Description

Technical Field

[0001] This application relates to the field of bedside handrail technology, and more particularly to a bedside handrail structure and a hospital bed having the bedside handrail. Background Technology

[0002] Currently, common bedside armrest designs on the market often use a parallelogram structure, which has some shortcomings. Especially for elderly people who need to sit up from a lying position with the help of the armrests, the specific angle formed by the vertical and horizontal bars of the parallelogram armrests does not perfectly match the natural grip angle of the human hand. Therefore, when the elderly try to grasp these armrests to help themselves sit up, they often find this action quite strenuous. Furthermore, due to the mismatched angles, the elderly are prone to slipping while gripping, which not only reduces comfort but may also pose a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing a bedside handrail structure and a hospital bed.

[0004] The technical solution of this application is implemented as follows:

[0005] In a first aspect, this application provides a bedside armrest structure, the bedside armrest structure comprising:

[0006] A first handrail component, comprising a continuous gripping section and a support section, wherein one end of the gripping section is rotatably connected to a mounting base and the other end is connected to the support section;

[0007] The second handrail component has a first end that is slidably connected to the mounting base in a preset direction, and the second end of the first handrail component is connected to the support section of the second handrail component by a locking component.

[0008] The locking component includes two mutually rotatable connecting rods, with the ends of the two connecting rods being respectively connected to: the second end connection of the first handrail component and the support section connection;

[0009] The locking element has a locking structure, which enables:

[0010] The two connecting rods are kept perpendicular or the two connecting rods are allowed to rotate coaxially;

[0011] The preset direction is the length direction of the mounting base;

[0012] The mounting base is also equipped with a plug plate, which is used to fix the mounting base to the bed.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following:

[0014] The inclined and curved grip sections allow elderly people in a lying position to easily sit up by grasping these parts. This inclined design conforms to the ergonomic angle of the hand, providing a comfortable gripping experience. After sitting up, when preparing to get out of bed, they can rely on the support sections for support, allowing them to get out of bed safely. This combination of grip and support sections makes the transition from gripping to support more natural and smooth, greatly improving the elderly's independent mobility, while also enhancing their sense of security and comfort.

[0030] Reference Figure 1 A bedside armrest structure, the bedside armrest structure including a mounting base 50:

[0031] The bedside armrest structure also includes: a first armrest component 10 and a second armrest component 20;

[0032] The first handrail component 10, specifically, includes a continuous gripping section 11 and a support section 12. One end of the gripping section 11 is rotatably connected to the mounting base 50, and the other end is connected to the support section 12.

[0033] Combination Figure 1 and Figure 8 As shown, the gripping section 11 is curved, with the end of the gripping section 11 connected to the mounting base 50 oriented perpendicularly to the orientation of the support section 12. The gripping section 11 faces the headboard, and the bedside armrest is installed near the headboard. When the bedside armrest is extended, if the user is in a lying position and wishes to sit up, the user's hands can easily grasp the gripping section 11 because it is designed with a slight curvature and bends towards the user. Subsequently, the user can pull the gripping section 11 towards their body, which helps the user sit up more easily. When it is necessary to get out of bed, the hands can be supported on the straight support section 12, which provides necessary assistance and stability for getting out of bed.

[0034] The first end of the second armrest component 20 is slidably connected to the mounting base 50 in a preset direction. The second end of the first armrest component 10 is connected to the support section 12 of the second armrest component 20 through the locking component 30. The preset direction is the length direction of the mounting base 50. Since the second armrest component 20 is in a vertical state, the curved gripping section 11 increases the height of the armrest and gives the bedside armrest a blocking function.

[0035] The locking member 30 includes two rotatable connecting rods, with the ends of the two connecting rods being respectively connected to the second end of the first handrail member 10 and the second end of the second handrail member 20.

[0036] Furthermore, a mounting plate 52 is also installed on the mounting base 50. The mounting plate 52 is used to fix the mounting base 50 to the bed, such as... Figure 8 As shown, the insert plate 52 has an L-shaped structure, with the shorter side installed on the mounting base 50 and the longer side installed on the bed frame. It should be noted that the bedside handrail is not only suitable for hospital beds; this product can also be installed on beds at home to help the elderly get in and out of bed.

[0037] When the bedside armrest is raised, such as Figure 1 As shown in the upper part, the second handrail 20 is in a vertical position, which can provide a shield for the edge of the bed to prevent the patient from falling. When the patient needs to get out of bed, the first end of the second handrail 20 moves towards the first handrail 10, the two connecting rods rotate relative to each other, and the second end of the first handrail 10 rotates downwards, as shown in the upper part. Figure 2The lower part is shown, which lowers the height of the handrail to make it easier for patients to get into bed.

