plate 3, respectively, thereby transmitting the motion of the base 1 and converting it into a specific motion of the second anti-pinch plate 3 relative to the base 1.

[0027] The base 1 serves as the mounting foundation for the entire anti-pinch structure and the main body for performing opening and closing movements. The first anti-pinch plate 2 is responsible for blocking certain gap areas that are always present or have fixed positions during the movement of the base 1 through its fixed installation. The second anti-pinch plate 3 moves under the drive of the drive mechanism 4 and is specifically used to dynamically block those critical gaps that change with the movement of the base 1. The core function of the drive mechanism 4 is as a transmission component, which responds to and follows the movement of the base 1, thereby precisely driving the second anti-pinch plate 3 to produce coordinated movement.

[0028] When the base 1 begins to move, for example, when the footrest opens or closes, the fixedly installed first anti-pinch plate 2 moves accordingly and continuously covers a portion of the gap. At the same time, the drive mechanism 4 immediately senses the change in the movement state of the base 1 and begins to work, driving the second anti-pinch plate 3 to make a compensatory movement relative to the moving base 1. Furthermore, this cooperation ensures that the area originally covered by the first anti-pinch plate 2 is maintained throughout the entire movement stroke of the base 1, while the gaps that open and close are timely and continuously blocked by the moving second anti-pinch plate 3. The two work together to form a blind-spot-free anti-pinch protection surface.

[0029] This embodiment effectively solves the problems in the prior art by introducing a system consisting of a base 1, a first anti-pinch plate 2, a second anti-pinch plate 3, and a drive mechanism 4. The solution lies in the fact that it no longer relies entirely on static anti-pinch plates, but instead uses the drive mechanism 4 to make the second anti-pinch plate 3 a dynamically responsive component. More specifically, when the base 1 moves, causing a change in the frame gap, the drive mechanism 4 drives the second anti-pinch plate 3 to move accordingly, ensuring that it always accurately aligns with and blocks the dynamically changing area. This achieves full coverage of anti-pinch protection throughout the entire opening and closing process of the footrest, eliminating the blind spots caused by the inability of fixed anti-pinch plates to adapt to changing gaps.

[0030] In a specific embodiment, such as Figure 1 , Figure 3 as well as Figure 5 As shown, the driving mechanism 4 includes a connecting rod, one end of which is rotatably connected to the base 1, and the other end of which is rotatably connected to the second anti-pinch plate 3.

[0031] The drive mechanism 4 specifically includes a linkage. One end of the linkage is rotatably connected to the base 1, and the other end is rotatably connected to the second anti-pinch plate 3. This connection allows the linkage to directly transmit the movement of the base 1 to the second anti-pinch plate 3, thereby driving the second anti-pinch plate 3 to rotate relative to the base 1. More specifically, during the opening and closing of the footrest, when the base 1, as the main moving body, shifts, the linkage immediately responds and drives the second anti-pinch plate 3 to move synchronously. This rotation adjusts the position and angle of the second anti-pinch plate 3, ensuring that it can continuously align with and block the changing gap area during movement. The effect of this design is that it uses the simple mechanical principle of the linkage to achieve precise linkage between the movement of the second anti-pinch plate 3 and the base 1, thereby dynamically covering the dangerous gap throughout the entire opening and closing stroke of the footrest. This eliminates the blind spots left by traditional fixed anti-pinch plates that cannot move with the footrest, not only improving the reliability of anti-pinch safety but also reducing the complexity of the mechanism due to the simplicity of the linkage structure, while also helping to maintain a smooth overall appearance.

[0032] In a specific embodiment, the connecting rod is located in the inner space of the second anti-pinch plate 3.

