Description

Technical Field

[0001] This application relates to the field of table technology, and in particular to a table frame and a table having the table frame. Background Technology

[0002] As living standards improve, outdoor activities are becoming increasingly popular. Activities such as camping, outdoor barbecues, and group meals are highly sought after. These outdoor activities often require the use of tables and chairs to set out food or play board games.

[0003] Tables used in outdoor settings such as camping often employ foldable frames for portability. For example, CN219330946U discloses a novel portable camping table whose frame includes multiple movable linkages, allowing the frame to be folded individually as per its instruction manual. Figure 4 The shape shown makes it easy to carry.

[0004] However, the camping table disclosed in this patent, like most camping tables on the market, only takes into account the ease of carrying after folding. The design goal is to make the folded table frame more compact for easy carrying, with insufficient consideration for the convenience of folding. Utility Model Content

[0005] This application provides a table frame and a table having the table frame, the table frame being foldable with one hand.

[0006] To achieve the above objectives, this application first provides a table frame, which includes a first rod group, a second rod group, a third rod group, and a fourth rod group for supporting the tabletop on an external plane, as well as a folding assembly and a linkage rod group, wherein:

[0007] Each rod group includes two rods rotatably connected at one end. The first rod group and the second rod group are rotatably connected at the rotatably connected end of the rods to form a first support frame. The third rod group and the fourth rod group are rotatably connected at the rotatably connected end of the rods to form a second support frame.

[0008] The linkage group is disposed between the first support frame and the second support frame, and has an unfolded state and a folded state. In the unfolded state, the linkage group can spread the first support frame and the second support frame apart by a preset distance. In the folded state, the linkage group can make the first support frame and the second support frame relatively close together.

[0009] The folding assembly includes a flexible main body, four folding drive rods, and four drive sliders rotatably connected to one end of each of the four folding drive rods. The other end of each of the four folding drive rods is rotatably connected to one rod in each rod group. The drive sliders are slidably connected to another rod in each rod group. The four drive sliders are fixed relative to the main body. The linkage rod group is connected to the drive sliders to switch from the unfolded state to the folded state as the drive sliders slide.

[0010] Furthermore, the table frame includes two sets of linkage rods spaced apart, wherein: a set of linkage rods is provided between the first rod set and the third rod set; and a set of linkage rods is provided between the second rod set and the fourth rod set.

[0011] Furthermore, the first rod group includes a first rod and a second rod that are rotatably connected; the second rod group includes a third rod and a fourth rod that are rotatably connected; the third rod group includes a fifth rod and a sixth rod that are rotatably connected; and the fourth rod group includes a seventh rod and an eighth rod that are rotatably connected. The first rod, the third rod, the fifth rod, and the seventh rod together support the tabletop; the lower ends of the second rod, the fourth rod, the sixth rod, and the eighth rod together support the external plane.

[0012] Further, the linkage group includes a first linkage rod and a second linkage rod that are cross-connected and rotatably connected at the intersection, wherein: in the linkage group disposed between the first linkage group and the third linkage group, the upper end of the first linkage rod is rotatably connected to the driving slider slidably connected to the second rod, the lower end of the first linkage rod is rotatably connected to the sixth rod, the upper end of the second linkage rod is rotatably connected to the driving slider slidably connected to the sixth rod, and the lower end of the second linkage rod is rotatably connected to the second rod; in the linkage group disposed between the second linkage group and the fourth linkage group, the upper end of the first linkage rod is rotatably connected to the driving slider slidably connected to the eighth rod, the lower end of the first linkage rod is rotatably connected to the fourth rod, the upper end of the second linkage rod is rotatably connected to the driving slider slidably connected to the fourth rod, and the lower end of the second linkage rod is rotatably connected to the eighth rod.

[0013] Furthermore, the table frame also includes two sets of auxiliary support rods respectively connected between the first rod and the fifth rod, and between the third rod and the seventh rod. Each auxiliary support rod set includes a first support rod and a second support rod rotatably connected at one end, wherein: in one set of auxiliary support rods, the other ends of the first support rod and the second support rod are rotatably connected to the first rod and the fifth rod, respectively; in the other set of auxiliary support rods, the other ends of the first support rod and the second support rod are rotatably connected to the third rod and the seventh rod, respectively.

[0014] Furthermore, a pivot connector is provided on the first rod, the third rod, the fifth rod, and the seventh rod, and the first support rod, the second support rod, and the four stacking drive rods are all rotatably connected to the pivot connector.

