Description

Technical Field

[0001] This utility model relates to the technical field of chairs, and more particularly to a rocking chair and its frame. Background Technology

[0002] With the continuous development of the economy and the continuous progress of society, people are provided with an extremely rich variety of material consumer goods, and rocking chairs are one of these many material consumer goods.

[0003] Among them, the elastic support leg and its folding chair frame disclosed in Chinese Patent Application No. 202321856048.3 have a noticeable jerking sensation and poor shock absorption effect because the elastic support leg includes a base rod, a support rod, and an elastic element forming a triangular configuration. Furthermore, since the elastic element is directly installed to the base rod, when used outdoors, harmful substances such as mud and dew can easily enter the elastic element, causing it to rust, reducing the shock absorption effect, increasing abnormal noise, and even damaging the elastic element.

[0004] Therefore, there is an urgent need for a rocking chair and its frame to overcome one or more of the aforementioned defects. Utility Model Content

[0005] One objective of this invention is to provide a front-to-back rocking chair frame that offers a smoother shock absorption effect, less jerking sensation, and greater comfort.

[0006] Another objective of this invention is to provide a rocking chair with a smoother shock absorption effect, less jerking sensation, and better comfort.

[0007] To achieve the above objectives, the present invention provides a rocking chair frame that includes a frame and a rocking mechanism for rocking the frame back and forth. The rocking mechanism includes a connecting rod, a pivot connecting frame, a shock absorber, and an elastic base plate. The elastic base plate is located below the frame and extends along the front-rear direction of the frame. The front end of the elastic base plate is fixedly connected to the frame. The pivoting connecting frame is located above the elastic base plate. The pivoting connecting frame is provided with a first hinge structure for hinged connection with the frame, a second hinge structure located above and in front of the first hinge structure, and a third hinge structure located above and behind the first hinge structure. The shock absorber is located in front of the second hinge structure. The shock absorber has a shock absorber body and a sliding telescopic body that slides and extends within the shock absorber body along the front-rear direction of the frame. One of the sliding telescopic body and the shock absorber body is hinged to the frame, and the other of the sliding telescopic body and the shock absorber body is assembled and connected to the second hinge structure. The connecting rod is arranged at an angle of rear-lower and front-up along the vertical direction of the frame. The rear end of the connecting rod is hinged to the rear end of the elastic base plate, and the front end of the connecting rod is assembled and connected to the third hinge structure.

[0008] Compared to existing technologies, this new type of rocking chair frame is supported on external supports such as the ground by a swing mechanism. Since the swing mechanism contacts the ground through an elastic base plate, during the backward swing of the frame, the elastic base plate first undergoes slight elastic deformation, which is then transmitted to the connecting rod. The connecting rod drives the pivot connecting frame, causing the sliding telescopic body to retract into the shock absorber body. This gives the front and rear swinging chair frame of this invention a dual shock absorption function, resulting in a smoother, less jerky, and more comfortable shock absorption effect. Furthermore, because the shock absorber is not assembled and connected to the ground-hugging elastic base plate, but rather to the frame located above the elastic base plate, it lifts the shock absorber off the ground. This prevents harmful substances such as dirt and dew from entering the shock absorber, causing it to rust and reduce its shock absorption effect, or even damage it, thus protecting the shock absorber.

[0009] Preferably, the rear end of the elastic base plate is bent upward and tilted relative to the front end of the elastic base plate; the pivot connecting frame has a hollow cavity, and the first hinge structure, the second hinge structure and the third hinge structure are arranged together around the hollow cavity.

[0016] Preferably, the shock absorber is a gas spring.

[0017] Preferably, the elastic base plate is a spring plate.

[0018] Preferably, the frame is a folding frame that can be unfolded or folded in the left and right directions, and the swing mechanism is provided on both the left and right sides of the frame.

