Description

  The present invention relates to a flying disk suitable for infant growth support and function recovery for the elderly.

  In recent years, it has been reported that children's physical strength and athletic ability are on a decline. The reasons for this include a decrease in time spent playing outside and playing sports, and a decrease in opportunities for walking due to the development of transportation means. In early childhood, basic movements such as walking, jumping, throwing, and grabbing are remarkably developed, and motor ability is greatly improved. Improving athletic ability in early childhood will also improve youth's athletic ability. In addition, even for elderly people, there is a problem that mental and physical functions and living functions deteriorate due to lack of exercise. If deterioration of mental and physical functions and living functions accompanying aging progresses, care will be required. In order to avoid this, it is necessary to improve health and increase independence by increasing physical activity.

  One of the exercises for solving the decline in exercise ability and lack of exercise is the flying disk. This flying disc is known by the name of Frisbee (registered trademark), and it is played by throwing it, and there are competitions for throwing techniques and distances.

  As shown in Patent Document 1, an outer rim and a circular airfoil provided inside are provided, and as shown in Patent Document 2, a disk-shaped hard plastic is proposed.

However, even if the conventional flying disc is suitable for exercise, the conventional product has various problems such as hardness, too long flight distance, difficult to determine direction, difficult to throw towards the opponent, and pain when hitting a person. is there. Also, the exercise of throwing a flying disc was not suitable for infants and the elderly. With such products, it is difficult to keep exercising and continuous exercise cannot be achieved, so it is not possible to contribute to the growth assistance of infants or the functional recovery of the elderly.
In view of the above, the present invention promotes continuous exercise of infants, the elderly, etc. by providing a flying disk that has an appropriate hardness and flight distance and is easy to determine the direction, assists in growth, recovers functions, etc. The purpose is to contribute.

The present invention has features such as moderate hardness and flight distance, easy orientation, etc., and a tertiary structure including a spring structure composed of continuous filaments that are randomly entangled in a loop shape and partially heat-welded. It is a flying disk which is an original network structure and has a three-dimensional network structure with a bulk density of 0.03 to 0.4 g / cm ³ and a continuous filament diameter of 0.1 to 4 mm. In addition, the present invention can use not only the arm but also the head by providing a game characteristic by obtaining a privilege such as ring throwing by making a hole in the spring structure part and making it a donut shape, and more continuous power can be used. By going up, it can be said that it is more suitable for growth assistance and functional recovery.

  The shape of the flying disk is preferably circular, but may be other shapes such as oval. As the raw material, a virgin thermoplastic resin or a recycled raw material can be used, and a pigment, an antibacterial agent, or the like may be mixed.

  There are three types of flying disk structures in order to prevent them from unraveling the ends of the continuous filaments. 1. 1. Fusing the ends. Cover the entire surface or a part of the three-dimensional network structure (for example, the periphery of the side surface) 3. Coating the three-dimensional network structure with resin or the like.

  According to the present invention, it is possible to promote a throwing exercise indispensable for the development / development of general people, infants, elderly people and the like, and improvement of exercise ability. In the elderly, continuing moderate exercise of stroking the flying disk can prevent a decrease in bone density, reduce the possibility of injury, and is considered to be useful for functional recovery of the elderly. There is less impact when the flying disk hits a person, and safety is increased. You can also play at short distances. In addition, by making a hole in the spring structure and making it into a donut shape, it is possible to promote brain development and functional recovery by calculating the score using usage like ring throwing.

1 is a perspective view of a flying disc 1. FIG. 1 is a cross-sectional view of a flying disc 1. FIG. FIG. 6 is a perspective view of a modified example of the flying disk 1.

  Hereinafter, a flying disk 1 according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the flying disk 1 is a three-dimensional network structure using a thermoplastic resin or a thermoplastic elastic resin as a raw material or a main raw material. Comprising a three-dimensional network structure 2 having a spring structure composed of a plurality of solid continuous filaments that are thermally heat-bonded, and a cover 3 that covers the outer periphery of the side surface of the three-dimensional network structure 2 It is. The cover 3 is preferably made of a flexible material such as cloth or resin. It is good also as a hollow continuous filament instead of a solid continuous filament. In the case of hollow continuous filaments, the ends of the continuous filaments may be open, or the ends are closed, and air with a pressure exceeding atmospheric pressure is enclosed in the hollow part of the hollow continuous filaments. Also good. Instead of air, a liquid (for example, a gel or the like) may be enclosed in the hollow portion.

  The raw material or the main raw material which is a thermoplastic resin uses a flake shape such as a PET bottle or a chip shape. A PET bottle is crushed as it is and melted to form a flake. It can also be applied to thermoplastic resins other than recycled materials. For example, as thermoplastic resins, polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamides such as nylon 66, polyvinyl chloride, polystyrene, copolymers and elastomers based on the above resins, and blends of the above resins Etc. A polyethylene resin mixed with vinyl acetate resin and rubber is preferable. If the raw material is thermoplastic urethane, elasticity can be maintained with low resilience.

The three-dimensional network structure 2 is set to a bulk density of 0.03 to 0.4 g / cm ³ and a wire diameter (diameter) of a continuous filament of 0.1 to 4 mm. The wire diameter (diameter) of the continuous filament is particularly preferably 0.5 to 1 mm. The radius of the three-dimensional network structure 2 is preferably 8 cm to 20 cm, particularly preferably 8 cm to 14 cm, and the thickness is preferably 10 mm to 150 mm, particularly preferably 15 mm to 40 mm.
