The present invention relates generally to a universal anti-collision structure of safety helmet, and more particularly to a universal anti-collision structure of safety helmet, which employs (cushion foam) filling body connected with a shell body and an elastic carrier body. The elastic carrier body has multiple walls as a skeleton structure. The walls define multiple well-shaped structure sections with a geometrical configuration. The filling body is bonded with the shell body and the elastic carrier body to together form a complex integrated assembly.
A conventional safety helmet structure includes a plastic shell body and an anti-impact filling body formed of foam material by heating. The plastic shell body tightly encloses and adheres to the foam filling body to form the safety helmet structure.
In the structural form of such kind of safety helmet, the outer plastic shell serves to resist against the thrust-type impact of an alien object. Also, when bearing the external impact, the foam filling material serves to cushion the impact force and distributively transmit the impact force so as to achieve a protection effect for the wearer's head.
It is known that a thin layer of lining is generally disposed in an innermost position of the conventional helmet as a cushion between the helmet and a wearer's head. The lining is generally made of a fabric. With respect to the structural property and application of the thin layer of lining, it is troublesome to additionally dispose the lining in the safety helmet because the number of the assembling steps is increased. Moreover, the material property of the thin layer of lining leads to that the comfortableness of a helmet wearer can be hardly effectively enhanced and the mugginess of the wearer in long-term wear cannot be reduced.
As well known by those who are skilled in this field, due to the limitation of the structural form and property of the thin layer of lining, in order to more fully enclose the wearer's head and enhance the snugness in wear of the helmet, in practice, it is necessary to manufacture many different specifications of helmet products in accordance with the sizes of the heads of the wearers. This obviously leads to increase of the manufacturing cost. Such condition is not what we expect.
Still with respect to the structural form and application of the thin layer of lining of the safety helmet, even though various sizes of conventional helmet products are provided for different wearers, the helmet and the thin layer of lining still cannot truly fully enclose and snugly attach to the wearer's head in accordance with the head configurations or the arched faces of the wearer's head.
That is, even though various sizes or specifications of conventional safety helmets are provided for different wearers, the helmets still fail to completely conform to the three-dimensional head configurations or the arched faces of the wearer's head. As a result, the helmet can hardly fully enclose the wearer's head and the snugness in wear of the helmet is deteriorated. Therefore, when an external impact force is applied to the helmet, the protection and security effect provided by the helmet for the wearer's head will be affected.
To speak representatively, the conventional safety helmet has some shortcomings in design of the structure and the manufacturing process. Also, in practice, some problems existing in the assembling structures of the outer shell body or plastic shell, the inner structure body and the thin layer of lining of the conventional safety helmet. To overcome the above shortcomings, it is necessary to redesign the assembling structures and connection relationship between the shell body or plastic shell and the foam material layer or the thin layer of lining of the conventional safety helmet so as to simplify the manufacturing process and change the safety helmet into a different one. The redesigned safety helmet has more ideal protection ability and better comfortableness in wear. Accordingly, the distribution and transmission pattern of the external impact force are changed to improve the shortcomings of the conventional safety helmet.
It is found that the conventional safety helmet structure has some shortcomings that it is troublesome to additionally dispose the lining in the safety helmet because the number of the assembling steps is increased and the comfortableness of the helmet wearer in wear can be hardly enhanced. In addition, the texture of the conventional helmet fails to elastically conform to different three-dimensional head configurations or arched faces and sizes of the heads of the wearers. As a result, the helmet can hardly fully enclose the wearer's head and the snugness in wear of the helmet cannot be enhanced. Therefore, when various external impact forces (normal or lateral) are applied to the helmet, the internal structure body of the helmet can hardly effectively distribute and transmit the impact forces to every part of the entire helmet. All these shortcomings need to be improved. Moreover, the safety helmet must meet the trend to simplify manufacturing process and design lightweight and thin safety helmet structure. All these issues are not suggested or disclosed in the above reference patents.
