CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[0001] The present application claims no priority from any of the patent application(s).
TECHNICAL FIELD
[0002] The present disclosure relates to a field of apparatuses configured for ascending and descending. More specifically, the present specification relates to an uprearing and sinking assembly of a vehicle.
BACKGROUND
[0003] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present disclosure that are described or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements in this background section are to be read in this light, and not as admissions of prior art. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0004] Support devices are intricately engineered solutions intended to enhance the functionality, stability, and safety of vehicles. These devices play a crucial role in optimizing vehicle stability, providing support to the vehicle, and ensuring a safety of the vehicle and user. These sophisticated devices assume a pivotal role across multiple industries, encompassing automotive, aerospace, firearms, and industrial machineries.
[0005] Currently, a vehicle equipped with the support device faces a range of constraints. Notably, certain components of the vehicle are positioned at elevated heights on the vehicle, rendering them beyond reach for a vehicle operator. Moreover, during unforeseen events or while conducting specific tasks, the vehicle operator may require prompt access to these components.
[0006] To achieve this, the operator relies on an external mechanism, for example a ladder or any other arrangement, to access those elevated areas on the vehicle. This process entails the assembly and deployment of the external mechanism onto the vehicle for facilitating access to those components. Subsequently, upon task completion, the operator must disassemble the mechanism and stow it back inside the vehicle. In addition, the external mechanism's substantial weight and unwieldiness may necessitate additional personnel for its successful deployment.
[0007] In addition, these external mechanisms come with numerous drawbacks. They possess a fixed height, leading to limited reach, rendering them impractical for accessing elevated areas beyond their length. Moreover, their stability may be compromised, especially when utilized on uneven or soft surfaces, resulting in potential slips, trips, and falls. Additionally, operating these mechanisms may be physically demanding, causing strain on the operator's muscles and joints, particularly during prolonged use or when handling heavy objects.
[0008] Further, these mechanisms are ill-suited for handling substantial loads, making them unsuitable for lifting and transporting large or heavy items. Their usage necessitates significant floor space, potentially obstructing pathways and restricting access to other areas. Moreover, they are designed for single-person use, causing work processes to slow down and labour time to increase when multiple tasks require elevated access. The setup and repositioning of these mechanisms may be time-consuming, especially when various access points are necessary in diverse locations of the vehicle. As elevation increases, their stability diminishes, heightening the risk of accidents and falls. Misuse or overreaching on these mechanisms may result in accidents, injuries, and, in severe cases, even fatalities.
[0009] Furthermore, these mechanisms prove inefficient and tiring, for the operator, for tasks that demand frequent up-and-down movement or continuous access to elevated areas. Moreover, they lack load handling mechanisms, necessitating separate carrying of objects, thereby elevating the risk of falling items.
[0010] In light of the above stated discussion, there exists a need of an improved elevating and ascending mechanism (or external mechanism) for the vehicle to overcome the above stated disadvantages.
