Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator technology, specifically a cage-type manual elevator. Background Technology
[0002] Currently, home elevators are mainly divided into elevators and staircases. Elevators are primarily used in multi-story buildings, while staircases are mainly used in two-story duplexes. In duplexes, to prevent excessive inclination angles and for the safety of users, a spiral design is often used to reduce the inclination angle. However, this also leads to the problem of the staircase taking up too much space. Elevators are not suitable for duplexes with fewer floors. In addition, the elderly and other frail people are prone to falling down the stairs. Therefore, we have designed a cage-type human ladder. The cage-type ladder frame is designed with multiple sliding support plates. By controlling the distance of pulling out the support plates, the support plates act as the seat and standing platform for the user inside the cage-type ladder. Users can safely complete the upstairs movement inside the cage by repeatedly standing and sitting. It has a small footprint and can effectively ensure the safety of the elderly and frail when going up and down stairs. Moreover, compared with elevators, it is more suitable for low-rise duplexes, with a simple structure, convenient operation, and low processing and installation costs. Summary of the Invention
[0003] The purpose of this invention is to provide a cage-type human ladder to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A cage-type manual ladder includes a ladder support frame. The front side of the ladder support frame has symmetrical lower ladder doors and an upper ladder door located above the lower ladder doors. The inner sides of the lower ladder doors and the upper ladder doors, as well as the inner wall of the rear side of the ladder support frame, are provided with corresponding sets of guide rods. A slidable support plate is provided between each set of guide rods. By adjusting the position of the support plate on the guide rods, the user can sit or stand on the support plate.
[0006] Using the above technical solution, after entering the cage-type elevator, users can close the lower door and pull out the support plate to sit or stand up. They can go up and down the floors by using their own standing and sitting postures. When the elderly or weak are tired, they can sit directly on the support plate to rest and recover their strength. It is highly safe and practical.
[0007] As a further embodiment of the present invention: a groove is provided on the inner side of the guide rod, and the two sides of the support plate are slidably disposed in the groove.
[0008] As a further embodiment of the present invention: the uppermost slide is half the length of the lower slide, and the uppermost support plate is half the length of the lower support plate.
[0009] By adopting the above technical solution, the uppermost support plate is designed to be half the length of the lower support plate, so that the uppermost support plate only serves as a place for users to sit, making it convenient for users to move the support plate when entering or leaving the elevator from above.
[0010] As a further embodiment of the present invention: two symmetrical L-shaped loop hooks are provided at the front of the uppermost support plate, and a cap corresponding to the L-shaped loop hook is provided on the upper side of the two guide rods that are close to each other, and the L-shaped loop hook can be locked in the cap.
[0011] By adopting the above technical solution and designing an L-shaped hook, when the uppermost support plate is behind the upper ladder door on one side, the upper ladder door on the other side cannot be opened. This avoids the problem of users stepping into empty spaces when they are not clear about the exact location of the uppermost support plate, thus ensuring the safety of users.
[0012] As a further embodiment of the present invention: both the lower ladder door and the upper ladder door are provided with door locks for engaging with the box ladder support.
[0013] By adopting the above technical solution and designing a door lock, the elevator can be closed and the door can be fixed after the user enters the elevator. This ensures that the support plate can slide stably within the guide rod and also guarantees the safety of the user when moving inside the elevator.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The human-powered ladder designed by this invention allows users to sit or stand up by pulling out a support plate, using their own sitting or standing posture to go up and down floors. It is especially safe for the elderly and those with weak constitutions to use, and it is also green, environmentally friendly, and takes up little space, solving the problems of inconvenience in using elevators in duplex apartments and the problems of excessive space and safety of staircases.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Example 1
[0026] Please see Figure 1-7 This embodiment provides a cage-type manual ladder, including a ladder support frame. The front side of the ladder support frame has symmetrical lower ladder doors 8 and an upper ladder door 10 located above the lower ladder doors 8. Both the lower ladder doors 8 and the upper ladder door 10 are equipped with door locks 9 for engaging with the ladder support frame. Figure 5 and Figure 6 To facilitate the installation of the ladder doors, as is a conventional operation familiar to those skilled in the art, the ladder support frame consists of a left support rod 1, a middle support rod 2, and a right support rod 3, with corresponding left and right support rods, and a door beam rod 13 for engaging with the edge of the ladder doors. Specifically, the ladder doors on both sides are hinged to the left support rod 1 and the right support rod 3, respectively. The door locks 9 on the ladder doors are obtained directly, such as a bullhead lock. The middle support rod 2 is equipped with a lock box corresponding to the door lock 9, enabling engagement with the door lock 9. Figure 2-5 as well as Figure 7 As shown, both the lower ladder door 8 and the upper ladder door 10 use slatted door panels. Multiple sets of guide rods 4 are provided on the inner sides of the lower ladder door 8 and the upper ladder door 10, as well as on the rear inner wall of the elevator box support. A slidable support plate 6 is provided between each set of guide rods 4. Specifically, a groove 5 is provided on the inner side of the guide rod 4, and the support plate 6 is slidably disposed within the groove 5 on both sides. By adjusting the position of the support plate 6 on the guide rod 4, the user can sit or stand on the support plate 6. It should be noted that... (The text abruptly ends here, likely due to an incomplete sentence or missing information.) Figure 2The rear guide rod 4 is a one-piece guide rod, fixed to the inside of the left support rod 1, the middle support rod 2, and the right support rod 3. It can be fixed by welding. The front guide rod 4 is divided into two sections, which are fixed to the ladder doors on both sides respectively. When the ladder doors are closed, the two guide rods 4 at the same height on the same side are aligned, allowing the support plate 6 to slide between the broken guide rods 4. Figure 1-4 As shown, in order to make the uppermost support plate 6 only serve the purpose of allowing the user to sit down, and the uppermost support plate 6 is half the length of the lower support plate 6, the corresponding slide groove 5 is also half the length of the lower slide groove 5.
