Description

Rotary lifting bed TECHNICAL FIELD

[0001] The present application belongs to the technical field of furniture structure, and particularly relates to a rotary lifting bed. BACKGROUND

[0002] The common ordinary bed in the prior art mainly comprises a bed frame, a bed plate, a backrest and a mattress. When a user needs to sit up and lean, the user can only lean on the backrest. At this time, the user's waist lacks sufficient support, and the above-mentioned leaning posture is relatively laborious and uncomfortable.

[0003] Therefore, further, a "two-section" bed plate appears, that is, the bed plate is divided into two parts. Generally, the head end bed plate can be rotated and raised to an inclined state to more comfortably support the user's waist and back, while the foot end bed plate is generally fixed.

[0004] For example, the Chinese utility model patent with the authorization announcement number CN221084019U and the authorization announcement date of 2024.06.07 discloses a disassemblable multifunctional medical bed. The structure comprises a bed frame and a bed plate arranged on the bed frame. The bed plate is divided into two left and right symmetrical and independent first bed plates for bearing the upper body and two left and right symmetrical and independent second bed plates for bearing the lower body. The freedom degree of each first bed plate is that the first bed plate head end rotates upward. The back surface of each first bed plate is provided with a first telescopic rod. The extension direction of the first telescopic rod is toward the side of the adjacent first bed plate.

[0005] The multifunctional medical bed in the utility model patent has the following general structure principle and advantages: the bed plate is divided into four separate parts, and the back surface of the bed plate is provided with telescopic rods. When a first bed plate is individually supported, it can support half of the torso. Therefore, the patient does not need to turn over to process the back of the body, and the convenience of use is improved.

[0006] However, the multifunctional medical bed has at least the following two deficiencies in actual use, which are also the technical problems to be solved by the present application, namely:

[0007] Firstly, the bed plate structure and the jacking mechanism are directly hinged in combination, which makes it inconvenient to individually disassemble and replace the bed plate and the jacking mechanism.

[0008] Secondly, due to the above-mentioned direct hinged structure, there is no adjustable proportional relationship between the jacking amplitude of the jacking mechanism and the rotation amplitude of the bed plate structure, which greatly reduces the practicality of the multifunctional medical bed.

[0009] Therefore, it is urgent to provide a new lifting bed with a bed plate rotating structure separated from a jacking structure and more flexible and practical bed plate rotating use. SUMMARY

[0010] The application provides a rotary lifting bed, which is characterized by arranging a hinged combination plate unit, a rotating rod unit and a lifting block unit on a bed frame unit, so that: 1. the rotating rod unit and the hinged combination plate unit are separated from each other, and the two units are relatively simple and convenient to maintain and replace; 2. the lifting block unit provides a proportionally adjustable basis between the rotating angle of the rotating rod unit and the lifting amplitude of the hinged combination plate unit, so that the lifting bed is more flexible to use.

[0049] The following description is merely exemplary of the application and is not intended to limit the application.

[0050] As shown in FIGS. 1-11, a rotary lifting bed comprises a bed frame unit 1, a hinged combination plate unit 2 installed on the bed frame unit 1, a rotary rod unit 3 installed on the bed frame unit 1, and a lifting block unit 4 installed on the rotary rod unit 3 and used to lift the hinged combination plate unit 2.

[0051] In this embodiment, the structure of the lifting bed further comprises a bed mattress 11, which is a commercially available product, but is required to be flexible with the rotary lifting action of the hinged combination plate unit 2, so as to still fully support the user's waist and back.

[0052] The bed frame unit 1 is rectangular in shape and made of steel and wood, and functions to fixedly install the non-rotating part of the hinged combination plate unit 2 and stably place the bed mattress 11.

[0053] In addition, the structure of the hinged combination plate unit 2 mainly comprises a fixed installation part and a rotary lifting part. The former is fixedly installed on the bed frame unit 1, and the latter is used to receive the rotary lifting effect of the lifting block unit 4.

