Description

Technical Field

[0001] The invention belongs to the field of daily necessities, and in particular relates to a pair of cycling gloves. Background Art

[0002] With the rise of national fitness, cycling has become one of the more popular sports. During cycling, it is often necessary to wear corresponding gloves to protect the hands and increase the friction between the gloves and the handlebars.

[0003] Currently, most gloves on the market are made of fabric, and the part that contacts the handlebars often has a protruding structure to increase friction. However, this type of gloves has the following defects:

[0004] 1. Due to the long-term contact with the handlebar during use, the air permeability and perspiration wicking properties are poor, which not only affects comfort, but also increases weight after absorbing sweat, affecting flexibility. At the same time, after absorbing sweat, it is easy to breed bacteria, mold, odor and other undesirable phenomena, which cannot meet the needs of users for repeated use;

[0005] 2. There is almost no support. In the event of an emergency, such as a fall, the palms of both hands are likely to come into direct contact with the ground, unable to form an effective cushioning protection effect, and are very likely to cause serious abrasions due to friction with the ground. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved cycling glove.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A cycling glove comprises a finger wearing portion, a palm wearing portion and a wrist wearing portion, wherein the finger wearing portion, the palm wearing portion and the wrist wearing portion all comprise a lattice structure elastomer and a breathable fabric layer, wherein the lattice structure elastomer is a thermoplastic elastomer, and the breathable fabric layer is located inside the lattice structure elastomer.

[0009] Preferably, the porosity of the thermoplastic elastomer is 5% to 40%, and the elastic resin layer is formed on the thermoplastic elastomer, wherein the elastic resin layer is formed at least in the internal pores of the thermoplastic elastomer and is bonded to the thermoplastic elastomer. This improves breathability, increases comfort, and is lighter while providing the required impact cushioning.

[0010] Furthermore, an elastic resin layer is formed on the outer surface of the thermoplastic elastomer, further improving the strength, elasticity, and impact resistance of the thermoplastic elastomer without increasing the overall thickness.

[0011] According to a specific embodiment and preferred aspect of the present invention, the pressure required for the finger wearing part, wrist wearing part, and palm wearing part after the elastic resin layer is formed respectively when they are compressed to a deformation of 50% gradually decreases, wherein the pressure required for the palm wearing part when it is compressed to a deformation of 50% is greater than 30N.

[0012] Preferably, the mass of the elastic resin layer is 5% to 50% of the mass of the thermoplastic elastomer; and / or the density of the thermoplastic elastomer is 0.7 to 1.4 g / cm³. This improves the strength, elasticity, and impact resistance of the thermoplastic elastomer while ensuring sufficient elastic cushioning capacity while optimizing weight reduction.

[0013] Preferably, the elastic resin constituting the elastic resin layer has a hardness of greater than 50A Shore hardness and less than 40D Shore hardness, a viscosity at 25° C. less than 12000 cP, a tensile strength of greater than 5 MPa, and an elongation at break of greater than 120%.

[0014] According to another specific embodiment and preferred aspect of the present invention, air ducts are formed on the thermoplastic elastomer, wherein the air ducts corresponding to the finger-worn portion and the palm-worn portion are interconnected; or alternatively, the air ducts corresponding to the finger-worn portion, the palm-worn portion, and the wrist-worn portion are interconnected. Multiple air ducts are designed into the lattice structure. During cycling, the pressure differential caused by speed allows air to flow into the air ducts, keeping the palms dry and cool to a certain extent.

[0015] Preferably, the finger wearing portion, the palm wearing portion and the wrist wearing portion form a back of hand portion and a palm portion, and the air duct is correspondingly arranged in the palm portion.

[0016] Furthermore, the back of the hand and the palm of the hand are integrally formed to form the finger wearing part, the palm wearing part and the wrist wearing part, and the impact buffering force formed by the palm of the hand is greater than the impact buffering force formed by the corresponding back of the hand.

[0017] In some specific embodiments, the area formed by the lattice units of the finger wear portion is s1, the area formed by the lattice units of the wrist wear portion is s2, and the area formed by the lattice units of the palm wear portion is s3, where s3>s2≥s1; the rod diameter of the lattice units of the finger wear portion is d1; the rod diameter of the lattice units of the wrist wear portion is d2; and the rod diameter of the lattice units of the palm wear portion is d3, where d1≥d2>d3; the sintering density of the finger wear portion is ρ1; the sintering density of the wrist wear portion is ρ2; and the sintering density of the palm wear portion is ρ3, where ρ1≥ρ2>ρ3. To protect the palm and balance the force applied by the hand during gripping, the 3D-printed lattice structure has variations in lattice structure, density, and rod diameter, so that the glove can effectively absorb and rebound the impact force of the hand when it suddenly contacts the ground, thereby protecting the hand.