[0027] Furthermore, combined with Figure 3 and Figure 4 As shown, to ensure that the side of the upper ladder door that the user opens when entering the elevator box is the side where the support plate 6 is located, two symmetrical L-shaped loop hooks 11 are provided at the front of the uppermost support plate 6. Caps corresponding to the L-shaped loop hooks 11 are provided on the upper side of the two uppermost guide rods 4 that are close to each other. The L-shaped loop hooks 11 can be locked into the caps 12. Figure 3 When the uppermost support plate 6 is located behind the left upper ladder door 10, the L-shaped hook 11 on the right side is locked with the cap on the guide rod 4 behind the right upper ladder door 10. At this time, the left upper ladder door can only be opened from the outside. Similarly, when the uppermost support plate 6 is located on the right side, only the corresponding right upper ladder door 10 can be opened, thus avoiding the problem of users stepping into the air.
[0028] In addition, considering the practicality and safety of the elevator box, grid baffles are installed on both the left and right sides of the elevator box during actual installation. This is to prevent users from falling from the side and to make it easier for users to extend their feet out of the grid and push the support plate under their feet back when climbing the ladder. At the same time, a baffle is welded to the rear of the elevator box to facilitate fixing the rear of the box to the indoor wall.
[0029] The specific operating method is as follows: Taking a box ladder support with a length of 1.4 meters, a width of 0.7 meters, and a height of 2.4 meters as an example, there are eight layers of support plates 6 with a height difference of 30 centimeters. The top support plate 6 is a rectangle with a length of 69 centimeters, a width of 20 centimeters, and a thickness of 3 centimeters. The remaining support plates 6 below are squares with a length of 69 centimeters, a width of 69 centimeters, and a thickness of 3 centimeters.
[0030] (a) When one or more people are going upstairs, each person opens the lower ladder door 8 on the side without support plate 6, enters, and stands on the lowest support plate 6, which is 30 cm above the ground. At this time, the user has already risen 30 cm. Inside the elevator box, the user pulls out the second support plate 6, which is 60 cm above the ground, and the third support plate 6, which is 90 cm above the ground. Both the second and third support plates 6 are pulled out 20 cm. Then, the user turns around and closes the lower ladder door 8, and sits on the support plate 6, which is 90 cm above the ground. Then, the user lifts both feet and places them on the support plate 6, which is 60 cm above the ground, and pulls the support plate 6, which is 60 cm above the ground, along the guide rod 4 to slide into place on the side facing the user. Then, the user stands up. Starting on the support plate 60 cm above the ground, the person going upstairs has risen 60 cm. At the same time, the hands behind them pull out the support plate 6 120 cm above the ground, pull it out 20 cm, and sit on the support plate 6. Then, lift both feet off the support plate 6 6 60 cm above the ground and place them on the support plate 6 90 cm above the ground. Use the feet to pull the support plate 6 in front of the body to move it. After reaching the position, stand on the support plate 6 90 cm above the ground. At this time, the person has risen 90 cm. Repeat the above standing and sitting actions to safely complete the upstairs action in the cage. After reaching the top support plate 6, open the corresponding ladder door 10 to reach the second floor.
[0031] (ii) When one or more people are going downstairs, each person enters the elevator box through the upper door 10 and chooses the side with the support plate 6. They stand on the seventh support plate 6, which is 210 cm high. At this time, the person going downstairs sits on the uppermost support plate 6 and uses their feet to control the seventh support plate 6 to move backward 50 cm. Then, they lower their feet from the seventh support plate 6 to the sixth support plate 6. At this time, the person's buttocks leave the uppermost support plate 6 and sit on the seventh support plate 6, completing a 30 cm descent. Then, they use their feet to control the sixth support plate 6 to move backward 50 cm and lower their feet from the sixth support plate 6 to the fifth support plate 6, sitting on the sixth support plate 6. This completes another 30 cm downward movement. By repeating this action, the person can safely complete the descent inside the elevator box.
[0032] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application.
