The technical field relates to the manufacture of sports protective equipments, and more particularly to a method of manufacturing a sport protective equipment and a sport protective equipment manufactured by the method, wherein a casing is manufactured and integrally formed in a vacuum forming process and provided for containing a shock absorbing material to substitute the conventional sewn containing bag or casing that takes much time and efforts.
In modern sports such as baseball and American football games, equipments and players' body usually collide with one another during the game, and the players may be injured by the impacts of the collision easily. Therefore, sports protective equipments are used according to different requirements. For example, hockey goalkeepers wear gloves and protective gears, and baseball catchers wear protective equipments, etc. These sports protective equipments not just protect the player's body during the vigorous physical activity only, but also take flexibility and mobility into consideration for the game to improve the players' safety and the level of excitement of the game.
To absorb the impact of various type of collisions, these sports protective equipments are made of shock absorbing materials such as silicone, foam, sponge, etc and also require a casing for fixing the shock absorbing materials effectively, and a soft fabric that can be worn to cover a part of the wearer's body. However, the design of the sports protective equipments of the sort must be easy and convenient to be taken off. More importantly, these sports protective equipments do not affect the mobility and flexibility of the wearer's activities. Therefore, it is exceptionally important to design a sport protective equipment with a good shock absorbing effect without affecting the mobility and flexibility of the wearers' activities.
In general, the shock absorbing material is elastic and not easy-to-shape, so that the sport protective equipment may be deformed by collisions easily, and most sports protective equipments generally come with a casing made of a hard and light material or a containing bag or box formed by sewing fabrics to cover and fix the shock absorbing material.
However, the hard casing may affect the mobility and flexibility of the wearer's activity, so that the volume of the casing is preferably not too large, and the design preferably has a plurality of casings stitched or bonded to the fabric. As a result, the thickness of the stitching or sewing portion is increased, or the tension of the sewing thread causes an increase of thickness and hardness and affects the activity of sports adversely. In addition, the manufacturing procedure requires the step of fixing the casings onto a substrate one by one, and such complicated manufacturing procedure takes much time and effort, not just causing a low efficiency only, but also increasing the manufacturing cost and the assembling cost. Although the shape of the containing bags or boxes made of fabric and manufactured manually by stitching may be changed as needed, yet the manufacturing efficiency of the manual stitching is low, and the quality of the finished goods cannot be controlled easily. In addition, the fabrics are folded and sewed repeatedly, so that the thickness is increased, the hardness is increased, and the flexibility of the wearer's activity is affected adversely.
In view of the aforementioned drawbacks, this disclosure provides a method of manufacturing a sport protective equipment and a sport protective equipment manufactured by the method to achieve the effects of improving the manufacturing efficiency and the quality of the finished goods and reducing the manufacturing cost. The sport protective equipment comprises a thin casing made of a thin sheet material in a vacuum shaping process and having a plurality of containing spaces disposed apart from each other and formed on a surface of the casing for filling a filling material, and the casing may be combined with a substrate directly to save the manufacturing time of bonding a large quantity of casings, and the containing spaces of the thin casing manufactured by the vacuum shaping process are fixed and arranged apart from one another without requiring any other tool, so as to improve the manufacturing efficiency and the quality of the finished goods significantly.
In view of the problems of the prior art, it is a primary objective of this disclosure to provide a method of manufacturing a sport protective equipment to achieve the effects of improving the manufacturing efficiency and reducing the production cost.
To achieve the aforementioned and other objectives, this disclosure provides a method of manufacturing a sports protective equipment, comprising the steps of: providing a thin sheet material, a filler and a substrate, wherein the substrate is in the shape of a covered using portion; manufacturing a thin casing by the thin sheet material in a vacuum forming process, and forming a plurality of protrusions arranged apart from one another on a surface of the thin casing, such that a containing space is formed on an inner side of each protrusion, and the thin casing is manufactured in a shape corresponsive to the substrate; filling the filler into each of the containing spaces; and sealing the bottom of the thin casing by the substrate, so that the filler in each of the containing spaces will not fall out. This method skips the steps of a conventional manufacturing process including the repeated shaping, positioning and bonding steps of manufacturing a casing, so as to improve the manufacturing efficiency and lower the manufacturing cost effectively. Obviously, such method is very helpful to the future development of sports protective equipments.