[0019] Preferably, the frame includes a left side frame, a right side frame, a first crossbeam, and a second crossbeam. The left side frame and the right side frame are arranged side-by-side, spaced apart from each other. The first crossbeam is arranged at an angle from left to right, with its left end hinged to the lower end of the left side frame and its right end extending to a position adjacent to the right side frame. The second crossbeam is arranged at an angle from right to left, with its right end hinged to the lower end of the right side frame and its left end extending to a position adjacent to the left side frame. The middle portions of the second crossbeam and the first crossbeam are also hinged to each other to form a middle hinge point. In the left-side swing mechanism, the front end of the elastic base plate is fixedly connected to the lower end of the left side frame. Next, the pivot connecting frame is hinged to the left frame at an upper position away from the lower end of the left frame via the first hinge structure. The left frame is also provided with a left handrail at an upper position away from the lower end of the left frame, and the left handrail is provided with a left hinge structure for the sliding telescopic body or shock absorber body to hinge. In the right swing mechanism, the front end of the elastic base plate is fixedly connected to the lower end of the right frame. The pivot connecting frame is hinged to the right frame at an upper position away from the lower end of the right frame via the first hinge structure. The right frame is also provided with a right handrail at an upper position away from the lower end of the right frame, and the right handrail is provided with a right hinge structure for the sliding telescopic body or shock absorber body to hinge.

[0025] To achieve the above objectives, the present invention provides a front-to-back rocking chair including a seat and the aforementioned front-to-back rocking chair frame, wherein the seat is mounted on the frame and located above the rocking mechanism.

[0026] Compared to existing technologies, this new type of rocking chair features a frame supported by a swing mechanism on an external support such as the ground. The swing mechanism, with its contact with the ground via an elastic base plate, causes a slight elastic deformation of the base plate during the backward swing. This deformation is then transmitted to the connecting rod, which in turn drives the pivoting frame to retract the sliding telescopic body into the shock absorber body. This results in dual shock absorption, providing a smoother, less jerky, and more comfortable experience. Furthermore, because the shock absorber is not attached to the ground-level elastic base plate but rather to the frame located above it, it lifts the shock absorber off the ground. This prevents harmful substances such as dirt and dew from entering the shock absorber, which could cause rust, reduce its effectiveness, or even damage it, thus protecting the shock absorber.

[0033] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0034] Please combine Figure 1 and Figure 2 The present invention relates to a front-to-back rocking chair 1000, comprising a front-to-back rocking chair frame 100 and a seat 200. The seat 200 is mounted on the frame 10 described below of the rocking chair frame 100, and the frame 10 provides support for the seat 200. The seat 200 is also located above the rocking mechanism 20 described below of the front-to-back rocking chair frame 100. Optionally, in... Figure 1 In this example, the seat 200 is a sheet-like fabric structure to accommodate the need for the seat 200 to fold or unfold together with the rocking chair frame 100. Obviously, depending on actual needs, the seat 200 can also be other structures known in the art, therefore, it is not considered... Figure 1 The above is the limit.

[0035] Combined Figures 3 to 5 The rocking chair frame 100 includes a frame 10 and a rocking mechanism 20 for rocking the frame 10 back and forth; optionally, in Figures 1 to 5 In this example, the frame 10 is a folding frame that can be unfolded or folded in the left and right directions. This design facilitates the storage and transportation of the front-to-back rocking chair 1000 when not in use, and minimizes the space occupied by the chair when folded. Obviously, depending on actual needs, the frame 10 can also be designed to be non-foldable, therefore it is not considered... Figures 1 to 5 The above description is for illustrative purposes only. It should be noted that when the frame 10 is a folding frame that can be unfolded or folded in the left and right directions, a swing mechanism 20 is provided on both the left and right sides of the frame 10. This better meets the need for the swing mechanism 20 to follow the frame 10 in its left and right unfolding and folding operations, and provides better shock absorption during the back-and-forth swinging of the frame 10, thereby improving user comfort. When the frame 10 is designed to be non-foldable, the swing mechanism 20 can be provided on both the left and right sides of the frame 10, or on the left, middle, or right side of the frame 10. Therefore, it is not limited to the swing mechanism 20. Figures 1 to 5 The above is the limit.

[0036] Meanwhile, the swing mechanism 20 includes a connecting rod 21, a pivot connecting frame 22, a shock absorber 23, and an elastic base plate 24. The elastic base plate 24 is located below the frame 10 to meet the need for the frame 10 to contact the ground with the help of the elastic base plate 24 below it, thereby achieving the purpose of lifting the frame 10 off the ground; in addition, the elastic base plate 24 also extends along the front and rear direction of the frame 10 so that the elastic base plate 24 is elongated. The front end 241 of the elastic base plate 24 is fixedly connected to the frame 10, for example, by welding or using fasteners, so as to better meet the need for the rear end 242 of the elastic base plate 24 to elastically deform relative to the frame 10.

