A multi-position controllable car elevator

Abstract

This invention relates to a multi-position controllable car elevator. The device uses a ring-shaped frame installed on the top of the car 1 to display the floor, and a U-shaped drive component formed by ropes along the car's waistline controls the switch on the top of the car. The ring-shaped frame, positioned on the top of the car 1, allows passengers inside the car to easily see whether their desired floor has been selected simply by looking up. If not selected, passengers can directly choose their desired floor using the rope 2 along the car's waistline. The rope at the waistline occupies little space, is easy to operate, and because it is inelastic and comfortable to hold, it can also be used as a handle, allowing floor selection to be achieved from any position within the car.

Description

Technical Field

[0001] This invention relates to the field of elevators, and in particular to a multi-position controllable car elevator. Background Technology

[0002] The car elevator is one of the most common types of elevators in our lives. Due to its fast operating speed, high safety, and small footprint, the car elevator is widely used in various buildings.

[0003] Traditional elevator floor buttons are typically located vertically on the right-hand side of the car door. For larger elevators or in specific environments such as hospitals and shopping malls, auxiliary buttons are often installed on one side wall to accommodate children and wheelchair users. However, with evolving market demands, single-position elevator buttons and elevators with only auxiliary buttons are increasingly unable to meet people's needs. This is especially true for elevators in office buildings, which are generally larger and experience higher passenger volumes and more complex floor requirements, particularly during peak hours. Single-position buttons are no longer sufficient, often leading to pushing and shoving, and inevitably physical contact. This further diminishes the passenger experience for sensitive or introverted individuals. Currently… The solutions to the above problems often involve increasing the number of elevator buttons. However, each elevator button is used in pairs, and a set of buttons occupies a specific space. The number of individual passengers that space can serve is limited, and the buttons are easily blocked, resulting in mediocre effectiveness. Therefore, this approach has not been widely adopted. Existing technology provides a solution, for example, patent application number 202123409218.7, entitled "An Elevator Car Button Switch." This solution allows for the control of a switch by placing airbags in different locations. Multiple airbags in different locations can control the opening and closing of a single switch, thus enabling control of elevator buttons from different positions. However, this method is essentially the same as installing multiple sets of elevator buttons, only replacing multiple sets of switches with multiple sets of airbags. It still occupies a large amount of space inside the elevator, and finding the airbags is inconvenient. Furthermore, it is difficult to effectively confirm whether the desired floor has been pressed.

[0004] Currently, the foreseeable solutions to this problem include: 1. Intelligent voice control, but this method has obvious drawbacks due to the noisy environment inside the elevator. 2. Connecting to a smartphone via Bluetooth or the internet, but this is cumbersome to operate, and Bluetooth multi-device connections are prone to accidental touches. Furthermore, elevators typically have multiple devices, making accidental connections a common problem. These are just some of the inconveniences associated with intelligent control methods. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a multi-position controllable car type 1 elevator, which effectively solves the problems raised in the prior art.

[0006] The technical solution to this problem includes a car with a vertical shaft rotatably mounted in the center of the top of the car. A ring-shaped frame is coaxially fixed to the lower end of the shaft. Multiple indicator lights with floor numbers are evenly distributed around the lower surface of the ring-shaped frame. Multiple ratchet teeth, each corresponding to an indicator light and facing the same direction, are evenly distributed around the outer surface of the ring-shaped frame. The root of each ratchet tooth interlocks with the head of an adjacent ratchet tooth on one side, forming an inclined groove between adjacent ratchet teeth. A switch corresponding to the indicator light is installed at the bottom of the groove. The switch is connected in parallel with the car's existing floor buttons. Both the switch and the buttons allow for floor selection. The indicator lights on the switches and the buttons... The indicator lights open and close synchronously. A telescopic rod with its extended end facing the center of the ring frame is installed on the top of the car. A spring is fitted on the telescopic rod to drive its extended end to return to the ring frame. An L-shaped rod is fixed to the extended end of the telescopic rod. The vertical end of the L-shaped rod is always in contact with the ratchet and can contact the switch through the through slot. A rope pulley is coaxially fixed on the vertical shaft and placed above the ring frame. Multiple fixed pulleys are provided on the waistline of the car and near the top of the car. A closed-loop rope is positioned and supported on the rope pulley and the fixed pulley. After positioning, the rope forms a U-shape with an opening facing the car door on the waistline of the car. Pulling the rope can drive the rope pulley to rotate.

[0007] Preferably, the switch and floor buttons are connected in parallel with the elevator floor controller, that is, the switch and floor buttons can each give an open / close signal to the floor controller independently, and the indicator lights on the switch and the floor buttons open and close synchronously with the floor controller.

