Description

Technical Field

[0001] This utility model relates to the field of nursing beds, and more specifically, to a segmented lift guardrail and a nursing bed. Background Technology

[0002] With an aging population, the demand for care for disabled, bedridden elderly people is increasing dramatically. The safety and comfort of nursing beds have become the focus of the industry, and the function and structure of guardrails, as a core component of nursing beds, are of great concern to those skilled in the art and consumers alike.

[0003] Current nursing beds all use fully enclosed guardrails. While traditional fully enclosed guardrails can prevent falls, 83% of elderly people feel oppressed, which affects their independent movement and mental well-being. They are also cumbersome and laborious for caregivers. Research shows that bedridden individuals have different protection needs in different scenarios: 100% protection is needed at night, while the upper body needs to be exposed during daytime meals and rehabilitation, and only partial protection is required during nursing care. Existing liftable guardrails cannot meet these needs.

[0004] How to develop a segmented lifting guardrail system that is easy to operate and use is the problem we need to solve. Utility Model Content

[0005] The main purpose of this application is to provide a segmented lifting guardrail and nursing bed, which adopts a modular design and the guardrail is segmented, allowing for the operation of parts of the guardrail as needed.

[0006] To achieve the above objectives, in a first aspect, this application provides a segmented pull-up guardrail installed on both sides of the headboard and footboard of a nursing bed, with at least two on each side. Each segmented pull-up guardrail includes a fixed outer tube fixedly connected to the nursing bed on both sides, a sliding column slidably disposed perpendicularly to the fixed outer tube, and a handrail fixedly connected to the upper part of the sliding columns on both sides. A locking mechanism is provided between the sliding column and the fixed outer tube to lock the two in at least one working position. The locking mechanism includes a linkage member rotatably connected to the sliding column, a hook-shaped component disposed at the lower end of the linkage member, and an operating component disposed at the other end of the linkage member. A slot is provided on the fixed outer tube to cooperate with the hook-shaped component, and an elastic element is provided between the linkage member and the sliding column.

[0029] In addition, the term "multiple" should mean two or more.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-5 As shown, a segmented lifting guardrail and nursing bed 1 are installed on both sides of the headboard 2 and footboard 3 of the nursing bed 1, with at least two guardrails on each side. The specific number of guardrails is selected according to the model of the nursing bed 1 and the size of the guardrails, but there are no less than two on each side, thereby realizing segmented lifting operation.

[0032] Its specific structure is as follows:

[0033] Each of the segmented lifting guardrails includes a fixed outer tube 4 fixedly connected to the nursing bed 1 on both sides, a sliding column 5 slidably arranged perpendicularly to the fixed outer tube 4, and a handrail 6 fixedly connected to the upper part of the sliding column 5 on both sides. A locking mechanism is provided between the sliding column 5 and the fixed outer tube 4 to lock the two in at least one working position. The locking mechanism includes a linkage 7 rotatably connected to the sliding column 5, a hook-shaped component 16 provided at the lower end of the linkage 7, and an operating component 10 provided at the other end of the linkage 7. The fixed outer tube 4 is provided with a slot 8 that cooperates with the hook-shaped component 16. An elastic component 9 is provided between the linkage 7 and the sliding column 5.

[0034] During operation, pressing the operating component 10 causes the linkage component 7 to rotate. At this time, the hook-shaped component disengages from the slot 8, and then pressing the handrail 6 allows the sliding column 5 to slide downward relative to the fixed outer sleeve 4, thus lowering the guardrail. When it is necessary to raise the guardrail, simply lift the handrail 6 upward, thereby causing the sliding column 5 to slide upward. When the hook-shaped component 16 is aligned with the slot 8, it is locked into the slot 8 under the action of the elastic component 9. The operation is convenient. The elastic component 9 is preferably a spring sheet. In addition, the locking mechanism is built-in, that is, it is set in the inner cavity of the sliding column 5, making the overall guardrail aesthetically pleasing.

[0035] To reduce operating noise and provide a limiting and guiding function for the sliding column 5, a silent limiter 11 is fixedly installed at the lower end of the sliding column 5. A limiting structure is provided between the silent limiter 11 and the fixed outer sleeve 4. Specifically, the limiting structure includes a limiting groove formed in the inner wall of the fixed outer sleeve 4 and a limiting protrusion fixedly installed on the silent limiter 11 that cooperates with the limiting groove. The limiting groove extends along the sliding direction of the sliding column 5. By setting the silent limiter 11, not only can a good limiting function be achieved, but the up and down movement of the guardrail is also quiet and smooth.

[0036] For ease of connection, a metal connector 12 is fixedly installed at the bottom of the handrail 6. The linkage 7 is rotatably connected to the metal connector 12. The sliding column 5 is fixedly installed relative to the metal connector 12. It should be noted that the handrail 6 is made of solid wood, with a rounded shape and a thickness that conforms to the optimal thickness for human grip. The sliding column 5 is made of metal, hence the metal connector 12 is installed on the handrail 6 for easy installation. To ensure a good pressing feel, the operating component 10 is a plastic button, which is integrated with the linkage 7 and the button via the irregularly shaped metal connector 12. When the button on the handrail 6 is lightly touched, the linkage 7 begins to rotate, and the hook-shaped component 16 retracts into the sliding column 5, realizing the extension and retraction of the guardrail. The hook-shaped component 16 has an arc-shaped upper side and a flat lower opening, allowing the guardrail to be limited when it rises to a certain extent.

[0037] In order to adjust the installation height of the guardrail as needed, the fixed outer sleeve 4 is provided with a number of mounting holes 13 along its height direction.

[0038] To ensure overall strength, at least one fixed support connecting rod 15 is fixedly installed between the two fixed outer sleeves 4. In this embodiment, there are two fixed support connecting rods 15. In addition, to improve aesthetics, a decorative plate 14 is fixedly installed between the two sliding columns 5.

[0039] In order to enable simultaneous unlocking of both sides by pressing on one side, a linkage mechanism is provided between the two operating components 10. The linkage mechanism includes a linkage rod with one end rotatably connected to one of the operating components 10, and the other end of the linkage rod rotatably connected to the other operating component 10.

[0040] like Figure 6 As shown, a nursing bed 1 includes a bed body and the aforementioned segmented pull-up guardrails installed on the bed body.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
