Description

[0001] This application is a divisional application of the invention application titled "Folding Bed" with an application date of January 26, 2018 and an application number of 201810077000.X.

[0002] Technical Field

[0003] The invention relates to a folding bed. Background Art

[0004] There are various structures of children's beds in the prior art. Compared with the traditional wooden bed structure, folding beds are widely used because they can be folded to reduce the volume. However, most of the folding beds are relatively large in size after folding, and the structure is not compact enough, and still occupy a large space and are inconvenient for users to store and carry. Some folding beds are also very flat after folding, such as the folding bed disclosed in Chinese patent CN203693020U, in which the relatively folded parts of the folding bed are connected by rotation, and the relative locking between the parts is achieved by setting a locking mechanism in the rotating joint so that the folding bed is locked in the open state, which causes the folding bed to have more parts and higher production costs. Summary of the invention

[0005] The purpose of the present invention is to provide a folding bed with a novel structure.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a folding bed, comprising a support base and an upper frame assembly arranged on the support base, the upper frame assembly comprising a first frame and a second frame, the first frame comprising a first enclosure rod, the second enclosure rod comprising a second enclosure rod, a rod cavity of the first enclosure rod being provided with a sliding rod sliding along a length extension direction thereof, a connecting rod being fixedly provided on the second enclosure rod, the connecting rod being pivotally connected to the sliding rod through a rotating shaft, the upper frame assembly has two working states, when the upper frame assembly is in the first working state, the first enclosure rod and the second enclosure rod on the same side extend along the same length direction, the sliding rod, the rotating shaft and the connecting rod are all located in the rod cavity of the first enclosure rod; when the upper frame assembly is in the second working state, the rotating shaft is located outside the rod cavity of the first enclosure rod, one of the first enclosure rod and the second enclosure rod is flipped downward relative to the other, and an angle is formed between the first enclosure rod and the second enclosure rod.

[0007] In some embodiments, the sliding rod is provided with a guide groove extending along the length direction thereof, and a limit pin is fixed on the first surrounding rod, and the limit pin is inserted into the guide groove in a relatively slidable manner.

[0008] In some embodiments, a reset spring is disposed in the rod cavity of the first surrounding rod to provide the elastic force required for the sliding rod to slide back into the rod cavity of the first surrounding rod. One end of the reset spring abuts against one side wall of the limiting groove, and the other end thereof abuts against the limiting pin.

[0009] In some embodiments, the support base includes two support legs respectively disposed on the left and right sides. The first surrounding rod and the second surrounding rod both have two sets respectively disposed on the left and right sides. The top of the support leg is connected to one of the first surrounding rod and the second surrounding rod.

[0010] In some embodiments, the top of the support leg is connected to the first surrounding rod. When the upper surrounding frame assembly is in the second working state, the second surrounding rod rotates downward relative to the first surrounding rod and forms an angle with the first surrounding rod.

[0011] In some embodiments, a locking structure is provided between the support leg and the second surrounding rod to lock the upper surrounding frame assembly in the second working state. The locking structure includes a limiting head disposed on the support leg, and a clamping groove is formed on the limiting head. When the second surrounding rod rotates downward relative to the first surrounding rod, the second surrounding rod is clamped in the clamping groove.

[0012] In some embodiments, the top of the support leg is rotatably connected to the first surrounding rod through a surrounding frame connecting member. The surrounding frame connecting member has a sleeve portion, and the sleeve portion is rotatably sleeved on the first surrounding rod around the axis of the first surrounding rod.

[0013] In some embodiments, a limiting groove extending in the circumferential direction is formed on the sleeve portion, and the limiting pin can be inserted into the limiting groove in a relatively slidable fit manner.

[0014] In some embodiments, the support leg includes a column and a bottom rod. The column includes an upper leg and a lower leg that are telescopically connected to be relatively slidable in the vertical direction. The bottom rod extends forward and / or backward from the bottom of the lower leg. The upper surrounding frame assembly is disposed at the tops of the two upper legs on both sides.

[0015] In some embodiments, the support base further includes a cross brace assembly detachably connected between the two support legs on both sides. When the folding bed is in the opened state, the upper surrounding frame assembly and the cross brace assembly are supported between the two support legs on both sides; when the folding bed is in the folded state, the cross brace assembly is detached from between the two support legs on both sides.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: When using the folding bed of the present invention, pull the second surrounding rod outwards relative to the first surrounding rod, and then drive one of the first surrounding rod and the second surrounding rod to rotate, so that the height of the first surrounding frame or the second surrounding frame can be reduced, which is convenient for adults to take care of infants and young children on the folding bed.

