Technical Field

[0001] This utility model specifically relates to a foldable bedside handrail. Background Technology

[0002] Traditional bedside armrests are mostly fixed structures that cannot be folded after installation, taking up space even when not in use and affecting passage and layout around the bed. Furthermore, these armrests typically lack height adjustment, making them unsuitable for different bed sizes or mattress thicknesses, thus limiting their applicability. In addition, some foldable armrests have poorly designed locking mechanisms, resulting in complex operation and insecure locking, affecting safety and convenience.

[0003] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a safer and more convenient foldable bedside handrail.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a foldable bedside armrest, including a mounting frame for connecting to a bed frame. A support frame, located on one side of the bed frame when connected, is attached to the mounting frame. An armrest frame is connected to the support frame, and the armrest frame is rotatably connected to the support frame, allowing it to rotate from an upright position to a folded, hanging position. A connection is provided between the armrest frame and the support frame.

[0007] There is a first locking structure that locks both the handrail and the armrest in use.

[0008] As described above, in the foldable bedside armrest, the support frame is slidably connected to the mounting frame in the vertical direction, allowing the support frame to move up and down to adjust the height of the armrest frame. A second locking structure is provided between the support frame and the mounting frame to lock the two together.

[0009] As described above, the first locking structure of the foldable bedside armrest includes a limiting plate connected to the support frame and a movable rod connected to the armrest frame. The movable rod is slidably connected to the armrest frame, allowing it to move between an unlocked position and a locked position. An elastic element is provided between the movable rod and the armrest frame, which can push the movable rod from the unlocked position to the locked position. The limiting plate is provided with a locking groove that can accommodate the movable rod and prevent the armrest frame from rotating when it is in use. When the movable rod is in the locked position, it is engaged in the locking groove. When the movable rod is in the unlocked position, it is disengaged from the locking groove.

[0010] As described above, the foldable bedside armrest has a guide slope on one side of the locking groove on the limiting plate, which can push the movable rod from the locked position to the unlocked position when the armrest frame is rotated from the folded state to the use state.

[0011] As described above, the foldable bedside armrest has two mounting seats connected to the armrest frame. Each mounting seat has a slotted hole, and the two ends of the movable rod are respectively inserted into the slotted holes of the two mounting seats, allowing the movable rod to slide relative to the armrest frame. The elastic element is connected between the mounting seat and the movable rod.

[0012] As described above, the foldable bedside armrest has two mounting sleeves on the mounting frame, and the support frame includes two support rods that pass through the mounting sleeves and can slide up and down. The second locking structure includes several first through holes opened on the support rods and distributed vertically, second through holes opened on the mounting sleeves, and a fixing member for passing through the first and second through holes to lock the support rods and the mounting frame.

[0013] As described above, the foldable bedside armrest has a fixing component including an arc-shaped portion for locking onto the outer wall of the mounting sleeve, and the inner side wall of the arc-shaped portion is provided with a locking rod for passing through the first and second through holes.

[0014] The foldable bedside armrest described above is formed by bending tubular components and includes mounting sections at both ends for connecting support frames and a handrail in the middle.

[0026] The utility model will be further described below with reference to the accompanying drawings:

[0027] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0028] This embodiment provides a foldable bedside armrest, such as Figure 1 As shown, this structure includes a mounting bracket 1 for connection to the bed frame A. In this embodiment, the mounting bracket 1 is inserted into the gap A3 between the bed body A1 and the mattress A2; of course, to adapt to actual application scenarios, the mounting bracket 1 can also be directly fixed to the bed body A1 by means of fasteners, thereby improving the flexibility and applicability of the installation method.

[0029] like Figures 2 to 5 As shown, the mounting frame 1 is connected to a support frame 2 located on one side of the bed frame A when it is connected to the bed frame A. The support frame 2 is connected to an armrest frame 3, which is rotatably connected to the support frame 2. Figure 2 As shown, the armrest 3 can rotate from the upright use state P1 to the folded down state P2 when it rotates, thus achieving function switching.

[0030] A first locking structure 4 is provided between the handrail frame 3 and the support frame 2 to lock the two when the handrail frame 3 is in use. In this way, the handrail frame 3 can be locked or unlocked by the first locking structure 4, thereby locking the handrail frame 3 in the use state, so that it stands upright to form a stable guardrail. When not in use, the handrail frame 3 can also be unlocked and lowered into a folded state, without affecting the movement of getting in and out of bed, thus improving the convenience of use and space utilization.

