DESC:FIELD OF INVENTION
[0001] Embodiments of the present disclosure relate to the field of passenger conveyance and transportation equipment and more particularly a portable lift machine for elevating passengers to upper berth in trains and a method.
BACKGROUND
[0002] Typically, the train compartments features a range of seating arrangements, including lower, middle, and upper berths in a sleeper and AC classes. The lower berth offers most accessible sleeping arrangement, located at ground level for easy entry and exit while the middle and the upper berth requires climbing and may be less accessible.

[0003] The upper berth in trains, particularly in the sleeper and AC compartments, has been a feature of rail travel for many years. It is a common choice for passengers seeking an affordable yet relatively private space. These upper berths are designed to accommodate passengers who are willing to climb up to a higher level within the compartment. However, this arrangement presents a significant challenge, especially for elderly passengers, people with disabilities, or those with health issues, as the climb can be physically demanding. The entry to the upper berth is typically through a narrow, steep ladder, and once a passenger reaches the top, they often have limited space and accessibility.

[0004] Currently, when passengers are unable to reach the upper berth on their own, they are forced to request assistance from co-passengers or the train ticket examiner (TTE). The TTE, while willing to assist, is often unable to offer much help due to time constraints, while fellow passengers may be unwilling or unable to aid due to their own travel arrangements. The situation becomes particularly problematic when passengers who have been waiting for months to secure a specific berth are asked to switch with someone else. This creates discomfort and potential conflict among passengers, as the rearranging of travel plans is rarely well-received.

[0005] Additionally, the existing method of assistance is limited and does not address the underlying issue of accessibility to the upper berth, especially for those who may not be physically capable of climbing the ladder. In most cases, the passenger who needs help must rely on others, which adds unnecessary inconvenience and can lead to frustration on both sides. Furthermore, the lack of any automated or efficient means to ascend to the upper berth exacerbates the problem, particularly when trains are crowded, and space is at a premium. This lack of accessibility has prompted calls for improvements in train design and passenger services to ensure more equitable access to all parts of the train.

[0006] In response to these challenges, there exists a need to address these challenges and provide a constructive solution for passengers who struggle to reach to the upper berths. The proposed solution is adapted to eliminate the need for passengers to rely on fellow travellers and train ticket examiners, making the travel experience smoother, more comfortable, and fair for everyone. Additionally, the proposed solution aims to bridge the gap between the current accessibility limitations and the need for an inclusive travel experience, enhancing the overall quality of rail travel.

[0007] Hence there is a need for an improved a portable lift machine for elevating passengers to upper berth in trains and a method which addresses the aforementioned issue(s).

OBJECTIVES OF THE INVENTION
[0008] The primary objective of the invention is to provide a portable lift machine that aids in lifting passengers onto the upper berth of a train. This machine enhances accessibility and convenience for individuals with mobility challenges.

[0009] Another objective of the invention is to introduce a machine adapted to feature a rectangular base frame mounted on plurality of wheels, with optimum length and width making it a compatible choice and offer stability and mobility. It also ensures ease of movement within confined space including train compartments.

[0010] Yet another objective of the invention is to accommodate the portable lift machine equipped with a scissor lift structure adapted to support a rectangular platform. The rectangular platform can reach a maximum height of 1500 mm and a minimum of 300 mm, making it adaptable for various user needs. This innovative design offers a practical solution to overcome the height disparity of train berths.
