Description

Technical Field

[0001] The present application relates to the field of furniture, and in particular to a folding chair. Background Art

[0002] Existing folding chairs have a foldable function, which is achieved by the relative rotation between the chair back and the chair plate. Since the chair back and the chair plate can rotate relative to each other, the chair back may rotate due to user error during use, causing inconvenience to the user. Utility Model Content

[0003] The purpose of the present application is to provide a folding chair to improve the problem of the chair back rotating relative to the chair plate during use of the folding chair.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application provides a folding chair, comprising a seat plate and a backrest; the seat plate comprises a first side rod extending toward the backrest; the backrest is rotatably connected to an end of the first side rod, and in the extension direction of the first side rod, there is a gap between the backrest and the first side rod to allow the backrest and the first side rod to rotate relative to each other; the gap is detachably provided with a stopper, and the stopper comprises a rigid first section, and the first section is located in the gap to limit the relative rotation of the first side rod and the backrest.

[0006] In the above technical solution, the gap between the seat back and the first side bar allows the seat back and the first side bar to rotate relative to each other, that is, the seat plate and the seat back rotate relative to each other, thereby achieving the folding or unfolding process of the folding chair. Because the first section of the stopper is rigid and not easily deformed, when the first section of the stopper is positioned in the gap between the seat back and the first side bar, the size of the gap can be reduced, thereby limiting the relative rotation angle between the seat plate and the seat back, thereby reducing the inconvenience caused to the user by the relative rotation of the seat plate and the seat back during use of the folding chair.

[0007] In some optional embodiments, the locking member further includes a second section connected to the first section, and the locking member is configured such that when the first section is located in the gap, the second section is restricted outside the gap.

[0008] In the above technical solution, since the second section is restricted outside the gap when the first section is located in the gap, the first section can be easily removed from the gap through the second section, and the stopper can also be easily installed or removed.

[0009] In some optional embodiments, the first section and the second section have an included angle, so that when the first section is located in the gap, the second section is located on the upper side of the first side rod.

[0010] In the above technical solution, when the first section is located in the gap, the second section is located on the upper side of the first side rod. On the one hand, the first side rod contacts the second section, thereby positioning the installation position of the first section. On the other hand, it is convenient to remove the first section from the gap through the second section.

[0011] In some optional embodiments, the thickness of the first segment at the end away from the second segment is smaller.

[0012] When the first section of the stopper is installed into the gap, the end of the first section away from the second section enters the gap first. Therefore, when the thickness of the end of the first section away from the second section is smaller, the first section can be installed into the gap more conveniently.

[0013] In some optional embodiments, the first section and the second section are perpendicular to each other, and the locking member is an L-shaped structural member.

[0014] In the above technical solution, since the stopper is an L-shaped structural member, the first section of the stopper is perpendicular to the second section. Therefore, when the first section is located in the gap, the second section can better contact the upper side surface of the first side rod, making the stopper more stable.

[0015] In some optional embodiments, the first section and the second section have the same thickness, and both the first section and the second section are rigid structural members.

[0016] In the above technical solution, since the first and second sections are of equal thickness and both are rigid structures, they can be positioned within the gap between the first side bar and the connector, thereby limiting the rotation of the chair back relative to the seat plate. This eliminates the need to distinguish between the first and second sections during use, making the stopper more convenient to use.

[0017] In some optional embodiments, it further includes a supporting foot, which is fixedly connected to the chair plate.

[0018] In some optional embodiments, the first side rod includes a rod-shaped structural member and a shell-shaped structural member, wherein the shell-shaped structural member is a plastic structural member and surrounds the end of the rod-shaped structural member facing the chair back.

[0019] In the above technical solution, the end of the first side rod facing the chair back has a shell-like structure, and the shell-like structure is a plastic structure. The hardness of the plastic structure is low and will not leave a large mark on the stopper after being squeezed with the stopper.

[0020] In some optional embodiments, the chair back includes a back panel and a connecting member, the connecting member includes a first side panel and a second side panel that are opposite to each other, the first side rod is located between the first side panel and the second side panel, and a rotating shaft is sequentially provided between the first side panel, the first side rod, and the second side panel, so that the first side rod can rotate relative to the first side panel and the second side panel;

[0021] The ends of the first side panel and the second side panel are connected to the back panel, and the gap is located between the back panel and the first side rod; or, the connecting member further includes a connecting plate, which connects the first side panel and the second side panel, and the connecting plate is also connected to the back panel, and the gap is located between the connecting plate and the first side rod.

