Description

Technical Field

[0001] This invention relates to the field of folding support technology, and more particularly to a folding support and camping bed. Background Technology

[0002] In existing technologies, the design of folding brackets often faces a common challenge: how to minimize their volume in the folded state, especially reducing the lateral space occupied, while ensuring the stable support performance of the bracket.

[0003] Traditional folding tripods mostly use linear or planar structures. While these structures can achieve folding to some extent, they still occupy a considerable amount of space when folded, making them inconvenient to carry and store. Especially for outdoor adventures, travel, or everyday use, users have higher requirements for the portability and folding efficiency of folding tripods.

[0004] However, existing folding bracket designs often struggle to simultaneously meet the demands for stable support and convenient folding. On one hand, to ensure the bracket's support performance, its structure is often quite complex, resulting in a large volume when folded. On the other hand, reducing the folded volume may sacrifice the bracket's support stability. Therefore, how to minimize the bracket's volume in its folded state, especially reducing the lateral space it occupies, without sacrificing its support performance, has become an urgent technical problem to be solved.

These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0025] Please see Figures 1 to 10 This embodiment discloses a folding bracket, comprising: The column 10 includes: a telescopic rod 11, a first connector 12, and a second connector 13; the first connector 12 and the second connector 13 are respectively located at both ends of the telescopic rod 11. The support frame 20 includes: a first support crossbar 21, a first support rod 22, and a second support rod 23; the first support crossbar 21 is rotatably connected to the first connector 12. The first support rod 22 and the second support rod 23 are rotatably connected, and one end of the first support rod 22 is rotatably connected to the first connector 12; one end of the second support rod 23 is rotatably connected to the second connector 13, and the other end of the second support rod 23 is rotatably connected to the first support crossbar 21. The first support rod 22 includes a first rod body 231 and a second rod body 232; the end of the first rod body 231 is rotatably connected to the end of the second rod body 232, and the end of the first rod body 231 away from the second rod body 232 is rotatably connected to the first support crossbar 21, and the end of the second rod body 232 away from the first rod body 231 is rotatably connected to the second connector 13.

[0026] The telescopic rod 11 is vertically arranged. When the folding bracket is extended, the telescopic rod 11 returns to its original position, i.e., its first state; when folded, it is stretched, i.e., its second state. The first connecting member 12 is located at the top of the telescopic rod 11; for details, please refer to [link to relevant documentation]. Figure 6The first connecting member 12 includes: a first clamping plate 121, a second clamping plate 122, and a protrusion 123. The first clamping plate 121 and the second clamping plate 122 are disposed opposite to each other, forming a clamping channel 124 between them, and the first clamping plate 121 and the second clamping plate 122 are interconnected. The protrusion 123 is located on the side of the first clamping plate 121 away from the second clamping plate 122.

[0027] The protrusion 123 is built into the first fixing groove 125, the first fixing groove 125 is adapted to the top end of the telescopic rod 11, and the top end of the telescopic rod 11 is fixed in the first fixing groove 125.

[0028] Please see Figure 5 The second connector 13 is placed at the bottom of the telescopic rod 11. The second connector 13 is provided with a second fixing groove 131 and a through groove 132. The second fixing groove 131 is adapted to the bottom of the telescopic rod 11, and the bottom of the telescopic rod 11 is fixedly disposed in the second fixing groove 131. Furthermore, the distance between the through groove 132 and the second fixing groove 131 is adapted to the clamping channel 124.

[0029] The first support crossbar 21 is rotatably connected to the first connector 12; specifically, the top end of the first support crossbar 21 is positioned between the first clamping plate 121 and the second clamping plate 122, and the top end of the first support crossbar 21 is rotatably connected to the first clamping plate 121 and / or the second clamping plate 122; when the telescopic rod 11 is in the first state, the first support crossbar 21 is horizontally positioned, and when the telescopic rod 11 switches from the first state to the second state, the first support crossbar 21 rotates in the direction of the telescopic rod 11.

[0030] The first support rod 22 and the second support rod 23 are rotatably connected, forming an X-shape. Preferably, the middle portion of the first support rod 22 is rotatably connected to the middle portion of the second support rod 23. One end of the first support rod 22 is positioned between the first clamping plate 121 and the second clamping plate 122, and one end of the first support rod 22 is rotatably connected to the first clamping plate 121 and / or the second clamping plate 122.