[0054] In addition, the rotary rod unit 3 directly drives the lifting block unit 4 to rotate, and the height of the lifting block unit 4 changes, i.e., the rotary lifting part of the hinged combination plate unit 2 is lifted upward or lowered downward.

[0055] Finally, the lifting block unit 4 has the following structural and functional advantages:

[0056] First, the lifting block unit 4 only contacts with the hinged combination plate unit 2 without being connected, so that the hinged combination plate unit 2 as a whole and the rotary rod unit 3 and the lifting block unit 4 as a whole can be independently disassembled and replaced.

[0057] Second, the lifting block unit 4 itself has adjustable functions of position, quantity, size, angle and other parameters, including pre-set parameter adjustment at the factory and temporary parameter adjustment during use, so that the rotary lifting action of the rotary rod unit 3 on the hinged combination plate unit 2 is more flexible and practical.

[0058] If the lifting block unit 4 is not provided, the rotary lifting action can only be adjusted by adjusting the hinged combination plate unit 2 and the rotary rod unit 3, which has relatively few adjustment modes and relatively poor adjustment effect. Moreover, the lifting bed provided with the lifting block unit 4 can still adjust the hinged combination plate unit 2 and the rotary rod unit 3, which do not affect each other, only the adjustment effect is improved and strengthened.

[0059] The bed frame unit 1 comprises two bed body side plates 101 and inner side protruding plates 102 provided on the opposite sides of the bed body side plates 101 and used for supporting the hinged combination plate unit 2.

[0060] In the embodiment, the length of the bed body side plate 101 corresponds to the length of the lifting bed, and the inner side protruding plate 102 is welded or screwed on the bed body side plate 101 to directly support the hinged combination plate unit 2 and indirectly support the mattress 11.

[0061] The hinged combination plate unit 2 comprises a fixed plate 201 provided on the inner side protruding plate 102, a hinge 202 provided on the fixed plate 201, and a rotating plate 203 provided on the hinge 202 and used for receiving the jacking action of the lifting block unit 4.

[0062] In the embodiment, one of the ways of fixedly installing the fixed plate 201 on the inner side protruding plate 102 is screwing. The hinge 202 is a commercially available product, and the number is 2-3.

[0063] The rotating plate 203 and the fixed plate 201 are both rectangular in shape, have the same length, and the width of the former is greater than that of the latter. The width of the two corresponds to the width of the lifting bed.

[0064] In addition, the fixed plate 201 and the rotating plate 203 are made of composite wood plates, which can ensure sufficient support strength and relatively light self-weight.

[0065] The rotary rod unit 3 comprises a hinged air cylinder 301, a rotary cross rod 302 provided on the bed body side plate 101, and a hinged hole plate 303 provided on the rotary cross rod 302 and connected to the hinged air cylinder 301.

[0066] In the embodiment, the cylinder shaft of the hinged air cylinder 301 is extended to drive the rotary cross rod 302 and the lifting block unit 4 to rotate together, and finally jacks up the rotating plate 203, which is the above-mentioned "rotary lifting" effect.

[0067] Conversely, the cylinder shaft of the hinge cylinder 301 is retracted, i.e. the rotating plate 203 is slowly lowered to change from the tilted state to the horizontal state. During this process, the lifting block unit 4 is still supporting and pressing against the rotating plate 203. In other words, when the rotating plate 203 remains in the tilted state, the hinge cylinder 301 needs to work continuously, i.e. it has sufficient airtightness and the air leakage can be ignored, or an external air pump is always supplementing the air leakage.

[0068] The opening structure on the hinge hole plate 303 is used to connect the opening on the cylinder shaft of the hinge cylinder 301. The hinge hole plate 303 and the rotating cross rod 302 are fixed by welding, one-piece forming or screwing, etc. Finally, the cylinder shaft is extended, the lifting block unit 4 can rotate and rise, and the cylinder shaft is retracted, the lifting block unit 4 can rotate and fall, ensuring that the rotating plate 203 can rotate controllably, and the lifting bed has the automatic one-end lifting function.

