DETAILED DESCRIPTION

[0018] Please refer to Figures 1-14 An assembled camping table 100 with adjustable table plate, which comprises a table frame 1 and a table plate 2.

[0019] The tabletop 2 is detachably attached to the upper part of the table frame 1, allowing the table frame 1 to be disassembled into a smaller size for easy storage. The modular camping table 100 has three configurations: Figure 1 , Figure 2 , Figure 3 The diagram shows three states: First, Second, and Third. In the First State, three tabletops 2 arranged side-by-side can be configured on the upper part of the table frame 1, with the long side of the tabletops 2 perpendicular to the long side of the table frame 1. In this state, the camping table is used as a wide table. However, in this state, it is not necessary to have three tabletops 2; the middle tabletop 2 can be replaced with a gas stove or other appliance of the same size. In the Second State, the camping table is taller and narrower. In this state, two tabletops 2 arranged side-by-side can be configured on the upper part of the table frame 1, with the long side of the tabletops 2 parallel to the long side of the table frame 1. In this state, the camping table is used as a narrow table. In the Third State, the camping table is at its tallest, and the table frame 1 does not need to have tabletops 2. The upper part of the table frame 1 is folded up and can be used as a clothes rack, etc. In other words, the modular camping table 100 of this application is not limited to a fixed-size, single-purpose table; it can be used as a table of different sizes and heights, or as a multi-purpose tool such as a clothes rack, suitable for camping and other scenarios.

[0020] Hereinafter, the vertical and horizontal directions defined in this application shall be in accordance with Figure 1 and Figure 2 The directions shown are defined as follows: the upper side of table frame 1 is up, the lower side of table frame 1 is down, the long side of table frame 1 is horizontal, and the short side of table frame 1 is vertical.

[0021] like Figure 4 As shown, the tabletop 2 includes a rectangular flat plate 21, a long side 22 formed by bending downward from the long side of the flat plate 21, and a short side 23 formed by bending downward from the short side of the flat plate 21.

[0022] The long side 22 includes a long side vertical portion 221 and a long side horizontal portion 222. The long side vertical portion 221 is a portion that remains vertical, formed by bending the entire long side of the plate 21 downwards; while the long side horizontal portion 222 is a portion that remains horizontal, formed by extending the edge of the long side vertical portion 221 inwards. The long side horizontal portion 222 does not extend along the entire length of the long side vertical portion 221, but only extends a portion; the long side horizontal portion 222 includes a horizontal end portion 222a and a horizontal middle portion 222b; wherein, the horizontal end portion 222a is a section that extends inwards from the end of the long side vertical portion 221 located on the short side; while the horizontal middle portion 222b is a section that extends inwards from the middle side of the long side vertical portion 221, a distance away from the horizontal end portion 222a.

[0023] The short side 23 includes a short side vertical portion 231 and a short side horizontal portion 232. The short side vertical portion 231 is a portion that remains vertical, formed by bending the entire short side of the plate 21 downwards; while the short side horizontal portion 232 is a portion that remains horizontal, formed by extending the entire edge of the short side vertical portion 231 inwards.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the table frame 1 includes two tabletop frames 4, four table leg frames 5, and two adapters 6.

[0025] The table frame 4 includes a support 41 and a pin plug 42.

[0026] like Figure 5 As shown, the support 41 is a cylindrical rod structure, including a straight rod 41a extending laterally and a bent rod 41b that bends downward from one end of the straight rod 41a and extends downward for a certain length, and then bends further inward laterally and extends for a certain length.

[0027] Each straight rod 41a is equipped with six tabletop positioning pins 43. Figure 6 This is a bottom view of the assembled camping table 100 in its first state, where the table frame 4 is represented by dashed lines except for the table positioning pin 43. Figure 7 This is a bottom view of the assembled camping table 100 in its second state. Except for the table positioning pin 43, the table frame 4 is represented by dashed lines.

[0028] Specifically, a tabletop positioning pin A 433 is provided at a distance of the first length L1 from the center of the straight rod 41a; a tabletop positioning pin B 432 is provided at a distance of the second length L2 from the center of the straight rod 41a; and a tabletop positioning pin C 431 is provided at a distance of the third length L3 from the center of the straight rod 41a.

[0029] The following is a structural description of the first state of the assembled camping table 100: Figure 6 and Figure 1 In the first state shown, the short side 23 of the flat plate 21 is parallel to the straight rod 41a, allowing the three tabletops 2 to be placed on the straight rod 41a. At this time, as... Figure 6 As shown, the second length L2 of the tabletop positioning pin 432 from the transverse center line of the straight rod 41a is slightly greater than the distance from the center of the short side 23 of the tabletop 2 to the end point of the long side. That is, twice the length of L2 is only slightly longer than the length of the short side of the tabletop 2.