[0015] Furthermore, each of the rods used to slidably connect the drive slider is provided with a groove for guiding the drive slider to slide along the length direction of the corresponding rod.

[0016] Furthermore, the folding assembly also includes a lifting portion fixed to the upper side of the main body, the lifting portion being used to lift the main body upward to drive the four driving sliders to slide.

[0017] Furthermore, the main body is configured as a flexible cloth block, and flexible connecting rings are fixed at the four corners of the cloth block. The four driving sliders are respectively connected to the main body through the four connecting rings. When the table frame is in a folded state, the main body can surround all the rods and fix the table frame in the folded state through a fixed connector.

[0018] A second aspect of this application also provides a table comprising a table frame as described in any of the above claims, and a tabletop, the tabletop being configured as a rollable and foldable flexible tabletop.

[0019] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0020] When folding the table frame, the user pulls the main body of the folding assembly in one direction, causing four drive sliders fixed relative to the main body to slide on four rods. The sliding of the four drive sliders then drives the four folding drive rods to move, causing the two rods in each rod group to rotate relative to each other and come closer together. At the same time, the sliding of the drive sliders also causes the linkage rod group to switch to the folding state, thus bringing the two support frames closer together. In this state, when the main body is pulled further, the first and third rod groups come closer together under the action of gravity, and the second and fourth rod groups come closer together under the action of gravity, thus causing the eight rods in the four rod groups to fold together, completing the folding of the table frame. During this folding process, the user only needs to pull the main body to complete the folding of the table frame, which can be done by one person or even one hand. Moreover, the folded table frame is also small in size and easy to carry.

[0021] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The modes described in the following exemplary embodiments do not represent all modes consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0034] like Figure 1 and Figure 2 As shown in the illustration, an embodiment of this application first provides a table, which includes a table frame 100 and a tabletop 200, wherein the table frame 100 supports the tabletop 200 on an external plane. In the illustrated embodiment, the tabletop 200 is configured as a flexible, rollable, and foldable tabletop, thus forming a table that can be used as a common egg roll table in camping settings.

[0035] It is understood that in other embodiments, the tabletop 200 may also adopt other forms of foldable or non-foldable plate-like support structure, as long as it can meet the requirement of forming a tabletop that can be used to place items on the table frame 100 or above.

[0036] like Figure 4 As shown in the illustration, an embodiment of this application also provides a table frame 100, which can be used as... Figures 1 to 3 The table frame 100 includes four sets of structurally similar rods: a first rod set 11, a second rod set 12, a third rod set 13, and a fourth rod set 14. The table frame 100 also includes a folding assembly 15 and a linkage rod set 16.

[0037] Each linkage group includes two rods rotatably connected at one end. The first linkage group 11 and the second linkage group 12 are rotatably connected at the ends where the rods are rotatably connected to form a first support frame. Similarly, the third linkage group 13 and the fourth linkage group 14 are also rotatably connected at the ends where the rods are rotatably connected to form a second support frame. (Combined...) Figure 3 In the embodiment shown, along the width direction of the tabletop 200 in the figure, the first support frame and the second support frame are spaced apart from each other on the left and right and jointly support the tabletop 200.

[0038] The linkage assembly 16 is disposed between the first support frame and the second support frame, and the linkage assembly 16 itself has an extended state and a folded state. Figure 4 Based on the combination Figure 3 As shown, when the linkage group 16 is in the unfolded state, the linkage group 16 is used to maintain the interval between the first support frame and the second support frame, thereby stably supporting the table 200; in the folded state, the linkage group 16 enables the first support frame and the second support frame to move closer together.

[0039] like Figure 4 As shown, the folding assembly 15 includes a flexible main body 151, four folding drive rods 154, and four drive sliders 153 rotatably connected to one end of each of the four folding drive rods 154. The other end of each of the four folding drive rods 154 is rotatably connected to one rod in each rod group. The drive sliders 153 are slidably connected to another rod in each rod group. The four drive sliders 153 are fixed relative to the main body 151, so that the four drive sliders 153 can move synchronously with the lifting action of the main body 151. The linkage group 16 is also connected to the drive sliders 153 to switch from the unfolded state to the folded state as the drive sliders 153 slide.

