Description

Technical Field

[0001] The utility model relates to the technical field of bracket folding, in particular to a folding bracket, a camping bed and a camping bed resetting mechanism. Background Art

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

[0003] Traditional folding stands mostly use linear or flat structures. Although these structures can be folded to a certain extent, they still take up a lot of space when folded, making them inconvenient to carry and store. Especially for outdoor adventures, travel, or daily use, users have higher requirements for folding stands' portability and folding efficiency.

[0004] However, existing folding bracket designs often struggle to simultaneously meet the requirements of stable support and convenient folding. On the one hand, to ensure the bracket's support performance, its structure is often complex, resulting in a larger volume when folded. On the other hand, to reduce the folded volume, the bracket's support stability may be sacrificed. Therefore, minimizing the bracket's volume in the folded state without sacrificing its support performance, especially reducing the lateral space occupied, has become a pressing technical challenge.

[0058] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0059] Please refer to Figures 1 to 10 The embodiment discloses a folding support, which comprises:

[0060] A stand 10, the stand 10 comprises a telescopic rod body 11, a first connecting piece 12 and a second connecting piece 13; the first connecting piece 12 and the second connecting piece 13 are respectively arranged at two ends of the telescopic rod body 11;

[0061] The support frame 20 includes a first support cross bar 21, a first support bar 22, and a second support bar 23; the first support cross bar 21 is rotatably connected to the first connecting member 12;

[0062] The first support rod 22 is rotatably connected to the second support rod 23, and one end of the first support rod 22 is rotatably connected to the first connecting member 12; one end of the second support rod 23 is rotatably connected to the second connecting member 13, and the other end of the second support rod 23 is rotatably connected to the first supporting cross bar 21;

[0063] 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 supporting cross bar 21, and the end of the second rod body 232 away from the first rod body 231 is rotatably connected to the second connecting member 13.

[0064] The telescopic rod 11 is vertically arranged and can be restored when the folding bracket is opened, that is, the first state; and can be stretched when folded, that is, the second state. The first connecting member 12 is placed on the top of the telescopic rod 11; for details, please refer to Figure 6 The 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 each other, a clamping channel 124 is formed between the first clamping plate 121 and the second clamping plate 122, and the first clamping plate 121 and the second clamping plate 122 are connected to each other. The protrusion 123 is located on the side of the first clamping plate 121 away from the second clamping plate 122.

[0065] The first fixing groove 125 is built into the protrusion 123 . The first fixing groove 125 is adapted to the top of the telescopic rod 11 . The top of the telescopic rod 11 is fixed in the first fixing groove 125 .

[0066] See also Figure 5 The second connecting member 13 is positioned at the bottom of the telescopic rod 11. The second connecting member 13 is provided with a second fixing slot 131 and a through slot 132. The second fixing slot 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 slot 131. Furthermore, the spacing between the through slot 132 and the second fixing slot 131 is adapted to the clamping channel 124.

[0067] The first supporting cross bar 21 is rotatably connected to the first connecting member 12; specifically, the top end of the first supporting cross bar 21 is placed between the first clamping plate 121 and the second clamping plate 122, and the top end of the first supporting cross bar 21 is rotatably connected to the first clamping plate 121 and / or the second clamping plate 122; when the telescopic rod body 11 is in the first state, the first supporting cross bar 21 is horizontally arranged, and when the telescopic rod body 11 switches from the first state to the second state, the first supporting cross bar 21 rotates toward the telescopic rod body 11.

[0068] 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.

[0069] One end of the second support rod 23 is rotatably connected to the inner wall of the through slot 132 .

[0070] An obtuse angle is formed between the first rod 231 and the second rod 232, with the angle opening facing the first connector 12. This allows the first rod 231 to obtain sufficient support when the folding bracket is in the first state. When the end of the first support cross bar 21 away from the first connector 12 is pressed downward, the first rod 231 and the second rod 232 can be folded in the opposite direction of the obtuse angle, allowing the first support cross bar 21 to 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 closest to the second rod 232 is rotatably connected to the fifth connector, and the end of the second rod 232 closest to 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 extension lines of the first rod 231 and the second rod 232 intersect to form an obtuse angle.