[0031] One end of the second support rod 23 is rotatably connected to the inner wall of the through groove 132.

[0032] The first rod 231 and the second rod 232 have an obtuse angle with an opening facing the first connector 12, so that the first rod 231 can obtain sufficient support in the first state of the folding bracket. When the end of the first support crossbar 21 away from the first connector 12 is pressed down, the first rod 231 and the second rod 232 can be folded in the opposite direction of the obtuse angle, so that the first support crossbar 21 can continue to rotate downward. Specifically, the first rod 231 and the second rod 232 are connected by the fifth connector. The end of the first rod 231 near the second rod 232 is rotatably connected to the fifth connector, and the end of the second rod 232 near the first rod 231 is rotatably connected to the fifth connector. There is a gap between the first rod 231 and the second rod 232, and the extensions of the first rod 231 and the second rod 232 intersect to form an obtuse angle.

[0033] The fifth connector consists of two opposing fifth clamping plates, with the first rod 231 and the second rod 232 positioned between the two fifth clamping plates.

[0034] Unlike existing technologies, the above technical solution, through the arrangement of the telescopic rod 11, allows the first support crossbar 21, the first support rod 22, and the second support rod 23 to rotate towards the telescopic rod 11 when the folding bracket is folded, making full use of the vertical space of the folding bracket and thus reducing the use of lateral space; at the same time, by staggering the second support rod 23, the first support crossbar 21, and the telescopic rod 11, the second support rod 23, the first support crossbar 21, and the telescopic rod 11 can overlap, avoiding mutual restriction and thus reducing the volume of the folding bracket in the second state.

[0035] According to some embodiments of this application, refer to Figures 2 to 3 The support frame 20 further includes: a second support crossbar 24, a third support rod 25 and a fourth support rod 26; The second support crossbar 24 is rotatably connected to the end of the first support crossbar 21 away from the first connector 12; The third support rod 25 and the fourth support rod 26 are rotatably connected; one end of the third support rod 25 is connected to the second support crossbar 24, and the other end is connected to the end of the first support rod 22 away from the first connector 12. When the telescopic rod 11 is pulled, the first support crossbar 21 and the second support crossbar 24 fold together.

[0036] The second support crossbar 24 and the first support crossbar 21 are rotatably connected via a third connector 27. For details, please refer to [link / reference]. Figure 9The third connecting member 27 includes: a first connecting rod 271 and a second connecting rod 272. One end of the first connecting rod 271 has a first abutting surface, and one end of the second connecting rod 272 has a second abutting surface. In a first state, the first abutting surface is in contact with the second abutting surface. The upper part of the first abutting surface is hinged to the upper part of the second abutting surface.

[0037] The end of the first support crossbar 21 near the second support crossbar 24 is sleeved on the first connecting rod 271, and the end of the second support crossbar 24 near the first support crossbar 21 is sleeved on the second connecting rod 272.

[0038] The third connecting member 27 further includes: a guard plate 273, the guard plate 273 being placed on both sides of the first supporting crossbar 21 near the second supporting crossbar 24 and the guard plate 273 being placed on both sides of the second supporting crossbar 24 near the first supporting crossbar 21, the guard plate 273 on the first supporting crossbar 21 and the guard plate 273 on the second supporting crossbar 24 being rotatably connected; that is, the guard plate 273 on the first supporting crossbar 21 moves synchronously with the first connecting rod 271, and the guard plate 273 on the second supporting crossbar 24 moves synchronously with the second connecting rod 272.

[0039] During the process of switching the folding bracket from the first state to the second state, the side of the first support crossbar 21 closest to the second support crossbar 24 rotates away from the connection between the first connecting rod 271 and the second connecting rod 272, that is, it rotates downward; the rotation direction of the second support crossbar 24 is the same; so as to realize the folding of the first support crossbar 21 and the second support crossbar 24.

[0040] The third support rod 25 and the fourth support rod 26 are rotatably connected, forming an X-shape. Preferably, the middle portion of the third support rod 25 is rotatably connected to the middle portion of the fourth support rod 26. Further, one end of the third support rod 25 is rotatably connected to the second support crossbar 24, and the other end of the third support rod 25 is rotatably connected to the first support rod 22.

[0041] Furthermore, one end of the fourth support rod 26 is in contact with the ground to support the folding bracket; the other end, in the first state, is flush with or higher than the upper surface of the second support crossbar 24. Since the fabric is connected to the first support crossbar 21 and the second support crossbar 24, in the second state, the end of the fourth support rod 26 away from the ground can be used to support the fabric.

