Description

Technical Field

[0001] This utility model relates to a safety protection device, specifically a height-adjustable and foldable safety handrail. Background Technology

[0002] Safety handrails are a common safety protection device. Their main function is to provide users with a handrail to help them stand or get up. They play a good protective role in the daily life of the elderly, disabled and other people with limited mobility. They are most commonly used in bathroom environments, such as on the side of the toilet or in the shower room.

[0003] Chinese utility model patent with authorization announcement number CN 223232624 U discloses a safety handrail for bathroom use, including a mounting bracket and a handrail body. The mounting bracket consists of a mounting plate and two fixing frames, both of which are fixedly installed on one side of the mounting plate. The handrail body consists of a U-shaped tube, an adjusting tube, a connecting tube, and a rotating tube. One end of the U-shaped tube is fixedly connected to the adjusting tube and the connecting tube in sequence. The connecting tube is fixedly connected to the middle of the rotating tube to form a T-shaped structure.

[0004] The aforementioned safety handrails utilize a unique locking mechanism to achieve flexible angle adjustment and secure locking, meeting diverse usage needs. However, these handrails lack height adjustment, making them unsuitable for users of varying heights. If height mismatch issues arise, secondary drilling and reinstallation in the wall are required, which is not only cumbersome but may also damage the wall structure. This limitation is particularly pronounced in public places such as nursing homes and hospitals, leading to handrails in some public facilities becoming merely decorative. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a height-adjustable and foldable safety handrail that can be adjusted in height to meet the needs of users of different heights, and has the advantages of convenient adjustment and strong adaptability.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a height-adjustable and foldable safety handrail, comprising an installation unit, a handrail bar and a support bar, wherein the installation unit comprises an installation seat and a slide seat, the slide seat is slidably connected to the installation seat, and a first locking unit is provided between the slide seat and the installation seat; The handrail is rotatably connected to the slide, and the support rod is rotatably connected to the handrail. The rotation axis of the handrail relative to the slide is perpendicular to the sliding direction of the slide, and the rotation axis of the handrail relative to the slide is parallel to the rotation axis of the support rod relative to the handrail. The length of the support rod is adjustable.

[0007] During installation, the mounting base is used to connect and fix it to a wall or other foundation, and the support rod is located under the handrail. In use, the handrail is set horizontally for the operator to support it, while the support rod is set vertically to contact the ground and provide support. When not in use, the handrail rotates upwards, and the support rod rotates relative to the handrail to adjust and fold, reducing space occupation.

[0008] During use, the first locking unit is in the locked state. When the installation height needs to be adjusted, the first locking unit is unlocked, and the height of the handrail can be adjusted by sliding the slide block. After adjustment, the first locking unit can be locked again, making the adjustment method convenient. To ensure a proper installation angle for the handrail, the length of the support rod can be adjusted accordingly.

[0009] Compared with existing handrails, the safety handrail of this application can be adjusted in height to meet the needs of users of different heights. It also has a folding function for more flexible use and has the advantages of convenient adjustment and strong adaptability.

[0010] Preferably, the mounting base is provided with a straight slide rail, and the slide block is provided with a slide groove, and the slide block is connected to the mounting base through the slide groove and the slide rail.

[0011] Preferably, the mounting base is provided with a plurality of locking holes, each of the locking holes being distributed along the sliding direction of the slide relative to the mounting base; the first locking unit includes a locking pin disposed on the slide, the locking pin being matched with the locking hole.

[0012] When the slide is adjusted to different heights, the locking pin matches and limits the locking hole at different positions, achieving reliable and stable locking at different heights.

[0015] Preferably, a damping unit is provided between the handrail and the clamp, or between the handrail and the central axis.

[0016] The damping unit creates a certain rotational resistance between the handrail and the slide. Under normal adjustment, appropriate resistance can improve the user's feel. In the folded state, the rotational resistance can prevent the handrail from falling, keeping it folded.

[0017] Preferably, an intermediate seat is provided between the handrail and the support rod, and a slot is provided on the intermediate seat. The slot is open in the direction facing the slide groove and in the direction away from the handrail, and a stop is provided on the side of the slot away from the slide. The intermediate seat is fixedly connected to the handrail, and one end of the support rod is inserted into the slot and rotatably connected to the intermediate seat.

[0018] When in use, the support rod is lowered, and the stop block limits the maximum angle of the support rod relative to the handrail. When the handrail is folded up, the support rod naturally rotates relative to the handrail under the influence of gravity, reducing the angle of the support rod relative to the handrail and ultimately achieving folding.

[0019] Preferably, the support rod includes a main rod and a telescopic rod, one end of the main rod is connected to the handrail and the other end is connected to the telescopic rod; the telescopic rod can be adjusted relative to the main rod along the length direction, and a second locking unit is provided between the main rod and the telescopic rod.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0024] like Figures 1-4 As shown, a height-adjustable and foldable safety handrail includes a mounting unit, a handrail bar 3, and a support bar 4. The mounting unit includes a mounting base 1 and a sliding base 2, wherein the sliding base 2 is slidably connected to the mounting base 1. Figure 5 As shown, a first locking unit 5 is provided between the slide 2 and the mounting base 1.

