Description

Technical Field

[0001] This utility model relates to the field of building accessibility assistance technology, and in particular to a step device with extension and lifting functions. Background Technology

[0002] Currently, solutions for navigating indoor and outdoor elevation differences can be mainly divided into three categories, with the following specific structures, functions, and application scenarios:

[0003] (1) Fixed steps

[0004] Structural composition: It is made of concrete or metal, usually with multiple steps, no additional moving parts, and the appearance is mostly a single material (such as concrete or stone). Its integration with the building facade depends on the later decoration.

[0005] Working method: It only serves as a fixed carrier for pedestrians to pass through, and its height or shape cannot be adjusted, lacking barrier-free passage function;

[0006] Application scenarios: Widely used at the entrances of various buildings, but requires an independent barrier-free access (such as a ramp) or an additional space for the lifting platform to meet the needs of wheelchair users.

[0007] (2) Independent barrier-free lifting platform

[0008] Structural composition: It consists of a metal support platform, fixed brackets, manual and electric drive modules. It needs to be fixed to the ground separately. There is no uniform appearance covering on the outside. It is mostly an exposed metal structure.

[0009] Operating method: Before use, the support frame needs to be manually unfolded and the lifting height adjusted (some parts need to be manually locked). After use, the support frame needs to be manually stored. The lifting parts are exposed for a long time.

[0010] Application scenarios: Only applicable to building entrances with ample space (requires ≥1.5㎡ of dedicated installation space), with low integration of appearance with the building environment, easily forming an "obtrusive addition".

[0011] To address the core deficiencies of existing technologies, this utility model aims to achieve four major goals: "space adaptability, efficiency improvement, functional compatibility, and unified appearance," and specifically solves the following technical problems:

[0012] (1) The problem of limited building space preventing the installation of compliant barrier-free ramps;

[0013] (2) Ordinary steps do not have the compatibility and flexible switching between the two access modes of ordinary access and barrier-free access. Utility Model Content

[0014] Based on the above analysis, the present invention aims to provide a step device with extension and lifting functions to solve the problems of ordinary steps lacking coupling compatibility with barrier-free access functions and the difficulty in compliant installation of barrier-free ramps in buildings with limited space.

[0015] The objective of this utility model is mainly achieved through the following technical solutions:

[0016] A step device with extension and lifting functions includes a step device, a cavity, a baffle assembly, and an electronic control assembly; the cavity is disposed inside the step device, and the baffle assembly can be housed in the cavity; the electronic control assembly is used to control the step device to switch between a normal step passage mode and an accessible passage mode.

[0017] Furthermore, in the normal stair passage mode, the baffle assembly is completely housed within the cavity.

[0018] Furthermore, in the barrier-free access mode, the electronic control component drives the baffle assembly to extend and unfold from the step device, and raise it to form a horizontal passage flush with the highest step.

[0019] Furthermore, the step device includes a structural frame and a telescopic opening; the telescopic opening is located on the middle step facade of the step device.

[0020] Furthermore, the cavity is a cuboid cavity used to accommodate the baffle assembly and the electronic control assembly.

[0021] Furthermore, the baffle assembly includes a first damping hinge, a first baffle, a second baffle, a second damping hinge, and a third baffle.

[0022] Furthermore, the first baffle is hinged to the third baffle via the first damping hinge.

[0023] Furthermore, the second baffle is hinged to the third baffle via the second damping hinge.

[0024] Furthermore, both the first damping hinge and the second damping hinge are equipped with damping, and the first baffle and the second baffle can rotate between 0° and 180° along the hinge center axis and remain stationary.

[0025] Furthermore, the electronic control component includes a button assembly and a control device; the button assembly is disposed on the step surface of the step device; the control device is disposed in the cavity, and the control device is electrically connected to the button assembly, the first damping hinge, and the second damping hinge respectively.

