Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, and more specifically it relates to a single bed with a folding structure. Background Technology

[0002] As people's lifestyles become more diverse, the demand for beds is no longer limited to traditional fixed home use. For example, in scenarios such as outdoor camping, temporary guest rooms, short-term rentals, or student dormitories, users urgently need a bed that can provide stable and comfortable sleep support, and can also be quickly folded up to reduce space occupation and is easy to move when not in use.

[0003] While existing folding beds possess certain folding functions, they still have many shortcomings: some products remain irregular in shape after folding, with limited volume reduction, making them difficult to fit into a car trunk or narrow storage corner; others are complex to operate during unfolding and folding, requiring tools or multiple people to assist, resulting in a poor user experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a single bed with a folding structure, which has the advantages of realizing quick and simple unfolding and folding operations, and its volume in the folded state is convenient for transportation and storage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A single bed with a folding structure includes a bed frame body, supporting beams and supporting legs. The bed frame body is formed by a first frame and a second frame pivotally connected by a hinge assembly. The opposing inner edges of the first frame and the second frame are provided with guide grooves, and the ends of multiple supporting beams are slidably embedded in the guide grooves. The bottom of both the first frame and the second frame is provided with a receiving cavity. The top of the support leg is rotatably received in the receiving cavity via a pivot. A strip-shaped guide hole is provided through the outer wall of the receiving cavity. A linkage rod is hinged to the support leg. A roller is provided at the free end of the linkage rod. The roller is placed in the strip-shaped guide hole and can slide along its length. The roller axle is provided with a locking screw, which is threadedly engaged with the roller axle, and its end can abut against the outer wall of the strip-shaped guide hole.

[0006] The advantages of this design are at least as follows: This invention achieves rapid unfolding and folding of the bed frame through the cooperation of a sliding support beam and guide groove, and a sliding linkage mechanism consisting of support legs, linkage rods, rollers, and strip guide holes. When folded, the support beam can be centrally stored, and the support legs can be rotated and retracted into the receiving cavity. Finally, the two frames are folded in half, greatly reducing the storage volume and facilitating transportation and storage. When unfolded, the support legs are lowered and locked by locking screws, forming a stable triangular support structure. The operation is simple and quick, and can be completed by a single person.

[0007] The present invention is further configured such that: a plurality of locking recesses for positioning the supporting beam are spaced apart on the groove wall of the guide groove.

[0008] The advantages of this scheme are at least as follows: by setting the locking recess, the support beam can be reliably locked when it slides to the designated position, preventing it from sliding due to force or vibration during use of the bed, ensuring the uniformity of the distribution of the support beam and the flatness and stability of the bed surface, and improving the comfort and safety of use.

[0009] The present invention is further configured such that: the opposite ends of the first frame and the second frame are provided with limit holes, and are equipped with limit pins that can be inserted into the limit holes.

[0010] The advantages of this solution are at least as follows: when folding and storing, pushing all the support beams to one side and inserting the limiting pins can effectively prevent the support beams from accidentally sliding out of the guide groove during handling or movement, ensuring the neatness and stability of the folded state and avoiding the scattering of parts.

[0011] The present invention is further configured such that auxiliary support rods are screwed onto the bottom surfaces of the first frame and the second frame respectively.

[0012] The advantages of this scheme are at least as follows: by setting an auxiliary support rod below the hinge in the middle of the bed frame, the load of the bed can be shared with the support legs at the four corners, which significantly reduces the bending moment and shear force borne by the hinge assembly, prevents it from deforming or being damaged due to long-term overload, and extends the overall service life of the bed.

[0013] The present invention is further configured such that: the first frame and the second frame have hidden grooves at their opposite ends for receiving the auxiliary support rods.

[0014] The advantages of this solution are at least as follows: the hidden slots allow the auxiliary support rods to be completely stored inside the bed frame when not in use, achieving integrated storage of components, avoiding the risk of losing extra parts, and making the folded bed more regular, which is convenient for transportation and storage.