[0022] In the above technical solution, the connecting part includes a first side panel and a second side panel, the first side rod is located between the first side panel and the second side panel, and the first side rod is rotatably connected to the first side panel and the second side panel through a rotating shaft, so that the forces on both sides of the first side rod are more balanced, making it easier to rotate between the chair panel and the chair back.

[0023] In some optional embodiments, a vertically continuous area is formed between the first side panel and the second side panel, so that the end of the first side rod can be rotated in or out between the first side panel and the second side panel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0035] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] Folding chairs in the prior art have the advantage of being easy to store. These chairs comprise a seat plate and a backrest that can rotate relative to each other. The seat plate is the structural component that directly contacts the user's buttocks, while the backrest is the structural component that directly contacts the user's back. When the chair is to be stored, the backrest can be rotated toward the upper surface of the seat plate. When the chair is to be unfolded, the backrest can be rotated away from the upper surface of the seat plate.

[0037] The inventor of this application found that during the use of the existing folding chair, since the chair plate 100 and the chair back 200 can rotate relative to each other ( Figure 1 The position of the middle back panel shown by the dotted line is the position through which the chair board 100 passes during rotation). Therefore, in actual use, after a force is applied to the chair back 200 (the force is applied to the side of the upper surface of the chair back 200 facing away from the chair board 100), the chair back 200 can easily rotate relative to the chair board 100. After the rotation, the chair back 200 will continue to rotate toward the upper surface of the chair board 100 to a folded state under the action of gravity. The user needs to unfold the folding chair before using it, which brings inconvenience to the user's operation.

[0038] Based on this, the present application provides a folding chair, such as Figure 1 As shown, it includes a chair plate 100 and a chair back 200 that can rotate relative to each other. Figure 4 The chair plate 100 includes a first side rod 110 extending toward the chair back 200. The first side rod 110 is rotatably connected to the connecting member 210, thereby realizing relative rotation between the chair plate 100 and the chair back 200. Figure 2 As shown, in the extension direction of the first side rod 110, there is a gap between the first side rod 110 and the chair back 200. This gap provides space for the relative rotation between the chair back 200 and the seat plate 100, so that the chair back 200 and the seat plate 100 can rotate. That is, due to the existence of this gap, the relative rotation between the connecting rod and the first side rod 110 can be carried out. Therefore, in the embodiment provided by the present application, as shown in FIG. Figure 2 and Figure 3As shown, a stopper 300 is also removably disposed in the gap. The stopper 300 has a rigid first section 310. When the first section 310 is located in the gap, it can limit the relative rotation between the first side bar 110 and the chair back 200. Because the stopper 300 is removably disposed in the gap, it can be removed when the folding chair needs to be folded and stored. After unfolding the folding chair, the first section 310 of the stopper 300 is inserted into the gap before use. Restricting the relative rotation between the first side bar 110 and the chair back 200 means that, compared to a situation where the first section 310 of the stopper 300 is not disposed in the gap, the first section 310 of the stopper 300 is disposed in the gap, thereby reducing the relative rotation angle between the chair panel 100 and the chair back 200.

[0039] In the above technical solution, since the first section 310 of the stopper 300 is rigid and not easy to deform, when the first section 310 of the stopper 300 is set in the gap between the chair back 200 and the first side rod 110, the size of the gap can be reduced, thereby limiting the relative rotation angle between the chair panels 100 and the chair panels 100, so as to reduce the inconvenience caused to the user by the relative rotation of the chair panel 100 and the chair back 200 during the use of the folding chair.

[0040] In some embodiments, the locking member 300 can completely fill the gap in the direction of extension of the first side bar 110. That is, when the first section 310 of the locking member 300 fits within the gap, the size of the locking member 300 along the direction of extension of the first side bar 110 is substantially equal to the size of the gap. In other embodiments, the first section 310 of the locking member 300 may not completely fill the gap. That is, when the first section 310 of the locking member 300 fits within the gap, the size of the locking member 300 along the direction of extension of the first side bar 110 is smaller than the size of the gap. The user can choose whether to completely fill the gap in the direction of extension of the first side bar 110 with the locking member 300 as needed.