[0026] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0027] (1) The step device of this utility model addresses the problem that the building space is limited and it is impossible to install a compliant barrier-free ramp. Through the structural design of being "retractable" and "expandable", it replaces the traditional indoor and outdoor height difference steps or part of the step structure. It does not require additional modification of the original building foundation, avoids damage to the building structure, and reduces construction difficulty and cost.

[0028] (2) The step device of this utility model controls the extension, unfolding and lifting of the baffle assembly through the electronic control component, realizing the two-way flexible switching between ordinary step passage and barrier-free passage. It not only meets the daily passage needs of normal pedestrians, but also provides a safe and smooth barrier-free passage for people with mobility impairments (such as wheelchair users and the elderly), adapting to the needs of multiple scenarios.

[0029] (3) The step device of this utility model, through the design of integrating the appearance with the building, in the normal mode, the baffle component is completely stored in the cavity, the appearance of the device is consistent with the original style of the building, and there are no protruding exposed parts, which ensures the overall aesthetics and harmony of the building.

[0030] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the description and accompanying drawings, which are particularly pointed out. Attached Figure Description

Detailed Implementation

[0038] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0039] Example 1

[0040] A specific embodiment of this utility model discloses an accessible passage device, such as... Figure 1 , Figure 2 and Figure 4 As shown, the barrier-free access device includes a step device 1, a cavity 2, a baffle assembly 4, an outer surface component 5, and an electronic control component 6 (not shown in the figure). The cavity 2 is located inside the step device 1, the baffle assembly 4 is located in the cavity 2, the outer surface component 5 covers the outer surface of the step device 1 and leaves space for the opening of the cavity 2, and the electronic control component 6 has a built-in action logic program for controlling the switching of the access mode of the step device.

[0041] In this embodiment, in order to be applicable to application scenarios that switch between normal passage and barrier-free passage, such as... Figures 1 to 4 As shown, the step device 1 includes a structural frame 11 and a telescopic opening 12. The structural frame 11 is the overall structural frame of the step device 1. Expansion bolts are provided on the bottom and sides of the structural frame 11 for fixing to the ground and wall. The step device 1 is made of concrete (e.g., C30 concrete), and the structural frame 11 is a steel frame structure (e.g., galvanized square steel). The telescopic opening 12 is located on the middle step facade of the step device 1 and faces the outside.

[0042] The middle step of the step device 1 has a cavity 2 inside. The cavity 2 is a cuboid cavity that can accommodate the lifting component 3, the baffle component 4 and the electrical control component 6. The cavity 2 is lined with a stainless steel plate.

[0043] The step device 1 also includes a lifting assembly 3, which is disposed in the cavity 2, such as... Figures 2 to 4As shown, the lifting assembly 3 includes a receiving frame 31, a first rotating shaft 32, a slide rail 33, a push rod 34, a second rotating shaft 35, and a rotating assembly 36. The receiving frame 31 is disposed inside the cavity 2 and its size is adapted to the cavity 2. The slide rail 33 is disposed at the bottom of the receiving frame 31. The push rod 34 is disposed along the outside of the slide rail 33 and is parallel to the slide rail 33. The rotating assembly 36 is disposed at the end of the slide rail 33 and is fixedly connected to the slide rail 33. The push rod 34 is provided with a gear meshing surface. The rotating assembly 36 includes a rotating shaft 361 and a rotating wheel 362. The rotating shaft 361 and the rotating wheel 362 are fixedly connected. The rotating wheel 362 is provided with end face teeth. The rotating wheel 362 and the push rod 34 form a gear mesh. The first rotating shaft 32 and the second rotating shaft 35 are respectively disposed at the end of the push rod 34. The push rod 34 is hinged to the slide rail 33 through the first rotating shaft 32. The hinge of the push rod 34 and the first rotating shaft 32 is provided with damping.

