Description

Technical Field

[0001] The present invention relates to a manually lifting folding bed, and more particularly to a folding bed which improves space efficiency when moving or not in use through a folding structure of a health care function bed, and can manually 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 has been launched. This type of bed can perform thermal therapy with heating function, massage with massage tools, or physical therapy, etc.

[0003] Since this 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, it still has the inconvenience of occupying indoor space.

[0024] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] 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.

[0026] 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.

[0027] First, refer to Figures 1 to 14 A manually liftable folding bed structure according to an embodiment of the present invention is described.

[0028] The lifting folding bed of this embodiment includes: an iron main frame 10 with 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 folding leg 30, the upper end of which is rotatably and foldably connected to the leg frame 20; a guide rail 15, which is arranged at the lower part of both sides of the main frame 10 to guide the sliding of the leg frame 20; a movable plate 40, which is arranged at the front end of the guide rail 15 and has a guide hole 41 formed on the inner side to perform the lifting and lowering action of the rear end of the leg frame 20; a guide roller 50, which is inserted into the guide hole 41 and fixed to the side wall surface of the main frame 10 in the guide hole 41 to guide the movement of the movable plate 40; a locking wheel 42, which is arranged at one side of the movable plate 40; a locking member 22, which is arranged at the rear end of the leg frame 20 so as to be locked to the locking wheel 42; and a moving roller 23, which is arranged at one side of the locking member 22 and moves along the guide rail 15.

[0029] At this time, the main frame 10 is provided with a first spring 11 and a second spring 12 connected to the two ends of the movable plate 40 and transmitting elastic force, the first spring 11 is connected to a connecting wire 11a, and the main frame 10 is provided with a connecting wire guide roller 13 for guiding the connecting wire 11a.

[0030] In addition, a movable wheel 43 that can move along the guide rail 15 is provided at one end of the movable plate 40, and a locking wheel 42 is provided at the other end. The locking member 22 is locked on the locking wheel 42 to apply force, and while the guide roller 50 moves along the guide hole 41, the movable plate 40 stands up.

[0031] In addition, from Figure 1 A partial enlarged view of Fig. 9 It can be confirmed that the main frame 10 is provided with an anti-separation protrusion 16 , and when the moving wheel 43 slides along the guide rail 15 in a certain section, the anti-separation protrusion prevents separation.

[0032] In addition, the guide hole 41 is formed into an irregular streamline shape, and a friction reducing layer 41a is provided on the inner side of the guide hole 41 for reducing the contact friction with the guide roller 50. Fig.14 As shown, it is preferably formed by thin film coating.

[0033] At this time, the friction reducing layer 41a forms 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.

[0034] By forming the friction reducing layer 41 a , the friction force with the guide roller 50 is reduced, the roller is guided more smoothly, and the generation of noise can be prevented.

[0035] In particular, since the friction reducing layer 41a 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 the discoloration and whitening of the friction reducing layer 41a, 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 respectively improve the elasticity of the friction reducing layer 41a and prevent cracks from occurring.

[0036] Next, the effects produced by the operation of the lift-type folding bed of the present invention constructed as described above will be described.

[0037] The folding bed of the present invention can be used for various functions such as heat therapy, massage or physical therapy. The leg frame 20 for supporting the lower body can be used and stored by lifting, sliding and folding on one side of the main frame 10 supporting the upper body.

[0038] Figure 1 and Figure 2 The leg frame 20 is shown in a state where it is inserted and stored in a folded manner in the main frame 10. In this state, in order to use the bed, the user manually pulls out the leg frame 20 to drive the leg frame 20 upward.

[0039] That is, at this time, when the leg frame 20 is stretched, the moving roller 23 provided at the rear end slides along the guide rail 15, and when all stretching is completed, as shown in FIG. Figures 3 to 6 As shown, when the locking member 22 is locked on the locking wheel 42 , the sliding pulling force of the leg frame 20 is transmitted to the movable plate 40 .

[0040] Thus, the movable plate 40 subjected to the pulling force of the leg frame 20 is Figures 7 to 9 In the movement shown, as the moving wheel 43 is guided along the guide rail 15, the locking wheel 42 side rises together with the leg frame 20.

[0041] At this time, it can be confirmed that the movable plate 40 rotates while being guided by the guide rollers 50 provided in the guide holes 41 .

[0042] In addition, since there are elastic effects of the first spring 11 and the second spring 12 on both sides of the movable plate 40, the movement by interaction with the guide roller 50 can be performed more smoothly.

[0043] Furthermore, when the moving wheel 43 continues to move to the end of the guide rail 15, the movable plate 40 continues to move due to the guiding effect of the guide hole 41 and the guide roller 50, so that Fig.10 and Fig.11 As shown in FIG. 1 , one side of the leg frame 20 is in a raised state.

[0044] Afterwards, if Fig.12 and Fig.13 As shown, by rotating the folding leg 30 on the other side and vertically positioning it, the installation of the bed is completed.

[0045] On the other hand, when the leg frame 20 that has been pulled out and raised is lowered again and then retracted to its original position, after folding the folding legs 30 in the reverse order to the above, force is applied to the leg frame 20 to apply a pulling force. At this time, the leg frame 20 is lowered according to the movement of the movable plate 40, and then, the leg frame 20 is introduced into the interior of the main frame 10 so that it can be stored in a reduced size.

[0046] Therefore, the folding bed of the present invention can be manually raised and lowered to slide and fold the leg frame, thereby not only improving the convenience of use but also making it easy to move and store.

[0047] 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.

[0048] 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.