It is therefore a primary object of the present invention to provide a universal anti-collision structure of safety helmet including a shell body, a filling body and an elastic carrier body enclosed in and assembled with the shell body. The elastic carrier body has multiple walls as a skeleton structure. The walls define multiple well-shaped structure sections with a geometrical configuration. The peripheral section of each well-shaped structure section is formed with wing sections (protruding toward the center of the well-shaped structure section). Accordingly, the well-shaped structure section is defined with a first section, a second section and a subsidiary section connected between the first and second sections. The filling body is bonded with the shell body and the elastic carrier body to together form an integrated assembly. The structural strength of the entire assembly is enhanced and the first section (or the wall) extends in a direction to (the interior) of the filling body. The elastic carrier body can be flexibly deformed in accordance with different head configurations so as to fully enclose the head, cushion, absorb and transmit the external impact force as well as enhance the comfortableness and snugness in wear.
In the above universal anti-collision structure of safety helmet, the material of the filling body partially at least goes into the first section and/or the subsidiary section of the elastic carrier body, whereby the filling body is connected or bonded with the elastic carrier body to form an integrated structure. (The term “bonded” means that the material of the filling body is passed through or filled in and connected with the first section and the subsidiary section or the wing sections and the wall). This improves the troublesome manufacturing process of the conventional safety helmet that it is necessary to additionally assemble a thin layer of lining. In addition, the filling body is connected with the elastic carrier body to form such a texture that the elastic carrier body and the filling body provide an inter-supporting system or effect. When the shell body and the filling body bear external impact force to achieve the cushioning and shock absorption effect, the elastic carrier body also serves to distributively transmit the impact force.
In practice, the filling body is connected with the first sections and/or the subsidiary section of the elastic carrier body to form such a structure that the lower wall of the second section becomes an elastic section. The elastic section can be flexibly deformed to different extents in accordance with different sizes of the wearer's head, the three-dimensional head configurations or the arched faces of the wearer's head. Therefore, it is easy for the elastic section to fully elastically contact the wearer's head to enhance the comfortableness of the wearer's head and make the wearer's head more fully enclosed and enhance the snugness of the attachment in wear of the helmet. This improves the structural shortcomings of the conventional helmet and/or the thin layer of lining.
Especially, when the lower wall of the second section is flexibly deformed to different extents to fully elastically contact the wearer's head, an air chamber structure is set up between the well-shaped structure section (or the second section) and the wearer's head as a flexible sucker. Accordingly, the elastic carrier body is easy to fully attach to the wearer's head in accordance with the different head configurations or the arched faces of the wearer's head to provide more ideal protection and security effect than the conventional helmet. Moreover, when responding to the external impact force, the air chamber serves to cushion and absorb the external impact force.
In the above universal anti-collision structure of safety helmet, at least one elastic structure body and/or a subsidiary shell body is disposed between the inner face of the shell body and the filling body. The elastic structure body is defined with an upper section and a lower section. The upper and lower sections of the elastic structure body are respectively formed with multiple assembling sections. The shell body and/or the subsidiary shell body are formed with multiple pivotal connection sections correspondingly assembled with the assembling sections. The filling body is bonded with the elastic structure body and the shell body and/or the subsidiary shell body to form an integrated form. The structural strength of the entire assembly is enhanced to achieve a multilayered structure and universal cushioning and external impact force (or normal impact force and rotational torque) absorption and transmission effects.
In the above universal anti-collision structure of safety helmet, the well-shaped structure section of the elastic carrier body is formed with an elastic column extending toward the filling body (or the shell body). The elastic column includes a connection end connected with the upper wall and a free end extending toward the filling body. A connection face is formed between the connection end and the upper wall of the well-shaped structure section. The free end has a contact face. The width of the cross section of the elastic column is larger than the thickness (or cross-sectional width) of the wall or the upper wall. When responding to a greater external impact force, the elastic column serves to form a breakage point on the connection face.
The present invention can be best understood through the following description and accompanying drawings, wherein:
Please refer to
The upper section, upper side, lower section, lower side or bottom section mentioned hereinafter are referred to with the direction of the drawings as the reference direction. In addition, the part directed to the helmet wearer is defined as inner face or inner side, while the part directed away from the helmet wearer is defined as outer face or outer side.