[0025] Specifically, such as Figure 5 As shown, the mounting base 1 is provided with a straight slide rail, and the slide block 2 is provided with a slide groove 24. The slide block 2 is connected to the mounting base 1 through the slide groove 24 and the slide rail.

[0026] Furthermore, the mounting base 1 is provided with a plurality of locking holes, each of which is distributed along the sliding direction of the slide 2 relative to the mounting base 1. The first locking unit 5 includes a locking pin disposed on the slide 2, the locking pin matching the locking hole. When the slide 2 is adjusted to different heights, the locking pin matches and limits the locking hole at different positions, thereby achieving reliable and stable locking at different heights.

[0027] like Figure 5 As shown, the handrail 3 is rotatably connected to the slide 2, and the support rod 4 is rotatably connected to the handrail 3. The rotation axis of the handrail 3 relative to the slide 2 is perpendicular to the sliding direction of the slide 2, and the rotation axis of the handrail 3 relative to the slide 2 is parallel to the rotation axis of the support rod 4 relative to the handrail 3.

[0028] like Figure 5 As shown, specifically, the slide 2 is provided with two parallel clamping plates 22, and one end of the handrail 3 is inserted between the two clamping plates 22. It also includes a central shaft 23, which passes through the clamping plates 22 and the handrail 3.

[0029] like Figure 5As shown, a damping unit 21 is further provided between the handrail 3 and the clamp 22, or between the handrail 3 and the central shaft 23. The damping unit 21 can generate a certain rotational resistance between the handrail 3 and the slide 2. During normal adjustment, appropriate resistance can improve the user's feel. In the folded state, the rotational resistance can prevent the handrail 3 from falling, keeping the handrail 3 in a folded state.

[0030] As one specific implementation, the handrail 3 is provided with an anti-slip sleeve to improve the comfort and safety of the user when holding it.

[0031] Specifically, such as Figure 6 As shown, an intermediate seat 6 is provided between the handrail 3 and the support rod 4. The intermediate seat 6 has a slot, which is open in the direction facing the slide groove 24 and in the direction away from the handrail 3. A stop block 61 is provided on the side of the slot away from the slide 2. The intermediate seat 6 is fixedly connected to the handrail 3, and one end of the support rod 4 is inserted into the slot and rotatably connected to the intermediate seat 6.

[0032] When in use, the support rod 4 is lowered, and the stop block 61 can limit the maximum angle of the support rod 4 relative to the handrail 3. When the handrail 3 is retracted, the support rod 4 naturally rotates relative to the handrail 3 under the action of gravity, reducing the angle of the support rod 4 relative to the handrail 3, and finally achieving folding.

[0033] The length of the support rod 4 is adjustable. Specifically, for example... Figures 7-9 As shown, the support rod 4 includes a main rod 41 and a telescopic rod 42. One end of the main rod 41 is connected to the handrail 3, and the other end is connected to the telescopic rod 42. The telescopic rod 42 can be adjusted relative to the main rod 41 along its length, and a second locking unit is provided between the main rod 41 and the telescopic rod 42.

[0034] Furthermore, such as Figures 7-9 As shown, one end of the telescopic rod 42 is provided with a insertion groove, and the end of the main rod 41 facing away from the handrail 3 is inserted into the insertion groove. The second locking unit includes a locking sleeve 43, which is sleeved on the main rod 41. A pressure block 46 is provided inside the locking sleeve 43, and an operating unit 44 is provided on the locking sleeve 43. The operating unit 44 is connected to the pressure block 46 and is used to adjust the pressure block 46 in a direction perpendicular to the main rod 41; one end of the telescopic rod 42 is fixedly connected to the locking sleeve 43.

[0035] As a specific implementation method, such as Figures 7-9 As shown, the end of the support rod 4 away from the main rod 41 is provided with an elastic pad 45. The elastic element can play the role of buffering protection and reducing impact noise.

[0036] like Figure 3and Figure 4 As shown, during installation, the mounting base 1 is used to connect and fix it to the wall or other foundation, and the support rod 4 is located under the handrail 3. Figure 3 As shown, in use, the handrail 3 is horizontally positioned for the operator's support, while the support rod 4 is vertically positioned to contact the ground and provide support for the handrail 3. Figure 4 As shown, when not in use, the handrail 3 rotates upward, and at the same time, the support rod 4 rotates relative to the handrail 3 to adjust and adapt, thus achieving folding and reducing space occupation.

[0037] During use, the first locking unit 5 is in a locked state. When the installation height needs to be adjusted, the first locking unit 5 is unlocked, and the height of the handrail 3 can be adjusted by sliding the slide block 2. After adjustment, the first locking unit 5 can be locked again, making the adjustment method convenient. To ensure that the installation angle of the handrail 3 is appropriate, the length of the support rod 4 can be adjusted to accommodate it.

[0038] Compared with existing handrails, the safety handrail of this application can be adjusted in height to meet the needs of users of different heights. It also has a folding function for more flexible use and has the advantages of convenient adjustment and strong adaptability.

[0039] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
