DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) This disclosure will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.

(11) With reference to FIGS. 1 and 2 to 7 for a flow chart and schematic views of the statuses of different steps of a method of manufacturing a sport protective equipment in accordance with a preferred embodiment of this disclosure respectively, the manufacturing method comprises the following steps:

(12) S1: Provide a thin sheet material, a filler and a substrate, wherein the substrate is in the shape of a covered using portion. It is noteworthy that the thin sheet material 1 of this disclosure is one selected from the group consisting of thermoplastic polyurethane (TPU) and polyvinylchloride (PVC) with good elasticity, flexibility and ductility, and the thin sheet is material 1 can be shaped easily after being heated, so that this material is applicable in a vacuum shaping process and usually in a thin sheet form to prevent the shaped object from being too hard and causing a potential risk of injuries. The filling material 2 of this disclosure falls within a wide range and is selected from the group consisting of a foam, an airbag, a tubular polypropylene PP particle, a foaming polyethylene (PE) particle, and any combination of the above, and these materials are often used for absorbing the impact of a collision and has a good restoring elasticity. The actual tests conducted by the discloser of this disclosure show that the tubular polypropylene PP particle and the foaming polyethylene (PE) particle are preferred, since the relatively large particles of these material cause a low density of filling due to the good shock absorbing property of these materials. Therefore these materials are selected and used in this disclosure, not just improving the shock absorbing effect for collisions only, but also taking the features of lightweight and convenient mobility into consideration.

(13) To improve the aesthetic appearance and protection of the sports protective equipment, this disclosure further comprises the step (S1-1): Fix a surface material 4 onto a surface of the thin sheet material 1 by printing or bonding, wherein the surface material 4 is one selected from the group consisting of a dye, an elastic fabric and a plastic material, so that after the thin sheet material 1 is formed, the surface material 4 is maintained to be covered onto a surface of the thin casing 11. It is noteworthy that the surface material 4 is a decorative layer and a protective layer formed on a surface of the thin casing 11 while the thin casing 11 is being formed. Such arrangement not just improves the aesthetic appearance only, but also provides a shock absorbing effect when the thin casing is collided.

After the process of forming the thin casing 11 is completed, the filler 2 may be filled into each of the containing spaces 112 sequentially, and the level of filling may be adjusted as needed, but the level of filling is recommended to be 80% or more.

(16) S4: Install a supporting material 5 between the filler 2 and the substrate 3, wherein the supporting material 5 is a PE sheet material with a good supporting effect. To further improve the supporting effect and prevent deformations caused by an insufficient strength of the thin casing 11 of the sport protective equipment of this disclosure, the supporting material 5 is installed between the filler 2 and the substrate 3, wherein a PE sheet material is used as the supporting material 5 of this disclosure to maintain a light weight of the sports protective equipment.
