Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and specifically provides an orbital seat elevator that can climb along a staircase handrail. Background Art

[0002] At present, with the acceleration of urbanization, high-rise buildings are gradually increasing, and the application of elevators has also increased accordingly. However, in some old buildings, elevators are not installed, resulting in inconvenient travel for the elderly living on high floors or some people with mobility difficulties. Generally, the operation of the seat elevators on the market is relatively complex, and most of them cannot turn, and can only move between adjacent floors, requiring transfer, which is very inconvenient. There are also some intelligent seat elevators. Although they can turn, they are costly and suitable for use in independent multi-story houses and are not easily popularized. In view of the above problems, the purpose of the present invention is to provide a simple and low-cost walking elevator for the elderly and residents with inconvenient walking in old buildings without elevators, facilitating the residents to go up and down the stairs.

The middle track 3 is composed of a straight track and a small semi-circular track, so as to form a semi-circular sliding groove inside to realize the turning function. The inner side of the outer connecting plate 31 can be divided into four sliding grooves 33 by the inner spacer plates 32, making the sliding connection more convenient. The number of the conveying assemblies 4 is two. The conveying assembly 4 includes a chain 41 with an annular structure. The chains 41 on the two conveying assemblies 4 are located inside the four sliding grooves 33. One end of the middle track 3 is provided with a single-phase speed regulating motor 42 that drives the chain 41 to rotate. The model of the single-phase speed regulating motor 42 is 61K250RGN-CF, the working voltage is 220V, and the rotation speed is 30r / min.The resistance values of the starting winding and the running winding of this motor are constant.

The chain located on the chain rack is of model 10A-1, and the chain passing through the four semi-circular chutes is a side-bent chain, with its model being 10BSB, so as to meet the turning radius of 40 cm of this seat elevator. The single-phase speed-regulating motor 42 can drive the chain 41 to rotate, and the chain 41 can drive the folding seat assembly 7 to slide along the upper track 2 and the middle track 3. The telescopic sliding connection assembly 5 includes two sliding rods 52 with a U-shaped structure at the upper end. Two connecting springs 53 are provided between the two sliding rods 52, and upper sliders 51 are provided at the upper ends of the two sliding rods 52. A conical inclined groove is provided on the lower side of the upper slider 51. Iron chains 54 are provided on the sliding rods 52. An arc-shaped gravity-stabilizing sliding track 55 is provided between the lower ends of the two iron chains 54. The upper slider 51 can be slidably connected to the upper track 2, and the folding seat assembly 7 can be fixedly connected to the upper end through the iron chains 54 and the gravity-stabilizing sliding track 55.

The L-shaped folding seat 71 is made of thickened and reinforced cold-rolled steel material. When the slope of the stairs is less than 45 degrees, it can bear a person weighing 159 kg. When the slope of the stairs is greater than 45 degrees, it can bear a person weighing 136 kg. The gravity-stabilizing sliding track is arc-shaped, with a corresponding central angle of 108 degrees and a radius of the corresponding circle of 24 cm. People can sit on it through the L-shaped folding seat 71, making it more convenient to ride. The connection of the folding seat assembly 7 to the ground can be kept perpendicular at all times through the spring column, the slider 73 and the gravity-stabilizing sliding track 55, which provides convenience for people.,

[0025] In use: When the user presses the elevator button for the current floor, if the elevator is not in use, the elevator will move to the platform of the current floor. After the user sits down, press the controller on the elevator, and the elevator starts. During the movement of the elevator, due to the action of the gravity-stabilized sliding track, the user always maintains a state perpendicular to the ground. When the elevator turns, the two sliding rods automatically extend or compress as needed to ensure the smooth turning of the elevator. If a pedestrian enters the corridor during the movement of the elevator, the sensor installed in the corridor will receive the signal, thereby activating the voice warning device to give warnings to the passengers in the elevator and other pedestrians to avoid safety problems. In case of an emergency, the user can press the emergency deceleration device to make the elevator decelerate emergently, thus ensuring the safety of the user and pedestrians. When in motion, people can sit on the L-shaped folding seat 71. The folding seat assembly 7 is connected to the ground through the iron chain 54, the spring column, and the slider 73 and the gravity-stabilized sliding track 55, so that the folding seat assembly 7 always maintains a vertical state with the ground. The single-phase speed-regulating motor 42 can drive the chain 41 to rotate. Through the chain 41, the folding seat assembly 7 can slide along the upper track 2 and the middle track 3. The rotating wheel can be connected to the ground track 8 to make the sliding rod 52 slide more smoothly, thereby driving people up and down the stairs.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