[0037] Furthermore, the pivoting connecting frame 22 is located above the elastic base plate 24. The pivoting connecting frame 22 is provided with a first hinge structure 221 for hinged connection with the frame 10, a second hinge structure 222 located above and in front of the first hinge structure 221, and a third hinge structure 223 located above and behind the first hinge structure 221. This satisfies the requirement that the first hinge structure 221, the second hinge structure 222, and the third hinge structure 223 are arranged in a triangular configuration, thereby effectively improving the amplitude and reliability of the frame 10's forward and backward swaying. The connecting rod 21 is arranged at an angle from rear-down to front-up along the vertical direction of the frame 10. The rear end 211 of the connecting rod 21 is hinged to the rear end 242 of the elastic base plate 24 to satisfy the requirement that the connecting rod 21 can pivot relative to the elastic base plate 24. The front end 212 of the connecting rod 21 is assembled and connected to the third hinge structure 223 to satisfy the requirement that the front end 212 of the connecting rod 21 is hinged to the pivoting connecting frame 22 via the third hinge structure 223.

[0038] The shock absorber 23 is located in front of the second hinge structure 222. The shock absorber 23 has a shock absorber body 231 and a sliding telescopic body 232 that slides and extends within the shock absorber body 231 along the front-rear direction of the frame 10. The sliding telescopic body 232 is assembled and connected to the second hinge structure 222 to meet the need for the sliding telescopic body 232 to be hinged to the pivot connecting frame 22 via the second hinge structure 222. The shock absorber body 231 is hinged to the frame 10. This design allows the shock absorber 23 and the pivot connecting frame to... The shock absorber body 231 and the frame 10 together constitute a crank-rocker mechanism. Therefore, in the crank-rocker mechanism, the shock absorber body 231 forms the rocker block, the pivot connecting frame 22 forms the crank, the frame 10 forms the frame, and the sliding telescopic body 232 forms the connecting rod. Obviously, according to actual needs, the shock absorber body 231 can also be assembled and connected to the second hinge structure 222, and the sliding telescopic body 232 can be hinged to the frame 10. Therefore, it is not necessary to... Figures 1 to 5 The description is for illustrative purposes only. Specifically, the shock absorber 23 is a gas spring. Obviously, depending on actual needs, the shock absorber 23 can also be other shock absorbers well known in the art, therefore it is not limited to these examples. Figures 1 to 5The design shown is for illustrative purposes only; furthermore, the elastic base plate 24 is a spring plate. Obviously, depending on actual needs, the elastic base plate 24 can also be other elastic structures, therefore it is not limited to the one shown. Figures 1 to 5 The above is for reference only. For more details, see the description below.

[0039] like Figure 3 and Figure 4 As shown, as an example, the rear end 242 of the elastic base plate 24 bends upward and tilts up relative to the front end 241 of the elastic base plate 24. This makes it easier for the frame 10 to swing back and forth, and also makes the elastic deformation of the elastic base plate 24 smaller during the swinging of the frame 10.

[0040] like Figures 1 to 4 and Figure 6 As shown, as an example, the pivoting connecting frame 22 has a hollow cavity 224. The first hinge structure 221, the second hinge structure 222, and the third hinge structure 223 are arranged around the hollow cavity 224, so that the pivoting connecting frame 22 can effectively reduce its weight and material usage while maintaining sufficient strength. Specifically, in Figures 1 to 4 and Figure 6 In this example, the pivot connector 22 is triangular in shape to effectively improve its stability by taking advantage of the fact that triangles are not easily deformed. When the pivot connector 22 is triangular, the first hinge structure 221, the second hinge structure 222, and the third hinge structure 223 are located at the corners of the pivot connector 22. In addition, the hollow cavity 224 is triangular so that the pivot connector 22 forms a triangular ring structure with uniform size in all parts, thereby ensuring the uniformity of strength in all parts of the pivot connector 22.