[0044] The baffle assembly 4 is mounted on the lifting assembly 3, such as Figures 2 to 4 As shown, the baffle assembly 4 includes a first damping hinge 41, a first baffle 42, a second baffle 43, a second damping hinge 44, and a third baffle 45. The third baffle 45 is disposed inside the push rod 34. The front end of the third baffle 45 is hinged to the push rod 34 via a second rotating shaft 35. The hinge between the third baffle 45 and the second rotating shaft 35 is damped. The second rotating shaft 35 drives the third baffle 45 to rotate and remain stationary. The first baffle 42 is hinged to the third baffle 45 via the first damping hinge 41, and the second baffle 43 is hinged to the third baffle 45 via the second damping hinge 44. Both the first damping hinge 41 and the second damping hinge 44 are damped. The first baffle 42 and the second baffle 43 can rotate between 0° and 180° along the central axis of the hinge position with the first damping hinge 41 and the second damping hinge 44 and remain stationary. The baffle assembly 4 can be completely housed in the cavity 2.

[0045] The electronic control component 6 includes a button assembly 61 and a control device 63 (not shown in the figure). For example... Figures 1 to 4 As shown, the button assembly 61 is disposed on the step surface of the step device 1, and the control device 63 is disposed in the cavity 2. The button assembly 61 includes three function buttons: "start", "lift" and "end". The button assembly 61 is connected to the control device 63 through wires. The control device 63 is connected to the push rod 34, the first damping hinge 41, the second damping hinge 44, the first rotating shaft 32 and the second rotating shaft 35 through wires and outputs action execution commands. The first damping hinge 41, the second damping hinge 44, the first rotating shaft 32 and the second rotating shaft 35 are all equipped with electric drive modules, which can perform corresponding actions when they receive the execution commands from the control device 63.

[0046] Specifically, when the step device 1 is in the normal step passage mode, such as Figure 1As shown, the first baffle 42 and the second baffle 43 are flipped and folded above the third baffle 45, and the lifting assembly 3 is completely housed in the cavity 2. Pedestrians can pass normally along the step device. The appearance of the step device 1 blends with the building environment and has no protruding parts.

[0047] Example 2

[0048] Furthermore, in this embodiment, to facilitate pedestrian passage, a barrier-free passage mode is provided where the lifting assembly 3 is raised as a whole to form a horizontal plane, as an improvement on embodiment 1. Figures 2 to 4 As shown, when the step device 1 needs to be switched to barrier-free access mode, the user presses the "Start" button on the button assembly 61. The rotating shaft 361 drives the rotating wheel 362 to rotate. The rotating wheel 362 drives the push rod 34 to extend outward horizontally from the telescopic opening 12 through gear meshing. When the push rod 34 is fully extended, the first rotating shaft 32 drives the push rod 34 to rotate to the ground. At the same time, the second rotating shaft 35 drives the third baffle 45 to rotate to the horizontal and to be in contact with the ground. Then, the first baffle 42 is rotated 180° to the horizontal and to be in contact with the ground by the first damping hinge 41. The second baffle 43 is rotated to the horizontal and to be in contact with the ground by the second damping hinge 41. Driven by the hinge 44, the hinge flips and overlaps the step. At this time, the user presses the "lift" button on the button assembly 61. The first pivot 32 drives the push rod 34 to rotate and rise to the height of the highest step. At this time, the horizontal plane formed by the first baffle 42 and the third baffle 45 is level with the height of the highest step. Driven by the second damping hinge 44, the second baffle 43 adjusts its angle until it forms the same horizontal plane as the first baffle 42 and the third baffle 45 and overlaps the highest step. At this time, the first baffle 42, the third baffle 45 and the second baffle 43 form a horizontal passage that can be passed through without obstacles.

[0049] The advantage of this embodiment is that it provides a convenient technical solution for switching between normal and barrier-free access modes on stairs. It addresses the problem of limited building space preventing the installation of compliant barrier-free ramps. It can replace traditional indoor and outdoor stairs with different elevations (or replace some of the stairs with this device). Through the lifting components and the retractable and fully retractable structural design, it achieves functional compatibility between normal and barrier-free access for pedestrians in scenarios with different elevations. It does not require additional modifications to the original building foundation, has a simple appearance, and can be integrated with the original style of the building.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
