Abstract

Page 1 of 1. Summary of the Invention: The invention of the muscle stretching training chair for children with cerebral palsy aims to rehabilitate physical abilities related to the movement of large muscle groups in the shoulders, legs, knees, ankles, elbows, fingers, and arms. It allows for independent vertical movement of both arms, and forward and backward movement of the feet. With consistent practice, this chair helps children with cerebral palsy use weakened limbs, relieves stiffness and muscle tension in the arms and legs, and reduces finger locking. This leads to improved self-reliance and a better quality of life, enabling children to participate in daily activities independently and become less of a burden on society. Furthermore, it serves as a medium to stimulate and enhance learning and develop physical, mental, intellectual, and social skills. The muscle stretching training chair for children with cerebral palsy is constructed using cutting and assembling wooden parts according to a specific design. The chair's structure is made of interconnected wooden pieces. The main structure consists of a frame in the center that holds the seat. Below the seat is a footrest with a spring, which children can use to extend and retract the footrest by applying force. Behind the seat is a wooden platform with elastic resistance bands, and a handle that can be moved up and down to operate a pulley system, helping to train hand and arm muscles.

Revised 16/10/2018, Page 1 of 1 page. Claims 1. The cerebral palsy stretching training chair consists of a main frame base (2) in which the middle of the main frame base (2) has a frame that holds the chair (3), which has a seat (4) underneath which is a footrest (5) and a spring (6) which the child can step on to extend and retract the footrest (5). Further back from the seat (4) is a set of wooden platforms holding the stretching rubber (7) which has a set of handles (8) that can be rocked up and down to control the pulley set (9) to work in order to train the strength of the hand and arm muscles. It has a specific design as follows: The main frame base (2) has two pieces of long wood (10) made of rectangular cross-section wood and two pieces of short wood (11) made of rectangular cross-section wood, which are assembled into a rectangle. The chair frame (3) consists of two wooden legs (12) that determine the height. At the top end of the legs, grooves (13) are made for attaching the chair frame beams (14). The ends of the chair frame legs (12) are attached to the center of the long side of the wood (10) which is part of the main frame base (2). The seat (4) is attached to the chair frame (3) and consists of a backrest (15) and a seat (16) made of two round cross-section pieces of wood joined together, and armrests (17) attached to the sides of the seat (4) on both sides. Below that is a footrest (5) for stepping on, and in the footrest (5) which is mounted under the seat (4) there is a spring (6) which the child can use to extend and retract the footrest (5) by pressing down on it. The rubber stretching mechanism (7) is located on top of the device. Attached to the chair frame (3) is a pulley assembly (9) at the top of the device, followed by a handle assembly (8) with a wooden handle (18) for gripping and pulling the elastic (19) to stretch it. At the midpoint is a wooden leg of the handle assembly (20) attached, and at two-fifths of the length of the handle assembly leg (20) there is a wooden handle assembly joint (21) attached with a nut, one end of which is attached to the plywood handle assembly beam (22) attached to the chair frame (3). Below the handle assembly beam (22) is a wooden support (23) with the other end attached. At the center of the wooden table (24) is a piece of plywood attached to the back of the backrest (15), and at the bottom of the wooden table (24) there are two table legs (25), one on the left and one on the right, attached between the outer corners of the wooden table (24) and the chair frame (3). On the wooden table (24) there is an elastic band (19) that runs through a pulley set (9) and a handle set (8). This device allows the child to exert force to control the handle set (8) to rock up and down, practicing the strength of the hand and arm muscles. ---------------------------------------------------------------------------------------------------- Page 1 of 1 page Claim 1. The cerebral palsy stretching training chair consists of a main frame base (2) in the middle of which is a frame that holds the chair (3), which has a seat (4) underneath which is a footrest (5) and a spring (6) which the child can step on to extend and retract the footrest (5). Further back from the seat (4) is a set of wooden platforms with elastic bands (7) which has a set of handles (8) that can be moved up and down to control the pulleys (9) to work in order to train the strength of the hand and arm muscles. It has a specific characteristic: the main frame base (2) has two long pieces of wood (10) made of rectangular cross-section wood, 1 x 2 inches in size, approximately 80 centimeters long, and two short pieces of wood (11) made of rectangular cross-section wood, 1 x 2 inches in size, approximately 40 centimeters long. Then all the wood is assembled together to form a rectangle. The chair frame (3) consists of two wooden legs (12) that are approximately 180 centimeters long, which determine the height. At the ends of the legs, grooves (13) are made to hold the long side (10) of the base at the 1/2 position. Another piece of wood, the same length as the width of the main frame base (2), is used as the chair frame beam (14) and fits perfectly into the grooves (13). The main frame base (2) and the chair frame (3) are then assembled. The seat (4) is attached to the chair frame (3) and consists of the backrest (15) and seat (16), made of two round cross-section pieces of wood joined together, and armrests (17) attached to the sides of the seat (4) on both sides. Below this is a footrest (5) for stepping on, and in the footrest (5) which is installed under the seat (4) there is a spring (6) that a child can step on to extend and retract the footrest (5). A wooden stretcher (7) is located on top of the device, attached to the frame that holds the chair (3). At the far end of the device is a pulley (9). Below that is a handle (8) with a handle (18) made of a piece of wood about 20 centimeters long for gripping to pull the elastic (19) to stretch it. At the midpoint there is a leg of the handle (20) made of a piece of wood about 80 centimeters long attached to it, and at the position about 2/5 of the handlebar assembly legs (20) have a handlebar joint (21) made of a piece of wood about 30 centimeters long, held in place by a nut. One end is attached to the handlebar beam (22) made of a rectangular piece of wood attached to the chair frame (3). Under the handlebar beam (22) there is a support beam (23) made of a piece of wood about 60 centimeters long, with the other end attached to the center of the wooden table (24) made of a piece of wood about 35 centimeters long and about 20 centimeters wide, mounted behind the backrest (15). At the bottom of the wooden table (24) there are two table legs (25), one on the left and one on the right, attached between the outer corners of the wooden table (24) and the chair frame (3). On the wooden table (24) there is an elastic band (19) that runs through the pulley (9) and the handlebar (8). This device allows children to exert force to control the handlebar (8) to rock up and down, practicing the strength of their hand and arm muscles.