[0069] On the other hand, the one-end that can be lifted is generally the head end of the lifting bed, but in special cases, it can also be the foot end, for example, when the lifting bed is used in the scene of foot medical care.

[0070] The lifting block unit 4 includes a supporting block 401 arranged on the rotating cross rod 302 and / or the hinge hole plate 303 and used to lift the rotating plate 203.

[0071] In this embodiment, when the cylinder shaft of the hinge cylinder 301 is fully retracted, the supporting block 401 does not touch the lower surface of the rotating plate 203. When the cylinder shaft is extended, the supporting block 401 and the rotating cross rod 302 rotate together, the height of the former is constantly increased, and finally the rotating plate 203 can be lifted to realize the "rotary lifting" effect.

[0072] It should be noted that the angular velocity of the supporting block 401 and the rotating cross rod 302 is consistent, but the linear velocity is different. Therefore, when necessary, the supporting block 401 can appropriately accelerate the rotating and rising speed and the rotating and lowering speed of the rotating plate 203 by increasing the linear velocity.

[0073] However, it should be noted that for the rotating plate 203, the supporting position of the supporting block 401 on the lower surface thereof cannot be too close to the hinge 202, otherwise the upper half of the rotating plate 203 that has been rotated and lifted is not stable enough.

[0074] If the linear speed of the support block 401 is too large, it proves that the radius of rotation of the support block 401 is too large, and at this time, the force with which the rotating plate 203 presses on the support block 401 needs the longer radius to support, which is also unstable.

[0075] Therefore, the radius of rotation of the support block 401 should not be too small or too large, and the more preferable way is that the support position of the support block 401 on the rotating plate 203 is located at the middle 1 / 3 of the width direction of the support block 401 after the rotating plate 203 rotates to the required inclination angle.

[0076] The bed frame unit 1 further comprises a support hole plate 103 arranged on the opposite side of the bed body side plate 101 and used for inserting the rotating cross rod 302.

[0077] In the embodiment, the support hole plate 103 has at least the following two functions:

[0078] First, as the middle reinforcing position of the longer bed body side plate 101, it further improves the structural stability of the lifting bed;

[0079] Second, the hole structure is used for inserting the rotating cross rod 302 to ensure that the rotating cross rod 302 does not fall off while rotating.

[0080] Among them, the hardware similar to the "U-shaped" existing common shape is arranged between the support hole plate 103 and the bed body side plate 101, which ensures that the support hole plate 103 can share the weight on the bed body side plate 101. The shape of the above hardware can be referred to in FIG. 8.

[0081] The upper end of the support hole plate 103 is arranged on the inner side protruding plate 102.

[0082] In the embodiment, the upper end surface of the support hole plate 103 is arranged on the lower surface of the inner side protruding plate 102. Therefore, the support hole plate 103 has a third function of more directly supporting the mattress 11 and a fourth function of reinforcing the connection between the bed body side plate 101 and the inner side protruding plate 102 to avoid the latter from falling off the former.

[0083] The bed frame unit 1 further comprises a bed body end plate 104 arranged on the two bed body side plates 101 and a middle plate 105 arranged on the bed body end plate 104 and used for supporting the articulated combination plate unit 2.

[0084] In the embodiment, the length of the bed body end plate 104 corresponds to the width of the lifting bed. The middle plate 105 is parallel to the bed body side plate 101 and mainly functions to support the articulated combination plate unit 2 and secondarily functions to reinforce the entire lifting bed.

[0085] When the hinged combination plate unit 2 is not rotated and raised, the fixed plate 201 and the rotating plate 203 are both pressed on the two inner side protruding plates 102 at both ends and on the middle plate 105 in the middle, so as to ensure that the hinged combination plate unit 2 is not easily broken.

