Description

Technical Field

[0001] The utility model relates to the field of protective gear, and more specifically, it relates to a bio-based TPE protective gear. Background Art

[0002] A protective gear refers to a tool for protecting against injuries during sports. Among them, a knee pad is a type of protective gear, which is fixed on the leg to ensure the safety of the knee.

[0003] In order to improve the protection effect of some knee pads, the knee pads will cover the knee and the part of the calf near the knee. Since the area covered by the knee pads on the leg is relatively large, it is necessary to increase the air permeability of the knee pads. The shape of the ventilation holes on the existing knee pads is generally a hexagonal hollow hole. However, the area of the hexagonal hollow hole is relatively large, which weakens the structural strength of the knee pads more. As a result, when the knee pads are impacted, the possibility of deformation or rupture is relatively large.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a bio-based TPE protective gear.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a bio-based TPE protective gear, including a knee pad main body, on which there are a number of hexagonal hollow holes, there are a number of intersecting strips arranged horizontally or vertically on the knee pad main body, and any one hollow hole is divided by two mutually perpendicular intersecting strips to form four trapezoidal hollow holes. There is also a diamond hole located between two hollow holes on the knee pad main body.

[0007] The utility model is further arranged as: the thickness of the middle part of the knee pad main body is greater than the thickness of the left and right sides of the knee pad main body.

[0008] The utility model is further arranged as: the opening areas of all trapezoidal hollow holes on the outer side of the knee pad main body are equal, and the closer the trapezoidal hollow hole is to the middle part of the knee pad main body, the smaller the opening area of the trapezoidal hollow hole on the inner side of the knee pad main body.

[0009] The utility model is further arranged as: the knee pad main body includes a knee part and a leg protection part, and there are split grooves on both the left and right sides of the knee pad main body, and the split grooves are located at the boundary between the knee part and the leg protection part.

[0010] The utility model is further arranged as: a groove is formed by stamping at the most prominent position of the knee part facing outward, and a marking block is adhered in the groove.

[0011] The utility model is further arranged as: the knee pad main body is made of bio-based TPE material

[0012] In summary, the utility model has the following beneficial effects: By adding two intersecting strips that are perpendicular to each other, the protective performance of the knee pad is increased while ensuring the aesthetics of the protective gear. The intersecting strips divide the hexagon into four trapezoidal cutouts. Compared with the relatively large cutout holes in the hexagon, the smaller trapezoidal cutouts can enhance the protective ability. When subjected to an impact, the trapezoidal cutouts with a larger contact area can reduce the direct contact between the human body and the impact, thereby weakening the harm caused by the impact to the human body and ensuring the protective ability of the knee pad main body. Moreover, the smaller trapezoidal cutouts have a relatively small impact on the structural strength of the knee pad main body, enabling better maintenance of the strength and buffering ability of the knee pad. The setting of the diamond-shaped holes compensates for the ventilation area lost by the knee pad main body due to the setting of the intersecting strips, ensuring that the sum of the areas of all diamond-shaped holes and trapezoidal cutouts is equal to the area of the original cutout holes, and guaranteeing the ventilation effect of the knee pad main body.

[0018] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0019] Bio-based TPE protective gear, such as Figure 1 and Figure 2As shown in the figure, it includes a knee guard main body 1. There are several hollow holes arranged in a hexagonal shape on the knee guard main body 1. There are several intersecting strips 2 arranged horizontally or vertically on the knee guard main body 1. The intersection points of two intersecting strips 2, one vertical and one horizontal, are always located at the center of the hollow hole. Any one hollow hole is divided by two intersecting strips 2 perpendicular to each other to form four trapezoidal hollow holes 3. There is also a diamond-shaped hole 4 located between two hollow holes on the knee guard main body 1. The area of the diamond-shaped hole 4 is similar to the area of the trapezoidal hollow hole 3. The area of the trapezoidal hollow hole 3 is also less than 1 / 4 of the area of the hollow hole. Therefore, the intersecting strip 2 itself has a width, and the width of the intersecting strip 2 is at least 1 / 4 of the side length of the hollow hole. In this application, a relatively stable hexagon is used as the basic shape of the design, and two mutually perpendicular intersecting strips 2 are added, which increases the protection performance of the knee guard on the basis of ensuring the beauty of the protective gear. The intersecting strip 2 divides the hexagon into four trapezoidal hollow holes 3. Compared with the hollow hole with a larger area in the hexagon, the trapezoidal hollow hole 3 with a smaller area can increase the protection ability. When being impacted, the trapezoidal hollow hole 3 with a larger contact area can reduce the direct contact between the human body and the impact, thereby weakening the harm of the impact to the human body and ensuring the protection ability of the knee guard main body 1. And the trapezoidal hollow hole 3 with a smaller area weakens the structural strength of the knee guard main body 1 less, and can better maintain the strength and buffering ability of the knee guard. The setting of the diamond-shaped hole 4 makes up for the ventilation area lost by the knee guard main body 1 due to the setting of the intersecting strip 2, so that the sum of the areas of all the diamond-shaped holes 4 and the trapezoidal hollow holes 3 is equal to the area of the original hollow hole, ensuring the ventilation effect of the knee guard main body 1. The diamond-shaped holes 4 are arranged in a linear array on the knee guard main body 1. The length of the diamond-shaped hole 4 in the horizontal direction is greater than the length in the vertical direction. Such a setting makes several diamond-shaped holes 4 on the same horizontal line form a deformation line, making it convenient for the knee guard main body 1 to deform along this line.