[0030] Therefore, as Figure 6As shown, in the first state, the tabletop positioning pin 432 is positioned between the horizontal end 222a and the horizontal middle portion 222b of the outer tabletop 2, and is abutted by the vertical portion 221 of the long side, thus achieving lateral limitation of the outer tabletop. That is, the vertical portions 221 of the long sides 22 of the two tabletops 2 on both sides are restricted from moving outward away from the lateral center by the tabletop positioning pin 432, while movement towards the center is restricted by the tabletop 2 in the middle position. The lateral movement of the middle tabletop 2 is restricted by the two tabletops on both sides. Therefore, the lateral movement of the tabletop 2 is restricted.

[0031] Furthermore, in the first state, the tabletop positioning pins 43 are all located inside the short side horizontal portion 232 provided on the short side 23 of the tabletop 2, so that the movement of the tabletop 2 in the longitudinal direction is restricted by the tabletop positioning pins 43.

[0032] The following is a structural description of the second state of the assembled camping table 100: (as follows) Figure 7 and Figure 2 In the second state shown, the long side 22 of the flat plate 21 of the tabletop 2 is adjusted to be parallel to the straight rod 41a, so that the two tabletops 2 can be placed on the straight rod 41a. At this time, as Figure 7 As shown, the length between the center of the tabletop positioning pin 433 and the center of the straight rod 41a is the first length L1. This length is the distance measured from one short side of the tabletop 2, extending to the horizontal middle portion 222b of the other short side, slightly beyond its position; that is, the tabletop positioning pin 433 abuts against the outside of the horizontal middle portion 222b, restricting the outward lateral movement of the outer tabletop 2. Furthermore, as... Figure 7 As shown, the distance from the center of the straight rod 41a to the third length L3 of the tabletop positioning pin C 431 is the length measured from one short side of the tabletop 2 to a position slightly closer to the horizontal middle part 222b on the other short side; that is, the tabletop positioning pin C 431 abuts against the inner side of the horizontal middle part 222b, restricting the inward lateral movement of the outer tabletop 2. In addition, L1 + L3 is equal to the length of the long side of the tabletop 2.

[0033] In the second state, the horizontal middle part 222b of the tabletop 2 is restricted from moving laterally outward by the tabletop positioning pin A 433, while the movement to the other lateral side is restricted by the tabletop positioning pin C 431.

[0034] In the second state, the vertical portion 221 of the long side of the tabletop 2 is restricted from moving longitudinally by the tabletop positioning pin 43. Therefore, the movement of the tabletop 2 in the width direction is restricted.

[0035] In summary, depending on the specific implementation, in both the first and second states, the tabletop positioning pin 43 achieves both the positioning of the tabletop 2 and prevents the tabletop 2 from falling off the tabletop frame 4.

[0036] Figure 8 yes Figure 3 The sectional view along line AA shown is a cross-sectional view of the front end of the bent rod 41b and the adapter 6. (See diagram below.) Figure 5 and Figure 8 As shown, the portion of the bent rod 41b parallel to the straight rod 41a (i.e., the end portion of the bent rod 41b) has through pin holes 44a and screw holes 44b on its outer periphery. The adapter 6 is located between the two tabletop frames 4, and each adapter 6 connects to two bent rods 41b on the same side of the two tabletop frames 4.

[0037] The pin plug 42 is a cylindrical component of a specified length, with hollow cylindrical ends. The outer circumference of the pin plug 42 has a movable hole 42a and a threaded hole 42b in the radial direction. A flange ring 42c is fixed to the outer end 400 of the pin plug 42. The outer diameter of the pin plug 42 is approximately equal to the inner diameter of the bent rod 41b, while the outer diameter of the flange ring 42c is approximately equal to the outer diameter of the bent rod 41b.

[0038] When the pin plug 42 is inserted into the bent rod 41b, the flange ring 42c contacts the end of the bent rod 41b, thus preventing the pin plug 42 from penetrating further. At this time, the movable hole 42a of the pin plug 42 is located directly below the pin hole 44a of the bent rod 41b, and the threaded hole 42b of the pin plug 42 is located directly below the screw hole 44b of the bent rod 41b.

[0039] like Figure 9 As shown, the table leg 5 includes an upper frame rod 51, a lower frame rod 52, foot pads 53, hooks 55, and connecting ropes 56. The upper end of the lower frame rod 52 is slidably embedded in the lower end of the upper frame rod 51, so that the overall height of the table leg 5 can be adjusted.

