Description

Technical Field

[0001] The present invention relates to an automatic lifting folding bed, and more particularly to a folding bed which improves the space efficiency when moving or not in use through the folding structure of a health care function bed and can automatically perform a lifting action for folding. Background Art

[0002] In recent years, as people's concern for health has increased, functional bedding with various therapeutic functions such as heat therapy with heating function, massage with massage tools or physical therapy has been launched.

[0003] Since such a functional bed needs to have a length corresponding to the height of an adult, when the frame is manufactured, it is manufactured into a predetermined length and then transported to consumers or sales stores.

[0004] However, since the conventional treatment bed has an integrated structure, it takes up space during transportation or storage, and is therefore difficult to store and move. Even when the user does not use the bed, there is the inconvenience of occupying indoor space.

[0038] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] The embodiments of the present invention can be modified into various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those of ordinary skill in the art.

[0040] Therefore, the shapes of the components expressed in the figures may be exaggerated to emphasize a clearer description. In addition, it should be noted that the same reference numerals are marked on the same structures in each figure. In addition, the detailed description of the functions and structures of the known technologies that are judged to be unnecessary to obscure the main purpose of the present invention may be omitted.

[0041] First, refer to Figures 1 to 13 An automatic lifting folding bed structure according to an embodiment of the present invention is described.

[0042] The folding bed in this embodiment has a basic structure, including: a main frame 10, having a predetermined height to support the upper body of the user; a leg frame 20, connected to one side of the main frame 10 to support the lower body of the user; a plurality of folding legs 30, the upper ends of which are rotatably and foldably connected to the leg frame 20; and an actuator 40, connected to the upper portion for rotationally driving the folding legs 30.

[0043] At this time, a lifting guide part 11 is provided on one side of the main frame 10 in the vertical direction to guide the rise and fall of the leg frame 20, and a first guide roller 21 is provided on the corresponding leg frame 20, and the first guide roller guides along the lifting guide part. 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 action of the leg frame 20, and a second guide roller 22 is provided at one end of the corresponding leg frame 20, and the second guide roller moves along the sliding guide rail 12.

[0044] In addition, the first guide roller 21 is formed as A shaped support frame 21a is connected and supported to the leg frame 20, and is rotatably connected to the support frame 21a via a rotation shaft 21b.

[0045] In addition, the upper ends of the two front and rear folding legs 30 are connected to each other via a connecting frame 32, and the folding action is performed simultaneously around the rotation axis by driving the actuator 40.

[0046] The following describes the effects of the operation of the liftable folding bed according to the present invention having the above structure.

[0047] The bed of the present invention can be used for various functions, such as heat therapy, massage or physical therapy. The leg frame 20 supporting the lower body can be connected to one side of the main frame 10 supporting the upper body in a lifting, sliding and folding manner.

[0048] Figures 1 to 7 The leg frame 20 is shown in a state where it is raised to the same height as the main frame 10. In this state, when the bed is to be folded for transportation or storage, the leg frame 20 is first lowered.

[0049] That is, at this time, when the rotation folding of the folding leg 30 is performed by the operation of the actuator 40, as shown in FIG. Figure 8 and Fig. 9 As shown, the leg frame 20 gradually descends, and at this time, the first guide roller 21 formed on one side is guided to descend by the lifting guide part 11, so that the leg frame 20 can be lowered while maintaining a stable horizontal state.

[0050] It can be seen in particular that during the descending action, when the actuator 40 is in operation, since the four folding legs 30 are connected to each other via the connecting frame 32, the folding rotation can be performed simultaneously.

[0051] And it can be confirmed that after the descending action is completed, the Figures 10 to 12 In the state shown, the second guide roller 22 formed at the end of the leg frame 20 is seated on the slide rail 12 .

[0052] In this state, when the user applies force to insert the leg frame 20 into the interior of the main frame 10, the second guide roller 22 slides along the sliding guide rail 12 to guide and complete the insertion of the leg frame 10, thereby finally achieving Figures 13 to 15 Storage condition shown.

[0053] On the other hand, to use the bed, the leg frame 20 is pulled in the reverse order to the above, and the actuator 40 is operated in the state of being pulled out from the main frame 10, so that the leg frame 20 gradually rises and performs an operation of returning to the original state.

[0054] Therefore, the folding bed of the present invention can automatically perform a descending action to execute the sliding folding of the leg frame, thereby having the effect of not only improving the convenience of use but also making it easier to move and store.

[0055] Fig.16 The structure of another embodiment according to the present invention is shown, in which a buffer pad 13 is formed at the front end portion of the sliding guide rail 12 formed on the main frame 10, so that the impact of the first guide roller 21 is absorbed when the leg frame 20 descends, and the lower portion of the buffer pad 13 is elastically supported by a buffer spring 14, and the buffer spring 14 is formed in a pad groove 14a on the sliding guide rail 12.

[0056] In addition, a protective layer 15 is coated on the sliding guide rail 12 to reduce the impact of the second guide roller 22 when the leg frame 20 descends and ensure smooth sliding.

[0057] At this time, the protective layer 15 is formed into a mixed composition with a ratio of 20 to 40 weight % of polysulfone resin, 1 to 10 weight % of sepiolite, 10 to 30 weight % of epoxy glass resin, 5 to 20 weight % of potassium chromate, 5 to 10 weight % of cobalt naphthenate, 1 to 10 weight % of phenylalanine tetrahydroxylase, 1 to 5 weight % of polybenzimidazole, 5 to 10 weight % of lithium hydroxide, 1 to 10 weight % of isoflavone, 1 to 10 weight % of polycaprolactone, and 1 to 10 weight % of sodium fluoride.

[0058] With such a configuration, when the leg frame 20 is lowered, the shock and noise generated in the leg frame 20 can be reduced by the structure of the cushion pad 13 and the protection layer 15 .

[0059] That is, the first guide roller 21 is buffer-supported by the buffer pad 13 supported by the buffer spring 14 , thereby preventing a sudden impact during the descending process, and the second guide roller 21 can reduce contact noise by the protective layer 15 .

[0060] In particular, since the protective layer 15 is mixed with a sepiolite component, the durability of the coating can be improved, and potassium chromate and cobalt naphthenate prevent agglomeration during the coating process through the catalytic function of the polysulfone resin, phenylalanine tetrahydroxylase prevents discoloration and whitening of the protective layer 15, and polybenzimidazole and lithium hydroxide increase the density of the coating. In addition, the additionally added isoflavone improves the lubricity of the coating, and polycaprolactone and sodium fluoride each improve the elasticity of the protective layer 15 and prevent cracks from occurring.

[0061] In addition, although the above description and illustrations are specific embodiments of the present invention, it is obvious that the structure of the bed lifting device of the present invention can be variously modified and implemented by ordinary technicians in this field.

[0062] However, such modified embodiments should not be understood solely from the technical spirit or scope of the present invention, and such modified embodiments should be included in the scope of the appended claims of the present invention.