[0018] According to another specific embodiment and preferred aspect of the present invention, the breathable fabric layer is made of a breathable and skin-friendly elastic fabric; or / and the thermoplastic elastomer is made of thermoplastic polyurethane. In this case, the elastic fabric is also provided with ventilation holes. The combination of the ventilation holes and the lattice structure can guide air into the pores of the 3D-printed lattice structure blocks, effectively improving the overall air permeability and perspiration-wicking properties, and enhancing the wearing comfort. Thermoplastic polyurethane elastomers have excellent elasticity, outstanding load-bearing capacity, oil resistance, water resistance, and mildew resistance. They are also thermoplastic and easy to 3D print. Therefore, they are extremely suitable for the use environment, performance requirements, and process requirements of cycling sports.

[0019] In some specific embodiments, the thermoplastic elastomer is formed by coating the thermoplastic elastomer with a treatment liquid containing an elastic resin or a raw material thereof and a curing agent.

[0020] In some specific embodiments, the coating treatment is carried out by spraying, dipping or electroplating. During the coating treatment, the treatment liquid is allowed to penetrate into the internal pores of the lattice structure elastomer.

[0021] In some specific embodiments, the coating treatment time is 5-20 minutes, and the heating treatment time is 3-12 hours.

[0022] Furthermore, the mass concentration of the elastic resin in the treatment liquid is 30-60%, and the mass concentration of the curing agent is 1%-10%. In some specific embodiments, the mass concentration of the elastic resin in the treatment liquid is 40-55%, and the mass concentration of the curing agent is 2%-5%.

[0023] In some specific embodiments, the heat curing is performed at a temperature of 80-100° C., and the coating process and heat curing are performed once, or after one time, are repeated 1-3 times.

[0024] Furthermore, the resin constituting the thermoplastic elastomer is selected from thermoplastic polyurethane resin, thermoplastic polyethylene resin or a combination of both.

[0025] In some embodiments of the present invention, the elastic resin constituting the elastic resin layer is a combination of one or more selected from polyurethane resin, acrylic resin, and silicone resin.

[0026] Through research, the inventors discovered that by fully contacting a lattice structured elastomer with a treatment solution containing an elastic resin or a raw material for forming the elastic resin and a resin curing agent, and then heating and curing it, the elastic resin forms an elastic resin layer within the internal pores of the lattice structured elastomer and on the outer surface of the lattice structured elastomer. The elastic resin and the lattice structured elastomer are cured, bonded, and composited, filling the internal pores of the lattice structured elastomer, thereby obtaining a thermoplastic elastomer with excellent mechanical properties. At the same weight, the thermoplastic elastomer has higher compression resistance; while achieving the same compression performance, the material has a lower weight. Furthermore, the elastic resin layer on the outer surface of the lattice structured elastomer can reduce the surface roughness of the material, resulting in a smooth surface.

[0027] Lattice-structured elastomers are produced through 3D printing. By adjusting parameters such as 3D printing temperature and laser energy, the sintering density and porosity of the lattice-structured elastomer can be controlled, thereby controlling the penetration depth and quality of the elastic resin. The lower the temperature and laser power, the higher the porosity of the printed lattice-structured elastomer, the higher the elastic resin content in the thermoplastic elastomer, and the better the compression resistance of the thermoplastic elastomer.

[0028] In some specific embodiments, the parameters used are as follows: temperature of 80-140° C., laser power of 30-100 W, scanning rate of 4000-10000 mm / s, and scanning spacing of 0.1-0.3 mm.

[0029] Meanwhile, the lattice cell structure constituting the lattice structured elastomer is not particularly limited and can be a common cube, star, octagon, hexagon, rhombus, tetrahedron, and the like.

[0030] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0031] The present invention adopts a combination of thermoplastic elastomer and breathable fabric layer, which can not only absorb and balance the impact force during cycling, increase the friction between the handlebars, better protect the rider's hands, and reduce the risk of abrasions when the hands rub against the ground; but also has high ventilation and moisture-wicking performance, even if the hands sweat, it will not have a negative impact on the comfort of use. In addition, the lattice structure can also make the whole glove naturally return to its original contour, the internal impact force changes little, the gloves can be reused and have a long service life.