[0071] When the first support rod is a vertical rod, the telescopic rod needs to be lifted to a higher height so that the first support cross bar and the first support rod form a straight line or approach a straight line in the second state.

[0072] The fifth connecting member is two fifth clamping plates arranged opposite to each other, and the first rod 231 and the second rod 232 are placed between the two fifth clamping plates.

[0073] Different from the existing technology, the above technical solution, through the setting of the telescopic rod body 11, enables the first support cross bar 21, the first support rod 22 and the second support rod 23 to rotate toward the telescopic rod body 11 when the folding bracket is folded, thereby fully utilizing the vertical space of the folding bracket and reducing the utilization of the horizontal space; at the same time, through the staggered setting of the second support rod 23, the first support cross bar 21 and the telescopic rod body 11, the second support rod 23, the first support cross bar 21 and the telescopic rod body 11 can overlap to avoid mutual limitation, thereby reducing the volume of the folding bracket in the second state.

[0074] According to some embodiments of the present application, referring to Figures 2 to 3 , the support frame 20 further includes: a second support cross bar 24, a third support bar 25 and a fourth support bar 26;

[0075] The second supporting cross bar 24 is rotatably connected to the end of the first supporting cross bar 21 away from the first connecting member 12;

[0076] 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 cross bar 24, and the other end is connected to the end of the first support rod 22 away from the first connecting member 12;

[0077] When the telescopic rod 11 is pulled, the first supporting cross bar 21 and the second supporting cross bar 24 are folded in half.

[0078] The second support cross bar 24 is rotatably connected to the first support cross bar 21 via a third connecting member 27. For details, please refer to Figure 9 The third connecting member 27 includes: a first connecting rod 271 and a second connecting rod 272. The first connecting rod 271 has a first abutting surface at one end, and the second connecting rod 272 has a second abutting surface at one end. In the first state, the first abutting surface contacts the second abutting surface; the upper part of the first abutting surface is hinged to the upper part of the second abutting surface.

[0079] One end of the first supporting cross bar 21 close to the second supporting cross bar 24 is sleeved on the first connecting rod 271 , and one end of the second supporting cross bar 24 close to the first supporting cross bar 21 is sleeved on the second connecting rod 272 .

[0080] The third connecting member 27 also includes: a guard plate 273, which is placed on both sides of the first support cross bar 21 close to the second support cross bar 24, and the guard plate 273 is placed on both sides of the second support cross bar 24 close to the first support cross bar 21. The guard plate 273 on the first support cross bar 21 and the guard plate 273 on the second support cross bar 24 are rotatably connected; that is, the guard plate 273 on the first support cross bar 21 moves synchronously with the first connecting rod 271, and the guard plate 273 on the second support cross bar 24 moves synchronously with the second connecting rod 272.

[0081] When the folding bracket switches from the first state to the second state, the first support cross bar 21 rotates on the side close to the second support cross bar 24 away from the connection between the first connecting rod 271 and the second connecting rod 272, that is, rotates downward; the rotation direction of the second support cross bar 24 is the same; so as to achieve the folding of the first support cross bar 21 and the second support cross bar 24.

[0082] The third support rod 25 and the fourth support rod 26 are rotatably connected, and the third support rod 25 and the fourth support rod 26 form 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. Furthermore, one end of the third support rod 25 is rotatably connected to the second support cross bar 24, and the other end of the third support rod 25 is rotatably connected to the first support rod 22.

[0083] Furthermore, one end of the fourth support rod 26 contacts the ground to support the folding frame; 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.