[0030] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figure 1 、 Figure 3 The folding bed shown, which includes a support seat and an upper enclosure assembly 200 provided on the upper part of the support seat. The support seat includes two support legs 100 respectively arranged on the left and right sides, and a cross brace assembly 300 detachably connected between the two support legs 100 on both sides. The cross brace assembly 300 is located below the upper enclosure assembly 200. Among them, the upper enclosure assembly 200 at least includes two upper enclosure rods respectively arranged on the left and right sides, and these two upper enclosure rods each extend along the front-rear direction; on each side of the folding bed, the top of the support leg 100 is rotatably connected to the upper enclosure rod around the axis of the upper enclosure rod.

[0032] This folding bed has an open state and a folded state. When the folding bed is in the open state, as shown in Figure 1 、 Figure 3 shown, the support legs 100 on both sides stand on the ground, and the upper enclosure assembly 200 and the cross brace assembly 300 support each other up and down between the support legs 100 on both sides; when the folding bed is in the folded state, as shown in Figure 4 、 Figure 5 shown, the cross brace assembly 300 is detached from between the two support legs 100, and the support legs 100 on both sides respectively rotate towards each other around the upper enclosure rod on the corresponding side and are folded on the same side of the upper enclosure assembly 200, presenting a flat structure.

[0033] Specifically, see Figures 1 to 5As shown, the support legs 100 on each side each include a column 1 extending in the vertical direction and a bottom rod 2 fixed to the bottom of the column 1 and used for supporting on the ground. The column 1 includes an upper leg 11 and a lower leg 12 that are slidably and telescopically connected relative to each other in the vertical direction. The bottom rod 2 extends forward and / or backward from the bottom of the lower leg 12. In this embodiment, the bottom rod 2 extends from the bottom of the lower leg 12 in the front-rear direction toward one side, such that an L shape is formed between the bottom rod 2 and the column 1. The bottom rod 2 includes a first bottom rod 21 and a second bottom rod 22 that are relatively telescopically arranged in the front-rear direction, wherein the end of the first bottom rod 21 is fixedly connected to the bottom end of the lower leg 12, or the first bottom rod 21 and the lower leg 12 are integrally provided.

[0034] See Figure 1 , Figure 3 As shown, a cross brace assembly 300 is provided between the columns 1 on both sides, here between the lower parts of the upper legs 11 on both sides. The cross brace assembly 300 here is a lower frame assembly, and the lower frame assembly 300 can be used as an auxiliary support for the bed board of the folding bed. The lower frame assembly includes a U-shaped lower frame body 8 and a support frame 9 that is enclosed in a closed frame shape in the circumferential direction. The lower frame body 8 has lower perimeter bars 81 provided on the left and right sides respectively and a lower side bar 82 connected between one ends of the two lower perimeter bars 81. The support frame 9 is fixedly provided between the two lower perimeter bars 81. The other ends of the two lower perimeter bars 81 form insertion joints 81a to be detachably connected to the upper legs 11 on both sides respectively.

[0035] See Figure 1 As shown, insertion bushings 11a are provided on the upper legs 11 of the column 1, and the insertion bushings 11a on the upper legs 11 on both sides are arranged oppositely; through the mating of the two insertion joints 81a on the two lower perimeter bars 81 in the lower frame assembly with the two insertion bushings 11a, the plug-in connection between the two is realized.

[0036] See Figures 1 to 5 As shown, the upper frame assembly 200 includes a first frame 4 and a second frame 5 that are axially enclosed to form a frame. Here, both the first frame 4 and the second frame 5 are U-shaped. The first frame 4 includes two first perimeter bars 41 provided on the left and right sides respectively and a first side bar 42 connected between the two first perimeter bars 41; the second frame 5 includes two second perimeter bars 51 provided on the left and right sides respectively and a second side bar 52 connected between the two second perimeter bars 51. The first perimeter bar 41 and the second perimeter bar 51 on the same side are connected to form an upper perimeter bar, and the top of the support leg 100 is connected to one of the first upper perimeter bar 41 and the second perimeter bar 51.

[0037] See Figure 1 , Figure 2As shown, a surrounding frame connecting member 3 is fixedly provided at the top of each side column 1. The surrounding frame connecting member 3 is sleeved on the upper surrounding rod rotatably around the axis of the upper surrounding rod. In this embodiment, the surrounding frame connecting member 3 is connected to the first surrounding rod 41. Specifically, the surrounding frame connecting member 3 has a sleeve portion 31 sleeved on the upper surrounding rod, and the sleeve portion 31 is sleeved on the first surrounding rod 41 rotatably around the axis of the first surrounding rod 41. As Figure 2 shown, a circumferentially extending limiting groove 33 is further formed in the sleeve portion 31, and a limiting pin 6 is fixedly arranged on the first surrounding rod 41. The limiting pin 6 can be inserted into the limiting groove 33 in a relatively sliding fit manner to provide guidance and limitation for the relative rotation of the two when the support leg 100 rotates around the upper surrounding rod.