[0042] Example 1

[0043] like Figure 1 As shown, the cycling gloves involved in this embodiment include a finger wearing part 1, a palm wearing part 2 and a wrist wearing part 3.

[0044] Combine Figure 2 As shown, the finger wearing part 1, the palm wearing part 2 and the wrist wearing part 3 all include a lattice structure elastomer A and a breathable fabric layer B, wherein the lattice structure elastomer A is a thermoplastic elastomer, and the breathable fabric layer B is located inside the lattice structure elastomer.

[0045] In this example, the thermoplastic elastomer has a porosity of 5% to 25% and is 3D-printed using TPU. This material offers excellent elasticity, outstanding load-bearing capacity, and resistance to oil, water, and mold. Its thermoplastic properties make it easy to 3D print, making it ideally suited to the cycling environment, performance, and process requirements.

[0046] The material of the breathable fabric layer B is a breathable and skin-friendly elastic fabric.

[0047] Specifically, ventilation holes k are provided on the elastic fabric. The combination of ventilation holes and lattice structure can guide air into the pores of the 3D printed lattice structure blocks, effectively improving the overall air permeability and perspiration, and improving the wearing comfort.

[0048] The elastic fabric features small holes, with the opening ratio per unit area varying according to the load-bearing ratio of the corresponding parts. This is done to match the support of the underlying 3D-printed lattice structure, while also effectively increasing overall breathability and comfort.

[0049] Air ducts f are formed in the thermoplastic elastomer, connecting the finger wear portion 1 and the palm wear portion 2. Multiple air ducts are designed into the lattice structure. During cycling, the pressure difference caused by speed allows air to flow into the ducts, keeping the palms dry and cool to a certain extent.

[0050] The finger wearing part 1, the palm wearing part 2 and the wrist wearing part 3 form the back of the hand and the palm part, and the air duct f is correspondingly arranged in the palm part.

[0051] The back of the hand and the palm are integrally formed to form the finger wearing part 1, the palm wearing part 2 and the wrist wearing part 3, and the impact buffering force formed by the palm part is greater than the impact buffering force formed by the corresponding back of the hand part.

[0052] The finger wearing part 1 includes five finger sleeves, and the fingers are respectively inserted into the five finger sleeves.

[0053] In this example, an air duct f is formed on each fingertip, and an air duct f is formed on the palm of the palm wearing part 2 and is connected to the air duct f on the fingertip.

[0054] In this example, an elastic resin layer is formed on a thermoplastic elastomer. Part of the elastic resin layer is formed within the thermoplastic elastomer's internal pores and bonds with the elastomer, while the remaining portion is formed on the thermoplastic elastomer's outer surface. This improves breathability, increases comfort, and reduces weight, while still providing the required impact cushioning. Furthermore, it further enhances the thermoplastic elastomer's strength, elasticity, and impact resistance without increasing the overall thickness.

[0055] After the elastic resin layers are formed, the pressure required for the finger wearing part, wrist wearing part, and palm wearing part to be compressed to 50% of their deformation gradually decreases, among which the pressure required for the palm wearing part to be compressed to 50% of its deformation is greater than 30N.

[0056] The elastic resin constituting the elastic resin layer has a hardness of 50A Shore hardness or higher and 40D Shore hardness or lower, a viscosity of less than 12000 cP at 25° C., a tensile strength of 5 MPa or higher, and an elongation at break of 120% or higher.

[0057] The mass of the elastic resin layer is 10% to 30% of the mass of the lattice structure elastomer, thereby improving the strength, elasticity, and impact resistance of the thermoplastic elastomer and optimizing the weight reduction while ensuring sufficient elastic buffering capacity.

[0058] The area formed by the lattice unit of the finger wearing part 1 is s1, the area formed by the lattice unit of the wrist wearing part 3 is s2, and the area formed by the lattice unit of the palm wearing part 2 is s3, where s3>s2≥s1; the rod diameter of the lattice unit of the finger wearing part 1 is d1; the rod diameter of the lattice unit of the wrist wearing part 3 is d2; the rod diameter of the lattice unit of the palm wearing part 2 is d3, where d1≥d2>d3; the sintering density of the finger wearing part 1 is ρ1; the sintering density of the wrist wearing part 3 is ρ2; the sintering density of the palm wearing part 2 is ρ3, where ρ1≥ρ2>ρ3.