[0015] The present invention is further configured such that: a spring groove is provided on the side of the accommodating cavity, a tension spring is installed in the spring groove, a movable baffle is connected to the outer end of the tension spring, and a fastening piece for pressing the support foot is pivotally connected to the movable baffle.

[0016] The advantages of this solution are at least as follows: the elastic force of the tension spring drives the fastening plate to automatically press the folded support foot, which can effectively prevent the support foot from falling out of the storage cavity during the folded state and transportation process, thus improving the reliability and convenience of storage, without the need for additional operation to bind or fix it.

[0017] The present invention is further configured such that: the bottom of the first frame is provided with a plurality of male connectors, and the bottom of the second frame is provided with a plurality of female connectors that engage with the male connectors.

[0018] The advantages of this solution are at least as follows: by using the snap-fit ​​between the male connector and the female connector, the first frame and the second frame can be securely locked together after the bed is fully folded, preventing them from unfolding on their own during transport, ensuring the stability and integrity of the folded state, and making it more convenient and effortless to carry.

[0019] 1. High space utilization: Through multiple folding methods such as the convergence of supporting beams, the concealment of support legs, and the folding of the frame, the bed is transformed from a three-dimensional use state into a compact plate structure, which greatly reduces the storage volume and makes it easy to put into narrow storage spaces or vehicle trunks, making it extremely convenient to move and transport.

[0020] 2. Simple and quick operation: The entire unfolding and folding process requires no tools and can be completed through simple sliding, rotating, pinning and buckling operations. The design is ergonomic, and even users with less strength can complete all the steps independently and easily.

[0021] 3. Stable and reliable structure: In the unfolded state, the support legs form a stable triangular support through a sliding linkage mechanism consisting of a linkage rod, rollers, and strip guide holes, combined with the fastening of the locking screw; the support beam is positioned by the locking recess, effectively preventing shaking and abnormal noise during use, ensuring the comfort and safety of sleep.

[0022] 4. Integrated Component Design: All auxiliary components, such as limit pins and auxiliary support rods, have their dedicated storage locations (limiting holes, hidden slots). The support legs have snap-fit ​​plates for automatic locking, and the bed frame is locked in place via male and female connectors after folding. This design ensures that all components are integrated with the main body of the bed, effectively preventing the loss of small parts during disassembly, assembly, and transportation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] A single bed with a folding structure, such as Figure 1 As shown, the bed frame includes a main body 1, supporting beams 2 and supporting legs 3. The main body 1 is formed by pivotally connecting a first frame 101 and a second frame 102 through a hinge assembly. The inner edges of the first frame 101 and the second frame 102 are provided with guide grooves 4, and the ends of multiple supporting beams 2 are slidably embedded in the guide grooves 4. Both the bottom of the first frame 101 and the second frame 102 have accommodating cavities 5 (see reference). Figure 2 The top of the support leg 3 is rotatably housed in the receiving cavity 5 via a pivot, and a strip-shaped guide hole 6 is provided through the outer wall of the receiving cavity 5; a linkage rod 7 is hinged to the support leg 3, and a roller 8 is provided at the free end of the linkage rod 7 (see reference). Figure 3 Roller 8 is placed inside the strip guide hole 6 and can slide along its length. A locking screw 9 is provided on the axle of roller 8, which is threaded into the axle of roller 8, and its end can abut against the outer wall of the strip-shaped guide hole 6. This invention achieves rapid unfolding and folding of the bed frame through the cooperation of the sliding support beam 2 and the guide groove 4, and the sliding linkage mechanism composed of the support leg 3, the linkage rod 7, the roller 8, and the strip-shaped guide hole 6. When folded, the support beam 2 can be neatly stored, and the support leg 3 can be rotated and stored in the receiving cavity 5. Finally, the two frames are folded in half, greatly reducing the storage volume and facilitating transportation and storage. When unfolded, the support leg 3 is lowered and locked by the locking screw 9, forming a stable triangular support structure. The operation is simple and quick, and can be completed by a single person.

