Description

Technical Field

[0001] This invention relates to the technical field of furniture, and more particularly to a caregiver's bed. Background Technology

[0002] Beds are commonly used in bedrooms, dormitories, hospital wards, and hotels, serving as essential items for people's daily sleep. Traditional bed furniture typically consists of a bed frame and a headboard, with a relatively simple function: primarily for daily sleep.

[0003] When someone is injured and unable to move around easily but not to the point of hospitalization, they often choose to recuperate at home. Currently, due to the fast pace of life and family responsibilities of young people, many resume work while recovering at home after an injury. However, using a home bed for work is not very convenient for young people because the design of traditional home beds does not adequately meet work requirements. Therefore, there is still room for improvement. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a nursing bed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A nursing bed includes a bed frame, a nursing table slidably connected to the bed frame, the nursing table including a support frame slidably connected to the bed frame and a tabletop connected to the support frame, the tabletop having a tray for placing a laptop computer, the tabletop having a recessed mounting groove for placing the tray, a rotating rod fixed to one end of the tray near the head of the bed frame, the rotating rod being integrally formed with the tray, one end of the rotating rod being rotatably connected to the groove wall of the mounting groove, the end of the rotating rod away from the mounting groove passing through the tabletop and protruding from the side of the tabletop near the tray, and a fixing member on the tabletop for limiting the rotation of the rotating rod.

[0007] By adopting the above technical solution, the sliding connection between the bed and the care table allows the care bed to better meet the needs of injured people who need to work. The integrated molding of the tray and rotating rod, along with the inclusion of fixing components, allows the rotating rod to adjust the tilt between the tray and the tabletop. Furthermore, adjusting the fixing components locks the rotating rod, ensuring the tray remains stable in the desired position. This allows the care table to better meet the needs of injured young people recuperating at home, improving the practicality of the care bed. Simultaneously, it facilitates better placement of laptops on the tray, allowing the injured person lying on the care bed to more clearly view the laptop screen. This reduces the difficulty of adjusting the screen position due to the laptop's flat placement on the table, which can hinder screen glare and make viewing difficult. This allows for better screen adjustment and ultimately, greater comfort while working on the care bed.

[0008] The present invention is further configured such that: the fixing member includes a push disk slidably connected to the rotating rod, the push disk having a plurality of fixed round rods on the side near the table, and the table having a plurality of locking grooves for the fixed round rods to be inserted into on the side near the push disk, and the plurality of locking grooves being respectively opposite to the plurality of fixed round rods.

[0009] By adopting the above technical solution, after the tray is adjusted to a suitable position, the drive disk moves towards the tabletop, causing the fixed rod on the drive disk to engage with the locking slot, thus preventing the rotating rod from rotating and fixing the tray. This helps to reduce the possibility of the rotating rod rotating due to insufficient friction between the fixing component and the rotating rod, which could cause the tray to rotate and the laptop placed on the tray to fall and be damaged. This reduces the occurrence of accidents during the use of the care bed tray and improves the stability of the tray.

[0010] The invention is further configured such that: the fixed cylindrical rod includes a crossbar fixed to the side of the pushing disk near the table surface and a support column; the outer wall of the crossbar near the pushing disk is inclined towards the pushing disk; the inclined portion of the crossbar is a truncated cone shape; the radius of the connection between the inclined portion and the pushing disk is smaller than the radius of the crossbar; the support column is cylindrical; one end of the support column is connected to the pushing disk; the radius of the support column is the same as the radius of the crossbar; the support column has a through hole through which the inclined portion can completely pass; the axis of the support column coincides with that of the crossbar, and there is a gap between the support column and the inclined portion.

[0011] Using the above technical solution, when the rotating rod rotates to make the pallet rotate and pushes the pushing disc, causing the fixed round rod on the pushing disc to abut against the locking groove, since the rotating rod and the pallet are integrally formed, the inclined pallet is subjected to gravity, causing the rotating rod to tend to rotate. This means that when the fixing component secures the rotating rod, the groove wall of the locking groove will exert a force on the fixed round rod. When there is a heavy object on the pallet, it will increase the force of the locking groove on the fixed round rod, which may easily lead to breakage at the connection between the fixed round rod and the pushing disc. Through the setting of the load-bearing column, since the length of the load-bearing column is shorter than the length of the crossbar, when the fixed round rod is subjected to force, the load-bearing column... The moment of the support column is smaller than that of the crossbar, resulting in a smaller force on the support column compared to the crossbar. This makes the connection between the support column and the push disk less prone to breakage. Simultaneously, the support column actively shares the force exerted on the crossbar by the groove wall of the locking slot, reducing the force on the crossbar and thus the force at the connection between the crossbar and the push disk, thereby improving the stability of the connection. Furthermore, because the support column shares the force on the crossbar, the overall radius of the fixed rod can be made smaller, improving the adjustment accuracy of the support plate, and also making the connection between the fixed rod and the push disk less prone to breakage.

