Description

Technical Field

[0001] This utility model relates to a bread bed, specifically a bread bed that can be automatically folded up. Background Technology

[0002] A bread-shaped bed is a type of bed designed in the shape of a loaf of bread. Inspired by French pastries, it uses soft, plush cushions and resilient foam to mimic the fluffy texture of bread, aiming to provide a comfortable support experience. A bread-shaped bed requires a corresponding upright structure to support the overall structure and ensure the bed's stability.

[0003] Existing bread-making beds have a complex structure and unreasonable design, exhibiting the following problems: 1. Their structure is typically a rectangular rod, which cannot adequately support the armrests facing different directions at both ends. Over time, the armrests tend to sag, leading to overall structural loosening and deformation. 2. Both closing and locking require considerable force, and some poorly designed operations require two people, resulting in a poor user experience. 3. Closing requires manipulating multiple structures on the bed's uprights, making the process cumbersome and difficult to complete in one step. It is difficult for one person to achieve the folding function, and both folding and unfolding require significant force, resulting in a poor user experience. Therefore, the inventor has improved the structure of the bread-making bed. Utility Model Content

A gear component is installed on the base, which rotates with the movement of the rack component. A connecting rod is installed on the gear component, which flips as it rotates. In use, the lifting seat is lifted, which drives multiple matching teeth on the rotating seat to rotate downward, thereby causing the connecting rod to fold down synchronously and become vertical. By folding the column synchronously, the entire bread bed frame is folded down. The entire operation is completed in one step. The operation steps are simple and can be easily completed by one person, saving time and effort. It can also easily unfold the entire bread bed frame, enabling rapid unfolding and folding, and providing a good user experience. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0022] Please see Figures 1 to 2 One embodiment of this utility model is a bread bed that can be automatically folded up. The bread bed includes four sets of L-shaped bed column structures 1. Adjacent sets of bed column structures 1 are connected by a handrail locking structure 2, and the four sets of bed column structures 1 are connected by a column folding structure 3. Each set of bed column structures 1 is provided with an assembly buckle structure 4, and the column folding structure 3 is provided with a bed tightening structure 5.

[0023] Please see Figures 3 to 8The bed frame column structure 1 is L-shaped and includes a face shell 11 and a load-bearing component 12 fixed to the face shell 11. The end of the load-bearing component 12 away from the face shell 11 is provided with a reinforcing rib 13 and a load-bearing seat 15 for supporting the load-bearing component 12. The load-bearing component 12 is also provided with rod fixing components 14. There are two reinforcing ribs 13 and two rod fixing components 14, and the two reinforcing ribs 13 are arranged in parallel. The reinforcing ribs 13 ensure that the load-bearing component 12 will not deform under tensile force. The load-bearing component 12 includes double-sided support plates 121 and a reinforcing beam 122 fixed integrally with the double-sided support plates 121. Both ends of the reinforcing beam 122 have strip grooves 123. Two parallel positioning inserts are fixed to the bottom of the double-sided support plates 121. Each reinforcing rib 13 is fixedly connected to both ends of the double-sided support plate 121, and the two reinforcing ribs 13 are respectively connected to both ends of the reinforcing beam 122. In this embodiment, the reinforcing ribs 13 are made of aluminum alloy, which has the function of structural strength and stability. Therefore, the reinforcing ribs 13 can simultaneously support the double-sided support plate 121 and the reinforcing beam 122, playing a role in structural reinforcement, so that the bed column structure 1 as a whole has better stability and is not prone to deformation during use, so that the bed column structure 1 as a whole has better load-bearing performance. Side grooves 124 are provided in both strip grooves 123, and two rod fixing parts 14 are respectively fixed in the two side grooves 124. Two parallel positioning inserts are fixed at the bottom of the double-sided support plate 121. 125. Two reinforcing ribs 13 are respectively set in two strip grooves 123. Each of the two strip grooves 123 is provided with a side groove 124. Two rod fixing members 14 are respectively fixed in the two side grooves 124, and the orientation of the two rod fixing members 14 is perpendicular to each other. Both rod fixing members 14 are used to directly connect with the rods of the bread bed armrests, and the orientation of the rods of the two bread bed armrests is perpendicular to each other. The load-bearing seat 15 supports the bottom of the load-bearing member 12 to prevent the load-bearing member 12 from sagging due to excessive pressure. It ensures that the load-bearing member 12 and the armrest rods installed on the load-bearing member 12 will not sag after long-term use, making the overall structure of the bread bed more robust. The rod fixing member 14 includes a fixing shell 141 and a... The protruding cylinder 142 is fixed in place. The end of the protruding cylinder 142 away from the fixed shell 141 is a hollow cavity structure. The inner wall of the cavity is fixed with multiple limiting ribs 143. Correspondingly, the bar of the bread bed armrest is provided with a corresponding groove. The groove fits the limiting rib 143, so that the bar of the bread bed armrest remains fixed after being inserted into the cavity of the protruding cylinder 142, ensuring a better connection between the bar fixing member 14 and the bar of the bread bed armrest. The load-bearing base 15 includes a main support block 151 and extension pieces 152 fixed to both ends of the main support block 151. The main support block 151 and the extension pieces 152 at both ends are fixed with bar seats 153. The end of the main support block 151 away from the bar seat 153 is fixed with a reinforcing support 154.The upper end face of the pole seat 153 is provided with a pole mounting groove 1531, and a roller 16 is installed at the bottom of the pole seat 153. The portion of the reinforcing beam 122 located between the two positioning inserts 125 is inserted into the reinforcing support 154 and fixed to the reinforcing support 154. Therefore, the reinforcing support 154 can directly support the reinforcing beam 122, and the load-bearing seat 15 supports the bottom of the load-bearing component 12, so that the load-bearing component 12 can better support the handrail pole above it and will not deform due to the tension of the handrail pole, ensuring that it will not deform after long-term use and extending its service life. Both ends of the reinforcing support 154 are fixed with fixing plates 155, and the two positioning inserts 125 are respectively fixed to the two fixing plates 155.