In a preferred embodiment, the shell body 10 can be selectively made of plastic material. The shell body 10 has an inner face 11 directed to the helmet wearer and an outer face 12 directed away from the helmet wearer. The inner face 11 of the shell body 10 contacts or connects with the filling body 30. In addition, a protection layer 60 is disposed on the outer face 12 of the shell body 10. The protection layer 60 is selectively made of fiber glass, fiber carbon or the like material. The protection layer 60 serves to enhance the structural strength of the shell body 10.
As shown in the drawings, the elastic carrier body 40 is disposed in an innermost position of the safety helmet or the assembly 100 as an innermost layer (distal from the shell body 10). The elastic carrier body 40 is connected with a lower section 31 of the filling body 30. The elastic carrier body 40 is selectively made of flexible or elastic material (such as rubber or the like material). The elastic carrier body 40 has the form of a cellular texture. The lower section 31 of the filling body 30 is positioned in a position distal from the inner face 11 of the shell body.
The drawings show that the elastic carrier body 40 includes multiple walls 49 as a skeleton structure. The walls 49 define multiple well-shaped structure sections 45. The well-shaped structure sections 45 have (a cross section with) a geometrical configuration (such as a hexagonal configuration of a cellular structure). In addition, each wall 49 has wing sections 46 protruding toward two sides or a peripheral section (or a peripheral section of the well-shaped structure section 45). Accordingly, the well-shaped structure section 45 is defined with a first section 41, a second section 42 and a subsidiary section 43 between the first and second sections 41, 42. The cross section of the first section 41 or the second section 42 is larger than the cross section of the subsidiary section 43. Accordingly, the wall 49 and the wing sections 46 positioned on two sides of the wall 49 (or the skeleton structure) together form a structure with a “+++”-shaped cross section. Therefore, the elastic carrier body 40 can fully contact or enclose a wearer's head H as shown in
In this embodiment, the elastic carrier body 40 includes a frame body 44 formed on the bottom section of the elastic carrier body 40. The frame body 44 extends toward an outer side of the elastic carrier body 40 (in a direction to the shell body 10) to form a structure with a U-shaped cross section. The frame body 44 serves to enclose and connect with the shell body 10 and the foam filling body 30.
The wall 49 is defined with an upper wall 47 and a lower wall 48 corresponding to the positions of the first and second sections 41, 42. By means of a mold or a molding module, the filling body 30 is bonded with the shell body 10 and the elastic carrier body 40 to form an integrated structure of the safety helmet assembly 100.
To speak more specifically, the (cushioning foam) material of the filling body 30 partially at least goes into the first section 41 and/or the subsidiary section 43 of the elastic carrier body 40, whereby the filling body 30 is connected or bonded with the elastic carrier body 40 to form an integrated structure. (The term “bonded” means that the material of the filling body 30 is passed through or filled in and connected with the first section 41 and the subsidiary section 43 or the wing sections 46 and the wall 49). Therefore, at least the first section 41 (or the upper wall 47) extends to (the interior of) the filling body 30. This improves the troublesome manufacturing process of the conventional safety helmet that it is necessary to additionally assemble a thin layer of lining.
Preferably, the material of the filling body 30 is partially filled up in the entire first section 41 and the entire subsidiary section 43 to connect with the upper wall 47 and the wing sections 46. Moreover, the elastic carrier body 40 (is assembled with the filling body 30) to form a structural form and achieve such a material property that when the elastic carrier body 40 responds to an external impact force (such as normal force or shear force), the elastic carrier body 40 is elastically deformed and/or rotationally deformed so as to cushion and absorb the external impact force and speed.
It should be noted that the filling body 30 is connected with the elastic carrier body 40 to form such a texture that the elastic carrier body 40 and the filling body 30 provide an inter-supporting system or effect. When the shell body 10 and the filling body 30 bear external impact force to achieve the cushioning and shock absorption effect, the elastic carrier body 40 also serves to distributively transmit the impact force. Accordingly, the structural strength of the entire assembly 100 is enhanced to universally or multidirectionally cushion and absorb the rotational torque and transmit the external impact force.
