Description

Counterweight lever up seat

This creation is related to the technical field of assistive products, especially a seat equipped with a lever to get up, which uses the body weight when getting up to drive a pair of movable handles. At the same time, it is matched with a pair of reorganization to adjust according to the user's weight to link a chair cushion. Flip up to reduce the applied force and assist the user to get up.

According to, chair is a kind of furniture that provides sitting posture to bear the weight of the human body, but in the process of getting up from sitting posture back to standing posture, the user must use the large muscle groups of the whole body to get up. For the elderly or users with limited mobility In terms of getting up from the chair, it may be difficult.

Up to now, the population over 65 years old in the country has reached more than 15%, which has officially entered the standard of the elderly society. Therefore, the demand for assistive products is also increasing. Regarding the most frequent movements in life, the ability to sit and get up is of great importance to the daily life of the elderly, and it has also become a basic condition for judging whether they can live independently. According to the Ministry of Health and Welfare’s assessment of six personal activities of daily living for people over 65 years of age, the rate of difficulty in bathing was 10.98%, followed by the rate of getting in and out of bed or chair at 10.18%. However, the use of appropriate assistive devices can help the elders’ daily routines. Life is more independent, especially the movement of getting up from the chair is the process of changing the center of gravity from the sitting position to the standing position. Because the area of support at the moment of leaving the seat is reduced, and the body still needs to resist gravity to move forward and upward, and it requires bilateral muscles. Sufficient strength and coordination can be completed, so leaving the seat is usually considered to be the key point in the sit-to-stand movement.

At present, scholars divide the stand-up movement into different stages. Generally speaking, it is divided into two to four stages. There are three main methods of distinguishing: "Pre-extension period" or "preparation period", after leaving the seat is the "extension period" or "uplift period". The torso leans forward during the period of straightening to make the body mass produce horizontal linear momentum, which is converted into vertical momentum during the straightening period. , Push the body to a standing posture; 2. The three-stage method. The first stage is the "displacement stage", which is mainly the eccentric contraction of the dorsal spinal muscles to make the trunk and pelvis tilt forward. The second stage is the "transfer stage" which is mainly the center of gravity. Forward and upward at the same time. During this period, you need to have good dorsal spines, quadriceps, biceps and gluteus maximus. In the third stage, you need to keep the trunk and knee joints in an upright posture to maintain stability. ; 3. The four-stage differentiation method. The first stage refers to the stage where the trunk "leaps forward", the hip joint is bent, and the body's center of gravity moves forward and downward. The second stage refers to the stage where the knee is slightly straightened before leaving the seat, and the third stage After leaving the seat, the hip, knee and ankle joints are stretched. The fourth stage is the stage where the trunk and lower limbs adjust their posture and maintain balance. In view of the above theories, how to develop a more ideal and practical innovative structure in view of the problems in the traditional chair structure is what consumers are eagerly awaiting, and it is also the goal and direction that the relevant industry must strive to develop and break through.

Therefore, the creator used the above theory and design practical experience to finally design a counterweight lever up seat, allowing the elderly to easily use their own weight when they get up to drive a pair of movable handles, and combine it with a pair of handles. It is adjusted according to the weight of the user, and the movable handle links a chair cushion to turn upwards to assist the user to get up, which greatly reduces the difficulty of getting up, and is very helpful for the elderly to live independently.

One of the purposes of this creation is to provide a counterweight-type lever stand-up seat, which uses a movable handle, a movable frame and a pair of reorganizations. The movable frame drives the chair cushion to turn up to assist the user to get up; and In addition, when used with the combination, the weight can be adjusted according to the weight of the user, so that the movable frame is more labor-saving when it is pressed down, thereby achieving the effect of reducing the difficulty of getting up.

In order to achieve the above-mentioned purpose, the weighted lever-up seat of this creation includes: a fixed chair frame in which a seating space is formed, and the front side of the fixed chair frame is provided with a pair of first chair legs in parallel and spaced apart from each other. A pair of second chair legs are arranged on the rear side in parallel and spaced apart. The length of the second chair legs is greater than that of the first chair legs. A pivot bracket is connected between the two chair legs; a chair back is arranged at the top of the pair of second chair legs, and two sides of the chair back are respectively provided with a first pivot joint; a movable frame, which is A rectangular frame-like structure formed by a pair of pivotal arms on two sides, a first frame on the front side, and a second frame on the back side, and the middle section of each pivoted arm is movably and pivotally connected, respectively In each pivoting bracket, the movable frame can swing back and forth in the seating space; a pair of movable handles, the rear side of each movable handle is corresponding to the first pivoting portion and is provided with a second pivoting portion , And the front side of each movable handle is provided with a third pivotal portion, each of the second pivotal portions is pivotally connected to each of the first pivotal portions, and the third pivotal portion is pivotally connected to the The two ends of the first frame; a chair cushion whose front side straddles the front side of the fixed chair frame, and the back side of the chair cushion is connected to the second frame; It is composed of hanging weights. Each hanging weight is provided with a hook corresponding to the first frame for hanging on the first frame to adjust the weight of the user; when the user wants to get up At the same time, the body weight is used to lean against the pair of movable handles, and at the same time, the matching structure is adjusted according to the user's weight to link the chair cushion to flip up, so as to reduce the applied force and assist the user to get up.

In one embodiment, each pivoting bracket of this creation is provided with a plurality of first pivoting holes, and the first pivoting holes are arranged at intervals for adjusting the mounting position of the pivoting arm to adjust The starting angle of the activity frame. Furthermore, the length of the first frame and the second frame is greater than the width between the two pivoting brackets, so that when the chair cushion is naturally pressed down, the first frame and the second frame are divided Do not lean against the two pivotal brackets to form a positioning. In addition, two mounting holes are provided under the two sides of the chair back to correspond to the two second chair legs, so that the chair back can be sleeved and fixed to the two second chair legs, which greatly improves assembly and subsequent maintenance. Convenience.

In another embodiment, each movable handle of the present creation includes an armrest and a linkage rod, the second pivot part is located at one end of the armrest, and the other end of the armrest is connected with one end of the linkage rod, and The third pivotal portion is located at the bottom end of the linkage rod, and the linkage rod is a curved structure, so that when the movable handle is actuated, the linkage rod will not rub against the fixed chair frame.

In yet another embodiment, the weighted lever-up seat of the present creation further has an inclined pedal, which is arranged under the fixed seat frame and corresponds to the position of the first chair leg, so that the inclined surface of the inclined pedal faces forward , In order to step on it to make the user's body lean forward slightly, making it easier to get up.