[0084] It is also necessary to note that, please refer to Figure 10, further comprising: a fourth connecting member 28, the third support rod 25 and the first support rod 22 are connected to the fourth connecting member 28; specifically, the fourth connecting member 28 comprises: a foot pad 281, a third plywood 282 and a fourth plywood 283; the third plywood 282 and the fourth plywood 283 are L-shaped, and the two ends of the third plywood 282 are rotatably connected to the foot pad 281 and the first support rod 22 respectively; specifically, there are two third plywood 282, and the two third plywood 282 are arranged opposite to each other. The end of a support rod 22 away from the first connecting member 12 is placed between the two third plywoods 282, and the rotating shaft sequentially passes through the third plywood 282, the first support rod 22, and the other third plywood 282. There are two fourth plywoods 283, which are arranged opposite each other. The end of the third support rod 25 away from the second support cross bar 24 is placed between the two fourth plywoods 283, and the rotating shaft sequentially passes through the fourth plywood 283, the third support rod 25, and the other fourth plywood 283. The foot pad 281 is used to support the folding bracket on the ground, and the two ends of the foot pad 281 are respectively placed between the two third plywoods 282 and between the two fourth plywoods 283.

[0085] During operation, when the column 10 switches from the first state to the second state, the end of the first support cross bar 21 connected to the first connecting member 12 moves upward, and at the same time, the end of the first support rod 22 close to the first connecting member 12 moves upward synchronously; so that the other ends of the first support cross bar 21 and the first support rod 22 rotate toward the column 10.

[0086] As the first support cross bar 21 rotates, the first support cross bar 21 presses down the second support cross bar 24, so that the first support cross bar 21 and the second support cross bar 24 are folded in half until the first support cross bar 21 and the second support cross bar 24 are in contact with each other; at the same time, the first support cross bar 21 drives the first rod body 231 to rotate downward, so that the first rod body 231 and the second rod body 232 are folded in half.

[0087] During the folding process of the second supporting cross bar 24 and the first supporting cross bar 21 , the second supporting cross bar 24 drives the third supporting bar 25 to rotate toward the first supporting bar 22 .

[0088] According to some embodiments of the present application, referring to Figure 3The support frames 20 are symmetrically arranged on both sides of the column 10. The connection method between the two support frames 20 and the column 10 is the same and will not be repeated 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 extended), the support frames 20 on both sides of the column 10 are folded simultaneously.

[0089] According to some embodiments of the present application, referring to Figure 7 as well as Figure 11 The telescopic rod body 11 includes: an outer tube 111, an inner tube 112 and a folding frame. The outer tube 111 is sleeved on the inner tube 112. The inner tube 112 and the outer tube 111 are arranged to move relative to each other. The two ends of the first elastic member are respectively placed on the side of the inner tube away from the end of the outer tube and the side of the outer tube away from the end of the inner tube. The first elastic member is used to reset the telescopic rod body.

[0090] When the inner tube extends out of the outer tube, the first elastic member is in a stretched state.

[0091] When the inner tube 112 extends out of the outer tube 111, the folding frame is in a stretched state. The folding frame is a spring or a rubber band.

[0092] The outer tube 111 is slidably mounted on the inner tube 112, the outer tube 111 is connected to the first connecting member 12, and the inner tube 112 is connected to the second connecting member 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 connecting member 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 connecting member 13.

[0093] The folding frame is an elastic object such as a spring or a rubber band, and its two ends are respectively connected to the inner tube 112 and the outer tube 111. The two ends of the folding frame are respectively the end of the outer tube 111 away from the inner tube 112 and the end of the inner tube 112 away from the outer tube 111. In other embodiments, one end of the folding frame is connected to the outer tube 111 and the other end is connected to the second connecting member 13, or one end of the folding frame is connected to the inner tube 112 and the other end is connected to the first connecting member 12.

[0094] When the inner tube 112 extends out of the outer tube 111, the folding stand is in a second state, in which the folding stand is stretched to store elastic force. To unfold the folding stand, the user simply presses the telescopic rod 11, and the inner tube 112 and outer tube 111 move toward each other under the action of the elastic force. The folding stand allows the folding stand to unfold automatically.

[0095] According to some embodiments of the present application, referring to Figure 4 、 Figure 6 as well as Figure 7 The column 10 further includes a handle 14 , which is placed on the first connecting member 12 .

