1 TARIFF THE ACTIONS OF ELDERLY INDIVIDUALS SITTING DOWN AND STANDING UP FROM CHAIRS ASSISTIVE ARM SUPPORT DEVICE ARMREST STRUCTURE Technical Area The invention is an armrest that assists elderly individuals in sitting down and standing up from chairs. It relates to the armrest design with attachments. The invention is particularly relevant to the use of seating by elderly individuals and those with physical limitations. to eliminate the difficulties they experience in sitting and standing, and to reduce the risk of falls, to increase their independent mobility and improve their quality of life It relates to the armrest design. 10 State of the Art Designed to facilitate daily living activities for elderly individuals. Furniture is developed taking ergonomics and anthropometric measurements into account. Nowadays, seating designs for elderly individuals generally focus on seat height. It appears that the focus is on the features of the seat and backrest. These designs include 15 The main goal is to increase user comfort and facilitate daily life activities. It has been determined as follows. In today's furniture market, single armchairs include: bergere chairs, recliners, and recliners. They are also known by various names such as television chairs. The common feature of these chairs is... 20 allows users to spend time comfortably and relaxed while sitting for extended periods. These are the things they provide. Comfort and convenience are prioritized during prolonged sitting. Because of this, these seats are usually supported with foam padding and They are covered with soft fabrics. When examined from an anthropometric point of view, the seats to ensure comfortable use for individuals with different physical sizes Compared to regular chairs, they are designed to be wider, lower, and have armrests. This design is 25 This approach gives the seats a cruder form and makes them heavier than chairs. It forms a structure. The heavy structure of the seats poses a risk of tipping over if force is applied while leaning on them. This reduces the need for support, especially during sitting and standing movements. Because it provides advantages for elderly individuals who need it, it is more preferred by the elderly. 30 2 This is being observed in elderly individuals, due to age-related physiological changes and physical fatigue. They often feel the need to sit down because of this. However, the available seats have low seating. Its height and soft foam structure facilitate sitting and standing activities for elderly individuals. It makes things more difficult. Elderly individuals can usually get up from chairs by leaning forward and reaching for the armrests. They need to support themselves with both arms. During this movement, the lower back and knees are strained. Overloading occurs, balance can be lost, and there is a risk of falling. This is increasing. Most elderly people are affected by fear of falling and lack of muscle strength. It takes some time and several attempts before they can sit or stand up. In some cases, it is necessary to get support from people around you to complete these activities. They are forced to take these seats. Due to these difficulties, elderly individuals cannot use the available seats. They frequently complain about their designs. According to research, accidents in old age increasingly lead to disability. It is a cause of death and ranks sixth among causes of death. Statistical data shows that home accidents account for 82% of accidents among the elderly. This shows that the frequent causes of these accidents include acute and chronic diseases. age-related physiological changes and physical disabilities (forgetfulness, easy fatigue, (such as vision problems and frequent dizziness). Studies have shown that home accidents The study reveals that the most common type of accident is falls. Current furniture designs fully meet the physiological and ergonomic needs of elderly individuals. The inability to respond in this way is leading to an increase in falls at home. Especially soft, low and deep seating surfaces facilitate the act of sitting and standing. This makes it more difficult and increases safety risks. In the literature, seats for the elderly... factors such as seat surface firmness, seat height, and backrest angle are considered in their designs. Although there are studies that have examined it from an ergonomic point of view, sitting and standing 25 shortcomings in integrated mechanisms to facilitate its activity It is seen. In contemporary furniture designs, the anthropometric measurements, muscle strength, and other characteristics of elderly individuals are taken into account. Taking mobility into account, supporting safe and independent use. The development of designs is of great importance. With the current technology, elderly individuals 30 Modification of armrest structures to facilitate sitting and standing movements, adjustable seat height and balance support elements Solutions such as integration are theoretically proposed. However, these proposals... 3 in terms of transforming them into practical, economical and aesthetic designs There are shortcomings. To reduce the risk of falls and injuries in elderly individuals, identify the causes of falls within the home. redesigning existing furniture and eliminating space-related issues The necessity is clear. In this context, meeting the physiological needs of elderly individuals, 5 ergonomically suitable, safe and at the same time aesthetic furniture designs Its development is of great importance in terms of the health and quality of life of the elderly. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to the inadequacy in this area, it is necessary to create a new model in the relevant technical field. It has been made. 10 Purpose of the Invention The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem. The invention addresses the needs of elderly individuals and people with physical limitations who frequently encounter challenges in their daily lives. the difficulties they encountered, the challenges they experienced while sitting down and getting up from the existing seat designs, and 15 It aims to eliminate security risks. In the known state of the art. As explained, elderly individuals tend to lean forward when sitting down or getting up from chairs. They have to lean on the armrests for support, which puts excessive strain on their lower back and knees. their lives and the risk of losing balance and falling are due to the current seats This reveals the inadequacy of their designs. Solving these problems is crucial. 20 The invention, developed for this purpose, will facilitate the user's sitting and standing movements. a mechanism that will reduce the risk of falling and increase independent mobility It presents. The main purpose of the invention is to reduce the number of items used by elderly individuals in their homes. to prevent falls resulting from, this user group's independent movement from the furniture and to ensure they can benefit from it safely and improve their quality of life. 25 The invention differs from the conventional way of sitting and standing from the front, as it allows the user to sit from the side. It includes an adjustable armrest mechanism that allows for easy sitting and standing. This The mechanism allows access to the seat with a movement similar to getting in and out of a car, elderly people who have difficulty controlling their speed and balance, especially when moving forward It aims to reduce the risk of falls for individuals. 30 4 Another aim of the invention is to functionally utilize the force applied by the user to the armrest. By evaluating this in this way, this force becomes an element that assists in sitting and standing movements. The goal is to transform it. For this purpose, a spring is placed inside or on the front of the metal frame of the armrest. The armrest device transmits the pressure force applied by the user to the floor, thus facilitating sitting and... It provides support to the user during standing actions. Thanks to its spring mechanism, 5 The softened force is transferred to the ground via the lower foot (shoe) that contacts the ground. is transmitted, thus helping the user to take off in a balanced and safe manner. is happening. Another aim of the invention is to enable elderly individuals to live independently without external assistance. The aim is to enable them to perform daily living activities. The current number of seats is 10. In their designs, elderly individuals often get up from the seats while being surrounded by people. They have to ask for help, which negatively affects their self-confidence, and This restricts their social lives. With this invention, elderly individuals can live without external support. being able to sit and stand safely without fear of falling is intended. 15 Although the target audience for this invention is primarily elderly individuals, the developed mechanism Individuals with disabilities, patients with temporary physical limitations, and all those experiencing physical challenges It is designed so that it can also be used by individuals. This allows the invention to have a wide range of applications. It caters to a specific user group and supports universal design principles. To achieve the purposes described above, the invention is designed to benefit elderly individuals and those with physical disabilities.

This is done to help better understand the subject. 5 The invention helps elderly individuals and those with physical limitations to get in and out of seats. developed to alleviate the difficulties they experience and reduce the risk of falls This relates to a functional armrest configuration (A). This configuration allows elderly individuals to sit in the chair. an extendable armrest mechanism that provides side access and ground support It includes a spring-loaded power transmission system. 10 The tube (1), which is one of the basic components of the armrest structure (A), is the outer part of the inner shaft (2). It provides protection. The inner shaft (2), made of ST37 metal material, is the main shaft of the system. It is the supporting element on which the handle (7) sits, the spring (6) is positioned and the bottom It functions as the shaft to which the foot (4) is attached from below. The lower foot (4) is attached to the inner shaft (2) The fixation is carried out with the help of the fixing segment (3). 15 The lower foot (4) transfers the force applied by the user to the handrail (7) to the ground. It is a component that provides balanced support. The bottom foot (4), made of non-slip plastic material, also in terminating the lateral movement of the armrest structure (A) It plays a role. The force applied to the handle is transmitted to the lower leg via the internal mechanism, and Thanks to its non-slip structure, it prevents the armrest from opening further to the side. This 20 Thanks to this, the foldable armrest system can be used safely. The cover (5) has an important function within the armrest structure (A). Inside it The inner shaft (2) is connected to the handle (7) by passing the screw end through the hole. Thanks to the O-ring (11) placed inside the lid (5), the handle (7) can rotate 360 ​​degrees. It has this feature. This rotational capability allows for support in different hand positions. 25 It makes things easier. The spring (6) receives the force applied by the elderly individual to the handle (7) through the inner shaft (2). The lower leg (4) pushes towards the floor. This mechanism applies the user's armrest It maintains balance by transferring the force to the ground in a controlled manner. 