[0040] When it is necessary to move table frame 100 from Figure 4 The fully unfolded state shown, folded to Figure 8In the folded state shown, the user can lift the main body 151 in one direction, causing the four drive sliders 153 connected to the main body 151 to slide synchronously on their respective rods. The sliding of each drive slider 153 drives the connected folding drive rod 154 to rotate around a fixed point, thus causing two rods within the four rod groups to rotate to a close-fitting state. Simultaneously, the sliding of the drive sliders 153 also drives the linkage rod group 16 between the two support frames to switch from the unfolded state to the folded state, so that the first and second support frames move closer together. In this state, when further lifting the rest of the table frame 100 via the main body 151, the two rotatably connected rod groups recoil under their own weight. Thus, folding the table frame 100 is simple; the user only needs to lift the main body 151. Furthermore, in the folded state, the eight rods of the four rod groups are close together, and the overall size of the table frame 100 is relatively small, making it convenient to carry and store.

[0041] Continue to refer to Figure 4 As shown, the first rod group 11 includes a first rod 111 and a second rod 112 rotatably connected, and the two rods are rotatably connected by a first rotating connector 113; the second rod group 12 includes a third rod 121 and a fourth rod 122 rotatably connected, and the two rods are rotatably connected by a second rotating connector 123; the third rod group 13 includes a fifth rod 131 and a sixth rod 132 rotatably connected, and the two rods are rotatably connected by a third rotating connector 133; the fourth rod group 14 includes a seventh rod 141 and an eighth rod 142 rotatably connected, and the two rods are rotatably connected by a fourth rotating connector 143.

[0042] The first rotating connector 113 is rotatably connected to the second rotating connector 123, thereby making the first rod group 11 and the second rod group 12 rotatably connected; the third rotating connector 133 is rotatably connected to the fourth rotating connector 143, thereby making the third rod group 13 and the fourth rod group 14 rotatably connected.

[0043] Of the eight members mentioned above, the first member 111, the third member 121, the fifth member 131, and the seventh member 141 are used together for support. Figures 1 to 3 The tabletop 200 has four roughly coplanar members, which allows the tabletop 200 to be stably supported and the tabletop to remain basically level, meeting the user's needs for placing items. The lower ends of the second member 112, the fourth member 122, the sixth member 132, and the eighth member 142 are jointly supported on the external plane.

[0044] In some embodiments, the table frame 100 includes two sets of linkage assemblies 16. (See reference) Figure 3 The table shown has two sets of linkage assemblies 16 spaced apart along the length of the tabletop 200. (Reference) Figure 4As shown in the markings, taking the linkage group 16 between the first linkage group 11 and the third linkage group 13 as an example, the linkage group 16 includes a first linkage 161 and a second linkage 162 that are arranged in a cross configuration. The two linkages are rotatably connected at the intersection to form a scissor arm structure.

[0045] The upper end of the first linkage rod 161 is rotatably connected to the drive slider 153 slidably connected to the second rod 112; the lower end of the first linkage rod 161 is rotatably connected to the sixth rod 132, and the upper end of the second linkage rod 162 is rotatably connected to the drive slider 153 slidably connected to the sixth rod 132, while the lower end of the second linkage rod 162 is rotatably connected to the second rod 112. Thus, when the drive slider 153 slides on its slidably connected rod, it can drive the first linkage rod 161 and the second linkage rod 162 to rotate relative to each other, thereby switching the linkage rod assembly 16 from the unfolded state to the folded state.

[0046] Similarly, the linkage group 16 located between the second linkage group 12 and the fourth linkage group 14 also includes a first linkage 161 and a second linkage 162 that are arranged in a cross configuration, and the two linkages are rotatably connected at their intersection. Specifically: the upper end of the first linkage 161 is rotatably connected to the drive slider 153 that is slidably connected to the eighth linkage 142, and the lower end of the first linkage 161 is rotatably connected to the fourth linkage 122; the upper end of the second linkage 162 is rotatably connected to the drive slider 153 that is slidably connected to the fourth linkage 122, and the lower end of the second linkage 162 is rotatably connected to the eighth linkage 142.

[0047] It is understandable that a single linkage group 16 can also drive the first support frame and the second support frame to move closer together independently. By using the two linkage groups 16 shown in the figure, the force on each rod of the table frame 100 is more even when it is folded, and the folding effect is more ideal.