[0038] When the folding bed is in the open state, the limiting pin 6 abuts against one end wall of the limiting groove 33. By connecting the lower surrounding frame assembly 300 between the two side columns 1, the relative fixation between the first surrounding rod 41 and the surrounding frame connecting member 3 can be achieved, so that the upper surrounding frame assembly 200 is relatively fixed to the two support legs 100, and the folding bed is stably in the open state; when the lower surrounding frame assembly 300 is detached from between the two side columns 1 and the two support legs 100 are rotated respectively around the axis of the corresponding side first surrounding rod 41, the limiting pin 6 slides relatively in the limiting groove 33 until it abuts against the other end wall of the limiting groove 33, and the support leg 100 is folded with the upper surrounding frame assembly 200 to realize the folding of the folding bed.

[0039] See Figures 6 to 11 shown, in the upper surrounding frame assembly 200 of this embodiment, a sliding rod 43 sliding along the length extension direction thereof is arranged in the rod cavity of the first surrounding rod 41. A connecting rod 53 is fixedly arranged on the second surrounding rod 51, and the end of the connecting rod 53 is pivotally connected to the end of the sliding rod 43 through a rotating shaft 7. This enables the upper surrounding frame assembly 200 to have two working states when the folding bed is in the open state: when the upper surrounding frame assembly 200 is in the first working state, the first surrounding rod 41 and the second surrounding rod 51 on the same side extend along the same length direction, and the sliding rod 43, the rotating shaft 7 and the connecting rod 53 are all received in the rod cavity of the first surrounding rod 41, as Figure 1 , Figure 2 , Figure 6 shown; when the upper surrounding frame assembly 200 is in the second working state, at least part of the sliding rod 43 extends out of the first surrounding rod 41, so that the connecting rod 53 and the rotating shaft 7 are both outside the rod cavity of the first surrounding rod 41, as Figure 7 , Figure 8 shown. At this time, the second surrounding rod 51 can be turned downward relative to the first surrounding rod 41 to form an angle with the first surrounding rod 41, as Figures 9 to 11 shown. The main advantage of such a setting is that the height at the second surrounding frame 5 can be reduced, which is convenient for adults to take care of the infants and young children on the folding bed.

[0040] In this embodiment, on each side of the folding bed, a locking structure is further provided between the support leg 100 and the second surrounding rod 51, which cooperate to lock the upper surrounding frame assembly 200 in the second working state. Here, the locking structure is provided between the surrounding frame connecting member 3 and the second surrounding rod 51. Specifically, referring to Figures 1 to 3 、 Figures 6 to 11 As shown, the surrounding frame connecting member 3 on each side further has a limiting head 32, which extends from the lower part of the sleeve portion 31 in a direction away from the first surrounding rod 41. An upwardly opening card slot (not shown in the figure) is provided on the limiting head 32. When the second surrounding rod 51 rotates downward relative to the first surrounding rod 41 and is correspondingly clamped in the above card slot, the upper surrounding frame assembly 200 is converted and locked in the above second working state.

[0041] In this embodiment, referring to Figure 6 、 Figure 11 As shown, in each side of the upper surrounding frame assembly 200, a return spring 44 for providing the elastic force required for the sliding rod 43 to slide back in the rod cavity of the first surrounding rod 41 is further provided in the rod cavity of the first surrounding rod 41, so that when there is no external force, the first surrounding rod 41 and the second surrounding rod 51 on the same side are connected and extend along the same length direction, so that when the upper surrounding frame assembly 200 is in the first working state, and after unlocking the second working state, the second surrounding rod 51 can automatically rotate and reset relative to the first surrounding rod 41. Here, a guiding groove 43a extending along the length direction of the sliding rod 43 is provided on the sliding rod 43, and a guiding pin is fixed on the first surrounding rod 41. Here, the limiting pin 6 is used as the guiding pin, and the limiting pin 6 is relatively slidably inserted into the above guiding groove 43a. One end of the return spring 44 abuts against one side wall of the limiting groove 43a and the other end thereof abuts against the limiting pin 6.

[0042] In summary, the folding bed of the present invention has few rod members and a simple structure. It has good stability in the unfolded state. The second surrounding frame 5 of the upper surrounding frame assembly 200 can rotate relative to the first surrounding frame 4 to reduce the height, which is convenient for the user to immediately look after the infants in the folding bed; when it needs to be folded, only the lower surrounding frame assembly 300 as the cross brace assembly needs to be disassembled, and then the support legs 100 on both sides can be turned towards each other relative to the upper surrounding frame assembly 200 to complete the folding. The folding operation is very simple and the folded structure is very flat, which provides great convenience for the user's daily storage and carrying, etc.

[0043] The above embodiments are only for explaining the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