[0008] Preferably, the switch is a touch switch with a protective pad installed on it. The switch can be turned on by pressing the protective pad with the L-shaped rod, and the controller can turn off the switch while the L-shaped rod is pressing the protective pad.

[0009] Preferably, a ring-shaped baffle is provided below the ratchet, which is coaxial with the ring frame. The inner diameter of the baffle is consistent with the outer diameter of the ring frame, and the baffle is provided with a prompt indicating the driving mode.

[0010] Preferably, the rope is provided with two symmetrical tensioning pulleys on the side near the door, and the rope is fitted onto the rope pulleys through the inner sides of the two tensioning pulleys.

[0011] Preferably, protective covers are installed on the outside of the fixed pulleys located on the waistline of the car, and the ropes pass through the protective covers.

[0012] Preferably, the fixed pulleys should include at least six, four of which are respectively placed at the bending positions of the car waistline rope, and the other two are respectively placed at the rope bending positions near the top of the car.

[0013] Preferably, a pointer is installed on the telescopic rod, positioned below the baffle, with the pointer pointing towards the ring frame.

[0014] Preferably, a roller is fitted on the vertical end of the L-shaped rod, the roller is in contact with the ratchet, and the roller can be placed in the through groove and in contact with the switch.

[0015] This device uses a ring-shaped frame installed on the top of the car to display the floor number, and a U-shaped drive rope formed by a rope at the waistline of the car controls the switch on the top of the car. People in the car only need to look up to see whether the floor they want to go to has been selected. The sensory experience is clear, and the desired floor can be selected directly by the rope at the waistline of the car. The rope at the waistline takes up little space and is easy to operate.

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5As can be seen, the present invention includes a car 1. A vertical shaft 2 is rotatably installed at the top center of the car 1. A ring frame 3 is coaxially fixed at the lower end of the shaft. Multiple indicator lights 4 with floor numbers are evenly distributed around the lower end surface of the ring frame 3. Multiple ratchet teeth 5, each corresponding to an indicator light 4 and facing the same direction, are evenly distributed around the outer circumference of the ring frame 3. The root of the ratchet tooth 5 and the head of the adjacent ratchet tooth 5 on one side overlap each other, forming an inclined through groove between the adjacent ratchet teeth 5. A switch 6 corresponding to an indicator light 4 is installed at the bottom of the through groove. The switch 6 is connected in parallel with the floor buttons of the car 1. Both the switch 6 and the buttons can select the floor. The indicator lights 4 on the switch 6 and the indicator lights 4 on the buttons open and close synchronously. A telescopic rod 7 with its extended end facing the center of the ring frame 3 is installed on the top of the car 1. A spring 8 is fitted on the telescopic rod 7 to drive its extended end to return to the ring frame 3. An L-shaped rod 9 is fixed to the extended end of the telescopic rod 7. The vertical end of the L-shaped rod 9 is always in contact with the ratchet 5 and can contact the switch 6 through the through groove. A rope wheel 10 placed above the ring frame 3 is coaxially fixed on the vertical shaft 2. Multiple fixed pulleys 11 are provided on the waistline of the car 1 and near the top of the car 1. A closed-loop rope 12 is positioned and supported on the rope wheel 10 and the fixed pulleys 11. After positioning, the rope 12 forms a U-shape with an opening facing the car door on the waistline of the car 1. Pulling the rope 12 can drive the rope wheel 10 to rotate.

[0023] In order to achieve synchronous control of switch 6 and floor buttons, switch 6 and floor buttons are connected in parallel with the elevator floor controller, that is, switch 6 and floor buttons can each give an opening and closing signal to the floor controller independently, and the indicator light 4 on switch 6 and the indicator light 4 on floor buttons are opened and closed synchronously with the floor controller.

[0024] To facilitate the opening and closing of switch 6, switch 6 is a touch switch 6 with a protective pad installed on it. The L-shaped rod 9 can open switch 6 by squeezing the protective pad, and the controller can close switch 6 while the L-shaped rod 9 keeps squeezing the protective pad.

[0025] To achieve the desired overall appearance of the device, a ring-shaped baffle 13 coaxial with the ring frame 3 is provided below the ratchet 5. The inner diameter of the baffle 13 is consistent with the outer diameter of the ring frame 3, and the baffle 13 is provided with a prompt indicating the driving mode.

[0026] For the purpose of wrapping and supporting the rope 12, two symmetrical tensioning pulleys 14 are provided on the side of the rope 12 near the door, and the rope 12 is fitted onto the rope pulley 10 through the inner side of the two tensioning pulleys 14.

[0027] To prevent people from getting their hands caught in the fixed pulleys 11 when driving the rope 12, protective covers are installed on the outside of the fixed pulleys 11 located on the waistline of the car 1, and the rope 12 passes through the protective covers.

