Description

BACKGROUND OF THE INVENTION1. Field of the Invention

[0001] The present invention relates to helmets and more particularly, to a helmet capable of dispersing impact force.2. Description of the Related Art

[0002] Conventional helmets typically include a rigid outer shell and a buffer layer filled within the shell. Upon an external impact, part of the force is absorbed by the rigid outer shell, part by the buffer layer, and the remaining force is borne by the user's head and cervical spine.

[0003] However, when the impact force is significant, the buffer layer alone cannot fully absorb the force, leading to direct transmission of the force to the head and resulting in injury. Thus, the structure of conventional helmets still requires improvement.SUMMARY OF THE INVENTION

[0004] It is one objective of the present invention to provide a helmet, which can effectively disperse impact force to offer sufficient protection for a wearer's head.

[0005] To attain the above objective, the helmet of the present invention comprises a helmet shell, a force-receiving member, and a force-dispersing member. The helmet shell has a rigid outer cover and a buffer layer disposed on an inner surface of the rigid outer cover. The force-receiving member is exposed on an outer surface of the rigid outer cover. The force-dispersing member is embedded within the buffer layer and connected to the force-receiving member for dispersing an impact force applied to the helmet shell or the force-receiving member.

[0006] It can be seen from the above that when the impact force is applied to the helmet shell or the force-receiving member, the impact force is not only transmitted from the rigid outer cover to the buffer layer and then to the force-dispersing member but also directly from the force-receiving member to the force-dispersing member, thereby achieving effective dispersion of the impact force and providing a cushioning and protective effect on the head.

[0007] Preferably, the force-receiving member has a front fixing portion, and the force-dispersing member has a side bracket provided with a front fixing portion fixed to the front fixing portion of the force-receiving member. In this way, the force-receiving member and the side bracket can be assembled quickly.

[0008] Preferably, the force-receiving member has two opposite force-receiving plates each have a rear fixing portion. The force-dispersing member further has a middle bracket connected between the side brackets and provided with two rear fixing portions fixed to the rear fixing portions of the force-receiving plates. In this way, the middle bracket and the force-receiving plates can be assembled quickly.

[0009] Preferably, the side brackets each have a fixing slot. The middle bracket has a plurality of side branches each provided with a side fixing portion fixed within the fixing slots of the side brackets. In this way, the middle bracket and the side branches can be assembled quickly.

[0010] Preferably, the force-dispersing member further has a front bracket provided with a fixing slot. The side brackets each have a side fixing portion fixed within the fixing slot of the front bracket. In this way, the front bracket and the side brackets can be assembled quickly.

[0011] Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Referring to FIGS. 1 and 2, a helmet 10 of the present invention comprises a helmet shell 20, a force-receiving member 30, and a force-dispersing 40.

[0027] The helmet shell 20 has a rigid outer cover 21 and a buffer layer 24. The rigid outer cover 21 is made of a rigid material such as hard plastic to serve as the first layer of protection. The buffer layer 24 is made of a shock-absorbing material such as foam material to provide shock absorption and cushioning effects. As shown in FIG. 2, the rigid outer cover 21 has an inner surface 22 and an outer surface 23, and the buffer layer 24 is fixedly disposed on the inner surface 22 of the rigid outer cover 21.

[0028] The force-receiving member 30 is made of polyamide (PA). In this embodiment, as shown in FIGS. 1 and 2, the force-receiving member 30 includes two force-receiving plates 31 arranged oppositely on the left and right sides of the outer surface 23 of the rigid outer cover 21 and exposed outward to bear an impact force. As shown in FIG. 4, the force-receiving plates 31 each have a plurality of perforations 34, which are honeycomb-shaped and pass through the inner and outer surfaces thereof. This design allows each force-receiving plate 31 to maintain structural support and breathability while achieving a distinctive visual effect. Additionally, the front end of each force-receiving plate 31 includes two spaced-apart front fixing portions 35 (as shown in FIG. 4), and the rear end of each force-receiving plate 31 includes two spaced-apart rear fixing portions 36 (as shown in FIG. 6). It is worth noting that the force-receiving member 30 is mainly disposed at the most impact-prone areas of the helmet 10. Although the force-receiving member 30 has two force-receiving plates 31 in this embodiment, in practice, the force-receiving member 30 may also be formed as a single monolithic component, as long as its size is sufficient to cover the helmet's impact-prone regions.

[0029] The force-dispersing 40 is also made of polyamide (PA). As shown in FIG. 2, the force-dispersing member 40 is embedded within the buffer layer 24 of the helmet shell 20. In this embodiment, as shown in FIGS. 4 and 6, the force-dispersing member 40 includes two side brackets 50, a middle bracket 60, and a front bracket 70.

