Description

Technical Field

[0001] This application relates to the technical field of furniture, and particularly to an anti-tipping rocking chair frame and a rocking chair. Background Art

[0002] A rocking chair is a piece of furniture commonly used in homes, offices, or places for leisure and entertainment. Users can rock back and forth on the rocking chair to relax and enhance the comfort of use. Additionally, some rocking chairs on the market currently have an adjustable backrest angle, enabling the rocking chair to be adjusted to a sitting position or a lying position for the user to sit upright or lie down.

[0003] However, the backward rocking angle of rocking chairs on the market usually cannot be too large to prevent the rocking chair from tipping backward. For rocking chairs with sitting and lying positions, they can usually only rock in the sitting position, but not in the lying position. Because the center of gravity is further back in the lying position, the acceleration and inertia during rocking result in a large impact force when the rocking chair rocks backward, with an obvious sense of weightlessness and a high risk of tipping backward. Therefore, current rocking chairs usually have a mechanical structure to limit their rocking in the lying position. This makes the rocking angle of existing rocking chairs small and lacking the rocking function in the lying position, thus losing the comfortable experience of lying down and rocking.

[0004] In view of this, it is necessary to propose a new technical solution to overcome the above deficiencies. Summary of the Invention

[0005] This application provides an anti-tipping rocking chair frame and a rocking chair, which can reduce the risk of tipping during the swing of the rocking chair.

[0006] To achieve the above object, this application adopts the following technical solution: An anti-tipping rocking chair frame includes a base and a rocking frame that is supported on the base so as to be able to swing back and forth. The rocking frame is configured to be able to swing within a first angle range and a second angle range.

[0007] An anti-tipping device is engaged between the base and the rocking frame. The anti-tipping device includes an elastic coupling part and an elastic decoupling part.

[0008] Wherein, when the rocking frame swings within the second angle range, the elastic coupling part is configured to couple the rocking frame and the base into an elastic connection to apply an elastic force to the rocking frame to prevent the swing angle from increasing, thereby preventing the rocking frame from tipping over.

[0009] Wherein, when the rocking frame swings within the first angle range, the elastic decoupling part is configured to decouple the elastic connection between the rocking frame and the base to allow the rocking frame to swing freely.

[0010] In one embodiment, the rocking frame is capable of continuously swinging within a first angular range and a second angular range, and the elastic decoupling portion and the elastic coupling portion act on the rocking frame alternately.

[0011] In one embodiment, the rocking frame can be switched from a first angular range to a second angular range, wherein the rocking frame is in a sitting position within the first angular range and in a lying position within the second angular range.

[0012] In one embodiment, the anti-tipping rocking chair frame includes an electric push rod, and the electric push rod applies a force to the rocking frame to switch it between the first angular range and the second angular range.

[0013] In one embodiment, the anti-tipping device includes a tension spring, and the tension spring has an elastic helix, and the elastic helix constitutes the elastic coupling portion.

[0014] In one embodiment, the tension spring has a rigid sliding rod extending from at least one end of the elastic helix, and the rigid sliding rod constitutes the elastic decoupling portion.

[0015] In one embodiment, the tension spring is connected with a flexible rope, and the flexible rope constitutes the elastic decoupling portion. When the rocking frame swings within the first angular range, the flexible rope is in a relaxed state to decouple the elastic connection between the rocking frame and the base.

[0016] In one embodiment, connection holes are provided on the base and / or the rocking frame, and the rigid sliding rod passes through the connection holes and can slide along its own axis direction in the connection holes.

[0017] In one embodiment, an attachment is connected to the base and / or the rocking frame, and the connection hole is opened on the attachment, wherein the attachment can rotate relative to the base and / or the rocking frame to change the orientation of the connection hole to adapt to the sliding of the rigid sliding rod in its axis direction.

[0018] In one embodiment, the attachment is a connecting nail, and it is rotatably connected to the base.

[0019] The present application also adopts the following technical solution: A rocking chair, which includes a seat, a backrest and the anti-tipping rocking chair frame as described above, and the seat and the backrest are installed on the rocking frame.

[0020] In one embodiment, the backrest can rotate relative to the seat to switch between a sitting position and a lying position.

[0021] The anti-tipping rocking chair frame provided by the present application is equipped with an anti-tipping device. The anti-tipping device includes an elastic coupling part and an elastic decoupling part. When the rocking frame swings within the second angle range, under the action of the elastic coupling part, an elastic force that prevents the swing angle from increasing is applied to the rocking frame, thereby preventing the rocking frame from tipping over. When the rocking frame swings within the first angle range, due to the action of the elastic decoupling part, the rocking frame can swing freely; in this way, it not only does not affect the free swing of the rocking frame within the first angle range where there is no tipping risk, but also can reduce the tipping risk of the rocking frame through the elastic coupling part within the second angle range where there is a tipping risk, improving the comfort and safety of use.