[0012] The present invention is further configured such that: a supporting ring is provided on the side wall of the inclined portion, one end of the supporting ring is connected to the inclined surface of the inclined portion, and the end of the supporting ring away from the inclined portion is connected to the load-bearing column.

[0013] By employing the above technical solution, and through the setting of the supporting ring, when the rotating rod rotates to make the pallet rotate and pushes the pushing disk, causing the fixed rod on the pushing disk to abut against the locking groove, since the rotating rod and the pallet are integrally formed, the inclined pallet, under the action of gravity, causes the rotating rod to tend to rotate. This results in the locking groove wall exerting a force on the crossbar and the load-bearing column. Furthermore, the supporting ring ensures that the crossbar and the load-bearing column are integrated, preventing excessive force on the load-bearing column from causing breakage at the connection between the load-bearing column and the pushing disk. The supporting ring disperses the force to the crossbar, allowing the crossbar and the support column to share the force, thus preventing breakage at the connection between the support column and the push disk. Simultaneously, when excessive force from the locking groove wall causes the connection between the crossbar and the push disk to break, the supporting ring disperses the excessive force to the support column, ensuring that the crossbar and the support column share the force, further reducing the risk of breakage at the connection and improving stability.

[0014] The present invention is further configured such that: a fixing ring is provided on both sides of the supporting ring along the thickness direction and at one end near the load-bearing column, and the fixing rings on both sides intersect with the connection of the supporting ring.

[0015] By adopting the above technical solution, the fixed rings form a stable triangular support structure. When the load-bearing column applies force to the crossbar through the support rings, a portion of the force applied by the load-bearing column to the support rings is distributed to the fixed rings. Furthermore, since the ends of the fixed rings furthest from the load-bearing column intersect, a portion of the force borne by the two fixed rings is in opposite directions, and these opposing forces cancel each other out, reducing the force applied by the load-bearing column to the support rings. This, in turn, reduces the force applied by the load-bearing column to the crossbar through the support rings, making the connection between the crossbar and the pushing disc more stable. Simultaneously... When the crossbar applies force to the support column through the supporting rings, a portion of the force exerted by the crossbar on the supporting rings is distributed to the fixed rings because the two fixed rings form a stable triangular structure with the support column. Furthermore, a portion of the force on the two fixed rings is in opposite directions, causing a portion of the force on the two fixed rings to cancel each other out. This reduces the force exerted by the crossbar on the support column through the supporting rings, thereby making the connection between the support column and the push disk more stable. In addition, the support of the fixed rings on the supporting rings makes the connection between the supporting ring and the support column less prone to breakage.

[0016] The invention is further configured such that: stabilizing rings are provided on both sides of the supporting ring along the thickness direction and at one end near the inclined portion, and the connection points of the stabilizing rings on both sides intersect with the supporting ring.

[0017] By adopting the above technical solution, the stabilizing ring forms a stable triangular support structure. When the crossbar applies force to the support column through the support ring, a portion of the force applied by the crossbar to the support ring is decomposed onto the stabilizing ring. Since the ends of the stabilizing rings furthest from the support column intersect, a portion of the force borne by the two stabilizing rings is in opposite directions, and these opposing forces cancel each other out, reducing the force applied by the crossbar to the support ring, and consequently reducing the force applied by the crossbar to the support column through the support ring. This makes the connection between the support column and the push disk more stable. Simultaneously… When the load-bearing column applies force to the crossbar through the supporting rings, because the two stabilizing rings and the crossbar form a stable triangular structure, part of the force applied by the load-bearing column to the supporting rings is decomposed onto the stabilizing rings. Furthermore, part of the force on the two stabilizing rings is in opposite directions, causing part of the force on the two stabilizing rings to cancel each other out. This reduces the force applied by the load-bearing column to the crossbar through the supporting rings, thereby making the connection between the crossbar and the push disk more stable. In addition, because the stabilizing rings support the supporting rings, the connection between the supporting rings and the crossbar is less prone to breakage.

[0018] The present invention is further configured such that: the rotating rod is also provided with a limiting member for restricting the sliding of the pushing disk.