[0042] It should also be noted that, please refer to Figure 10It also includes: a fourth connector 28, wherein the third support rod 25 is connected to the first support rod 22 via the fourth connector 28; specifically, the fourth connector 28 includes: a foot pad 281, a third clamping plate 282, and a fourth clamping plate 283; the third clamping plate 282 and the fourth clamping plate 283 are L-shaped, and both ends of the third clamping plate 282 are rotatably connected to the foot pad 281 and the first support rod 22, respectively; specifically, there are two third clamping plates 282, which are arranged opposite to each other, wherein the third... One end of a support rod 22, away from the first connecting member 12, is positioned between the two third clamping plates 282. A pivot shaft passes through the third clamping plate 282, the first support rod 22, and the other third clamping plate 282 in sequence. There are two fourth clamping plates 283, arranged opposite each other. One end of a third support rod 25, away from the second support crossbar 24, is positioned between the two fourth clamping plates 283. A pivot shaft passes through the fourth clamping plates 283, the third support rod 25, and the other fourth clamping plate 283 in sequence. A foot pad 281 is used to support the folding bracket on the ground, with both ends positioned between the two third clamping plates 282 and between the two fourth clamping plates 283, respectively.

[0043] During operation, when the column 10 switches from the first state to the second state, the end of the first support crossbar 21 connected to the first connector 12 moves upward, and at the same time, the end of the first support rod 22 near the first connector 12 moves upward synchronously; causing the other end of the first support crossbar 21 and the first support rod 22 to rotate toward the column 10.

[0044] While the first support crossbar 21 rotates, the first support crossbar 21 presses down on the second support crossbar 24, causing the first support crossbar 21 and the second support crossbar 24 to fold together until the first support crossbar 21 and the second support crossbar 24 are in close contact with each other; at the same time, the first support crossbar 21 drives the first rod body 231 to rotate downward, causing the first rod body 231 and the second rod body 232 to fold together.

[0045] During the folding process of the second support crossbar 24 and the first support crossbar 21, the second support crossbar 24 drives the third support bar 25 to rotate towards the first support bar 22.

[0046] According to some embodiments of this application, refer to Figure 3The support frames 20 are symmetrically arranged on both sides of the column 10. The two support frames 20 are connected to the column 10 in the same way, which will not be described again here. It should be noted that when the telescopic rod 11 changes from the first state to the second state (the telescopic rod 11 is stretched), the support frames 20 on both sides of the column 10 fold simultaneously.

[0047] According to some embodiments of this application, refer to Figure 7 as well as Figure 11 The telescopic rod 11 includes an outer tube 111, an inner tube 112, and a first elastic element. The outer tube 111 is sleeved on the inner tube 112. The inner tube 112 is movably disposed relative to the outer tube 111. The two ends of the first elastic element are respectively located on the side of the inner tube away from the end of the outer tube and on the side of the outer tube away from the end of the inner tube. The first elastic element is used to reset the telescopic rod. When the inner tube extends out of the outer tube, the first elastic element is in a stretched state.

[0048] When the inner tube 112 extends out of the outer tube 111, the first elastic element is in a stretched state. The first elastic element is a spring, rubber band, cylinder, or hydraulic rod.

[0049] The outer tube 111 is slidably sleeved on the inner tube 112. The outer tube 111 is connected to the first connector 12, and the inner tube 112 is connected to the second connector 13. That is, the top end of the outer tube 111 is adapted to the first fixing groove 125 and the outer tube 111 is fixed in the first fixing groove 125 of the first connector 12. The bottom end of the inner tube 112 is adapted to the second fixing groove 131 and the inner tube 112 is fixed in the second fixing groove 131 of the second connector 13.

[0050] The first elastic element is a spring or rubber band, or other elastic object. Both ends of the first elastic element are connected to the inner tube 112 and the outer tube 111, respectively. The two ends of the first elastic element are the end of the outer tube 111 furthest from the inner tube 112 and the end of the inner tube 112 furthest from the outer tube 111. In other embodiments, one end of the first elastic element is connected to the outer tube 111, and the other end is connected to the second connecting member 13; or one end of the first elastic element is connected to the inner tube 112, and the other end is connected to the first connecting member 12.

