Description

Field of the invention

[0001] The invention relates to the field of protective armor, in particular a Taekwondo chest armor for children. State of the art

[0002] In children's Taekwondo training and competitions, the chest and back are the most commonly affected body parts. The kicking motion in Taekwondo generates a strong, instantaneous impact force and a short contact time. A child's chest is not yet fully developed. While the ribs have high elasticity, their impact resistance is low. Inadequate protection can lead to sternal contusion, visceral shock, and other injuries. Therefore, wearing a chest protector to protect the chest is required.

[0003] Currently, children's chest protectors on the market are made of foam and rubber materials. While foam has a certain cushioning ability, its cushioning effect is limited. Under large impact forces, it is difficult to fully protect the child's chest from injury. Furthermore, after prolonged use, the foam is easily subject to aging, deformation, and other problems, leading to a reduction in cushioning properties. The rubber material has a hard texture and is uncomfortable to wear, which affects children's freedom of movement. Its cushioning mechanism is relatively monotonous and cannot adapt to different impact conditions.

[0004] As a special fluid, the non-Newtonian fluid (shear-thickening fluid) exhibits unique rheological properties, whose viscosity changes with the external force. For example, under a fast and intense impact, the non-Newtonian fluid can rapidly increase its viscosity and exhibit solid-like properties, effectively absorbing and dissipating the impact force. Under a slow and gentle external force, it maintains its low viscosity and exhibits good flexibility and fluidity. This property of "strong under high force and weak under low force" gives it great potential for application in the field of buffer protection. Non-Newtonian fluids have also been used to a certain extent in other fields.In the field of military protection, the flexible bulletproof vest, developed based on the shear-thickening properties of non-Newtonian fluid, overcomes the disadvantages of conventional, hard, and heavy bulletproof vests. Upon impact, it quickly solidifies, effectively withstands the impact, and returns to its soft state after impact. However, there is currently no application of non-Newtonian fluid as a buffer material in the field of chest armor for children. Object of the invention

[0005] The object of the invention is to provide a Taekwondo chest protector for children that uses a non-Newtonian fluid as a buffer material to solve the above technical problem.

[0006] The Taekwondo chest protector for children comprises a supporting part and a buffer part, wherein the buffer part has a buffer layer, a sealing layer and a fixing layer, wherein the buffer layer is a buffer layer made of non-Newtonian fluid, wherein the sealing layer wraps and seals the buffer layer and forms a strip structure, wherein the strip structure is arranged in the fixing layer so that a strip-shaped buffer part is formed, wherein this buffer part is arranged in the transverse direction on the supporting part, wherein when the supporting part is worn, the central portion of the buffer part lies on the chest of the wearer, wherein the two ends of the buffer part run along the supporting part towards the back of the wearer and cover at least the sides of the back of the wearer's chest.

[0007] The Taekwondo chest protector for children of the invention uses a buffer section with a buffer layer made of a non-Newtonian fluid to protect children's bones. The buffer section is designed in the form of a strip structure. Due to the shear thickening property of the non-Newtonian fluid, the impact force when a frontal or side impact hits the child's chest is dissipated along the buffer section with a strip structure. This prevents excessive local impact forces and injuries to the child's chest, thus protecting the internal organs in the chest area. The sealing layer allows the non-Newtonian fluid to be contained within the strip structure without leakage.

[0008] Furthermore, several buffer parts are provided and arranged one above the other on the support part.

[0009] Furthermore, the sealing layer is a sealing bag made of ABS plastic, with the buffer layer arranged in the sealing bag.

[0010] Furthermore, the fastening layer is formed by sewing a fabric onto the supporting part.

[0011] Furthermore, the fabric is a nylon fabric.

[0012] Furthermore, the fastening layer can be opened so that the strip structure can be removably arranged in the fastening layer.

[0013] Furthermore, the fastening layer has an upper fabric layer and a lower fabric layer, wherein a zipper is provided between the upper fabric layer and the lower fabric layer or the upper fabric layer covers part of the lower fabric layer.