[0096] The handle 14 is placed on the column 10 to facilitate the user to operate the folding bracket; specifically, the handle 14 is a vertically arranged annular handle 14, and the handle 14 is placed on a side of the second clamping plate 122 away from the first clamping plate 121.

[0097] According to some embodiments of the present application, referring to Figure 4 、 Figure 6 as well as Figure 7 , the column 10 further includes: a placement protrusion 15;

[0098] The object placement protrusion 15 is placed on the first connecting member 12 . A plurality of through holes 151 are provided on the object placement protrusion 15 . The through holes 151 are used to accommodate objects.

[0099] The storage protrusion 15 is placed on the column 10 to facilitate the user to hang objects on the folding bracket. Specifically, the storage protrusion 15 is a protrusion protruding from the column 10 and is placed on the side of the second clamping plate 122 away from the first clamping plate 121. The storage protrusion 15 is provided with the through hole 151, which passes through the storage protrusion 15 and is vertically provided on the storage protrusion 15 for hanging objects.

[0100] See also Figures 1 to 11 , this embodiment provides a camping bed, comprising: any one of the embodiments of the folding bracket and a connecting frame body 30;

[0101] There are two folding brackets, and the two folding brackets are symmetrically arranged. The connecting frame is placed between the two folding brackets, and the two ends of the connecting frame 30 are respectively connected to one folding bracket.

[0102] 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 frames by shrinking or folding, so as to achieve the purpose of folding the camping bed.

[0103] In other embodiments, a camping bed further includes: a bed cloth; the length of the bed cloth is adapted to the length of the folding bracket in the first state, and the width of the bed cloth is adapted to the length of the connecting frame when unfolded; further, the opposite sides of the bed cloth are mounted on the first supporting cross bar 21 and the second supporting cross bar 24; the bed cloth can be folded accordingly when folded.

[0104] According to some embodiments of the present application, referring to Figure 7 and Figure 8 , the connecting frame 30 is a folding frame or a telescopic frame.

[0105] In some embodiments, the telescopic bracket is a telescopic rod. When folding is required, the distance between the two folding brackets arranged opposite to each other can be reduced by compressing the telescopic rod.

[0106] 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, wherein the first folding rod 31 and the second folding rod 32 are rotatably connected at their middle portions to form an X-shape, and the third folding rod and the fourth folding rod are also rotatably connected at their middle portions to form an X-shape; 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, and 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. Furthermore, the first folding rod 31 and the third folding rod are in the same plane, and the second folding rod 32 and the fourth folding rod are in the same plane; when folding is required, the first folding rod 31 and the third folding rod are close to each other, and the second folding rod 32 and the fourth folding rod are close to each other.

[0107] In other embodiments, a camping bed resetting mechanism includes: the folding bracket, a first folding rod 31 , a second folding rod 32 , and an elastic unit 33 ;

[0108] 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;

[0109] 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;

[0110] Two ends of the elastic unit 33 are respectively placed on one side of the first connecting member 12 and one side of the second connecting member 13 . The elastic unit 33 is used to reset the folding bracket.

[0111] Specifically, the first folding rod 31 and the second folding rod 32 can be rotated to form an X-shape, that is, the middle portion of the first folding rod 31 is rotatably connected to the middle portion of the second folding rod 32. 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.

[0112] One end of the elastic unit 33 is connected to the second connector 13, and the other end is connected to the first folding rod 31. To fold, the user pulls upward on the first connector 12, raising the first folding rod 31 while simultaneously storing elastic force in the elastic unit 33. To unfold, the elastic unit 33 releases the force, pulling downward on the end of the first folding rod 31 near the folding bracket 33. This causes the first folding rod 31 to move downward, simultaneously deploying the folding bracket through a coordinated action.

[0113] One end of the telescopic member is rotatably connected to the second connecting member 13 , the other end of the telescopic member is rotatably connected to the first folding rod, and both ends of the second elastic member are respectively connected to both ends of the lifting and retracting member.

[0114] The telescopic member is a tube body that is sleeved on each other, and the second elastic member is a spring, a rubber band, a cylinder or a hydraulic rod. Preferably, the second elastic member is a spring.
