Description

[Technical field]

[0001] The present invention relates to an automatic lifting and lowering type folding bed, and more particularly to a folding bed that improves space efficiency when moved or not in use by the folding structure of a health functional bed, and can automatically perform lifting and lowering operations for folding. [Background technology]

[0002] 2. Description of the Related Art Recently, as interest in health has increased, functional bed products having various therapeutic functions, such as those for thermotherapy having a heating function, those for massage using massage tools, or those for physical therapy, have been released.

[0003] Such functional beds require a length equivalent to the height of an adult, so when the frame is manufactured, it is manufactured to a predetermined length and then transported to the consumer or to the sales floor.

[0004] However, conventional treatment beds have an integrated structure, which makes it difficult to store and move them due to the space they occupy during transportation or storage, and also causes inconveniences such as occupying room space even when the user is not using the bed.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0011] The present invention may be modified in various ways, and the scope of the present invention should not be construed as being limited to the following detailed examples, which are provided to more completely explain the present invention to those skilled in the art.

[0012] Therefore, the shapes of components shown in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same components may be denoted by the same reference symbols in the various drawings. In addition, detailed descriptions of the functions and configurations of known technologies that are deemed to be likely to unnecessarily obscure the gist of the present invention may be omitted.

[0013] First, an automatic lifting and lowering type folding bed structure according to an embodiment of the present invention will be described with reference to FIGS.

[0014] The folding bed according to this embodiment includes the basic components of a main body frame 10 having a predetermined height for supporting the upper body of a user, a leg frame 20 connected to one side of the main body frame 10 and supporting the lower body of the user, a plurality of folding legs 30 whose upper ends are connected to the leg frame 20 so as to be rotatably foldable, and an actuator 40 connected to the upper part of the folding legs 30 for driving the rotation of the folding legs 30.

[0015] At this time, a lift guide section 11 is provided vertically on one side of the main frame 10 to guide the lift of the leg frame 20, a first guide roller 21 is provided on the corresponding leg frame 20 to guide it along the lift guide section, sliding guide rails 12 are provided on both sides of the lower part of the main frame 10 to guide the horizontal sliding and folding operation of the leg frame 20, and a second guide roller 22 is provided on one end of the corresponding leg frame 20 to move along the sliding guide rails 12.

[0016] The first guide roller 21 is connected and supported by the leg frame 20 via a "⊂"-shaped support bracket 21a, and is rotatably connected to the support bracket 21a via a rotation shaft 21b.

[0017] The folding legs 30 are connected at their upper ends to each other by a connecting frame 32, and are configured to simultaneously fold around a pivot shaft driven by an actuator 40.

[0018] The effects of the operation of the automatic lifting and lowering type folding bed according to the present invention having the above-mentioned configuration will be described below.

[0019] The bed of the present invention can be used for various functions such as thermotherapy, massage, or physical therapy, and has a configuration in which a leg frame 20 supporting the lower body is connected to one side of a main body frame 10 supporting the upper body so as to be capable of ascending, descending, sliding, and folding.

[0020] Figures 1 to 7 show a state in which the leg frame 20 is raised to the same height as the main frame 10. In this state, when attempting to perform a folding operation for transporting or storing the bed, the leg frame 20 is first lowered.

[0021] That is, at this time, when the folding legs 30 are rotated and folded by the operation of the actuator 40, the leg frame 20 is gradually processed as shown in Figures 8 and 9. At this time, the first guide roller 21 arranged on one side is guided down by the lift guide part 11, so that the leg frame 20 can be lowered while maintaining a stable horizontal state.

[0022] In particular, during this lowering operation, since the four folding legs 30 are connected by the interconnecting frame 32 when the actuator 40 operates, it can be seen that the folding and rotating are performed simultaneously.

[0023] When the lowering operation is completed, the state shown in Figures 10 to 12 is reached. At this time, it can be seen that the second guide roller 22 arranged at the end of the leg frame 20 is seated on the sliding guide rail 12.

[0024] In this state, when the user applies force to pull the leg frame 20 into the main frame 10, the second guide rollers 22 are slidably guided along the sliding guide rails 12, causing the leg frame 20 to be pulled in, ultimately achieving the storage state as shown in Figures 13 to 15.

[0025] On the other hand, to use the bed, the leg frame 20 is pulled out from the main frame 10 in the reverse order to the above, and the actuator 40 is operated in this state, whereby the leg frame 20 is gradually lifted and returned to its original state.

[0026] Therefore, the folding bed according to the present invention has an effect that the lowering operation for sliding and folding the leg frame can be performed automatically, improving convenience of use and allowing easy transportation and storage.

[0027] 16 is a diagram showing the configuration according to another embodiment of the present invention, in which a buffer pad 13 is provided at the tip of a sliding guide rail 12 formed on a main frame 10 to absorb the impact of a first guide roller 21 when a leg frame 20 descends. The buffer pad 13 is elastically supported at its lower part by a buffer spring 14, and the buffer spring 14 is provided in a pad groove 14a formed in the sliding guide rail 12.

[0028] In addition, the sliding guide rail 12 is coated with a protective layer 15 to reduce the impact of the second guide roller 22 when the leg frame 20 descends and to ensure smooth sliding.

[0029] In this case, the protective layer 15 has a mixed composition in the ratio of 20 to 40% by weight of polysulfone resin, 1 to 10% by weight of sepiolite, 10 to 30% by weight of epoxy vitrimer resin, 5 to 20% by weight of potassium chromate, 5 to 10% by weight of cobalt naphthenate, 1 to 10% by weight of phenylalanine 4-hydroxylase, 1 to 5% by weight of polybenzimidazole, 5 to 10% by weight of lithium hydroxide, 1 to 10% by weight of isoflavonoid, 1 to 10% by weight of polycaprolactone, and 1 to 10% by weight of sodium fluoride.

[0030] In this configuration, when the leg frame 20 is lowered, the shock absorbing pad 13 and the protective layer 15 can reduce the generation of shock and noise at the leg frame 20.

[0031] That is, the first guide roller 21 is supported by the buffer pad 13 supported by the buffer spring 14, so that the occurrence of a sudden shock during the downward movement can be prevented, and the second guide roller 21 can reduce the occurrence of contact noise by the protective layer 15.

[0032] In particular, since the protective layer 15 contains a sepiolite component, the durability of the coating can be improved, potassium chromate and cobalt naphthenate prevent the occurrence of agglomeration during the coating process due to the catalytic function of polysulfone resin, phenylalanine 4-hydroxylase prevents discoloration and whitening of the protective layer 15, and polybenzimidazole and lithium hydroxide increase the coating density. In addition, the added isoflavonoid improves the coating lubricity, and polycaprolactone and sodium fluoride improve the elasticity of the protective layer 15 and prevent the occurrence of cracks, respectively.

[0033] Although specific embodiments of the present invention have been described and illustrated above, it will be apparent that the bed lifting device structure of the present invention can be modified and embodied in various ways by those skilled in the art.

[0034] However, such modified embodiments should not be understood separately from the technical spirit and scope of the present invention, and such modified embodiments should be included within the appended claims of the present invention. [Explanation of symbols]