[0030] The two side brackets 50 are disposed in a left-right opposite manner and located below the two force-receiving plates 31. As shown in FIG. 4, each side bracket 50 includes an annular portion 51, the inner edge of which is provided with multiple spaced-apart fixing slots 512. The annular portion 51 is penetrated by multiple first hollow regions 52, 53 of different sizes (the size and distribution position are not limited). The first hollow regions 52, 53 help integrate the side brackets 50 with the buffer layer 24. In addition, as shown in FIG. 4, each side bracket 50 further includes two spaced-apart front fixing portions 54 and two spaced-apart side fixing portions 55. The two front fixing portions 54 are connected to the top surface of the front edge of the annular portion 51, and the two side fixing portions 55 protrude forward from the front edge of the annular portion 51. During assembly, as shown in FIGS. 7 and 8, the two front fixing portions 54 of each side bracket 50 are fixed to the two front fixing portions 35 of the force-receiving plate 31 by snap-fit, ultrasonic welding, or adhesive bonding, thus enabling quick assembly. However, the side brackets 50 and the force-receiving plates 31 are not limited to be assembled by means of these methods, but can also be made monolithically, which can also achieve the effect of force transmission.

[0031] The middle bracket 60 is located between the two side brackets 50 and is positioned at the center of the helmet 10. As shown in FIGS. 4 and 6, the middle bracket 60 includes a main stem 61, multiple side branches 62, and a rear branch 63. The side branches 62 are arranged in pairs on two opposite sides of the main stem 61 and are spaced along the extension direction of the main stem 61. One end of each side branch 62 is monolithically connected to the main stem 61, and the other end of each side branch 62 includes a side fixing portion 622. Further, the side branches 62 extend downwardly in an arched manner from the main stem 61 toward the side brackets 50. As shown in FIGS. 9 and 10, the side fixing portions 622 of the side branches 62 are fixed to the fixing slots 512 of the side brackets 50 by snap-fit, ultrasonic welding, or adhesive bonding, allowing for rapid assembly of the middle bracket 60 and the side brackets 50. After assembly, a second hollow region 65 is formed between the main stem 61, two adjacent side branches 62, and the side bracket 50 (see FIG. 3). This second hollow region 65 integrates the middle bracket 60, the side brackets 50, and the buffer layer 24. Additionally, as shown in FIG. 6, the rear branch 63 is monolithically connected to the rear end of the main stem 61 and includes a third hollow region 632, which connects the middle bracket 60 and the buffer layer 24. The middle bracket 60 also has four rear fixing portions 64 arranged in two pairs on the left and right sides of the rear branch 63. These rear fixing portions 64 of the middle bracket 60 are fixed to the corresponding rear fixing portions 36 of the force-receiving plates 31 by snap-fit, ultrasonic welding, or adhesive bonding (as shown in FIGS. 11 and 12), enabling fast assembly of the middle bracket 60 and the two force-receiving plates 31.

[0032] As shown in FIG. 4, the top edge of the front bracket 70 has four spaced fixing slots 72. These fixing slots 72 are fixed to the side fixing portions 55 of the side brackets 50 by snap-fit, ultrasonic welding, or adhesive bonding (as shown in FIGS. 13 and 14), allowing for rapid assembly of the front bracket 70 with the two side brackets 50. After assembly, the front bracket 70 extends forward and downward from the side brackets 50, so that the front bracket 70 is positioned to correspond with the wearer's forehead. Additionally, the front bracket 70 also includes multiple fourth hollow regions 74, 75 of varying sizes and positions, which integrate the front bracket 70 with the buffer layer 24.

[0033] From the above, it can be seen that when the helmet shell 20 or the force-receiving member 30 is subjected to an external impact, the force is transmitted from the rigid outer cover 21 to the buffer layer 24, and from the buffer layer 24 to the two side brackets 50, the middle bracket 60, and the front bracket 70 of the force-dispersing member 40. Additionally, the external force is also transmitted from the force-receiving member 30 to these components of the force-dispersing member 40. In this way, the impact force is effectively dispersed to provide the wearer's head with reliable cushioning and protection, thus achieving the objectives of the present invention.

[0034] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.

[0026] Referring to FIGS. 1 and 2, a helmet 10 of the present invention comprises a helmet shell 20, a force-receiving member 30, and a force-dispersing 40.

[0027] The helmet shell 20 has a rigid outer cover 21 and a buffer layer 24. The rigid outer cover 21 is made of a rigid material such as hard plastic to serve as the first layer of protection. The buffer layer 24 is made of a shock-absorbing material such as foam material to provide shock absorption and cushioning effects. As shown in FIG. 2, the rigid outer cover 21 has an inner surface 22 and an outer surface 23, and the buffer layer 24 is fixedly disposed on the inner surface 22 of the rigid outer cover 21.

[0028] The force-receiving member 30 is made of polyamide (PA). In this embodiment, as shown in FIGS. 1 and 2, the force-receiving member 30 includes two force-receiving plates 31 arranged oppositely on the left and right sides of the outer surface 23 of the rigid outer cover 21 and exposed outward to bear an impact force. As shown in FIG. 4, the force-receiving plates 31 each have a plurality of perforations 34, which are honeycomb-shaped and pass through the inner and outer surfaces thereof. This design allows each force-receiving plate 31 to maintain structural support and breathability while achieving a distinctive visual effect. Additionally, the front end of each force-receiving plate 31 includes two spaced-apart front fixing portions 35 (as shown in FIG. 4), and the rear end of each force-receiving plate 31 includes two spaced-apart rear fixing portions 36 (as shown in FIG. 6). It is worth noting that the force-receiving member 30 is mainly disposed at the most impact-prone areas of the helmet 10. Although the force-receiving member 30 has two force-receiving plates 31 in this embodiment, in practice, the force-receiving member 30 may also be formed as a single monolithic component, as long as its size is sufficient to cover the helmet's impact-prone regions.