[0033] "The connecting rod is located in the inner space of the second anti-pinch plate 3" means that the entire connecting rod mechanism is designed and housed in the space on the side of the second anti-pinch plate 3 facing the base 1. More specifically, when the entire anti-pinch structure is viewed from the outside, the connecting rod that plays a driving role is concealed by the second anti-pinch plate 3 itself; it is hidden inside the second anti-pinch plate 3, rather than exposed on the outside or side of the anti-pinch plate. This layout means that under normal use and viewing angle of the footrest, it is difficult for people to see the connecting rod directly; it becomes a built-in, invisible driving component. The effect of this design is very significant. First, it greatly enhances the overall aesthetics of the product, because all the complex mechanical connections are cleverly hidden, making the exposed anti-pinch plate look very neat and streamlined. Furthermore, placing the connecting rod in the inner space of the second anti-pinch plate 3 can also effectively prevent the connecting rod from accidentally interfering with or colliding with the user's limbs or external objects during movement, thereby enhancing the safety of use. At the same time, this built-in layout also provides a protected working environment for the connecting rod itself, reducing the risk of mechanism jamming caused by external dust accumulation or foreign object intrusion, and helping to ensure the reliability and stability of the drive mechanism 4 in long-term operation.

[0034] In a specific embodiment, the inner side of the second anti-pinch plate 3 is provided with a connecting part, and the end of the connecting rod is connected to the connecting part through a rotating shaft.

[0035] Specifically, a connecting part is specially designed on the inward-facing side of the second anti-pinch plate 3. This connecting part is either part of the main structure of the second anti-pinch plate 3 or an additional component firmly connected to it. The end of the connecting rod is movably connected to this connecting part via a pivot, meaning that the connecting rod can rotate around the center line of the pivot. This connection method provides a stable and reliable rotational fulcrum for the movement of the second anti-pinch plate 3 and ensures precise and smooth power transmission. When the base 1 moves and drives the second anti-pinch plate 3 through the connecting rod, the pivot connection allows the second anti-pinch plate 3 to rotate stably along the expected trajectory, thereby precisely adjusting its position to continuously block the gap. In addition, placing the connecting part on the inner side of the second anti-pinch plate 3 allows the entire transmission component to be hidden, without compromising the overall integrity and smoothness of the appearance. This design ensures reliable anti-pinch function while also taking into account the aesthetics of the product's shape.

[0036] In a specific embodiment, the connecting rod is configured to synchronize the movement of the second anti-pinch plate 3 with the movement of the base 1, so that the second anti-pinch plate 3 can continuously block the gap during the movement stroke of the base 1.

[0037] The length, shape, and connection points of the connecting rod with the base 1 and the second anti-pinch plate 3 are specifically calculated. This ensures that any movement of the base 1, whether unfolding or retracting, is immediately and proportionally translated into rotation of the second anti-pinch plate 3 via the connecting rod. More specifically, as the base 1 moves during its stroke, it pulls or pushes the connecting rod, which converts this linear or arc-shaped displacement into rotational motion of the second anti-pinch plate 3, thereby adjusting the tilt angle and position of the second anti-pinch plate 3 in real time. This close following relationship ensures that at every different position of the base 1, the second anti-pinch plate 3 moves precisely to a position that can cover the gap between itself and surrounding components. This design fundamentally improves the reliability of protection, transforming anti-pinch protection from a static, limited concept into a dynamic, full-process safety mechanism. Because the second anti-pinch plate 3 can move synchronously with the base 1, there is no protective gap at any stage of the footrest's opening and closing process, completely eliminating the risk of user injury due to changes in gap.

[0038] In a specific embodiment, such as Figure 1 , Figure 3 as well as Figure 5 As shown, there are two first anti-pinch plates 2 and one second anti-pinch plate 3, and the two first anti-pinch plates 2 and the one second anti-pinch plate 3 are arranged sequentially along the extension direction of the base 1.

