Description

Technical Field

[0001] This utility model relates to a building facility, namely a planar passageway safety elevator. Background Technology

[0002] Elevators are essential facilities in high-rise buildings, especially vertical elevators. These elevators all have doors. The doors include the car door installed on the elevator car and the landing door installed at each floor entrance. The upper edges of both the car and landing doors slide along tracks and can move left and right under the drive of a motor. The lower edges of both doors slide along tracks on the floor via pulleys. These tracks can be grooves or raised ridges, their main function being to limit the elevator door's offset, allowing it to slide in a straight line. While the tracks on the floor play a crucial role, they also have several drawbacks. For example, an uneven floor can hinder movement, especially for the elderly or children with mobility issues. Women wearing high heels are particularly vulnerable, as their heels can easily get stuck in the grooves, causing danger and embarrassment. Secondly, the grooves easily accumulate dirt, making cleaning difficult, increasing resistance, and are unsightly. Furthermore, the uneven floor structure requires a thicker threshold. Since the weight of the elevator door is mainly borne by the upper track, the pressure on the lower track is not high, and the strength requirement is not significant. Therefore, thickening the door sill not only wastes materials but also deepens the gaps between the car door and the landing door on both sides of the bottom plate, increasing safety hazards and making it more difficult to seal the gaps. Summary of the Invention

[0003] The purpose of this utility model is to provide a planar passage safety elevator with a bottom plate under the elevator door that is free of bumps and depressions, facilitates passage, is clean and aesthetically pleasing, and has a shallow gap between the car door and the landing door bottom plate that is easy to seal.

[0004] The above objective is achieved by the following technical solution: a planar passage safety elevator, including an elevator door, the upper part of which slides in conjunction with a slide rail and can move left and right under the drive of a motor, characterized in that: the bottom plate of the passage after the elevator door is opened is a planar component without grooves or protrusions, and a support rail is provided outside the passage to constrain the elevator door to slide in a straight line.

[0005] The support rail is installed on the inside of the elevator door, and the elevator door slides in conjunction with the support rail.

[0006] The elevator door is a car door installed on the outside of the car. The support rail is long and flat, installed on the outer wall of the car, and opposite to the lower inner side of the car door. The inner side of the car door is equipped with a slider that slides with the support rail.

[0007] The elevator door is a landing door installed on the elevator entrance of the floor wall. The support rail is long and flat, installed on the inner side of the floor wall, and opposite to the lower inner side of the landing door. The inner side of the landing door is equipped with a slider that slides with the support rail.

[0008] The elevator door is equipped with pulleys on its lower edge, and the pulleys press against the bottom plate.

[0009] The elevator door is equipped with multiple pulleys on its underside. The pulleys press against the bottom plate, which has grooved or convex rails. The pulleys slide in conjunction with the rails, and the inner end of the rails is outside the elevator shaft. When the elevator door is closed, there are at least two pulleys engaged with the rails.

[0010] The bottom plate under the elevator door is equipped with a flexible board at the front end. When the elevator car door and the landing door are facing each other, the flexible board seals the gap between the bottom plate under the car door and the bottom plate under the landing door.

[0011] The front edge hinge of the car floor has a long, rigid flap. A control mechanism for the flap is located under the floor. When the car door is closed, the flap is suspended below the front of the floor with the flap facing forward. When the car door is opened, the control mechanism drives the flap to flip upward, and the flap faces upward to seal the gap between the car floor and the landing door floor. During the closing process of the car door, the flap swings downward to return to the suspended state.

[0012] The control mechanism consists of a cam mounted on a camshaft under the car floor. The cam's wheel surface is parallel to the floor, and its contact abuts against the rear side of the flap. The cam has a horizontal elongated hole, inside which a rocker arm is installed. A through groove is cut into the car floor, and a vertical sliding shaft is installed under the lower outer corner of the car door. The sliding shaft passes through the through groove, and its lower end is hinged to the front end of the rocker arm. When the car door is opened, the sliding shaft drives the rocker arm to rotate the cam, causing the cam's contact to move forward. This pushes the flap upward to seal the gap between the car floor and the landing door floor. When the car door is closed, the sliding shaft returns to its original position, causing the cam and flap to return to their original positions.

[0013] The control mechanism consists of a turntable mounted on the underside of the car floor via a turntable shaft. The turntable has a through hole, within which a rocker arm is installed. The turntable surface is hinged to the rear end of a push rod via a crank shaft. The front end of the push rod abuts against the surface of the flap. A through groove is cut into the car floor. A vertical sliding shaft is installed below the lower outer corner of the car door, passing through the through groove. The lower end of the sliding shaft is hinged to the front end of the rocker arm. When the car door opens, the sliding shaft drives the rocker arm to rotate the turntable, causing the push rod to move forward, which in turn pushes the flap upward to seal the gap between the car floor and the landing door floor. When the car door closes, the sliding shaft returns to its original position, causing the turntable and flap to return to their original positions.