[0041] In some embodiments, the first section 310 of the locking member 300 may be a structural member made of metal material, or may have a metal structure inside and a plastic structure outside, or the first section 310 as a whole may be a plastic structural member with a certain rigidity.

[0042] In some embodiments, the locking member 300 further includes a second section 320 connected to the first section 310. When the first section 310 is located within the gap, the second section 320 is restrained outside the gap. It is readily understood that when the first section 310 is located within the gap, the second section 320 of the locking member 300 is located outside the gap, making it easier for a user to remove the first section 310 of the locking member 300 from the gap via the second section 320, thus facilitating disassembly of the locking member 300.

[0043] In some embodiments, the first section 310 and the second section 320 of the locking member 300 extend in the same direction, that is, there is no angle between the first section 310 and the second section 320. In this embodiment, by making the second section 320 larger than the first section 310, when the first section 310 is located within the gap, the second section 320 is restricted from the gap.

[0044] In some embodiments, the first section 310 and the second section 320 of the stopper 300 may extend in different directions, that is, the first section 310 and the second section 320 may have an angle. Figure 2 and Figure 3 As shown, since the first section 310 and the second section 320 have an included angle, when the first section 310 is located in the gap between the chair back 200 and the first side rod 110 , the second section 320 can be located on the upper side of the first side rod 110 and thus always outside the gap.

[0045] Furthermore, the angle between the first section 310 and the second section 320 can be 30°, 45°, 60°, 90°, etc. When the angle between the first section 310 and the second section 320 is 90°, the first section 310 and the second section 320 are perpendicular to each other, and the stopper 300 is an L-shaped structure. The L-shaped structure of the stopper 300 allows the surface of the second section 320 to mate with the upper surface of the first side bar 110, allowing the stopper 300 to better integrate into the chair panel 100 without protrusion, resulting in a better visual effect and avoiding the negative user experience caused by the protruding stopper 300.

[0046] To facilitate installation of the first section 310 within the gap, in some embodiments, the thickness of the first section 310 at the end facing away from the second section 320 is reduced. The thickness of the first section 310 is defined as the dimension of the first section 310 in the extending direction of the first sidebar 110 when the first section 310 is within the gap. As will be appreciated, during installation of the stopper 300, the portion of the first section 310 facing away from the second section 320 faces the gap. Therefore, the relative positioning of the first section 310 and the gap is not easily adjusted, resulting in inconvenient installation of the stopper 300. Because the thickness of the first section 310 at the end facing away from the second section 320 is reduced, the end can be more easily inserted into the gap, allowing the entire first section 310 to be conveniently installed within the gap.

[0047] Furthermore, in some embodiments, the thickness of the first section 310 may gradually decrease in the direction away from the second section 320, that is, the first section 310 may be wedge-shaped, and when the end of the first section 310 away from the second section 320 is fitted into the gap, the first section 310 as a whole can be more conveniently fitted into the gap.

[0048] In some other embodiments, the first section 310 may have at least two regions with different thicknesses. The region of the first section 310 at the end away from the second section 320 has a smaller thickness to facilitate fitting the first section 310 into the gap.

[0049] In some other embodiments, the first section 310 and the second section 320 have the same thickness, and both are rigid structural members. It is readily understood that, because the first section 310 and the second section 320 have the same thickness, the second section 320 can fit within the gap between the first side bar 110 and the chair back 200. Furthermore, the second section 320 is a rigid structural member, and thus, the second section 320 can fit within the gap to restrict relative rotation between the seat panel 100 and the chair back 200.

[0050] The stopper 300 can be formed by bending a metal structure to have good rigidity. Furthermore, the stopper 300 can also include a plastic structure outside the metal structure, which can protect the stopper 300 on the one hand and the user on the other hand.

[0051] Furthermore, in some embodiments, the first section 310 and the second section 320 are both sheet-like structures. In other embodiments, only the first section 310 may be a sheet-like structure, and the second section 320 may be in a handle-like, hook-like, or other shape for easy handling.