[0039] This embodiment specifically includes two first anti-pinch plates 2 and one second anti-pinch plate 3, arranged sequentially along the extension direction of the base 1. This means that along the length of the base 1, the two first anti-pinch plates 2 are located at specific positions, while the movable second anti-pinch plates 3 are positioned adjacent to them, forming a continuous anti-pinch coverage area. More specifically, this sequential arrangement allows each anti-pinch plate to be responsible for gap protection in different sections of the base 1. The two first anti-pinch plates 2 are fixedly connected to cover the relatively stable gap portions, while the second anti-pinch plates 3, driven by the drive mechanism 4, specifically address gap areas that change during movement. The effect of this layout is primarily reflected in structural simplification; it achieves comprehensive protection with fewer components, reducing the number of parts and assembly complexity compared to traditional multi-piece designs, thereby helping to reduce production costs and improve reliability. Furthermore, due to the reduced number and orderly arrangement of the anti-pinch plates, they can be better integrated into the overall outline of the base 1, avoiding visual clutter and giving the footrest a smoother and more harmonious appearance. While ensuring safety functions, this significantly enhances the product's aesthetics, thereby better meeting the design needs of modern homes.

[0040] In a specific embodiment, the two first anti-pinch plates 2 and the one second anti-pinch plate 3 are arranged in a stepped manner.

[0041] Two first anti-pinch plates 2 and one second anti-pinch plate 3 are arranged in a stepped manner. This means they are not simply arranged side-by-side, but rather form a staggered or layered layout along the extension direction of the base 1, like steps. This arrangement differentiates each anti-pinch plate in spatial position, with the first anti-pinch plate 2 and the second anti-pinch plate 3 presenting a progressive sense of layering, thus more naturally covering gaps in different areas during footrest movement. The effect is first reflected in aesthetics; the stepped design eliminates the visual redundancy and disharmony of traditional multi-piece anti-pinch plate arrangements, instead creating a simple and smooth outline, significantly enhancing the overall appearance of the product. Furthermore, this layered arrangement helps optimize the coordination of movement between the anti-pinch plates, ensuring that when the second anti-pinch plate 3 moves under the drive mechanism 4, it avoids mechanical interference with the fixed first anti-pinch plate 2, thereby guaranteeing the stable operation of the anti-pinch function and the long-term reliability of the structure. At the same time, this compact and orderly layout also makes the anti-pinch structure easier to adapt to various footrest shapes.

[0042] In a specific embodiment, when the anti-pinch structure is fully deployed, such as Figure 5 As shown, the two first anti-pinch plates 2 and the one second anti-pinch plate 3 together form a streamlined outer surface.

[0043] When the entire device is fully extended, the two first anti-pinch plates 2 and the one second anti-pinch plate 3 combine through their shape and arrangement to form a smooth and continuous outer surface. This streamlined design means that there are no obvious seams or abrupt transitions between the anti-pinch plates, but rather a softly curved contour, similar to a natural, flowing curve. More specifically, the construction of this outer surface relies on the precise layout of the first anti-pinch plates 2 and the second anti-pinch plates 3 on the base 1, allowing them to connect seamlessly when extended. The streamlined outer surface eliminates the clutter and disharmony caused by multiple components in traditional anti-pinch structures, improving the overall aesthetics and better meeting users' high demands for the appearance of home products. This smooth outer surface not only reduces the possibility of dust or debris accumulation, facilitating daily cleaning and maintenance, but also provides a more comfortable experience for users when touching it.

[0044] When the anti-pinch structure provided in Example 1 is applied to a footrest, its specific working process is as follows: As the footrest unfolds or retracts, the base 1, serving as the installation foundation and moving frame of the entire structure, moves accordingly. The two first anti-pinch plates 2, fixedly connected to the base 1, move synchronously with the base 1, continuously blocking the relatively fixed gap areas on the base 1. Simultaneously, the drive mechanism 4, connected to the base 1 and the second anti-pinch plate 3, begins to function. Specifically, one end of the connecting rod in the drive mechanism 4 is connected to the base 1, and the other end is connected to the connecting part located inside the second anti-pinch plate 3, achieving a rotatable connection via a pivot. The movement of the base 1 forces the connecting rod to swing. Since the connecting rod is configured to move synchronously with the base 1, it then drives the second anti-pinch plate 3 to rotate precisely relative to the base 1. This movement process allows the second anti-pinch plate 3 to adjust its position and angle in real time, thereby accurately covering the critical gaps that dynamically change with the movement of the base 1. Throughout the entire movement, the two first anti-pinch plates 2 and one second anti-pinch plate 3 maintain a stepped arrangement, working together to form a continuous and seamless anti-pinch protection surface. When the footrest is fully extended, the three anti-pinch plates eventually form a smooth, streamlined outer surface. This not only ensures the effectiveness of the anti-pinch function throughout the entire process and eliminates blind spots in protection, but also makes the entire footrest structure present a simple and beautiful visual form.