[0038] Based on the above structure, the locking member 30 has a locking structure 33, which can keep the orientation of the two connecting rods perpendicular, that is, when the bedside armrest is raised, or allow the two connecting rods to rotate coaxially, that is, when the bedside armrest needs to be lowered.

[0039] Furthermore, the two connecting rods include a first connecting rod 31 and a second connecting rod 32, wherein the end of the first connecting rod 31 away from the second connecting rod 32 is connected to the second end of the first handrail member 10, and the end of the second connecting rod 32 away from the first connecting rod 31 is connected to the second end of the second handrail member 20, thus forming a complete connecting rod system.

[0040] Specifically, the locking structure 33 includes:

[0041] Locking pin 331 is fixedly installed at the pivot of the second connecting rod 32. The position of locking pin 331 changes as the second connecting rod 32 rotates. Figure 6 As shown;

[0042] The locking disc 332 has a locking hole 3321. It is worth noting that the opening direction of the locking hole 3321 is perpendicular to the orientation of the first connecting rod 31. The locking disc 332 is slidably mounted on the pivot of the first connecting rod 31 so that the end of the locking pin 331 away from the second connecting rod 32 can extend into or out of the locking hole 3321. When the locking pin 331 extends into the locking hole 3321, the orientations of the first connecting rod 31 and the second connecting rod 32 remain perpendicular to each other. When the locking pin 331 extends out of the locking hole 3321, the first connecting rod 31 and the second connecting rod 32 can rotate freely coaxially.

[0043] Specific references Figure 6 When the locking pin 331 is inserted into the lock hole 3321, the position of the locking disc 332 is as follows: Figure 6 As shown in the left half, since the locking pin 331 is fixed to the second connecting rod 32, the first connecting rod 31 and the second connecting rod 32 cannot rotate relative to each other. When it is necessary for the first connecting rod 31 and the second connecting rod 32 to rotate, the locking disc 332 is moved, causing the lock hole 3321 to separate from the locking pin 331, as shown. Figure 6 As shown in the right half, the position of the locking pin 331 is no longer restricted, and the first connecting rod 31 and the second connecting rod 32 can rotate freely.

[0044] The locking structure 33 further includes a reset component for maintaining the position of the locking disc 332. The reset component includes a reset spring 333, which is installed in the pivot of the first connecting rod 31. One end of the reset spring 333 abuts against the locking disc 332, and the other end abuts against the inner wall of the first connecting rod 31. When the locking disc 332 is not pushed by an external force, the reset spring 333 extends, allowing the locking pin 331 to extend into the lock hole 3321 and maintain its position. When the locking disc 332 needs to move, it is pushed, causing the reset spring 333 to compress, allowing the first connecting rod 31 and the second connecting rod 32 to rotate freely. It should be noted that when the first connecting rod 31 and the second connecting rod 32 return to a mutually perpendicular state, the position of the lock hole 3321 corresponds to the position of the locking pin 331. At this time, the reset spring 333 extends, pushing the locking disc 332, causing the locking pin 331 to automatically engage in the lock hole 3321, so that the handrail returns to the covered state.

[0045] Based on the above structure, the locking structure 33 further includes an unlocking button disk 334, which is telescopically mounted on the surface of the pivot of the second connecting rod 32. A push rod 3342 is provided on the side of the unlocking button disk 334 near the first connecting rod 31. The end of the push rod 3342 away from the unlocking button disk 334 passes through the second connecting rod 32 and abuts against the locking disk 332. The user can press or release the unlocking button disk 334 with the cooperation of the return spring 333 to change the position of the locking disk 332, thereby fixing or rotating the first connecting rod 31 and the second connecting rod 32.

[0046] Furthermore, the unlock button disk 334 has a guide piece 3341 on the side near the first connecting rod 31, with one end of the guide piece 3341 extending out of the outer peripheral surface of the unlock button disk 334; a guide groove 321 is provided on the second connecting rod 32, and the guide piece 3341 is movably embedded in the guide groove 321 to limit the movement of the unlock button disk 334 and prevent it from falling off.

[0047] Based on the further improvement of the above structure, a sliding groove 51 is also provided on the surface of the mounting base 50. A transition block 511 is movably installed in the sliding groove 51. The first end of the second handrail member 20 is rotatably connected to the transition block 511 so that the first end of the second handrail member 20 can move back and forth on the mounting base 50.