[0086] When the rotating plate 203 has been rotated and raised, it is away from the inner side protruding plate 102 and the middle plate 105, and the pressure generated by the mattress 11 on it is partially applied to the hinge 202. Therefore, the number of the hinge 202 cannot be too small, and the strength cannot be too small.

[0087] The bed frame unit 1 further comprises two end head vertical plates 106 respectively arranged on the two bed body side plates 101, and two ground support plates 107 respectively arranged at both ends of the two end head vertical plates 106.

[0088] In the embodiment, the main function of the end head vertical plate 106 is to serve as a support leg of the lifting bed on the side, and the secondary function is to reinforce the rectangular frame composed of the bed body side plate 101 and the bed body end head plate 104.

[0089] On the other hand, the ground support plate 107 is generally located directly below the bed body end head plate 104 and is used to reinforce the two end head vertical plates 106.

[0090] The rotating rod unit 3 further comprises a bottom plate 304 arranged on the ground support plate 107, and a hinge hole block 305 arranged on the bottom plate 304 and used for mounting the hinged air cylinder 301.

[0091] In the embodiment, the lower surface of the bottom plate 304 is placed on the ground, and the side surface is arranged on the ground support plate 107, which makes the ground support plate 107 have a second function of serving as a fixed mounting and anti-backup position of the bottom plate 304. In addition, the bottom plate 304 can also be not connected with the ground support plate 107, and only abuts against each other.

[0092] In addition, the hinge hole block 305 is hingedly connected with the ring at one end of the non-cylinder shaft of the hinged air cylinder 301, so as to ensure that the hinged air cylinder 301 can be simultaneously rotated and the cylinder shaft can be extended and retracted.

[0093] The bed frame unit 1 further comprises a mattress end head baffle 108 arranged on the two bed body side plates 101 and located at the positions of the bed body end head plate 104 at both ends of the bed body side plate 101.

[0094] In the embodiment, the two bed body side plates 101, one bed body end plate 104, and one mattress end plate 108 jointly form a complete rectangular frame of the lifting bed, and are fully connected and fixed by commonly used hardware.

[0095] In addition, the upper surface of the mattress end plate 108 must be higher than the upper surface of the inner protruding plate 102, and is preferably higher than the upper surface of the inner protruding plate 102. The upper surface height difference is set to avoid the bent mattress 11 from sliding out of the non-lifting end of the lifting bed.

[0096] Correspondingly, the other end of the middle plate 105 is connected to the mattress end plate 108, so that the strength of the frame structure of the lifting bed is further enhanced.

[0097] The support block 401 is in the shape of a circular ring, and the lifting block unit 4 further includes a fixing shaft 402 for inserting the support block 401.

[0098] In the embodiment, the circular ring-shaped support block 401 and the fixing shaft 402 are used in combination, and the advantages of this mode include at least the following three aspects:

[0099] First, the original sliding friction between the support block 401 and the lower surface of the rotating plate 203 is replaced by rolling friction, so that the frictional resistance is smaller and frictional noise is less likely to occur;

[0100] Second, the support block 401, which is the direct force application part of the rotating lifting action, is convenient to replace;

[0101] Third, the fixing shaft 402 can switch the installation position, that is, the rotating radius of the support block 401 can be simply and conveniently adjusted, so that the rotating speed of the rotating plate 203 and the supported position are flexibly adjustable.

[0102] The fixing shaft 402 itself is not rotatable, the support block 401 is rotatable on the fixing shaft 402, and has an end limiting function to avoid the support block 401 from falling off the fixing shaft 402.

[0103] The lifting block unit 4 further includes a radial extension plate 403 arranged on the rotating horizontal rod 302 and used for installing the fixing shaft 402.

[0104] In the embodiment, the combination structure of the support block 401 and the fixing shaft 402 mainly has two installation modes:

[0105] First, the fixed shaft 402 is directly installed on the hinged hole plate 303, and the length of the hinged hole plate 303 is the length of the rotating radius of the support block 401.