[0045] Example 2 This embodiment provides a footrest, which includes the anti-pinch structure described in Embodiment 1; wherein, the base 1 is the frame of the footrest, and the drive mechanism 4 is configured to drive the second anti-pinch piece 3 to move when the footrest is opened and closed, so as to dynamically block the gap generated during the movement of the footrest.

[0046] The core of the footrest provided in this embodiment lies in integrating the entire anti-pinch structure of Embodiment 1, and specifically defining the base 1 as the frame of the footrest itself. This makes the anti-pinch structure and the footrest form a functionally unified whole. When the footrest performs an opening and closing action, its frame, i.e., the base 1, begins to move. At this time, the drive mechanism 4 immediately responds to this action, driving the second anti-pinch plate 3 to move relative to the footrest frame through internal linkage transmission. More specifically, this movement process allows the second anti-pinch plate 3 to adjust its position in real time, accurately covering the gap area that changes size as the footrest panel opens and closes.

[0047] From the perspective of the footrest as a whole, this design fundamentally improves safety and user experience. It completely solves the blind spot problem inherent in traditional footrests with fixed anti-pinch plates, ensuring that the user's hands and feet will not be pinched by dynamically changing frame gaps at any opening angle. Furthermore, because this anti-pinch structure uses a streamlined number of anti-pinch plates and achieves smooth operation, it not only does not significantly increase the burden on the footrest's movement, thus maintaining ease and flexibility in the opening and closing process, but also greatly optimizes the footrest's appearance through a stepped arrangement and a streamlined outer surface, showcasing a simple and modern aesthetic while ensuring safety.

[0048] Example 3 This embodiment provides a type of furniture, such as... Figures 7-10 As shown, the furniture includes the footrest described in Embodiment 2.

[0049] At the furniture product level, its core feature lies in the integration of the footrest described in Embodiment 2. This means that the footrest and its advanced internal anti-pinch structure have become an inherent component of the furniture. Specifically, the footrest itself includes an anti-pinch structure with the base 1 serving as the footrest frame, and is equipped with a drive mechanism 4 that can drive the second anti-pinch plate 3 to move when the footrest is opened and closed.

[0050] From a holistic furniture perspective, this integration brings several significant benefits. The most direct effect is a substantial improvement in furniture safety. It fundamentally eliminates the risk of users being pinched by gaps between moving parts when extending or retracting the footrest, as the second anti-pinch plate 3 dynamically follows the footrest's movement and constantly shields the danger zone, providing more comprehensive protection for home users, especially children and the elderly. Furthermore, due to the streamlined and sleek design of the footrest's anti-pinch structure, the overall furniture design sheds the bulkiness and mechanical feel of traditional anti-pinch devices, resulting in a more harmonious and modern style.

[0051] Furthermore, the furniture in this embodiment can be a single chair, such as a common leisure chair, functional chair, or recliner. This type of furniture is typically equipped with a retractable footrest, making it the most typical and direct application of the anti-pinch structure. Further, it integrates the footrest from Embodiment 2, which features dynamic anti-pinch functionality, a streamlined design, and flexible operation, as a core component into the overall design of the single chair. This allows the single chair to not only provide basic sitting and reclining functions but also a crucial enhanced safety feature: users no longer need to worry about their feet or clothing being caught in the mechanical gaps when frequently opening and closing the footrest. Simultaneously, due to the simple structure and aesthetically pleasing appearance of the footrest, it helps to enhance the overall design and product quality of the single chair, solving the problem of traditional single chairs appearing bulky or having a disjointed design in the footrest area due to the anti-pinch structure. Ultimately, it achieves a unity of safety, aesthetics, and comfort, significantly enhancing the single chair's competitiveness in the market.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