[0040] The lower support rod 52 is cylindrical, and a locating pin 52a is installed on its upper side. The locating pin 52a is elastically applied to protrude from the outer surface of the upper end of the lower support rod 52. The upper support rod 51 has two locating pin holes 51c on its outer periphery, both of which can mate with the locating pin 52a. The foot pad 53 is installed at the lower end of the lower support rod 52.

[0041] When table leg 5 is in its shortest position (e.g.) Figure 3 (As shown in the diagram), except for the area where the foot pads 53 are installed, the rest of the lower frame rod 52 is inside the upper frame rod 60. The positioning pin 52a is inserted into the positioning pin hole 51c above the straight rod portion 51a, maintaining the short leg position. When the table leg 5 is in its longest position (as shown in the diagram),... Figure 1 (or as shown in Figure 2), most of the lower support rod 52 extends outward from the lower part of the upper support rod 51, and the positioning pin 52a is inserted into the positioning pin hole 51c on the lower side of the straight rod part 51a to maintain the long leg state.

[0042] like Figure 9As shown, the two ends of the hook 55 are respectively set at the straight rod portion 51a of the two upper frame rods 51, and are erected across the outer surface of one upper frame rod 51 and the outer surface of the other upper frame rod 51.

[0043] One end of the connecting rope 56 is fixedly connected to the straight rod portion 51a of the upper frame rod 51, and the other end extends through the interior of the upper frame rod 51 to the upper end of the bent rod portion 51b and is exposed at its opening.

[0044] The adapter 6 is located between the two tabletop frames 4. One end of each adapter 6 is connected to two table legs 5, while the other end of each adapter 6 is simultaneously connected to the bent rod 41b on the same side of both tabletop frames 4. Figure 10 As shown, the adapter 6 includes a mounting base 61 and an angle retaining cover 62.

[0045] The mounting base 61 is divided into two parts in the horizontal direction: a tabletop frame connecting part 61A and a table corner frame connecting part 61B. The mounting base 61 has two horizontally arranged and parallel bracket insertion holes 61a inside. A limiting wall 61b is fixedly installed on the inner wall of the middle of the bracket insertion hole 61a, and a through hole is formed in the center of the limiting wall 61b to connect the bracket insertion holes 61a on both sides. The horizontal section of the bent rod 41b is embedded in the bracket insertion hole 61a on one side of the tabletop frame connecting part 61A. The horizontal section of the bent rod 51b is embedded in the bracket insertion hole 61a on one side of the table corner frame connecting part 61B. Both horizontal sections abut against the end face of the limiting wall 61b to ensure complete assembly.

[0046] One end of the connecting rope 56 has a knot that passes through a hole in the limiting wall 61b. The knot is larger than the hole diameter, so that one end of the connecting rope 56 is fixed inside the adapter 6. Therefore, when the table leg 5 is removed from the adapter 6, the table leg 5 will not completely separate from the adapter 6; the connecting rope 56 keeps the table leg 5 connected to the adapter 6. In other words, the table leg 5 can be compactly stored by pulling it out of the adapter 6; because the connecting rope 56 keeps the table leg 5 connected to the adapter 6, it will not fall apart, making reassembly easier. The connecting rope 56 can be made of elastic rubber.

[0047] like Figure 11 As shown, several symmetrically arranged insertion protrusions 61c are fixedly provided on the inner wall of the bracket insertion hole 61a of the table leg connecting part 61B. The insertion protrusions 61c extend outward from the end face of the limiting wall 61b. Symmetrically arranged cuts 54 are opened on the end face of the bent rod part 51b, and the cuts 54 match the insertion protrusions 61c. When the bent rod part 51b is inserted into the bracket insertion hole 61a, the cuts 54 and the insertion protrusions 61c match and limit the movement, and the angle between the two table legs 5 installed on the single adapter 6 will form a fixed angle θ, which facilitates support.

[0048] like Figure 8 and Figure 10 As shown, a protruding hanging piece 61d is fixedly installed at the lower end of the fixing base 61 on the side of the table frame connecting part 61A. The hook 55 can be hooked onto the hanging piece 61d. This prevents the table leg frame 5 from falling off the fixing base 61.

[0049] like Figure 10 As shown, the bracket insertion hole 61a at the table frame connecting part 61A has an open upper part, and the angle retaining cover plate 62 is installed at the opening to form a complete hole. The angle retaining cover plate 62 is a U-shaped thin plate component, and the angle retaining cover plate 62 is installed at the upper end of the opening of the bracket insertion hole 61a at the table frame connecting part 61A by cover plate screws 62a.