[0014] The beneficial effects of this utility model are: the support rail for preventing elevator door misalignment is not on the elevator shaft, eliminating the need for uneven tracks on the shaft floor, thus removing obstacles to passage, making entry and exit more convenient and safer, and preventing the accumulation of dirt, resulting in a cleaner and more aesthetically pleasing appearance. Because there is no uneven structure, the base plate is very thin, and the gap between the base plates on both sides of the car door and landing door is very shallow, facilitating the installation of gap-sealing components. Furthermore, its simple structure, low cost, safety, and reliability make its application prospects very promising. Attached Figure Description

[0036] The overall concept of this utility model is to eliminate the raised and recessed tracks on the original elevator shaft floor and adopt a flat floor, thereby making passage more convenient and safer. Six embodiments are described below based on this concept.

[0037] First embodiment: Figure 1 illustrates a vertically moving elevator with a passenger-carrying car 1. The car moves up and down along the elevator shaft 8 under the pull of a traction mechanism. The car is composed of surrounding wall panels, a top cover, and a bottom plate 7. The car walls have openings for passenger access, and the openings are equipped with car doors 2.

[0038] Each floor along the elevator shaft is equipped with a landing door (5). When the elevator car stops at a floor, the car door and the landing door are aligned. Both the car door and the landing door open simultaneously, allowing passengers to enter and exit. Afterward, the car door and the landing door close, and the elevator continues its journey.

[0039] The car door 2 and landing door 5 here are collectively referred to as elevator doors. Both are rectangular flat panels, slidably connected to the slide rail 3 above the door, and can move left and right under the drive of a motor. The improvement is that the original grooved or ridged tracks on the bottom plate 7 below the elevator door have been removed, and a flat plate without grooves or ridges has been used. A support rail 6 is provided on the lower inner side of the elevator door, and the elevator door slides in conjunction with the support rail. The improvements to the elevator door include the following two forms:

[0040] The first type has a car door 2 installed on the outside of the car 1. Referring to Figures 2 and 3, a slide rail 3 is provided above the car, and the car door is suspended from the slide rail 3 and slides along it, allowing it to move left and right under the drive of a motor. The slide rail 3 and other components, being standard parts, are not shown in detail here. As seen in the figures, a support rail 6 is provided on the lower inner side of the car door, along which the car door 2 can slide.

[0041] There are various structures and installation methods for the guide rail; Figures 2 and 3 only illustrate one. Referring to Figure 4, the guide rail 6 is elongated and installed horizontally on the outer side of the car wall 10, opposite the lower inner side of the car door 2. The cross-section of the guide rail is a rectangular ring with an outer opening. Ideally, the guide rail 6 is embedded inside the car wall, with one opening flush with the entire car wall. The guide rail slides in conjunction with the slider 9, with one side of the slider extending out of the rectangular ring of the guide rail and connecting to the car door. In this way, the car door can move left and right under the constraint of the guide rail.

[0042] As shown in Figure 2, when the car doors are closed, the two doors slide towards each other and close under the drive of the motor. Partial support rails are visible on the car walls on both sides of the doors. As shown in Figure 3, when the car doors are opened, they separate to the sides under the drive of the motor. At this time, the floor plate 7 of the passageway is very flat and aesthetically pleasing, without any grooves or protrusions. This eliminates obstacles and facilitates passage.

[0043] Alternatively, the elevator door is a landing door installed on the inner side of the wall 4 at the floor opening. As shown in Figure 1 and referring to Figures 2, 3, and 4, the landing door slides along a track at the top, and the inner side of the landing door slides along a rail 6 via a slider 9. The rail 6 is elongated and installed horizontally on the inner side of the floor wall 4. Conversely, the elongated rail can be installed on the side of the landing door, and a slider that slides along the rail can be installed on the floor wall. Since the structural principle and working method of the landing door and rail are the same as those of the aforementioned car door, they will not be described again.

[0044] To further demonstrate that there are multiple structures and installations for the rail, Figures 5 and 6 illustrate two different structures.

[0045] As shown in Figure 5, the support rail is installed on the inside of the car door and is recessed into the outer wall of the car door, and the slider is connected to the car wall.

[0046] As shown in Figure 6, the support rail is installed between the car wall and the car door. The cross-section of the support rail is U-shaped, and the slider slides in the groove of the U-shape.

[0047] Clearly, the three structures shown in Figures 4, 5, and 6 above should all be considered equivalent technical solutions. Similarly, any component that is located outside the elevator shaft and slides in conjunction with the elevator door to constrain the elevator door from sliding in a straight line is a specific structural form of the support rail and is considered an equivalent technical solution.