[0051] When the inner tube 112 extends beyond the outer tube 111, the folding bracket is in its second state, and the first elastic element is in a stretched state to store elastic force. When the folding bracket needs to be unfolded, the user only needs to lightly press the telescopic rod 11, and the inner tube 112 and the outer tube 111 will move closer together under the action of elastic force. The first elastic element enables the folding bracket to unfold automatically.

[0052] According to some embodiments of this application, refer to Figure 4 , Figure 6 as well as Figure 7 The column 10 further includes a handle 14, which is placed on the first connector 12.

[0053] The handle 14 is placed on the column 10 to facilitate the user's operation of the folding bracket; specifically, the handle 14 is a vertically arranged ring handle 14, and the handle 14 is placed on the side of the second clamping plate 122 away from the first clamping plate 121.

[0054] According to some embodiments of this application, refer to Figure 4 , Figure 6 as well as Figure 7 The column 10 further includes: a storage protrusion 15; The placement protrusion 15 is placed on the first connector 12, and the placement protrusion 15 is provided with a plurality of through holes 151, which are used to accommodate objects.

[0055] The placement protrusion 15 is placed on the column 10, facilitating the user to hang objects on the folding bracket. Specifically, the placement protrusion 15 is a protrusion extending from the column 10, and it is positioned on the side of the second clamping plate 122 away from the first clamping plate 121. The placement protrusion 15 has a through hole 151 that penetrates the placement protrusion 15 and is vertically positioned for hanging objects.

[0056] Please see Figures 1 to 11 This embodiment provides a camping bed, including: the folding bracket as described in any one of claims 1 to 8 and the connecting frame 30; The folding bracket consists of two folding brackets arranged symmetrically, with the connecting frame positioned between the two folding brackets, and each end of the connecting frame 30 connected to one of the folding brackets.

[0057] Folding refers to the process of switching from the first state to the second state. That is, during the process of switching from the first state to the second state, the connecting frame located in the middle reduces the distance between the two folding brackets by shrinking or folding, so as to achieve the purpose of folding the camping bed.

[0058] In other embodiments, a camping bed further includes: a bed sheet; the length of the bed sheet is adapted to the length of the folding bracket in the first state, and the width of the bed sheet is adapted to the length of the connecting frame when unfolded; further, the bed sheet is fitted onto the first support crossbar 21 and the second support crossbar 24 on opposite sides; the bed sheet can be folded accordingly when folded.

[0059] According to some embodiments of this application, refer to Figure 7 and Figure 8 The connecting frame 30 is a folding frame or a telescopic support.

[0060] In some embodiments, the telescopic bracket is a telescopic rod, and when folding is required, the distance between two oppositely arranged folding brackets can be reduced by compressing the telescopic rod.

[0061] In other embodiments, the folding frame includes a first folding rod 31, a second folding rod 32, a third folding rod, and a fourth folding rod. The first folding rod 31 and the second folding rod 32 are rotatably connected at their midpoints to form an X-shape, as are the third and fourth folding rods. One end of the first folding rod 31 is rotatably connected to the folding bracket, and the other end is rotatably connected to the fourth folding rod. Similarly, one end of the second folding rod 32 is rotatably connected to the folding bracket, and the other end is rotatably connected to the third folding rod. Further, the first folding rod 31 and the third folding rod are on the same plane, as are the second folding rod 32 and the fourth folding rod. When folding is required, the first folding rod 31 and the third folding rod move closer to each other, and the second folding rod 32 and the fourth folding rod move closer to each other.

[0062] In other embodiments, a camping bed reset mechanism includes: the folding bracket, a first folding rod 31, a second folding rod 32, and an elastic unit 33; The first folding rod 31 and the second folding rod 32 are rotatably connected, and the first folding rod 31 and the second folding rod 32 form an X-shape, a Y-shape or a V-shape; The first folding rod 31 is rotatably connected to the first connecting member 12, and the second folding rod is rotatably connected to the second connecting member; The two ends of the elastic unit 33 are respectively placed on one side of the first connector 12 and one side of the second connector 13, and the elastic unit 33 is used to reset the folding bracket.

[0063] Specifically, the first folding rod 31 and the second folding rod 32 are rotatable to form an X shape, that is, the middle part of the first folding rod 31 and the middle part of the second folding rod 32 are rotatably connected. When folded, the first folding rod 31 and the second folding rod 32 are closed in the horizontal direction, and when unfolded, the first folding rod 31 and the second folding rod 32 are closed in the vertical direction.