[0041] In order to allow the frame 10 to pass through the pivot connecting frame 22, in Figures 1 to 6 As an example, the pivoting connecting frame 22 includes a first support 22a and a second support 22b arranged side-by-side in the left-right direction of the frame body 10. The frame body 10 is located between the first support 22a and the second support 22b, as shown in the diagram. Figure 1 and Figure 2 As shown; at this time, the first hinge structure 221 is simultaneously inserted into the frame 10, the first support 22a, and the second support 22b along the left-right direction of the frame 10. The second hinge structure 222 and the third hinge structure 223 are each inserted into the first support 22a and the second support 22b along the left-right direction of the frame 10. The first hinge structure 221, the second hinge structure 222, and the third hinge structure 223 together fix the first support 22a and the second support 22b together. This design can also control the forward and backward sway range of the frame 10, specifically, the forward and backward sway of the frame 10 is constrained by the front second hinge structure 222 and the rear third hinge structure 223. Furthermore, Figure 2 In this example, to improve the reliability of the connection, the front end 212 of the connecting rod 21 and the sliding telescopic body 232 are respectively located between the first bracket 22a and the second bracket 22b. Specifically, in Figure 6 In this example, the first support 22a and the second support 22b are each a matching triangular plate, preferably of the same size, thus reducing the size of the plates. In this case, the first hinge structure 221 is inserted into one corner of both the first support 22a and the second support 22b, the second hinge structure 222 is inserted into another corner of both the first support 22a and the second support 22b, and the third hinge structure 223 is inserted into yet another corner of both the first support 22a and the second support 22b. It is understandable that when the pivoting connecting frame 22 includes the first support 22a and the second support 22b, the triangular cavities 224 formed by the pivoting connecting frame 22 are located on the first support 22a and the second support 22b respectively; that is, each of the first support 22a and the second support 22b has a cavity 224.

[0042] like Figures 1 to 5 As shown, as an example, the frame 10 includes a left frame 11, a right frame 12, a first crossbeam 13, and a second crossbeam 14. The left frame 11 and the right frame 12 are arranged side-by-side, spaced apart from each other; alternatively, in... Figure 3 In this example, the lower end 111 of the left frame 11 and the upper position 112 of the left frame 11 away from the lower end 111 are arranged at an obtuse angle to make the structure of the left frame 11 simpler and facilitate the back-and-forth swinging operation of the left frame 11; Figure 4 In this example, the lower end 121 of the right frame 12 and the upper position 122 of the right frame 12 away from the lower end 121 are arranged at an obtuse angle to make the structure of the right frame 12 simpler and facilitate the back-and-forth swinging operation of the right frame 12. Obviously, depending on actual needs, the shape of the left frame 11 can also be other shapes well known in the art, so it is not considered... Figure 3 The shape shown is limited; similarly, depending on actual needs, the shape of the right-side skeleton 12 can also be other shapes well known in the art, therefore it is not limited to those shown. Figure 4 The above is the limit.

[0043] At the same time, Figure 5In the example shown, the first crossbeam 13 is arranged at an angle from lower left to upper right. The left end 131 of the first crossbeam 13 is hinged to the lower end 111 of the left side frame 11, and the right end 132 of the first crossbeam 13 extends to a position adjacent to the right side frame 12. The second crossbeam 14 is arranged at an angle from lower right to upper left. The right end 141 of the second crossbeam 14 is hinged to the lower end 121 of the right side frame 12, and the left end 142 of the second crossbeam 14 extends to a position adjacent to the left side frame 11. The middle portions of the second crossbeam 14 and the first crossbeam 13 are also hinged to each other to form a middle hinge point 15, so that the second crossbeam 14 and the first crossbeam 13 are arranged in an "X" shape, as shown in the diagram. Figure 5 As shown.

[0044] At this time, in the left swing mechanism 20, the front end 241 of the elastic base plate 24 is fixedly connected to the lower end 111 of the left frame 11. The pivot connecting frame 22 is hinged to the left frame 11 at the upper position 112 away from the lower end 111 of the left frame 11 by means of the first hinge structure 221. The left frame 11 is also provided with a left handrail 113 at the upper position 112 away from the lower end 111 of the left frame 11. The left handrail 113 is provided with a left hinge structure 114 for the shock absorber body 231 to be hinged.

[0045] Meanwhile, in the right-side swing mechanism 20, the front end 241 of the elastic base plate 24 is fixedly connected to the lower end 121 of the right-side frame 12. The pivot connecting frame 22 is hinged to the right-side frame 12 at the upper position 122 away from the lower end 121 of the right-side frame 12 by means of the first hinge structure 221. The right-side frame 12 is also provided at the upper position 122 away from the lower end 121 of the right-side frame 12. The right-side handrail 123 is provided on the right handrail 123 for the shock absorber body 231 to be hinged. Therefore, by using the frame 10, which includes a left frame 11, a right frame 12, a first crossbeam 13, and a second crossbeam 14, the frame 10 simplifies the structure while allowing for expansion and contraction in the left and right directions, and also improves the convenience of the expansion and contraction operation. In addition, by using the left handrail 113 and the right handrail 123, the shock absorber bodies 231 on the left and right sides are provided with hinge positions, and the shock absorbers 23 on the left and right sides are further lifted off the ground, thus providing better protection for the shock absorbers 23 on the left and right sides.