[0052] In some embodiments, the first side bar 110 includes a rod-shaped structural member 111 and a shell-shaped structural member 112. The shell-shaped structural member 112 is a plastic structural member and surrounds the end of the rod-shaped structural member 111 facing the chair back 200. The extension direction of the first side bar 110 is the same as the extension direction of the rod-shaped structural member 111. In this embodiment, the rod-shaped structural member 111 can be made of a commercially available metal tubular structural member, such as a square metal tube or a round metal tube. This not only reduces the weight of the first side bar 110 but also reduces production costs. By providing the shell-shaped structural member 112 at the end of the rod-shaped structural member 111 facing the chair back 200, the sharp edge of the end of the rod-shaped structural member 111 can be covered, providing protection for the user and reducing the hard contact between the first side bar 110 and the stopper 300.

[0053] In some embodiments, the chair panel 100 further includes a second side bar 120, a cross bar 130, and a strip structure 140. The second side bar 120 is disposed parallel to the first side bar 110 and is pivotally connected to the chair back 200. The first side bar 110 and the second side bar 120 are both connected to the same side of the cross bar 130. The strip structure 140 is disposed parallel to the cross bar 130, with one end of the strip structure 140 connected to the first side bar 110 and the other end connected to the second side bar 120. The first side bar 110 and the second side bar 120 may have the same or different structures.

[0054] In some embodiments, the chair back 200 includes a back panel and a connector 210 disposed on the back panel. The connector 210 includes a first side panel 211 and a second side panel 212 that are opposed to each other. The first side bar 110 is located between the first side panel 211 and the second side panel 212. A rotating shaft 214 is connected between the first side panel 211 and the second side panel 212, and the rotating shaft 214 also passes through the first side bar 110. That is, the rotating shaft 214 is sequentially passed through the first side panel 211, the first side bar 110, and the second side panel 212. It is easy to understand that the first side panel 211 and the second side panel 212 are both connected to the first side bar 110 via the rotating shaft 214, allowing the first side bar 110 to rotate relative to the connector 210, thereby enabling relative rotation between the chair panel 100 and the chair back 200.

[0055] Since the first side panel 211 and the second side panel 212 are arranged on both sides of the first side rod 110 and are both connected to the first side rod 110 via the rotating shaft 214, the force on the first side rod 110 is more balanced, making it easier to rotate between the chair plate 100 and the chair back 200.

[0056] When the first side bar 110 includes a rod-shaped structure 111 and a shell-shaped structure 112, the rotating shaft 214 may pass only through the first rod-shaped structure 111, that is, the shell-shaped structure 112 is smaller in the extension direction of the rod-shaped structure 111. The rotating shaft 214 may also pass through both the rod-shaped structure 111 and the shell-shaped structure 112, that is, the shell-shaped structure is larger in the extension direction of the rod-shaped structure 111. Since the rotating shaft 214 also passes through the shell-shaped structure 112, it can prevent the shell-shaped structure 112 from falling off the rod-shaped structure 111.

[0057] Furthermore, a vertically penetrating area is formed between the first side plate 211 and the second side plate 212 , so that the end of the first side rod 110 can be rotated into or out of between the first side plate 211 and the second side plate 212 .

[0058] In some embodiments, the ends of the first side plate 211 and the second side plate 212 are directly connected to the back plate, and the gap is located between the back plate and the first side bar 110. In other embodiments, such as Figure 3 As shown, the connecting member 210 further includes a connecting plate 213. The connecting member 210 is an overall "U"-shaped structural member. The first side plate 211 and the second side plate 212 are respectively connected to both sides of the connecting plate 213, and the connecting plate 213 is connected to the chair back 200. The gap between the first side rod 110 and the connecting member 210 is located between the end of the first side rod 110 and the connecting plate 213 in the connecting member 210.

[0059] Furthermore, the folding chair further includes a support leg 400 fixedly connected to the chair board 100. The support leg 400 is used to contact the ground and thus play a role of a support structure. The fact that the support leg 400 is fixedly connected to the chair board 100 means that the connection position between the support leg 400 and the chair board 100 cannot perform relative movement, but can be disassembled, or may not be able to be disassembled. In some embodiments, the support leg 400 is connected to the lower side surface of the chair board 100. In some other embodiments, the support leg 400 may also be connected to both sides of the chair board 100. Further, the support leg 400 further includes a connecting rod and a roller assembly connected to each other. The connecting rod and the roller assembly can rotate relative to each other to enable relative rotation between the chair board 100 and the roller assembly; the connecting rod and the roller assembly can also be telescopic to adjust the height of the chair board 100.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