[0024] Please see Figures 9 to 14 The handrail locking structure 2 includes a protective cover 21 and a locking mechanism 22 disposed inside the protective cover 21. The protective cover 21 includes a connecting handle 211 and two protective shells 212 fixed to the connecting handle 211. The two protective shells 212 are symmetrically disposed at both ends of the connecting handle 211, and each of the two protective shells 212 is provided with a receiving groove 2121. The two steering handles 225 are respectively disposed in the two receiving grooves 2121 at their close ends. The locking mechanism 22 includes a fixed base 221 and two sets of receiving angles 222 fixed to the fixed base 221. Each set of receiving angles 222 has two angles. A bridging plate 223 and a locking element 224 are disposed above the fixed base 221. There are two bridging plates 223 in total. Both bridging plates 223 are V-shaped, and the two bridging plates 223 are rotatably connected at their close ends by a shaft. This shaft is not shown in the attached drawings, but its structure is prior art. Figure 13As can be seen, the two bridging plates 223 are rotatably connected at their close ends. The two bridging plates 223 are respectively set on two sets of storage angles 222. The two bridging plates 223 are respectively set on their far ends, and are equipped with steering handles 225 that rotate synchronously. The locking member 224 is set between the two steering handles 225, and the locking member 224 includes a main support block 2241, extension strips 2242 respectively fixed to both ends of the main support block 2241, and a limiting plate 2243 fixed to the bottom of the main support block 2241. The main support block 2241 is set on the two bridging plates 222. Above the connecting plate 223, two extension strips 2242 are respectively connected to the two bridging plates 223, and gaps 22421 are provided through both extension strips 2242. After the two steering handles 225 are flipped to the horizontal position, they are respectively limited to the two ends of the locking member 224. The horizontal steering handles 225 can just enter the gaps 22421 and remain horizontal, i.e., locked. When the steering handles 225 are flipped 90°, they are in a vertical position, which can complete the folding of the bread bed armrests. At this time, the bread bed is in a folded storage state. By setting the extension strip 2242 and the gap 22421, the rotation range of the steering hand 225 is limited, allowing it to rotate only within a 90° range. This avoids excessive rotation that could cause structural damage and extends its service life. The steering hand 225 includes a base block 2251, a limiting hook 2252 set on the base block 2251, and a protruding block 2253 located on one side of the limiting hook 2252. When the base block 2251 is rotated to a horizontal state, it causes the limiting hook 2252 to extend into the gap 22421 and interact with the gap 22421. The inner wall of the steering handrail is contacted, thereby using the gap 22421 to limit the steering handrail 225 as a whole, keeping the steering handrail 225 in a horizontal state. At this time, the bread bed armrest is in a horizontal state. The two armrest connecting sleeves 23 are respectively fixed to the two ends of the steering handrail 225 that are far apart from each other. Specifically, the armrest connecting sleeves 23 are fixed to the two base blocks 2251. The ends of the two armrest connecting sleeves 23 that are far apart from each other are respectively used to connect to the two rods on the bread bed armrest, so that the two rods can be closed or locked by means of the protective cover 21 and the locking mechanism 22. Figure 12 and attached Figure 15The state shown is the locked state. In this state, the bread bed armrests remain horizontal and stable, supporting the bread bed. To fold the bread bed armrests, the two rods need to rotate 90°, causing the two armrest connecting sleeves 23 and the two base blocks 2251 to remain vertical. During this process, the two first tension springs 226 deform, and the two steering handles 225 separate from the locking element 224, thus unlocking the bread bed armrests and folding the bread bed. Locking is achieved by simply reversing the above steps. The overall operation is convenient, with few steps, saving time and effort. Only one person is needed to quickly fold and lock the bread bed armrests. For a better experience, each of the two steering handles 225 is equipped with a first tension spring 226 near the locking member 224. The two steering handles 225 are connected to two sets of storage angles 222 respectively through the two first tension springs 226. The two first tension springs 226 realize the folding and locking of the two steering handles 225 respectively. The first tension spring 226 includes a main spring 2261 and a flip spring 2262 and a positioning spring 2263 respectively set at both ends of the main spring 2261. The flip spring 2262 is connected to the base block 2251, and the positioning spring 2263 is connected to the storage angle 222. Two armrest connecting sleeves 23 are symmetrically arranged on the two protective covers 21. The two armrest connecting sleeves 23 are respectively fixed to the two steering handles 225 at the ends that are far apart from each other.