It should be noted that the filling body 30 is connected with the first sections 41 and/or the subsidiary section 43 to form such a structure that the lower wall 48 of the second section 42 becomes an elastic section. The elastic section can be flexibly deformed to different extents in accordance with different sizes of the wearer's head, three-dimensional head configurations or the arched faces of the wearer's head (as shown by the solid lines of
Especially, when the lower wall 48 of the second section 42 is flexibly deformed to different extents to fully elastically contact the wearer's head H, an air chamber structure is set up between the well-shaped structure section 45 (or the second section 42) and the wearer's head H. The air chamber structure provides a sucking effect as a flexible sucker. Accordingly, the elastic carrier body 40 is easy to fully attach to the wearer's head H in accordance with the different head configurations or the arched faces of the wearer's head H to provide more ideal protection and security effect than the conventional helmet. Moreover, when responding to the external impact force, the air chamber serves to cushion and absorb the external impact force.

The term “floatable” means when the parts of the assembly 100 respond to the external action force, the parts of the assembly 100 can relatively move and/or rotate within the assembly 100. For example, when the elastic structure body 20 responds to the external action force, the elastic structure body 20 can be elastically squeezed and deformed to relatively move and/or rotate between the main shell body 10 and the subsidiary shell body 50.
Preferably, the shell body 10, the filling body 30 (and/or the elastic structure body 20 and the subsidiary shell body 50) are formed with vent structures (not shown). Alternatively, there are gaps between the foam materials of the filling body 30. In this case, the vent structures or the gaps can cooperate with the well-shaped structure sections 45 of the elastic carrier body 40 to help in enhancing the air convection of the assembly 100. This can reduce the mugginess of the user in long-term wear.
In this embodiment, the elastic structure body 20 is selectively made of flexible or elastic material such as EPS, EVA, rubber or the like material. Therefore, the elasticity ratio (or deformation amount) of the elastic structure body 20 is larger than the elasticity ratio (or deformation amount) of the filling body 30.
Accordingly, the deformation and cushioning shock absorption effect of the elastic structure body 20 is enhanced.
As shown in the drawings, the elastic structure body 20 is defined with or has an upper section 21 and a lower section 22. The upper and lower sections 21, 22 of the elastic structure body 20 are respectively formed with multiple assembling sections 23. The assembling sections 23 of the elastic structure body 20 are formed with grooves 24. The grooves 24 define the assembling sections 23 to have a geometrical configuration (such as hexagonal configuration). Accordingly, the assembling sections 23 are adjacent to each other to form a cellular structure.
In this embodiment, the subsidiary shell body 50 is selectively made of plastic material. The subsidiary shell body 50 has an inner face 51 directed to the wearer and an outer face 52 directed away from the wearer. By means of a mold or a molding module, the filling body 30 is bonded with the inner face 51 of the subsidiary shell body 50. The inner face 11 of the shell body and the outer face 52 of the subsidiary shell body respectively contact or connect with the upper and lower sections 21, 22 of the elastic structure body 20.
As shown in the drawings, the inner face 11 of the shell body 10 and the outer face 52 of the subsidiary shell body 50 are respectively formed with (elastic) pivotal connection sections 13, 53. The pivotal connection sections 13, 53 of the shell body 10 and the subsidiary shell body 50 respectively have protruding walls 14, 54. The walls 14, 54 define the pivotal connection sections 13 (or 53) to have a geometrical configuration (such as hexagonal configuration). Accordingly, the pivotal connection sections 13 (or 53) are adjacent to each other to form a cellular structure. The pivotal connection sections 13, 53 are correspondingly assembled with or mortised with the assembling sections 23 of the elastic structure body 20.
In a preferred embodiment, the elastic structure body 20 has holes 25 formed on the assembling sections 23 and passing through the elastic structure body 20. A fluid can be filled in the holes 25 to adjust or change the elasticity ratio of the elastic structure body 20.