[0048] At least one of the two types of elevator doors mentioned above should be improved, and ideally both should be improved simultaneously. After improvement, the elevator shaft floor will be flat, eliminating the original unevenness and making passage safer and more convenient. Because the uneven structure is eliminated, the floor plate does not need to be too thick, saving materials and significantly reducing the depth of the gap between the car door floor plate 7 and the landing door floor plate 7, as well as the difficulty of sealing the gap. The inner side of the elevator door uses a support rail to restrict the door's swing, replacing the function of the original uneven track and ensuring the elevator door's performance. The support rail is hidden inside the elevator door and cannot be seen from the outside, further enhancing the elevator's aesthetics and sophistication.

[0049] The second embodiment: As shown in Figure 7, a pulley 11 is installed under the lower edge of the car door 2 or landing door 5. The pulley rests on the top of the base plate 7, and the support rail 6 is installed on the inner side of the elevator door. In this way, part of the weight of the car door or landing door can still be shared by the base plate 7, while the direction of travel of the elevator door is determined by the upper slide rail 3 and the lower support rail 6. The pulley can be a miniature pulley, with its outer edge barely visible under the lower edge of the elevator door. Such a pulley can reduce the friction between the elevator door and the base plate without compromising the compactness and aesthetics of the structure.

[0050] The third embodiment: As shown in Figure 8, multiple pulleys 11 are mounted on the lower edge of the car door 2 or landing door 5, and the pulleys press against the bottom plate 7. A support rail 6 is located on the bottom plate, and the pulleys 11 and the support rail 6 are in sliding engagement. The structure of the support rail 6 can be varied. Referring to Figure 9, the support rail is a groove, and the outer edge of the engaging pulley is flat. Figure 10 As can be seen, the guide rail is a convex ridge, while the outer edge of the mating pulley is concave. Whether it's a groove or a convex ridge, the front end of the guide rail must not enter the elevator door passage. When the elevator door is open and the passage is fully open, the guide rail is not visible. When the elevator door is closed, most of the pulleys are pressed against the base plate, while the guide rail must have at least two pulleys. This type of guide rail both constrains the elevator door to slide in a straight line, preventing the lower part of the elevator door from shifting inwards or outwards, and does not disrupt the flatness of the passage. The surface of the passage base plate remains a flat surface without grooves or convex ridges, ensuring convenient and safe passage for personnel.

[0051] Fourth embodiment: As shown in Figures 11 and 12, a flexible soft board 12 is installed at the front end of the floor plate 7 of the car 1 or the floor plate 7 of the landing door 5. The soft board can be made of highly elastic materials such as rubber, latex, or polyurethane, and its width should be greater than or equal to the gap 13 between the car floor plate and the landing door floor plate. When the car door and the landing door are facing each other, the soft board can fill the gap 13 between the two floor plates. Since the gap between the car floor plate and the landing door floor plate is different, the width of the soft board should be equal to the larger gap. Taking the soft board installed in front of the landing door floor plate as an example, when the car is going up, as shown in Figure 11, the front edge of the soft board rests on the front edge of the car floor plate and is slightly bent upwards. When the car is going down, as shown in Figure 12, the front edge of the soft board rests on the front edge of the car floor plate and is slightly bent downwards. Clearly, this flexible panel neither hinders the car's movement up and down nor obstructs the gap between the car floor and the landing door floor. When passengers' belongings fall into the gap, they are intercepted by the flexible panel, preventing passenger loss. Because the gap between the two floor panels is small, generally about 20-40mm, and the flexible panel itself has a certain strength, its strength is further enhanced after being compressed through the gap, preventing items such as high heels from getting stuck.

[0052] Fifth embodiment: As mentioned above, since the elevator shaft has been modified by removing the grooves or protrusions and adopting a flat structure, the thickness of the bottom plate is greatly reduced, and the gap 13 between the car bottom plate and the landing door bottom plate is shallower and easier to seal.

[0053] Figures 13 and 14 illustrate a method for sealing gap 13. A long, rigid flap 14 is hinged to the front edge of the car floor via a pivot. The length of the flap should be greater than the width of the car passage, and the width of the flap should match the width of gap 13. Due to the large tolerance for gap width, the flap can use its maximum width or the width that appears most frequently. When the car door is closed, as shown in Figure 13, the flap hangs below the front of the floor with its surface facing forward, not obstructing the car's vertical movement. When the car door is open, as shown in Figure 14, the flap is pushed upward by a control mechanism, sealing gap 13 with its surface facing upward.