[0035] The following will elaborate on some embodiments of this application in conjunction with the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0036] Please refer to Figures 1 to 5As shown, the present application discloses an anti-tipping rocking chair frame 100 and a rocking chair. The anti-tipping rocking chair frame 100 includes a base 1 and a rocking frame 2 that is supported on the base 1 so as to be swingable back and forth. The rocking frame 2 is configured to be able to swing within a first angular range and a second angular range. An anti-tipping device 3 is engaged between the base 1 and the rocking frame 2. The anti-tipping device 3 includes an elastic coupling portion 31 and an elastic decoupling portion 32. Among them, when the rocking frame 2 swings within the second angular range, the elastic coupling portion 31 is configured to couple the rocking frame 2 and the base 1 into an elastic connection to apply an elastic force to the rocking frame 2 to prevent the swing angle thereof from increasing, thereby preventing the rocking frame 2 from tipping over. When the rocking frame 2 swings within the first angular range, the elastic decoupling portion 32 is configured to decouple the elastic connection between the rocking frame 2 and the base 1 to allow the rocking frame 2 to swing freely.

[0037] The anti-tipping rocking chair frame 100 provided by the present application has an anti-tipping device 3, which neither affects the free swing of the rocking frame 2 within the first angular range without the risk of tipping over, nor can reduce the risk of tipping over of the rocking frame 2 by means of the elastic coupling portion 31 within the second angular range with the risk of tipping over, thus improving the use comfort and safety.

[0038] Please refer to Figure 1 and Figure 2 As shown, in an embodiment, the rocking frame 2 is further connected to a support base 6. The support base 6 is used to support on the ground where the rocking chair is placed. The support base 6 has a relatively large support area and can play a role in preventing tipping over. In this embodiment, the support base 6 includes a ring, a central seat located in the middle of the ring, and spokes connecting the central seat and the ring. The rocking frame 2 is connected to the central seat through the base 1. In this embodiment, the base 1 can rotate relative to the central seat on a horizontal plane so that the rocking chair can rotate on a horizontal plane relative to the support base 6 to achieve the swivel chair function.

[0039] The elastic coupling portion 31 refers to a component that can associate an elastic force between the base 1 and the rocking frame 2, and the elastic decoupling portion 32 refers to a component that releases the elastic force between the base 1 and the rocking frame 2. Please refer with emphasis to Figures 3 to 5 As shown, in this embodiment, the anti-tipping device 3 includes a tension spring. The tension spring has an elastic helix and a rigid sliding rod extending from at least one end of the elastic helix. The elastic helix constitutes the elastic coupling portion 31, and the rigid sliding rod constitutes the elastic decoupling portion 32.

[0040] Specifically, both ends of the tension spring are provided with hook portions 33 respectively used for hooking on the base 1 and the rocker 2. When the rocker 2 swings within the first angle range, the hook portion 33 connected to the rigid link does not contact the base 1 or the rocker 2. When the rocker 2 and the base 1 move relative to each other, the relative position or angle between the two changes. At this time, the rigid slide rod of the tension spring can slide freely on the rocker 2 or the base 1, and the elastic spiral body of the tension spring is not stretched. That is, during this movement process, the rocker 2 is in a free swing state. As Figure 3 and Figure 4 shown, it is a diagram of the rocker 2 swinging within the first angle range. As the movement position or angle of the rocker 2 relative to the base 1 increases, when the hook portions 33 at both ends of the tension spring contact the base 1 and the rocker 2 respectively, it reaches the critical point of the free swing state, as Figure 3 shown; at this time, if the movement position or angle of the rocker 2 relative to the base 1 further increases, the elastic spiral body of the tension spring is stretched, reaching the state as Figure 5 shown, realizing the application of an elastic force to prevent the swing angle of the rocker 2 from increasing, thereby preventing the rocker 2 from tipping over.

[0041] It should be noted that in this embodiment, the anti-tipping device 3 includes a tension spring; in other embodiments, the anti-tipping device can also adopt elastic ropes such as rubber bands, and other elastic components. In this embodiment, a rigid slide rod is provided at one end of the tension spring, and no rigid slide rod is provided at the other end, and it is directly hooked on the base 1 or the rocker 2 through the hook portion 33; in other embodiments, rigid slide rods can be provided at both ends of the tension spring. In this embodiment, the rigid slide rod is connected to the base 1; in other embodiments, the rigid slide rod can also be connected to the rocker 2. In this embodiment, decoupling is achieved by the sliding of the base 1 on the rigid slide rod; in other embodiments, the tension spring may not adopt a rigid link, but is connected with a flexible rope, and the flexible rope constitutes the elastic decoupling portion 32. When the rocker 2 swings within the first angle range, the flexible rope is in a relaxed state to decouple the elastic connection between the rocker 2 and the base 1.