7 A handrail (7) is a support on which an elderly person can rest their arm and get support when sitting or standing. It is the top piece. With its ergonomic design, the inside allows for a comfortable grip of the fingers. The finger joints are formed in a wavy pattern on the part. On the lower part, the inner shaft (2) It has holes for screw mounting. The frame (8) is the metal profile part that forms the inner casing of the movable armrest of the seat. 5 The dimensions of the frame (8) can be changed to match the design and dimensions of the seat. It is of a quality that allows it to be adapted to different seat models. The wheel (9) that enables the sideways movement of the armrest structure (A) of the frame (8) It is placed underneath. The armrest can move freely for 360 degrees. It is selected with a rotatable feature. A wheel is placed on both the front and rear of the frame (8). (9) is installed. The wheel (9) is connected to the frame (8) by means of a nut (10). is provided. The O-ring (11) placed between the inner shaft (2) and the cover (5) allows the handle (7) to rotate 360 ​​degrees. By enabling it to rotate, it allows the user to receive support from different angles. He knows. 15 The hinge (12) ensures that the rear edge of the frame (8) is attached to the seat and the armrest The structure (A) enables rotational movement centered on this edge. This rotating movement allows the elderly individual to access the seat from the side. It makes things easier. The magnetic plate (13) is positioned on the frame (8) and the side surfaces of the seat. 20 When the armrest mechanism (A) is in the closed position, the magnetic properties of the plates This ensures stability. Thus, the armrest remains stable when not in use. It remains in that position. The subject of the invention is the armrest design (A), which is a combination of the elements detailed above. It was created by introducing this structure. This arrangement allows elderly individuals to access the seat from the side. 25 providing a functional effect by applying force during sitting and standing movements. It offers a solution that transfers the water to the ground in this way, significantly reducing the risk of falls. The invention can be integrated into different seat models according to the user's needs. and elderly individuals, as well as all individuals with disabilities, illnesses, and physical challenges. Suitable for use. 30 The assembly principle of the invention is as follows: 8 First, the frame (8) was made by welding steel box profile with dimensions of 20x20x2 mm. The wheels (9) are mounted in the middle of the tensioners at the bottom of the frame (8). Holes are drilled for this purpose. The positioning of these holes determines the armrest. to ensure that (A) of its structure moves in a balanced manner It should be planned. After the frame (8) is prepared, the wheels (9) are assembled. 5 The wheels (9) are threaded through the tension holes at the bottom of the frame (8) and fitted with M8 nuts. It is fixed by tightening (10). This fixing process ensures that the armrest structure (A) is properly aligned. It allows it to move and has sufficient load-bearing capacity. In the next step, a 1-inch steel pipe (1) made of ST37 material is welded. It is mounted to the frame (8) as shown. The mounting position depends on the requirements of the seat design. 10 It is adjustable according to requirements. If desired, the armrest configuration (A) and the seat can be adjusted. Depending on its design, it can be positioned in front of or to the side of the frame (8). Pipe (1) After it is assembled, a steel spring (6) is placed inside. The spring (6) is attached to the armrest of the user. It transmits the force it will apply to the ground in a balanced way. The spring (6) into the pipe (1) Correct placement is important for the proper functioning of the system. Steel 15 After the spring (6) is placed, the inner shaft (2) made of ST37 material is inserted into the pipe (1) It is attached and seated on the spring (6). The inner shaft (2) is the main load-bearing element of the system and is attached to the spring (6). By interacting, it transmits the force applied by the user to the lower leg (4). After the inner shaft (2) is installed Then, the retaining ring (3) is placed at the bottom. The retaining ring (3) is attached to the inner shaft (2) It is a component that connects to the lower foot (4). The segment (3) must be correctly 20 The placement of the fixing segment (3) is important for the safety of the system. The bottom foot (4), made of plastic material and with an M6 mounting point, is mounted underneath. The lower foot (4) makes contact with the ground when the elderly person applies force by leaning on the handrail (7). It is the part that provides balance. Being made of non-slip material ensures safety. It is important for use. 25 In the next step, by fitting the O-rings (11) to the cap (5), the pipe (1) with M32 screw size It is joined by screwing. O-rings (11) allow the handle (7) to rotate 360 ​​degrees. It allows the user to receive support from different perspectives. In the final stage of the assembly process, the screw at the end of the inner shaft (2) passing through the cover (5) The topmost handle (7) is attached to the tooth. Thanks to this connection, the handle (7) is attached to the inner shaft (2) 30 It can rotate 360 ​​degrees on it. The handle (7) is ergonomic. The design is important so that the user can easily grasp it. 9 After the invention is assembled, the outer part is covered with foam to match the seat model. and can be covered with fabric, thus giving it an aesthetic appearance. Armrest In order for configuration (A) to be usable, the armrest to which it is mounted must be tilted to the side. It needs to be opened. For this mobility, the armrest is attached to the seat frame like a leaf. It must be connected with hinge (12). Hinge (12) enables the armrest to rotate, 5 It facilitates the elderly individual's access to the seat from the side. Additionally, the armrest is not in use. Magnetic plates (13) on the inner surface so that they can be fixed to the seat surface at times These magnetic plates (13) must be mounted on the armrest mechanism (A) closed. It ensures that it remains stable in its position.