[0106] Second, the fixed shaft 402 is installed on the radial extension plate 403, and the length of the radial extension plate 403 is the length of the rotating radius of the support block 401.

[0107] The first mode has the advantage of saving the radial extension plate 403, and the disadvantage of being limited by the hinged hole plate 303 in the number and position of the support block 401. The second mode has the opposite advantages and disadvantages, and the two modes can be selected.

[0108] The bed frame unit 1 further comprises a mattress support plate 109 arranged on the two bed body side plates 101 and located at the ends of the bed body side plates 101.

[0109] In this embodiment, the mattress support plate 109 and the hinged combination plate unit 2 together cover most of the open area of the above-mentioned rectangular frame, so that the mattress 11 can be fully supported.

[0110] The number of mattress support plates 109 is 5-10, and the two ends are respectively erected on the two inner side protruding plates 102, i.e. indirectly arranged on the bed body side plates 101.

[0111] The bed frame unit 1 further comprises a backrest connecting plate 110 arranged on the two end vertical plates 106.

[0112] In this embodiment, the first function of the backrest connecting plate 110 is to connect the two end vertical plates 106, so that the upper and lower parts of the end vertical plate 106 are reinforced.

[0113] The second function of the backrest connecting plate 110 is to expand its function, and functional accessories such as soft bags, extension cords, shelves, etc. can be arranged thereon.

[0114] The hinged combination plate unit 2 further comprises a clamping block 204 arranged on the inner side protruding plate 102 and used to transversely block the fixed plate 201.

[0115] In this embodiment, in addition to the screwing method described above, the method of fixing the fixed plate 201 transversely on the inner side protruding plate 102 can also be set as the blocking method of the clamping block 204.

[0116] The latter blocking mode has a fixed strength, which may not be as good as the screwing mode, but has the advantage that the hinged combination plate unit 2 has no fixed installation position and is convenient to replace. For details, please refer to Figure 7.

[0117] The number of the hinged air cylinders 301 is 1 or 2.

[0118] In the embodiment, when the number of the hinged air cylinders 301 is 2, they are respectively located on both sides of the intermediate plate 105, and both are arranged on the same large-size bottom plate 304 or are respectively arranged on two small-size bottom plates 304.

[0119] The number of the lifting block units 4 is 2-4.

[0120] In the embodiment, the 2-4 lifting block units 4 are uniformly arranged in the length direction of the rotating cross rod 302, so as to symmetrically and comprehensively support the rotating plate 203.

[0121] In addition, the rotating cross rod 302 is located at a position below the intermediate plate 105 and is not easy to be bent by the mattress 11, so as to ensure that all the lifting block units 4 have the same rotating center axis, and finally the rotating plate 203 obtains a stable supporting effect with consistent supporting force, thereby avoiding bending of the rotating plate 203 itself.

[0122] The bed body side plate 101 and the intermediate plate 105 are provided with a jointing fracture.

[0123] In the embodiment, the bed body side plate 101 and the intermediate plate 105 are divided into two parts at the midpoint in the length direction, so that the maximum length of the assembly parts of the lifting bed is not large, and the transportation and storage operation of the lifting bed before use is facilitated.

[0124] Correspondingly, the bed body side plate 101 and the inner side protruding plate 102 thereon are also divided into two parts in the length direction.

[0125] The bed frame unit 1 further comprises an auxiliary bed leg 111 arranged on the jointing fracture.

[0126] In the embodiment, the number of the auxiliary bed legs 111 is 3, corresponding to the two bed body side plates 101 having the jointing fracture and the one intermediate plate 105 also having the jointing fracture.

[0127] Up to now, the lifting bed has a total of 9 supporting legs and structures similar to the supporting legs, specifically, 2 end head vertical plates 106, 2 supporting hole plates 103, 3 auxiliary bed legs 111, and 2 bed body supporting legs 112, so as to ensure that the lifting bed has sufficient structural stability.