[0042] Please continue to refer to Figure 3As shown, in this embodiment, the base 1 is provided with a connecting hole 41, and the rigid slide bar is inserted into the connecting hole 41 and can slide in the connecting hole 41 along its own axis direction. During the swinging process of the cradle 2, the change in the angle between the cradle 2 and the base 1 will drive the axis direction of the tension spring to change. If the direction of the connecting hole 41 remains unchanged, the rigid slide bar will not slide smoothly therein, or even get stuck. Therefore, the present application further sets the direction of the connecting hole 41 to be movable. Specifically, the base 1 is connected with an attachment 4, and the connecting hole 41 is opened on the attachment 4, wherein the attachment 4 can rotate relative to the base 1 to change the direction of the connecting hole 41 and adapt to the sliding of the rigid slide bar in its axis direction. In this embodiment, the attachment 4 is a connecting nail, which is rotatably connected to the base 1. In other embodiments, the attachment 4 can also be connected to the base 1 in the form of a universal head. This embodiment is described by taking the example that the connection hole 41 is connected to the base 1 through the attachment 4 . It can be understood that in other embodiments, the connection hole 41 can also be connected to the cradle 2 through the attachment 4 .

[0043] See also Figure 6 As shown, in one embodiment, the cradle 2 can swing continuously within a first angle range and a second angle range, and the elastic decoupling portion 32 and the elastic coupling portion 31 act on the cradle 2 alternately. That is, during the continuous swinging process, when the cradle 2 tilts back at a small angle, the elastic decoupling portion 32 acts on the cradle 2, as described in the above embodiments, when the cradle 2 slides back on the rigid slide bar or the flexible rope is in a relaxed state, and the cradle 2 swings freely; during the continuous swinging process, when the cradle 2 tilts back at a large angle, the elastic coupling portion 31 acts on the cradle 2, as described in the above embodiments, when the rigid slide bar slides to the end or the flexible rope is pulled to a tensioned state, the elastic spiral is stretched to reduce the inertial impact force of the cradle 2 swinging back and prevent it from tipping over. Figure 6 As shown in , the cradle 2 can be continuously rocked between the positions shown by the line c1 and the line c2 . During the rocking process of the cradle 2 , the elastic decoupling portion 32 and the elastic coupling portion 31 act on the cradle 2 alternately.

[0044] See also Figure 7 As shown, in another embodiment, the cradle 2 can be switched from a first angle range to a second angle range, wherein the cradle 2 is in a sitting position within the first angle range and in a lying position within the second angle range. Figure 7As shown by line a, the rocking frame 2 is in a sitting position. At this time, the rocking frame 2 can swing between line a1 and line a2, that is, the first angle range is formed between line a1 and line a2. Since the backward tilt angle of the rocking frame 2 is small in the sitting position and the possibility of tipping over is small, in order to avoid resistance during swinging, the elastic decoupling part 32 acts, and the elastic coupling part 31 does not provide elastic force, and the rocking frame 2 swings freely. When the user operates and adjusts the rocking frame 2 to a lying position through electric or manual drive, as Figure 7 shown by line b, at this time, the rocking frame 2 can swing between line b1 and line b2, that is, the second angle range is formed between line b1 and line b2. Since the backward tilt angle of the rocking frame 2 is large in the lying position and the possibility of tipping over is large, in order to prevent the rocking frame 2 from tipping backward, the elastic coupling part 31 acts to provide an elastic pulling force forward for the rocking frame 2 to prevent the rocking frame 2 from tipping backward. Please refer to again Figure 1 and Figure 2 shown, in this embodiment, the anti-tipping rocking chair frame 100 includes an electric push rod (not shown), the electric push rod is installed on the mounting seat 5, and the electric push rod applies force to the rocking frame 2 to switch it between the first angle range and the second angle range, so as to realize the switching between the sitting position and the lying position.

[0045] This application also provides a rocking chair, which includes a seat, a backrest and the anti-tipping rocking chair frame 100 as described above, and the seat and the backrest are installed on the rocking frame 2. The backrest can rotate relative to the seat to switch between the sitting position and the lying position. In one embodiment of the rocking chair provided by this application, the rocking function in the lying position can be realized, and a comfortable experience of lying down and rocking can be obtained.

[0046] From the description of the specific embodiments above, it can be seen that the anti-tipping rocking chair frame 100 provided by this application includes a base 1 and a rocking frame 2. The rocking frame 2 can swing within the first angle range and the second angle range. The anti-tipping rocking chair frame 100 has an anti-tipping device 3. The anti-tipping device 3 includes an elastic coupling part 31 and an elastic decoupling part 32. When the rocking frame 2 swings within the second angle range, under the action of the elastic coupling part 31, the rocking frame 2 is applied with an elastic force to prevent the increase of its swing angle, thereby preventing the rocking frame 2 from tipping over. When the rocking frame 2 swings within the first angle range, due to the action of the elastic decoupling part 32, the rocking frame 2 can swing freely. In this way, it not only does not affect the free swing of the rocking frame 2 within the first angle range without the risk of tipping over, but also can reduce the risk of tipping over of the rocking frame 2 by means of the elastic coupling part 31 within the second angle range with the risk of tipping over, improving the use comfort and safety.

[0047] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