[0028] In order to guide the rope 12, the fixed pulley 11 should include at least six, four of which are respectively placed at the bending position of the waistline rope 12 of the car 1, and the other two are respectively placed at the bending position of the rope 12 near the top of the car 1.

[0029] To achieve a better display and indication effect, a pointer 15 is installed on the telescopic rod 7, which is located below the baffle 13 and faces the ring frame 3.

[0030] To reduce friction between the L-shaped rod 9 and the ratchet 5, a roller 16 is fitted on the vertical end of the L-shaped rod 9. The roller 16 contacts the ratchet 5 and can be placed in the through groove and contact the switch 6.

[0031] The specific working process of this invention: When this device is in use, only the ring frame 3, the baffle 13 on the outside of the ring frame 3, the pointer 15, and the ropes 12 on the waistline of the car 1, the corners of the car 1, and the top of the car 1 can be seen inside the car 1. The ropes 12 are non-elastic and easy to hold. There is a gap between the ropes 12 and the wall of the car 1 at the waistline position, which is convenient for hand gripping. An advertising space is set in the middle of the ring frame 3, which is convenient for adding advertisements later.

[0032] When a passenger is inside the car 1 and their position is far from or inconvenient to reach the buttons provided in the car 1, the passenger can randomly move closer to the wall of the car 1 or directly reach out to drive the rope 12. The rotation of the rope 12 is directly driven by the fixed pulley 11 and the tension wheel 14. The rotation of the rope wheel 10 drives the ring frame 3 to rotate. The driving method of the rope 12 is indicated on the baffle 13: "Drive the turntable counterclockwise until the pointer 15 points to the selected floor number, then release the rope 12." The turntable mentioned in the text is the combination of the support frame and the baffle 13. The user is required to drive the rope 12 counterclockwise, which drives the ring frame 3 to rotate counterclockwise. In the initial state, under the reset action of the spring 8, the roller 16 fitted on the end of the L-shaped rod 9 is placed at the bottom of the through groove and in contact with the protective pad. When the ring frame 3 is driven, the inclined ratchet 5 will drive the telescopic rod 7 to retract, and at the same time the spring 8 is compressed. When the ring frame 3 is continuously driven, the L-shaped rod 9 moves from one ratchet 5 to the other. When moving on a ratchet 5, it will not approach the bottom of the slot because the person holding the rope 12 will not let go. During this process, the driving rope 12 drives the ring frame 3 to select the floor number. After the floor number is selected, the pointer 15 points to the corresponding indicator light 4. At this time, the rope 12 is released, and the L-shaped rod 9 returns to the ring frame 3 under the reset action of the spring 8. During this process, the roller 16 will move along the inclined outer surface of the pawl at this position in the direction of the axis of the ring frame 3. This process will drive the ring frame 3 to reverse until the L-shaped rod 9 contacts the protective pad layer, thereby opening the switch 6 at this position and realizing the floor selection. At this time, the button light of the floor is lit, and the floor is confirmed. The switch 6 driven by the pull rope only has an on function and no off function. Pulling the rope will open the switch 6. It will automatically close after reaching the designated floor or when reaching the ground floor or the bottom floor. If the wrong floor is selected, there is no need to cancel or it can be canceled directly through the buttons on the car 1.

[0033] This device has the following advantages compared to traditional equipment:

[0034] 1. This device uses a ring frame 3 installed on the top of the car 1 to display the floor, and uses a rope 12 at the waistline of the car 1 to form a U-shaped drive component to control the switch 6 on the top of the car 1. The ring frame 3 is placed on the top of the car 1, so people in the car 1 only need to look up to see whether the floor they want to go to has been selected. The sensory experience is clear. If it has not been selected, the desired floor can be selected directly by using the rope 12 at the waistline of the car 1. The rope 12 at the waistline occupies little space and is easy to operate. Because it is inelastic and comfortable to hold, it can also be used as a handle, so that the floor can be selected from any position in the car 1.

[0035] 2. The floor selection operation is convenient. There are clear and easy-to-understand prompts on the stop plate 13, and it is also very easy to operate. As the prompts indicate, "Drive the turntable counterclockwise so that the pointer 15 points to the selected floor number, and then release the rope 12." The operation is simple and convenient. Compared with complex equipment and intelligent equipment, this car 1 has low manufacturing cost and is easy to promote.

[0036] 3. In this device, the L-shaped lever 9 is always in contact with the ratchet 5. Therefore, when the L-shaped lever 9 moves from one ratchet 5 to another, there is a noticeable jamming sensation. Combined with the indication of the pointer 15, the corresponding floor can be found clearly and accurately. This will not cause incorrect selection due to the deviation of the pointer 15, making the device more accurate and efficient in use.