[0050] On the angle-holding cover plate 62, two elongated holes 62b, which serve as first angle adjustment holes, are provided symmetrically on both sides in the longitudinal direction. The elongated holes 62b are oblong in shape. On the angle-holding cover plate 62, in front of the elongated holes 62b (in the transverse direction on the side where the bracket 41 is inserted), a first positioning hole 62c, which serves as a second angle adjustment hole, is provided. Furthermore, on the upper side of one of the first positioning holes 62c, a second positioning hole 62d, which serves as a third angle adjustment hole, is provided parallel to the first positioning hole 62c. The first positioning hole 62c and the second positioning hole 62d are located on the same loop line to facilitate switching and assembly of the positioning holes when the bent rod 41b rotates.

[0051] Figure 12 This is a structural diagram of the adapter at point 6 in the first state. Figure 13 This is a structural diagram of connector 6 in the second state. Figure 14 This is a structural diagram of connector 6 in the third state.

[0052] Specifically, such as Figure 12 and Figure 1 As shown, in the first state, the distance between the two straight rods 41a reaches its maximum value, the first distance M1, and the angle between the two bent rods 41b is the first angle α1. At this time, the pin 45a is not located in the first positioning hole 62c or the second positioning hole 62d, therefore it is not in... Figure 12 As shown, at this time, the pin 45a is pressed against the inner surface of the angle-holding cover plate 62. Since the screw 45b is screwed into the threaded hole 42b, the head of the screw 45b protrudes from the screw hole 44b and slides within the elongated hole 62b. In this state, the screw 45b abuts against the inner wall of the outermost part of the elongated hole 62b, limiting its position so that the angle between the two tabletop supports 4 does not exceed α1. At this time, as... Figure 1 As shown, the tabletop 2 can be configured by arranging the short side 23 parallel to the straight rod 41a to achieve a combination configuration of three tabletops 2.

[0053] like Figure 13 and Figure 2As shown, in the second state, the distance between the two straight rods 41a is a second distance M2, which is less than the first distance M1; the angle between the two bent rods 41b is a second angle α2, which is less than the first angle α1. At this time, the pin 45a protrudes outward, passes through the pin hole 44a, and is located in the first positioning hole 62c, thus achieving positioning. The screw 45b is always located in the elongated hole 62b to limit the sliding position and help the table frame 4 to rotate smoothly to the position where the pin 45a and the first positioning hole 62c are engaged. Thus, the angle between the two bent rods 41b is maintained at the second angle α2. At this time, as Figure 2 As shown, the tabletop 2 can be configured by arranging the long side 22 parallel to the straight rod 41a, thus achieving a combination configuration of two tabletops 2.

[0054] like Figure 14 and Figure 3 As shown, in the third state, the distance between the straight rods 41a is less than the second distance M2 but equal to the third distance M3. At this time, the two table frame members 4 are flipped upwards and closed, and the bent rods 41b are parallel to each other. One of the pins 45a is located at the position of the second positioning hole 62d and protrudes outward from the second positioning hole 62d. Thus, the table frame 1 can be used as a clothes hanger.

[0055] According to the table frame 1 and the assembled camping table 100 of this embodiment, since the opening angles of the two bent rods 41b are different, the effective area used as a tabletop is variable, and the height of the table legs and the height of the tabletop are also adjustable, thereby realizing a multi-functional application that can be used for purposes such as clothes hangers in addition to the function of a tabletop.

[0056] In this embodiment, a configuration of four table legs 5, consisting of two legs on each of the two sides in the horizontal direction, is described. However, the invention is not limited to this configuration. For example, the two table legs 5 on each side in the horizontal direction can be connected at their lower ends. Furthermore, the two table legs 5 arranged on each side in the longitudinal direction can also be connected to each other at their lower ends.

[0057] In this embodiment, a notch 54 is provided at the upper end of the upper frame rod 51 of the table leg 5, and a plug-in protrusion 61c is provided at the connecting part of the table leg 5 in the adapter 6, which cooperates with the notch 54 to achieve a concave-convex plug-in fit. However, the present invention is not limited to this, for example, the concave-convex shape of the notch 54 and the plug-in protrusion 61c can be interchanged.

[0058] In this embodiment, a hook 55 connected to the adapter 6 is provided between the two table legs 5 on the same side. However, the invention is not limited to this; for example, the hook 55 may also be a spring component or a rivet component.
