[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Example 1
[0025] Reference Figure 1 This is the first embodiment of the present utility model. This embodiment provides a foldable barrier-free stair handrail device for ships, which can achieve the effect of sliding up and down the stairs along the original handrail. It includes a sliding member 100, a rotating shaft 200 and a handrail 300.
[0026] Specifically, the sliding component 100 includes a first mounting rod 101, a second mounting rod 102, and a bolt 103. The first mounting rod 101 and the second mounting rod 102 are fixed by the bolt 103, and the two ends of the first mounting rod 101 and the second mounting rod 102 are slidably engaged with the original handrail. The rotating shaft 200 is fixedly disposed on one side of the sliding component 100. The handrail 300 is rotatably engaged with the two ends of the rotating shaft 200.
[0027] Furthermore, the first mounting rod 101 and the second mounting rod 102 include latches 105 fixedly disposed at both ends of the connecting rod 104. The latches 105 are semi-circular in shape, and the first mounting rod 101 and the second mounting rod 102 are arranged opposite to each other. The sliding member 100 slides with the original handrail through the latches 105. The first mounting rod 101 and the second mounting rod 102 have the same structure. The two connecting rods 104 are tightly fitted together, and four latches 105 are provided, arranged in pairs opposite to each other. When the latches 105 are tightly fitted together, a circular through hole is formed in the middle. The circular through hole cooperates with the original handrail, so that the upper and lower ends of the sliding member 100 can slide along the original handrail.
[0028] Four bolts 103 are provided and are respectively located at both ends of the connecting rod 104. Fixing holes 104a are respectively provided at both ends of the connecting rod 104, and the bolts 103 engage with the fixing holes 104a. The fixing holes 104a are formed on the connecting rod 104. By screwing the bolts 103 into the fixing holes 104a, the first mounting rod 101 and the second mounting rod 102 can be pressed and fixed. After the first mounting rod 101 and the second mounting rod 102 are installed, the round holes at both ends will not press the original handrail firmly, so the sliding member 100 can slide along the original handrail.
[0029] When using the handrail 300, the elderly slide the handrail 300 to the corresponding position for each step they go up until they reach the end of the stairs. Then, rotate the handrail 300 forward along the rotating axis 200 until the handrail 300 is parallel to the original handrail, and fold it up for storage to avoid taking up space, helping users to go up or down the stairs smoothly.
[0030] In summary, the use of the sliding component 100 allows elderly people to slide the handrail while climbing stairs, enhancing support and providing convenience for them.
[0031] Example 2
[0032] Reference Figures 2-3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a foldable barrier-free stair handrail device for ships, which can achieve the effect of rotating and folding for storage. It includes a sliding member 100, a rotating shaft 200 and a handrail 300.
[0033] Specifically, the rotating shaft 200 is fixedly mounted on the side of the sliding member 100 away from the original handrail, and the extension direction of the rotating shaft 200 is consistent with the extension direction of the sliding member 100. The two ends of the handrail 300 are rotatably connected to the two ends of the rotating shaft 200 respectively.
[0034] Furthermore, a baffle is fixedly installed on one side of the rotating shaft 200, so that the handrail 300 can only rotate 90° to the other side. When the handrail 300 provides support to the elderly, the elderly apply a pulling force to the handrail 300. Due to the effect of the baffle, the handrail 300 will not rotate or sway when providing support to the elderly. When the elderly need to move the handrail 300, they only need to push the sliding part 100 upward along the original handrail to reach the next position, and then grab the handrail 300 for leverage, thus reaching the top of the stairs step by step.
[0035] The handrail 300 is also fixedly equipped with a reinforcing rod 301. The reinforcing rod 301 is arc-shaped. The reinforcing rod 301 is fixedly installed inside the handrail 300, enhancing the support of the handrail 300.
[0036] Preferably, the handrail 300 is U-shaped, which can provide more stable support.
[0037] When in use, the handrail 300 is perpendicular to the original handrail and will not rotate. The elderly grab the handrail 300 to go up the stairs. With each step, they push the slider 100 to the next target position, repeating the cycle. After use, the handrail 300 is rotated to a position parallel to the original handrail and folded up for storage to avoid blocking other people's passage on the stairs.
[0038] In summary, the use of the rotating shaft 200 and the armrest 300 allows the armrest 300 to be rotated and folded for storage when not in use, saving space and making operation simple and safe.
[0039] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values (e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.