[0059] In order to protect the palm and balance the force when grasping the grip, the 3D printed lattice structure has changes in lattice structure, density, and rod diameter, so that the glove can effectively absorb and rebound the impact force of the hand when it suddenly contacts the ground, thereby playing a role in protecting the hand.

[0060] Furthermore, the lattice cell structure constituting the lattice structured elastomer is not particularly limited and can be a common cube, star, octagon, hexagon, rhombus, tetrahedron, and the like.

[0061] Meanwhile, in this example, the molding process of cycling gloves includes the following steps:

[0062] 1) Using thermoplastic polyurethane (TPU) as the raw material, a lattice structure elastomer was 3D printed by powder sintering. The process parameters were a main temperature of 100-120°C, a laser power of 60W, a scanning rate of 4000-10000mm / s, and a scanning spacing of 0.3mm.

[0063] 2) 93 parts by mass of a commercially available 50% polyurethane resin solution and 7 parts by mass of an isocyanate curing agent were mixed and dispersed uniformly using a high-speed stirrer to obtain an impregnation treatment solution, wherein the polyurethane resin had a hardness of 70A, a viscosity of 10,000 cP at 25°C, a tensile strength of 10 MPa, and an elongation at break of 210%.

[0064] 3) The printed lattice structure elastomer was immersed in the impregnation treatment solution prepared in step 2) for 8 minutes, taken out and dried, and then placed in a vacuum oven at 80±2°C for curing for 2.5 hours to obtain a composite material sample.

[0065] The sintering density and porosity of the lattice structured elastomer obtained at different scanning rates, as well as the weight and pressure at 50% compression deformation of the lattice structured elastomer before and after polyurethane resin treatment are shown in Table 1 below:

[0066] Table 1

[0067]

[0068]

[0069] As shown in Table 1 above, by controlling the process parameters of 3D printing, the sintering density and porosity of the lattice structure elastomer can be adjusted. The higher the content of polyurethane resin in the thermoplastic elastomer, the more the compression resistance of the composite elastomer material is improved.

[0070] Example 2

[0071] like Figure 3 As shown, the cycling gloves involved in this embodiment include a finger wearing part 1, a palm wearing part 2 and a wrist wearing part 3.

[0072] The structures of the specific finger wearing part 1, the palm wearing part 2 and the wrist wearing part 3 are the same as those in Example 1, and the differences are as follows.

[0073] In this example, a lattice structured elastic body A is formed on the breathable fabric layer B, and the lattice structured elastic body A is located at the palm portion of the cycling glove.

[0074] At the same time, an air duct f is formed between the two lattice structure elastomers A on the palm wearing part 2, and the air duct f on the palm wearing part 2 is connected to the air duct f on the wrist wearing part 3.

[0075] The lattice structure elastic body A of the finger wearing part 1 is disconnected from the lattice structure elastic body A on the palm wearing part 2 to form an air duct f. This design not only has a good ventilation effect, but also makes it easier for the palm to grasp the handlebars.

[0076] In addition, in this example, the molding process of cycling gloves includes the following steps:

[0077] 1) Using thermoplastic polyurethane (TPU) as the raw material, a lattice structure elastomer was 3D printed by powder sintering. The process parameters were a main temperature of 100-120°C, a laser power of 68W, a scanning rate of 6000mm / s, and a scanning pitch of 0.2mm.

[0078] 2) 97 parts by mass of a commercially available acrylic resin solution having a concentration of approximately 50% and 3 parts by mass of a curing agent, 4,4'-methylenebis(2-methylcyclohexylamine), were mixed and dispersed uniformly using a high-speed stirrer to obtain an impregnation treatment solution, wherein the acrylic resin had a hardness of 65A, a viscosity of 10,000 cP at 25°C, a tensile strength of 12 MPa, and an elongation at break of 180%;

[0079] 3) Soaking the printed TPU lattice structure elastomer in the impregnation treatment solution for 10 minutes, taking it out and drying it, and then curing it in a vacuum oven at 80°C for 5 hours to obtain a thermoplastic elastomer sample;

[0080] 4) Place the solidified sample in the immersion treatment solution again, soak for 10 minutes, spin dry, and solidify.