[0019] By adopting the above technical solution, the sliding of the pushing block is restricted by the limiting component, so that when the pushing disc is pressed against the slot of the locking groove, the pushing block can be stably pressed against the slot of the locking groove. This helps to reduce the situation where the pushing disc slides due to the shaking of the table, which causes the fixed rod to separate from the locking groove and thus the tray to rotate. This helps to improve the stability of the fixing component.

[0020] The invention is further configured such that: a T-shaped block is fixed on the rotating disk, the rotating rod is recessed with a T-shaped groove for the T-shaped block to slide, the limiting member is a magnet, the limiting member is detachably connected to the T-shaped groove, and the groove of the T-shaped groove is also lined with a material for the magnet to be attracted magnetically.

[0021] By adopting the above technical solution, the magnetic block is directly magnetically attracted to the side wall of the T-slot opening, and the magnetic block is pressed against the side of the pushing disk away from the table, which can realize the limiting of the pushing disk. This makes the operation of the limiting component simple and convenient, and helps to improve the operating efficiency of the limiting component.

[0022] In summary, the present invention has the following beneficial effects:

[0023] (1) The setting of the care table, rotating rod and fixing parts helps the care bed to better meet the needs of injured people who need to work on the bed, and helps people who are not convenient to move to work more conveniently and comfortably on the bed.

[0024] (2) The setting of crossbar, load-bearing column, support ring, fixed ring and stabilizing ring is conducive to the fixing of the rotating rod and to improving the stability of the pallet. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] A type of nursing bed, see Figure 1 as well as Figure 3 The device includes a bed frame 1 and a care table 2 mounted on the bed frame 1. The care table 2 includes a support frame 21 slidably connected to the bed frame 1, a desktop 3 mounted on the support frame 21, and a tray 4 rotatably connected to the desktop 3 for placing a laptop computer. The rotation angle of the tray 4 is adjustable. The support frame 21 includes a telescopic rod 211 slidably connected to the bed frame 1 for adjusting the height of the desktop 3, and bolts 212 for fixing the telescopic rod 211 at its telescopic height. The desktop 3 is located at the end of the telescopic rod 211 away from the bed frame 1. The desktop 3 has a recessed mounting groove 41 for placing the tray 4. A rotating rod 42 is fixed to the end of the tray 4 near the head of the bed frame 1. The rotating rod 42 passes through the tray 4, with one end rotatably connected to the side wall of the mounting groove 41, and the other end passing through the desktop 3 and extending beyond the side wall of the desktop 3. The desktop 3 also has a fixing component for limiting the rotation of the rotating rod 42.

[0033] See Figure 1 In this embodiment, four telescopic rods 211 are provided. The ends of the four telescopic rods 211 away from the bed body 1 are fixedly connected to the four top corners of the tabletop 3. The four telescopic rods 211 are respectively placed on both sides of the bed body 1 along the width direction, and two are provided on the same side of the bed body 1 along the width direction. The telescopic rods 211 are perpendicular to the top surface of the bed body 1. A slider is fixedly connected to the end of the telescopic rod 211 near the bed body 1. The bed body 1 has recessed movable grooves 12 for sliding on both sides along the width direction. The movable grooves 12 extend along the length direction of the bed body 1 and the length direction is consistent with the length direction of the bed body 1. The telescopic rod 211 includes a fixed rod 213 and a movable rod 214 movably connected to the fixed rod 213. The slider is fixed to one end of the fixed rod 213 along the length direction. The fixed rod 213 is hollow inside and open at the end away from the slider. The movable rod 214 moves at the open end of the fixed rod 213. The outer wall of the fixed rod 213 away from the slider has a threaded hole, and a bolt 212 is threaded into the threaded hole. By rotating the bolt 212, the bolt 212 is pressed against the movable rod 214 to fix the height of the telescopic rod 211.

[0034] See Figure 1 The distance from the mounting groove 41 to the side of the tabletop 3 near the rotating rod 42 is one-sixth of the length of the tabletop 3. The distance from the mounting groove 41 to the side of the tabletop 3 near the head of the bed frame 1 is one-quarter of the width of the tabletop 3. The length of the tray 4 is one-third of the length of the tabletop 3, and the width of the tray 4 is half the width of the tabletop 3. When the tray 4 abuts against the bottom of the mounting groove 41, the tray 4 is flush with the tabletop 3.