[0048] Continue to refer to Figure 4 As shown, the table frame 100 may further include two sets of auxiliary support rods 17 connected between the first rod 111 and the fifth rod 131, and between the third rod 121 and the seventh rod 141, respectively. These two sets of auxiliary support rods 17 assist the two sets of linkage rods 16 to stably maintain the first support frame and the second support frame at a preset distance apart in the unfolded state.

[0049] In the illustrated embodiment, the auxiliary support rod assembly 17 includes a first support rod 171 and a second support rod 172 rotatably connected at one end. Specifically, in the auxiliary support rod assembly 17 disposed between the first rod assembly 11 and the third rod assembly 13, the other ends of the first support rod 171 and the second support rod 172 are rotatably connected to the first rod member 111 and the fifth rod member 131, respectively. Similarly, in the auxiliary support rod assembly 17 disposed between the second rod assembly 12 and the fourth rod assembly 14, the other ends of the first support rod 171 and the second support rod 172 are rotatably connected to the third rod member 121 and the seventh rod member 141, respectively.

[0050] For ease of installation and manufacturing, the table frame 100 may also include four pivot connectors 18, which are fixedly mounted on the first member 111, the third member 121, the fifth member 131, and the seventh member 141, respectively. The four folding drive rods 154 and two support rods in the auxiliary support rod group 17 are rotatably connected to their corresponding members through the pivot connectors 18.

[0051] Furthermore, in order to guide the drive slider 153 to slide along the length direction of the corresponding rod and ensure the accuracy of its sliding motion, grooves are provided on the rods on which the drive slider 153 is located. Figure 4 For example, the diagram shows a groove 1321 on the sixth member 132. Similar grooves are also provided on the other members 112, 122, and 142, but they are not all shown or marked in the diagram.

[0052] The folding assembly 15 also includes a lifting portion 152 fixed to the upper side of the main body 151, which is used to lift the main body 151 upward to drive the four drive sliders 153 to slide. Figure 4 As shown, the main body 151 can be configured as a flexible fabric block, with flexible connecting rings fixed at the four corners of the fabric block. The four drive sliders 153 can be connected to the main body 151 through the four connecting rings respectively. In this way, the connection between the main body 151 and the drive sliders 153 is more convenient, which is beneficial to the assembly and manufacturing of the entire folding assembly 15.

[0053] In other embodiments, the main body 151 may also be configured as other flexible and foldable components such as a flexible rope, as long as it can connect to the four drive sliders 153 and simultaneously drive the four drive sliders 153 to slide in the manner described above when lifted.

[0054] Furthermore, the lifting portion 152 can also be configured as a flexible strip structure. Besides the lifting portion 152, this flexible strip can extend to both ends of the main body 151. At each end of the flexible strip, two mating portions of a fastening connector 155, such as a buckle, can be provided. Figure 8As shown, when the eight rods are close together and the table frame 100 is in a folded state, the main body 151 can surround all the rods and fix the table frame 100 in the folded state by fixing the two mating parts in the fixing connector 155.

[0055] The following is for reference Figure 5 , Figure 6 and Figure 7 As shown in the figure, the specific folding process of the table frame 100 in this application is given: After removing the table board 200 from the table, since the lifting part 152 is provided on the upper side of the main body 151, the user can lift the lifting part 152 upward from the middle of the area enclosed by the first rod 111, the third rod 121, the fifth rod 131 and the seventh rod 141, thereby lifting the main body 151 upward.

[0056] The deformation process of the main body 151 after being lifted upwards is roughly as follows: Figure 5 As shown, from Figures 4 to 5 As the main body 151 is gradually lifted, the four drive sliders 153 connected to the main body 151 via four connecting rings slide along their respective grooves, driving the stacking drive rod 154 to rotate around its connection with each pivot connector 18. As the stacking drive rod 154 rotates, the two rods in each rod group move closer to each other. At the same time, the linkage rod group 16 connected to the drive slider 153 also gradually switches to the stacking state, so that the first support frame and the second support frame move closer to each other.

[0057] from Figure 5 and Figure 6 In the intermediate state shown, lifting the lifting part 152 upwards allows all eight rods to come together. In this state, rotating the main body 151 and the flexible band forming the lifting part 152 to one side fixes the two mating parts of the fixing connector 155 relative to each other. This allows the main body 151, which is connected in a ring shape by the fixing connector 155, to surround all the rods, firmly keeping the table frame 100 in this folded state.

[0058] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Although this application has disclosed preferred embodiments as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall still fall within the scope of the technical solution of this application.