To improve the aesthetic appearance and protection of the sports protective equipment, the manufacturing method of this disclosure further comprises the step of bonding a surface material, wherein a surface material is bonded onto a surface of the thin sheet material before the step of “providing a thin sheet material, a filler and a substrate, wherein the substrate is manufactured in the shape of a covered using portion” takes place, and the surface material is one selected from the group consisting of an elastically contractible fabric and a plastic material, so that the surface material is covered onto a surface of the thin casing. It is noteworthy that the surface material can be formed in the shape of the thin casing while the thin sheet material is being formed in the vacuum forming process, and the surface material is provided for absorbing the impact when the thin casing is collided, and the surface material with different patterns and colors can improve the aesthetic appearance of the sports protective equipment.
In a preferred embodiment, the thin sheet material is one selected from the group consisting of thermoplastic polyurethane (TPU) and polyvinylchloride (PVC), and the filling material is one 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.
To improve the supporting effect and preventing insufficient strength of the hard casing, the method of this disclosure further comprises the step of installing a supporting material, wherein a supporting material is installed between the filler and the substrate after the step of “filling the filler into each of the containing spaces” is completed, and the supporting material is a sheet material made of polyethylene (PE). Such arrangement provides the required supporting effect to users who wear the sport protective equipment without increasing too much weight or affecting the flexibility of the wearer's activity.
A secondary objective of this disclosure is to provide a sport protective equipment manufactured by the aforementioned method, so as to achieve the effects of improving the manufacturing efficiency and reducing the production cost.
To achieve the aforementioned and other objectives, this disclosure further provides a sport protective equipment comprising: the plurality of protrusions, arranged apart from one another and protruded on a surface of the thin casing, after the thin sheet material is formed by a vacuum forming process, such that a containing space is formed on an inner side of each of the protrusions; the filler, installed in each of the containing spaces; and the substrate, manufactured in the shape corresponsive to a covered using portion, and the thin casing being in the shape corresponsive to the shape of the substrate, and the substrate being provided for sealing the thin casing, so that the filler in each of the containing spaces will not fall out.

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.
With reference to
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.
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.
S2: Manufacture a thin casing 11 by the thin sheet material 1 in a vacuum forming process, and form a plurality of protrusions 111 arranged apart from one another on a surface of the thin casing 11, such that a containing space 112 is formed on an inner side of each protrusion 111, and the thin casing 11 is manufactured in the shape of the substrate 3. In a vacuum forming process, the thin sheet material 1 is preheated and softened and then clamped into a mold to form the thin casing 11 by a vacuum shaping process, such that the protrusions 111 arranged apart with each other are formed on a surface corresponsive to the mold, and the protrusion 111 contains a containing space 112 therein. After the shaping process is completed, the thin casing 11 is cut into a shape corresponsive to the substrate 3 to facilitate carrying out the processes that follow. It is noteworthy that the thin sheet material has the physical properties including elasticity, flexibility and ductility, so that the thin sheet material applied in the vacuum forming process will not break or crack easily.
S3: Fill the filler 2 into each of the containing spaces 112. 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.
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.
S5: Seal the bottom of the thin casing 11 by the substrate 3, so that the filler 2 in each of the containing spaces 112 will not fall out. The substrate 3 and the thin casing 11 are sealed by high frequency or thermal fusion, so that the filler 2 and the supporting material 5 in the containing space 112 will not fall out. After being sewn with other fabrics, a sport protective equipment is manufactured.