[0029] The force-dispersing 40 is also made of polyamide (PA). As shown in FIG. 2, the force-dispersing member 40 is embedded within the buffer layer 24 of the helmet shell 20. In this embodiment, as shown in FIGS. 4 and 6, the force-dispersing member 40 includes two side brackets 50, a middle bracket 60, and a front bracket 70.

[0030] The two side brackets 50 are disposed in a left-right opposite manner and located below the two force-receiving plates 31. As shown in FIG. 4, each side bracket 50 includes an annular portion 51, the inner edge of which is provided with multiple spaced-apart fixing slots 512. The annular portion 51 is penetrated by multiple first hollow regions 52, 53 of different sizes (the size and distribution position are not limited). The first hollow regions 52, 53 help integrate the side brackets 50 with the buffer layer 24. In addition, as shown in FIG. 4, each side bracket 50 further includes two spaced-apart front fixing portions 54 and two spaced-apart side fixing portions 55. The two front fixing portions 54 are connected to the top surface of the front edge of the annular portion 51, and the two side fixing portions 55 protrude forward from the front edge of the annular portion 51. During assembly, as shown in FIGS. 7 and 8, the two front fixing portions 54 of each side bracket 50 are fixed to the two front fixing portions 35 of the force-receiving plate 31 by snap-fit, ultrasonic welding, or adhesive bonding, thus enabling quick assembly. However, the side brackets 50 and the force-receiving plates 31 are not limited to be assembled by means of these methods, but can also be made monolithically, which can also achieve the effect of force transmission.

[0031] The middle bracket 60 is located between the two side brackets 50 and is positioned at the center of the helmet 10. As shown in FIGS. 4 and 6, the middle bracket 60 includes a main stem 61, multiple side branches 62, and a rear branch 63. The side branches 62 are arranged in pairs on two opposite sides of the main stem 61 and are spaced along the extension direction of the main stem 61. One end of each side branch 62 is monolithically connected to the main stem 61, and the other end of each side branch 62 includes a side fixing portion 622. Further, the side branches 62 extend downwardly in an arched manner from the main stem 61 toward the side brackets 50. As shown in FIGS. 9 and 10, the side fixing portions 622 of the side branches 62 are fixed to the fixing slots 512 of the side brackets 50 by snap-fit, ultrasonic welding, or adhesive bonding, allowing for rapid assembly of the middle bracket 60 and the side brackets 50. After assembly, a second hollow region 65 is formed between the main stem 61, two adjacent side branches 62, and the side bracket 50 (see FIG. 3). This second hollow region 65 integrates the middle bracket 60, the side brackets 50, and the buffer layer 24. Additionally, as shown in FIG. 6, the rear branch 63 is monolithically connected to the rear end of the main stem 61 and includes a third hollow region 632, which connects the middle bracket 60 and the buffer layer 24. The middle bracket 60 also has four rear fixing portions 64 arranged in two pairs on the left and right sides of the rear branch 63. These rear fixing portions 64 of the middle bracket 60 are fixed to the corresponding rear fixing portions 36 of the force-receiving plates 31 by snap-fit, ultrasonic welding, or adhesive bonding (as shown in FIGS. 11 and 12), enabling fast assembly of the middle bracket 60 and the two force-receiving plates 31.

[0032] As shown in FIG. 4, the top edge of the front bracket 70 has four spaced fixing slots 72. These fixing slots 72 are fixed to the side fixing portions 55 of the side brackets 50 by snap-fit, ultrasonic welding, or adhesive bonding (as shown in FIGS. 13 and 14), allowing for rapid assembly of the front bracket 70 with the two side brackets 50. After assembly, the front bracket 70 extends forward and downward from the side brackets 50, so that the front bracket 70 is positioned to correspond with the wearer's forehead. Additionally, the front bracket 70 also includes multiple fourth hollow regions 74, 75 of varying sizes and positions, which integrate the front bracket 70 with the buffer layer 24.

[0033] From the above, it can be seen that when the helmet shell 20 or the force-receiving member 30 is subjected to an external impact, the force is transmitted from the rigid outer cover 21 to the buffer layer 24, and from the buffer layer 24 to the two side brackets 50, the middle bracket 60, and the front bracket 70 of the force-dispersing member 40. Additionally, the external force is also transmitted from the force-receiving member 30 to these components of the force-dispersing member 40. In this way, the impact force is effectively dispersed to provide the wearer's head with reliable cushioning and protection, thus achieving the objectives of the present invention.

[0034] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