[0081] That is, the lattice structure of the thermoplastic elastomer formed in the formed thermoplastic elastomer has two layers of elastic resin on the surface. At the same time, the weight of the thermoplastic elastomer is increased from 22g before treatment to 25g, and the pressure when the material is compressed to 50% is increased from 32N before treatment to 46N. The density of the prepared thermoplastic elastomer is 1.1g / cm 3 .

[0082] Example 3

[0083] like Figure 4 As shown, the structure of the cycling gloves involved in this embodiment is the same as that of Example 3, and the differences are as follows.

[0084] In this example, the lattice structure elastic body A is formed only on the palm wearing part 2 and the wrist wearing part 3, and the air ducts f are interconnected.

[0085] Meanwhile, in step 4) of the thermoplastic elastomer-based cycling gloves molding process, after soaking for 10 minutes, drying, and curing, step 4) was repeated. The resulting thermoplastic elastomer had a lattice structure with three elastic resin layers formed on its surface. Simultaneously, the weight of the thermoplastic elastomer was increased from 22g before treatment to 26g, and the pressure at 50% compression set was increased from 32N before treatment to 61N. The resulting thermoplastic elastomer had a density of 1.15g / cm³.

[0086] Therefore, the present invention has the following advantages:

[0087] 1. This application combines a lattice-structured elastomer with an elastic resin coating, allowing the elastic resin to penetrate the internal pores of the lattice-structured elastomer and tightly bond the two. Unexpectedly, without compromising the advantageous properties of the lattice-structured elastomer, the material's compression resistance is significantly improved, while maintaining the same volume and only slightly increasing its weight. Compared to lattice-structured elastomers without the elastic resin coating, the thermoplastic elastomer of this application achieves significantly smaller volume and lighter weight while achieving the same compression resistance. At the same weight, the thermoplastic elastomer of this application exhibits significantly higher compression resistance.

[0088] 2. The preparation process of the thermoplastic elastomer of this application uses 3D printing to prepare a lattice structured elastomer, and adopts a coating and curing process. On the one hand, by adjusting parameters such as 3D printing temperature and laser power, the sintering density and porosity of the lattice structured elastomer can be controlled, thereby controlling the depth and quality of elastic resin penetration, and ultimately the degree of improvement in the thermoplastic elastomer's compression properties. Therefore, thermoplastic elastomers with various properties can be flexibly prepared to meet the personalized needs of various application scenarios. On the other hand, the coating and curing process achieves a more complete and tight bond between the lattice structured elastomer and the elastic resin coating, which helps to improve the strength and service life of the thermoplastic elastomer.

[0089] 3. The present application adopts a combination of thermoplastic elastomer and breathable fabric layer, which can not only absorb and balance the impact force during cycling, increase the friction between the handlebars, better protect the rider's hands, and reduce the risk of abrasions when the hands rub against the ground; but also has high ventilation and moisture-wicking performance, even if the hands sweat, it will not have a negative impact on the comfort of use. In addition, the lattice structure can also make the whole glove naturally return to its original contour, the internal impact force changes less, the gloves can be reused and have a long service life.

[0090] 4. Air ducts are formed in the thermoplastic elastomer, where the air ducts corresponding to the finger-worn and palm-worn sections are interconnected; alternatively, the air ducts corresponding to the finger-worn, palm-worn, and wrist-worn sections are interconnected. Multiple air ducts are designed into the lattice structure. During cycling, the pressure differential caused by speed allows air to flow into the ducts, keeping the palms dry and cool to a certain extent. To protect the palms and balance the force applied when gripping the grip, the 3D-printed lattice structure features variations in lattice structure, density, and rod diameter. This allows the glove to effectively absorb and rebound the impact of sudden contact with the ground, thus protecting the hands.

[0091] 5. The elastic fabric is also equipped with ventilation holes. The combination of ventilation holes and lattice structure can guide air into the pores of the 3D-printed lattice blocks, effectively improving overall breathability and perspiration wicking, and enhancing wearing comfort. Thermoplastic polyurethane elastomer has excellent elasticity, outstanding load-bearing capacity, oil resistance, water resistance, mildew resistance, good thermoplasticity, and easy 3D printing processing. Therefore, it is extremely suitable for the use environment, performance requirements, and process requirements of cycling.

For numerical ranges, the endpoints of each range, the endpoints of each range and individual point values, and the individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered to be specifically disclosed herein.