[0054] The control structure of the flap 14 includes various specific forms, with only one example shown in the figure: the control mechanism consists of a cam 18 mounted on the underside of the car floor 7 via a camshaft 19. The axis of the camshaft is perpendicular to the floor, the wheel surface of the cam is parallel to the floor, and the contact 15 of the cam abuts against the rear side of the flap. The cam has a horizontal elongated hole, within which a retractable rocker arm 20 is installed. A through groove 16 is formed on the car floor 7, and a vertical sliding shaft 17 is mounted below the lower outer corner of the car door 2. The sliding shaft passes through the through groove, and its lower end is hinged to the front end of the rocker arm 20.

[0055] As can be seen from Figures 13 and 15, when the car door is opened, the sliding shaft drives the swing rod to push the cam to rotate, and the contact of the cam moves forward, which pushes the flip plate 14 to flip upward and seal the gap 13 between the car floor and the landing door floor.

[0056] As can be seen from Figures 14 and 16, when the car door is closed, the sliding shaft returns to its original position, driving the cam and the flap back to their original positions.

[0057] Figures 15 and 16 are top-view diagrams illustrating the operational principle, where the base plate 7, represented by dashed lines, is the upper-level component. Clearly, this cam mechanism is very simple, with sensitive action and strong control, effectively solving the problem of sealing gaps in elevator base plates and possessing high practical value.

[0058] The sixth embodiment: As mentioned above, since the elevator shaft has been modified by removing the grooves or protrusions and adopting a flat structure, the thickness of the bottom plate is greatly reduced, and the gap 13 between the car bottom plate and the landing door bottom plate is shallower and easier to seal.

[0059] Figures 17 and 18 illustrate a sealing method for gap 13. A long, rigid flap 14 is hinged to the front edge of the car floor via a pivot. The length of the flap should be greater than the width of the car passage, and the width of the flap should match the width of gap 13. Due to the large width tolerance of the gap, the flap can use the maximum width or the width that appears most frequently. When the car door is closed, as shown in Figure 13, the flap hangs below the front of the floor with its surface facing forward, not obstructing the car's vertical movement. When the car door is opened, the flap is pushed upward by a control mechanism, sealing gap 13 with its surface facing upward.

[0060] The control structure of the flap 14 includes various specific forms, and only one is shown in the figure: The control mechanism is to install a turntable 21 under the bottom of the car floor via a turntable shaft 22. The turntable has a through hole, and a rocker arm 20 is installed in the through hole. The turntable 21 is hinged to the rear end of a push rod 24 via a crank shaft 23. The front end of the push rod 24 abuts against the surface of the flap 14. A through groove 16 is opened on the bottom plate 7 of the car 1. A vertical sliding shaft 17 is installed under the lower outer corner of the car door 2. The sliding shaft 17 passes through the through groove 16, and the lower end of the sliding shaft is hinged to the front end of the rocker arm 20.

[0061] As shown in the figure, the push rod can adopt a length-elastically adjustable structure, which can have a section of insert rod and a section of sleeve. The insert rod is inserted into the sleeve, and a spring is installed inside the sleeve. The front end of the push rod can be hinged to the flap via a pivot or a cross pivot.

[0062] As shown in Figures 17 and 19, when the elevator car reaches a certain floor and the car door opens, the sliding shaft under the lower corner of the car door moves outward, simultaneously pulling the swing arm 20 outward. As the swing arm extends, it drives the turntable 21 to rotate around the turntable shaft 22. The crank shaft 23 on the turntable drives the push rod to extend forward, pushing the flap upward to block the gap 13. When the width of the flap is equal to or less than the width of the gap, the upper surface of the flap can be flush with the bottom plates on both sides. If the width of the flap is slightly greater than the width of the gap 13, the outer edge of the flap stops below the bottom plate of the landing door. Because the bottom plate is very thin, even if the flap cannot completely enter the gap, the flatness of the three plates after sealing is very high. In particular, the aforementioned rods are all high-strength rigid rods, and the flap has sufficient rigidity after sealing to withstand being stepped on, ensuring safety and reliability.

[0063] As can be seen from Figures 18 and 20, when the car door is closed, the sliding shaft under the car door returns to its original position, which drives the swing arm, turntable and push rod to return to their original positions. The flap also returns to its original vertical hanging position and will not obstruct the operation of the car.

[0064] Figures 19 and 20 are schematic diagrams of the operation principle from a top-down perspective, where the base plate 7, etc., represented by dashed lines, are upper-level components.

[0065] As can be seen from the above, by eliminating the tracks on the elevator shaft floor, safety hazards in the shaft are eliminated, the cleanliness of the elevator is enhanced, the difficulty of sealing the gaps in the floor is reduced, and the overall performance of the elevator is greatly improved. It is expected to become a rapidly popular alternative product with a very promising market prospect.