[0035] See Figure 3 The fixing components include a push disk 51 slidably connected to the outer wall of the portion of the rotating rod 42 extending beyond the side wall of the tabletop 3, several fixed rods 52 fixed to the side of the push disk 51 near the tabletop 3, and a locking groove 31 recessed in the side of the tabletop 3 near the fixed rods 52 for engaging the fixed rods 52. The push disk 51 is annular, with its inner diameter equal to the outer diameter of the rotating rod 42, and its inner side abutting against the outer side of the rotating rod 42. The axis of the push disk 51 coincides with the axis of the rotating rod 42.

[0036] See Figure 3 The inner wall of the pushing disc 51 is integrally connected to a T-shaped block 421, and the outer wall of the rotating rod 42 has a T-shaped groove 422 for sliding the T-shaped block 421. The T-shaped groove 422 extends along the length of the rotating rod 42. Several fixed round rods 52 are evenly distributed around the outer circumference of the rotating rod 42, meaning that the distance between any fixed round rod 52 and the rotating rod 42 is the same. Several locking grooves 31 are provided corresponding to several fixed round rods 52, and the locking grooves 31 are respectively directly opposite the locking rods 52. When the pushing disc 51 slides to the end of the T-shaped groove 422 near the outer wall of the tabletop 3, the fixed round rod 52 is fully inserted into the locking groove 31 and abuts against the bottom and inner wall of the locking groove 31; when the pushing disc 51 slides to the end of the T-shaped groove 422 away from the side wall of the tabletop 3, the fixed round rod 52 is completely separated from the locking groove 31 and a gap is left between the fixed round rod 52 and the outer side of the tabletop 3. By driving the disc 51 to move toward the outer wall of the tabletop 3, and causing several fixed round rods 52 to be inserted into several locking slots 31 and to abut against the bottom and side walls of the locking slots 31, the rotating rod 42 can be locked and cannot rotate.

[0037] See Figure 4The fixed rod 52 includes a crossbar 53 fixed to the side of the push disk 51 near the tabletop 3 and a support column 54. The crossbar 53 is cylindrical. The outer wall of the crossbar 53 near the push disk 51 is inclined toward the side of the push disk 51 near the tabletop 3 and is fixedly connected to the side of the push disk 51 near the tabletop 3. The inclined part of the outer wall of the crossbar 53 is a truncated cone shape. The radius of the connection between the inclined part 55 and the push disk 51 is smaller than the radius of the end of the crossbar 53 away from the push disk 51.

[0038] See Figure 4 The support column 54 is cylindrical, and the radius of the support column 54 is the same as the radius of the end of the crossbar 53 away from the push disk 51. One end of the support column 54 is fixedly connected to the push disk 51. The inclined part 55 passes through the support column 54. The end of the support column 54 away from the push disk 51 has a through hole for the crossbar 53 to pass through. The end of the through hole near the push disk 51 is closed by the side of the push disk 51 near the table 3. There is a gap between the support column 54 and the inclined part 55. The length of the support column 54 is less than the length of the inclined part 55.

[0039] See Figure 4 A support ring 56 is fixedly connected to the side wall of the inclined part 55. The support ring 56 is located in the gap between the inclined part 55 and the load-bearing column 54. One end of the support ring 56 is connected to the side wall of the inclined part 55, and the end of the support ring 56 away from the inclined part 55 is fixedly connected to the side wall of the through hole of the load-bearing column 54.

[0040] See Figure 4 A stabilizing ring 58 is fixedly connected to both sides of the supporting ring 56 along the thickness direction and to one end near the inclined portion 55. The end of the stabilizing ring 58 away from the supporting ring 56 is fixedly connected to the side wall of the inclined portion 55. The connection points of the two stabilizing rings 58 and the supporting ring 56 intersect. A fixing ring 57 is fixedly connected to both sides of the supporting ring 56 along the thickness direction and to one end near the side wall of the through hole. The end of the fixing ring 57 away from the supporting ring 56 is fixedly connected to the side wall of the through hole. The connection points of the two fixing rings 57 and the supporting ring 56 intersect.

[0041] See Figure 3 as well as Figure 4A limiting member 6 for restricting the sliding of the push block is detachably connected inside the T-slot 422. In this embodiment, the limiting member 6 is a magnet. The wall of the T-slot 422 is made of iron. When the push disk 51 is pressed against the opening of the slot 31, and the fixing rod 52 is inserted into the slot 31 and abuts against the bottom and side wall of the slot 31, the magnet is placed at the opening of the T-slot 422 so that the magnet is pressed against the side of the push disk 51 away from the table 3. The magnet is pressed against the side wall of the opening of the T-slot 422 by magnetism, thereby restricting the sliding of the T-block 421 in the T-slot 422, and thus restricting the sliding of the push disk 51.