[0014] Furthermore, binding parts extend from both sides of the carrying part, whereby when worn, the binding parts are connected and fixed to each other on the wearer's back so that the buffer part extends to the wearer's back.

[0015] Furthermore, the binding parts are connected to each other by Velcro or the binding parts are provided with cord holes and are connected to each other by cords.

[0016] Reference numerals: 1 carrying part, 2 buffer part, 21 buffer layer, 22 sealing layer, 23 fixing layer, 231 upper fabric layer, 232 lower fabric layer, 24 zipper, 3 binding part Description of the preferred embodiments

[0017] Referring to the accompanying drawings, the Taekwondo chest protector for children of the invention will be described.

[0018] As in the Fig. As shown in Figures 1 to 4, the children's Taekwondo chest protector includes a support portion 1 and a buffer portion 2. The buffer portion 2 has a buffer layer 21, a sealing layer 22, and a fixing layer 23. The buffer layer 21 is a buffer layer 21 made of non-Newtonian fluid. The sealing layer 22 wraps and seals the buffer layer 21, forming a striped structure. The buffer layer 21 is wrapped by the sealing layer 22 so that it can be formed into a striped structure to prevent the non-Newtonian fluid from leaking out of the buffer portion 2. The striped structure is arranged in the fixing layer 23, thus forming a striped buffer portion 2. This buffer portion 2 is arranged in the transverse direction on the support portion 1. When the support portion 1 is worn, the central portion of the buffer portion 2 rests on the wearer's chest.The two ends of the buffer part 2 extend along the support part 1 toward the wearer's back, covering at least the sides of the back and the wearer's chest. In the event of a frontal impact, the impact force is dissipated to both sides along the strip structure due to the shear-thickening property of the non-Newtonian fluid, thus distributing the impact force along the strip structure. The child's chest bones are not damaged by excessive local impact forces. Likewise, in the event of a side impact, the force can be dissipated along the strip structure to the other side, thus protecting the bones on the child's sides.

[0019] Several buffer parts 2 are provided. They are arranged one above the other on the support part 1. As shown in the Fig. 1 and Fig. As shown in Figure 2, in the present embodiment, three buffer parts 2 are arranged one above the other. Likewise, the number of buffer parts 2 can be increased or decreased as needed for support parts 1 of different sizes.

[0020] The invention provides a preferred embodiment in which the sealing layer 22 is a sealing bag made of ABS plastic. The buffer layer 21 is arranged within the sealing bag. The ABS plastic has good mechanical properties and can absorb energy through elastic deformation upon instantaneous impact pressure. Furthermore, it can inhibit the deformation expansion of the non-Newtonian fluid, thus preventing the container from rupturing.

[0021] The fastening layer 23 is formed by sewing a fabric onto the supporting part 1. The fabric is a nylon fabric through which the striped structure is attached to the supporting part 1.

[0022] The fastening layer 23 can be opened so that the strip structure can be removably arranged in the fastening layer 23.

[0023] As in Fig. As shown in Figure 3, the invention provides an embodiment of the fastening layer 23, wherein the fastening layer 23 comprises an upper fabric layer 231 and a lower fabric layer 232. A zipper 24 is provided between the upper fabric layer 231 and the lower fabric layer 232. The strip structure is removably arranged in the fastening layer 23 by opening and closing the zipper 24.

[0024] As in Fig. As shown in Figure 4, the invention provides a further embodiment of the fastening layer 23, wherein the fastening layer 23 comprises an upper fabric layer 231 and a lower fabric layer 232. The upper fabric layer 231 covers a portion of the lower fabric layer 232. In this embodiment, the upper fabric layer 231 and the lower fabric layer 232 form a pocket-like structure. The strip structure is removably disposed within the pocket.

[0025] As in the Fig. 1 and Fig. 2, binding parts 3 extend from the two sides of the carrying part 1. When worn, the binding parts 3 are connected and fixed to each other on the back of the wearer so that the buffer part 2 extends to the back of the wearer.

[0026] The binding parts 3 are connected to each other by Velcro fasteners, or the binding parts 3 are provided with cord holes and connected to each other by cords.