[0020] As Figure 3 and Figure 4 shown, the thickness of the middle part of the knee guard main body 1 is greater than the thickness of the left and right sides of the knee guard main body 1. The middle part of the knee guard main body 1 is used to fit with the knee and the outer side of the leg, and the most protruding position of the knee guard outward is concentrated in the middle part of the knee guard main body 1. Since the instantaneous impact force received by the knee guard main body 1 is generally also concentrated in the middle part of the knee guard main body 1, ensuring the thickness of the middle part of the knee guard main body 1 can ensure the anti-impact ability of the knee guard main body 1. The area of the opening of the trapezoidal hollow hole 3 on the outer side of the knee guard main body 1 is greater than or equal to the area of its opening on the inner side of the knee guard main body 1. The areas of the openings of all the trapezoidal hollow holes 3 on the outer side of the knee guard main body 1 are equal. The closer the trapezoidal hollow hole 3 is to the middle part of the knee guard main body 1, the smaller the area of the opening of the trapezoidal hollow hole 3 on the inner side of the knee guard main body 1. Such a setting makes the fitting area between the inner side of the knee guard main body 1 and the skin large, increasing the contact surface of the knee guard main body 1, especially in the middle part of the knee guard main body 1, and weakening the harm of the impact to the human body. The area of the opening of the trapezoidal hollow hole 3 on the outer side of the knee guard main body 1 is relatively large, preventing the trapezoidal hollow hole 3 from being blocked and ensuring the ventilation effect of the trapezoidal hollow hole 3.

[0021] As Figure 1 , Figure 3 and Figure 4 shown, the knee brace main body 1 includes a knee part 5 and a leg guard part 6. Split grooves 7 are formed on both the left and right sides of the knee brace main body 1. The split grooves 7 are located at the boundary between the knee part 5 and the leg guard part 6. The volume of the protective gear is increased at the place where the force may be the most, and the volume of the protective gear is reduced at the place where the force is the least, so as to increase the shock absorption and protection effect of the protective gear as much as possible and reduce the weight brought to the wearer by the protective gear. Moreover, between the knee part 5 and the leg guard part 6 is the position where the knee brace main body 1 has a relatively large deformation. The split grooves 7 reduce the width of this part of the position, facilitating the knee brace main body 1 to bend along its length direction. A groove 8 is formed by stamping at the outermost protruding position of the knee part 5. A logo block 9 is adhered in the groove 8. The logo of the production company can be printed on the logo block 9, which is convenient for the publicity of the company. And the logo block 9 is located at the most prominent position of the knee part 5. This position is generally the position where the impact is the greatest. Closing the trapezoidal louvre hole 3 with this logo block 9 helps to further improve the impact resistance of this position. In the trapezoidal louvre hole 3 located in the knee part 5, the area of the opening on the inner side of the knee part 5 of the trapezoidal louvre hole 3 closer to the groove 8 is smaller.

[0022] As Figure 1 shown, the knee brace main body 1 and the logo block 9 are both made of bio-based TPE material. Bio-based TPE has the characteristics of being renewable and degradable, and its performance is not much different from that of petroleum-based TPE. In this application, bio-based raw materials are selected without reducing the performance of TPE, improving the utilization rate of bio-based raw materials, achieving the purpose of reducing carbon emissions, and reducing the dependence of TPE on petroleum resources.

[0023] The above is only the preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
