Description

The present invention uses a picking margin that can be picked by a child of infancy to school age, and plays with a plurality of balls with different amounts of filling, so that it can be grasped by a hand (fingertip), muscles such as picking Play equipment that can develop the overall motor skills such as neck, shoulders, upper arms, elbows, wrist joints, etc. by throwing movements, and can develop the fine motor skills, and can be used for rehabilitation of adults and persons with disabilities About.

  In recent years, in addition to urbanization and the declining birthrate, it has become a car-centered lifestyle, and children's ability to play outside has drastically decreased. In addition, the number of video games has increased dramatically, and with the push of a button, the strength of the fingertips does not enter and the muscular strength for gripping and picking is reduced, and the adjustability is not improved, so the clumsiness of the hand has been pointed out. Therefore, in indoor games, there is a need for a playground equipment that can promote the overall development of fine motor skills such as fingertips and coarse motor skills such as hands and arms.

  Speaking of childhood to school-age children's ball play, there are various sizes and materials, such as those made of rubber, wood, vinyl, leather, cloth, etc. The motor functions promoted by playing with various balls include responsiveness, rhythm, sensitivity, accuracy, and dexterity. So far, fabric balls have been devised to catch balls in a room or small space, or to handle easily for playing alone. For example, spheres for volleyball, basketball, and handball are used, and materials include cloth, rubber balloons, and soft hollow rubber balls. In general, the balls made of cloth are made of cotton as a filling material and filled with batting, so they are completely spherical and can be thrown using the entire palm or all fingers. Although it does not cause inconvenience, it is not suitable for handling like picking.

  The fingertips of toddlers and children grow up with play such as beanbags, hajiki, and solo spinning, and the tactile sensation develops as the hands grow older. A beanbag containing cereals such as red beans in a cloth bag was effective in promoting the movement of fingers and arms. However, in recent years, the penetration rate of these playground equipments is low, and beanbags, hajiki and self-playing are not safe as playground equipment from about 1 year old, and hygiene is also poor. The materials and structures of playground equipment in early childhood are hygienic and require durability and safety.

  The hand (fingertip) is a source of knowledge that fosters creativity, and the ability to think develops with the hand (fingertip) and is said to lead to brain activation. The fingertip is trained by repeating the actions of “gripping” and “pinching”, and the fine motor ability develops. At the same time, it is also important to develop the coarse motor ability by moving the neck, shoulders, upper arm, elbows and wrist joints to train the muscles of the arms. Based on these, it is required to develop playground equipment that can develop the overall development of hand (fingertip) fine and coarse motor skills through parent-child and group games.

As disclosed for fingertip sensation development and rehabilitation, the gripping ball of Patent Document 1 is of a size that can be grasped in the palm, and the structure is filled with rubber-like bullets in a bag, which is a dense stretch that is soft to the touch. It is covered with a decorative outer bag made of cloth, and is effective for training to improve fingertip sensation, finger muscle strength, and group play for young children. Further, it has been pointed out that by attaching a protruding portion to the outer bag, the palm is stimulated to assist the gripping force that is insufficient when the function of the fingertip is rehabilitated. The outer bag is said to be familiar to the palm.
However, the material is special and difficult to obtain, and it takes a lot of time to make a filling because of the double structure. The inner balloon is not durable enough.

The game ball disclosed in Patent Document 2 has a shape other than a spherical shape such as a heart shape and a polygonal shape, and has been disclosed with the first focus. It does not fly far when thrown, secondly it is difficult to roll, it is difficult to roll far, thirdly there is little impact when it hits the human body etc., and it is less likely to repel and bounce Appropriate weight is 62 g. However, picking it with your fingertips does not promote development.

As disclosed for indoor play and rehabilitation exercises for the sick, the low elasticity ball for play of Patent Document 3 has a structure having a recess and is easy to pick because a finger fits into the recess. The size can be selected according to the subject. Soft and low-elasticity material is used so that it will not play too much when hitting a door or glass window, and will not be injured even if it hits the forehead strongly. However, since it has a structure in which twelve pieces of mandarin orange fruit formed are combined, it takes a very long time to manufacture. There seem to be many processes to make by hand, and durability is inferior.

  The ball-shaped training playground equipment of the present invention has the following effects as a result of solving the above-mentioned problems by the above-mentioned means.

  Conventional balls are manufactured with the consciousness of a perfect sphere, so there is no pinch that can be picked with a fingertip. When the ball-shaped training playground equipment is larger than the user's hand, the shape of the ball-shaped training playground equipment of the present invention is a cubic octahedron, and there is an appropriate grip angle of 90 degrees. The structure is easy to hold. The muscle can be trained by adjusting the filling level of the ball-shaped training playground equipment. The ball-shaped training playground equipment is different from the ball-shaped training playground equipment in which the filling degree is different from the ball-shaped training playground equipment that can freely adjust the filling degree according to the size of the user's hand, muscle strength to pick, muscle strength to grip, and muscle strength to throw by hand arm. This is a ball-shaped training playground equipment. A particularly preferred filling material is 100% polyester cotton, and a ball-shaped training equipment having a filling amount of 50 g can be played from around 1 year old when the object can be picked with a fingertip. Beginning with the delivery of ball-shaped training equipment, you can gradually develop your overall motor skills such as fingertips, hands, wrist joints, shoulders and neck. You can train your strength by repeating throwing, kicking and playing indoors. Moreover, the ball-shaped training playground equipment of the filling 50g can be picked not only by a hand but also by a toe. The ball-shaped training equipment is light and easy to handle, has a soft and comfortable feel, and leads to mental stability. There are three types of picking methods, including one fingertip picking, two finger belly picking, and three side picking, which can be applied to any picking method, and can promote the development of muscle strength of the fingertips according to the stage of development. The ball-shaped training playground equipment of 100 g and 150 g of filling is heavier than the ball-shaped training playground equipment of 50 g of filling and has elasticity, so it requires muscle strength when grasping or picking, and it can improve muscle strength by repeating it many times. Can do. Since the ball-shaped training playground equipment with 200 g of filling cannot be picked or grasped, it is thrown with both hands. By repeatedly playing with a plurality of ball-shaped training playground equipment with different filling degrees, the development of comprehensive motor skills such as fingertips, hands, arms, neck, shoulders, elbow joints, etc. is promoted. The play spreads by selecting an appropriate ball-shaped training playground equipment from a plurality of ball-shaped training playground equipment in which the filling degree can be freely adjusted according to the state of the child's muscular strength or a different degree of filling. The ball-like training playground equipment with 50 g of filling is not dangerous even if it hits a door or a glass window, and even if it hits the face strongly, there is little impact, so you can enjoy playing with the ball actively. Ball-shaped training playground equipment is the best ball for infants to meet for the first time. Due to its elastic recovery, it is hard to lose shape over a long period of time and has excellent durability and can be washed. Throwing and kicking can be enjoyed even by one, but by throwing 10 to 20 balls and playing, communication with people becomes active and can be developed into active play. On the other hand, you can play with the concept of balls. For example, when placed on the floor, equilateral triangles and square surfaces have a large contact area with the floor and are stable, so they can be stacked up like a building block, played on a pillow or bed, and sleep on it. , A playground equipment that cultivates creativity. It is safe and can be used with peace of mind for a wide range of people, from infants to the elderly, as well as healthy people and the sick. It is also effective for rehabilitation of people with disabilities.
