Description

Technical Field

[0001] The utility model relates to the field of assistive chairs, in particular to a novel assistive chair. Background Art

[0002] In daily life, the elderly or people with bad lumbar spines may find it extremely difficult to stand up from a chair. Since the seat cushion structure of a conventional chair is fixed and inconvenient to assist with leverage, the elderly need to rely on the support of others to stand up after sitting down. When there is no one to accompany them, standing is very inconvenient and has disadvantages. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a new type of assistive chair which is comfortable to lean on and easy to move and can be used in a variety of environments, such as indoors or outdoors. The utility model also provides a new type of assistive chair which is comfortable to lean on and easy to move and can be used in a variety of environments, such as indoors or outdoors. The assistive structure is added to provide a pushing force for the elderly to stand up, so that the elderly can lean their center of gravity forward and stand up conveniently.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A new type of assisted-lifting chair includes a seat, casters with brakes, an electric push rod, a front seat cushion, a rear seat cushion, a movable rocker arm, a bottom fixed bracket, and a front fixed bracket. The lower part of the seat is connected to a plurality of chair legs, the bottom of the chair legs are connected to casters with brakes, the upper part of the seat is connected to a chair back, push rods are connected to both sides of the chair back, the outside of the chair back is connected to a cushion, both sides of the chair back are connected to vertical guard plates, the inner side of the vertical guard plates is connected to the seat, the upper part of the vertical guard plates is connected to armrests, and a control button is provided at the lower part of the armrest. The seat has a reinforcement rod, a mounting plate is provided in the middle of the reinforcement rod, the mounting plate is rotatably connected to the electric push rod through a lower shaft rod, the electric push rod has an output rod, and the output rod has a connecting plate. The middle part of the seat has a through hole, the electric push rod is adapted to the through hole, and the electric push rod passes through the through hole.

[0006] The utility model discloses a chair seat with an upper part connected to a bottom fixing bracket, the bottom fixing bracket is connected to a lower fixing ring, the lower fixing ring is rotatably connected to a lower end of a movable rocker arm, the upper end of the movable rocker arm is rotatably connected to an upper fixing ring, the upper fixing ring is connected to a rear cushion, the rear cushion is connected to a front cushion via a hinge, the front cushion is connected to a front fixing bracket, the front fixing bracket is rotatably connected to the bottom fixing bracket via a movable shaft rod, the front fixing bracket has a connecting ear, and the connecting ear is rotatably connected to a connecting plate via an upper shaft rod. Beneficial Effects

[0007] The front seat cushion, the rear seat cushion, the movable rocker arm and the electric push rod cooperate with each other to form an assisting structure. When the elderly person needs to stand up, the control button can be pressed to start the electric push rod to rotate upward until it passes through the through hole, and the front seat cushion can be pushed outward by driving the output rod, so that the rear seat cushion is forced to be linked and rise upward, providing a pushing force for the elderly person to stand up, so that the elderly person's center of gravity tilts forward and it is convenient to stand up. After the elderly person stands up, the electric push rod drives the output rod to retract inward, and the front seat cushion is pulled back inward by the retracting force of the output rod, and the movable rocker arm drives the rear seat cushion to rotate inward and reset to a flat state between it and the front seat cushion, and the electric push rod rotates downward and passes through the through hole to be stored in the lower part of the seat.

[0008] The movable rocker arm of the utility model increases a connecting fulcrum between the rear seat cushion and the bottom fixed bracket, and limits the upward rising height of the rear seat cushion to prevent the rear seat cushion from flipping upward, thereby improving the safety of the device. The movable rocker arm, the rear seat cushion, the front seat cushion, and the bottom fixed bracket are linked to each other to form a parallelogram shape. The parallelogram has the characteristics of instability and easy deformation, which can increase the flexibility of the linkage between the components of the power-lifting chair for assisting in lifting and resetting.

[0009] The utility model provides a power-assist chair with soft cushions on the back and the seat, which improves the comfort of leaning on by the user, and cooperates with the push rod and the casters with brakes to increase the convenience of moving the power-assist chair, which is convenient for pushing the elderly with limited mobility and can be used in various environments indoors or outdoors. Vertical guard plates are added on both sides of the power-assist chair to prevent the elderly from slipping off the seat, which increases the protection for the elderly. The armrests on the upper parts of the vertical guard plates are convenient for the elderly to grasp and provide a force fulcrum for the elderly to support and borrow when standing. The control button added at the lower part of the armrest drives and controls the power-assist structure of the device through the circuit, which is convenient to operate.

[0010] The utility model is comfortable to lean on and easy to move, and can be used in a variety of environments, whether indoors or outdoors. By adding an assisting structure, a pushing force is provided for the elderly to stand up, so that the elderly's center of gravity leans forward and it is convenient for them to stand up.