[0046] Combination Figures 1 to 5As an example, the first crossbeam 13 is provided with a right-side mounting rod 133 adjacent to the right armrest 123 and for mounting on the right side 210 of the seat portion 200, and a first rod 134 located below the right-side mounting rod 133. The first rod 134 is rotatably connected to the upper position 122 of the first crossbeam 13 and the right frame 12, respectively. The second crossbeam 14 is provided with a left-side mounting rod 143 adjacent to the left armrest 113 and for mounting on the left side 220 of the seat portion 200, and a second rod 144 located below the left-side mounting rod 143. The second rod 144 is rotatably connected to the upper position 112 of the second crossbeam 14 and the left frame 11, respectively; see the state. Figure 5 As shown. Therefore, by means of the mounting rod 133 on the right side of the seat, the mounting rod 143 on the left side of the seat, the first rod 134, and the second rod 144, the reliability of the seat 200 being supported by the frame 10 is further improved, and the folding operation of the frame 10 is made easier. Specifically, in Figure 5 In the example, the rotatable connection 16 between the first rod 134 and the first crossbeam 13 is located between the right end 132 and the middle hinge 15 of the first crossbeam 13; the rotatable connection 15 between the second rod 144 and the second crossbeam 14 is located between the left end 142 and the middle hinge 15 of the second crossbeam 14. Obviously, depending on actual needs, the rotatable connection 16 between the first rod 134 and the first crossbeam 13 can also be located at other positions on the first crossbeam 13, and the rotatable connection 17 between the second rod 144 and the second crossbeam 13 can also be located at other positions on the second crossbeam 14. Therefore, it is not considered... Figure 5 The above is the limit.

[0047] Compared with the prior art, since the frame 10 is supported on the ground or other external support by means of the swing mechanism 20, and the swing mechanism 10 contacts the ground through the elastic base plate 24, during the backward swing of the frame 10, for example... Figure 3 During the clockwise swaying of the frame 10, the elastic base plate 24 first undergoes slight elastic deformation, which is then transmitted to the connecting rod 21. The connecting rod 21 then drives the pivoting connecting frame 22 to pivot relative to the frame 10. For example, by Figure 3 The connecting rod 21 drives the pivoting connecting frame 22 to pivot counterclockwise relative to the frame 10, causing the sliding telescopic body 232 to slide into the shock absorber body 231. This gives the front and rear rocking chair 1000 of this invention a dual shock absorption function, resulting in a smoother, less jerky shock absorption effect and better comfort. Furthermore, since the shock absorber 23 is not assembled and connected to the ground-level elastic base plate, but rather to the frame 10 located above the elastic base plate 24, it lifts the shock absorber 23 off the ground. This prevents harmful substances such as dirt and dew from entering the shock absorber 23, which could cause it to rust, reduce its shock absorption effect, or even damage it, thus protecting the shock absorber 23.

[0048] It is worth noting that in the attached diagram, arrow A points in the direction from front to back of frame 10, arrow B points in the direction from top to bottom of frame 10, and arrow C points in the direction from left to right of frame 10. Additionally, regarding... Figures 1 to 5 As an example, the rear end 242 of the elastic base plate 24 is provided with a rear hinge structure 243 for hinged to the rear end 211 of the connecting rod 21. Furthermore, in... Figure 1 In the case where the left frame 11 is provided with a left handrail 113 and the right frame 12 is provided with a right handrail 123, the seat 200 is also assembled at the positions of the left handrail 113, the right handrail 123, the left frame 11 above the left handrail 113, and the right frame 12 above the right handrail 123. Finally, when the pivot connecting frame 22 includes a first support 22a and a second support 22b, and the frame 10 includes a left frame 11, a right frame 12, a first crossbeam 13, and a second crossbeam 14, the upper position 112 of the left frame 11 away from its lower end 111 is located between the first support 22a and the second support 22b, and the upper position 122 of the right frame 12 away from its lower end 121 is located between the first support 22a and the second support 22b.

[0049] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