[0025] Please see Figures 15 to 20The column retractable structure 3 includes a base 31, which includes a bottom support 311. The bottom support 311 has multiple rotating grooves 312, and each rotating groove 312 has a first mounting groove 313 on both sides. The base 31 is a hollow cavity structure with openings at both ends. A rack component 32 is installed through the cavity from bottom to top, and the rack component 32 moves vertically within the cavity. A gear component 33 is installed on the base 31, rotating with the rack component 32. A connecting rod 34 is installed on the gear component 33, rotating and flipping with it. The rack component 32 includes a lifting seat 321, which has multiple sets of toothed grooves 322. The gear component 33 includes a rotating seat 331 and multiple gears arranged around the circumference of the rotating seat 331. The adapter teeth 332 and the rotating seat 331 are fixed on the connecting rod 34. The multiple adapter teeth 332 on the rotating seat 331 mesh with one set of tooth grooves 322. When the lifting seat 321 rises and falls, the meshing of the tooth grooves 322 with the adapter teeth 332 drives the rotating seat 331 to rotate on the base 31, thereby causing the gear part 33 to drive the connecting rod 34 to rotate at a certain angle. The rotation angle of the connecting rod 34 is between 0° and 90°. Each set of tooth grooves 322 is provided with multiple teeth at intervals and is arranged in a straight line along the vertical direction. Both the gear part 33 and the connecting rod 34 are provided with multiple sets, and multiple sets of gear parts 33 surround the outside of the rack part 32. The connecting rod 34 includes a rod sleeve 341 and a main rod body 342 fixed on the rod sleeve 341. The rod sleeve 341 is away from the main rod body. One end of 342 is a hollow cavity structure, and the end of the sleeve 341 away from the main rod 342 is inserted into the interior of the rotating seat 331 and fixedly connected to the rotating seat 331, so that the sleeve 341 can rotate synchronously with the rotating seat 331. In addition, a horizontally arranged shaft is installed in the first mounting groove 313 on both sides of the rotating groove 312. The shaft passes through the rotating seat 331 and the sleeve 341, allowing the rotating seat 331 to rotate freely. The end of the connecting rod 34 away from the base 31 is set on the synchronous folding column 35, and the connecting rod 34 is movably connected to the synchronous folding column 35. When the connecting rod 34 rotates on the base 31 with the gear part 33, the connecting rod 34 will pull the synchronous folding column 35 closer to or away from the base 31. When the uprights 35 are close to the base 31, the bread bed frame is folded up. When the uprights 35 are folded away from the base 31, the bread bed frame is unfolded. The structure of the folding uprights 35 is existing technology and is part of the bread bed, so it will not be described in detail here. In use, the lifting seat 321 is lifted upwards, causing the multiple adapter teeth 332 on the rotating seat 331 to rotate downwards, thereby causing the rod sleeve 341 and the main rod 342 to fold downwards synchronously and become vertical. The bread bed frame is folded up and down by folding the uprights 35. The whole operation is completed in one step. The operation steps are simple and can be easily completed by one person, saving time and effort. When unfolding, simply press the lifting seat 321 to move it downwards and drive the rotating seat 331 to rotate upwards.This allows the sleeve 341 and the main rod 342 to open upwards synchronously and reach a horizontal position, causing the base 31 parts to unfold synchronously, thus realizing the function of synchronous unfolding of the bed frame. Bread beds using this structure can easily unfold the entire bed frame, enabling rapid unfolding and folding, providing a good user experience.