[0042] The implementation principle of this embodiment is as follows:

[0043] When an injured person needs to use the care bed, first push the telescopic rod 211 to slide it along the movable groove 12, thereby adjusting the tabletop 3 to a suitable position. Then loosen the bolt 212 and pull the movable rod 214 to adjust the tabletop 3 to a suitable height. Finally, tighten the bolt 212 again to lock the telescopic rod 211, so that the tabletop 3 is stable at a suitable height.

[0044] When the computer is placed on tray 4 and tray 4 needs to be adjusted, the magnet is removed, allowing the push disc 51 to slide on the T-slot 422. By driving the push disc 51 to move away from the desktop 3, the fixed rod 52 is separated from the locking slot 31, thus restoring the rotation function of the rotating rod 42. By driving the rotating rod 42 to rotate, the rotation angle of the rotating rod 42 is adjusted, thereby adjusting the position of tray 4. When tray 4 is adjusted to the appropriate position, the push disc 51 is driven to move closer to the desktop 3, causing the fixed rod 52 to insert into the locking slot 31, and the side of the push disc 51 closest to the desktop 3 is pressed against the opening of the locking slot 31, thus fixing the rotating rod 42 in place and fixing tray 4 in the appropriate position. By rotating the rotating rod 42 and fixing it with the fastener, it is easier to adjust the position of the laptop screen, thereby reducing the situation where the screen cannot be seen clearly due to the person lying on the bed 1 or due to the light. This is beneficial for people who want to work but are injured and unable to move to work better on the nursing bed.

[0045] The position of the tray 4 is adjusted by driving the rotating rod 42, and then the fixed rod 52 on the pushing disc 51 is inserted into the locking groove 31 by pushing the pushing disc 51, and the pushing disc 51 abuts against the opening of the locking groove 31, thereby locking the rotating rod 42 and preventing it from rotating. This ensures that the rotating rod 42 is stable in the appropriate position, and thus the tray 4 is also stable in the appropriate position. This is beneficial for adjusting the tray 4 to the appropriate position and reduces the possibility of the rotating rod 42 rotating due to insufficient friction between the fixing component and the rotating rod 42. Insufficient friction between the fixing component and the rotating rod 42 can cause the rotating rod 42 to rotate, which in turn can cause the tray 4 to rotate and the laptop placed on the tray 4 to fall. This helps reduce the possibility of accidental damage to the laptop during the use of the care bed and improves the stability of the tray 4.

[0046] Through the arrangement of the load-bearing column 54, supporting ring 56, fixing ring 57, and stabilizing ring 58, the load-bearing column 54 and the crossbar 53 are integrated. When the load-bearing column 54 is under stress, it can distribute the force it receives to the crossbar 53 through the supporting ring 56, allowing the load-bearing column 54 and the crossbar 53 to jointly bear the force applied to the load-bearing column 54. Furthermore, the fixing ring 57 further reduces the force exerted by the load-bearing column 54 on the crossbar 53. Simultaneously, when the crossbar 53 is under stress, it can distribute the force it receives to the load-bearing column 54 through the supporting ring 56, allowing the crossbar 53 and the load-bearing column 54 to jointly bear the force applied to the crossbar 53. Furthermore, the stabilizing ring 58 further reduces the force exerted by the crossbar 53 on the load-bearing column 54. The combined action of the supporting ring 56, fixing ring 57, and stabilizing ring 58 ensures that the crossbar 53 and the load-bearing column can mutually bear the force. The force borne by the fixed rod 52 itself makes the connection between the fixed rod 52 and the push rod more stable, and also reduces the force exerted on each other by the support ring 56, making the fixed rod 52 more stable as a whole. In addition, the fixed ring 57 and the stabilizing ring 58 each form a stable triangular support structure, making the connection between the support ring 56 and the load-bearing column 54 and the crossbar 53 more stable. Furthermore, since the length of the load-bearing column 54 is shorter than the length of the crossbar 53, when the fixed rod 52 is subjected to force, the moment of the load-bearing column 54 is smaller than that of the crossbar 53, so the force on the load-bearing column 54 is smaller than that on the crossbar 53. Moreover, since the load-bearing column 54 shares the force on the crossbar 53, the radius of the fixed rod 52 can be made smaller, thereby improving the adjustment accuracy of the support plate 4, and the connection between the fixed rod 52 and the push disc 51 is less likely to break.

[0047] The placement of the mounting slot 41 ensures that after adjusting the tilt of the tray 4 and the desktop 3, the desktop 3 still has space for storing an external keyboard for a laptop, which helps to enhance the functionality of the caregiver table 2.

[0048] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