[0031] As a preferred embodiment, the support frame 2 is slidably connected to the mounting frame 1 in the vertical direction, allowing the support frame 2 to move up and down, thereby adjusting the height of the armrest frame 3. A second locking structure 5 is provided between the support frame 2 and the mounting frame 1 to lock the two together, further adjusting the height of the armrest frame 3 to accommodate beds of different sizes and mattresses of different thicknesses, thus further improving the versatility and adaptability of the device.

[0032] To be more specific, such as Figure 4 and Figure 5 As shown, the first locking structure 4 includes a limiting plate 22 connected to the support frame 2 and a movable rod 41 connected to the handrail frame 3. Figure 5 As shown, the movable rod 41 is slidably connected to the handrail frame 3, so that the movable rod 41 can move between the unlocked position Q2 and the locked position Q1.

[0033] Specifically, the handrail frame 3 is connected to two mounting seats 31, each with a slotted hole 311. The two ends of the movable rod 41 are inserted into the slotted holes 311 of the two mounting seats 31, allowing the movable rod 41 to slide relative to the handrail frame 3. An elastic element 42 connects the mounting seats 31 and the movable rod 41. In this embodiment, the elastic element 42 is a spring or tension spring. One end of the elastic element 42 is fixed to the mounting seat 31 by a screw, while the other end acts on the movable rod 41, providing it with a restoring force.

[0034] like Figure 4 and Figure 5 As shown, an elastic element 42 is provided between the movable rod 41 and the handrail frame 3, which can push the movable rod 41 from the unlocked position to the locked position. The limiting plate 22 is provided with a locking groove 221 that can accommodate the movable rod 41 and prevent the handrail frame 3 from rotating when it is in use. When the movable rod 41 is in the locked position, the movable rod 41 is engaged in the locking groove 221 to form a mechanical lock; when the movable rod 41 is in the unlocked position, the movable rod 41 is disengaged from the locking groove 221, and the handrail frame 3 can rotate freely.

[0035] When the handrail 3 is in use, the elastic element 42 pushes the movable rod 41 to automatically engage with the locking groove 221, thereby achieving a stable lock. When unlocking is required, simply manually move the movable rod 41 to the unlock position Q2 to release the lock. The operation is simple, safe and reliable.

[0036] In order for the handrail 3 to automatically engage with the locking slot 221 when rotating from the folded state to the usable state, such as... Figure 4 As shown, the limiting plate 22 has a guide slope 222 on one side of the locking groove 221, which can push the movable rod 41 from the locked position to the unlocked position when the handrail 3 is rotated from the folded state to the use state. When the handrail 3 is rotated from the folded state to the use state, the guide slope 222 first contacts and pushes the movable rod 41 to the unlocked position Q2. As the handrail 3 continues to rotate to the use position, after the movable rod 41 moves to the locking groove 221, the elastic element 42 pushes the movable rod 41 to automatically lock into the locking groove 221, completing the self-locking action and improving the user experience.

[0037] To be more specific, such as Figure 3 As shown, the mounting bracket 1 has two mounting sleeves 11, and the support frame 2 is a split structure, which includes two support rods 21 that pass through the mounting sleeves 11 and can slide up and down. Of course, the support frame 2 can also be a one-piece structure to meet different manufacturing process requirements.

[0038] The second locking structure 5 includes a plurality of first through holes 211 opened on the support rod 21 and distributed vertically, a second through hole 111 opened on the mounting sleeve 11, and a fixing member 51 for passing through the first through hole 211 and the second through hole 111 to lock the support rod 21 and the mounting bracket 1, thereby realizing the locking function after height adjustment.

[0039] As a preferred option, such as Figure 3 As shown, the fixing member 51 includes an arc-shaped part 511 for locking onto the outer wall of the mounting sleeve 11. The inner side wall of the arc-shaped part 511 is provided with a locking rod 512 for passing through the first through hole 211 and the second through hole 111, making the structure more compact and stable, while facilitating users to quickly complete height adjustment and locking operations.

[0040] As a preferred option, such as Figures 1 to 5 As shown, the handrail frame 3 comprises an integral structure formed by bending tubular components, including mounting sections 32 at both ends for connecting to the support frame 2, and a handrail arm 33 in the middle. The handrail arm 33 has an extension 34 protruding to one side formed by bending, thereby increasing the effective length and ergonomic performance of the handrail and improving grip comfort.

[0041] To further improve comfort and safety, the handrail 33 is fitted with a grip sleeve 35 for people to hold. The grip sleeve 35 can be made of soft plastic or silicone that can increase friction and have a cushioning effect. It is not only non-slip and durable, but also effectively relieves the user's discomfort during the gripping process. It is suitable for special groups such as the elderly and rehabilitation patients.

[0042] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