[0027] like Figure 5 As shown, the guide groove 4 has multiple locking recesses 10 spaced apart on its groove wall for positioning the support beam 2. By setting the locking recesses 10, the support beam 2 can be reliably locked when it slides to the designated position, preventing it from sliding due to force or vibration during use of the bed. This ensures the uniformity of the distribution of the support beam 2 and the flatness and stability of the bed surface, improving user comfort and safety.

[0028] like Figure 5 As shown, limit holes 11 are provided at the opposing ends of the first frame 101 and the second frame 102 (see reference). Figure 1 It is equipped with a limiting pin 12 that can be inserted into the limiting hole 11. When folding and storing, after pushing all the supporting beams 2 to one side, inserting the limiting pin 12 can effectively prevent the supporting beams 2 from accidentally sliding out of the guide groove 4 during handling or movement, ensuring the neatness and stability of the folded state and avoiding the scattering of parts.

[0029] like Figure 1 As shown, auxiliary support rods 13 are screwed onto the bottom surfaces of the first frame 101 and the second frame 102 respectively. By setting the auxiliary support rods 13 below the hinge in the middle of the bed frame, they can share the load of the bed with the support legs 3 at the four corners, significantly reducing the bending moment and shear force borne by the hinge assembly, preventing it from deforming or being damaged due to long-term overload, and extending the overall service life of the bed.

[0030] like Figure 6 As shown, the first frame 101 and the second frame 102 have hidden slots 14 at their opposite ends for storing the auxiliary support rods 13. The hidden slots 14 allow the auxiliary support rods 13 to be completely stored inside the bed frame when not in use, achieving integrated storage of components, avoiding the risk of losing extra parts, and making the folded bed more regular, convenient for transportation and storage.

[0031] like Figure 4As shown, a spring groove 15 is provided on the side of the accommodating cavity 5, and a tension spring 16 is installed in the spring groove 15. A movable baffle 17 is connected to the outer end of the tension spring 16, and a fastening piece 18 for pressing the support leg 3 is pivotally connected to the movable baffle 17. The elastic force of the tension spring 16 drives the fastening piece 18 to automatically press the folded support leg 3, which can effectively prevent the support leg 3 from falling out of the accommodating cavity 5 on its own in the folded state and during transportation, improving the reliability and convenience of storage, without the need for additional operation of binding or fixing.

[0032] like Figure 2 As shown, the bottom of the first frame 101 is provided with multiple male connectors 19, and the bottom of the second frame 102 is provided with multiple female connectors 20 that engage with the male connectors 19. Through the snap-fit ​​between the male connectors 19 and the female connectors 20, the first frame 101 and the second frame 102 can be securely locked together after the bed is fully folded, preventing it from unfolding on its own during transportation, ensuring the stability and integrity of the folded state, and making it more convenient and effortless to carry.

[0033] The working process and beneficial effects of this utility model are as follows: When folding and storing, firstly, all the supporting beams 2 are slid along the guide groove 4 to one side of the first frame 101 and arranged tightly. Then, the limiting pins 12 are inserted into the limiting holes 11 to prevent the supporting beams 2 from falling off. Next, the locking screws 9 on the axles of each roller 8 are loosened, and the support feet 3 are rotated toward the receiving cavity 5 until they are completely stored in the receiving cavity 5. They are then fixed by the automatic pressing action of the fastening piece 18 under the action of the tension spring 16. After that, the auxiliary support rod 13 is unscrewed and placed in the corresponding hidden groove 14. Finally, the second frame 102 is flipped and folded toward the first frame 101, and the entire bed is locked in the folded state by the engagement of the male connector 19 and the female connector 20.

[0034] When it needs to be unfolded for use, the operation process is the reverse: unfold the main body 1 of the bed frame, slide the support beam 2 evenly and position it through the locking recess 10, install and tighten the auxiliary support rod 13, release and rotate the support leg 3 to the vertical position, use the linkage rod 7 and roller 8 mechanism to unfold it into place, and finally tighten the locking screw 9 to complete the stable support of the bed.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
