The present invention is for designing and fabricating a Walking stick to support the elder people while climbing up and down the stair case and for the handicapped people who walk over a steep road.
Background of the Invention
Many research activities have been conducted across the world to find a working solution for the visually impaired. The major focus during designing a blind navigation system was put into obstacle detection system, staircase detection system, pit detection, etc. The basic understanding of a stick based navigation system can be understood by using a White Stick US2041334A. It basically operates through human touch sense and the orientation is achieved through performed navigation experiments or experience of environment in human memory US20070151587A1. The development of a sensor based walking stick can be traced to Smart Cane, a system basically working on the basis of environment as sensed by electronic sensors. A work at University of Paris developed a stick based system that detects obstacles or objects in front. It uses sensors for obstacle detection mounted on stick like ultrasound emitter/detector and laser. An audio feedback of intensity, inversely proportional to the distance to the nearest obstacle is provided by the stick. TOF (Time-of-Fly) between sensor and a nearest obstacle pointed by the user gives the distance. The shape of the whole obstacle is detected by its manual scanning. A work at University of Leeds, UltraCane, it was designed to offers only an assistance to the walking with overhanging obstacle detection using an ultrasonic obstacle detector. Ultracane transforms this information into vibrations which activate a thumb stimulating by buttons in the handle. A work at Canterbury University, K-Sonar, uses ultrasonic sensor for obstacle point-wised detection but it provides an audio feedback. The whole obstacle is reconstructed by the end-user from these pontificated points. K-Sonar does not provide assistance to orientation function US9468272B1. The GuideCane, a robotized stick, is designed to detect ground located specific obstacles such as upward stairs. The set of ultrasonic sensors located on a distal end of the smart stick transform acquired data into a vibrating feedback stimulating the end-user palm CN104799511A. The SmartCane, made at Indian Institute of Technology, detects knee-above obstacles using Ultrasonic sensor. It does not provide assistance to orientation. It is observed many times that when old people or handicapped people walk over the streets or while climbing up or down the staircase the stick slips and they may fall which hurts or injurs them US6595226B2. The crutches or the walking support devices which are in market cannot be used for staircase purpose and for walking in the streets CN201315923Y. As they are heavy and need to be carried. The height and the support which they provide cannot be adjusted. The crutches which are already available in the market has many limitations. To provide the extra support and stability for the walking stick and for the person the existing designs are modified and it is redesigned US9468272B1.

Summary of the Invention
In light of the above mentioned drawbacks in the prior art, the present invention aims to design and fabricate a new walking stick which will support the person more effectively while climbing up and down the staircase.
The specific objective of the invention is to design and fabricate a walking stick which will provide more support to the person and will be less weight compared to the existing model.

Detailed Description of the Invention
The design parameters are considered from the user requirements and the analysis. The design objective of the supporting walking stick is analyzed and the requirements for betterment are considered and the prototype on the basis of user characteristics is made. The major design and fabrication was done based on four requirements: user-friendly, useful functions, proper materials and elderly accessibility. The design analysis and the fabrication of the safe and handy walking stick also involve safety, reliability, applicative; the additional functions should adapt environmental and user characteristics. The basic design concept majorly focused on the life style of the elderly people and their walking and traveling conditions. It attempted to integrate the advantages of safety and comfort in traveling, adaptability, solidity and elegancy together.
A walking stick includes, not only a linear rod having a handle at the top end and a feet at the bottom end; a hand grip disposed in proximity to the top end of the linear rod; two or more supporting or extended and retractable self-level and load bearing feet at the bottom end of the rod will be provided; at least one adjustable leg or a sensor should be configured to detect a parameter of a walking surface; and a handle rest should be provided so that the user can rest his arm while climbing the staircase or walking through a uphill or downhill paths. If a controller along with a microprocessor and circuitry is included in the walking stick that will provide extra support and alert the user if there are any obstacles, the controller operably coupled to the two or more extendable and retractable self-leveling load-bearing feet and the at least one sensor and including circuitry configured to receive information regarding the detected parameter of the walking surface from the at least one sensor and circuitry configured to actuate at least one of the two or more extendable and retractable self-leveling load-bearing feet in response to the information regarding the detected parameter of the walking surface. In addition to the foregoing, other walking aid aspects are described in the claims, drawings, and text forming a part of the present disclosure.
The walking stick is divided into upper part and lower part. The upper part of the stick is arranged with an adjustable arm rest where the person using the stick can rest his arm on it. Depending on the height of the person it can be adjusted. The length of walking stick can be therefore adjustable as per user’s stature. The size of stick head was relatively larger so it was convenient for holding. The lower part of the stick head was designed as slip-resistant groove to prevent it slipping out of the hand. The lower part of the stick has an adjustable frame which can help [the person to climb down and up the stair case. It can be adjusted based on the case where the person climbing upwards or downwards. It is provided with a link so that it can be adjusted very easily without help of others.
A front light source was added on the stick. When the elderly walk at night with the stick, they can switch on the low beam or high beam in wake of actual environment thus reducing their accident incidence in dim places. The handle and the arm rest portions of the walking stick for the elderly walking adopted plastic material as the weight of the stick should be limited and the gripping support should be high and the body is made of metal maybe aluminum alloy. The overall weight of the walking stick should be so light that the elderly people, handicapped people and the pregnant women can save effort when they use it. Moreover, the major part of the stick is made of metal material which will provide secure support while walking and its foot pads will be provided with anti-slippery rubber materials so that it gives extra grip and to increase friction. The overall weight of the stick is confined to light weight so that the user will feel comfortable and easy to handle. Its general modeling was simple and steady.

The walking stick designed is to provide extra support to the elderly people or for handicapped compared to the crutches and the common walking sticks available in the market. More options can be included in the walking stick to make it much supportive and adaptive. The cost of the current walking stick can be minimum and can assist the person more effectively than a normal one.
